BARREL-FILLER.

SPECIFICATION forming part of Letters Patent No. 388,899, dated September 4, 1888.

Application filed August 1, 1887.

To @255 whom it may concern..-

Be it known that I, LEWIS MILLER, a citizen of the United States, residing at 011 City, in the county of Venango and State of Pennsylvania, have invented a new and useful Improvement in Barrel-Fillers, of which the following is a specification.

This invention has for its object to provide means whereby the supply of liquid will be antomatica ly and effectively stopped when the barril or other reoeptahle becomes filled or contains a certain predetermined quantity.

To this end the invention consists in providing a stop cock or faucet ol'any desirable shape or size with aspring-plug, a trigger for retaining the plug in opposition to its spring in open position, a spring hamlncr for operating the trigger, a lever for retaining the hammer in set position, and a releasing mechanism consisting of means whereby the pressure of the outrushing air is at the proper time brought to bear upon and lift a diaphragm, which simultaneously communicates its movement to the end of the last-named lever, whereby the release of the hammer and tripping of the trigger follow in rapid succession, resulting in the almost simultaneous closing of the cock.

In order that my invention may be more fully understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure I is a perspective view of my apparatus, and Fig. II is a vertical section thereof. Fig. III is a detail view showing the rubber collar partly in section.

A represents the stop-cock having the cutoff D and nozzle 13. On the shell and cast integrally with it are the flanges P P, in which are formed the slots, project-ions, 8m, which support thelevers of the releasing mechanism. The plug or cut-off block D has formed on it a cylinder or drum, D, around which is wound a spiral spring, S, having one end secured to the shell at s and the other inserted in one of a series of perforations, 3 in the cylindrical drum and nutted on the inside. The cutoff block is further provided with a lever extending at right angles to its axis and preferably formed by inserting a bent rod, c, in the projection a, the latter being cast integrally with This rod ct,being curved,as reprethe block.

sented, is adapted for prehension, and when turned down in a horizontal position in oppo sition to the helical spring S is adapted to be engaged by the lower end of trigger b, which is l'ulerumed somewhat below its middle in a slot in the flange P on pin 2;, passing through the sides of said slot. The upper end of the trigger extends vertically through a horizontal plane, in which swings an arm, a, pivoted on a stud or pin, 0, inserted in the flange P, around which pin is coiled a spring, S, one end of which is seen red by a screw passed through an eye formed thereon and inserted in the shell, as at s, the other engaging the swinging arm by asmall upturned portion, 8". This swinging arm is adapted to be held back in opposition to its spring some distance from the trigger-lever by a projection, c", on its end, which engages the L-shaped projection cl on the ro clrlever d,

which is fulcrumed at d, and has its other end projecting forward and downward,terminating at apoint above the vertical piston-rod e, which is adapted to lift it by an adjusting-screw, R. the end of which rests on the square head e of said piston rod c. This lifting-rod works in a tubular portion of a casing or housing, E, the lower part of which is hemispherical and secured by screws down onto a bracket, B, cast integrally with the nozzle and clamping between its periphery and the bracket aflexible diaphragm, e, to which the lifting-rod is secured by two nuts impinging on opposite sides thereof, the rod being inserted through the center of thediaphragm.

Cast in the nozzle is a small channel,k,which communicates with the under side of the diaphragm by means of a recess, 7a. The other end of this channel communicates with the inside of the barrel when the apparatus is inserted. There is also cast in the nozzle a passage of considerably larger capacity than the one is, and in this is inserted a tube, H, movable vertically and adapted to be secured at any height by a clamp, G, held by a screw, g, working in a slot in said clamp.

The nozzle Bis made frusto-conical,with its lower portion cylindrical, or it may be made cylindrical and have a tapering rubber collar extending downabout half its length, as at B. The cylindrical portion is slightly cut away near its lower portion to allow the free and uninterrupted operation of a float, h, fulcrumed to an arm, h, on the tube H, and adapted to be lifted by the liquid to close the opening of the pipe H, which serves as the main outlet for air, and it also allows free access to the opening of the small air-passage.

M is the passage for oil or other liquids with which the vessel is to be filled, and it passes through the cock and down through the nozzle in the usual way. The plug or cut-off block D has passage N through'it which is adapted to be closed by a quarter-revolution of the block D, caused by the spring S when the lever of said block is released from engagement with trigger I).

z is a small portion of the nozzle not cut away, which serves as a shield for the tube and float. The two latter may freely pass down through the semicircular opening made by the piece 2.

In securing the handle to the shell I prefer to dovetail the ends of the bail and slide them down between the bevel-faces of two projecting lips, l 1, formed on the shell. I then insert a screw, 2, whiohsecures it against vertical or other movement. Acushion, p, is provided for the lever a of the cut-off block, against which it strikes when forced around. This is preferably done byinsertingin ahole in the projection p a small block of rubber, p. The stop-cock is screw-threaded at T for attachment to any pipe.

From the above description of the construction and arrangement of parts it will be readily seen that as the nozzle of the apparatus is inserted in the bung-hole an air-tight joint is made,and the apparatus being set to allow the liquid to flow in the displaced air must escape through pipe H. "When, however, the liquid reaches a height such as to float the slopper h, the same closes the opening of the pipe H, the exit ofairis immediately stopped, and a pressure developed within the vessel which is simultaneously communicated to the under side of the diaphragm. The piston rod rises, lifts the end of the rock-lever, thus releasing the swinging arm, which in turn strikes and rocks the trigger, whereby the block-lever is disengaged and the cut-off block allowed to revolve by the force of its spring, and thus cut off the flow of oil. The operation of all the parts is almost simultaneous and takes place immediately the oil reaches a certain height, so that a great quantity of oil otherwise wasted is saved by shutting off the supply at the proper time.

By raising or lowering the main outlet-pipe the float will be raised sooner or later and the quantity of oillet in will be greater or less, as will be clearly seen.

I prefer to cast the shell with the flanges and nozzle in one piece; but I do not wish to limit myself to this method of forming the same, as it will readily be seen that the shell may be cast in two pieces and joined in any suitable manner by having the division come' in the flange P and the two meeting faces secured together in any preferred manner.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a barrel-tiller, the combination, with the shell A, having nozzle B, with bracket B, handle 0, and flanges P P, of spring plug D, spring S, and lever a a, trigger b, swinging arm 0, operated by spring S, lever d,engaging with lever c,lifting-rod e',secured to diaphragm 0, housing E, said nozzle having air-passage is, leading to said diaphragm, and verticallyadjustable tube H, all arranged as shown and described.

2. The combination, with an automatic stopcock adapted to be set in operation by airpressure on a diaphragm, of a nozzle for insertion in a bung-hole, a vertically-movable tube for escape of air, a smaller channel through which air-pressure is communicated to the diaphragm when the outlet is closed,

and a clamp, G, for holding the outlet-tube at a higher or lower position, for the purpose set forth.

3. The combination,with an automatic stop,

cock adapted to be set in operation by airpressure on a diaphragm, of a nozzle for insertion in a bung-hole having an air-outlet tube vertically movable therein and a channel through which air-pressure is communicated to the diaphragm when the outlet is closed, for the purpose set forth.

4. The combination,with an automatic barrel-filler, substantially as described, having a nozzle for filling a bung-hole, of a verticallyadjustable tube making air-tight connection with the nozzle and having a projection, It, on which is fulcrumed a float, h, adapted to close the said tube, whereby escape of air from the vessel is prevented.
