IMPROVEMENTJN SAW-HANDLES.

Specification forming part of Letters Patent 0. 149,781, dated April 1 I, 1874; application filed March 25, 1874.

1 To all whom 2t may concern:

Be it known that we, JOHN MURRAY, of Oonshohocken, Montgomery. county, Pennsylvania, and WILLIAM S. WrNrnRBo'rroM, of Philadel iihia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Saw- Handles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othtachments.

The nature of our invention consists in the peculiar and novel construction and combination of parts, as hereinafter fully set forth.

In the accompanying drawing is illustrated a saw with our improvements applied, A be ing the handle and B the blade thereof. The handle A is formed with slots, to a, and the blade has two holes punched in it for the passage of binding-screws G G. D D are metal cleats, fastened to the handle A by means of ordinary wood-screws, d d. The screws G 0 pass through thesecleats, the cleats D having a smooth hole, while the cleats D have threaded openings, so that on turning said screwsthe outer end of the cleats will be.

drawn toward each other, firmly binding the wood handle between them and clamping it down upon the saw-blade, which is thereby very securely held.

The advantages of the foregoing construction are briefly as follows: Owing to the provisionof the metal cleats, the binding-screws take a firmer and more secure hold, and may be placed at the very edge of the handle without any danger of splitting it. It is obviously an advantage to place the screws as near the edge as possible, for thereby greater clamping power is obtained. The slots are more easily made than holes, and not only avoid all danger of the handles splitting after it has been applied, as is sometimes caused by the bearing of a screw in a hole, but enables the person. applying the handle to obtain access readily to the holes punched in the blade for the passage of the screws. Another very great advantage of this method of fastening (which may be applied to all kinds of saws, compass saws, back saws, butcher saws, kitchen-saws, hand-saws, and saw knives) is, that when a handle becomes'broken itnia be so easily removed and a new one applied. To do this a plain new handle is taken. The position of the holes in the blade are marked and slots sawed in the handle to register therewith. The cleats are then fastened on so as to bring the holes for the passage'of the binding-screws O in a line with the slots at a, the screws d d entering the wood at any suitable position. The blade is then placed in the usual slot at, the binding-screws inserted and turned, clamping the blade firmly. It is obvi ous that the cleats D D may be made of one piece each, and that the design may be greatly varied to obtain any desired degree of ornamentation.

\Vhat we claim as our invention is-- The handle A, having the slots a a open at one end, in combination with the cleats D D and screws 0 C d d, substantially as shown and described. y

In testimony that we claim the foregoing we have hereunto set our hands this 20th day of March, 1874.

JOHN MURRAY. WILLIAM S. WINTERBOTTOM.
