IMPROVEMENT IN SAW-HANDLES.

I Specification forming part of Letters Patent No. 154,000-, dated August 11, 1874; applization liled May 4, 1874.

To all whom it may concern:

Beit known ythat I, ELIAs G. ATKINs, of Indianapolis, in the county of Marion and State of Indiana, have invented a certain Improvement in Saw-Handles, ot' which the following is a speciiication:

This invention relates to that class of crosscut-saw handles composed of a clamping-rod, screw-threaded at one end, to turn in a nut in the wooden portion ot' the handle, and provided at its other end with either a hook or a slotvto embrace the blade, a wooden handle, and a loose ferrule, notched at its lower end to receive the top edge ot' the blade.

My improvement consists in providing the feriule interiorly with a transverse horizontal plate, either in the shape of a wedged-in washer, or of a web cast on it, it heilig', in either case, perforated centrally, to permit the screw-threaded portion of the clamping-rod to pass up through it, but not the slotted end thereof', thus preventing the accidental loss of the ferrule by slipping down over the clamping-rod. A bearing-ring is also secured to the handle, to compensate for the Wear as the handle is'turned on the ferrule in clamping the'saw, and is an improvement upon the patent granted to me June 10, 1873, No. 139,756.

Figure lis a vertical section transverse to the saw. Fig. 2 is an elevation partly in section.

The same letters of reference Vare used in both gures in the designation of identical parts.

A refers to the wooden handle, having a central bore in its lower end for the reception ofthe screw-threaded end of the clamping slotted-rod B, working in a nut,'C, secured in the handle in the ordinary manner. The lower end of the handle is somewhat reduced, and provided with a fixed bearing-ring, D, driven onto it up against the shoulder, The ferrule E tits loosely over the reduced endof the handle, and is flaring in outline, as clearly shown, projecting a considerable distance downward from the handle. Its bottom edge is suitably notched to receive the top edge of the saw, and is circular like the remainder. It is made hollow from end to end, but has an interior plate, F, which maybe either a separate washer wedged in, as shown, or cast solid With the remainder. Its central aperture is onlyr large enough to let the screwthreaded end of the rod B pass through for the purpose stated.

In clamping the handle to a saw, its bearing-ring is drawn closely against the top edge of the loose ferrule, and takes up all the wear, saving the wooden handle.

`What I claim as my invention, and desire to secure by Letters Patent. is

1. The loose ferrule E, provided with a perforated horizontal lock-plate, F, substantially as and for the purpose specitied.

2. The combination of the wooden handle A, bearing-ring D, and loose `ferrule E, substantially as and for the purpose specified.

In testimony whereof I have signed Iny name to this specicat-ion in the presence of two subscribing witnesses.

ELIAS C. ATKINS.
