SCREW-CAP FOR CANS, TANKS, s60.

SPECIFICATION forming part of Letters Patent No. 629,982, dated August 1, 1899. Application filed December 80, 1898. Serial No. 700,737. (No model.)

To aZZ whom it may concern:

Be it known that I, CLARK THOMPSON BRANT, a citizen of the United States, residing at Charlton, in the county of Lucas and State of Iowa, have invented a new and useful Improved Screw-Oap for Cans, Tanks, &c., of which the following is a specification.

The invention relates toimprovements in caps for cans, tanks, and analogous receptacles. The object of the present invention is to improve the construction of'screw-caps for cans, tanks, and analogous receptacles, more especially the means employed for enabling the caps to be screwed on or oft such cans and tanks, and to provide a simple, inexpensive, and efficient device adapted to be readily operated and capable of enabling screw-caps to be placed tightly on cans, tanks, and the like to effect an air-tight joint and of permitting such caps to be conveniently removed without injuring them or the receptacles.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended;

In the drawings, Figure '1 is a perspective view of a portion of a receptacle provided with a screw-cap constructed in accordance with this invention, the lever being in engagement with the lugs. Fig. 2 is a plan view of the same. view of one of the lugs.

Like numerals of reference designate corresponding parts in all the figures of the draw ings.

l designates a metal screw-cap engaging a receptacle 2 in the usual manner and provided at diametrically opposite points with vertical metal lugs or flanges 3, arranged parallel with each otherand located adjacent to the periphery of the screw-cap and adapted to be engaged by a lever 4. The lugs V or flanges are preferably constructed of sheet metal folded upon itself to form a stiifened central portion of two plies and bent outward from the base of the same to form attachment flanges or portions, which are soldered or otherwise secured to the upper face of the cap. The vertical end edges of the flanges are provided with series of recesses or notches, form- Fig. 3 is a detail perspective ing teeth 5, which are adapted to engage the edges of the lever 4:, and the latter is preferably constructed of wood in order that the notches or recesses 7 and 8, located adjacent to the end portions of the lever and disposed at opposite sides of the same, the lever being adapted to project from both sides of the screw-cap, so that it can be readilyhandled in screwing and unscrewing the same. One end of the lever is shaped to form a handle 9, and by providing the recesses or notches 7 and 8 at both edges of the lever the latter is rendered reversible and is adapted to engage the lugs at either side and can be arranged quickly in position for rotating the screw-cap in either direction without changing it from one side to the other.

The invention has the following advam.

tages: The device, which is simple and com parativelyinexpensive in construction, is ap plicable to the screw-caps of tanks, cans, and analogous receptacles, and the lever which engages the lugs may be constructed of wood and is adapted to be readily reversed at either side of the screw-cap for rotating the latter to screw it on or remove it from areceptacle. The notches of the lever prevent the same from slipping longitudinally when in engage+ ment with the lugs or flanges, and the teeth or recesses of the same bite into the wood and prevent the lever from slipping upward.

These teeth also enable the cover to be unscrewed or placed on a receptacle by any ordinary piece of board, such as a part of the cover of a wooden box, and they will prevent the same from slipping out of engagement and capable of permitting the same to be reeither position of the lever and capable of versed to engage either edge of the lug,wherepreventing the letter from slipping longitudiby the cap may be screwed on or off, snbnally, substantially as described. stantially as described. In testimony that I claim the foregoing as 5 2.
