U'NITED STATES Parser orri'e ODIN HENRY WILSON, OF. CEDAR VALE, KAN SAS.:

Application filed September A all'whom it may concern:

Be itknown that I, OLINH". WV'rL'soN, a citizen'of'theUnited Stat'es, and a resident of Cedar Vale,,in the county of Chautauqua and State of Kansas, have invented certain new and usefullmprovements in Cut Outs,-. of which the following is a specificae tion.-

inventionrelates to exhaust release devices especially adaptedffor use on internal'fcombustion engines.

Briefly. stated an important object of. this invention is to provide an*- exhaust release device. having simple means, whereby the same may. be opened'to permit of the. free and unobstructed movement of the exhaust gases to the atmosphere without the necessity of first traveling through the mulil'er and without the necessity of" making objectionable bends.v

A further object of' the invention is to provide simple means whereby the improved cut out. device may be incorporated in. anexhaust line either duringthe manufacture:or assembly of an automobile or at any time thereafter without inconveniencev or the exercise. of unusual skill.

A-further objecti's. to provide a cut out device which is, of. highly simplified construction,v durable in; use and cheap to manufac-ture.

Other objects and advantages will be apparent during the course of the, following description.

In the accompanying. drawing forming a part ofthis application and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a. perspective of the improved cuteout device applied;

Figure 2 is a vertical transverse sectional.

viewthrough the improved: cut out device applied;

Figure 3 is a vertical transverse sectional haust-pipefrom the forward portion of theexhaustpipe: the' said rear portion of the pipe-may be; designated the 'muiliei pi-pe+ In carrying out the invention I provide co -act-ing disleshaped sections 11 and 12,

havin their oaaosedsides flatl' in abutment' and provided wit-h lugs orearsv lg and 14, respectively, for thereceptionyof a bolt 16" by means of which the; disksor plates are hingedly connected.

The exhaust line- 5 and consequently the section 11 which is rigidly secured thereto are relatively stationary since the exhaust line is supported by abracket 18 secured to any stationarypart'. of" the vehicle,- such" as the frame by means of a fastening device 20. The co-actirig sections 11 and 12am formed with openings 22 and: 23 adapted forregistration so asto establish communication between the'exhaustpipe fr and the muflier pipe 9; It willbe seenthat the-exhaust conducting members 5 and 9 extend through bosses 25 and 26 and are rigidly secured thereto by set" screws and 28 or other suitable fastening devices;

The disk-shaped member 12which is the main movable member of the structure is limlted 1n lts movement in one direction by means of an arcuate stopan'd guideflange- 30 integral with andv extending acrosst-he lower portion of the section 11 after the manner ofa chord but located in spaced relation to the flat face of the section-11. \Vith reference to Figure 2 it will beseen that the inner surface of the flange 32 is inclined'or beveled'soas to forma' gradually narrowing groove 01: channel" for the reception of the bevel'edlower edge of the movable. section 12. It is. thus seen that when the movable section returns to its normal position with the open'ngs and in registration the beveledlower edge of the movable section will be engaged with the beveled inner side of the flange 30 so that the opposed flat faces of the sections 11 and 12 will be urged into practically gas tight connection with each other. In this manner the escape of the exhaust gases between the sections 11 and 12 is prevented. Therefore, the flange 30 not only serves asa means to limit the movement of the section 12 in one direction but also as a means to insure a practically gas tight connection between the disk-shaped members 11 and '12.

The movable section 12 is provided with V a radial arm 36 having connection with a coiled spring 37 by means of which the openings 22 and 23 are urged into registration. One end of the coiled spring 87 may be-anchored to a stationary portion IO of the vehicle.

The section 12-may be swung on itspivot by a foot pedalconnected to a cable L6 and when the cable 46 is operated the section 12 of the disk 12 scrapes away any'dust, dirt,

grease, oil or the like that may have been deposited on the flat face of the disk 11' and the edge of the disk 11 likewise'scrapes'the flat face of the disk 12 to maintain the contacting faces clean and smooth.

However, when the sections are not in registration or are in position as illustrated 'in' dotted lines in Figure 3 the products of coinbustion will exhaust freely out of the exposed end of the exhaust pipe 5. It will be seen that when the cut out is opened the products of combustion do not have to make sharp bends or turns at the cut out'and consequently carbon deposits in the cut out are reduced to a minimum and movement of the products of combustion is not in any way obstructednor retarded. I

In order to provide for the escape of'the exhaust gases at all times and especially during the swinging movement of the section 12, this section 12 is provided witha series of concentric arcuate openings 40 located in the portion of the section 12 that traverses the opening 22. The openings 40 are of the cross sectional form shown in Figure a so that the strength of'the section 12 will be preserved while the escape of the gases is facilitated.

The invention forming the subject-matter of this application may be incorporated in 7 an exhaust pipe at any time without the exercise of unusual skill or without elaborately changing the construction of the vehicle.

In the form of the invention illustrated in Figure 4 the sections and 61 may be provided adj aoent the cut-out with bends 66 and 67 so that when the sections are outof registration the products of combustion will be directed downwardly toward the ground so as to reduce the fire hazard to a minimum.

Figure 2 illustrates that the section 9 has one end flared or enlarged as indicated at '73, and received within a socket 75in one end of the muffler. A suitable strap or clamp 7 6 may be secured about the socket 7 5v so as to hold the enlarged or sphere-shaped portion 7 3 within the socket.

I claim a l. A cut-out comprising co-acting diskshaped sections having their opposed sides flatly in contact and provided with openings adapted for registration, means pivotally connecting the disk-shaped sections, one of the sections being provided with a combined stop and guide flange extending in spaced relation across its face and arranged in the path of travel of the other disk-shaped section, spring means urging the openings in the disk-shaped sectionsinto registration, an exhaust conducting member connected to one of 'the' disk-shaped sections and having means whereby the same may be universally connected to a muffler.

2. The combination of an exhaust line d1- vided' into two sections, a pair of cor-acting disks having their opposed faces flatly in contact and having their outer sides rigidly connected to said sections, one of the sections being stationaryiand the other being mov- -able,,a inuflier having universal connection with the movable section of the exhaust line, i

and means-whereby to limit the movement of one OfStIld disks with relation to the 8. In a cut-out, a stationary diskand a movable disk pivotally connected to the sta tionary disk, said disks having central openingsadapted for registration, said movable disk having a series of concentric arcuate o enin svin the ortion of the movable disk that traverses the central opening of thestationary disk, said arcuate openings being" tapered in cross section.

4;. In a cut out, a stationary disk and a movable disk pivotally connected to the stationary disk, said disks having central openings adapted for registration, said movable disk having a series of openings in the portion" of the movable disk that traverses the central opening of the stationary disk;
