To all whom it may concern.-

Be it known that LBENJAMI C. ANDERSON, acitizen of the United States, residing in the borough of Brooklyn, in the city and State of New York, have invented a certain new and useful Improvement in Bushing-Valves and Faucet-Couplings, of which the following is a- It has long been common to provide ametallic bushing for barrels carrying a valve in its interior which is operable from the outside, with provisions for attaching a coupling and for opening the valve by the same mo tion thereof which attaches it to the bushing. The presentinvention involves that construction and mode of operation. I have devised important improvements, one of which is to make the bushing with the exterior portion of brass and the inner portion of soft metal.

It has long been practiced in certain arts to cast in a mold a single article of two different metals, introducing one before the other under proper conditions to effect a permanent junction. I have discovered that such mode of manufacture applied under proper conditions and with proper metalswillproduce a faucet-bushing having a hard exterior to allow rough usage of the barrel and presenting to the interior contents of the barrel only a soft-metal portion which is economical in material and labor and shall not be affected by any acid.

I have also made important improvements in the form and construction of the parts in other respects, as will be set forth below and pointed out in the claim.

The following is a description of'what'I consider the best means of carrying out the invention.

The accompanying drawings form a partof this specification.

Figure 1 is a central longitudinal section of the hard-metal portion of my bushing. This figure also shows in elevation the plug in the relation which it assumes after the bushing has been added to and finished. The plug is in the closed position. Fig. 2 isacorresponding section through the completed bushing and all the associated parts. The plug is in the open position. Fig. 3 is an end view as seen from the right in the closed position. Fig. 4 shows the same in the open condition,

and Fig. 5 is a side view of the coupling and key.

Similar letters of reference indicate corresponding parts in all the figures where they appear.

' A is aportion of the barrel, usually the mid-length of a stave, inwhich the bushing is inserted and is permanently retained.

B is the exterior portion of the bushing, formed with an internal extension B. C is a further extension of soft metal permanently united, so as to serve as a unit, with the brass portion B B of the bushing. In the extension 0 are liberal apertures c on opposite sides, which when the plug is properly turned admit the liquid to be discharged. The midlength and inner portion of the bushing is bored conically, as shown, the smaller end outward toward the exterior of the barrel.

D is the plug, having its corresponding portion tapered, as shown, so as to make a tight and easy fit and having apertures d, corresponding to the apertures c in the bushing. These communicate with the passage d in the center, which extends to the small end of theplug. The large end of the plug is closed and is recessed and receives the inner end of ahelical spring E. Acorresponding disk G, recessed in its inner face, receives the other end of the same spring. This disk is held adj ustably by screw-threads G in the bushing and may be set in or out by the aid of a forked key (not shown) engaging in the holes g.

The compound bushing B B C has longitudinal grooves 19 in its interior, from the bottom of each of which extends a partially-circumferential groove 1 There are two of the spline grooves 17 on opposite sides of the axis and two of the connected grooves b. The latter are slightly inclined, so as to draw inward the coupling when it is inserted and partially revolved, as will appear farther on. The outer end (the smaller end) of the plug is peculiarly formed. It serves to engage with the coupling-piece'and key by the aid of deep open slots 61*. (See Figs. 1 and 2.)

- H is the coupling and key. It is provided with a flange H, fitting tightly against the outer face of the bushing. H H are stout projections on opposite sides, which when the coupling is engaged with the bushing are ICO received in the slots d of the plug and extend outward through such slots into the bushing. As the coupling is introduced these projections H are received first in the splinegrooves 11 of the bushing, and as the coupling is thrust farther inward it enters the outer end of the plug, the coupling matching within the plug and the projections H moving along the straight open slots (Z When it has been thrust in to the full extent required, the flange H matches tightly against the outer face of the bushing. Then the turning motion is commenced, and these projections H remaining engaged in the slots d and thereby turning the plug D, also extend out into the bushing and are by the turning motion carried into the slightly-inclined partially-circumferential grooves 17, and thereby lock the coupling.

In the construction of the bushing the soft metal is brought into permanent union with the brass by placing the previously-cast portion B in a mold and, having warmed the whole, pouring soft metal to fill the remainder of the mold and form the required unitary structure. smoothly and easily bored and in assembling the plugis introduced, followed by the spring, and on applying the disk G and screwing it up to a gentle contact with the spring the device is ready to serve for an indefinite period.

The liability of brass faucets to form verdigris is an objection to the use of brass as the material for faucets for manyliquids, among which are the whole line of fermented and brewed beverages. However carefully the metal is tinned, expense is involved in such defence, and the brass is always liable to be imperfectly tinned or to be exposed to corrosion by the removal of the whole or a part of the coating. It is a common belief among those in the trade that vinegar, which is often intentionally or unintentionally produced in the contents of the barrels, will in time remove the ordinary thin coating. My faucet having the entire main body and inner end of white metal insures against any possible exposure of brass to the contents of the barrel.

My construction insures that the plug shall be in the closed positionbefore the coupling can be withdrawn, and the same conditions insure that all the parts shall be in position to again receive the same or a similar coupling when required. The turning of the coupling in one direction engages the coupling strongly and tightly with the barrel and also turns the plug in the required direction to allow the flow of the liquid. It may serve The soft-metal portion 0 isperfection and is simpler and less liable to derangement than any previously known to me. It requires no packing.

K is a perforated shell formed separately and applied as a strainer over the inner and mid-length portions of the bushing. It is engaged with the bushing by screw-threads at K. When used with ale or other liquid containing solid or semisolid matter, this shell presents a large finely-perforated surface, through which the liquid is certain to find sufficient entrance even if .many of the apertures are stopped.

I can avoid much of the labor of boring the soft metal by using an iron or other hardmetal core, finely finished, of the proper tapering form.

Some of the advantages due to certain features of the invention may be separately enumerated as follows: By reason of the fact that the bushing is composed of two metals formed in a single rigid part by casting the soft metal 0 upon the brass B B,I am able to have the outer part of a material which maintains its smooth condition when the barrel is rolled over nails, stones, or other hard irregular surfaces to allow it to be kept in condition for an indefinite period to receive the flange H of the coupling H and make a tight joint therewith, while the structure is produced in high perfection at less cost than if it were all brass and, above all, can present to the interior of the barrel under no conditions any but the harmless surface of the soft metal which constitutes the main body and inner end of the bushing.

I claim as my invention- The bung-bushing B B C, composed of two metals, the outer part B B of brass and the inner and main part 0 of soft metal cast together and adapted to serve substantially as herein specified.

In testimony that I claim the invention above set forth I affix my signature in presence of two witnesses.
