COMBINED CAN OPENER AND SEALING DEVICE Filed Nov. 16, 1928 INV ZQR 4/ ATTORNEY Patented Apr. 21, 1931 PATENT OFF-ICE HUGH T. HUGHES, O1 CLEVELAND, OHIO COMBINED CAN QPENER AND SEALING- DEVICE I Application filed November 16, 1828. Serial No. 819,898.

The objects of the invention are to provide an improvement in can opening devices by means of which a simple device attachable to any can, can be used to provide a ouring opening in the cover of the can and s1mu1- taneously therewith will provide an opening for the admission of air in the cover, thus permitting the liquid therein to flow freely from the pouring opening; also the means employed for piercing the can are subsequently employed to seal the opening they produce, and thus to preserve the contents of the can from fermentation.

The device is particularly applicable for domestic use when applied to cans containing evaporated milk, or syrup or other liquid foods, but can be applied to any can containing liquids that are hermetically sealed and from which it is desired to exclude the air when only a part of the contents has been' used.

The invention is illustrated in the accompanying drawings, hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings; Fig. 1 is a planof a simple form of the device; Fig. 2 is a vertical section thereof; Fi 3 is a front elevation of the same; Fig. 4 1s a plan of an adjustable form of the device; Fig. 5 is a vertical section thereof; Fig. 6 is a front elevation thereof, and Fig. 7 isa planpf a simple form of adjustable device. F1 8 shows a modified form of spring there or; Fig. 9 shows an ornamental holder for table use; Fi 10 shows one manner of use of an attac ing clamp, Figs. 11, 12 and 13' show pivoted levers and circumferential clamps. In these views A is the top of the can; B is a plate having downwardly turned edges C that are forced over the edges of the can to hold the plate in place thereon; D is a metal bar or lever resiliently mounted upon" the plate B in such a manner that it can be tilted 4 vertically thereon, and is provided with spaced piercing points or projections E and F respectively, which pass through openings G and H in the plate B and rest upon the cover of the can until the bar D is struck from above by the hand or by a hammer or any convenient tool, when the points will pierce the cover at G and H.

When the bar is lifted the opening G can be employed for pouring, and air will be admitted through the opening H, and when released the bar will fall, and the points will reenter the openings they have reviously made, and will hermetically seal t cm, since they will fit the openings closely.

The bar is raised by pressing upon its outer end at I and may be resiliently connected with the plate by means of a spring J integral with the plate, or may be plvoted upon the plate or attaching clamp and pressed upon by the spring K as shown in Figs. 8, 9, 11 and 12.

The pressure of the spring will retain the points pressed into the openings so that air cannot enter the can.

In this manner the contents can be preseried from fermentation until it has all been use In Figs. 4, 5, and 6 the modification of a longitudinal adjustment for the plate is shown to ada t it to several sizes of cans and the plate is ormed in two portions B, B, one portion sliding in ides B2 in the other portions, and provide with lateral lugs B3 that prevent the arts from separating.

The plate B is branched in front at B4 to provide a s ace between the arms for pouring so that the 'quid will not come in contact with the plate.

In Fig. 7 the plate is provided with a number of spring arms B5 which are resilient enough to permit the plate to be attached to cans of several sizes.

In Fig. 9 an ornamental holder M takes the place of the plate B, and a handle N is attached thereto. In Fi s. 10, 11 and 12 a horizontal and circum erential attaching clamp O is shown.

The device is simple, efiicient and of sli ht initial cost and fills a much needed want or a can opening tool that will hermetically seal the can after it has been opened.

In Fig. 12 the attaching-clamp is looped at I and the lever D is fpivoted in the loo Other modifications o the device may made within the scope of the claims.

Having described the invention what I claim-as new and desire to secure by Letters Patent is,

1. In a can puncturing and sealing device, a clampin support attachable to said can transverse y thereof and a bar or lever resiliently mounted to tilt vertically therein, said bar being provided with spaced vertical pointed projections in line therewith adapted to be forced through the cover of said can, when pressure is applied to said tilting bar a portion of said transverse support bein separated therefrom to form a spring, sai bar being mounted on said spring.

2. In a can puncturing and sealing device, a clamping support attachable transversely to the cover of the can, and a bar resiliently mounted to tilt vertically thereon, said bar being provided with spaced pointed projections adapted to be forced through the cover of said can, when pressure is applied to said tilting bar, and plate being made in two portions adjustably connected together.

In testimony whereof I aflix my signature.

HUGH T. HUGHES.
