- To all whom it may concern:

Be it known that I, ISAAC E. SExToN, a citizen of the United States, and resident of West Medford, in the county of Mld'dlesex and State of Massachusetts, have invented certain new and useful Improvements in Cans for Gasolene, '&c., of whlch the fol lowing is a specification.

This invention relates to a can for storing volatile liquids such as gasolene, the can being provided with a neckthroughwhlch it may be filled and emptied, said neck having I a valve seat and the can being provided with a valve yieldingly held by spring'press'ure on said seat.

The invention has for 1ts ob]ect to enable the valve tobe easily displaced, to permitemptying and filling of the can, against the pressure of a relatively strong springwhich normally holds the .valve seated and prevents leakage of gas and liquid under ordinary conditions, the valve being at the same time adapted to yield and act as a safety valve in case of high pressure within the can.

The invention also has for its object to enable the valve to be accurately guided to its seat when released from a displaced position. The invention consists in the improvements which I will now proceed to describe and claim.

Ofthe accompanying drawings forming a part of this specificationzFigure 1 represents a vertical sectional view of a can embodying my invention; .Fig. 2 represents a Section on line 22 of Fig. 1; Fig. 3 represents a side view of a portion of the can illustrating the operation of manually displacing the valve.

The same reference characters indicate the same or similar parts in all the views. In the drawings,- 12 represents a can,

which may be of any suitable form and construction, the can being usually made of sheet metal. v

13 represents the neck through which the can is filled and emptied, said neck being preferably a relatively thick metal tube suitably Secured to the breast of the can and projecting above the same, the upper end of the neck forming an annular valve seat 14.

The neck is normally closed by. a valve held upon the valve seat by a spring 15 located I sible material such as leather.

projecting boss 20 which occupies the .central opening of the gasket. The"base of the.-

taperin or conical inner member is seated" on the 'oss 20 and bearsion the under Side of the gasket 18, the gasket being clamped I between said members. The diameter. of

said base is less than that. of thegasket, so that the marginal portion'pf thegasketis exposed at its under side and bears on the" valve seat 14, as indicated by Fig. 1. The

two members of the valve body are connected by a bolt 22, the'inner end portion of which is screw-threaded and engaged with a tapped orifice in the 'inner.member 17. Said bolt is utilized to secure to the valve body a. handle 23, which is preferably elliptical, as shown by F ig.- 1,a1id provided in its lower portion with an orifice, the wall of which loosely surrounds the bolt 22.

The handle is held loosely against the Valve-body by the head 24 of the bolt, and

is therefore swiveled to turn on a vertical.

center, so that its major "axis may beturned to a position parallel with the handle 38 hereinafter described, without turning the valve, and therefore without turning or twisting the Spring 15 and varying the tension of the'latter.

' On the inner end or apex of the inner member 17.is formed an ear 25 which is The upper end of the spring bears on a fixedannular abutment 30, which is a ring provided with ears 31 connected by rivets 32 with a foraminous safety tube 33 rigidly attached by solder or otherwise at its upper end to the neck 13 and extending therefrom practically to the bottom of the can. The

tube 33 is preferably reinforced by longitudinal strips 34 soldered thereto, the strips being located at opposite sides of the tube and receiving the rivets 32, as indicated by Fig. 2.

The head 28 and disk or washer 29 consti tute a spring support located within the than the rod, so that the rod may be freely tube 33. The rod 27 is I laterally unob -i structed above said support, the annular abutment being of much larger diameter tipped laterally in any direction to bring its upper end against one side of the neck 13, as shown by Fig. 3.

The spring 15 1s confined laterally by a a tubular guide 35, the upper end of which is 'crum. The described connection between soldered to the fixed abutment 30. The handle 23 is formed to be engaged by the fingers of one hand of the operator, so that the valve-may be lifted from its seat against the force of the spring 15. The said-handleand the valve body including'the inner member 17 constitute a lever adapted'to be fulcrumed on the valve seat 14 when the valve is displaced laterally after being lifted from its seat, as indicated by Fig. 3. The operator is thereforeenabled to utilize the valve as a. spring compressing lever, by first slightly lifting the valvebya direct upward pull, and then tipping the valve to one side of the neck while the inner member 17 bears on the valve seat,'whieh acts as a fulthe handle 23 and the valve body prevents the handle from tipping relatively .to' the valve body, sothat the said lever cannot buckle, but is practically rigid from the when the lever is manipulated as shown by Fig. 3. The muscular force required, to

displace the valve and hold it displaced so that the neck is practically unobstructed, is therefore reduced to the minimum. The conical inner member 17 being rigid is not indented by contact with the seat 14, and is adapted to slide on said seat with the miniby Fig. 1, and by dotted lines in Fig. 3, so

mum of friction-a1 resistance and wear.

I prefer to provide the'can with a bail 36 hinged to cars 37 on the breast of the can, and provided with a handle 38. The form and arrangement of the bail and its handle are such that the handle 38 may be located directly over the valve handle 23, as shown that the palm f the operators hand may bear on the han le 38 while the fingers,'partially straightened, engage the valve handle as indicated by dotted lines. The valve may now be lifted from its seat by inward flexure'of the fingers, and the bail and valve may then be swung to the full line position shown by Fig. 3, the valve being displaced and the spring 15 held in a compressed condition. When the handle 23 is released the l ear 25 to the outer portion ofthe handle 23 v escape? The bail 36'and its handle as when held as shown lay-dotted lines (Fig. 3) enable the operator to hold the can down upon a floor while lifting the valve from its seat. 'When the partially lifted valve is moved sidewise to cause the .inner member to, bear on the valve seat, and while it is being moved to the full line position (Fig.3), the downward pressure of the inner member against thevalve seat continues to hold down the can. It will beseen thereforethat provision is made for preventing the can from being lifted with the valve. In" other words, provision. is made for holdingdown the can gwhile the valve is belng lifted and displaced against the force of'the spring. A spring sufliciently powerful to normally maintain a gas and liquid-tight pressure of the valve against its seat may therefore be employed,

without rendering the lifting. and displacement of the; valve diffioult and inconvenient. The lower *end of the tubular guide 35 is preferably provided. withja foraminoushead or cap 35 ()wingto the fact that the spring 15 is located wholly above the lower end of the tube 33, the length of the spring bottompof the can.
