Application February 4,

Claims.

My invention relates to changeable electric light signs and refers particularly to devices of that character adapted for exhibiting a plurality of still figures, emblems or other desirable mat- 5 ter, as well as a plurality of designs, or figures,

so arranged as to give the impression of a movement of these designs or figures.

One of the objects of my invention is a device having a plurality of plates, each plate having a plurality of perforations arranged according to a predetermined design, and means whereby the perforated designs may be converted into corresponding electric light effects without movement being imparted to either the perforated plates or the contact carrying plates.

In the present known methods for producing a changeable electric light effect in signs and similar devices by means of perforated plates, either the perforated plates or the contact carrying plate, or means, are moved with respect to each other in order that consecutive contacts may be made with the perforated plates.

These devices having the above described movable means have many mechanical and commercial objections, among which the following may be mentioned: Thefnecessary movement of the perforated plates or the contact plates requires expensive and intricate mechanism resulting in costly equipment requiring constant expert 30 attention, and the impossibility of producing satisfactory motion picture light eiTects.

The same requirements are necessary in the production of motion picture light effects as are necessary in the screen projection of photographic motion pictures, that is, there must be a rapid succession of light effects of a continuity of progressive designs separated from each other by the absolute absence of light.

Unless the succession of light eflects is ,sufliciently rapid, there results a plurality of individual light impressions instead of a continuity of movements, thus producing a jerky series of 1 light effects instead of the impression of a ;con-,,

tinuous movement of the elements of the design; and unless there is complete non-illumination between the successive steps of illumination, the result has a blurredand indistinct appearance.

.These necessary elements incident to the ,production of an effective moving-picture by means of a plurality of electric lights are incapable of attainment by means of 'movable perforated plates and contact carrying plates, because it is impossible to move theplates with sufllcient speed and accuracy to accomplish the desired result.

, In my device the easily removable and replaceable perforated plates and the contact carrying plates are in fixed position with respect to each other, thus overcoming the necessity of complicated moving mechanism, and the make and break mechanism is accomplished by means of an electrical distributor comprising a simple revoluble element capable of as rapid operationas desired, and which is adapted to co-operate with any perforated plates which maybe employed without any alteration or change in the revoluble element. a r

The construction of my device is such as to fit it eminently for the production of either still or moving light effects, for if theplates represent a continuity of motion, the revoluble member may be revolved sufliciently rapidly to produce a motion effect; whereas, if the plates represent different and unconnected designs, the revoluble member may be revolved sufficiently slowly as to maintain each design in light effects for any predetermined period of time. I

The novelty of the device of my invention and the advantages incident to its employment will be evident upon a consideration of my specification and its accompanying drawings in which similar parts are designated by similar numerals.

Figure 1 of the accompanying drawings is a perspective front view of one form of the device of my invention, partly broken away for purposes of clearness of description.

Figure 2 is a bottom view of the plate pack shown in Figure l.

Figure 3 is a front edge view of the device of Figure 2.

Figure 4 is a section through the line l-t of Figure l.

Figure 5 is a section through the line 5-5 of Figure 2.

Figures 6 to 11, inclusive, are face views of the perforated plates shown in the accompanying drawings. v g 1 Figure 12 is a vertical cross-sectionof a modified form of platepack.

The particular form of the device of my invention illustrated in Figures Ito 11, inclusive, comprises ,a plate pack consisting of" a plurality of plates of electrical conducting material l5, l6,

l 1, 18,19, 20, separated from each other by sheets of insulating material 2 I, 2 l and havinga bottom sheet of insulating material 22. A plate of insulating material .23 somewhat larger than the plates, l5 to plate pack. a a g Each plate l5 to 20 has two extended tongues 20 is positioned upon t WP the 2,006,436 and breaks the circuit in the order of the consecutive movements, the electric light bulbs will show a plurality of individual illuminations producing the effect of a movement of that object.

It is further evident that if the plates I to 20 inclusive, carry independent perforated de vices, the cylinder 49 may be revolved sufficiently slowly to maintain each of the illuminated effects for a predetermined period of time.

It will thus be seen that my invention presents a device capable of producing still or motion electric light effects by means of removable and replaceable perforated plates and a contact carrying plate without movement of said plates, the designs represented by the perforated plates being produced in illuminated effects in any desired consecutive order and for any predetermined period of time respectively, and hence possesses many advantages and desirable attributes not found in other devices for the same purposes and, further, that my device is capable of producing effects not obtainable by other perforated plate devices.

By plate pack I mean a plurality of conductive plates separated from each other by insulating material, or otherwise, with a plurality of aligned holes therethrough and it is immaterial whether the planes of said plates are vertical, horizontal or otherwise, and hence I use the word superimposed in my claims to include all positions of the plate pack.

I do not limit myself to the particular size, shape, number, arrangement or material of parts as shown and described as these are given simply as a means for clearly describing the device of my invention.
