To allwhom'itmayconcem: __. j ` Be it known that I, WILLIAM`
EDWARDY
residing- at Chicago, in the county ` _of.C'ook and State of-
Illinois, have 4invented new and useful Improvements in
Automobile-- Horns, -of which'the'. following is _a full,y My
invention. relates to hornsor warning
signalsffor automobiles, and the like, adapt ed to be connected
with~- the exhaustport of theengine ormotor so that lwhen the gases
expelled vtherefrom pass across 'the reeds of said .horn a chord
will be~ sounded for the purpose lofa' warning. _. ' _ _ j ' _., '
_
It is the object of 'my invention to con-_ struct a signa-1_
horn in such a mannerthat lno matter how high the pressure maybe
in
gine the -reedsof the _horn will notbe caused to shriek,
butalwaysbe of a uniform pitch.'
It is also an object of my inventionv to arrange the* parts in
as economical a man
sirnply thatthe carbonized particles of com~
This I accomplish bythe means and in the manner hereinafter
fully described and as more particularly ~pointed out in the
