PROVISIONAL SPECIFICATION.
Improvements in Coin Freed Apparatus for the Automatic Sale
of Goods.
GEORGE MCDERMOTT 181 Long Lane Bermondsey London S.E. Engineer do
hereby declare the nature of this invention to be as follows:-
My invention has reference to improvements in apparatus of the kind known as
automatic coin freed machines by which articles or goods are delivered or can be
obtained upon or after the insertion of a suitable coin and my invention has for its
objects the removal of certain objections which obtain with existing apparatus of
this description and the production of a machine which is simple in construction
and which effectually prevents defrauding the public or allowing the public to
defraud it.
In carrying out my invention I employ a metal drawer or box with the back
end of same left open the drawer or box is 6 inch long 3 inch wide and about
1 inch deep with metal striking lever about 4 inches long which is fastened to
bottom of draw or box with 1 screw the lever is put into action by a flat steel spring
which is also fastened to bottom of draw or box with screw the bottom of draw
or box contains an aperture which acts as a regulator to any coin which the inventor
may intend to be used.
I also employ 1 slot plate which acts as the deliverer of the goods and also acts
as the resisting power until the necessary coin is inserted.
I also employ 2 flat steel springs which are fastened by 1 or 2 screws to slot
plate which form rejectors by taking baring on coin guide which is connected to
slot in plate My apparatus is connected to box containing goods by sliding into
aperture and made secure by thumb screw the top of the aperture of the goods box
forms a protection to money slot in plate.
In operation my invention works as followers upon the insertion of a coin of
suitable size and pulling slot plate the coin compels the lever to release slot plate
and expose goods in exchange for coin on the last article being drawn out a tongue
drops to keep the coin slot out of sight which prevents the machine from defrauding
the public.
Instead of employing flat springs in my apparatus I sometimes employ spiral
springs.
I sometimes employ a larger or smaller draw box lever and slot plate and
strengthening ribs according to the article I wish to be delivered.
It will be obvious that other arrangements of my improved apparatus may be
employed without departing from the essential features of my invention.

Improvements in Coin Freed Apparatus for the Automatic Sale
of Goods.
I, GEORGE MODERMOTT of 181 Long Lane Bermondsey London S.E
Mechanical Engineer do hereby declare the nature of this invention. and in
what manner; the same is to be performed, to be particularly, described and ascer-
tained in and by the following statement :—
My-invention, consists in the following improvements in coin freed apparatus:

page_text: Fig. A' in front elevation.
Figs. B & B show plan of delivery plate or drawer on upper and under sides
respectively.
Fig. B is the end elevation of plate or drawer and
Fig. B side elevation of the same.
Fig. C is plan of lever plate and C' is a section of C through the centre.
I will now proceed to describe my invention, reference being had to the said
drawings.
In its normal position, the apparatus is as shewn in Fig. A of the drawings.
The articles A are contained in a column the lowermost being received in a recess b
formed in the delivery plate or drawer B in which is a slot c of the right size to
admit the requisite coin; beneath the said slot c is a guide d. At the other end of
the drawer B is an opening formed with steps or notches e, for the purposes to be
hereinafter described. Beneath the said plate or drawer is a lever plate C, to
which is fixed a pivot f. upon which a lever g can work, the lever being kept in its
normal position by a spring h. One end i of the lever is formed with an incline
piece, the other end with a vertical pin or stop k. When the machine is not
being used this pin or stop k, remains in the space e' of the plate or drawer, so that
if the plate be pulled forward, the stop will engage with the first notch e, and
prevent its further movement.
When a coin of the requisite size is inserted in the money slot c it passes partially
through the guide d and a portion of its periphery rests upon the edge c of the
plate C so that it can come in contact with the inclined edge of the lever g when
the plate or drawer b is pulled forward, the coin acts upon the incline j, and moves
the lever into the position shewn by dotted lines the vertical pin or stop k is thus
moved out of the path of e so that the plate or drawer can be freely drawn forward
and the article A obtained. Upon returning the plate or drawer to its normal
position the springh forces the lever g back to its original position, so that the
vertical pin or stop k can engage with the notch e and prevent the plate or drawer
being again drawn out until another coin is inserted.
To prevent fraud by the insertion of lead or other substitutes for coin, of softer
metal than the proper coin, I employ two springs m m¹ which are attached to the
under side of the plate or drawer, the ends of which springs cross the money slot as
shewn in Fig. B³.
If a lead, cardboard or other such disc is inserted the ends of the said springs
are not driven outwards, but insert themselves into the periphery of the disc and
prevent its entrance. If however a genuine coin is inserted the hard metal of which
it is composed causes the springs to be forced outwards and the coin can then pass
to the guide d. The said guide piece is so constructed that if a metallic disc
which is not of the thickness of the proper coin is attempted to be used, it will if
too thick, not be received, and if too thin it will pass through the notch d¹ shewn
in the guide piece d shewn in Fig. B', this notch d¹ is at the side of the guide
opposite to the inclined end j of the lever g. The thin disc thus enters this notch
and falls through into the money receptacle n.
When the last of the articles A has been obtained, another coin cannot be inserted
in the machine so that the public cannot be defrauded by the machine. To effect
this I employ a lever or catch p, which when the machine is charged with articles,
rests upon the sides of the said articles, but when the last has been obtained it falls
down, and the projection 9 by coming in contact with the end g' of the opening
of the plate or drawer, prevents the latter from being fully returned to its normal
position. The money slot e remaining beneath the cover or guard plate r of the
machine.
To facilitate removal for repairs or cleaning I arrange the lever plate so that it
can be drawn out together with the slide plate or drawer. The said lever plate is

page_text: retained in its position by a thumb screw s upon unscrewing which the entire
mechanism can be removed.
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 improvements in coin freed apparatus for the automatic sale of goods
substantially as described.
