LOUIS HONSTEIN, OF PORTLAND, OREGON.

CLAMP FOR FRUIT-JARS.

To all whom it may concern:

Be it known that I, LOUIS HONSTEIN, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Clamp for Fruit-Jars, of which the following is a specification.

This invention relates to clamps for holding fruit jars, on a table, or other sup ort, while thecap is being screwed onto, or 0 of a ar.

In preserving fruit in glass jars, there is great trouble and difficulty in screwing the cap upon the jar, as the contents render the jar extremely hot, makin it difficult to handle the ar, while the cap is screwed on tight. Also, in unscrewing the cap, the 'ar must be held firmly to unscrew the cap, W ich is done with difliculty, as the cap becomes wedged in ace.

p The object of this invention is to provide an im roved clamp for holdin a fruit jar to a tab e, by means of which t e jar will be firmly held in place, and prevented from becoming loose, and working off of the table, and by means of which also, the jar may be readily clamped in place and held from turning.

The invention consists of an improved fruit jar clamp, constructed, as hereinafter set forth and claimed: 7

Referring to the drawing, Figure 1 is aperspective view of a fruit jar clamp constructed in accordance with this invention, and shown as secured to the ed e of a table. Fig. 2 is a side view thereof. Flg. 3 is a erspective view of the movable jaw detac ed.

The clamp consists of a circular plate 1 of iron, or wood, or other suitable material, and formed at one side with a fixed curved jaw 2, adapted to fit against the side of a glass fruit jar. At the opposite side from the fixed jaw, the late 1 is formed with an extension 3, provid ed with parallel slots 4,'each open at its outer end, and each communicating at its inner end with an opening 5 in the plate 1. An arm 6 extends between said openings 5, and projects beyond the extension 3, terminating in an upturned end, or bracket 7, the arm 6 forming with the extension 3 the slots 4. Resting on the extension 3 is a curved slidable jaw 8, having on its lower edge the inclined lugs 9, which project through the slots 4, and embrace the inclined sides 10 of the arm 6, the lugs 9 serving as guides to steady-the jaw 8 in its movement.

Specification of Letters Patent. Application filed May 6, 1908. Serial No. 431,269.

Patented Oct. 20, 1908.

Thejaws 2 and 8 each have their inner clamping surface preferably provided with a strip of rubber 11, secured thereto by glue, or otherwise, the rubber surface preventing injury to the glass jar, and holding it from slipping. The jaw 8 may be operated by any suitable means, and, as here shown, referably by a screw shaft 12 having a cran handle 13. The screw shaft 12 extends through and engages a screw-threaded hole 14 in the bracket 7, and has its forward end unthreaded and projecting into a hole in the slidable jaw 8, and connected to the jaw 8 in any suitable manner to turn freely thereon.

In order to firmly secure the clamp to a table, or other suitable support, the plate 1 is provided on its under side with an L- shaped bracket 15, having a clamping screw 16 extending through the bracket 15, with a clamping head 17, pivoted on its outer end. To steady the plate 1 against lateral movement, when it is clamped to a table, it is provided on its under side, at a suitable distance from the bracket 15, with two lugs or projec tions 18, adapted to bear against the edge of a table.

When the clamp is attached to the edge of a table, the plate 1 rests on the table, as shown, and the bracket 15 and lugs 18, bear against the edge 19 of the table. The clamping screw 16, bearing tightly against the under side of the table serves to hold the clamp firmly thereon, the lugs 18 at a spaced distance from the bracket 15, on either side thereof holding the clamp from moving laterally when force is applied to screw on a cap, or unscrew it from a ar. A glass jar 20, as shown in dotted lines in Fig. 1, having been placed on the plate 1, with one side of its lower end abutting against the fixed jaw 2, the slidable jaw 8 is advanced against the opposite side of the jar by operating the screw 12, and is brought to bear firmly against it, thereby securely holding the jaw in clamped position. The clamp is adapted to hold jars of different sizes, and a jar may be easily and quickly clamped thereon by a single turn of the screw 12; A ar being firmly and rigidly clamped on a table, as herein set forth, a cap can be conveniently and readily screwed on or off of the jar.

What is claimed is 2-- 1. A fruit jar holder comprising a base member havin a fixed jaw and provided with an integra clam ing bracket, a clamping member carried y said bracket, that portion of the base opposite the fixed aw bel ing arranged to form a guiding bar, a slidable jaw mounted on the guiding bar and means for operating the slidable aw.

2. A fruit jar holder, consisting of a base having a fixed jaw on one side, and a guide bar, and guide slots on its opposite side, a slidable aw having guide lugs engaging said guide bar, means for operating the slidable jaw, and means for clamping the holder to a support.

3. A fruit jar holder, consisting of a base having a fixed jaw on one side, and a slotted projection, and guide arm with tapering sides and bracket on its opposite side, a slidable jaw with tapering lugs engaging the slots in the projection and the guide arm, an operating screw shaft mounted in the bracket of the guide arm, and connected to the slidable jaw, a bracket with clamping screw depending from the base, and steadyin lugs on the base on opposite side from the lamping bracket.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

LOUIS HON STEIN.
