Specification of Letters Patent. Patented Aug; 20,191g,

Application filed January 25, 1918. Serial No. 213,688.

To all whom it may concern:

Be it known that l, 'VOLNEY W. MASON, Jr.. a citizen of the United States, and a resident of Kingston, in the county of Ulster and State of New York, have invented a new and Improved Snow-Plow, of which the following a full, clear, and exact description.

My invention relates to snow plows, and an object thereof is to provide a simple, inexpensive, efficient, and collapsible plow.

Another object of the invention is to provide a snow plow of the V type, the angularity of which may be varied to plow paths of different widths.

A further object of the invention is to provide a snow plow which can be dragged or pushed, with means for steering in push; ing or dragging the same.

A still further object of the invention is to'provide a plow of the manual type with weights and handle so related as to prevent the attacking or front end from digging "into the ground and the rear end from rising when plowing the snow by dragging or pushing the plow.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction. combination and arrangement of parts as her in fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a plow of the manual type embodying my invention;

Fig. 2, a top plan view;

Fig. 3. a section on line 33. Fig. 2:

Fig. 4, a section on line 44. Fig. 2; and

Fig. 5 is an elevation of the plow in col lapsed position ready for transportation or storage.

Referring to the drawings. 5 5 are mold boards connected at one end by hinges 6 so as to form a V. the angularity of which 1 may be varied. Each of the mold boards preferably widens to the rear, to prevent the packed snow from passing over the top edge when the snow is deep. Each board is provided with a brace 7 hinged to the inner face of the mold board and adapted to extend toward the face of the other mold board, the two braces being retained against one another by a bracket 8 in which the braces 7 are free to slide. A set screw 9 is provided in the bracket to lock the braces in the bracket and thereby prevent a relative movement of the two mold boards. By means of these braces and bracket the width of the V formed by the mold boards may be varied. The braces are preferably provided near the rear end of the mold boards so as to better resist the pressure which tends to collapse the plow.

Each of the mold boards 5' has an opening substantially midway between the hinged end and the hinged brace, the two openings alining to receive a transverse bar 10 of a: handle 11, the transverse bar being free to turn in the alining openings so that it can be swung either toward the apex of the V, as indicated in dotted lines inFigs.

' 1 and 2, or maintained against the bracket 8 as shown in full lines in said figures. The transverse bar 10 is generally introduced first into one of the openings at an angle and then pushed through the other and the handle 11 brought into the central plane of the plow on the bracket 8 wherein a suitable notch 12 is provided in aneXtension 13 of the bracket. This notch 12 when engaging the handle 11 prevents lateral movement of said 'handle and therefore, if pressure is applied tothe handle bar 14 of the handle 11 the plow can be guided 'while pushed, for there will be two points at which the steering is effected; one. the engagement of the handle bar with the notch 12: and the other, the engagement of the transverse bar 10 with the mold board. The same efiect takes place when the handle is swung to the front to drag the plow: in which case the engagement of the apex with the handle proper isone of the points which facilitates the steering, the other point'being the engagement of the transverse bar 10 with the mold boards;

To prevent the front of the plow from digging into the ground when pushed or dragged, I provide a weight 15 at the rear end of each of the mold boards. As shown,

these weights are in the shape of a cast block bolted to the mold board: but they may be in the shape of a receptacle for loose weight or to accommodate a concrete block. These weights being located in the rear prevent the rear of the plow from rising when the plow moves through the snow; otherportion which the boards when the plow connected to form a V, a brace between the boards, a handle pivotally connected .to the boards formed by the boards so as to engage either the brace or the apex, and a wing for each of the boards, each of jaw for engaging-the upper edge of the board and a slot for engaging the handle engages the corresponding board whereby the Wings can-be adjusted longitudinally ofthe board.

In a snow forming a V, a brace between the mold boards, a handle having a transverse bar revolubly mounted in the boards so that the handle can be supported by the brace or the apex of the V, and a wing for each of the boards adapted to extend upwardly and rearwardly of each board, said wing having a jaw for resiliently engaging the board at the upper edge, said wing having also a slot for engaging the transverse bar of the handle andwhereby the wings may be adjusted a lunged to'form a V, a

a weight at the free end of each longitudinally of the boards.

6. In a snow plow, a pair of mold boards hinged to form a V, a brace for adjusting the width of the V, weights at the rear ends of the. boards, and a handle secured pivotally to the boards to be disposed above the brace or the apex of the Vv to prevent the rising of the rear or the front end of the plow respectively when pulling or pushing the plow by the handle.

In a snow plow, a pair of mold boards, means hinging the boards to form a V which can be folded to bring the outer surfaces in contact, foldable brace members associated with the boards, including means for preventing the collapsing of the V formed by is in use, a'handle detachably and pivotally secured to the boards to besupported by the apex formed by the boards or by the brace members when the plow is in use. v
