IMPROVEMENT 1N PLOUG'HS.

TO ALL WHOM'IT 'MAY CONCERN:

Beit known that I, LEWIS GIBBS, of Gantoiuin the county of Stark, and State .of Ohio, have invented certain new and useful Improvements in Ploughs'; and I do rhereby declare the following to be a full, clear, and exact description of the same, reference being had tothe accompanying drawings. making a part of this specieation, in Which- Figure 1 represents a. view of the plough from the land-side, and

Figures 2, 3, and 4 represent respectively, and Onan enlarged vscale, aside, top, and horizontal section of the @levis and point of the plough-beam to which it is united. l I l Similar letters of reference where they occur in the separate figures denote like parts in all cases.

Letters Patent of the United States were granted to my assignees on the 12th March, 1867, for an improvement in ploughs, in which many of the features of the `present invention may be found, and do not propose to again describe these features, but to point out the difference between them and thepresent invention. A Y

Inthe plough above referred to the bar on the land-side is secured to the share near the point by a dovetail on top, in which position it is liable to wear away by use. In the present invention unite the bar A to the share B by a dove-tail, a, underneath, so that the wear upon the share does not Vinjuricnsly affect the `joint or point of union. This mode of uniting the bar and share, as well as that heretofore patented, as above stated, avoids the necessity of Welding,- these pieeestogtlh'er at that point, and makes either piece removable'and replaceable without removing or replacing both, and in steel or cast-iron ploughs is a very decided saving and advantage. In other respects the plough maybe like that patented to my assignees, as above mentioned.

Another part of my invention consists in a cast' clevis, made in two parts, and so constructed that when applied to the beam it shall clasp the beam by a dove-tail connection, and be held rmly thereto by a bolt passing through the clevis and beam. C and C represent the two sections of the clevis,febeinfT the dividing line or jointbetween them. The end of the plonghbcam D is shaped as shown in thesection, tig. 4, and the cheeks d of the Vclevis are hollowed out so as to lie snugly against this' out portion of the beam, andmay lap over the top and bottom of the beam more orless, as seen in iig. 3, so as to he flush with the sidesoi' the beam. When the two-sections C Care laid against the sides of the beam so prepared to receive them, a bolt, e, is passed through and through to hold them` together and to the beam, the strain on the clevis in Vdrawing lthe plough thus coming upon the dove-tail formed on the end of the beam. The clevis hooker ringf is held in either of the holcs'l 2 3' byabclt or key passing through the forward ends of the elcvis. ,The hole for the bolt c is represented at Having thus fully described my invention, what Iclairn therein as new, and desire -to secure by Letters Patent, is

described.

2. I also claim a clevis made in two parts, with dove-tail recesses cast therein, so as to fit a dove-tail or shoulder formed on the end of ,the beam, and united thereto by a bolt or key, substantially as herein described and represented. r

LEWIS GIBBS.
