PATRICK J. COLLINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO AMERICAN SILENCER COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF DELAWARE.
MUFFLER.
Specification of Letters Patent.
Patented July 15, 1913.
Application filed April 16, 1913. Serial No. 761,522.
To all whom z'tmay concern Be it known that I, PATRICK J. COLLINS,
citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Mufilers, of which the following is a specification.
This invention relates to a mufiier for silencing the exhaustfrom internal combustion engines and the purpose of-the invention is to provide a device of this kind which will be inexpensive to construct and assem ble and which will'be effective in operation.
In the accompanying drawing, which illustrates my invention, Figure 1 is a central longitudinal section through the mufiler; and Figs. 2, 3, 4, and 5 are transverse sections through the same on the lines 22, 33, H, and 5-5, respectively of Fig. 1.
Referring to the drawing, A indicates the mufiler as a whole, comprising a preferably cylindrical inclosing casing 1, having heads 2 and 2"* at its ends, provided with inlet and outlet ports 3 and 8*, respectively, the former port adapted to be connected to the exhaust pipe of an internal combustion engine. These heads have spiders I on their inner sides and they are connected together and clamped against the ends of the casing by a bolt 5 which extends centrally through the casing and through the hubs 4 of the spiders.
Spaced apart from one another, at'suitable intervals throughout the length of the casing, and secured to its inner wall, are bafliing partitions 6, 7 8, and 9. Four partitions are shown in the drawing, but the number may be varied, according to the size of the mufller. These partitions have openings or ports therethrough, indicated at 6 7 8*, and 9 respectively, each opening being eccentric to the longitudinal axis of the casing and preferably of circular form. The successive openings are angularly displaced with respect to one another about the axis of the casing, and preferably this angular displacement is progressive from one end of the series to the other, so that the arrange ment of the entire series of openings is spiral. Thus, in the muffler shown in the drawing, having four partitions, it will be seen that the successive openings 6, 7 8 and 9 are arranged progressively 90 degrees apart, so that the gases traveling through the mufllcr must necessarily partake of a whirling motion.
The bolt 5 forms a central support for a series of battling members 10, ll, 12, and 13, in the form of disks of smaller diameter than the openings or ports in the partitions. These disks, it will be seen, are alternately arranged with respect to the partitions, and they are in line with the openings in said partitions, so that the gases, passing through the muffler cannotflow directly from port to port in the partitions, but will be deflected by the central battling members, which are in line with said ports, and caused to partake o f thewhirling motion due to the spiral arrangement of the ports or openings in the partitions. The disks 10-13 are preferably of such diameter that, when they are secured to the central supporting rod, the
'latter, with the disks attached, can be passed through the openings in the partitions, which accordingly facilitates the work of assembling.
In assembling the mutiler, the partitions are secured within the casing and the disks are secured tothe rod 5. One end of this rod is then connected to the head 2, and the rod with the disks uponit is passed through the openings in the partitions, the head 2 then fitting against the casing. The 0pposing head 2 is then placed on the opposite end of the rod and secured thereto in any suitable way, and the two heads are thus clamped tightly against the ends of the casing and the mutller is then ready for use.
What I claim is:
1. A mutller comprising an inclosing casing a series of spaced bafiiing partitions in said casing, each partition having an eccentric opening therethrough, and a series of bafiiing members of smaller diameter than said openings alternately arranged with re spect to said partitions and in line with said openings.
2. A muffler comprising an inclosing casing a series of spaced battling partitions in said casing, each partition having an eccentric opening therethrough and the open ings in the successive partitions being angularly displaced with respect to one another about the axis of the casing, and a series of battling members of smaller diameter than said openings alternately arranged with re spect to said partitions and in line with said openings centric opening therethrough, a support extending through said openings, and a series of bathing members of smaller diameter than said openings secured to said support and alternately arranged with respect to said partitions.
4. A mufller comprising an inclosing casing a series of spaced battling partitions in said casing, each partition having an eccentric opening therethrough and the openings in the successive partitions being angularly displaced with respect to one another about the axis of the casing, a support extending through said openings, and a series of bafiiing members of smaller diameter than said openings secured to said support and alternately arranged with respect to said partitions.
5. A mufller comprising an inclosing BEST AVAILABLE COP;
casing a seriesof spaced battling partitions in said casing, each partition having an eccentric opening therethrough and the openthrough said openings, and batliing disks or members secured to said support between the partitions.
6, A. muitier comprising an inclosing casing a series of spaced battling partitions in said casing, each partition having an eccentric opening therethrough, and a series of bathing members of smaller diameter than said partitions alternately arranged with respect: to said partitions and in line with said openings.
In testimony whereof I have aflixed my signature in presence of two witnesses.
