IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. elllfll@ dated November 8, 1864.
To all whom it may concern.-
Be it known that I, PHILTP C. Rowe, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure lis a horizontal section of my invention taken in the line .tw, Fig. 2; Fig. 2 a longitudinal vertical section of the same taken in the line y y, Fig. l, Fig. 3, a transverse vertical section of the same taken in the line a e', Fig. l.
Similar letters oi' reference indicate corresponding parts.
This invention relates to a new and improved pump of that class in which a diaphragm of in dia-rubber or other suitable material is used as a piston or plunger, and which is double acting. Y
The invention consists in the employment or use of two chambers arranged with valves and diaphragms, the latter bein g operated in a novel way, and the chambers provided with air vessels, all arranged as hereinafter fully shown and described.
A` represents a base-plate, on which the pump rests; and B B are two cast-iron plates, which have each two conical cavities, O, in them, which when the plates are secured together form the pump-chambers, as shown in Fig. 2. Between the two plates B B there is secured a diaphragm, D, which serves as the plungers or pistons of the chambers C C the diaphragm ot'each chamber having a rod, l, secured to it by nuts c, said rods passing up through startling-boxes b at the apices ot the cavities of the upper plate, B, and each rod E having a rack, c, formed in it, into which pinions el d gear,said pinions gearing into a central toothed segment, F, having a handle, G, attached to it. By this arrangement the two diaphragms are worked alternately up and down by oscillating the handle G, as will be fully understood by referring to Fig. 2.
Each plate B is cast with two radial channels, e e c e', which serve as water-channels, and form a communication between the chambers O C and the induction and eductiou tubes H I, which communicate with air-ves sels J J, the eduction-tube I communicating with the vessel J andthe induction-tube H communicating with the vessel J. (See Fig. 3.) Below the air-vessel J there is a valveboX, K, which is divided into four compartments, j', by partitions g', each compartment having a valve at its bottom opening up ward. The valves g g communicate with the channels e e, which lead from the indue tion tube.
The channels e e c e are not in line with each other, as will be seen by referring to Fig. 1, the channelsin the lower plate,B, being indicated by dotted lines. B y this means the passages of the two compartments in each chamber are made to communicate with their proper valves.
In the bottom oi' the air-vessel J there are placed four valves, t', which communicate with the eduction passages or channels e e, which lead from the chambers O O to the air vessel J with which the eduction-tube communicates. y
The operation of the pump will be readily understood. The piston-rods E E are raised and lowered alternately by oscillating the handle G, as previously referred to. As each diaphragm rises a suction is produced in the lower parts of the chambers C, and the valve g, which communicates with the inductionpassage c of the lower part, opens, the water passing up into said part ot' the chamber, while the valve g, which communicates with the induction-passage ot' the upper part ofthe other chamber, opens and admits the water into said part, it being understood that the diaphragme ofthe two chambers move or work simultaneously in opposite directions. Vhile the Water is being drawn into one of the compartments ot' one chamber it is forced out from the other through its eduction-passage ef into the air-vessel J and passes out through the tube l.
Thus it will be seen that each compartment C is double acting, and, as two compartments are used, a constant and uniform stream will be forced or ejected from the tube I.
The air-vessels perform their usual function and aid in causing the water to iiow with a uniform volume or stream.
I do not claim t-he employment or use of an elastic diaphragm for pumps7 as they have tubes H I, provided with valves g i, and all been previously used; but arranged to operate substantially as and for I do claim as new and desire to secure by the purpose herein set forth. Letters Pateut- PHILIP c. ROWE.
