WATER-MOTOR.
SPECIFICATION forming part of Letters Patent No. 396,729, dated January 29, 1889.
Application filed November 11, 1887. gerial No. 254,907. (No model.)
To all whom it may concern:
Be it known that 1, JOHN COATES, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Tillproveinents in \Vater-Motors; and I do hereby declare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.
This invention relates to water-motors; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.
My device is illustrated in the accompanying drawings, as follows:
Figure 1 is an elevation perspective view of the cylinder, valve-chamber, and valve-gear. Fig. 2 is a 'erticallongitudinal section on. the line 11; n in Fig". '3, looking in the direction of the arrow on said line. Fig. is a horizontal central section in the line .1;- :1: in Fig. 2. Fig. lis a vertical section on the line 1 y in Figs. 1. and S, Fig. 5 is a vm-tical section on the line I: z in Figs. l and fl, showing only a fragment oil the parts out by that line.

E is a secondary-valve chamber back of the main-valve ehaniberand atright angles thereto E E, the secomlary valve; F, the supplyport of saidsecondary-val ve chamber; ff and f the ports of said chamber; (it, the exhaust- 1.)assage:t'rom. said secoinlary-valve chamber to the exhaust-passage (l B is the main piston; l), the n1ain-piston stein; I), a tappct-arm on said pisttm-steni.
E is the stem of the sectmdaryvalve E; Z) and e c, tappets on said stem E H, a tappet-lever pivoted on an arm at It and connectin gr with the stem (Z of the main valve.
The construction and operation of my motor are as follows:
The cylinder is of ordinary c(n1struction. The passage-chambers A A extend from the opposite ends of the cylinder on opposite sides thereof and meet in circular chambers at the central part of the cylinder, at which point is located the breast A to which the valvechamber is attached. The main valve D stands at right angles to the cylinder. The valve is actuated by the water-pressure, and also by a valve-gear, and as the cylinder A is intended to stand perpendicularly the valve will lie horizontally, which is desirable, as then its weight will not moveit when the motor is at rest. ing two heads, in which are D-passages d on one side, as seen in Fig. 1,). The valvechamber D is provided with entry-ports (Z d at the ends, which. connect with the secondaryvalve chamber E, and the supply-port oi the secondary-valve chamber is in the opposite.
wall of the main-valve chamber from the main supply-port S, and is marked F in the drawings. The secondary-valve chamber is set at right angles to the main valve and parallel with the main cylinder. This enables me to move the secondary valve by direct action from the main-piston stem B by a tappetarm and tappets. Only one of these tappets, Z), is shown, the other being on the rod E above. On the stem of the secondary valve are placed two other tappets, e e, which operate the lever II, which. is pivoted at h on a fixed arm and has its free end inserted in a slot in the stem (Z of the main valve.
The operationv of these valves and gears is as follows: \Vhen the piston 13 is finishing its stroke, one of the tappets l) on the valve-rod E struck and moved by the tappet-arm b 011 the piston-stem B. This action moves the secondary valve E, and this admits water to the opposite end oi? the valve-chamber D through one of the ports and it also opens the same port at the opposite end to exhaust, thus changing the pressure of fluid from one end of the val ve D to the other. In case the valve l) did not stick, this change of pressure would move that valve to the opposite end of the \'2Ll\'0(jll&'l1lllei; but it cannot be dcpended upon not to stick. All fluid-actuated valves in water-motors will occasioi'ially stick, and when the motor is used for direct action, as in blowing; an. organ-bellows, and having no balancc-wheel, it is neeessaryto use a fluidactuated valve, because there is no elasticity This valve is piston forn1,l1avin the fluid used and no accumulated momentum to carry the valve over the ports. To prevent the valve sticking, I apply a mechanical valve-gear in the form of the lever H and the tappets e c, (or in some other equally-desirable form.) I rig this mechanical gear so that after the secondary valve 11 is commenced its movements the lever H, or such other gear as may be used, is moved, and the valve D is given a mechanical impetus which will set it in motion, and then the fluid-pressure will complete its movements, As before stated, a mechanical gear cannot be used alone when there is no accumulated momentum, as in a balance-wheel, as it would only move the valve over the ports and then stop, and a pressure-actuated valve is uncertain, because there is often not enough force to start the valve. I therefore combine with a pressureactuated valve a mechanical gear to give the valve an initial impetus, and thus insure against sticking, and then leave the pressure of the fluid to carrythe valve over the ports.
' hat I claim as new is- '1. In a water-motor, the combination of a main cylinder, A, having passage-chambers A A extending from its ends to its middle point, and then connecting with a breast and an exhaust-passage, a secondary-valve chamber formed within said breast, which is parallel with the cylinder-chamber, and a steamchest having a main-valve chamber at right angles to said cylimler-chamber fixed on said breast, thereby placing the secondary-valve chamber between the main-valve chamber and the cylinder and at right angles to said main-valve chamber.
In avwater-motor, the combination of a main cylinder, A, having passage-chambers A A extending from its ends to its middle point, a circumferential exhaust-passage, C, located at said middle point, a breast at said middle point, in which said passages terminate, a valve-chest fixed upon said breast, and having therein a main-valve chamber lying at right angles to the main cylinder and a ary valve from the main piston, and a mechanical valve-gear for giving the main valve an initial impetus in the direction of the fluldpressure admitted against it by said secondary valve.
3. In a water-motor, the combination of a main cylinder, A, having passage-chambers A extending from its end to its middle, a breast, A at its middle, an exhanstpassage extending from said breast around to an exhaust-nozzle back of said cylinder, a valvechest attached to said breast containing a main valve which lies at right angles to the cylinder, and a secondary valve which lies parallel with the cylinder, and between. it and the main valve, said secondary valve admitting fiuid under pressure to the main valve, and the main valve admitting fluid under pressure to the said cylinder, substantially as set forth.
i 4. I11 a water-motor, the combination of a main-piston chamber, a main-valve chamber at right angles to said piston-chamber, a secondary valve between the main-valve and the piston chamber, which is at right angles to the main valve, and a lever for communicating motion from said secondary-valve stem to the stem of said main valve.
In testimony whereof I aflix my signature in presence of two witnesses.
JOHN COATES.
