VIEW MECHANISM FOR'SLOT-MACHINES.

SPECIFICATION formng part of Letters Patent NO. 678,936, dated July 23, 1901.

Application filed November 1,1900. Serial No. 35,152. (No model.)

To all whom, it may concern:

Be it known that I, FRANK BRONORI, a citizen of the United States, residing at Bennington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in View Mechanisms for Slot-Machines; 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.

It is desirable in the Construction of mechanism of the type for displaying pictures to provide for the interchange and the substitution of the picture-hearing plates,` so that the same carrier may be used with a great variety of pictures. It is essential that the picture-plates be prevented from casual 'displacement and from occupying a difierent relation with reference to the stereoscope. Hence means are provided and combined with the picture carrier to positively hold the plates in position and admit of their removal and replacement as desired.

The invention consists, essentially, of the novel features, details of construction, and combinations of the parts which hereinafter will be more particularly set forth, illustrated, and finally outlined in the subjoined claims.

In the drawings, Figure 1 is a front view of the picture mechanism, showing it in operative relation. Fig. 2 is a transverse section showing illuminator, the eleetrie cireuit therefor, and the means for closing said circuit from the stereoscope. Fig. 3 is a detail view in elevation of a portion of the picturecarrier with some of the plates in position. Fig. 4 is a detail section about on the line X X of Fig. 3. Fig. 5 is a perspective View of coperating bars between which a picture is held. Fig. 6 is a detail View in perspective of a drum for supporting the carrier.

Similar parts are indicated by corresponding numerals in all the views of the drawings.

The picture-carrier is of the endless type and comprises two belts 1, disposed in parallel relation and composed of leather, textile, or any fiexible material. These belts are connected by a series of transverse bars 2 and 3, grooved in their opposing sides to receive the plates 4, hearing the pictures to be exhibited.

These bars 2 and 3 are provided in pairs and are Secured to the endless belts 1 in any substautial and convenient manner, and, as shown, their terminal portions are fiattened and pierced to receive rivets or analogous fastenings by means of which the attachment is effected. The flattened terminals of the bars 2 and 3 are in line with one side of said bars, thereby throwing the grooved portion clear of the belts 1, so as to admit of the plates 4 being readily placed in position or removed, as desired. The bars 2 are formed at one end with hooked extensions 5, oonstituting fixed steps to limit the movement of the plates 4 when placed in position, and springstops 6 are formed at the opposite end of the bars 2 to prevent outward displacement of the plates 4 when positioned, said plates being confined between the steps 6 and 5. By having the steps 6 constructed so as to spring they can be moved aside when it is required to place the plates 4 in position or to admit of their removal, as may be required. These bars 2 and 3 may be cast or struck up from sheet metal and may be of any weight in order to insure stability of structure.

The picture-carrier is supported upon upper and lower drums 7 of like formation. The drums 7 are of skeleton Construction for the sake of lightness and also to admit of the unobstructed passage of light-rays from the illuminator through the upper drum, so as to display the pictures to the best possible advantage. In cross-section the drums are of triangular shape and are composed of end pieces 8 and cross-bars 9, journals 10 projeeting outward from the center of the ends 8. The sides of the drums are of like dimensiens and correspond approximatelyto thesize ofthe pictures. The picture-carrier may be operated in any desired way, and, as shown, a power-driven shaft ment 12 of which is provided with an offstanding pin 13 to coperate with a spur-wheel 14, attached to a journal 10 of the uppermost drum 7, and as the gear-wheel 12 makes a complete revolution the pin 13 will engage witha spur of the wheel 14 and move it a distance to bring the next picture of the series into position for observation. Within the purview of the invention mechanism of any form may be devised for imparting movement to the picture 11 is included in a train of gearing, a gear ele- IOO mechanism. The train of gearing is released by means of a coin directed by the chute 15 onto a pan 16,`attached to a rod 17, which normally extends in the path of a stop 18, attached to a gear element 19 of the train of gearing and shown as mounted upon the power-actuated shaft 11. When the coin of given value is dropped into the machine, the motive power is released and the picture mechanism set into operation, the views being successively brought into position opposite the stereoscope 20.

The illuminator 21 consists of an incandescent electric lamp included in an electric circuit comprising the terminals 22 and 23, which normally stand apart and which are adapted to be brought into contact by means of a push-bar24, arranged so as to be pressed upon the forehead of the person looking into the stereoscope. This push-bar 24 s springactuated and is provided at its outer end with a button or pad 25, located at the upper side of the stereoscope, in position to be engaged by the forehead of the person when looking into the machine. The spring 26, by

means of which the push-bar 24 is held projected at its outer end, is exceedingly light,

being of sufficient strength only to move the bar 24, so as to project the button or pad 25 and admit of the electric Contacts 22 and 23 being normally separated. The illuminator 21 is Conveniently located so as to light up the pictures and ad mit of their exhibition to the best possible advantage.

Having thus described the invention, What is claimed as new is l. In combination, corresponding endless belts, pairs of bars having their terminal portions flattened and oifset and attached to the said endless belts, and having their opposing sides groeved to receive picture hearing plates, and integral steps at the extremities of a bar of each pair of bars, one of the stops being yieldable to be sprung aside, substantially as and for the purpose specified.

2. In picture mechanism, of the type substantially as set forth, comprising a carrier hearing pictures, an illuminator to light up the pictures and included in an electric circuit, a stereoscope, and a circuit-closing de- -vice coperating with and in close proximity to the stereoscope to be engaged and operated by the head of the person when pressing close to the stereoscope, substantially as described.

3. In picture mechanism, of the type substantially as set forth, comprising a carrier hearing pictures,- au illuminator to light up the pictures and included in an electric circuit, a stereoscope, and a circuit-closing device comprising a movable part within the limits of the eyepiece of the stereoscope so as to be engaged and pressed upon by the head of the person Viewing the picture through the stereoscope, substantially as and for the purpose specified.

In testimony whereof I aflx my signature in presence of two witnesses.
