CLAMP FOR SECURING COVERS OF JARS, 80C.

SPECIFICATION forming part of Letters Patent No. 247,547, dated September 27, 1881.

Application filed July 30, 1881. (N model.)

To all whom it may concern:

Be it known that I, SOLOMON M. EISEMAN, a citizen of the United States, residing in the city, county, and State of New York, have invented certain Improvements in Clamps for Securing the Covers of Jars, Cans, and other Receptacles, of which the following is a speci-.

fication. Y

My invention relates to a clamp or clamping device constructed independently of the receptacle and its cover, two or more of which may be employed, as desired, for securing the cover hermetically on the receptacle. These clamps may be applied to jars or receptacles for hermetically packing substances of all kinds, and they are adapted to large and small receptacles indifferently.

In the drawings, which serve to illustrate my invention, Figures 1 and 2 are respectively a front and side elevation, showing the clamp in its contracted condition, and Figs. 3 and 4 are corresponding views of the clamp in its extended condition. Fig. 5 is a sectional view, showing the application of the clamp to deep receptacles; and Fig. 6 is a similar view, showin g its application to shallow receptacles. The clamp in both cases is in substance the same; but in the first-named case it takes under a flange on the body of the receptacle instead of under its bottom, as in the last-named case.

A is the upper part or section of the clamp, which is provided with a hook or projection, to, to take over the cover of the receptacle, and B is the lower part or section, provided with a similar hook or projection, 12, to take over or engage the bottom edge of the receptacle, or a flange or projection thereon. Either section might be uppermost; but for various reasons I prefer the arrangement shown.

C is a clamping-lever, which is fulcrumed in the section A, by causing lugs or points on it to engage eyes 0 c in the said section, and the short arm 01 of said lever is coupled orlinked to an eye, 6, in the upper end of section B.

The short arm dis bent a little, so as to stand out, as shown in Figs. 2, 5, and 6, when the clamp is contracted beyond the fulcrum-point, whereby the clamping-strain tends to tighten the clamp and to draw the lever 0 more closely in against the section B.

When the free end or long arm of the lever is drawn outward or lifted (see dotted line in Fig. 2) it will, after the fulcrum passes outside of a vertical line passing through the coupling at c, fly up and release the clamp.

Referring'to Figs. 5 and 6, D represents an ordinary preserving-jar, and E its cover, the latter being provided, by preference, with a turned-down flange, to rest upon a rubber packing-ring or gasket, g, and a raised ledge or flange, h, for the upper end of the clamp to take over.

If the jar or receptacle be shallow,as in Fig. 6, the clamp may take under its bottom, and I prefer this arrangement for small jars; but if it be deep, I prefer to form on the body of the receptacle a lug or lugs or flange, i, for the clamp to take under, as shown in Fig. 5.

To prevent the lever G from being lifted accidentally, thus disengaging the clamp, I may provide some form of catch or holdfast to keep it down. In Figs. 1 and 2 I have shown such a device in the form of a slide-ring, j, on the section B, arranged to be slipped over the free end of the said lever, as shown in Fig. 6. \Vhere such a holdfast is employed it is not so necessary that the short arm of the lever be bent outwardly; but I prefer to so construct it. I may in some cases provide the lower section, B, with a projection, 70, on itsinner face, to rest against the body of the receptacle and keep the clamp from being pressed in at that point, which would be liable to disengage the clamp if no holdfast for the lever were employed.

The clamp may have more or less extensibility, as desired, and may be made to fit receptacles of a certain size or height; or the lower section, for instance, may be made indefinitely long and be cut and bent to fit any receptacle, as required.

At least two clamps will be required for ordinary receptacles, and I may employ more than two when more are deemed necessary to hold down the cover firmly.

Having thus described my invention, I claim 1. A clamp for securing the covers on receptacles, comprising one part or section to take over the cover, another section to take over ICQ the bottom edge of the receptacle or a projection thereon, and a lever fulcrumed in one section and coupled to the other section, all ar-' ranged to operate substantially as herein set 5 forth.

2. The combination, to form aelainp for holding down the covers of receptacles, of the up per and lower sections provided with hooked extremities to engage the cover and 3' ar, respect to ively, the lever fuleruined in bearings on one section and its short arm coupled to the other section, and a securing device, substantially as shown, to keep the free end of the lever'up to the clamp, all arranged to operate as set I 5 forth. l

.3. The combination, to form aclamp for hold- SOLOMON M. EISEMAN.
