S ILENCER CONSTRUCTION Filed Nov. 3, 1939 Patented May 13, 1941 UNITED STATES PTENT 2241562; SILENCER CONSTRUCTION Floyd E. Del-emer, Detroit, Mich. Application November 3, 193 9, Serial No. %2,773
(o. lal-61) 4 Claims.
This application relates to exhaust gas silencers, particularly for automobila engines, and more particularly relates to the problem of draining of condensed moisture from within the silencer.
It is now the practice to provide in silencers a drain hole in the shell. Commonly the dran holes are formed by drilling holes into the shell from the outside of the shell after the assembly of the silencer. For several reasons this prac tice is objectionable. When a shell is of multi-ply Construction, the pressure of the drill in many instances causes separation of the plies. In the use of the silencer, the draining condensate is blown inwardly by the rush of air into and around the interior of the silencer, and thus forms a rust streak around the silencer at the hole.
The object of the invention is to provide a novel drain hole construction particularly adapted for multiply shell silencers.
The invention is shown as embodied in a silencer shown in the appended drawing. In this draw- Figure 1 is a cutaway elevation drawing of a multiply silencer having a drain hole of the invention;
Figure 2 is an enlarged fragmentary longitudinal view of the drain hole per se;
Figure 3 is a cutaway end view.
The silencer herein shown consists of a shell of two plies o and I I surrounding a through passage tube |2 having inlet and outletends I4-l5 near the headers which close the shell and through which the tube passes.
Near the outlet end of the silencer is the drain hole Construction IS which consists of two nested annular flanges projecting outwardly from the shell these being formed by piercing a hole through both plies simultaneously when they are nested and before; the end headers are assembled with respect to the shell.
By forming the holes from the inside, there is no tendency to cause separation of the plies. The outwardly projecting annular fianges form a sump around the drain hole to insure proper drainage and to prevent drainage from being blown back into the silencer.
The interlocking annular flanges also operate to prevent relative rotation and longitudinal shifting of the plies, and this is particularly useful during the assembly of the headers with respect to the shell.
Now having described the drain hole Construction herein described, reference* should be had to the claims which follow for a determination of the invention.
I claim:
1. An automobila exhaust gas silencer outer shell'consisting of two telescoped plies having alir'ed holes, the inner ply having an outwardly projecting annular flange surrounding the hole therein and disposed within the hole of the outer ply.
2. An automobile exhaust gas silencer outer shell consis ting of two telescoped plies having alined holes, the inner ply having an outwardly projecting annular flange surrounding the hole therein and disposed within the hole of the outer ply, the latter having an outwardly projecting annular flange surrounding the hole therein and also surrounding the annular flange surrounding the hole of the inner ply.
3. An automobile exhaust gas silencer outer shell consisting of two telescoped plies having alined holes, the inner ply having an outwardly projecting annular flange surrounding the hole therein and disposed within the hole of the outer ply, the flange engaging the edge of the hole of the outer ply.
4. An automobile exhaust gas silencer outer shell consisting of two telescoped plies having alined holes, the inner ply having an outwardly projecting annular flange surrounding the hole therein and disposed within the hole of the outer ply," the latter having an outwardly projecting annular flange surrounding the hole 'therein and also surrounding the annular flange surrounding the hole of the inner ply, the flanges engaging each other. i
