Y

ln order to extinguish the light, the corl responding push rod 32 may be depressed which in turn will d-epress the corresponding arm 28, or 29, and elevate the corresponding release rod 18, or 19, which will carry the corresponding switch arm. 6 or 7 out of contact with the tongue 16 and into the clamp 17 by which it will be held until its corresponding magnet is again'energized.

Any number, or all, of the lights 2 and 3 may be illuminated either simultaneously, or

successively and they may be simultane-r ously extinguished by depressing the push rods 32. Y

When the rods 82 are released the springs 30, 31 will operate to return the release rods 18,19 to their original or inactive position. Y c

Y l have shown and described which l now consider the preferredform of the apparatus, this showing, however, constituting only an illustration of the principle of the invention. It is evident that mechanical changes may be made and equivalents substituted for the parts shown and I hereby reserve the right to make such. structural changes or inodilications as may be found desirable and as may be comprehended within the scope of the appended claims.

lVha-t I' claim is n 1. ln a signal device, a switch arm, pivotally mounted at one end, a pair of spaced switch tongues between which the switch arm works, the free end of one tongue being overturned and formed into a clamp adapted to engage and holdthe switch arm, a release rod arranged to actuate said arm into engaged relation with said clamp.

2. ln a signal device a switch comprising a pair of spaced parallel switch tongues, a

switch arm, said arm being pivotally mountl ed at one end and adapted to work between the corresponding tongues of said pair, means operatable against said arm to carry said arm out oi" contact with one tongue ofA said pair the free end olf the other tongue Yhaving an arcuate, flexible grip forming inea-ns to engage and hold the switch arin out of said contact.

In testimony whereof l have signed my ROBERT A. NEVVE.
