OBADIAH SEELY, OF SYRAOUSE, NEW YORK, ASSIGNOR TO E. C. STEARNS & CO., OF SAME PLACE.

SAW-VISE.

SPECIFICATION forming part of Letters Patent No. 339,020, dated March 30. 1986- Application filed January 27, 1886. Serial No. 189,890.

To all whom it may concern:

Be it known that I, @naman SEELY, of the city of Syracuse, in the county of Onondaga and State of N ew York7 have invented a new and useful Improvement in Saw-Vises, of

which the following is a specification.

This invention relates to an improvement in that class of vises which are employed for holding saws during the operation of sharpenio ing the same, and has for its object to provide suitable means for adjusting the vise to the most desirable position for light and to prevent vibrations of t-he saw under the action of the iile, thereby avoiding` noise, lessening the lai5 bor of sharpening the saw, and reducing the wear of the files.

My invention consists to that end of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure lis afront elevation of a saw-vise provided with my improvements. Fig. 2 is a sectional elevation at right angles t0 Fig. l. Figs. 3 and 4 are horizontal sections in lines :t a:V and y y, 2 5 Fig. 2, respectively. Fig. 5 is a front elevation of the lower part of the vise,showing the camlever released. Fig. 6. is a side elevation of the washer of the adjusting device.

Like letters of reference refer to like parts 3o in the several iigures.

A represents the supportingclamp of the vise, which is fastened toa workbench or other stationary support,A,by a clampingscrew, a.

B represents the stationary jaw of the vise 3 5 provided with a downwardly-extending arm, b, which is attached to the clamp A by a ball-and-socket joint. The arm bis bifurcated at its lower end and terminates in two dependinglugs,b.

4o c c represent two arms,which rise from the lower bifurcated end of the arm b, and which are arranged at a short distance in front of the arm Z), to form a space for the reception of a saw between the arms c and the arm b. The

upper ends of the arms c are arranged at a suitable distance below the stationary jaw B, and receive a horizontal pivot-bolt, d, to which the movable jaw D is pivoted.

rIhe ball-and-socket joint by which the (No model.)

stationary jaw of the vise is attached to the 5o clamp A is constructed in the following manner:

e represents an opening formed in the arm b, and Eis ascrew-bolt passing through the opening e. llhe bolt E is provided with a rounded head, e', which is seated in the openinge, on one side of the arm b, so that the bolt can assume positions at various angles in the Opening e.

F represents a spherical washer arranged on the opposite side of the arm b, and pr0- vided with a lip, j', which enters a recess or notch, f', in the arm b, so that the washer moves with the arm of the vise and forms a knuckle for adjusting the vise on the clamp. 6 5

G represents a spherical socket formed on the upper end of the clamp A, and receiving the spherical washer or knuckle F. The screwbolt E passes through an opening in the clamp, which opening is somewhat larger than the diameter of the screwbolt, so that the latter has a certain play in said opening.

His a screw-nut applied to the bolt E, on the rear side of the socket G, and provided with a handle or thumbpiece, so that the nut can be readily tightened and released.

Upon releasing the nut H the vise can be adj usted on the clamp A, so that the jaws are either horizontal or inclined in one or the other direction, as may be necessary, in order to obtain the most desirable position for light or convenience in filing.

The movable jaw D is provided with two downwardlyextending arms,l,which are pivoted to the bolt d, between the arms c ofthe 85 stationary jaw, which latter are preferably connected below the pivot d and above their lower ends by a cross-piece, i.

J represents a cam, which is pivoted to the lugs b,and which bears against the lower ends ofthe arms I, for closing the movable jaw D. The cam J is provided with a lever or handle, J for operating it, which lever is curved upwardly, as represented in Figs. l and 2, so as to be out or' the way when the movable jaw is closed.

K represents an auxiliary movable jaw, which is arranged at a short distance below the jaw D, and provided with a'downwardlyf extending arm, k, lwhich'is pivoted to the b/lt d, between the arms I of the jaw D.- The lower end of the arm k rests against an eccentric projection or raised cam, Z, formed on the cam J, so that by turning the cam J both jaws Dand K are closed successively.YV f

M represents a spring, which is secu red to the arm k of the auxiliary jaw by a rivet, m, and which bears with its free end against a crosspiece, m, at the lower end of the stationary arm b, so as to open the jaw K when the cam J is released. The auxiliary jaw K bears against the movable clamping-jaw D by means of an interposed spring, n, so that both jaws K and D are opened by the spring M when the cam J is released.

Upon tightening the cam J, which is effected by turning the handle Jl upwardly, the lower ends of the arms I. and K are simultaneously swung outwardly, thereby swinging the jaws D and K toward the stationary jaw B. After the clamping-j aw D has been closed against the saw O (placed between the jaws B and D) by the cam J, the auxiliary jaw K is still further tightened by the raised cam l, thereby pressing the jaw K against the saw below the clamping jaws B and D. This causes the saw to be spru ng and to be tightly held against the clampingjaws B and D, whereby the saw is prevented from vibrating during the operation of filing. By holding the saw rigidly in the vise in this :manner the disagreeable noise usually attending the operation of sharpening asaw is avoided, the labor of filing is lessened, and the wear of the files reduced.

In order to insure a close fit of the auxiliary jaw against the saw said jaw may be provided with a rubber cushion, p, seated in a recess formed in the face of the jaw.

I claim as my inventionl. The combination, with the support A, provided with a spherical socket, G, of a vise provided with a spherical knuckle, F, seated in said socket, a screw-bolt, E, connecting the krickle of the vise with the socket G, and a screw-nut, H, applied to the bolt E, substantially as set forth.

2. The combination, with the support A, provided with a spherical socket, G, of a vise provided with a separate spherical washer, F, which is attached to the vise and seated in the socket G, a screwdoolt, E, and nut H, substantially as set forth. y

3. The combination, with the clamping-jaws B and D, of an auxiliary jaw, K, which bears against the clamped'article andA springs or detleets the same, substantially as set forth.

4. The combination, with the stationary clamping-jaw B, of the pivoted clamping-jaw D, and a pivoted auxiliary jaw, K, adapted to bear against the clamped article below the jaws vB and D, substantially as set forth.

5. The combination, with the stationary clamping-jaw B, provided with a depending arm, b, having ascending arms c, ofthe clamping-jaw D and the auxiliary jaw K, both pivoted to the arms c, substantially as set forth.

6. The combination, with the stationary clamping-jaw B, provided with a depending arm, b, of the pivoted clamping-jaw D, provided with arms I, the pivoted auxiliary jaw K, provided with an arm, k and the cam J, which closes the jaw D,and which is provided with araised portion, Z, whereby the auxiliary jaw K is closed, substantially as set forth.

7. The combination, with the stationary clamping-jaw' B, provided with a depending arm, b, of the pivoted clamping-jaw D, provided with arrns I, the pivoted auxiliary jaw K, provided with an arm, k, the cam-lever J J spring M, attached to the jaw K, and a spring, n, interposed between the jaws D and K, substantially as set forth.

Witness my hand this 9th day of January, 1886.
