ALFRED GUNTHORPE, of 12, Queen's Row, Westmoreland Road, Walworth, and
BERNHARD HENOCH, of 1, Addington Cottages, Addington Square, Camberwell, both
in the County of Surrey. " IMPROVED APPARATUS TO BE USED IN CONNEXION WITH
THE DELIVERY PIPES OR SPOUTS OF BEER ENGINES, TAPS, COCKS, AND OTHER SIMILAR
APPLIANCES."
This apparatus is to be used for the purpose of decreasing or preventing the
waste or afterflow of liquor which frequently occurs in connexion with delivery
pipes or spouts of beer engines, taps, cocks, &c., and is constructed in the following
manner: A small piece of metal or other tube of the necessary length and
dimensions is made and fitted so as to be attached by a screwed thread or some
other simple means to the nose or more convenient part of the spout, tap, cock, &c.;
this tube is cut or grooved out at the top so as to allow of the valve or interior
wings dropping into their respective positions, and the whole surmounted by a small
ring, which sliding into the top of the outer tube prevents the wings from shifting
out of their place. The valve or interior wings are constructed in the form of two
diagonal segments of a short tube, the upper edges of which are more or less thicker
than the lower portion, so as to give additional power and rapidity of action as may
be required; these wings are also provided at each side with a small pin or ear by
means of which they are suspended inside the firstnamed tube or casing; their con-
struction and action may be readily understood by reference to Drawing, Figure 2.
When the wings are thus suspended and the ring aforementioned placed in position,
the valve is complete and ready for use, see Drawing A, Figure 2; its action when in

page_text: use may be thus described:-When the full pressure of the liquor comes in contact
with the valve it immediately opens, allowing a free exit to the liquor, see Drawing
D, Figure 2, and upon the removal of the aforesaid pressure the valve closes, see
Drawing E, Figure 2, thus decreasing or preventing the waste or afterflow and
precluding the entrance of air into the pipes, spouts, taps, &c. Where the constant
pressure upon the valve is very heavy this valve is modified by making the interior
as follows: A thin web or division bar to which are hinged two semicircular wings
or flaps, these wings being retained in a horizontal position by a small spiral spring
which allows them to work from a right angled position with the web, see Drawing D,
Figure 1. When closed to one parallel with it, see Drawing E, Figure 1. When open,
this web or division bar with the wings attached is made to slide centrally into the
outer tube or casing beforenamed in lieu of the two segmental pieces beforementioned
and produces the same effect.
