PROVISIONAL SPECIFICATION.
Improvements in Coin Freed Apparatus for Exhibiting Series of
Photographs.
I, CECIL WRAY, of Borough Mill, Manchester Road, in the City of Bradford,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in coin freed apparatus (commonly called
penny-in-the-slot machines) for exhibiting series of photographs or animated
pictures, particularly applicable to the film operating mechanism for which
Letters Patent were granted to me jointly with Humphery James Oulton on the
13th June 1898 and numbered 13162.
For this purpose I mount the said film operating mechanism in a suitable case
large enough to contain the film or films and illuminating device. The film is
illuminated from behind and the picture is projected by a suitable lense onto a
prism which reflects it in the direction of a conveniently located external eye
piece or viewing lense.
The film mechanism may be operated by a spring, electric or other motor or by
an external handle. In the latter case the requisite speed may be obtained by a
suitable train of wheels. Any suitable form of coin freed mechanism is employed
and the number of revolutions of each movement is controlled by a stop or pro-
jection on a worm wheel driven by a worm which may be on the driving shaft.
If the film is illuminated by electricity the switch may be formed upon the wheel
and move with it.

Improvements in Coin Freed Apparatus for Exhibiting Series of
Photographs.
I, CECIL WRAY, of Borough Mill, Manchester Road, in the City of Bradford,
Electrical Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described nnd ascertained
in and by the following statement:--
This invention relates to improvements in coin freed apparatus for exhibiting
series of photographs, or animated pictures, particularly applicable to the film
operating mechanism for which Letters Patent were granted to me jointly with
Humphery James Oulton on the 13th June 1898 and numbered 13162.
The film operating mechanism is mounted in a suitable case large enough to

page_text: contain the film 'or films and illuminating device. The film is illuminated from
behind and the picture is projected by a suitable lense onto a prism which reflects
it in the direction of a conveniently located external eye piece or viewing lense.
In order that my invention may be readily understood I will now proceed to
describe my improvements in connection with such mechanism, having reference
to the accompanying drawing in which Fig. 1 illustrates in side elevation, and
Fig. 2 in plan view, mechanism or apparatus constructed and arranged in accord-
ance therewith.
The film mechanism is operated through the medium of a driving shaft A,
rotated by a motor or by an external handle. In the latter case the requisite
speed may be obtained by a suitable train of wheels. The form of handle pre-
ferably employed is one which is frictionally connected to the shaft, whereby the
handle may still be revolved while the shaft A is locked, the frictional connec-
tion being sufficient to drive the mechanism, when the shaft is released.
Fixed to the driving shaft A is a wheel B and a worm C, which latter gears
into a worm-wheel D carried upon a vertical shaft E. The worm-wheel D is pro-
vided with a tappet pin F and is also formed with a recess G. A balance lever H
is pivotally mounted at J, and is formed with a projection K, adapted to enter
the-recess Gin, the worm-wheel D). A detent L is formed upon the balance
lever H and is adapted to engage with a pin M carried upon the wheel B.
spring actuated lever N is pivotted at N' below the end of the balance lever H, and
extends forward into the path of travel of the tappet pin F.
A
The end H of the balance lever H, is formed. with a slot P through which a coin,
for operating the mechanism, is capable of passing; and below the slot P there
is a slot, formed in the end of N2 of the lever N, and arranged, so that when the
lever N is in its normal position, as illustrated in the drawings, the coin when
placed into the slot l' is retained, until the lever N is moved under the action of
the tappet pin F into the position indicated in dotted lines at Figure 2, where-
upon the coin is free to pass through.
When the film is illuminated by electricity, I form the switch for lighting and
extinguishing the lamp, by mounting an insulated contact plate R upon the
worm-wheel D) and having two spring contacts S and S¹ in connection therewith,
the plate R being cut away at R' and exposing the insulating material. The con-
tact S is arranged in the path of the travel of the cut away part R¹, whilst the
contact S is always touching the plate R; so that, when the plate R is in the posi-
tion shown, the electrical circuit is broken; but when the two contacts S S are
in contact with the plate R, the circuit is completed.
The action of the apparatus is as follows:-
Upon inserting a coin into the machine it passes to the slot P', and by its weight
causes the lever H to rock into the position indicated by the dotted lines Fig. 1,
and thereby releases the driving shaft, which may now be rotated by means of
the hand-wheel above referred to. As the worm-wheel I rotates, the cir-
cuit to the lamp is completed and the film illuminated, and the tappet pin F in
its travel engages the lever N, releases the coin, and allows the balance lever 'H
to rock until the projection K bears upon the surface of the disc D), and when the
recess G passes under the projection K, the balance lever H falls into its normal
position, and the detent Ĺ engages the pin M, thereby preventing the driving
shaft from further rotation, and simultaneously cutting off the electric light.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In coin freed apparatus for exhibiting series of photographs providing con-
trolling mechanism consisting of, a worm-wheel, driven by a worm, the worm-
wheel being formed with a recess, a projection to take into the recess, and coin
actuated means for removing the projection from the recess, for the purposes
herein set forth.

page_text: 2. Mechanism as claimed in Claim 1 in combination with an electrical switch,
arranged and acting substantially as herein set forth.
3. The general arrangement and construction of mechanism forming the
improvements in coin freed apparatus for exhibiting series of photographs, sub-
stantially as and for the purposes hereinbefore described with reference to the.
accompanying drawing.
