CAN -FASTENER.

SPECIFICATION forming part of Letters Patent No. 397,555, dated. February 12, 1889. Application filed May 31, 1838. Renewed January 18, 1889. Serial No. 296,793. (No model.)

To aZZ whom it may concern.-

Be it known that we, CALVIN KEELER and HARVEY LEWIS, both of Hobart, in the county of Delaware and State of New York, have invented a new and Improved (an-Fastener, of which the following is a specification, reference being had to the annexed drawings, torming a part thereof, in which- Figure 1 is a front elevation of our improved can-fastener. Fig. 2 is a rear elevation showing the fastening-lever rais d. Fig. i) is a side elevation showing the fasteninglever raised. Fig. 4: is a longitudinal section taken on line or .r in Fig. 5. Fig. 5 is a plan view, and Fig. U is a sectional view, of a can, showin our improved Fastener applied to the cover of the can.

Similar letters of reference indicate corresponding parts in all the views.

The object of our invention is to provide a" simple and ettieient fastener for the covers of cans, to be used in connection with all kinds of cans having removable covers, but. especially designed for attachment to milk-cans.

Our invention consists oi? a grooved tasting in which is fitted a sliding hook adapted to engage the wired rim of the can and a camlever pivoted in the casting and arranged to bring thehook into engagement with the wired rim of a can, all as hereinafter more fully described and claimed.

The casting A, Formingthebodyot the fastener, is provided with a longitudinal slot, (1, at the sides ot' which are formed grooves Z) for receiving the fianges e of the sliding hook 1%. The said hook 13 projects below thelower surface of the casting A, and is adapted to engage the wired rim 0 of the can D. In the slot a is pivoted a cam-lever, E, having a 1011- gitudinal slot, (7, at the sides of which are formed curved slots 6 in the material of the lever, which approach the pivot oi the lever in an approximately spiral line. A stud, F, projecting from the hook l3, enters the slot (1 ot the cam-lever, and provided with a head,

j, which is received in the curved slots 8.

Bytnrning the lever E on its pivot, so as to lift it out of the groove in the casting A, the hook 1; will be. drawn outwardly toward the pivot of the cam-lever E, thus releasing it from the wire rim 0, so that the cover to which the fastener isapplied may be removed from the can. The cover is tastenml by reversing the operation just described. One or more of these fasteners may be applied to a cover.

The casting A is secured to the cover by means of rivet-s or soldering.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The eomliination, with a slotted casting, A, provided with grooves b, of the hook B, having flanges 1, fitted to the grooves and the cam-lever E, adapted to operate the hook, substantially as described.

2. The combination of the casting A, having the slot (1 and grooves I), the hook 15, provided with flanges (,1, iitt ed to the grooves b, and furnished with a stud, F, having a head,

f, and the (am-lever E, lflvoted in the casting A and prm'ided with aslot, (1, and grooves e, substantially as described.
