MUEELEE Application meaJanuary a,v 1931. serial No. 507,444.

This invention relatesto muiiiers'` for internal combustion l engines and is an improvementupon .thef muffler disclosed in our copending application tiled May 2, 1930, Serial No. 449,313. j Likethe invention disclosed in the application mentioned, the presentv invention has for its primary object the provision of a device which may be attached to the exhaust of an internal combustion engine to mutile the sound `of the exhaust, and to absorb the exhaust gases, so that little if any Vgas will reach the atmosphere.

The present invention further has for an object the provision of means to simplify and cheapen the construction of the muiiler, and

Y lto materially add to its efficiency.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

Figure 1 is a vertical longitudinal sectional view illustrating the invention.

Fi ures 2, 3, 4 and 5 are sections taken respectively on the lines 2 2, 3-3, 4 4 and 5-5 of Figure 1. y

Figure 6 is an enlarged fragmentary sectional view through` the upper end of. the valve cylinder illustrating its communication with the atmosphere. u

Referring to thedrawingsin detail wherein like characters of reference denote corresponding parts, the reference character 10 i11- `dicates the casing of the muiiier which is provided withl a removable top or cover 11, the

' latter being held in place by bolts or screws 12. Preferablyl formed integral with the muffler casing is a conduit 13, having one end in communication with an inlet port 14, which is adapted for communication with the'exhaustof an engine. The lower inner end of the conduit 13 is in communication with a valve casing 15, through the medium of a short pipe section 16, a check valve 17 being arranged within the casing 15. A removable plug 18 extends through the valve casing 15. Also in communication with the valve casing V isadischarge nozzle 19. This noz- ,zle yis closedvat its outer end "and isprovided with spaceddischarge openings 20 `which Vare arranged at an angle of ninety degreeswith respect toone another and so disposed `that exhaust gases passing from the nozzle through these openings `will be directed downwardly. The muffler casing 10'is partly filled with water or other suitable liquid, the

level of which is indicated at21, and for this purpose, the casing 10 is providedwith a lllng opening 22 which is normally closed by a plug 23. A drain cock 24 is in communication with the casinglO below the liquid level line. y L

Extending upwardly from the bottom of the casing is a delector plate 25. This plate extends upward, substantially to the liquid Y level line andas rshown in Figure 2 of the l drawings, the side edges of the plate terminate short ofthe side walls of the casing 10.

Arranged within the casing 10 is a pipe or conduit 26. One end of this pipe or conduit is attached to the top 11 as shown at 27,

While the opposite lower end of thepipe is attached to the bottom of the casing through the medium of a lug 28 and a screw 29. The lower end of this pipe is closed by a valve 30 which is carried at the out-er end of an arm 31. This arm is pivotally mounted as "shown at 32'and the valve 30 carries a stem 33 which is freely movable within an opening 34 provided in the arm. A securingnut 35which is mounted upon'the stem 33, acts to hold the parts associated, but this nut is so spaced from the arm 31 as to permit of a slight movement and provide for the perfect seating of the valve 3() against the end of the pipe 26.A

The pipe 26 is providediwith a partition "36 which terminates short of the lower end of the pipe and divides the pipe into a passage 37 and a passage38, the adjacent endsV 7 ating axiallyV within 'the bushing z' Vin position `for use.

whose other end is in communicationwith the atmosphere.

The arm 31 is pivotally mounted as shown at 32 betweenspaced ears l2 whicliextend from the pipe 26, while also extending Afrom this `pipe is a rigidarin i3 whose outer end carriesa cylinder 14 within which is positioned a bronze or other bushing 4-5.'

46 .which is bored as indicated.;N ceive a stationary p'ston 4S, the, ,Y o carried at the lower' end of a stein i9 which extends from tl'ieupper end of a capO.-

This` stem i9 is hollow sowas to providean Lair passage 51, the upper end ot'which coinmunicaf'es with a .hollow screw 1 52' which the liquid, asubmerged separating lchamber passesthrough the stem il? .and acts to retain The. hollow screw 52 further. provides. a passage which isin comvmunicationgwith Va. pipe 53 attached( tothe cap' 50 .as shown at 54. y

The v inner Yend of the passage 51 .oil the stem i9communicates with a valve chamber 55 provided iii the piston d8, onel end of this chamber beingclosed by a plug'dwhich is provided lwith arestricted opening 5'5".

` VVThe muffler casing is provided with drain opening 58 which is normally closed by'a plug-,59, and with apertured ears or lugs 60, by means of which itV may be secured Exhaustgases ent r the port 14 and pass downward through vconduit: 13, the valve 1'? and downward and outward vthrough the nozzle 19. The gases escaping fromthe nozzle strike thede'liector plate and pass upward through and out of the liquid, rising tothe top of the casing 10 and entering the passage 37 through-the the mufiler through flip o enino' 40. These ases ass downward through the passage 37 and i'oice the valve from its seat, so that water carried into the passage 37 with the gases is separated this point and passes outward into the mufller casing. The separated gases pass upward through the passage 38 to the atmosphere in a puriiiedstate. The. parts are so proportioned that compression of air within Athe hollow rod i6 is just suilicientto balance the operation of the valve 30, theV compressed air acting to seat the vvalve 61 within'the valve chamber 55. Upon closing movement oi' the val-veBO, the valve 61 willbe exhausted so that sufficient air will be drawn into the rod 46 for the next compressing operation.

The lower end ofthe rode-6 is biiiuicated Aand has mounted therein a roller 62 which Vbears upon the upper edge of the arm 31,
