1, RICHARD SCHULZ of Tegel near Berlin, in the German Empire, Engineer, do
hereby declare the nature of this invention to be as follows :-
The mechanism forming the subject of the present application is especially adaptable
to that kind of automatic delivery machines in which the goods are directly delivered
from a case moving up and down or turning round an axis and provided with a series
of compartments, and it embraces the following features, a disc provided with ratchet
teeth or pins connected with a gearing operated by the movement of the case and a
pawl lever actuated by the introduction of the coin.
If the case is vertically movable it is provided with a series of inclined compartments
for the reception of the articles to be delivered and is guided by suitable vertical guide
rods.
This case is placed in an outer casing provided with a suitable delivery opening and
the compartments of the case will successively register with this opening during the
movement of the case and thus automatically deliver their contents. When a coin of
a predetermined size is introduced through the opening formed in the outer casing it
will slide down an inclined plane and drop down a channel onto a tray provided with
a guide rod which will disengage the pawl of a spur gearing one wheel of which gears
with a rack bar fixed to the case. The latter can now make a downward movement
until the next tooth or pin of the ratchet wheel connected with the above mentioned
gearing engages with the pawl which returns to its original position directly the coin
slides from the tray into the receptacle arranged underneath.
In this manner the case will ultimately occupy its lowest position and all the com-
partments will be emptied. In this position the opening for the introduction of the
coin may be covered by a slide actuated by the case, or the inclined plane down which
the coin slides may be lifted by means of a pivotted lever one arm of which is con-
nected with the inclined plane while to the other is fixed a downwards projecting rod
formed with a hook at the lower end which engages with a projecting nose on the case
when this arrives at its lowest position and is drawn down by this nose.
D
Any coin

page_text: introduced now will fall down a funnel-shaped channel instead of sliding down the
inclined plane and leave the machine by a suitable opening formed at the end of said
funnel shaped channel.
By filling only every other or every third compartment of the case the goods will
only be delivered after the introduction of two or three coins or the compartments may
be constructed of such a size that the bottom of the next compartment will not register
with the delivery opening of the apparatus until the case containing the compartments
has made the desired number of downward movements produced by the introduction
of the corresponding number of coins.
Whon the case is in its lowest position and all the compartments empty, it is raised
to its highest position by means of a crank handle placed on the square end of the
spindle of one of the gear wheels and the compartments may thon he filled again. To
record the number of compartments visibly from the outside of the apparatus a strip or
border may be attached to the case and the compartments marked thereon in running
numbers visible through a suitable oponing formed in the outer casing of the apparatus.
Coins of smaller than the required size drop through an opening formed in the
inclined slide direct into the funnel-shaped channel arranged underneath and pass out
of the apparatus through the aperture formed in the outer casing at the lower end of
this funnel.
The case containing the compartments may be made to move upwards instead of
downwards by the use of a suitable counterweight.
If the case containing the compartments is in form of a drum with radially
arranged compartments the above described wheel gear will engage with a spur gear
attached to the drum and the latter may be turned by means of a
the interior thereof or by means of a weight attached to a cord or chain running over
a roller.

I, RICHARD SCHULZ of Tegel near Berlin, in the Empire of Germany, Engineer, 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 mechanism forming the subject of the present application is especially adaptable
to that kind of automatic delivery machines in which the goods are delivered directly
from a case moving up and down or turning round an axis. This mechanism com-
prises a pawl-lever which is lowered by the weight of the coin introduced and unlocks
à disc which is connected with the case by an intermediate gearing so that the case is
enabled to make the necessary movement for the automatic delivery of the
article. The pawl-lever carries a dish or pocket and is balanced in such a manner
that it is lowered by the weight of the coin introduced. The coin introduced
drops from the dish or pocket as soon as the pawl-lever is lowered or in another
arrangement as soon as the gearing has unlocked a catch or jaw in the pocket of the
pawl-lever.
In the accompanying drawings:
Figs. 1 to 4 represent one form of the mechanism applied to a vertically movable
apparatus.
Figs. 5 to 8 represent the mechanism applied to an apparatus turning round
an axis.
Figs. 9 to 11 represent the mechanism on a larger scale.
Figs. 12 to 18 represent the second form of the mechanism with a weighing lever
and the locking jaw or catch on the pawl-lever.
The receptacle A Figs. 1-4 is provided with a series of inclined compartments for
the reception of the articles to be delivered and is guided by vertical guide
rods A¹ À².
This receptacle is surrounded by a case P and the different compartments of the
receptacle are brought successively in front of the delivery opening through which
the contents are delivered automatically.
To fill the receptacle A it is brought to its highest position, indicated in dotted lines
Fig. 3, and this is done by turning a small crank handle z placed on the spindle of the
disc (1.
By the introduction of a predetermined coin through the slot E Fig. 1, the mechanism
is unlocked and the receptacle A allowed to move. when the contents of one of its
compartments will be delivered automatically. The coin introduced glides down the
inclined plane E' and falls down the tube F onto a dish a to which is attached a rod X
Fig. 3, which disengages the pawl-lever B from the tooth wheel gearing . which gears
with a rack y on the receptacle A Fig. 2.
The receptacle A is then allowed to move downwards until the next tooth or pin of
the disc C comes in contact with the pawl-lever B which has returned to its normal
position as soon as the coin has passed from the dish a into the receptacle O arranged
underneath.
In this manner the receptacle A is gradually brought to its lowest position until the
whole of its compartments have been emptied. In the lowest position the receptacle
can either bring a slide in front of the delivery opening and close this or can lift
the inclined plane E' as indicated in dotted lines Fig. 3. For this purpose serves a
double armed lever s, Fig. 3, one arm of which is connected with the inclined plane E¹

page_text: by means of a small link while the other is attached to rod provided with a projection
or catch at its lower end against which strikes a projection & formed on the receptacle
when the latter arrives at its lowest position. When the inclined plane E¹ has been
lifted, any coin introduced through the slot E will fall in the funnel Q and pass out
again through the opening R Fig. 1.
This apparatus can easily be arranged to deliver the articles to be sold only after
payment of two or three coins, by simply placing the articles to be delivered only in
every second or third compartment of the receptacle A.
It is not necessary, that the size of the compartments are the same as that of the
delivery opening; the vertical movement of the receptacle may be arranged in such
a manner that the article contained in the next compartment is only delivered after
the receptacle has moved downwards twice or more times consequent on the introduction
of two or more coins, and the sum of these movements represents in this case the height
of one compartment.
The apparatus may if desired be arranged to make an upward movement for the
delivery of the articles instead of a downward movement, by using a suitable counter-
weight.
For differout sorts of coins, different slots are formed in the case (Fig. 1) the
smaller above the larger.
To show the number of the articles to bo delivered a bar P₁ may be fixed to the
receptacle, on which the running numbers of the compartment are marked (figs. 1
and 4).
Wrong coins do not reach the vertical channel F but fall through an opening in
the inclined plane E¹ into the funnel shaped channel Q and pass out of the apparatus
through the opening R.
Figs. 5-8 represents the mechanism adapted to an apparatus in the form of a
drum with radially arranged compartments which are emptied successively at a suitable
inclination.
The drum is turned round its axis by means of a tooth wheel gearing & as described
above, and a circular rack y. After the disengaging of the pawl-lever B the drum is
turned either by a spiral spring or by a weight attached to a cord or chain running
over a roller.
Figs. 9-11 represent the mechanism on a larger scale.
When the receptacle A is lifted it has the tendency by means of the rack y to turn
the pinion and with this the spur-wheel mounted on the same spindle and the
pinion gearing with the said wheel and the disc C mounted on the same spindle
with the pinion. This movement is prevented by a pin on the face of the disc C
bearing against a nose or projection of the pawl-lever B, (fig. 9).
When a coin however is introduced and falls down the channel Fonto the dish a
which is connected with the pawl-lever B by means of a rod ✗, the arm of the
lever B is lowered by the weight of the coin and the pin his disengaged from
the lever B, and the weight of the receptacle will turn the gearing. As soon as the
coin has passed off the dish a the lever B will return to its normal position and stop
the movement of the disc by the pin coming in contact with the nose of the suid
lever B. This operation is repeated after every introduction of the corresponding
coin.
h
In the mechanism represented in Figs. 12-18 the coin introduced is tested as
regards size by an arrangement provided on the lever B.
When the coin introduced through the slot E falls in the pocket a formed in the
pawl-lever B which locks the gearing a the disc C is set free and the gearing set in
motion until the lever B stops again the disc C by coming in contact with a pin of
the disc.
After the introduction the coin glides first onto the balance D fig. 15, which is
adjusted in such a manner, that only coins of a certain weight or very near a
certain weight can pass in the channel F, while lighter coins pass over the
opening of the said channel and heavier coins pass under the opening of the said
channel. The front side b of the channel F is adjustable so that the opening

page_text: of the channel can be adjusted according to the desired weight of the coin. The
movement of the balance D is limited by the pins c d.
The coin of the right weight passes into the channel F and falls in the pocket a of
the lever B in which it is tested as regards size. The jaw e pivoted at 1 Fig. 16,
forms one side of the pocket a and retains the coin as long as it is necessary. The
jawe can make a little movement between the pins 4 and 5 fastened on the lever B
but bears by its own weight in its normal position against the pin 4, while the cam f
pivotted in 2 bears by its own weight in its normal position on the pin 5 thus pre-
venting the jaw e moving (fig. 16). When however the arm g pivotted to the cam
f
in 3 is moved downwards, the said cam will be turned on its pivot 2 and the jaw e
will be enabled to make a small movement between the pins 4 and 5.
As stated before the coin introduced is held in the pocket a of the lever B which is
lowered by the weight of the coin and sets the pin h of the disc C free so that
the latter can now turn. The coin will be held in the pocket a until tha pin h
lowers the aring with the cam when the weight of the coin will move the jaw e
sideways and fall into a receptacle arranged underneath (fig. 17). The lever B
released from the weight of the coin will at once return into its original or normal
position, stop the pin and consequently the movement of the receptacle A which at
this moment delivers the article. The jaw e and cam f will also return to their normal
position ready for the next coin to be introduced.
This position of jaw e and cam f remains unaltered when the disc C is turned the
other way for lifting and filling the receptacle A, as the pivotted army is only lifted
every time the pin of the disc C passes it (fig. 18) and falls back directly into its
normal position (fig. 16). If desired the arm g may be made in one piece with the
cam and another arrangement made for lifting the receptacle A.
When the receptacle is in its lowest position, the balance D will be locked and
maintained in its highest position by the nose m of a rod bearing on the arm i of the
balance, the rod which is under the influence of a spring being drawn down by a
projection of the receptacle A engaging with a nose of the said rod. Any coin
introduced after such locking of the balance passes like the light coins over the
entrance of the channel and is again discharged from the apparatus.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In an automatic delivery machine a locking and unlocking mechanism comprising
a disc 'connected with a gearing a which is driven by the gravitation of the
receptacle A, the said disc being under the influence i.e. locked or unlocked by a pawl-
lever B which is lowered by the weight of a coin introduced in its dish or pocket a
for the purpose of allowing the receptacle to move for the automatic delivery of an
article.
2. The inclined plane E' which is lifted by means of a rod 7 operated by a nose k
on the receptable A when this has arrived in its lowest position, so that
any coin
introduced afterwards, and for which no article can be delivered, is discharged from
the apparatus by the funnel Qand the opening R.
3. The pocket a of the lever B, the jawe of which retains the coin to enable the
receptacle and the gearing a to move, this movement being stopped at the right
moment & the jaw e allowed to move by the movement of the cam f
4. The cam provided with a pivotted or rigid arm or latch 9 operated by the teeth
or pins h of the disc C for the purpose of disengaging the jaw e.
