MUFFLER CUT-OUT FOR EXPLOSIVE-ENGIN ES.
To all'whom it mag concern:
#Be it known that I, LoUIs RAFrALoviori,
a citizen of the Republic of France, now
have invented certain new and useful Improvernents in Muffler Cut-Outs for Explo-.
.SIVB-EllglIlQS, of which the following is a specification.
My 'nvention relates to devices whereby the operatorof an-ex losive engine provided with an exhaust mu er or other sound-deadening means, may at will provide a discharge'opening for the exhaust ofthe engine without causing the same to pass through the mufller.
- It lS well knownthat exl iaust mufiiers "such as -.are commonly used in connection with explosive engines detract considerably this result.
v The invention consists in the novel constructlon, arrangement and combination of parts as hereinafter more particularly described.
In the accompanying drawings, Figure l is a side view of a portion of the exhaustdischarge pipe of anexplosive engine, show- 111g my invention applied thereto, the latter being shown in'section; Fig. 2 is a top view of the exhaust pipe, showing a portion of its upper wall above the muffler cut-out broken away so as to look down into the interior of the latter; Fig. 3 is a transverse vertical section through the line 3-3 of Fig. 1, Fig. 4: is a-sectional view of the cut-out showing another form of escape valve, and Fig. 5 is a sectional view of a portion of .my invention, showing the preferred form of the same. Fig. 6 represents a side view partly in elevation and partly in section of an automobile provided with this improvement.
A represents a portion of the exhaust pipe of-an ex losive engine, at one end of which of the pipe -A an opening is formed, adapted to permit the exhaust from the engine to In the lower part,
pass into the cut-out as hereinafter described. 5 I i The cut-out is secured to the pipe imme-f' main or lower portion of the cut-out, and underneath these two projecting ends are passed the Ushaped supports D D, the upper ends of which are screw-threaded and pass through perforations in the ends of the supporting-pieces E E and are secured by the nuts-F F.
The lower or main portion of the cut-out comprises. an exhaust chamber C having in one wall avalve openingprovided with a valve-scat in which when normally closed lies a valve G having a stem H to which the valve is secured by a pin I. This stem slides in a sleeve K fixed to and projecting from the other side of said chamber opposite said valve opening, said sleeve being of sufiicicnt length to steady the stem and cause the valve to always find its scat upon closing.- A coiled spring L extends between the pin M in the stem H, and the sleeve K, and serves to keep the valve G normally closed against the pressure of the exhaust, but yields upon being subjected to any unusual or excessive pressure. It will be seen that the device thus also performs the function of a safety valve, yielding in case the pressure of the exhaust becomes too great, and permittlng its escape directly without passing through the mutller/ The exhaust chamber G on the mufller cutout is of somewhat larger area than the exhaust pipe A, and the valve opening in said exhaust chamber is preferably of. the same or approximately the same area as said exhaust pipe, so there will be no back pressure in the exhaust pipe when the valve .of the cut-out is fully open.
In Fig. 4 is shown another form of my lilvention in which the valve G is adapted to be drawn inward to allow the escape of the exhaust when it is desired to allow same to escape without passing through the muffler. In this form a coiled spring L is provided to close the valve again after it has been opened, one end of the spring being hooked specification of Letters Patent. "Patented NOV. 30, 1909.
I Application filed January 18, 1908. Serial No. 411,467.
portion projects longitudinally beyond the into a perforation in a lug N and the other the valve is opened. by the operator, whereupon the exhaust passes 'into the open air directly through the openingthus caused.
Fig. 6 shows the invention applied to an automobile. The engine exhaust pipe A is there shown connected at one end with the explosive engine 10 and at'the other-end with a muffler-'20. The form of cut-out C there shown correspondswith that shown in Fig. 4 in. which the valve opens inward. A cord S is connected at one end to the valve spindle H and passes over a pulley T and through eyes Y in the dashboard where" it may be conveniently reached by the operator. The
use of my invention also serves to keep the mufller from becoming clogged by oil and debris of various kinds carried out by the exhaust, as these will tend to drop into the well formed by the cut-out and will be blown out by the exhaust wheneverthe valve of the cut-out is opened.
It is obvious that various changes in the details of the construction and mode of attachment of my invention may be made Without departing from the .spirit of the invention.
One of the principal advantages of my invention is the .ease with which it may be attached to engines already in use which. are not provided with such a mufi'ler cut-out device. All that-it is necessary to do in such a case is to provide a suitable, opening in the exhaust pipe and my invention clamped thereon in the manner described orin any suitable way.
Having thus described my'invention, what I claim as new and desire to secure by Letters Patent is as follows: f
1. The, combination. of. an explosive engine exhaust pipe provided with a discharge opening on one side, a mufller connected with sa1d pipe, a mufller cut-out dlsposed on sa1d exhaust pipe opposite said discharge open- .ing between the engine and the muflier and comprising an exhaust chamber of lar' er area than said exhaust pipe and provi ed with an exhaust opening of approximately the same area as said exhaust pl rpe, a valve for closing said opening, a spri g for seatlng said valve, and means for opening said va ve against the tension of said spring.
. 2. The combination of an explosive engine exhaust pipe flprovided with a discharge openmg, a mu er on said exhaust pipe, and
