Abstract
A floor cleaner motor mount wherein the motor is resiliently pivoted to provide the desired disposition of the belt in a cog drive belt extending between the motor and a rotatable brush of the cleaner located in a nozzle portion of the cleaner. The pivot axis is disposed so as to permit the axis of the motor shaft to be angularly adjusted relative to the axis of the brush. The pivot may be provided at one end of the motor housing. In the illustrated embodiment, the motor is adjustably positioned by a leaf spring acting against a base portion of the nozzle housing intermediate the pivot and drive connection.
Claims15
In a floor cleaner having a brush and means for supporting the brush for rotation about a brush axis, the improvement comprising:
- an electric motor having a housing and a drive shaft defining a drive shaft axis;
- drive means for rotating the brush as an incident of rotation of the motor drive shaft;
- means for mounting the motor to pivot about a pivot axis extending transversely of said drive shaft axis and resultingly dispose said motor shaft angularly relative to said brush axis;
- and
- means for adjustably pivoting the motor about said pivot axis.
In a floor cleaner having a brush and means for supporting the brush for rotation about a brush axis, the improvement comprising:
- an electric motor having a housing defining an end flange, and a drive shaft defining an axis generally parallel to said brush axis;
- belt drive means extending between said shaft and brush for rotating the brush as an incident of rotation of the motor drive shaft;
- means for mounting the motor to pivot about a pivot axis spaced from said end flange;
- spring means for adjustably pivoting the motor about said pivot axis to properly position said belt drive means;
- and
- a retainer carried by the housing defining an opening opening transversely to said drive shaft axis and movably receiving said end flange to permit limited pivotal and axial displacement of the motor thereby to retain the motor with the belt drive properly positioned.
In a floor cleaner having a brush and means for supporting the brush for rotation about a brush axis, the improvement comprising:
- an electric motor having a housing and a drive shaft;
- belt drive means extending between said shaft and brush for rotating the brush as an incident of rotation of the motor driven shaft;
- means for mounting the motor to pivot about a pivot axis;
- and
- spring means for adjustably pivoting the motor about said pivot axis to properly position said belt drive means, said mounting means comprising means for mounting the motor to pivot about an axis at one end of the motor.
In a floor cleaner having a brush and means for supporting the brush for rotation about a brush axis, the improvement comprising:
- an electric motor having a housing and a drive shaft;
- belt drive means extending between said shaft and brush for rotating the brush as an incident of rotation of the motor drive shaft;
- means for mounting the motor to pivot about a pivot axis;
- and
- spring means for adjustably pivoting the motor about said pivot axis to properly position said belt drive means, said cleaner including a nozzle housing having a pivot portion engaged by one end of said motor and defining said pivot axis.
In a floor cleaner having a brush and means for supporting the brush for rotation about a brush axis, the improvement comprising:
- an electric motor having a housing and a drive shaft;
- belt drive means extending between said shaft and brush for rotating the brush as an incident of rotation of the motor drive shaft;
- means for mounting the motor to pivot about a pivot axis;
- and
- spring means for adjustably pivoting the motor about said pivot axis to properly position said belt drive means, said cleaner including a nozzle housing having a mounting portion removably engaged by said spring means for positioning said spring means in biasing engagement with said motor housing, said spring means comprising a leaf spring and said mounting portion defining means for releasably retaining one end of the leaf spring.
