Application filed February 5, 1909. Serial No. 476,276.

To all whom it may concern.'

Be it known that I, HARRY Il. IVINTEES, residing at Sewickley, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or dis- -covered certain. new and useful Improvements in Mufflers, of which improvements the following is, a specification.

The invention described herein relates to certain improvements inI muftlers for gas engines, etc. Y

It is frequently the case that mulliers which will be effective to deaden the report of the exhaust without causing any detri-l outer wall of the mutlier where soot may be deposited; the gases then flow through orices into another chamber where the gases are again deliected outwardly to free them from the soot, `tc.

The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part 'of this specification, Figure l is a sectional elevation of my improved muilier; Figs. 2 and 3 are transverse sections von planes indicated by the lines II-II and III-IIL respectively, of Fig. 1. Fig. 4 shows an enlarged section and elevation showing the preferred arrangement of deflecting surfaces or abutments .and the perforations. Fig. 5 shows a reversed arrangement of the abutment and orifice; Fig. 6 shows views similar' to Fig. 4 illustrating a modication; Fig. 7 is a side elevation and Fig. 8 a sectional elevation illustrating av modification of my improvement.

In the practice of my invention, I employ a shell 1 preferably slightly tapering to facilitate the removal of parts for cleaning, and provided with heads 2 and 3. The 'smaller head 2 is adapted to be connected through a central nipple with the exhaust pipe and the larger head is provided with a plurality of openings preferably arranged adjacent to its periphery as indicated iu Fig. l. @ne or more hollow cones l are arranged within the shell with their apices pointing toward and in line or approximately inlinel 4with the axis of the port or opening 5 through which the exhaust enters the shell,

with a plurality of abutments or inclined surfaces 6 against which the gases lim-Jing along the surfaces of the cones will strike and be deliected outwardly away from the outer surfaces of the cones. The stream of gases liowing through the-port 5 will by inipact with the point of conc 4 be given an annular form which in the construction shown in Figs. l to (i is broken up, into fragmentary streams by the inclined abutments or surfaces 6 which as shown are so arranged that those of one row will alternate with those of adjacent rows. In addition to dividing the gases into streams the inclined surfaces direct the gases outwardly so that gases deflected by the abutments or surfaces 6 of the first cone will be directed against the inner Wall of the shell and soot, etc., carried by the, gases will be deposited on such wall.l As the angle of impact of the gases on the cones is small there will be little or no deposit of soot, etc., thereon and incase any such deposit should occur, the next volume of gaseswill sweep thelrrv away. From the chamber formed by the cone 4 and the shell of the muflier, the gases flow through openings 7 in the wall of the co'ue into the chamber formed by the cones 4, 4 and the shell of the muer.

These openings are pref-Y The outer surfaces of the cones are provided erably formed closely adjacent to the abut- Y ments or inclinedv surfaces 6. A convenient manner of forming the abutments, is by raising the metal of the cone at points where the abutments are to be formed as indicated in Figs. l, 4, 5 and 6. The openings 7 for the passage of the gases are preferably formed by so cutting the tops of the raised portions and then slightly lifting the tongue metal 8 thus formed. In the form shown in Fig. 6 a straight cut is made before the metal is'raised, so that an opening through the wall of the lcone will be formed in raising the metal to form the abutment or inclined surface. It will be observed that the tongues 8 will direct gases flowing through the opening 7 in a. direction at an acute angle to the surface of the next cone 4a or ll. which are similar in construction tothe cone 4: The inclined surfaces or abutments of the succeeding cones will also break up the gases carried thereby will he deposited against the inner wall of the preceding cone or of the shell l. The number of cones employed will depend upon the volume of gases in each exhaust or the horse power of the engine. It is preferred to terminate the series of cones with an Qppositely arranged flattened cone 9 provided with perforations for the escape of gases. This cone is also provided by pref erence withA abutments or inclined surfaces 10 .on its inner'wall the perforations being formed adjacent to the abutineiits as before described.

A dome shaped partition ll is preferably arranged between the cone 9 and the head 3, said partition having a diameter suliciently less thanthe internal diameter of the shell l, to provide an annular passage for the outward flow of the gases, as shown in Figs. 1 and 2.

While the several internal .parts may be detachably connected to the shell l, it is preferred to attach the cones to rods 1:2, which may be secured in place in any suitable inanner. In the construction shown one end of the rods project through the'head l 4and are threaded for the reception of the nuts 13. The upper ends oli the rods are held in place by bolts 14.

In lieu of detached abutments or inclinedsurfaces, peripherally continuous abutnients can be employed as shown in lFigs. 6 and 7. These continuous abutnients may be formed by so eorrugating thecones as to orin holhaving a closed apex pointing toward and adjacent to the inlet, the cone being provided on its outer Wall with abutments shaped outwardly to detlct gases flowing along the cone, and means permitting the' escape of gases beyond the cone to the outlet.

2. An exhaust mufllerhavin'g in Icombination a shell provided with an inlet and outy sedici along'the cone and having perlioi'ations for the tlow ot gas into the interior olf the cone.

3. An exhaust muffler having in combination a shell provided with an inlet and outlet, a hollow cone arranged within the shell having a closedl apex pointing toward and adjacent to the inlet, portions of the outer surface of the cone being raised to form delecting abutineiits, said abutments having openings therethrough for the passage ot gases to the interior of the cone.

l. An exhaust mutller having in conibination a vshell provided with an inlet and an outlet and a hollow cone arranged within the shell having a`closed apen pointing toward and adjacent to the inlet; portions oif the outer surface of the cone being raised to form dellecting abutments, the w l ci the cone being perforated in the rear of the del'lecting faces oiC the abutments.

5. Rin exhaust inul'ller having in combination a shell provided with an inlet and outv let, a plurality ot hollow cones arranged having closed spices toward the inlet, said cones being provided with abutnients shaped to deflect the gases outwardly, and having perforations for the flow of gases to the iiiterior of the cones, and an oppositely arranged hollow cone having perforated walls.

6. iin exhaust muffler having in combination a shell provided with -an inlet and outlet, parts or elements adapted to break up the stream ol ini'iowing gases and to deflect the line oi liow, a iframe removably secured within the shell and having said parte or .elements secured thereto.

7. An exhaustniullier having in combina* tion a shell having a removable head, a plurality or hollow' cones having perforated V.walls and provided with deliecting abutinents, a series of bars removably secured within the shell and having the cones secured thereto.

ln testimony whereof, .l have hereunto set my hand.
