UNITED STATES I PATENT OFFICE.
JOHN A. OHTSHOLM, OF SAUK CENTRE, MINNESOTA.
SNOW-PLOW.
SPECIFICATION forming part of Letters Patent Ito/2 6,779, dated October 16, 1883.
Application filed February 24. 1883. (X0 model.)
To all whom it may concern.-
Be it known that I, Jno. ALEX CHISI-IOLM,
Centre, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Snow-Flows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to the letters and figures of reference marked This invention relates to improvements in snow-plows or track-clearers for use on railways.
It consists in a mold-board having a slot for the rail in its forward edge and provided with a guide on its under side, the base-plate of said guide being joined immediately to the mold-board at the bottom of the slot, and held away from the mold-board at its rear end, as and for the purposes hereinafter described.
It consists, further, in the combination, with the mold-board, of a guide adapted to run on the rail, and having its forward end hingedimmediately to the mold-board and its rear end adjustable to and from the mold-board, and means for holding the guide at'any suitable distance from the mold-board, as will be described.
. In the drawings, Figure 1 represents a front view of the mold-board placed on the rail. Fig. 2 is a top view, and Fig. 3 is an under side view, of the plow complete; and Fig. 4 is a side view of same, with the mold-board in section. Fig. 5 is a detail view of the guide. Fig. 6 is a detached view, in perspective, of the mold-board and handle and means of connecting same; and Fig. 7 is a cross-section of the handle 011 line 00 m, Fig. 3,.all of which will be described.
A is the mold-board, which is provided in its forward edge with a slot, a, which rests over the rail 2), as shown. This mold-board is formed of'a single thin metal plate cut to provide the straight forward edge, a and it is bent into almost a U shape in cross-section, as shown in Fig. 4c. The slot to is out near the outer end of the edge a, leaving only asufficient portion of the metal to provide the point a which clears the snow from along the outer side of the rail,
as will beunderstood on reference to the drawings. \Vhen placed on the rail, the edge a will be at approximately right angles to the rail, and the body of the mold-board will rest at an angle to the rail, with its rear end, a, considerably behind the edge a, so that the snow" gathered by the front portion of the moldboard will readily pass'off at its rear end as it is pushed forward in the operation of the device.
G is the guide,'consisting of the base-plate 0, having its sides turned down to provide flanges c, which rest 011 opposite sides of the rail. The forward end of the plate 0 is hinged to the mold-board A at the base or bottom of the slot a, as shown in Fig. 3, and it'extends back in line with the slot (6 and the direction of motion of the device; and it has the plate 0 turned up from its rear edge and eonstructedw ith the slot c, through which projects the head of clamping-screw 0*, which turns in a threaded opening in lug 0", which extends down from the under side of tlie mold-board, so that the rear end of the guide may be set nearer the mold-board or farther off from same, as may be desired.
d d are staples secured on the under side of the mold-board. The staple d is secured well under the mold-board and in advance of the staple d, which is secured on the bend or at the point of greatest curvature of the same, and, being arranged at an angle to the line of curvature of the n1old-board, it is made higher on one side than the other, as shown in Fig. 6.
e is the handle, having its forward end curved on its upper side to correspond to the curvature of the mold-board A, and inserted in the staples (l d, where it may, when so desired, be secured by bolts or screws, or in other suitable manner. The curve on the upper side of the handle 0 extends back beyond the staple d, and the force exerted against the said handle is directed, therefore, against a considerable portion of themold-board, greatly reducing the liability of the same to be bent. as when force is exerted against a small area. The curved portion of the handle is made V-shaped in crosssection, as shown in Fig. 7, to correspond to the shape of the staple d.
3y having the guide fixed immediately to the the mold-board may be thrown up ordown atits rear end, to adapt it to snows ofv different depths, and the handles will be set correspond ingly higher or lower, as desired, by the operator. t1 therefore prefer the latter construction.
My device is intended, primarily, for use as a hand implement for operation by section hands or laborers employed on the roads. It may, however, have its handle or staff made fast to or be otherwise connected with a locomotive or other moving truck, so as to remove the snow as the said locomotive or truck moves forward.
Having thus described my invention, whatI claim, and desire to secure by Letters Patent, 1s 25 1. In asnow-p1ow, the combination, with the moldboard having the rail slot in its forward edge, of the rail-guide having its front edge secured immediately to the mold-board at the base of the rail-slot, and havingits rear end exo tended under and held off from the said moldboard, substantially as set forth.
2. In a snow-plow, the combination, with the mold-board, of the rail-guide having its front end hinged immediately to the front edge of 35 the mold-board, and means whereby the rear edge of said rail-guide may be adjusted to and from the mold-board, substantially as set forth.
In testimony whereof I afiix my signature in presence of two witnesses.
