Improvements in Apparatus for Delivering Liquids, and Registering
and Checking the Sale thereof.
I, HERMANN OEHMS, of 44, Pallisadenstrasse, Berlin, in the Empire of
Germany, Merchant, 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 :-
This invention relates to a checking or registering apparatus for use in the sale
of liquids such as schnapps, wine, beer, petroleum, and the like. The basis of
the invention consists in producing at each sale, on a continuously running band,
a sign which corresponds exactly to the amount of liquid sold. This new appliance
affords an absolutely secure protection against frauds which have hitherto been
very frequent and almost impossible to determine, and the accompanying drawing
shows the apparatus in the form suited to the sale of schnapps.
Figure 1 is a front view of the checking apparatus ;
Figure 2 is a plan view; and
Figure 3, a side view;
Figure 4 shows a vertical section of the measuring cylinder with inlet and outlet
cocks;
Figure 5 shows to a smaller scale the two final positions of the lever mechanism
which actuates the inlet and the outlet cocks.
The cylinder a which serves for measuring the liquids stands with its pedestal b
on a table c having feet d. Inside the cylinder a is a sliding piston e by which the
liquid is drawn into the cylinder through the cock fand delivered through the
cock J.
The rod of the piston e has a crossbar h at its upper end, and the free end of a
strong spiral spring i engages this crossbar so that the rod of the piston e has
always a tendency to ascend into its highest position. In order to depress the
piston e a hand lever which is journalled in the fixed bracket k is depressed.
This lever also serves for actuating the cocks fand g by means of levers m n
and links m¹ n. A perforating wheel o pivotted in the crossbar h records the
movements of the piston e on a paper band arranged in the box O, and the
arrangement is such that the paper band is moved a little for each stroke of
the piston. This movement is also effected by the hand lever 1. The axle r
turning in the bracket k on which axle the lever I turns, carries a ratchet wheel p
and a pawl or click q on the hand lever / engages into this wheel p.
The movement of the ratchet-wheel p and axle ris transmitted by means of
bevelled gearing 1 and 2 to a spindle s and from this spindle by means of toothed
wheels and 2 to a spindle o¹ which turns in the box O and moves the paper
band. The paper band is wound off a spindle o' inside the box on to the spindle o'.
The box O is provided with a suitable slot in which the perforating wheel o can
move according to the rise and fall of the piston. As the paper band cannot be
moved when the perforating wheel is in it, the ratchet wheel p and pawl q will
consequently be arranged as seen in Figure 1, so that the wheel p will only be
moved after the hand lever has been moved a considerable distance in the
direction of the arrow. The cocks fand g are so arranged that the cock f is closed
when the handle is in the position shown in Figure 1 and the cock g will then be
partially opened. When the handle is moved in the direction of the arrow the
cock g is then further opened and is subsequently gradually closed. The cock f

bar or rack t pivotted to the table c and acted on by a flat spring c¹ engages with.
the crossbar h; by this means the piston e cannot rise under the action of the
spiral spring until the rack t be moved out of engagement with the crossbar h
which is effected when the cock has been completely shut and the cock f partially
opened. For this purpose a hent arın t¹ is fastened to the hand lever land this
arm will engage and move the rack out of engagement with the cross bar at a
suitable moment when said hand lever is pushed upward by hand, and the spiral
spring can then press the piston e upwards. The measuring cylinder a is then
filled by the liquid flowing from the pipe f.
i
When the piston e has reached its highest position, the perforating wheel o will
be out of contact with the paper band. When the lever is further moved the
pawl will cause the paper band to move in the manner described. If the lever /
be pulled down the cock fis closed and the pawl q will slip over the ratchet
wheel p. In this movement the bent arm t¹ first comes against a pivotted piece t²
on the end of the toothed bar or rack t and this piece t2, being capable of turning
in the same direction in which the hand lever now moves, allows the arm t' to pass
over without moving the toothed bar t. As soon as the bent lever t' has moved
over the toothed bar t, the piece t2 will then turn back into its original position
under the influence of a small flat spring. When the bent arm this moved in the
opposite direction, by the lever I being moved in the direction of the arrow, the
piece t cannot be turned owing to its construction as will be seen from the drawing,
and the toothed bar or rack t will therefore be turned on its pivot and moved by
the arm t' out of engagement with the crossbar h in order to allow the piston e to
rise under impulsion of the spring i.
When the bent arm t¹ has passed the toothed bar t in a downward movement of
the lever 1, the cock fis sinut and the cock g commences to open and as soon as the
hand lever has reached the head of the piston rod, the cock g will then be so
far open that the liquid in the cylinder a can pass out through the nozzle g¹ on
the piston being depressed by a further pull of the hand lever l. On the lever
being further depressed the piston is similarly depressed but the cock g remains
open. The quantity of liquid passing out will correspond exactly to the amount of
travel of the piston e, that is according to the distance the lever is pulled, after it
has commenced to depress the piston and the distance traversed by the piston will
be marked by means of the perforating wheel on the paper strip which is
contained in the box O. It will therefore be clear, without further explanation,
that by means of the adjacent lines on the paper it can be seen how often, and
what quantities of liquid have been sold.
In hotels it is customary to give for the same price larger quantities of liquor in
the "outdoor" trade than in the "indoor" trade. By the respective lengths of
the individual markings on the paper band it can therefore be seen whether the
sale has been for indoors or otherwise, as for each price and for each kind of sale
the lever would be pulled down to a different extent, thus scoring the paper band
with a vertical line, the length of which would indicate the quantity and price of
the liquid sold. For this purpose the band is ruled with continuous lines running
horizontally, the spaces between certain of these lines representing different prices
and quantities. Supposing that indoors the prices are a penny, twopence and
threepence, and outdoors twopence and four pence, there will then be five different
lengths of vertical scorings to be made to suit the five different kinds of sales each
of which requires a longer pull of the lever than the others and the paper strip is
consequently first correspondingly divided by means of five different continuous
horizontal lines into separate sections.
When the paper band has been wound off, the corresponding prices can be
written alongside the different lines and the total can at once be reckoned up.
If other appliances or mechanism be made use of, instead of the arrangement of
levers and intermediate parts herein before described, the essence of the invention
will yet remain the same, which is that the movements of the piston be exactly
