page_text: Delivery of Goods in Exchange therefor.
We, FRIEDRICH SCHILLING, and JOHANN GEORG ADOLF BRÜNING, of the firm of
Schilling and Brüning of Bremen, in the Empire of 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:—
Our invention relates to apparatus for the receipt of coin and for the delivery of
goods in exchange therefor. Our said invention comprises means by which, each coin
when inserted in the said apparatus forms an intermediate link enabling the lowermost
of the articles piled one upon another, and which are intended for sale, to be drawn
forward; it being so arranged as not only to secure the precise adjustment of the
plates, which maintain the coin in position while the article purchased is being
removed; and the proper delivery of the coin to the cash-box after such removal;
but also to expose to view, at any time, the coin inserted in the last instance.
A device is moreover provided, which ensures the closing of the apparatus
immediately after the removal of the last article on sale.
The coin conduit, is fitted with a contrivance which enables base or counterfeit
coin, made of lighter material, to be removed; and finally in combination with such
contrivance, a device is arranged whereby not only the size, depth and weight of
each coin are tested, but all foreign articles, such as pieces of card-board, matches,
needles, base coin, and the like which may have been thrown in and obstruct the passage,
are removed by the insertion of the next genuine coin.
An apparatus constructed according to the present invention is represented in the
accompanying drawings, in which Figures 1, 2 and 3 are, respectively, a transverse
section, a plan view, and a sectional elevation of the apparatus.
Figure 1 is a detail side of the coin conduit A.
Figure 2* and 2* are plans.
Figures 3 and 4 are front views.
Figures 5 and 6 are sections on line xx_Figure 1* and Figures 7 and 8 are
arations an lino Ficuro 1* illustrating another groove or channel B fitted to the

page_text: +
Both these grooves or channels are surmounted by a guide c* Figures 5 to 8
resting upon inlet c¹ connected with groove A, and upon the support Ĕ provided at
the end of the channel B. The distance between the upper surface a* of the said
guide and the running edge of a genuine coin of the requisite size exactly equals the
diameter of such coin; whereas the side pieces 6* and 2 of such guide are of unequal
size, so that the shorter side piece c² extends downwards just sufficiently to cover and
maintain the upper edge of a coin of the proper size, while it allows any coin or piece
of a smaller diameter to fall through laterally.
e
The groove or channel A, as shewn in Figure 1* and 2* is formed by two
plates and f* hinged together at their ends by means of a bolt d*; one of which
plates e* is fastened to the inlet c', while the other, f*, has a tenon f1* attached to its
front end see Figures 2* and 4, which, passing through a hole g* bored in the side
wall of inlet c', projects into the opening of the latter, and is retained in position by
spring * The front edge of the bevelled tenon f*, at the same time, presses upon
the other side wall of inlet c, and keeping plates e* and * sufficiently apart to
prevent a genuine coin from falling through the space e¹* remaining open between
them. It follows, that each coin inserted into inlet c¹ will, through the medium of
tenon ₤1*, press asunder the plates e* and * and widen the space or slit e¹*, until it
enters groove A. Thus any foreign article which may possibly obstruct the groove A
is caused, by the coin itself, to fall through the enlarged slit e*, and is consequently
removed before the coin comes to pass the groove. Connected with plate f*, is a
double lever 2 and 3 Figure 1*, 2*, 5 and 6 mounted on shaft à resting in bearings i*,
the one arm 2 of which lever extends around plate f* and has its end bent as shown
in Figure 2* while the other is so arranged relatively to the plate c* that only a coin
of the proper size can roll down between the two. Thus the double lever, only
allows such coins to pass as have the required weight and the said lever is so
adjusted that a coin rolling against the end will act upon it with sufficient force to
push it out of the way. Cardboard dises however are not heavy enough to do this,
they are therefore retained or kept back by the lever 2. If now a fresh coin is
inserted in the slot C¹ the groove A will become widened by the plate e* turning on
its pivot d* as shown in Figure 2ª the said cardboard disc will therefore drop through
the groove A.
It has often happened that counterfeit pieces of coin being forcibly thrown into
similar apparatus have, in spite of all measures of precaution hitherto taken, succeeded
in actuating the mechanism; which fraud the said double lever is now adapted
effectually to prevent. For any piece, however forcibly thrust into the inlet will in
the first place touch the lever arm 2 and displace it to the right; but by the same
movement lever arm is forced into the way of the counterfeit piece, so that the
latter strikes against this lever arm, and, being thereby repelled, either falls through
the slit or is caught in the same. The double lever 22 23 is to prevent too rapid a
passage of even a genuine coin, beyond the end of groove A; for, as shewn in
Figure 6, the right coin must also, in the first place, strike the point of arm
which springs forward directly the arm 2 is forced back; when, in consequence of
the shock, it moves a little way back, before it can pass the point of the said arm 23³,
which in the meantime resumes its normal position.
23
The groove or channel B which is directly fitted to that of A, has a bottom k* at
its upper part, and from that point, down to its lower end, is provided with a slot 1*,
closed by a downward opening lid . This lid is hinged at 12 and is so poised by a
balance weight, that only coins of standard weight may press it down and fall
through so as to reach the mechanism of the apparatus proper; whereas any coin of
insufficient weight will pass onward without having any effect on the lid. To prevent,
however, standard coins thrown in great haste from accidentally passing the lid, the
end of the latter is fitted with a lever 13, which as soon as a good coin begins to lower
the lid, be it ever so slightly, takes up its position before the end of channel B. By
such means the onward motion of the right coin is checked long enough to allow of
its falling through lid P.
Between the channels A and B, another such lid may be interposed if desired; and

page_text: it may be so arranged as to cause too heavy counterfeit coins to fall through and thus
to divert them from the mechanism of the selling apparatus.
As may be seen on the right hand side of Figure 2 the bar g effecting the delivery
of each article purchased, is provided with a block g', situated directly under the
coin channel g (Figure 1) which receives the coins from the coin detecting device.
This block g carries four screws with conical points, three of which d, d, d², pass
through its walls while the fourth d³ rests in the arme of a lever connected with the
block by means of a hinge; the other arm e¹ of such lever being so actuated by
spring, that arm is pressed against the wall of block gl. In front of lever arm c
there is in the block g¹ a channel 1, opposite which is a pin h planted in the front bed-
plate of the apparatus. The conical points of screws à d', d², d³ are so adjusted that
the coin inserted through channel g is retained by the slightest possible pressure, so
that, the latter when moved onward by bar g and block g', carries the lowermost of
the articles piled up for sale along with it, and moves it a sufficient distance in the
direction of the buyer, for the pin h (which lies in the way of block gl and projects
into channel 1) to come in contact with lever arm e. As soon as this is the case
the lever arm e, together with screw d³, withdraws from the coin, so that the
latter, which the other screws can no longer retain, descends into conduit p leading
to the cash-box.
The arrangement of screws d, d', d² and d³ is of essential importance, as they
enable the opening for the reception of coins to be exactly adjusted to the required
size, any effects of wear notwithstanding. Or, instead of the four screws d, d', d², d³
one single screw may be employed for retaining the coins, in combination with
inclines, as shown to the left of Figure 2. Each coin is here maintained by the
angular notch i, screw and the movable hinge m terminating in an incline
and acted upon by a spring k; the proper adjustment of the coin receiving orifice is
in this case, effected by screw l¹. The disengagement of the coin is caused by
block being pulled forward, whereby the hinge m is pressed down from the front
wall of the apparatus.
As shown in Figure 1, a lever o, turning round a pin o¹, projects into the coin
passage, and carries a sliding lid pl designed to close the coin-channel p mentioned
above, being, itself, connected with such coiu-channel by a spring p². While a coin,
thrown in through channel g², moves onward, this lever o is turned round and slide
withdrawn from channel p, enabling the former coin to fall through into the cashbox.
But as soon as the coin has passed the lever o, the latter under the action of spring p²,
resumes its former position and again closes the channel p. Now, when the coin, after
being disengaged from its position between the four screws d, d¹, d², d³ by the action
of the pin h, descends into the channel p, it is retained by the slide p³, and there
remains visible through a glass p³, until another coin causes lever o to move forward,
as aforesaid, and thus to enable the coin which had just been exposed to view to drop
into the cash box.
In erecting the pile of the goods intended for sale, a plate a (Figure 1 and 3) is
placed upon the uppermost article, which is connected by a chain or similar contrivance
with the back end of a bent bar 6; to the other end c of which bar a helical spring b¹
imparts an ascending tendency, so that it extends a little way beyond the inlet
opening of the apparatus. The length of chain a¹ is so adjusted, that it is not
strained until it comes to rest upon the last article of the pile of goods on sale; when,
therefore, this last article is extracted the bar is forced downward by plate a and
caused to take up its position behind the inlet c', which is thus closed.
In the money channel 92 (figure 1 and 3) a spring n is provided, which is too weak
to retain a coin in its course, but has sufficient power to expel pieces of cardboard
or the like, through the lateral orifice g³, provided for the purpose in the coin inlet.
The money channel g² (Figure 1) is also fitted with a spring q, at its back-wall,
which projects into the coin-inlet in such a manner that a pin q'arranged on its inner
surface is forced through the back wall of the money inlet. When the apparatus is
at rest the block g¹ presses against the spring q, so that a coin inserted into the
money-inlet may enter the block g¹. Owing to the arrangement of spring q with

page_text: its pin, it therefore becomes possible, by once inserting a number of coins
simultaneously (even while block g¹ is on its forward move) to purchase an equal
number of articles, which however will be delivered in succession one at a time.
For while block g¹ is drawn forward together with the lowermost coin, which the
pin has allowed to pass, all the other coins, inserted at the same time, are retained
by spring g, through the medium of pin ', the said spring having in the meantime
resumed its position against the back wall of the coin channel. Then as soon as the
first or lowermost article of the pile is delivered, and block has moved back the
pin q is withdrawn from the next following coin by block g' which is pressed against
the spring, by the spring coiled round rod g so that this coin may now, in its turn,
enter the block g. After each return movement of the latter, however no more than
one coin can enter it, as, directly it is drawn forward, the pin 1 will press against
the lowermost of the remaining coins, and retain the same until the block g¹ moves
back again.
Thus as many articles are delivered to the buyer, in succession, as
there are coins simultaneously inserted into the money inlet. From the foregoing
it will moreover be understood that a standard coin may be safely thrown into the
apparatus, even while the latter is working.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First. In the apparatus as above described for the receipt of coin and for the delivery
of goods in exchange therefor. The arrangement of a block g' adapted to carry the
coin during its forward motion which block may either be provided with a channel!
and four screws d, d¹, d² and d³ three of which pass through the walls of the block,
while the fourth rests in a hinged spring lever e e' arranged behind the channel 1, or
have its coin receiving portion formed of an angular notch i a spring hinge lever m and
a screw in the former case a pin h is arranged opposite the channel 1, on the front
bed plate of the apparatus, for the purpose of releasing each coin after the delivery of
the article and allowing the said coin to fall into the cash box, and of enabling the
open space designed for the reception of the coins to be exactly adjusted to their
proper size, as above specified.
Second. A hinged lever o arranged within the money passage and provided with a
slide the front end of which extends into the channel which receives each coin after
the delivery of the article the said slide holding the coin in front of a window arranged
in the apparatus until released by the insertion of the next coin thereby rendering the
said coin visible; so that the last coin inserted is always exposed to view as above
described.
Third. The arrangement of a bar 6 somewhat above the money inlet: which bar is
connected with the plate a resting on the uppermost article of the pile by means of a
chain a which is only strained when the said plate a rests upon the last article left, the
said chain then acting upon the bar for the purpose of shutting the coin aperture and
preventing the insertion of coins in the apparatus, when its supply of goods is exhausted
as above described.
Fourth. The arrangement of a spring n in the money channel g² for the purpose of
expelling light or counterfeit pieces substantially as described.
q
Fifth. The arrangement of a spring acting upon the money channel by means of
a pin qand kept at a distance from the same by the block g₁ receiving the coin so
long as the apparatus remains at rest for the purpose of enabling a standard coin to
be safely inserted even while the block g¹ is being drawn forward or of enabling several
coins to be inserted at once and a corresponding number of the articles to be delivered
in succession substantially as specified.
.
Sixth. The arrangement of the two plates 1*f* connected by a joint; one of which
is permanently attached to the inlet c', while the other is movable, and, by means of a
tenon f* projects through a side-wall, into the inlet opening and retained in position
by a spring so that a slit el* corresponding to the depth of a standard coin is formed
between the plates e* and f* by the said tenon fi* bearing on the other side wall of

page_text: the inlet opening; for the purpose of removing any foreign article capable of
obstructing the passage by causing each time the slit to be temporarily widened by
the said coin itself as above specified.
Seventh. The arrangement of a hinged double-armed lever 12 ³, one arm 2 of which
projects into the coin passage from one side, and the other from the opposite side, but
not till after the former has touched the passing coin; for the purpose of pressing
laterally against both standard and counterfeit coins, and thus causing those coins or
pieces, which are not retained by the testing or guiding edge c² to drop, and be
subsequently expelled; while the standard coins which are prevented from falling by
the said guide c, are allowed, when resuming their forward motion, to roll past the
lever (3) which by that time has resumed its normal position substantially as above
described.
Eighth. The arrangement of a slit 1* in combination with a lid l which is so poised
that any coin of standard weight may press it down, while lighter pieces pass over it
without effect the lever 13 being provided which, whenever the said lid is thus pressed
down, takes up its position in the money passage, for the purpose of ensuring the
descent of standard coins through the open lid, substantially as described.
