`Application filed March 2, 1916.
`To all who're it may corwern:
`Be it known that we, CORNELIUS D. FAR-
`MER and GEORGE N. FRAZER, Sin, GEORGE N.
`FRAZER Jr., and WASH B. FABMER, citizens ,
`5 of the llnited States, and residents of Eu-
`ene, in the county of Lane and State of
`regon, have invented a certain new and
`useful
`Improvement
`in Street—Flushing
`Nozzles, ‘of which the following is a specifi-
`lo cation.
`1
`‘
`One of the principal‘ objects of our in-
`vention is to provide a nozzle for sprinkling
`or flushing machines, of improved construc-
`tion, designed to'eject a stream of water to
`15 cleanse and wash a pavement in a manner
`more thorough and advantageous than that
`attained by nozzles of ordinary construction.
`Another object of the invention resides in
`the provision of a nozzle of the class de-
`20 scribed, in which one of the parts of the
`nozzle may be removed, so that the interior
`of ‘the nozzle may be exposed whereby it
`may be machined in finishing the nozzle,
`and whereby it may be cleaned without re-
`25 moving the nozzle from the sprinkling ma-
`chine.
`‘
`A further object of the invention is to
`provide a nozzle of
`the class described
`- which will be extremely simple, durable,
`so eflicient
`in.-operation, and inexpensive to
`manufacture.
`.
`_
`_
`With _these and other objects in view
`which will become apparent as the descrip-
`tion proceeds,'the~ invention resides in the
`35. construction, combination, and arrangement
`of parts hereinafter more fully described
`and claimed, and illustrated in the accom-
`panying drawing in which like characters
`of reference indicate like parts throughout
`40 the several figures, of which-
`Figure 1 represents a top plan view of a
`nozzle constructed according to our inven-
`tion.

`.
`
`Fig. 7‘ represents a view in section taken
`longitudinally and vertical]
`on the plane
`indicated by the line 7——7 0 Fig. 6.
`. Fig. 8 represents a front edge elevational
`view of a modified form of nozzle.
`The nozzle head 5 illustrated in Figs. 1
`to 5 inclusive,
`includes a preferably flat
`floor 6, vertical side walls 7 and a slightly
`rounded or curving top wall 8. From the
`forward edge of the bottom 6, the top wall
`slopes backwardly and upwardly, so that
`the height of the nozzle gradually decreases
`toward the forward edge. A threaded
`nipple 9 is formed at the rear end of the
`nozzle, for engagement with a supply pipe
`10. The nozzle is provided with two front
`faces .11 and 12 arranged in angular relation
`with respect
`to each other and inclining
`backwardly from the apex 13 of the nozzle.
`From the points 14, at which the faces ter-
`minate,
`the side walls Yiconverge toward
`the rear end 9 of- the nozzle. The slot or
`opening 15 provided in the front faces 11
`and 12, increases in width from the apex 13
`of the nozzle toward the ends 14 of the faces,
`and this formation of the slot -and the ar-
`rangement of the faces 11 and 12 with re-
`spect to the nozzle head, provides for the
`distribution of the water to the greatest ad-
`vantage in attaining the desired result.
`For instance, the faces being arranged‘ in
`an
`lar relation to each other, the Water
`wil emerge in a fan-like stream, and by’
`reason of the fact that the width of the slot
`15 increases slightly toward its ends, the
`volume and force of the stream at its edge
`portions will be just as great as the volume
`and force of the stream at its middle por-
`tion, and thus the entire sheet or stream of
`water issuing from the nozzle, will be uti-
`lized and no portion of its force lost.
`In manufacturing the nozzle, we desire to
`make it with either its bottom or its top
`removable, and in the embodiment shown
`in Figs. 1 to 5 inclusive, we have illustrated-
`the nozzle as being equipped with a remov-
`able top 16. The top may be secured in
`place with stud bolts, cap bolts, clamps, or
`other suitable fastening means. The-‘ joint
`between the top and the main body portion
`of the nozzle may be either packed with soft
`packing of some sort, or a ground joint may
`be formed, or any other method of making
`‘the joint watertight be followed. By hav-
`ing the cap, removable, the interior of the

`
`ozzle may be machined in finishing it off,
`and furthermore, when in operation,
`the
`nozzle may be cleaned without removing it
`from the sprayer.
`As indicated in the drawing, the to) or
`cap lti is secured in place by means of olts
`17. The latter are turned through openings
`in the ca p into threaded recesses provided in
`the side walls 7 of the nozzle head.
`In the embodiment shown in Figs. 6 to 8
`inclusive, the nozzle head is more of a fan
`shape, having a curved front face 11*‘, the
`side walls 7“ curving gradually backward
`toward the nipple 9“ from the ends of the
`front face of the nozzle, The upper wall 8’
`‘in this instance,, at its forward portion:
`f(
`quite a way back from the front edge of sail
`upper wall,
`lies parallel with the bo ‘
`fl.
`wall of the sprayer head. The top wall nen
`curves upwardly, bearing away from the
`lower wall toward the rear end of the nega-
`zle.
`In this instance, the lower wall 6“ is
`shown as having a removable cap or section
`16“, secured in place by means of bolts or
`other fastening means 17“.
`In either case it
`will be understood that either the top or the
`bottom wall may be provided with the re-
`movable section, The peculiar advantage in
`the construction shown in Figs. 6 to 8 in-
`clusive is that, the stream Wlll be thrown
`out in a flat sheet, and should any obstruc-
`tions be encountered-.which might divide or
`split the sheet of water, the water will, af-
`ter passing the obstructions, unite on the
`other side of the obstruction to continue the
`sheet.
`Although we have described the preferred
`embodiments of our invention, we may de-
`sire to make such changes in the construc-
`tion, combination, and arra'ngement ofkparts
`thereof, as do not depart from the spirit of
`the invention, and the scope of the appended
`claims.
`As indicated in Figs. 3, 5, and 8, the noz-
`zle is preferably arranged at a slight angle
`out of the horizontal, as it is found this posi-
`tion insures a more perfect operation of the
`device.
`
`I/V0 claim :-
`1. A nozzle for street cleaning purposes
`having its front discharge end protruding
`forwardly at
`the center and diverging
`thence toward its sides and having in said
`discharge end a discharge opening which is
`narrowest at the apex or center of the dis-
`charge end and gradually widens thence to-
`ward the opposite sides of the discharge
`end whereby there is formed a discharge
`opening in two sections merging at the apex
`of the. discharge opening and widening
`thence toward their outer ends for securing
`a discharge laterally to the direction in
`,whicl1 the nozzle is faced to wash a pave-
`"at from the center or crown thereof down
`..oward its opposite sides, all as and for the
`purposes set orth.
`, 2. A nozzle comprising a flat lower wall
`diveggjng (iutwardly from the supply end
`,e nozzle to points adjacent the outlet
`g,,pf~"fi
`end ,,_ereof and converging sharply from
`saiifppints to the apex of the nozzle, side
`walls eii riding vertically from the diverg-
`ing portions of the lower walls, an upper
`wall conforming to the outline of the lower
`wall said walls converging from the rear to
`the front portion of the nozzle, a threaded
`nipple formed at the rear end of the nozzle
`with which the upper, lower and side walls
`merge and front faces formed on the outlet
`edges of the sharply converging portions of
`the upper and lower walls thereby lying in
`angular relation‘ one with the other,
`the
`portions of the faces formed on the lower
`wall :being of greatest height at the center
`or apex of the nozzle and constantly de-
`creasing in"=-‘hei ht toward the outer ends to
`provide a disc arge opening of constantly
`increasing width from the apex of the noz-
`zle to the outer ends of the front faces,
`whereby a sheet of water of constant force
`and volume will be ejected from the nozzle.
