TO ALL WHOM IT MAY oononruv;

Be it knoivn that I, EBEN M. BOYNTON, of Grand Rapids, in the county of Kent, and State of Michigan, have .invented certain new and useful Improvements in Saw-Handle Fastenings or Tangs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever theyoecur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in constructing, in a novel manner, a detachable handle-sockct or.tang for saws.

Figure 1 is a side elevation of a portion of a saw, with my improved tang applied.

Figure 2 is a bottom plan View of the tang detached.

Figure 3 a top plan viewfof the same.

Figure 4 an edge view of the slotted bolt by which the socket is secured to the saw.

It is Well known to those experienced in the business of using cross-cut saws, that it frequently happens, in sawing oil logs, especially where the log happens to lie on uneven ground, the upper side of the cut made by the saw is forced together or closed, in such a manner as to prevent the raising of the saw up out of the cut, and

jvhcn this happens there is no means of removing the saw, except by raising the log, so as to open the cut, on

by removing the handle and its sockets at one end of the saw, and-then drawing the latter through cndwise.

As these sockets or tangs are usually riveted fast to the saw, it is impossible toremove them without great difficulty and delay. To obviate these diflicultics a variety of plans have been devised for so securing the socket "that it can be detached from the saw, but as yet these devices have not fully answered the desired purpose.

The object of my invention is td so construct a socket that it can be secured firmly and rigidly to the saw,

and at the same time to permit of its being easily and quickly detached and replaced.

I construct a socket, A, with an arm, B, projecting laterally from one side, .as represented in figs. 1, 2, and 3, the socket A being intended to receive the ordinary wooden handle used with such saws. In ,the under side of the arm or projection 13, a longitudinal groove, 92, is formed,-as represented in fig. 2, and as indicated by dotted lines in fig. 1, this groove being intended to fit upon the upper edge of the saw-blade when the socket is applied thereto, as represented in fig. 1, the groove also extending down along the side of the socket A, as shown by the dotted lines. I then provide a bolt, D, having a slit, e, in it, of suflicient length to slip over the end of the saw, the upper end of the bolt D extending up through a hole, 0, in the arm B, and having a thumb-nut, E, applied thereto, as represented in fig. 1. If desired, a notch may be cut in the under edge of the saw-blade C, to receive the lower portion of the bolt I) where it passes around the blade, and prevent it from slipping thereon.

Themanner of applying the device to the saw is fullyshown in fig. 1. Itwill be seen that, when the socket is applied, as there represented, the groove in the under side of the arm 13 prevents any lateral movement, and when the thumb-screw is tightened up the whole is held tightlyin place, and at the same time, by simply loosening the nut, the loop or bolt D, with the socket, can be quickly'detached from the saw, and can be as quickly replaced.

By making the socket of malleable cast iron, it can be cast ready for use, and thus furnished very cheaply. If desired, the bolt and nut may also be made of similar material, though these I prefer to make of wrought iron.

Having thus described my invention, what I claim, is y y The detachable saw-tang, consisting of the socket A, with the arm B, having the groove 12 formed in its under side, in combination with the slotted bolt D and the thumb-nut E, substantially as described.
