PROVISIONAL SPECIFICATION.
Improvements in Taps and Bushes for Casks.
1, CHARLES HARGRAVE, of Bondgate Grange, Ripon, in the County of York,
Gentleman, do hereby declare the nature of this invention to be as follows:-
According to this invention the bush carries on the inside of the cask a plug tap
which is turned in the act of putting on or taking off the outer tap or tap proper.
The outer tap is secured in place by giving it a quarter turn which causes inclines
upon it to interlock with inclines on the bush. The end of the outer tap is provided
with a key which fits into the end of the plug of the tap carried by the bush in
such manner that as the outer cock is secured in place by giving it a quarter turn
the inner tap is opened and when it is taken off the inner tap is closed.
I use a small disc of cardboard or metal or other suitable material to enable the
casks when full to be sealed up so as to prevent the contents being tampered with
without breaking the seal.

COMPLETE SPECIFICATION.
Improvements in Taps and Bushes for Casks.
1, CHARLES HARGRAVE, of Bondgate Grange, Ripon, in the County of York,
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 :-
According to this invention the bush carries on the inside of the cask a plug tap
which is turned in the act of putting on or taking off the outer tap or tap proper.
The outer tap is secured in place by giving it a quarter turn which causes inclines
upon it to interlock with inclines on the bush. The end of the outer tap is provided
with a key which fits into the end of the plug of the tap carried by the bush in
such manner that as the outer cock is secured in place by giving it a quarter turn
the inner tap is opened and when it is taken off the inner tap is closed.
I use a small disc of cardboard or metal or other suitable material to enable the
casks when full to be sealed up so as to prevent the contents being tampered with
without breaking the seal.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section of the bush,
Figure 2 is a front elevation of the same,
Figure 3 is a longitudinal section of the tap and
Figure 4 is a rear elevation of the same,
Figure 5 shows a modified form of bush and
Figures 6, 7 and 8 show the adaptation of the arrangement to a self
venting tap.
In these figures similar parts are denoted by the same letters.
a is the shell of the bush and b is a hollow plug within it. c is the head of the
cask. a' a' are openings in the shell and are openings leading from the
exterior to the interior of the hollow plug. d is a spring tending to force the plug
home. aa are radial slots in the outer face of the bush and are radial slots
in the end of the plug. When the plug tap in the bush is closed as shown in the
[Price 6d.]

page_text: drawings these slots are in a line as indicated in Figures 2 and 7. In order to
prevent the plug from being turned ! employ the disc of metal or cardboard shown
in Figures 9 and 10 bent up from a blank of the form shown in Figure 11. This
disc is placed in the hole in the bush against the end of the plug with its ridge
lying in the slats a² 62 and is secured by a seal.
As shown in Figures 1 and the outer face of the bush a extends beyond the
head of the cask and as shewn in Figures 2 and 7 is provided with two
projections a³ a³. The inner face of the tap e is provided with two corresponding
overhanging lips ele which when the tap is in place lie beneath the projecting
portions of the bush. eis a key upon the rear of the tap which fits the slots b² 13
in the end of the plug b. It will be obvious that in place of the arrangement
shewn in the drawings the overhanging lips el el might be upon the bush and the
projections a³ a³ upon the tap. A washer may be provided to ensure a tight joint
between the tap and the bush.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I do not claim generally a plug in the interior of a bush turned in the act of
putting on or taking off the tap but what I do claim is :-
1. The combination of a tap, a bush, a plug inside the bush (which is turned in
the act of putting ou or taking off the tap) and projections upon the bush or tap
and overhanging lips upon the tap or bush which interlock with each other
substantially as described.
2. Taps and bushes substantially as described and shewn in the drawings.
