TO READING STANDARD COMPANY, A CORPORATION OF N SYLVAN IA MUFFLER CUT-OUT.

Specification of Letters Patent.

Patented Feb. 25-, 1.908.

To all whom it may concern:

FER, citizen of the UnitedStates, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Im rovements in Mufiler Cut- Outs, of which the following is a specification.

This invention has relation to -cut'outs for mufllers, and it consists in the novel arrange.

ment of its parts as hereinafter shown and described. 1

Strictl speaking, the cut-out is not a portion of t iemufiier but affords a means for connecting or communicatin the exhaust ipe of an engine with a In er. The cutout is in the form of afitting and is provided at one-end with a port for connection with the exhaust pipe and at its opposite end with.

a port against which a valve-is designed to operate.- The fitting is provided at .a point intermediate of its ends with a mufiler port for connection with a mufiler. .The channel throu h the-fitting is distorted or inclined slight? its lower portion is curved toward the said ort in order to relieve the valve at the iowerend of the fitting from excess pressure when closed. i

In the accompanying drawing, the

with an exhaust pipe and a mufller.

The 'muflier .1 is of any usual form and the fittin 2 is interposed between thesaid mufiler and t 1e exhaust pipe 3; The upperend-ofthe fitting 2 is non-circular, as'at 4, andis provided with an opening which communi- 'cates withthe pipe 3. At its opposite end the fitting is provided with an ope '5;

Said openlng is provided with a' seat 6. e lugs 7 are Located upon the outer'side of the fitting 2 and the'shank .9 is "ivoted to said lug by means of a pin "8; e valve 10 is mounted upon the shank 9 and is. adaptedto close against. the seat 6 of the opening 5.

y away from the lateral port,-'and at outlet ports,- said The element llfis attached at one end to the Be it known that 1, WILLIAM G. SCHAEF-f shankB and'is'adapted, when'drawn, to hold the valve:10 -closed against the seat -'6. One

- end of the spring 12 is attached to a stationary point and its other end is attached to the shank 9. 'Th'esaid spring is under tension and has a tendency to hold the shank 9 and the valve 10- away from the seat 6. All of the .openingsof the fitting are of substantially the same lateral dimensions, and the chan-' nel throu h the fitting is slightlydistorted or-incline away from the lateral opening of the'fittin and atitslower portion is curved toward t e said lateral o ening. The ob-' ject in providing the cined channel as specified is to relieve the valve 10 and shank 9 from the direct pressure or force of the ex-v haust when thesaid valveis closed, and the said exhaust is introduced into'the Inufiler.

Thus the valve will not be vibrated against its seat-with inju to the valve and seat.

What is claime is Ainufiier cut-out comprising afitting having parallel inletand outlet ports, a

swinging valve adapted to close the outlet port, a muffler port located between and substantially perpendicular to said inlet and outlet orts, all of said ports being of sub s'tantia ly the same area, said fitting having a channel leadin from the inlet port tothe channel being bent at an intermediate point andinclined at an angle to said parallel ports and then curved arou- .ately into alinement with said muflier ort,

whereby the outlet port is relieved o the direct pressure or impact of the exhaust ontering the inlet valve.
