PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 542,981, dated July 16, 1895.

Application filed September 21, 1894:. Serial No. 523,725. (No model.)

To all whom it may concern;

Be it known that I, REUBEN JONES, a citizen of the United States of America, and a resident of Kirkwood, in the county of De Kalli and State of Georgia, have made a certain new and useful Plow-Point; 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 artto which it appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to shares or points for plows. The object of the invention is to provide means for holding the same rigid upon the standard or foot of the plow, and, further, to relieve the heel-bolt of part of the strain thereon, thereby insuring the point reelevation of the back side of a point.

mainin g rigidly in place, never workin g loose, and preventing danger of breaking the heelbolt.

The invention is illustrated in the accompanying drawings, in which- Figure lis a perspective view of a plowpoint, showing the back thereof. Fig. 2 is an Fig. 3 is a sectionaldetail, showing the manner of turning back the metal inone of its forms. Fig. 4 is a cross-section of the standard, showthe side-bars thereof. Fig. is a modification of the device, showing the metal punched from the hole bent back upon the main body of the plow-point.

In the figures, like reference-marks in dicating corresponding parts in all the views, l is a plow-point, blade, or share which may obviously be of any form desired, and may be either cast or wrought metal. The usual hole 2 for the heel-bolt 3 is punched in the upper end of the said point, the metal, however,being not cut along one side in the form of the device shown' in the drawings, but merely cut along three sides and turned backwardly, as

ployed for the purpose.

seen in the drawings, suitable tools being em- Two forms of construction are shown. One (shown in Fig. 3) is simply allowed to roll back from the hole 2 as the punch enters, while the otherform (shown in Fig. 5) is afterward pressed down dat upon the body-metal of the point. The object and function of this lug 4, so formed, is to enter between the side pieces of the standard 5 and lit same closely, thereby preventing the plowpoint from moving laterally with relation to said standard, no matter what the shape of the ex treme end or other part of the plow-point may be or in what direction the strain of operation is applied.v This obviates the necessity of tightening the heel-bolt so closely, which is now sometimes done by hammering saine with an ax even, in a vain eiort to get sufficient compression to-hold the plow-point rigid through any considerableperiod of working same.

In heavy plows it is preferable to further strengthen the engagement of the point and standard. This is done by splitting the metal above the hole 2 and turning back lips 6 therefrom, which lie against the respective sides of the standard, contacting Vwith inner side of each side piece of the same.

Having th us described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A plow-point consisting of the blade-proper, having a hole for the heel-bolt punched therein, a lug on the back side of said blade below the hole, and metal being slit from said hole upward and lips turned back therefrom, said lugs and lips being adapted to iit between the side-pieces of the standard, substantially as and for the purpose specified.

In testimony whereof I hereunto aliix my signature in presence of two witnesses.

REUBEN JONES.
