4 Claims.
This invention relates to a type of stereopticon slides on which transparent circular disks, carrying radially disposed markings or data, are adapted to receive a temporary whirling motion, which, with the ending of such rotation, will indicate the winning combination of the markings which are found in aligned relation of a particular marking of each disk, with the single marking on the border of a circular light opening the front wall of the stereopticon slide. The device being more especially intended for use in motion picture exhibition during intervals in such exhibitions in which the withdrawal of a picture film from the projection machine used and the introduction therein of a succeeding picture film, during which intervals a display is given on the picture screen of the markings of the disks and the final result or combination'found in register on the stopping of the whirling of the said disks. And this improvement has for its object:
To provide a structural formation and combination of parts and features in a stereopticon slide of the type above referred to, comprising a pair of transparent disks capable of receiving independent whirling impulses from the operator in charge, said disks being arranged in operative relation to the usual transparent circular light passage in the front wall of a stereopticon slide of the present type. The disks and the border of said light opening carrying related data or markings, which, after the whirling or rotation of the disks comes to a stop, a related marking on one disk with a related marking on the other disk found in aligned relation with the single marking at the border of the aforesaid light opening in the front wall of the slide will indicate the wimiing combination or result at the end of the display, and thereby afford an interesting exhibition of the chance operation of the device, all as will hereinafter more fully appear.
In the accompanying drawing:
Fig. 1 is a front elevation of a stereopticon slide embodying the preferred form. of this invention, portions of the device are broken away to disclose portions of the rearwardly arranged members of the device.
Fig. 2 is a horizontal section on line 2-2, Fig. 1. Fig. 3 is a fragmentary section on line 3-3, Fig. 1.
Like reference numerals indicate like parts in the different views.
In the preferred form of this invention, as shown in the drawing, the marginal frame I of the stereopticon slide is of the ordinary rectangular shape, and of a like shape in cross section of its component rails, with said rails formed mid-' way of their widths with inner tongues 2, the dual function of which is to maintain the forward and rearward transparent plates 3 and 4 in proper spaced relation and provide a central chamber in the slide for the reception of the pair of whirling chance disks now to be described.
In coacting relation to the above described markings of the disks 5 and 6, the forward transparent plate 3 of the slide is provided with a stationary marking or line 1, adapted to register with and indicate the winning combination of the symbols and markings of the whirling disks 5 and 6 which may chance to come into register with said marking I as said disks come to rest at the ending of their whirling movements, with a resulting very clear display on the picture screen of the winning combination.
With a view to greater clearness in said display, the transparent forward plate or panel 3 of the slide will be provided with a layer or covering 8 of light intercepting material except as to a central and circular portion of the front plate or panel 3 left transparent and in alignment with the disks 5 and 6 aforesaid.
Any usual means capable of imparting a rapid whirling impulse to the transparent disks 5, 6, may be employed without departing from the scope of this part of this improvement. In the preferred construction shown in the drawing, a blast of air is employed as the impelling means with a structural arrangement of parts as follows:
Each disk 5, 6, is provided with a marginal metal enclosure 9, which in turn is provided with a plurality of radiallydisposed blades l adapted to receive the impact of a moving body of air, which moving body or blast of air is conducted by bifurcated passages H in the frame which have tangential relation to the periphery of the disks and 6 and the radial blades Ill arranged thereon.
The supply or blast of air for the above stated use is under the control of the operator and can be readily provided by a compressible bulb of rubber or the like, the outlet of which has communication with a main passage l3 in the frame I, with said main passage having communication in turn with the bifurcated passages H, H aforesaid.
Having thus fully described my invention, what I claim as new, is:-
1. A stereopticon slide of the type herein described, comprising a marginal frame formed with a central chamber, means for supporting a journal shaft or spindle centrally in said chamber, a pair of transparent disks mounted on said journal shaft for independent whirling movements, with one of said disks carrying radially arranged symbols or marking adapted for chance registry with one or another of circular plurality of numerals carried on the companion transparent disk on the stoppage of the whirling movements of said disk, a stationary index or pointer carried on the frame or slide for registry with the winning symbol and numeral of the disks, and means for imparting whirling impulses to said disks.
2. A stereopticon slide as specified in claim 1, wherein the means for effecting whirling movements of the pair of transparent disks comprises a main air supply passage in the frame of the slide ending in bifurcated discharge passages in tangential relation to the peripheries of said disks, with said main passage being adapted for connection with a source of air pressure.
3. A stereoptlcon slide of the type herein described, comprising a marginal frame, forward and rearward transparent plates secured within said frame in spaced relation to provide a central chamber, a journal shaft or spindle mounted centrally in said plates,-a pair of transparent disks mounted in said journal shaft for independent whirling movements, with one of said disks carrying a plurality of radially arranged symbols or marking adapted for chance registry with one or the other of a plurality of circularly arranged numerals carried by the companion transparent disk on a stoppage of the whirling movements of the disks, a stationary index or pointer mauled by the forward transparent plate of the slide for registry with and indicative of the winning combination symbols and markings of said disks, and means for imparting whirling impulses to said disks.
4. A stereopticon slide as specified in claim 3, wherein the means for effecting whirling movements of the pair of transparent disks comprises a main air supply passage in the frame of the slide ending in bifurcated discharge passages in tangential relation to the peripheries of said disks, said main passage being adapted to have connection with a source of air pressure.
