Improvements in Automatic Photographing Machines.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
leclare 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
tatement:-
My invention has for its object the production of an automatic photographing
machine in which the action of the various operative mechanisms are in part
controlled by a suitable fluid under pressure as distinguished from rigid connec-
tions. The invention further provides in combination with the foregoing, a motor
of any suitable construction which is adapted to so control and regulate the flow of
the fluid under pressure to the various operative parts, that the latter shall perform
Means are also provided by
their several functions in their proper sequence.
which the operative parts of the machine are set in motion by the insertion of a
coin of proper value.
I will describe an automatic photographing machine embodying my improve-
ment, aud then point out the novel features in a claim.
In the accompanying drawings,

Figure 5 is an outline view of a series of cams and their coacting parts.
Figure 6 is a longitudinal section showing the construction of an engine
which may be utilized for actuating any of the mechanisms comprised in the
machine.
Similar letters of reference designate corresponding parts in all figures.
As my invention is directed toward the production of various mechanisms and
devices which are necessary for the purpose of carrying a sensitized plate through
the various operations and movements incident to the production of a completed
photograph and its delivery to the outer portion of the machine, and the adaptation
of these parts as well, to enable them to be operated in part by a suitable fluid
under pressure, I have shown such parts as are essential to my invention, in detail.
Other parts to which my invention does not relate are not so shown, or are omitted
altogether.
A is the enclosing box or chamber within which the mechanisms and devices
constituting the improvement are contained. It may be of any suitable shape or
material, and is provided in one of its walls with an inwardly convergent tube or
light shaft B. A lens tube B¹ may be secured to the inner or smaller end of the
light shaft B, and carries a suitable lens or arrangement of lenses, B. The light
shaft B is preferably convergent inwards, or cone shaped, as this form will assist

page_text: in the concentration of the light upon the lens B2, and permit of a considerable
variation in the height of the subject posing in front of its outer orifice.
A plate holder C is arranged at the rear of the lens B2, at such a distance there-
from that the image of the subject situated at a convenient distance in front of the
orifice of the light shaft B will be properly formed upon the sensitized plate
contained within the plate holder. A divergent tube C" may be secured at
the rear of lens tube B¹, and extended rearward to the vicinity of the plate
holder C.
D is a shallow box placed immediately at the rear of the lens tube B'. It may
be secured to the lens tube while the divergent tube C' may be attached to its
opposite face. The box D is provided with an opening D' in the extension of the
focal axis of the lens B2, the opening being controlled by a suitable shutter D³,
here shown as being sector like in form and pivoted at its end portion within the
box D by a pin d. The shutter D2 is provided with an arm d'extending on the
side of the pin d opposite to that on which the main body of the shutter is situated,
and suitably connected with the piston rod d2 of an engine d³ supported on one of
the walls of the box D.
In the present instance, for controlling the movements of the operative
mechanisms, I have shown engines which are provided with reciprocating pistons
whose piston rods are in direct engagement with the moving part or parts of the
various mechanisms. These cylinders may be of the general construction
represented in Figure 6, in which E is a cylinder, E¹ the reciprocating piston,
e the piston rod attached to the piston and passing outward through a suitable
stuffing box el at the end of the cylinder. A spring e2 may be utilized to return.
the piston to oue end of its stroke. It is designed that the piston shall be moved
in the direction opposite to that in which it is forced by the spring, by a suitable
fluid under pressure admitted to the cylinder, which, after performing its function
in moving the piston to the end of its stroke, will be exhausted through a suitable
duct or passage.
I do not wish to be limited to the use of a spring as a retractive device,
however, as other means or equivalents may be employed. For instance, a weight
may be attached to the moving part by a cord running over suitable pulleys, or
the spring may be placed outside the cylinder.
Any suitable fluid under pressure may be utilized for moving the pistons. For
instance, air or water; but I prefer air, making the machine thereby throughout,
pneumatically operated.
A convenient framework or standard F is supplied for carrying and supporting
the various parts of the machine.
G is a plate magazine or box carrying the supply of sensitized plates. It may
consist of an oblong box whose interior transverse dimensions correspond with the
dimensions of the plates. The plates may be fitted in grooves go provided in the
sides of the box to maintain them in an upright position. G₁ G₁ are guide ways
or tracks on which the magazine G may slide to and fro. G2 is a chute secured
below the magazine G, but independent therefrom, and serving to direct the down-
wardly moving plate from the magazine G to its proper position relatively to the
leus B2 where it is held by the plate holder C, presently to be described.
For the delivery of the plates from the magazine G, one after another, I
contemplate, in the present instance, giving to the magazine a step by step move-
ment; the distance the magazine is carried at each step corresponding to the
distance between the plates in the magazine. The magazine G is provided with
an independent bottom plate g, which is prevented from moving with the
magazine G by a stop g', and consequently, as the magazine is moved forward, the
plates will be delivered to the chute G in succession, descending through
the latter to the plate holder C.
1 have shown a convenient way of imparting to the magazine G a step by step
movement. Its outer surface is provided with a series of ratchet teeth g
see Figure 4 more especially, with which engages a finger g³ fitted into a suitable

page_text: opening in a pivoted lever g and thrust into engagement with the teeth g³ by
a spring 9. The piston rod 9 of a cylinder g' is adapted to swing the lever g*
about its pivot or fulcrum point 98. It is evident that a reciprocation of the piston
rod will impart to the magazine G an intermittent or step by step forward
motion.
H H are retaining jaws forming the plate holder C and serving to grasp the
plate as it descends through the chute G2 and hold the same at the rear of
the lens B2. The jaws are pivoted by pins hh, to a supporting plate /', which is
itself carried by a suitable appurtenance of the supporting framework F: The
inner ends of the pivoted jaws H H may be provided with pins h² ², to engage
with a notched plate 3 carried at the extremity of the piston rod h of cylinder h³.
An outward movement of the piston of the cylinder will effect a disengagement
of, and an inward movement of the same will effect an engagement with, a plate
interposed between the jaws H H.
I is a carrier whose purpose is to depress and to withdraw the exposed plate into
and out of the several solutions necessary for its development, fixing and washing,
and finally to deliver the plate to a delivery chute.
It will be seen to comprise a slotted frame I' through which the plate may move,
a holding dog 12 which is pivoted to the side of the frame and may be swung into
and out of the slot, to pinch the edges of the plate against the frame holding the
plate, or to disengage it from the frame entirely.
13 is a cylinder carried by the frame I', whose piston rod i engages with an arm
of the pivoted holding dog 12 to swing the dog into and out of the slot of the
frame I¹. A spring may be used to insure the withdrawal of the dog I2 from
the slot.
I are upright cylinders attached to a stationary bracket and having piston
rods which engage with and give the carrier I a vertically reciprocating
motion.
The movements of the jaws H H, the frame I and the holding dog I2 are so
timed that the dog will have forced the edges of the plate against the sides of the
slot of frame 1' before the jaws H H have relinquished their hold upon the sides
of the plate.
K is the movable bath or vessel for holding the various fluids to develop, fix
and wash the exposed plate. It is shown in the form of a box comprising four
compartments K', K2, K³, K. The developing and fixing solutions may be placed
directly in compartments K, and K2 respectively, but I prefer to use separate cells.
for containing the solutions, and insert the cells in the compartments.
The movable bath K is provided with suitable rollers k, k, k, k, which travel
upon a suitable track that may consist of the upturned leg of angle irons k¹, k'.
The piston rod K' of cylinder Ke serves as a convenient means for causing the
reciprocation of the bath K.
The compartment K³ contains the washing water, while the last compartment K*
receives the washed and finished plate, from whence it passes to the delivery
chute L.. The compartment K is provided with a slide Li forming the bottom of
the compartment, which may be moved to one side, permitting the developed and.
washed plate to fall through. This displacement of the slide L' takes place when
the compartment K is directly above the mouth of chute L. The slide L' is
provided with a tongue L2 which enters a recess in a block L³ secured to the under
surface of the bath K. A spring continually presses the tongue L2 outward,
tending to close the opening through the bottom of the compartment K. A stop l¹
is interposed in the path of a shoulder 12 provided on the slide L¹.
The impetus of the bath K, as it moves forward with the finished plate in
compartiment K under the influence of the spring of cylinder K or other
retractive device, is sufficient, as the stop l' and shoulder engage to compress the
spring carrying the slide L¹ from under the compartment K', when the plate
passes downward to the delivery chute L, and thence outward.
I have shown a series of valves M, M1, M2, M3, M4, M5, M6, M7, for controlling

page_text: the flow of the motive fluid to and from the several cylinders for actuating the
various mechanisms comprised in the machine. In the present instance, I have
shown a separate valve for each cylinder. Each valve may be carried on a
bracket m, supported in any suitable manner.
Each valve comprises a chambered block m¹ within which is fitted a rotary
plug m² provided with a stem m³. A cover plate may be provided to enclose
the plug m² within the block m¹. Each valve block m is provided with three
ports mo, me, m², one (see Fig. 2), in the present instance m', being at the top,
while the remaining two m³, me, are at opposite sides of the block. The port m at
the inner side of the valve block m' of each of the valves, except valve M³, is
continued through a suitable conduit m³ to a supply chamber M containing the
motive fluid under pressure. The port m at the opposite side forms the exhaust,
while the port m' at the upper portion of the block is continued upward through
a suitable conduit to the corresponding cylinder.
As illustrated, port m' of valve M is continued through a conduit m' to the
cylinder whose piston actuates the shutter D2. Port m of valve M¹ is
continued through a conduit m10 which branches at its upper end and enters
cylinders 1, 14, whose pistons actuate the carrier I. Port m' of valve M² is
continued through a conduit m to the cylinder 13 whose piston actuates the
dog 12. Part of this conduit will consist of flexible tubing to permit of the
vertically reciprocating movement of the cylinder 13 as it moves to and fro with
the carrier I. Port m of valve M3 is continued through a conduit m to the water
compartment K3 of the bath K. A portion of this conduit will also preferably
consist of a flexible tubing to permit of the reciprocation of the bath. Port m of
valve M is continued through a conduit m¹³ to the cylinder g' whose piston
actuates the plate magazine G. Port m' of valve M is continued through a
conduit m to the cylinder K whose piston actuates the bath K. Port m' of
valve M is continued through a conduit m15 to the cylinder 45 whose piston actuates
the jaws H H. Port m of valve M' is continued through a conduit m to a
cylinder N whose piston may be utilized to actuate a slide N' to control the slot or
opening for the insertion of a coin. This slide may consist of a swinging arm to
which the piston rod N2 of the piston with which the cylinder N is supplied,
engages to shift the slide across the slot opening to prevent the insertion of a
second coin while the machine is in process of finishing an exposed plate. After
the plate has been delivered, the slide N' will be swung to one side, away from the
slot opening.
The rotary plug m² comprised in each valve, is provided with an angular
passage m extending through it, which, at one end of the movement of the plug,
will throw the ports me and m' into communication, and at the other end of its
movement, will throw the ports m' and m into communication. Hence when the
plug m² of either of the valves M, M, M2, M3, M4, M, Me, M' is moved to
one end of the movement, pressure will be admitted to the corresponding
cylinder, while, at the opposite end of its movement, the motive fluid will be
exhausted from the cylinders, the piston of which will be returned to its normal
position under the influence of the spring or other retractive device.
For the purpose of operating the plugs m² of the various valves, I have supplied
the stem m³ of each plug with a lever arm O, whose free end is pivoted to one arm
of an elbow lever O'. There are as many of these elbow levers O¹, and lever
arms O, as there are stems m³ ; but for the sake of clearness, in Figure 1, 1 have
shown but one, but it will be understood that there is one for operating each
plug m²
.
These elbow levers O¹ are fulcrumed to a shaft O2 carried in suitable
brackets 03, 03 supported by the machine. The outer end of the free arms of
each elbow lever O is brought into engagement with the periphery of a suitable
peripheral cam, by a spring Oʻ. I have shown eight of these cams, one for
actuating each elbow lever O' and consequently each plug m².
Cam P, operates the plug m² of valve M; cam P that of valve M'; cam F

page_text: that of valve M2; cam P³ that of valve M3; cam P4 that of valve M'; cam P
that of valve M5; cam P6 that of valve Me; and cam P' that of valve M².
Ps is the cam shaft to which the several cams are affixed. It rotates in suitable
bearings P, P, and is given an intermittent forward motion through the medium
of a star wheel Po attached at its extremity.
As the proper operation of the mechanisms comprised in the present invention
will necessitate five distinct periods of rest, including that in which the parts have
assumed their normal positions, comprising the exposure, the retention in the
developing solution, the retention in the fixing solution, the washing and the return
to the normal position assumed after the final deposition in the receiving com-
partment of the bath, K, and the movement of the bath forward depositing the
finished plate into the delivery chute L, I have divided the complete rotation of
the cam shaft P into five separate steps, separated by periods of rest. Consequently,
the star wheel P10 will comprise five fingers or arms. R is a disc provided with a
series of pins r, in the present instance comprising five, projecting, from the inner
radial face, the pins being adapted to contact with and impart to the star wheel P10
an intermittent inotion as the disc is rotated. These pins may be made adjustable,
if desired, whereby ready means are offered for regulating the length of the periods
of rest of the cam shaft P8.
I have shown a suitable motor for rotating the disc R. It is seen to comprise a
drum R within which may be coiled a spring, not shown, in the usual mannes, a
regulator R, a train of intermediate gearing R, and a pair of bevel wheels R*, R,
for transmitting motion to the shaft of the disc R. I have shown this form
merely for illustration, but I do not wish to be confined to its use, as other forms
and arrangements of driving mechanisms or motors may be advantageously utilized
without departing from the spirit of my invention.

parts of the motor, and when so engaged, locking the same from movement.
may consist of a pivoted bar with one or more teeth.
At its free end it extends immediately above one arm of a double armed lever St
pivoted to a standard S2. The opposite arm of the double armed lever S' is
provided with a pocket s which is placed immediately below the lower end of the
coin chute S³.
Normally the lever S¹ is in a horizontal position, but when a coin is received
through the chute S and drops into the pocket s, the lever S becomes over-
balanced, the end carrying the coin descends, the opposite end ascends, raises the
detent lever S, disengages the motor, which thereupon rotates the dise R and
actuates the cam shaft. Ps.
When the teeth of the detent lever S are again in alignment with the notches
provided for them, they re-enter the same, locking the motor from further
movement.
The coin has in the meantime descended until the floor of the pocket a has
assumed a horizontal or slightly inclined position, when the coin rolls out through
the open end of the pockets and, drops into the casing A. The lever S' then
assumes its normal position.
Tis a vibrating lever forming a latch fulcrumed at t to a pin carried by a
bracket attached to the framework F. Its upper end is adapted to enter and
withdraw from notches 2 provided in a plate 3 secured to the under side of the
bath K. Its lower end contacts with pins or studs t, t provided on the cam P³,
which operate to throw the upper end of the lever T out of engagement with the
slots of plate t, while a spring is applied to withdraw it into engagement with
the slots.
I have shown in Fig. 5 the several cams removed from their shaft, and have also
divided the angle subtended by the are traced by any point on the cam during a
complete revolution of the latter, namely 360°, into five equal parts representing
the five successive movements during the intermittent movement of the cam shaft.
Thus 1-2 represents the movement during the first fifth of the full rotation;

page_text: 2-3 that during the second fifth; 3-4 that during the third fifth; 4-5 the
fourth fifth; and 5-1 that during the last fifth. I have also shown the free end
of each elbow lever O' in the position which it assumes in the machine relatively
to its respective cam.
With the assistance of the figure, the operation and sequence of movement may
be described as follows:-
Assuming that a coin has been deposited in the coin slot, has descended the
chute S and passed into the pocket s, thus disengaging the motor in the manner
already described, the dise R revolves, and the first pin r of the same contacts
with one of the fingers of the star wheel P10. Before any movement has taken
place, the cams and ends of elbow levers O' are in the relative positions shown in
Fig. 5. During the first fifth of the complete rotation of the cam shaft P namely,
from 1 to 2, which terminates after the first pin has passed out of contact with the
first finger of the star wheel, cam. P operates to rotate the plug m² of valve M, to
open communication between the perts m and m' of said valve. This movement
takes place owing to the fact that cam P is reduced in diameter, for a portion of
its circumference, the free end of the elbow lever O' dropping into the recess
produced by this reduced portion, and shifting the plug of the valve in a manner
evident from the foregoing description. By this movement the motive fluid is
admitted to cylinder da, and the shutter D' is opened and held open for a space of
time almost equal to a fifth of the revolution of the cam. Just before the cam
reaches the end of its first movement, the elbow lever O' is shifted back to its
original position, thereby throwing ports me and m' in communication when the
motive fluid is exhausted from cylinder d³ and the shutter D2 is moved back to its
normal position, closing the opening for the exposure of the plate.
It is evident that during this portion of the movement, no function is performed
by cams P, P, P, P and P. Cam P, however, is provided with a notch in its
periphery between points 1-2. Consequently, during this movement, plug m² of
valve M will be operated to admit the motive fluid to, and exhaust it from
cylinder g'. This will operate in the manner already explained to carry the plate
magazine forward and deliver a plate to the carrier C. On comparison of cams P
and P as represented in Fig. 5, it is evident that cam. P will operate before
cam P; hence, before the shutter D is moved to one side, a plate will have
descended into the holder C.
Immediately after the operating motor of the machine has been set in motion by
the insertion of a coin, cam P7 will operate to admit the motor fluid to cylinder N,
shifting the slide N' across the coin slot, and closing the same. It will preferably
remain closed during the entire operation of the machine.
The several cams will now remain in the position where the free ends of the
elbow levers O2 are at the point 2 until the second pin of dise R will have contacted
with the second finger of star wheel Pio During the movement 2-3,
cams P, P3, P4, P are inoperative. Cam P will be the first to operate during
this movement. It will operate the plug m² of valve M2, to admit the motive fluid
to cylinder 13, thrusting in dog 12 to grasp the plate in carrier I by its upper edges.
It will be thus held during the succeeding manipulations of the plate. Cam P
will be the next to operate, shifting the plug m of valve M to admit the motive
fluid to cylinder 1, releasing the grip of the jaws H H upon the plate. Lastly,
just before the cam shaft comes to rest, due to the passing of the second pin on
disc R out of engagement with the second finger of star wheel P, cain P will
operate to shift the plug m² of valve M, admitting the motive fluid to
cylinders 1, 1, which move the carrier I downward and thrust the plate into the
developing solution carried in compartment K. The various cams have now
reached position 3, and the plate is held suspended in the developing solution 1
until the third pin of disc R has contacted with the third finger of the star
wheel P
Immediately upon the commencement of the movement 3-4, pressure is released
from the cylinders I, I, and the carrier I is drawn upward by the spring within

page_text: the cylinder or other retractive device, and the operation of cam P³ soon follows
to shift the plug m² of valve M to admit the motive fluid to cylinder K to move
the bath K backward from the position shown in Figure 1, so that the fixing
solution carried in compartment K' shall be immediately below the plate carrier I.
To permit of this backward movement of the bath, it must be unlocked from
latch T. To this end, the pius t, t extending from cam P are so arranged that
one of them has oscillated the latch on its pivot pin, to throw it out from engage-.
ment with a slot 12 in the plate 3 affixed to the bath K, but has left it free to be
withdrawn into the next slot by the spring to. Pressure may be kept upon the-
piston of cylinder K during the remainder of the operation of the machine and.
its movenient controlled by the latch T.
The cams have now completed the third fifth of their movement, and the
carrier has descended with the plate into the fixing solution carried by
compartment K', in which it is held suspended until the fourth pin of dise R has
moved into engagement with the fourth finger of star wheel P10.
The movement represented by 4-5 now takes place hath K is released, shifted.
backward a step to bring the water compartment under the carrier by the oscillation.
of latch T by a second pin on cam Ps, as already described.
At the completion of this movement, the carrier I and the plate held therein,
descends into the washing water in compartment K³, as is evident from the
construction of cam P, and is there held until the fifth pin of disc R has moved
into engagement with the fifth finger of the star wheel Pio.
At the completion of the fourth fifth of the movement, cam' P³ also becomes
operative, as it is provided with a notch on the radial line 5. It operates to
shift the plug m² of valve M³, admitting water to the compartment. Preferably,.
with the water as it passes to the compartment, there will be admitted a quantity
of air to keep the water in greater agitation, thereby more thoroughly washing
the plate.
It is not essential that there should be a separate cylinder for controlling the
cock for the inflow of water. If water is used as the motive fluid for the cylinders,
port of the valve M³ will be permanently closed, and the construction of the
plug and the valve may be otherwise the same as the other plugs and valve
blocks. If air is used, the port m³ may be permanently closed and a water supply
connected with port me, or port me may be closed and water supply connected with
the port m. Of course the various parts connected to the plug m² of this valve
will be properly related to open and close the valve at the proper time. A flexible
tube V carries off the overflow from chamber K³.
Further movement of the motor carries the fifth pin of disc R into contact
with fifth finger of the star wheel P10, and the cam shaft has commenced the
movement 5-1. Cam P¹ operates to withdraw the plate from the compartment K³,
cam P³ to shut off the flow of water, and the latch T is withdrawn to permit the
backward movement of the bath to its furthermost backward position, in which
compartment K of the bath is directly under the plate.
The dog 1 is now released by the action of cam P, the suspended plate drops.
into compartment, and the jaws H H come together to receive and support the
next plate through the action of cam P, which operates to release the pressure
from cylinder A, the piston of the same being thus forced outward in a manner
well understood.
Further, rotation of the cam shaft Pe releases the pressure from cylinder K
through the means of cam P and intermediate mechanism. The bath K is carried
forward by the retractive device to the position shown in Figure 1, slide Lis
drawn aside, and the finished plate descends through the delivery chute in a
manner already described.
Before the cam shaft has completed its movement, the pressure has been
released from cylinder N and the slide withdrawn from the coin slot.
The parts have now returned to their original position, and are ready to again.
be set in operation by the insertion of a new coin.
