PROVISIONAL SPECIFICATION.
Improvements in Coinfreed Machines for Delivering Sandwiches and
other Goods.
We, GUGLIELMо Borro, Mechanician, and CORNELIO TRABUCCHI, Merchant,
both of 38 An der Stadtbahn, Berlin, Germany, do hereby declare the nature of
this invention to be as follows:--
This invention relates to automatic delivery or sale apparatus which enables
persons to obtain a sandwich or a piece of buttered bread or similar object by the
insertion of a standard coin.
The apparatus acts under the influence of a propelling weight, and comprises in
its construction a cylindrical dish divided into compartments, each of which has
an equilibrated bottom flap. Said dish, which contains in its compartments the
articles offered for sale, is adapted to turn on its axis and to deposit after every
turn, one of the said articles on a suitably arranged plate.
The propelling weight serves to turn a driving gear, chiefly comprising a shaft
having at one end a ratchet and stop mechanism, and at the other end a pinion
which at every semi-revolution of the stop disc (forming part of the said stop
mechanism) causes the tooth wheel gearing in the said pinion to make a corres-
ponding turn, under the influence of a lever which on the insertion of a coin
places itself under the revolving fan or brakewheel of the clockwork.
The said propelling weight also serves to turn a disc which carries a suitable
number of upright posts serving as supports for pivoted plates loaded with
sandwiches. In the normal condition the said pivoted and equilibrated plates
slide over a rim of the cylindrical receptacle which in its front part has an opening
as wide as one of the said plates. Consequently, at this part, which is situated
opposite the delivery shoot, the said plate, together with the sandwich resting on
the same, is allowed to drop under the influence of its weight (the said plate,
together with the sandwich, being slightly heavier than the balance weight), so
that the sandwich will slide off, after which the plate will again rise to its hori-
zontal position under the influence of the balance weight, and is then secured in
position by a stop pin.
The supporting disc is provided, between the various sandwich plates, with
partitions which carry at the top and in front a small stop pin, against which rests
the empty sandwich plate, as mentioned above.
The latter remains in this position until a fresh coin is inserted in the slot, and
the mechanism begins to act again.

Improvements in Coinfreed Machines for Delivering Sandwiches and
other Goods.
We, GUGLIELMO BOTTO, Mechanician, and CORNELIO TRABUCCHI, Merchant,
both of 38 An der Stadtbahn, Berlin, Germany, 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 automatic delivery or sale apparatus which enables
persons to obtain a sandwich or a piece of buttered bread or similar object by the
insertion of a standard coin.
In the accompanying drawings Fig. 1 is a plan of a sandwich automaton
embodying our invention, and mounted on a pedestal of suitable height, so as to
be accessible even to children; Fig. 2 is a front elevation of the same, Fig. 3 an
axial section; Fig. 4 a bottom view of the disc I shown in Fig. 3; Fig. 5 a plan
of the base plate II shown in Fig. 3: Figs. 6 and 7 represent details on a large
scale; Figs. 8 and 9 show the propelling and stop-mechanism in section and side
elevation; and Figs. 10, 11, and 12 show details of the stop mechanism.
c is a
The mechanism proper is mounted on the top plate II of the stand III, to the
frout part of which there is secured a tray or dish shaped receptacle consisting of a
neat glass plate a, supported at 6 by means of a cross piece or bracket b.
shoot provided on the cylindrical case d which encloses the sandwiches, and
sloping downwards: along which shoot, whenever one of the carrying plates or
flaps e (presently to be described) descends, the sandwich thus lowered, slides down
from the plate to the above mentioned glass tray_a.
The cylindrical sandwich holder d, the lower edge d' of which is secured to the
top plate II and which is made of nickel or any other carefully polished material
of pleasing appearance, receives in its centre the pin f firmly implanted in the
said top plate II. Surrounding this pin at the bottom, there is a ring f', fitted on
an arm or bracket f, the end of which is turned up at right angles, and which
serves as a bearing for the shaft g extending from the propelling mechanism and
serving to turn the carrying plate or disc I which receives the sandwich-flaps.
The end of this operating shaft g extending through the bearing, carries a small
toothed wheel g', in gear with the larger toothed wheel h, which is rigidly secured
to the lower side of the above mentioned supporting disc or plate I. The number
of teeth of the gear wheels is such, as to maintain an exactly predetermined
ratio of speed to each other, and depends upon the number of sandwich flaps c
that are used. In the drawings, by way of example only, there are shown 16.
Assuming the toothed pinion g has 8 teeth and is to deliver a sandwich at every
half-revolution, as is supposed to be the case, where the arresting plate L (Figs. 9
10, 11 and 12) is arranged as described further below, then the large toothed wheel
will have to be provided with 8/2 x 16 = 64 teeth.
Upon the base plate II, which is adapted to turn on the pivot f, through the
medium of a sleeve located in its centre, 16 small standards are secured at proper
distances apart and provided with fork shaped arms or brackets h', 2, at thei
upper ends; the bent perforated ends of which forked arms serve as bearings for
a wire or rod i passing through them, with its ends bent upwardly, and answering
the purpose of a shaft. Upon these bent ends there are secured the sandwich

plates e are each divided into two parts of unequal length by a wall el situated

page_text: practically over the said small standards; the shorter rearward end being pro-
vided with a counterpoise weight e, not entirely counterbalancing the weight of
a sandwich. The longer front part of the said plate e lightly rests upon the
edge of the cylindrical receptacle, and is retained thereon and prevented
from upsetting. A second edge of the receptacle d, raised a little higher,
serves as a support for a heavy glass dome or globe k, covering over the whole
sandwich compartment.
A small metal cover or lid y, which conceals the tilting mechanism from view
and is mounted upon the pin f, is so arranged as not to interfere with the tilting
of the sandwich flaps.
Now in order to enable a sandwich to be delivered upon the insertion of a coin,
when the plate I turns together with the sandwich plates or in other words to
bring about the tilting of such plates e-the receptacle d has a slot cut in its
periphery, extending from top to bottom and corresponding in width to one
sandwich plate. Accordingly, at this point, facing the sloping channel c, the
receptacle is unprovided with a flange, i.c. the flange d' is here cut away, so as
not to interfere with the descent of the sandwich plate; and as the sandwich,
together with the front part of the plate, is somewhat heavier than the balancing
weight e, the plate must descend within the slot of the receptacle and cause the
sandwich to slide out of the machine; after effecting which delivery, it will
resume its horizontal position under the action of the counterpoise weight, and in
this horizontal position it will now be retained and secured by the stop pin m. Between
the several sandwich plates, partitions are erected upon the plate or disc I, each
partition being provided at its forward end with a small pin or stop m, under
which, as before stated, the plate which has just delivered its sandwich, comes to
take up its position.
The plate now remains in this position, until a fresh coin is inserted into the
slot, arranged in the well-known manner, when the mechanism will once more be
set in operation as before.
It now remains for us briefly to describe that part of the mechanism whereby
the pinion g' is caused to complete one half of a revolution. The driving shaft g
of this pinion corresponds with the arbour G of the goingwork (Fig. 8); through the
medium of a weighted chain resting in gear with the chain wheel H, this arbour
is set in motion as soon as the flyer K-which is normally held at rest by the
lever becomes released (Fig. 9). This release takes place instantaneously,
whenever a coin descending through the shoot, comes to impinge upon the lever Q
and somewhat shifts this lever to one side by its weight (see the dotted position in
Fig. 9). The lever arm J, under this action, advances in the direction of the
arrow and releases the flyer K; but in order to prevent the lever J from falling
back immediately after the coin has slipped off into the till, the nose or beak J
projecting from the upper lever arm J and which while at rest lies in the notch L
of the arresting plate L-has at the same time been disengaged from the said notchi
and has taken up its position upon the edge of the said arresting plate under the
action of a spring M (the shaft or spindle of the arresting plate coinciding with
that of the gear wheel g', or in other words with the shaft G).
The disc or plate L is loose upon the said shaft G, while the locking mechanism N
is rigidly connected with the said shaft. When, therefore, the lever arm J is
lifted out of the notch, the spring secured to the said mechanism N presses upon
the pin L2 fixed on the arresting plate or disc L, and throws such disc out of the
position in which it is shown in Fig. 12 into that represented in Fig. 10, where the
pin L stops in front of the arresting mechanism IV; whereupon, under the direct
action of the weight of the goingwork, the said shaft G begins to revolve. When
it has completed one half of a revolution, the second notch I3 of the arresting
plate L presents itself in front of the nose J of the upper lever arm J³, so that
such nose engages in the notch and arrests the mechanism. During these pro-
ceedings the sandwich plate has had time, as before stated, to complete one
sixteenth of a revolution."

page_text: Having now particularly described and ascertained the nature of our said In-
vention and in what manner the same is to be performed, we declare that what wo
claim is:
1. A coinfreed delivery machine for sandwiches and other goods, comprising
in its construction a shaft G and train of tooth-wheels adapted to turn under the
influence of a propelling weight, one end of the said shaft being provided with a
stop and locking device (L M N) and the other with a toothed pinion g', which
at every semi-revolution of the stop disc (L) produces a corresponding turn of the
tooth wheel h through the influence of a lever arm J adapted to pass underneath
the fan wheel K after the insertion of a coin, in combination with a disc I adapted
to turn under the influence of the said propelling weight and provided with
posts serving as pivotal supports for equilibrated sandwich flaps (e) which
normally slide over the edge of a sandwich holder or receptacle d, but tilt when
placed in line with the recessed part of the receptacle d and thereby allow the
sandwich or other article to slide through a shoot c down to a tray a situated near
the circumference of the said receptacle, substantially as described.
2. A coinfreed delivery machine for sandwiches and other goods constructed
and adapted to operate substantially as described with reference to the drawings.
