IMPROVEMENT IN VERTICAL STEAM-PUMPS.
Specification forming part of Letters Patent No. 206,457, dated July 30, 1878; application filed December 20, 1877.
To all whom it may concern:
Be it known that we, HENRY A. JAMIESON and WILLIAM FOSTER, of the city of Brooklyn, county of Kings, and State of New York, are joint inventors of an Improvement in Vertical Steam-Pumps, of which the followin g, taken in connection with the accompanyin g drawing, is a full, clear, and exact description. 1
Our invention more particularly applies to deep well and mine pumps, where the steamcylinder of the pump is located at the surface or top of the well or shaft, and the watercylinder of the pump placed within a suitable distance of the water-in some cases two or three hundred feet below the surface of the earth.
Pumps constructed in this way have advantages over the ordinary steam-pump. As the steam-cylinder of the pump is at the surface the pump can be started at any time by letting on the steam, although the water-cylinder be submerged in water.
In the use of the pumps above described, however, difficulties and inconveniences have been experienced which our invention fully overcomes. The said pumps have been found to work with very unsteady motion, the weight of the piston and piston-rods causing the downward stroke to be too rapid and the upward stroke to be retarded to the same extent. To remedy this defect is one of the objects of our invention.
In case the steam and water cylinders are is to balance. In this cylinder B is the balancing-piston O, which plays in the cylinder B, and is connected with the main piston-rod I. The steam-pipe D connects the balancingcylinder B with the main steam-pipe of cylinder E. F is the main steam-piston, which plays in cylinder E. The pipe G connects the main steam-cylinder E with the water-cylinder K. The pipe Gr also answers as the deli very-pipe or discharge for the water from and through the water-cylinder K. Secured or cast on the pipe. G are the rungs or steps H, which serve as a ladder to descend into the well or shaft.
The operation of our improvement is as follows: The steam from the steam-pipe or steamchest passes through the pipe D, which con nects with the balancing-cylinder B below the piston O, at the bottom of balancing-cylinder B, the upper end of which is left open to the atmosphere. The pump, when the piston F and piston-rod I are making their downward stroke, is thus balanced by the steam passing through the pipe D and pressing on the under side of the piston O in balancing-cylinder B. On the upward stroke of the piston F and piston-rod I the steam which passes through the pipe D from the steam-pipe or steam-chest exerts a force equal to the weight of the piston F and piston-rod I, and thus prevents their motion from being too slow.
The motion of the piston F and piston-rod I in their upward and downward stroke is thus made uniform, and all unsteadiness in the action of the pump avoided.
The auxiliary or balancing cylinder B may be placed below the main cylinder E instead of above, as shown in the drawing.
The pipe G is made in suitable lengths, which are secured together, and thus firmly connects the steam-cylinder E with the water-cylinder K, thus preventing the cylinders from changing their relative positions, while at the same time it acts as a delivery or discharge pipe for the water from the water-cylinder K, and as a ladder by which to descend into the well or mine.
Having thus described our invention, what I In testimony whereof we have hereunto set We claim, and desire to secure by Letters Patour hands this 18th day of December 1877. ent, is
In connection with a Vertical steam-pump, a balancin g-cylinder and piston, with the necessary steam and air pipes for balancing and equalizing the stroke of pump, substantially In presence of as described, and for the uses and purposes CHARLES G. 00E, above set forth, LoUIs W. Fnos'r.
HENRY A. JAMIESON. WILLIAM FOSTER.
