JOEL R. BASSETT, OF CINCINNATI, OHIO.

VALVE FOR PUMPS.

Specification of Letters Patent No. 9,046, dated June 22, 1852.

YTo all whom it may concern.'

Be it known that I, JOEL R. BAssE'rT, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Double-Acting Pumps; and I do hereby de- Clare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, made part of this specification.

The device I use consists of a cylindrical box-valve (the top and bottom of which are slightly conical) and a valve-chest adapted thereto, each having the parts necessary to the operation of a double acting lift and force pump, thus obtaining from a single valve deriving its motion from the outflowing and inflowing currents the result for which several separate valves have hitherto been needed.

In the annexed drawings Figure 1 is a perspective view of the pump, the valve and chest-cap being detached; Fig. 2B, is a horlzontal section thro-ugh the water-bed, valve and valve-chest looking downward, and Fig. 2A is a top view of the chamber-cap with one opening closed by the valve and the other opening unclosed.

The same letters refer to like parts throughout.

(a) is a double-acting pump cylinder of usual construction; is the usual sidepipe.

The water bed seen exteriorly at (0), Fig. 1, consists of the two passages (0') (0), Fig. 2B, one of which (0') communicates with the bottom of the cylinder (a) and the other (0) through the side pipe (o) with the top of the cylinder (a). Each of these passages opens into the chest (CZ), as seen in the instance of the passa-ge (0) at (e), Fig. l. This chest is circular and with a view to wear and adjustment slightly conical, tapering downward, and has fitted nicely to its interior a correspondingly formed box-valve (f) having openings (g) (g) in it-s side corresponding to those in the chest. These openings (g) (g) have communication with the suction pipe below by means of apertures (t) (z) in the bottom of the valve, and these apertures, through corresponding openings (one of which is seen at (L) in Fig. 1) in the chest-bottom (Z), and with the escape-pipe above by means of apertures (i) (2) through corresponding openings (im) in the cap (m), so that as regards the valve, when the lower aperture (t) on one side is in communication with the aperture (M) in the flow, the lower aperture on the other side of the center of the valve is closed and at the same time the upper aperture of the valve is shut off from (im) in the cap and the aperture (z') corresponds with the aperture (zw) and vice-versa on the reverse stroke.

l/Vhen the pump is operated the currents forced therefrom or admitted thereto strike opposing vertical sides of the box-valve openings and act in concert to give the valve a vibratory motion limited by the pin working in the groove (7n) the motion being a little more than double the width of the openings or (7L), but inasmuch as the current due to the forcing stroke of the pump somewhat more than counterbalances the current due to the column raised by atmospheric pressure, 0r in common parlance, to the lifting stroke of the pump, it is the current forced out of the pump that determines the motion of the valve. In the drawings the current due to atmospheric pressure is supposed to be rising up through the opening (/L) overlying the opening (z/) and passing through the openings (g) and (e) into the waterway (0), and the current due to the forcing stroke is passing out from the waterway (0) through the openings (g) and (vY) into the usual air-vessel from which the discharge of the water vis made in the usual way.

What I claim as new and desire to secure by Letters Patent of the United States is- The device consisting of a cylindrical box-Valve with its induction openings (77,) L) and its side or waterway openings (g) g) and its eduction openings (2), and of a valve-chest adapted thereto with its induction and side, or water-way, and eduction openings corresponding to the openings in the valve-box; the whole, in connection with the usual waterways and barrel of a double-acting pump, furnishing the parts necessary to the operation of such a pump; thus obtaining from a single valve, deriving its motion from the outilowing and inflowing currents, the result for which several separate valves have hitherto been needed, substantially in the manner described.
