COIN-OPERATED STEREOSCOPE.

SPECIFICATION forming part of Letters Patent No. 405,321, dated J une 18, 1889.

Application led February 10, 1888. Serial No.. 263,607. (No model.)

To all whom t may concern.'

Be it known that I, CLARA E. PATTERSON, of the city, county, and State of New York, have invented an Improvement in Coin- Operated Locking Devices for Stereoscopes an d Similar Apparatus, of which the following is a specification.

My invention has reference to coin-operated devices for stereoscopes and similar apparatus; and it consists of certain improvements which are fully set forth in the following specication and shown in the accompanying drawings, which form part thereof.

While my invention has particular bearing upon stereoscopes as knownin the market, it is understood that it is adapted to any and all devices in which a handle 'is to be rotated by the person who is to receive an equivalent for the money deposited. The essential features, broadly considered, may be enumerated as a handle to operate something, which in a stereoscope is a chain of pictures, a locking device, substantially such as hereinafter set out, to prevent the rotation of the mechanismoperated by the handle except when a coin is deposited, and devices Clescribed later on to automatically relock the mechanism after it has been given a predetermined number of movements by the handle.

To prevent the cheating of the machine by the deposit of buttons and other articles not legal tender, I employ a push-pin which forcibly pushes the coin between sliding bolts, whereby the power of the hand can put the lock out of action, and the size and strength of the coin, rather than its weight, are employed to insure the unlocking of the devices for operation.

In the drawings, Figure l is a front elevation of a stereoscope and locking device embodying the principles of my invention, having a portion of its outer casing or box removed. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of the coin-operated mechanism. Fig. 4 is a sectional viewof the coin-guide and push-pin to one side of the line of Fig. 5, which is a Vcross-sectional view through the line y f l/ of Fig. 4. Fig. 6 is a perspective view of the mechanism operated by thc coin detached from the case, and

less chain or band guided upon a drum D.

The drum D is preferably square, and is rofated by a shaft d, to which it is attached, and which terminates in a handle E on the outside of the box. Each of the picture-holders C (of which there may be any number desired) is provided with a picture c, which are successively presented before the sight-aper ture B upon rotating the drum D by means of the handle E. Normally, however, the drum D and endless chain cannot be rotated by the handle E because of the locking devices, hereinafter described, and it is not until a coin has been deposited in the box that the mechanism can be unlocked and the drum and endless chain rotated by the handle E.

F is aratchet-wheel secured to the drum D and upon its shaft d, and f is a locking-pawl therefor to prevent backward movement.

G are spur-gearing meshing together, one of which is mounted on the drum-shaftd and the other upon the shaft H. This shaft I- I is located wit-hin the frame of the box, j ournaled in a support or framework Within it, and is provided with a pin or projection h, which is adapted to be engaged by a locking-bolt.

K is the locking-bolt, supported in any suitable manner within the box4 and having a beveled or tapering end la. This locking-boltK has an angular end K', which is normally adapted to rest. against the projection h on the shaft H. K2 is a rod or bolt similarly provided with a tapering end 7c. These two bolts K and K2 are loosely supported in their frames, so asv to admit of lateral reciprocation.

L L are springs to normally keep the bolts in place with their beveled ends k k at a given distance from each other.

M is a latch-hook pivoted by a pin to the box A or otherwise, as desired, and is adapted to catch the end K when it is forced beneath it. This latclbhook M is provided withan IOO arm m, extending from its side and adapted to be struck and lifted by a pin N upon the shaft H.

J is a push-pin having a spring j and located in the box A in front of the bolts K and K2 and between their beveled ends L k.

I is the coin-guide tube, having a slot or coin-aperture 'z'. to receive the coin of the exact size. This tube I extends downward through the box A, and is provided with openings through which the tapered ends 7c k of the bolts K and K2 and the end of the push-pin J may enter. At this point it preferably has a slight bend or elbow.

In operation the coin is dropped through the aperture fz, and, falling through the tube I, is caughtbetween theends 7i'. 71; of the bolts K and IYQ upon the elbow or bend in the tube. If the pin J is now pushed in, the coin will be forced between these ends 7.: k', which will thus be forced apart. rlhis will push the end K away from the projection h. The latchliool( M now catches the end K and'holds the bolt K back. The handle E may then be rotated, and the pictures will be presented. in succession to the eye; but when the shaft ll has made one complete revolution the latchpin N strikes the arm m, lifting the latch-hook M and freeing the bolt K, which, by virtue of the spring L, 'will be drawn back, and the end K will engage again with the projection 71 and the apparatus will be relocked.

O is a drawer to receive the coins.

It is evident in this construction that the springs L might be replaced by a weighted lever, as shown in dotted lines in Fig. (i.

The number of pictures presented to the eye upon each revolution of the shaft Il may of course be varied by changing the relative sizes of the spur-gears G, as illustrated in Figs. 2 and 7.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A rotating shaft having a projection, a tube or coin-passage, a bolt to normally hold said projection and shaft from rotating, said bolt extending or projecting into the tube in the path of the coin, whereby the coin in pass ing `through the tube moves said bolt and releases the shaft, allowing it to be rotated, a latch to hold said bolt away from the shaft projection, and a second projection carried by the shaft to trip the latch and release the bolt.

2. In a stereoscope, the combination of a picture-holder provided with a series of pictures, a rotating shaft to move the pictureholder, a handle to rotate said shaft and picture-holder to move the pictures successively before the sight-aperture, a projection upon said shaft, a coin-receiver provided with an aperture an'd terminating in a support, a pushpin to push the coin from one position without turning it over, and a bolt to prevent the rotation of the shaft and picture-holder proj ecting in the path of the coin and operated by it, when pushed, to release the projection on the shaft and allow the picture-holder to be rotated by the handle to cause the pictures to be moved successively before the sight-apertures.
