IMPRCVEMENT IN HANDLES FOR CROSSCU'T-SAWS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, WILLIAM CLEMsoN, of Middletown, in the count-y of Orange, in the State of New York, have invented anew and improved Mode of Attaching Handles to Crosscut-Saws; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters ot reference marked thereon.

My invention consists of' the combination of the devices used by which the handle is tirrnly attached to the saw.

To enable others skilled in the art to make and use my invention, I will describe its construction and operation.

In the drawings- Figure 1 represents a section of a s aw with the handle attached; Y

Figure 2 is a cross-section of same;

Figure 3 is a view of the upper end of the ferrule on the handle; and

Figure 4 is a section of the inclined slotted clampblock.

A represents a part of the blade of a common crosscut-saw.

E is a looped or slotted screw-shank, having the saw A inserted in the slot.

D is an inclined slotted clamp-block, having a hole in its centre, through which shank E freely passes, and is made higher on one side than on the other, to tit the taper ofthe saw, and has a concave slot, ,on its inclined end, which tits closely'upon the back of the saw.

C is a fel-rule, with a solidend, c, in which is a female screw, and into which the screw on the end of the `shank enters.

The slot a in clamp-block D is made concave, to insure a close fit ou the back of the saw, at its outer contact with the saw, as seen in red lilies, as seen Vin dotted lines, in lig. l o

The ribs d, on the inside of the ferrule, prevent the handle from turning in, and without turning the nut c on the screw-shank.

Then the ferrule C is placed on the handle B, the screw-shank is passed through clamp-block D, and is then screwed into the nut-part of the ferrule C, the clamp-block D turnedv so that the inclined side fits the taper of the back of the saw, which is inserted iu the loop-part of the shank, and the slot in the block embraces the back of the saw, as 'seen in iig. 1, and the handle B is turned down upon the screw-shank E, the block is forced upon the saw, and the handle is firmly xed to the saw; and 4by only turning the handle in the opposite direction, the handle is released, and can be taken from the saw.

This construction and arrangement of devices make an attachment that is cheap, easily operated, and that can be depended upon for security, as Well as durability, and not likely to get ont of order, and admits of a considerable variation 0f width iu saw-blades, and allows/the handle to always be at right angles with the saw.

I am aware that slotted screw-Shanks, inserted in handles, have been used forat-taching handles to saws; such slotted screw-shanks or hooks I do not claim. ,Nor do I claim for the ribs on the inside of the ferrule, as such ribs are old and in use; but having described my invention,

W hat I claim, and desire to secure by Letters Patcnt, is

The combination of the slotted screw-shank-E, inclined slotted block I), ferrule C, and handle B, when constructed and arranged to operate together, in the manner and for the purpose described.

XVM. CLEMSON.
