Application filed March 19, 1915. Serial No. 15AM,

To all whom it may concern: i,

Be it known that 'I, HUG T. TOY, a citizencofthe United States, residing at Sidney, in the county of Shelby and btate 5 of Ohio, have invented certainnew and useful Improvements in Plows; and I do hereby it declare the following to be 'a' full,

clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make anduse the same.

walks, street gutters and jthe like, and my object is to provide a device which will impart a rolling motion to the snow so as to properly remove the same from the side walk. a

A further objectis to provide means for increasing or decreasing the width of the path made by the plow.

A further object is to provide means for holding the plow against lateral skidding movement.

A further ObJQCt is to so construct parts of the plow that it can be readily moved onto the side walk without the driver having to dismount; a

Qther-objects and advantages will be here inafter set' forth and more particularly pointed out in the'accompanying specification.

In the accompanying drawings which are madea part of this application, Figure 1 is a perspective view of the plow, and Fig. 2 is a'similar view showing portions ofthe -plow removed 1 a r Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 indicates the beam or runner of my improved plow which is preferably c0nstructed of I-beam formation, the forward end 2 of the beam being bent upwardly to form a runner the curved face 8 of the runner having a shoe or wear plate, 4 attached thereto toprevent wear directly on the beam, said shoe also extending below the horizontal portion of the beam so as to normally support the beam slightly above the surface of the side walk. Attached to the free end of the end section 2, is a clevis 5 of the usual or any preferred formation, to which the draft animal is attached for Specification of LetterSPatent.

My invention relates to new and useful improvements in plows and more particu; larlytothat class adapted tobe used for 15 removing snow and the like from side.

drawing the plow. The rear portion of the beam 1 'is also provided with an upwardly curved section 6, said curvature be- 1ng sufiicient to raise the rear end 7 of the beam a distance above the surface over which the beam is traveling, and immediately below the elevated section 7 and attached thereto is a channel shaped guide member 8, the depending edges 9 thereof being preferably pointed, so that they will firmly engage the surface over which they aretraveling and hold the rear end of the beam against lateral skidding movement.

A bracket 10 is attached to the beam 1, one end of the bracket engaging the upper inclined end 2 and the opposite end the upper face of the beam proper and extend ing verticallythrough the horizontal arms of the bracket and into an opening in the beam 1 is a rod 11 with which pivotally engage hinge straps 12 of the mold boards or scraper 13, said straps being fixed to the forward ends of the moldboards.

The forward ends of the mold boards are substantially flat and they have their extreme forward ends preferably slightly curved inwardly so as to present a rounded surface to the snow or other particles being removed, and in order to cause the snow to be rolled laterally as the plow is dragged therethrough, said moldboards are constructed with a concavo-convex formation, the curvature gradually increasing from the forward to the rear ends of the moldboards,

and in view of said curvature, the snow,

when contacted by the moldboard will travel up the curved faces thereof and more readily free itself from the moldboards than would be the case were the moldboards left perfectly flat.

Hingedly attached to the inner faces of the moldboards 13 adjacent their rear ends are space bars 14 which are substantially L-shaped in cross section and in inverted relation to each other, the ends thereof be ing attached to the moldboards by means of straps 15, while the inner ends of said space bars are overlapped with each other and introduced through a socket 16 carried by the end 7 of the beam 1, the horizontal portions of said space bars being provided with a plurality of registering openings 17 to receive a pin 18, said pin extending clownwardly through an aperture 19 in the socket 16 and through said registering openings thereby holding the moldboards 13 in proper spaced relation, and by providing-a plurality of the openings 17, said moldboards may be set at various angles to increase or decrease the path made by the:

plow.

Fastened tothe inner faces of-the moldboards 13 are curved feet 20, which serve to limit the depth of the moldboards 13 and prevent the same from sagg ng at their outer ends, whereby they would tend to. engage the surface of the sidewalks or street over which the plow is being propelled. The plow is also provided with a suitable seat 21 which is mounted upon a standard 22 carried by the beam 1, a brace 23 being attached to the standard adjacent its connection with theseat and to the upper surface tion when the draft animal is started forwardly to drag the plow through the snow. In. view of the curvature of the moldboards,

as the plow travels forwardly, the snow will be gathered and directed outwardly from the central portion of the plow, thus clearing to the width at which the moldboards are set, and if it is desired to form a narrower or wider path, the pin 18 is removed,

the moldboards adjusted and the pin again returned through the registering openings. If a gutter is to be cleaned or if the space to be cleaned is of such nature that but one moldboard can be used, the rod 11 and pin 18 are removed from their respective positions and one of the moldboards disengaged from the plow, after which the pins are returned to their respective positions to hold the remaining moldboard in its. proper adjust-ed position.

As shown, this device is constructed entirely of metal and for such reason, it is rendered extremely strong and durable, and in view of the few parts can be very cheaply constructed. It will likewise be seen that by providing the guide member at the rear end of the plow, the plow will be normally held against lateral skidding movement, and by providing the adjusting means, paths of varying widths may be formed.

Copies of this patent may be obtained for And it will likewise be seen that by constructing the mold'boards so that the snow,

etc., will pass from off the same in a substantially rolling formation, the draft of the plow will be materially lessened, and the plow rendered more thorough in itso p oration as the snow will not be inclined to hang and bank against the faces of the moldboards. v v

WhatI claim is'f'."

1. Asriow plow, comprising a beam of substantially I-beam formation having an upwardly extending forward end and an elevated rear end, a shoe attached to the forward portion of said beam, a channel shaped guide member attached tosaid elevated. rear end, a pairof moldboards hav-- ing curved surfaces] hingedly secured at their forward endsto theforward portion of said I-beam, and means at the rear ends. adjust the angle of of said moldboards to the moldboards. p p

2. A snow plow, comprising a beam having an upwardly. extending forward end and anelevated rear end, a shoe secured. to the upwardly extending forward end mold boards pivoted to said beam, means to regulate the width ofsaid mold boards, and a channel shaped guide member attached to the elevated rear "portion of the beam, the

depending portions of said guide member having sharp edges whereby the rear end of the plow will be held against lateral.

skidding movement."
