IMPROVEMENT IN VALVE-MOTIONS FOR STEAM-ENGINES.
Specification forming part of Letters Patent No. 197,951, dated December 11, 1877; application filed October 27, 1877.
To all whom it may concern:
Be it known that I, HENRY TAYLOR, of Baltimore city and State of Maryland, have invented a new and useful Improvement in Valve- Motions for Steam-Engines or Donkey Steam or Air Pumps, which improvement is fully set forth in the following specification, reference I being had to the accompanying drawings.
The object of my invention is to alternately open and close the valves common to steamengines ordonkey steam-pumps by means of mechanism fully explained in the following specification and claim.
vFigure 1 is a side elevation. Fig. 2 is a plan.
Like letters represent like parts in each.
A rep resents the piston-rod that connects the pistons of the donkey engine and pump together. B is the valve-rod common to steamengines and donkey-pumps. It is connected with the steam-valve P at S, and worked, as usual, through a stuffing-box.
O is an adjustable arm, common to donkeypumps, fastened on A by means of the setscrew D. The upper end of the arm plays freely over the valve-rod B.
E and F are two adjustable rectangular latch-blocks, fastened on B with set-screwson opposite sides of the arm 0. They are capable of being changed by reversing their ends or revolving them on B, so that when one latching-point wears, five others may be used before the blocks are Worn out. The functions of these latch-blocks are to hold, in connec tion with the hooks'K and L, the valve at any desired point on opposite sides of the steamports.
G and H are bell-crank rock-shafts, suspended on pivot-b0lts in .the frame of the engine, on opposite sides of the arm 0. M and ton is atthe end of its stroke, as shown at L.
R represents the frame between the steamengine and pump.
The operation of my invention is as follows:
When the piston-rod A moves in the direction of the arrow T the arm 0 continues to compress the spring N- against the block F until the piston is nearly at the end of its stroke, when the arm 0 strikes the pendent lever J of the'rock-shaft, and raises the hook L above the block F, when the force of the spring reverses the valve, and the piston moves in the opposite direction, performing. a like action, thus securing a constant and reliab e motion to the engine and pump., This method of operating valves may also be used as a cut-ofl' to use steam expansively, for which I contemplate applying for a separate patent.
Having described the construction'and operation of my invention, I claimr The arrangement of the piston-rod A, valverod B, arm 0, latch-blocks E and F, rockarms G and H, springs M and N, spring 0, i and valve P,said parts being constructed and operating substantially as herein shown and described,,and for the purpose set forth.
