MUFFLER.
Application filed April 15, 1918.
To all whom it may concern:
Be it known that we, JOHN J. REDEKER and HERBERT L. THOMPSON, citizens of the United States, residing at Elgin, in the r the parts.
In the accompanying drawing 'Figure 1 is a View mostly in section of a mufller constructed in accordance with the principles of this invention. 7
Figs.'2 and 3 are inside views of the two end pieces;'and
Fig. 4 is a view of a portion of one of the sections of which the mufller is made up.
It is common practice to make mufflers of this kind of sheet metal and'castings, but an outer casing is usually provided'which covers the other parts, except the end pieces, and the present invention therefore is for a different construction in which the sections .which make up the muffler are nested together so that their outer edges form the casing, the sections being held together he- 1 tween the end pieces by a suitable fastening device. The mufiling or silencing effect and the capacity ofthe device can be varied by varying the number of intermediate sect1ons. The mufller being light and simple in construction is particularly designed and intended for use in connection with small gas engines, but of course may be made for engines of larger sizes,
In this muffler there are end pieces 1 and 2 with intermediate sections 3 and arranged alternately between the end pieces. The end piece 1 is formed with an outer hollow tubular extension 5 threaded on the insid'e to receive a correspondingly threaded end of a pipe 6 which leads from the engine to which the mufller is attached. 0n the inside of this endplate are ribs 7 for-support ing a central threaded hub 8 into which one end'of a threaded rod 9 is screwed. The

Patented May 20, 1919.
Serial No. 228,581.
These sections 3 and 4 are similar in the respect that they are' both formed of sheet metal, and the outer edge of each one is bent or crimped in one'direction to form a sort of a flat cup with a portion 14 of reduced diameter adjacent the flat or transverse portion thereof so that the edge of eachsection will engage and fit over the reduced portion 14 of the next one, thereby allowing them to fit tightly over each other forming a subbut spacing the transverse portionsof the sections apart so that they will not fit too tightly within .each other, but will allow a considerable space for the circulation of the gas admitted to the muffler. The sections 3 have a large central perforation 15, and the sections 4 have a smaller perforation 16 through which the rod 9 may be inserted with some play to allow for inaccuracies, the perforation 15 of the sections 3 being sufiiciently large to permit the whole volume of gas admitted through the tubular extension 5 Without any restriction thereof. In the other sec tions 4 a number of tongues 17 are pressed outwardly from the bottom of the section forming perforations 18, and the tongues being only partially bent back in an inclined position, so that the gas in passing through the perforations 18 is given a kind of a whirling movement which further breaks up and diffuses the gas.
In order that the edges of the section adjacent the end piece'l may fit properly over it, the edge is forr'nedwith an inclined portion 19 corresponding to the reduced portion 14 of the sections themselves, and when the sections are pressed together, between the end plates, the one nearest to the end plate 1 is ressed' firmly on the inclined portion 19 so that a substantially tight joint is made thereby. The other end plate 2 abuts the flat side of one of the sections 3, and it is unnecessary for the edge of this end piece to be shaped to receive the edges of the sections.
This end piece is therefore preferably made fiat and. slightly lessin diameter than that of the adjacent section, the rounded portion 10 communicating freely with the interior of the section?) through its central opening 15. p
In assembling the'parts, the sections 3 and 4 are preferably arranged -alternately with oneof the sections 3 at each end and they are. clamped between the end plates 1 and 2, as described. The exhaust'of' the engine enters through the end piece 1 Where it. passes through the center of the sections 3 and is given a whirling movement through the'perforations nearer the periphery of the next section 4:. This action isirepeated until the exhaust escapes from the other end of the mufller through the tubular member 11 of the end piece 2. It is easy to take this mufiler apart for repair or for cleaning it,
center thereof so that the exhaust will be given a tangential whirling movement as it passes to the next section. In testimony whereof we have slgned our names to this specification von this 8th day of April A. D. 1918.
