`DERRICK GIRTH LIGHT
`Frank E. Hutchison, Houston, Tex.
`Application September9, 1955, Serial No. $33,332
`~~ 1 Claim.
`(Cl. 240—~90)
`|
`
`This invention relates to improvements in a derrick light
`or the like.
`This application is a continuation-in-part of a prior ap-
`plication Serial No, 180,530, filed by the same applicant
`on August 21, 1950 and which has become abandoned.
`An object is to provide novel hanger means for suspend-
`ing the derrick light or the like from the transverse angle
`irons of a derrick which is subject to frequent jarring
`and vibrations, such novel hanger having flexible suspen-
`sion means to prevent it from being dislodged from its
`connection with the angle iron of the derrick and also
`adjustable vertical and horizontal pivotal means.
`A further object of the invention is the provision of a
`derrick light having metal parts and flexible suspension
`means by which the same may be suspended from a
`“transverse metallic member or a derrick, and which also
`embodies means for forming an electrical grounding con-
`nection between the metal parts of the light and the mem-
`ber whereby non-conducting material may be safely em-
`ployed for the flexible suspension means.
`Other objects and advantages of this invention will
`become apparent from the following description taken in
`connection with the accompanying drawings, wherein is
`set forth by way of example andillustration one embodi-
`ment of the invention.
`It is to be understood that the
`drawings and description are not to be taken by way of
`limitation and that the scope of the invention is to be
`limited only by the prior art and by the terms of the ap-
`pended claim.
`In the drawings:
`Figure 1 is a side elevational view illustrating the in-
`vention and showing the hanger or flexible suspension
`means as connected to the front and rear ends of the angle
`iron;
`Figure 2 is a front elevational view of the hanger
`or suspension means;
`Figure 3 is a cross-sectional view taken on lines 3—3
`of Figure 2; and
`Figure 4 is a fragmentary perspective view illustrating
`details of construction of the holding member or clamp
`by which the suspension means is attached to the derrick
`and showing the mannerin which the electrical grounding
`connection is established.
`Referring now more in detail to the drawings the nu-
`meral 1 designates the holiow casing of a derrick light
`adapted to be suspended from an angle iron 1a forming
`a horizontally disposed portion of the framework of a der-
`rick, or the like,
`The light casing 1 is of a type having a convex back
`14 forming a light chamber within which an electric lamp
`is disposed and provided with external lugs or ears 26
`by which the casing is adapted to be suspended from: the
`derrick in the mannerhereinafter set forth.
`The derrick light
`is adapted to be suspended from
`the derrick angle iron 1a by a bracket or yoke member
`22, whose arcuate arms 23 and 24 are formed, at their
`ends, with side bearings 25, 25 that may be pivotally or

`rotatably secured to the ears 26, 26 on the casing of the
`light, as shown in Figures 1 and 2.
`.
`_ The upper or central portion of the member 22 may
`be bent inwardly to form.a flat, horizontal surface. The
`cross-bar 27 may be rotatably mounted on the flat surface
`of the member 22 by the bolt 28 whose free end is
`passed upwardly through the vertically aligned openings
`29 and 30 in bearings in the intermediate portions of
`the bracket member and cross-bar, such bearings being
`provided by the annular groove 31 in the under side
`of the cross-bar to receive rotatably the annular, raised
`portion 32 on the flat surface of the bracket member 22.
`The nut 33 is threaded on the free end of the bolt
`28 to hold the bracket and cross-arm assembly in any
`desired horizontal position with respect
`to the derrick
`angle iron, and the cotter key 34 may be inserted in a
`bore in the upper end of the bolt 28 to prevent the nut
`33 from becoming unscrewed andlost.
`The ends 35 and 36, respectively, of the cross-arm are
`turned upwardly at right angles to form end flanges
`to receive the screws 37 and 38,
`respectively, or
`other suitable fastenings, which are provided to securely
`hold the lower ends of the impregnated belts 39 and 40
`to the respective ends of said cross-arm. The upper or
`opposite ends of said belts are secured by rivets 41 to
`the respective, front side portions of the holding member
`or clamp 42, whose rear end is bent downwardly and
`forwardly at respective right angles to snugly fit around
`the rear end portion of the horizontal flange of the angle
`iron. Clips, such as those indicated at 44, may be dis-
`posed on the belts 39 and 40 for sliding movement
`thereon,
`these clips having downturned portions 46 be-
`neath the belts which fit snugly against the front, marginal
`edge of the vertical flange of the derrick.
`The belts 39 and 40 may be formed ofelectrically non-
`conductive material and are twisted mediate their ends,
`as shown in Figures 1 and 2, so that the upper end por-
`tions of the belts lie in planes parallel to the longitudinal
`axis of the angle-iron support 1a, while the lower end
`portions of the belts lie in planes at right angles to such
`axis. By so twisting the belts and attaching them to the
`support and crossbar, the belis serve to flexibly support
`the light and prevent the transmission of jarring and vibra-
`tion from the support to the light.
`An electrical conductor, such as a wire 48 may be
`threaded through one of the flexible suspension belts, as
`the belt 39, and connected at one end to the screw 37 of
`the cross-arm end 35, and at its other end to one of the
`rivets 41, whereby an electrical connection is established
`between the framework of the light and the clamp 42.
`Suitable means, such as the screw 50 may be threadably
`carried by the clamp 42 which is engageable with the
`angle iron 1a to securely hold the clamp against displace-
`ment on the angle iron and to assure an electrical ground
`connection between the clamp and the derrick.
`In operation, the derrick light fixture may be suspended
`from the derrick angle iron without danger of it work-
`ing loose from any direction, and at the same timeits
`adjustment, either vertically or horizontally, may be
`accomplished by a manipulation of the pivotal means
`above described.
`Bythe provision of the electrical grounding connection
`between the light and the derrick it will be apparent that
`non-conducting materials may safely be used in the belts
`39 and 40.
`While the invention is disclosed in connection with
`certain specific embodiments, it will be understood that
`the sameare intended to beillustrative only, and numerous
`changes can be madein the structure and arrangement of
`the parts without departing from the spirit of the inven-
`tion or the scope of the appended claim.
`Having thus clearly shown and described the invention,

`what is claimed as new and desired to secure by Letters
`Patent is:
`The combination with a light carrying body formed of
`metal, a yoke having spaced vertically-disposed depend-
`ing arms at opposite sides of the body, means connecting
`the arms to the body for vertical angular adjustment of
`the body in the yoke, a horizontally disposed crossbar
`and means connecting the crossbar to the yoke mediate
`the ends of the crossbar for horizontal angular adjust-
`ment of the yoke on the crossbar, of spaced apart, flat,
`vertically elongated flexible members of electrically non-
`conductive material attached at their upper ends to an
`elongated horizontal metallic support at longitudinally
`spaced locations on the support and at their lower ends
`to the ends of the crossbar, the upper end portions of said
`members lying in planes parallel to the longitudinal axis
`of said support and the lower end portions of said mem-
