COMPLETE SPECIFICATION.
A New or Improved Apparatus for Delivering Stated Quantities of
Liquid, Coin-freed Release Mechanism being also applicable to
same.
I, JOHN GRINHAFF of Swadlincote Burton-on-Trent, Gentleman, 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 a new or improved apparatus for delivering definite
quantities of tea, coffee, or other liquids and means are also provided for freeing same
by means of a coin so that an attendant is not necessary.
The object of my invention is to provide apparatus which upon operating a handle
will deliver stated quantities say half a pint or pint, of tea, coffee or other liquid
which will be found extremely useful in coffee houses and the like, also for bottling
liquids or for dividing it into definite quantities, and further by the coin-freed
mechanism tea, coffee or the like could be delivered at various parts without an
attendant being necessary.
In carrying my invention into practical effect I provide a containing vessel of
suitable size and provided with a pipe leading from the bottom of same to the
measure which is a cylindrical vessel of such a size as to hold the exact quantity
of liquid required to be delivered, and is furnished in front with a delivery pipe,
which, as well as the pipe leading from the containing vessel to the measure, is
furnished with a stop-cock. The two stop-cocks of the aforementioned pipes are
each attached to one end of a short lever, the said levers being loosely pivoted to a
draw bar, furnished with a knob at its extremity, so that upon pushing the draw bar
in the cock in the leading pipe is opened, while that of the delivery pipe is simul-
taneously closed thereby enabling the liquid within the retaining receptacle to flow
through the said leading-pipe and fill the measure, the rod being left in that
position a sufficient length of time to enable the measure to be filled. When this
has been accomplished, the rod is pulled out thereby closing the cock in the leading
pipe, and simultaneously opening that in the delivery tube and delivering the
quantity of liquid contained in the measure.
The said measure may be provided with a glass front in order that the operator
may see when it is full.
I may
further employ any well known mechanism for locking the draw bar the
said mechanism to be released by the weight &c. of a coin so that my improved
apparatus may be operated automatically.
In order that my invention may be more fully understood I will now proceed
to describe same with reference to the accompanying drawings in which
Fig. 1 is a side view of my improved apparatus with the case in section, Fig. 2
being a front view of same within the case,
Fig. 3 is an end view of a form of coin-freed release which may be employed
and Fig. 4 is a side view of same.
My improved apparatus consists of the containing receptacle C connected by
means of the leading pipe p to the measure m the said measure being furnished
near the front of same with a delivery pipe p¹ both pipes being furnished with
stop-cocks ss which are attached to the ends of short levers a a' the said levers being
connected together by the rod the end of which is pivoted to the draw rod
furnished at its extremity with the knob n.
Upon pushing the rod r in, the cocks is opened, and the cock s' simultaneously
closed by means of the levers a a' so that the liquid within the container flows

page_text: through the pipe p to fill the measure m and when this is effected the rod r is again
drawn out thereby closing the cocks and simultaneously opening the cock s¹ so that
the liquid contained within the measure is thereby delivered.
I do not restrict myself to any particular form of coin-freed mechanism but
Figs. 3 & 4 show one form which I may employ which consists of a weighted lever !
centrally pivoted at a the end b being weighted and entering a nick or recess formed
in the rod so that it is impossible to operate the said rod until the end of the lever
is raised which is effected by causing a coin to pass down a suitable shoot S when
it comes into contact with the end. of the lever and raises the part 6 just clear of
the nick when the said end comes into contact with the catch c the lever then being
in the first position shown in dotted lines in Fig. 4, the coin resting upon the other
end of the lever and only about half of it projecting below the end of the shoot
so that it is impossible for the coin to 'fall off the end of the lever, the said rod r
being also free to be operated. Upon pushing the rod r in the cocks s and s¹ are
operated as hereinbefore described and the catch e is pushed away clear of the end
of the lever thereby enabling the latter to still further rise until the end 6 comes
into contact with the stop t (as shown in the second position in dotted lines in
Fig. 4) when the coin falls from off the end of the lever thereby causing the
latter to assume its normal or horizontal position the end 6 resting upon the rod
ready to drop into the nick or recess in the draw rod r when the latter is again
pulled out for the delivery of the liquid, thereby locking the said rod and preventing
it being operated until the lever is again raised by means of a coin.
с
My improved apparatus may be enclosed in any suitable case C¹ and may be
furnished with a door d in a suitable position so as to enable a lamp or gas burner
to be placed under the container C when tea, coffee, or the like,
required to be
kept warm, and further a pipe g leading from the container C to the measure m may
be employed for the passage of steam to keep the latter warm.
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 new or improved apparatus for the delivery of definite quantities of
liquid consisting of the container C, measure m, supply and delivery pipes p p¹ with
their cocks levers a a¹ and rods arranged, tructed and operated
substantially as described and shown and for the purpose specified.
".
2. In combination with the apparatus above claimed the use of any well known
coin-freed mechanism for operating the same automatically substantially as described
and for the purpose specified.
Dated this 9th day of March 1894.
