Specication of Letters Patent.

Application filed September 25, 1920. Serial Nor/12718.

To all whom t may concern Be it known that I, RICHARD MARLOW, a citizen of the United States, residin at Ralph, in the county of Tuscaloosa and btate of Alabama, have invented certain new 'and useful Improvements in Flows; and I do hereby 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.

The present invention relatesv to plows, and aims to provide a plow comprising a novel assemblage of the component parts and a simple construction, whereby the plow can be inexpensively manufactured, and in order that same will be thoroughly efficient yand practical in use.

Another object is the provision of a plow having a point piece which can be adjusted to take up wear and which can also be reversed to increase the life and utility thereof.

A further object is the provision of wings or shares which can be reversed to use both the forward and rear edges thereof and thereby increase they life and utility of such wings or blades.

With the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts hereinafter described and claimed, it being un-, derstood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the improved plow.

Fig. 2 is a bottom view thereof.

Fig. 3 is a vertical section on the line 3 3 of Fig. 1.

The plow kcomprises a frog 6 which can be secured on the stock or standard of any suitable plow beam, and which, as shown, has a downwardly extending lug 7 at its rear end to enter a slot 8 in the stock or standard 9, and a bolt 10 engages through the frog to extend through the slotv 8 for clamping the frog on said stock or standard.

A point piece 11 bears on the frog, longi` tudinally thereof, and its sides are arranged at an angle with one another, the same as the side portions of the frog 6, whereby the piece 11 fits over the ridge of the frog, and said piece has each end pointed, as at 12. A bolt 18 or similar clamping element engages through the piece 11 midway between the ends thereof, and extends downwardly through a longitudinal slot 14E inthe ridge ofthe frog 6, whereby to clamp the piece 11 on the frog, and enable said piece to be adjusted longitudinally. Thus, as the forward end 12 of the iece 11 is worn away, it can be resharpened), and the piece 11 adjusted forwardly to take up forthe wear. Furthermore, by looseninol the bolt 13, the piece 11 can be reversed end for end, to bring the other end thereof forward, and thus double the life of the point of the plow.

The frog 6 is provided adjacent to its forward end with extensions 15 extending toward opposite sides and rearwardly at acute angles with the body of the frog, and diverging rearwardly, and said extensions are for the attachment of the wings or shares 16 which extend in the same directions as said extensions. The wings or blades 16 have the shape of a parallelogram and are reversible end for end. The adj acent end portions of the wings 16 overlap the extensions 15, and the adjacent ends of said wings abut the longitudinal edges of the piece 11. The wings 16 are provided at each end near the obtuse angled corners with bolt holes or apertures 17 for the reception of bolts 18 which extend through the extensions 15, for clamping said wings on said extensions. By removing the bolts 18, the wings 16 can be reversed end for end, whereby to bring the other ends thereof adjacent to the piece 11, thereby bringing the rear edges of the wings forward. Thus, both of the longitudinal edges of thewings can be sharpened, to double the life of said wings i by reversing them when the forward edges thereof become worn beyond further use.

AThe point piece 11 is adjustable between the adj acent ends of the wings 16 when the bolt 13 is loosened and theside edges of the piece 11 in abutting the adjacent ends of the wings 16 will retain said piece in proper position flush with said wings, and the bolts 18 and 18 being flush with the piece 11 and wings 16, respectively, will leave the upper surfaces thereof unobstructed, so as to avoid the accumulation of trash on the plow.

The wings 16 can be of different sizes according to the sweep desired, and in some eases, the wing at one side can be shorter than the other or omitted. y

Having thus described the invention, what is claimed as new is A plow comprising a frog having extensions near its forward end extending toward the opposite sides, said frog having a ridge between said extensions, a point piece bearing on the frog over said ridge, said point piece having its opposite ends pointed and beingadapted to be reversed end for end, a clamping bolt extending through said point piece midway between the ends thereof for Clamping said piece on the frog, the frog having a longitudinal slot at said ridge receiving said bolt, a pair of wings each in the shape of a parallelogram having adjacent ends overlapping said extensions, and bolts for removably clamping the end'portions of said wings on said extensions, said wings having apertures near their opposite ends or the engagement of the last named bolts and the wings being reversible end for end In testimony whereof I have signed my,

name to this specification in the two subscribing witnesses.`
