OPERATING MECHANISM FOR SIGNALING APPARATUS.

Specification of Letters Patent.

Patented Mar. 25, 1919.

Application filed April 2, 1917. Serial No. 159,083.

To all whom it may concern Be it known that I, FRANK ALDRICH, a citizen of the United States, residing at Highland-Park, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Operating Mechanism for Signaling Apparatus, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to signaling apparatus for automobiles and an object of my improvements is to secure simplicity, cheapness and adaptability to existing structures in this kind of apparatus.

I secure this object in the device illustrated in the accompanying drawing in which:

Figure 1 is a side elevation of the body and chassis of an automobile partly broken away to show the interior construction with an apparatus embodying my invention attached thereto.

Fig. 2 is a rear elevation of the same.

Fig. 3 is a detail sectional view showing the parts on a larger scale and Fig. 3 is a detail cross section of the actuating arm.

Fig. 4 is a sectional view similar to Fig. 3 showing the parts in a different position.

Fig. 5 shows a modification of my invention.

Fig. 6 is a detail sectional view showing the adjustable bearing for the oscillating shaft.

a is the body as a whole, (1, indicates the back and rear seat or the rear surface of the body. a is the heel board below the front seat. Upon the back a of the rear seat I provide a surface I) which may be of bright nickel plate Or may be white color to make a distinct contrast to the rest of the back of the seat. This surface is preferably circular and about the relative size shown.

0 is a shaft extending horizontally through the back a of the body beneath the rear seat and resting and adapted to oscillate in a bearing in the rear wall of the body. A metal sleeve 50 having a flange m at its outer end and screw-threaded at its inner end passes through the back wall of the body and forms a bearing for the shaft 0. There is a nut m upon the inner end of said sleeve and a washer a" of Wood or other suitable material between the nut and wall. Upon the outer end of the shaft 0 is rigidly secured an arm d having a disk (Z at its outer end and on the other end of said shaft is an arm 0 There is a spring secured to a stationary fastening at one end and to the outer end of the arm 0 at the other end and acting to turn the shaft 0 so that the arm d shall be at the lower limit of its travel and the disk d at its outer end shall cover the surface Z). The disk (Z is of the color and appearance of the rest of the surface of the rear wall of the automobile body.

Upon the heel board a I pivot a lever arm 9 by trunnions h h resting in bearings in a bracket f extending outward from said heel board. To the outer end of the arm 9 I secure a cord or chain j which passes over a series of pulleys i i 11 and at its other end is secured to the outer end of the arm 0 in such a way that a pull upon the cord j shall draw the arm a downward and raise the disk above the surface I) so as to expose said surface to the view of any one back of the automobile, to indicate that the automobile is about to stop or turn.

On the arm 9 I form a longitudinally extending slot g which slot extends into the arm past the axis of the trunnions h h. I secure the end of the cord 7" in said slot so that when the arm 9 is turned to its lower position, as shown, in Fig. 4, the cord j shall pass into said slot and beyond the axis of the trunnions it it so that the tension on said cord shall tend to .hold the lever g in its lower position with the surface 6 exposed to view.

In Fig. 5 a modified form of the apparatus embodying my invention is shown in which the bracket f extends from one of the bows 7c of the top and the cord j extends upward and along the top m of the vehicle.

It will be observed that the above apparatus is readily applicable to my form of automobile. That it is very simple and cheap to construct, is conveniently accessible to the driver and is in stable equilibrium in both of its operative positions.

Bell crank levers may of course be substituted for the pulleys over which the cord runs. As these are conventional alternative constructions no special description will be required.

What I claim is:

1. In an apparatus ofthe kind described, a. signaling apparatus, a pivoted lever, a cord connecting said lever at an eccentric point With said signaling apparatus, said signaling apparatus being adapted to produce a tension in said cord, the partsbeing so constructed and arranged that the cord shall pass beyond the pivotal point of the lever at one extremity of the throw of the latter, substantially as and for the purpose described.

2. In an apparatus of the kind described,

a signaling apparatus, a lever having a longitudinal groove in one of its surfaces,

a a cord connected to said signaling apparatus and to said'leiverwithin said groove, the parts .being so constructed that the cord shall pass into the groove and beyond the pivotal point of the lever at one extremity FRANK ALDRICH.

Copies of this patent may be obtained for five cents each, byladdressing the Commissioner .of Iatents, Washington, D. 0.
