v UNITED STATES FRANK A. MATTKE, OF VERNON, CALIFORNIA.

DIRECTION INDICATOR FOR AUTOMOBILES.

Application filed November 26, 1921. Serial No. 518.080.

To all whom it may concern:

Be it known that I, FRANK A. Ma'r'riin, a citizen of the United States, residing at Vernon, in the county of Los Angeles and State of California, have invented new and useful Improvements in Direction Indicators for Automobiles, of which the following is a specification.

My invention relates to automobile signals, and a purpose of my invention is the provision of a signal of simple, durable and efficient construction which is adapted to be operated to clearly indicate the intentions of a driver of a vehicle.

I will describe two forms of signals each comprising means for projecting light of two colors and each embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings,

Figure l is a view showing in side elevation oi? one form of signal embodying my invention.

Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary view of a dash and side of a motor vehicle showing the signal of Fig. 1 in non-operating position.

Fig. t is an enlarged detail view of the clip shown in Fig. 3. v

Fig. 5 is a view showing a portion of the closed body of a vehicle slot-ted to accommodate, the signal shown in Fig. 1.

Fig. 6 is a view showing in side elevation another form of lamp adapted to be used in conjunction with the signal shown in Fig. 1.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawings, my invention, in its present embodiment, com prises a handle H bored longitudinally to receive a pair of conductors K which extend into one end of the handle as clearly shown in Fig. 1. The opposite end of the handle is constructed to accommodate an electric lamp socket S, and this socket contains the usual contacts which constitute the terminals of the conductors K. The socket S receives a nlug 'P provided with the usual contacts. This plug is held within the socket by the bayonet and slot connection shown. The plug P carries a socket S which receives a plug P carrying a lamp L. Similarly, the. plug P is retained within the socket S by the bayonet and slot connection shown. 7

A protecting cage designated at C is removably mounted in socket S by means of a collar A, and when in applied position it serves to protect the lamp L against injury. This cage is also designed for the purpose of sustaining a second lamp L within the cage and upon the handle H, and to this end the cage is formed with wire extensions E which, as shown in Fig. 2, are spot welded to the longitudinally disposed wires of the cage and are curved to form a seat adapted to receive a socket S The socket S receives and sustains the lamp L at one end. and also contains a. plug I at the other end. which is electrically connected to the plug 1" by means of the conductors K.

The supply of current to both of the lamps L and. L is controlled by a two-button switch IV contained within the handle H and interposed in the line of conductors K in a manner which will be understood by those skilled in the art.

In practice, the conductors K are adapted to be connected to a plug switch B located on the dash board D of a motor vehicle as illustrated in Fig. 3. The conductors K are of suflioient length to allow of the signal being moved to a point exteriorly of the body of the motor vehicle and to be held in the hand, so that when the operator moves his arm to give the usual direction signals, the illuminated lamps will clearly and visibly indicate the position of the arm. The globe of the lamp L is preferably colored green, and that of the lamp L is colored red.

hen the signal is not in use it is securely held on the vehicle. body V by means of a clip G secured to the body in the manner shown in Fig. 3. The construction of the clip is clearly shown in Fig. 4.

hen employing the signal on a motor vehicle having a closed body, the body V is formed with a slot T through which the signal can be extended and moved from a point interiorly of the body to the several indicating positions.

In Fig. 6 I have shown a lamp L adapted for use in conjunction with the cage (J and to be substituted for the lamps L and L. In this form of my invention the globe of the lamp L is painted green as indicated at 16 and red as indicated at 17. Vhen using the lamp with the cage C, the wire extension E are dispensed with to allow the insertion of the lamp into the cage.

Although I have herein shown and described only two forms of signals each embodying my invention, it is to be understood that various changes and modifications may he made hereinwithout departing from the spirit of the invention and the spirit and scope of the appended claim.

I claim as my invention: A direction signal for motor vehicles comprising a handle, a socket supported on the handle, a lamp received in the socket, a cage sl'istained 011 the socket, extensions formed on the cage, and a second socket supported on the extensions and disposed Within the cage. 7

In testimony whereof I have signed my name to this specification;

FRANK A. MATTKE .1
