vmachine; and it consists of novel means for elevating the dirt, Sac., and directing the same to a chute leading to a place of collection of said dirt, te., a gatewhich may be placed in truck of the machine, to the sides of which are the path of the bucket, so as to receive the contents thereof, and then to be removed from said path to permit the unobstructed passage of said bucket, and other details of construction, as will be hereinafter set forth, the novel features being pointed out in the claims.

Figure'l represents a top or plan view of a street-sweeping machine embodying my invention, certain parts of the frame of themachine having been removed. Fig. 2 repre- Sents a partial side elevation and partial vertical section thereof. Fig. 3 represents a side elevation of a detached portion, showing a certain member thereof in a different position from that shown in Fig. 2.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the secured brackets B,on thelower ends of which latter-is mounted the rotary brush C, which is adapted to direct dirt,'&c., from the street into the primary receptacle D, whichdepends from the truck A and is firmly secured thereto and is in Icommunication with the vertical casing E, which latter is supported on said truck and the cross-bar F.X thereon. On the shaft' F of said brush is the sprocket-wheel G, around which passes the sprocket-chain H, the latter passing around the sprocketwheel J on the counter-shaft K, which is mounted in hangers L on the truck A, 'said shaft K having also connected with it the spur -wheel M, which gears with the spurwheel N, the latter 'being firmly secured to the axle P of the machine, said axle in the present case being those of the hind wheels, it being evident that when the machine is in motion rotation is imparted to the wheel N and from thence to the Wheel M, the sprocketwheel J, the chain H, and the sprocket-wheel Gr, whereby the brush C is rotated thus sweeping the dirt, &c., of the street into the receptacle D, as has been stated. The shaft K has sliding motions in the hangers L as its'bearings, so that it may be moved to the right and left, and thereby place the wheels M andN in and out of gear, by which provision the power of theV aXle P is not communicated to the brush and elevator, and thus the latter remains inoperative. When, however, said shaft K is moved to the right, the wheels M and N are placed into gear, and rotation of the brush and elevator is thereby effected. In order to impart said sliding motions to the shaft K, I employ the elbow-or elbow-arm Q, which has one limb freely engaging with said shaft K between collars Q' Q' thereon, and the other limb, R passing freely through'the adjacent hanger L and is connected with the lever S, the latter being mounted on the truckAand connected with the rod T, the latter being attached to the lever U, which is mounted adjacent to thedrivers seat, so that the driver can conveniently cause the operation of said shaft K in order to throw the brush Ointo and out of engagement with and from the aXle P through the -intermediate mechanism, as is evident.

On the shaft K is the sprocket-wheel V,

around whichv passes the sprocket-chain W,

the latter also passing around the sprocketwheel X, which is mounted on the standards Y, which are supported within the receptacle D and casing E and furthermore held by the brace Y', which is connected with the frame of the machine. The shaft Z of said sprocketwheel X also carries the sprocket-wheel A', around which passes the endless sprocketchain B', the latter also lpassing e around the sprocket-wheel C', mounted on the bottom of said standards 4sprocket-chain B are the elevator-buckets D', which in their motions are adapted to enter the receptacle D and then rise therefrom to Y. Connected with said the top of the casing E, when they overturn and are adapted to discharge their contents into a chute E', which is connected with the upper portion of the casing E and the rear portion of the truck A and is in communication with the easing E by the opening F' on the rear side of the latter. In said opening F' is a gate G', which is adapted to be engaged by the elbow-lever H', which is mounted on the side of the casing E and adapted to have one limb, H3, engaged at intervals by the arm J', which is connected with and projects radially from the shaft Z, its other limb, H4, being adapted to engage with the under side of the gate G', so as to elevate the same, as shown in Fig. 2, it being noticed in Fig. 3 that the gate is adapted to lower, whereby the contents of the overturned elevator-buckets drop on said gate and are directed into the chute J', after which the gate is raised so as to permit the downward passage of said bucket without said gate affording an obstacle thereto. The rear of the chute E' opens into the chamber H2 on the frame of the truck or machine,said chamber containing a box J', which is adapted to receive dirt, &e., as it leaves the chute E', it being made removable from said chamber H2, so that the dirt, &c., deposited therein may be taken elsewhere.

The operation is as follows: The machine is advanced, and as the shaft K is rotated by the gearing employed motion is communicated to the wheel V, the chain IV, and the wheel X, whereby as the buckets D' dip into the dirt, &c., deposited in the receptacle D by the brush C they convey their contents to the top of the casing E, when they overturn and dump said contents upon the gate G', the latter being in the position shown in Fig. 3. Then as the arm J' engages the adjacent limb of the lever H' and depresses the same the other limb bears upwardly against the under side of the gate G' and lifts the latter to the position shown in Fig. 2, thus placing the same out of the path of the descending bucket. Then the arm J' clears the lever H', when the gate drops and is again projected below the neXt advancing bucket, as in Fig. 3, when said bucket is overturned and discharges its load upon said gate, thus directing the dirt, &c., into the chute E', as before, after which the lever H' is again engaged by the arm J', so as to elevatethe gate, as in Fig. 2, and permit the descent of the last overturned bucket past the gate, as previously.

The machine is provided with the watertank K' and sprinkling-pipes L', the former having therein the valve M', whose stem N' may be conveniently operated from the drivers seat.

The brush C extends obliquely across the truck of the machine and has one end eXtended beyond the rim of the adjacent wheel, so as to enter a gutter of a street or roadway,

and thus sweep the same, the dirt, &e., from said gutter then being directed into the receptacle D, which is also obliquely arranged so as to include the projected end of the brush in its compass, the sweeping of the gutter thus being sidcwise, and hence made effective.

rlhe hangers B are adapted to be lengtlr ened and shortened to adapt thc brush to be vertically adjusted.

Various changes may be made in the details of construction without departing from the general spirit of my invention, and l do not, therefore, desire to be limited in each case to the same.

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