means for automatically controlling the supply of steam, utilizing the pressure on the water side of the pump to accomplish my purpose.
.The invention is an improvement on the pumps for which Patents have been 'grant` ed, No. 806,380, dated Deer-5th, 1905, and No. 809,590, dated Jan. 9th, 1906.
In the accompanying drawings z-Figure 1, is a side view illustrating my improved pump governor; Fig. 2, is a vertical secJ tional view; and Fig. 3, is,a sectional viewv illustrating a modication of the invention.
extends through a stuffing box c in the cap stem Bf is -a plungerD,'which extends linto a cylinder E supported on the cross bar C.`
A is the steam valve casing, havingseats a, a for the valve B, the stem B of which C of the casing A. Forming parts of this cap are standards c which support the cross bar C carrying'the governor mechanism.
Adjustably secured to the end of the'yalve This plunger is' reduced in. diameter and passes through a base e of the cylinder-gE' and has a flange d. Mounted between this liange and the screwl threaded stem of the plunger is a ring f in'the form of a cup leather turned upward, as shown.
In order tolockthe nut in its adjusted position, I provide a gam nut d2, Fig. '2.`
The reduced portion o the plunger is hollow, as shown, and mounted within the plunger is a rod F; the upper end of the rod being seated against the end of the opening in the plunger, and the lower end of the rod being mounted in the seat in a lever piv- -otally mounted Ona pivot-pin g, carried by a bracket c2 depending from the cross bar C. A bolt I-I is screwed into the crossV bar vand has a head L at its lower end and a lock f nut at its upper end.
Carried by the head h isa spring seat h2 and, mounted on this spring seat is a heavy sage 'communicating with a drip The pet cock-can be set to any point desired to allow the fluid in th.- cylinder above the coiled spring H', and resting on the upper endy of the coiled spring is another spring -seat h3, having projections h* forming rockers for the lever Cr. Adjustably mounted on the'crossbar is a set screw f by which the upward movement of the lever G is limited. The tension of t-he spring can be increased or diminished by turningV the rod II, and the position of the plunger D in respect to the -valve Bcan be regulated by turning lthe valve stem B in the threaded opening in the lower end of the plunger, and this stem may be locked in position by the jam nuts shown.
In the upper end: of the cylinder E is a passage communicating with a pet cock lv, and at the lower end of the cylinder is a paspipe 7c.
rin'gto escape, While the drip pipe carries away any leakage water which may pass the ring. and which would otherwise be entrap'pedsinth'e-lower portion of the cylinder.
Mounted above the cylinder E is a valve chest N; the lower half of the'- chest being formed, in the present instance, integral with the .cylinder,whi1e the upper portion N" is inXthe form of'a fianged bonnet ,and is secured to the lower portion by bolts,or
other? fastenings. Mounted vbetween the two sections of the fastenings is a diaphragm n, carrying a-valve n', having a leather seat disk n2 which rests upon the nipple m. This nipple issci'ewed into the head of the cylinderE and has'an opening therein, which -forms a communication between the interior ofthe valve casing N and the cylinder.
Communicating with the water' space unl der the diaphragm is a pipe L, which also lcommunicates with the water space of the pump, so that when the pressure of water `increases, it will lift the valve fn. oli` its seat and will allow the water to pass from the :valve casing N ythrough the passage in the nipple m int-o the upper end of the cylinder E, forcing the plunger down against the i' pressure oi the spring H', and at thensame time it will move the. valve B to close vagainst its seat, cutting olf the supply of steam to the pump through the valve A.
The valve n is kept toits seat, under normal conditions, by'a spring P, and the tension of this spring can be adjusted by a setscrew p, 'which extends through a has an inlet passage L from the water side ofthe pump; a passage k2 ,toh which the pet to the cylinder E. The diaphragm 7|, and
water on the water side of the moved upward at any speed desired, ac-

,' In Fig. 3, I have shown a modification of is as follows When pressure on the ,water threaded opening in\the bonnet and rests upon a spring Aseat p carried by the spring P. There is a lock nut on the adjusting screw p, so as to lock itin the position to which it is adjusted. Theuppr end of. the set screw is inclosed by al cap n2 screwed onto the bonnet N. f I
I] preferably provide a screen s, which is conical in shape, and extends from the outer edge of the diaphragm n'tol the base of the nipple m; thus straining the water which passes from the pipe L into the .valve casing so as `to prevent clogging of the small opening in the nipple and the other parts of the apparatus.
my invention in which the-"valve casing 91,3
cock is connected, and a passage e Yleading its spring p are similar in construction to theI mechanism illustrated` in Fig. 2. The nipple m is of greater length than that shown in Fig. 2, and does not ,extend into the cylinder E, but only to the partition of the valve casing.
It will be seen by the above construction that I provide governing mechanism -for a pump in which the pressure of steam is regulated automaticallyby the pressure of the pump. The plunger, which controls the' valve, can be cording to the position of the pet cock lo, which allows a given quantity of water to-` escape, while the plungeris moving to itsv full open position.` The plunger immediately closes the valve B as soon as the valve n leaves its seat. f
The operation of my improved gove'rnoi` sidey increases then it forces the valve it oli the cylinder, and forces the steam valve to the closed position against the-'pressure of its spring and, as scones; the pressure 4on ,the water side decreases, then the valve n will close against its seat on the nipple, prei venting theftlow'of water into the cylinderY and, as the' water above the plunger is al.
plunger will be raised, carryingithe steam valve off its seat n proportion to the amount ofsopening of the pet cock. Thus by'regulatf of a steam valve casing,
"'the- 'pres ing the pet cock the rapidity of the opening of the steam valve can be regulated. 1
the' flow of water through said leakage port,`
a drip' pipe communicating with the lower end of the cylinder, a ring` on the plunger located between the drip passage andthe leakage port, a hydraulic valve casing, a diaphragm withinK the casing, a valve car- 1 ried thereby, a spring pressing against the valve, a nipple within the valve casing and having a passagepommunicating with one end of the' cyli-nder, said valve closing against the nipple, with a pipe communicating -with theva'lve casing and leading from the water end ofthe pump;
2. The combination in a pump governor, a valve therein, a rod connected to the valve, a cylinder mounted above thevtsteam valve, aplunger ,therein having 'a ring tting. the cylinder, a lever bearing upon the plunger, a spring tending to raise the lever andy the plunger so as to move the steam valve to the open position, said cylinder having a leakage port at its upper end, a; valve controlling the iow'of water from said leakage port, a dripn pipe at the lower end of the cylinder, a hydraulic valve mounted above the cylinder, having a diaphragm, a hydraulic valve casing, a valve carried by the diaphragm,'a`
nipple against which the valve seats, said .nipple having` 'an opening communicating with the upper end of the cylinder, a springl tending to force the hydraulic valve to its seat, means for adjusting the tension ,of said spring, with a pip'e leading from the water side of the pump to7 the space between the diaphra `m andl the cylinder, so that, when iure of the water is increased, the
valve will bev raised and*y water will iow 'from Cthe hydraulic valve casmg into the cylinder, "causing the plunger to move the valve to a closed position.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses. l
