VISE.

SPECIFICATION forming part of Letters Patent No. 319,743, dated June 9, 1885.

Application filed August 4, 1884. (No model.)

To all whom it may concern: Be it known that I, STEPHEN 0. PARKER,

of Meriden, in the county of New Haven and said drawings constitute part of this specificaa tion, and represent, in-

Figure 1, a sectional side View of the vise; Fig. 2, a top view of the base or socket, the vise removed; Figs. 3 and 4, modifications.

This invention relates to an improvement in that class of bench -vises which are constructed so as to be rotated in a plane with the bench, that the position of the jaws may be changed according to the work requiredfor the vise.

The object of my invention is the construction of a swivel-vise so that it may be secured directly to the top of the bench, in substantially the usual manner for attaching Vises which are not swiveled; and the invention consists in the construction hereinafter described,and particularly recited in the claims.

A represents the base of the socket, which is constructed with ears or flanges B, by which it may be secured to the bench. It is best recessed upon its under side, as shown. On its upper surface is a circular flange, C, which forms a corresponding circular recess or socket on the top of the base; D, the base of the stationary part of the vise, constructed upon its under side with a downwardly-projecting trunnion, E, corresponding to the recess within the flange G on the socket, and so as to set therein as in a socket. Through the center of the socket a screw, F, is introduced into the bottom of the stationary part of thevise, the head of the screw standing in the recess in the under side of the base, and so as to take a bearing upon the base and hold the vise in the socket, but yet so as to permit its rotation. At some point in the flange 0 a clamping-screw, G, is introduced in a position radial to the axis on which the vise turns, and so as to bear against the .trunnion, and so that when the screw is turned hard against the trunnion E it will clamp the vise in the socket sufficient to hold it to any position to which it may be adjusted. Preferably I apply a shoe, H, between the end of the screw and the periphery of the trunnion E, and in some cases diametrically opposite the clamping-screw I set a block, I, corresponding" to the shoe, so that the trunnion will be clamped between the shoe H and the block I. The bearing-faces of both the shoe and the block may be roughened or serrated to make a firm bearing against the periphery of the trunnion. The socket is secured to the bench by screws through the ears B, in the usual manner of securing a non-swiveling vise.

The entire vise is therefore above the plane of the top of the bench and avoids cutting away or defacing the surface of the bench, as is necessary in vises in which the swiveling device extends into or through the bench. By

loosening the screw G the vise may be turned and set to any desired angle, and there clamped by turning the screw G.

Instead of the screw G as a clamping device, other known equivalents may be employed-as, for illustration, acam, L, as seen 7 5 in Fig. 3. I therefore do not wish to be understood as limiting my invention to any particular clamping device.

Instead of constructing the socket with a recess and the trunnion on the vise, this order '80 clamping device to secure the vise in the socket at various positions, and therefore do not claim, broadly, such construction.

I claim- 1. The combination of the base A, constructed with the circular flange C, forming a 0 circular recess on the top of the base, the stationary part of the vise constructed with a trunnion, E, corresponding to said recess, the screw F, centrally through the base into the body of the vise, the clamping-screw G, ar- 5 ranged radially through the flange O, and

shoe Hfietweentheend of the screw and the I peripher'yofiithe"ti'unnions, substantially as described; 4

2. The combination of the base A, con- 5 structed for attachment to'the top of the bench,

' and with'tlie circular" flange G upon its upper surface, forming a circular reoess'therein,v the stationary part of the vise constructed with a trunnion to set intosaid recess, tl m clamping screw; G, shjoe H, and block I, substantially IO as and for the purpose described.
