Improvements in or in connection with Tapping Casks and other
Vessels.
I, HEZEKIAH DAVIS NORTHUP, of Fort Edward, in the County of Washington, and
State of New York, United States of America, Gentleman, 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 :-
My invention relates to improvements in combined cocks and couplings for
barrels and other vessels; and it consists of the device herein shown and described,
composed of two separable sections, one of which is permanently secured to the
barrel and the other being removably attached to the pipe, through which the liquid
is drawn from the barrel.
Referring to the accompanying drawings;
Figure 1 shows the two members of the coupling separated and in longitudinal section.
Figure 2 is a cross section on the line -, figure 1.
Figure 3 is a detail perspective view of the valve.
As represented in the drawings, A is the plug section of my device, which has on
its outer side a screw thread, by which said section is secured in the barrel.
The
said section is bored to receive the tubular valve stem b, of the spring actuated
valve B. The upper end of said section is provided with an internally screw threaded
chamber C, for receiving the screw plug D, of the coupling device. Attached to or
formed on the lower end of the plug section A, is a perforated chamber, E, for the
purpose of containing the spring F, by which the valve B is forced against its seat
so as to form a tight joint at that point when occasion requires. The tubular valve
stem of the valve B should extend upward far enough to nearly reach the bottom
of the chamber C, whon said valve is seated, as shown in figure 1, and said stem
must be perforated near the valve B, as shown at f, to permit the liquid in the barrel
to flow through the device when the valve B is open.
The screw plug D, is bored to receive the pipe G, which is uniform in diameter
with and adapted to register with the upper end of the tubular stem b, so as to form
a tight continuous pipe with said stem. The pipe G, has a circumferential groove g,
cut around its outer side, and the point of a set screw d, which is inserted through
the side of the screw plug D, engages in said groove, so as to permit said plug to
be turned on said pipe and to allow of the removal of said plug from said pipe. By
this means one screw plug D, can be used interchangeably for any number of the
pipes G, in my device.
The plug section A, is permanently secured in a barrel or other similar vessel for
containing liquids, of which ale and lager beer are the kinds for which my device
is specially designed, and the valve B, is kept normally closed to its seat by the
pressure of the spring F, so as to prevent any flow of the liquid from the barrel,
and in this condition the barrel and its contents can be safely transported from
place to place without danger of leakage. To draw from the contents of the
barrel the pipe G, (which must be permanently attached to the pipe through which
the liquid is conveyed to the place of delivery) is inserted in the bore of the plug
section A, wherein it will not at first bear against the end of the tubular stem b,
thereby permitting the screw plug D to be partially screwed into the plug section A,
before the end of the pipe G, presses against the tubular stem b, to open the valve B,
and by so doing a perfect connection can be formed between the end of the pipe G,
and stem b, before the liquid begins to flow from the barrel, and leakage therefrom
is thereby prevented. The screwing in of the screw plug D, is then continued until
the valve B, is fully open whereupon the liquid from the barrel after passing through
the perforations of the tubular stem b, will pass through said stem and pipe G and so
on to the point of delivery.

page_text: The spring F, abuts directly against the large outwardly tapering end of the
valve B, and in order to form direct passages from the space within the spring to
the inlet apertures of the valve stem, the large face or end of the valve is provided
with one or more deep transverse grooves or channels g¹ (two grooves are shown
in the present instance crossing each other at right angles) thereby forming lateral
passages g, from the space within the spring towards the edge of the valve and
longitudinal passages h, (figure 2) from the ends of the transverse channels directly
to the inlets. These longitudinal passages are formed by reason of the tapered
form of the valve and the depth of the grooves. By this means the device is
prevented from clogging by sediment and floating particles and the liquid has free
flow to the valve.
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 :
1st. The combination, with a plug section that is permanently secured in a barrel
and which is provided with a spring seated grooved valve, having the perforated
tubular stem of the screw plug to screw into the plug section and provided with a
set screw and pipe section, passing completely through said screw plug to enter the
bore of the plug section and co-act with the valve stem to open the valve and form
a continuous discharge through the valve stem and pipe from the barrel, said pipe
having an annular groove, into which the set screw extends and by which the pipe
is detachably held, extending through the screw plug, substantially as described.
2nd. In a combined cock and coupling for barrels etc., a valve consisting of a
tubular stem open at the outer end and provided with radial inlets at the inner end,
and the beveled valve proper on the inner end of the stem provided with one or
more transverse grooves or channels extending across its end wall or face as and for
the purpose set forth.
3rd. A cock for barrels etc., comprising a plug section adapted to be secured in
a barrel and having a longitudinal bore, a perforated chamber at the inner end of
the plug, a valve adapted to close the inner end of the bore and consisting of a hollow
stem extending into said bore and provided with one or more inlets near its inner
end, and the beveled valve proper on the inner end of the stem located in said
chamber, and provided with one or more transverse grooves or channels extending
across. the flat end or face of said valve proper and a coiled spring longitudinally
located in said chamber and at one end hearing against said grooved face, sub-
stantially as described.
4th. A combined cock and coupling comprising a plug section to be permanently
secured in a barrel; and provided with a longitudinal bore, a spring seated valve
having a tubular stem located in said bore, the detachable screw plug provided with
a longitudinal bore e, and the connecting pipe section uniform in diameter with said.
valve and extending completely through the bore of the screw plug and removably
secured therein, for the purpose set forth.
