Improvements in and relating to Devices for Use in Tapping
Beer Barrels and the like.
I, JOHN MOHN of 360 Monroe Avenue, in the City of Detroit, State of
Michigan, United States of America, Merchant, do hereby declare the nature of
this invention, and in what manner the same is to be performed, to be particularly
described and ascertained, in and by the following statement :-
The invention consists in the construction of a combined tap-bushing and
coupling and a stuffing box having a complementary coupling or its foot adapted to
be engaged and disengaged with the coupling on the tap-bushing all arranged and
combined as and for the purpose hereinafter set forth.
In the drawings, Fig. 1 is a vertical central longitudinal central section through
my improved device as in use.
Fig. 2 is a perspective view of the tap bushing.
Fig. 3 is a perspective view of the foot of the stuffing box showing the coupling.
My device is intended to be used especially in tapping beer barrels, and barrels
containing similar fluids fed under pressure, and it is intended to form a permanent
metallic bushing for the tap, to which the stuffing box is coupled through both of
which the tap tube is adapted to be inserted.
Thus the head of the barrel is never injured, as by driving the tap into the wood, as
it is usually done, and a tight joint is always insured with a simple and economical
construction.
A is the head of a barrel or keg. B is a bushing screwed into the tap hole
therein, and having a central cylindrical aperture C, adapted to be closed by a
cork D which may be forced into the barrel by the tap tube E.
The bushing below its top has the annular cup shaped flange F, entering a
counterbore G in the barrel head, and within which is the coupling socket or
groove H.
On the outer face of the extension I of the bushing and within the groove H,
are the oppositely inclined segmental coupling flanges J, at the ends of which are
the entering slots K.
Lis a tubular stuffing box having the internal flange M on which rests the
packing rings M' clamped by the annular packing nut N engaging a screw threaded
bearing in the top of the stuffing box.
At the bottom of the stuffing box is the bell shaped coupling foot O, having on
its inner face the coupling lugs P adapted to engage in the slots K and by a partial
turn to couple the stuffing box to the bushing and form a tight joint by clamping
the packing ring Q between the top of the bushing and the shoulder R on the
coupling foot. The edge of the coupling foot enters the groove H, so that the
coupling head on the bushing is below the outer face on the barrel head, thus when
the barrel is filled, it does not project, and hence does not interfere with pasting the
Government stamp over the tap hole, nor present any protuberance which may be
broken.
To use the device the operator couples the stuffing box to the tap-bushing_enters
the tap tube E in the aperture through the stuffing box, forcing the cork D into
the barrel, S is a nipple for securing a pipe or hose for admitting air under pressure
into the barrel to force the liquid out through the tap tube.
The bushing has a face flange T adapted to rest on the outer face of the barrel
head, and having suitable notches T' for a wrench hold to screw it in and out.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In a bung bushing and tap, the combination with a bushing member having a
threaded centrally perforated shank, a recessed outer face, and a central projection I,
in the recess having oppositely inclined coupling flanges J, on its sides, spaced
apart, a centrally apertured stuffing box having a bell shaped coupling foot O,
formed with inwardly extending lugs P, adapted to engage the flanges J, the
packing R, between the bushing and box, the flange M, in the upper end of the
box, the packing M', on the same, the nut N, in the upper end of the box, and
the nipple S, substantially as described.
