CAN-COVER REMOVER.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed February 7, 1920. Serial No. 356,876.

To all fui/om 'it may concern:

Be it known that I, HARRY B. SIEGMUND, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Can-Cover Removers, of which the following is a specification.

This invention relates to devices for facilitating the removal of the lids or covers of milk cans or other receptacles having a tight-fitting closure which is usually diihcult to remove, and the object of the invention is to provide a very simple and eiiicient device of this kind which is powerful in action so that the removal of an abnormally tight` fitting lid may be readily eiected.

The object stated is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing- Figure 1 is an elevation of the device; Fig. 2 is a vertical section of the device showing the manner in which it is used, and Fig. 3 is a plan view thereof. c

Referring specifically to the drawing, 5 denotes a fragment of a milk can or other container, provided with a tight-tting 11d 6. The device for effecting the removal of the lid comprises a supporting member and a lever mechanism for exerting an upward thrust or pull on the lid.

The supporting member is a cylinder 7 open at both ends, and reinforced by top and bottom rings 8 and 9, respectively. The" inside diameter of the cylinder is such that it may be slipped down over the neck of the can 5 to inclose the lid 6, as shown in F ig. 2, the bottom ring 9 seating on the top of the can, and the latter therefore serving as a support for the cylinder.

On the top ring 8 are outstanding ears 10 to which are pivoted, as shown at 11, hand levers 12, two diametrically opposite ones of such levers being provided. The pivoted ends of the levers have lateral bends 13, and the levers are therefore of the bell-crank type. The bends 13 pass through vertical slots 14 in the cylinder 7, and inside the latter, they carry depending lifting links 15, said links being pivoted to the lever bends, as shown at 16. The links 15 have on their edges which face the lid 6, a vertical series of hooks 17, any one of which is engageable with the edge of the lid, as shown in Fig. 2.

By providing the links with a plurality of hooks, the device is readily applicable to cans of different dimensions.

Adjacent to the points of attachment of the links l5 to the lever bends 13, the latter have outstanding abutments 18, which may be pins. These abutments are opposite the edges of the links which have the hooks 17.

In use, the cylinder 7 is seated on top of the can 5 as shown in Fig. 2.. Before this can be done, it is necessary to swing the lifting links outwardly a sufiicient distance to clear the lid G. This is donc by gathering or bringing the hand levers 12 together. IVhen this is done, the abutments 18 are carried against the links, and the latter are swung outwardly, as shown in Fig. 1. The links are free to swing in this manner as they are pivoted to the flevers. After the cylinder has been properly positioned on the can, the levers ai'e spread slightly to allow the links to swing inwardly for the engagement of their hooked edges with the lid, as shown in Fig. 2. The levers are now grasped and spread, whereupon the links are drawn upwardly, and the lid is forced olf the can. A powerful leverage is obtained, and hence a tight-fitting lid is very readily removed.

I claim:

1. A device of the character described, comprising a cylindrical supporting member open at its ends, pivoted levers laterally bent at their pivoted ends, carried by said member, lifting links pivoted to said levers on said bent portions, thereby causing said lifting links to be drawn upwardly upon the spreading of said levers.

2. A device of the character described, comprising a cylindrical supporting member open at its ends and having side slots, pivoted levers carried by said member, lifting links carried by the levers and positioned inside the supporting member opposite the side slots, and means on the levers for swinging the links outwardly through said slots.

3. A device of the character described, comprising a cylindrical supporting member open at its ends and having side slots, pivoted levers carried by said member, lifting links pivoted to the levers and positioned inside the supporting member opposite the side slots, and abut-ments on the levers intercepting the links for swinging the same outwardly through the slots.

In testimony whereof I aiiix my signature.

HARRY B. SIEGMUND.
