STATES JOHN NORTH, OF NEW YORK, N. Y.
IMPROVEMENT IN STEAM'PUIVIPS.
@pecification forming part of Letters Patent No. l34l,d@ll, dated December 31, 1872.
To all whom it may concern:
Be it known that I, JOHN NORTH, of the city, county and State of New York, have invented a new and Improved Pump, of which.
on the line K K, Fig. 1.
Similar letters of reference indicate corresponding parts.
This invention has for its object to dispense with the valve arrangements now used in reciprocating pumps; and consists in the use of a perforated cylinder placed within the pumpcylinder, but embracing the plunger, and vibrated to bring its apertures in line with the several ports in the requisite succession.
A in the drawing represents the pump-cylinder. a a are the outlet-ports; b and b the inlet-ports of the same, leading, respectively, 'from the inlet-pipe B and to the outlet-pipe C. D is a cylindrical shell fitted into the cylinder A and connected at its projecting stem d, or at any other convenient place, with suitable mechanism for rocking it within A. The cylinder D has four slots cut through it, of which two, diagonally opposite each other, can be in line with two of the ports. Thus,
in Fig. 1, the slots 2 and 3 of the cylinder 1) are shown to be in line with the ports a and b, respectively. The remaining two ports are meanwhile closed by the cylinder D. When the cylinder is rocked its slots 1 andet will come in line with the ports a and b respectively, opening the same, while the ports a and b will be closed. The cylinder D serves thus as a convenient and a simple substitute for the usually-complex valve mechanism of pumps, and is not liable to get out of order. E is the pump-plunger, reciprocating within the cylinder D and properly packed to fit tight therein. Its motions are so proportioned to the vibrations of the cylinder D that at or near the end of each stroke of E the said cylinder is rocked to reverse.thearrangement of ports, and thereby effect the requisite reversion of the plunger.
Having thus described my invention, I claim as new and desire to secure by Letters Pat,
ent
The cylinder D having ports 1 2 3 4, combined with the piston E, the one rocking and the other reciprocating within the pump A, arranged as and for the purpose specified.
J OHN NORTH.
