gases strike against the va lve .a n d {are'deenlarged 'size.';acts somewhat as z'aj driuii': o'r'i resonator, thus serving t ammate the" trial line of'trav el of thegases, mabi wth By'means of this construction the several parts .of the cut-out, and particularly the valve, are readily accessible for the purpose of replacement or repair. The cut-out as a whole can be removed by loosening the holdin bolts without disturbing the position or.

' alinement' of the adjacent -ends of the 'exhaust pipe. If-desired to clean the valve it is only necessary to remove the upper portion of the drum and the valvecan be lifted out without loosening or detaching any other parts. The cut-oil pipe can be bent in any desired direction, but preferably the gases or' vapors are exhaustedrearwardly in line with the muffler, so that dirt and dust will not'enter and clog the valve seat or the circumference of the valve plate, which is. also finished to seat tightly upon the valve seat. Since the valve seat is removable, access may be readily had to the drum without disconnecting it from the exhaust pipe line by loosening the cut-off pipe. l-

-It is obvious that the lever 17 which actu-- ates the valve may be set at any desired angle with respect to the valve. It is obvious also that varioustother changes with-. in the skill of the mechanic may be made in the details of construction without depart ing from the spirit of the invention, provided the means set forth in the following claims be employed.

I claim as my invention:

1. In a muffler cut-out the combination with a chamber forming part of the exhaust pipe, of a cut-out pipe detachably secured to and communicating with said chamber and provided with a flange forming a valve seat and a valve mounted in bearings formed partly in said cut-out pipe and adapted to enga c said valve seat. to close said pipe- 2. n a mufiier cut-out the combination with a resonator comprising cylindrical end portions secured to the exhaust pipe and a 'semi-cylindric central portion having a larger diameter than the end portions and communicating with said end portions through a constricted opening having the same diameter as the exhaust pipe, of a cutoff pipe secured to and communicating with the resonator, a valve controlling the opening into said cutoff pipe, said cutoff pipe being provided with a flange wherebythe same is secured to the resonator, said flange being provided with a. bearing for the valve and forming a seat for said valvein its closed position.

3. In a'mufller cut-out the combination with a resonator-comprising end portions of a diameter not less than the diameter of the. exhaust pipe and a central portion of larger diameter than the exhaust pipe, a cut-out pipe commumca't-mgw-rth said resonator, a valve in said resonator secured to a stem rober having a"cros's-sectional area tatable in bearings formed-partly in said resonator and partly in the wall of said pipe at the junction of said resonator and pipe, means for normally holding said valve in position to close the cut ofi pipe, said valve in itsclosed position being arranged below the line of the exhaust pipe.

4. In a muflier cut-out the combination with a chamber forming part of the exhaust pipe, of a cut-out pipe communicating with said chamber and provided with 'a flange whereby said pipe maybe detachablv secured thereto, a valve in said chamher having its stem seated in bearings formed partly in the wall of-said chamber and in said flange, and means for securing said cut-v out to the exhaust pipe whereby it maybe removed without disturbing the adjacent ends of'the exhaust pipe, substantially as described.

5. In a mutiler cut-out the combination of a cut-out pipe communicating with the exhaust pipe lineand having a larger diameter than the exhaust pipe, of a valve 'seat onsaid cut-off pipe, a valve'comprising a valve plate, and a'removable valve stem, a spring secured to'said valve stem for nor mally holding. the valve on its seat, means for adjusting the tension of said spring, and

a ,lever-for actuating said valve, substantially as described.

6. A mufiler cut out-adapted to be attached to an exhaust pipe, comprising a chamber having an opening on one side thereof, a cut out pipe having a. bore in communication with, and of less dimension than said opening, the end of said out out pipe removablyfastened to said chamber and closing said opening and provided with a valve seat, and a valve normally resting on said seat to close said out out pipe and disposed out of line of the fluid passing through said chamber and having'a pivotal connection disposed between said pipe and chamber.

7. As an article of manufacture, a, mufller cut-out comprising a three chambered cast ing having a common bore, and having an inlet and an outlet at opposite ends thereof, the end chambers having a crosssect-ional area greater thanthe corresponding area of said inlet and outlet and the middle chamreater than the corresponding area of said end chambers and having the openings thereto equal tothe inlet and the outlet and a valve controlled outlet from said middle chamber.
