PROVISIONAL SPECIFICATION.
Improvements in Apparatus for the Automatic Sale of Articles.
I, BRUNO WESSELMANN of Hamburg in the Empire of Germany, Manufacturer, do
do hereby declare the nature of this invention, to be as follows:-
These improvements relate to a novel mechanism for the delivery of articles bought
from automatic apparatus and to a new device for disengaging or arresting the
delivery-mechanisın.
The mechanism for the delivery of the articles essentially consists of an axle
horizontally arranged in the upper part of the receptacle for the articles and provided
outside with a crank or handle. The interior part of said axle carries a nut adapted
to be moved forward and backward by means of a screw thread of high pitch according
to the direction in which the crank or handle is turned. With said nut is connected
hinge-fashion one extremity of a two-armed lever provided about the middle of the
receptacle, and seizing with its other extremity, extending nearly to the bottom of the
latter, a slide containing the article, by means of a suitable joint. Thereby the move-
ment of the nut is transmitted on an increased scale to said slide. On turning the
crank or handle for about 180 degrees the slide with the article is caused to project
outside the receptacle and the article to fall into a hollow chamber situated immediately
below the slide. The article can be only taken out of said chamber after turning back
the crank or handle.
The arresting device which is disengaged through the dropping of a coin into
the apparatus consists of a rod vertically suspended from joints below the above-
mentioned axle and having at its upper extremity a tooth and a fork serving to seize
the coin supplied. This rod is so balanced by means of an adjustable poise that the
tooth catching into a groove provided in the axle disengages the latter on dropping in
a coin of a certain weight.

COMPLETE SPECIFICATION.
Improvements in Apparatus for the Automatic Sale of Articles.
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:-
This invention relates to improvements in automatic sale apparatus and comprises
an improved contrivance for disposing of coins not having the predetermined value
and new devices respectively for disengaging the delivery mechanism and for the
delivery of the articles.
Referring to the annexed drawing,
Fig. 1 is a front view and partial section, and
Fig. 2 a vertical section of an apparatus provided with the above improvements.
Figs. 3 and 4 represent details thereof.
The box a encloses four separate spaces b c d e, b serving to receive coins of other
than the predetermined value, c contains the mechanism and d the material to be sold,
while e serves as a receptacle for the received correct coins.
The contrivance for the separation of coins of inferior size, provided within the
compartment b, consists of two superposed inclined guide rails and g connected at
their extremities and having a L shaped and U shaped cross section respectively.

page_text: Said rails lie approximately in the same plane at the aperture for the introduction of
the coin, while, in their continuation, the upper railf gradually deviates, thereby
causing the descending coin to assume an inclined position before reaching the
widened knee-piece A terminating at the bottom in a slit.
The compartiment c contains the device for respectively disengaging and arresting
the mechanism serving for the delivery of the prepaid articles. Said device consists
of the rod m vertically suspended by means of levers kk from the hinges 11 and
provided at its top with the annular bow i and the small fork . This rod is balanced
and held in a certain height by means of the adjustable counter poise n carried by the
angle lever k. The rod m has inside the bow a tooth-shaped extension o fitted
into a notch p of the shaft y which is provided at this place with a stop and is lodged
in the two opposite sides of the case having outside a handle r. By means of the
latter, the shaft can be tarned for 180° to the right and to the left, this movement
being determined by the pin s integral with the shaft and guided in a corresponding
cut of the bearing t.
The shaft q carries a worm and a loose nut u movably connected at the bottom
with the two-armed lever which is bifurcated below its fulcrum w and movably
connected with its lower extremities to the slide æ. The latter is displaceable in
grooves provided in the sides or the case and has in its front portion cuts or apertures,
the shapes and size of which depends on the nature of the article to be sold.
Closely below the slide is provided outside the receptacle y open above and serving
to receive the purchased article in the manner hereafter described.
The improved apparatus works as follows:
The coin introduced through the slot descends along the guide rails referred to
above and, if it is smaller than the slot that is to say than the prescribed coin, is
latterally thrown out into the chamber bowing to the above described relative position
of the rails, whereas, if it has the proper size, it arrives through the knee-piece h
direct between the shanks of the fork and presses by its own weight the tooth o
of the rod m out of the notch p, thereby releasing the delivery mechanism.
Subsequently the handle occupying the position indicated by dotted lines in Fig. 1,
is turned for 180° thereby causing the slide a to protrude from the case and drop
the purchased article into the receptacle y, while simultaneously the peg provided
on the shaft seizes the coin resting in the fork and throws it into the chamber e.
9
The purchased article cannot-or only with great difficulty-be taken out of
the delivery receptacle, unless the slide is returned into the case by turning the
handle back into its original position and thereby causing the tooth o to re-enter
the notch p by the action of the counter-poise n and the apparatus to be ready for the
next sale.
To preclude the introduction of a second coin during the above operation, an
oscillating bar, provided at its upper extremity with a closing plate or slide and
at the bottom with a counter-poise, is suspended below the coin slot. Said
counter-poise bears against a cam z integral with the shaft q and projecting in
the direction of the handle. It is obvious that, on turning the latter, the bar tends
to assume a perpendicular position, thereby closing the coin slot with its slide
plate, until the handle is turned back.
be
For the storage, within the case a, of the articles to be sold, tubes of any suitable
material and having a diameter dependent on the size of the latter, may
provided in the case a on either side of the shaft q.
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 :
1) An automatic sale apparatus, in which the delivery of the article, after dis-
engaging a shaft through a coin, is so effected by turning a handle rigidly
connected with the shaft, that a slide protrudes from the apparatus, drops the
article into a receptacle provided below the slide and, on returning the handle,
allows it to be removed, substantially as set forth.

page_text: 2) In the apparatus referred to in claim 1) the application of a locking and dis-
engaging device consisting of the rod m with bow fork and tooth o, which rod
is suspended by means of levers in hinges and so balanced by a
counter-poise n, as to cause the tooth o to be released from the notch p by the
weight of a certain coin and disengage the shaft q, substantially as set forth."
3) In the apparatus referred to in claim 1), the application of a delivery
mechanism consisting of the shaft 9 having a worm and handle, the nut u, the
bifurcated lever v movably connected with the latter, and the slide substantially
as and for the purpose set forth.
