ROBERT E. PATTEN, OF BOlVDOINHAM, MAINE.

SNOW-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 289,131, dated November 27, 1883.

Application filed August 21. 1883. (No model.)

To alt whom it may concern: Be it known that 1, ROBERT E. PATTEN, a citizen of the United States, residing at Bow doinham, in the county of Sagadahoc and have invented certain new and useful Improvements in Snow-Scrapers, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinvention relates to scrapers such as are used to remove snow from the surface of the ice; and the object of my invention is to provide a scraper which can be handled by one man, instead of three, as those in common use now require, and which may be easily drawn to any required distance after being loaded. I accomplish thisresult by means of the device shown in the accompanying drawings, in which- Figure 1 shows a shows a side view.

perspective view. Fig.2 Fig. 3 shows a longitudinal section throughthe center.

A A are two sled-runners, united by the cross-bar B and the drawing-bar C. These runners are built up to a considerable height forward, the forward portion being filled in E is a scraper, made in the form of a box having one end removed. The rear end of the scraper E sits on the cross-bar B, and the pin P, fixed in the edge of the scraper, prevents it from sliding backward. On the lower edge of the scraper is secured the shoe or cutter L, made of metal or other suitable material'. The box E contains a sliding bottom, 6, which is arranged to slide backward until stopped by the pegs It. This bottom 6 rests on the cross-piece K, which is attached to the bottom of the'boX-scraper E, and on the bar J, which is attached to the middle of cross-piece Kand extends backward, resting on the cross-bar B. The cross-piece e is joined to the rear of the sliding bottom a by means of cleats,and a space is left between it and the bottom large enough to insert a handspike.

On the outside of each sled-runner are the stanchions D D, and resting in bearings on the tops of these stanchions is the. shaft F, near each end of which is a drum or pulley, G. Around these drums are wound ropes or chains, the lower ends of which are secured.

to the forward end of the box-scraper E. v

The lever I, secured to the end of shaft F by a pivot, extends backward, so that the end itself without manipulation.

may be placed cross-bar B. The ropes H H are so arranged thatwhen the end of lever I rests under the cross-bar B the end of the box-scraper E will be raised clear from the ice.

' When the scraper is to be used, the end of lever I is taken from under the end of crossbar B and the forward part of the scraper falls to the ice, as shown by dotted lines, Fig. 2. As the scraper is drawn forward, it fills The high runners increase the capacity of the scraper so long as it is left down. When the load is to be removed to a distance, the lever I is forced down and caught under the end of cross-bar B,thus raising the scraper from the ice and bringing the load on the two runners, in which position it may be moved easily to any distance. When the load is to be dumped, a handspike is inserted between the bar 6' and the sliding bottom e and the horses started ahead. The bottom is thus withdrawn, and

the load falls through. The stops R prevent the bottom from sliding entirely out. The load is dumped in a better manner than by theordinary scraper, being smoothly depositedon the ground and not heaped in a pile.

My device is capable of being used as a horse-sled as well as a scraper.

It will be seen that my scraper may be easily managed by the man who drives the horses, whereas the scraper now in common use requires the labor of three men.

I claim- 1. The snow-scraper composed of runners A A, with their cross-bar B, combined with i the box-scraper E, having sliding bottom 6, and the hoisting apparatus consisting of lever I, shaft F, pulleys G G, and ropes H H, substantially as described. i

2. In a'snow-soraper, the runners A A,

under the projecting end of combined with the box-scraper E, with its sliding bottom 6, and with its rear end resting on cross-bars B, its forward end being raised and lowered by lever I, substantially as shown and described. 3. In a snow-scraper, the runners A A, combined with the box-scraper E, the forward end of which is raised and lowered, substantially as shown and set forth,

In testimony whereof I affix my signature in presence of two witnesses.
