Improvement in Pumps for Raising Cider and other Liquids.
1, HARRY CARR GIBBS of Pembroke Stores Bournemouth in the County of Hants,
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:-
The object of this invention is to construct pumps for raising cider and other liquids
containing acids in such a manner that the said liquid does not come in contact with
any metallic substance and to enable such pumps to be fitted to ordinary beer engines.
According to this invention 1 construct the barrel of the pump of glass having
vulcanite covers at each end thereof, the bottom cover has formed therein a seating for
the suction valve which valve is also of vulcanite: I attach further to the bottom
cover a vulcanite union and tail piece. The top cover I provide with a delivery port
or passage into which fits a vulcanite spout or tap and I further provide this cover
with a stuffing box and gland. The piston or bucket is made of vulcanite having the
delivery valve (also of vulcanite) therein. I prefer to pack the piston with a cup
leather held in place by a vulcanite nut. And in order that my said invention may
be the better understood I will proceed to explain the same with reference to the
accompanying sheet of drawings in which Fig. 1 represents elevation partly in section
of a cider pump for Licensed Victualler's use constructed according to my invention
Fig. 2 plan of same. Fig. 3 modification of the above as applied to engines fitted
with the pumps at some distance below the pulls.

stated. E. vulcanite tail piece. D. union. F. F. brass plates. G. G. bolts for clamping
the whole together. H. vulcanite spout. I. pump piston. J. packing leather.
K. delivery valve. L. piston rod. N. stuffing box. M. gland. 0.0. jointing washers.
P. see Fig. 3 brass frame for securing pump to counter or framing.
In Fig. 1 & 2 the screw bolts g. 9. g. of which there are three are prolonged upwards
and screw into the counter or bed plate the piston rods of both Figs. 1 and 8 being
attached to suitable pulls either direct or by means of connecting rods.
In the modification shewn at fig. 3 the liquid rises from the pumps through a pipe Q.
made of vulcanite or other innocuous material to the delivery spout. In pumps con-
structed as above the liquid raised thereby does not come in contact with metal the
only parts thereof in contact with the liquid being either glass or vulcanite.
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. The improved construction of pump for raising cider and other liquids sub-
stantially as described and shewn in Figs. 1 & 2.
2. The modification of the same shewn in Fig. 3.
