IMPROVEMENT IN PNEUMATIC PUMPS.
Specification formingpart of Letters Patent No. 174,086, dated February 1876; application filed l July 17, 1875.
To all whom it may concern Be it known that I, THOMAS-O. PERRY, ofl
Tecumseh, in the county of Lenawee and State of Michigan, have invented certain Improvements in Pneumatic'Pumps, of which the following is a specification:
My invention relates to a device for raising water by means ot' compressed air; and consists, rst, of an air-valve to allow the alternate admission and escape of air to and from a submerged water chamber, for the purpose of driving the wat-er out and lettin g the chamber refill; second, of a device for rendering the operation of said valve automatic by means of a float in the water-chamber.
rEhe air-valve may be connected with either one or two water-chambers.
[n the drawing, Figure 1 is a vertical section of the pump, cutting the air-valve through g h', Fig. 3, and showing the iioat and interior of the waterchambers. Fig. 2 shows the exterior of the air-valve revolved half around from the position of Fig. l, omitting the airtubes f and t. Fig. 3 is a section of the airvalve to theright of the line g h,Fig. l,
omitting the pieces l w w &c. Fig. 4 is an end elevation of the piece V, showing the inner face.
A a-nd B are submerged water-chambers, into .which water is admitted through the valves a and b. The water passes out through the short pipes G and D, which are screwed into the top of the chambers, and reach nearly to the bottom. These pipes connect with the discharge-pipe P by means of the connectingchamber E and the valves c and d, which prevventwater from flowing back. Now, if air is forced into either of the water-chambers from the top, the water will be forced into the dischargepipe P, through which it may be led anywhere it may be desired. Air is forced, by means of a condenser, into t-he air-tube't, which may be of any desired length, so that the condenser may be placed wherever it is `most convenient to apply the power. The piece V is connected, at the aperture n, with the air-tube t by means of a flexible tube, f. The piece V turns upon its axis, ac, and is .pressed by a spring or weight (not shown in drawing) against the flat surface of the piece F.
iioat, H, in the chamber A. The water being forced out of A, the float drops, turning the piece V so that the aperture a is turned away from the aperture m and brought opposite to `another aperture, u, which goes a little way into the piece F, turns and connects with the tube U, leading to the top of the water-chamber B. The piece V has also two other apertures, s and z, so situated that when the aperture n is opposite to the aperture m the aperture z will be opposite the aperture u, and
when the aperture nis opposite the aperture a, s' will be opposite m,- so that while air is being forced into the chamber A the air in B may escape through the apertures u and z, and when forced into B through n and u that in A may escape through m and s, thus allowing one chamber to fill while the other is being emptied. When water refills the chamber A, the iloat H rises and turns the piece V back to its former position. y
The chamber B is only needed to keep the iiow oi' water constant. if the tube U were either removed or'obstructed, the chamber A would act alone, and the flow would be interrupted while refilling., lhe float His made to reach nearly from top to bottom of chamber A, allowing only the necessary movement.
In order to prevent the iioat from falling or rising before the proper time, an adjust-able weight, w, is attached to a rod, q, screwedinto the top of the piece V, Figs. 2 and 1, at right angles to the arm l. This weight w resists the tendency of the iioat to fall or rise, and offers the greatest resistance at starting. Indeed, after passing a vertical line" through fc, the weight assists the float in its movement,
so that when the iioat overcomes the starting resistance of w it 'falls or rises at once. 11n order that the float .may act with equal force in either direction, its specic gravity should be Butif its speciic gravity exceeds the float may be made to act with equal force in either .direction .by-subjecting the "rod 'r :to a
' suitable tensionA `by nleans'of iran .adjustable weight, w', attached to a rod screwed into the piece V opposite to the arm l.
By making the float just heavy enough to sink, the rod r may be replaced bya Wire, and,
nate admission and escape of air to and froxn the water-chamber ofa pneumatic pump.
