MUFFLER CONSTRUdTION.
Application filed August 4, 1927. Serial No. 210,694.
This invention relates to mufller constructions and more particularly to the construc- No. 1,615,564, granted January 25, 1927, for
combined. muffler and cut-out.
A further and more specific object of the invention is to provide an improved mufller construction whereby the sound emanating from the 'muflled exhaust is materially reduced. I
A still further object of the invention is to provide a structure including. a plurality of muflling valves, such as shown in the prior patent above identified, wherein one of these valves is so constructed that it serves not only its 'muflling function, but likewise serves to maintain the muflling valves in their muflling position. y
These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a longitudinal sectional view.
Figure 3 is anenlarged detail view sh0w-' ing the different arrangement of the conductingztubes employed in the intermediate shell. eferring 'now more particularly to the drawings, the numeral 10 generally designates an exhaust tube having adjacent its I rear end'a-circumferential series of openings that the rear head has adjacent its periphery,
as indicated at 14, an exhaust opening,
through which the muflled exhaust gases may pass. Adjacent faces of the heads have recesses 15'receiving the ends of a sleeve 16, which is of slightly greater diameter than the exhaust tube, so that a chamber 17 is formed between the exhaust tube and sleeve. A cover or outer shell 18 has its ends suitably secured to the peripheries of the heads .12 and combines with the sleeve 16 to produce an annular chamber 19. The rear head 13 is secured upon the exhaust tube 10 adjacent the "annular series of openings and between this series and the end of the tube, while the head 12 is well spaced therefrom Adjacent the valve.
head 12, the sleeve 16 is provided with openings, the edges of which are defined by tubes 20, which may extend either inwardly or outwardly from the tube, as illustrated in Figures 1 and 3 respectively. It will be obvious that exhaust gases, if obstructed from passage through the rear end of the exhausttube, will pass through the openings 11, entering the annular chamber 17 near the rear end thereof and moving to the forward end thereof where they-pass through the tubes 20 into the forward end of the annular chamber 19. Moving rearwardly through this, chamber, they pass to the atmosphere through the exhaust opening 14. It has been. found that the tubes 20 serve to materially increase the muffling effect which is obtained by the use of a similar structure in which ordinary openings are provided through the shell, since they prevent the Venturi action resulting from the formation of an opening through thin metal.
The exhaust tube 10 has arranged therein arear or control valve 21 and a pair of forward muffling valves 22 and 23, the valve 22 being arranged rearmost. Each of the valves 21, 22 and 23 is of the butterfly type and arranged upon aligned parallel pivots. The valve 22 is perforated for the passage of exhaust gases, so that the space between this valve and the valve 21, when the valves are in the closed position, acts as a central muflier chamber. The valve 23 is fragmentary, being in realit only one-half of a butterflyty e ases moving longitudinally of t e tube 10 from the intake toward the exhaust end thereof will exert pressure to move the valve 23 from the open to the closed position.
:The pivot stems of the valves 21, 22 and 23 have operating arms 24 which are connected for simultaneous movement by a rod 25 which may be in turn connected to an operating element 26. 1
It will be obviousthat when the valves 21, 22 and 2 3 are moved to the open position, the pressure of gases against the fragmentary. valve will constantly urge the same to closed position. Since the pressure upon the valvesj21 and 22 will be balanced at opposite sides of the pivot, it follows that this pressure will act to move all of the valves to closed position, thus eliminating the necessity of a relatively heavy spring for, accomplishing this function. It is pointed out that heavy springs resisting the movement of the valves render operation of the cut-out dif ficult and the device unsuitable for applicav I i tion to cars which are driven by women. It is pointed out that the valve element 23 not only acts to assist in the closing operation, but likewise functions when in closed position as a battle combining with the valve 22 to produce a muffler chamber within the exhaust tube, thus further reducing the noise of the escaping exhaust gases.
Since the construction hereinbefore set forth iscapable of a certain range of change and modification without materially departing from. the spirit of the invention, 1 do not limit myself to such specific structure except as hereinafter claimed.
1 claim t 1. In combination, an exhaust tube, a muffler communicating with the tube intermediate the inlet and outlet ends of the tube,
a valve between the point of communication and the outlet of the exhaust tube and in one position thereof closing the tube, a second valve between the point of communication and the inlet of the exhaust tube and in one position thereof partially closing the tube, an element Within the tube, a connection between said valves and element whereby upon movement of the element in one direction' the valve will move to closed position, said element being constantly urged by the passage of exhaust gases through said tub in said direction.
2. In combination, an exhaust tube, a muffler commumcatlng with the tube lnter-j mediate the inlet and outlet ends of the tube, a valve between the point of communication and the outlet of the exhaust tube and in one position thereof closing the tube, a second valve between the point of communication and the inlet of the exhaust tube and in one position thereof partially closing the tube, an element within the tube, a connection between said valves and element whereby upon movement of the element in one direction the valve will move to closed position, said element be ing constantly urged by the passage of exhaust gases through said tube in said direction, said element combining with the last named valve to produce a mufiler chamber.
