Improvements in Coin-freed Apparatus for Exhibiting Series of
Photographs or other Pictures.
I, CECIL WRAY, of Borough Mills, 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 for exhibiting
series of photographs or other pictures, and its primary object is to reverse the
motion of the picture film without reversing the rotation of the driving shaft.
For this purpose I mount two sun wheels on the driving shaft in such a way
that they are free to rotate thereon but not to move laterally. These wheels
have teeth on their neighbouring faces as well as on their peripheries. A planet
wheel mounted upon a radial arm rigidly fixed to the driving shaft connects
the teeth on the faces of the two wheels together consequently if the shaft is
rotated the two sun wheels turn with it but if either sun wheel is held the other
is driven at twice the speed. On the film operating shaft (or on an intermediate
shaft) a pair of similar wheels are mounted one of which directly engages one
of the sun wheels on the driving shaft and the other is connected by an inter-
mediate wheel to the other sun wheel on the driving shaft. The sun wheels on
the film operating shaft are connected together by a planet wheel mounted upon
a radial arm rigidly fixed on the film operating shaft. By this arrangement
the motion communicated to the film operating shaft can be reversed by simply
locking one or the other of the sun wheels on the driving shaft.
A
A delicate arrangement for this purpose consists in employing a separate
pinion to engage each of the sun wheels on the driving shaft and mounting two
locking wheels preferably in the same plane upon the two pinion shafts.
light locking slide is mounted between the two locking wheels and this slide
is operated by a lever pivoted below its centre of gravity and controlled by a
coin operated detent and a wheel driven by a train of wheels from the film
operating wheels.
When the mechanism is at rest the lever is held in such a position by the
detent that the locking slide is disengaged from both locking wheels conse
quently rotation of the driving shaft does not communicate motion to the film
operating shaft. But as soon as the detent releases the lever the latter falls
over to one side and actuating the slide locks one of the locking wheels thereby
enabling the motion of the driving shaft to be communicated at an increased
speed to the film operating shaft.
When the film operating shaft has been driven in this way a specified number
of revolutions a pin or its equivalent in one of the before mentioned train of
wheels engages the lever and moves it sufficiently to cause it to fall towards
the other side of its pivot and as it falls it causes the slide to release the locking
wheel with which it is then engaged and engage the other one thereby reversing
the motion of the film shaft. As soon as a specific number of revolutions have

page_text: been imparted to the film operating shaft in this direction the same pin or
another pin which may be adjustable engages the reversing lever and causes it
to fall over to its original position and again engage the detent. This move-
ment is sufficient to disengage the locking slide from the locking wheel but not
sufficient to enable it to engage the other locking wheel.
Instead of the above described reversing motion I may employ two bevel
wheels on the driving or other shaft of the machine to engage another bevel
wheel arranged to impart motion to the machine. A clutch operated in somewhat
the same way as the above described locking slide may be used to cause the
shaft to drive either of the two wheels upon it according to the direction it is
required to drive the other bevel wheel. Or the two wheels may be rigidly
mounted upon the shaft a suitable distance apart and the wheels or the shaft
may be moved to bring either one or the other into gear.
The films are preferably wound on to spools driven from the film operating
shaft and they are consequently reversed with it.
The film may be continuously driven from end to end and light intermittently
reflected upon or through it by a revolving or movable reflector or reflectors.
The picture is preferably magnified and projected downwards on to a screen
below from which it can be viewed through eye openings in a case enclosing
the apparatus.

Improvements in Coin-freed Apparatus for Exhibiting Series of
Photographs or other Pictures.
I, CECIL WRAY, of Borough Mills, 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 and ascertained
in and by the following statement: —
The object of this invention is to construct mechanism for use in coin-freed
apparatus for exhibiting series of photographs or other pictures, whereby the
driving or motor shaft which communicates motion to the film operating and
displaying mechanism and which is adapted to rotate in one direction only, may
be placed into gear with the film operating mechanism upon the insertion of a
coin, and after a predetermined number of photographs in series has been
exhibited in a forward direction, the mechanism automatically reverses the
direction of travel of the film and the same photographs are then travelled
through the machine in the opposite or backward direction, and upon com-
pleting the exhibition of the said photographs in this order. the mechanism
then automatically throws the driving or motor shaft out of gear with the film
operating and displaying mechanism, and leaves the parts in their normal or
inoperative positions ready for the insertion of a coin, and upon the insertion
of a coin the same cvcle of operations may be repeated.
In order that my invention may be clearly understood I will describe same
with reference to the accompanying drawings wherein Figure 1 is a front
elevation of one form of mechanism for carrying my invention into effect.
Figure 2 is a sectional elevation, a front plate and some mechanism having
heen removed. Figure 3 is an end elevation of the mechanism illustrated at
Figure 1.

page_text: Figure 4 is a front elevation of a second form of mechanism for carrying my
invention into effect, and Figure 5 is a plan of the same.
Referring particularly to Figures
to 3, A, A' are two sun wheels mounted
on the driving shaft B and free to rotate thereon but not to move laterally.
These wheels A, A have teeth on their neighbouring faces as well as on their
peripheries. A planet wheel C mounted upon a radial arm ( rigidly fixed to
the driving shaft B connects the teeth on the faces of the two wheels A, A¹
together, consequently. if the shaft 13 is rotated the two sun wheels A, A' turn
with it but if either of the sun wheels A, A' is held, the other is driven at twice
the speed of the driving shaft. On a shaft D through which motion is conveyed
to the film operating mechanism a pair of wheels E, E similar to the wheels A, A¹
are mounted and the wheel E directly engages the sun wheel A on the driving
shaft and the wheel E is connected by an intermediate wheel F to the sun
wheel on the driving shaft B. The sun wheels E, E on the film operating
shaft Dare connected together by a planet wheel G mounted upon a radial
arm G rigidly fixed on the film operating shaft 1. By this arrangement
motion may be communicated from the driving shaft B to the film operating
shaft D through the medium of the gearing, by locking one or other of the sun
wheels A, A on the driving shaft, and according to which one of the sun
wheels A or A is locked. the film driving mechanism is driven either forwards
or backwards and causes the film to travel either in a forward or backward
direction.
Mechanism for effecting this purpose may consist in employing separate
pinions H, H to engage each of the sun wheels A, A¹ on the film operating
driving shaft D and mounting two locking wheels J. J preferably in the same
plane upon the two pinion shafts. A locking slide K is mounted between the
two locking wheels J, J and this slide is operated by a lever M pivotted below
its centre of gravity and controlled by a coin operated detent N and a wheel O
driven by a train of wheels from the film operating gear.
When the mechanism is at rest or in its normal condition, the lever M is held
in such a position by the detent N that the locking slide K is disengaged from
both locking wheels J, J consequently rotation of the driving shaft B does not
communicate motion to the film operating shaft D. But as soon as the detent N
releases the lever M the latter falls over to one side and actuating the slide K
locks the locking wheel J thereby enabling the motion of the driving shaft B
to be communicated at an increased speed to the film operating shaft D.
When the film operating shaft has been driven in this way a specified number
of revolutions, a pin P carried by the wheel 0 engages the lever and moves it
sufficiently to cause it to fall towards the other side of its pivot, and as it falls
it causes the slide K to release the locking wheel with which it is then engaged
and engage the locking wheel J, thereby reversing the motion of the film
shaft D. As soon as a specific number of revolutions has been imparted to the
film operating shaft D in this direction, a pin 1", also carried by the wheel 0
and which may be adjustable thereon, engages the reversing lever. M and causes
it to fall over to its original position and again engage the detent N. This
movement of the lever M is sufficient to disengage the locking slide K from
the locking wheel J but the movement imparted to the locking slide is not
sufficient to enable it to engage the other locking wheel J.
Referring particularly to Figures 4 and 5 of the drawings. I will now describe
the second form of mechanism for carrying my invention into effect. Mounted
upon the driving shaft B, are two bevel wheels A, A. adapted to engage with
a bevel wheel E fixed upon the film operating shaft D: a sliding clutch J is
mounted upon the driving shaft B. adapted to engage with the bevel wheels A. A¹.
and lock either of them to the driving shaft B, or the clutch may be moved
into an intermediate and inactive position whereby both the bevel wheels are
free and disconnected from the driving shaft.
A locking slide K is provided, connected to the sliding clutch J by means

page_text: of pins taking into a circular groove formed on the periphery of the clutch,
and through which the movements of the clutch J are controlled, and conse-
quently the direction of rotation and the throwing into and out of gear of the
film operating shaft, is also controlled.
The locking slide K is operated by mechanism constructed and acting in
substantially the same manner as that of the locking slide K described with
reference to Figures 1, 2 and 3 of the drawings, and is as follows:-A pivotted
lever M is mounted upon the framework of the machine and is adapted to
engage with two stops upon the slide K. the lever M is controlled by a coin
operated detent N and a wheel O, which is driven by a train of wheels from
the film operating gear, a spring actuated lever L is also provided to impart the
same movements to the lever M, as are imparted by the weighted lever M in the
foregoing mechanism. This lever L has a projecting portion of angular forma-
tion, which under the influence of the spring, acts upon a bearing point on the
lever and causes or tends to move the lever in either direction after it has passed
the vertical position.
When the mechanism is at rest or in its normal condition, the lever Mis
held in such a position by the detent N that the slide K places the sliding
clutch J into its intermediate position, consequently rotation of the driving
shaft B does not communicate motion to the film operating shaft D. But as soon
as the detent N releases the lever M the latter is drawn over to one side and
actuating the slide K slides the clutch J into engagement with the bevel wheel A
thereby enabling the motion of the driving shaft B to be communicated to the
film operating shaft D.
When the film operating shaft has been driven in this way a specified number
of revolutions. a pin P. carried by the wheel 0, engages the lever and moves
it sufficiently to allow it to be drawn over by the lever L, towards the other
side of its pivot, and as it travels it causes the slide K to release the clutch J
from engagement with the bevel wheel A and to engage with the bevel wheel A',
thereby reversing the motion of the film shaft D. As soon as a specified number
of revolutions has been imparted to the film operating shaft in this direction,
a pin P¹, also carried upon the wheel O and which may be adjustable thereon,
engages the reversing lever M and causes it to be drawn over to its original
position and again engage the detent N. This movement of the lever Mis
sufficient to cause the slide K to disengage the clutch J from the bevel wheel A¹,
but the movement imparted to the slide K is not sufficient to enable the clutch J
to engage with the bevel wheel A.
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:
