H. DAVEY. PUMPING ENGINE.

HENRY DAVEY, OF \VES'IMINS'IER, ENGLAND.
PUMPING-ENGINE SPECIFICATION forming part of Letters Patent No. 391,457, dated October 23, 1888.
Application filed September J4, 1887. Serial No. 250.045. (N0 model.) Patented in England Febmary24, 1887, No. 2,859.
To all whom it may concern:
Be itknown that I, HENRY DAVEY, a subject of the Queenof Great Britain, formerly residing at I-Ieadlingley, Leeds, in the county of York, England, and now at No. 3 Princes Street, in the city of Westminster, in England,
ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. v
My invention relates to steam pumping-engines; and it consists of a novel construction, combination, and arrangement of the parts,
whereby the steam-pistons can be directly connected to the pump-pistons and the pumps operated by means of steam of varying pressure or expansive] y.
In the accompanying drawings, Figure 1 is a top view of a double-cylinder steam'engine and a double-cylinder ,puinp provided with my invention. Fig, 2 is an end view of the same; and Fig.3 .isa top'view of a part of the apparatus, showing my invention slightly modified in the arrangement of the parts,"
whereby direct connection of the pistons with bucketpumps can be efi'ected.
The letter A in the drawings represents a steam-engine of ordinary construction; B B,
two num )-c linders and a a are piston-rodsb b, connecting-rods, and O a bell-crank lever.
The pistons of the steam engine and pumps (illustrated by dotted lines in'Figs. 1 and 2) are fastened to piston-rods a a, as usual, and the valvegearing, which is not shown in the drawings, is also of ordinary construction, and needs no description. The piston-rods a a are provided with cross-heads a", and these crossheads are by means of the connecting-rods b b connected with the arms 0 c of the bell-crank lever O, which has a fixed fulcrum at c The arms a c are set at about a right angle,whereby the motion of the connecting-rods b b is varied relatively and mutually, inasmuch as the foreing-stroke is made with an increasing effect on oneside of the machine, while the simultaneous suction-stroke on the other side is effected with a gradually-decreasing force. ,,This is owing to the varying leverage produced by the varying positions of the bell-crank lever O.
The steam-piston attached to the plunger l reversed, as seen in Fig. 3, because the resistanee on the lifting-buckets is opposite in direction to that of the'forcing'pluuger, and-the increase and decrease of the operating force must also be reversed by reversing the varying mechanism of the engine, as illustrated.
The invention herein described renders steam pumping-engines very compact and less costly; also makes them positive and effective in their operation of working pumps with steam of varying pressure or expansive) y.
What I claim is Reciprocating steam-pistons and pump-pistons directly connected to one another by rods a a, in combination with rods b b, and a speedgrad uating bell-crank lever, G, substantially as and forthe purpose described.
In testimony whereof I affix my signature in presence of two witnesses.
HENRY DAVEY.
