J. DICKMAN EXHAUST SILENCER Filed July 31, 1922 Patented June l0, i924.
J AMES DICKMAN, OF NEW ORLEANS, LOUISIANA, ASSIGNOR OFiON'E-HALF TO CAESAR MAESTRI, 0F NEW' ORLEANS, LOUISIANA.
EXHAUST Application ledgvnly 31,
To all whom t may concern Be it known that I, JAMES DroKMAN, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Exhaust Silencers, of
which the following is a specification.
My present invention pertains to internal combustion engines and it contemplates the provision of a device that may be readily and quickly secured on the exhaust pipe of the engine so to eliminate the metallic sound or noise of the exhaust.
The invention further contemplates the provision of a device adapted to. be secured on the exhaust pipe in such a manner that the gases from the engine are permitted to expand thereby eliminating the annoying sound present in exhaust pipes now in use.Y
Other objects of the invention will be fully understood from the following description and claim when the saine are read in connection with the drawings accompanying and forming part of this specification, in which Figure l is a side elevation of my device.
Figure 2 is a sectional view taken on the line designated by 2--2 in Figure l.
Figure 3 is a similar view taken in the plane indicated by the line 3-3 of Figure l.
Figure 4 is a sectional view taken in the plane indicated by the line 4-4 in Figure l.
Similar numerals of reference designate corresponding parts in all the views of the drawings. y
My novel device comprises the cylindrical portion l that is adapted to be secured at its extreme end to the top of the exhaust pipe of an internal combustioneengine, and this cylindrical portion l merges into a chamber of ball shape which comprises the lower end 5, the central body 3 and the upper or outer end 7 and these members comprising the ball portion are integral with each other as well as the cylindrical portion l and are each provided with a series of outlets 4, 6 and 8 respectively. Secured to the upper or outer portion 7 is a cylindrical portion 9 that 1s similar to the portion I witlr the exception that it is slightly decreased in circumference with respect to the portion I and this cylindrical portion 9 is also provided with a series of apertures 10 and is formed integral on the SILENCEVR.
1922. Serial No. 578,583.
upper portion 7 of the ball chamber. As will be noted by reference to Figure 2 I provide the central portion 3 of the ball at its upper and lower ends with the wire netting 12 and this netting when desired may be formed of rods or the like in the discretion of the manufacturer.
In order to retain the device on the end of an exhaust pipe I provide a collar that is adapted to surround the decreased cylindrical portion 9 and secured to this collar are cables 1I that may be attached at any point desired to the under side of a motor vehicle or wherever practicable.
In the practical use of the device the exhaust of the engine will pass from the exhaust pipe into my novel device and because of its peculiar configuration as well as the apertures that are provided in the various elements of the silencer, the sound at the outlet will be mufiled.
My invention is extremely simple in construction and is readily adapted for use in connection with various sizes or styles of exhaust pipes and mayl be made of any material compatible with its purpose.
Having described my invention what I claim and desire by Letters Patent is In a device for the purpose set forth, the combination with the exhaust pipe of an internal combustion engine of a comparatively large circular conduit having apertures therein, a large globular portion with apertures therein and formed integral with one end of the large conduit, a foraminous screen secured interiorly of the globular portion and at the center thereof, a comparatively small conduit having apertures and formed integral with the globular portion directly opposite and on the same axis as the large conduit and a collar secured around the small conduit at the longitudinal center thereof and rods extending from the second collar for securing and bracing the entire device with respect to the under side of a motor vehicle.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
JAMES DICKMAN.
