UNITED STATES PATENT EEicE.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 34,101, dated January 7, 1862.
To all whom it may concern:
Be it known that I, WARREN S. BAETLE, of Newark, in the county of Vtfayne and State of New York, have invented a new and Improved Mode of Constructing Pumps; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
Figure l of the drawings is a view of theA pump with the several parts connected. Fig. 2 represents the cylinder or barrel disconnected for the purpose of showing the valve a. Fig. 3 represents the piston with the pistonrod B detached from the head D and the valve E removed from its seat in the head.
At the lower end of the cylinder or barrel is a valve a, Fig. 2, made in any convenient manner for the purpose of supporting and preventing the return of the column of water when having risen into the cylinder. In the piston-head D, Fig. 3, the cross-section of which is sufficiently large to fill an equal section of the caliber of the cylinder, is a valve, (shown at E, Fig. 3,) which closes the head in its upward movement and may be made in other forms than that exhibited in the draw' ings. In the upper section of the piston-head and above the seat of the valve are orifices b o, Fig. 3, for the passage of the water from the valve into both the interior of the pistonrod and the space surrounding it, and also for the passage from the space surrounding the rod into the interior of it; and for the purpose of securing the passage in the manner mentioned the orifices named are made of such length that when the valve is raised a coinmunication both above and below it is con! temporaneously opened between the interior of the piston-head, the interior of the pistonrod, and the space surrounding it. At the lower end of the piston-rod is a cross-bar e, Fig. 3, to regulate the height to which the valve in the piston-head may rise at the time ot' the downward stroke.
' For the purpose of furnishing an air-chamber to keep up the continuity of the discharge when the piston is at the dead-points, the piston-rod7 the upper end of which is shown at d, Fig. l, is made hollow, as shown at B, Fig. 3, and is closed at the upper end and left open at the lower. The piston-rod during the downward stroke operates as a plunger and forces through the discharge-aperture a portion of the Water that is in the cylinder at the end of the upward stroke, and to render it most effective for this purpose the area of its cross-section should be about the same as the area of the space between the exterior of the rod and the interior of the cylinder.
At f, Fig. l, is shown the admission-conduit, and at h, Fig. l, the discharge-aperture, both of which may be varied from a horizontal to a vertical or oblique position.
The operation of the pump is as follows: By the upward stroke of the piston the valve in the piston-head closes and the water rises by the force of atmospheric pressure through the valve c, Fig. 2, and the largest portion of the water, which is then above the valve E in the piston-head, is forced through the dischargeaperture and a small quantity of it into the air-chamber in the interior of the piston-rod, by which the air therein is more or less compressed. At the end of the stroke the air in the chamber reacts and continues the pressure upon the column of water within the cylinder and so keeps up the continuity of the discharge until the commencement of the downward stroke. By the downward stroke the lower valve a, Fig. 2, is closed and the water above it is forced through the valve E, Fig. 3, in the piston-head out through the apertures b b, Fig. 8, into the space between the piston-rod and t-he interior surface of the cylinder, and the piston-rod at the same time operating as a plunger displaces from the cylinder a volume of water equal in measure to the cubic dimensions of the rod less the small quantity forced into the air-chamber, which at the termination of the stroke is displaced by the reaction of the air compressed therein and made to keep up the continuity of the discharge until the commencement of the next stroke.
This pump is simple, having but two valves and a single piston-head, and yet combines the principles of a double-action lift and force pump with the additional advantage of an E, and head D, with the cylinder in which air-chamber to keep up the continuity of the they act, constructed and arranged substandiseharge and to prevent the concussion piotially as described.
