Specification of Letters Patent.

Patented Sept. 3, 191?.

1 Ap lication filed May 20, 1911. Serial No. 628,359.

Be it known that I, ALFRED M. citizen of the United States, residing at Franklin, in the, county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Stereopticons,'- of which the following is a specification.

' The .ob'ect, construction, and operation of my improved stereopticon are herein set forth with sufiicient clearness-to enable those skilledin theart to which it appertains to make and use the'saine, reference being had to the accompanying drawings which form a part of this application, the several views whereof are as follows:

Figure 1 is a' front elevation of ofmy stereopticon showing the same inclosed for out-door use. 'Figs. 3, a, 5,6 and 7 are details.

The same reference numerals are applied to identical parts in all the views. 7

The object of my invention is, to providea stereopticon for the particular purpose of displaying advertising matter, though other information or illustrative matter may be displayed thereby as desired. I

The construction of my improved stereopticon is as follows: I construct a wheel composedof a hub 1, having a number of'radial arms 2, each-of which is provided upon its outer end with a plate or transparencyholder 3. Said wheel is mounted between brackets 4 and 5 so as to revolve vertically. Mounted-upon one side of said wheel and adjustably positioned with reference t ereto, is a condenser 6, and positioned in proximity to said condenser is a suitable'light 7.

Upon the opposite side of the wheel, and in correct register oralinement with the plate V number of pins 9-which project outwardly from said hub in a line parallel with the axis of said wheel. Below the center of said wheel is revolublv mounted a shaft 10, suit-'.

SMILEY,-

my im proved stereopticon, Fig. is'a side elevation able bearings for which are provided in brackets 5 and 11. The end of shaft- 10 approximate to the wheel projects through its bearing and has an arm '12 rigidly affixed thereto which, as the. shaft 10 revolves, is

adapted to engage a pin 9 and revolve wheel 1 sufliciently to bring a succceding approximate. frame 3 into'its proper position of registry with the lens and light, sothat its subject will be thereby projected upon the screen. I arrange to .revolve shaft 10 con.- tinuously, and the mechanism provided for this purpose is-as follows: T 0 said shaft-10 is secured a worm-wheel 13- which meshes ith d i d i en vbyzaworni 14 which is suitably mounted in bearings carried by the bracket 11. Upon the worm-shaft is aflixed a pulley 15 which. receives power flUIH-HII electric motor 16. this arrangement, it-

'will beradily understood that while'shaft '10 revolves constantly, wheel 1 is moved intermittently, each movement being an amount siifiicient to bring'one of the various .holders into register with the projecting medium where the sameyis caused to rest for a certain interval 'of'time, said interval being during one revolution of shaft 10.

In order to insure a positive stopping'of' the wheel in the desired position, 'and its retention there during the allotted interval, I provide'a resilient detcnt, which is shown in section in F ig. 4, the construction of which is as-follows: In the face of the wheeLhub are formed a number of depressions 18. In the-bracket 5 is inserted a tubular post '17, which is arranged-withits outer open end in close proximity to the face of the wheel-hub. -Within the bore of said post is placed a ball 18, arranged to occupy a depression 18, when said depres sion passes or is positioned in front of post 17. Ball 18 is pressed outwardly by means of a spiral spring 19, the pressure of which.

the following construction: The bracket 21- which carries the lens is mounted upon two rods 22, 22, (Fig. 7,) so that it may slide longitudinally thereon,a' screw-threaded rod 23 passes through the bracket 21, and the slceve24: is formed into a nut to engage said 5 rod 23, and by turning said rod by means of the wheel'25, the desired adjustment may be obtained. I also provide for adjusting the condenser 6 with reference to the light 7,

. Which'is accomplished in the followinginan' l0 ner: The -bracket -26, that-carries the said condenser,'is mounted to slide upon the Ways 27 (Fi-g. 6) and by turning the screw28, WhlCl'L passes through the screw-threaded yoke 29, I said bracket and-'thethereto at-- -tached condenser may be adjusted as desired; A thunih vvheel 80 is attached to screw 29 for the purpose of revolving said screw. v

In Fig. 2 I have shown my improved 20 stere'opti'con inclosed in a box or cas'e,-as it is constructed for outdoor service-for advertising purposes, and this View shows an electric switch 31, wit lrconductors 32, passi ing to the light and other conductors 33 passing to. the motor; 16.

mission between the motor and pulley '15 may be substituted for a belt, as for instance a chain or gears. j I am. aware of the construction shown in certain Letters Patent of the United States issued to William G. Spiegel 'on the 12th day of April, 1892 for magic lantern advertising apparatus, but I hereby expressly forth.

Any suit-able light may be used, also any suitable trans-i What. I claim and desire to secure by Letters Patent is w In astereopticon of the class specified, the combination ofa continuously illuminated projecting device consisting of a 'contirnia ously illuminated lamp, a horizontally and vertically adjustable condenser, and a lens adjustable in the direction of said condenser, With' movable transparency holders arranged to contain transparencies and to pcprojecting device, said transparency-holder consisting of a'wheel composed of a hubnnd a plurality of radial 'arms'attached to said sition the same in projective register in said hub, each carrying a transparency-holder at v its outer end, a shaft in said hub for revolubly inounting's'aid ,Wheel, pins, corresponding in number to the number of said arms and holders,projecting horizontally from said hub, a revolubleshaft arranged with its axis in aline nentfwith the axis of said firstdisclaim such combination as is therein set G. FELT.
