IILOVING SIGN.

Application led December 2, 1911.

ica, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful improvements in Moving Signs; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in moving signs and its object is to provide a device which will present a large amount of display surface, to provide a sign well adapted to attract attention, to provide an improved changeable sign, and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims.

This device consists essentially of a bracket adapted to be attached to the wall of a building or like support this bracket having an oscillatory shaft journaled therein and a triangular sign having three vertical planes mounted on the oscillatory shaft at one of its substantially equal vertical angles and adapted to shift the direction of the surfaces of its panels, and more effectually attract the attention of a passerby by this swinging movement.

This device is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my newly invented moving sign; Fig. 2 is aside elevation of the same with parts broken away; Figs. 3 and e are enlarged sectional details of the lower end of the oscillating shaft showing the operating mechanism; and Fig. 5 is an enlarged detail of the gearing viewed from the opposite side from that shown in Fig. 2.

Like numbers refer to like parts in all of the gures.

1 is a bracket adapted to be attached to any convenient support and provided with journal bearings 2 in which is preferably mounted a vertical oscillatory shaft 3. This shaft carries the sign which in the accompanying drawings is shown as made up of three rectangular panels i joined together at their respective edges to form an equilateral triangular prism having substantially equal vertical sides, the shaft 3 being attached near one vertical edge of this prism. The lower edge of the shaft 3 is Specification of Letters Patent.

provided with a bevel pinion 5 which meshes with the segmental bevel gear 6 mounted on a transversely extending rock shaft 7 which is also journaled on the frame or bracket 1 An arm 3 is fixed on the opposite end of the rock shaft 7 by which the said rock shaft is actuated. A crank wheel 10 is j ournaled on the shaft 7 and a crankpin 11 projects from its face and is eccentrically located thereon and also radially adjustable in a slot 12 in the wheel. A rod 9 connectsthe crank pin 11 with the arm 8 on-the rock shaft and as the disk 12 rotates it imparts a reciprocating movement to the arm 9.

The crank wheel 10 may be rotated by any convenient mechanism. ln the accomanying drawings I have shown a motor 13 attached to the bracket and a train of gears 14, 15, 16, and 17 driven bythe motor to rotate the said wheel. lt will be seen that as the wheel rotates driven by the motor through the train of gears, the connecting rod 9 will be given a reciprocating movement which will rock the shaft 7 by means of the arm 8 and cause the segmental bevel gear 6 to oscillate. This oscillatory movement will be transferred to the vertical shaft 3 through the bevel pinion 5 thus causing the display panels at which are mounted on the shaft 3 to assume a swinging movement.

The radial adjustment of the crank pin 11 enables the stroke of the connecting rod to be varied thus changing the arc through which the sign travels in the swinging movement.

Tt is obvious that any other form of m0- tive power may be applied to this device to produce the same result. The advantages of this device are that a considerable display surface is obtained in comparison with the outward projection of the device, each surface of the sign being visible from various points of view during the cycle of operation. This is particularly desirable in cities where the city ordinances limit the projection of a display device within certain dimensions. This sign will also by virtue of its continuous movement attract the attention of a passerby where a stationary sign would fail to do so.

What l claim is 1. An oscillatory sign including in combination a bracket, upper and lower journal bearings secured to and extending outwardly from the bracket, a vertical shaft journaled iii said bearings, a horizontally disposed rock shaft jouriialeil' in the lower bearing, a triangular prism having three vertical plane sides and along one of its verw` A*ical edges secured to said vertical shaft, a beveled pinion secured to said vertical shaft,- a segmental beveled gearfixed to the rock shaft to mesh with said beveled pinion on the vertical shaft, an arm on the rock shaft to actuate the samez to oscillate the vertical shaft and swingingly osci'llate said triangular prism, and means t0v operate said arm. y 2. An oscillatory sign including iii' combi'- nation a bracket, upper and lower journal bearings secured to and extending outwardly from the` bracket, a vertical shaft journaled in: saidbearings, a horizontally disposed rock shaft journaled in said lower bearing, vertical plane sides and along one of its vertical edges tical shaft, a beveled Vcons three vertical Vplanes mounted on saidv y sliaft atA oneJ of its vertical edges, and means for oscillz'itin'gv the shaft to swingvthe trian-4 vgularpr'is'ifii backwardly and forwardly on l opposite sides ofthe vertical, shaft A and away from said bracket.I

a triangular prism having three y securedV to said ven' j pinion secured to said ,1 vertical shaft, a segmental beveled gearl fixed to the rock shaft to mesh with said i beveled pinion on the lvertical shaft, an I arm' on' the rock shaft to actuate the same to oscillate said rectangular prism, and means carried by the bracket and operatively coni nected to said arni to actuate the latter.

3. An oscillatory sign including in combination a bracket, upper and lower bear- .ings secured to and extending outwardly from said bracket, a vertically disposed oscillatoryshaft carried by said bearings and spaced from tli'e bracket, a display device of a triangular prism having' toward In testimony whereof I affix my signature iiipresenc'e of two' witnesses.
