GUT-OUT VALVE.

Specification of Letters Patent.

Patented May 14, 1918.

Application filed. June 5, 1916. Serial No. 101,821.

To all whom it may concern:

Be it known that I, GEORGE H. TABER, a citizen of the United States residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Cut-Out Valves of which the following 18 a full clear, and exact description.

This invention relates to certain new and useful improvements in cut-out valves. My improved valve is particularly adapted for use on automobiles to cut out the muffler. All valves of this sort are subject to extreme conditions in their use and when of the usual construction are quite likely to get out of order.

Vith my improved valve, no chains pulleys or similar devices are needed to operate the valve. In addition the valve is so constructed that it can be opened to any desired extent and will remain in the position in which it has been set by the operator without the use of locking pedals or catches. Other-objects of my invention reside in the provision of a valve which is self-cleaning and grinding and in which the sprlngs are so placed that they will not lose their temper and strength due to the hlgh heat of the exhaust gases. Other objects of my invention will be set forth in more detail in the accompanying specification and more carefully pointed out in the appended clalms.

In the drawings- I Figure 1 shows a central sectional view of the valve in position below the floor boards of an automobile.

Fig. 2 is a sectional view taken on line 22 of Fig, 1 and looking in the direction of the arrows.

Fig. 3 is a sectional view of Fig. 1 taken on line 3-3 looking in the direction of the arrows.

In more detail 10 is the central body portion of the valve. A branch 11 extends into the body and is provided with a set screw to secure the exhaust pipe 12 in position. Suitable lugs 13 are cast inside the branch 11 to prevent the exhaust pipe from being slipped too far into the valve. Diametrically opposite the body portion from branch 11 is a second branch 14 adapted to receive a muflier pipe 14*. The pipe is held by a setscrew and lugs 13 prevent the muifier pipe slipping too far into the branch. The branch 13 or tail pipe of the device is smaller in diameter than the inlet branch. This construction permits, in certain cases, the use of the muflier to be done away with as the central body portion 10 acts as an expansion chamber for the exhaust gases and the small tail pipe with the rest of the device acts in itself as a muffler.

The central body portion 10 extends downwardly below the branches 11 and 1d and is faced off at 15 to closely contact with a port plate 16 which is bolted to the body portion 10 by bolts 17. The central portion 18, of port plate 16, is provided with a number of sector shaped ports 19there being three of these ports as shown by the dotted lines in Fig. 3. Ofcourse any number of ports may be used. The port plate 16 is I centrally bored out to form a lower bearing for a shaft" 20 which extends upwardly through an axially alined bearing 21 in the body portion of the valve. To the lower end of this shaft just above the port-plate is pinned a valve member 22 having a flat lower face in contact with the upper face of the port plate and having a plurality of sector shaped ports 23. By turning shaft 20 these ports 23 may registration with ports 19 in port plate 16. In this way the cut-out is opened or closed. In order to direct the gases toward the port plate I provide a deflector baffle plate 2% which is cast integral with the central body portion of the cut-out and which also aids in the mufl'ling efiect of the valve when the ports are closed.

In order that the valve member be kept in close contact with its seat on the port plate and in order to hold the valve in any desired open or shut position I provide the following parts:

The port plate has two outwardly extending lugs 25 to which are attached springs 26. These springs at their upper ends are attached to an are shaped equalizer bar or bridge piece 27. This equalizer bar loosely surrounds the shaft 20 and rests upon a pin 28 secured to this shaft. The downward pull of the springs pulls the equalizer bar downwardly and this bar in turn through pin 28 and shaft 20 presses valve 22 against its seat. With this construction, if dirt should become lodged between the valve and its seat, by oscillating the valve a few times the seat will be cleaned. In addition the friction between the valve and the seat 18 sufficient to hold the valve open or part way open as desired closed or without the use of be placed in or out of any locking devices. To turn the shaft 20 and operate the valve I preferably extend the shaft 20 through the floor boards of the automobile and through a suitable floor plate 30. To the upper end of the shaft a kick pedal 31 is secured by a set screw. The operator of the machine by kicking this pedal 31 can open or close the valve. In order to limit the valve movement and prevent the valve from moving beyond its open or shut position I provide the valve member 22 with a pin 32 which extends down from the valve and into a position to cooperate with the edges of one of the ports 19 in port plate 16.

The placing of the springs in the manner shown prevents the heat of exhaust gases in the central body of the device annealing the springs and causing them to lose their strength; as they are spaced some distance from the body portion 10 they are cooled by air currents and retain their strength for a long period of time. It will be understood that I do not limit myself to the precise form shown in the drawings and described in the specification but what I claim as my invention is more particularly pointed out in the appended claims.

I claim:

1. In a device of the class described, in combination, a central body portion an inlet branch extending thereto, a tail pipe branch extending therefrom, a disk valve member having sector shaped ports, a port plate cooperating with the valve member and secured to the central body portion of the device, springs connected to lugs on the port plate and to rigid arms above the device and located without the body of the valve and spaced therefrom for maintaining the valve member in frictional engagement with the port plates.

2. In a device of the class described, in combination, a central body portion, an inlet branch extending thereto, a tail pipe branch extending therefrom, a port plate having a plurality of ports and secured to the central body portion, a rotatable ported valve member in cooperative relation with the ported plate, resilient means for press ing the valve member against the port plate and a deflector within the central body portion of the device for directing the gases toward the ports in the valve and ported plate.

3. In a device of the class described, in

combination, a central body portion inlet and exhaust branches extending therefrom, a port plate secured to the central body portion and provided with a plurality of ports for the egress of the exhaust gases, a valve member having ports adapted to be placed in or out of registration with the port plate by rotating the valve member, a deflecting baffle within the central body portion of the device for directing the gases toward the exhaust openings and resilient means located without and spaced from the body portion of the device and connected with the valve member for pressing the valve member against the port plate.

4. In a device of the class described, in combination, a central body portion of cylindrical form, branches extending into said body portion at the sides thereof and alined with one another, one of said branches be ing of smaller diameter than the opposite branch, a deflector within the body portion in front of the smaller branch portion and a cut out valve at the bottom of the cylindrical body portion for permitting the egress of the exhaust gases.

5. In a device of the class described, a cutout valve comprising in combination a central body portion, means for admitting and discharging gases therefrom, a ported plate secured to the body portion and forming a seat for a valve member, a ported valve member in cooperative relation to the ported plate and within the body portion, a shaft secured to the valve member and having a bearing in the ported plate and central portion of the valve casing, said shaft extending through the body portion and carrying a kick pedal on the upper end thereof, a pair of springs fastened at their lower ends to the ported plate and spaced from the body portion of the device, an equalizer bar eonnecting said springs'at their upper ends and having a portion adapted to press the before mentioned shaft downwardly and maintain the valve member tightly against its seat on the ported plate whereby the valve member is frictionally held in any desired set position.

In testimony whereof I hereunto aflix my I sign ature.
