Application tiled July 5, 1898. Serial No. 685,192. (No model.)

To all whom it may concern.-V

Be it known that I, JAY B. RHODES, a citizen of the United States, residing at Harvey, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Street-Sprinklers, of which the following is a specification.

My invention relates to street-sprinklers of that class in which a hollow sprinkler-head is arranged to receive the water from a tank or receptacle on the cart or wagon and is provided with a laterally-apertured cap-sleeve having a sliding connection with the hollow sprinkler-head and adapted to discharge the water through its apertured side when it is projected from the sprinkler-head to an eX- tent to expose its apertured side.

Prominent objects of my invention are to provide a simple, compact, and highly-efficient construction, torvary the volume of the water discharged and to vary the direction of the discharge in a simple and reliable manner, to eectively avoid leakage .and all undesirable drip of water vfrom the sprinklerhead at such times as the discharge is cut off, to provide a construction and arrangement whereby a packing employed to prevent leakage can be adjusted or crowded up in a way to compensate for such wear as might tend to permit leakage, and to permit the sprinklerhead to be flnshed'when so desired.

To the attainment of the foregoing and other useful, ends, the laterallyapertured sprinkler-cap sleeve is arranged to receive and slide upon an'V open-end portion of the hollow sprinkler-head, so that when projected therefrom it will provide a laterally-apertu red chamber, which receives the water from the hollow sprinkler head 'and discharges v the same through its apertnred side. By this arrangement the laterally-apertured side of the sprinkler-sleeve will be closed when it is over the outer side of the hollow sprinkler-head and opened when it is moved out of register therewith. By arranging the sprinkler-cap sleeve to receive and slide over the open-end portion of the hollow sprinkler-head I am also enabled to provide packing which while serving to effectively prevent leakage islalso covered and protected by the lsprinkler cap sleeve, and which, as hereinafter set forth,can

also be adjusted with reference to such wear as may otherwise permit objectionable leakage -and waste of water. As a fu rther simple and desirable arrangement the sprinkler-cap sleeve is operated by a rod which is supported by and extended longitudinally through the hollow sprinkler-head,` such arrangement also permitting the sprinkler-cap sleeve to be rotatably adjusted, when so desired, in an easy and convenient way.

In the accompanying drawings, Figure l represents in side elevation a sprinkler cart l or wagon with my improved sprinkler device.

Fig.2 is a rear elevation of Fig. 1. Fig. 3 shows the tank, drivers seat, and treadle in front elevation. Fig. 4. is a section taken longitudinally and centrally through one of the sprinkler-heads and adj uncts on a larger scale than in the preceding iigures. Fig. 5 shows the sprinkler-cap sleeve in central longitudinal section and a portion ot the hollow sprinkler-head in side elevation. Fig. 6 is a crosssection on line a: in Fig. 5. section on line y y in Fig. 4.

' The sprinkler cart or wagon may be of any ordinary or approved construction and is provided, as is usual, wit-h a suitable water tank or reservoir A. This vehicle is desirably provided with a couple of sprinkler devices, respectively arranged at opposite sides'of its rear end portion and adapted to discharge the water transversely to the line of progression ofthe Vehicle and in rear of the rear wheels thereof.

Each sprinkler device comprises a hollow sprinkler-head B, which is in open communication with the water-tank through the medium of a lateral pipe or duct C. The form of the sprinkler-head may be varied without departing from my invention, it being preferable, however, to adopt a cylindric or substantially cylindric shape.

The sprinkler-head is provided with a longitudinally-sliding sprinkler-cap sleeve D, adapted and arranged to receive the rear end portion of the sprinkler-head and itted to slide longitudinally thereon Vfor the purpose of establishing and cutting oft the discharge of water at will. The sprinkler-cap sleeve is formed with a cylindric body portion d and a closed rear end d and has its cylindric body Fig. 7 is a cross- IOO portion fitted to slide upon the rear end portion of the sprinkler-head, it being understood that as a matter of course the form of such body portion of the sprinkler-cap sleeve in cross-section could be modified with reference to any change in form of the sprinklerhead.

The sprinkler-cap sleeve can be moved forwardly or retracted on the sprinkler-head in order to cut oif the discharge, and it can also be moved rearwardly for the purpose of establishing the discharge in quantity proportional to the extent to which it is projected back from the sprinkler-head. When the sprinkler-cap sleeve is projected back from the sprinkler-head, it serves, in effect, to rearwardly extend the latter, and at such time it also forms a chamber which receives the water from the sprinkler-head preparatory to discharging the [iuid onto the street. To permit such ultimate discharge of the water, the body portion of the sprinkler-cap sleeve is laterally apertured either by perforations d2 or by transversely slotting it. When the sprinkler-cap sleeve is retracted or moved forward upon the sprinkler-head, as in Fig. 4, l

its apertured portion will be brought over and closed by an imperforate portion of the sprinkler-head, which latter, broadly considered, may be understood to comprise the sprinkler-head proper and certain adjuncts or fixtures thereon hereinafter described. When the sprinkler-cap sleeve is moved back or projected from the sprinkler-head, as in Fig. 5, it will receive water from the sprinklerhead and discharge the same in volume proportional to the extent to which its apertured portion is opened, in which way the volume of the discharge can be readily regulated by the device employed for longitudinally adjusting the sprinkler-cap sleeve upon the sprinkler-head. As a simple and efficient device for thus longitudinally adjusting the sprinkler-cap sleeve a rod or pitman E is extended longitudinally through the sprinklerhead and attached to the closed end of the sprinkler-cap sleeve, the forward end of this rod being connected with suitable operating means-for example, a swinging hanger or lever F, attached to the. vehicle and connected by a rod G with a lever or treadle H, located at the forward end of the vehicle in position to be operated by the driver. With such arrangement the sprinkler-head serves to guide and support and partially inclose the longitudinally-movable rod E. To prevent leakage, the rod can work through suitablyarranged packing or a stuffing-box I at the forward end of the sprinkler-head, and to further guide and support the rod it may also work through a bearing b, arranged within the rear portion of the sprinkler-head.

A further advantage involved in the foregoing-described construction resides in the fact that while the sprinkler-cap sleeve can in an extremely simple way be adjusted longitudinally for the purpose of establishing,

Varying, and cutting off the discharge it can also be rotatively adjusted for the purpose of varying the extent to which the Water is thrown laterally from the vehicle. To such end the rear terminal portion of the adjusting-rod E extends through a corresponding opening in the closed end of the sprinklercap sleeve and is threaded to receive a clampnut K, which latter can be tightened up to rigidly clamp the sprinkler-cap sleeve against a shoulder on the rod and also loosened to permit the sprinkler-cap sleeve to be turned about the axis of the rod to any desired extent, the nut after such adjustment on the part of the sprinkler-cap sleeve being of course again tightened up against the latter, so as to secure it upon the rod. In this way I provide the sprinkler-head with au apertured cap-sleeve adapted for both longitudinal and rotary adjustment, so as to meet all sprinkling requirements, and, further, I provide extremely simple means for effecting and permitting such adjustments. The rod E could of course be connected with the lever F by a swivel-joint, in which case the sprinkler-cap sleeve could be adjustably turned by turning the rod; but as a preferred and simpler arrangement the sprinkler-cap sleeve is adj ustably attached to the rod and the latter connected with the lever bya sliding pivotal joint having sufficient play to compensate for the swing of the lever.

As a matter of further improvement the sprinkler-head comprises a hollow body portion having as an adjunct or fixture thereon a separately-made clamping piece or plate L, consisting of an apertu red disk or plate which is arranged opposite and secured to the rear end of the hollow body portion of the sprinkler-head by bolts M. This construction permits an annular packing P to be clamped between the clamping-plate L and the rear end of the hollow body portion of the sprinklerhead as a means for effectively guarding against leakage of water between the peripheral surface of the body portion of the sprinkler-head and the body portion of the sprinkler-cap sleeve which slides thereon, it being observed that the packing thus employed is arranged to attain such end. A further advantage attending such arrangementis that the bolts can be adjusted to clamp the packing between the plate L and the sprinklerhead proper, and hence when the packing or contacting surfaces of the sprinkler-cap sleeve and sprinkler-head become worn as the result of operating the sprinkler-cap sleeve all Wear of such parts can be readily compensated for by simply tightening up the bolts to an extent to crowd the packing and cause it to bulge laterally. To insure the lresult lastl mentioned, the packing is desirably fitted in an oset either in the clamping-plate or in the rear end of the body portion of the sprinkler-headas, for example, in the clampingplate, as illustrated.

The foregoing-described arrangement of IOO IOS

IIO

clamping-plate L also permits an annular packing R to be fitted to the inner side of the closed end of the sprinkler-cap sleeve and arranged to seat against the plate L when the sprinkler-cap sleeve is retracted upon the sprinkler-head, as in Fig. 4, thereby further guarding against leakage, particularly when the sprinkler-cap sleeve is apertured to an extent to leave any part of its apertured portion opposite the periphery of the plate L or the packing P when the sprinkler-cap sleeve is retracted upon the sprinkler-head.

As to matters of detail, the plate L can be constructed as a spider having an annular seating portion l for the two packings, a central bearing l for the adjusting-rod E, and radial arms or web portions Z2, adapted to provide bearings for the bolts. With this arrangement the plate L will have segmentalshaped openings Z3, through which water from the sprinkler-head proper can pass into the chamber provided by the sprinkler-cap sleeve when the latter is projected from the sprinkler-head. The rear end of the body portion of the sprinkler-head may have a construction similar to the plateL-that is to say, it may have an annular internally-arranged iange providing a seating surface for the packing P and a central bearing b connected with such flange by arms or web portions b', arranged to leave spaces between them for the free passage of water. In order to flush the sprinkler-head, the rod can be moved back to an extent to cause the sprinkler-cap sleeve to entirely clear the sprinkler-head, and thereby permit a full flow of water.
