ROBERT J. LAVELL, OF CINCINNATI, ()HIO.
Application filed October 10, 1923. Serial No. 667,685.
To all whom it may concern:
Be it known that I, ROBERT J. LAVELL, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State (i'f Ohio, have invented certain new and useful Improvements in Scoop Snowplows, of which the following is a specification.
This invention relates to scoop snow plows and it consists in the novel features hereinafter described and claimed.
An object of the invention is to provide a scoop plow especially adapted to be used for removing snow from sidewalks, streets or roadways and car tracks.
A further object of the invention is to provide an implement or device of the character stated and intended to be used for the purposes mentioned, and which is of simple and "durable structure and can be easily and quickly manipulated or handledin the operation of breaking or cutting the snow preparatory to lifting and removing the same from the surface upon which it has accumulated.
With these objects in view, the scoop plow comprises a blade formed from a single blank of sheet metal and shaped up to provide at its forward portion a scraping edge disposed at a right angle to the median dimension of the blade and provided in a plane extending along the median dimension of the blade with an upwardly and rearwardly inclined incising, splitting or cutting edge, which is disposed at a right angle to the said scraping edge.
Before it is formed up into final shape the blank of which the blade is composed isin the shape of'a polygon and when shaped it is in the general form of an incomplete pyramid which is square at its base in plan. This drawing action to which the sheet of metal is subjected in the shaping of the blade brings two of the forward edges of the blank into alignment with each other and constitutes the scraping edge above referred to and the upper edge portion of the blank is drawn in or contracted laterally whereby the intermediate area of the blank is bulged or humped forwardly thereby providing the incismg edge referred to.
Frame bars are attached to the upper and lower portions of the finally shaped blade and a handle member may be detachably applied to the frame bars.
In the accompanying drawings Figure 1 is a perspective view of the scoop plow.
Figure 2 is a top plan view of the same.
Figure 3 is a longitudinal sectional view of the same.
Figure l is a plan view of the blank from which the blade is formed.
Figure 5 is a perspective view of one of the frame bars.
As illustrated in Figure 4: of the drawing, the blank 1 from which the blade is formed is of polygonal configuration having an upper straight edge 2, side straight edges 3 and lower or forward straight edges 4 which are disposed at an obtuse angle with relation to each other and which are separated from each other at their inner ends by an incision 5 made in the lower forward portion of the blank 1 and along the median dimension thereof. The edges 3-3 are disposed at an acute angle with relation to each other.
When the blank is formed up into the blade the edges 3-3 are drawn parallel to each other as best shown in Figure 2 of the drawing whereby the intermediate area of the blank 1 is upwardly or forwardly bulged or humped and which is rovided with a relatively sharp incising e ge 6 lying in a plane parallel with the vertical planes in which the edges 33 lie and which is disposed along the mediate dimension of the blade. At the same time the edges 4.-4 are drawn into alignment with each other and are disposed at a right angle to the edges 6 and 33 as best indicated in Figure 2 of the drawing. The forward portions of the blank are then folded back along the dotted lines 7--7 (see Figure 4;) whereby a continuous and transversely rounded scraping edge is provided at the forward portion of the finally shaped blade. A
A frame bar 8 is disposed in the fold provided at the forward edge portion of the blade and may be secured therein by rivets or other suitable securing devices and the said bar is provided with upwardly and rearwardly d1sposed arm portions 9 carrying at their upper ends a socket 10 which is disposed along the median dimension of the blade and under the incising edge 6 but disposed in a plane lying above the plane in which the side edges 33 lie.
A frame bar 11 is provided at its ends with angularly disposed lug portions 12 which are riveted or otherwise secured to the side portions of the blade at the upper edge 2 thereof and the said bar 11 is disposed transversely across the median dimension of the blade and is provided with an eye 13 which is in alignment with the cavity of the socket 10. A handle member 14 may be passed through the eye 13 and its lower end inserted in the socket 10 thus completing the assembly and structure of the scoop plow.
,VVhen in usethe handle member 1% is held by the operator who directs the blade toward the layer of snow whereby the forward scraping edge is inserted under the snow and between the .snow and the surface of the street or track. At the same time the incising edge cuts into the layer of snow and divides the same into blocks or portions which lodge upon the side portions of the blade at the opposite sides of the said incising edge. The blocks or portions of snow thus broken or cut from the layer of snow are cast to one side whereby the street surface. or track is cleared of the snow deposited thereon.
lVhen not in use it is apparent that the handle member may be removed from the blade portion whereby the parts may be brought together in compact form, occupying but little space in storage or during transportation.
From the foregoing description taken in conjunction with the accompanying drawings it will be seen that a scoop snow plow of simple and durable structure is provided and that the same may be easily and conveniently used for removing the fallen snow from streets, roadways, car tracks and the like.
Having described the invention, what is claimed, is
A scoop plow comprising a blade formed from a blank of sheet metal having a straight horizontal lower forward edge disposed at a right angle to the median dimension of the blade and provided with an in termediate' bulged area having an iircising edge disposed at a right angle to the forward edge and extending at an upward and rearward inclination from a point directly over the latten ahorizontal transverse frame bar attached to the forward edge portion of the blade and having a socket which is disposed und'er the bulged area of the latter, a second horizontal transverse'frame bar attached to the upper portion of the blade and bridging the bulged area. thereof and having an eye which is disposed in alignment with the cavity of the socket and a handle member insertable through the eye and into the socket.
In testimony whereof I aflix my signature.
ROBERT J. LAVELL.
