‘ 11 Claims.
This invention relates to improvements in sig
naling devices for indicating changes in the di
rection of movement in‘ vehicles.
One object .of the invention is to provide a
5 signaling device that will be rendered operative
upon movement of the steering wheels of a ve
hicle out of their normal forward direction of
A further object is to provide a signaling device
10 of the character described which is operable by
means loosely engaging a. structural portion of
only one of the front or normal steering wheels
of the, vehicle.
Another object is the provision of an audible
:15 signal which is rendered operable by-one of the
front or steering wheels of a vehicle upon change
in direction of travel of the front wheels.
More speci?cally, the invention contemplates
an audible signaling device of the character de
wherein the clapper for a gong is moved
away from the gong by a trip member which is
engaged and actuated by an extension on a slid
able bar, which bar has a bifurcated end, with
the bifurcations engaging a structural portion of
25 the vehicle steering wheel at points fore and aft
of the axle for said wheel, the clapper being forc
ibly returned against the gong by a spring, upon
disengagement of said trip and the trip-actuat
ing means.
A further'object of the invention is to provide

member and its actuating element in the position
these parts occupy at a point just immediately
prior to their disengagement after the signal has
been operated.
The major portion of the device is enclosed in
a casing H] for protection against dust and other
foreign matter andsaid casing has a base H by
means of which the casing can be mountedupo-n
the front axle l2 of the vehicle. Mounted within :15
the casing is a gong l3 withwhich a clapper l4
cooperates, the clapper preferably being carried
.on an arm having a ?exible portion IS-and, a
substantially rigidv portion |6.---. Preferably the
latter is pivoted on a vshaft l1 and yieldingly :20

a stop H! which may be formed by a bracket
mounted upon a block 20 within thecasing. The

a cross-piece 26 having extensions at its opposite
ends adapted to engage a. structural portionv of
one of the wheels of. the vehicle at points in
