GRANVILLE NATHAN MOODY, OF AFTON, LOUISIANA.

PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 724,315, dated. March 31, 1903.

Application filed m 14., 1902.

To all whom it may concern:

Be it known that I, GRANVILLE NATHAN MOODY, of Afton, in the parish of Tensas and State of Louisiana,have in vented certain new and useful Improvements in Plow-Points, of which the following is a specification.

My invention relates to plow-points generally and more specifically to a combined detachable plow-point and share cutting edge formed in one piece in improved conformation, whereby it may readily be detached for renewal, and owing to special means provided for its attachment a more secure fastening being afforded.

The invention consists in special details of construction which will now be described in detail, with the novel features pointed out in the claims.

For a full understanding of my invention reference is had to the accompanying drawings and the letters of reference thereon, forming a part of this specification, and in which-' Figure 1 is a front view illustrating my invention, the view showing my combined cutting edge and point secured to the lower or front edge of an ordinary plowshare. Fig. 2 is a similar view showing my combined cutting edge and point detached and spaced from the lower or front edgeof the plowshare. Fig. 3 is an upper edge view of my combined cutting edge and point, showing the construction thereof; and Fig. 4 shows detail sectional views taken on lines 5c 00 and y 1 looking, respectively, in direction of th arrows 1 and 2.

In carrying out my invention I provide a one-piece cutting edge A and point B,adapted to an ordinary plowshare C and involving peculiar securing means, which will be hereinafter fully described.

In adapting the lower or front edge of an ordinary plowshare to snugly fit my edge and point it is reduced or tapered from a to 11, leaving a shoulder at c and the projecting portion 6.

The construction of the partsj ust described have special advantage in affording snug and secure fastening means, as will appear farther on.

As before stated, my combined edge and point is formed in one piece and its upper Serial no, 115,527. (No model.)

edge recessed or grooved from its outer end,

as from f to g, and cut away from 72 to 't', leaving a shoulderj.

D indicates a thickened portion on the under side'of my point, tapering downwardly from its upper end at the cut-away portion h i, as shown in one detail view. (See Fig. 4..) The thicken ed portion D is recessed,conforming to the pointe of the share 0, and the said point e is provided with a shoulder 76, as shown. (See Fig. 4.)

E indicates a lug or projection on the un- ,point, it is only necessary to employ two rivets, one passing through the perforation in the edge A and the registering perforation in the lug or projection E and the other passing through the upper edge of my point B, the point e, and the thickened portion D on the under side of my point.

With the parts secured together as above I described it is obvious that when a new edge and point become necessary the parts may be detached by simply punching out the two securing-rivets above mentioned.

Many advantages reside in the use of my combined plow cutting edge and point. It can be made and tempered, adapting it to more efficiently withstand protracted use than is possible with simply the sharpened edge and point of a common share. It has advantage not only in its peculiar and improved fastening, but owing to the fact that the resharpening of an old share as done by a.-

smith would cost more than a new edge and point such as invented by me.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a plowshare, of a combined cutting edge and point, means for the said securing-rivets, substantially as de scribed.

2. A one-piece share edge and plow-point having a groove in its rear edge ending with a cut-away portion in rear of the plow-point, and a recess in the under side of the point,

I substantially as shown and described. I

GRANVILLE NATHAN MOODY.
