" ing to be a full', clear. and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the saine.
This invention relates to -inuftlers and has for an objectto provide a mufller froin which the gases are sucked out during the exhaust stroke of the engine and in which a vacuum is created in the muiller during the compression stroke so that back pressure will be positively eliniinated i t Yith the above objects in view. the invention consists of certain novel details of construction and combination of parts hereinafter full)7 described and claimed, it being understood that various modifications .may be made. in theV minor details of construction wit-hin the scope of the appended claim.
In the accompanying drawings forming part 'of thisV specification: Figui-e1 is a diagraniinatic view showing the application of my invention. Fig. 2 is a longitudinal sectional view through the muffler. Fig. 3 1s a fragmentary sectional view showing the release valve of the in'utller in open position.'
Referrin'l' now to the drawinus in which like characters vof reference designate similar part-s, 10 designates an internal combustion engine, 11' designates the m'ulller, and 12 the exhaust fan, .the latter being continuously actuated from the crank shaft. of the engine by ineans of a chain drive 13. The exhaust manifold 14 'of the engine is con-4 nected by a pipe 11" to the inuilier, and a pipe 16 connects the muffler with the exhaust` fan. .The burnt gases are exhausted from the muliier continuously by the exhaust fan sothat on the exhaust stroke of the engine the ninfller will be quicklypurged of bin-nt gases While` on the.compiession stroke ol the engine a partial vacuum will be created in the niuliler to hasten the purging of the iniililer on the. next succeeding exhaust stroke and thus positively obviate back pressure.
In the present embodiment of my invention I employ in the construction of the Aniuiiler 10, a cylindrical casing 17 which is openings of the baflles.
vspecifieanon ,of Letters Patent. 1 Patented Sept. 1, 1914-.- Appncation aid'necembe; 19, isla' serial No. 737.747. i'
ranged a plurality of concave diskbafileSl.
20, these battles being each formed with a central opening 21, and the openings of'all the battles being in registration. Thej ex-` hans-l lpipe 15- fioin the engine entcrswthedisk head 19 and registers with the central 16 of the fan 'is provided terminally with a U-shaped terminal 22 which embraces the casingr long fitndinally, the -branchcs 23 of the pipe being each provided with a series of intake nozzles 9.4 which project. into the casing between and alternate with the battles. The exhaust from the engine upon enteringthe casing: expands into the various coinpartments formed b v the bali'le and is Jfrom thence drawn off through the nozzles 9.4 by the suction of the fan.
Formedin the head 15 of thi` mulllcr casing is a port 25 which 'is normally closed The suction pipe by anoutwardly opening valve 20, the stein 27 ot' which is equipped with a helical spring .28 that hears against the inner wall ol the casing and' ser\'es to hold the valve closed @Inder ordinary exhaust pressure. lipon an explosioii laking.r place in thc n'mtller the valve will'be forced. opcu against the tension of its spring by thc abnormal pressure of the explosion and will permit ol the abnormal pressure releasing` through the port 25.
The fan 1Q coniprises a cylindrical casing 29 thc ends ot' which are closed by disk heads 30 and 3l. and withinv the casing a shaft 32 is axiallyr disposed and is equipped with fan -blades 33. (hic end oi' thc sha'l't projects freni the casing; and is equipped with a sprocket gear 3i which is rotated from the crank shaft by the aho\e described chain drive 13. Ball bearing boxes 235 and 3G are attached to the headsA 3() and4 3l and journal the shaft. 'lhe suction pipe 1G is formed with a U-shaped terminal Iii' which is connected to the head 30. .in outlet pipe. 3S is provided with a branched terminal 39 which is connected to the head 3l. The burnt gases drawninto the` fan casing by the suction of the fan are discharged from the casing through the outlet pipe 3S.
