Specification of Letters Patent.

Patented Dec. 8, 191 1.

To all whom it may concern:

Be it known that I, ROBERT J. CowAN, a citizen of the United States, residing at Dalworth, in the county of Dallas and State of Texas, have invented a new and useful Plow, of which the following is a specification.

This invention relates to plows, its primary object being to provide a plow which can be converted readily from one type to another, there being improved means where by the points and moldboards of the plow can be connected to the main structure which structure includes a runner, handle carrying means, and connections between the runner and a beam.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure 1 is a bottom plan view of a plow embodying the present improvements. Fig. 2 is a perspective view of the main structure with the plow points and moldboards removed. Fig. 3 is a front elevation of the plow. Fig. 4 is an enlarged section on line A-B Fig. 1.

Referring to the figures by characters of reference 1 designates the plow beam, the same being preferably formed integral with a standard 2 provided at its lower end with a foot 3. Brackets 1 are bolted to the sides of the standard 2 near the upper end thereof and extend laterally. Extending past the lower end of the standard is a runner 5 having its front end pointed, as shown at 6. Detachably secured to the sides of the runner are side plates 7 which fit snugly against the runner and extend to the upper end thereof and also up close to the point 6. Each of these side plates 7 has a laterally extending inclined wing 8 at its front end. The foot 3 ofthe standard 2 is detachably secured to the runner and the side plates by bolts 9 or the like extending transversely through all of them. Forwardly diverging braces 10 are secured to the side plates 7 back of the foot 3 and are front ends, with ears 11.

In some types of plows, such as utilize two moldboards, the share 12 of the plow is placed on the wings 8 and bolted thereto, sald share bearing upon the front end 6 of the runner and projecting therebeyond, as shown in Fig. 1. The moldboards 13 are arranged back of the share and are likewise bolted upon the wings 8, these moldboards also being attached to the brackets 1. The ears 11 at the ends of the braces 10 are bolted to the lower faces of the point 6 and moldboards 13 and thus cooperate with the wings S to hold the moldboards snugly against the back edge of the point.

Brackets 14 are bolted or otherwise secured to the lower surfaces of the mold boards and attached to these brackets are the upwardly and rearwardly extending handles 15. Forwardly converging braces 16 extend from these handles and are attached to the rear portions of the beam 1, said braces being secured by means of a bolt 17 or the like extending through an opening 18 in the beam.

Extending transversely through the rear portion of the runner and through the rear portions of the side plates 7 is a bolt 19 on which a colter blade 20 is pivotally mounted. This blade has an arcuate series of apertures 21 any one of which is adapted to receive a fastening bolt 22 extending transversely through the parts 5 and 7 whereby the colter blade is held against swinging movement after having been adjusted angularly. Bolt 19 also engages the lower end of a standard 23 having apertures 24 therein.

Should it be desired to convert the plow into a turning plow, such as shown for example in Fig. 5, a share 25 of proper form is secured upon one of the ears 11 and wings 8 and the plate 7 at the other side of the runner is removed as is also the brace 10 and the bracket 4: arranged at the same side as the removed plate. A moldboard 26 is then disposed back of the share 25 and secured to the wing 8, car 11, and remaining bracket 4. One of the handles 15 is attached to the brackets 14 at the back of the moldboard 26 while the other handle is brought down and secured to the standard 23. In this form of plow the runner constitutes a landside.

Obviously other forms of points and provided, at their moldboards may be combined with the structure shown in Fig. 2.

What is claimed is In a plow structure, a straight runner having its front end pointed, the upper edge of the said end being inclined down- Wardly and forwardly and constituting a bearing for the meeting edges of opposed plow shares, said point being adapted to extend toward the front extremity of the shares, plates detachably secured to the opposite sides of the runner, Wings outstanding from the inclined upper edge of the pointed end ofthe runner, said Wings being adapted to be secured to the shares and to opposed moldboards, braces secured Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

Washington, D. C.
