TAPPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 602,510, dated April 19, 1898.

Application filed March 1l, 1897. Serial No. 626,912. (No model.)

T0 @ZZ whom t may concern.-

Be it known that I, JUDsoN N. KNAPP, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Tapping Apparatus,

of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in tapping apparatus, and has for its object the production of a device which is particularly practical and simple in construction, is highly effective in use, and permits the passage of fluids therethrough in opposite directions; and to this end it consists, essentially, in the general combination, construction, and arrangement of the component parts of a tapping apparatus, all as hereinafter fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a longitudinal section, partly in elevation, of my improved tapping apparatus shown as operatively secured to a portion of a barrel or other receptacle, parts of said ap,- paratus being broken away. Fig. 2 and 3 are respectively vertical and horizontal sections taken on lines 2 2 and 3 8, Fig. l. and G are respectively isometric views of the tap or bushing, the key or valve-piece, and the plug foroperatin g said keyor valve-piece. Fig. 7 is an isometric view of a detached portion of the tap or bushing. Fig. Sis a transverse section taken on line S S, Fig. 4. Fig. 9 is an isometric view of the nut arranged in the inner end of the tap or bushing and movable lengthwise of the key or valve-piece. Fig. lO is an elevation of a spring for engaging said nut, and Fig. ll is an isometric view of a wrench for operating the key or valve-piece.

My improved tapping apparatus is secured to a suitable barrel or other receptacle and preferably consists of a tap or bushing A, a key or valve-piece B, a plug C, and a pipe or conduit D. The tap or bushing A is usually inserted into an aperture e, formed in the end wall c' of the barrel or other receptacle provided with my invention; but it is obvious that, if desired, said tap or bushing maybe se- Figs. 4., 5,'

cured to a side wall of said barrel or other receptacle. The inner end of the aperture e and the adjacent portion of the periphery of the tap or bushing A are usually threaded, and the outer ends of said aperture and tap or bushing are formed with separat-ed shoulders e2 a, which engage an interposed packing-ring a. The threaded surfaces of the aperture e and tap or bushing A facilitate the securement and removal of the tap or bushing, and the packing-rin g a obviates the escape of any liquid between said threaded surfaces. It is obvious,however, that the tap or bushing may be otherwise secured to the barrel or receptacle provided with my improved tapping apparatus. K

The tap or bushingA is preferably formed with a substantially circular engaging face a2 and inlet and outlet fluid-passages, which usually consist of a substantially central lengthwise chamber a3, inlet and outlet openings 664 a5 a5, and an inlet conduit or groove a6. The chamber a3 is preferably formed with a closed inner end and a tapering central portion decreased in diameter toward said closed inner end. The inlet-openin g a4 is usually arranged above the outlet-openings a5, as best seen at Fig. l, and said inlet and outlet openings usually extend outwardly from the chamber a3 to the exterior face or periphery of the portion of the tap or bushing, which projects beyond the inner face of the wall e. The inlet conduit or groove a6 opens from the outer or upper end of the chamber a3 and extends substantially lengthwise of said chamber between the inlet-opening a4 and the circular engaging face a2. The lower end of the chamber a3 of the tap or bushingAis usually provided with lengthwise shoulders a7 and an annular shoulder as. The construction of these shoulders may be facilitated by forming the lower end of the tap or bushing A of a separate piece of :metal or other suitable material, having its upper end secured to the lower end of the remaining or upper portion of said tap or bushing. lt is apparent, however, that the tap or bushing may, if desired, consist of a single piece of metal or other suitable material.

As clearly seen in Figs. l and 2, the key or valve-piece B is arranged within the chamber 0.3 of the tap or bushingA and is usually IOO formed with a substantially circular engaging face b and inlet and outlet Huid-passages, which usually consist of a central lengthwise chamber b', an inlet conduit or groove b2, and outlet-openings b3. Said key or valve-piece is rocked on a longitudinal axis by the plug C or a suitable wrench C, Fig. 1l, for moving the inlet conduit or groove b2 and the outletopenings bsinto and out of alinement with the inlet and outlet openings co4 a5 a5 of the tap or bushing A. The central portion of the key or valvepiece decreases in diameter toward the inner or lower end of said key or valve-piece and usually closely fits the central portion of the tap or bushing A. The upper end of the key or val ve-piece is preferably enlarged and formed with an upwardly-inclining annular shoulder b4, arranged slightly above an annular shoulder ci at the upper end of the tapered or central portion of the chamber CL3. The lower end of the key or valve-piece B is usually threaded for engaging a nut b5, which is movable lengthwise of said lower end, and is prevented from revoluble movement by the shoulders a7 of the tap or bushing A. A suitable spiral spring b encircles the inner or lower end of the key or valve-piece B and is engaged with the nut b5 and the annular shoulder as of the lower end of the chamber CL3. The threads upon the inner end of the key or valve-piece for engaging the nut b5 are preferably so inclined that as said key or valve-piece operates to move the conduit or groove b2 and the outlet-openings b3ta out of alinement with the inlet and outlet openings a4 a5 d5 the nut h5 is drawn upwardly for additionally tensioning the spring h6 and compelling the same to hold the key or valvepiece downwardly with additional force. The nut b5 and the spring h6 form a particularly practical and effective means for firmly holding the key or valve-piece B in position; but is obvious that any other suitable means may be used, if desired.

The plug C is secured within the upper end of the chamber a3 of the tap or bushing A and is formed with inlet and outlet conduitsr c c for communicating with the inlet and outlet duid-passages of the tap or bushing A and the key or valve-piece B. The outer end of the inlet-conduit cis usually arranged Vat an angle with the conduit c' for forming av convenient and effective handle or lever which facilitates the securement of said plug in operative position within thetap or bushing. The inner end of the conduit c usually consists of a chamber c2, surrounding the ad-y jacent portion of the outlet-conduit c', and an opening c3, which extends from said chamber to the exterior ofthe plug C for communicating with the inlet conduit or groove a6. The inlet-conduit c is usually provided with an enlarged portion c4, and a tubular valve c5, which is arranged within said enlarged portion, is formed with a iiexible wall and communicates with the outer or upper end of said cond uit c. The iieXible wall of the valve c5 is formed with a lengthwise groove or slit c, and a spiral spring c7 is usually arranged within said valve for preventing undue bending of its flexible wall. The pressure within the valve c5 opens the slit or slot ci', and the pressure within the enlarged portion c4 of the conduit c closes said slit or slot. The valve c5 is particularly simple and effective but it is obvious that any other suitable valve may be used, if desired.

The plug C is provided with annular engaging faces o8 o9 and suitable shoulders or lugs 010 ou. The faces e8 a9 are arranged above the corresponding faces d2 l) of the tap or bushing A and the key or valve-piece B, and suitable yielding washers or packing-rings f are normally interposed between said faces cS o9 a2 h for preventing communication between the inlet and outlet fluid-passages of said tap or bushing and key or valve-piece. The shoulders or lugs C10 project from opposite portions of the periphery of the plug C and are preferably formed with inclined upper faces, which engage the upper faces or shoulders of opposite partially circular grooves d10 in the inner face of the tap or bushing A. Opposite lengthwise grooves a extend from corresponding extremities of the grooves d10 to the outer end of the tap or bushing A and permit the entrance of the shoulders or lugs C10 to the grooves d10. The shoulder or lug c preferably consists of a half-round projection which extends from the lower end face of the plug C into the upper end of the chamber b' of the key or valvepiece B and engages a perforated shoulder hl, provided in the upper end of said chamber. The shoulders or lugs n10 hold the plug C in its operative position, and the shoulder or lug c11 forms a particularly simple means for engaging and partially rotating the key or valve-piece B.

The pipe or conduit D communicates with theoutlet-openings a5 a5 of the tap or bushing A and extends ,downwardly to the bottom wall (not illustrated) of the barrel or other receptacle provided with my invention. As preferably constructed, the pipe or conduit D consists of sections d d', telescoping one within the other, the bottom end of the lower section being formed with suitable openings. The top end of the upper section CZ is usually enlarged for encircling the lower or inner end of the tap or bushing A and is suitably secured to said tap or bushing. The section d is generally formed with a transversely-extending chamber CZZ, which is provided with an opening d3 in one end and upper and lower openings d4 d5, communicating with the upper and lower portions of the pipe or conduit D. A valve-piece CZ is arranged in the chamber cl2 and is formed with openings (Z7, which are alined with the openings d3 d4 d5 for permitting the passage of the outgoing fluid from either the lower portion of the pipe or con# duit D or the chamber d2 to the upper portion of said pipe or conduit. The valve-piece d6 IOO IIO

is'actuated by a suitable operating-piece d8, having one end engaged with said valve-piece and its opposite end passed through an aperture e3 in the adjacent side or wall e4 of the barrel or other receptacle provided with my invention. A suitable packing-ring e5 and collar c6 encircle the outer end of the operating-piece for preventing leakage of the fluid from the barrel or other receptacle around the operating-piece d8. A socket-wrench e7 (shown by dotted lines in Fig. l) may be used for turning the operating-piece d8 and actuating the valve-piece d6.

Hy improved tapping apparatus is usually used in connection with barrels or receptacles from which the liquor is forced by the pressure of an incoming fluid, as air, and consequently said apparatus is so constructed as to permit both the entrance of the' air and the outflow of the liquor.

In the operation of my improved tapping apparatus the incoming air or other fluid passes from the inlet-conduit c into the upper end of the chamber a3 beneath the upper packing-ring f and iiows through the conduit or groove aGinto the space interposed between the shoulders a9 h4, whence it passes through the conduit or groove h2 and the inlet-openin g a4 to the interior of the barrel or other receptacle. The outgoing fluid or liquor passes from either the chamber d2 or the lower end of the pipe or conduit D, through the tubular valve-piece d, to the upper end of the pipe or conduit D, and thence escapes through the openings a5 a5 h3 to the chamber b of the key or valve-piece B, whence it passes to the outlet-conduit c' of the plug C. After the desired quantity of liquor has been withdrawn from the barrel or other receptacle to which my improved tapping apparatus is secured the plug C is partially rotated until its shoulders or lugs c10 are alined with the lengthwise grooves a of the tap or bushing A, whereupon said plug may be readily withdrawn. No escape of the liquor takes place upon the withdrawal of the plug C, as the partial rotation of said plug moves the conduit or groove b2 and the outlet-opening b3 out of alinement with the inlet and outlet openings a4 a5 a5 of the tap or bushing A.

The operation and construction ot' my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings.
