COIN-CONTROLLED SURFACE EXHIBITQR.

SPECIFICATION forming part of Letters Patent No. 523,569, dated July 24, 1894. Application filed April 30, 1894. Serial Ne. 509,506 (No model.)

To wlZ whom it may cancer-n,.-

Be it known that I, Vcroa P. DE KNIGHT, acitizenof the United States,residingatWashington, in the District of Columbia, have invented certain new and useful Improvenents in Coin-Controlled surface Exhibitors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Ths nvention relates to coin controlled surface exhbtors; and it consistsin the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings: Figure l is a 'front view of the Operating mechanism secured inside the case. Fig. 2 is a vertical section taken On the line a: ao in Fig. 1. Fig. 3 is a plan View of the coin-operated bell-crank lever; and Fig. 4: is a side view of the same and the coin guide plates.

A is an inclosing case of any convenient form or desgn, and a is a plate to which the working mechanism of the device is secu-red.

B is a bracket secured to the plate a, and b is a pin secured to the said bracket and projecting through a hole in the plate a;

O is a sleeve journaled on the pin b and arranged to turn thereon with as little friction as possible; and c is an exhibiting disk secured to the said sleeve O; v

D is a stationary disk secured on the end of the pin b. D' is a glass window arranged in front of the disksD and c, but this window may be dispensed with if desired. The front window D'.

of the disk c is the surface upon which the pictures or other subject matter to be exhibited are placed.

The pictures are exhibited by the 'disk c when revolved, and may be seen through the A pointer d or a mark on the disk D is used to call attention to whichever picture or subject that maybe behind it when the disk c stops after having been revolved or'spun, or, if desired, the window D' may be partially opaque and have only a small sight hole through which 'a single picture or sub-` ;ect may be displayed in the manner commonly used in picture exhibitors of this class. -The pictures may be men, horses or other E to run loose on the sleeve C '0, and e is a spring-actuated pawl pivoted to the wheel E and engaging with the ratchet wheel.

in one direction. i i

F is a toothed segment journaled on the pinfprojecting from the plateagand f' is a spring normally holding the toothed segment out of gear with the toothed wheel E.

G is a plate Secured to the front of the-plate a and provided with a slot g of a size suitable to permit a small coin, such as a cent, to be inserted through it, and 'to pass through a hole in the plate a.

H are guide plates adjacent to the slot g. These guide plates are of any convenient size and shape which will prevent the coin from dropping prematurely when thrust into the slot.

I is a bell-crank lever pivoted on the pini behind'the slot g. One arm h of this bellcrank lever is arranged in the path of the coin and is preferably curved and provided i with a rounded edge so that the/coin may slip off it suddenly.

J is the chute the coin slides down after passing through the slot g.

w The other arm of the bell-crank lever I is pivotally connected to the toothed segment F i by the rod t".

When a coin is thrust through the slot g it pushes back the arm h, as shown in Fig. 3, and moves the toothed segment F into gear with the wheel E. When the ratchet mech- This ratchet wheel permits the wheel anism is not used the toothed segment re- I volves the disk c for a part of a revolution, and the use of the said ratchet mechanism is to permit the toothed segment to revolve the wheel E for a part of a revolution in one di rection without turning the disk c. When the coin slips off the arm h and falls' down the coin chute, the spring f' pulls back the toothed segment suddenly. 'This gives the IOO toothed wheel E and the disk c a sharp spin, and they continue to revolve for some time after the toothed segment has passed out of gear with the wheel E. The impulse given to the disk c is a mere matter of chance depending upon the slipping of the coin off the arm h and the accidental suddenness with which the springf' is permitted to act. The positon of any particular picture or motto on the dsk c with regard to the pointer or sight hole when the disk stops, is therefore a matter of great uncertainty and this constitutes the attracton or pleasure to be derive'd by using the devce. The toothed segment is prefer-` ably provided with stops h' to limit its movements.

In order to prevent the device from being use d otherwise than by inserting a coin in a legtmate nanner, a toothed bar K is pivoted on the pin Ic projecting from the plate a.

M is a spring which normally supports the bar K and holds it in contact with the under side of a pin m which projects from the toothed segment F. The bar K is provided with a plate 76' at its end, and this pl'ate is arranged under the coin chute. It' a knit'e blade is inserted through the coin slot, the

' l arm his pushed back and the toothed segment is turned to the left, but the spring f' falls to spin. the disk c because the teeth of the bar K engage with the pin m and prevent the toothed segment from moving to the right.

When the device is operated by a coin inserted in a legitimate manner, the toothed segment is first turned to the left and the pin m caused to engage with one or another of the teeth of the bar K according to the accidental slipping of the coin off thearm h, and the toothed segment is then released suddenly by the weight of the coin which falls onto the plate k' and depresses the toothed bar K. The coin then slides off the plate k' and falls to the bottom of the case A.

What I claim is 1. The combination, with a revoluble exhibiting disk, and a toothed wheel operatively connected therewith; of a pivoted toothed segment adapted to gear into the toothed wheel, a plate provided with a coin slot, an arm pivoted behind the slot in the path of the coin, and operated thereby when pushed forcibly through the slot a rod pivotally connecting the said arm and segment,'and a spring normally holding the said segment out of gear with the said wheel Operating to retract the segment and spin the exhibiting disk upon the passage of a coin past the said arm, substantially as set forth.

2. The combination, with a re voluble exhibiting disk, a toothed wheel journaled concentric therewith, and ratchet mechanism connecting the said disk and wheel and permitting the wheel to run loose in one direction; of a pivoted toothed segment, a spring normally holding the said segment out of gear with the said wheel, a pivoted arm adapted to be forcibly pushed back by a coin, and a rod pivotally connecting the said arm and segment, whereby the disk is spun upon the passage of a coin past the said arm, substantially as set forth.

3. The combination, with a revolubleexhibiting disk, and a toothed wheel arranged concentric with the disk and operatively connected with it of a pivoted toothed segment,a spring normally holding the said segment out ot' gear with the said wheel, and a pivoted arm connected with the said segment, and adapted to be forcibly pushed back by acoin thereby moving the segment into gear with the wheel and permitting the said spring to retract the said segment and spin the said disk when the coin slips past the said arm, substantially as set forth.

4. The combination, with a revoluble exhibiting disk, and a toothed wheel operatively connected therewith; of a pivoted toothed segment-provided With a projecting pin, a spring-supported toothed bar engaging with the said pin, Coin-controlled Operating devices for moving the toothed disk into gear with the said toothed wheel, and a spring for retractin g the said toothed segment suddenly and causing the said disk tospin freely upon the insertion and descent of a coin, substantially as set forth.

5. The combination, with a revolu ble exhibiting disk, and a toothed wheel operatively connected therewith of a pivoted toothed segment, a plate provided with a coin slot and coin guide plates, abell-crank lever pivoted behind the slot and having one arm arranged between the guide plates in the path of the coin, a rod pivotally connecting the other arm of the bell-crank lever with the toothed segment, and a spring normally holding the toothed segment out of gear with the said wheel and Operating to spin the said disk upon the insertion of a coin, substantially as set forth.

In testimonywhereof I afiix my signature in presence of two witnesses.
