Specification of Letters letent.
Patented Maj; 3 191() l Application filed June 3.6, 19GB. Serial No. 502,409,
To all whom it may concern:
Be it known that I, VVILLIn Owen Tn; a subject of the King of Great Britaiin and residing at the city of Janesville, county ot Rock, and State oI 'Wisconsiin have invented f certain new .and useful Improvements in gated chambers serially connected together by constricted passages; to provide a construction'in which the muffler may consist of a single pipe orconduit provided with said chambers and con-stricted passages and which dispenses with .the usual large and more or less clumsy mulller chamber; to pro- `videa 'construction which is of relatively light weight, simple and economical in inanufacture and at'tlie saine time performs its function in a reliable and eilicient manner; and in general to provide improved constructions of the character referred to.
up considerable amount of space.
The invention consists in the matters hereinafter described and more particularly pointed out in the appended claims'.
In the drawings Figure l is a fragmentary longitudinal sectional view ci' a preferred embodiment of my invention. Fig. 2 is a transverse sectional view taken on line 9 Q of Fig. l and looking in the direction' ol arrows. Fig. 3 is a vieivsiniilar 'to Fig. 'l but showing a somewhat modified construction. Fig. 4 is a transverse sectional vieuY taken on lines L? ZLof Fig.- 3 and looking in the direction of the arrows.
In automobiles and similar vehicles the explosive noise of the iras from the exhaust side of the engine is suc as to necessitate the use of inulilers. In the constructions now in use the exhaust is discharged into a relatively large separate niuliler chamber before it passes into the atmosphere, This mntller chamber which is secured to the chassis oi' the vehicle is more or less clumsy and taires liloreover it has heen found that in order to render it at all times elicient it has been necessary to provide it With lining and valve mechanisms. In the present invention the usual muliler chamber is dispensed with and the exhaust gas discharged through a single pipe connected 'to the exhaust.
Referring to the drawings 'lo designates as a wh muilier pipe coniprising'a series of relatively narrow elongated chambers i2 communicating with each other through constricted .passages 3. These passages are 'formed by merely flattening the sides of the pipe together in the .manner shown more clearly in Fig. 2. The act oi' forming thespassagesj of course,' divides the pipe into a plurality of chambers Q in :in obvious man ner. The exhaust. gas after it passes through the pipe is preferably discharged through a relatively narrow opening` 4. formed by llattening the end of the pipe in. a enerally similar manner. The pipe may, i? desired, oi' course, consist of aplurality of 'similar sections united in any suitable manner.
In Figs. 3 and l I have shoivn a somewhat modified construction in which the .constricteqi passages 3 are alternatelydisposed at richt angles to each other in place of be ing Formed in substantially the same plane as in Fig. l. The inlet end of the muliler may be provided with a collar 5 whereby it can be more readily Connectedto the main exhaust pipe of the engine.'
The operation .of the device is apparent. Bis the exhaust gus passes through the series of substantially separated chambers, its ex-` plosive or-gce is gradually broken up und the gas finally u scharges noiselessly into the atmosphere iii a relatively steady stream. By increasing the number of chambers an explosive fcrce of any velocity can be sore- `duced as to he entirely ohviated. It is to heunuersiiood that the invention 1s not limited to the detail ot construction shown except as set forth in the claims.
I claim as my invention:
l. In a inuiller, the combination vvith a i conduit arovided with a plurality of elongated substantially closed chambers serially connected together by constricted passages formed by flattening the sides of the conduit.
2. A muffler comprising a pipe having :i plurality oi elongated chambers serially communicating with each other throng
