TAP OER BUSHING FOR B ARRELS.

SPECIFICATION forming part of Letters Patent No. 539,162, dated May 14, 1895. Application fi ed May 16,1893. Serial No. 474,445. (No model.)

To all whom it may concern.-

Be it known that I, HENRY 0. BLACK, a citi zen of the United States, residing at San Fran cisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Taps or Bushings for Barrels; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the .art to which it most nearly appertains to make, use, and practice the same.

The present invention has relation to certain new and useful improvements in taps or bushings for barrels and consists in the arrangement of parts and details of construction as will be hereinafter more fully set forth and described. I

My invention consists in making the two semi circular inclined grooves of equal depths, and causing a limited rotation of the faucet therein, by bringing the collar thereof in direct contact with the face of the bushing; and further in providing an operating key, having lugs of a uniform thickness, one being Wider than the other, which fit within the narrow and wide intersecting openings of the bushing, the lugs of the key projecting from a movable collar secured thereon, within which collar the key rotates.

Referring to the drawings forming apart of this application, wherein similar letters and figures of reference are used to indicate corresponding parts, Figure 1 is a view showing my 'improved bushing in section and applied to a bung of a barrel with a faucet connected therewith. Fig. 2 is a detail view of the fancet, partly broken away, showing the collar and lugs secured thereon and the saucershaped tin or metal washer and packing-ring in place; Fig. 3, a top plan view of the bushin g Fig. 4, a cross-sectional view of the bushing, showing more fully one of thesemicircular grooves cut therein; Fig. 5, a detail view of the operating-key for locking and unlocking the valve secured to the inner end of the bushing; and Fig. 6 is a detail sectional view of the saucer-shaped washer and the-packingring which fits therein.

The letter A, is used to indicate the bushing, which is screwed into thimble B, removably fastened within the barrel, and said thim ble may or may not extend entirely through the wood thereof. Within the thimble A, works the prismatic stem C, of valve C, which is rotated so as to be opened or closed by means of faucet tip D, which is of usual construction.

The outer end of bushing A, is provided with the annular flange A, which bears upon the top of the thimble when the bushing is secured therein, and likewise said flange is countersunk, see a, in order to protect the bushing from damage, as fully described in Letters Patent No. 449,513.

Within the bushing is located the annular shoulder E, which forms a seat for the packing ring, and the metal located between the seat or shoulder E, and flange A, is cutaway in order to provide an annular groove, which groove being intersected by two openings, 1),

b, one wider than the other, out through the annular flange, forms. two semi circular grooves F, F. The under face of the annular flange A, intermediate of the narrow and wide openings, I incline in opposite directions, which convert the grooves into oppositely inclined semi-circular ones, but of relatively equal depth.

From the faucet Gr, project the lugs c, 0, one wider than the other, which correspond 'with the openings b, b. These lugs are of such thickness as to work freely within the semi-circular grooves, F, F, passing therein through openings 1), b. Said lugs have their upper faces inclined in opposite directions,

which correspond with the incline or pitch of from the top of the flange A and lower end of the inclined under face thereof, that is from 2 to 3. Consequently as the faucet is turned to open the valve the incline lugs work IOO against the incline face of the flange A, which constitutes the top of the semi-circular grooves, and gradually draws the faucet inward until the face of the collar impinges tightly against the upper face of flange A, when the valve will be opened.

In view of the fact that the depth of metal from 2 to 3 is greater than the distance from under face of collar II, and point 1 of the incline lugs, it is obvious that the faucet is prevented from being turned such a distance as will take the lugs from within the semi-circular grooves, and at the same timewill prevent the faucet, for the same reason, when inserted, from being rotated in the wrong direction, hence compelling the valve to be locked when the faucet is withdrawn, owing to the fact that when the faucet is inserted it can only be rotated in the direction to open the valve and in order to close the valve it must be retated in the opposite direction, and it can be rotated only such a distance, by reason of the difference in measurement from under surface of collar and point 1, of the lugs and of the flange from 2 to 3, as will suffice to bring the lugs into line with its entrance openings 1), b.

Upon the lower reduced end or tip portion of the faucet below the lugs c, o, loosely fits the saucer shaped metal collar H, which as the faucet is moved inward compresses the packing ring H also secured upon the reduced portion of the faucet which fits therein. This packing ring rests against annular seat within the bushing. Owing to the peculiar shape of the collar, H, being that of a saucer, the packing ring ['1 when compressed, by the inward movement of the faucet, will not expand beyond the outer edge thereof, consequently permitting a much tighter joint to be made between the faucet and bushing seat, in order to prevent escape of liquid while the valve is being opened. Without the use of this collar, the flange K, of the faucet will contact directly with the packing ring and cause same to drag on its seat as the faucet is rotated inward. By interposing the metallic collar between the packing ring and this flange, the faucet will bear and rotate on the same, hence preventing the packing ring from dragging and becoming unseated and obviating the undue expansion of the same on the Essie.

side of t the wide groove, when a narrow and wide one is cut within the bushing.

The operating key for opening and closing the valve is indicated by the letter K. This key has a tip which corresponds with the valve spindle and fits thereover. Upon the key is movably secured the ring L, which is provided with two lugs Z, Z, which correspond with openings b, b and fit therein. This ring bears against the collar K which fits upon the annular seat of the bushing when the key is inserted therein, and is held in place by means of the retaining collar L, secured to the key by pin Z Within the ring L, is cut the opening m, within which works pin or stud m, projecting from the key, as shown in Fig. 5. In order to open the valve for cleaning the barrel, the, the key is inserted within the bushing, the tip fitting over the valve spindle. When thus placed the lugs of ring L, will [it in the narrow and wide openings 1), b, of the bushing flange. The key is then turned within the ring L, until the pin or stud m contacts with end wall of opening m, which stops further rotation thereof. The valve is closed by reversing the rotation of the key. It will thus be seen that the ring L, in reality acts as a bearing for the key and a stop to limit the rotation of the same. v

Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent, is

The combination with a tap or bushing for barrels having a valve connected thereto, and provided in its upper portion with inclined semi-circular grooves and narrow and wide openings intersecting said grooves, of the operating key for opening and closing the valve, of the open ringloosely secured upon the key, of the wide and narrow lugs projecting therefrom, said lugs fitting within the wide and narrow openings of the bushing, and of the stop for preventing the rotation of the key within the ring when the valve has been opened or closed.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY C. BLACK.
