United States Patent JAR VISE Vernon E. Holmen, Cameron, Wis.

Application August 17, 1953, Serial No. 374,510

1 Claim. (Cl. 813.32)

The invention relates to jar vises and more particularly to vises or holders for glass jars used in preserving fruits, vegetables, and other food products.

The main object of the invention is to provide certain improvements over the jar vise of my prior U. 5. Patent No. 2,569,239, dated September 25, 1951, whereby the support for the jaws is simplified and improved, and this support and jaws are of a more sanitary form so that they can be more readily cleaned and the jaws with their actuator be easily removed from their support.

The invention further consists in the several features hereinafter set forth and more particularly defined by claim at the conclusion hereof.

In the drawings:

Fig. 1 is a plan view of a jar vise embodying the invention, parts being broken away and parts being shown in section;

Fig. 2 is a side elevation view of the jar vise, parts being broken away and parts being shown in section;

Fig. 3 is a detailed vertical sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a detailed vertical sectional view taken on the line 44 of Fig. 2.

Referring to the drawings, the vise includes a U-shaped round bar 5 forming a jaw support and guide and adapted to be secured to a side table, wall, or other upright by a channel hanger bracket 6 secured to said upright and engaged by a tongue 7 depending from the yoke portion of said bar.

Individual jaw members 8 and 9 and in the case of large diameter jars an intermediate support 10 are slidably mounted on the bar 5.

The jaw member 8 is of sheet metal formed to provide a base portion 11 and angled jaw portions 12, each of which are faced with a relatively thick vertically ribbed facing 13 of rubber or other suitable material. The base portion 11 has depending tubular flanges 14 for sliding engagement with the spaced legs of the bar 5. A rubber faced metal shelf 15 welded or otherwise suitably secured to the lower edges of the jaw portions 12 extends between them. The outer end of the base has a depending flange 16 apertured to loosely receive an actuating rod 17.

The support 10 of sheet metal has tubular flanges 18, similar to the flanges 14, for sliding engagement on the legs of the bar 5 and a rubber facing 19 similar to the jaw facing 13.

The jaw member 9, of sheet metal, is formed to provide a base portion 20 and angled jaw portions 21, each of which are faced with a rubber facing 22 similar to the facing 13. The base 20 has depending tubular flanges 23 for sliding engagement with the spaced legs of the bar 5. A rubber faced metal shelf 24 welded or otherwise suitably secured to the lower edges of the jaw por- 2,732,740 Patented Jan. 31, 1956 tions 21 extends between them and has an apertured flange 25 depending from its front edge with a nut 26 welded thereto.

A spring 27 interposed between the flanges 16 and 25 normally serves to hold the jaws in separated or open position.

The actuating rod 17 has its inner end 28 threaded to engage the nut 26, and its outer end extending beyond the flange 16 carries a rivet 29 forming a pivot for a manually operable carn lever 30 engageable with a metal washer 31 abutting the flange 16, said lever also acting as a hand hold to turn the rod 17 relative to the nut 26 to adjust the spacing of the jaw members 8 and 9 relative to each other.

In using the vise, a jar I is placed in upright position on the shelves 15 and 24 of the opened jaw members and upon the auxiliary shelf or support 10 if this is used. The lever 30 is then turned to turn the rod 17 relative to the nut 26 to move the jaw members 8 and 9 inwardly toward each other until the rubber facings 13 and 22 of the jaws 12 and 21 engage the sides of the jar. The final clamping pressure between the jaw members and the jar is then elfected by swinging the lever 30 from its dotted line position shown in Fig. 2 to its full line position. The amount of squeeze of the jaws is regulated by the initial squeeze of the jaws on the jar through the turning of the rod 28 relative to the nut 26. To hold the jaw parts against removal from their support, one of the jaw members may carry a set screw 32 at one or each side having a thumb head 33 for turning it into engagement with one of the legs of the bar 5, and this lock may also serve to initially position the jaw members on the support. The jaw members 8 and 9 and the support 10 may be easily slipped off of the bar 5 for cleaning.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claim.

What I claim as my invention is:

In a jar vise, the combination of a support having spaced bar portions, a pair of jaw members having base portions provided with flanges slidably mounted on said bar portions and having jaw portions provided with jar engaging facings of yieldable material, each base portion provided with an apertured depending flange, the apertured flange for one of said jaw members having a threaded part, the apertured flange of the other jaw member being unthreaded and depending from the rear portion of its base, an actuating rod extending loosely through the unthreaded flange and having a threaded portion engaging the threaded part of the other flange, a cam lever pivotally mounted on the exterior end of said rod and operatively engageable with said unthreaded flange to move said jaw members into clamping engagement with a jar after initial movement of said jaw members to a jar engaging position by the turning of said rod relative to said threaded part.
