Application filed August 12, 1911. Serial No. 643,687.

To; all whom 'it mary concern.

Be it known that l, RA E. STUMP, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State ot' Ohio, have invented certain new and useful Improvements in Signal-Horns,

' ot' which the following is aspecilication.

My invention relates to improvements in signal horns, and is particularly designed and adapted for use as an exhaust blown signal horn for use in connection with automobiles, motor trucks, motor boats, and the like. lNhen used as an exhaust blown signal horn in connection with automobiles, the same isgpreferably connected to the exhaust pipe between the engine and the muffler, and when so used the improved horn is adapted to provide a combined signal horn and cutout valve, the rotary valve beingadapted to be movedfrom its normal or nondiverting position to either a fluid diverting cut-out position, or a fluid diverting horn sounding position, as desired.

The primary object of the invention is to provide a generally improved combined signal horn andcut-out valve of this class of exceedingly simple, cheap, and eticient construction, adapted to be readily connected to the exhaust pipe between the engine and the mnler. l

A. further object is to provide an exhaust blown signal horn having its parts arranged and combined whereby the same may be readily operated and reducing their tendency to sticlt or to become clogged or covered with soot or carbon to a minimum.

A `With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement,- a'nd combination of parts, hereinafter described, illustrated in one oits embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this' specification, Figure 1, is a top plan view of the improved signal horn and :asA

valve, the parts being shown in their normal or nondiverting positions, whereby the liuid or exhaust gases are passed directly into the mu'ler. Fig. 2, a side elevation-of the same. Fig. 3, a vertical longitudinal sectional-view taken on line 3-3 of Fig. 1 the parts being shown in their liuid diverting Whistle or horn sounding positions. Fig. 4, a cross sectional view taken on line 4--4 of Fig. 3. Fig. 5, a perspective yiew of the rotary valve detached. Fig. 6, a perspective View of the rotary hood detached.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

..lhe improved signal horn and valve comprises a two-part vilve and horn body 1,

terminating at its o posite ends in reducedpipe Dinlet and outlet portions 2, and 3, rcspectlvely, adapted to be suitably connected` to and to form a part of the exhaust pipe leading from the engine to the muliler, the two parts of the valve and horn body being provided with attaching Hanges 1a. The valve and horn body is provided with a whistle slot Al, and a crossinember or par' tition 5, interposed between and secured'to the attaching flanges l, by means ot attaching bolts and nuts G. The cross member 5, is provided with a centrally located iuid dischar e valve opening 7, and a tluid discharge ot 8, the latter being located at the rear of the whistle slot 1, and being adapted to discharge the operating fluid to the lip 4a, thereof for sounding the horn in a well known and understood manner.

As a means for openingand closing the fluid discharge opening 7, a rotary valve 9,

is provided, saidvalve being provided with oppositely extending wings adapted to ex.- tend on opposite' sides of the cross member 5, and being pvotally mounted upon a pivot bar or shaft 10, the latter being mounted in suitable bearings 11, formed betweenthe attaching lianges l, of the valve. and horn body l.

As a means for operating the rotary/valve 9, whereby the same may be th/rowh` into a ii-uid diverting cut-out position' or iiuid diverting horn sounding pos1tion,one end of the pivot pin or shaft 10, `.is provided with a crank arm' 12, connected to a wircor cable 13, leading to suitable operating mechanism, the other end of the cranklarm l12, being 'conneet/ed to a spring 14, whereby the rotary valve 9, will be returned to and will be normally held in its normal or nondiverting pdsition, as illustrated in Figs. l, and 2, of the drawings. l

` As a means for opening and closing the whistle 'slot 4, when the rotary valve 9, is

moved to its closed or nondiverting position or to its vopen or fluid diverting positions, respectively, a rotary hood15,'is pivotally mounted 4upon bearing lugs 16, of the horn body, said hood being provided with segmental sides forming tone modifying elements adapted to cooperate with the whistle slot 4, in controlling the pitch andv tone of the horn when the latter is being operated or sounded by the passage of the operating fluid or exhaust gases through the fluid Adischarge slot 8, leading to the lip 4, ofthe Whistle slot, as illustrated in Figs. 3, and 4, of the drawings.

As a means for simultaneously actuating slot taking over and coperating with a guide pin 19, carried upon one side of the hood 15, whereby the latter may be operated in an obvious manner. l

From the foregoing description, taken in connection WithA the accompanying drawings, the operation and advantages of my A invention Will be readily understood'.

Having thus described one of the embodiments of my invention, what I claim and ing cut-out position.

desire to secure by Letters Iatent' is,

1. In a signal horn and valve, a valve and horn body comprising tWo l parts, one vof which is provided With a whistle slot, a cross member provided with a valve opening and a fluid discharge slot leading to said Whistle slot, a rotary valve adapted to open and close said valve opening, and means for moving said rotary valve to a fluid diverting whistle sounding position or a fluid divert- 2. A signal horn, comprising a horn body provided with a Whistle slot, a cross member provided with a rotary valve and a fluid discharge slot leading to said Whistle slot, a rotary hood adapted to extend above and to open and close said Whistle slot, and connecting mechanismfor operating said rotary hood when said rotary valve is actuated.

3. In a signal horn' and valve, the combination lwith a horn-and valve body provided With a Whistle slot, a cross member having a slot, a cross member valve openingand a iiuid discharge slot and a rotary hood adapted to extend above and to open and and horn body, and connecting mechanism adapted to open and close said Whistle slot las said rotary valve is moved to its closed and open positions, respectively.d

4. In a signal horn and valve, avalve and horn body provided with a Whistle slot and comprising two parts each part consisting of a ianged body and a reduced pipe portion,- a cross member interposed between said anged bodies: and provided With a fluid discharge slot and a valve opening, and

a rotary valve adapted to open and close Isaid fluid discharge valvev opening and adapted to be moved to a liuid discharge cpt-out position'With respect to said Whistle s ot.

5. A signal horn, comprising a vtwopart valve and horn body provided With a Whistle provided with a valve opening and a fluid discharge slot leading to said Whistle-slot, arotary valve adapted to open and close said valve opening, and a rotary hood connected to said valve and adapted to open and close said whistle slot when said rotary valve is moved to its closed and open positions, respectively.

6. A signal horn, comprising a valve and horn body provided with a Whistle slot, a cross member provided with a liuid discharge slot leading to said Whistle .slot-, a rotary valve adapted to be moved to a liuid close said Whistle slot; of -a ro-` tary valve mounted in said valve opening'` diverting cut-out position-With respect to i said Whistle slot, and a hood connected to said rotary valve and adapted to open and extend above said Whistle slot When said rotary valve i'smoved to its iiuid diverting IRA E.
