SPECIFICATION forming part 0f Letters Patent NO. 476,167, dated May 31, 1892.

Application iiled June 3,1891. Serial No. 394,987- (No model.)

To raf/ZZ whom it may concern:

Be it known that I, HARVEY S. PARK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Beer-Cocks; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, forminga part hereof, in which- Figure l is a central longitudinal section. Fig. 2 is a cross-section through the valvechamber. Fig. 3 is a face View of the valve with the valve-stem in section. Fig. et is a detail of the cover for closing the dischargeopenlng.

The objects of this invention are to improve the construction and operation of been cocks, more especially in reference to the valve for opening and closing the discharge, by giving the valve a positive seat when closed,to prevent the escape of gas, and to prevent the admission of dirt, dust, and insects into the discharge-opening, and have the means for closing the discharge-opening actuated with the movement for closing the valve, and to improve generally the construction and operation of the cock as a whole; and its nature consists in the several parts and combinations of parts hereinafter described, and pointed out in the claims as new.

In the drawings, A represents the entering end of the cock, which may be formed tapering with a smooth exterior, as shown, or the exterior can be provided with a screw-thread.

B is the body or stem of the cock, through which and the end A is a passage a, and this passage, as shown, is lined or coated with tin b.

C is the driving-head for forcing the cock into place.

D is a wall inclosing the valve-chamber.

The parts A B CD can all be cast or formed in a single piece, as shown, or they could be formed of separate pieces screw-threaded or otherwise irrnly united one to the other to form in effect a continuous or single piece.

E is the valve-chamber, into which, on one side, the opening c leads, which chamber is formed in the wall D and is open on one side for the insertion of the valve, and the ,opening, as shown, is tightly closed by a screwthreaded plug E.

F is the Valve, formed of an annular disk, with a fiat acting face, and having a central hub e', with a square opening g. The disk portion of the valve has a port c through it, which port can be brought into line with the discharge-opening f in the Wall D, and, as shown, between the face of the valve and the face of the wall D is a gasket c to insure a tight closing of the valve and escape of the gas, and this gasket has therein an opening corresponding to and in line with the opening fin the wall D. The valve F is forced and held firmly to its seat by the pressure of the gas; but in order to insure the seating of the valve under all circumstances a coiled spring CZ is located between the valve F and the plug E', one end of the spring encircling the hub or center e of the valve and the other end entering a recess CZ in the plug E.

G is a stem inserted in the wall D and having at its inner end a square portion c, fitting the square opening g and connecting the valve to the stem, so that with the turning of the stem G the valve will be turned, and, as shown, the stem G is held against outward movement by a iiange g on the stem G.

H is a bar having at its outer end a handle H and attached at its inner end firmly to the stem G, by means ot which bar and handle the stem can be turned.

I is a cap or cover for closing` the mouth of the opening f, which cap or cover has an ear c, receiving a screw h', the body of which passes through a slot 7i in the bar H, so that by loosening the screw h the cap or cover I can be adjusted on the bar I-I, so as to fit against the face of the wall D and tightly close the mouth of the openingf against the admission of dust, dirt, and insects, and, as shown, the limit of the movement of the cap or cover I in closing the mouth ot the opening f is had by a stop i on the wall D, as shown in Fig. 2.

1 The valve is located in the body or stem of the cock by inserting the stem G in the hole therefor in the wall D, then placiu g the gasket cfor use around the projecting inner end of the stem and against the face of the Wall D in the chamber E, then slipping the valve F on the end g of the stem G in the chamber E,

IOO

then placing the spring CZ in position around the hub or center c', and closing the chamber E bv inserting the plug E', and the valve is completed ready for use by attaching the bar H, with the handle II', onto the outer end of the stem G, and when the bar H is attached the cap or cover I is placed in position on the bar H and adjusted on the bar, so as to properly coact with the face of the wall D, and then locked by the screw 7L.

The operation is as follows: The end A is forced or driven into the barrel or other receptacle with which the cock is to be used by 'striking blows on the driving-head C, and

when inserted the cock is ready for use, and in use to draw the beeror other fluid the handle l-l is raised, raising` the bar H and turning the stem G, which turns the valve F, and when the bar Il strikes the drivin g-head C the opening e in the valve F will have been carried around to be in line with the openingf, and at the same time the cap or cover I is carried,witl1 the bar H, from beneath the mouth of the opening f, which brings the parts into position for the beer to pass through the opening a into the chamber E,and thence through the port e into the passage or opening f to be discharged therefrom,and when the required quantity has been drawn the handle H is turned down, carrying with it the bar H, reversing the rotation of the stem G, and carrying the valve F around with the stem for the port e to pass out of communication wit-h the opening or passage f,and at the same time the cap or cover I is carried down t0 movement in this direction is had by the edge of the cap or cover I striking the stop i.

It will be seen that the movement of the valve f to open communication with the passage or opening f and the movement of the cap or cover to unclose the mouth of the passage or openingf are in unison, and when the port e is in communication with the opening or passage f the cap or cover I is entirely away from the mouth of the opening or passagef, and by having the bar II engage the driving-head C when the port e is in communication with the opening or passage f the operator knows that communication is established, and by having the stopt' engage the edge of the cap or cover I a positive stop for the cap or cover beneath the mouth of the opening or passage f is had for closing such mouth or passage. The travel of the port ein relation to the opening or passage f and to the travel of the cap or cover I is one by which the port e will pass out of line with the opening or passagef before the cap or cover I comes into position to close the opening or passage f, and by this means the valve E closes the opening or passage f against discharge before the opening or passage f is closed by the cap or cover, thereby allowing the opening or passage f to drip and become clear of the beer before it is closed by the cap or cover.

The cap or cover prevents when underneath the mouth of the opening or passage f the entrance of dirt, dust, or insects into such passage, and such cap or cover is brought into position to perform its ofice with the movement of the valve F in shutting ott communication through the port e, so that with the closing or shutting off of communication through the valveF the cap or cover is brought into position to shut ott or close up the mouth of the opening or passage f.

The lining of the passage a in the stem of the cock with tin prevents gas from affecting' the stem when made of brass or other material, and thereby injuring the beer, and as a further preventive against the action of gas the interior of the chamber E can be lined with tin and the valve F be made wholly of tin or faced with tin and the spring d covered with tin, and in actual use the acting face of the valve can be made to seat direct against the face of the wall D, thereby dispensing with the gasket c but by using the ing faces.

Vhat I claim as new, and desire to secure by Letters Patent, is.-

1. The combination, in a beer-cock, of a valve-chamber having on one end a seatingface for a valve, a discharge-passage at the lower side of the valve-chamber, a disk valve in the valve-chamber seating against the face of the chamber and controlling the dischargepassage, an outside cap or cover traveling in the arc of a circle and turning with the valve, opening and closing the mouth of the discharge-passage, and a port in the valve traveling in the arc of a circle, opening and closing the discharge-passage, said port and the cap or coverboth having the samelimit of travel on opposite sides of a common center on which they turn, the limit of down travel of the port opening the discharge-passage with the cap or cover at the limit of its up travel and the commencement of the down travel of the cap from the discharge-passage, giving the cap or cover the travel from the limit of its upward travel down before closing the mouth of the discharge, thereby -escaping the drip after the port is closed, substantially as and for the purposes specified.

2. The combination, in a beer-cock, of a wall, a valve-chamber in the wall having on one end a valve-seating face, a discharge-passage from the lower side of the valve-chamber, a disk valve in the valvechamber seating against the end face of the chamber, a port in the valve traveling in the arc of a circle and establishing communication between the valve-chamber and the discharge-passage at the limit of its down travel, a stem carrying the valve, a bar operating the stem, and a cap or cover on the bar traveling in the arc of a circle over a coacting face of the wall around the mouth of the discharge-passage,
