page_text: gentle friction in the cylinder. It is provided with a hollow rod A³×, which passes
through the lid of the cylinder; this rod has a cap A, which serves as a abutment
and limits the stroke of the piston. A little hole or vent A' of about 2 millimetres is
pierced in the piston, to afford a passage for the liquid. On the lid A³ is fitted a
curb A into which passes an adjusting screw A', provided with a counter-nut A°*.
This curb A is provided with a boss A10, which serves as the axis of a forked
lever A1 (Figures 7 and 8), provided with a spring A¹. This lever is worked by the
cap A of the piston rod. The liquid to be distributed enters, as we have already
said, into the cylinder through the tube A, and passes through the hole or vent A' of
the piston A³ to reach the lower chamber of the cylinder. In consequence of the area
occupied by the hollow rod A³×, the pressure exerted upon the upper surface of the
piston A is less than that which is exerted upon its lower surface, and the piston will
rise in the cylinder under the pressure of the liquid contained in the lower chamber,
until it abuts against the adjusting screw A°. This screw, as will be seen, permits of
increasing or diminishing, at will, the lower capacity of the cylinder and consequently
the quantity of liquid to be delivered each time the apparatus works.
The liquid which comes out of the cylinder through the bent tube A³, enters
through a pipe soldered on to the bent tube B" above the valve B of the valve
box B.
The valve box B (Figures 9 and 10) consists of the body screwed on to the foot B'.
This arrangement permits of the box being placed in a suitable position. The box B
contains the valve B³, provided with an india rubber washer B and an axial rod B¹,
guided by metal bearings B and B. This valve B is governed by a lever B,
provided with a spindle B8, upon which is fixed a lever B', provided with a counter-
poise B10.
When the lever Be is lowered, it raises the valve B³, allowing a passage
for the liquid, which flows through the bent tube B2 and reaches the spout B.
When the apparatus is not at work, the lever B' rests upon a pawl (11 fitted upon the
lever-system C of the money box.
The money box, shown in Figures 2, 3, 11 and 12, consists of a cylinder C,
provided with its lid (which is hinged and which may be furnished with a padlock
or any other suitable fastening. The lower part of this cylinder has two ears which
serve to fix the box in the apparatus. The lid has an aperture C³, through which the
coins pass; this aperture is prolonged on the inside by a bent channel (Figure 11),
the object of which is to prevent the coins from being taken out of the box. Upon
the lid is fixed a plate C, bearing the vertical shoot C ending in a funnel Cx; also
the lever system C (Figures 3 and. 12). The shoot C is in two parts, easily taken to
pieces. In this shoot, a groove or slit is made, which the end of the lever C
enters. This lever is provided with a counterpoise C8, which permits of its being
regulated. It is fixed upon a little axis C, which has at one end an arm C10 provided
with a pawl C, and a spring C₁. On the pawl rests the end of the lever Be of the
valve box, when the apparatus is at rest as seen in Figs. 18 and 19. This lever B° is
guided by a curved guide (13 fitted upon the money box.
The coin, in falling into the shoot C, lowers the lever C, which at once rises again
in consequence of its counterpoise, but in descending it releases the lever B°, which
falls and raises the valve B³, affording a passage for the liquid, which comes out with
force through the spout B¹.
The pressure under the piston A³ of the distributing cylinder ceasing suddenly in
consequence of the outflow of the liquid under pressure, the piston falls abruptly.
The cap A then abuts against the lever A", which rocks and raises with its front
end the lever B, gearing it again with the pawl 0" of the detent. The valve B'
then promptly ceases, and the apparatus is ready to act afresh.
The relative positions of the three levers B A and C are shown in Figures 18
and 19, in elevation and in plan respectively.
Slide. The coins reach the shoot (of the money box after having passed through
a guide shown in Figures 2, 13, 14, 15, 16 and 17. This guide is fixed upon the
outer money plate M by the lug D'. It is provided on its face D¹ with two
apertures D and D³, as shown in Figures 15 & 17, Figure 14 shows an elevation of

page_text: the other face of the guide. Between the two plates or faces D1 and D', held
together by the screws D', the coins inserted in the apparatus pass, as shown by the
dotted lines in Figure 14. The lower side of the slide, upon which the coins roll, is
provided, in front of the apertures D2 D³, with little swing plates Du D¹³, sustained
by the balanced levers D D 10 moving about the axes D18 D₁ mounted upon a
support De fixed on the guide.
Figure 16 is a section from X' to X¹ of Figures 13 & 15. The distance D'
is millimetre less than the diameter of a 10 centimes piece.
The first swinging plate D" fitted upon the end of the lever D, is governed.by
means of its counterpoise in such a way that the proper coins pass over the plate Du
without making it descend, while they make the plate D descend; and passing
through the aperture D³, they fall through the funnel Cx into the box, thus making
the apparatus work. The funnel (× is placed between the shoots H and H¹.
Coins lighter than the proper one pass over the two plates without making them
oscillate and come out through the end of the slide into the shoots H and H and
thus into the trough S placed on the outer face of the apparatus (see Figure 17).
Coins heavier than the proper one set the first swing plate D" in action and also
reach the trough S through the shoots H' and H. In our apparatus, these shoots
are not absolutely straight, as might be imagined from Figure 17. They are
arranged in such a way as to leave room for the parts which have to lie between
them.
The arrangement of this slide with swing-plates is such that the apparatus can
only work when the proper coin is inserted into it. Any other coin placed in the
apparatus passes through to the trough S and is thus returned to the public.
Figure 17 in perspective shows clearly the arrangement of the slide and its shoots H
and H. It is very easy to arrange the apparatus so that it will act on the insertion
of any coin. It is sufficient for that purpose to alter the proportions of certain
parts of the slide D, and to regulate suitably its lovers and the lever C" of the
money box.
In order to show when the liquid has been exhausted in the barrel or reservoir O,
and to prevent the coins then inserted by the consumer from remaining in the
apparatus we adopt the following arrangement :-
The float-box F, (figures 2, 4 and 5) placed under the barrel, consists of a cylinder E',
with a lid Escrowed on, provided with two jointed bent tubes E3 and E and a
projecting part Es. At the top of the box is a boss E in which the rod E7 of the
float E slides. In the projecting part E' is arranged a spindle E which passes
through a bearing E. This spindle E' carries a lever E", which is jointed to the
rod E. Upon the spindle E is fixed externally a lever E¹. The end of this
lever E projects under the end of the lever Dº of the slide. When the liquid is
exhausted in the barrel and consequently in the cylinder E', the float Es descends,
lowering the lever E" and raising the lever E" which in turn raises the lever D'
governing the plate D₁ of the coin guide.
This plate D remains lowered until fresh liquid is introduced into the apparatus,
and all coins which are put into it pass through the aperture D' and the shoot H¹
into the trough S, thus being returned to the consumer.
In order to show, at any moment, at a glance, the state of the apparatus and what
consumption there has been, we arrange a meter K, which registers the number of
times that the apparatus has acted. This meter is worked by the distributing
cylinder or otherwise in any suitable way. We have simply shown, in Figure 1 of
the accompanying drawings, the face of the meter, the mechanism of which is not
described and shown.
L (figure 1) is a tap supplying water at will. This water enters the apparatus in
any suitable way.
It is a matter of course that we in no way intend to limit ourselves to the
arrangements as described and shewn, which are capable of numerous alterations in
their details and workmanship.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. The mode of automatic delivery of liquids under pressure, upon the simple
insertion of a coin of any specified form.
2. The combination, for that delivery, of a delivery cylinder with lever, a valve
box with lever and a money box with its lever system.
3. The coin guide with swinging plates, by means of which the apparatus can
only work on the insertion of a coin of the specified form, and which enables any
other coin placed in the apparatus to be returned to the public.
4. The mode of optional regulation, by means of the special arrangement of the.
delivery cylinder, of the quantity of liquid to be served.
5. The combination, with an automatic liquid deliverer, of a float which perinits
of a coin introduced into the apparatus being returned to the consumer when the
liquid is exhausted.
6. The combination of this float with the coin guide.
7. The combination, with an automatic liquid deliverer, of a meter, registering the
number of times the apparatus has worked.
8. The automatic deliverer of liquids under pressure, such as we have described in
the present specification and shown in the accompanying drawings.
