ร
In the drawings, with special reference now to Fig. 1, a, is a case or housing of
any suitable size and configuration comprising a base a', end plates a² and curved
side and top plates a³. a', is an opening protected by a glass cover formed in the
top plate for a purpose to be hereinafter described. b, is a shaft preferably
secured rigidly at the respective extremities thereof to the end plates a². Howevei,
this shaft, may be supported in suitable bearings and permitted a freedom of
rotary motion. 6, are wheels provided, respectively, with laterally projecting
hubs c., are ratchet-wheels having V-shaped teeth c³, Figs. 1, 2 and 3, and.
attached to or formed integral with the hubs c. ', Figs. 1 and 2, are spring-
actuated pawls attached respectively to the wheels c, and provided with V-shaped
extremities, adapted to engage in the V-shaped teeth e, of the ratchet-wheels c*.
These pawls c, and ratchet-wheels e, serve to transmit motion from one of the
series of wheels c, to the other wheels of the series and the V-shaped extremities c",
of the respective pawls e, permit the successive wheels c, of the series to continue
to revolve after the preceding wheels of the series have been brought to rest by
friction and until the former are arrested by the sliding-contact of the ends of the
respective pawls between two of the ratchet-teeth. Moreover, the spring actuated
pawls e, cause each of the wheels c, to turn either in one direction or the other
before coming to rest, so that the numbers or characters upon the periphery of each
of the wheels may come opposite or nearly so, to the opening a³. It being under-
stood that there are as many teeth upon each ratchet-wheel c² as there are numbers
or characters disposed around the periphery of each of the wheels c.
, is a sleeve loosely mounted upon the shaft, and provided with a pinion d',
and with a ratchet-wheel d², having saw-teeth d³. d, is a spring-actuated pawl
attached to the first wheel of the series of wheels c, and adapted to mesh with the
saw-toothed ratchet-wheel d², so that when the sleeve d, is rotated toward the right
in Fig. 2, the ratchet-wheel d², engages the pawl, and rotates the first wheel of
the series with a positive motion, and the rotary motion of this wheel is transmitted
to the other wheels of the series by means of the ratchet-wheels c* and pawls c.
When the sleeve d, is rotated in the other direction, that is, towards the left, in
Fig. 2, the pawl d', slides over the saw-teeth d³, of the ratchet wheel d, without
imparting motion to any of the wheels c.
e,
is a rack-guide attached to one of the sides a², of the case a, and provided with
ways e and with a projection e².
is a rack adapted to mesh with the pinion d', and provided at the rear thereof
with a longitudinal recess f". This rack f, is adapted to be shifted in the ways e',
and is prevented from moving in a vertical direction by the projection e², working
in the recess, in Fig. 1. are longitudinal ways formed in the face of the
rack, Fig. 4.
, is a sliding-plate supported in the ways e, and provided with a feather ',
working in the ways f, of the rack.
, is a hand-knob attached to the sliding-plate y, and protruding through a
slot a³, formed in the side a², of the case a, so that the plate y, may be shifted in
either direction by the simple operation of shifting the hand-knob h, in the slot a",
as shown in Figs. 1 and 3.
8,
is a spiral or other preferred forin of spring attached at one extremity thereof
to the sliding-bar g, and at the other extremity thereof to the casing a.
This

page_text: spring, serves to retain the sliding bar g, in its normal position as shown in Fig. 2
and to return the same to such position. a8, is an aperture formed in the casing a,
and adapted for the reception of coins.
i, is a chute for conducting the coins from the aperture a, to a pocket, Figs. +
and 5. This pocket i, is located between the rack f, and sliding-plate g, and is
formed by the edges 12, of the feather g', and the edges, of the ways of the
rack, is a slot located beneath the extremity of the chute i, and adapted to
permit of the passage of coins of less than a predetermined diameter past the
sides or edges and ³, and through the pocket i¹. It will be understood that coins
of larger than a predetermined diameter cannot be inserted into the aperture a².
When a coin of a predetermined diameter is inserted in the aperture a, it
descends through the chute i, and comes to rest in the pocket, with its periphery
in engagement with the edges 2 and 3, as shown in Fig. 4, thus forming a connec-
tion between the sliding-bar 7 and rack f, so that when the former is shifted by
means of the knob h, towards the right in Fig. 2, the coin 7, causes the rack to
travel with it toward the right in Fig. 2. The knob h, is released as soon as the
sliding bar I: and rack, have been shifted into their extreme right-hand positions,
whereupon the edges 2 and 3, are separated slightly and the coin, being thus
released drops through a slot i, in the rack-guide e, past a partition", Fig. 1,
into the bottom of the case a, so that the sliding-plate g, is released from the rack
and is returned automatically by the spring s, to its normal position. As soon as
the rack is released from the sliding-plate y, by the escape of the coin 7, the
springs, which is attached to the rack, and to the rack-guide e, causes the rack
to be shifted toward the left into its normal position, thus imparting motion to the
sleeve d, and series of wheels c, as has been above explained. In practice the
coins, may be removed from the bottom of the case a, by means of a door or in
any other preferred manner.
The above described machine may be used as a incans for furnishing amusement
by depositing a coin of the proper diameter, in the slot a", then shifting the hand-
knob and rack f, toward the right in Fig. 2, and releasing the hand-knob, whereupon
the coin, falls to the bottom of the case a, and thus permits the springs', to cause
the rack to rotate the wheels c, and finally guessing the designs, numbers or
characters which will be visible through the opening a, after the wheels e, have
come to rest.
The construction and mode of operation of the modified form of wheels
illustrated in Figs. 6 and 7, are as above described with reference to Figs. 1, 2, 3, 4
and 5, with the following exceptions, that the ratchet wheels e, are provided with
saw-teeth c³, disposed upon one of their respective faces and the pawls c, are
struck up from the hubs of the wheels c, and are provided with extremities adapted
to engage with the saw-teeth e, when the ratchet-wheels are rotated in one
direction and to slide or travel freely over the same, when the ratchet-wheels are
rotated in the other direction.
In the drawings, with special reference now to Fig. 8, a, is a case or housing of
any preferred shape and construction comprising a base a', ends a² and curved side
and top plates a³. a', is an opening protected by a glass cover formed in the top a³,
of the case a, for a purpose to be hereinafter fully described.
, is a fixed shaft rigidly supported in lugs ', attached to the ends a², of the
case a. 12, are arms keyed or otherwise secured to the shaft b, and provided with
spring-actuated pawls c.
c. are wheels having numbers, designs or characters disposed on their peripheries,
and the said wheels are mounted on the fixed shaft, so as to freely rotate
thereon.
c, are milled peripheral edges formed upon the wheels c, for a purpose to be
hereinafter fully described.
, are ratchet-wheels attached to or formed integral with the character-wheels c.
These ratchet-wheels c², of course, are free to rotate on the fixed shaft b, and
engage with the spring pawls c'. The teeth e, of the ratchet-wheels c³, and the

page_text: extremities c³, of the pawls c', preferably have V-shaped edges, so that when the
wheels c, are being rotated the pawis c', slide freely over the teeth of the ratchet-
wheels c, and when the wheels c, are about to be brought to rest by friction,
the V-shaped extremities c, of the pawls c', are forced between two of the ratchet-
teeth and cause the wheels c, to be turned either in one direction or the other and
brought to rest with the numbers or characters opposite the opening a', or nearly
SO. It being of course understood that there are as many teeth upon each ratchet-
wheel, as there are numbers or characters on the peripheries of each of the
wheels c.
k, is a rotatable shaft supported in bearings k', attached to the ends of the case a,
or supported in any other preferred manner.
2, is an arm keyed or otherwise attached to the shaft k, and provided with a
spring detent d, for a purpose to be hereinafter fully described.
k, are spring-fingers keyed or otherwise attached to the rotatable shaft k, and
adapted to contact, respectively, with the milled peripheral edges e, of the wheels c,
when the shaft k, is rotated, and in order to impart rotary motion to the wheels c.
Excellent results have been attained in practice by making the working extremities
of the fingers k*, of rubber or analogous material and hence preference is given to
the employment of such type of spring-fingers.
d2, is a ratchet-wheel formed integral with the pinion d', and mounted loosely
on the shaft, so that the pinion d', and ratchet-wheel d, are connected together
and may be revolved freely on said shaft. The ratchet-wheel d², is provided with
saw-teeth adapted to slide freely past the detent d, when the pinion d', is rotated
toward the right, in Fig. 9, and to engage the detent d', and rotate the shaft k,
when the pinion d', is rotated toward the left in Fig. 9.
e, is a rack-guide attached at the respective extremities thereof to the sides of the
case and provided with ways e¹.
, is a rack working in the ways el, and adapted to nesh with the pinion d', so'
as to rotate the latter, when the rack f, is shifted.
9,
is a sliding-bar provided with a hand-knob h, and supporting-guide g*; and
adapted to overlap the rack f.
is a slot formed in the sliding-bar g, and located in the portion thereof which
overlaps the extremity of the rack f.
, is a slot formed in the rack f, and located beneath the slot ³, but out of line
therewith so as to lock a coin 1, of a predetermined diameter in said slots 16 and i
in order to connect the rack and sliding-bar g, together.
a, is a coin slot or receptacle formed in the casing a and adapted for the reception
of coins of a predetermined diameter.
i, is a chute communicating with the slot a, and adapted to conduct the coins
to and discharge them into the slot ³, in the sliding-bar y. It may be remarked
that if the coins are of less than a predetermined diameter they will pass through
the slots and, and through an opening, cut in the rack-guide e, and there-
fore will not serve to connect the sliding-bar y and rack together, so that the
former may be shifted without affecting the operation of the machine; but if the
coin is of a predetermined diameter it will be locked in the slots and, and will
serve to connect the rack f, and sliding-bar y, together, so that when the sliding-
bar g, is drawn or pulled by means of the hand-knob h, or in any other convenient
manner, toward the left in Fig. 9, the rack f, is also shifted in the same direction.
This motion of the rack, causes the pinion d, to be rotated toward the right in
Fig. 9, so that the detent d', slides over the teeth of the ratchet-wheel d, without
imparting motion to the shaft k.
and having the
formed in the
This spring,
outward; that
2, is a spring attached at one extremity thereof to the casing a,
other extremity thereof fitted into and passed through a recess
sliding-bar g, so as to contact with the end of the rack, Fig. 9.
is of course compressed by the operation of pulling the hand-knob
is, toward the left, in Fig. 9. When the knob h, is released after having been
pulled to its extreme position, the spring s² serves first, to shift the sliding-bar g,

page_text: slightly toward the right, whereupon the slots and, are brought into line with
each other, thus unlocking the coin and permitting it to fall through a slot 10,
formed in the rack-guide e, into the bottom of the housing a; and second, to shift
the sliding-bar g, and rack, toward the right in Fig. 9. This movement of the
rack, toward the right causes the pinion to be rotated toward the left. During
this rotation of the pinion d', the detent engages one of the teeth of the ratchet-
wheel, so that the detem d, is rotated with a positive motion. The rotation
of the shaft k, causes the spring-fingers, to contact with the milled edge c, of
the peripheries of the wheels c, and to rotate the latter in the direction indicated
by the arrow in Fig. 9. The wheels c, will continue to rotate until their motion
is retarded by the friction of the pawls c', sliding over the teeth of the ratchet-
wheels c, and as the wheels c, gradually come to rest the pawls c, are forced
between the ratchet-teeth e, and cause the respective wheels c, to be turned
either in one direction or the other, so that they finally come to rest with the
numbers or characters opposite or nearly so, to the opening a, as has been above
explained.
In use the coin of a predetermined diameter is deposited in the slot a³, and is
conducted through the chute i, whereupon it becomes locked in the slots 2 and 2*,
and serves to connect the rack and sliding-bar g. The participants in the amuse-
ment may then guess the characters, designs or numbers that will be visible through
the opening at, after the wheels c, have been rotated and have come again to a
position of rest in the manner hereinabove explained.
It may be remarked that coins may be removed from the casing a, by means of
a door or in any other preferred manner.
