IMPROVEMENT IN PRESERVE-CANS.

Specification forming part of Letters Patent No. 36,264, dated August 19, 1862.

T0 aZZ whom it may concern:

Be it known that I, HENRY S. FIsHER, .of Newburg, in the county of Cumberland and State of Pennsylvania, have invented a new and Improved Preserve- Can; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, like letters indicating the same or analogous parts, and in which drawings.

Figure l is a sectional view of my improvement; Fig. 2, a plan view of the same; Fig. 3, a plan view of the top of a preserve-can with a cap thereon made according to my'present improvement; and Fig. 4, a section of the plan view shown in Fig. 3. Fig. 5 shows an approved form of constructing the body of a preserve-can, and an approved mode of apply-- ing a tubular screw-cap thereto shown in perspective in Fig. 6. Figs. 7, 8, and 9 are also views showing preserve-cans and approved modes of securing the caps to the top of the same, Figs. 5, 7, 8, and 9 all being views of preserve-cans with modes of fastening on the sealing-cap, adapted for use in case transpon tation for long distances is necessary. l

I would state that the devices shown in Figs. 5, 6, 7, S, and 9, although of an excellent character and which may furnish hereafter the subject-matter of separate and distinct applications for patents, do not in this my present application form the subject-matter for a patent.

The subj cot-matter of this patent is particularly shown and designated in Figs. 1 and 2 of the drawings; and it consists of a circularformed can, a, having at its top an orifice, b, of circular form for ingress to and egress from the body of the can. The edge of this orifice b is turned up, as at 0, above the surrounding main portion (2 of the top of the can, in order that a fillet, g, of paper saturated with beeswax or other proper material which is hard and non-adhesive when cold but which will become adhesive under a gentle heat, may be applied on top of the elevated edge 0, as shown, and be pressed around the side of said elevation, as at f, and also on top of the can at portions marked d. The fillet marked 9 is shown in proper position in Fig. l, with the can scaled up, and is immediately held in place by a peculiar-formed can-cap, H. This cap is formed by simply cutting out a disk of proper size from a sheet of tin, and then with a proper tool a bulge or oval or spherical projection, z, is formed in its center, as indicated in Figs. 1, 3, and 4, leaving the surrounding portions of the cap flat, as at a? in said figures. This oval projection, as will be seen in Fig. 1, is at its base just of a proper diameter to fit over the projecting edge 0., and when placed in position, as shown in Fig. 1, presses down the fillet 9 upon the top of 0 as well'as causing the fillet to hug the outer side of c,

and also to be snugly pressed upon the portions (1 of the top of the can. The oval projection of cap H just named also serves as an elevated point over which to spring a bar, 76, one end of which is inserted in a loop, Z, and the opposite end sprung down beneath ahook, m, as shown in Figs. 1 and 2.- By thus constructing the cap H, the necessity for the insertion of wedges between the cross-bar and the can-cap, as heretofore done, and the trouble arising from the loss of the wedges, is obviated. Beside this difficulty, the shrinking of wooden wedges ordinarily used, and a consequent leakage of air into the can from such cause, is also avoided by such mode of constructing the can-cap, to say nothing of its simplicity and cheapness.

Having reference to Figs. 1 and 2, we will suppose the can-cap to be removed, and that the body of the can has just been filled with preserves in the usual heated state. Theoperator then lays the fillet 9 over the orifice b, the heat of the body of the can causing the adhesive quality of the fillet to become developed. The can-cap H is then placed upon the fillet, as represented in Figs. 1 and 2, and the rod is inserted in the loop Z and sprung down beneath the hook m, its central portion resting upon the bulge i, as shown. This operation causes the base of the bulge z to llllpinge upon the fillet, causing the latter to hug the sides and top of the elevated portion 0 and be drawn taut over the mouth or orifice b of the can, as well as, causing the fillet to be firmly pressed upon the main top portion, (i.

In this manner it will be seen that the fillet g is caused to have an airtight-joint contact with the main top of the can at three points, allof which are in different planes, and by means of which the can becomes effectually sealed.

I would here state that the fillet 9 may be made of paper saturated with beeswax, as

before stated; or the adhesive material may be made of a compound of coal-oil and resin. Having thus described my said invention,

' what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The cancap H, constructed with the plane portion cl and bulge portion 2', in connection with a can-top having a central orifice through it, all substantially in the'manner and for the purpose specified.

2. The combination of the cap H, constructed as described, pan-top, and clamp 70, substantially in the manner and for the purpose described.

3. The cap H, in combination with the orifice-elevation a and fillet g, in the manner and for the purpose substantially as described.

HENRY S. FISHER.
