PHOEBE A. GREEN AND ANDREW W'. GREEN, OF TORONTO, ONTARIO', CANADA; SAID PHOEBE A. GIR-EEN ASSIGNOR TO SAID ANDREW' W. GREEN.

FLOOR WAXING AND POLISI-YIING APPARATUS.

To all whom it may concern:

Be it known that we, PHOEBE A. `GREEN and ANDREW W. GREEN, both of the city ot Toronto, in the county of York, Province v of Gntario, Canada, subjects of the King of Great Britain, have invented `certain new and useful improvements in Floor Waxing and Polishing Apparatus, of which the .following is a specification.

This invention relates to loor waxing and polishing apparatus and more particularly to that type in which a plurality of Hoor iinishing tools including a brush and a waxer pad are rotatably and interchangei' ably carried on a .carriage and rotated by an electric motor and our .object `is to, provide means for limiting the spread of the bristles of the brush; another Object is to construct the apparatusv so that it is better adapted to brush an uneven floor, a further object being to tconstruct a wax carrying pad so that lateral movement oi' the wax due to centrifugal4 action yis limited. A still further object is to provide means for vertically adjusting the carriage vrelative to the floor so that the desired pressure may beapplied to the finishing tools.

yWe vattain our objectsl by means 'of the constructions `hereinafter, described, and illustrated in the accompanying drawings in which Fig. 1 is a vertical section of our carriage showing the finishing tools in elevation;

Fig. 2 a horizontal section of the `car-` riage;

Fig. 3 a vert'cal section of the brush finishing tool; 4

Fig. 4L a vertical section of the waxing linishing tool;

Fig. 5 a plan view ot the underside of the waxing tool, partly broken away; and

6 a sectional detail of the gliders.

1 is a carriage having depending sides and ends, the ends being provided with gliders 45 2 as hereinafter described. At the sides of the carriage substantially midway between the ends thereof are carried the vertically adjustable vwheels 3. These wheels are journalled on slides A which are mounted in the @c guides 5 secured at the inner opposite sides of the carriage. Any suitable means such as set screws 6 may be employed to hold the slides as adjusted so that the carriage may be balanced and run on the wheels, the

gliders only being used yto prevent thekdeing "the pulleys 9 and 30 secured to their f lower ends. At the upper ends oi' the spindles are secured, by ymeans of pins, the collars 10 to prevent longitudinal movement ot the spindles. These pulleys and spindles are driven lby a motor 34 as hereinafter described/ On the pulleys 9 and 30 are interchangeably carried the iioor finishing tools which include a brush 10 and a waxing pad 11.

To polish floors having an uneven surface the machines now on the market depend entirely on the flexibility of the brush bristles. Vhen va brush having flexible bristles is rotated by a motor the bristles spread outwardly until they lie against the back of the brush and thus lose their flexibility. To overcome this objectionable feature and to provide means for carrying the brush so. that it will polish an .irregular floor we carry thebrush in an inverted cup shaped carrier 12 (see Fig. 8). The lower end oi' the rim 13 or this carrier engages the bristles of they brush to limit their outward spread and this lower ,end is preferably flared outwardly to prevent the rim cutting the bristles. e

The brush is `loosely received inside the rim ,13 and is driven by means of the laterally extending pins 14 secured to the brush7 which pins pass/through vertical slots 15 formed in the rim 'wherebythebrushwill be permitted to rock relative to its carrier,

so that it will adjust itself to'polish an uneven or irregular floor. The brush carrier 12 is detachably connected with the pulley-9 in the following manner. A disk 31 suitably secured to the lower side of thepulley is provided with keyhole slots 16 adapted to receive the keysr 17 formed integral with the disk 18 securedv to the carrier 12. To position the keys 17 relative to their slots 16 a ystud 19 concentrically carried on the carrier is adapted to be received in the lower end ot the tubular spindle 8. This stud passes through holes formed in the carrier and its disk and is provided intermediate its ends with a shoulder 20 adapted to engage the underside ot the carrier, the stud being held in position by means of a nut engaging the upper side of the disk. The brush 10 is provided with a concentric tapered hole through which the lower end 0f the Stud 19 passes to centrally locate the brush relative to its carrier 12. A coil spring 22 having one end secured between the shoulder 2() and the carrier and the other end engaging the top of the brush 1() yieldingly holds the latter in engagement with the floor.

The waxing pad 11 is carried on a carrier 12a having a depending rim 13'FL on which a wax receptacle 23 is detachably connected by means of the bayonet joints 24, see Fig. 4. This wax receptacle is formed with an open bottom below which is suitably carried the perforated cover 32 of leather or other flexible material. The carrier 12 is provided with a disk 18 having the keys 1'7 for detachably connecting the carrier with the pulley 30 in the same manner as the carrier 12 is connected with its pulley 9.

lVhen the wax is placed in a rotatable waxing pad driven by a motor the wax is thrown against the inner peripheral sides of the receptacle due to centrifugal force and the wax passes over the centrally located holes of the pad without passing through them so that the holes near the periphery of the pad are the only ones through which the wax passes. This construction also causes the wax to spread in a lateral direction away from the floor finishing apparatus. To limit the` movement of the wax due to centrifugal force and to utilize all the perforations in the cover 32 for the passage of wax therethrough and thus prevent. the wax spreading laterally of the waxing device we provide the following means. 1t will be noted that the perforations formed in the cover 32 are arranged in a plurality of spaced series which are substantially concentrically arranged. In the receptacle 23 is fitted a disk 25 having a plurality of rings 26 secured in any suitable manner to the underside of the disk and arranged concentrically thereof. These rings extend downwardly from the disk and their lower edges are adapted to engage the upper side of the cover 32 to limit the lateral movement of the waX inside the receptacle. The rings are spaced apart so that each ring will be substantially in alinement with the outer edges of the perforations in a series so that all the perforations will be utilized for the passage of waX.

The waxing device is used by detaching the receptacle 23 from its carrier 12 and then removing the disk 25 with its rings 2o from the receptacle. Tax is then lled in on the underside of the disk between the rings 26 and the disk is replaced in the receptacle so that the rings rest on the cover 32. The rings thus form separate annular iompartments for the wax. Preferably the rings 26 are of frusto conical form to tend to force the waX through the perforations in the cover 32. Vhen the receptacle is connected by the carrier 12a the lower end of a stud 19Z1 carried by the carrier 122L engages a resilient cushion 33 fitted within the receptacle on top of the disk 25 and limits the upward movement of these parts.

The motor 34 secured to the upper side of the carriage is provided with a depending spindle on which are secured the pulley 27 and 28, the pulleys being connected by means of endless belts with the pulleys 9 and 30 respectively.

Referring to F ig. 1, it will be noted that the pulleys 27 and 28 are arranged one below the other which necessitates suitable means for taking up the distance between the centres of these pulleys. This is accomplished by securing a distance collar 29 to the underside of the pulley 30 and to this distance collar 29 is secured the disk 31 in which the keyhole slots 16 are formed. YVith this arrangement the disks 31 on the pulleys 30 and 9 are substantially in horizontal alinement whereby dierent tools of the same height may be attached thereto.

1t will be noted that the bearings 7 are offset longitudinally of the apparatus, (see Fig. 2) so that when two similar finishing tools are being used a greater width of floor will be finished than the width of one of the finishing tools without increasing the resistance of each tool.

To vertically adjust the gliders 2 relative to the carriage and thus vary the pressure on the floor finishing tools we provide the following means. Adjacent the lower edges of the depending ends of the. carriage are formed holes through which the screws 35 are passed. These screws also pass through suitable notches formed in the upper ends of the gliders 2. The gliders are clamped as adjusted against the depending ends, by means of the metal strips or clamping members 3G in which are threaded the screws 35. Preferably each glider is formed by doubling a strip of felt or rubber on itself and cutting the notch or notches in the free ends thereof. These notches are cut sufliciently deep to permit the strips 36 to clamp the gliders when the latter are lowered relative to the screws 35.
