We EDWIN JOHN JONES, of 9 High Street, Wolverhampton in the county of
Stafford, merchant, and THOMAS JOHNSON, of Dudley Street, Bilston in the said
County, brass founder, do hereby declare the nature of this invention to be as
follows:-
This invention consists in the application to the description of taps and valves
named in the title, and which are fixed direct to vessels containing liquid to be
drawn off, of simple and efficient strainers for preventing any particles of solid matter,
except those which are very minute, from passing through such taps and valves,
such strainers being so constructed and fixed that they may be readily removed to
be cleansed, and afterwards replaced.
A tap or valve fitted with a strainer according to this invention, has the usual
tubular part which enters within the liquid. Such part is perforated as usual, but
preferably with considerably larger holes, and one part of the circumference,
preferably the top, is left unperforated. The back end of this tubular part is
closed by means of a screw-plug readily removable at pleasure, and the bore of the
tubular part is made parallel from the back end to a short distance in advance of
the perforations. A stad or pin is cast or fixed within the bore of the tubular part
just at the end of the parallel part, aforesaid, and a cylinder of wire gauze, forming
the strainer, is inserted within the parallel part, and maintained in place by means
of the stud or pin and the screwed plug, so that all liquids passing through the tap
or valve must first pass through the gauze. The gauze cylinder is open-jointed,
and is formed of a larger diameter than the bore of the parallel part aforesaid, so
that is has to be sprung into its place, and consequently tightens itself firmly
against the interior of. the perforated part in which it is placed. The strainer is
placed with its open joint along the unperforated part, aforesaid, of the tubular end
of the tap or valve. It can be readily removed for being cleansed, by first
removing the screwed plug at the end of the tubular part aforesaid.
By the use of a strainer as above described we are enabled to form the
perforations in the tubular end of the tap or valve, larger. than usual, and thus
Jessen their liability to being choked up by seeds, particles of hop, or other solid
substances.

Improvements in or relating to Taps and Valves Employed for
Drawing Off Liquids.
We, EDWIN JOHN JONES, of 9, High Street, Wolverhampton in the County of
Stafford, merchant, and THOMAS JOHNSON, of Dudley Street, Bilston, in the said
County, brass founder, 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, reference being had to the accompanying drawings
and the letters of reference marked thereon (that is to say):-
This invention consists, chiefly, in the application, to the description of taps and
valves named in the title, and which are fixed for use direct to vessels containing "
liquid to be drawn off, of simple and efficient strainers for preventing any particles
of solid matter, except those which are very minute, from passing through such
taps and valves, such strainers being so constructed and fixed that they may be
readily removed to be cleansed, and afterwards replaced.
The tap or valve fitted with a strainer according to this invention, bas the usual
tubular part which enters within the liquid to be drawn off. Such part is
perforated in the usual or any convenient manner. The back end of this tubular
part is closed by means of a screw plug readily removable at pleasure; and the
bore of the tubular part is made parallel from the back end to a short distance in
advance of the perforations. A stud or pin is cast or fixed within the bore of the
tubular part in position somewhat in advance of the perforations, and a cylinder of
wire gauze, or of finely perforated sheet metal, or of other suitable construction,
forming the strainer, is inserted within the parallel part, and maintained in place
by means of the stud or pin and the screwed plug; and such strainer fits fairly
tightly within the perforated end of the tubular part, and thus all liquid passing
through the tap or valve must first pass through the gauze or fine perforations of
the sheet metal,
This invention will be clearly understood on reference to the accompanying
drawings, of which figure 1. is a side elevation of the usual description of tap
. employed for drawing off liquids, but having our improvements applied thereto;
figure 2 a longitudinal section through the perforated end of the tubular part which
enters within the liquid; figure 3 a corresponding section to figure 2, but shewing
a somewhat different application of our invention; and figure 4 a sectional plan
on line x of figure 3.
The same letters of reference indicate corresponding parts throughout the views.
a is a screw plug closing in the hinder end of the tubular part A which enters
within the liquid to be drawn off.
Referring now to figures 1 and 2, 6 6' etc. are perforations of the usual character
through the hinder end of the; part A. c is a transverse rivet or pin through the
part A in position forward of the perforations b b etc. B B is an open-ended
cylinder of wire gauze soldered along its longitudinal joint. This cylinder is made
to fit fairly tightly (but so as to be easily removable) within the hinder end of the
part A the bore of which is formed cylindrical from its back end to the rivet or

page_text: pin c. This gauze cylinder forms a fine strainer and prevents any but the most
minute particles from passing into the bore of the part A. The strainer B B may
be readily removed for cleansing by first unscrewing the plug a.
Referring now to figures 3 and 4, 61 61 etc. are enlarged perforations through the
binder end of the part A, in lieu of the small perforations shewn at figures 1 and 2.
The gauze cylinder is omitted in these views for convenience of illustration. The
object of this modification is to lessen the liability of the perforations being choked
up by seeds, particles of hop, or other solid substances, in comparison with the
smaller perforations shewn by figures 1 and 2, and which are usually employed.
The employment of a gauze cylinder similar to that shewn at B B, figure 2,
enables us to employ the large perforations shewn by figures 3 and 4.
Instead of soldering the joint of the gauze cylinder it may be left open, in which
case it is preferred to form the cylinder of a larger diameter than the bore of the
part A, and with a wide open joint, so that it. has to be sprung into its place and
consequently tightens itself firmly against the interior of the perforated part in
which it is placed. In this case one side, preferably the top side, of the part A is
unperforated and the strainer is placed with its open joint along the unperforated
part. In figure 3 the part A is shewn unperforated on its upper side for the
purpose of receiving the unjointed gauze strainer.
•
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim in respect of taps and valves employed for drawing off liquids, is :-
1. Strainers within the perforated ends of such taps and valves, substantially as
described and shewn, and for the purpose set forth.
2. The combination, with a strainer B B within the perforated part A, of a
screwed plug c and a stop at the forward end of the strainer, substantially as
described and shewn, and for the purpose set forth.
3. The combination, with the enlarged perforations through the part A sub-
stantially as described, of a strainer within such perforated part, substantially as
described and shewn, and for the purpose set forth.
