PROVISIONAL SPECIFICATION.
Improvements in Coin Freed Machines.
JAMES GILBERT CUMMING 88 Polwarth Gardens, Edinburgh, Mechanical and
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
--
This invention has for its object an improved apparatus by which after a suitable
determined coin has been first inserted in an opening provided for the purpose, the
mechanism aftermentioned is enabled to be unlocked or released. The apparatus
works in combination with the mechanism contained in a coin freed machine, whilst
after each operation and the whole apparatus has been returned to its original
position, it is ready to be again operated, after another coin has been inserted.
When a coin has been inserted in the opening provided, it rolls or falls down an
inclined shute, which guides it in between two levers.
These levers are pivotted, and work in combination with a bolt, drawer, or other
suitable mechanical arrangement.
The bolt, drawer or other suitable mechanical arrangement, is provided with a
cam, recess, and toothed rack and extends through an opening in the machine.
The apparatus may be constructed with or without a mechanical arrangement
for preventing the bolt, drawer or other suitable mechanical arrangement,
being returned to its original position until the apparatus has been properly
operated.
Dated this 3rd day of July 1890.

Improvements in Coin Freed Machines.
I, JAMES GILBERT CUMMING, of 88 Polwarth Gardens, North Merchiston,
Edinburgh, in the County of Midlothian, North Britain, Electrical 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:-
My invention has for its object an improved apparatus which after a suitable
determined coin has been first inserted in an opening provided for the purpose, the
mechanism is enabled to be unlocked or released. The apparatus works in com-
bination with the mechanism contained in a coin freed machine whilst after each
operation and the whole apparatus has been returned to its original position it is
ready to be again operated after another coin has been inserted.
When a coin has been inserted in the opening provided it rolls or falls down an
inclined shoot which guides it between two levers. These levers are pivoted and
work in combination with a bolt, drawer, or other suitable mechanical arrangement.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended an explanatory sheet of drawings, in the several
figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a vertical section taken through the middle of the box containing
the cards or other articles, and the mechanism for delivering the article.
Figure 2 is a plan showing the mechanism.
. The cards or other articles for sale are shown at a, a in the box, (Figure 1.)
They are partly supported on a grooved wooden bottom of the box, and partly

page_text: on a piece of met al d³, which is connected by means of the piece d* to, and moves
with, the slide or bolt D. On the metal d³ a projection d is formed, which when
the handled of the slide or bolt D is pulled out, catches the bottom card and
pushes it through the slit e in the box. In order to prevent any thing being pushed
into the box through the slit in front, through which the card is pushed as aforesaid, 5
a springy piece of metal fattached at one end f¹ to the bottom of the box, and
turned up at the other end so as to cover the slit, is provided. The card as it
comes out pushes the springy piece of metal away from the slit, and when the
card is removed the metal springs back and covers the slit again.
pressure to
The mechanism for actuating the machine will be understood by reference to 1
Figure 2. The coin is put into a slit provided in the front of the box and falls
through a shoot on to the jaws 9 and h of the lever or pawl G and lever H, where
it is held, and forms a solid connection between the jaws, as shown at Figure 3.
The lever or pawl G is pivoted at g', and the end 92 is pressed against the slide or
bolt D by the spring s¹. The other lever H is pivoted at h', and has a pin h²
attached to it, which is pressed into a hollow formed in the slide or bolt D by
the springs. When there is no coin connecting 9 and the handle d can only
be pulled out until the toothed rack or projection d' comes in contact with the
end of the lever or pawl G. This motion is sufficient to take the pin ² out
of the hollow in the slide and turn the jaw h a little nearer the jaw g, but is
not enough to bring the projection de on the metal piece up to the card.
When, however, the coin is dropped down the shoot and is caught between the
and h. If now the handle d
jaws g and h, a solid connection is formed between
is pulled out, as the pin 2 comes out of the hollow in the slide the lever H is
partly turned on its pivot : The motion of h transmits through the coin a
and the lever or pawl G turns partly round the pivot g¹. Thus the
end 2 lifts and clears the toothed rack or projection d', and the handle d is free
and can be pulled out, carrying the slide and metal piece d³ with it. The pro-
jection de pushes the lowest card through the slit. The slide or bolt D is recessed
or cut away as shown in dotted lines at d². When this part is brought along to
the pin h² the pin is forced into the recess or hollow, and the jaw h separates from
the jaw g and allows the coin to fall down into a receptacle provided for the
purpose. The pawl I having a spring s³ pressing it against the slide or bolt, is
provided to prevent the slide going back before the card has been delivered through
the slot e. The notch d³ comes up to the end of the pawl just before the coin is
released from the jaws, and thus the slide is prevented returning until it has been
pulled out to the full extent. In order to prevent the pawl I catching in the
notch d³ when the slide is returning to its normal position after having delivered the
card, a metal piece J is pivoted at j. The end of this piece is drawn along by
the end piece d of the slide or bolt and lifts the end of the pawl I from the slide
or bolt. After the notch has passed the pawl in the return of the slide, the end ¹
of the piece J is knocked away from the pawl by the end of the slide or bolt
striking the arm 2 which is attached to J. As the slide is pulled out it compresses
the spiral spring S, and after the card has been delivered the spring forces the slide
back to its normal position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The mechanism herein described for locking a slide or bolt and releasing it by
means of a coin so that a card or other article may be delivered, substantially as
described.
