Improvements in Coin-freed Mechanism for the Sale of Postage
Stamps, Tickets, and the like.
We, ALVIN SUSSMANN of Holzmarktstrasse, Berlin, in the German Empire,
Merchant and FRIEDRICH ZAHN, of Fehrbellinerstrasse, Spandau, in the German
Empire, Machinist, 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 :-
In the drawing
Fig. 1 is a side view partly in section of the coin freed mechanism or apparatus
of this invention.
Figs. 2 and 3 respectively a front elevation partly in section and a plan of the
delivery portion of the mechanism.
Figs. 4 and 5 are views of details.
The operation of the mechanism is effected substantially in the manner that after
dropping in a coin and then drawing out with the hand a slide, said coin impinges
against and actuates an angle lever which releases a clock work to set two friction
rollers in rotation and deliver out the article, a postage stamp for instance, carried
between them.
of
a is a plate upon which the entire mechanism is located. a curved coin passage
leading from the outside of plate a down to a coin receiver c (Figs. 1, 3,) which is
open at top and bottom and of a size corresponding to the coin to be used. This
receiver is fixed to one end of a draw or slide rod e, the other and outer end of
which is provided with a knob f by which the slide may be drawn out against the
resistance of a spring d. When this is done the coin is brought over the
aperture g in the bottom plate g, to fall into the case underneath. In this
outward movement of the slide the coin strikes against the bottom end
angle lever i turning on and holding arrested at the stud or pin ka spring wound
in the drum l. This latter has a toothed rim which is in connection through
teeth m with the roller m² and this latter through toothed wheel work m² and n with
the roller n'. Upon the spindle of roller m¹ is mounted a disc k' carrying the
aforesaid stud k. It will be obvious that when, owing to the coin striking the
end of angle lever i, the stud k is released, the rollers m', n', are set in rotation
by the spring located in the drum and that then the postage stamp, or the like,
held between the rollers will be delivered out at the slot z (Fig. 1). The periphery
of each friction roller is made to correspond to the length of one paper article to
be delivered so that to deliver only one postage stamp the rollers must be afterwards
again arrested. This is accomplished by the following means:--The slide e is
carried in a sleeve e¹ provided with a slot e² (shewn in dotted lines in Fig. 1)
through which projects the stud e³ fixed in said slide and in contact with the arm o
which is connected rectangularly and rigidly to the plates pl, p², respectively guided
on a screw p. The arm o is pressed by the spring q upon the stud e³. Plate phas
at right angles to it and at its upper end a projection r, which serves as a pawl for
the stud k. When, after dropping a coin into the machine the slide e is being
drawn out, the spring in drum t, owing to the action of lever i thereupon taking
place, is released and the entire mechanism set in motion the rollers then of course
rotating. With the drawing out of the slide e the stud e³ fixed in the same is
displaced along the slot e² of sleeve e¹ so as to permit plate p' acted upon by the
spring 9
to slide downwards until by its projecting part r, it arrests the stud when
the latter has performed oue revolution. The coin will then have passed the
point ¹ of lever i and this lever thus set free will return to its state of rest (Fig. 1)

page_text: in order that it may itself arrest the stud k when, in the return of the slide e by the
spring d, or by pushing the same back, the part is lifted out of engagement with
said stud. Upon another coin being dropped into the machine the same operation
may be performed over again. For the purpose of easily separating the paper
articles, at the upper end of plate p² (Figs. 4, 5) are provided two studs or pins
guided in a frame t arranged close to the delivery slot z in such a way that upon
the descent of plate p², that is to say, at the moment of the rotation of the rollers,
they are withdrawn out of said frame (Fig. 4) and allow the article to pass by, but
upon the return of the plate slide into perforations made between the articles which
may then be readily separated. u is a lever weighted upon its longer arm by a
weight and turning on u¹ by which the roller n' is kept pressed against the roller m¹.
w is a roller or pulley upon which the postage stamps or other paper articles are
wound. They are carried thence over w' to the delivery rollers m', n', and delivery
slot z as shewn in dotted line in Fig. 1. The turning point of lever i is located
upon the bracket y fixed to the bottom plate g to which also is fixed the spring y¹
which acts to bring lever i back to a state of rest.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A coin freed mechanism for the sale of postage stamps, tickets and the like,
in which two delivery rollers m', n', are driven by a coil spring and arrested by a
stud k through a lever i which upon the slide e being drawn out is released by the
contact of a coin dropped into the machine whereupon the delivery rollers are rotated
and the paper article between them slid out of the slot z, substantially as described
and shewn.
2. In the coin freed mechanism referred to, the part r as a pawl actuated from
the slide e to arrest the delivery rollers after each revolution and only releasing
them after they have been further arrested by the lever i, substantially as described
and shewn.
3. In the coin freed mechanism referred to, an arrangement for facilitating the
separation of the delivered article, in which two studs or pius s, upon the articles
being slid out of the machine by the operation of slide e, are drawn out of the frame
and upon the return of the slide e are slid into perforations between the articles,
substantially as described and shewn.
