Improvements in the Construction of Machines Controlled by Coin-
freed Mechanism.
We, THOMAS WILLIAM IDLE, of 40, Station Road, Willesden, in the County
of Middlesex, Engineer, and FREDERICK ERNEST PEARCE, of 39, Crystal Palace
Road, East Dulwich, in the County of Surrey, Commercial Traveller, 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 coin-freed machines such as that described in the
Specification to Letters Patent No. 16,530, A.D. 1888, and consists in certain
improvements whereby, first, the opening for the delivery of the goods is closed
automatically after the sale of each article, secondly, a coin cannot be put into the
coin-slot after the last article has been withdrawn, thirdly, wrong coins are rejected,
and, fourthly, the use of the machine is facilitated.
In the accompanying drawings,
Fig. 1 is a front elevation of a portion of a machine embodying the present
improvements; Fig. 2 being a corresponding view, partly in horizontal section on
the line 2, 2 in Fig. 1, and partly in plan.
Fig. 3 is a transverse vertical section on the line 3, 3 in Fig. 1.
The following views are drawn to a larger scale.
Fig. 4, which is a vertical section through the receptacle in which the goods are
placed, shews the means employed for closing the coin-slot; Fig. 4 being a plan
of the slide and accessory parts, Fig. 4" an end elevation of the bracket to which
the lever is pivoted, and Fig. 4º an end elevation of the connecting rod.
Fig. 5 is a transverse vertical section through the coin-shoot; the oscillating
lever adapted for the reception of the coin being also shewn.
Fig. 6 is a plan of the oscillating lever; Fig. 6 being a front elevation of the
adjustable weight by which the action of this lever can be regulated to suit
various coins.
Fig. 7 is a cross section corresponding with Fig. 6.
Fig. 8 is a transverse vertical section representing the tongue for pushing out the
articles contained in the receptacle.
Fig. 8 is a front elevation of the bearing bracket for the pulley.
Figs. 8 and 8° are respectively a side elevation and a front elevation of the
bearing bracket for the bell-crank lever.
Fig. 9 is a plan of this bell-crank lever and of the slide; the latter being used
for closing the opening provided for the withdrawal one by one of the articles to.

Fig. 10 is a view, partly in plan and partly in horizontal section, illustrating the
pull-piece and the tongue above referred to.
Fig. 11 is a transverse section through the pull-piece; the tongue being shewn
in front elevation.
Fig. 12 is an elevation of the weight for taking back the parts into their normal
positions.

a window b through which the goods can be seen. C are the coin-slots; any wrong
coins that may happen to be dropped into the slots C escaping from the slots C.

Gis the weight for causing the parts to return to their original
A bell-crank lever E' E is mounted to rotate on a pin E' supported in a
bracket E secured to the under side of the partition A The notched short
arm E of this lever engages with a projection on a guide E7 attached to the
under side of the tongue E2; the guide working in a slot A* in the partition.
The long arm E of the lever is connected to a slide Es, which serves to close
the opening D.
A weight B (Fig. 4) is placed on the top of the column of goods in the
receptacle B. This weight is furnished with a projection B2, which slides in a
groove in the side of the receptacle. When the weight has nearly reached its
lowest position, the projection B3 engages with the arm B3 of the lever B³ B₁;
thus causing that lever to turn on its pivot B (which is supported by a bracket Be
secured to the side of the casing). The movement of the lever B³ B* is com-
municated through the rod B7 to the lever B8 B, which is pivoted on the pin B10
(screwed into the casing) and is also connected to the slide B"; the latter
controlling the slot C.
The coin-shoot is arranged between two side-pieces H and H¹ (Figs. 2 and 5).
A coin of the right size slides down two inclined ledges, one of which H* is shewn
in Fig. 5, into the passage H2, whence it is guided by the incline H³ to the coin-
tray F of the lever F F A coin which is too small would fall between the ledges
on to the incline H, along which it would slide until it escaped by way of the
slot C', which may be furnished with a trough for catching the coins so escaping.
The cross-head E' is provided on each side with an anti-friction roller e. On the
arm F of the lever F F is mounted a weight F, the position of. which on the arm
can be altered, so that, by moving the weight toward or away from the fulcrum of
the lever, the action of the lever can be regulated to suit the particular coin it
is desired shall operate the machine. The weight G is connected by a cord
to the pin in the pull-piece E. The cord passes over a pulley G, which
turns in a bracket G' supported by the partition A¹.
The action of the parts is as follows:-A coin of the proper size, when dropped
through the slot C, slides down the ledges into the passage H³ and on to the
incline H³, whence it falls into the tray F. The lever F F' then turns on its
fulcrum far enough to bring its arm F clear of the cross-head E¹. The further
downward movement of the tray F¹ may be arrested by a spring, or in
any other
convenient manner. The pull-piece E can then be withdrawn. "The withdrawal
of the pull-piece causes the cross-head to slide against the under side of the arm F,
thus turning the lever F F far enough to cause the coin to drop out of the tray Fi
into the coin-receptacle. At the same time, by the movement of the guide E'
attached to the tongue E on the cross-head, the lever E³ E is turned on its pivot
so as to depress the slide E'; the said tongue E2 forcing the lowest article in the
column through the opening D on to the platform D¹. The weight G, having
been raised by the movement of the pull-piece E, falls immediately the pull-piece
is released, and causes the parts to resume their original positions ready to be
again operated after the insertion of another coin. When the last article it is
desired to sell has been sold, and the pull-piece E is pushed back, the weight B'
acts on the lever B3 B4, its arm B* raising the arm B" and depressing the arm B
of the lever Be B°; thus causing the slide B₁ to block the slot & in. order to
prevent other coins from being dropped therethrough.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, we claim :-
1. For the delivery of prepaid goods, the improved construction of machine con-
trolled by coin-freed mechanism, operating substantially as described with reference
to the accompanying drawings, and provided with means whereby the opening for

page_text: the delivery of the goods is automatically closed after the withdrawal of each
article, and whereby the coin-slot is blocked upon the withdrawal of the last
article.
2. In a machine of the kind herein referred to, the combination, with the pull-
piece E and accessory parts, of the lever E³ E and the slide E8, substantially as
and for the purpose set forth.
3. In a machine of the kind herein referred to, the combination, with the sliding
weight B¹ and accessory parts, of the slide B", substantially as and for the purpose

4. In a machine of the kind herein referred to, the combination, with the pull-
piece E, the cross-head E', the tongue E, and the weight G, of the lever F F',
substantially as and for the purposes set forth.
5. In a machine of the kind herein referred to, the combination, with the pull-
piece E, the cross-head E¹, the tongue E', and the weight G, of the weight B', the
