Application filed January 17, 1911. Serial No. 603,130.

To 141/ i l/1.0m it WLIIII/ (mu-rm Be it known that it, in'riiifu PHIL, a eiiixen of the United States, residing in the borough of ivlnnhatt'an of the city of New fork, in the State of New York, have invented certain new and useful improvemerits in Hutiler Cub-Guts, of \vhieh the follouing is a speeifieution.

The objectof this invention to provide nieuns arranged in the. exhaust pipe oi an engine, such as a gas or hydrocarbon engine. whereby the exhaust gases may he. direetwt or exhausted without passing through the Illtlllltl'.

The invention (insists in the new and novel features o1" eonstrinaion and cone hinations of pa 'ts hereinafter set forth and claimed and relates particularly to improvements on the construction set forth and claimed in my application for Letters Peteni: filed April 13, lJlO, Seriui To. 5

In the accompanying tll't1\\llgb.'* l is a plan riew partly in section of my littprovcd niulller cut out. 2 represents a side elevation. in section.

The cutout 1 may he urrauge huust pipe between the pipe se nected to the engine and the section 33 connected to the mutiter. The euti'iut" is so cured by its respective ends t and 5 to the sections 2 and 3 respectively by any suitable means as the flanges 6 secured in place by suitable bolts 7.

The cutout comprises a centre-.1 or drum portion 8 and a. cutout bypass t which may he formed of a sepnratipieee seeu ed thereto by means 01' ll e bolts 10. Preferably the side Walls oi. the drum portion are llured re and project through suitable openings 7 ll: 19 formed in the sides of the drum. A

(rank or lever 20 is secured to one of said trunnions wherehy the valve may be raised 1 and towered and a helical pring 21 is sei cured to the other trunnion so as to normally hold the valve in position to close the hypass.

in normal operation, when the exhaust :gases are passing through the mufiler, the

valve remains in its closed position resting upon the sent 1?. lVhen, however, it is desired to direet the gases through the bypass, the with the cireunrferential valve seat 12 which causes the valve to he arranged at an acute tingle to the axis of the exhaust pipe, thereby directing the gases of explosion clownward and outward through the hy-pass. The diameter of the exhaust pipe section land of the inuiiler pipe. seetion 3 are approximately the same, but the crossseetionularea oi" the drum is considerably larger than the eross-seetional urea. of either of said pipes, so tin 1 no reeoitingr or eholirig action upon the gases is possihle. When the gases are heing directed from theexhaust. pipe through the try-puss they are. directed through an opening which is constantly increasing in area, since the area ot thenurrowest portion oi the passage, assuming the valve is in its raised positiolnlis greater than the crossseetional area. of the exhaust pipe. Theretore, in this position of the valve, any choking action upon the gases is impossible.

31y means of this construction I am enaided to provide a inutller cutout in which somewhat as at ll so as to prov ide a greater 1 cross-sectional area in the drum than in the adjacent sections 2 and 25 and the top oi said drum portion is provided with an inclined semi-circui'n'ferential valve seat 1" The hy-pass of the cutout has its axis arranged at an angle to the axis of the exhaust line and is provided at one end with a. horizontal socket or recess 14 transversely positioned with respect to the ar-zis of the exhaust. pipe, which forms a hearing for the cylindrical end 15 of a. valve 16. The hy-pu. is also provided wi" sniail inwnrdiy projecting ledge or huge I? iio eh ii-strides a seat for the at: re, the said titiu 1 or the the passage through the exhaust pipe is completely closed, but. in whirh choking ol' the exhaust gases is ahsohuely prevented j hy l' iiMm ot' the uniformly enlarged areas of the sueeessive Htt'tlUiiS of the exhaust pussae'e, Furthermore this construction provides means whereby the gases may he delien-ted gradually from their normal path by an int-lined surface instead ot having their motion arrested and their direetiou eoni plete y and suddenly changed. The cutout;

ran he easily and readily detaehed from the main line oi the exhaust pipe or access may he had to the valve without removing the cutout as a Whole merely by detaching the holts i0 wlrch secure the hy-pass to the drum,

It ohvious that the cutout may he cur-ed to the exhaust pipe in nuniher valve is raised into engagement.

ways Without using the bolts shown and that the of eiplosion may be directed from the lay-pass in any desired direction, and that various other changes Within the skill of the mechanic may be made in the construction herein shown Without departing from the spirit of the invention, provided the means set forth in the following claims he enployed. 10 I claim as my invention l. in a mulller cutout the combination with the exhaust pipe, of a drum secured in the line of said pipe, and having a circumferential inclined valve seat formed integral therewith, a lay-pass detachably secured to said drum and comnnlnicating therewith, a valve mounted on said bypass and normally engaging a seat provided on said bypass, and means for causin said valve to engage with said circumferential valve seat and completely close the passage through the exhaust pipe.

in a mui'lier cutout the combination with an exhaust pipe, a drum secured in line thereu 'ith, a bypass secured to said drum and having a larger cross-sectional area than the exhaust pipe, and means adapted to-he arranged at an angle to the normal path of the gases through said exhaust pipe. to deflect said gases into the oy-paes through a passage having a constantly increasing cross-sectirmal scribed. 3. in a mul'her cutout the combination with the exl'urust pipe, of drum in said ex haus't pipe in line therewith, a hy-pass se-. cured :11. an angle to said drunrand having a greater cross-sectional area than said drum, a valve adapted to seat'on the end of the hy-pass and close the same in its lowered position and to seat against the inner Wall of th drum and close the passage area substantially detherethrough in itsrraised position; said valve in its raised position being arranged the exhaust pipe, a circumferential inclined valve seat formed integral with said central section, a lay-pass secured to said central section and having a greater cross-sectional area than said central section, a valve adapted to engage said valve seat in the central section and completely close the passagethrough the exhaust pipe, whereby the exhaust gases may be deflected through a constantly enlarging passage.

5. A mutller cutout comprising a central section adapted to he detachably secured in an exhaust pipe line and having a circumferential internal flange integral; therewith i and gularly arranged with respect to the exhaust pipe line, a bypass pipefdolachahly secured at an angle to said central section and having its end forming a valve seat symmetrical with respect to said internal flange, a valve in said cutout adapted to engage said seat and close the by-pass in its lowered position and to engage said flange and-close thc'exhaust line in its raiscdpo- 'sition, said valve in its raised position lorun -1ng one wall of acontinuouspassage from the exhaust pipe vtothe'hy-pass oi agradu ally increasing cross-scctioual area.
