/Niil rUNITED STATES PATltITll GFFIt/i* EXHUST-w" Application led April 2l,
To u?! whom it muy conce'm:
lle it-known that l, CHARLES L. Hnnenn, a Ycitizen. ot the United States, resiing at d hito lllutl's. in the county oitlenton and State of lVashington, have invented new and useful.Improvements in lCxliainst-Mutiers, of which the 'following is a specitica tion. i'
This invention relates to inulllers ior deadening the sound of the exhaust from engineer` the niulller hereinafter described being especially designed for nac on gasolene engines and beingr adapted to automatically provide un outlet for the exhaust in proportion 'to the .speed ol the engine and the amount ot.' exhaust gast-fs escaping therefrom.
lVitli `the above general object in View the invention consists in the novel construction,
combination and arrangement of parte as fully described,
the, oppossite end of the inulller body may be leit open as indicated at 3. The head is provided with a threaded opening l to reeeive. the threaded end of the exhaust pipe 5 leading from the engine to the moitier.
A\djacent to the head 2, the body of the niulller is fornied with an annular series of exhaust ports (3 which are adapted to be opened and closed b the cylindrical port closure face T ol a vi life 8 which is inonnted for reciprocatory 1noven'1entin the lnutller body. The valve 8 is provided with an inwardly odset-cylindrical portion 9 at the extreme edge oi which there is provided a stop flange l extending outwardly therefrom. Tn conjunction with the valve 8 l employ a reeiproeatilw piston 11 of hollow construction embodying a cylindrical outer wall l2 "which works in contact with the inner snrtace of the niutller body l and outside of and around the cylindrical wall i) of th valve. At its extreme edge, the-wall e' the piston is provided with an annular stop Specicaton of Letters Fate .'t..

i adapte-d to 'more a inedeterinined distance equal to the space between the stop thinge l0 and 'the shoul l before the piston will operate to incre the valve 9 v01' the nnrnose of uneonering the enh tust ports o.
f ille nuilller body at vided with a rini lil extending; inwardly and terininating in an inturned tlange lll thereby rearing a forms a seat the outer end of a coil spring; 16, the opposite end of which bears against the piston il. .Preferably die pis ton ll is rzbbeted a shown at l? to form a scat for the inner end of the spring 16 as clearly shown in gir. l; in this way the snr-irrer is held centrally within the lnntller body and prevented front working" in contact with the inner wall of the innliler body. The springl in acts to torce the Liston baci; to its initial position shown in Fig. l, causingthe slop shoulder i3 to operate against an annular shoulder S onthe alve, thereby forcing` the rali/'e back to its closed position. as shown in l `ig.l. in the outward moreinent of the fiston il, the aalvefv is moved by the piston until tile ports t3 are uncovered as shown in 3. The spring` lo may be of any suitable size and tension proportionate to the size the engine and the `pressure, oit' the. exhaust 4delivered therefrom. The construction above described provides for a .light and eliicient inutiler which will prac! tically inutile the noise of the exhaust from the engine and which will automatically ack connnodate itself to the pressure' of the cxhaast and liberate the saine accordingly.
I claim l., exhaust .moitier comprising a receiv ini,Y chamber lia-ving outlet ports, a valve adapted to open and close said ports, and an exhaust pressnreoperated piston adapted to shift said 7alvc.
