Coin Controlled Apparatus.
I, WILLIAM REEVES, of 124, Dwight Street, in the City of New Haven, in the
County of New Haven and State of Connecticut, in the United States of America,
Photographer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:
-
This invention relates to coin-controlled apparatus for the exhibition of trans-
parencies, the light for which is presented on the opposite side of the view or slide
from the eyes of the spectator; the transparencies being mounted on an endless
rotary band or series of sections, operated by clock-mechanism under control of a
coin deposited in the usual slot or chute.
The invention consists in certain improvements in the mechanism for rotating
and adjusting the band, registering the deposit of the coin, making and breaking
connection of the electric light used to exhibit the transparencies, and other features
fully described and claimed hereafter.
The invention is illustrated by the accompanying drawings, in which
Fig. 1 is a perspective view of the casing of the machine showing the front and
one side.

In all figures similar letters of reference represent like parts.
In the drawings, the casing containing the apparatus is shown divided into two
parts. 1 and 2, the upper part, 1, consisting of a top, 3, bottom, 4. frout 5, back 6,
and sides 7 and 8. The top 3 is hinged to the upper edge of the side 7, so that it
may be swung back to expose the interior of the casing. In the side 7 is an open-
ing or glazed window 9, through which light is admitted to the interior of the
casing.
An incandescent light 10, the electric connections of which will be more fully
described hereafter is within the window 9. The opposite side 8 has a hinged
door 11 for admission to the interior of the casing, while in the back 6 is a circular
opening through which may pass conductors 12 for the electric light 10. In the
bottom of the upper portion 1 of the casing are two openings; a circular one 13,

page_text: and a slot 14, which correspond to similar openings 15 and 16 in the top of the
lower portion 2 of the casing. The lower portion 2 of the casing is also provided
with a drawer 17 with the usual handles 18 in front. The drawer 17 is adapted
to hold a battery from which electric wiring may pass through openings 15 and 13
into the interior of the upper portion 1 of the casing, and a money-box located 5
beneath the slot 16 for the reception of the coin. The front 5 of the upper portion 1
of the casing is provided with an observation glass or stereoscope 19 with the usual
lenses 20 through which the transparencies may be seen. To one side of the
stereoscope 19 is a slot 21 for the admission of the coin and on the other side an
electric button 22. In the lower part of the front 5 is an opening 233 to the coin 1
register (described hereafter) and a hinged plate 24 (for the programme or other
notice) normally held by a spring 24" against the front, over the opening 23.
Within the upper portion 1 of the casing is a vertical plate 25 of wood or other
material parallel to the front 5. Two skeleton supports 26 and 27 are mounted
on the bottom 4, and secured to the front plate 25 by binding wires or other means 1
and to each other by three transverse rods 28 and 29. On the frame thus formed
are loosely mounted on a revolving shaft 30 journaled in the supports 26 and 27
at 31 near the bottom thereof, two hexagonal wheels 32, secured together by the
rods 33. Rigidly mounted on the shaft 30 are two arms 34, which are adapted to
be adjustably connected to the wheels 32 by means of screws and nuts 35, which 2
may slide in concentric slots 36 in the wheels 32. By this means any rotary move-
ment of the shaft 30 is communicated to the wheels 2, while they may be turned
lightly on the shaft separately when desired.
In the upper part of the supports 26 and 27 are vertical - 87 though which
project hearings 39 for a shaft 40, on which a rigidly mon fed two wheels 112
similar to the wheels 32. The bearings 39 being adjustable in a vertical line, the
shaft 40 may be raised and lowered so that the distance between the upper pair
of wheels 41 and lower pair 32 may be varied at will.
Over the wheels 32 and 41 passes an endless band or belt 43 composed of flat
rectangular metallic frames or sections which are open and connerted to each other 3
by rings see Figure 5. The horizontal portion of the sections is provided with
flanges (see Figure 6) bent toward each other to be substantially parallel to the
section itself, so that guides are formed extending transversely to the band or belt 433
to receive the transparencies. The wheels 32 and 41 are provided with peripheral
flanges 42 on the outer sides to guide the band or belt 43 in its movement. The 3
front lap of the band 43 passes at the rear of a rectangular opening 44 in the
vertical plate 25 opposite the stereoscope 19, and between the two flaps on the
rods 28 is arranged diagonally a reflector 45 to deflect the light from window 9
upon the transparency directly in the rear of the opening 44.
The means for rotating the wheels 32 and 41 consist of two clock mechanisms, 4
the upper of which, 46, is adjustably mounted on the upper end of one of the
supports 26, and meshes with a pinion or gear 47 on the shaft 40. The tendency
of this mechanism (which will not be described in detail) is to constantly rotate the
shaft 40 and wheels 41 mounted thereon. A similar but more powerful clock
mechanism 48 is mounted on the lower part of the support 26 to mesh with a 4
similar pinion or gear 49 on the lower shaft 30, which in turn rotates the wheels 32
by means of the arms 34.
b
The lower clock mechanism 48 consists of two springs a, and a series of
gears b, c, d, and e, the gear & meshing with the pinion 49. On the gear e are
two or more stop pins f projecting laterally from one side thereof, and on the gear d 5
is a cam g with an abrupt shoulder h. Two shafts, i and k, are journaled in
the support 50 of the clock mechanism; the shaft i carrying a crooked catch!
normally pressed downward by a torsional spring m surrounding the shaft i and
extending to and abutting against a rigid shaft n on the supports 50. On the
shaft is also mounted a lever o with a right-angled extension adapted to rest 5
on the cam g of the gear d. Shaft & carries a stop or check q adapted to engage
the stop pins on the gear e, and a lever r which bears on the under side of the

page_text: lever o. A torsional springs, surrounding the shaft k and abutting against shaft n
tends to force the check q and lever r downward. An operating-arm or trigger t
is also rigidly secured to the shaft k and extends upward so that its upper end may
be engaged by lateral trip pins G on a gear C in a secondary train of gearing form-
ing a time-regulating clock-mechanism 51. This regulating mechanism 51 consists
of two springs A and a train of gears B, C, D, E, and F, the gear C having the
lateral trip pins G, and the gear I carrying the fly H.
The revolution of the band 43 is therefore affected in the following manner.
The upper clock mechanism 46 is constantly tending to rotate shaft 40 and
wheels 41, while the lower mechanism 48 rotates the shaft 30 and wheels 32, when
the train of gears is free to operate, which is only possible when the catch / is not
engaged with a stop pin f on the gear e (which revolves in the direction of the
arrow, Fig. 7). Catch being rigidly secured to shaft i, is raised by means of
the throw-off lever r forcing up lever o, which is also rigidly secured to the shaft i.
The throw-off lever r is forced up when the shaft (to which it is secured) is
partially rotated, which is effected by trigger t being forced in the direction
of the arrow, Fig. 7, by the trip-pins G on the gear C of mechanism 51. On every
third of a revolution (the number of trip-pins G being shown as three) of the gear C,
the trigger t is forced toward the left (Fig. 7), and the catch 1, released from
engagement with the stop-pins f. But the same movement of trigger which
releases catch, raises check 9 so that it will abut against one of the stop-pins f of
the gear e when the gear e is revolved far enough for the stop-pin f to clear the
catch 1. Gear e is thereby allowed but a slight revolving movement until the trip-
pin G, being rotated on the gear releases the end of trigger t, in which case
trigger t is forced toward the right (Fig. 7) by torsional spring s slightly rotating
shaft and depressing check until it clears the stop-pin f on geat c, permitting
gear e to revolve, and the whole train of gears d, c, b, and a to likewise revolve and
rotate pinion 49 (meshing with gear b) thereby setting in motion wheels 32 and
rotating the band 43 so that the next transparency is moved to a place in front of
the opening and stereoscope 19. When check y is depressed, lever o and catch
are forced downward by torsional spring m. But catch can only be lowered
sufficiently to engage a stop-pin f on gear e and stop the movement of the gear
when the end of lever o passes over the shoulder h on cam g on gear d. By means
of this cam gand the position of the stop-pins f the length of movement of the
revolution of the band 43 is determined, while the position of the trip-pins G on
gear C regulates the length of time the band 43 is at rest.
A rod I is connected with the throw-off lever to draw the latter up and set the
clock mechanism 48 in motion irrespective of the regulating mechanism 51. The
rod I may be suitably connected to other rods (such as K, Fig. 5) to bring the
operation of the clock mechanism 48 and the consequent revolution of the band
within reach on opening the casing 1 at the top 3.
The clock mechanism 48 and consequently the band 43, being limited in its
operation by mechanism 51, the whole apparatus may be started or stopped by
releasing or checking mechanism 51. This is accomplished by the coin operated
device, which consists in the first place of two coin chutes, one, 52, inclined down-
ward from, the coin slot 21 to a point over the upper end of the other, 53, which is
vertical and is slotted in its sides (as shown in Fig. 5). In the inclined chute 52
is a slot on the under of the two inclined sides of said chute of such width as to
prevent the passage of smaller coins which would drop through said slot and out of
the chute, while the lower end of the vertical chute 53 is directly over the slot 14
in the bottom 4 of the upper portion of the casing through which the coin may pass
into the money box in the lower portion 2 of the casing. Extending through the
lateral slots of the chute 53 are the ends of rod 65 and lever 54, connected with the
registering mechanism (described hereafter), and the operating mechanism, re-
pectively. The coin-controlled lever 54 is pivoted on the vertical plate 25 to
wing in a vertical plane and has at its other end a horizontal hook 55. An L-shaped
operating lever 56 is pivoted to the rear of the plate 25, its horizontal arm terminat-

page_text: ing in a hook 57, which is adapted to engage the fly-wheel H of the mechanism ól,
and when so engaged to check the mechanism. At the extremity of the vertical
portion of the lever 56 is a loop 58 projecting through a slot 59 in vertical
plate 25, through which extends the end of the coin-controlled lever 54. The loop 58
is so inclined that when the end of lever 54 is depressed it will force the
lower end of lever 56 toward the rear (Fig. 5), and raise the horizontal portion to
disengage the hook 57 from the fly wheel H, allowing the mechanism 51 free
movement.
The hook 57 is held from engagement with the fly-wheel H as long as the end
of lever 54 is depressed, but immediately that the end of lever 54 is free to rise,
a weight 60 on the horizontal portion of the lever 56 forces the hook downward into
engagement with the fly-wheel H which checks the movement of mechanism 51.
The means for holding the end of lever 54 downward so that the hook 57 is
clear of the fly-wheel H consists of a U-shaped lever 61 pivoted to the front of
vertical plate 25 to swing in a horizontal plane. One end of lever G1 extends
toward coin-controlled lever 54 in front of the plate 25 and has pivoted at its end
an L-shaped trip 62, to swing in a vertical plane, which when in its normal
position extends above and slightly beyond the hook 55, of lever 54, as shown in
elevation Figure 4. When the end of lever 54, which extends through the loop 58
and chute 53, is depressed by the fall of a coin, the hook end 55 of said lever 54,
is forced upward to engage with the L-shaped end of trip 62, and to swing the
trip 62 on its pivot, so that the outer face of hook 55 passes the elbow of the trip 62;
when it will engage the hook end at the trip 62, and be held in engagement thereby,
for the distance between the pivots of the trin 62 and lever 35 is shorter than the
combined lengths of the portions of trip 62 and lever 54 between these pivot-.
Upon the revolution of the band 43, a wire cam 64, is adapted to engage with
the end of the lever 61, which extends to the rear of plate 25 and forces the end of
said lever outward, swinging the lever in a horizontal plane, so that the trip 62
is swung inward horizontally toward plate 25, until said trip is free of the
hook 55, (Figure 10) when the end of lever 54 is dropped into its normal position
by a weight 63 attached thereto, and the lever 61 swung back to its normal position
by means of a wire spring, one end of which may be secured to the front of plate 25,
and the other free end bear against the end of said lever (as shown in Figure 4).
When the hook 55 is released from the trip 62, the end of the trip drops down
to its original position by its own weight.
The disengagement of the hook 55, of lever 54, from the trip 62, and the return
to its normal position, by means of the weight 63, raises the other end of said
lever 54, which in turn permits the lever 56, to swing on its pivot and the hook 57
to engage with fly-wheel H, to stop mechanism 51, so that the further movement
of the band 43, is stopped.
Rod 65, which, as stated above, extends into the chute 53, is rigidly connected to
a sleeve GG loosely mounted on a shaft 67.
Also secured to this sleeve G6 is a disc 68 carrying a pawl 69 and spring 70, the
former being adapted to engage with a ratchet wheel 71, rigidly secured to shaft 67.
A second ratchet wheel 72 also secured to shaft 67 is adapted to be engaged by a
spring pressed pawl 73 on the frame 74, which supports the shaft 67.
A series of gears 75 rotated by the movement of the sleeve GG through the pawls
and ratchets are provided with markers 76 to register on the four faces of a dial,
in similar manner to a meter, the number of movements of the rod G5. The other
end of rod 65 has a depending arm 78, which extends through the plate 25 and has
its lower extremity slightly curved as shown in Figs. 8 and 9. Laterally projecting
lugs 79 on the band 43 are adapted, (upon the movement of the band) to engage
with the depending end 78 and force it to one side, which turns the sleeve 66 and
restores rod 65 to its normal position in chute 53.
When the rod 65 is depressed by a coin, the sleeve is rotated sufficiently to allow
the pawl 69 to engage the next succeeding tooth of the ratchet wheel 71. When the
end 78 of the rod is engaged by the lugs 79 on the band 43 the sleeve 66 is rotated

page_text: slightly in the opposite direction, and by means of pawl 69 and ratchet 71 the shaft 67
is rotated sufficiently to permit pawl 73 to engage with the next succeeding tooth
of ratchet wheel 72 to prevent the reverse movement of shaft 67 when sleeve 66 is
again turned in the opposite direction by rod 65. This slight movement of shaft 67
sets the gears 75 in motion until the movement is properly registered. By this
means the fall of the coin in chute 53 starts the movement of sleeve GG and the
rotation of the band 43 (by means of the mechanisms set in motion by lever 54)
completes the movement of sleeve 66 so that the coin is registered.
The connection of electric light 10 with the battery in the drawer 17 in the lower
portion 2 of the casing, is made and broken by lever 54 as follows. The wires 81
from the battery extend upward from the opening 13 in the bottom, or, in case
power is received from outside instead of from a battery, the conductors 12 are
secured to terminals or binding posts 80 on the vertical plate 25. From thence
the wires extend downward, one wire 82 passing to the light 10, while the other, 83,
extends to the pivot of the U-shaped lever 61. Another wire 85 extends from the
pivot of coin-controlled lever 54 to the light 10. The connection between wires 83
and 85 and the completion of the circuit is effected when the hook 55 and trip 62
are engaged with each other, which is the case while the band is being rotated, as
shown. Wires 86 and 87 extend from the pivots of levers 61 and 54 to a switch 89
which is operated by the push-button 22 in the front 5 of the casing. By means
of the push button 22 and switch 89 the electric light may be used to light the
picture which is in the rear of the stereoscope when the band 43 is at rest.
A toothed wheel 90 is rigidly mounted on the shaft 330, and is engaged by a
dog 91 on one of the supports 27 to prevent the backward movement of the
wheels 32, and consequently of the band 43.
In operation the coin is dropped into the slot 21 of the casing and chute 52 from
which it passes into the vertical chute 53 and drops into the money box in the
bottom of the casing. In its passage through the chute 53 the coin first comes in
contact with the end of rod 65, which extends into said chute 53, and depresses said
rod, which rotates sleeve 66, sufficiently to allow the pawl 69 to engage the next
succeeding tooth of the ratchet wheel 71. The further downward passage of the
coin in the chute 53, depresses the end of lever 54, which in turn forces the end of
lever 56, toward the rear and raises the horizontal portion to disengage the hook 57,
from the fly-wheel H, allowing the mechanism 51 and 48 free movement, for the
rotation of the band, while at the same time the other end of lever 55 engages with
trip 62 where it is held in its position and completes the electric light circuit.
Upon the revolution of the hand 43, lug 79 on the band is adapted to engage with
the depending arm 78 and force it to one side, which turns the sleeve 66 and
registers the coin, at the same time restoring rod 65 to its normal position in the
chute, when the device is ready to be operated again. I'pon the complete rotation
of the band 43, the can 64 on said band engages one end of the
U shaped lever 61, which is thereby swung onl its pivot, thus forcing
the trip 62 from engagement with the hook end 55 of lever 54, (thus
breaking the light connection) when the weight 63 attached thereto causes
the other end of said lever to swing upward, which in turn permits lever 56 to
swing on its pivot and the hook. 57 to engage with the fly wheel H to stop
mechanism 51 so that the further movement of the band is stopped.
It will be understood that the details may be varied without departing from the
spirit of the invention.
