Abstract
A jack is adapted for both lifting and pumping functions driven by a common drive motor. This jack has a detachable motor/air pump unit for use apart from the remainder of the jack. The motor/air pump unit is formed as a single unit which, if desired, is independently supported by a stand which is integral therewith. The unit is operatively, removably received in a saddle of the jack, where it is secured in place by a pivoted strap and buckle arrangement.

In a hydraulic jack having a motor, a motor shaft driven by the motor, the motor shaft having at least one end extending from the motor, a pumping mechanism and a means for operatively securing the motor to the jack, the improvement thereupon being the said means comprised of:
- a saddle secured to the jack, the saddle having a recessed portion for receiving the motor therein;
- a strap having one end secured to the saddle and a second, opposite end secured to a portion of the saddle remote from the one end of the strap, such that when the motor is received in the recessed portion of the saddle, the strap extends over the motor securing the motor to the saddle;
- reduction gearing carried by the saddle, said reduction gearing being operatively connected to the pumping mechanism for driving said pumping mechanism, the reduction gearing being substantially aligned with the recessed portion, such that when the drive motor is received in the recessed portion of the body, the one end of the motor shaft is operatively connected to the reduction gearing, so that the reduction gearing is driven by the motor shaft.
In a hydraulic jack having a motor, a motor shaft driven by the motor, the motor shaft having at least one end extending from the motor, a pumping mechanism and a means for operatively securing the motor to the jack, the improvement thereupon being the said means comprised of:
- a saddle secured to the jack, the saddle having a recessed portion for receiving the motor therein;
- a strap having one end secured to the saddle and a second, opposite end secured to a portion of the saddle remote from the one end of the strap, such that when the motor is received in the recessed portion of the saddle, the strap extends over the motor securing the motor to the saddle;
- reduction gearing housing carried by the saddle, said housing having reduction gearing disposed therein;
- the reduction gearing being operatively connected to the pumping mechanism for driving said pumping mechanism, the reduction gearing being substantially aligned with the recessed portion, such that when the drive motor is received in the recessed portion of the body, the one end of the motor shaft is operatively connected to the reduction gearing, so that the reduction gearing is driven by the motor shaft;
- and
- the motor shaft being operatively coupled with the reduction gearing by a recessed translational shaft having one end thereof secured to the reduction gearing and a second opposite end thereof having a recess formed therein to removably receive in said recess, the other end of the motor shaft, said translational shaft being journaled in bearings and being disposed in the reduction gearing housing.
In a hydraulic jack having a motor, a motor shaft driven by the motor, the motor shaft having at least one end extending from the motor, a pumping mechanism and a means for operatively securing the motor to the jack, the improvement thereupon being the said means comprised of:
- a saddle secured to the jack, the saddle having a recessed portion for receiving the motor therein;
- and
- a pivoted strap having a one end pivotably secured to the saddle and further having a second opposite end being removably secured to the saddle portion, such that when the drive motor is removably received in the saddle, the strap extends over the drive motor when the second opposite end of said strap is secured to the housing, removably supporting and securing the drive motor therein;
- reduction gearing housing carried by the saddle, said housing having reduction gearing disposed therein;
- and
- reduction gearing being operatively connected to the pumping mechanism for driving said pumping mechanism, the reduction gearing being substantially aligned with the recessed portion, such that when the drive motor is received in the recessed portion of the body, the one end of the motor shaft is operatively connected to the reduction gearing, so that the reduction gearing is driven by the motor shaft.
In a hydraulic jack having a motor, a motor shaft driven by the motor, the motor shaft having at least one end extending from the motor, a pumping mechanism and a means for operatively securing the motor to the jack, the improvement thereupon being the said means comprised of:
- a saddle secured to the jack, the saddle having a recessed portion for receiving the motor therein;
- a pivoted strap having a one end pivotably secured to the saddle and further having a second opposite end being removably secured to the saddle portion, such that when the drive motor is removably received in the saddle, the strap extends over the drive motor when the second opposite end of said strap is secured to the housing, removably supporting and securing the drive motor therein;
- reduction gearing housing carried by the saddle, said housing having reduction gearing disposed therein;
- reduction gearing being operatively connected to the pumping mechanism for driving said pumping mechanism, the reduction gearing being substantially aligned with the recessed portion, such that when the drive motor is received in the recessed portion of the body, the one end of the motor shaft is operatively connected to the reduction gearing, so that the reduction gearing is driven by the motor shaft;
- and
- the motor shaft being operatively coupled with the reduction gearing by a recessed translational shaft having one end thereof secured to the reduction gearing, so that the reduction gearing is driven by the motor shaft;
- and
- the motor shaft being operatively coupled with the reduction gearing by a recessed translational shaft having one end thereof secured to the reduction gearing and a second opposite end thereof having a recess formed therein to removably receive in said recess, the other end of the motor shaft, said translational shaft being journaled in bearings and being disposed in the reduction gearing housing.
