APPARATUS FOR PRODUCING SUCCESSlVELY-CHANGING PICTURES 0R ADVERTISEMENTS.

SPECIFICATION forming part of Letters Patent No. 617,244, dated January 3, 1899.

Application filed August 6, 1897. Rerial No. 647,346. (No model-l T0 rtZl whom it may concern.-

Be it known that I, CHARLES FOUGERAT, painter, of Lyons, in the Republic of France, have invented certain new and useful Improvements in Apparatus for Producing Successively-Ohanging Pictures or Advertisements, (patented in Great Britain November 6, 1897, No. 402 5) and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to apparatus for producing successively-changing pictures,drawings, advertisements, or the like, and has for its object to provide means whereby the exhibits may be changed from one to another in an extremely short interval of time, a peculiar bizarre effect being produced at each change.

To this end the apparatus consists of a plurality of sustaining devices of suitable form and construction appropriately mounted in a frame to form a screen. A band or hands of any suitable flexible material, such as canvas or the like, and carrying a plurality of pictures or other exhibits divided into sections is passed over the sustaining devices, the sections of the pictures being so disposed upon the flexible material that component parts of a complete picture will be displayed at the same time upon their respective sustaining devices, means being provided for operating the flexible material to simultane-' ously move the component sections of the different pictures into and out of position upon the sustaining devices.

The invention further consists in the details of construction hereinafter described and claimed.

In the accompanying drawing the figure is a diagrammatic sectional elevation of my improved apparatus.

Referring to the drawing, L represents the sustaining devices in the form of laths or boards of any suitable material, which compose a screen. These sustaining devices are appropriately mounted in aframe (not shown) at a distance apart sufficient to admit of two adjacent bands of the flexible material passing freely between them. In this instance a series of bands are provided, one for each sustaining device. The first band is wound upon a roller R and unwound from a roller S, or

vice versa, while the second and third bands are unwound from rollers S and S onto a seccond winding-roller R, or vice versa, and so 'on with all the bands, at Winding-roller being provided for every two bands. According to the height of the changing picture or advertisement to be shown a corresponding number of sustaining devices, and consequently also of bands, with their operating and winding devices similar to those just mentioned, may be employed. On each of these hands a component section of each of the pictures to be displayed is applied by painting or otherwise, so that each of the bands must be brought into operation to produce a complete picture or exhibit, and as each section of a band corresponding to the width of its sustaining device is painted or otherwise provided with part of a different exhibit to yield successive and complete pictures or exhibits by the combined simultaneous presentation of corresponding sections of all the bands it is obvious that an intermittent forward or backward rotation of the rollers toan extent sufficient to displace the canvas a Width corresponding to the width of a sustaining device will change the exhibit, it being possible to cause the whole of the exhibits to appear in succession.

The different rollers S S are provided with any suitable means for stretching the bands, such as weights 1),

On the shaft or journal of each roller R is keyed a worm-wheel r. A shaft X, carrying a series of endless screws V, is mounted vertically to engage all the worm-wheels r with said endless screws. By operating the shaft X mechanically or otherwise an equal rotary movement may be imparted to all the rollerssimultaneously. All the bands will thus be simultaneously displaced on the sustaining devices L in the directions indicated by the two sets of arrows in the drawing, thus producing at first a novel, original, and interesting optical illusion during the change of the exhibit by the-blurring of the pictorial or other sections until the latter have moved sulliciently toproduce another complete picture or exhibit.

The rotary motion of the rollers, which is shown as produced by endless screws, may of course be obtained by any other suitable mechanismsuch, for instance, as beveled gearing. There may be joined with the driving-gear of the rollers a regulator or register for always giving exactly the same displacement to all the bands in order that the fitting together of the different sections of the pictures or exhibits may always be perfect.

An ordinary commutator or other reversing device may be combined with the apparatus to enable the bands to be immediately and automatically returned as soon as they have presented their final exhibit by reversing the direction of rotation of the rollers. These inverse successive displacements of the bands forward and backward are each represented in the accompanying drawing by different arrows.

Attention is especially drawn to the fact that in my apparatus the component sections present an apparently unbroken surface, this being true even during the change of the exhibits, which constitutes an especially novel feature of the apparatus, as during the change of an exhibit the picture is blurred and produces by the mixture of colors a bizarre etfect,which by constantly varying constitutes one of the chief attractions of the apparatus. It may also be pointed out that by the employment of my apparatus itis possible to display a very large number of exhibits in a comparatively small space. It is to be understood that the width of the sections of the pictures may be varied as desired to suit the nature and dimensions of the changing pictures, advertisements, or the like which are to be shown.

Having thus described my invention, what I claim is- 1. In apparatus for producing successivelychanging pictures, designs, inscriptions or other exhibits, the combination of a plurality of laths L arranged in a single plane to form a screen, with small intervals between each lath, a corresponding number of flexible bands arranged one over each of said laths and bearing each a different section of each exhibit, a series of winding and tension rollers for said bands, a series of worm-wheels r keyed on the shafts or journals of said winding-rollers, and a single driving-shaft X carrying a series of endless screws V to engage said worm-wheels to impart an equal movement to all the winding-rollers simultaneously, substantially as hereinbefore described.

2. In an apparatus for producing successively-changing pictures or the like, the combination with a plurality of laths arranged in a single plane to form a screen of a corresponding number of flexible bands passed one over each of said laths, said bands carrying component sections of the various exhibits, a plurality of winding-rollers for moving said flexible bands and a single driving-shaft and means for transmitting from said shaft an equal movement simultaneously to all the winding-rollers to display conjointly the various sections of an exhibit, substantially as described.

3. Inapparatusforproducingsuccessivelychanging pictures, designs, inscriptions, or other exhibits, in which a plurality of laths are arranged in a single plane to form a screen with a corresponding number of flexible bands carrying sections of the exhibits passed one over each of said laths, the combination with the flexible bands, of a plurality of winding rollers R arranged one for every two adjacent bands, a series of tension-rollers S S arranged separately one for each of the remaining ends of the bands, a single driving-shaft, and means for transmitting from said shaft an equal movement simultaneously to all the winding-rollers,substantially as hereinbefore described.

4:. An apparatus for producing successively changing pictures, designs, inscriptions or other exhibits comprising the combination of a plurality of laths L arranged in a single plane to form a screen with small intervals between each lath, a corresponding number of flexible bands arranged one over each of said laths and bearing each a different section of each exhibit, a plurality of windingrollers R arranged one for every two adjacent bands, a series of tension-rollers S S arranged separately one for each of the remaining ends of the bands, a series of worm-wheels r keyed on the shafts or journals of said winding-rollers and a single driving-shaft X carrying a series of endless screws V to engage said worm-wheels to impart an equal movement to all the winding-rollers simultaneously, substantially as hereinbefore described and shown.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES FOUGERAT.
