Improvements in Coin-freed Sale Apparatus.
I, GEORG ADOLF SINSEL, of Leipzig, in the Empire of Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The object of this invention is an automatic sale apparatus for articles of every kind
which is operated by one or several coins and essentially constructed as follows;
In a suitable case a chain mechanism is provided for the sale of flat articles which
consists of two superposed drums and a surrounding endless chain, the single links of
which serve as holders for the objects to be sold and to this end consist of a wire so
bent that its two more or less parallel free shanks are adapted to embrace the article
while the inner part forms a hook for connecting the contiguous links. This chain is
capable of periodical movement by means of the lower of said drums, which is
actuated through a special device hereafter described. The delivering mechanism
operated by the coin or coins is constructed as follows:
The coin passage terminates above a coin-receiving plate adapted to oscillate
between the fork of a bifurcated two-armed lever and to occupy by aid of a spring
a parallel position therewith when allowed a free movement.
To allow the prepon-
derance of said lever over the plate when struck by the coin, to be regulated according
to requirement, the pivot of the plate carries outward on one side of the fork a rigidly
secured lever with displaceable poise. The non-bifurcated end of the two-armed lever
carries a
pivot adapted to catch into a corresponding slot of a revolvably lodged
releasing fork capable of sliding on an upwardly extending partly inclined rim of a
rod operated from outside and of occupying, prior to the dropping in of a correct
coin, such a position as to bear with its free end on said rod close to the inclined
extremity of its rim, thereby preventing a movement of the rod. On introducing
a correct coin, the main lever descends on its bifurcated side to an extent deter-
mined by a peg on which the weighted lever abuts; thereby the other arm' of
the two-armed lever rises and by aid of its pivot enables the releasing fork to
engage with the rim of the rod and the latter to be pulled out.
At its fore end the rod is connected to a fork-shaped slide or drawer provided
with a suitable number of upward rims which catch behind one of the cards or
other flat articles lying on the chain and produce this article when the rod
is pulled out.
By the outward movement of the rod the releasing fork rises on the rim thereof,
thereby giving the bifurcated lever an inclined position. At the same time the
weighted lever, prevented by the peg referred to from oscillating with the latter
causes the coin-bearing plate to receive an oscillation exceeding that produced by the
coin and sufficient to deliver the latter into the coin receptacle.
The drawing rod and slide when released resume their normal position by the
action of a suitably placed helical spring. On its bottom side the rod is provided
with a convenient number of teeth or sprockets gearing with a corresponding
wheel which by means of a suitable click attached thereto causes, in the last
period of the return of the rod the lower chain drum, through a toothed wheel con-
nected therewith, to be so far revolved that the following link of the chain is placed
close above the returned slide or drawer.
In order to admit of the release of the slide by means of several coins representing
together the amount fixed for the purchase of the article, several coin passages are
provided side by side each of which terminates above the coin receiving plate, which
is adapted to be easily exchanged and can be correctly regulated by means of the
poised lever mentioned above to the weight of the coin or coins fixed for the purchase
of the articles

page_text: The improved apparatus may also be employed for the delivery of thicker articles
or packets which are placed upon each other in a receptacle provided near the
fore end of the rod. In this case the delivery chain is not operated. The slide
or drawer has the shape of a bent or kneed plate and, when it is drawn out, the next
packet or article rests on its upper or rear portion until, after the return of the slide,
it can fall into the cavity.

Improvements in Coin-freed Sale Apparatus.
I, GEORG ADOLF SINSEL, of Leipzig, 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 coin-freed sale machines and has for its purpose to provide
an apparatus of this class which is adapted for the sale of articles of every description
that can be reasonably delivered in this way, it being workable at the same time by
means of several coins of different value.
The principal object of the invention is the peculiar disposition of a mechanical sale
apparatus, by which a device, serving to hold cards, pictures or other objects, is
actuated by the introduction of a coin or several coins and allows the purchased
article to be taken from the apparatus.
Reference being had to the accompanying drawings, Sheets I to IV, in which like
letters refer to like or analogous parts.

The improved sale apparatus is constructed and works as follows:-
The main casing contains a chain mechanism consisting of the chain drums A

page_text: and B and the peculiarly shaped chain D. The single links of the latter serve as
holders for the cards or other flat articles to be delivered by the apparatus and are
for this purpose given the shape indicated by Figs. 7 to 9. Said links are adapted to
be easily joined to an endless chain or band and have bends a destined to hold tho
flat objects to be sold. The chain D, which is made narrower than the said objects.
receives periodical movement by aid of the drum A actuated by means of a separate
gearing.
The mechanism, which is operated by the introduction of the proper coin, to
allow of the removal of the purchased article is disposed in the apparatus as
follows:
The coin passage G terminates above a coin receiving plate 6 adapted to oscillato
about on the two-armed lever E between the bifurcated extremities E' thereof and
to be placed, when allowed free movement, into the same direction with this arm El
of the lever E by means of the spring f. Moreover the fulcrum d of plate bis
rigidly connected on the outer side of E or E' with a lever g, which carries an
adjustable poise F for the purpose of allowing of an adjustment of the preponderance
of E corresponding to the coin descending on b. The arm h of said lever E, carries
a pivot which serves to place the releasing piece H, revoluble about K in con-
nection with E by engaging with a slot 7 provided in piece H. The latter is
bifurcated to enable it to ride on the ridge of the slide rod K, Figs. 5, 12 and 14,
and to assume, prior to the introduction of a proper coin. the position shown in
Figs. 1. 4, 6, 10 and 13. It is obvious that in this position a movement of the slide
rod K, carrying the ridge i, is obviated, the piece H establishing an abutment
against . When however a corresponding coin is dropped on the lever E. i.c. on
lever, the lever E inclines at E¹ as far as permitted by the peg n, supporting the
lever .
The pivot rises, thereby raising the piece I sufficiently to allow it to
ascend on the ridge and the rod K to be drawn out. The latter is connected at
its front end. that is to say, near the knob K' Iving outside the casing of the
apparatus, with the fork-shaped drawing slide L, the upwardly projecting rims or
bends m of which are adapted to catch behind the cards or other flat objects.
contained in and to be taken from the chain and cause one of said articles to be shifted
out, when the rod is moved forward.
The apparatus comes in operation as follows:-
A. proper coin, on being introduced at G arrives on the coin receiver b, causing
the same to oscillate with E. as also, by aid of pivot e, the releasing piece H
situated in front of the ridge 2.
The slide rod K being now freed can be pulled out whereby the fork slide L'
takes a picture or similar article from the chain D and carries it at o to the
outside. During this process the releasing piece slides upward on the ridge i
thereby causing the lever E to assume the inclined position shown in Fig. 5. while
the coin receiver is given a further downward swing for throwing off the coin
by the poise lever being prevented by the peg n from oscillating with E and con-
sequently causing b to further descend, as, illustrated in Figs. 5, 12 and 14. On the
release of the drawing rod K, the spring M. causes the slide L, rod K, and with the
latter the ridge i. to so far recede as to allow the releasing piece H to resume its
former position before the abutment of the ridge thereby preventing the rod from
being pulled out, until a fresh coin of proper value is introduced into the apparatus.
Simultaneously with the return movement of rod K the chain D is re-adjusted.
The rod K carrying the delivery slide L is provided with teeth gearing into the
wheel N which has, attached thereto, a click P. Fig. 1. rigid at one end and acted
upon by the spring s. While the rod K is being pulled out, the toothed wheel N
revolves, whereas the click P slides ineffectively over the teeth of the drum wheel R.
On the return of the slide L however, that is to say, during the latter period of move-
ment thereof, the click P of wheel N engages with one tooth of wheel R.thereby causing
the chain drum A. to revolve by one division. Thus the next chain link carrying, a
card or article C arrives immediately above the introduced slide L. Figs. 1 and 2.
In order to fit the apparatus also for requiring several coins to be introduced for

page_text: releasing the slide L, several coin slots or passages G₁ may be provided side by side,
all of which terminate above the coin receiving plate &, Figs. 10 to 12.
The said plate ', which like b, is so shaped as to constitute an easily exchangeable
intermediate piece, is adapted to be precisely adjusted to Ei.e.to E by means of thedis-
placeable regulating poise E on lever g₁ to determine the gravitating effect required
to produce oscillation. It can therefore be arranged that, for instance, only on the
introduction of a third coin of certain value or weight the lever E is caused to swing
i.e. the piece I to be released for operating the mechanism.
The improved apparatus may also be employed for the sale of cakes or packets,
Figs. 13 to 16, which are heaped up in a channel T; the chain D may in this case be
dispensed with, the slide L being formed as a kneed or bent plate S, Fig. 14, whereby
the lowermost packet is always held up until it is allowed to fall att into the returned
slide. Fig. 15.
The shape of the whole apparatus can be suited to the kind and shape of the articles
to be sold.
The improvements represented by Figs. 17 to 24 constitute some material supple-
ments to the apparatus, illustrated by Figs. 1 to 16, which are also applicable to
other apparatus. This supplementary matter consists in the combination of a safety
coin supply device with the coin lever releasing mechanism and in the application of
a device for the mechanical sale of liquids, the quantity of which may be determined
by adjustment.
The operation of this device which is actuated by the slide described with reference
to Figs. 1 to 16, is as follows:-
The safety coin supply attachment A, which is independently described in my
complete specification No. 1645 dated January 30th 1890 is secured to the outside of
the apparatus and placed in the following manner in separately operating connection.
with the releasing mechanism.
The coin carrier B is provided with a peg d', which, in the lowest position
of B1, .e. when the coin is allowed to enter the coin passage, is held by a hook
lever U. The latter serves to keep the passage G₁ closed by holding down the coin
carrier B, until the slide K of the apparatus is drawn and a sold article delivered,
For, as soon as the slide K. is drawn forth, the releasing rib projection thereof
(Fig. 17 position indicated by dotted lines) abuts against the lower extremity of
lever U causing the latter to be moved contrary to the pressure of the spring and
to free the coin holder B drawn upwards by the action of spring. f whereupon a
fresh coin can be dropped in.
To allow coins or objects of insufficient weight, for instance paste board plates to be
removed from or thrown off the coin lever El and the mechanism, when rendered
inoperative by such interferences, to be readjusted for action, without the main slide K
becoming thereby movable for taking out objects of sale, the following peculiarly
operating mechanism is provided :-
Below the coin throwing lever E which carries the pin e known from the description
and drawings, is situated a lever V movable on the fulcrum u and carrying a pin w,
by whose engaging with the slot r of the lever W revoluble about point y, this lever
is moved up and down corresponding to the movement of lever V, and, when elevated,
enters with the surface, provided laterally at its free extremity, into the recess m¹ at
at the slide K. The lower arm VI of the two-armed lever V is connected with a
drawing rod Z movable from outside by the knob Z and drawn to the inside by
means of spring force or in an equivalent manner. Said rod Z carries a pin o¹ which,
on its being pulled out, acts on the lower fork-like bent extremity of n of the coin
carrier disengaging lever U. Consequently, when the apparatus is inoperative and
the lever Z therefore required to be drawn, first the lever V so raises the lever W by
means of pin was to cause the surface to engage in m³, thereby fixing the slide K.
Subsequently the lever V. on being turned further, tilts the coin holder lever E as if
throwing off the coin, and thereby clears the mechanism without allowing the slide K,
being locked by the surface z, to be drawn out. At the same time the pin o¹ has
disengaged the coin introducing lever Un¹ and on the return movement of and V

page_text: the surface recedes from the recess m³, the apparatus being thereby restored to
operativeness.
For the purpose of allowing the improved apparatus, but chiefly the releasing
mechanism hereafter referred to in claims 1 to 3, to be employed for the delivery of
liquids, the following contrivance is provided;-
The apparatus contains a peculiarly fitted measuring cylinder M, through which the
quantity of liquid to be discharged each time is taken from the reservoir R', Fig. 22,
and precisely measured. For this purpose, the cylinder M¹ contains a piston N¹
attached to an adjustable rod s adapted to be fixed by means of a screw. Said
piston has a valve P Fig. 24, which carries a downwardly extending closing pin t¹
by means of which a closing position is attained by aid of a float S¹ as soon as a pre-
determined quantity of liquid has entered through the three-way cock J.
This is effected as follows:-
By the entrance of said quantity of liquid into the measuring tube, whereby the
float S and through the latter valve 1" is raised by pin t¹, the escape of the
remainder of air contained between piston N¹ and float S, and consequently any
additional supply of liquid is prevented. The three-way cock J is connected by
means of a lever 0 to the main slide K of the sale apparatus and therefore given
different positions according to the movement of the slides. When the latter is closed
the cock occupies the position shown in Fig. 24, the communication between the
reservoir R and cylinder M being then established, while on the slide being drawn
out, it is placed in the position, indicated in Fig. 22, in which the liquid is discharged
through the pipe from the cylinder or measuring tube M' and delivered to the
purchaser.
The last described contrivances are only applicable in combination with the
mechanisms explained with reference to the drawings at the beginning of the speci-
fication, and the apparatus constituted by said mechanisms is not only rendered more
precise and reliable in action, but also its applicability is considerably supported and
diversified by the application of the supplemental appliances referred to.
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) In a self-acting apparatus for the prepaid delivery of pictures, tickets or other
flat articles, the combination with an endless chain D, which consists of detachable
holder links provided with bends and is adapted to be moved, after each delivery,
by one link on its drum A, of a coin receiving lever bg, spring f. lever E with pin e,
releasing piece H, peg n, slide rod K with ridge and teeth r, spring M. toothed
wheel N with click P, wheel R, the whole combined and operating substantially as
and for the purpose set forth.
2) In the apparatus forming the subject of claim 1), the application, as a sub-
stitute for the endless chain 1) referred to, of a channel T in combination with a
slide Shaving a bent or kneed bottom plate, for the purpose of allowing the apparatus
to be employed for the sale of-in lieu of flat articles, cakes, packets or similar more
voluminous objects, substantially as illustrated and described.
3) In the coil-freed sale apparatus forming the subject of claims 1 and 2, the
combination with the constituent mechanism thereof, of a safety coin supply attach-
ment A', claimed with the application for Letters Patent No. 1645 dated January 30th
1890, the co-operation of said mechanism and attachment being so effected that by
the action of ridge on the lever U, the coin receiver 13 is returned to its
receiving position, and the lever E caused by the lever V, which is actuated by
drawing rod Z, to perform the equivalent of a coin-throwing movement, the pin in
having previously made the surface z of lever W to lock the slide K, and at the same
time the coin supply device B to be likewise returned to its receiving position by the
action of rod Z on the arm n' of lever U, substantially as and for the purpose set forth.
4) In the apparatus forming the subject of claims 1 to 3, the combination, as a
supplement thereto, for the sale of liquids, in lieu of the appliances referred to for the

page_text: delivery of other articles, with the slide K, of an arm 0, three-way cock J, measuring
tube M, piston N₁, float S1, valve P with pin, reservoir R¹ and delivery pipe 11,
arranged and operating in the manner substantially as illustrated and described.
Dated this 31st day of January 1890.
