Improvements in Coin-operated Photograph Machines.
We, PIERRE VAN WYCK WELSH, Inventor, of 887, Third Avenue, Brooklyn,
in the County of Kings, and WILLIAM FRANCIS FREEMAN, Real Estate Agent,
of The Winthrop, 125th Street and Seventh Avenue, New York, both in the State
of New York, United States of America, do hereby declare the nature of this
invention to be as follows :→
Our invention relates to coin-operated photograph machines, that is machines
which are actuated by the dropping of a coin in a slot, the object being to take a
perfect picture and finish and automatically deliver the saine to the purchaser.
The machine is mounted on a suitable base on uprights which rise from the
corners of the base and are braced together at the top. A. counterbalanced lens
case is mounted to slide vertically between a pair of these uprights and it is
supported by a chain running over pulleys at the top of the uprights. The lens
case has an exposure opening in the front side and a delivery tray for the finished
pictures beneath it and it is provided with a chute for the coin which is delivered
upon a plate on the free end of a lever mounted on a counterbalanced shaft having
an arm which is connected to a tilting lever, said lever being pivoted near the centre
at a point above the lever carrying the coin plate and being provided at its free end
with a tripping arm adapted to extend into the path of a fan driven by clockwork
mechanism. The clockwork mechanism drives the main shaft of the machine which
extends horizontally through the back portion of the apparatus and carries cams
which effect the various operations of the several parts of the machine. On one
end of the driving shaft there is a disc having a notch in one side into which enters
a finger or pawl secured to the lever carrying the coin plate, the upper end of said
finger being bent at right angles so as to enter the slot. The slot is partially
covered by a flat spring which is secured to the circumference of the disc and the
free end of which lies loosely over the slot, the arrangement being such that when
the lever is depressed by the dropping of the coin upon its free end the bent end
of the pawl will be carried below the spring and the spring immediately flies back
to place, so that if the lever should return quickly the bent end of the pawl would
strike the spring and be prevented from entering the slot in the disc. When the
finger or pawl is removed from the disc the clockwork starts so that the machine is
operated and as the disc revolves the bent end of the finger will pass between the
spring and the face of the disc so as to again enter the slot when the latter is
brought into position to register therewith. The lens tube with which the machine
is provided is of the common form. It is arranged opposite the exposure opening
and at the front end of the lens tube there is a frame in which the shutter is held to
slide, the said shutter being provided with a rack with which engages a gear wheel
carried by a shaft on which is mounted a drumm to which is secured a cord or cable
which extends backward and downward and is attached to an arm projecting from a
sleeve on a countershaft parallel with the main driving shaft, the said sleeve having
a nib adapted to engage with a cam carried by the latter shaft. Thus at the right
time the cam will act so as to pull upon the cord, revolve the shaft and gear wheel,
and raise the shutter, and as the cam passes away from the nib the shutter will
drop back to place by its own weight. At the inner end of the lens tube there is a
fly which is adapted to swing up parallel with the opening of the lens tube in
the frame, said fly being normally held in a vertical position by a spring. The
chute in which the fly swings extends downward to the inner end of the lens tube
and through it the photograph plates are dropped. The fly is operated by a cam

page_text: on the main driving shaft and it is connected by a rod with an arm upon a sleeve
fitted loosely on the countershaft above mentioned, said sleeve having a projection
which extends into the path of the cam. When a plate is dropped in front of the
fly the fly will be held away from the lens tube by the cam and as soon as the
driving shaft starts the cam will move so as to release the arm on the sleeve
and permit the spring to swing the fly into a vertical position to adjust the
plate.
The upper end of the chute registers with an opening in the base of the feeding
mechanism which base carries the plate holder consisting of two similar and semi-
rectangular sides with an open space between them, the plates being held one above
another within the holder, and between the said sides. Extending around the
holder and at right angles to each other there are shafts which are geared together
and carry gear wheels which engage sliding racks held at right angles to the shaft
and adapted to slide on the base. The racks have projecting inner ends which are
adapted to extend beneath the plates and the shafts and racks are arranged so that
the racks will be moved at every revolution of the shaft but the racks on the sides
and ends of the holder will move alternately that is to say when the end projections
are beneath the plates, the side projections will be withdrawn and vice versú, so that
the plates are dropped one by one. The plates are provided on the sides and ends
with notches, the side notches being produced in one plate and the end notches in
the next, and the notches are adapted to slip over the projections. The plates are
of the usual kind such as are used in taking tin-types. One of the shafts is
provided with a square end adapted to receive a crank which is connected by a rod
with a gear wheel on a shaft which is held above and parallel with the driving
shaft and geared therewith, so that at every revolution of the driving shaft a plate
will be deposited in the chute. There is at one side of the holder a flexible hood
which surrounds an opening in the side of the case so that a package of plates may
be thrust in through the hood and adjusted in the machine without exposing them
to the light. Mechanism is provided for preventing all possibility of any of the
plates sticking in the plate holder, consisting of a magnet arranged to swing beneath
and against the plates in the plate holder and secured to a rod whose other end is
secured to a cranked lever mounted on a shaft which is held in suitable supports
below and at one side of the plate holder. This lever connects with a depending
and comparatively stiff spiral spring, the lower end of which is attached to a cranked
lever carried by a shaft which extends into the path of a cam on the driving shaft.
The magnet swings in a slot in the feed chute and it is normally held upward
against the bottom plate in the plate holder. As one arm of the lower crank lever
rides on the cam it will be swung so as to pull down the spring and rock the upper
lever, thus swinging the magnet upward into position to hold the same against the
plates, but after a picture has been taken the cam by the revolution of the shaft
permits the spring to assert itself and the magnet drops down and takes with it a
plate which is caught by the feed chute and delivered behind the fly. The spring
connecting the upper and lower portions of the magnet-operating mechanism enables
the magnet to strike yieldingly upon the plates, so that no harm ensues, and means
are provided to prevent the magnet from being thrown up too far.
a
The developing bath tank is arranged beneath the chute which is closed at its
lower end by a plate which extends beneath the fly and covers the top of the bath,
said plate being attached to a swinging arm which is held in a vertical position by
spring until it is withdrawn to allow the photograph plate to drop into the bath.
This is effected from the driving shaft by a cam which strikes a projection on a
sleeve on the countershaft to which a rod attached to the swinging arm is
connected. The lower end of the bath tank is cut off diagonally and is closed by a
valve which is packed to prevent the developing liquid from running out.
T'he
valve has side pieces which close over the sides of the tank and these side pieces
are prolonged upward and pivoted to a shaft journaled in suitable supports at the
back of the tank. On opposite sides of the valve there are upwardly and forwardly
extending arms which are pivoted to the valve and to pairs of cranks on a shaft

page_text: which has a weight to counterbalance the valve and which is journaled in hangers
in front of the bath tank. On this shaft there is another crank which is connected
by a rod to an arm on a sleeve on the countershaft which is acted on by a cam on
the main driving shaft. The cam is adapted to bear on the arm in such manner a
to hold the valve in position and at the proper time to permit the valve to slacken
slightly and then to drop down from the bath tank so that the liquid may escape.
When the valve drops or slightly slackens the liquid is deflected into a gutter and
thus prevented from dropping into the fixer. The tank must obviously be kept
tightly closed while the picture is being developed and to avoid the necessity of a
very nice adjustment of the levers the crank to which the rod from the sleeve is
attached is provided with a hub which is loosely mounted on the shaft and on this
hub there is a spiral spring, one end of which is fixed to the crank and the other
end to the shaft. This yielding connection enables the valve to be jammed tightly
to place without danger of breaking anything or of leakage of the valve. The
developing liquid is carried in a removable tank which is mounted in a receptacle
in the upper portion of the machine. A tube leads from the lower portion of the
tank and delivers into a bulb which holds a charge for the bath tank and which has
an outlet pipe on the under side. An air pipe extends upwardly from the upper
portion of the bulb, to enable the bulb to be quickly filled and emptied. The outlet
tube is closed by a weighted conoidal valve and this connects by a cord or rod with
a valve which is adapted to close the air inlet of the tank and consequently the two
valves may be simultaneously operated. The air inlet valve connects by a rod with
one end of a tilting lever whose opposite end connects by a rod with another tilting
lever which extends into the path of an arm on a sleeve which is secured to the
driving shaft, said sleeve having an arm which extends into the path of a projection
on a sleeve which is held loosely upon the countershaft. This sleeve has a
projecting arm which connects by a rod with one arm of a bell crank which is
pivoted on a stud beneath the tank and which has its upper arm connected with a
yoke of a pair of parallel rods which are held to move horizontally beneath the
tank, the rods being normally pressed forward by a weight on the bell crank.
These rods have at their front ends a crosshead, an arm on the lower end of which
carries a valve which enters and closes the tube leading from the bulb. The
tension of the weight will therefore normally hold the valve closed so as to stop the
tube. Beneath the outlet tube there is a funnel from which leads a tube which
delivers into the top of the bath tank. At every revolution of the driving shaft
the valves of the tank are actuated so as to charge the bulb and the developing
charge is delivered to the bath tank. When the bath tank is emptied, the liquid
flows into a gutter beneath and a little to one side of the bath tank, the shape of the
tank and the valve beneath it serving to deflect the liquid into the gutter and from
the gutter the exhausted liquid is conducted through a tube and delivered into a
waste tank.
The quick movement of the photograph plate through the tank after the picture
has been developed is ensured by a plunger which is held normally above the back
of the lens and moves downward through the chute. This plunger has on one side
a pin held to move in a guide and the plunger is held normally raised by a cord or
wire passing over a pulley and secured to a weight. The plunger has on one side a
laterally-extending stud which is adapted to rest on a tripping lever as hereinafter
described and the plunger has also a laterally-extending perforated arm which
extends into the path of a stop on the cord and consequently the stop and arm will
move up and down together, the stop serving to hold the plunger in a raised
position. The cord extends downward and backward through the case over guide
pulleys and its lower end is fixed to a drum which turns loosely on a shaft at the
back part of the case and at right angles to the driving shaft with which it is
geared. At one side of the drum is a collar which is fixed to the shaft of the drum
and projecting from one side of the collar and parallel with the sides of the drum is
an arm to which is pivoted a lever and the latter is pressed by a spring against the
side of the drum so as to engage a stud on the drum and consequently when the

page_text: collar is turned the drum will be carried with it. The lever is bevelled or inclined
on the side next the drum and extending into the path of the lever is an oppositely-
inclined arm which is fixed to a suitable support and when the arm comes in contact
with the lever the lever will be forced away from the drum thus permitting it to
free itself from the stud and this will provide against the drum's making more than
one revolution at a time and will also permit the counterbalance or weight to return
the drum and plunger to their normal positions. To further guard against the
drum turning more than a revolution and to permit it to oscillate slightly at the end
of its stroke, a lever is pivoted loosely on the drum and held to play loosely on studs
and the free end of the lever projects outward so as to engage a fixed stud held to
an adjacent fixed portion of the case. The lever will first strike the stud on the
under, and then on the upper, side and the movement of the lever will permit the
drum to turn a complete revolution. The plunger is held upward by a bell crank,
one arm of which engages the pin on the plunger and the bell crank has its lower
arm held to swing upward against the stud and is normally held against the stud
by a spiral spring. A rod leads downward from the bell crank and connects with
another bell crank which is pivoted to the frame and the lower arm of this bell
crank connects by a rod with an arm of a sleeve held loosely to the countershaft
and having an arm at nearly right angles to the arm of the sleeve and extending
into the path of the arms which project from diagonally-opposite sides of a hub
carried by the driving shaft. The plunger will be tripped at every half revolution of
the driving shaft so as to permit it to move freely down and up through the bath
tank. The object of this arrangement for tripping the plunger twice, is to provide
for successive movements of the photograph plate so as to force it first from behind
the lens tube and second through the bath tank. The first tripping of the bell
crank will release the arm which will have dropped upon it, thus permitting the
plunger to drop to the top of the tank and the second tripping of the plunger, that
is when the bell-crank is moved from beneath the pin which will have dropped upon
it, will permit the plunger to drop downward through the bath tank and expel the
photograph plate. When the photograph plate drops from the bath tank after
being developed it passes into a grooved receiver which consists of two connected
side pieces grooved on their inner sides and this receiver extends downward into a
fixing bath received in a tank. The receiver aligns vertically with the bath tank
and has a slotted drum at the top which is carried by a shaft provided with a
grooved pulley around which passes a cord which connects with an arm of a sleeve
held loosely on the countershaft and another arm on the sleeve extends into the
path of a cam on the driving shaft so that at every revolution of the driving shaft,
the cord will be actuated and the receiver raised into a horizontal position.
Immediately behind the receiver there is a holder which extends downward a little
below the receiver and has a forwardly extending plate which projects beneath the
receiver and supports the photograph plates which are dropped into the latter.
The holder is carried by a shaft which has a rearwardly extending arm on which
there is a counterbalance and when the receiver is tilted upward, the counter-
balance will cause the holder to follow it until the holder reaches a nearly horizontal
position at which point the receiver will continue upward and the inclination will
be so slight that the plate will not slide from it. To deliver the finished picture a
pusher is employed, the same consisting of an arm carried by a shaft journaled in
suitable supports above the fixing tank and in front of the bath tank. This shaft
has an arm on one side on which is a weight which normally throws the pusher arm
forward. Another arm on the shaft and on the lower side is secured to a rod which
extends backward and connects with an arm on a sleeve held loosely on the counter-
shaft and an arm of this sleeve extends into the path of a cam carried by the
driving shaft. Said cam is narrow so that during a greater part of the revolution
of the driving shaft the pusher arm is held forward but at the right time the cam
strikes the arm and throws it down so as to pull back the pusher arm thus bringing
its lower end behind the plate carried by the receiver. When the cam passes the
arm the weight will throw the pusher arm quickly forward and the arm striking

page_text: the photograph plate in the receiver will throw the plate forward upon the tray
and the finished picture may thus be easily reached by the purchaser.
The operation of the machine is as follows:-A person takes his stand in front
of the exposure opening and drops a coin in the slot so that it will release the
driving shaft in the manner described. The operations for taking the picture all
take place during one revolution of the driving shaft. When the shaft starts the
plate fly will be released and will spring upward into a vertical position and will
hold in place the photograph plate which has been left in front of the fly by a
previous operation. At about the same time the shutter will be released and the
plate exposed. At nearly the same instant a charge of developing liquid will be let
into the bulb and the valve which controls the delivery from the bulb will be opened
so as to permit the developing charge to flow into the bath tank and the plate will
be withdrawn by means of the mechanism and the plate dropped into the developing
bath. The plate is allowed to remain momentarily, but soon the valve at the bottom
of the developing bath is thrown backward and the plunger is tripped, the drum
having moved so as to move the cord to permit the plunger to drop and the plunger
dropped downward behind the lens tube and through the bath tank and the plate
therein carried down into the receiver. The bath liquor passes out through the
gutter and the valve is closed so as to prepare the bath tank for another charge.
The drum will also be tripped and the weight or counterbalance will return the cord
which will raise the plunger to its upper position. After the plate has been
immersed in the fixer, the receiver is raised into a horizontal position, the holder
following it through a quarter of its movement, and when the receiver has reached
the horizontal position the pusher arm is tripped and the plate, which is now a
finished picture, is thrown forward upon the tray. The final movement of the
driving shaft will actuate the feeding mechanism of the photograph plate holder and
it will at the same time cause the magnet to pull down and deliver into the chute a
plate which will slide down in front of the fly, ready for the next operation.

Improvements in Coin-operated Photograph Machines.
We PIERRE VAN WYCK WELSH, Inventor, of 887 Third Avenue, Brooklyn
in the County of Kings and WILLIAM FRANCIS FREEMAN, Real Estate Agent, of
The Winthrop, 125th Street & Seventh Avenue, New York, both in the State of
New York, United States of America 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 :-
Our invention relates to improvements in coin operated photograph machines and
the object of our invention is to produce a machine which will be actuated by the
dropping of a coin in a slot, and which will take a perfect picture of any object in

the mechanism shall have very simple, easy and positive movements to the end that
the machine may work perfectly and wear well.
To this end, our invention consists in certain features of construction and
combinations of parts, which will be hereinafter described and pointed out in
the claims.

The main case is provided with a suitable base 5, having a door to enable its
interior to be reached, and extending upward from the corners of the base are rods 6,
between two of which a counterbalance 7 is held, and this counterbalance connects with
a chain 8 which runs over suitable guide pulleys 9 and connects with the movable lens
case 10 which slides vertically above the base 5, the counterbalance enabling it to be
easily moved. The case 10 has an exposure opening 11 in the front side, and a delivery
tray 12 beneath it, on which the finished pictures are thrown. The case is also provided
with a coin chute 13 in which the coin is deposited, and this delivers, as shown in
Figure 7, upon the coin plate 14 on the free end of a lever 15, which lever is
secured to a shaft 16, journaled in suitable supports, and the shaft has a counter-
balancing weight 17 on one side, and on the other a projecting arm 18, connecting

page_text: by a rod 19 with a tilting lever 20, which is pivoted near the centre, and which at
its free end carries a tripping arm 21 adapted to extend into the path of a fan 22,
which is driven by the clockwork 23.
The coin chute and the clockwork mechanism is not shown in detail, as the
construction above described is similar to that shown in Letters Patent of the
United States, No. 465,740, issued December 22, 1891.
The clockwork 23 drives the main shaft 24, which extends horizontally through
the back portion of the machine, as shown in Figure 3, and this shaft carries
the cams which effect the various operations of the several parts of the machine, as
hereinafter described. On one end of the driving shaft 24 is a disk 25, having a
notch 26 in one side, and this arrangement is also similar to that shown in the
former Patent referred to above. It was found, however, in working the mechanism
described in the former Patent, that when the tripping arm on the lever 15 dropped
from the slot 26, it would sometimes return quickly enough to enter the slot before
the revolution of the disk, and consequently the machine would not work. To
obviate this difficulty, an arm 26 is secured to the lever 15, and has its upper
end 27 bent at a right angle so as to enter the slot 26. The slot 26 is partially
covered by a flat spring 28, which is secured to the circumference of the disk 25,
and the free end of which lies loosely over the slot.
It will be seen then that when the lever 15 is depressed by the dropping of the
coin upon its free end, the bent end 27 of the arm 26ª will be carried below the
spring 28, and the spring immediately flies back to place, so that if the lever should
return quickly, the bent end 27 of the arm would strike the spring and be
prevented from entering the slot in the disk. When the arm is removed from
the disk, the clockwork starts so that the machine is operated, and as the disk
revolves, the bent end 27 of the arm will pass between the spring 28 and the
face of the disk, so as to again enter the slot when the latter is brought into
position to register with the arm.
The machine is provided with a lens tube 29 of the common form, which is
arranged opposite the exposure opening 11, and at the front end of the lens tube
is a frame 30 in which the shutter 31 is held to slide (see Figures 6 and 23) and a
rack on the shutter engages a gear wheel 32, carried by a shaft 33 which is
journaled in suitable hangers 34, this shaft having also a drum 35 thereon to
which is secured a cord or cable 36, and the latter extends backward and downward
in the machine and is secured to an arm 37 of a sleeve 38, which is journaled
loosely on a countershaft 39, arranged parallel with the shaft 24, as shown in
Figure 6, and the sleeve has a projecting arm 40, adapted to engage with a cam 41,
carried by the driving shaft 24.
It will thus be seen that at the right time the cam 41 will tilt the arms 40 and 37,
thus pulling upon the cord 36, revolving the shaft 33 and gear wheel 32, and
raising the shutter. As soon as the cam 41 passes the arm 40, the shatter will
drop back to place of its own weight.
At the inner end of the lens tube 29, is a swinging fly 42, which is adapted to
swing up parallel with the opening of the lens tube in the frame 42" (see Figure 11)
and the fly 42 is normally pressed into a vertical position by a spring 44, which
is secured to an arm on the fly and to one side of the chute 43 in which the
fly swings, as best shown in Figure 21. The chute 43 extends downward to the
inner end of the lens tube, and through it the photograph plates are dropped as
described below. The fly 42 has secured to its back side a rod 45, which connects
with an arm 46 upon a sleeve 47, which is journaled loosely on the shaft 39,
and an arm 48 of the sleeve extends into the path of a cam 49 on the driving shaft 24.
When a plate is dropped in front of the fly 42, the cam 49 will be in the position
shown in Figure 21, and as soon as the driving shaft 24 starts, the cam will move
and the side of the cam which is cut away will be brought opposite the arın 48,
thus releasing the arm and permitting the spring 44 to swing the fly 42 into a
vertical position so as to adjust the plate. The upper end of the plate chute 43
registers with an opening 52 in the base 50 of the feeding mechanism, which base

page_text: is held upon the partition 51 in the main case. The plate holder is carried upon
this base 50, and consists of two similar and semi-rectangular sides 53, an open
space being left between them, as shown in Figure 12, and the plates 54 are held
one above another within the holder, and between the two sides 53. Extending
around the holder, and at right angles to each other, are shafts 55, which are geared
together by bevel gear wheels 56, so that all will turn in unison, and the shafts are
journaled in supports 57. The shafts 55 also carry gear wheels 58, which engage
sliding racks 59 held at right angles to the shaft and adapted to slide on the base 50.
The racks 59 have projecting inner ends 60, which are adapted to extend beneath
the plates 54, and the shafts and racks are arranged so that the racks will be
moved at every revolution of the shaft, but the racks on the sides and ends of the
holder will move alternately, that is to say, when the end projections 60 are
beneath the plates 54, as shown in Figure 11, the side projections will be withdrawn
and vice versa. This arrangement enables the plates to be dropped one by one, as
when one set of projections is withdrawn the other will be moved in.
To enable this arrangement to be successfully carried out, the plates 54 are
provided on the sides and ends with notches 61, the side notches being produced in
one plate and the end notches in the next, and the notches are adapted to slip over
the projections 60. The plates 54 are of the usual kind, such as are used in taking
tintypes.
One of the shafts 55 is provided with a square end 62, which is adapted to receive
a crank 63, as shown in Figure 4, and the crank connects by means of a pitman 64
with a gear wheel 65 on the counter-shaft 66, which is held above and parallel
with the driving shaft 24, and the gear wheel 65 engages a pinion 67 on the driving
shaft 24. It will thus be seen that every revolution of the driving shaft will turn
the shaft 55 so as to deposit a plate in the chute 43.
In order that the sensitive plates may be placed in the holder without undue
exposure, a flexible hood 68 is provided at one side of the holder, as shown in
Figures 4 and 19, the hood surrounding an opening 69 in the side of the case, and
a package of plates may be thrust in through the hood and adjusted in the machine
without exposing them to the light.
To prevent all possibility of any of the plates sticking in the plate holder, the
mechanism shown in detail in Figure 5 and also in Figures 3 and 4 is used. A
magnet 69 preferably a common horseshoe magnet, is arranged to swing beneath
and against the plates 54 in the plate holder, the magnet being secured to one end
of a rod 69" and the other end of this rod is secured to an arm 69 on a shaft 69
which is held in suitable supports below and at one side of the plate holder, and an
outwardly extending crank arm 69 on this shaft connects with a depending and com-
paratively stiff spiral spring 69', the lower end of which is pivoted to another
arm 69 carried by a shaft 69 to which is also secured an arm 69' which extends
into the path of a cam 69 on the driving shaft 24.
The magnet 69 swings in a slot in the feed chute 43 and it is normally held
upward against the bottom plate in the plate holder, as the arm 69' will ride on the
cam 691 and be swung so as to pull down the arm 69, the spring 69' and arm 69°, thus
swinging the rod 69" and magnet 69" upward into position to hold the magnet against
the plates, but after a picture has been taken, the revolution of the shaft 24 brings
the cutaway portion 69% of the cam 69' opposite the arm 69' and the magnet 69ª
drops into the position shown in Figures 4 and 5 and takes with it a plate which is
caught by the feed chute and delivered behind the fly 42.
The spring 69 connecting the upper and lower portions of the magnet operating
mechanism, enables the magnet to strike yieldingly upon the plates so that no harm
ensues, and to prevent the magnet from being thrown up too far, a post 69m is
secured to a support and arranged in the path of the rod 69.
Beneath the chute 43 and the adjusting fly 42, is a swinging arm 70, which is
pivoted at its lower end in lugs 71 and is normally pressed into a vertical position
by a spring 72, as shown in Figures 11 and 25, and the upper end of this arm is
provided with a plate 73 which is adapted to pass beneath the fly 42 and close the

page_text: top of the developing bath tank 74, as shown in Figure 11. The plate 73 will thus
support a photograph plate 54, and when the arm 70 is pulled out, it carries the
plate 73 with it, and gives free passage for the plate 54 to pass on into the bath
tank 74 as hereafter described. To effect this movement, the back of the arm 70
connects by a rod 75 with an arm 76 on a sleeve 77 which is journaled loosely on
the shaft 39, and the sleeve has a projecting arm 78, extending into the path of
a cam arm 79 on the driving shaft 24, this arrangement being shown in Figure 24,
and when the arm 78 is struck, the arm 76 will be tilted and the arm 70 pulled
back, to be returned to position by the spring 72.
The lower end of the bath tank 74 is cut off diagonally, as shown at 74ª in
Figure 11, and this end is adapted to be closed by a valve 80, to prevent the
developing liquid from running out, and the valve 80 has on its inner side a
packing 81, adapted to fit snugly upon the lower end of the bath tank. The
valve 80 has side pieces 82 adapted to close over the sides of the tank, and these
side pieces are prolonged upward and pivoted to a shaft S3, which is journaled in
suitable supports at the back of the tank.
The
Pivoted on opposite sides of the valve 80 are the upwardly and forwardly-
extending arms 85, which are pivotally secured to cranks 86 on a shaft 87, which
has a weight 84 to counterbalance the valve and which is journaled in hangers 88
in front of the bath tank 74, and a crank 89 on the shaft 87, connects with a rod 90
which extends backward and is pivoted to an arm 91, on the sleeve 92 which is
carried on the shaft 39, as shown in Figure 22, and has an outwardly-extending
arm 93, which projects into the path of a cam 94 on the driving shaft 24.
cam 94 is nearly semi-circular in form, and consequently will bear for rather more
than half the time on the arm 93 and thus hold the valve 80 in position, but at
one end of the plane bearing surface of the cam is a notch 95, which permits the
valve to slacken slightly when the arm 93 drops into it, and half of the cam is cut
away at 96, so as to release the arm 93 and permit the valve 80 to drop down from
the bath tank so that the liquid therein may escape.
When the arm 93 drops
into the notch 95 the valve 80 drops slightly and deflects the liquid into a
gutter 142 described hereinafter, and thus prevents the liquid from dropping into
the fixer.
It is obvious that the tank 74 must be kept tightly closed while the picture is
being developed, and to obviate the necessity of a very nice adjustment of the levers
the following connection between the crank 89 and the shaft 87 is employed. The
crank 89 has on one side a hub 97, (see Figure 20,) which is loosely mounted on
the shaft 87, and on this hub is a spiral spring 98, one end of which is fixed to the
crank and the other end to the shaft, and consequently this yielding connection will
enable the valve to be jammed tightly to place with no fear of breaking anything,
or of the leakage of the valve.
The developing liquid is carried in a removable tank 99, which is held in a
receptacle 100 in the upper portion of the machine, this receptacle being carried
by brackets 101 secured to a partition in the case 10. The developing tank 99 has
an inlet 102 through which it may be filled, and an outlet 103 through which it
may be emptied, and these openings are closed by stoppers 104, as shown in
Figure 9. A tube 105 leads from the lower portion of the tank, this tube having
its upper end enveloped by a packing 106, and the tube delivers into a bulb 107,
which holds a charge for the bath tank 74, and which has an outlet pipe 108 on the
under side. An air pipe 109 opens from the upper portion of the bulb 107, and
extends upward through suitable supports 110, and the object of this is to enable
the bulb to be quickly filled and emptied. The outlet tube 105 is closed by a
weighted conoidal valve 112, and this connects by a cord or rod 113 with a
valve 114, which is adapted to close the air inlet 111 of the tank, and consequently
the two valves may be simultaneously operated.
The valve 114 connects by a rod 115 with one end of a tilting lever 116, which
is pivoted in a support 117, and the opposite end of the lever connects by a rod 118
with a tilting lever 119, this being centrally pivoted in a hanger 120, and the free
B

page_text: end of the lever 119 extends into the path of an arm 121 on the sleeve 122, which
is secured to the shaft 24, and the sleeve has a projecting arm 123 extending into
the path of the arm 124 of the sleeve 125, which is held loosely upon the counter-
shaft 39, and has a projecting arm 126 which connects by a rod 127 with one
arm 128 of a bell crank 129, which is pivoted on a stud 130 beneath the tank 99,
and which has its upper arm 131 connected by a rod 132 with the yoke 133 of the
parallel rods 134, which are held to move horizontally beneath the tank 99 and in
the supports 135, the rods being normally pressed forward by a weight 136 on the
bell crank, and the rods have at their front ends a cross-head 137, an arm on the
lower end of which carries a valve 138 which enters and closes the tube 108 leading
from the bulb 107. The tension of the weight 136 will therefore normally hold the
valve closed so as to stop the tube.
Beneath the outlet tube 108 is a funnel 139, supported in a hanger 140, and
leading from the funnel is a tube 141 which delivers into the top of the bath
tank 74. It will be seen that at every revolution of the driving shaft 24, the
valves 114 and 112 will be actuated so as to charge the bulb 107, and the valve 138
will be withdrawn so as to carry the developing charge to the bath tank 74. When
the bath tank is emptied, the liquid flows into a small gutter 142, which is arranged
beneath and a little to one side of the bath tank, and the shape of the tank and
the valve beneath it will serve to deflect the liquid into the gutter. From the
gutter the exhausted liquid is conducted through a tube 143, and delivered into a
waste tank 144, which is held in the lower part of the case.
To insure the quick movement of the photograph plate through the tank 74 after
the picture has been developed, a plunger 145 is used, which is held normally above
the back of the lens, as shown in Figure 11, and moves downward through the
chute 43, and this plunger has on one side a pin 146 held to move in a guide 146°,
see Figure 3, and the plunger is held normally upward by a cord 147, which moves
over a pulley 148 held in the hanger 149, as shown in Figure 3, and the cable or
cord is secured to a weight 150, which is held to slide in a box 151. Instead of
the cord 147, a wire may be used, and is preferably employed at the part where the
arm 154 runs upon it.
The plunger has on one side a laterally-extending stud 152, (see Figure 4,)
which is adapted to rest on a tripping lever as hereinafter described, and the
plunger has also a laterally-extending perforated arm 154, which extends into the
path of a stop 153 on the cord or cable 147, and consequently the stop and arm
will move up and down together, the stop serving to hold the plunger in a raised
position.
The cable 147 extends downward and backward through the case over guide
pulleys 155, 156 and 157, and the lower end of the cable is fixed to a drum 168,
which turns loosely on a shaft 159 journaled in a suitable supporting frame in the
back part of the case and at right angles to the driving shaft 24, the shaft 159
having at its inner end a bevel pinion 160, which meshes with a pinion 161 on the
driving shaft, as shown in Figure 6. At one side of the drum 158 is a collar 162,
which is fixed to the shaft 159, and projecting from one side of the collar and
parallel with the sides of the drum, is an arm 163 to which is pivoted a lever 16+,
and the latter is pressed by a spring 165 against the side of the drum 158, so as to
engage a stud 166 on the drum, and consequently when the collar is turned, the
drum will be carrel with it.
The lever 164 is beveled or inclined on the side next the drum, as shown in
Figure 17, and extending into the path of the lever is an oppositely-inclined
arm 167, which is fixed to a suitable support, and when the arm comes in contact
with the lever, the lever will be forced away from the drum, thus permitting it to
free itself from the stud 166, and this will provide against the drum's making more
than one revolution at a time, and will also permit the counterbalance or weight 150
to return the drum and plunger to their normal positions.
To further guard against the turning of the drum 158 more than a revolution,
and to permit it to oscillate slightly at the end of its stroke, a lever 168 is pivoted

page_text: loosely on the drum and held to play loosely on studs 169, as shown in Figure 16,
and the free end of the lever projects outward so as to engage a fixed stud 170,
held to an adjacent fixed portion of the case. It will thus be seen that the lever 168
will first strike the stud on the under side and then on the upper, and the movement
of the lever will permit the drum to turn a complete revolution.
The plunger 145 is held upward by a bell crank 172, one arm of which engages
the pin 152 on the plunger, (as shown in Figure 3,) and the bell crank has its
lower arm held to swing upward against the stud 173, and is normally held against
the stud by a spiral spring 174. A rod 175 leads downward from the bell crank
and connects with another bell crank 176, which is pivoted to the frame 42ª, as
shown in Figure 25, and the lower arm of this bell crank connects by a rod 177
with an arm 178 of a sleeve 179 held loosely to the shaft 39, and having an arm 180
at nearly right angles to the arm 178, the arm 180 extending into the path of the
arms 181 which project from diagonally opposite sides of a hub 182 carried by the
driving shaft 24.
It will thus be seen that the plunger will be tripped at every half revolution of the
driving shaft, so as to permit it to move freely down and up through the bath tank.
The object of this arrangement for tripping the plunger twice, is to provide for
successive movements of the photograph plate so as to force it first from behind
the lens tube, and second through the bath tank 74. The first tripping of the bell
crank 172 will release the arm 154, which will have dropped upon it, thus
permitting the plunger to drop to the top of the tank 74, and the second tripping of
the plunger, that is, when the bell crank is moved from beneath the pin 152 which
will have dropped upon it, will permit the plunger to drop downward through the
bath tank and expel the photograph plate.
When the photograph plate drops from the bath tank after being developed it
passes into a grooved receiver 183, which consists of two connected side pieces
grooved on their inner sides, and this receiver extends downward into a fixing bath
carried in the tank 184. No means is provided for changing this bath as it will
last for a comparatively long time, and when exhausted it may be easily renewed.
The receiver aligns vertically with the bath tank and has a slotted drum 185 at the
top, which is carried by a shaft 186. The shaft 186 has a grooved pulley 189
thereon, carrying a cable 190, which connects with an arm 191 of a sleeve 192, held
loosely on the countershaft 39, and another arm 193 on the sleeve extends into the
path of a cam 194 on the driving shaft 24, so that at every revolution of the driving
shaft, the cable 190 will be actuated and the receiver 183 raised into a horizontal
position.
Immediately behind the receiver 183 is a holder 195, which is carried by a
shaft 196, (as shown in Figure 11,) and the holder extends downward a little below
the receiver, and has a forwardly-extending plate 197, which projects beneath the
receiver and supports the photograph plates which are dropped into the latter.
The shaft 196 has a rearwardly extending arm 198, on which is a counter-
balance 199, and when the receiver is tilted upward, the counterbalance will cause
the holder to follow it until the holder reaches a nearly horizontal position, at
which point the receiver will continue upward and the inclination will be so slight
that the plate will not slide from it. The point at which the receiver and holder
part may be easily adjusted by means of the counterbalance 199.
A pusher arın 200, is carried by a shaft 201, which is journaled in suitable
supports above the fixing tank and in front of the bath tank, and this shaft 201 has
an arm 202 on one side on which is a weight 203 which normally throws the pusher
arm forward, as shown in Figure 26. Another arm on the shaft and on the lower
side is secured to a rod 204, which extends backward and connects with an arm 205
on a sleeve 206, held loosely on the countershaft 39, and an arm 207 of this sleeve
extends into the path of a cam 208 carried by the driving shaft 24. The cam 208
is narrow, so that during a greater part of the revolution of the driving shaft the
pusher arm 200 is held forward, but at the right time the cam strikes the arm 207,
and throws it down so as to pull back the arm 205 and the pusher arm 200, thus

page_text: bringing the lower end of the arm 200 behind the plate carried by the receiver 183,
and at this time the receiver with the plate will be in the position shown by dotted
lines in Figure 27. When the cam 208 passes the arm 207, the weight 203 will
throw the pusher arm 200 quickly forward, and the arm striking the photograph
plate in the receiver, will throw the plate forward upon the tray 12, and the
finished picture may thus be easily reached by the purchaser.
The operation of the machine will probably be understood from the foregoing
description, but the different operations take place in the following order and
manner. A person takes his stand in front of the exposure opening 11, and drops
his coin in the slot 13, so that it will pull down the lever 15, and release the driving
shaft 24 in the manner described. The operations for taking the picture all take
place during one revolution of the driving shaft. When the shaft starts, the
cam 49 will be in the position shown in Figure 21, and will immediately release the
arm 48, and the plate fly 42 will spring upward into a vertical position and will
hold in place the photograph plate which has been left in front of the fly by a
previous operation. At about the same time the cam 41 will actuate the arms 40
and 37 and the gear wheel 32, thus releasing the shutter 31, and exposing the plate.
At nearly the same instant, too, the lever 119 will be tilted by its connected cam
mechanism, shown in Figure 9, and a charge of developing liquid will be let into
the bulb 107. The arm 126 will by this time have tilted the bell-crank 130, and
withdrawn the valve 138, so as to permit the developing charge to flow into the
bath tank 74, and the plate 73 will be withdrawn by means of the mechanism
connected with the cam 79, (as shown in Figure 21), and passed into the developing
bath. The plate is allowed to remain momentarily, but soon the rod 90 is actuated
by means of its connection with the cam 94, and the valve 80 thrown backward into
the position shown in Figure 11, and the plunger 145 is tripped, the drum 158
having moved so as to move the cable 147 to permit the plunger to drop, and the
plunger dropped downward behind the lens tube and through the bath tank, and
the plate therein carried down into the receiver 183. The bath liquor passes out
through the gutter 142 in the manner described, and the continued movement of
the cam 94 again closes the valve 80 so as to prepare the bath tank for another
charge. The drum 158 will also be tripped in the manner described and the weight
or counterbalance 150 will return the cable 147 which will raise the plunger 145 to
its upper position.
After the plate has been immersed in the fixer, the cable 190 is actuated by
means of its connection with the cam 194 and the receiver 183 raised into a
horizontal position, the holder 195 following it through a quarter of its movement
in the manner described, and when the receiver has reached the horizontal position
the pusher arm 200 is tripped by the cam 208, and the plate which is now a finished
picture is thrown forward upon the tray 12. The final movement of the driving
shaft will actuate the pitman 64 and the feeding mechanism of the photograph plate
holder 53, and it will at the same time cause the cam 691 to release the arm 69¹ and
the magnet 69, so that the latter will pull down and deliver into the chute 43 a
plate 54 which will slide down in front of the fly 42 ready for the next operation.
