To (ir/ZZ 1,071,011@ it may con/cern:

Be it known that I, GEORGE GRAHAM, a citizen of the United States, residing at Dorchester, in the county of Wise and State of Virginia, have invented certain new and useful Improvements in Oil-Flasks, of which the following is a full, clear, and exact specification.

This invention relates to miners oil-flasks.

In mining' operations it is well known that the miners have attached to their caps a small lamp to give them light in carrying on their work and that said lamps must from time to time during the day or during a shift be refilled as the oil is consumed.

The object of this invention is an oil-flask to be carried in the miners pocket from which to refill his lamp when necessary; and to this end the invention consists, broadly, in a ask or receptacle normally closed by a valve which prevents escape of oil. the flask and its valve being so arranged that it may be readily withdrawn from the pocket and manipulated to fill a lamp by the use of one hand, the other hand being free to hold the lamp.

In the accompanying drawings, in which similar letters of reference are used to indicate corresponding parts in each of the several views, Figure l is a perspective view of a miners oil-fiask embodying my invention. Fig. 2 is a top plan view thereof, the valve being shown in a position to close the flask. Fig. 3 is a section on Ithe line 3 3 of Fig. Q, and Fig. 4f is a top plan View of Fig. 3 with the valve removed.

The flask A is preferably made of metal and of oval or attened shape to lie flat against the person and may be stamped from sheet or cast, as economy and convenience may dictate.

The flask at its upper end is made small to be encircled by the hand and terminates in a plug A somewhat thicker than the body of the flask for a purpose to be hereinafter explained. This plug A may be formed integral with the `body of the iiask or be secured immovably thereto by an impervious joint a, formed by spinning' the neck of the body upon the periphery of the plug or by solder. The plug is provided at diametrically opposite points adjacent to and preferably equidistant from the periphery with apertures a and a2 to provide for the free pouring of oil from the one, while air may enter through the other to facilitate the flow ofoil. The plug is further provided at a suitable point with a large opening a3 to be used in filling the flask and centrally with a tapped hole a4. i

Above the top of the flask-mouth and plug A is secured a disk valve B circular in contour and having a depending flange I); which fits snugly upon the iiask-mouth, as shown in Fig. 3. This disk Valve is secured to the ask by means of a screw or bolt O passing centrally through the valve and engaging the female threads of the central tapped hole a," of the plug. The valve B is provided at diametrically opposite points corresponding to the apertures a' and a2 of the plug with apertures .b' and b2, the first, b, corresponding in diameter to that of the filling-opening a3 of the plug A and the latter corresp'onding in diameter with that of the apertures a' and a2 of the plug.

Secured within the ianged disk valve B is a packing or washer D, of rubber, leather, or other suitable material, having openings d and @Z2 arranged opposite and corresponding in diameter respectively with the openings and b2 of the valve.

Projecting from the perimeter of the valve B are lugs b3 and 5*, the lower ends of which are adapted for contactv with stops E and E', secured to the fiask-mouth in such position as to arrest the movement of the valve to close or'seal the flask or to permit of a ficw of oil through one or the other of the apertures a' and a2, air meanwhile entering through the other aperture to facilitate the iiow of the oil.

The stop E is carried by one end of a spring-latch e, pivoted in such position with relation to the fiask-mouth and lug b3 and the valve that the lower end of the latch may be moved aside, (toward the lug bi) thus throwing stop E out of the path of the lug b3, whereby the valve-disk may be turned further to cause the opening b of the valve to register with the filling-opening (fof the plug.

From the construction described it will be seen that the flask may be filled by a rapid flow of oil through the large openings b of the valve and a3 of the fplug. The valve now being shifted to bring its lugs b3 and b* between the stops E and E', thespring-latch e is thrown down to raise the stop E into the path of lug 3, the latch locking in this position into a keeper a5, thus assuring the registry of the openings b and 2 of the valve and d Z2 of the gasket D with the aperturesa' and co2 of the plug A to admit the How of oil from and entrance of air into the lask or to close said apertures, thus sealing the flask.

It will be noted that the iask here described may be quickly lled Without removal of or danger of loss of a stopper or screw-plug and that all manipulations of the valve to fill a lamp are accomplished by the thumb or linger of one hand of the user resting between the lugs of the Valve, whereby the flow of oil may 'be instantly shut of in the'event of mine emergencies and other necessities.

Having thus fully described my invention, what l claim as new, and desire to secure by Letters Patent ot' the United States, 'isl. A flask comprising a body having a plug provided with apertures, and having a fixed and movable stop, a valve-disk journaled on said plug and having openings adapted to reg- GEORGE GRAHAM.
