SIGNAL FOR MOTOR CARS.

The object of this invention is to provide a signal by the use of which the driver of a motor car may indicate a left hand turn, the construction also being adapted for use in other types of signals.

A further object is to provide a device which shall include a plurality of relatively movable tubular elements, one of which shall be mounted on the dash board of a car, and the other of which is movable outwardly, at the will of the driver, the movable element carrying a signal such as a flag, and also carrying a lamp for use at night.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawings forming part of this application,

Figure 1 shows the device in elevation, as applied to a windshield, or the frame thereof.

Figure 2 is a further view in elevation showing the outwardly movable arm in inoperative position.

Figure 3 is a view of the device in longitudinal section.

Figure 4 shows the inner movable element in longitudinal section.

Figure 5 is a detail view showing a mounting device.

The main or outer tube 10 is mounted adjacent to the windshield, on the inner or outer side thereof, and projects slightly as shown in Figures 1 and 2, mounting means such as a clamp being designated 12. The inner slidable element 13 is also tubular and carries a signal of suitable form, such as a flag 14 carrying the words Left turn, it being understool that other forms of signals may be carried by the movable element of the device. A lamp 15, preferably having a red globe, is mounted at the outer end of tube 13 and is energized thru suitable conductors referred to below.

Tube 10 may comprise two sections, the outer section being designated 10, and being connected with the inner section by means of a T-coupling, such as 18, this coupling having threaded connection with the ad jacent ends of tube members 10 and 10. The lower tubular connection 19 of T-coupling 18 provides for the passage of a core 20 carrying a ring 21 at the lower end thereof,

the point 13.

the cord permitting of the operation of the movable element of the signal by the operator of the car, and the cord being of such length that both hands may grasp the wheel during the operation of the signal, so that full control of the vehicle may be retained in making the turn. Cord 20 is shown as passing around inner tubular member 13, and as having connection with the latter at Element 13 is normally housed within tube 10, being retained therein by means of tension spring 23 having its opposite ends secured at 24 and 25, the latter point of connection being on screw plug 26 constituting a closing element for the end of the tube.

In order to provide for necessary electrical connection for the lamp, I employ a socket 28 proportioned to fit within tube 13, this socket including the terminals 29 adapted to cooperate with lamp terminals 30. lVires 31 and 32 are connected with terminals 29, and are connected respectively with conducting rings 33 and 34, these rings being mounted in insulation 35, a body of insulation being interposed between two sections of tube 13.

When the signal is in normal, that is inoperative, position, t-he conducting rings 33 and 34 are in the position of Figure 3, but when the signal is thrown outwardly, rings 33 and 34 are opposite contact elements 36 and 37 and current flows thru a circuit c01npleted thru wires 38 and 39. Another form of clamping device is designated 40, and is illustrated in Figure 5.

Having thus described my invention, I claim:

A device of the class described, comprising a tubular element formed in two aligned sections, a coupling connecting the sections, said coupling having an outlet connection, a second tubular element operating within that first named, a signal carried by the second tubular element, a flexible device extending thru the outlet connection of the coupling and having connection with the second tubular element at a point near its inner end, and a spring connected with the inner end of the second tubular element and secured at a point near the inner end of the tubular element first named.

In testimony whereof I affix my signature.

THOMAS J. OLEARY.
