ABRAHAM STEINBERG, OF CHICAGO, ILLINOIS, ASSIGNOR TO KINETO MACHINE COMPANY, A CORPORATION OF ILLINOIS.

STEREOPTICON ADVERTISING-CLOCK.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed. January 25, 1915. Serial No. 4,244.

To all whom it may concern:

Be it known that I, ABRAHAM STEINBERG, a citizen of the United States,'and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stereopticon Advertising-Clooks, of which the following is a specification.

This invention relates to clocks in which stereopticon slides are used, with suitable lenses and lights, to project an advertisement on to a screen.

The object of this invention is to obtain a device of the kind named, by means of which a, plurality of-advertisements may be thrown onto a screen, curtain or wall, at determined intervals; said advertisements to be surrounded by the ordinary clock nuv merals;with the hands of the clock approaching, but not extending to, the center of the clock dial or face.

Further objects are to obtain a device of the kind named which will permit ready changing of the advertisements appearing on said curtain, etc., to obtain a device which is simple in construction, of few parts, not liable to get out of order, or break, and which does not require any considerable skill to operate it. a

In the drawings Figure 1 is a diagrammatic view, showing the relation of the frame and some of the operative parts of the device, to the stereopticon elements of the device. Fig. 2 is a rear elevation of the mechanism embodying the invention. Fig. 3 a side elevation of the same. Fig. 4: a front elevation thereof. Fig. 5 is a vertical sectional view of the rotating dial and advertising plate carrier. Fig. 6, is a vertical section, on an enlarged scale, of one of the pockets of the plate carrier, showing a dial and advertising plate, inserted in said pocket, (also in section). And Fig. 7 is an isometric view of a member of the frame.

A reference letter applied to designate a given part indicates said part throughout the several figures of the drawings, wherever the same appears.

A is a shell or case, B a light, C a condenser; and D a lens.

E is a frame which is removably contained in shell A, in the chamber thereof which is lettered a. Frame E comprises standards 6, e and member 6 Standards 6 are provided with the horizontal portions 6 which bring said standards from the rear to the front of the frame. Member 0 is provided with the horizontal parts 6* and c and is attached to standard 6 by rivets e.

' e is a horizontal bar of frame E.

F is the frame of the clock movement of the device, and is shown as provided with two springs, f, 7, one of which is intended to actuate the striking mechanism of said movement. Frame F is secured in frame F.

G is the minute hand shaft of the clock movement, and on the end of said shaft whichv ordinarily projects through the dial of the clock there is placed the hour hand sleeve g, which is indicated by brokenlines in Fig. 2. Gear wheels H, (on the hour hand sleeve), and M, (on the minute hand shaft), are substituted for the hands which are usually placed on said sleeve and shaft.

I is a stud which is secured on one of the members or standards 6 of frame F, and J is a gear wheel which is rotatably mounted on the end of said stud.

' K is a shaft one end of which is mounted in part c of the frame E, and the other end in aperture 70 on horizontal part c of said frame.

' L is a spring on shaft Z, which is mounted in frame F, and shaft K is turned, (turning the carrier mechanism of the device) by means of gears consisting of N, n, n and n which form a train from shaft Z to shaft K. The movement of said carrier mechanism is not continuous, and is controlled by an escapement which is presently described. While the carrier mechanism is stationary the advertisement is shown on the screen, curtain, or wall within the numerals of a clock dial.

0 and P, are geared rings, mounted on rollers Q, to turn freely.

O and P are hands of a clock which are secured to rings 0 and P, respectively, to extend in toward the center of said rings. A portion of said hands are shown on said screen, etc, to indicate the time.

S and T, respectively, are geared idlers, the teeth of which intermesh with the teeth on wheels H, M, and O, F, to transmit the rotation of said wheels M, H, to said wheels 0, P. Said idlers are loosely mounted on shaft K, to turn freely thereon.

The advertisements which are to be thrown on the screen, etc, are placed, (together with numerals which are arranged around the advertisements, as on a clock dial), on a glass or celluloid plate, in the same manner as stereopticon slides are so placed, and the plates are mounted on the carrier R and successively brought into position to be thrown, or projected onto a screen by the stereopticon element of the device. That is, said advertisements and numerals are brought in line with the focus of the light and lens, by the rotation of said carrier. The carrier, or carrying means for successivelv placing said advertisements in said position, consists of hub 7', which is rigidlv secured to shaft K, arms r which extend radially out from said hub, the tappets V and IV 011 said arms, the disk 7' and nut 1 and the escapement which determines when said carrier can be moved by spring L consists of the pivoted arm U having tables u, separated by space M and the gear wheel J which is provided with the wrist pin j fitting loosely in slot 10 The teeth of gear Wheel J intermesh with the teeth of gear Wheel M, and the revolutions which said wheel J will make in an hour is determined by the relative number of teeth in said wheels J and M. At each revolution of wheel J a tappet V and a tappet W will be permitted to pass through space or aperture M and in the intervals between said passing of said tappets through said space an advertisement will be projected on the screen.

It will be observed that the tappets V are at a greater distance from shaft K than are the tappets \V, hence, when a space a is in position for a tappet of the V series to pass therethrough a tappet of the WV series will strike on a table t0, and when a tappet of the W series can pass through said space the succeeding tappet, being of the V series, will strike a table to.

X are pockets on plate R and Y are advertising plates in said pockets.

Z are buttons by means of which plates Y are secured in pockets X.

The several plates Y may be changed by turning the buttons Z one quarter around from the position in which they are illustrated in Fig. 2; but I consider the better way to be to remove the nut 1' and disk r from hub 7', and to then remove the plate R from the carrier R, before chang ing said plates.

The purpose of disk 1 is to hold the plate R closely to radial arms r thus insuring a good focus to the several plates as the same are projected on the screen, etc.

The operation ofthe device is: The clock spring being wound and'the clock started, the wheels H, M, and J, and the rings 0 and P, continuously rotate. An advertising plate and so much of hands O and P as are within the periphery of the advertising plate being in position to be'projected on a screen, etc, the light B is turned on, the advertising plate is focused on said screen, and said portions of said moving hands are also (being nearly in focus) projected onto said screen with said plate. Lever U is continuously swinging, and as the space a is brought into position for a tappet (V or IV) to pass therethrough, spring L will move the carrier It and plate B so that the next advertising plate, (with clock numerals thereon) will turn into position to be projected on the screen.

In the device illustrated eightadvertising plates will be projected on the screen in an hour. I have constructed and operated a device in which six advertisements are projected on a screen in an hour; and any reasonable number of said plates may be placed in a corresponding number of pockets (X) on plate R by merely having the arms 0 and tappets V, W, correspond in number with said pockets.

I claim:

1. A rotatable plate carrier comprising a hub and radial arms extending out from said hub and tappets on said arms, alternate ones of said tappets being at substantially the same distance from said hubs, and adjacent tappets being at a diiferent distance, tables spaced from each other, means to rotate said carrier and means to move said tables to permit a tappet on one thereof to pass through said space, transparent plates adapted to be attached to said carrier and stereopticon means to project said plates.

2.
