Portable, self-contained, electrical pumping device

Claim 1

A PORTABLE PUMPING DEVICE FOR PUMPING FLUIDS COMPRISING, A SMALL COMPACT PORTABLE HOUSING HAVING AN ACCESS OPENING THEREIN AND HAVING A CLOSURE MEMBER FOR CLOSING SAID OPENING, A RESERVOIR STRUCTURE MOUNTED WITHIN SAID HOUSING FOR STORING A QUANTITY OF FLUID THEREIN, A CYLINDER MOUNTED IN SAID HOUSING AND CONNECTED IN COMMUNICATING RELATION WITH SAID RESERVOIR STRUCTURE FOR RECEIVING FLUID THEREFROM, RECIPROCABLE MEANS SHIFTABLE IN SAID CYLINDER FOR FORCING FLUID THEREFROM COMPRISING A SOELNOID INCLUDING AN ELECTROMAGNET, A MAGNETIC ARMATURE DEFINING A PISTON AND EXTENSIBLE IN THE CYLINDER UNDER THE INFLUENCE OF THE ELECTROMAGNETIC FIELD OF SAID ELECTROMAGNET THROUGH A FORWARD STORKE TO FORCE FLUID FROM SAID CYLINDER, SPRING MEANS ENGAGING SAID ARMATURE FOR RETRACTING THE SAME THROUGH A RETURN STROKE WHEN THE ELECTROMAGNET IS DE-ENERGIZED, A NORMALLY OPEN POWER CIRCUIT CONNECTED TO SAID ELECTROMAGNET TO CONTROL THE ELECTROMAGNETIC FIELD THEREOF AND CONNECTED TO A SOURCE OF ELECTRICAL CURRENT, A NORMALLY OPEN CONTROL CIRCUIT INTERPOSED IN CIRCUIT CONTROLLING RELATION WITH SAID POWER CIRCUIT AND CONNECTED TO SAID SOURCE OF ELECTRIC POWER AND INCLUDING A NORMALLY OPEN PRIMARY SWITCH WHICH IS ENERGIZED AND CLOSED WHEN SAID MANUAL SWITCH IS CLOSED TO ENERGIZE SAID POWER CIRCUIT AND THE ELECTROMAGNET, A SECONDARY SWITCH MEANS IN SAID CONTROL CIRCUIT BEING OPENED AND CLOSED IN RESPONSE TO MOVEMENT OF SAID ARMATURE AND HAVING A SWITCH ARM, WHEREBY WHEN SAID MANUAL SWITCH IS CLOSED, SAID CONTROL AND POWER CIRCUITS ARE OPERABLE TO CAUSE UNINTERRUPTED FLOW OF INTERMITTENT ELECTRICAL CURRENT TO SAID ELECTROMAGNET TO RECIPROCATE THE ARMATURE AND PERMIT FLUID TO BE CONTINUOUSLY PUMPED FROM SAID CYLINDER, SAID ELECTRICAL CURRENT CONTINUING TO FLOW THROUGH THE POWER CIRCUIT WHEN SAID CONTROL CIRCUIT IS ENERGIZED AND SAID PRIMARY SWITCH IS IN THE CLOSED CONDITION, A POSITION HOLDER SWITCH MECHANISM IN SAID CONTROL CIRCUIT OPERABLE TO HOLD SAID SECONDARY SWITCH MEANS IN ONE OF SAID CLOSED AND OPENED POSITIONS DURING MOVEMENT OF SAID ARMATURE UNTIL THE ARMATURE HAS COMPLETED ITS RETURN OR FORWARD STROKE, AN ACTUATING MEANS COMPRISING AN ANNULAR YOKE ELEMENT ON SAID ARMATURE AND MOVABLE THEREWITH, SAID YOKE ELEMENT CIRCUMSCRIBING THE SWITCH ARM OF SAID SECONDARY SWITCH MEANS AND ENGAGING THE SAME TO THEREBY CAUSE OPENING AND CLOSING SAID SECONDARY SWITCH DURING MOVEMENT OF SAID ARMATURE.
