In the late summer, when the housewife is preserving, a large number of jars and sealers are used as containers for the preserved material.

These jars and sealers are usually provided with a screw threaded metal cover ring which, when tightened on the container, press the glass cover down against a rubber gasket, to exclude atmospheric air from contaminating the contents.

In order to screw these rings down, the housewife must hold the. round container with. one hand while the other is used to rotate the screw ring. This operation is hard work, as the container slips. It requires strong fingers and wrist, and is often too much for the average housewife. Accordingly, she frequently waits until her husband comes home so he can give the final turns on. the rings. This waiting may result in spoilation of the contents.

The principal object of the present invention is to provide a simply constructed jar and sealer retainer which can be easily and quickly secured to a table and which will hold containers against rotation so the housewife can exert the full strength of her hands for the tightening or releasing of the screw rings.

A further object of the invention is to construct the device for the reception and retaining of various sizes of containers, and such that it can be quickly and easily operated for the handling of a large number of sealers in a short period of time.

A still further object of the invention is to provide means for varying the power of the grip on said containers.

With the above important and other minor objects in view, which will become more apparent as the description proceeds, the invention consists essentially in the construction and arrangement of parts hereinafter more particularly described, reference being had to the accompanying drawings in which:

Figure 1 is a perspective view of the device secured to a table top and with a quart sealer in position thereon.

2 type of strap'for use with various sized containers.

Figure 8 is a vertical section taken on the line 8-8, Figure 7.

In the drawings, like characters of reference indicate corresponding parts in the several figures.

A suitable table or work bench top is indicate by the numeral l. The frame of the retainer 2 is supported thereon and comprises a plate, formed with a square shaped trough 3' at the bottom. This trough straddles the edge of the top and is securedthereto by a screw clamp l which passes through the lower side of the trough. When this clamp is tightened up, the upper end contacts the lower face of the'table top and jams the said table top between the end of the clamp and a rubber pad 2, suitably fastened under the upper side of the trough. The other part of the plate 2 projects upwardly from the table top to form a flat standard 5.

A pair of angle brackets 6' are riveted to the front face of the standard 5, on the left hand side, and when being fastened, a hinge connection 6, shown in Figure 5, has the flat portion thereof caught between the angle brackets and the standard so that the same rivets secure all together. The rolled portion of the hinge connection project's outwardly to receive a spring steel strap l, laterdescribed.

The horizontal parts of the angle brackets" 6 are spaced slightly apart to receive the end of'a knife shaped lever 8 therebe'tween. This lever is fulcrumed on a stud 9 which passes through the angle brackets, and the opposite end of the lever is provided with a handle it for manual operation.

An L-shaped plate- Il', best shown in Figure 4, has the short end' riveted to the front face of the plate 2, at the right hand side. The plate ll extends forwardly under the knife lever 8' and is provided with three rectangular shaped holes (2 in the upper surface thereof, while theextending end is cut off at an angle as indicated at It. The front edge of the knife lever iscut-in at two places to form a short tongue [4, and this tongue is bent down so that it can drop into one of the holes [2 or be caught behind the angled end l3 of the plate II, when the knife lever is moved. thereover.

The spring steel strap T, previously mentioned, has one end provided with ahinge plate 1; riveted thereto. This hinge plate. is similar to the hinge connection 6, shown in. Figure 5, but has an upper and lower rolled portion on the open edge which meshes over the rolled portionv on the hinge connection, so that a pin can pass therethrough to hold both in hinged relationship and so connect the strap I to the standard 5. The strap 1 extends rearw-ardly of th plate 2, is bent in a U shape, and receives a flat rubber pad I on the inside surface to which it is held by rivets it. At spaced intervals, the rubber pad is provided with V-shaped vertical grooves H for purpose later described, while the extreme end of both the pad and the spring steel strap are held by inner and outer vertical metal strips I8, rivets I9 passing therethrough to hold them all together. A hole is centrally drilled through the strips Is for hooking the end of a coil spring 20, the opposite end of which is hooked into one or other of a line series of holes 2! in the face of the knife lever B. A second rubber pad 22, having spaced horizontal grooves 23, is glued or otherwise fastened to the rear surface of the flat standard 5.

In operation, the retainer is attached to the table top as above explained and the end of the spring 20 is hooked into one of the holes ZI, depending upon the amount of wrapping pressure desired on the walls of the sealer container. If hooked into the hole on the extreme left, the pressure will be light, whereas if it is hooked into the hole on the extreme right, the pressure will be greater. The knife lever is drawn back to the position shown in dotted outline in Figure 2 and the sealer container 24 is then inserted between the rubber pads I5 and 22, with the bottom resting on the table top. The knife lever 8 is then drawn ahead by manual operation of the handle II]. If the sealer is a quart size, the lever will be drawn ahead until the tongue I4 drops into the first rectangular shaped hole I2. At this position of the lever, a good gripping pressure is exerted on the container. If the sealer is a pint size, the lever is drawn ahead until the tongue I4 catches over the angled end I3 of the plate I I. As the container is now firmly held between the pads, the housewife can use the strength of both hands on the metal cover ring 25 to turn and tighten same on the container. If the container has a tendency to turn when this rotary pressure is applied, this turning movement creates a tighter wrapping pressure on the container walls due to the friction between the container walls and the pads. The grooves I! of the pads permit the rubber therebetween to move slightly and jam against the walls of the container, similar to the action of a Stillson wrench. The pad 22 merely acts as a cushion for the container to rest against, and at the same time, prevent metal contact against the glass of the container.

While the gripping action of the pad I 5 is not as great when the metal cover ring is to be removed, the tension of the coil spring 20 is usually suificient to give a good gripping pressure on the walls of the container. If more pressure is required however, the lever B can be drawn farther back to catch the tongue I4 in either of the other holes I2, or the spring 26 can be hooked into the extreme right hand hole 2 I.

While I have shown and described the operation of the device for use with pint or quart sized sealers, which are the sizes most commonly used, it can also be used with half-gallon sized containers by the addition of an adapter plate 25, shown in Figure 6. This plate is relatively wide, has a central rolled edge 25' on one side, the same as the hinge connection 6', while the other side is provided with an upper and lower rolled edge 26 the same as the hinge plate 1'. When a halfgallon sized container is to be clamped in place, the pin I is withdrawn to release thestrap 'I from the standard 5. The adapter plate is then connected in the same way to the standard and the strap I is connected to the opposite end of the adapter plate with another pin I B this arrangement, the strap 1 is made long enough to go around a half-gallon sized container and the device can be operated in the same manner as for pints and quarts.

If the housewife is preserving with odd sizes of either large or small containers, the modified form of strap 21, shown in Figure '7, may be used. The spring connecting end of this strap is the same as for the strap 1 but the hinge plate 28 is adjustable. Slightly back from the spring end, a series of central holes 29 pass through the strap at each section of the rubber pad, while the hinge plate is provided with a threaded stud 3i], receivable by said holes. A washer 3I and Wing nut 32 connect on the stud at the other side of the strap to hold the hinge plate firml thereto. By this arrangement the hinge plate can be moved to accommodate the strap to any size of container.

From the above description, it will be apparent that this device will free the housewife completely from having to hold the sealer containers while turning and tightening the metal cover rings. When filling the sealers she simply inserts the sealer container, draws the knife lever back and can then turn all her attention and strength against the metal rings. A flip of the knife lever and the finished sealer can be removed. This results in speedy and quick completion of her work without the tiring awkward operations above explained which often ruin her peace of mind for the rest of the day.
