PUNIPING-ENGINE.
SPECIFICATION orming part of Letters Patent No. 700,974, dated May 27, 1902.
Application iiled May Z9, 1901. Serial No. 62,426. (No model.)
To all whom it may concern:
Be it known that I, HERMAN NIELSEN, of South Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Pumping- Engines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to ro make and use the same.
My invention relates to an improvement in duplex pumping-engines, the objects of the invention being to cheapen the construction of such engines, to avoid the use of valves which are liable to stick, to provide for the positive opening of the ports, to minimize the weight and size of such pumping-engines, and to produceapumping-engine for feeding boilers and tanks, compressing air, and for other purco poses which shall be eiectual in all respects in the performance of its functions.
With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of t5 parts, as hereinafter set i'orth, and pointed out in the claims.
In the accompanying drawings, Figure 1 is alongitudinal sectional view. Fig. 2 is a view on the line as n; of Fig. 1. Fig. 3 is a view on 3o the line y y 01": Fig. 1. Figs. 4 and 5 are diagrams showing the courses taken by the live steam and exhaustunder different conditions during the operation of the apparatus.
A represents a casting comprising twin 3 5 cylinders l 2 of the motor portion of my improved pumping-engine, and B indicates a similar casting containing cylinders 3 4 of the water or pumping end of the apparatus. The castings A and B are disposed in alinement 4o with each other and spaced a short distance apart by means of two sleeves 5 5, which serve as bushings for piston-rods 6 7, connecting the pistons S 9 in the cylinders 1 2 with the pistons 10 l1 in the cylinders 3 4. The castings A and B are provided with flanges 12 13, through which bolts 14 are passed for rigidly securing the castings together.
The piston 8 is provided near its inner end with two curved ducts 1`5\16, the respective 5o ends of each terminating at the periphery of the piston at points equidistant from each other. Near the outer end ot' the piston 8 two ducts 17 1S are located. These ducts are curved in opposite directions, so that they will pass each other without communicating, and are arranged at right angles to each other. Each duct 17 18 terminates at the respective ends at diametrically opposite points on the periphery of the pistons, the difference in the disposition of these ducts and the ducts 15 1G 6o being clearly illustrated in Fig. 2. The piston 9 is provided with ducts arranged in precisely the same manner as above described in connection with piston 8, the ducts near the in- \ner end of the piston 9 being designated on the `65 drawings by the reference characters 15 1G and those near the outer end by the characters 17 18. In the casting A between the cylinders 1 2 four ducts 19, 20, 21, and 22 are located. The duct 19 communicates at one end 7o with the center of the cylinder 1 and at" the other end with/the outer end of the cylinder 2. The duct 2O communicates at one end with the inner end of the cylinder l and at the other end with the center of the cylinder 2. The ducts 21 and 22 are located below the ducts 19 20, the duct 21 communicating at its respective ends with the outer end of cylinder 1 and the center of cylinder 2, and the duct 22 communicating at its respective 8o ends with the inner end of cylinder 2 and the center of cylinder 1. Live-steam-inlet ducts 23 are located in the casting outside the cylinders and communicate with the center of each cylinder. Exhaust-ducts 24 are located 85 in the casting A at the other side of the cylinders and communicate with the center of each cylinder.
The pump or water end of the apparatus is constructed exactly the motor devices 9o above described, except the parts are made smaller and the Various ducts are arranged in reverse order, the suction-ducts of the pump corresponding with the exhaust-ducts of the motor and the steam-ducts of the motor corresponding to the outlet-ducts of the pump. To be more specific, the piston 10 is provided near its outer end with curved ducts 25 26, arranged the same as the ducts 17 18 of the piston 8, and the piston 10 is provided roo near its inner end with curved ducts 27 28, disposed in a manner the same as the ducts 16 of piston 8. The piston 11 is similarly v provided with ducts 29 30 and 31 32, arranged in the same manner as the ducts in the piston 10. The castingB is provided with ducts 33 34 and 35 36 between the cylinders, the
same as the ducts 19 2O and 21 22 in the casting A. The casting B is also provided with inlet or suction ducts 36 and outlet-ducts 37, arranged in the same manner as the exhaustducts 24 and the inlet-ducts 23 in the casting A.
With the parts in the positions shown in Fig. 1 the piston 8 has just finished its stroke, the steam for causing this stroke of the piston entering from one of the inlet-ducts 23 and passing through the duct 17l of piston 9 and thence by way of the duct 21. to the outer end of the cylinder 1. During this stroke of the piston 8 the exhaust in front of it will escape by way of duct 20, passing from thence through the duct 18 in the pistou 9 to one of the exhaust-ducts 24. When the piston 8 shall have reached the position shown in Fig. 1, the ports of the ducts 18 and 22 will register and live steam entering from one of the ports 23 will flow through the duct 18 in piston 8 and the duct 22 in the casting to the inner end of the cylinder 2 behind the piston 9 and cause the latter to make its outward stroke. As the piston 9 makes its outward stroke the exhaust in front of it will escape throught the duct 19 and thence through the duct 17 to the exhaust-duct. When the piston 9 reaches the end of its outward stroke, the ports of the ducts 15 therein will register witlrthe ports of the ducts 23 and 20, as shown in Fig. 4, thus permitting steam to pass from the duct 23 through duct 15 in piston 9 and thence through the duct 2O to the inner end of the cylinder 1 behind the piston 8. This will cause the piston 8 to make its outward stroke, during which the exhaust in front of it will flow through the duct 21 in the casting A and the duct 16 in the piston 9 to the exhaust-duct 24, as shown in Fig. 4. l/Vhen the piston 8 reaches the end of its outward stroke, the ports of the duct 15 in said piston will register with the ports of ducts 23 and 19 'and steam will iiow from the duct 23 through the duct 15 and thence through the duct 19 to the outer end of the cylinder 2 behind the piston 9, as indicated in Fig. 5. This will cause the piston 9 to make its inward stroke, during which the exhaust in frontof it will flow through the duct 22 in the casting A and duct 16 in the piston 8 to the exhaust-duct 24. When they piston 9 reaches the end of its inner stroke, the duct 18 therein will register with ports of ducts 2l and 23 and steam will flow from the duct 23 through the duct 18 in the piston 9 andv ton 9 to the duct 24. The movements of the pistons 8 9 from the positions shown in Fig. 1 and back to these positions have now been described, from which description it will be seen that said pistons follow each other, one piston always reaching the end of its stroke before the other starts.' The pistons 8 9 being connected directly with the pistons 10 11, precisely the same movements will be imparted to the latter, andthe water will enter and pass through the various ducts in the pistons 10 11 and casting B in exactly the reverse order to the entrance and exhaust of steam to and from the pistons 8 9 and casting A. Thus at each outward stroke of each piston 8 9 water will flow through one of the pistons 10 11 and enter the cylinder in which the other piston is located, and at each inward vstroke of the pistons 8 9 water will be expelled from one cylinder 3 or 4 and after passing through the piston located in the other cylinder will escape through the outlet-duct of the casting B.
The ducts 19, 20, 21, and 22 are connected with the extreme ends of the cylinders by means of ducts 38 (provided with automatic check valve 39) for purpose of forming a steam-cushion at each end of the cylinder or piston stroke and also .providing means of steam-inlet to start the pistons.
My improved pumping-engine is Very simple in construction, comprises but few parts, employs no valve mechanism aside from the pistons themselves, is sure and accurate in operation, occupies very little space, is very light in weight in comparison with the amount of work which it will perform, and is effectual in all respects in the performance of its functions for pumping water, air, or even semiiiuid materials, such as vaseline, tar, dac.
Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth.
1 Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. A duplex pumping-engine comprising a series of water-cylinders and pistons therein and a series of steam-cylinders and pistons therein, each water-piston connected with a steam-piston land ducts controlled by said pistons, one steam piston controlling the ducts leading to and from the other steampiston.
2. A duplex pump comprising two series of cylinders, one series for water and the other series for steam, pistons in said cylinders, the water-pistons `connected with the steampistons and ducts controlled by said pistons, one steam-piston operating to control the movements of another and the movements of the water-piston connected with the latter.
3. A pumping-engine comprising two pairs of twin cylinders, each provided with inlet and outlet ports similarly constructed, pis- IOO IIO
tons in said cylinders, said pistons having ducts therein cooperating with the ducts of the cylinders, the ducts in all the pistons being similarly disposed, the ducts in the pistons of one pair arranged in reverse order to the ducts in the pistons of the other pair, and piston-rods connectingthe pistons of one pair with the pistons of the other pair.
4. In a pumping-engine, the combination with two cylinders provided with two pairs of ducts, one pair of said ducts connecting the center of one cylinder with the ends of the other cylinder, and the other pair of ducts connecting the center of the last-mentioned ing witnesses.
