An Improved Coin-freed Apparatus for Automatically Photographing
Persons and Objects and for Developing and Delivering said
Photographs.
I, ISAAC JOEL, of 20 Devonshire Terrace, Hyde Park, in the County of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved coin-freed apparatus for automatically
photographing persons and objects, and for developing and delivering said photographs.
By preference I use the ferro-type process.
The apparatus consists of a circular chamber or reservoir divided radially into any
desired number of compartments, containing the various chemical liquids or solutions
suitable for developing and fixing the photographs. The rim of this developing
reservoir forms a cam surface upon which bears a roller carried by a tray or cage
into which the plates fall after receiving the image ready to be developed. A
revolving motion is given to a spindle carrying the cage by incans of any suitable

the
upon
developing reservoir gives to the cage a rising and falling motion so that the plate
in such cage is alternately dipped and withdrawn froin each of the developing
compartments as the cage revolves. One revolution is sufficient to complete the
cycle of operations.
Upon inserting a coin into the apparatus it falls upon and depresses a weighted
pivotted lever which, in its normal position, engages with a pin, carried by one of
the wheels of the clock train, so preventing any motion, but, so soon as the lever is
depressed the mechanism is allowed to work and the cage or tray commences to rotate
around the cam track. As it rotates a cam upon it comes into contact with a disc
covering the lens aperture and causes it to be removed and exposes the plate so
permitting of the photograph being taken. The length of time that the plate is
exposed is made to depend upon the shape and size of the cam. On the further
rotation of the cage another cam upon it causes the plate bearing the image to fall
from its position behind the lens into said cage, and as the cage continues to revolve
around the developing reservoir the plate is developed by being successively dipped
into each of the various compartments. Just before the cage completes its revolution
it is caused to be tilted by the cam on the developing reservoir and the developed
photograph falls into a shoot and is delivered.
The undeveloped plates are contained in a column (which forms a dark chamber)
one above the other, and they are caused to fall into position behind the lens by
means of a slide coming behind the lowermost one and pushing it forward into a
guide which leads it into correct position to receive the image. The slide receives a
to and fro motion by means of a pin carried by the wheel above referred to and
working in a slot in the plate so giving a to and fro motion to it.

An Improved Coin-freed Apparatus for Automatically Photographing
Persons and Objects and for Developing and Delivering said
Photographs.
I, ISAAC JOEL, of 20 Devonshire Terrace, Hyde Park, in the County of London,
Merchant, 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, reference being had to the accompanying drawings and to the
letters and figures marked thereon, that is to say:-
This Invention relates to an improved coin freed apparatus for automatically
photographing persons and objects and for developing and delivering said photographs.
By preference I use the ferro-type process.
The apparatus consists of a circular chamber or reservoir divided radially into any
desired number of compartments containing the various chemicals or solutions
suitable for developing and fixing the photographs, and water for washing the same.
The inner rim of this developing reservoir is formed as a cam path track, or surface
upon which travels a roller, carried by a frame in which is pivotted a tray or cage,
into which the plates fall after receiving the image ready to be developed. A
revolving motion is given to a spindle carrying the cage by means of any suitable
clock movement. The cam surface upon the developing reservoir gives to the cage
a rising and falling motion, so that the plate therein is alternately dipped and with-
drawn from each of the compartments as the cage rotates. One revolution is sufficient
to complete the cycle of operations.
Upon inserting a coin into the apparatus it falls upon and depresses a weighted
pivotted lever which in its normal position engages with a pin carried by one of the
wheels of the clock train-so preventing any motion, but so soon as the lever is
depressed by the weight of the coin, the mechanism is free to work and the cage or
tray commences to rotate around the cam track. As it rotates a double cam upon it
comes into contact with a disc covering the lens aperture and causes it to be removed
thereby exposing the plate and permitting of the photograph being taken. The length
of time that the plate is exposed is made to depend upon the shape and size of the
cam. On the further rotation of the cage, another portion of the double cam upon it
causes the plate bearing the image to fall from its position behind the lens into said
cage, and as the cage continues to rotate around the developing reservoir the
photographic image on the plate is developed by being successively dipped into each
of the various compartments. Just before the cage completes its rotation it is caused
to be tilted by the cam on the developing reservoir and the completed photograph
falls into a shoot and is delivered.
The undeveloped plates are contained in a column, (which. forms a dark chamber)
one above the other, and they are caused to fall into position behind the lens by
means of a pusher coming behind the lowermost one and pushing it forward into a
guide which leads it into correct position to receive the image. The pusher receives
a to and fro motion by means of a pin carried by the wheel above referred to, and
working in a slot in the plate so giving a to and fro motion to such pusher.
As will be seen from the above, this apparatus is perfectly automatic in its action,
there being no handle or handles to operate, in order to assist the mechanism in any
way, as in certain other arrangements heretofore constructed.
And in order that the invention may be readily understood, I proceed to describe
the same with reference to the accompanying drawings.
Figure 1 is a side elevation.
Figure 2 a rear elevation, and
Figure 3. a front elevation of the apparatus, the casing being removed for the sake
of clearness.

Figure 7 is an elevation showing the mechanism employed for uncovering the
lens.
Figure 8 is a longitudinal section showing the mechanism for releasing the plate
after it has received the image, and for delivering it into the rotating cage.
Figure 9 is a face view of the same.
Figure 10 is a detached view in plan, of the cage, showing the double cam carried
by it.
Figure 11 shows the position the cage assumes when passing from one compartment
of the developing reservoir to another.
Figure 12 shows the position the cage assumes when delivering the finished plate.
Figures 7 to 12 both inclusive are drawn to a larger scale.
a is the framework of the apparatus is a clock-movement for actuating the
mechanism and provided with an escapement c. d, d, are weights for driving the
clock movement, but if desired, a spring may be used instead. e is the circular
reservoir divided into three, or more compartments for containing the solutions
necessary for developing, and water for washing the plates. It is preferably
constructed of glass and is provided with pipes (not shewn in the drawings,) for
introducing and drawing off the solutions and water. This developing reservoir is
carried by a plate firmly secured to the framing. g, is the spindle arranged
concentrically within the reservoir e and carrying a forked frame gx having pivotted
at its outer extremity the cage h. On one of the arms of the forked frame is pivotted
a lever carrying at its inner end a roller * which travels upon the cam path
formed on the inner wall ex of the reservoir. The other extremity of the lever i,
acts upon a stud projecting from the cage h, and by means of which the dipping
motion is imparted to said cage. is the double cam carried by one of the arms
of the forked frame g*. When the spindle g is caused to rotate by the clock
movement and bevil gearing the cage is also caused to rotate and a dipping
motion imparted to it by the roller travelling upon the cam path on the wall ex,
so causing an up and down movement of the lever * which lever by acting upon the
stud imparts the dipping motion to the cage.
I is a column or dark chamber carried by the plate and containing the super-
imposed prepared plates. It is provided with a shutter sliding vertically to
facilitate its ready refilling. A weight resting on these plates keeps the lower-most
one always in position to be pushed forward by the pusher m, having a to and fro
motion imparted to it by means of a pin m' standing out from the disc m² and
working in a slot m³ in said pusher. The disc m² is secured to the upper end of the
spindle and receives its motion therefrom. n, n are guide ways in which the pusher
works. is an aperture in the plate through which the prepared plates fall when
pushed forward by the pusher. Beneath this aperture is a guide o carried by
wings o o along which the prepared plates are guided into an upright position behind
the lens v ready to receive the image. A bent metal finger q bearing against the
back of each of these plates, holds it in this position. p is a spindle supported in
bearings on one of the wings o, (see Figure 7). One extremity of this spindle carries
a disc or shutter p', for covering the lens, the other carries a pendent finger p' which
when acted upon by the portion g' of the double cam g³, g, uncovers the lens and
allows the image to fall upon the prepared plate. The finger q (see Figures 8 and 9)
before mentioned is secured to a rocking bar q' carried in bearings qq. Standing
out from this bar is a pin q3 which is acted upon by a weighted lever havings its
fulcrum at . The lever in its normal position, keeps the finger in the position
shown by dotted lines in Figure 8; but when the cage, during its rotation, comes into
position to receive the prepared plate, the portion g of the double cam, acts upon and
raises the projecting arm so causing the finger to descend into the position shown
by full lines in Figure 8, and allow the prepared plate to fall down the inclined shoot r
into the cage.

page_text: The working of the apparatus is as follows:-a coin having been inserted into the
coin slots, falls on to the end, of the lever t, and by depressing it raises the
projection out of the path of the pin and allows the mechanism to start. The
cage, now commences to rotate, and the pusher m, pushes forward a prepared
plate which falls through the aperture into position behind the lens, as before
explained. The plate is here held until the portion g³ of the double cam acts upon
the pendent finger p² and by removing the shutter p' uncovers the lens, thus exposing
the plate for a sufficient time to enable the photograph to be taken, such time of
exposure depending upon the length of the cam . The cage continuing to rotate
then brings the other portion 2 of the double cam into position to act upon the
projecting arm and causes the finger to fall and allow the plate bearing the
image to drop into the cage, where it is retained during the remainder of the rotation
and dipped respectively into the several compartments of the developing reservoir.
When the plate has been dipped into all the compartments, the lever causes the
cage to be tilted into the position shown by Figure 12, and the finished photograph
is delivered down the shoot u to the depositor. The cage having arrived at this
position, is prevented from further motion by the pin 2 again coming into contact
with the projection on the lever and the apparatus is stopped. It is however
ready to recommence a fresh cycle of operations when another coin is inserted.
The shutter p', is shown with a projecting piece (Figure 9) formed on it for
the purpose of acting upon a lever carried by a spindle ¹, another lever on the
same spindle is provided with a coloured disc which is visible through a glazed
opening in the casing of the apparatus and indicates by its appearance or dis-
appearance, to the person using the apparatus, when his image has been received upon
the plate, and he may move away from his position, but any other suitable indicator
may be employed for the purpose.
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 automatically photographing persons and objects, the
means for dipping and delivering the prepared plates after they have received the
image, consisting in the construction and arrangement of a radially divided
developing reservoir or chamber, having a cam path on its inner wall, together with
