Description

valve J.
through 'passages N N'. The cylinder I is a1 'section df the pumfp-vawemrd the piston O independent of the valve G. This motion is provided for the purpose of admit ting live steam direct from the chest to the cylinder l through one or the other of thc hollow rods P 1 and perforations ay a. It will be seen by reference to Figs. 3 and 4 that the ports t' and 6 communicate with the cyl'- inder I at points a short distance from the re spective ends of the cylinder, for the purpose ot' causing the piston 0 to run over these ports and cushion on the steam thus in closed.
Operation: When the piston in the cylinder A has moved in the direction of the pump B sufficiently far in terminating its stroke in that direction as to force the valve J into the position shown in Fig. l, by the means before eX- plained, steam is then exhausted from the end of the cylinder I, on which rod P is situated, into the port D, and the excess of pressure on the opposite end starts the piston in the direction ci' port D suiiciently to close the hollow' end of rod P against tace g', and open the hollow end of rod P, so as to admit live steam, which serves tocontinue the motion of the piston, and consequently valve G, until the flts,su"1ciently loose to permit the valve to move its full stroke independently. This lever is secured to rod Q, which projects through the chest H, and is packed by the hub s ot' the lever S, which slides on a feather on the rod Q, and is tightened by nut s. The lever S is designed to be operated by hand.
The watercylinder is constructed with four valve-chambers, 1, 2, 3, and 4, which are all exposed by the removal of the cap T, which, as shown, embodies the air-vessel T. The cap is secured to the cylinder B by four or more bolts.
The chambers 1 and 2 communicate with the suction-pipe U below the valve-seats, through passage V, which nearly surrounds the pumpbarrel, and with the pump-barrel through passages 5 and 6 above its valve-seats, and with chambers 3 and 4 by passages 7 and 8 above the valve-seats, so that these chambers receive water freely below the valve-seats from the suction, also discharge water into the pumpcylinder and communicate water to the cham. bers 3 and 4 from the pump-cylinder. The chambers 3 and 4 merely receive water from the chambers l and 2, and the same is discharged through the valves into the passage W, formed in the cap T, and from thence into the pipe X.
The seats 9.and 10 of the suction-valves 11 and 12 are driven snugly into the counterbores made to receive them, and are kept down by the skeleton rings V`Y,.against which the cap Trests. l
The seats 13 and 14 ofthe discharge-valves 15 and 16 are driven into the counterbores shown in the drawing, and are held in place by the cap T, the holes Z, through which the valves work, being smaller than the diameter of the seats. v
The valves 15 and 16 are limited in their ascent by the shell of the spherical cavities in the cap T, and the suction-valves rise against the `joint face of the cap T. All the valves may be returned to their seats by spiral springs,
if necessary.
The valves and seats are constructed 1n a peculiar manner, which is shown 1n Fig. 8.
The seat b has a central guide-stem, c, casty` in connection with it, which has a hole, d, formed through it. The valve b hasa hollow socket, e, closed at the upper end, in to which the guide-stem c slides snugly.
The perforation d gives a vent for the water which collects in the hollow socket e. than one valve and scat can, of course, be placed in each of the chambers 1, 2, 3, and 4, in large pumps, if desirable.L
The piston of the water-cylinder B is ccmposed of the peculiarly-shaped heads fj" with the addition, when `leather is used, of the` i l l l washer f.
The head f is formed with a hollow cylindrical extension, fl", and the head jl is counterbored, as shown in position in Fig. 7, to receive it. By the simple reversal of the heads, the piston is made to receive packing, as in Fig. 7, or cupped leathers, as in Fig. 6.
An important part of our invention, not specified in the preample of this specification, is in the provision of the set-screw h, which is fitted to screw, when necessary, against the solid part of the piston of cylinder A, and firmly hold this piston,'its rod, and thepumppiston, and thus enable the pump-pistou to be packed without danger of slipping or twisting of the pistons in the cylinders. After packing, the screw h is released from contact with the piston by unscrewing slightly.
We claim- 1. In connection with the valve G g g and valve J, the latter operating by suitable connection with the engine, the supplemental cylinder I, ports i t" i 11', passages M N N', and piston O P P c c', combined and operating substantially in the manner and for the purpose speciiied.
l2. The manner of packing the shaft Q by the hub s of the hand-levers S, as and for the purpose described.
3. The seat b, having aperforated central guide-stem, c d, cast in connection with it, in the described combination, with the valve More ' y for the purpose specified.
b, constructedwith a hollow socket, c, as and 4. The water-cylinder B and ca-p T, when constructed with chambers 1 2 3 4, which are all exposed by the removal of the cap, and Whenconnected with the suction-pipe, pumpcylinder, and discharge-pipe, substantially in the manner described.`
5. The piston f f j, constructed substantially in the manner and` for the purpose spec.
