Latem Patent No. 109,639, 'dated November' 29, 1870.
-IMPRovEMi-:NT IN PUMPS.
The Schedule referred to in these Letters Patent and making parl: of the same.
I, CHARLES MARKLEY, of N ew York, in the county and State ot' New York, have invented certain Improvements in AirPump for Steam-Engines, of which the following is a specification.
The object of these improvements is to eoonornize power in the condensing-engine, which, in connection with .the condenser, necessarily requires an air-pump to convey the water to the hot well after leaving the condenser.
Air-pumps'ibr such purposes are constructed with foot and delivery-valves. 1n general the latter is fixed tothe month ot' the pump-cylinder, the seat consisting ot' a grating,vthrongh `the openings ot' which the water must be forced, so that where the pump works quickly and draws a large amount of water the didionlty'resulting iii the effort to force it through the grating or through anyrlelivery-'opening of less. dimension than the cylinder greatly increases the labor of the engine, and, onaecount of the strain, is liable to break and otherwise damage the parts with which the piston-rod of the pump is connected. -Instance has :come to'applicants knowledge of the breakingof nine rock-shafts within the comparatively short period of three years, each shaft being six and a halt inches in diameter, wrought-iron, caused by the strain from the air-pump'. l
To obviate these difficulties is the purpose of applioants improvements. In the accompayning drawing representing van airpnlnp embodying applicants improvement-s- Figure 1 is a vert-ical section, and Figure 2is an elevation. A is the pump-cylinder, around the top ot' which is a reservoir, B, which should properly be of suficient capacity to contain the contents of the pump.
lhe cylinder A, it will be seen, extends somewhat above the lower part of' said reservoir, thereby preventing the return of the water.v It is also open at the upper end, so that no unnecessary exertion is required to discharge its contents. i
C represents a delivery-sluice, designed to -be of equal diameter with, or even greater than, the cylinder A.
D is agate-valve, hung at the inner mouth of the sluice and opening outwardly by the pressure of the water.
E is a cushioning-spring, to receive the. stroke of the valve at its descent.
This device consists ofthe -i- -shaped piece e, encircled by the spiral spring f, which rests on a snpporting-brace or arm, y, attached to a suitable brackeiaeh, the parts being severally constructed and arranged relatively" in'the manner clearly represented in the drawing.
The gate-valve is provided with a projecting flange, i, which, when the valve falls, strikes the upper end of the cushioning device, which extends through an opening in the delivery-sluice.
F represents the air-vessel, located above the delivery-slnicc and outside the delivery-valve. It is,
however, only necessary, as may be readily comprehended, in the event of va small delivery-slnice. Having fully described. my improvements,
iVhat I claim 'as new, and desire to secure by Let ters u' lrThe combination ofthe reservoir B, deliverysluice C, valve D, and cushion E, with the cylinder A, as and for the purpose set forth.
2. The arrangement of theair-vessel F, in combi'- nation with the siuice C, valve D, reservoir B, and cylinder A, as and for the purpose set forth.
CHARLESl MARKLEY.
