MUFFLER FOR AUTOMOBILES Filed Jan. 20, 1932 INVENTOR Patented Jan. 29, 1935 UNITED STATES PATENT OFFICE Manuf acturing Company, Pittsburgh, Pa., a
corporation of Pennsylvania Application January 20, 1932, Serial No. 587,660
2Claims.
This invention relates to improvements in mufller structures for muffling the exhaust of automobile engines or the like, and more particularly to an improved construction for fastening the end caps to the muffler body or housing to render said end caps interchangeable with mufflers of different sizes thereby reducing the stock necessary to carry on hand for servicing cars requiring repairs or replacements.
It is among the objects of the invention to provide an improved form of muffler structure in which the end caps are interchangeably mounted by means of clamping bolts and which shall provide for securing anchorage abutments for the bolts to the body of the mufller in such manner as to assure proper alinement of the bolts to render the parts interchangeable and to prevent displacement of the anchorage abutments by the shearing stress placed upon them when the end caps are clamped down.
Another object of the invention is the provision of novel means for providing a sealed or air-tight joint between the muflier body and the end caps without the necessity of welding or otherwise closing the seam.
These and other objects of the invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:
Figure 1 is a sectional elevational view of a muffler embodying the principles of this invention;
Figure 2 a cross sectional view of one end of the muflier;
Figure 3 a plan view of one of the anchorage abutments by means of which the bolts are secured in the mumer housing;
Figure 4 a side elevational view thereof illustrating the manner of fastening the bolts therein;
Figure 5 a top plan view of the anchorage abutments; and,
Figure 6 a detail view in cross-section illustrating the manner of securing the anchorage abutments to the inner wall of the muffler housing.
With reference to the several figures of the drawing, the structure therein illustrated comprises a cylindrical housing 1, end caps 2, and interior baffle members 3, the latter being of any suitable construction and constituting no part of this invention.
The invention resides in the manner of securing the end caps 2 to the muifier housing 1 to render them interchangeable and to this end, the housing is provided with a pair of clamping bolts 4 at each end which bolts project through perforations provided in the end caps.
The ends of the muilller housing 1 are provided with a bead 5 which is produced by rolling in a well known manner, and the end caps 5 2 are adapted to be drawn tightly over the bead 5 to produce a sealed joint. To properly seat the end caps 2 on the radial bead 5, considerable strain must be placed on the clamping bolts 4, and for this reason they are required to be securely anchored to the muffler housing to prevent shearing.
To this end, suitable anchorage members 6 are provided to form anchorage abutments for the bolts 4 and these members are of the form shown in Figures 3 and 4 of the drawing, they being provided with embossed portions '7 of which there are two or more that cooperate with perforations 8 provided in the housing of the muflier to properly locate the anchorage members and to facilitate their assemblage in production. By means of the raised members '7 registering with the perforations 8 of the housing, they will be uniformly and properly spaced in the mufflers so that the bolts 4, after they are fastened therein, will be in proper alinement to receive the perforations of the end caps to render the latter interchangeable in use.
The anchorage abutments for the bolts 4 after they are assembled in the perforations 8 are spot welded as shown at 9, Figure 1, and the bolts 4 are first secured in the rectangular perforations 10 of the anchorages by staking them with a die as shown at 11 in Figure 6 of the drawing. The bolts 4 are carriage bolts having a square shank below the round head and the square shank cooperates with the rectangular opening 10 of the anchorage members to prevent turning of the bolts therein. By staking them in the manner shown at 11 in Figures 4 and 6 of the drawing, the bolts are securely held in place and in alinement on each end of the mufiler to receive the end caps 2 which are placed with their perforations disposed over the bolts and are drawn tight against the annular bead 5 by means of the usual screw nuts 12.
By the above described structure, it is apparent that end caps 2 with different sizes of adaptors 13 can be placed on the muffler body 1 to fit the mufiler to a particular size of exhaust conduit thereby eliminating the necessity for carrying a stock of mufliers of the various sizes which are in demand.
By utilizing the annular bead 5 the end caps 2 are interchangeable in the manner described 65 modifications may be made in the details of con-- struction without departing from herein set forth.
I claim as my invention:
the principles 1. 'A mufiler structure comprising a cylindrical housing having annular beads projecting radially outward adjacent the respective ends thereof, perforated end caps adapted to-overl'ap the ends of the mufiler housing and to abut againstthe aforesaid bead, perforated angle brackets secured on the: interior wall surface and adjacent the beaded ends of said housing, and bolts extending through the perforations of said end caps and brackets to draw and hold the end caps in intimate contact with the beads of the housing,
2. A mufiier structure comprising a housing having annular beads formed adjacent the end thereof, perforated end caps adapted to overlap the ends of said housing for abutting the said annular beads, anchorage abutment's in said housing adjacent the annular beads, bolts for cooperatively engaging said end caps and anchorage abutments, said anchorage members comprisingangle brackets having projections adapted to project through said housing, and said housing having perforations for receiving said projections whereby the said clamping brackets are spaced in proper relation to bring the clamping means in cooperative alinement with the end cap members.
