Improvements in Apparatus for Receiving Coin, and Displaying
Stereoscopic or other Pictures or Effects in Exchange."
I, HENRY WOOLFE of 8 Halstead Road, Seacombe in the County of Chester,
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:---
This invention relates to an apparatus for receiving coin and displaying stereoscopic
or other pictures in exchange, and has for its object a more efficient mechanism than
has hitherto been employed.
In this prepayment mechanism, the movement of the pictures is obtained by means
of a clockwork run by a spring or even a weight, the clockwork having a winding
stem whose end is located on the exterior of the machine where it can be operated by
the user or attendant after the introduction of the coin. The clockwork mechanism
according to my invention however remains normally locked and is only rendered
operative by the agency of a predetermined coin inserted by the user into a suitable
orifice in the enclosing cabinet of the machine.
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a side view of the apparatus with the enclosing cabinet removed, except
a small portion thereof;
Figure 2, a back elevation;
Figure 3, a plan view of Figure 2 with a part of the mechanism removed;
Figure 4, a detail view showing the locking and releasing mechanisms with the
going barrel and other parts removed;
Figure 5, a cross sectional view of the rotary frame carrying an endless band of
stereoscopic or other pictures;
Figure 6, detail front view of the toothed gearing by which the coinfree.l clockwork
drives the frame carrying the endless band of stereoscopic pictures;
Figure 7, a side view thereof.
Figure 8 a perspective view of the disc P alone.
Referring to these figures, A is the rotary frame carrying an exdless band A' of
stereoscopic or other pictures mounted on the spindle B. This rotiry frame with its
endless band of pictures is automatically set into intermittent motion on the insertion
of a coin by a clockwork mechanism. This consists of a going barrel C containing a
main spring whose outer end is attached to the inside of the going barrel, and its
inner to the winding stem H, the going barrel has a cogwheel D'on its periphery,
which is the first wheel of the train EE, while the fly F determines the speed of
rotation of the barrel C, that is the speed of the intermittent rotation of the frame A
and its endless band of pictures.

page_text: therefore on the endless band are displayed through the eye or object glasses
during the period of one revolution of the going barrel C, the stop C¹ finally striking
against the arm L³ so that it will be stopped on the completion of one complete revo-
lution.
In order to prevent the main spring running down too far, I provide the third
arm 1 which is in one with the arms Land L¹. The action of lifting the arm L
besides moving the arm L¹ also moves the claw of the arm L2 into close proximity
with the periphery of the barrel C and in the path of the stop C¹. If the operator
turns the handle H¹ sufficiently to cause the stop H¹ to pass the clawed end of the
arm L, the dropping of the arm I will lift the arm L2 away from the barrel clear from
the path of the stop C¹, but if he should not do this the clawed end of the lever I
will intercept the travel of the stop C', and so bring the rotation of the going barrel
to a standstill at about a quarter of a revolution, and thus prevent the main spring
running down. Immediately however the operator winds up the handle sufficiently
to prevent the spring running down too far, the clawed end of the lever L falls, and
the clawed end of the lever I rises clear of the stop setting the going barrel into
motion again.
In apparatus of this kind it becomes of consequence to rotate the frame and its
endless band of pictures with a short or sharp motion, and then allow a period of
rest to allow of each individual picture being sufficiently displayed one at a time, also
to keep each picture stationary while being displayed. To secure this result the
toothed gearing N has been contrived whereby an intermittent motion is communi-
cated to the frame. It comprises a disc P fixed upon the axis of pinion & which is
driven by the barrel containing the main spring. This disc has a narrow faced
tooth Q and a wider faced tooth R. A pinion S is fitted to the axis of the rotary
frame A, and this pinion has two distinct sets of teeth, namely, the cross shaded
ones & which gear with the tooth R, and the unshaded ones s¹ which gear with the
tooth Q, the teeth R and s being double the width of Q and s¹. The pinion S is
turned onward in one direction through a definite angle, every time the tooth Q
strikes one of the teeth s¹, and through a further definite angle in quick succession
every time the tooth R strikes one of the teeth s, being locked or prevented from
revolving for the remainder of the disc's revolution, by the teeth s overlapping and
coming close to the periphery of the disc. In this manner each rotation of the
disc P will advance the pinion S intermittently through a certain space, and the
motion will continue until the stop C¹ meets the end of the lever L' when the entire
mechanism will stop working, until a new coin be inserted and the main spring
re-wound.
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 :-
