ELECTRIC PUMP.
$PECIFICA'I'ION forming part of Letters Patent No. 581 ,204, dated April 20, 1897. Application filed October 10, 1896. Serial No. 608,488. (No model.)
To aIZZ whom it may concern:
Be it known that L'Brnenn HEFTYE, a citizen of the Republic of Mexico, and a resident of TuXpan, in the Province of Vera Cruz and Republic of Mexico,have invented certain new and useful Improvements in Electric Pumps; and I do hereby declare that the following is a full, 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, which form a part of this specification.
My invention relates to improvements in electric pumps; and its object is to provide an improved construction whereby the usual electroinotors are dispensed with, the pumpcylinders and pistons themselves constituting an electromagnetic engine.
In carrying my invention into effect I employ two pump-cylinders, each wound with insulated electric wires, through which, when the pump is in use, passes a constantelectric current in one direction, so that the polarity never changes. The cylinders thus form hollow electromagnets or solenoids, in each of which is located a piston, also wound with in-' sulated wire, through which an electric current passes, forming electromagnets which are independent of the cylinders. The current at each stroke of the pistons is reversed, so
as to shift the poles, whereby the pistons arereciprocated. These pistons are connected together and are provided with a packingring of non-magnetic material which separates them from the cylinders, yet makes them a water-tight joint. Means are provided for shifting the poles of the pistons at each stroke thereof, so that they'will be alternately attracted toward opposite ends of the cylinders to cause their reciprocation.
The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.
Having thus briefly outlined the nature of my invention, I will now proceed to describe the same in detail, referring to the accompanying drawings, in which Figure l is a longitudinal sectional view of an electromagnetic pump constructed in accordance with my invention. Fig. 2 isatransverse sectional View, on an enlarged scale, of the commutators, showing the means for shifting the poles of the pistons. Fig. 3 is a horizontal sectional view of the same. Fig. 4. is an end view. Fig. 5 is a side elevation of the governor for diminishing the spark in shifting the poles.
In the said drawings the reference 11nme'rals 1 and 2 designate two cylinders, which may be provided with a lining or not, as may be desired. Each of these cylinders is provided with an inlet-pipe 3, communicating with a horizontal passage 4, leading to near each end of the cylinder and provided with oppositely-working valves 5. Diametrically opposite the cylinders are provided with eductionvalves 6, passages 7, and discharge-pipes S, which communicate with the air-chambers 9. These cylinders are also provided with manholes 10 and covers 12 for affording access to the valves.
The parts just referred to may be of any ordinary orsuitable construction as they form no part of my present invention.
The cylinders are provided with hollow or motor coils 13, (shunt or compound winding) connected as if they were one coil, in order to make the cylinders hollow electromagnets or solenoids. There should be two of these coils or bobbins for each cylinder electrically connected with each other, so as to afford a space for the suction and discharge pipes. The coils of said cylinders are respectively connected with a dynamo or other electric generator, and a continuous current is always passing therethrough when in use in one and the same direction, the poles never being changed or shifted. The cylinder-heads 1 and 2 form the pole-pieces. The cylinders are connected by a yoke 14, of brass, bronze, or other non-magnetic metal. Located in said cylinders are pistons 15, of soft iron, connected by means of a piston-rod 16. I prefer to employ two piston-rods, so as to prevent the pistons from turning, one or both of which has a central longitudinal hole for the passage of the wires, hereinafter described. These pistons are provided with bobbins or coils 17, connected together by wires 18 and 19, running through the hole in the pistonrod, which coils are electrically connected with a dynamo, as hereinafter described, so as to form electromagnets independent of the cylinders. Each piston has two iron heads 20, provided with phosphor-bronze packingrings 21. These rings are necessary to keep the piston-heads out of contact with the magnetized cylinders and also for preventing water from passing.
For changing the current or shifting the poles of the pistons I provide the following means: The numeral 23 designates a horizon tal metal tube screwed on the piston-head of cylinder 1. Located inside of this tube is another tube 22, of hard rubber or other insulating material, to which are fastened two copper c0mmutator-strips 2i and 25, approximately semicircular in cross-section with a space between the edges thereof. The tube passes through a stuffing-box 26 in the cylinder-head. The commutator strips or segments are electrically connected with the bobbins or coils of the pistons, being the two terminals thereof.
The numeral 27 designates an outwardlyprojecting horn consisting of a metal tube having its inner end enlarged, forming a cylindrical chamber 28, which is screwed or otherwise secured to the cylinder-head The outer end of the horn is closed by a screwcap 29, formed with two holes 30, through which the positive and negative wires 31 and 32, electrically connected with a dynamo, pass. Secured to this cap is an inwardly-extending brass tube 34, which is about the same length as tube 23 and which is located in the tube 22. The latter tube is slightly longer than the stroke of the pistons, in order to allow for a screw-head on the end for fastening it to the piston-head.
The feed-wires 3i and 32 pass through holes in tube 34: and run along the inside thereof to near the inner end, where they pass through nipples 35, of insulating material, to bindingposts 36 on the outside of the tube 34. Connected with these binding-posts are brushes 37 and 38, which contact, respectively, with connecting-rings 39 and 40 on the outer face of a rotatable disk 41, loosely mounted or journaled on a stud-shaft $2 in the inn er end of the tube 3% so as to freely turn thereon. Secured to this disk, diametrically opposite each other, are two cams if each consisting of a triangular metal plate, which is curved longitudinally so as to conform to the periphery of the disk and screwed or otherwise secured thereto. The frontand rear edges of these cams are adapted to be alternately struck by pins 4(5) and 46, secured to the tube 23, as the latter is reciprocated by the piston to which it is attached, thereby oscillating the disk. Pivoted to the inner side of the disk are brushes 4-? and 4S, electrically connected with the rings 39 and i0, which brushes c011- tact with the copper commutator strips or segments 2i and 25. Secured to the end of the stud-shaft t2 is a stationary cam-dog 4.9, with which engage curved springs 50, secured to the disk 11, the tendency of which is to press toward the center of the disk. The object of this construction is to th row the brushes 4? and 48 across the spaces between the edges of the commutator strips or segments in shifting the poles of the pistons. The dog also acts as a washer to hold the disk in place.
For the purpose of diminishing the spark caused by the current being broken as the brushes cross the spaces between the commutator-strips I provide a governor (see Fig. 5) comprising a base 50, of insulating material, upon which is mounted a solenoid 5], one terminal of which is connected with the negative wire of the dynamo, while the other is connected with a rheostat 52, of any ordinary or suitable construction. The other terminal of the rheostat is connected with the positive wire of the dynamo. The upper end of the core 53 of the solenoid at its upperend is pivoted to the lever 5-1, fulcrumed at 50 to a standard 57, secured to the base. The oppositc or free end of this lever is provided with two brushes 58 and 59, which slide on the contacts of the rheostat. Between the end of the lever and its fulcrum is a coiled spring 60, secured to said base and lever, of sufficient power to counteract the weight of the core when the solenoid is slmrt-circuited and cause thebrushes to slide down the coir taets of the rhcostat, thereby reducing the current fed to the cylinders and pistons.
In order to prevent water from accumulating in the horn 27 through leakage from the stuffing-box, the enlarged inner end is provided at the lower side with a pipe 01, having a check-valve 62, and opposite thereto with a pipe 63, having oppositely-working check-valve 6t. \Vhen the pistontube is drawn into the cylinder, air will be sucked into the horn through pipe 63, and 011 the return stroke it will force the air and water out through pipe 61 and thus keep the horn dry. The horn does not cont-act with the reciprocating piston-tube, but serves to protect the same from injury and from water.
All the coils are intended to be provided with a brass easing surrounding the same, with a filling of resin or other suitable material, so that the pump can be submerged without liability of the entrance of water.
The operation is as follows: An electric en 1:- rent being passed through the coils of the cylinders and pistons, the cylinders and pistons will be converted into electromagncts. The coils of the cylinders are so wound with respect to each other that their opposite poles will be in reverse directions, and when the north pole of cylinder 1 and the south pole of its piston are opposite to each other the north pole of the other cylinder will be opposite the north pole of its piston. As the piston in cylinder 1 is drawn to the north end of the cylinder by the mutual attraction therebetween and reaches the end of its stroke, the poles of the pistons will be reversed by the shifting mechanism, when the north pole of cylinder 2 and the south pole of its piston will be opposite each other, and the piston being attracted thereto will cause the return stroke. The operation will thus continue, the poles of the pistons being alternately shifted, so as to keep up a constant reciprocation of the pistons.
The pole-shifting mechanism operates as follows: Supposing the piston to be in the position shown in Fig. 1, with the north pole at the left of cylinder 1, opposite the south pole of its piston, the latter will be attracted to said end, carrying with it the other piston with which it is connected, the circuit being as follows: from dynamo to the cylinder-coils and then back to dynamo, and from positive dynamo to the horn, to the tube 34, to one of the binding-posts, near the inner end thereof, to the brushes and conducting-ring 37 and 39, to brush 47, to commutator strip or segment 24, to the coils of the piston, thence by wire 18 to piston-coils in cylinder 2, to wire 19, commutator-segments 25, brush 48, conducting-ring 37, to brush 38, to the other binding post or tube 34, to negative wire of dynamo. As the pistons reach the end of their stroke the pins 46 will strike the outer curved edges of the cams 43, rotating the same and the disk 41, to which they are secured, and forcing the springs 50, secured to the disk, outward by means of the stationary dog 49. YVhen the brushes 47 and 48 pass off of the commutator-segments, the resiliency of the springs will rotate the disk still further, throwing the brush esacross the break or space into contact with the other commutator-segments, reversing the current and shifting the poles of the pistons, so that the north poles of the cylinder 2 and its piston will be opposite to each other, and the piston in the said cylinder 2 will be attracted to the right, causing the return stroke of the pistons. This operation will be alternately repeated, causing a constant reciprocation of theepistons.
Having thus described my invention, what I claim is 1.
