ABSTRACT
A vice has a pair of parallel, work-piece clamping jaw-members, which jaw-members are spaced laterally apart. The first jaw-member is a semi-rigid one, while the second jaw-member is completely slidable as an integral unit, and also allows for the two jaw-elements thereof of which it is comprised to be movable toward and away from each, whereby the second jaw-member may be used separately to hold a workpiece, and may be used in conjunction with the first jaw-member for assisting the first jaw-member in firmly and safely clamping a workpiece in order to provide a more stable holding of the workpiece during the working thereof. The second, floating jaw-member may be adjusted for holding the smaller-diameter portion of a long workpiece, while the fixed jaw-member holds and clamps the larger diameter portion of the same workpiece. The second workpiece may be used alone for holding and clamping workpieces that are more difficult to grip, or the like, and also may be used for holding a tool, or similar article, while the first, semi-rigid jaw-member clamps a workpiece associated with the tool being clamped by the floating jaw-member.
This invention relates to vises, and more particularly has reference to an improved bench vise of the double jaw type.
Heretofore various forms of bench clamps have been devised for special purposes, but so far as I am aware, none have been of general application and embodied the improved features of the present invention. In previous designs of bench clamps, certain forms of special clamp jaw arrangements were provided, but none of the bench type having double jaws for firmly clamping a work piece at four points in the particular manner of this invention are in common and well known use.
It is the object of the present invention to provide an improved bench vise of general application having improved means for firmly clamping or gripping a work piece. Another object is to provide an improved bench vise of the double jaw type wherein two sets of clamping jaws are disposed in rectangularly related relation on a common base. Still another object is to provide an improved bench vise of the double jaw type having embodied therein improved jaw supporting means wherein an article may be extended through an opening in the supporting means and clamped at a point intermediate its ends in an improved manner. Yet another object of this invention is to provide an improved vise sup-port having improved clamping means so arranged that a work piece of elongated form may be arranged in a vertical position in the vise jaws and clamped therein at any point between its ends, the improved vise having a novel arrange ment of clamping jaws whereby the work piece is firmly held in position at four points. These and other objects and advantages of the invention will, however, hereinafter more fully appear in the following description and as more particularly pointed out in the appended claims.
DESCRIPTION
BACKGROUND OF THE INVENTION
The present invention is directed to a device for holding and clamping workpieces, such as bolts, bolt-heads, screws, screw-heads, hex-head bolts, socket-head bolts, button-head bolts, 12-point head bolts, hose-end fittings, tubing of any shape, spark plugs and a host of other mechanical parts, tools, and accessories, so that the workpiece may be worked on. Conventional vices provide one clamping jaw-piece for holding workpieces, which does not provide much flexibility, nor, for certain workpieces, a stable, firm grip thereon while the piece is worked on. The present invention overcomes these disadvantages, and provides a flexible vice that holds the workpiece in a much more stable and safe manner.
SUMMARY OF THE INVENTION
It is the primary objective of the present invention to provide a vice for clamping and holding workpieces that provides a great degree of flexibility while increasing the stability and retention of the workpiece while being worked.
It is a primary objective of the present invention to provide a vice that may be used by itself, or itself be held in a fixed, conventional vice for adapting the fixed vice in order to have the benefits of the vice of the invention.
Toward these and other ends, the vice of the present invention has a pair of parallel, work-piece clamping jaw-members, which jaw-members are spaced laterally apart. The first jaw-member is a semi-rigid one, and has a lower, fixed, V-shaped jaw-element and an upper, slidable jaw-element. The second jaw-member is completely slidable as an integral unit, and also allows for the two jaw-elements thereof of which it is comprised to be movable toward and away from each, whereby the second jaw-member may be used separately to hold a workpiece, and may be used in conjunction with the first jaw-member for assisting the first jaw-member in firmly and safely clamping a workpiece in order to provide a more stable holding of the workpiece during the working thereof. For example, the second, floating jaw-member may be adjusted for holding the smaller-diameter portion of a long workpiece, while the fixed jaw-member holds and clamps the larger diameter portion of the same workpiece. The second workpiece may be used alone for holding and clamping workpieces that are more difficult to grip, or the like, and also may be used for holding a tool, or similar article, while the first, semi-rigid jaw-member clamps a workpiece associated with the tool being clamped by the floating jaw-member. For example, the semi-rigid jaw-member may grip a screw, while the floating one holds a matching screwdriver inserted into the slot of the screw, whereby the tool can assist in manipulating, orienting, holding and/or stabilizing the screw while it is being held by the first semi-rigid jaw-member. The frame of the vice of the invention also provides a stepped, annular surface that assists in the holding of the vice of the invention in a conventional, fixed vice, if desired.
