page_text: LETTERS PATENT to John Edward Chambers, of Smethwick, in the county
of Stafford, Brewery Manager, for an invention of "IMPROVEMENTS IN TAPS
FOR DRAWING OFF BEER AND OTHER FLUIDS."
PROVISIONAL SPECIFICATION left by the said John Edward Chambers at
the Office of the Commissioners of Patents on the 27th February 1882.
JOHN EDWARD CHAMBERS of Smethwick in the County of Stafford Brewery
Manager. IMPROVEMENTS IN TAPS FOR DRAWING OFF BEER AND OTHER FLUIDS.
This Invention consists of a combined tap valve and socket-A socket with a
female screw is secured to the inside of the barrel and into this socket a valve
screws from the inside this valve is the fluid way and it is furnished on its inner
end with a flange cap and washer, the end projecting outwards in the socket has
grooves on the inside to receive corresponding projections on a collar cut on the
outside of the tap so that when the tap is screwed into the socket from the outside
the projections on the end of the tap engage in the grooves in the valve & keep
the parts together consequently turning the tap round turns also the screwed valve
until it is projected sufficiently into the barrel to expose the fluid way and allow
the fluid to be drawn off When the tap is withdrawn by unscrewing it from the
barrel the valve follows the tap and closes the aperture the fluid way being then
housed within the socket and the barrel or vessel is hermetically sealed.
Thus the valve is never free from the socket unless required to be so for the
purpose of cleaning; the tap and valve when locked as in use form one continuous
screw.

Referring to Sheet I Figure I. A is the tap with its screwed end B. and its key
and nipple, C,, D, is the brush with its flange, E,, F, is the valve with its
washer, G, seen separately in elevation in Fig 4, HH" are the projections in the
valve affording the fluid way, K is the guard by which the valve is prevented from
being driven into the barrel, The inner end of the tap as shewn in Figure 2 is
furnished with varied studs or nipples C' which studs engage in grooves C at the
end of the valve as shewn in Figure 3 and thus the tap and the valve are keyed
together and the valve is caused to follow the screwing or unscrewing of the tap by
the action of the multiple threaded screw on the periphery of both the threads of
this screw are shewn at I I' Figure 2. Figure 5. shews an inside end view of the
flange, E, on the bush or socket and the flange, (G,) on the valve by this flange the
bush or socket is screwed to the barrel from the inside the guard, K. preventing
the extension of the valve, F. beyond a certain distance into the barrel.

page_text: The action is as follows The tap A is inserted into the valve, F, which valve
when the tap is closed is housed within the bush or socket, D, the end of the tap
being keyed into the end of the socket by the studs C engaging in the grooves Ci
thus combining the two parts together It follows that screwing the tap into the
socket consequently screws the valve out of it and into the interior of the barrel
exposing the perforations H' H and providing a fluid way into the tap The
reverse action draws the valve back into the socket and closes the fluid way.
The Drawings shewn on. Sheet 2. represent a tap consisting of the same parts
but arranged so that the socket or bush may be inserted through the tap hole from
the outside instead of the inside of the barrel. The socket is formed tapered and
screwed coursely on the outside as seen detached at Figure. 8. and on the face it
has a hexagonal nut, a, by which by means of a spanner it can be screwed into
the tap hole the valve seen separately in Figure. 9. having first been screwed into
the socket when the end of the valve will appear in the socket as seen in Fig 10
The tap can then be keyed into the valve as shewn in Figures 6 and 7. and worked
precisely the saine as the form of tap shewn in Sheet 1.
Having thus described the nature of my said Invention and the manner in which
the same is to be performed
I claim the several Improvements in taps by the Employment-
Firstly of a quick acting or mutiple screw as and for the purpose herein described,
Secondly. The improved connection between the tap and valve by means of the
nipple and key action by which the tap and valve are locked together and follow
each other as herein described
Thirdly. I claim the application of a guard to prevent the valve leaving
the bush and Generally I claim the construction of a form of taps consisting
of the three parts the body or barrel of the Tap commonly called the tap the valve
or fluid way and the brush or socket arranged connected and working together
substantially in manner herein more fully set forth and specified.
In Witness Whereof I the said John Edward Chambers have hereunto set my
band and seal this twenty third day of August in the year of our Lord one
thousand Eight hundred and eighty two.
