IMPROVEMENT IN CONDENSING PUMPINGfENGlNES.
Specification forming part of Letters Patent o. 184,339, dated November 14, 1876; application led January 17, 1876.
To all whom it may concern: h
Be it known that We, ADAM GARR, of Paterson, in the county of Passaic, and JAMES ARTHUR, of Jersey City, in the county of Hudson, both in the State of New Jersey, have invented an Im provement in Condensing PumpingEngines, of which the following isa specilication Surface -condensers in which the steam passes through ranges of tubes in a waterspace are well known, and condensing pumping-engines have also been made .use of. 1n many instances, such as the water-works of cities, pumping-engines are employed, some of which are low-pressure condensing-en gi nes.
Our present invention relates to the combination,'with a puml'iing-engine, of a surfacecondenser, placed in the waterway above the lWater-pump, an air-pump for removing the Water of condensation, and a direct connection to the steam piston-rod, whereby the engine 1srendered very compact, and the water passing through the pump in the ordinary manner is rendered operative 'in the condenser. t
We provide a self-acting relief-valve that opens it' the pressure from any cause becomes in excess ot' the atmosphere, and we arrange this valve in such a manner that it may be moved to allow the steam'to discharge directly into the atmosphere.
In the drawing, Figure l is an elevation of the pumping-engine, with the exhaust-valve and chest in section; and Fig. 2 is a sectional plan of such condenser and Valve-chest.
The steam-cylinder a and-pumping-engne b are of any desired character, and we have shown these as direct-acting. A
The condenser is made of the tubes d, passing through the heads e, and these are placed Within the water-way ot' the pump, so that the Water, in passing` to or from the pump, circulates around these `tubes d and between the said heads e, the passage-waysf, for steam and water of condensation, being at the outsides of these heads e. We haveshown this condenser as placed above the pump, in order 4that the water of condensation, may run by the pipe g to the airapump h, that is operated by an arm, k, from the cross-head k of the steam-pump, and the feed-water plunger Z is also connected to this same cross-head. yThe pipe m conveys the exhaust steam from the engine to the condenser, and by placing a valve-chest, n, at the side of the steam-chest o, and allowing the steam to pass through the ports 2 and 3 in reaching this pipe m, we are enabled to use a valve, r, over these portsv 2 and 3. This valve T is in a frame, s, by means y sufficient to maintain a vacuum, thereby preventin g undue back pressure upon the engine, and a weight, t, may be employed to keep the valve to its seat with any desired force.
We are aware that a condenser has been combined with two pumps, 'and that water has been supplied to the condenser by one pump and removed by the other, and that such condenser has been partially a surfacecondenser. rlhis construction is complicated and expensive, and the two pumps and the condenser have to be constructed with reference to joint action. In our improvement the pumpingengine is not changed in its character or action, but the water that is pumped goes through the surface-condenser without entering the steam-space thereof, and
without any opening between the water-space and steam-space; hence the condenser cannot become filled with condensing-water,l nor the vacuum of the condenser affected either one way or the other by the waterpomp.
We claim as our invention- 1. Thecombination, with a pumping-engine, 'of a surface-condenser, placed in the waterway above the water-pump, .an air-pump adjacent to the water-pump, and a connection to the steam piston-rod, substantially as specied.
2. The combination, with apumping-engine and surface-condenser, of a valve placed in the exhaust passage-way, and arranged to lift automatically by surplus pressure, or to be moved to allow the steam to escape to the atmosphere, as set forth.
Signed by us this 15th day of January, A.
