Patented Aug. 16, 1938 UNITED; STATES PATENT OFFICE JAR HOLDER Andrew John Kriska, Cleveland, Ohio Application April 21, 1937, Serial No. 138,091

2 Claims.

My invention relates to jar holding devices and in particular to that type of device which provides an efficient and practical method for holding jars firmly while caps or covers are screwed on or off.

One object is to provide a device which is adaptable to any size jar and has means therein whereby a positive clamping is secured by manipulating a handle at one corner of the said device.

Another object is to provide a structure which may be manufactured at a minimum cost.

These and other objects and advantages may be noted from the following specification and its accompanying illustrations, in which:

Fig. 1 is a perspective view of the device show- ,ing the method of operation.

Fig. 2 is a top plan view, with the jar in section, showing the position of the device necessary to tighten the cap or cover on the jar.

Fig. 3 is a side elevation of Fig. 2.

Fig. 4 is a top plan view similar to Fig. 2, but showing the device in the position necessary for removing the cap or cover from the jar.

Fig. 5 is an enlarged elevation of the operating handle.

Fig. 6 is an enlarged view of the locking device for securing the operating handle to the jar holding device.

Referring again to the illustrations, a pair of channel members of unequal length are provided; the forward channel member l0 being longer than the rear channel member II, both having a longitudinal stiffening rib 50 as shown in Figs. 1 and 3.

Long links I2 and I3 are pivotally secured to the top and bottom flanges Illa and Ila and I011 and Nb respectively of the channel members Ill and II, above and below said members, by a pivoting post I4 therethrough at the forward end and by a pivoting operating handle post I5 at the rear end of said long links I2 and I3 said handle being secured by a lock washer I512; inserted over the narrow portion I5b= at the lower end of the handle post I5c.

Short links I6 and Il are pivotally secured to the flanges Illa and Ila and Illb and Nb respectively at the opposite end of the channel members l0 and II above and below said members by pivoting posts I8 and I9 respectively.

A plurality of strips or panels 20 and 2 I, having a rough or uneven outer surface, such as corrugated rubber or the like, are secured to the inner surfaces of the channel members Ill and II respectively, by vulcanizing, riveting or the like.

The short link I6 terminates in a flanged end I6a with an aperture 22 therethrough; a short sliding spring member 23 has a rearwardly projecting portion 23a. also with an aperture therethrough; a pivot pin 24 is secured through the aperture 22 in the flanged end Ilia of the short link I6, and the aperture in the projecting portion 23a of the sliding spring member 23, thus securing the end of the sliding spring member to the flange of the short link I6.

A long sliding spring member 25 is pivotally secured to the top surface of a toggle or cam lever 26 by a pivot pin 21, the toggle lever in turn being pivotally secured by a pivot 28 to an angular plate 29 mounted on the outer surface of the channel member I0 and secured by rivets 29a or the like.

The long sliding spring member 25 is shouldered on both edges at 25a, the short sliding spring member 23 being superimposed over the smaller portion 25b, thus formed, of the said long sliding spring member.

A notch 3|] in the outer edge of the long sliding spring member 25 adjacent to the shoulder 25a retains therein one end of the spring 3| which is superimposed over the smaller portion 25b of the long sliding spring member 25 and the short sliding spring member 23 mounted thereon, the opposite end of the spring 3| being secured around an outwardly projecting segment or portion 32 of the short sliding spring member 23.

Clamps 33 and 34 are rigidly secured to the lower flange "lb of the channel member Ill and provide a means whereby the jar holding device may be secured to a table top 35.

In operation the device is secured to the table top 35 by clamps 33 and 34, the operating handle I5 is moved to its normal position, directly in line with the pivot post I4, the jar 36 is inserted between the channel members II] and I I and, when filled, the cap or cover is then placed on the jar, the operating handle I5 is pushed to the left until the jar is firmly gripped between the channel members II] and II, the corrugated rubber surfaces of the panels 20 and 2| retain the jar securely therebetween and thus eliminate any fear of slipping. The cap is then screwed down'securely on the threaded neck of the jar, in the direction indicated by the arrows in Fig. 2.

The spring unit on the front channel member IEI being in the position shown in Fig. 2, the sliding spring member 23 being in the open position with the spring 3| expanded, thus creating a tension which tends to cause a tighter grip on the To remove a cap or cover, the jar is placed as before, but the operating handle I5 is drawn to the left, the cam lever 26 is reversed as shown in Fig. 4 and the jar is again held rigidly between the channel members l0 and II with the pressure on the jar reversed to offset-the reverse motion in removing the cap or cover, the direction being indicated by the arrows in Fig. 4.

Thus in either action as illustrated by Figs. 2 and. 4 respectively, the harder the cap or cover is turned on or off of the neck of the jar, the tighter the jar 36 becomes wedged between the channel members I0 and H.

I claim:

1. A jar holder comprising a pair of opposed gripping members disposed at an angle to each other, one member being fixed and the other shiftable lengthwise to effect a clamping action, swinging links of fixed length pivoted to opposite ends of the respective members, a spring connected at one end to one of the links, and tending to shift the link and the shiftable member in one direction, and a toggle pivoted to the fixed member and connected to the other end of the spring.

2. A jar holder as in claim 1, the swinging links comprising a pair thereof at the top and bottom respectively of each end of the gripping members.
