IMPROVEMENT IN DOUBLE-ACTING FORCE-PUMPS.
Specification iormin g part of Letters Patent No. 140,819, dated July 15, 1873 5 application iiled April 5, 1873.
`To all whom tt may concern:
Be it known that I, J oHN I). FLANDEEs, of Vergennes, in the county of Addison and State of Vermont, have invented a new and useful Improvement in Force-Pumps, of which the following is a specification:
The invention consists in the improvement of force-pumps, as hereinafter described and pointed out in the claims. A Figure 1 is a side elevation of my improved pump. Fig. 2 is a transverse section on line fe a: of Fig. 3. Fig-3 is a horizontal section on line y y of Fig. 2. Fig. 4 is a cross-section of the longitudinally-divided barrel.
Similar letters of reference indicate correspondin g parts.
A represents the cylinders, which are arranged on each side of a wide bed-frame, B.
` (l represents the suction-pipes, of which there chamber. is apipe from which the water l l I 'is discharged from the box I, and M is an airchamber.
For packing the pistons I propose to have the barrels N, in which they work, divided in two or more longitudinal parts with lap-joints at the edges, so that they can contract and expand a little without opening seams for the escape of water, and I provide a small annular channel, O, surrounding the barrel, in which I maintain a high degree of pressure by Water admitted through a pipe-connection, P, from any suitable head or source, and, to prevent this water from leaking past the barrel, I arrange packin g-rin gs in the channel. To hold the barrel in position and allow them to be free to expand and contract, I form notches R inthe shell in ther cylinder, and lugs in the barrels, which project into the notches and hold the barrels against the end motion.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The arrangelnent of the cylinders A, bedframe B, suction-pipes O 1), discharge-pipes F G, discharge-box I, and the air-chamber, substantially as specified.
2. A sectional piston-barrel, contracted upon the piston for packing it by hydrostatic pressure, applied in the manner described.
JOHN P. FLANDERS.
