Claims
- 1. A motorized jack assemblage comprising a kit adapted to collaborate with a jack having gearing means for raising or lowering a vehicle, said jack having a hollow cylindrical housing mounted on a supporting base, and a load supporting shaft coaxially mounted in said housing and comprising means for raising and lowering said load supporting shaft in vertical relation to said housing; which kit comprises in combination:
- a supporting plate;
- a direct current motor;
- a cable comprising terminal means constructed to connect said motor in energy transfer relation to a source of power available in said vehicle;
- reduction gear linkage connected in driven relation to said motor;
- a drive shaft connected to be driven in rotation by said reduction gear linkage;
- mechanical coupling means connected to be detachably coupled in mating relation between said drive shaft and said jack whereby connection of said coupling through a socket in the base of said jack is constructed to actuate the gearing means in said jack to cause the load supporting shaft of said jack to be raised or lowered in said cylindrical housing in response to the direction of rotation of said shaft; and
- electrical switching means connected to said cable having positive, negative and neutral current flow positions when said cable is connected to a source of power, for controlling the operation of said motor in driving relation to said reduction gear linkage and said drive shaft to raise or lower or stop the motion of said load supporting shaft in said jack housing in accordance with the position of said switch.
- 2. A kit in accordance with claim 1 comprising a supporting plate, means for removably securing said motor and said reduction gear linkage to said supporting plate.
- 3. A kit in accordance with claim 2 wherein said supporting plate comprises means for securely accommodating the supporting base of said jack in secured detachable relation on said supporting plate.
- 4. A motorized jack assemblage comprising a kit adapted to collaborate with a jack having gearing means for raising or lowering a vehicle, said jack having a hollow cylindrical housing mounted on a supporting base, and a load supporting shaft coaxially mounted in said housing and comprising means for raising and lowering said load supporting shaft in vertical relation to said housing; which kit comprises in combination:
- a supporting plate;
- a direct current motor;
- a cable comprising terminal means constructed to connect said motor in energy transfer relation to a source of power available in said vehicle;
- reduction gear linkage connected in driven relation to said motor;
- a drive shaft connected to be driven in rotation by said reduction gear linkage;
- mechanical coupling means connected to be detachably coupled in mating relation between said drive shaft and said jack whereby connection of said coupling through a socket in the base of said jack is constructed to actuate the gearing means in said jack to cause the load supporting shaft of said jack to be raised or lowered in said cylindrical housing in response to the direction of rotation of said shaft; and
- electrical switching means connected to said cable having positive, negative and neutral current flow positions when said cable is connected to a source of power, for controlling the operation of said motor in driving relation to said reduction gear linkage and said drive shaft to raise or lower or stop the motion of said load supporting shaft in said jack housing in accordance with the position of said switch;
- wherein said supporting plate comprises means for securely accommodating the supporting base of said jack in secured detachable relation on said supporting plate; and
- wherein said means for securely accommodating the supporting base of said jack comprises a pair of inwardly-directed U-shaped flanges disposed along opposite edges of said supporting plate for accommodating the supporting base of said jack in slidable relation to said supporting plate.
- 5. A kit in accordance with claim 2 which includes said jack as an element of said kit, said jack being permanently secured to the surface of said supporting base.
- 6. A kit in accordance with claim 2 wherein said source of power available in said vehicle is the battery of said vehicle.
- 7. A kit in accordance with claim 6 wherein said terminal means is constructed to plug into the power outlet for the cigarette lighter on the dashboard of said vehicle.
- 8. A kit in accordance with claim 3 wherein the weight of said motor, said reduction gear linkage, and said jack mounted in fixed relation on said support platform do not exceed about 20 pounds in weight.
- 9. A kit in accordance with claim 1 wherein the voltage of said source of power does not exceed about 24 volts.
- 10. A kit in accordance with claim 2 comprising an electric light in a housing hingedly secured to said supporting plate, whereby said electric light in said housing is disposed to be rotated to a position for directing a beam upward.
- 11. A kit in accordance with claim 2 comprising clamping means secured to said supporting plate; and a battery operated signal light detachably secured in said clamping means.
- 12. A kit in accordance with claim 2 comprising an elongated handle; and
- means for detachably securing said handle to one end of said supporting plate.
- 13. A kit in accordance with claim 1 wherein said mechanical coupling means comprises a steel key having a head portion having a broad base portion which narrows to a restricted central portion from which an elongated member projects outwardly in symmetrical axial relation to said central portion terminating in a key which is constructed to mate in secured relation through a socket in the base of said jack in driving relation to the gearing means of said jack.
