Improvements in Automatic Coin-controlled Apparatus for Exhibiting
a Series of Photographs, Pictures, and the like.
I, FREDERIC CHARLES BAXTER, No. 5, Blucher Road, Camberwell, in the County
of Surrey, Paper Hangings Manufacturer, do hereby declare the nature of this
invention to be as follows:-
-
The object of which is to facilitate the changes in position of views of photo-
graphic or any other kind of pictures. Such pictures being mounted upon a
rotary drum which in its turn is mounted upon a spindle, and said spindle in its
turn connected to a series of toothed wheels fixed in a frame and such wheels
being actuated upon (for the required rotary or lateral movement) by springs or
drums and weights.
The whole combination being set in motion by a given size metalic disc such
disc actuating a lever for that purpose.

FREDERIC CHARLES BAXTER, formerly of 5, Blucher Road, Camberwell, but
now of 9, Gaskarth Road, Balham Hill, in the County of Surrey, Paper Hang-
ings Manufacturer, do hereby declare the nature of this invention and in wliat
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-.
This invention relates to improvements in prepayment coin controlled auto-
matic apparatus for presenting to the view a succession of stereoscopic or photo-
graphic views or representations, hereinafter referred to as pictures."
In the improved apparatus, the succession of pictures is mounted around the
periphery of a polysided drum to which (when the apparatus has been released
by the prepaying coin and is in action) motion is imparted intermittently with
intervals of rest for enabling the pictures to be viewed by means of continuously
operating clock-work mechanism, which, prior to each actuation of the drum,
is released from the control of a lever by the action of the coin, and, at the com-
pletion of each rotation of the drum, is automatically stopped by the fall of the
lever, the drum spindle being fitted with a disc having a series of equidistant
studs in number equal to that of the sides of the drum and adapted to be inter-

equidistant teeth so related to the studs of the studded disc as that the con-
tinuously rotating ratchet disc will be caused to intermittently actuate the studded
disc, and the edge of which latter is so shaped as to cause the lever when released
from the fly by the coin to support the coin containing end of the lever until the
lever escapement which has been raised by the coin from a recess in the studded
disc periphery is supported by the latter, and as then to cause the coin sup-
porting end of the lever to fall sufficiently to release the coin, and then to sup-
port the motor controlling end of the lever until, upon the completion of the
rotation of the drum, the said lever escapement re-enters said peripheral recess
in the studded disc so allowing the lever to engage with the fly and stop the
motion of the apparatus.

On the accompanying drawings:
Figure 1, represents a sectional elevation of the apparatus through 1.-1.
Fig. 2, but showing the positions of the picture carrying drum and of the viewing
lenses in dotted lines.
"
Fig. 2, represents a sectional plan thereof through 2-2 Fig. 1.
a, represents the poly-sided drum which may be adapted with flanges, a', or
with any other suitable means of carrying the series of pictures, ², one on each
of its sides. The drum is mounted on a spindle, 3, which is removably mounted
in bearings, at, respectively carried by one of the sides of the enclosing casing, b,
and the frame of the motor mechanism, c, and the rotation of the drum is
steadied by any conveniently arranged brake, bl.
The motor mechanism, c, consists of any suitable arrangement of clock-work
provided with a fly, c', or equivalent means of arresting its motion and allowing
of its renewal operation. On a spindle, c, projecting from the motor mechanism
is fitted a ratchet edged disc, c, which is adapted to engage with a series of
studs, a, projecting from a disc, a", fast on the drum spindle. The studs, a,
are equal in number to that of the sides of the drum, d, but the teeth of the
ratchet disc, c, may be of the saine or of a different number, and are at a greater
angular distance apart than is the distance, traversed by the studs of the disc, a,
in each of its movements, so that the disc, a, will be rotated by the ratchet
teeth, c³, while the latter are in engagement with the pins, , and will remain
at rest after one tooth, e³, passes out of engagement with one pin, a³, until the
next tooth, e, comes in, engagement with the next pin, , and so the continuous
motion of the motor mechanism will only operate the drum intermittently.
The motor mechanism is fitted with a controlling lever, d, a weighted end, d',
of which is adapted to engage with a radial arm, et, projecting from the fly
spindle, and the other end, ², of which lever is adapted to receive and to be
lowered by the action of the prepaying coin so as to raise the lever end, d', from
the fly arm, c. The lever is also fitted with two escapement arms, d³, d, adapted
to engage with the periphery of the disc, ", which is so shaped that, when the
apparatus is at rest, the escapement arm, d, rests in a peripheral recess, a, and
that, when the coin falls into the lever end, , and raises the arm 3, out of the
recess, a, and the lever end, d, from the fly arm, c, so as to allow the ratchet
disc, c³, to actuate the studded disc, a, as aforesaid, the disc periphery supports
the arm, ds, and the coin holding end, of the lever, causing
the coin to retain the lever end, d, out of engagement with the fly arm,
until the disc recess, has travelled beyond the escapement arm, and the
disc periphery again supports the latter, whereupon the disc periphery tilts the
arm, and lowers the lever end, , sufficiently to allow of the escape of the
coin therefrom, whereupon a concentric portion of the disc periphery supports the
arm, ³, until, on the completion of the rotation of the drum, the disc recess, a',
again presents itself to such arm allowing the latter to fall thereinto and the
lever end, d, to engage with the fly arm, c, and arrest the motor mechanism.
The pre-paying coin is inserted into the apparatus through any suitable
arrangement of chute, c, in the casing. b, which guides it into the coin receiving

falls into any suitable coin receptacle, f.

to the interior of the apparatus to illuminate the pictures, or the pictures may be
illumined by internally arranged lighting devices.
h, represents a door by means of which access can be had to the interior of
the casing.
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
In prepayment coin controlled apparatus for automatically presenting a series
of stereoscopic or photographic views or the like, in combination, a polysided
drum adapted to carry a series of pictures in a relatively fixed position, clockwork
mechanism having a fly or equivalent means of arresting its motion and allowing
of its renewed operation, a coin operated lever adapted to engage with the fly and
to release the same when operated by the prepaying coin, and an escapement
between the motor mechanism and the drum consisting of a ratchet edged dise
on the motor mechanism and a studded disc on the drum spindle the studs being
equal in number to the sides of the drum and the ratchet teeth being
adapted to intermittently engage with the studs, and the studded disc periphery
being adapted to control the coin releasing and fly engaging movements of the
lever, as set forth.
