Another object of the invention is the provision,

of a signal adapted to be secured to the car door and arranged so that it will fold into the space between the inner panel and outer wall of the car door to be entirely concealed. V

Another object of the invention is the provision of a signal which can be actuated to either operative or inoperative position by a single flick of the hand. I

Another object which I have in view is the provision of a signal in combination with a clip which releasably holds the signal in either its operative or. its inoperative position.

Another object of the invention is the provision of a signal arm of very thin metal construction so that it will pass readily through a narrow slot in the outer wall of the car door, the signal being provided with a plate to entirely conceal the slot when the signal is in its inoperative position.

Having in view these objects and others which will be pointed out in the following description, I will now refer to the drawing, in which Figure l is a view in cross section of the car door showing the signal in its operative position.

Figure 2 is a view similar to Figure 1 but showing the signal in its inoperative position.

Figure 3 is a View in perspective of the signal.

member.

Figure 4 is a perspective view showing the signal plate I0 terminating at its inner end in a hook-like member I I which is formed by cutting an arcuate slot in the plate. A lever arm. I2 projects from the lower edge of the signal plate 'I I] and this lever arm terminates in a handle I3. The signal plate II] and the lever arm I2 are further comiected by a brace I 4. The parts II],

II, I2, I3 and I4 are integral and they may be,

struck out of ae'single sheetof metal.. For conwenience' the handle I3 may be-Lrounded. I The plate'Iiis-secured to the signal-plate W at-" its upperf'edge' and-transverselythereto so that the Jendel'evatiorr or transversersection' of the parts Wands IiwillabeiT-shaped {in- .outline.'-.

'As shown in Figures 1 and 2 the signal plat IE! is mounted to swing about a pin I6 which is secured to the outer wall orthe car door, the

securing means being shown in Figure 4. The car door is provided with avery narrow slit to permit the passage of the signal plate I0, and

the pin I6 is positioned across the slit and spaced inwardly therefrom. Two brackets I! are there- 'iore secured to the outer wall of the car door so as to project slightly into the space within the car door. Because of l the arcuate slot the signal plate In it is an easy matter to engage the signal plate In with the pin I6 as shown in Figures 1 and 2. When the signal is in its in- 20 operative position as shown in Figure 2 the plate I5 covers andconceals the slit and preventsthe entrance of water and. dust or other foreign matter. 7

The inner panel of the car dooris provided with a slot for the movement of the lever arm I2.

Adjacent the slot of the inner panel of the car.

door is a clip I8 as shown in Figures 5 and 6.

This clip is preferably formed from resilient 1 metal which is twisted into two half turns with projections or bends I9 extending part way across the slot as shown in Figure 5.- As shown in full lines in that figure the lever arm I2 is in its lowermost position with the signal in its operative position. The lever arm I2 is yieldably held in its lowermost position by the lower of the two bends A slight push upwardly of the handle I3 will cause the lever arm I2 to ride over the lower bend I9 and then over the upper bend I9 to its dotted line position in Figure 5 in which the signal will be in its inoperative position as shown in Figure 2. v The clip I8 is highly resilient and move the signal from either position to the other andit is only fora moment that the driver releases his left hand from the steering wheel. It is necessary, however, to selectsuch a position as not to interfere with the sliding windows 2 r w 7 ofothe car nor with the door lock or latch. The installationthus necessarily depends to some ex-' tent on the car construction'but the arrangement which I show in my drawing is adapted for installation in practicallyevery typeof closed car.

7 others skilled in the art to which it pertains,

what I claim as new and desire to secure by Let ters Patent of the United States is: s f I 1. In combination, an automobile door -having spaced apart inner and outer walls each pro-' vided witha vertical slot, a -pivot p'in'se'cured to said outer wall and spaced inwardlyatherefrom and transversely of the slot thereof, a signal arm having an open ended arcuate slot at its inner or upper extremity for 'releas'ably engaging 'said pivot pin; an arcuate lever projecting from said signal arm and through the slot of said inner wall, and a spring cliplsecured to saidxinner :lwall inside said automobile door; said springcliphavv a ing a pair of stops defining the operative and inoperative positions of said signal arm.

1 2. In combination, an automobile door having spaced apart inner and outer walls with a hollow space therebetween; said walls being each providedwith a vertical slot, a signal arm having a width materially less than the distance between said outer and inner walls, a pivot pin secured to said outer wall and spaced inwardly therefrom adjacent the upper, extremity of the slot of fsa'id outer wall, said signal arm being provided with an open ended arcuate slot at its inneror upper extremity for releasable engagement "with said pivot pin, a transversely positioned plate on said signal arm, said plate having substantially the dimensions of the slot of said o'iiter wall whereby said plate will be continuou'swith said outer wall when said signal arm is in inoperative position, an arcuate lever proj'ecting from said signal'arm and. through the slot ofsaid inner. Wall,,and a spring'clip secured to said inner wall at the'inner side thereof, said spring clip having, apairof stops for defining V the operative andin'operative positions of said signal arm.
