. ons, or other vehicles.

into staples b 011 the side of the elevator-trough sides of the elevatoi trough.

; journaled Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improved scraper and elevator,

, showing the same applied to a sled, parts of shown in longitudinal section.

the elevator being broken out and others Fig. 2 is a plan view of the lower part of the same. Fig. 3 is a longitudinal elevation of a modification of the same, parts being broken out and others shown in section.

An elevatortrough, A, is j ournaled to swing in two standards, B B, on a sled, O, or on a wagon or other vehicle. The lower end of the elevator-troughAis curved or bent to adapt it to rest flat on the ground and to form ascraper, and at the lower end of the elevator-trough the sides of the said trough are provided with outwardly-swinging wings, A, which can each be held inclined outward more or less from.

the sides of the elevator trough by means of a brace-hook, a, having its bent ends passed and on the outer surface of the wings A; but

thewings A at the desired inclination to the A short distance above the lower end of the elevatorltrough A atransverse shaft, D, is in the same, 011 eachjend of which a driving-wheel, E, is mounted rigidly, which drivingwheels are provided on the outer rims with transverse ribs e 01 spikes. On the illner surface of their rims the driving-wheels E are provided with cogs which engage with .pinions I mounted on a transverse shaft, F, journaled on the trough, on which shaft sprocket-wheels G are mounted, one adjoining the trough. Like s p rocket-wheels, G, are mounted on a transverse shaft .at the upper end of the elevator-trough and over the sprocket-wheels.

I On eachside ofthetrough endless chains Hpass, which are united by curved transverse scraperblades J, which are of such length that they can extend from the chains H to the bottom 1 of the trough A. At the upper end the trough A is provided in its bottom with an "opening, (I, through which the dirt, snow, 850., that has been raised can drop into the box I, which rests on three transverse rollers, K, on the sled O, of which rollers the one nearest the front of the sled is slightly higher than the one nearest the rear of the sled. A rope or chain, L, fastened to the front end of the box I, is wound on a drum,L, 011 a shaft, M, pro vided with a crank handle, M,and with a ratchet-wheel, N, 011 which aspring-pawl, N, rests. A bar, 0, is pivoted at or near its middle to jaws O, projecting upwardly from the platform of the sled, at its rear end, and is provided at the end projecting beyond the rear end of the sled with an upwardly-projecting hook, g. The box I is provided with a block, h, on the front end of its bottom.

The box I is provided at its rear end with a gate, 1, hinged at its upper end and locked in position by a suitable locking device, I. A rope or chain, the upper part of the elevatortrough,is wound on a drum, Q, on a shaft, R, journaled in standards R on the top of the sled, which shaft is provided with a crank-handle, R and a ratchet-wheel, S, against which a springpawl, S, rests. In the modification shown in Fig. a cog-wheel, '1, is mounted 011 the shaft D,

with the driving-wheels E, and engages with a pinion, F, in the same manner as described above; but in this case -I have not provided an elevator-trough, but an elevator-box, U, which is provided at 'its middle with'a longitudinal partition, V, which forms the floor upon which the material is carried upward.

At its upper end the box U is provided with Q, attached to the bottom 0t" a spout, W, through which the material can pass into. the box placed below it.

the construction is the same as that of the elevator described above.

The sled G or other vehicle can be propelled by means of horses or steam-poweaand the Otherwise vator is not in use, its upper end is pulled down by means of the rope Q, so that the rim of the driving-wheels E, near the lower end of the elevator-trough, cannot come in contact with the ground. If the elevator-is to be used, the rope Qis released to permit thelower end of the elevator to drop to the ground, whereby the driving-wheels Ewill comein contact with the ground. According to the width of the space to be scraped by the elevator, the wings A are swung outward more or less, to iiicrease theopening at the lower end or mouth of the elevator. If the vehicle is moved forward, the driving-wheels E will be revolved in the direction of the arrow a, and the elevator-chain will. be moved in the direction of its arrow-that is, the upper part will move downward and the lower part will move upward, and the scrapers on the lower part will,

raise the sand, dirt, dust, &c., up in the elevator-trough until it drops through the opening d into the box I. d

The device shown in Fig. 3 0perates in a similar manner, only in this case the upper part of the elevator moves upward and the lower part moves downward, and thestones, dirt, &c., are carried up on the transverse partition V and drop through the opening WV into the box I on the sled.

The elevator shown in Figs. 1 and 2 is to be used for finer material-such. as snow, dust, dirt, sand, gravel, sawdust, &c.and the elevatorshown in Fig. 3 is to be used for coarser material, such as stones, blocks of ice, lumps of dirt, &c. The box I is held from. sliding off the end of the sled by the hook g at the outer end of the bar 0, against which hook the outer transverse edge of the bottom of the box rests. If the box I has been filled as much as desired, and it is to be dumped, the hook g at the end of the bar 0 is slightly depressed to permit the bottom of the box to pass over it, and the box is permitted to slide down the transverse r ollersK by unwinding the rope L from thedrum L. The box I then slides down over the rear end of the sled or other vehicle until the block h catches on the front end of the bar 0. and is thereby prevented from sliding off of the sled entirely. As the bar 0 is pivoted on the up-.

wardly-proj ecting jaws 0, it can swing on the same, and the box I will swing downward with the bar 0, and if the gate P has been released the contents of the box can slide out of the rear end of the same. The box I is then drawn on the sled again by winding the rope L on the drum L.

Having thus full y described my invention I claim as new and desire to secure by Letters Patent- 1. Avehicle having thereon a box, I, standards B B, and a trough, fA, pivoted in the standards, said trough having its lower end bent to rest flat on the ground and form a scraper, as shown and described.

3. The combination, with a vehicle, of an elevator pivoted on the same, having its lower end adapted to scrape, and being provided with laterally-swinging wings, and of devices for locking the said wings in the desiredposition, substantially as herein shown and described, and for the purpose set forth.

4. The combination, with a vehicle, of an elevator pivoted on the same, driving-wheels journaled in the lower part of the elevator, shafts carrying sprocket-wheels journaled. in the lower and upper ends of. the, elevatortrough, and of endless chains carrying scrapers and passing over the said sprocket-wheels, substantially as herein shown and described, and for the purpose set forth.

5. The combination, with a vehicle, of the elevator-trough O, pivoted thereon, the transversely ribbedv or spikedv driving-wheels E, mounted on the shaft D, journaled in the lower part of the trough, the shaft F, the pinions F, mounted thereon, the sprocket-wheels G, the sprocket -wheels G, the chains H, and the scraper blades .1, substantially as herein shown and described, and for the purpose set forth.

6. The combinatiomwithavehicle, of an elevator pivoted on the same, a box adapted to slide over the rear end of the vehicle, and of devices for drawing the box back toward the front end of the vehicle, substantially as herein shown and described, andfor the purpose set forth.

7. The combination,with avehicle, of an elevator pivoted on the same, the box I, resting on transverse rollers K on the vehicle, and the rope L, attached to the front end of the vehicle and attached to a Windlass-drum on the vehicle, substantially as herein shown and described, and for the purpose set forth.

8. The combination,withavehicle, of an elevator pivoted on the same, the box I, resting on the rollers K, the bar 0, journaled in jaws projecting upwardly from the rear end of the vehicle, which bar is provided at its rear end with a hook, g, and of a block, h, on the under side of the box I, substantially as herein shown and described,- and for the purpose set forth.
