Application "July'27, IMSgSfial ram-semen 6 .Claims (Clr15' r-491)" The present invention relates to the construe-.2
tion andoperation of floor maintenance machines,
and-rmore' particularly to machines. of. the char.-: acter. described comprising a motor driven, floor surfacing. element arranged to rotate about-a ver-r ticalaxis whenin use;
The rotary surfacing element-of such machines normally consists of a brush member having-an annular wooden base detachably securedin a'pre'a determined position to a rotary drive element and in:which base tufts of wire, hair or fiber are em-.
bedded inany suitable. manner." The :tufts are initiallypositioned and. trimmed to. provide a level:

The general object. of my invention is-the provision of a floor maintenance machine having an improved drive connection between the drive mechanism and rotary surfacing element which tends to keep torque stresses on. the drive mecha nism due to uneven. brushing. or 'fioor. surfaces. ata minimum and thus provide a long. lifefo'r. both; the rotary surfacing I element and drive mechanism. A further and more specific object is. the provision ofan improvedform'ofconnecting. bracket which provides a selfeleveling detachable. drive connection between the rotary surfacing.

the adjacent lug face 43*, a relatively stiff flat spring 46 is secured at one end to the underside of the bracket adjacent the corresponding recess with its free end downwardly bent away from the bracket into a substantially horizontal plane and terminating adjacent the lug face 43*. At symmetrically spaced points on the periphery of the lower shell section 23 corresponding to the location of the recesses 45, short integral lugs 41 of substantially rectangular cross-section and a shape permitting passage through the recesses 45, project from the shell with their upper urfaces at a level corresponding to the level of the plane of the fiat springs 46.
With the described construction, the brush member 30 is readily mounted in the machine by tilting the machine and positioning the bracket electric motor, a horizontally arranged rotary surfacing element, and means forming a drive connection between said motor and said rotary surfacing element including a vertical drive shaft driven by said motor, a rotary shell surrounding and driven by said shaft, a plurality of symmetrically arranged peripheral drive lugs projecting from said shell, a bracket mounted on said rotary surfacing element and having recesses therein adapted to receive said drive lugs, spring means on the underside of said bracket at positions angularly adjacent said recesses and arranged to recesses 45 so as to pass over the lugs 41 and then angularly moving the brush member counter to the designed direction of brush rotation until the a lugs 41 pass under and in resilient contact with the springs 46 until they abut the faces 43 of the corresponding stop members 43. In this position, the upper surface of the bracket will be in contact with the peripheral flange on the shell section 23 and the springs 46 will exert a downward pressure on the drive lugs 41. In detaching the brush member, the operation is reversed.
With the described drive connection between the motor 15 and the brush member 30, a positive drive is effected, while at the same time the resilient support of the brush member on the drive lugs 41 permits a limited movement of the brush member vertically relative to the shell 2| without disrupting the drive connection. This capacity for limited relative vertical movement between these parts allows the brush member to effect the desired surfacing action on rough or uneven floor surfaces without whipping and hopping. The resilient vertical contact of the parts tends to maintain the brushing surface in the same plane for all normal variations in tuft wear. Torque stress is kept to a minimum, insuring a long life to both the brush member and machine.
1 While in accordance with the provisions of the statutes I have illustrated and described herein the best form of the invention now known to me, those skilled in the art will understand that changes may be made in the form of the apparatus disclosed without departing from the spirit of the invention covered by my claims, and that certain features of my invention may sometimes be used to advantage without a corresponding use of other features.
