The front end of the box F, which the county of Oarleton and Province of Onlatter is adapted to be carried between the 5 tario, in the Dominion of Canada, have intwo sills and has the forward end of its botvented certain new and useful Improvements tom sharpened and shod, is thus suspended by i in Scrapingand Dumping Vehicles, (forparts the chain E from the stand D and may be of which we have obtained a patent in Canraised or lowered at pleasure. The rear end ada, No. 46,541, hearing date July 10, 1894;) of the box F, Fig. 4, is provided at each side 10 and We do hereby declare that the following with a trunnion, F, projecting axially and is a full, clear, and exact description of the journaled in the bob knee 1).

It is necessary that rear respectively, are framed two sills O O, the tongue G should be. open at the top, as one at each side. The forward ends of said the draft, (double tree or whifdetree) and the 5 sills are secured upon the bolster b of the pulley D are pivoted to the top of the bar front hob and the rear ends are mortised upon G sliding in it. To theifront end of the slid- 8 the unconnected knees, I), of the rear bob, so ing bar G is attached the. neck yoke or other that bobs and sills have a flexible connection, means of guiding it. The bottom of the said the front ends of the runners of the rear bob bar is at the rear end provided with a series 40 passing through a clevis, c, secured to the of notches, g. To the roller 1) is secured at sills, as shown in Figs. 1 and 3. Upon the one side of the tongueaspring, H, projecting go forward part of each'sill is erected a stand, D, across said bar G and adapted to engage any braced to resist a forward strain,which is proone of its notches g. The free end h of said vided at the top with a pulley, Di. Another spring is bent rearwardly and thus formed 5 pulley, D", is journaled to each sill 0 forward into afoot lever which may be readily reached of the position of the pulley D. A chain E from the drivers seat, J, which is secured has its two ends secured to the sides of the upon the forward ends of the sills 0. box F near its bottom at the forward end, The device operates as follows: Supposing passes over the pulley D, under the pulley the driver to be mounted on his seat J and the box F lowered to its traveling position, as shown in Fig. 3, then the driver may stop his horses or other draft animals, back them and at the same time depress thelever H with his foot. This allows the sliding bar G to pass rearwardly in the tongue as many notches g in the bar as may be desired and the front of the box F is thus lowered into a position adapted for scraping. As soon as the lever H is released it will press upward on the bottom of the bar G and engage the first notch g that presents itself when the bar is either sliding forward or rearward inthe tongue G. By reversing the horses now, the whole vehicle and with it the box F is moved forward and the box will scoop up the snow or whatever other material it may be desired to gather. When as much has been scooped up as is desired and it becomes necessary to draw the load away, the front of the box is raised sufficiently to enable the vehicle to move along, by depressing the foot lever H while the horses are moving forward and allowing the bar G to slide as many notches forward in the tongue as may be necessary. WVhcn it is desired to dump the load, the driver depresses the foot lever H while the horses are moving forward, the bar G, beng freed from the restraint of the lever H in the notches g, slides forward in the tongue G and the chain E is drawn forward with it, thus raising the front of the box to its highest position or to a sufficient height to allow its contents to slip off. The box may be lowered again by backing the horses and depressing the foot lever H, allowing the bar G to he slid back in the tongue G to the desired extent. The chain E is secured to the bar G by a pulley D or equivalent device in order to keep the strain on the chain even when turning.

Although specially adapted for a snow scraping and carrying device, and therefore placed on runners, the superstructure is equally available for wheels.

We claim as our invention- 1. The combination of a front bob provided with roller and bolster and a rear bob having its knees unconnected transversely, two sills framed near one end upon said bolster and mortised at the other end upon the upper ends of the knees of the rear bob, 2. box adapted to be carried between said sills, trunnions secured to the rear end of said box and journaled in the knees of the rear bob, a stand upon each forward end of said sills, a pulley at the top of each stand, a pulley at the forward end of each sill, a chain having its ends secured to the forward end of said box and passing over the pulleys at the top of the stand and under the pulleys at the sill and engaging a sliding bar in the tongue from which the forward end of the box is thus suspended, a grooved tongue or pole having its rear end secured to the roller and adapted to allow a bar to slide in the same, a bar adapted to slide in said tongue or pole and project therefrom at both ends and having the aforementioned chain secured to its rear end in a manner that it may yield laterally and having the rear portion of the lower surface notched and a spring foot-lever secured to the roller and projecting across said bar and adapted to engage said notches, substantially as set forth.

2. The combination of two sills suitably supported at the front and rear, a box adapted to be carried between said sills, a braced stand at the forward end of each sill, a pulley at the top of each stand, a pulley journaled to each sill, a chain having its ends secured to the forward end of said box and passing over the pulleys at the top of the stand and under the pulleys at the sills and having its central part engaged by a projection on a sliding bar in the tongue of the vehicle, substantially as set forth.

3. The combination of a cross piece or roller 11', a tongue or pole grooved at the top having its rear end secured in said cross piece and adapted to hold a bar slidingly, a bar adapted to slide in said tongue or pole and provided at its lower surface with a series of notches and a spring lever secured to said cross piece and projecting across said sliding bar and engaging said notches, substantially as set forth.

4. The combination of a bar held slidingly in the tongue or pole of a vehicle and controlled by a foot-lever engaging notches in the same and having the draft and means of guiding applied to it, a chain secured to the rear end of said bar by means affording lateral yield and passing over elevated pulleys and having its ends secured to a box, sills suitably supported at the front and rear, stands at the forward ends of said sills supporting said elevated pulleys and a box adapted to be carried between said sills and being suspended at the front end by said chain, substantially as set forth.

In testimony whereof we have signed in the presence of the undersigned witnesses.
