SPECIFICATION forming part of Letters Patent No. 737,443, dated August 25, 1903.

Application filed July 16, 1902. Serial No. 116,767. (No model.)

T0 at whom it may concern.-

Be it known that I, LOUIS P. MOOERS, a citizen of the United States, residing at Oleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Mufflers, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings.

If in operating engines of different types the exhaust is permitted to flow directly into the atmosphere, a considerable puffing noise results. This is very objectionable, especially in connection with explosion-engines which are used on motor-vehicles; and it is the object of this invention to obviate that difficulty by a peculiar form of muffler set forth in the following description and claims and illustrated in the drawings.

Referring to the drawings, Figure 1 is a longitudinal cross-section showing the device, and Fig. 2 is a vertical section on line 2 2 of Fig. 1.

Referring to the parts by letters, A represents a casing closed at one end bya funnelshaped ring B and at the other end by a head 0, in which is secured the exhaust-pipe D, leading from the engine. The outside of this casing is wrapped with asbestos E or other suitable non-heat-conducting material and has a jacket F around the outside of this asbestos.

The inside of the casing A is provided with several chambers a, a, a a and a, which decrease in size from the inlet end of the casing to the outlet. These chambers to a, &c., are formed by transverse partitions G, which have suitable'perforations g therein and cupshaped baffles g These partitions are severally of such a size that they fit tightly within a sleeve-like end portion h of a funnel-shaped ring II. These rings correspond in width to the chamber in which they are placed, so that their small ends, from which the gas is discharged, are in close proximity to the cupshaped baffles g and the force of the discharge from the ring will be taken up within these baffle-cups 9 A funnel-shaped ring H is provided for the head 0 at the inlet end i of the casing.

The operation of the device is as follows:

As the discharge comes from the engine the volume of the gas is concentrated by the rmg ,H and directed into the first baffle-cup on of suflicient size to accommodate the charge that has become cooled. The operation is continued until the gas is finally discharged from the funnel-shaped ring B at the end into the atmosphere, the noise of the exhaust having been spent by the several compressions of the gas and in the circuitous route the gas has taken in its progress.

This device is designed particularly for use on automobiles which are operated by explosive-engines; but it will be readily seen that it can be applied to any sort of engine and perform the same function.

Having described my invention, I claim- 1. In a muffler, the combination with the casing, of partitions separating the easing into chambers decreasing in size from the inlet to the outlet, rings for concentrating the charge within said casing and baffles for operating in connection with said rings for baffling the charge, substantially as described.

2. In a muflier, the combination with the casing, of partitions separating the easing into chambers of different sizes, rings for concentrating the charge within said casing, said rings having openings increasing in size from the inlet to the outlet and baffles operating in connection with said rings for baffling the charge, substantially as described.

3. In a muffler, the combination with the casing, of perforated partitions within said casing separating it into chambers decreasing in size toward the outlet-opening, funnelshaped rings within each of said chambers for concentrating the charge, and baflies operating in connection With said ring, substantially as described.

4. In a muffler, the combination with the casing, of partitions separating the easing into chambers decreasing in size from the inlet to the outlet, a funnel-shaped ring Within each of said chambers for concentrating thecharge, said rings being provided With openings increasing in size from the inlet to the outlet and baffles operating in connection With said rings, substantially as described.

5. In a muflier, the combination With the casing, of perforated partitions within said casing separating it into chambers decreasing in size toward the outletopening, funnelshaped rings Within each of said chambers for concentrating the charge, and cup-shaped baffles operating in connection with said ring, substantially as described.

ing in size from the inlet to the outlet of said casing and a suitable jacket for said casing, substantially as described.

In testimony whereof I hereunto aifix my signature in the presence of two Witnesses.

LOUIS P. MOOERS. Vitnesses:

13. W. BRooKETT, ALBERT ll. BATES.
