f eUsTAv BERNHARD PETs'cHE, OE PHILADELPHIA, PENNSYLVANIA,
AssIGNOR rro THE sOUrH-wARx `EOUNDRY a MAOHINE OOMPANY, OE PHILADELPHIA, PENNSYLVANIA, A `CORPORATION vOE 4PENN- SYLVANIA.
THROTTLE-VALVEA Patented Oct.` 23, 1906.
Application led October 20, 1905. Serial No. 283,581.
l PETscHE, a subject of the German Emperor,
residing in the city and county of vPhiladelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Throttle-Valves, of which the following is a true and exact description, reference' being had to the accompanying drawings, which form a part thereof.
My invention relates to throttle valves such as are used in connection with the supply-mains of steam-engines, and has for its object to provide throttle valve mechanism `adapted for frequent use-as, for instance, in
connection with a reversing-engine-and in which the valve can be closed and opened powerfully and positively and automatically held in closed position.
The nature of my improvements will be best understood as described in connection with the drawings, in which they are illustrated, and in whichy Figure 1 is a plan view of the valve and actuating mechanism; Fig. 2, a vertical section on the line 2 2 of Fig. 1, and Fig, 3 a perspective view of the togglejoint-actuating mechanism.
A indicates the valve-casing, having the chambers A and A2 connected with each other through a cylindrical valve-guide B, which is placed in alinement with a valvev seat,(indicated at 0,) ysaid seatbeingformed on the edge of a disk head C', lying beyond the end of the cylinder.
D is the throttle-valve, consistingy of a hollow cylindermoving inthe cylindrical guideway B and adapted to contact with the seat C, as shown in Fig. 2. 4
D indicates the valve-actuating spindle, which, as usual, passes through a stuiiingbox in the cap E of the casing, said cap being provided with upwardly extending standards E E, to which are secured theguideway indicated at F, and above it the pivot indicated at G.
H H represent a bell-crank lever pivoted at G, its shorter arm H being bifurcated and provided with a pivot-pin I.
J is a head secured to the valve-spindle and 5o working in the guideway F. This head supports the pivot pin indicated at J and through upwardly-extending arms J2 J2 a lock-pin, (indicated at J3.)
K is a link pivotally connecting the pivotpins I and J and, as shown, formed with a radial slot K, through which'- extends the pin J 3.
It will be seen that the lever-arm H and link K form a toggle-joint arranged in such a way that when its members are in alinement the valve D will be pressed down against the valve-seatC, while the shifting of the leverarm H will cause the links of the toggle-joint to move out of alinement and open the valve. It will also be seen that the pin J 2 by coming incontact With the end of the slot K forms a stop and lock Jfor arresting and holding the toggle -levers in alinement and the valve closed.
Obviously other locking devices may be provided in place of the one illustrated, and except so far asv the specific mechanism is called for in the claims I do not wish to be understood as limiting myself to the details illustrated.
My throttle-valve mechanism in somewhat ymodilied form is also illustrated and described in my copending application for Letters Patent, iiled October 20, 1905, Serial No.. 283,580. i
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. A throttle-valve having in combination a casing provided with a valve-guide cylinder B, a disk head C lying beyond the endl of said cylinder and having a valve-seat C situated in line with said cylinder, a hollow cylindrical valve D, working in the guide B, a toggle-joint valve-actuating device arranged to seat the valve when its jointed links are in alinement and a lock-stop for holding the links in alinement and the valve closed.
2. A throttle-valve having in combination a casing provided with a valve-guide cylinder B and valve-seat C, situated in line with said cylinder, standards E', E', secured to the casing, a guideway F', and pivot'G, supported on the ltandards, a hollow oylindril valve1 D,
