DETACHABLE SAW-HANDLE.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed December 27, 1904. Serial No. 238,450.

To a/ZZ whom it pea/y concern.-

Be it known that I, JAooB L. SHEETS, a citizen of the United States, residing at Stella, in the county of Cowlitz and State of lVashington, have invented a new and useful Detachable Saw-Handle, of which the following is a specification, reference being had to the drawings which form a part hereof.

Myinvention relates to improvements in detachable saw-handles in which two plates are adapted to be adjusted and secured to a saw-blade.

The object of my invention is to provide a detachable handle for saws which can be ad justed to a saw by introducing the saw-blade between oppositely-located plates, between which the saw-blade is easily and rigidly secured. in position by means of an effectivelyoperating cam-lcver. These objects, as will hereinafter be seen, are accomplished by the device I have discovered, and by its improved construction herein shown I am enabled to place on the market a superior article at a moderate cost, and thus meet the demands of the trade in articles of this character. I attain these objects and other practical advantages by the mechanism, combination, and arrangement of parts illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a portion of a large 'crosscut-saw with my device attached. Fig. 2 is a sectional view on the line A Aof Fig. 4, showing the cam-lever and sawblade between the holding-plates, also the cam-lever released and plates in position to receive the saw-blade. Fig. 3 is a sectional view of my device on the line A A of Fig. 4. Fig. 4 is a side view of a large saw with my device attached at both ends. Fig. 5 is a side view of a small saw with my device attached.

Like numerals and letters refer to like parts in all views.

The oppositely-located pair of body-plates B and 0, Figs. 1, 2, 3, are secured to each other at one end in fixed position either integrally by rivets, as at 6 6, or other means, in such manner as to adapt the plate B to be sprung or moved apart from the plate C at the other end. These plates are formed to extend outwardly toward their free ends at a suitably-diverging angle from each other, so that they will automatically spring apart when released. The plates B and C at their integral ends are formed either with a vertical cylindrical opening 2 or other suitable opening or with fiat surfaces, as in Fig. 5, adapting them, respectively, to receive the cylindrical vertical handpieceE, Fig. 1, as in large saws, or a single hand-piece F, Fig. 5, as in small saws. In the construction shown in Fig. 5 the integral ends of the plates B and C are formed with straight and plane surfaces, and the hand-piece F of small saws is secured to the plates by means of rivets or bolts adapted to pass through suitable openings near the end of the plates and in the part F, which is formed to adapt it to be thus secured to the plates. The body-plate C is provided. with a lug 3, which is riveted and countersunk or otherwise fixedly secured to the plate at a convenient distancefrom its end to allow the saw-blade G to be introduced between the plates to securing position. The lug is also formed and placed at a proper position in an angle to the plate C to adapt it to enter and pass through an oppositely-located opening 4 in the body-plate B, Figs. 1, 2. The lug 3 is formed and adapted to receive the cam-lever D outside of the plate B in operative position. At a suitable place near the end of the lug 3 it is provided with a transverse opening adapted to receive a cam-lever pin 5 and allow its axial movement therein. The body-plate C is also provided with two or more studs 8 8, Figs. 2, 3, near its end at a convenient and suitable distance apart,the same being riveted and countersunk therein or secured by other means, and which studs are adapted to enter and pass through holes near the end of the saw blade G and also to enter oppositclydocated openings 9 9 in the body-plate B, Figs. 1, 2, The saw-blade G is provided with two or more openings near its end adapted to receive the studs 8 8. The body-plate C is provided with two or more openings 9 9, Figs. 1, 2, 3, 4, 5, near its end oppositely located to and adapted to receive the studs 8 8.

The cam-lever D has two cam-shaped ears 7 7, Figs. 1, 2, 4:, 5, which have transverse openings in each adapted to receive the pivot-pin 5, each end of which is countersunk and riveted or otherwise secured within the ears of the cam in rigid position thereto. The cam-lever D and the lug 3 are placed at any convenient and suitable angle or position with reference to the plates and hand-pieces E or F to adapt the lever to be operated and adjusted to a position when closed which shall not interfere with the hand when grasping the hand-pieces, Figs.

IIO

1, 4, 5. When the cam-lever D is thrown open, as shown by the dotted lines in Fig. 2, the plate B is adapted to be sprung or moved apart from the plate C.

It will be seen that when my device having the hand-pieces E or F and constructed as shown is adjusted to a saw-blade the camlever is first released to position shown by the dotted lines in Fig. 2, and the saw-blade G is then introduced and adjusted to looking position between the plates. Its end is placed in contact with the lug 3, the camlever D is closed to the position shown in Figs. 1, 2, 4, 5, which forces the studs 88 through properly-located holes in and near the end of the saw-blade, and thence into the openings 9 9 of the plateB. The same movement of the lever also strongly forces the inner surfaces of the body-plates B and C against the surfaces of the saw-blade G, and the construction of the cam-lever adapts it to quickly, conveniently, and securely lock and retain the plates in the said position when closed. The broad flat-surfaces of the plates and the bearings as to the saw-blade of the lug and the studs in their respective positions adapt my device to be secured to and retain the saw-blade to it in rigid posi tion to operate the saw. The broad construction of the plates in my handle also prevents the saw-blade from bending or buckling. It will be further seen that when the cam-lever is released my device can be very quickly and conveniently detached from one saw-blade to be used upon another. This is accomplished in my device, because the plates are so formed that they are at an an gle which designedly'compels them to automatically spring apart when released from the engagement of the cam-lever. The lever is also formed so that it will perfectly operate upon a plane surface of the plate and requires no shoulders, nuts, Washers, or other auxiliary parts.

Excepting the hand-piece E, my device has no parts which are separate or not fixedly secured to it, and by this arrangement and mechanism, as "shown, there are no parts which may become lost or misplaced in position, but the device is constantly in perfect adjustment and ready for instant use.

A detachable saw-handle having oppositely-located saw-securing plates, integral at one end, free at the other, with studs on one plate adapted to pass through openings in a saw and in the opposite plate, and in particular, provided with a horizontally-operating cam-fastening lever D of suitable form and dimensions pivotally mounted on the outside of the plate B in a lug 3 which is fixedly secured to the inside of the plate C and adapted to freely pass through an opening in the plate B all substantially as described.

In testimony whereof I have subscribed my name hereto in the presence of witnesses.

JACOB L. SHEETS.
