Description
Sept. 24, 1929. w. SIDERS MUFFLER FOR AUTOMOBILE ENGINES Filed Nov. 5. 1925 Patented Sept. 24, 1929 PATENT series WESLEY SIDERS, OF FREMONT, NEBRASKA.
MUFFLER FOR AUTOMOBILE ENGINES Application filed November The present invention relates to mufflers, primarily intended for use in connection with internal combustion engines forming the motive power for automotive vehicles.
The primary object of the invention is to provide an improved mut'rler for internal combustion engines of automotive vehicles, which will not only act for silencing the explosive charges from the engine, but will also prevent to a high degree of certainty, the
accumulation of unlired charges from the engine within the muffler; such accumulation of unfired charges being due to various well known reasons, and when ignited by an exploding charge from the engine quite frequently results in serious injury to the muflier and sometimes to the engine.
A further object of the invention is to provide an improved muffler embodying features whereby large incandescent pieces of carbon blown from the cylinders of the engine into the mufller, will be effectively broken into minute particles for quickly extinguishing of the carbon and permitting ready passage of the burning carbon from the mutller, and
thus eliminate possibility of a large incandescent piece of carbon being allowed to remain in the mutlier for possible igniting of a subsequent unfired charge entering the mufiler from the engine.
A still further object of the invention is to provide an improved mutller of this character which is extremely simple in construction, and which mufflers may be easily applied to the exhaust pipes of existing types of vehicles.
Other objects and advantages of the invention will be apparent during the course of the following detailed description, taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing Figure 1 is a central longitudinal sectional view through a muffler constructed in accordance with my invention;
Figure 2 is a rear end elevation of the same; and,
Figure 3 is a view illustrating the mutller as applied to the exhaust pipe of an inter- 5, 1925. Serial NO, 67,135.
nal combustion engine forming the motive power for an automotive vehicle.
Referring to the drawing in detail, and wherein similar reference characters designate corresponding parts throughout the several views; the letter A designates generally an automotive vehicle of u ual construction, propelled by the usual internal combustion engine 15. Extending rearwardly from the engine 13 an d in a direction parallel with the path of travel of the vehicle, is an exhaust pipe C to the rear end of which is attached the improved muffler D into which the exhaust charges of the engine B are directed as through the exhaust pipe C.
The improved muffler is formed with an internally threaded nipple or sleeve portion 5 which is intended for threaded connectiim in axial alignment to the rear end of the exhaust pipe C. Formed at the normally rear end of this sleeve 5, and axially of the sleeve, is a rearwardly flaring hemispherical shell portion 6 forming an expansion chamber 7 into which the exhaust charges from the engine B are directed. Closing the rear larger end of the hemispherical shell portion U, is a concave-convex ballle plate 8 having its convex surface extending into the chamber 7. If desired, this battle plate 8 may be formed. integral with the shell 6 but in the example shown is attached by means of an annular flange 9 which may be curled about an annular rib 10 formed at the rear end of the shell.
The bafile plate 8 is provided with a plurality 0f perforations 11 which may be struck in the plate in a direction from its concave side to the convex side thereof, thus forming a number of sharp inwardly projecting barbs or spikes 12 at the convex side of the plate, and extending in a direction substantially parallel to the axis of the sleeve 5 While these barbs 12 have been shown as being formed by punching of the perl'jorations ll, they may be in the form of spike like members attached to the battle plate, or formed in any other suitable manner ior accomplislr ing the object in view.
It ill readily be apparent that these inwardly extending spikes 12 will. effectively break up any large portions of incandescent carbon which are forced against the baille plate 8 by the exhaust charge from the engine, and render the carbon susceptible of being forced through the perforations 11 and not remain in the chamber 7 in an incandescent or extremely hot condition for possible ignition of a subsequent unfired exhaust charge from the engine.
Such special configuration of the hemispherical shell portion 6, and the concavoconvex battle plate 8, is for the specific purpose of creating a vacuum at the rear of the mufiler when the vehicle is moving forwardly and traveling only by its own momentum, or as when the vehicle is coasting on a down grade. It is well known that upon coasting or drifting with the spark control mechanism in an off and retarded condition, that quite an accmnulation 0t unfired charges form in the mulller and which explode within the mufl'ler from the heat of the exhaust charges from the engine when the spark is moved to an on position. With the special construction 01 the improved mufller as shown, the vacuum created at the rear ot the muil'ler will effectively act for drawing this accumulation of unlired charges from the mull'ler and thus eliminate possible injury to the muflier or engine upon switching on of the ignition system.
From the foregoing description of this invention it will be apparent that an extremely simple and efiicient muffler has been provided which will not only act for silencing of the exhaust from the engine, but also embodies features for preventing back firing in the mui'l'ler of an internal combustion engine of an automotive vehicle.
Various changes may be made to the specific form of invention herein shown and described, without departing from the spirit of the invention or the scope of the claims.
I claim:
1. A mui'ller for internal combustion engines, comprising a tubular internally threaded sleeve portion for attachment to the exhaust pipe of the engine, a flaring shell portion of hemispherical formation, formed at the rear end of the sleeve portion concentric with the sleeve, and a perforated battle plate of concavo-convex formation, closing the rear larger end of the shell with its convex side extending into the shell and spaced a substantial distance from the rear end of the sleeve for providing a relatively large unobstructed expansion chamber and having its outer concave face opening to the atmosphere.
2. A mufller for internal combustion engines, comprising a threaded sleeve portion for attachment to the exhaust pipe of the engine, a flaring shell portion formed at the rear end of the sleeve portion and forming an enlarged unobstructed expansion'cham- VESLEY SIDERS.
