PUMP.
SPECIFICATION forming part of Letters Patent No. 226,005, dated March 30, 1880.
Application filed August 27, 1879.
To all whom it may concern:
Be it known that I, JAMES A. SINCLAIR, of Bridgeport, in the county of Belmont and State of Ohio, haveinvented certain new and useful Improvements in Pumps; and I do hereby declare that thefollowingis afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form apart of this specification.
This invention relates to improvements in combined lift and force pumps and it consists in an inner casing of peculiar form placed within the stock of an ordinary pump, as will be hereinafter fully explained, and pointed out in the claims.
In the drawings, Figure 1 is a vertical section of the pump-stock and inner casing. Fig. 2 is a vertical section, made on a line at right angles to the line on which the section of Fig. 1 is out, and it shows the inner casing only partially in section. Fig. 3 is a detail view; and Figs. 4. and 5 are modifications.
a is the pump-stock, having the handle a, piston-rod a, lifting-piston a check-valve a, and discharge-spout a all of ordinary construction and arrangement. I) is an inner casing composed, preferably, of the outer shell, I), and inner shell, b which are united at their top ends, so as to form a chamber, b closed air-tight at its top end by a cap, (I, and so as to provide a central slot or opening, I), in the upper end of the inner casing, through which the piston-rod (1. passes downward into and through the said inner shell, W, to the piston a The top end of the casing 11 is placed near the top of the stock, sufficient space being allotted for the free play or stroke of the inner end of the handle a, to which is affixed the upper end of the piston-rod a The outer sh ell, b, is made to fit the bore of the stock a, so that no water will pass upward on its outer side. Its lower end reaches down the stock to a point flush with the upper side of the discharge-vent in spout (1. It may be, if desired, extended below the spout, in which case a suitable opening must be made through it to permit the water to flow into the said spout. Theresultis the same whether extended to or below the spout, as above explained.
The inner shell, W, is open at its upper and lower ends, and extends down ward from a point above the spout a to a point at or near the limit of the upward stroke of the piston (0 and it is surrounded by a space, I), through which the water reaches the spout a and the air-chamber b In a pump designed for use in theordinary wells, where the water is received into "essels directly from the spout a I employ the abovedescribed arrangement of the inner shell; but where it is designed to throw the water to a higher level, or where the wateris to be thrown through a'hose attached to the spout, the inner shell, b need not be extended below the said spout. Where the free flow of the water is confined the pump will act, as described, even if the lower end of the inner casing be flush with or above the spout a and the play of the pis ton c be also above said spout.
- On the piston-rod (1, is fixed a force-piston, 0, arranged to play up and down in the inner shell, b simultaneously with the play or stroke of the piston-rod a d is a vent-hole, made through the stock a and outer shell, I), in the upper end of the airchamber If. It is closed when desired by the plug d.
The operation of the device will be readily understood. The water is liftedby the piston a ,.and is forced upward to the spout a and part way up into the chamber W. The piston 0 also acts to draw the water after it, so as to fill the space below it in the shell b On the reverse movement of the handle the check valve (1, prevents the water from falling back into the well or cistern, and the action of the air in the chamber 11 maintains a constant flow of water out of the spout It will be readily seen that the casing b can be made of a size to suit the bore of any ordinary pump-stock, and can be inserted without difficulty.
By means of my improvements old pumps, which have become almost useless by reason of being cracked or otherwise injured, may be made as good as new, so far as the operation of raising water is concerned.
The outer shell, b, may be extended downward to any desired length and make a lining for the bore of the pumpstock; but this is only necessary where there are cracks in the stock which need to be covered to prevent air from getting into the bore or to prevent water from flowing out.
I have hereinbefore described a casing composed of a double shell constructed with a slot in its upper end but it will be understood that the said slot is made to provide for the neces sary lateral movement of the stiff piston-rod as the latter is operated by the handle a.
When the slot is used the inner shell hasits upper end flattened on'lines parallel with the vertical plane in which the handle plays, which flattening gives to the opening the necessary elevation for the play of the piston-rod.
Instead of the slot, a small hole, d, may be made through the cap which unites the upper ends of the shells. The piston-rod in this case would be made of two parts and coupled or hinged together above the cap. The hingejoint would permit the necessary vertical mo vement of the handle. The hole through which the piston works should not be packed so as to render the upper end of the inner shell airtight.
on. the top of the inner shell alone, the outer shell being dispensed with. When inserted in the stock its cap closes the bore and gives the air-tight chamber b surrounding the inner shell.
What- I claim as my invention isl. The combination, with the pump-stock a and piston -rod having piston a on its lower end, of the shell b and shell b ,-uuited air-tight at their top ends, so as to provide an air-chamber, [1 between them, and an opening, 1), into the upper end. of the inner shell, b and the piston c, fixed on the rod a and arranged to play up and down in the said inner shell, substantially as and for the purpose set forth.
2. The shell 11 having the cap (I attached to its upper end, of a size to fit air-tight in the pump-stock a, and provided in its center with a hole for the piston-rod a to pass through, in combination with the pump-stock a, the piston-rod (0 provided with the piston a at its lower end, and the force-piston 0, attached interlnediately between its'ends and having its stroke in the shell b the said shell b being adjustable at any desired elevation in the pump, substantially as and for the purposes set forth.
In testimony that I claim the foregoing as my own Iatfix my signature in presence of two witnesses.
JAMES A. SINCLAIR.
