Description

slotted to receive the heel of a crosscut-saw. 0 is a screw-collar, sleeved on and fastened to WILLIAM K. STANSBURY,
PATENT QFFIC OF DETROIT, MICHIGAN.
IMPROVEMENT IN CROSSCUT-SAW HANDLES.
Specification forming part of Letters Patent No. 158,537, dated January 5, 1875; application filed July 15, 1874.
To all whom it may concern:
Be it known that I, WILLIAM K. STANs- BURY, of Detroit, in the county of Wayne and State of Michigan, have invented an Improvement in Orosscut-Saw Handles, of which i the following is a specification: l
The object of my invention is to provide a crosscutsaw handle with a simple and efl fective device for securing it to the tangs of saws of varying breadths; and it consists in a slotted rod miveted at its upper end to a washer over the top of the wooden handle, in which the rod rotates freely. Atthe lower end of the handle there is a stationary screw-collar with which engages a cylindrical nut, by partially unscrewing which the saw-tang Will be clamped by it in the slot of rod.
Figure 1 is side elevation of the handle, as attached to the heel or tang of a saw. Fig. 2 is longitudinal transverse section at as at.
In the drawing, A represents a wooden handle, through which is longitudinally inserted the metallic rod B, whose top end is riveted. in a washer, b, which prevents it from being withdrawn from the handle, in which it is free to rotate. The lower part of the rod is square in cross-section, and is-longitudinally the lower end of the handle, which is reduced in diameter to receive it. D is a cylinder, closed at one end and internally screw-threaded to screw onto the collar 0. It has a square opening in its head to slip over the rod B, which thus must turn with it. The screw-threads are preferably cut left-handed, as the motion of the nut D to the right is most natural to the workman when he wishes to clamp the saw. The nut 1) being screwed onto the collar, the heel of the saw is passed through the slot on, when it maybe secured by screwing the nut par tially off the collar, which clamps the saw between the nut and the lower end of the slot.
I hereby disclaim the patent of S. Disston, No. 84,095, November 17, 1868.
'What I claim as my invention, and desire to secure by Letters Patent, is
In combination, the hollowed handle A, fitted with the collar 0 and cylinder-nut D, and the slotted rod B, extending through the handle A and secured by a nut. 12, the several parts constructed and arranged substantially as described and shown.
