ity of devices of that type to which the inven tion appertains.
With the above and other objects in view, which will appear as the description proceeds. the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed. without departing from the spirit of the invention.
In the accompanying drawings Figure 1 shows in elevation, a device constructed in accordance with the invention;
Figure 2 is a longitudinal sectional. View wherein parts are omitted.
The pump forming the subject matter of this application includes a barrel 1. preferably made of non-magnetic material. Heads 2 and 3 are secured to the ends of the barrel 1. An outlet pipe 1 communicates with the barrel 1 through the head 3. An outlet pipe 5 communicates with the opposite end of the barrel 1. through the head 2. There are check valves 6 in the outlet pipes 4 and 5. The check valves 6 close toward the barrel 1. An inlet pipe '1' communicates withfhe barrel 1 through thehead 3. An'inlet pipe 8 cornmunicates with the opposite end of the barrel 1 through the head 2. There are check valves 9 in the pipes T and S. The check valves 9 close away from the barrel 1.
The pump above described may be mounted on a suitable foundation 3? of any desired sort. The pump may be used for any purpose desired. In one application of the invention, the pump is used in connection with a refrigerating coil 10 in which is interposed an expansion valve 11. One end of the refrigeratin'g coil 10 is designated by the nu meral 12, and the opposite end of the refrigerating coil is designated by the numeral 0 14. The outlet pipes 4 and 5 are connected to the end 12 of the coil 10, and the inlet pipes 7 anitll 180 are connected to the end 14 of the co A piston 15 is mounted for reciprocation 55 v in the barrel 1 and is made of such metal that it will act as the reciprocating core of an electromagnet. If desired, but notof necessity, the piston 15 may be surrounded at its ends with packing rings 16. Around the barrel 1 6 are placed the coils 17 and 18 of two solenoid magnets, tolwhich the piston 15, acting as a core, is responsive.
A switch mechanism is provided, and may include a standard 19 mounted on the barrel is 1 between the coils 17 and 18. Switch points 20 and 21 are mounted on the standard 19. The numeral 22 designates a switch operating member in the form of a lever adapted to engage the switch points 20 and 21, one at a 76 time. The switch lever 22 is fulcrumed intermediately, at 23. on the standard 19. One end of the switch lever 22 "passes through a. longitudinal slot 24 in the 'barrel 1, and into a longitudinal slot 25 which is formed in the #5 piston or core 15. The slot 25 defines shoulders 26 and 27 in the piston 15, the end of the switch lever 22 cooperating with theshoulders 26 and 27 in a way to be described hereinafter.
The switch. lever 22 issupplied intermediately with a transverse slot 28 through which extends a projection 29 on the standard 19. A retractile spring 30 is connected at one end to the projection 29, the oppo- 85 site end of the'spring being connected to the lever 22; the result being a snap switch construction which need not be dwelt upon in detail.
One end 31 ofthe coil 17 is connected to 00 the switch point 20. The opposite end 32 of the coil 17 is connected to one side of a battery 33 or other source of electrical energy. A conductor 34 is connected to the opposite side of the battery 33 and is connected to the switch lever 22. One end 35 of the coil 18 is connected to the switch point 21. The opposite end 36 of the coil 18 is connected to the conductor 32, and, therefore, to the battery 33.
When the parts are as shown in Figure 2, there is established a circuit including the battery 33, the conductor 32, the coil 17, the conductor 31, the switch point 20, the switch lever 22, the conductor 34, and the battery 33. The coil 17 now is energized, and the piston or core 15 moves to the left, responsive to the coil 17. The shoulder 26 ultimately engages the end of the switch lever 22 and, aided by the spring 30, tilts the switch lever 22 on its fulcrum 23 until the switch lever is out of contact with the switch point 20 and is in contact with the switch point21. The circuit above described, is opened, and there is established another circuit including the battery 33, the conductor 36, the coil 18, the conductor 35, the switch point 21, the switch lever 22, the conductor 34 and the battery 33.
The coil 18 now is energized, and the core or piston 15 is moved into the position shown in Figure 2, the shoulder 27 tilting the lever 22 off the switch point 21 and upon the switch point 20, to repeat the cycle.
When the piston 15 moves to the right, a liquid will be forced out through the pipe 7 and drawn in through the pipe 8. When the piston 15 moves to the left, the liquid will e drawn in through the pipe 6 and be forced out through the pipe 5. It will be obvious that when the pump is yoked up to the coil 10, a circulation will be maintained through the coil, although if the operator desires to use the pump in connection with somethin other than a refrigerating coil, he is at 1i erty to do so.
Having thus described the invention, what is claimed is A pump comprising a fixed standard, a barrel provided at each end with a conduit and having a longitudinal slot, solenoid magnets on the barrel and located on opposite sides of the slot, a combined piston and core mounted to reciprocate in the barrel and responsive to the magnets, the piston and.
core-having a longitudinal slot defining shoulders, and an operating member movable 'withrespect to the piston and core, the
movable operating member being a lever, means for fulcruming the lever on the standard, the movable operating member extending through the slot in the barrel and into the slot in the pistbn and core, the shoulders engaging the movable operating member as the piston reaches the ends of its strokes in ture.
