OOOOOOO l.)
.G. B. GRUMAN. Snow Scraping Machine.
No. 234,470. Patented Nov. 16, I880.
Urran States GEORGE B. GRUMAN, OF BRANCHVILLE, CONNECTICUT.
SNOW-SCRAPING MACHINE.
SPECIFICATION forming part of Letters Patent No. 234,470, dated November 16, 1880,
Application filed July 10, 1880.
To all whom it may concern Be it known that l, GEORGE B. GRUMAN, of Branchville, in the town of Ridgefield, county of Fairfield, State of Connecticut, have invented a new and useful Snow-Scraper, of which the following is a specification.
My invention relates to snow-scraping inachines for clearing snow from ice by the aid of steam or horse power, prepara'ory to cutting the ice into blocks for storing.
The objects are, first, to provide a machine portable, easy to manage with the team by one man, and at the same time able to carry the man so as to avoid the difficult task of managing team and machine while walking on the slippery ice; second, to afford easy facilities for adjusting the scraper in loading, unloading, and moving from one place to another.
The machine is in the form of a box with the bottom and front open, at which opening the snow enters as the machine is drawn forward. The snow thus gathered is carried to any desired point and left in windrows or piles, when the back of the box is raised by the driver, as hereinafter described.
The body is made of wood firmly braced and bolted with iron.
I obtain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a front and side "iew. is a back and side view.
A is a movable fore foot or part to iron runner, to enable the machine to be easily moved over highways or fields; is attached to frame or body by bolts easily removed by turning nuts off when set to work moving snow on ice.
B are colters to cut crust on snow, if any, firmly fastened on square shaft C, which has bearings at It; C, square iron shaft-holding colters B, with bearings at R; D, levers attached to shaft C at each end to adjust the colters B so as to enter the snow just under the crust, lifting and breaking it as the machine moves forward, and attached'to body by bolts in end of lever at any desirable point.
Fig. 2
(No model.)
E is a scraper to gather and retain the snow; is made of wood faced with iron at bottom, hinged at 3, and held in position for working by sliding bolts Fin sockets G; H, a lever, which when forced to stop I draws bolts F from sockets G and releases scraper, when the load of snow immediately stops, and the scraper, being drawn over it, will rise, thus carrying lever J, which is attached to its back, forward to the driver on sea-t K, enabling him to lock it in recess L, or hold it in hand, the scraper being suspended, ready to drop of its own weight, and readjust and lock by the action of the spring-bolts F; M, a spring operating on lever H, which forces bolts F out so as to catch in sockets G when the scraper falls into position for work; N, foot and knee support for driver while operating machine; 0, shafts by which team controls movements of machine.
I am aware that there are various iron-faced snow-scrapers drawn by teams attached by poles, shafts, or traces. I therefore do not claim broadly; but
What I do claim as my invention, and desire to secure by Letters Patent, is-
I. In a snow-scraping machine provided with iron runners, the combination of the fore foot attachment A secured by bolts to the frame orjbox, substantially as described.
2. The crust-cutting colters B on shaft C, supported on bearings at It It, with crank D on ends of shafts C, which are bolted in their ends to any desirable point on box or frame for adjusting the colters Bisubstantially as described.
3. The self-fastening adjustable scraper E, hinged at 3, held in position when at work by sliding bolts F in sockets G, the controllinglever H, the stop I, the seat K, the recess L, to retain lever J, holding scraper suspended while moving or turning, and spring-bolts F, all substantially in combination, as described and set forth.
