Claims

1. A RECIPROCATING STROKE MOTOR APPARATUS HAVING AT LEAST THREE SERIALLY-AXIALLY-ALIGNED ELECTRIC SOLENOIDS THAT SURROUND A COMMON HOLLOW CORE AND HAVING A MAGNETIZABLE PLUNGER POSITIONED WITHIN THE HOLLOW CORE AND MOVABLE THROUGHOUT THE LENGTH OF THE SOLENOIDS AND THAT OPERATES SOLELY ON ONE POTENTIAL SIDE OF A SOURCE OF ELECTRIC CURRENT TO ACCOMPLISH RECIPROCATING MOVEMENT OF THE PLUNGER WHICH COMPRISES, A MECHANICAL OUTPUT MEANS OPERATIVELY-CONNECTED TO SAID PLUNGER FOR MOVEMENT THEREWITH, FIRST SWITCH MEANS FOR THE ONE POTENTIAL SIDE THAT IS RESPONSIVE TO THE POSITION OF SAID MECHANICAL OUTPUT MEANS FOR SELECTIVELY CONTROLLING THE ELECTRICAL ENERGIZATION OF THE SOLENOIDS, SAID FIRST SWITCH MEANS HAVING A PLURALITY OF INDIVIDUAL ELECTRIC LEAD SWITCHES THAT ARE SERIALLY ARRANGED FOR SEQUENTIAL OPERATION BY SAID OUTPUT MEANS AS A FUNCTION OF ITS POSITION, SECOND SWITCH MEANS FOR THE ONE POTENTIAL SIDE THAT ELECTRICALLY-CONNECTS EACH OF THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS TO RESPECTIVE ONES OF SAID SOLENOIDS IN A SIMILARLY ORIENTED SEQUENCE WHEREBY SEQUENTIAL OPERATION OF THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS WILL BE ASSOCIATED WITH SEQUENTIAL POSITIONING OF THE PLUNGER WITHIN THE HOLLOW CORE, SAID SECOND SWITCH MEANS HAVING A PLURALITY OF ELECTRIC REVERSING SWITCHES ELECTRICALLY-CONNECTED BETWEEN THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS AND THE SOLENOIDS TO PROVIDE SELECTED ASSOCIATION OF THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS AND SAID SOLENOIDS WHEREBY AT LEAST TWO OF THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS CAN BE SELECTIVELY ELECTRICALLY-CONNECTED TO EACH ONE OF A PAIR OF ADJACENT SOLENOIDS, AND OPERATING MEANS MECHANICALLY-CONNECTING AT LEAST A PAIR OF THE REVERSING SWITCHES OF SAID SECOND SWITCH MEANS TOGETHER FOR SIMULTANEOUSLY MOVING THEM BETWEEN A FORWARD PLUNGER MOVEMENT INDUCING POSITION AND A BACKWARD PLUNGER MOVEMENT INDUCING POSITION.

3. A RECIPROCATING STROKE MOTOR APPARATUS AS DEFINED IN CLAIM 1 WHEREIN, THE LEAD SWITCHES OF SAID FIRST SWITCH MEANS INCLUDE FRONT AND BACK END SWITCHES;

A PAIR OF ELECTRIC ACTUATOR SOLENOIDS, ONE OF WHICH IS ELECTRICALLYCONNECTED WITH THE FRONT END SWITCH AND THE OTHER OF WHICH IS ELECTRICALLY-CONNECTED WITH THE BACK END SWITCH;

AND SAID ACTUATOR SOLENOIDS ARE MECHANICALLY-CONNECTED TO SAID OPERATING MEANS FOR MOVING IT AND THE REVERSING SWITCHES BETWEEN THE FORWARD AND BACKWARD PLUNGER MOVEMENT INDUCING POSITIONS.
