Improvements in Coin Actuated Automatic Mechanism for the
Delivery and Storage of Solidified Ices.
HERBERT YOUNG DICKINSON of 56 Gray's Inn Road London, Engineer, and
ANDREW GILLIGAN MACCULLOCH of 56 Gray's Inn Road, London, Inventor,
do hereby declare the nature of this invention to be as follows:-
We construct a receptacle of sheet metal to contain the ices. Around this there
is a second casing so as to form a receptacle for a freezing mixture. The whole is
inverted. The receptacle for ices together with freezing receptacle and lower
mechanism being withdrawn in one piece and being made to register correctly with
the top mechanism by means of grooves and slides one side of the outer case is
made detachable so as to allow access to the interior there being a rising floor or
lift under the ices in inner receptacle which is caused to rise by weights passing
over pulleys about the mouth of receptacle. The ices thus rise and come one by
one into the delivery frame which is fixed above them, this delivery frame being
similar to a drawer but having no top or bottom. The ices are prevented from
rising more than flush with the top of the sides of the drawer, by the flanges or
guides that the drawer runs in. This drawer frame is released by one, two, or
more catches raised independently from one, two, or more rows of racks of teeth,
which catches work on these racks as palls in ratchet wheels. Each pall is raised
above its rack so as to disengage from the teeth thereof by the weight of a coin.
The machine is provided with the same number of money slots as there are ratchets
and mechanism is provided to set the box by disengaging one or more palls to work
with any desired number of coins, which can be altered as required. The action
of fixing a pall closes its corresponding money slot. Each ice is enclosed in a
separate box.

GILLIGAN
We HERBERT YOUNG DICKINSON Engineer and ANDREW
MACCULLOCH Inventor both of 56 Gray's Inn Road London W.C. in the County
of Middlesex, 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 :--
This invention relates to an improved method of supplying ice creams, by means
of an automatic delivery box, and has for its special object, to deliver the ices
stored in said box in a fresh condition.
In order that the improved mechanism for the delivery of the ice creams may be
thoroughly understood in its details we will now refer to the drawings of which
Fig. 1, shows our machine half in outline and half in section.
Fig. 2 shows plan of our refrigerator.
Fig. 3, shows section of ice cream storage and refrigerator.

page_text: Fig. 1 shows a side view of refrigerator and action of weight attachment for
raising the packages.
Fig. 5, shows sectional side view of Fig. 1.
Fig. 6, shows on left hand, plan of section A. B (Fig. 5) and on right hand, plan
of section C. D (Fig. 5).
Fig. 7 shows top view of pall R.
Fig. 8 shows side view of same.
Fig. 9 is an illustration of front view of a novel arrangement for showing when
the delivery box is empty.
Fig. 10 shows a side view of same.
In carrying out our invention we employ an ordinary box A made of wood, cast
iron, or any other suitable material which serves as the outer casing or receptacle.
B is the refrigerator constructed of zinc or other suitable material, a cast iron
frame attached to the top of the refrigerator by means of bolts and nuts H¹,
slides into cast iron grooves H" attached to the inside of the lid N of the box A.
The refrigerator is made detachable so that it may be conveniently filled with
the ice creams E, which are put up in packages and charged in their receptacle,
and are kept cool by any ordinary freezing mixture. Said freezing mixture is put
into the hollow parts I of the refrigerator B (see Fig. 2).
Weights W running over pullies C in grooves G and held by strings M lift the
platform V and raise the packages to the delivery drawer Y.
The ices are prevented from rising more than flush with the top of the sides of
the drawer by the flanges or guides with which the drawer is provided.
This drawer frame Y is released by one two or more catches R, raised from one,
two, or more rows of ratchets R¹.
The catches work on the ratchets in the same manner as palls in ratchet
wheels.
The action of releasing the drawer Y is as follows.
A coin II, thrown in at slot P, passes down the slide S and falls on the
platform R of the catch R, thereby lifting the catch in the manner shown in
the dotted lines in Fig. 5, disengaging said catch from the rack and releasing
the drawer Y. The catch is provided at its weighted end with a pin q, which
when the drawer is being pulled out, runs on the guide g. (Figs. 5, 6, 7 & 8) which
is attached to the drawer frame Y. Said guide is provided for the purpose of
keeping the tooth of the catch suspended, while the drawer is pulled out and while
the coin is passing into the receptacle L. When the drawer Y is pushed back
again the coin has passed and the pin 7 of the catch falling from the guide
allows the catch to drop into its position on the racks, locking the mechanism until
it is released by another coin.
The drawer may be released by means of any other well known mechanical
principle.
A piece of brass or other suitable metal is bent in the shape shown in Figs. 9 & 10,
and is provided with a brass or other suitable shield D' showing the words "empty
and "full," the bottom or foot of this piece rests on the ice cream packages in the
receptacle. When said receptacle is exhausted the piece D will drop and the
shield will show "empty" whilst part D will prevent any coin, being passed
through the slot P.
If it is desired to have the delivery from above instead of from below we employ
the same refrigerator case B, but leave it open at the bottom, and instead of the
weight and pulley arrangement, we place on the top of the pile of ice creams a
piece of lead or other suitable weight of the same size as the ice cream packages,
to ensure the delivery of the packages into the drawer, in any known manner.
employing the last described delivery from above, we do not use the mechanism for
showing the words "empty" and "full."
In
To improve the action of the refrigerator for the purpose of cooling the ice
creams, we may employ an extra wooden or metal box containing animal hair,
charcoal, or other suitable non-conducting material.

page_text: 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. In automatic delivery boxes the special shape of a refrigerator for storing ice
creams in packages and being detachable for the purpose of replenishing the
packages and freezing mixture, as shown in reference to the annexed illustrative
drawings.
2. In automatic delivery boxes the mechanical arrangement shown in Figs. 1. 5. 9
& 10. showing whether the box is full or empty.
