Specification of Letters Patent. Patented Nov, 13, 1917;

Application filed June 27, 1917. Serial No. 177,226.

To all whom it may conoem: I

Be it known that I, CARL R. Known, a citizen of the .United States, residing at Oakland, in the county of Alameda and State of California, have invented 'certaln new and useful Improvements in Indicators, of which thefollowing is aspecification.

The present invention relates to improve- 1 ments in signals and particularlyito a type ofsign'al adapted for, positioning on a vehicle to warn the drivers or operators of other vehicles as to the intention of the operator displaying the signal to turn from a straight course or to stop.

The invention consists primarily in a construction employing a target having a substantially solidly colored face provided with colorless portions thereon adapted to be plainly visible when the target is at rest and to be apparently absorbed by the predom1- nating color portion on the rotation of the target to high speed.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in .the claims hereto appended; it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein Figure l is a view in plan of the preferred embodiment of my invention.

Fig. 2 is a view in side elevation, partly in section.

Fig. 3 is a view in elevation of the target at rest.

Fig. 4 is a view in elevation of the target when rotating.

Fig. 5 is a diagrammatic view of the electrical system for controlling the operation of the target.

Referring more particularly to the several views of the drawlngs, wherein like characters of references designate corresponding parts1 indicates a substantially rectangular casing adapted to inclose and protect suitable batteries 2 and on said casing rests a circular motor casing 3 in which is positioned a suitable electric motor 4. To the armature shaft 5 of said motor 4 and adapted to rotate therewith is a suitable annular target or disk 6, the peripheral. edges of which are protected from contact by the overhanging flanged rim 7.

The face of said disk is substantially solidly colored, preferably red, the said co1 ored portion being separated or divided into sectors 8 by radially disposed symmetrically arranged colorless portions or segments 9, preferably white. i

' The combined area of the colorless portion is approximately one-eighth of the area of the disk while the'remaining. seven-eighths is red in color; Thus when the disk is stationary, as in Fig. 3, the red surface is divided into sectors by a plurality of radiating white sectors or division portions which increase in breadth as they near the outer end of said disk 6, providing a partially colored disk which may be seen from a great distance.

On the rotation of the disk at high speed the colorless portions or segments are absorbed in the predominating color portion and the disk has an appearance of having a solidly red color.

Supported at the opposite side of the casing 1 and facing in a direction corresponding to that of the disk are the lamp casings 10 and 11 inclosing the respective lamps 12 and 13, the casing 10 and lamp 12 serving as, the usual vehicle tail lamp and the casing 11 and lamp 13 serving as a danger signal for ruse at night in connection with the opera tion of the disk or target.

The lamp 12 connects with the batteries 2 through the leads 14 and 15, and said motor connects with the batteries through the leads 16, 17 and 18, the lead 16 which extends from lead 14 being normally interrupted in its connection with the lead 17 by a switch 19 preferably of the two-button snap type, and which is positioned within convenient reach of the vehicle operator, as, for example, on the vehicle steering wheel 20.

The lamp 13 connects with the batteries through a lead 21 connecting with lead 17, and lead 22 connecting with lead 15, said lead 22 being adapted to be broken by a switch 23; thus it will be apparent that when switch 23 is in closed position the lamp 13 will remain lighted as long as said target is rotating, due to the closing of the switch 19. To enable the lamp 12 to be extinguished during the day, a switch 24 is positioned in lead 14 intermediate said battery and the intersection of lead 16 with lead 14. A suitable member 25 extending from the casing 1 enables the apparatus to be readily installed on a vehicle.

By my apparatus 1 have provided a signal of the target type which when stationary has one appearance and which when rotating presents a different appearance, owing to' the speed thereof, and have also provided in connection therewith a lamp preferably of a color similar to that of the disk, and which is designed to be illuminated at night during the operation or rotation of the disk or target. I have also provided a signal capable of being operated from the batteries now universally used on motor vehicles.

Having thus described my invention, what I claim as new and desire to protect by Let ters Patent is 1. A signaling device for vehicles, comprising a casing, an electrically operated motor carried thereby, a circular signal member mounted on the armature shaft of said motor and havinga colored face, a contrastsenting a solidly colored face when rotated.

2. A signal device for vehicles, comprising a casing, an electrically operated motor carried thereby, a circular signal member mounted on the armature shaft of said mo tor and having a colored face, a colorless portion on said face d1v1d1ng said colored portion into a plurality of segments and said colorless portion comprising a plurality of radially disposed symmetrically arranged outwardly tapering segments visible when said signal member is stationary and on the rotatmg of the same presentmg wlth the colored portiona solidly colored face.

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