MUST-GAS MUFFLER FOR INTERNAL-COMBUSTION ENGINES.
Application filed September 14, 1826, Serial No. 185,892, and in Australia March 18, 1826.
This invention relates to mufllers usable with internal combustion engines for silencing exhaust gases therefrom. The (principal object of the invention is to provi e means I whereby the emitted exhaust gases from the engine are caused to expand and to be readily passed from the mufller without any appreciable noise. 1
Referring to the accompanying drawings in which embodiments of the invention are i1- lustrated, Fig. 1 is a perspective view of one part of one construction of the mufller; Fig. 2 broken longitudinal section corresponding with the mufller part shown in Fig. 1; Fig. 3
front elevation. of the mufller part shown in Fig. 1; Fig. 4 sectional view on line 44, Fig. 3; Fig. 5 sectional detail view illustrating part of muflier at the exit end thereof; Fig. 6 front elevation ofspiral arrangement of mufil'er plates; Figs. 7, 8 and 9 sectional views of modified forms of mufller plates and Figs. 10. 11, and 12 longitudinal sectional views of certain forms of the muflier'complete.
7" With reference to Figs. 1, 2, 3 and 10, an inlet pipe 1 adapted to be attached to and placed in communication with the exhaust pipe from an internal combustion engine has suitably attached thereto a conical chamber 2 within which are secured a plurality of open ended truncated cone plates 3; these plates are of diflerentlengths and diameter and are arranged in the chamber 2 in such relation that open passages 4 will be provided between the said plates and also between the outer one of said plates 3 and the interior of the wall of the chamber 2. As the coned plates 3 are of diiferent lengths aclear central passage 5 is provided facing. the inlet pipe 1 when the plates are assembled so that the plates 3 commencing from the smallest will be placed forwardly of the next smaller one as shown in Fig. 2. Centrally of the plates 3 is the cone plate 6. The forward ends 7 of the plates 3 may be slightly bent to serve in directing the exhaust gases into the passages 4 from the central passage 5.
Rearwardly of the coned gas disperser chamber 2 is an expansion chamber 8. Such chamber 8 is suitably attached to the chamber 2 at one end and at the other end it is also suitably attached to the conical chamber 9 which carries a gas spreader cone plate 10, the latter being secured to the interior of the chamber 9 by lugs 11 or otherwise. The dimeter of the plate 10 is less than the diameter of the part of the chamber 9 to which 1t 1s affixed and consequently a passage for gas 1s provided between the spreader cone 10 and the interior of the chamber 9. An outlet pipe 12 for exhaust gases is connected in any preferred manner .to therear end of the chamber 9. The plates 3 may be secured to each other and to the chamber 2 by the bars 36 such bars being welded or otherwise suitably attached to the plates 3 and to the chamber 2. i
In Fig. 5 an arrangement of the coned plates 3 is shown for use in relation to a coned chamber 13 adapted to be attached to the outlet pipe 12. When such arrangement is adopted a double coned spreader device 14 may be provided in association with the plates 3 and such arrangement is substituted for the chamber 9 and spreader cone 10 there- 1n, the exhaust gases after passing through the expansion chamber 8 gaining access to the open passages 4 and from thence passing to the outlet pipe 12.
Instead of securing the plates 3 by means of the bars 36 (Fig. 1) they may be connected to each other and to the conical chambers in which they are carried by means of the sinuouslv bent wires 15 (Figs. 3 and 4) The plates 3 are shown assembled in concentric relation to each other in Figs. 1 to 5. in Fig. 7, and in Figs. 10 to 12, but if desired the Inufiler plates 3 may be arranged in spiral form as shown in Fig. 6.
A modification of the complete mufller means as shown in Fig. 10 is shown in Fig. 11, in which latter figure the inlet pipe 1 has attached thereto the chamber 2 with plates 3 and cone 6, the chamber 2 also being connected to one end of the expansion chamber 8 and the other end of said chamber being connected to the conical chamber 13 with plates 3 and double cone 14. The chamber 13 is in turn attached to the outlet pipe 12. Within the expansion chamber 8 are the reversely arranged coned chambers 16 and 17 the former having the spaced coned plates 3 and double cone device 14 and the latter having the spaced cone plates 3 and the cone plate 6. Between the chambers 16 and 17 is disposed the passage 18 for exhaust gases led from the chamber 16 to the chamber 17 Both chambers 16 and 17 are preferably arranged in the chamber 8 whereby the gases from the chamber 2 will first enter the chamber 8;
from thence they pass through the chamber 16' to the passage 18 and from thence to the chamber .17 from whence they pass into the chamber 8 and from the latter into-the chamber 13 to the outlet pipe 12. I
Referring to Fig. 12 in which another modified form of the complete mufiler is illustrated, the inlet pipe 1 having a chamber 19 is also connected in any suitable manner to the base end of the conical expansion chamber 20. Another conical chamber 21 with plates 3 and cone 6 is suitably attached to the truncated apex end of the chamber 20 and the base end of the chamber 21 has the base end of another conical expansion chamber 22 suitably connected thereto, the opposite 'end of the latter chamber being attac ed to the outlet pipe 12. I
Upon reference to Fig. 7 it will be seen that the conical mufiler plates 23 shown therein are slightly curved whereas the conical muffier plates 3 shown in Fig. 2 (which illustrates a similar arrangement of mufller parts to that shown in Fig. 7) are straight.
Instead of the mufiier plates being made conical they ma be dished as illustrated in Figs. 8 and 9, t e lates 24 shown in Fig. 8
being somewhat di erent in formation to the plates 25 shown in Fig. 9. Such plates 24 and 25 may be secured together by bolts 26 or other suitable means. End plates 27- and 28 respectively are provided for the arrangement of the plates shown in Figs. 8 and 9 and such end plates are attached to the respective adjacent plates 24 and 25 by bolts 29 or the like. Between such, plates 24 and 25 respectively are the gas passages 30; and in each said plates 24 and 25 are the openings 31. The plates 24 may be carried inachamber 32; and the plates 25 may be carried in a chamber 33. Plates 24 or 25 adjacent respec-.
tively the chamber 32 or 33 may be secured to the latter by means of bolts or other appropriate means. Both series of plates 24 and 25 are arranged in relation to each other in their respective chambers 32 and 33 so that a clear space 34 will be provided for entrv of exhaust gases into the passages 30 as well as the passages 35 between the interior walls of the chambers 32 or 33 and the adjacent plates 24 or 25 thereof.
It will be understood that the dimensions of the mufiler apparatus may be as desired and that any suitable number of chambers with associated spaced mufller plates ma be utilized. The assembly of the said cham rs with their plates oflers facilities for the expansion of exhaust gases in passing therethrough, and as such gases are also allowed further expansion either in the chamber 8 or in the expansion chambers 20 and 22 the spent exhaust gases are enabled to leave the outlet pipe 12 with minimum noise whilst the free passage of gas through the mufiler from the exhaust pipe of the engine is enhanced.
What I claim as m invention and desire to secure by Letters atent is 2- 1. A mufiler comprising a cylindrical chamber with ends of truncated conical shape one of which is adapted for connection to an exhaust pipe and the other terminated in an open tail iece, a nest of concentric partition members tted in said chamber adjacent one of its truncated conical ends and arranged in spaced relation to form concentric gas passages of different lengths, and a coned spreader plate fitted within the chamber adjacent the other truncated conical end.
2. A mufiler according to claim 1, in which the partition members are of frusto-conical shape graduated in dimensions and assembled in concentric order with their open truncate ends relatively disposed in conical order thereby offering a full section opening for the entry of gas into or out of gas passages between such members.
3. A mufiler according to claim 1. in which the partition members consist of dished plates.
4. A mufiler according to claim 1, in which the partition members are of frusto-conical shape graduated in dimensions and assembled in concentric order with their open truncate ends relatively disposed in conical order, a spreader is located centrally of and at one en of the partition members and facing the separate apertures thereof, and the larger ends of the partition members are disposed in the same plane with one another when said members are assembled.
5. In and for a mufller, a tubular nose piece having one end thereof adapted for connection to an exhaust pipe, a head of truncated conical shape at the other end thereof, a lurality of frustro-conical partition members arranged in concentric and nesting relation with each other and having gas passages between them of progressively increasing crosssectional area, the open truncated ends being dis osed in conical order and the opposite en s being disposed in the same lane with one another, substantially as an for the purposes set forth.
In testimony whereof I afiix my signature.
