Complete Specification Left, 12th Nov., 1891-Accepted, 23rd Jan., 1892
PROVISIONAL SPECIFICATION.
Improvements in Taps.
I, FREDERICK CHARLES FULLER, of Lurke Street, Bedford, in the County
of Bedford, Brewer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to that class of tap which at the inlet end is formed with a
series of perforations and which chiefly intended for application to beer and other
barrels.
The chief object of my invention is to provide means whereby such taps may be
more readily cleaned than heretofore and to this end it consists in making one part
of the tap removable, for instance the perforated portion, or in providing a hole
normally closed by a plug. When the perforated portion is made removable it
is preferably adapted to be connected to the other portion by means of screw
threads.
It will be obvious that by removing the perforated portion or the plug a brush
may be passed entirely through the tap to thoroughly cleanse the same.

COMPLETE SPECIFICATION.
Improvements in Taps.
I, FREDERICK CHARLES FULLER, of Lurke Street, Bedford, in the County
of Bedford, Brewer, 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 that class of tap which at the inlet is formed with a
series of perforations and which is chiefly intended for application to beer and other
barrels.
The chief object of my invention is to provide means whereby such taps may
be more readily cleaned than heretofore, and to this end it consists in making one
part of the tap removable, for instance, the perforated portion, or in providing a
hole normally closed by a plug. When the perforated portion is made removable
it is preferably adapted to be connected to the other portion by means of screw-
threads.
It will be obvious that by removing the perforated portion or the plug a brush
may be passed entirely through the tap to thoroughly cleanse the same.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which :—
Figure 1 is a longitudinal section of a cock or tap, the perforated portion of
which is made removable; and,
Figure 2 is an elevation of such removable perforated portion detached:
Figure 3 is a section on the line xx, Figure 1 :
Figure 4 is a sectional view shewing the arrangement of a removable plug.
a indicates the shank of the tap, and the perforated portion thereof, which
portion, as shewn in Figure 2, is provided with screw-threads and is adapted to
engage with corresponding threads in the shank, as shewn in Figure 1. It is obvious
that, when this perforated portion is removed, it can be readily cleansed and also
that a brush can be passed right through the cock.

page_text: In practice I advantageously make the plug solid except for the hole there-
through, and this hole I preferably make of such size and shape as to correspond
with the passage through the cock in order to avoid the formation of any projecting
edges or ledges which might retain dirt or impurities.
In the modification of my invention shewn in Figure 4 the extreme end of the
shank of the cock is provided with an internal screw-threaded hole which is
normally closed by a plug d, which plug forms the end of the shank.
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. A cock or tap the rear or perforated portion of the shank of which is made
detachable, substantially as, and for the purpose, described.
2. The manufacture and use of the improved cock or tap hereinbefore described
and illustrated in the accompanying drawing.
