TROYIDIONAL DIVIFICATIVA.
A New Locking Device for Automatic Apparatus for the Sale of
Liquids or Solids.
I, BRUNO WESSELMANN of Hamburg in the Empire of Germany, Manufacturer,
do hereby declare the nature of this invention, to be as follows:
This invention relates to a locking device applicable to automatic apparatus for
the sale of liquids or solids and essentially consists in the application of a bolt sus-
pended so as to swing at the bottom of the vertical coin-passage. This bolt when its
normal position rests with its free hook-shaped extremity in a corresponding slit
provided in the slide or lap, and by the falling gravity of the coin recedes from said
slit and allows the slide to be drawn out or the tap to be turned. In apparatus for
solid articles the free lower extremity of the bolt catches into a slit provided in
the slide and arranged below, and parallel to, the plane of oscillation of the bolt, the
length of the slit being determined by the recession of the bolt caused by the falling
coin. A second longer slit meeting the other at a right angle and lying in the
drawing-direction of the slide allows the latter to be drawn out on the bolt being
pressed aside by a descending coin. The slide is perforated so as to allow the coin to
fall into a receptacle underneath when the slide is drawn out.
With apparatus for supplying liquids the descending coin after releasing the bottom
end of the bolt from a lateral groove provided in the rear part of the tap stands first
edge-ways on a suitable projection of the latter. On turning the handle of the tap
for about 90 degrees the liquid flows through a tube extending downwardly from the
receptacle of the tap into the glass kept ready by the purchasing person. At the same
time the coin loses its support and slides down an inclined plane of the said projection
into the coin chamber.
By returning the handle of the tap into its original position, the apparatus is
re-adjusted for the next delivery.

COMPLETE SPECIFICATION.
A New Locking Device for Automatic Apparatus for the Sale of
Liquids or Solids.
I, BRUNO WESSELMANN, of Hamburg, in the Empire of Germany, Manufacturer,
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 a new locking device applicable to automatic
apparatus for the sale of liquids or solids.
Referring to the accompanying drawings, Sheet I and II.
Fig. 1 is a vertical section along line A B, Fig. 3.
Fig. 2 a vertical section along line C. D, Fig. 3, and
Fig. 3 the top view of the delivery slide of the improved device as applied to an
automatic apparatus for the sale of solids, while
Figs. 4 and 5 are vertical sections of an automatic apparatus for the sale of liquids
showing the new locking device respectively in side view and partial section, and in
rear view.
The coin of predetermined value, on being introduced into the apparatus Sheet I,
first passes an inclined passage and subsequently descends the vertical coin passage f,
thereby pressing aside the bottom end of an oscillating bolt R, which forms on one

page_text: side an extension of this passage, and allowing the delivery slide to be drawn out with
the article purchased.
In the apparatus illustrated on Sheet II, the descending coin releases a tap instead.
of a slide, and allows the same to be turned for 90° and deliver the liquid. The spiral
spring g connects the oscillating lever R with the opposite stationary guide rail. P is
a metal plate, provided with a slitz and an opening a, and sunk into the wood of the
slide. are guidings secured to the rear wall of the apparatus and serving to prevent
the slide from taking along more than one piece in the case of tablets or other
flat articles. kk, Figs. 4 and 5, signify the tap attached to the bottom of the
liquid reservoir b, the rear end of the tap being clongated and fitted with a half-
slanted stop d having a recess n, into which catches the toothed-shaped lower
extremity of the oscillating bolt. E is a receptacle for refused coin, while the coins
actuating the apparatus are received into the box F.
The device for the sale of solids works as follows:
When the apparatus is ready for use, the short downwardly projecting extremity
of the bolt R rests in the lateral recess 1 of the slit z. The descending coin, after
deflecting the lower end of the bolt, assumes a vertical position on the rims of
the opening a of the plate p, while the part 2 of the slit z is ready to be passed
by the bolt, that is to say the slide is released. On pulling out the latter, the coin
falls through the widening of the opening a into the coin chamber provided underneath.
The length of the slit z depends on the size of the article to be sold.
In the apparatus for the sale of liquids, Sheet II, the descending coin, after
deflecting the tooth-shaped extremity of the bolt, settles in a vertical position on
the part d. On turning the latter by means of the outer handle for 90°, the liquid
contained in the hollow space of the tap flows through the discharge pipe pro-
vided underneath into a glass or vessel presented by the purchaser, and the coin,
deprived of its support, slides down the slanted part of the stop d into the coin chamber.
The apparatus is provided outside with two suitable projections determining the
angle of revolution of the tap-handle and bearing respectively the indications:
open" and "closed." The handle may however" also be returned to its closed
position by means of a spring or other suitable contrivance.
[6
If, in lieu of the tap & a stationary hollow cylinder is horizontally arranged at the
bottom of the receptacle b, which cylinder contains a second movable cylinder with
openings corresponding to those in the inner part of the tap, also solid articles can be
delivered by this apparatus, for instance little rolls or parcels. In this arrangement,
the articles fall through a tube communicating with the stationary cylinder from the
receptacle into the inner cylinder, whence they fall, on turning the latter for 90
or 180°, through a corresponding aperture provided at the bottom of the stationary
cylinder into a receptacle from which they are taken by the purchaser.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
In an apparatus for the automatic sale of solids or liquids.
1) The application of the locking device consisting, in apparatus for solids, of an
oscillating bolt R actuated by the falling coin, in combination with a slit z provided
in the slide, and, in apparatus for liquids, of an oscillating bolt R as above, in
combination with a notch n provided in the rear part d of a hollow tap, substantially
as set forth.
2) In combination with the device referred to in claim 1), for solids, the application
of the slide having an aperture a and slit z, and for liquids the application of the
hollow tap-portion provided with the half-slanted stop d for the purpose of
delivering the purchased article, substantially as set forth.
