JOHN ROBERT CAMPBELL, OF REGINA, SASKATCHEWAIN, CANADA.

COMBINED FLQGR WAXEB; AND BOLISHER.

Appiication filed July 31, 1922. Serial. No. 578,722.

To (1U whom it may. concern: 1

lie it known that 1, JOHN Ronnn'r CAMP- BELL, a. subject of the King of Great Britain, a resident of the city ot Regina, in the Prov= incc ot Saskatchewan, Canada, have invented certain new and useful Improve ments in Combined Floor vi axers and P01- i.-:hers, of which the following is the specification.

lily invention relates to improvements in combined floor waxers and polishers and the object of the invention is to devise means for alternately driving the rotary waxing pad or a polishing brush from an electric motor, as the device is pushed along the floor. r

A further object is to devise means where by the pad and brush can be readily changed as occasion demands.

A still further object is to devise a simple and eii'ective means tor attaching the waxing pad to a drum.

My invention consists of a combined floor waxer and polisher constructed and arranged all hereinafter more particularly described and illustrated in the accompanying drawing in which:

Fig. 1 represents a perspective view of a device constructed according to my invention, showing the cover broken away to show the working parts.

Fig. 2 is a front view ot the device show iug the same broken away and the brush just being released.

1 19:. is a similar view to Figure 2 show ing the brush replaced by the pad.

Fig. 4: is an enlarged elevational detail of one end oi the drum carrying the waxing pad, showing the means for attaching the pad to the drum, and

Fig. 5 is a plan view of the waxing pad.

Like characters of reference indicate corresponding parts in the diflierent views.

1 is the cover of the device which is adapted to be provided with the bale 2 suitably hinged thereto, said bale 2 having the upwardly extending handle 3 connected therewith. The bottom of the cover 1 is prov ded with a framework composed of laterally extending bars l upon which is supported the motor 5 provided with the driving pulley 6. 7 are castors provided on the bottom of the cover 1 for supporting the device on the floor. 8 is the driven pulley mounted on the spindle 9 which extends through the bosses 10 in one side of the cover 1 and is j ournalled therein, said spindle, being held in position by means of the collar 11. The inner face of the driven pulley 8 is provided with a squared hole 12 adapted to receive the squared end 13 of the drum 14., or the brush 15, depending on whether the pad or brush is in use. The opposite side of the cover 1 is provided with the inwardly extending threaded stud 16 which has a reduced inner end 17 adapted to be inserted into a hole 18 in the opposite end of the drum or brush, the outer end of such stud being suitably enlarged and knurled. 19 are flanges on the ends of the pad drum provided with suitably disposed hooks 20 on which are hooked the loops 21 of the pad 22, which is adapted to extend around the pad drum 14. y

23 is a belt extending between the drive pulley (3 and the driven pulley 8.

24 are the leads from the motor 1 extending up through the cover 1 along the bale 2 and up the handle 3, being provided with the usual switch on the handle to control the operation of the motor, such switch not being shown as it is common to devices of this nature and vacuum cleaners.

The operation of my device is as follows:

When it is desired to wax the floor the wax is spread on the pad 22, where such wax is in the form of paste. It the wax is in liquid form the pad would be dipped into the same. The pad is then applied to the drum 1 1 in the manner shown in Figure 3, the loops 21 ot the outer and inner ends being looped over the corresponding hooks on the ends of the flanges 19. My device is now run over the floor, the motor being turned on and the floor thoroughly waxed. When this is done, by unscrewing the stud 16 by means of the enlarged knurled head, the inner ends 17 thereof will be disengaged from the hole 18 in the drum and such drum can be pulled longitudinally until the squared end 18 is released from the square hole 12 in the driven pulley, when such drum can be replaced by the'brush 15 which is placed in position by reversing the above mentioned operation. The floor is then polished with the brush. I1": an exceptionally goodsurtace wererequired a polishing pad could be used constructed in exactly the same manner as the waxing pad, but placed on the drum in a dry condition.

From the above description it will be seen that I have devised a simple and effective combined floor w'axer' and olisher in which the waxing means and polishing means will be readily interchangeable,

Further I have constructed a device in which the number of parts will be exceedingly small and in which the device can be constructed at a comparatively srnall cost.

What I claim as my invention is:

In a floor waxer and polisher, the combination with a rotatable drum, of a flat pad adapted to be rolled around the drum, loops at the corners of the pad, flanges on the ends "the inner and outer ends thereof hooked over the respective hooks.

JOHN ROBERT CAMPBELL.
