A TTOR/I/E V UNITED STATES PATENT OFFICE.
WILLIAM F. A. BUEHNER, OF NEWARK, NEW JERSEY, ASSIGNOR TO L. WEISKOPF, OF
NEW YORK, N. Y.
, MUFFLER.
Specification of Letters Patent.
Patented Oct. 1, 1918.
Applicatioii filed November 24, 1915. Serial No; 88,206.
To all whom it may concern:-
Be it known that I, WILLIAM. F. A. Bonn- NER, residing at Newark, in the county of Essex and State of New Jersey, have'invented certain new and useful Improvements in Mufilers, of which the following is a specificatlon.
This invention relates to a mufiler for deadening the sound of an internal combustion engine or the like.
The object of the invention is to provide a simple, cheap, eflicient and easily cleanable m er.
Other objects and aims of the invention, more or less specific than those referred to above, will 'be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.
In t e accompanying drawings which are to be taken as a part of this specification, and in which I have shown a merely preferred form of embodiment of-the invention:
Fi re 1 is a transverse sectional view of a mu er constructed in accordance with the provisions, of this invention.
Fig. 2 is an end elevational view of the structure shown in Fig. 1; and
Fig. 3 is a top plan view'of the mufiler, showing the same in position upon a multicylinder engine, said view being. upon a reduced scale.
Although this invention is shown in the drawin s as being adapted for useupon a two-cylinder engine, it will be obvious that it may be used in connection with a single cylinder or in connection with engines havingfylinders in multiples of two.
eferring to the structure illustrated in the drawing, the reference character L indicates a two-cylinder engine. The cylinders, as 1 and 2, of this engine are shownin opposing position, but it will be obvious that this disposition of the cylinder has no bearing upon the points of the invention.
A casing G is arranged adjacent the cylin.
'der having an opening 3 communicating with the exhaust port of the cylinder 1. The
' casing is formed to provide a passage-way 4, .a passage-way 5 at an angle to the passageway 4, a passage-way 6 lapping back upon the passage-way 5 and openin outwardly into an extension member H. e extension H is provided with a partition 7 therein defining a passage-way 8 communicating with the passage-way 6 and a passage-way 9 lapping upon the passage-way 8. One wall of the extension H defining the passage-way 9 is perforated, as at 10, for the escape of the spent gases. i 7
As the drawing indicates the invention is adapted for use upon a two-cylinderengine, the casing G is made double and an extra extension is provided, as illustrated, to care for the gases from the cylinder 2. An opening 3 is thus provided into the cylinder 2, and passage- ways 4, 5, 6, 8 and 9 are all duplicated for the escape of the gases from the cylinder 2. i
In order to simplify and cheapen the construction the casing is made with a single division wall 11 between its two sets of passage-ways. The exhaustin gases from the two cylinders strike this division wall alternately from opposite sides and continue therealong to their respective points of release. V
' The casing G is preferably made as a single integral casting having flanges 12 thereon by means of which it may be attached to the engine cylinders; The passage-ways 5 and 6 are defined by partition walls or baffle plates 13 provided therein as shown.
The extensions H preferably each comprise a short section of metallic tubing cut to a proper lengthand having their inner ends abutting relative opposite surface p'or tions of the casing G. Portions "of the walls of the casing are removed, as at 14, to provide unobstructed passage outwardly from the passage-ways 6 into the extensions. The walls of the casing are projected outwardly into the extensions H so as to provide the partition 7.. The outer end of the extenslons are closed by cap pieces 15. A bolt 16 extends between the cap pieces 15, through suitable apertures form in the casing, and serves to clamp the extensions firmly and ri 'dly in position upon the casing.
y the above means a separate and dis tinct exhaust passage is provided for the exhausting products of combustlon from each cylinder of the engine and a common wall is provided constituting a bufier against the opposite surfaces of which the exhaust strike. Ample, and sufiiciently tortuous,
. scription or shown in the accompanying drawing shall be interpreted as illustrative only and not in a limiting sense.
Having thus described my invention what I claim as new and desire to secure by Let-.
ters Patent is:
1. A mufiier comprising a casing defining a passage-way and having an opening through the wall thereof at the end of the passage-way, a separately formed hollow extension communicating with said opening for providing a continuation of said passage-way, the outer end of said separately formed hollow extension being closed, and a partition in said extension extending longitudinally thereof from the wall of the casing to adjacent the outer end of the extension and at one side of the opening between said casing and said extension for defining a passage-way from the opening in the casing along one side of the partition to the outer end of the extension and backwardly along. the opposite side of the partition, and said extension having openings leading to the atmosphere.
2. A muffler comprising a casing defining a passage-way and having an opening through the wall thereof at the end of the passage-way, a separately formed hollow extension communicating with said opening for providing a continuation of said passage-way, the outer end of said separately formed hollow extension being closed, and a partition in said extension extending longitudinally thereof from the wall of the easing to adjacent the outer end of the extension and. at one side of the opening between said casing and said extension for defining a passage-way from the opening in the casing along one side of the partition to the outer end of the extension and backwardly along the opposite side of the partition, and that wall of the extension facing said opposite side of the partition being perforated.
through the wall thereof at the end of the,
passage-way, a separately formed hollow extension communicating with said opening for providing a continuation of said passage-way, the outer end of said separately formed hollow extension being closed, and a projection formed upon the wall of the casing at one side of the opening therethrough projecting into said extension so as to define a partition in the extension terminating short of the outer end of said extension, and said extension having openings leading to the atmosphere.
4. A mufiler comprising a casing having a pair of. intake openings thereinto for the entrance of products of combustion, said casing having a pair of other openings through the wall thereof for the escape of said prod nets of combustion, and means dividing the casing so as to form independent passageways between said inlet and escape opening respectively, said means comprising a partition wallarranged in said casing so as to constitute a buffer common to the products of combustion passing through both said passage-ways.
5. A mufiler comprising a casing defining a passage-way and having an opening through the wall thereof at the end of the passage-way, a separately formed hollow cylindrical extension communicating with the opening for providing a continuation of said passage-way, a closure member closing the outer end of the extension, a member formed integrally with the casing projecting longitudinally into said extension to form a longitudinal artition within the extension at one side 0 said opening terminating short of the closure member, one wall of the extension being perforated, and a clamp bolt extending from the casing through the extension and into engagement with the closure member to retain all said parts in operative engagement.
In testimony whereof I afiix my signature in the presence of two witnesses. WILLIAM F. A. BUEHNER.
