Specification of Letters Patent.
Patented Feb. 29; 1916.
Application filed October 4, 1918. Serial No. 793,862
To all whom it may concern:
Be it known that we, JAMES S. JoHNs'ro and MILLARD L. JOHNSTON, citizens of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Mufliers, of which the following is a specification, reference being had therein to the accompanyin drawing.
Our inventionrelates to a mu er, and we declare the following to be a full, clear, concise and exact description thereof suflicient to enable anyone skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the Specification. v
The object of the invention is to provide a simple efficient mufiler for use in connection with internal explosive engines. The mufller is constructed to conduct the exhaust, as it comes from the engine, along a tortuous path that is adapted to give said exhaust a spiralwhirl, whereby the sound of the escaping gases will be completely mufiled without causing any back pressure on the engine.
Other features will be observed by referring to the drawings in which:
Figure l is a central section of the mufiler: Fig. 2 is a central section of a modified form of the mufl ier; Fig. 3 is a pers ective view of a tube employed in the mu er; Fig. 4 is a central section of a modified form of the mufiler, drawn on a somewhat smaller scale than that of the foregoing figures.
Referring more particularly to the drawings, there is a center tube 1 which has a bore larger indiameter than the tube con-. necting the tube 1 with the exhaust pipe of the engine, so that the exhaust will not be impeded in any degree, when the same enters the tube 1-. The tube 1 is provided with apertures 2-2 and 33. The apertures 2 are disposed opposite each other at the ends of a diameter, which is perpendicular to a diameter at the ends of which are disposed the apertures 3. Each two sets of the apertures 22 and 3-3 are inclosed by a cylindrical casing 4 adapted to form with the disks 5 and the end members 6 and 7, the chambers about the tube -1. The disks 5 are provided with the central apertures 9 and circumferential peripheral grooves 10-10, in which fit the corresponding edges of the casings 4:. The end members 6 and 7 have bosses 11 and 12, respectively and are held in place on the tube 1 by nuts 13 and 14, which are threaded to the corresponding ends of the tube 1. The end member 6 is also. provided with an aperture 15 normally closed by a member 16. The member 16 is drawn outward, whereby to open the aperture 15, by means of a cord or other suitable device 18 that is attached to a lever 19 located within convenient reach .of the chaufieurs seat. The mufiler is easily assembled by first disposing the disks 5 and end members 6 and 7 upon the tube -''1, placing-the casings 4, so that their'edges will engage the corresponding grooves of the disks 5 and then mounting the nuts 13 and 14 upon the tube -1-.
The operation of the muflier is effected in the manner following: The exhaust from the engine enters the tube 1 at the end 20 and passes, as-indicated by the arrows along the tube -1 until it reaches the apertures 2-2, its further progress along the tube 1 being prevented by the wall 21, whereupon, the exhaust enters the chamber 22, which allows the said exhaust to expand therein. From the chamber 22, the exhaust reenters the tube 1- by way of the ports 3-3, and thence from the tube as when the automobileis ascending a hill or under a similar circumstance, the chauffeur manipulates the lever 19 and thereby opens the aperture 15 for the free passage of the exhaust to the atmosphere.
Fig. 2, shows a mufller substantially similar in construction to that of Fig. 1. The casing 30 is secured in place by grooves 31 and 32 in the end members 33 and 34, respectively. The chambers 35, 36, and 37 are formed by the disks 38 and 39,'which are held in position along the tube 40 by set screws or like means 41 mounted in the bosses 42 of the disks 38 and 39 and adapt ed to engage the surface of the tube 40. The end members 33 and 34 are held in position by the nuts 43 and 44 screw mounted to the ends of the tube 40. The means for permitting the exhaust to escape without passing through the tortuous path, which is similar in this instance to that of the former.
2 by the coiled spring 49, which bears at one end against the member 50, whose opposite ends are secured to the nut 44, and the other end against the pin 51. The rod 48 is actuated longitudinally, wherebyto move the valves 47 away from the ports 46, so as to effect a straight passage to the atmosphere for the exhaust, by the member 52 having an arm 53 and held to the rod 48 by the pins 51 and 54. The member 53 is connected by a chain or other device 55 with a lever 56 located near the seat of the chaufl'eur.
Fig. 4 illustrates a further modification embodying a central tube 60 which comprises the member 61 having. integral or otherwise secured thereto a' disk 62. The said member 61 is also provided with partitions 6363 and is adapted to detachably hold the adjacent ends of the members 64 and 65, which are provided in an integral manner or otherwise, with the end members 66 and 67, respectively. The casing 68 is assembled by disposing its edges in the grooves 69 and 70 of the end members 66 and 67. The mufiler is held in assembled position by the rods 71 and the nuts 7 2. In operation, the exhaust enters by way of the end 73 and proceeds along the member 64 to the ports 74-74, oppositely dsposed; to the chamber 75; to the member 61 by way of the ports 7 67 6; t0 the ports 777 7; to the chamber 78; to the member 65, by way of the ports 7 97 9, and out through the end 80 of the tube 60 to the atmos here. This last described construction is o importance because of its knockdown feature and the quick manner in which the parts can be as sembled, so also may a like remark be made concerning the foregoing constructions, to a somewhat lesser extent.
The parts of the mufiier shown in the various modifications may be duplicated to a greater or less extent in accordance with the,
