STEAM-PUMP.

SPECIFICATION forming part of Letters Patent No. 630,812, dated August 8, 1899.

Application tiled March 5, 1898. Serial No. 672,624. (No model.)

T0 all whom, t may concern.' A

Be it known that I, PETER LUDWIG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new Steam-Pump in Conjunction with a new Valve-Gear and other new Featnres,of which the following is aspect cation.

My invention relates to improvements in duplex steam-pumps in which both sides of the pump may be operated in connection with each other by the intermediate valve-gear, or either of the two sides may be cut out entirely and only one side operated, or each side may be worked independent of the other under different piston speeds,pumping different liquids. By the arrangement made in the eX- haust connection the pump may be Worked as condensing without using an additional vacuum or circulating pump. I attain such objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a side elevation of the pump. Fig. 2 is a front elevation of the pump; Figs. 3 and 4, a front and side view of the pistonrod clamp with guide-block; Figs. 5 and 6, a front and side View of the end pieces for the connecting-rods; Figs. 7 andS, a' plan and sectional View of the pump-piston;v Fig. 9, a front View of the stuiiing-box Withhandles; Fig. 10, a side elevation of the gland with screwed end; Fig. 11, a cross-section of a gland with iian ged end Fig. 12, a plan view of same 3 Fig. 13, a` detailed view of the wrist-bar; Fig.

14, a cross-section of the pump; Fig. 15, a

longitudinal sectional elevation of the pump along the axis of the piston-chambers.

Similar letters of reference indicate like parts in the several views.

The steam-cylinder casing a, the exhaust chamber b, the latter serving as a standard or leg, the pump-cylinder casing c, with the air-chambers d and e, and the suction-chamber f constitute, in conjunction with the center pieces g and h, the framework of the pump. The pump in its general features is the same as any other pump, but diifers from the pumps now in use in so far as two different liquids may be pumped at the same time under different piston speeds and either one or both sides may be worked condensing without the attachment of a vacuum or circulating pump.

The steam-cylinders are provided with the Corliss type of valves; but instead of having the connecting-rods of the valve-cranks connected to a wrist-plate they are connected to the rocking bars c' and t on both sides of the cylindercasing- Said rocking bars il and 7a are connected to the bent levers m and n bythe rods o and p. The bent levers m and n are fastened to the rocking shafts q and r. To the latter the rocker-arms s and t are also fastened. The rocker-arms s andconsist of a center piece and two side pieces or slides, the latter being adjustable in order to take up the wear of the blocks u and a. A detailed view of one of these guide-blocks, with the clamps 'o and the bolts w, is shown in Figs. 3 and 4:. These clamps o and w are fastened to the piston-rods a; and y.

The reciprocating motion of the piston-rods a: and fy is transformed to a rocking motion of the rocker-arms s. and t, as can be readily seen. From there the motion is transmitted to the valves by the bent levers m and n, the rods o and p, and the rocking barst` and la.

The connecting-rods o and p are provided on their ends with pieces a', a', b', and c', the latter having a slot to hook them to the corresponding bolts. This arrangement is made for the purpose of allowing the pump to be changed rapidly from duplex to single, or vice versa.

The standard n d serves as bearing for the rockenshafts q and r and is fastened to the center pieces g and h.

The above is a general description of the pump Working duplex. In orderto work each side of the pump independent from the other, the rods o and p have to be unhooked from the bent levers m and n and the upper ends of the rocking bars t' and 7c and hooked into the bolts of the guide-blocks u and u and the bolts in the lower end of the rocking bars i and 7c. This connection is indicated by the dotted lines in Figs. 1 and 2. After the valvegear has undergone the above alteration in the connections either side, or both, may be used as single pumps, and, if desirable, two different liquids may be lifted and discharged at the same time and at different piston speed. The steam for the cylinders is supplied by the pipes e andf. The exhaust is carried away to the atmosphere by the pipes g and h', or

IOO

where circumstances allow it the exhauststeam may beled into the suction-chamberf -by the pipes il and 71,', so that the steam compipe sections z" and la are made separate and detachable from the body of the pump, and tothis end the respective valves l', m', n', and o are arranged in the body portion of the pump-in manner indicated in Fig. l5, so as to control communication with such exhaustpipe sections, so that when said valves are closed the said pipe-'sections can be detached without affecting in the least the action of the pump-in a non-condensing manner, as heretofore described. The inlet for the suction is through the opening p and q in the two sides and r and s in front of the suctionchamber. t' and fu are hand-holes in the suction-chamber f for the purpose of getting access to the inside of said chamber in order to remove the sand, &c. which mayaccumulate, so that the base f serves also the purposes of "Ma mud-catcher.

The discharge from the pump-cylinder is through the openings w and fr on both sides of the pump-cylinder casing.

The steam-cylinder casing a, the pumpcylinder casing c, and the air-chamber j", with the exhaust-chamber b, are provided in the middle with partitions, so that each side is entirely independent from the other.

The piston for the pump, as shown in Figs. 7 and 8, consists of the piston-head y', secu red Iirmly to the piston-rod, the follower-head 2', loosely tted to the rod, and the elastic packing a2. Said parts y', z', and a2 are held together by four bolts. By tightening these four bolts the elastic packing will be pressed together, and consequently increase its'diameter. In order to set the elastic packing, it is necessary to remove the cylinder-head only.

The gland, as shown in Figs. 9, l0, l1, and l2 in different views, is used all over the pump wherever a gland is necessary, and the same may be applied on any similar piece of machinery wherever needed. The stulng-box proper, b2, screws into the casing c2 instead of screwing over the outside of same. The metallic ring f2 will prevent the stung-box from cutting into the packing when the latter is screwed in. Said stuffing-box Z22 is provided with handles cl2, as vshown in Figs. 9 and l0, and obviates the use of a wrench. The casing c2 may be made with screwed end, Fig. l0, or with anged end, as shown in Figs. ll and 12.

Ifam aware that prior to my invention duplex pumps have been constructed so that one side only could be set working. I am also aware that prior to my inventionsteam-pumps have had their exhaust-steam passage of the steam-cylinder connected to the outlet-passage of the water-cylinder. I therefore make no claim broadly to such feature of construction; but,

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
