IMPROVEMENT .IN VALVES FOR VARNISH AND OTHER CANS OR VESKSELS.

Specification forming part of Letters Patent No. 178,601, dated June 13, 1876; application filed November 12, 1875.

' To all 'whom tt may concern.-

molasses, or other materials, have been pro-V vided with a hole near the bottom, into which is screwed a gate or stop-cock. There is difiiculty, however, in transporting these vessels with the gate attached, because the latter projects and is liable to injury.

My invention relates to a peculiar construction of valve or gate, especially adapted` to being applied at the inner end of the screw-socket, so that it can be opened or closed, as required, independent of the outer faucet hence this valve will be used in shipping the can of varnish, oil, or other liquid, and partially or entirely opened after the usual faucet is screwed `to place. This becomes an additional protection against leakage or accident, and this valve can be closed when the can is being refilled, to prevent sediment passing into the outer faucet.

In the drawing, Figure l is a section of the socket and gates as ready for use. Fig. 2 is an elevation of the inner gate as open. Fig. 3 is a plan of the improved gate for the inner end of the socket.

The socket a is made with la screw-thread in the inside, and with a flange, b, upon the outside.- With metal cans or vessels this socket will be soldered permanently in place. With wooden cans or "essels this socket will be driven into place, and the inner valve or gate, when screwed to place, will clamp the wood.

ver-arm la isprovided with' an attaching pivot-stud, r, and a bearing-block, s, resting upon the surface of the face-plate e at the opposite side of the fulcrum-pivot r to the valve d, so that more or less pressure can be applied to the valve by the screw 6. The projection t, between the stops 7L h upon c, limits the swinging movement of the leverarm k', and the face-plate c is extended at one side of the opening to the thimble z' suffioiently to form a bearing for the valve d when it is turned aside from over the opening.

By this construction the valve d is free to revolve and to accommodate itself to its seat, and it cannot become misplaced, because it always rests against the at surface of the face-plate, whether open or closed.

In consequence of the valve being circular and free to turn, as it may be moved bodily aside, there is less risk than heretofore of the face of the valve becoming grooved and cut by foreign substances, because the valve will turn around if there is any obstruction to the movement of any part of its surface, and in so doing that obstruction will generally be dislodged.

The rod 7c, extending from the arm 7c to the bung-hole or top of the can, allows the valve tobe operated at any time, for the purposes aforesaid.

The tube Z and gate m are of any usual construction, and this tube Z is of a size to screw i into the socket a hence this gate l m can bc removed or attached to the socket a with facility when the gate d is closed, and this gate d is entirely out of the way, and can be opened or closed by the rod k, as occasion may require. v

This improvement gives great security in case of lire, because it will retain the contents, even if the outer faucet is broken ott'. The pressure of the liquid tends to make the inner valve or gate tight.

By closing the inner gate before refilling a can, sediment is excluded from the outer gate,

and the inner gate. can be opened after the.

foreign matters have subsided. .and by opening the inner gate more or less, the rush of liquid through the outer gate is regulated.

I claim as my inventionl. The circular revolving independent plate, forming a valve, d, having a central stem entering the cavity in the swinging stop leverarm 7c', in combination with the face-plate e, Signed by me this 10th day of November, that is sufficiently Wide to sustain the, valve A.
