To all "whom it concern? :Be it known that'l, WALTER T. Rice, a citizen of the United States, and a resident of Chicago, in the'county ofCook and State of; Illinois, have invented certain new and useful Improvements in Combined Mufflers and Exhaust-Pipes for Internal-Combus tion Engines, of which the following is a specification; Y I This invention relates to a device to be attached to internal combustion engines to receive the exhaust gases therefrom and has sen the noise madeby the discharge thereof. The object of the invention is to obtain a combined muffler and exhaust manifold which does not produce any considerable back pressure, as itis termed n the art, that is, a device which does not produce much friction or other resistance to passage of the waste products of combustion theret-hrough; but which will materially lessen the noise madeby' the discharge of said gases from the exhaust ports of the engine.

A; further object of theinvention is to ob tain a device which contains few parts, and which is easily separated int-o the several parts thereof; and also easily attached to and taken from the engine for which it is fitted.

A 'further object is to obtain a device which is not liable to lee-broken when sub jected to severe usage, and not liable to get out of order.

The device ispri-marily designed for attachment to automobile engines or motors.

In thedrawing Figure 1 is a side elevation of the front end of an automobile, the motor thereof being indicated by broken lines as under'the hood, and a device embodying this invention attached thereto. Fig. 2 is a vertical section, on line 2-2 of "Fig. 3, viewed in the direction indicated by the arrows. vAnd Fig. 3 is a vertical sec tion on line 3 3 of Fig. 2,-Viewed in the direction indicated by the arrows.

A reference letter applied to designate a given part is used to indicate said part.

throughout the several figures of the drawing, wherever the same appears.

A is the chassis of an automobile; B is the hood, and C is a front wheel thereof.

The broken lines D indicate a four cylinder internal combustion motor.

E is a device embodying this invention, and consists of the flaring tubes e, e, horizontal cylinder 6" e, and deflector G. Tubes cylinder which is provided with the discharge passage way H, and it will be observed that said end has somewhat the appearance of a funnel, and that said dis,- charge passage way is located at-the larger part of said tunnel shaped end, on. the cone sha" d wall thereof.

' J, are the inlet apertures of'the several flaring tubes 6. The upper ends of the flaring tubes 0 are curved, as at X, Fig; 3, to bring the device, particularlythe horizontal cylinder 6 e", close to the chassis is...

K is a brace securing the horizontal cylinder of the device in place. The flare which is given to the tubes e is to permit the exhaust gases which are delivered thereinto from the exhaust ports of a motor to expand before being dischargedtherefrom The part e. is easily separated rom the.

part a, all that is necessary being to remove the bolts F and then to drop one side of the part edown and disengage the hooked parts ffrom each other.

.The operation of the device, 1s The' waste products of the combustion in the cylinders of the motor are discharged there from through the exhaust ports thereof. into the tubes 6 by way of the inlet apertures and said exhaust products flow through said tubes into the cylinder e c, and from thence, over the deflector G, out'of the cylinder by way of the discharge passage way H.

As said waste products flow over the deflector G they may, and some thereof'do, come in contact with the funnel shaped end or the horizontal cylinder, and the direction given to said products. destroys the pulsat- 'ing character thereof, and bgetlittle noise 1s made as they issue from the passage way H.

Particular attention is called to the fact that when the motor or engine is run with the part a removed from the device a definite direction is given to the exhaust ases I 'i discharged irom the exhaust ports 0 the tensify 11113 sound d whim; of sound is m 'clavico may, lhero mm: 6 removed to ina discharge of wzisto motor and an imrre produoocl there v fore, he used with the guseaa frsom the motor.

I claim- 1. A. two PEN; horizontal cylinder, flaring; tubes arranged to dischnrgo at the larger ends the-mm respectively, into said horizontal c lindor, and adapliedl to receive the d'isl'eharged from lhe exhaust ports of an internal wmbustion motor at the smaller ends ihei'oof, in combination with a dofleotor in said oylinclei' said cylinder 13200- vidwfl with :1 ills-charge passage way adjacent to one end thereof, and said deflector lone-(l between said discharge passage 1 and the disclmrge oncl of the flaring lube nearest thereto 2. ll. two part horizontal cylinder pro- Villfll with a funnel shapfll and and with, a :lisohurge passage way through the side; wall of FiillLl funnel slmped end, in combination with flaring tubes which are curved at the smullor curls i'hei'eoit} respectively, and adapted to rocoi c the gases disclmrged from the exhaust porls of an internal oom- 1,0 sopw bustion engine, and to disoha e said gases from the larger emls of SE tubes mto the said hmuzon'wl cylinder and a ClBfiBCt-OI in said QIlIIMlQDPUEIllODBd laetween thodlsclmrgo passage Way and the larger end of the tube nearest theroto.

A. two part horizontal cylindel provided wlth a funnel shaped encl and with '5 discharge way through the side Wall of sand funnel shaped and, moans to attach the parts of said cylinder together, and one of said parts provlciod W'liil) funnel shaped "tubes iiftegml therewith, with the smaller ends of said tubes curved and adapted to receive the gases discharged from the exhaust ports of an inte'nal combustion motor WALTER T. RICE. In the presence of- '7 CHARLES TURNER BROWN, C. A. ADAMS.
