SPECIFICATION forming part of Letters Patent No. 551,208, dated December 10, 1895.

Application filed October 29,1894. Serial No. 527,247. (No model.)

T0 at whom it may concern:

Be it known that I, WILLIAM HAYWOOD, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Street Sweepers and Sprinklers, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in street sweepers and sprinklers, and my object is to construct an apparatus which shall be at all times under the control of the driver, and which shall be readily applicable for simultaneously sprinkling and sweeping either asphalt, Belgian block, or other pavements; and forthis purpose it consists of the combi nation and arrangement of parts as hereinafter set forth and claimed.

street sweeper and sprinkler embodying my invention. Fig. 2 represents a longitudinal vertical sectional view of the same. Fig. 3 represents, on an enlarged scale, a detail view of the clutch mechanism to be hereinafter referred to. Fig. 4 represents, on an enlarged scale, a perspective View of a support for certain parts of the apparatus to be hereinafter referred to. Figs. 5 and 6 represent vertical and transverse sectional views of a two-way valve employed. Y 7

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the body of the sweeper, and B designates the rear axle of thesame, which in conjunction with the front axle supports said body.

0 designates a water-tank arranged in the rear of said wagon, and having one of its sides preferably inclined.

D and E designate transverse water pipes or sprinklers which are located at the front and rear of the wagon, respectively, and provided with perforations on their under sides, the sprinkler E' being preferably located above the rotary brush or sweeper, to be hereinafter referred to, and supported by means of vertical arms or standards on side bars of the same. (See Fig. 1.)

F and G designate supply-pipes leading from said tank 0 to said pipes D and E, said' pipes being controlled by the valve H, which is controlled by the driver by means of the rod J and the handle K, so that water can be admitted to either of the sprinklers E or D, as may be desired, the valve H being so con trolled that when the passage to the sprinkler E is open, the passage to the sprinkler D is closed.

L designates bars which are pivoted at one end to the lower rear portion of the body A, while in the other ends of said bars are suitably mounted the bearings V for the journals of the rotary sweeper or brush M. The said bearings W can be adjusted relatively to the endless apron to behereinafter referred to, so that as the brush M wears out its efficienoy willnotbeimpaired. One of the jourits bearing, as seen in Fig. 4, and has attached thereto the sprocket-wheel N, which is actuated by means of the chain P, which is itself actuated by the sprocket-wheel Q, which is suitably secured to the pinion R, and revolves in unison therewith.

S designates a gear which meshes with said pinion R and is adapted to be thrown into and out of motion by means of the clutch mechanism shown in Figs. 1 and 3.

The gear S is mounted on a sleeve T, which turns freely on the rear axle B, and U U designate splines on opposite sides of said sleeve.

.V designates a clutch having the groove W I and the serrated outline or cut-away portion X, which corresponds to a similar outline of the hub of the rear wheel.

Y designates a yoke, which is pivoted at Z and has the portion A bent at right angles and engaged by the upturned end B of a rod 0, which is actuated by the driver, and it is evident that a movement in either direction of the rod B will throw the clutch V out of or into engagement with the hub of the wheel, and thus impart motion to the brush M by means of the gear and pinion and the sprocketwheels and other chains.

nals N of said brush M is extended beyond Figure 1 represents a side elevation of a The preferred construction of the two-way in communication alternately, as desired, with the ports 11 and H of the plug H said ports communicating with the tank 0, by means of the port H through a suitable conduit 11 it being understood that while I have shown the conduit H in Fig. 5 as communicating with the under portion of said tank 0, I do not desire to be limited thereto in every instance, since it is evident that the connection may be made at any other convenient part of the tank and the inlet-port of the valve may be at the side of the casing, if desired.

The parts are shown in Fig. 3 in operative position. The rear axle B has secured to that portion thereof which extends between the sides of the body A the roller D, and said axle also serves to support the upper ends of the frame, formed by the bars E and the cross-pieces F, the lower cross-piece G turning freely in said bars, and having at its ex tremities the rolls or wheels H, which contact with the ground when the device is in operation.

J designates an endless apron of suitable construction, which is adapted to carry the dirt, &c., swept upon it up into the receptacle or body A, and the inclined plate K retains the same within said body.

It will be understood that the apron J and the rotary brush M revolves in unison, the movement of each being governed by the clutch V.

The bottom of the wagon is constructed of slats L, which have their ends H weighted so that they will be normally retained in closed position, said slats being readily manipulated by means of the handles N, Fig. 1.

P designates a chain, one end of which is connected to the cross-piece Q, which is secured to the bars L, while the other end has attached thereto the weight B, said chain being suitably supported by the pulleys S mounted in a frame extending above the body of the sweeper.

T designates a connection between the bars L and E, so that any movement of the connection P will move the brush M and the apron J, as also the sprinkler E, in unison, as is evident.

The operation is as follows: \Vhen it is desired to use the sweeper on pavements other than asphalt, by letting water into the sprinkler D, on the proper manipulation of the valve H the street will be sprinkled in advance of the brush or sweeper M, and when the clutch has been thrown into the position seen in Fig. 3, and the wagon moved to the left, the brush M will rotate in the direction of the arrow, and the dirt, refuse, &c., will be thrown upon the endless apron J, and will be carried up into the receptacle A, as is evident. The wagon can be unloaded by moving the slats L into the position seen in dotted lines in Fig. 2. When an asphalt pavement is to be swept, it is desirable to wet the same as little as possible, so the sprinkler E alone is used, the operation of the other parts being the same as before. \Vhen it is desired to lift the brush M and the wheels II from the ground, it is only necessary for the driver to pull the connection P, and the parts will assume the position seen in dotted lines, Fig. l, as is evident, the pipe G rising, as it is flexible or flexibly connected to the valve II.

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