3 Claims.

This invention aims to provide a means whereby fruit jars and the like, may be held whilst the closure of the jars is being threaded off, the device being capable of accommodating jars of different diameters, without breaking any of them. A further object of the invention is to provide novel means for actuating the slidable jaw. A further object of the invention is to provide novel'means for holding a cooperating jaw in adjusted positions.

The invention aims, further, to provide a device of the class described, in which the parts cooperate to reinforce each other, a simple but unusually strong construction resulting.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 is a plan view of the device;

Fig. 2 is a view in side elevation;

Fig. 3 is a longitudinal section;

Fig. 4 is a front elevation and Fig. 5 is an enlarged sectional view on line 5-5 of Fig. 4.

For convenience in describing the relative location of parts that end of the frame to which the letter A is applied will be considered as the front end. The frame includes a horizontal base I,

- preferably of rectangular outline and generally made of wood, the base being adapted to be held by a clamp (not shown) on a table or other work place. Near one end, the base I is supplied with an upstanding stop lug 2. A vertical bracket 3 is secured to the base I, a little in advance of the stop lug 2, and preferably is made of wood.

Upstanding metal wings 4 are secured to the outer edges of the base I and to the ends of the bracket 3. The parts 3 and 4 reinforce each other. The wings 4 are provided in their upper edges with vertical slits 5, spaced apart longitudinally of the base I.

Jaw blocks, preferably of wood, are provided, and a first jaw block 6 is located between the wings 4 .and rests on the base I. A retaining plate I is secured to the rear surface of the jaw block 6 and projects slightly beyond the ends of the jaw block, so that the terminal portions of the retaining plate may be received in any of the slits 5. At its outer ends, the retaining plate I is provided with rectangularly disposed flanges 8, the flanges overlapping the outer surfaces of the wings 4 and preventing the wings from springing outwardly. The wings 4 are disposed closely adjacent to the end surfaces of the first jaw block 6, and there is small chance that the wings will be bent inwardly.

Guide plates 9 are secured to the edges of the base I, near the front end of the base. The guide plates 9 are supplied with inwardly projecting, rectangular flanges I0.

A second jaw block II is mounted for reciprocation on the base I, between the guide plates 9, and is provided in its ends with grooves I2, receiving the flanges I II of the guide plates 9. Thus, the jaw block II is held down on the base I, for reciprocation toward and away from the jaw block 6.

A reinforcing cross piece I4 is secured by attaching elements II to the rear surface of the jaw block I I. The jaw blocks 6 and I I preferably are made of wood, as is the base I. The cross piece I4 strengthens the jaw block II, and the retaining plate I strengthens the jaw blocks 6. Slotted latches I5 are mounted to swing on the attaching elements I'I.

The ends of the cross piece or strap I4 extend outwardly beyond the ends of the jaw block II, and are provided with openings I8, wherein operating rods I9 are received. Tubular nuts 20 are threaded on the front ends of the rods I9 and are equipped at their rear ends with annular heads 2I. The ends of the strap I4 abut against the rear surfaces of the heads 2| of the nuts 20. The latches I5 can be swung downwardly, until the latches straddle the nuts 20, in front of the heads 2|. Thus, the jaw block II is operatively assembled with the rods I9.

If it be desired to take off the jaw block II, the latches I5 are swung inwardly, [clear of the nuts 20, the nuts are threaded off the rods I9, and the jaw block II can be slid forwardly, off the flanges I0 of the guide plates 9.

A forked lever 22 is provided, and the forward ends of the operating rods I9 are pivotally mounted in the arms of the lever 22. The arms of the lever 22 overlap the outer surfaces of the Wings 4, the lever being mounted to swing vertically on fulcrum elements 23, such as screws, .passing inwardly through the wings 4, into the end cfthe bracket 3. The intermediate or rear portion of the lever 22 is equipped with a handle 24, and when the lever is swung downwardly, the handle comes into contact with the stop lug 2, the pivotal mounting of the rear ends of the rods IS in the side .arms of the lever being located below the fulcrum elements 23, and, therefore, the lever cannot swing upwardly, unless it is moved upwardly by hand.

The inner surfaces of the jaw blocks 6 and H are supplied with arcuate recesses 25, in which are located thick cushions 26, preferably made of sponge rubber. The ends of the cushions 26 overlap the adjacent surfaces of the jaw blocks 6 and II, at the outer ends of the jaw blocks. Washer plates 27 overlap the ends of the cushions 26. Securing elements 28 pass through the washer plates 2'! and through the ends of the cushions, into the jaw blocks 6 and II, the cushions thus being held in place securely: although, if desired, the cushions 26 can be cemented into the recesses 25 of the jaw blocks, without change in the showing of the drawings. The washer plates 2'? are notched, as shown at 29, to accommodate the flanges In of the guide plates 9, when the movable jaw l l is reciprocated, and a metalto-metal contact is afforded.

The jaw block II is reciprocated by means of the rods i9 and the lever 22. The fruit jar to be opened is clamped tightly between the cushions 28. Different sized jars may be accommodated by inserting the end portions of the retaining ,plate I in the selected ones of the slits or seats 5 in the wings 4. The cushions 26 are thick enough and resilient enough to accommodate and hold different diametered fruit jars, without danger of breaking. When the fruit jar thus is held, the cap may be threaded off by means of a wrench or other tool forming no part of the present application, and not shown.

The device is simple in construction, but will be found thoroughly advantageous for the ends in view.

Having thus described the invention, what is claimed is:

1. In a jar holder, a frame including a base, a normally stationary jaw on the base, a jaw slidable on the base, toward and away from the stationary jaw, a strap on the forward surface of the slidable jaw, the ends of the strap projecting beyond the ends of the slidable jaw, attaching elements connecting the strap with the slidable jaw, operating members having their forward ends extended through the ends of the strap, nuts threaded on the forward ends of the operating members and engaging the forward surface of the strap, latches pivoted on the attaching elements and engaging the nuts to prevent them from backing off the operating members, and a lever fulcrumed on the frame, the rear ends of the operating members being assembled pivotal'ly with the lever.

2. In a jar holder, a frame including a base, a normally stationary jaw on the base, a jaw slidable forwardly and backwardly on the base, toward and away from the stationary jaw, the slidable jaw being made of soft material, typically represented by wood, and having grooves in its ends, metal guide plates secured to the base and having inwardly extended flanges received in the grooves, a cushion on the working base of the slidable jaw, metal washer plates on the forward surface of the cushion, at the ends thereof securing elements passing through the washer plates and entering the slidable jaw, the washer plates having notches receiving the flanges and affording a metal-to-metal sliding connection between the slidable jaw and the guide plates, and means for operating the slidable jaw with respect to the stationary jaw.

3. In a jar holder, a frame comprising a base, an upstanding bracket on the base, wings secured to the ends of the bracket and to the outer edges of the base, the wings having slits in their upper edges, a first jaw on the base and fitting closely between the wings, to prevent them from bending inwardly, a cross piece secured to the rear surface of the first jaw and including extensions removably lodged in the slits, the extensions having flanges engaging the outer surfaces of the wings, toprevent them from bending outwardly, a movable jaw carried by the frame, and means for operating the movable jaw forwardly and backwardly with respect to the first jaw.
