Improvements in Beer Engines and like Apparatus.
I PAUL EDME THEODORE DARDELLE of No. 2 Kirn Road Ealing. Dean in the
County of Middlesex Engineer do hereby declare the nature of this invention
to be as follows:-
:-
My invention relates to means, applicable to beer engines and the like, for checking
and registering the value of the liquor dispensed by them. As an example, I will
describe the application of my invention to a beer engine capable of drawing by its full
stroke half a pint which may have the value of twopence, and by its half stroke, a
quarter of a pint of the value of one penny. In the handle of the beer engine I fit a
spring rod which when depressed by the finger of the operator moves a stop which
prevents the handle from making more than half its stroke and therefore limits the
draught to one quarter of a pint. When the rod is not so depressed, the handle can be
pulled fully over and the engine delivers a draught of half a pint. On a segment
moved by the handle as it turns upon its pivot, I make a cam path against which is
pressed by a spring a roller mounted on the lever of a pawl which engages with a
ratchet wheel. This ratchet wheel moves directly an index and by suitable gear other
indices of a counter indicating on dials pence shillings &c. When the handle is
pulled only half way the cam causes the pawl lever to make only one stroke, the first
index marking one penny, but when the handle is pulled fully over the cam in its
forward movement causes the pawl lever to make one stroke, and in its return
movement to make a second stroke, the counter thus being made to record two
pence.
In order to prevent the engine from being improperly worked by a series of short
to and fro strokes that would not be sufficient to move the counter, I provide in the
segment moved by the handle a slot in which the pin of the pump rod is free to move,
and on the segment I pivot a spring tappet which, when the handle is moved fully up
engages this pin and causes the pump rod to make its stroke along with the segment
as the handle is pulled over. But should the handle not have been moved fully up,
this tappet lever is in such a position that it is pushed aside by its spring and fails to
engage the pin of the pump rod so that, on pulling over the handle, the pump is not
worked.
Also if after pulling the handle partly over and working the pump so far as to
cause the counter to mark one penny, the handle should be pushed partly back taking
the strain off the tappet lever, that lever is moved aside by its spring and so disengages the
pump rod from the segment and consequently the handle when it is moved to and fro,
fails to work the pump. The pump cannot again be worked until the handle is fully
raised and the tappet lever is thereby brought again into position to engage the pin of
the pump rod.
Although I have described the invention as applied for half pints and quarter pints
represented by a penny and two pence respectively obviously it could be applied to
other measures and other money values.

COMPLETE SPECIFICATION.
Improvements in Beer Engines and like Apparatus.
I, PAUL EDME THEODORE DARDELLE of No. 2 Kirn Road Ealing Dean in the County
of Middlesex Engineer, 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 means, applicable to beer engines and the like for checking
and registering the value of the liquor dispensed by them. As an example, I shall
describe the application of my invention to a beer engine capable of drawing by its
full stroke half a pint which may be of the value of two pence, and by its half stroke,
a quarter of a pint of the value of one penny. The accompanying drawing is a vertical
section of the upper part of a beer engine with apparatus according to my invention
applied thereto. A is the handle which is connected as usual to a segment B having
an arm that is pivotted at C on the fixed framing. On a projection from this arm is
pivotted a bell crank D pressed by a spring. On one arm of the bell crank D bears a
sliding arc E, on which bears a sliding rod F. This rod passes up the handle A and
terminates in a button f. When the handle A is pulled over a lateral projection d on
the bell crank D escapes a shoulder G projecting from the fixed framing and the
handle is permitted to make its full stroke: But should the operator desire to give the
handle only half its stroke he by pressing with his thumb on the button depresses
the arc E and moves the bell crank D into such a position that its projection d meets
the shoulder G when the handle has made half its stroke and thus stops the handle
from being farther moved.
On the lower limb of the segment B is formed a protuberanco b against which bears
a roller mounted on a spring lever H. This lever is connected to the pawl and
ratchet of a counter of any known kind situated in any convenient part of the framing:
When the handle A is pulled quite over, the-whole length of the protuberance b passes
the roller and consequently the lever H is caused to make a to and fro stroke, and again
when the bandle A is moved back the lever H is caused to make another to and fro stroke.
The counter index worked by the lever H is then, moved over two divisions representing
two pence as the value of the liquor delivered by the full stroke of the beer engine.
Should the handle A be stopped at half stroke as above described then the lever H will
make only one to and fro stroke moving the counter index only one division repre-
senting one penny the value of the liquor delivered by the half stroke of the beer
engine. The protuberance 6 may be stepped as indicated by the dotted line, the first
step corresponding to half stroke of the handle A, the second step corresponding to the
full stroke. Hitherto I have assumed that the pump rod is permanently connected to
the segment B, and consequently that the pump rod will always move in obedience to
the handle A. If this were so, the operator having partially moved over the handle A
so as to bring the roller on to the protuberance b, might go on giving a series of
short strokes delivering liquor without farther moving the lever H and consequently
without working the counter. In order to prevent this from being done I do not link
the pump rod K permanently to the segment B, but fit the pin of the pump rod to
slide in a curved slot L, and I mount on the segment B a spring lever M having a
projection in which comes under a fixed stop N when the handle A has made its full
back stroke, the nose m' of the lever M being thus directed towards the head k of the
pump rod K. When now the handle A is pulled over, the nose m¹ bears against the
head and the pump rod K is raised. But should the operator, instead of continuing
the down stroke of A make a partial back or up stroke, the nose m¹ is at once freed
from its frictional hold on k and the lever M being pushed upwards by its spring, the
nose m³ no longer acts on k, consequently the pump rod K is no longer moved by
the movement of the handle A. As the projection m comes under N only when the
handle A is moved fully back, the pump rod K cannot be worked by the handle when.
the handle starts from any other than its upright position.

page_text: Obviously when it is not desired to work the beer engine with half strokes as well
as with full strokes, the sliding rod F, arc E and lever D may be dispensed with.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare what I
claim is
1. In combination with the handle of a beer engine and the segment moved thereby
a lever moved by a protuberance on the segment and connected to a counter arranged
to register the strokes of the handle substantially as described.
2. In combination with the handle, segment and counter gear of a beer engine, a
curved slot in the segment receiving the pin of the pump rod and a spring lever with
projection acted on by a stop in such manner that the nose of the spring lever
engages the head of the pump rod only when the handle and segment have made their
full back stroke, substantially as and for the purpose set forth.
3. In combination with the handle and segment. of a beer engine, a sliding rod in
the handle, a sliding arc and spring bellcrank lever with lateral projection so arranged
in relation to a stop that, on depressing the sliding rod the movement of the handle is
arrested at half stroke, substantially as described.
