MUFFLER.
Application led September 15, 1920. Serial No. 410,466.
T o all whom it may concern.:
Be it known that we, THOMAS E. GENTH- NER and ADELBERT L. STEVENS, citizens of the United States, and residents of Boston, in the county of Suffolk, in the State of Massachusetts, have jointly invented acertain Improvement in Mufflers, of which the followingis a specification, reference being had to the accompanying drawings.
This invention relates to mulflers for use with internal combustion engines and more particularly to those used with the engines of motor boats, in which provision is made for the circulation of sea water through 'the water jacket of the engine; our object being to provide a specially simple and cheap form of muffler whichmay he readily adjusted to receive the intake and discharge pipe connections.
l'n order to explain our invention clearly we have provided the annexed drawings, in which the Figure 1 is a side elevation of a muffler embodying our present improvements and Figure 2 is mainly a vertical,
sectional, view taken at the line 2 2 of Figure 4. 'Figure 3 is a top or plan view of the complete muffler. Figure 4 is a horizontal, sectional, view taken at the line 4 4 of Figure 1. Figure 5 is an elevation of one of the members of the muffler detached and partially broken away.
Referring to these drawings, the reference numerals 10 and 11 indicate the two companion members of our new muffler, said members being exactly alike as to size and form excepting only that provision is made for locating a suitable gasket or packing between the meeting, flanged, edge portions of the said members; one of sai. edge portions being rabbetted, as at 12, to receive a gasket 13, the edge portion of the other member being suitablyturned down to fit into said rabbet, as is clearly seen at 14 in Figure 2 of the drawings.
The member 10 is provided near its upper portion with a circumferential opening and a boss 15 which is adapted to receive a pipe 16 which leads from the engine exhaust, and the member 11 is provided near its lower portion with a like opening and a boss 17 that is adapted to receive a pipe 18 which leads overboard from the muffler. 19 denotes an opening in the dome of member 10 into which is screwed a pipe 20 which leads from the water-jacket of the. engine, and 21 denotes an opening in the bottom of' member 11 into which is screwed a water p1pe 22 which leads overboard.
Vhen the two described members 10 and 11 are assembled, as seen in Figures 1 and 2, they are clamped together by means of a centrally located bolt 23 and nut' 24,"this construction and relative arrangement of parts being such that, before the nut 24 is screwed home, the, members 10 and 1l may be adjusted rotatively, if necessary, in order` that the bosses 15 and 17 may be easily lined up with their respective pipes 16 and 18 instead ofbeing compelled to ben-d or otherwise adjust the pipe ends, as is often necessary when connecting up with the muffler.
`The member 10 is formed with a depending, integral, baffle-plate 25 which is of such length that it extends nearly to the bottom of the member 11 when said assembled, and the member 11 is formed with a like baffle-plate 26 which extends nearly to the dome of member 10 when said members are assembled (see Figure 2) each baille-plate being formed of two sections or portions that are at approximately right angles to each other and, when the two members 10 and 11 are assembled the apexes of `the said angles are spaced apart in opposition toeach other as is best seen in Figure 4 of the drawings.
When our described muffler is in service the exhaust products are discharged through pipe 16 into the said muffler and impin e against the opposing, inn-er, face of" ba eplate 25 and then pass kdown to and under, the lower end of said baffle-plate 25. The exhaust then passes upward, over the to of the baffle-plate 26 and thence downwar and is finally discharged through pipe 18. Meanwhile, the water from the water-jacket enters the muffle through pipe 20 and follows, mainly, the courses taken by the exhaust, as we have just described but, in order that the muffler may not become filled, and congested, by said water, we have provided one or more openings 27 in the baffleplate through which a considerable portion of the water may find a more direct escape.
It should be noted that, when the exhaust enters the muffle, it is discharged more or less forcibly against the angular walls of the baffle-plate 25 instead of against a flat plate, as is most common in devices of this general type1 so far as we are familiar with them. y The force of the impact of the incoming exhaust is thus relieved and bromembe-rs are llO ` ken up and the tendency to gradually wear structure ada ted to be secured toget er to.
form a cham r therebetween; a'. gas inlet and a water inlet in one of said members; a gas outlet. and a water outlet in the other of said members; a baille plate attached to each of said members adapted to partially divide said chamber; and means to rotatably adjust said members whereby said inlets and outlets may be relatively angularly arranged to align with pipes previously installed and adapted to coact therewith.
2. A muller of the class described consisting of two members of substantially like structure having pivotal connection with a device that normall serves to hold said members in adjustedY operative position; a gas inlet and a water inlet in one of said members arranged eccentrically with relation to said pivotal device; a gas outlet and a water outlet in the other of said members also eccentrically arranged with relation to said pivotal device; and a baille plate attached to each member of greater length than the de th of said member.
3. A mu er of the class described consisting of two members of substantially like structure. havin a. centrally disposed pivot adapted to firmy secure said members in a desired angular relative position; a chainber formed b the union of said members; a gas inlet and a water inlet in one of said members eccentrically arranged with respect to said pivot; a gas outlet and a water outlet in the other of said members also eccentrically arranged with respect to said pivot; and a baille plate attached toeach of said members so arranged as to divide that pgrtion of the chamber formed by its memand extend an ap reciable distance intothat portion of the c amber formed by the other member.
4. A muler of the class described consisting `of two members of substantially like structure, having a centrally disposed pivot adapted to normally firmly secure said members in a desired angular relative position; a gas inlet and a water inlet in one of said members; a gas outlet and a water outlet in the other of said members, said inlets and outlets being arranged eccentrically with respect to said pivot; and a baille plate attached to each member so arranged as to overlap that of the other member.
5. A muiller of the class described consisting of two members of substantially like structure havin a centrally disposed pivot about which eit eiof said members may be angularly adjusted and which'normally constitutes a fastening means for said members; a gas inlet and a water inlet in one of said members; a gas outlet and a water outlet in the other of said members, said inlets and outlets being eccentrically arranged with respect to said pivot; a baille plate attached to each of said members so arranged as to overlap that of the other member; and relief ports in each of said bale plates.
