SPECIFICATION forming part of Letters Patent No. 394,720, dated December 18, 1888.
Application filed July 16, 1888. Serial No. 280,135. (No model.)
To all whom it may concern:
Be it known that I, MARION PAXSON, of Virginia City, in the county of Storey and State of Nevada, have invented a new and useful Improvement in Lamp Fillers, of which the following' is a specification.
My invention is an improvement in what may be termed lamp-fillers, or devices for drawing oil from a can by siphon action; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.
In the drawings, Figure l is a perspective view of the invention as in use, parts being broken away and others shown in section. Fig. 2 is a detail view of the device the tube being partly broken away and the valve cylinder or chamber being shown in section. Fig. 3 is a detail view of the valve-tube, and Figs. l and 5 illustrate the vent formed by grooving the threads ot' the fall-pipe and the \f'alvecylinder.
The Siphon-tube A has the end of its leg A suitably formed at L to cut the hole in the can for the insertion of the leg A therein, as shown in Fig. l, while the end of the leg or t'all pipe is threaded at a', and is provided with a groove, a2, eut the depth ot' and transversely the threads o', such groove forming one half or section ot' the vent leading into the valve-chamber B. This chamber B supports the valve, and has its upper end provided with an opening, b, litted to receive the end a ot' pipe A2, such opening being l threaded internally to turn on the end of pipe A, and a `groove, h2, being formed transversely ot' the threads lr. It will be seen that the grooves u2 h2 do not exceed in depth the threads which they intersect, so that when the grooves are out ot' register the threads of the cylinder and of the pi'pe A will close the groove of the other part; but by bringing the grooves into register they together constitute a vent for admitting air into the chamber B for the purpose of causing the oil in said chamber, when the valve is closed, to innuediately discharge.
The chamber B supports the valve (i, so that the chamber is turned on threads a. It and the valve move up or down with relation to and from the open end of pipe A2, which forms the valve-seat, and thus adjusted to stop or permit the oil to iiow into the chamber, whence it passes through ports D, and thence out of nozzle E. The valve-chamber and the end of pipe A2 bear such relation that when the chamber B is adjusted to open the valve the grooves a2 b2 will be out of register, and will be adjusted into register when the valve is closed. Thus when the valve is closed the vent will be opened to admit air and permit the oil below the valve to immediately discharge.
By preference the valve-support is a tube threaded into the lower end of chamber B, and having the notches or out-out portions forming ports D, and having its lower end providing the nozzle. This construction is preferred, because it not only enables the convenient insertion and removal of the valve, but also enables the adjustment of said valve within the chamber, so as to secure the desired register of grooves a? b2 when the valve is closed.
A brace, F, is provided to support the legpipe A2 out from the cam. In operation the tube has its pipe or leg A applied to the can, the valve being closed. It will be understood that the tube should be filled with oil prior to its insertion in the can, or afterward, by suction or otherwise, if desired, when, by turning the chamber down pipe A2, the valve may be opened and oil flow out; and the flow may be shut otl' by reversing the motion of chamber B, thus closing the valve and bringing the grooves a2 b2 into register, admitting air above the oil below the valve, and permitting salue to immediately discharge, thus avoiding the necessity ot' supporting drip-cups below the nozzle.
In operation the iiller may be attached to the can and the valve opened, when, by pressing on the sides of the can, the oil may be started and caused to tlow.
Having thus described my invention, what I claim as new is l. 'lhe combination of the tube having threaded end a and groove o?, the valvechamber having threads b and groove b2, and the valve adjustably supported in the chamto pipe A2, so that the valve may be moved ber, whereby the valve and its chamber can IOO be relatively adjusted to effect an accurate l ber B into Coincidence or register, whereby coincidence or register of grooves CL2 b2 when the valve is seated, substantially as set forth.
2. The combination of the tube provided with threads CL and havinga groove, CL2, transversely of said threads, the chamber B, pro-' vided at its upper end with internal threads, b', fitted to threads CL', and having a groove, b2,
transversely of said threads b', and the valve supported in said chamber, the said grooves CL2 b2 being` movable by the turning of cham- When thevalve is seated to close the tube a vent is produced by the coincidence of said grooves to enable the immediate discharge from. the chamber of the liquid therein on the closure of the valve, all substantially as and for the purposes specified.
