Description
MARTIN BRAUN, OF CAPE VINCENT, NEW YORK.
Letters Patent No. 105,035, datetl July 5, 1870.
IMPROVEMENT IN DOUBLE-ACTING PUMPS.
The Schedule referred to in these Letters Patent and making part of thesame,
To all whom it may concern:
Be it known that I, MARTIN BRAUN, of Cape Vincent, in the county of Jefferson and State of New York, have invented a new and improved Doubleaction Force-Pump; and I do hereby declare that the following is an exact and full description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.
My invention relates to force-pumps; and
Consists in the novel construction and arrangement of a valve having-another valve within it, in combination with a plunger operating in a barrel provided with valves at its upper and lower ends, all as hereinafter described.
In the drawings- Figure l is a longitudinal vertical section of the entire apparatus, and
Figure 2 is a longitudinal vertical section of a portion of the same enlarged.
The object of this invention is to produce a simple,
strong, and eflicient force-pump by means of the novel construction and arrangement of its valves.
A barrel, A, of any desired size and of any suiteble material, is provided at its lower end with a valve,
B, and at its upper with valves 0 and D, constructedand arranged as clearly shown in figs. 1 and 2.
Within the barrel A is placed a hollow plunger, D. This plunger is screwed into the cap a on thelower end of a hollow pumprod, E, with which it communicates.
Before the plunger 1) is tbusconnected there is arranged within it a slide or lift tubular valve, F, with an enlarged upper end, in which is placed a small lift-valve, c, with a stem, (Z, passing through a crossbar, I), on the upper end of the valve F, as shown in both figures. v
This tubular lift-valve F is provided with shoulders, 0, just below the enlargement on its upper end, which strike against corresponding shoulders, f, on the upper interior side of the lower end of the plunger, so as to limit the downward movement of the valve, and its lower end is provided with a flat ring, g, which screws upon it and limits the upward movement of the valve, all as clearly shown in both figures.
The plunger D is provided with ports, 72, on its sides, so arranged, in relation to the shape and length of movement of the valve F, that when this valve is down the ports will open into the plunger, and when up they will be closed.
It will alsobe seen. that,'when the ports open into the plunger, communication with the interior of theplnnger and the space below it is shut ofl, and that when the ports are-closed by the movement of the valve 1*, communication through the valve F between the interior of the plunger and the space below is opened.
The pump-rod is operated in any of the ordinary ways, and communicates with suitable flexible hose, as shown in fig.-1. I
The operation of a pump thus constructed will be readily seen from the drawings.
The barrel A, being surrounded by or communicating with a full supply of water, entering through the valves 0, D, and E, and filling up the space in the barrel, it only becomes necessary to put the plunger in motion. As it moves down, the valve B, at the bottom of the barrel A, is closed,-and the, valves C- and D at its top are opened, and the pressure of the water under the plunger at once carries the valve F up until its ring, g, strikes against the under side of the plunger, when the ports h are closed. At thesame time the small valve '0 is lifted and communication is opened with the interior of the plunger and on through the pump-rod with the hose. And as the plunger moves up, the valve B is opened, and the valves 0 and D are closed, in which case the gravity or weight of valves F and c, in connection with the pressure of the water above and the release of its pressure below, cause these valves to fall, thus opening the ports liand-closing communication with the space in the barrel A, below theplunger, and opening it with the space aboveit, when the water in this upper space will be forced through the ports h and on through the plunger and pump-rod to the hose, as before.
In this way, by the alternate movements of the plunger, a continuous stream will be thrown, similar to that in the ordinary double-acting force-pump.
Having thus described my invention,
. What i claim is In a force-pump, th combination of a hollow plunger, D; with a lift tubular valve, F, having a. liftsvalve,
c, therein, when constructed and arranged -to operate substantially as herein described.-
MARTIN BRAUN.
