SPECIFICATION forming part of Letters Patent No. 487,674, dated December 6, 1892.
Application filed October 1, 1891. Serial No. 407,445. (No model.)
To all whom it may concern.-
Be it known that I, HIRAM S. JOHNSON, a citizen of the United States, residing at Oanaan Four Corners, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Lock-Valve Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to lock-valve faucets for use with vessels containing gaseous or fermented liquids; and it consists in the combinations of devices and parts hereinafter described, and specifically set forth in the claims.
The objects of my invention are, first, to provide a water and gas tight valve which maybe readily applied to a keg, cask, or other Vessel; second, to combine with such water and gas tight valve a key which is removable at will and serves as a means for opening and closing said valve and also as a conduit for the liquid while being drawn, and, further, to provide particular combinations of devices and parts by which my improvements in this invention may be embodied in faucets. I attain these objects by the means illustrated in the accompanying drawings, forminga part of this specification,in which Figure 1 is a longitudinal sectional View of a faucet embodying the improvements in my invention. Fig. 2 is a longitudinal sectional view of the body of the faucet. Fig. 3 is a front-end View of the same. Fig. 4. is a rearend view of the same. Fig. 5 is a sectional view of the liquor-straining piece. Fig. 6 is a view of the same from its front end. Fig. 7 is a sectional view of the valve. Fig. 8 is a front-end view of the same. Fig. 9 is a rearend view of the same. Fig. 10 is a sectional view of the key. Fig. 11 is a view of the same from its front end. Fig. 12 is a View of the same from its rear end. Fig. 13 is a sectional View of the follower of the key. Fig. 14. is a rear-side view of the same. Fig. 15 is a side elevation of clamping-hooks used with the follower. Fig. 16 is a view of one of said clamping-hooks from its head end. Fig. 17 is a view of the other from its head end.
The same letters of reference refer to similar parts throughout the several views.
In the drawings, A is the body of the fancet, which body is made tapering and is provided with a screw-thread when it is to be used with awooden vessel. A is the central bore of the same, which bore receives the key employed for opening and closing the valve of this faucet. A is an internal annular recess made in the rear-end port-ion of said body and provided with the internal screw-thread a for receiving and holding the valve and liquorstraining piece.
B is the liquid-straining piece, which closes the rear or inner end of the body A of the faucet. This piece B is made with a diameter of body and a screw-thread b which correspond with the diameter and screw-thread a of the recess A and has a flange-form head Z) for seating tight against the end edge of the rear end of the faucet A. B is a chamber made in said piece B from its inner side, and b is a ring-form recess at the bottom of the said chamber, which recess may in some cases be dispensed with, if preferred. The back wall of this piece B is provided with a series of small perforations v v on a line outside of the circumferential line of the ringform recess b O is the valve, made of any suitable material and with a tubular form and provided with the external screw-thread c, of diameter and size corresponding with the internal screw-thread a of the annular recess A of the faucet, so as to nicely work in the same. This valve is provided with the plain plug portion 0', of diametercorresponding with that of the chamber 13 of the liquid-straining piece B, and is provided with the ring-form lip 0 projected rearwardly from the rear end of the said plug portion cof this valve, which ring-form lip is to nicely lit with a gas-tight joint with the bottom of the liquid-straining piece or bottom of the recess 17 when made in the bottom of said piece. This valve-piece has through it the central perforation O, and annular to said central perforation is the ringform recess 0 made in said valve from its forward end. When this valve-piece C and the liquid-straining piece B are both in place in the faucet A, there isprovision for anendwise movement of said valve-piece between the inside end of said straining-piece B and the shoulder a at the forward terminal of the internal screw-thread a of the body A of the faucet. \Vhen the valve G is revolved in one direction, it will he carried rearwardly by the coacting screw-threads a and 0 toward the bottom of the chamber B of the liquidstraining piece B, with the edge of the ringform lip c seated tightagainst the bottom of the said straining-piece or that of the ring form recess 11 when provided in said piece B, and all communication of the ports or perforations b b in the straining-piece B with the central perforation C of the valve will be closed. A reversed revolution of said valve operates to reverse the movement of said valve and carry the sealing-lip c of the same away from the bottom of the straining-piece B or the bottom of the recess 1) in the same, and thereby open communication from the ports or perforations "u 'u of the straining-piece B and the central bore 0 of the valve. This valve-piece 0 may be operated by different means for giving it an end wise movement, as above described; yet I give preference to the use of a removable key, which will also serve as a conduit for the liquor drawn through this faucet, and with the use of such a removable key D there are provided in the bottom of the recess 0 in the front end portion of the valve 0 one or more indentations w w or sunken or projected holding devices for engagement with a coacting projection 06 w or an indentation provided with the said key; yet preference is given to the employment of indentations or sub-recesses as w made in the bottom of the ring-form recess 0 as shown in Figs. 1, 7, and 8.
D is the key by which the valve 0 may be operated for opening and closing the faucet. It also serves as a conduit for the liquids drawn from the same. This key is of a tubular form and has an unobstructed central bore (1, which leads from the chamber B of the strainingpiece B to a discharge when the valve 0 is open. lVhen this key is to be removable, it may be held with the body of the faucet by any suitable means which may render it detachable at will from the latter. My preferred means for securing the said key with the body of the faucet is shown in the drawings. In this preferred means the body A of the faucet has made integral with it the flange A at its outer end. This flange has in it two or more notches a a sunken in its margin edge portion toa depth of one quarterof one inch, more or less, and preferably made with a dovetail form, that of a being made with a spread at the outer edge, while a is more contracted, so that these notches will be of reversed forms, as shown in Fig. 4..
The key D has integral with it the flangecollar D, in which collar or extension D D of the same are provided squared perforations d d at points which will register with the dovetail notches a a made in the flange A of the bodyAof the faucet. In the outer side of the said flange-collar D is the ringform groove 01 for receiving one end of the spiral spring S.
E is a follower having its central perforation a of diameter corresponding with that of the body of the key D forward of its flangecollar D. This follower has in it the ringform groove 6, corresponding with the groove (1 in flangecollar D, for receiving the opposite end of spring S, and also has in it perforations e 9 which register with perforations (1 d in flange-collar D. The spring S is held between the said flange-collar D and the follower E by the grooves 61 and e, respectively, in the same, and, while it operates to crowd the latter away from the former, its elasticity will allow the follower to be drawn tight to said flange collar.
F F are clamping-hooks having their hookheadsf made, respectively, with forms corresponding with those of the respective dovetail notches at a in the flange A of the faucet. The stems of these clamping-hooks back of the said hook-heads fare made square and of size corresponding with the squared perforations 01 d in the flange-collar D of the key D. The tail ends of these clamping-hooks are secured by any suitable means to the follower E, and preferably by riveting, after being entered into the perforations e e in said follower.
In some cases the screw-thread a of the rear end recess A of the body A of the faucet may be extended from shoulder a only to the inner end of the liquidstraining piece B, while the rearward portion of said screw-thread (1 (shown in the drawings, Fig. 1, as receiving the screw-th read I) of said straining-piece) may be omitted and the periphery of said straining-piece be enlarged and made plain to nicely fit such plain rearward portion of said recess, when the said straining-piece may be secured in place by keying, riveting, or soldering or other suitable means.
When the valve-piece C and the liquid straining piece B are both in place in the recess A, their united lengths of cylindrical portions at the wall of said recess will be of less extension than that of the recess from shoulder a to the flange-head b, so as to produce a chamber m between said shoulder a and end edge I) of the straining-piece B, in which chamber m the larger and screw-threaded portion of the valve-piece C may be moved longitudinally in either direction. A chamber 01 is also provided between the rear end of the plug portion 0 of the valve-piece and the rearwardly-projected ring-form lip c and straining piece B, and with this chamber a the ports 1; o communicate from the outside ofsaid straining-piece. When the valve-piece C is in position shown by full lines in Fig. 1, the ring-form lip 0 will be out of contact with the bottom of the recess b of the strainingpiece, so that the liquid passing through the IIO ports 1) i; into chamber n may readily enter the chamber at between the bottom of the straining-piece B and the adjoining end of the tubular key D, and thence have passage through the bore of the latter to a suitable discharge therefrom; but when the said valvepiece 0 is in position away from the shoulder a of the recess A to the full distance it is allowed to move, and so that the rear end of its ring-form lip c is seated tight against the bottom of the recess of said straining-piece the valve will be closed and escape of liquids from the vessel (not shown) through the ports 12 c and thence into the chambers 71 n and to a discharge through the tubular key will be prevented. This opening and closing of the valve by the longitudinal movement of the valve-piece O is effected by revolving the said valve-piece in a suitable direction so that the screw-threads a of the recess A and c of the valve-piece C may coact to move the latter longitudinally in either direction required for those purposes. When the valve-piece O is to be closed against the bottom of the straining-piece B, the former will be revolved, say, to the right, and for moving it away from the same the valve-piece will be revolved in the reverse direction. Any suitable means may be employed for so revolving said valvepiece, yet preference is given to the employment of the holding devices w a: in said valvepiece and their engaging devices 00 ac, (shown to be provided at the rear end portion of the key D and projected rearwardly from the shoulder 61 of the reduced cylindrical portion D which works in the central perforation O of said valve-piece.) The forward or outer end of the key D is provided with a screwthread (1 for coupling with said key a faucet (not shown) of any suitable form of construction or a pipe or hose or other device for controlling or leading the liquid being drawn to a suitable place of discharge.
The manner in which the several parts of this improved faucet operate is as follows: The body A of the faucet has secured in place in it the valve-piece C and the liquid-straining piece B, with the former tightly seated against the latter, so that all communication from without the, faucet through ports 1) o with chamber 12. will be stopped. This faucet-body A is then securedin place in the vessel with which this improved faucet is to be employed, and when the vessel is of wood it may be secured by screwing it into the same before or after filling the vessel, and the liquid within will be held from escaping by the way of the faucet until the valve 0 has been moved away from the straining-piece B, so that the ports 0 1; will have an uninterrupted communication with the chamber n. When the liquid is to be drawn from the vessel (not shown) this faucet is so applied to, the key D will be inserted in place in the fancet-body A and be secured therewith by a suitable coupling device or the follower E, clamping-hooks F F, and spring S respectively secured in place with said key and the flange A of the faucet-body, as shown. This is done by inserting the rearward portion of the tubular key D into the bore of the faucet A to its full distance, so that its holding devices an 00 will engage with the holding devices x m of the valve-piece O, with the heads ff of the respective clamping-hooks F F passed through the dovetail-form openings a a with which they respectively correspond, when the key may be turned slightly in either direction, so as to carry the said heads fof said hooks into engagement with the rear side of the flange A of the faucet-body A, when said key will be locked in place with the same and be ready to be operated at will for opening and closing the valve. \Vhen the key is locked in place with flange A there will be a small space between the said flange and the flange-collar D of the key, which will allow the key to be turned in either direction and also give to the clamping-hooks an elastic holding with the faucet. The reversed order of the forms of the hook-heads f f of the clamping-hooks F F coact with the reversed dovetail notches a a in the flange A of the faucet-body to allow each of said hook-heads to pass the dovetail notch not in correspondenoe, so thatafull revolution of the key may be had without liability of the hooks being withdrawn from a holding with the faucetbody.
