it knowlithat LIRA E. STUMP; a /citii zen'of the .United States, residing at Cleveland, "in the county ofgCuyahoga and State of Ohio, have .invented certain new and useful Improvementsjin Valves 'andHorns, of;.whieh. the `following is' a specification.

' AMy .invention relates to improvements in' valvesiand-horns, and more particularly to a. combined cut-out. f. valve and signal horn, particularly designed and adapted for: use' Serfin connection with" the exhaust-pipe leading from.; afhydrocarbon engine to the 4muiier commonly employed" in .connection 'with automobiles, motor bo'ats,ffandv the like..

Under. 'ordinary circumstances when. the

. A,exhaust ris. forced@ directlyA to the Vmuiiier thereis considerable back pressure resulting- -iinsa certain loss-fof power by impeding'the action. of the motor, consequently, what are knownl asdcut-out?. valvesf are frequently provided whereby .the exhaust, may be permittedztdesoape directly through-the valve and. into the air, instead of through lthe muiiier.j ff .Y

VIn exhaust-valves`an lj hornsof this class, there isa'tendencv .of parts and ports to be# come covered and clogged with carbon in' the form of soot by the action ofthe exhaust gases, and the .primary object :of this invention istorprovide a generally-.improved coinbined cut-out v ve and si 'nal horn of g simple, vcheap,.and eiicient construction, in

which the several parts are so disposed, constructed, and arranged as to reduce the above mentioned tendency toY a minimum.

A further object ofthe invention is to provide a valve of this class, capable of receiv-v ingthe exhaust from hydrocarbon engines .and distributing the same either to the m'uier or `to another. point ofl discharge without producing an undue accumulation of back ressure. This point of discharge may be ireotly to the atmosphere through the -"cutout valve, proper, or indirectly thereto'through the signal horn or whistle portionthereof.

. With the 'above mentioned and other ob- -jectsin view, theinvention consists iin the novel construction, arrangement, and combilnation of parts, hereinafter described, illus- 'trated in one-lof its embodiments in the accompan'yingy drawings, c pointed out inthe appended claims.

and particularly i' Referring tothe drawings, .forming a part like parts 'tof this specification, Figure l, is a side elevationof the' improved t cut-out valve and` clearer illustrationof the'parts. 'Fig. 3,:.a

"i :2.: Similar numerals :.of reference. designate? hroughouit all the igures of the drawinos.v l The. improved valve and horn .comprises van exhaust-pi e or pipe' body.1,a.dapted toV lead to a m er in the usualmanner when the exhaust is from a hydrocarbonl enginei.. The exhaust-pipe or pipe body is provided at one sidewith a segmental whistle-slot 2, for utilizing the' operating fluid. or exhaust gases in sounding the horn, `as well as projvidi'n'g means for discharging directly into f the atmosphere through the cut-out valve as hereinafter described. f. 'As a-:means for diverting fthe operating fluid to the -whistle-slot 'for sounding the' horn in a well vknown and understood man..

ner, 4as 'well as diverting the' same from, the muffler, a valve-disk 3, isfrotatably mounted in the exhaust-pipe or pipe body inclose proximity' .to the whistle-slot, said valve- .disk being adapted to be moved' to an open position for permitting the exhaust gases to pass directly to the niuther as indicated in Fig. 2, oithe drawings, or to be moved to a transverse or Huid Adiverting position as 4indicated in Fig. 8, of the drawings, whereby the operating fluid, may be directed against the lip or edge 2a', of the'whistle-slot for. sounding the horn inawell known manner. The rotary valve disk is preferably provided with a peripheral recess o'r cut away portion 3, for providing an inlet slot or passageway for the'opelating fluid to the lip por. tionl ofthe whistle-slot, As a means for entire'y closing the whistle-slot whereby the exhaust gases may be conducted directly to the muiier,a valve' body or hood 4, is mounted upon the exhaust-pipe or pipe body above. the whistle-slot, in the present instance, by means of screws 5, said valve-body or hood being recessed at its sides and front -portion to provide a cut-out portopening 6, for the escape of exhaust gases as through Vthe whistle-slot as. hereinafter described. Asameansfor opening and closl` the latter pass out ing said cut-out port opening, as Well'as for. moving the valve-disk 3, to and from a iuid diverting position, a cut-out valve 7, is

connected to the valve-disk, said connection consisting, in the: resent. instance, of an axle or bearing-sha 8, mounted in and extendin transversely through the pipe body, the va ve-disk being secured thereto in a suitable .manner as by means of a screw 8,

latter will be moved to and fromja' fluid di.

verting position When said cut-out valve is moved to its open and closed position, respectively, as indicated in tlie` drawings. The .cut-out valve 7 is provided with per` forated ears or lugs 7b, whereby arcoil spring 9, and connecting cord 10, may`beconnected,

f said coil spring being adapted to normally hold the cut-out, valve in a closed posi# tion as indicated in Fig. 1, of the drawings, and said connecting cord communicating 'with a foot lever (not shown) o r Otlierfsuitable means for moving the cut-out valve against the resistance of tlie coil spring 9.

When it is desired to move the parts for use as a cut-out valve, the valve V7, is mov'ed to the intermediate position indicated by' `dotted lines in Fig. 3, of the drawings,

-itbf'e'ing observed that if the valve 7, is

niot'fd to its extreme open position, the valve-disk 3, Will be moved toits transverse or Whistle sounding position as indicated in fulllines iii Figs. 3, and 4, of the drawings.

From the foregoing description, taken' in conpection with the accompanying drawings,

the operation and advantages of my invention will'be readily understood.

Having thus described lan embodiment of my invention, whatI cla' Y* and desire t-o secure by LettersfPatent is,- l

`1. In a valve and horn, a pipe body provided with a whistle-slot, avalve-disk'lrctatably mounted in' said pipe body, means for moving said valve-disk to various' positions, and means for closing said whistle-'slot when vertingfposition. 2.' In.; a valve and horn, -a pipe'body provided With a Whistle slot, a rotatablymount ed valvesdisk provided with a peri heral recess adapted to form. a fluid inlet s otto the lip of saidavhistle-slot when said valve-disk is moved fda transverse fluid diverting posisaid valve-'disk has been moved to 'anondftion, mea-iis. for' closing said whistle slot when saidvalve-'disk ismoved to a. nondiverting position and means for moving said valve-disk to diverting and nondiverting positionswithn saidl ipe body.I

. 3. A valve and orn, comprising a pipe body provided with a. Whistle-slot, a rotary valve-disk mounted in said, pipebody and adapted to divert the operatin v4fluid to said whistle-slot, a hood, mounte above said `whistle-slot vand providedwith a pprt opening, and a cut-out valve coperating WlthA said hood normallyclosing said port open ing and connected' to and adapted to move said valve-disk to its whistle'sounding position when said cut-out valve is moved toits extreme open position.

In testimony whereof I have aixed my signature, in presence of two Witnesses.
