A Novel or Improved Appliance to Prevent the Ingress of Insects
into Taps used for Beer and other Liquids.
I, HERBERT MEYNELL, of the Firm of Meynell and Sons, of Montrose Street,
Wolverhampton in the County of Stafford, Brass Founders, do hereby declare the
nature of this invention to be as follows:-
In using taps for beer, and other liquids of a character which attracts flies and
other insects, it is frequently found that the flies and other insects crawl up into
the noses of the taps and are thus washed down into the jug or other receptacle
into which the liquid is drawn from the tap.
Now, this invention has for its object a novel or improved appliance which may
be readily attached to and detached from a tap for use in preventing the flies and
other insects from crawling up into the nose of the tap.
An appliance constructed according to this invention, for the purpose stated,
consists essentially of a strainer carried by, or formed as part of, a suitable
mounting, and of means by which such mounting may be readily and detachably
fixed to the tap.
According to a convenient means of carrying out the invention in practice, in
cases in which provision can be made upon the nose of the tap for receiving the
appliance, the appliance consists of a socket or ring having a projecting milled
edge and an inwardly projecting flange at one end, and of a strainer of wire gauze
or other suitable material formed with a flange or portion which beds against the
inner face of the inwardly projecting flange aforesaid, and the edge of the mounting
at the opposite end thereof to the inwardly projecting flange is formed with
L-shaped slots which engage with studs projecting from the nose of the tap and
thus form therewith a bayonet joint. The strainer is, preferably, formed with a
portion of hemispherical or analogous shape which projects through the hole which
is surrounded by the inward flange, and the flange of the strainer is held between
the nose of the tap and the inward flange of the mounting; and in order to prevent
the liquid from leaking upwards between the nose of the tap and the surrounding
portion of the mounting, it is preferred to place a rubber ring between the flange
of the strainer and the nose of the tap, or otherwise in position within the
mounting so as to surround the nose of the tap when the mounting is fixed in
place.
According to another modification, the socket may be screwed upon the nose of
the tap.
According to a modification which is suitable for application in the case of taps
which are not specially prepared to receive the appliance, the appliance may be
fixed to the nose of the tap by means of a bridle-piece which passes over the
top of the tap and is tightened up by means of a screw.
A convenient form of the appliance, however, for use with taps which are not
specially prepared to receive it, consists in fixing within the socket a rubber
nipple of such internal diameter that as it is pushed up over the nose of the tap it
tightens itself therearound. This nipple may either be formed to project from the
socket, or may be contained entirely within the socket. In either case, the inner

end of the rubber nipple may bed against the flange or corresponding part of the
strainer.and thus keep the strainer in place within the socket.

A Novel or Improved Appliance to Prevent the Ingress of Insects
into Taps used for Beer and other Liquids.
I, HERBERT MEYNELL, of the Firm of Meynell and Sons, of Montrose Street,
Wolverhampton in the County of Stafford, Brass Founders, 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 :-
In using taps for beer, and other liquids of a character which attracts flies and
other insects, it is frequently found that the flies and other insects crawl up into
the noses of the taps and are thus washed down into the jugs or other receptacles
into which the liquid is drawn from the taps.
Now, this invention has for its object a novel or improved appliance, which may
be readily attached to and detached from a tap, for use in preventing the flies and
other insects from crawling up into the nose of the tap.
An appliance constructed according to this invention, for the purpose stated,
consists essentially of a strainer carried by, or formed as part of, a suitable
mounting, and of means by which such mounting may be readily and detachably
fixed to the tap.
. A convenient means of carrying out the invention in practice, in cases in which
special provision can be made upon the nose of the tap for receiving the appliance,
is illustrated by Figure 1. The tap A is shewn in side elevation, except that the
nose thereof is shewn in section; and the appliance B is shewn in section as affixed
to the nose of the tap. The appliance is shewn to consist of a socket or ring a,
having conveniently a projecting milled edge 6 to facilitate turning it in making
the joint with the tap, and an inwardly flanged portion c at its lower end; and of
a strainer d, which may be of wire gauze or other suitable material, formed with a
flange or portion e which may bed against the upper or inner face of the flange c,
but beds preferably against a leather or rubber washer f which itself beds upon
the flange c. A leather or rubber washer g is, preferably, placed upon the upper
face of the flange or portion e to prevent leakage between the nose of the tap and
the surrounding portion of the socket a, and the washers f and 9 are, preferably,
cemented to one another and the flange or part e of the strainer by any suitable
cement, such as glue or rubber solution. L-shaped slots, such as h (shewa by
broken lines only) are formed in opposite sides of the socket a, and engage
with studs projecting from the nose k of the tap, and thus form therewith a
bayonet joint. When the appliance is fixed to the tap, the end of the nose of the
tap presses upon the washer g, and the flange or portion e of the strainer is securely
beld in place. The upper faces of the studs, and the upper edges of the sideway
portions of the slots, are preferably somewhat inclined to facilitate making the
joint, and to ensure that it will be tightened up somewhat as the sideway portions
of the slots are caused to engage with the studs. The strainer d is, preferably,
formed with a portion of hemispherical shape, as shewn, (or of analogous shape)
which projects through the hole which is surrounded by the flange c.
An appliance such as above described may be screwed upon the nose of the tap,
instead of being attached thereto by means of a bayonet joint as described.

page_text: A convenient form of the appliance, for use with taps which are not specially
prepared to receive it, and indeed the form in which I prefer to use it, is
illustrated by Figures 2 and 3.
Figure corresponds to Figure 1, and Figure 3 is an elevation of the
appliance. The appliance has a strainer d corresponding to the strainer already
described. The flange or portion e of the strainer is in position between leather or
rubber washers fand g, which in this case also are, preferably, cemented to one
another and to the part e of the strainer. The lower washer beds upon an
inward flange c of a socket a as in the modification above described. The socket
is in this case preferably made of sheet metal, such as sheet brass. Instead,
however, of the washer g being pressed upon by the nose of the tap as in the
arrangement shewn by Figure 1, such washer is pressed down by a portion / of a
rubber nipple which is inserted between an inward flange m at the top of the
socket and such washer g. The flange m is spun or turned in after the strainer
has been placed within the socket. The nipple has a portion n which projects up
through the hole which is surrounded by the inward flange m, such portion
preferably tapering smaller in diameter upwards both inside and outside, as shewn.
The appliance is affixed to the nose of the tap (which usually enlarges somewhat
towards its end, as shewn) by stretching the portion n of the nipple thereover. The
portion of the nipple may be inserted within the socket a after the flange m
thereof has been spun or turned in.
A modified form of the appliance illustrated by Figures 2 and 3 is shewn, in
vertical section, by Figure 4. The main difference between this appliance and
that illustrated by Figures 2 and 3 is that the socket a is made deeper, and the
nipple n is contained entirely therein. The nipple is of sufficient thickness at the
top to ensure that its outer edge will be retained by the flange m.
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. An appliance to prevent the ingress of insects into taps used for beer and
other liquids, which comprises a strainer of wire gauze or other suitable material
in combination with a suitable mounting and means by which the same may be
readily detachably connected with or joined up to the nose of a tap, substantially
as described.
2. An appliance to prevent the ingress of insects into taps used for beer and
other liquids, which comprises a strainer fitted to a socket, and an annular elastic
connector by means of which the socket may be detachably connected with or
joined up to the nose of the tap, substantially as described.
3. An appliance to prevent the ingress of insects into taps used for beer and
other liquids, constructed substantially as described and shewn, according to
different modifications, by the drawings herewith.
