`ABSTRACT
`(57]
`The bracket anchors a hydro pole or a telephone pole
`vertically on rocky ground or on ground beneath which
`are sewerpipesorelectrical conduits. The bracket con-
`sists of a number of pole-mounts each having a base
`which rests on the ground and an upright which
`contacts the pole. The pole-mounts are spaced aboutthe
`circumference of the pole and are clamped to the pole
`by means of bandsinterconnected by links. The length
`of each link is adjustable to fit poles of various sizes.
`A leg extends downwardly from the pole-mountinto a
`hole in the ground. Theleg consists of a sleeve to which
`a number of wedges are connected. A bolt extends
`downwardly from the base of the pole-mount into the
`sleeve and mates threadably with a camming plug. Ro-
`tation of the bolt causes the plug to move upwardly into
`contact with the wedges and to force them outward
`into contact with the inside wall of the hole with result-
`ing anchoring of the leg in the hole.

`
`BACKGROUND OF THE INVENTION
`
`This invention relates to brackets for anchoring poles
`such as hydro or telephone poles upright on the ground
`and moreparticularly to brackets suitable for anchoring
`poles in rocky, rugged terrain where the surfaces on
`which the poles rest need not be horizontal or on
`ground beneath which sewageorelectrical conduits are
`located where the location of the anchoring meansfor
`the brackets is extremely restricted.
`Various brackets are known for maintaining poles
`vertical on rocky ground. The brackets are connected
`to anchorbolts which are secured in holesdrilled in the
`ground adjacent to where the poleis to stand. Prerado-
`vich U.S. Pat. No. 3,514,911 and Legler U.S. Pat. No.
`4,218,858
`both referred to above, describe brackets
`suitable for this purpose.
`A shortcoming of known brackets such as those de-
`scribed in the patents referred to aboveis that they are
`generally unsuitable where the holes in which the an-
`chorbolts are secured are inaccurately located. Should
`for example those holes not extend exactly vertically
`downwardit is not possible to tighten the anchorbolts
`in the holes except with the greatest of difficulty. Simi-
`larly if the holes are not spaced apart from the poles an
`exact predetermined distance, the brackets cannot be
`secured in such a wayas to minimize lateral movement
`of the pole after the pole is attachedto it.
`The reason whythe holes must be accurately located
`is because the bracketsare held in position by elongated
`bolts which extend downwardly through sleevesin the

`brackets and into the holes. The bolts must be rotated in
`order to fasten them in the holes. Should the holes not
`be accurately located the bolts must be bentto fit into
`those holes. The greater the amount of bend the more
`difficult it is to rotate the bolts. In fact it is altogether
`impossible to rotate the bolts should the amount of bend
`be too great.
`
`SUMMARYOF THE INVENTION
`
`It is an object of this invention to provide a bracket
`whichis suitable for supporting a pole inthe most rug-
`ged, rocky country where the unevenness and the na-
`ture of the terrain makesit difficult if not impossible to
`drill holes which are exactly vertical or which are accu-
`rately placed in relation to the intended location of the
`pole. Moreover the bracket may be used to support a
`pole where the ground beneathit is occupied by a sew-
`age system or by undergroundcables.
`It is another object of this invention to provide brack-
`ets which will support poles on ground whichis not
`level. Moreover wide latitude in the location and the
`orientation of the holes is possible so that the holes can
`be located primarily where the anchorbolts will be best
`secured and only secondarily where the poleis to stand.
`Anotherobject of this invention is to provide a clamp
`whichis suitable for attaching the brackets to poles of a
`wide variation in sizes.
`A still further object of the invention is provide a
`template for facilitating the location of the holes to be
`drilled.
`These and other objects are accomplished by a
`bracket for anchoring a pole vertically on a rock-like
`support surface comprising: a plurality of pole-mounts
`having a base for resting on the support surface and a
`vertically upwardly extending upright which contacts
`the pole; clamping means for clamping the pole-mount
`to the pole; a leg which extends downwardly from the
`pole-mount for insertion into a hole which extends
`downwardly from the support surface, the leg including
`a sleeve, an inner member and expandible means, the
`sleeve having an upper end connectable to the base and
`extending downwardly therefrom,
`the inner member
`being movable within and relative to the sleeve, and
`when so moved causing lateral expansion of the expand-
`ible means with resulting anchoring of the leg in the
`hole.

`DESCRIPTION OF THE PREFERRED
`EMBODIMENT
`
`With reference to FIG. 1, the bracket of the inven-
`tion, generally 20, is shown in conjunction with a hydro
`or telephone pole 22. The bracket
`includes a pole-
`mount 24 and a pair of spaced clamps 26.
`The pole-mount is made up of a base 30 and an up-
`right 32. The base is vertically extending and has an
`under surface 34 which rests on the ground or other
`supportsurface for the pole. The upright has a generally
`U shaped cross section and is made up of a central web
`36 which contacts the pole and two spaced flanges 38
`which extend at generally right angles from the two
`side edges of the web. A numberof vertically spaced
`reinforcing ribs 40 extend between the flanges.
`With reference to FIG. 1, each clamp 26 is made up
`of a pair of bands 42a, b which are attached to the exte-
`rior flange walls and which extend circumferentially
`around the pole. An aperture is formed in each band and
`a link 44 extends between the bands and its ends pass
`through the apertures.
`The bands may be attached to the pole-mounts by
`welding or they maybe bolted to them. Alternatively as
`illustrated in FIGS. 2, 3 and 9,
`the bands 43 pass
`throughslots 48, 49 in the two flanges of the mount and
`extend outwardly from opposite sides of the same
`mount. Wherethe bandsare so formed,they are free to
`slide horizontally in the slots in the pole-mounts.
`With further reference to FIGS. 2 and9,link 44 is in
`the form of a bent rod having a threaded end portion
`44a. The opposite end 445 has a forged offset head or
`hook 445 which is removably accommodatedin a key-
`hole 45 formed in band 43a. The threaded end of the
`link is inserted in the aperture formedin band 438. A nut
`50a prevents the threaded end from being removed
`from the band. The key-hole shape ensuresthat the rod
`will not become disconnected from the band when
`assembled asillustrated in FIG. 2.
`Whenthelinks are so assembled,the links, the bands
`and the pole-mounts together extend around the entire
`circumference of the pole. The assembly restrains the
`pole from movementand the pole is thus anchored in
`position. Thereis no need touse lag bolts to preventthe
`pole-mounts from turning with respect to the pole.
`With reference to FIGS. 4 and 5, the pole-mountis
`shown in conjunction with the components whichto-
`gether form a leg for anchoring the pole-mountto the
`ground. The leg, generally 50, is made up of a sleeve 52,
`a camming plug 54 and an inner memberorbolt, gener-
`ally 56. A pair of horizontally spaced parallel slots 58
`are formed on the under surface 34 of the pole-mount.
`The slots commence at the wall 32a of the upright 32
`which faces the pole and extend at generally right an-
`gles to that wall. The slots terminate at a stop 60. The
`slots removably accommodate opposite edgesofa plate
`62 whichis attached to the upper wall of sleeve 52.
`Connected to the lower end of the sleeve by, for
`example, welding are circumferentially arranged seg-
`ments 66, the outer diameter of which being the same as
`
`4
`that of the sleeve to which the segmentsare attached. A
`spaceorslot 67 is between adjacent segments.Asillus-
`trated in FIGS. 6 and 7, each segment is shaped in the
`form of an wedge which opens upwardly and inwardly
`i.e. the wedgeis thinnest at its lower edge 66a and thick-
`ens upwardly. Those segments constitute expandible
`means for engaging the wall of the hole in which the
`sleeve is inserted. The way in which they do so is de-
`scribed below.
`Camming plug 54 serves to urge the segments 66
`between the slots outwardly or to expand. The plug has
`a frustoconical outer wall of the same slope as that of
`the inner wall of the segments. A numberofribs 68 are
`formed on its outer wall. The numberofribs is the same
`as the numberof slots 67. The width of the ribs is
`slightly less than the width of the slots and the ribs are
`so arranged that each will fit into a separate slot. As a
`result the plug can be positioned concentrically within
`the sleeve.
`The outer diameter of the conical wall of the plug at
`its upper wall 70is slightly greater than the inside diam-
`eter of the segments. The conical wall of the plug en-
`larges downwardly and,at its lower wall, its outer di-
`ameter exceedsthe inside diameter of the segments. The
`outer diameterofthe ribs is the same from the upper to
`the lowerwalls of the plug. A threaded bore 72 extends
`along the longitudinal axis of the plug.
`Bolt 56 has a shank 73 which removably passes
`through an enlarged aperture 74 in base 30 and down-
`wardly through the sleeve. Asillustrated in FIG. 5,
`head 76 of the bolt has an outer diameter whichis larger
`than the width of the aperture so that it cannot pass
`through the aperture.
`With reference to FIG. 6 and 7, the lower portion of
`the shank is threaded at 78 and those threads mate
`threadably with the threads in the bore of plug 54. The
`ribs 68 of the plug are in the slots between segments 66
`and will prevent the plug from rotating as the bolt is
`rotated. Rotation of the bolt will accordingly cause the
`plug to rise on the shank of the bolt from the position
`shownin FIG. 6 to the position shown in FIG. 7, In the
`latter figure, the conical wall of the plug which contacts
`the inside wall of the segments causes them to move
`radially outwardly of the longitudinal axis 80—80 of the
`sleeve and into contact with the wall 82 of the hole in
`which thesleeveis located.
`Further upward movement of the plug causes the
`segments to more firmly contact the inside wall of the
`hole and to cause the sleeve to become more and more
`solidly anchoredin the hole.
`With reference to FIG.8,bolt 56 is rotated by oscilla-
`tion of handle or ratchet 82 which is removably con-
`nected to the upper end of a socket extension 84. A
`socket 86 at the lower end engages the headofthe bolt
`and causesit to rotate when the handle is oscillated.
`The socket extension is prevented from rocking or
`swaying whenit is being rotated by meansofpair of
`arms 88 which apply an inward pressure against
`diameterically opposite sides of an enlarged portion of
`the socket extension. The ends of the arms remote from
`the socket extension are attached to tabs 90 whichfit
`snugly into the space between the bands 42 andthe pole.
`The tabs can be withdrawn from the space and the
`socket and socket extension are removed after the bolt
`has been tightened sufficiently to anchor the sleeve in
`the hole.
`With reference to FIG. 10, a template, generally 92,
`facilitates the location of the holes to be drilled where

`the pole is to be anchored by meansofthree brackets.
`The template consists of three sleeves 94, 96 and 98.
`Sleeve 94 consiste of a lower segment 94a of outside
`diameter slightly less than the diameter of the hole
`which is to be drilled and an upper segment 945 of
`greater diameter. The other two sleeves 96, 98 have
`uniform cross-sections throughout their lengths.
`An expandible arm 100 extends between sleeves 94
`and 96 and a like arm 102 extends between sleeves 94
`and 98. Asillustrated the longitudinal axes of both arms
`are oriented at right angles to the longitudinal axes of
`the sleeves and the angle between the axes of the arms
`is approximately 60 degrees.
`A stud 104 extends inward from each sleeve. The
`length of the stud determines the distance of the hole
`from the pole in the manner described below.
`Arm 100 consists of a hollow rectangular first section
`100a whichis attached to sleeve 94. A second rectangu-
`lar section 100d is connectedto sleeve 96 andis slidingly
`received in the hollow interior of section 100a. By
`means of set screw 106 the two sections can be locked
`together in any desired position. The position of sleeve
`94 relative to sleeve 96 can accordingly be increased or
`decreased.
`The construction of arm 102 is the same andits length
`can likewise be adjusted by means of set screw 108.
`FIGS. 11 and 12 illustrate the manner in which the
`template can be used to locate the position of the holes
`which must be drilled in the ground. First a hole is
`drilled beside the place where the pole is to stand. Se-
`condly while the pole is resting horizontally on the
`ground the template is placed beside the lower end of
`the pole such that the pole is between its armsasillus-
`trated in those Figures. Thirdly the two set screwsare
`loosened to allow the length of the armsto be adjusted
`until the studs 1045 and 104c contact the outside wallof
`the pole portion. The template is then separated from
`the pole by movingit to the end ofthe pole.
`The lower segment of sleeve 94 is then inserted into
`the hole that wasdrilled in the ground. The upper seg-
`ment which has an outside diameter greater than the
`cross-section of the hole will remain on top of the hole.
`Two more holes are then drilled using the other two
`sleeves as guides. The three holes will be correctly
`located according to the size of the pole.
`In FIG. 12 the pole has a smaller outside diameter
`‘than the pole illustrated in FIG. 11 and the length of
`arms 100 and 102 are correspondingly shorterto reflect
`the smaller diameter.
`The holes which are drilled must have a cross-sec-
`tional area slightly greater than that of the outside wall
`of the sleeves so that the sleeves can be easily inserted
`into the holes. After the holes have been drilled and
`before the pole is moved into position for anchoring,
`one sleeve is attached to a pole-mount by inserting its
`plate 62 into slots 58 so that the sleeve and mount are
`connected asillustrated in FIG. 5.
`Bolt 56 is then inserted downwardly through the
`aperture 74 of the pole-mount and through the central
`bore of the sleeve and while the sleeve and the mount
`are outside the hole the plug is turned onto the lower
`end of the bolt and the bolt is rotated until the upper
`endsofits ribs are just within slots 64 of the sleeve. The
`assembly is then inserted into the hole.
`The pole is then raised by some suitable means such
`as by a mobile crane andis positioned upright beside the
`pole-mount. The other two pole-mounts are then con-
`nected to the legs in the manner described above and
`
`—_ 5
`
`40
`
`45
`
`6
`are placed in position adjacent to the other twoholes.
`The three mounts must be at the same level and shims
`maybe used for this purpose. The three pole-mounts are
`then interconnected by means of clamp 26.
`The three mounts maythen be anchored by tighten-
`ing the bolts connected to each by meansof the socket
`assembly 82, 84 and 86 with resulting stabilization and
`anchoring of the pole in an upright position. Should the
`wall of the holes crumble, the mounts will not besatis-
`factorily anchored. In such case, the mounts must be
`moved to a new location where they can be properly
`_ anchored.
`Once the pole-mounts are properly anchored, grout-
`ing of the holes is not necessary since the strength of the
`installation depends only on the jammingaction of the
`segments in the holes.
`:
`With reference to FIG. 3, it will be observed that the
`ground on which the pole is mounted is not horizontal
`and the hole in which oneleg is located is not vertical.
`All that is required is that the pole-mounts be anchored
`in the ground by meansof legs 50. When the pole is to
`be mounted on uneven ground the pole-mounts should
`be shimmed up with rocks so that
`the bands of the
`clampsare horizontal. After the pole is clamped to the
`assembly, the shims may be removed since the pole is
`supported by the pole-mounts and legs and not by the
`weight of the pole on the ground. Backfilling or grout-
`ing of the holes in which the legs are located are not
`necessary.
`Since the bracket of the invention does not require
`any grout or cement
`to maintain it
`in position,
`the
`bracket may be removed after use. To do so, the pole
`must be held upright by meansof, for example, a crane
`and the three bolts must be loosened. As the bolts are
`loosened, the bolt head will move upward from the base
`of the bracket. A sharp blow to the bolt head will move
`the bolt downward and release the camming plug from
`the segments 66 of the sleeve. The entire assembly can
`then belifted easily from the hole.
`Thebracket of the invention is designed to allow for
`variations in the size of the outer diameter of the pole.
`Asillustrated in FIG. 4, aperture 74 in the base of the
`pole-mount is elongated and allows the pole-mount to
`‘be moved backward and forward to accommodate
`poles of larger or smaller diameter. In addition by rea-
`son of the elongated apertures, the leg to which the pole
`is attached need notbe vertical. The aperture allows the
`bolt which passes throughit to be oriented in different
`directions. FIG. 3 illustrates this.
`The clamp can likewise accommodate polesofdiffer-
`ent diameters. As illustrated in FIG. 2, the effective
`length of each link can be changed by meansofthe nut
`whichis turned onits threaded end portion. By advanc-
`ing the nut toward the hook, for example, the effective
`length of the link is shortened. Whenthelink is in the
`assemblyillustrated in FIG. 2, the area bounded by the
`links and bandsis reducedasthe effective length of the
`links is reduced. Conversely the area is increased so that
`a pole of larger diameter can be accommodated simply
`by increasing the effective length of each link in the
`assembly.
`In the event that the links cannot be lengthenedsuffi-
`ciently to accommodatea large pole all that is necessary
`is to substitute longer links for the existing links in the
`assembly of links and bands.

`bands of the clamp. The only component that may not
`accommodate poles of all sizes is the link. For that
`reasonit is advisable on a jobsite to stocklinksofdiffer-
`ent sizes. However because of the adjustability of the
`links very fewdifferent sizes of links are necessary.
`In generalit is preferable for the pole-mounts which
`support a pole to be about 120 degrees apart. However
`this is not essential. Where the terrain makes this impos-
`sible the design of the clamps is such that the spacing
`between adjacent pole-mounts can be adjusted accord-
`ing to the spacing between pole-mounts,It is not neces-
`sary that the effective length of the links in an assembly
`of links and bands be the same.
`Preferably the pole-mount and the cammingplug are
`cast in malleable iron and the clamps and the remaining
`componentsofthe legs are formed of galvanizedsteel.
`It will be understood of course that modifications can
`be madein the preferred embodiment described herein
`without departing from the scope and purview of the
`invention as defined in the appended claims.
`The embodimentsof the invention in which an exclu-
`sive property or privilege is claimed are defined as
`follows:
`1. A bracket for anchoring a pole vertically on a
`support surface comprising: pole-mount having a base
`for resting on the support surface and a vertically up-
`wardly extending upright which contactssaid pole, said
`base having a lowersurface; clamping meansfor clamp-
`ing said pole-mount to said pole; a leg which extends
`downwardly from said pole-mountfor insertion into a
`hole which extends downwardly from said support
`surface, said leg including a sleeve, an inner member
`and expandible means, said sleeve having an upper end
`connectable to said base and extending downwardly
`therefrom,said inner member being movable within and
`relative to said sleeve and when so moved causing lat-
`eral expansion of said expandible means with resulting
`anchoring ofsaid leg in the hole.
`2. The bracket as claimed in claim 1 further including
`a plate formed at the upper endofsaid sleeve, said base
`having a pair of spaced apart slots formed on the lower
`surface thereof for removable accommodation of said
`plate.
`3. The bracket as claimed in claim 1 wheresaid ex-
`pandible means comprisesa plurality of wedges having
`lower edges being thinnest at their lower edges and
`thickening upwardly.
`4. The bracket as claimed in claim 1 wherein said
`clamping means comprises a link having a hook at one
`end which is removably connected to a first pole-mount
`and a threaded end at
`the other end which passes
`through an aperturein a second pole-mount adjacent to
`
`8
`said first pole-mount and which is secured therein by
`threaded means.
`5. A bracket for anchoring a pole vertically on a
`rock-like support surface comprising: a plurality of
`pole-mounts each having a base for resting on the sup-
`port surface and a vertically upwardly extending up-
`right which contacts said pole, said base having a lower
`surface; clamping means for clamping said pole-mount
`to said pole; a leg which extends downwardly from said
`pole-mount, each leg having a free lower end portion
`and whichincludes a sleeve and an inner member,said
`sleeve having an upper end connectable to said base and
`extending downwardly therefrom, said inner member
`being movable within and relative to said sleeve, the
`free lower end portion of each leg remote from the
`pole-mount having meanslaterally expandible by said
`relative movementsuchthat said leg can be anchoredin
`a hole which extends downwardly from said support
`surface.
`6. The bracketas claimedin claim 5, further including
`a plate formedat the upper endofsaid sleeve, said base
`having a pair of spaced apart slots formed on the lower
`surface thereof for removable accommodation ofsaid
`plate.
`7. The bracket as claimed in claim 5, wherein said
`expandable means comprisesa plurality of wedges hav-
`ing lower edges being thinnest at their lower edges and
`thickening upwardly.
`8. The bracket as claimed in claim 5, wherein said
`clamping means comprises a link having hook at one
`end which is removably connectedto a first pole-mount
`and a threaded end at
`the other end which passes
`through an aperture in a second pole-mountadjacent to
`said first pole-mount and which is secured therein by
`threaded means.
`9. The bracket as claimed in claim 5, wherein said
`clamping means comprises a clamp including a link
`having a hookat one end for removable interconnection
`to a first pole-mount, said link further including a
`threaded portion adjacent to an opposite end thereof for
`threadable connection to a second pole-mount.
`10. The bracket as claimed in claim 9, further com-
`prising a plurality of bands which extend circumferen-
`tially around said pole and which pass through slots
`formed in said pole-mounts, each of said bands having a
`first aperture formedin a first end thereof and a second
`aperture formed in a second endthereof, the hook of a
`first link being accommodatedin said first aperture and
`the threaded portion of a second link being accommo-
`dated in said second aperture, and means for removably
`maintaining the threaded portion in said aperture.
