Patented Dec. 19, 1939 UNITED STATES PATENT OFFICE Application March 11,

8 Claims.

The invention relates to display signs of the animated type, that is a sign in which a series of co-related pictures or cartoons are intermittently displayed. The present invention contemplates improvements and changes in that type of sign shown in my prior Patent No. 2,132,970 dated October 11, 1938.

As the display sign is primarily intended for outdoor use, is built of a substantial size and must run continuously without an attendant it is essential the parts be simple and rugged in construction, particularly the driving elements. One of the principal objects of the invention is to provide a drive which is of long life, practically cannot get out of order and which will accurately position the display panel in the opening through which it is viewed.

Numerous other objects will become apparent as this specification proceeds. Referring to the drawings forming a part thereof and in which a preferred embodiment of the invention is illustrated:

-Fig. 1 is a front elevation;

Fig. 2 is an end view part of the casing being shown diagrammatically in section;

Fig. 3 is an elevational sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a fragmentary sectional plan view taken on line 44 of Fig. 2;.

Fig. 5 is a fragmentary sectional View taken on line 5-5 of Fig. 4, the panel being shown in display position;

Fig. 6 is a fragmentary perspective view of the drive; and

Fig. 7 is a fragmentary perspective view of the fabric driving belt.

Referring again to the drawings, parts of the structural work supporting the sign are more or less schematically indicated but numerous other parts are omitted as forming no part of the invention and for simplicity of illustration.

The main supporting frame is generally indicated by the reference numeral l0. Secured in any conventional or convenient manner to the supporting frame is the casing ll diagrammatically shown in Figs. 2 and 5 and this casing is provided with a display opening l2 through which one of the panels, hereinafter described, may be viewed.

The sign proper comprises a series of panels I 5. These panels may be rigid in construction or may be formed of a flexible or semi-flexible material such, for instance, as heavy canvas. Unless the material from which the panels are formed is very substantial it is desirable to weight them at their lower edges, as indicated at Hi. The upper edges of the panels are secured in any desired manner to supporting rods I1.

The supporting rods l1 extend beyond the sides 1939, Serial No. 261,189

of the panels and are preferably provided with ends I8 of smaller diameter than the rods proper. The ends of the supporting rods engage plates which are continuous for the entire circuit of travel for the panels and prevent any endways or lateral movement of the panels and their supporting rods.

Guides are provided for the ends of the supporting rods throughout the larger part of their course of travel. The guides comprise tracks 2! secured adjacent the front edges of the plates 20, other tracks 22 secured adjacent the rear edges of the plate 20, and gravity tracks 23 connecting the front and rear tracks (see Fig. 3). The panels at all times maintain a vertical position and the tracks prevent any substantial forward or rearward displacement of the panels.

It has been found with the use of ordinary sprockets and chains that in operating the sign there is a tendency of the chains to jump the sprockets thus causing damage and putting the mechanism temporarily out of commission. A novel form of driving belt has been devised to which the ends it of the supporting rods are secured. This belt is generally indicated by the reference numeral 25 and as seen particularly in Fig. 7 comprises two strips 26 of fabric such as heavy canvas or other suitable material. The strips of fabric are folded over on themselves and at equally spaced intervals cross-strips 2'! of hard wood, metal or composition are secured in place by rivets or other means 28. The layers of fabric are preferably sewed together between the cross-strips as indicated at 29.

As particularly shown in Fig. 6 the ends it of the supporting rods are secured to the fabric sprocket belt by clips 30. If desired, the ends 18 0f the supporting rods may displace one of the cross-strips 2?. In addition the ends of the supporting rods are secured to metal sprocket chains 3|. These sprocket chains are the same length as the belts 25 and act as spacers to maintain the exact distance between the rods if the fabric belts should stretch slightly, thus insuring the accurate positioning of the panels in the display openlng.

The fabric sprocket belts are driven by sprocketc 35 formed on drums 36 which are mounted on short shafts 3'! having suitable bearings in the upper part of the frame. The teeth on the sprockets are tapered and are of substantial size to engage the large openings in the fabric belt and may be formed of hard wood suitably attached to the drums 3E. The teeth 35 being tapered on all sides will readily mesh with the large openings in the fabric belt and the possibility of the belt jumping the sprockets is practically eliminated. The surface of the drums 36 is substantially tangent to the rear track 22 so that as the ends of the panel support rods leave the sprockets they will readily enter the guides.

Idler drums or rollers 38 are positioned in the upper forward part of the housing and their surfaces are substantially tangent to the front guides 2| so that as the ends of the supporting rods leave the guides they will pass over the idler rollers. The sprocket chains 3| pass idly over the drums 36-3i5 and 3838. It will be noted the entire inside of the housing is open so as to provide a clear space and permit the panels to pass from the front of the housing to the rear and maintain their vertical position without interference.

The shafts 3'! have mounted thereon sprockets st lil which are connected by sprocket chains 4l-fil to sprockets i2l2 on a countershaft 43. The countershaft 33 is a driven shaft and, as shown in Fig. 2, is mounted in the rear of the housing. It is obviously essential that both sides of the panels be driven at exactly the same speed and that as the shafts 31-37 cannot extend across the housing the foregoing construction provides a simple means of synchronizing the drive on both sides of the machine.

The countershaft 43 is intermittently driven and the means for accomplishing this may be widely varied. As illustrated, the countershaf't 43 has a sprocket M mounted thereon and a sprocket chain 45 passes over this sprocket and another sprocket E6 which is intermittently driven by suitable mechanism mounted in the housing 4?.

The housing is provided with a wind shield 59, see Figs. 1 and 5, which is substantially the same area as the display opening l2. As the structure is primarily for outdoor use and the panels are of a substantial size the wind shield plays an important part in acting as a backing for the panels in their display position and insuring against damage by the elements.

In lieu of the canvas sprocket belt a sprocket chain having links with large openings might be used. In this event the spacer sprocket chains 3! might be eliminated.

Changes in details of construction and arrangements of parts such as would occur to one skilled in the art are to be considered as coming within the spirit of the invention as defined in the appended claims.
