MAC ALBERT CAMPBELL, OF KNOXVILLE, TENNESSEE.

CUT-OUT.

Application filed April 12, 1924.

To all whom t may concern:

Be it known that I, MAC ALBERT CAMP- BELL, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Cut-Outs, of which the following is a specification.

This invention relates to a cut-out for motor vehicles, the general object of the invention being to provide. a cut-out which is normally closed by a spring pressed valve so that there is no danger of leakage when the cut-out is not being used.

Another object of the invention is to make the outlet of the device in the form of a bell which will give a volume to the noise made by the escaping gases.

This invent-ion also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure lV is a. sectional view showing the invention in use.

F igure- 2 is a section on line 2-2 Figure 1.

Figure 3 is a section on line 3 3 of Figure 1.

In these views, l indicates a T-shaped casting which is adapted to be placed over the ends of the exhaust pipes 2, the casting being held on these pipes by the screw caps 3 which engage the tapered packing rings 4 for preventing leakage between the pipes and the casting. The third opening of the casting is provided with a valve seat 5 for receiving the valve head 6, the stem 7 of which passes through the top of the casting l where it receives a spring S-which tends to hold the valve in raised position, the spring engaging a washer 9 ou the end of the stem. A lever l0 is pivoted to a post 1l carried by the casting and is arranged to engage the top of the valve stem to depress the same to open the valve when the pedal 12, which is pivoted to the other end of the lever l0 and which passes through the floor board of the vehicle, is depressed. A notch is made in said pedal for engaging a portion of a plate lll for holding the parts in position with the valve open so that it is not necessary to keep the foot on the pedal. A bellshaped member l5 fits over the exhaust of the casting* so as to cause the escaping gases to make a pleasing noise as they pass from the cut-out.

From the foregoing it will he seen that I have provided a simple cut-out which can be .easily and quickly put in position and which is so connected with the exhaust pipes that leakage cannot take place. The spring aetuated valve will hold the cut-out closed until the valve is depressed by the pedal. The bell member gives volume to the sound and gives it a pleasing tone.

It is thought from the foregoing description that the advantages and novel features of my invention will he readily apparent.'

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim isz- A cut-out for a motor vehicle comprising a casting having screw threaded ends, threaded caps engaging the ends for holding the casting to the exhaust pipes of a vehicle, packing rings engaged by the caps, a spring pressed valve for closing the exhaust of the casting, a foot lever pivoted to a part on the casting and having a part resting on the top of the valve stem for opening the valve and a bell-shaped member connected with the outlet of the casting In testimony whereof I aiiix my signature.

MAC ALBERT CAMPBELL.
