VALVE.

SPECIFICATION forming' part of Letters Patent No. 702,417, dated J' une 17, 1902.

Application tied April 6, 1901.

10 (tu tuff/O77?. it' mot-y concern:

Be it known that we, WILLIAM GATES, residing at Woodbridge, and Louis WILLIAM GATES, residing at Orange, in the county of New Haven and State of Connecticut, citizens of the United States,`have invented certain new and usefullmprovements in Valves, of which the following is a specification.

This invention relates to appliances adaptlo ed for use in drawing off liquids from containing vessels, and more particularly to straightway-valves designed for use in drawing olf lager, ale, and the like from casks, kegs, or barrels.

In dispensing beer, ale, the., to the consumer it is a common practice to effect the discharge of the liquid through a valve-controlled passage communicating with the keg, cask, or other` vessel in which it is stored through the tension exerted by carbonio-acid gas, air, &c., admitted under pressure to the vessel and serving to elevate ythe liquid through a pipe extending some distance below the surface of the liquid.

The present invention has for an object to provide an appliance simple in form and of cheap construction whereby access may be had to the interior of the keg, &c., for the insertion of the pipe or conduit through which the liquid is to be discharged; and theinvention provides, furthermore, an appliance that may be permanently secured to the keg and has no projecting parts liable to breakage or injury during transportation. y

Referring to the drawings which accom; pany the present specification and whichillustrate an embodiment of our invention, Figure lis partly an elevational and `partly a sectional view representing in place an ap- 4o pliance of theL foregoing character constructed according to our invention. Fig. 2 is a longitudinal section thereof on a somewhatenlarged scale and shows in connection with the valve proper and variousparts a key for 45 operating the former. Fig. 3 is a top View of the appliance, the key shown in Fig. 2 being removed and the passage through the former being open. Fig. 4t is an elevational view of a certain valve-actuator embodied in the im- 5o provement. Fig. 5 is an end view thereof.

shown in Fig. 4. and the valve-casing of the appliance with certain of its parts. Fig. 7is an elevational view of the valve-casing with the guard-piece shown in Fig. 5 in the position it occupies when the opening through the appliance is closed. Fig. 8 is a perspective view of a sliding plate embodied in the appliance and constitutingthe valve proper. Fig. 9 is a similar view of the valve-casing. Fig. 10 is a similar View of the Aguard-piece. Fig. 1l is an elevational view of a key adapted for openingand closing the passage way through the appliance. y

Similar characters of reference designate corresponding parts in all figures.

An appliance constructed according to the present invention is particularly adapted for permanent attachment to a cask, keg, or other vessel used for holding beer, ale, and otherbeverages, and its construction embodies no projecting parts liable to injury or damage during handling or transportation, providing, furthermore, a straightway` opening into the keg, dac., through `which the discharge-pipe for emptying the former may be inserted. Means also exist for the attachment of a conduit or pipe delivering carbonio-acid gas, air, or other fluid utilized for exerting a pressure upon the liquid within for the purpose of elevating the saine through the inserted pipe.

The appliance is shown in Fig. l of the present drawings secured to the head of a keg A of liquor, and it comprises a tubular body portion (designated in a general wayby B) adapted to be secured in a suitable opening in the vessel in any desired manner, the connection here shown comprising a screw-thread b on the outer` surface of the bodyportion, by which means the latter is adapted to be screwed into the vessel until it abuts against a shoulder b', formed by a flange on the body portion and preferably entering a countersunk recess to bring the outer-face of the body portion substantially flush `with the outer surface of the head, as indicated in Figs. l and 2.

The valve proper of the appliance serves to control the continuity of the passage through the bore of the body-piece and in the preferred construction is mounted in a valvecasing, which may be attached inany desired way to the body portion of the appliance, the provision of an independent valve-casing facilitating the manufacture and assembling of the parts. The valve proper (designated in a general Way by C) is conveniently made in the form of a sliding plate, which is adapted to move transversely to the passage through the bodyportion, being mounted in a suitable guidevvay 2, formed in the valve-casing, (designated in a general Way herein by D.) The guideway in the valve-casing as formed in the present instance is a T-slot at the lower portion of the casing, the sliding plate constituting the valve having a rib 3, forming one its guiding-surfaces. The sliding plate may beheld against its seat to form a sliding joint by some spring-like device, this device as constructed in the present case comprising springs 4 and 4, inserted between the sliding plate and overlapping portions of the guideway formed in the valve-casing.

For operating the valve We provide avalveactuator conveniently consisting of an oscillatory member which serves to transmit motion from the operating-key (to be described) to the valve-plate and effect the movement of the lat-ter in its guide. In the form herein shown this actuator (designated in a general Way by E) comprises an annular part 5, Whose central opening forms part of the passage through the appliance. The actuator is mounted to rotate upon its axis in the valvecasiug, being confined to its proper movement according to the illustrated construction by bearing portions 6, (any suitable number,) formed in the valve-casing, a circular flange 6 within the body portion, and the inner surface of the valve-casing. Projecting from the annular part of the actuator is a pin 7, which enters a recess 7 in the sliding or valve plate and serves to effect the movement of this valve plate when the actuator is turned upon its axis, an elongated opening 8 being provided in the valve-casing to permit of the movement of the projecting pin and having shoulders at its ends determining the extent of movement of the latter. Afriction device for preventing too free a movement of the actuator is shown, consisting of a spring 9, Whose curved end isadapted to bear against the periphery of the actuator.

A key fol-shifting the valve-plate is adapted to pass down through the bore of the body portion' and engage with the valve-actuator. The construction for effecting this engagement comprises in the present embodiment projections 1111, (two such being shoWn,) cX- tending from the actuator axial/ly of the bore of the body portion and adapted to engage with corresponding notches 11'11", formed at the end of the key F. The key is hollow or tubular, and from the foregoing description it is evident that When inserted in place and turned upon its axis the resulting movement of the actuator Will effect the shifting of the valve-plate.

The key serves as a convenient means for the inlet of the pressure medium, and for this purpose it is provided with a tubular oiset 12, to which a conduit 13, delivering the pressure medium, may be attached.

Through the tubular key when turned to a position in Which the valve-plate is opened and through the body and valve portions of the appliance may be passed the pipe or conduit (designated in a general way by G) serving for the discharge of the containing liquid and which terminates adjacent to the bottom of the vessel. This discharge-pipe Gis somewhat smaller in diameter than the diameter of the straightway passage to admit the pressure medium to the interior of the vessel, and for the purpose of making a tight joint With the body-piece to prevent a leakage outward around the key there is provided suitable packing 111 anda coperating seat 14 therefor. i This packing may be pressed securely against the seat by providing inclined or camshaped ears 15 15 on the key, which as the latter is insertedin place pass through corresponding recesses 15 and 15"', respectively, in the body portion and serve by their coaction with coperative portions 154 155, respectively formed by circular slots in the body portion, to press the packing firmly against its seat. This construction also locks the key in place until it has been turned back to its entering position-that is, to a position corresponding to a closed position of the valve-plate-and if the ears and corresponding recesses are made of different Widths pair and pair, as shown, Will permit the insertion of the key in a definite position only of the latter.

The tubular key is furnished at its upper or'outer portion with a suitable means for connecting it by a pressure-tight joint with the discharge-tube G. For instance, it may be connected to the latter by a coupling 16, and the outer delivery-tube g for delivering the liquid to the desired point may be connected directly With it, or the discharge-tube may be provided with an attached valve 17 and a coupling (designated by 1S) utilized for secu ring the delivery-tube g to this valve 17.

To .prevent the forcible insertion of a discharge-pipe through the appliance With probable resultant injury to the valve-plate when the latter is in a closed posit-ion, there is provided in the present embodiment a guardpiece, (designated in a general Way by H,) Which consists of a linger provided With a pivot-pin 20, entering a pivotal recess in the valve-casing and adapted to pass through an opening 21 in the annular portion of the valveactuator. It will be noticed, particularly in Fig. 7, that the shoulders at the ends of this recess are somewhat curved, constituting thus a means for securing the operation of the guard piece. When the valve-actuator is turned to a position in which the valve-plate is closed, the shoulder 22, impinging against the side of the guard-piece, urges the same into a position in which it extends across the passage through the appliance. When, how- IOO IIO

ever, the actuator is rotated to shift the valveplate and open the passage, the opposite shoulder operating in like manner serves to Withdraw the guard-piece from its protruding position across the passage; but the parts are so constructed and related that the shoulder 22 does not assume a position in which the guard-piece is permitted to be withdrawn from its protruding position until the valveplate has been moved to substantially the end of its opening movement. Thus it will be seen that the guard-piece, which, it may be stated, is located in a different' plane to that which the valve-plate occupies, serves to protect thelatter in all positions in which it extends into and across the passage.

The valve-plate is shown provided with a concave notch 23 at one end,iwhich notch is brought into alinement with the throughpassage When this plate is shifted to open the passage.
