Improvements in Coinfreed Delivery Mechanism for Goods Vending
Apparatus.
We, GEORGE HAYDON and HAYDON & ÚRRY, LIMITED, all of 353, Upper
Street, Islington, in the County of London, Mechanical Engineers, 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:
Our invention relates to coinfreed delivery mechanism for use in boxes or
apparatus for the storage and sale of goods or articles of any desired kind. The
object of our improvements is to ensure the retention of the coin in the receiver
during the full outstroke of the delivery drawer and the discharge of same occurs
during the instroke, so that it is impossible for the operator to lose his coin
before receiving the goods, and also to prevent robbery of the goods, and to provide
a simple, efficient and reliable apparatus.
We will describe our invention fully in reference to the accompanying drawings
in which Fig. 1 is a sectional elevation showing the drawer partly pulled out
to admit the coin. Fig. 2 the same showing the position taken and maintained
by the coin during the full outstroke of the drawer. Fig. 3 the same, showing
liberation of coin at the commencement of the instroke of the drawer. Fig. 4
is an inverted plan of the drawer and its locking mechanism. Fig. 5 a plan of
the drawer. Fig. 6 an inverted plan of the drawer showing underlying rack
and cams hereafter referred to.
Similar letters refer to similar parts in all of the figures.
A is a fixed vertical container of shape and dimensions to accomodate any
kind of goods to be sold. It is mounted upon a frame B in which slides the
goods delivering drawer 1). The frame B is of suitable form such as is shown
and has a slot 6 through which the coin passes. 1 is a downward projection to
which is pivotted the locking lever E having a downward projection with lip e
at its front end, and rack teeth e e¹ on its lower side at the rear end. The
lever E is normally pressed down by spring e to the position shown in Fig. 1.
The
The drawer slides in side guides in the frame B, and has a transverse money
slot d coinciding with slot above referred to so as to admit the coin ..
drawer has an incline at D and certain serrations d¹ on its top side and an
upstanding lip at its back end for drawing forward the lowermost of the
goods superposed in the container A. Over the drawer is a drop and guard
plate a pivotted to the container A as shown and normally pressed down upon the
surface of the drawer by a spring a¹; the face of this guard plate is obliquely
disposed at a for purposes hereinafter explained. A bridge piece from frame B
fits closely around the drawer, preventing tampering therewith, and serving as
a guide.
The lower side of the drawer is formed with a fish-tail cam t Fig. 6 a short
rack and a bifurcated fixed projection with a cross pin 13 at its rear end.

page_text: Such being the construction, the action is as follows.
The parts being in the position of Fig. 1 the drawer cannot be pulled out
since on attempting to do so the cross pin 3 of the projection engages and
is stopped by the back end of the locking lever E. When the coin is inserted it
is retained by the lever lip e in the position shown in Fig. 2 and on commencing
to pull, out the drawer the two inner edges of the fish-tail cam t engage the
upper part of the coin and force it downwardly, thereby depressing that end of
lever and removing its other end out of the line of travel of the pin in the
part of the drawer, as shown in Fig. 2. The drawer can then be pulled out
fully carrying with it the lowermost only of the goods which only is engaged by
the back lip; in coming forward the article lifts and passes under the guard
plate a, which falls after the article has passed. The coin all the while has been
maintained in the position of Fig. 2 but during the reclosing the underlying rack
teeth engage the upper part of the periphery of the coin and reverses its
direction of inclination so that it then slips off the lip e and falls to a receiver
guided if necessary by a plate such as : When the drawer is fully reclosed
all the parts resume initial position, any tampering by reciprocating the drawer
being prevented by the engaging of the lock-lever rack-teeth e¹ e¹ with the cross
pin of the bifurcated projection of the drawer. Thus it will be seen that
the action is truly mechanically positive, and therefore reliable, the customer
cannot lose his coin without return in goods. The fixed bridge piece 2 of the
frame B prevents access to the drawer even should the wood or the casing become
shrunk or warped. The combined effect of the surface serrations and the
guard plate a prevent the possibility of the insertion of a knife or pin point
into the container and the whole arrangement is simple, durable and efficient.
The drawings show an apparatus designed to take Hat cards only in the receiver,
but for other goods or packets. obviously the drawer and the guard plate a and
other parts are appropriately formed.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
.we claim is: :-
1. In a coinfreed delivery mechanism for goods vending apparatus, the means
by which the coin is retained during the full outstroke and released during the
instroke of the sliding drawer, consisting in the spring return locking lever E
pivotted beneath the frame and having a coin lip e and rack teeth el in connection
with the cam t, rack t¹ and arm 2 formed on the under side of the sliding
drawer, all arranged and adapted to operate substantially in the manner described
and illustrated in the drawings.
2. In a coin-freed delivery mechanism such as above referred to the means for
preventing tampering with the goods, consisting of the bridge piece through
which the drawer slides, the serrations on the drawer surface and the spring
pressed drop plate a, all arranged and adapted to operate, substantially as described
and illustrated in the drawings.
3. The construction and arrangement of coinfreed delivery mechanism, sub-
stantially as herein described and illustrated in the accompanying drawings.
Dated this Twenty-first day of June 1899.
