LIKE DEVICES" George Stanley Shaw, Wallasey, England Application February 18, 1936, Serial No. 64,593 In Great Britain March 13, 1935 3 Claims.

The present invention relates to a moving band for use with advertising devices or devices for projecting a continuously changing message of the type in which light passes through a band the parts of which are translucent and parts of which are opaque.

It is the object of the present invention to produce a band for use with light projection advertising or the like devices in which sections carrying one figure, letter or the like or a group of figures, letters or the like may be removed and replaced by other sections. Such replaceability of sections of the band renders it possible to alter the message or other indication at will.

' According to the present invention, a band for use with light projection or the like advertising devices is formed of a pair of carrier members which are spaced apart and adapted to support between them a plurality of interchangeable and detachable elements, eachconsisting of opaque material having cut-cut signs, letters or the like and having readily detachable f-astenings with the said carrier members. i

The invention is more particularly described which:

Figure 1 is a view in perspective and partly in section of one form of construction.

Figure 2 is a diagrammatic view of the device in use.

Figure 3 is a sectional plan view corresponding to Figure 2.

Figure 4 is a plan view of one of the carrier elements taken on the line AA of Figure 5.

Figure 5 is an elevation of part of the carriers with detachable letter or the like elements in place.

Figure 6 is a diagrammatic plan view of the elements assembled on the carriers.

Figures 7 and 8 are details of construction.

The advertising or the like sign comprising a casing I is adapted to support a driving spindle 2 driven by chain or the like means 3 from a main driving sprocket 4 in geared relationship 7 partly translucent material [1, forming display with reference to the accompanying drawings in letters or devices. Each of these sign elements consists of a piece of opaque flexible material having a letter or design punched out, therefrom, which piece of material is backed by a sheet of translucent gauze or the like 20. These letters ll. are assembled on the carrier chains 8, 9, by first threading the spindle l3 into the slots II, and then threading the spindle l4 into the axialslot i2 of the next link; the threading of the next spindle l3 into the slot ll of this link simultaneously locks the spindle M of the next sign element and prevents accidental displacement of this.

The sign elements consequently can be assembled each one locking the next by slackening the chain carrier elements 8, 9, or alternatively, one or all of the brackets l0 may be provided with means to lock the spindles l3, M, such for instance, as a set-screw l8 passing through the bracket and adapted to project across the slot in this, and thus'prevent accidentaldisplacement of the mushroom-headed spindle l2, l3, as the case may be, as shown in Figures 6, 7 and 8.

The brackets l0 are provided in considerable number so that sign elements 'I 1 of varying width can be accommodated on the carrier chains or elements 8, 9.

Any illuminating devices, such as banks of neon tubes I9 may be disposed behind the exposed run of the display elements I! supported by the carrier chains 8, 9, as shown in Figures 1, 2 and 3.

The device is particularly suitable for instance for mounting in a canopy over the entrance to a building as shown in Figures 2 and 3, where a display may be made on three open sides of the casing of the canopy as shown in Figure 3.

By this means it will be seen that a moving display sign is provided in which the message, advertisement or the like to be displayed as a moving sign can be rapidly interchanged at will without necessitating the punching or construc-- tion of a complete fresh endless band.

The invention is not restricted to assembling the display signs I! as an endless band, but these may be assembled on a band which is first reciprocated from right to left and then from left to right, and so forth.

Instead of a positive locking of the spindle ends l3, l4 into the slots of brackets, the brackets may be magnetized to hold the steel ends of the spindles upon them or in open slots thereon.

I declare that what I claim is:-

1. A display device comprising in combination a pair of endless flexible carrier elements, pairs of brackets disposed thereon at spaced intervals, a plurality of interchangeable display sign elements, fastenings on opposite ends of said display signelements engaging alternate brackets of a pair, so that the end of one display sign element always overlaps the end. of the next display sign element.

2. A display device comprising in combination a pair of endless flexible carrier elements, pairs of brackets disposed thereon at spaced intervals, a plurality of interchangeable flexible display sign elements, fastenings on opposite ends of said display sign elements engaging alternate brackets of a pair, so that the end of one'display sign engaging in a transverse slot in advance of the 10 pin on'the opposite end of the next sign element iengaging in a longitudinal slot of the same bracket.
