ROD MOUNTIN VISE G A FIXED JAW AND AN ADJUSTABLY FULCRUMED PIVOTABLE JAW Filed May 17, 1955 United States Patent VISE ROD MOUNTING A FIXED JAW AND AN ADJUSTABLY FULCRUMED PIVOTABLE JAW Arthur C. Pothier, Westbrook, Maine Application May 17, 1955, Serial No. 508,901

1 Claim. (Cl. 8123) This invention relates to vises and particularly to vises whose jaws are adapted to grip work that cannot be securely held by jaws whose work-engaging portions are parallel.

While vises in accordance with the invention are adapted for general use, they are particularly well suited for supporting a television or radio chassis or that of a record player where it is essential to provide an adequate grip without objectionably marring or otherwise damaging the gripped structure.

The general objective of the invention is to provide a vise ensuring that such work may be properly held. This objective is attained by providing at least one of the jaws with at least one and preferably two work-engaging members adjustable relative thereto and to each other to enable work to be gripped that could not be securely held by parallel work-engaging surfaces.

One of the jaws is fixed while the other one is preferably pivoted to swing between engaged and disengaged positions relative to the other jaw. An operating member is threaded through one jaw for engagement with the other thus to furnish means for pivotally effecting their clamping relationship and the operating member is preferably carried by the pivoted jaw and so formed and disposed that its weight is effective to urge it towards its disengaged position.

In the accompanying drawings, there is shown an illustrative embodiment of the invention from which these and other of its objectives, novel features, and advantages will be readily apparent. In the drawings:

Fig. 1 is a view of a vise in accordance with the invention as seen from its upper end,

Figs. 2 and 3 are, respectively, side and end views thereof,

Fig. 4 is a fragmentary vertical cross section through the pivot portion of a pivotable jaw,

Fig. 5 is a fragmentary horizontal cross section through both jaws illustrating their relationship with a clamped workpiece, and

Fig. 6 is a fragmentary side elevation of the jaws illustrating their disengaged relationship.

At 10, there is indicated a bench shown as having a socket 11 dimensioned to receive an extremity 12 of a support 13 provided with a bench-engaging flange 14. Slidably supported by the support 13 is a mount 15 adapted to be locked thereto as by the setscrew 16 and having a sleeve portion 17 slidably receiving a spindle 18 but provided with a spindle-locking setscrew 19.

A fixed jaw 20 is located at one end of the spindle 18. A second jaw 21 has a vertically elongated aperture 22 dimensioned to freely receive the spindle 18 and to enable the jaw 21 to tilt forwardly and rearwardly to a predetermined extent. A bore 23 transversely intersects the aperture 22 and has an enlarged, threaded portion 24 to receive a threaded hub 25 of a pivot 26. The spindle 18 has a plurality of axially spaced transverse bores 27 each dimensioned to receive the pivot 26 thus to enable the jaw 21 to be pivotally mounted in any one of several positions relative to the jaw 20.

Threaded through the lower part of the jaw 21 is a member 28 engageable with the proximate face of the jaw 20. The member 28 is dimensioned and disposed so that its weight is operative to urge the jaw 21 to swing into disengaged relationship to the jaw 20. When the member 28 is threaded to advance it relative to the jaw 29, it is operative to swing the upper part of the jaw 21 towards the jaw 20.

While a vise in accordance with the invention is adapted to handle any type of work, it is particularly well suited for holding the chassis of a television or radio set or that of a record player. Such a chassis is suggested at 29 and it will be readily appreciated that with work of that or like nature, it is of real advantage to have the vise jaws normally spaced apart.

Such work is also illustrative of another problem and that is the difficulty of gripping work where the gripping zones of the opposite faces of the work are not parallel thus making it difficult to securely hold the work, at least without the risk of marring it. In accordance with the invention, one of the vise jaws, preferably the jaw 21, is provided with transversely spaced bores (usually two) extending between its front and rear faces and threaded to receive screw elements 30 which establish readily replaceable teeth that may be quickly and easily adjusted to effect an accurate and secure support of the work.

From the foregoing, it will be appreciated that a vise in accordance with the invention is well adapted to meet a wide range of work-supporting conditions.

What I therefore claim and desire to secure by Letters Patent is:

In a vise, a jaw-supporting rod of substantially uniform cross section, a pair of workpiece gripping jaws mounted on said rod, one of the jaws being rigidly fixed to the rod and the other jaw being provided with an opening substantially larger than the cross-sectional area of the rod, said other jaw being movable along the support to various positions and pivotable to said support at a selected one of a plurality of positions so as to pivot between engaged and disengaged positions relative to the fixed jaw, said jaw-supporting rod having a plurality of axially spaced bores which define said plurality of positions, said pivotable jaw having a threaded bore transversely intersecting the opening therein, and a pivot pin having an enlarged threaded portion fitting the threaded bore and a reduced portion fitting the selected one of the axially spaced bores, and a threaded jaw-actuating member extending through the pivotable jaw and engageable with the fixed jaw to move the jaws into gripping relation.
