STREET-SPRINKLER.

SPECIFICATION forming part of Letters Patent No. 639,788, dated December 26, 1899.

Application filed October 17,1898. Serial No.698,711. (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH L. STIEBEL, a citizen of the United States of America, residing in Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Street-Sprinklers, of which the following is a specifica tion, reference being bad therein to the accompanying drawings.

My invention relates to improvements in street-sprinkling vehicles, such as wagons, cars, 850.

It relates particularly to the class of streetsprinkling vehicles provided with a disk capable of rapid rotation in a horizontal plane and having radial wings or vanes for .distributing the water, which is supplied to the disk from a tank carried by the vehicle, the disk being rotated by means of driving mechanism connecting it with the vehicle-wheels.

The object of. my invention is to provide a driving mechanism for rotating the centrifugal disk comprising shafting, bevel-gearing,

- and other parts, the peculiarities of construction being fully described and claimed hereinafter.

A furtherobject of my invention is to provide a construction which will readily accommodate itself to the vertical oscillations of the spring-supported frame carrying the watertank, while at the same time permitting the throwing in or out of gear of the driving mechanism.

In the accompanying drawings, illustrating my invention, Figure I represents asideelevation view of a sprinkling-wagon provided with driving mechanism constructed in accordance with the principles of my invention, a portion of the supporting-framework being broken away and the axle, centrifugal disk, supporting-frame, and slotted crank-arm being shown in vertical section. One of the water-supply pipes and valve is removed. Fig. 11 represents a transverse sectional view of some of the driving mechanism, taken on the dotted line a b of Fig. I. Fig. Ill represents a rear-elevation view, a portion of the tanks and other parts being removed. Fig. lV represents a rear-elevation view of the slotted crank-arm, the rock-shaft supporting it, and parts immediately connected therewith.

Similar numerals of reference indicate similar parts.

1 denotes the water-tank, 2 the rectangular tank-supporting frame, and 3 the rear or drivin g vehicle-wheels,rotatable with the rear axle 4., upon which is rigidly secured a large bevel gear-wheel 5, which meshes with a smaller similar wheel 6, rotatably secured upon the shaft 7, the forward end of which is provided with a head and is rotatably fitted in a seat provided therefor in the rear end 8 of a boxing, which is secured rotatably upon the axle 4 by the forward end 9, the two parts of the boxing being secured together by-means of suitable bolts. To prevent rearward movement of the gear 6 upon the shaft 7, it is provided with a screw 10, which is adapted to travel in an annular groove 11, provided in the periphery of the shaft 7. The rear end of the hub of the gear 6 is provided with ratchet-teeth, adapted to engage with similar teeth in the forward adjacent end of a clutch-sleeve 12, which is longitudinally movable upon the shaft 7, but is prevented from rotation thereon by a pin 13, secured in the shaft 7 and operatin g within a slot 14 in the side of the sleeve 12. The sleeve is normally forced forward by means of a coil-spring 15, encircling the shaft 7 and abutting at its rear end against a collar 16, secured rigidly upon the shaft 7.

The sleeve 12 is forced out of engagement with the gear 6 by means of a crank-arm 17, slotted at its outer end, the bifurcated parts of which are located, respectively, upon the sides of the sleeve 12 in a peripheral groove 18 provided therein. The crank-arm 17 is rigidly secured to a horizontal transverse rock-shaft 19, the ends of which are supported by brackets 20 of any desirable form and secured, respectively, to the sides of the frame 2. At one end of the rock-shaft 19 is secured a crank-arm 21, to the outer end of which is pivotally connected the rear end of a forwardly-extending connecting-rod 22, the forward end of which is pivotally connected with an upwardly-extending operating-lever 23, the lower end of which is pivoted to the frame 2. Any desirable locking device may be employed to hold the operating-lever 23 in, the position in which it may be' placed. The bifurcated ends of the crank-arm 17 are preferably curved with the concave side forward to prevent cramping with the sleeve 12 when the frame oscillates vertically upon the sup-- porting-springs 24. The rear end of the shaft 7 is rotatably mounted in a horizontal boxing 25, the center of which is provided with an opening in which is located a bevel gear-wheel 26, which meshes with a bevel gear-wheel 27, secured upon the upper end of the vertical shaft 28, which is mounted in bearings provided in a vertical frame 29, between the two side arms of which is pivoted the two ends of the boxing 25. The upper end of the frame 29 is secured to two forwardly and rearwardly adjustable brackets 30, mounted, respectively, upon the sides of the frame 2. The rear end of the shaft 7 is provided with a feather-and-groove connection with the gear 26, so that the latter may have longitudinal but not rotatory movement upon the shaft 7. To the lower end of the shaft 28 is secured the disk 31, provided upon its upper side with a series of curved radially-arranged vanes or wings adapted when the disk is rapidly rotated to throw the water received from the supply-pipes 32 horizontally in all directions. The supply-pipes 32 are connected with the tank 1 and are provided with any desirable form of shut-off valves.

My invention is operated as follows: When the sprinkling-wagon is moving forward, if it is desired to not operate the sprinkler the opcrating-lever 23 is thrown forward, thus rockin g the rock-shaft 1 9 through the intermediacy of the connecting-rod 22 and the outer crankarm 21. The rock-shaft being rocked throws the lower end of the bifurcated crank 17 rearwardly, thus forein g rearwardly the sleeve 12 and disengagingits teeth .from the teeth in the hub of the gear 6 and stopping rotation of the shaft 7. If then it is desired to operate the sprinkler, the lever 23 is released and the coilspring 15 can then force the sleeve 12 forward on the shaft 7 until the teeth of the sleeve engage the teeth of the gear-hulo 6, when the rotation of the gear 6 taken from the gear 5, which is secured to the rotating axle t, is imparted to the shaft 7 and thence to the gear 26, gear 27, and shaft 28, to which is secured the centrifugal disk 31. Rotation having been thus imparted to the disk 31, water is permitted to flow thereon through the supply-pipes 32 and is evenly distributed over a broad area. It will be observed that the forward end of the shaft 7 is pivoted to the axle 4 by means of the boxing 8 and 9 and lies in a radial line starting from the axis of the gear 5. The gear 6 will thus describe an arc of a circle, which coincides with the teeth of the gear 5 when the rear end of the shaft 7 moves vertically up or down due to the vertical oscillations of the frame 2 and frame 29. It will therefore be evident that the gears 5 and 6 will always be in proper mesh, while at the same time permitting free rotation of the shaft 7. The slot in the crank-arm 17 permits vertical movement of the said arm, while not disturbing its connection with the sleeve 12. By mounting the gear 26, as described, on the shaft 7 the shaft is free to move forward or rearward in the boxing 25 without disturbing the relative positions of the

gears

26 and 27. The pivotal mounting of the ends of the boxing 25 in the frame 29 prevents any cramping of the shaft in the boxing, the teeth of the

gears

26 and 27 being so formed that the movement of the boxing on its trunnions will not cause the gears to jam with. each other.

Various modifications of the construction shown may be made without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
