@wird gieten @aient-@Mira 'MARriNwILcoX or SACRAMENTO, CALIFORNIAA Letters Patent No. 100,576, dated Ma/rch 8, 1870; antedated December 30, 1869.
JIMPRovnMN'r n v STEAM-PUMP nnvrcns.
The Sched'ule referred to in these Letters E-atent and'making part of the same.
To all 'whom tonay concern: t Be it known that I, MARTIN WILeox, of the city and county 0f Sacramento, and State of California, t have invented a new and useful Steam-P ump, of which the following is atruev and full description, reference being had to the accompanying drawings and to the y letters of reference marked thereon.
This invention pertains to'exhausting and condensi; ing steam fsom` the cylinder'ofa steam-pump; to dis# posing of uncondensed steam or air after condensation; to working stearn""`xpansively after the cut-off;
and to working steam by condensation alone, or with- `nutpressnre, as in caseof taking the escape steam f from an engine.
The following isla description of, the different parts i l of the `pump-- and K.
I, discharge-pipe for water. J, passage opening into K and space above U, .Ksnpplypipe for water.V i y l Figure-2..
L, a steam-gate admitting steam to C.
M, a rod to work steam-gate L.
4 N, weight sliding on M. O O, float, with openings in center-for M.
W W, partitions across H, with openings at the ,bottom l Y X, the point at which to attach D, instead of to O,
. if desired.
T, a sliding' plate, to which SS areA firmly at- 1 tached. L
U, an opening through T, and the plate beneath i which closes, or is cut od by right movement of' T.
rlhe operation of the pump is as follows: l First, suppose all parts but A are filled with water, the float will raise the gate L, and 1ct steam into C.
t R being closed, the pressure of water opens S S, and, closing U by slide '.l, water escapes through I'until l the iioat O O settles, and with it the weight N until f N strikes the button or stopon lower end of gate-rod M, and cuts o' steam. l
Vcontinue the ow afterst-eam is cut oil'.
The4 back draught of water, assisted by a spring, if needed, closes S S, and opening U allows the weight of water in supply-pipe to makea draught through U upon the parts above U. This draws water outof and steam into E, and also brings a jet of water. through F to` condense steam in E.
t When condensation has produced suir'icient vacnum to raise water through supply-pipe K, .the valve Q prevents water-rising in' E. Y
`When .receiver is again filled, the float, raisingV the weight against the upper button on the rod lifts'L';
and lets on steam again, and the discharge repeats. 'At the end of the next stroke, the draught through U brings the uncondensed steam before lodged in E down through Q, whence it escapes into chamber under Rand out at next stroke.
To work steam without pressure, the discharge should not be abovel the point at which the top of the' iioat stands at the end ofthe stroke, as the discharge t is effected only by the weight of water in. receiver above the level of the discharge. The whole eleva; tion in this case is effected by condensation.
-To work steam expansivcly, set the button on the lower end of M so high that the weight N will strike it while the float is 'yet some distance above the passage leading into H, as the float acts as a valve to that opening when it reaches it. Let the discharge- `pipe beol great length compared with its elevation and the, momentum of current in discharge-pipe will The exp'ansion of steam and momentum of current then finish the stroke.
This arrangement provides against a waste of power in case of running a pump for a low lift, in connection -with other machinery which requires high pressure of `steam-muchl higher than would be required for the v pump.
Claims.
I claim as follows: 1. The arrangement of the supply-pipe of a steampump whereby to produce a draught .on its exhaust steam by means of an opening or draught-passageA between the two, substantially as set forth.
2. The pipe D and condenser E, .in combination wit-'h the receiver C and discharge` I, constructed iu the manner and operating substantially as represented. 3. The Weight N, in combination with rod M, gate L,fand float O G, constructed and operating in ,the manner and for the purposes as explained.
MARTIN l WILGOX.
