SPECIFICATION formngpartof Letters Patent No. 650,075, dated May 22, 1900. Application nea nach 19, 1900. serial No. 9,311. cio-moan.)
In most reciprocating steam-engines the.
piston movement must be to the same distance with every stroke 5 but there are many pumps in which a shorter or a longer stroke may be made, with the only dilerence in result that less water is lifted by a short stroke than by along one. It thus becomes desirable to have a changeable stroke, so that the full power of the engine may be applied to the movement of the pump-piston a short distance should the resistance be great, or a full stroke of the pump-piston may be made when the .resistance is such as to permit the maximum quantity of water to be lifted by the pump.
Figure l of the drawings isa plan, and Fig. 2 a side elevation, of a steam-pump according to the principles of the present invention.
A indicates the steam-cylinder, to which steam is supplied in any suitable manner through steam-chest B, the valve therein being controlled by usual connections from the crank-shaft, as indicated at C. The pistonrod D of the steam-cylinder is connected to a cross-head E, which slides on guideways F F. A rock-shaft or spreader G extends through the cross-head E, and to the ends of this spreader G two pitman-bars I-I are connected. The pitman-bars H are connected near the other end of the steam-cylinder bya couplingbar I, which in turn is connected to the crank K of crank-shaft L, said crank-shaft being supported in usual bearings, as M. At each end of crank K a disk O is attached to said crank, and these disks are of course rotated as the pitman-bars reciprocate. It is not very material whether spreader G rocks in the cross-head E or Whether the spreader be fixed and the pitman-bars rock thereon.
The disks or fly-wheels O will be driven by the reciprocation of the piston-rod D through the mechanism described. VThe disks O vare slotted, and in the slots O wrist-pins P P may be adjusted at any distance from the center by means of nuts or usual fastening devices. To these crank-pins P pitman-rods Q Q are connected, both leading to a spreader R, which passes through a cross -head S, this cross-head being guided on the slideways F F. The cross-head S is connected to a pumprod T, so that the rotation of disks O reciprocates spreader R and cross-head S, and the length of this reciprocating movement is determined by the position of the wrist-pins P in the slots O'.
The pump-cylinder W is of usual construction, the valves operating to cut O and supply the liquid thereto in usual manner.
The valve-controlling mechanism C may be located in any convenient position, so that eccentrics on the shaft will control the move-- ment of the slide-valve.
From the above description it is thought the general principles of my invention will be well understood. The reciprocation of the steam-piston is uniform as to distance, and the connections from such piston serve to rotate the disks or fly-wheels O. These fiy-wheels,bein g at opposite ends of the crankshaft, give convenient means for attachment of the long pitman-bars Q Q and are in position to balance the crank, or very nearly so.
vThe adjustment of Wrist-pins P may be according to the desired stroke of the pump, and by setting the cross-head S to a desired position and loosening the fastenings of the Wrist-pins these pins will find their proper positions in slots O' and may be there secured in such manner asto cause any desired throw of the pump-piston within the limits of the capacity for adjustment determined by the length of slots O.
I do not limit my claims to the precise construction of parts, as it is understood that the substitution of equivalents does not change the nature of the invention.
l. In a steam-pump, the combination of a steam-cylinder, piston-rod, and cross-head, a pitman from said cross-head to a crank-shaft, and a slotted disk on said crank-shaft and a wrist-pin therein, and a pitman connected to IOO 2 f l l 650,075
