1 Claim. (Cl. 81-33) My present invention relates to tools and more particularly to adjustable-position bench swivel-Vises.

The principal object of my invention is to produce an improved bench vise.

Another object is to produce an improved bench vise having a supporting pedestal capable of a 360 degree swivel movement about a vertical axis, and having a jawcarrying superstructure arcuately slidable on the supporting pedestal to provide a 90 degree adjustable movement of the clamping axis of the vise jaws about a horizontal axis.

Other objects and novel features of the vise will be more apparent as the description of the construction and operation of it progresses. I

In the drawings illustrating the preferred embodiment of the invention:

nited States Patent Fig. 1 is a side elevation of the vise and shows the clamping axis of the jaws extending horizontally;

Fig. 2 is a top plan View;

Fig. 3 is a side elevation corresponding to Figure 1, but shows the clamping axis of the jaws adjusted to a vertical position;

Fig. 4 is a front elevation of the vise in the normal position, as seen from the left in Fig. l;

Fig. 5 is a side elevation of the base and swivel saddle carriage upon which the upper portion of the vise operates;

Fig. 6 is a typical vertical, central cross section of the vise in the maximum elevated position shown in Fig. 3, portions being shown in elevation;

Fig. 7 is a fragmentary cross section taken on the line 7-7 of Fig. 1, portions of which are shown in elevation.

Fig. 8 is a detail view, partly in cross section, of a pinion shaft, and

Fig. 9 is a fragmentary cross section of a modified vise, and shows a modification of the means for clamping the jaw-carrying superstructure to the supporting pedestal.

Referring more in detail to the drawings 10 indicates a fixed base having solidly aflixed hold-down lugs 11 for securement to a bench or other fixture. The under side of the fixed base 10 is annularly recessed to receive a disc member 12 capable of 360 degree rotation in the recessed fixed-base 10.

On the top surface of the fixed base 10 is mounted a swivel-base disc-portion 13 having a shouldered bottom-face 14 rotably mounted in a flanged portion 15 of the fixed base 10. The shouldered bottom-face of the swivel portion 13 is fixed to the disc 12 by means of the stud posts 16 the threaded ends of which are threadably engaged in tapped holes in the disc 12. The threaded portion of the posts 16 are loose through the swivel base 13 so that they can easily be turned to act as binding studs that lock the swivel base portion 13 firmly to the fixed base 10 by clamping the disc 12 against the fixed flange portion 15.

It will thus be seen that the swivel base portion 13 2,750,824 Patented June 19, 1956 may be rotated 360 degrees around the fixed base 10 and be locked to the fixed base at any point desired.

On the top face of the swivel portion 13, and being a part thereof is a central pedestal portion 17, rectangular in horizontal cross section, and comprising an upper saddle portion 18, which is extended at one end so that it over-hangs the pedestal portion 17. This saddle portion 18 is provided with a cylindrically concave upper surface, and projecting from each longitudinal side is a curved rib 20 in the form of a section of an annulus.

On the concave upper side of the saddle portion 18 is located a similarly arcuate rack 21. It will be observed that the arcuate rack 21 and the curved ribs 20 have the same axis of curvature and thus provide a curved guide upon which is mounted an arcuately slidable vise jaw superstructure having parallel side walls 22 and 23. These walls have cylindrically convex lower edges (as viewed in Fig. 1) the inner sides of the walls being provided with confronting grooves 22a and 23a which lie parallel to said convex lower edges. These curved grooves 22a, 23a have the same axes of curvature as the ribs 20 on the saddle 18 and, when mutually engaged, provide arcuate slideways for the jaw-carrying superstructure, and permit a degree adjustment of the clamping axis of work- engaging jaws 24 and 25. This upper structure is further provided with an internal pinion shaft 26 journalled through aligned transverse bores in the sides 22 and 23, the pinion teeth 27 engaging with the teeth of the rack 21 so that the turning of the pinion shaft 26 rotatably positions the sides 22 and 23 on the arcuate slideways.

The pinion shaft 26 is flatted at 28 on the end protruding from the side 22. A forked lever 29 is pivoted at 30 to'the flatted sides 28 of the pinion shaft 26. The inner edges 31 of the lever 29 are curved for wiping contact with a boss on the side 22. The upper part of the curved edge 31 of each fork of the lever is eccentric so that when the lever is tipped up, as shown in dot-anddash lines in Fig. 4, the sides 22 and 23 are compressed, thus jamming the pinion and frictionally tightening the side walls 22 and 23 on the saddle 18, thereby locking the jaws in any desired position.

When the lever 29 is in the positions shown in Figs. 1, 2, 3 and 4, it acts as a crank to rotate the pinion shaft 26 moving it along the rack 21 thereby rotating the jaw structure.

Upper forward portions of the side walls 22, 23 are rigidly connected by the jaw 25 and by an anvil-forming plate 32. An intermediate portion of the side walls is bridged by a plate 33 (see Fig. 6) parallelly spaced from the anvil plate 32, so as to form a tubular slide way having flat interior surfaces 34 (see Fig. 7). A tubular slide 35, rectangular in cross section, engages the flat surfaces 34 and at one end is rigidly joined to a base portion of the jaw 24. The slide 35 has an internal bore 36 which houses a substantial portion of an elongate sleeve-nut 37. The latter projects beyond the rear end of the slide 35, and this projecting portion has a transverse bore that receives a pin 38 secured in aligned apertures in the side walls 22, 23. Threadedly engaged in the nut 37 is the jaw-tightening screw 39. The forward portion 40 of the screw 93 is journalled in the base portion of the jaw 24. The extreme forward end of the screw portion 40 is provided with an annular groove 41. A split washer 42 is recessed in the extreme front of the base of the jaw portion 24 and engages around the annular groove 41. A plate 43 is secured by screws 44 to the base portion of the jaw 24. An enlarged and shouldered portion 45 of the screw 39 is provided with a transverse bore which receives a slidable cross-handle 46 for turning said screw.

"ice

In operation, the vise may be rotated 360 degrees about a vertical axis, and the clamping axis of the jaw structure may be rotated 90 degrees about a horizontal axis from the normal position shown in Fig. 1 to the vertical position shown in Figs. 3 and 6, or to any angle within such range of movement. The latter adjustment is made by turning the crank lever 29, when it is in a cranking position and, by tipping the handle 29 to the position shown in Fig, 4 in dot-and-dash lines, the jaw structure will be securely locked in position.

In Fig. 9 is shown an alternative means for locking the clamping axis of the jaw structure in adjusted position. In this modification, the upper side of the saddle 18 is not provided with rack teeth. A partially threaded stud 50 is mounted in aligned bores in the side walls 22' and 23, and has a smooth portion that makes a force fit with the bore in the side wall 23, while the threaded end loosely extends through the bore in the side Wall 22. A hand-wheel 51 is threaded onto the stud 50. The jaw superstructure is rotated on the saddle portion 18 to any angle desired and the handwheel 51 is tightened thereby frictionally jamming the side portions 22 and 23 on the saddle portion 18. The sides 22 and 23 only have to be compressed a matter of a few thousandths of an inch to efiect this condition.

It is to be understood that I may vary the shape and proportions and use patentable equivalent structure in my invention within wide latitude while remaining within the scope of the appended claims.

Having thus described my invention in detail what I claim as new is:

An improved bench swivel-vise comprising in combination, a swivel base mounted on and interlocked with a fixed base portion and means for locking said bases together, a saddle portion fixed to said swivel portion, an upstanding central portion of said saddle portion comprising a cylindrically concave and upwardly facing toothed rack having arcuate slideways located on its opposite sides, said rack and said slideways having a common horizontal axis of curvature, a vise-jaw superstructure having parallel side walls, said side walls having arcuate guideways complementary to said slideways and arcuately slidable thereon for adjustment of said superstructure about said horizontal axis of curvature, a pinion shaft journaled through said side walls and having central pinion teeth meshing the teeth of said concave rack, a pivoted crank handle pivoted to said pinion shaft for rotating said pinion shaft in order to adjust said superstructure about said axis of curvature, said handle having a cam portion for locking said superstructure to said rack in any adjusted position, said superstructure having a raised vise-jaw-portion, a slid able jaw having a tubular guide portion which is square in cross section, said square tubular guide portion having its longitudinal axis normally extending horizontally, said square tubular. guide portion being slidable in a slideway of square cross section, said square slideway being located in the superstructure between said side walls and below said raised vise-jaw portion, the square tubular portion of the slidable jaw merging into a solid front portion which is provided with a bore having its longitudinal axis coinciding with the longitudinal axis of said square tubular portion, a vise-operating screw journaled in said bore in said solid front portion, a sleeve nut threadedly engaged over the rear portion of said screw member and having its extreme rear end portion fixed between said side walls by means of a pin passing through said nut portion and the side walls, a forward end of said concave rack extending beyond said upstanding central portion and constituting a stop member for said superstructure, said stop member being engaged by the solid front portion of said slidable jaw when said longitudinal axis of said square tubular portion reaches its normal horizontal position.
