COMPLETE SPECIFICATION.
Improved Coin-freed Apparatus.
I, GRAYDON POORE, of 35 Oakhill Road, Putney, in the County of Surrey,
Civil 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 relates to an improved construction of coin-freed apparatus
applicable to so-called automatic delivery machines and other purposes, and has
for its objects to attain increased simplicity strength, efficiency and non-liability to
derangement.
I will fully describe my invention in reference to the accompanying drawings,
in which
Fig. 1 is a left side and Fig. 2 a front elevation, the casing being removed.
Fig. 3 is a right side elevation and Fig. 4 a plan of the sliding carriage with
table removed.
Fig. 5 is a plan of the locking tumbler.
Similar letters refer to similar parts in all the figures.
The sliding carriage A is a casting of suitable metal of the form shown in
Figures 1 and 3. The rear part of the upper surface is raised as shown and to it
is fixed a table B in such manner that a space s intervenes between the top of A
and the base of table B to admit of the passage of frame. F when the table is
drawn out, for which purpose a handle is provided. The table B may be of any
shape adapted to the goods to be sold and is illustrated for example with a well w
adapted to come beneath and receive the lowermost article of a column of
articles W, stored above it in a suitable casing in the known manner. The
forward end of A has a flange A¹ in which is cut the money slot S and a spring &
may be applied to either side as shown in Fig. 4, between which the coin is to be
pressed down. On one side of A, a ledge a, Figs. 3 and 4, is formed for a purpose
hereinafter set forth. A suitable slot is formed in the frame F for the coin,
which, when the table and carriage are in normal position coincides with the said
money slot S.
The forward part of the lower limb A2 of A is formed with a series of
steps a, a, and the rear part is left plain. The carriage is mounted on a pair of
guide bars T T passing through lugs a' formed or fixed upon the carriage A and
through the flange A', at either side. The guide bars T T, are supported at the
back by standards and at the front by the part of the bracket C, both parts
being fixed to the bed plate P.
In bracket C is centred at the locking tumbler L, which is constructed as
shown in Figs. 1, 2, and 5 with a catch 1, at its rear end and a face at its front
end adapted to engage the steps a². On one side is an upward projection P,
carrying a pin, projecting inwardly for a purpose hereinafter set forth.
The operation of the apparatus is as follows:-On insertion of a coin at S and
to the position shewn at r, its lower edge engages cutch ; on drawing out table B
by handle b, the coin at once turns the locking tumbler L on its centre c, and it
thus clears the first step a' and the carriage is freed, the pin being then raised
just above ledge a. On further withdrawal the coin passes over the catch and
falls to the base Z, which is provided with a locked drawer, and at the same time
the pin falls on ledge a, holding up the tumbler L and preventing its engagement
with any step a until the drawer is sufficiently withdrawn; then the pin clears
ledge a and allows tumbler L to fall and it will ride over the plain part of A*
On completion of the purchase the table B is returned, the tumbler L dropping

page_text: step by step and preventing the withdrawal of the table again until another coin
has been inserted and the operation repeated as described.
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 :-
A coin freed apparatus constructed and arranged substantially as and for the
purpose hereinabove described and illustrated in the drawings.
Dated the 4th day of August 1892.
