QUICK-ACTING WOODWORKING-VISE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed July 10, 1909. Serial No. 506,874.

To all whom it may concern:

Be it known that I, lVAL'rER Y. MnN'rzeR, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Quick-Acting lVoodworking-Vises; and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in quick acting woodworking Vises, and its object is to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims.

My invention consists essentially of a fixed jaw having a plate adapted to be attached to a bench, a stirrup beneath the plate, a half nut mounted in the stirrup, a movable jaw, parallel guide rods rigidly attached thereto, a rotative screw having threads adapted to engage the half nut, and a pivoted yoke in which the screw and rods are slidable; and in various features of combination and arrangement, as will more fully appear by reference to the accompanying drawing, in which: A

Figure l is a longitudinal vertical section of a device embodying my invention taken on the line 11 of Fig. 4;; Fig. 2 a portion of Fig. l with the parts adjusted to detach the screw from the nut; Fig. 3 a transverse section of the device on the line 3-3 of Fig. 1; and, Fig. 4: an inverted plan view of the device detached from the bench.

Like numbers refer to like parts in all of the figures.

1 represents the top of a woodworking bench; 2 a fixed jaw attached thereto by means of a horizontally disposed plate 2 extending beneath the said top and integral with the jaw 2.

3 represents the movable jaw in which are rigidly inserted parallel guide rods l spaced apart and extending at the respective sides of a screw 5, rotatively mounted in said jaw.

8 is a yoke beneath the plate 2 and pivoted to the same near the rear thereof as at 9. The screw 5 is longitudinally movable in said yoke, and the guide rods 4 also extend through tubular side portions 8 of the yoke, and are slidable therein. Extending downward from the plate 2 near the front thereof, surrounding the screw 5 and spaced apart therefrom, is a stirrup 7 in which is secured a half-nut 6 by means of a lug 6*. This stirrup supports the screw, the guide rods, and the yoke in a horizontal position when the screw is engaged with the half nut, and by lifting the movable jaw 3, the yoke will turn on the pivots 9 and the screw be raised clear of the half nut, whereupon the screw and guide rods will slide freely within the yoke to quickly adjust the vise to different dimensions of work.

The screw 5 and half nut 6 are made with buttressed threads, the engaging and working surfaces of which are at right angles to the axis of the screw, whereby the screw has no tendency to slip out of engagement with the half nut when the vise is tightened on the work.

\Vhat I claim is 1. A quick acting vise, comprising a fixed jaw, a stirrup below the same, a half nut in the stirrup, a movable jaw, a screw rotative in the movable j aw and laterally engaging the half nut, and a pivoted yoke in which the screw is slidable.

2. A quick acting vise, comprising a fixed jaw and amov. ble jaw, guide rods fixed in the movable jaw and spaced apart, a screw between the guide rods and rotative in the movable jaw, a stirrup surrounding the screw and spaced apart therefrom, a half nut in the stirrup laterally engaged by the screw and supporting the same, a yoke pivoted at the rear and vertically movable at the front, in which yoke the guide rods and screw are slidable longitudinally.

3. A quick acting-vise, comprising a fixed jaw, a horizontally disposed plate integral therewith, a movable jaw, guide rods spaced apart and fixed in the movable jaw, a screw between the guide rods and rotative in the movable jaw, a stirrup on the plate supporting the screw, a half nut in the stirrup beneath the screw, and a yoke pivoted to the plate at the rear of the stirrup and having tubular side portions in which the guide rods are slidable.

4. A quick acting vise, comprising a fixed jaw having an integral plate to attach to the under side of a bench top, a movable jaw opposite the fixed jaw and extended below the plane of the plate, parallel guide rods spaced apart and fixed in the movable jaw,

a screw between said rods and rotatiire in the transverse portions in which the screw is movable jaw, a stirrup depending near the slidable. 10 front of the plate and supporting the screw, In testimony whereof I afiix my signature a half nut in the stirrup and laterally enin presence of two witnesses.

5 gaged by the screw, a yoke pivoted to the WALTER Y. MENTZER.

rear of the plate extending forward there- Witnesses: from and having tubular side portions in H. O. VAN ANTWERP,

which the rods are slidable, and also having GEORGIANA CHACE.
