2,702,395 Patented. Feb. 22,, 1955,
Referring-to thedrawings, the -numeral 1. designates the=- apparatus as a whole. As here illustrated the'machine-comprises-a casing having a base or bottom portion'2' which may be an integral metallic casting, for exampleof aluminum, or which may be molded from other material, for instance a suitable synthetic resin,
this base; as here illustrated, being cup-like in shapeand designed to constitute a support'for the-electric motor (not shown) andto provide a bearing for the normally vertical shaft'or spindle which carries the polishing or scouring element. As illustrated, the casing alsocomprises an upper part 3, here shown as of inverted, cuplike shape, desirably of thin sheet metal or the like, andhaving openings for ventilating the motor. Preferably at gasket 4 of resilient or sound deadening material is interposed'betweenthe lower edge of the part 3 and thebase 2'. The severahpartsof the casing are united in any appropriate manner, for example by bolts or screws. The-motor is suppliedwith current througha flexible conductor 5. The motor may be-arranged with'its shaft coaxialwiththe axis of the casing, the shaft then extend-- ing down through the bearing in the lower part of the base 2 and forming the immediate support for the disk which carries the polishingand scouring elements. Under such-.circumstancesthe spindle or shaft is driven at the motor speed. However, it is preferred to interpose; speed reduction gearing (not shown) between the motor and the spindle or shaft 6' to which the polishing disk is. securediin order that the speed of rotation of the polish-- ing diskmay be less than that of the motor, thus avoiding the-possibility-of overheating the work during'the scouring'or polishing operation. The lower end of the spindle or shaft 6 (Fig. 2.) is provided, as is usual in such machines, with an axial, screw threaded bore designed to receivea screwthreaded axial boss '7 (Fig. 3) at the upper end ofthestemfiiofthe disk-9:011 which the scouring or polishing element is mounted. As illustratedin Fig. 1- a thick. polishing pad 10 of soft material such as felt or wool is mountedin the disk 9.
As herein illustrated, the base 2 is provided with an integral: outstanding lateral boss 11. This boss has a vertical outer surface 12 and a second vertical surface or shoulder 13; A handle-element 14,- here shown as a hollow-hand grip properly-designed and shaped to be grasped in the hand of'the user, is connected to the boss. 11 for use in manipulating the apparatus when operating upon elevated objects (ascontrasted with. use orrthefloor); As illustrated, this hand grip'member I4. is: made from: stiff" sheet metal and at its inner end'isprovided withspaced, parallelears 15 and 16 (Fig; 4*) which aredesigned toreceive the boss 11 between them, these ears15 and lfi beingprovided with aligned open-v ings for thereception of a bolt 17 which passes throughtheseopenings and throughan opening inthe boss 11 andwhich is provided with awing, nut 18 by means of whichithe parts may betightened so as to hold the handigrip 14 ina' desired" position of adjustment. The; surfaces.- 12" and 13 of. the boss form limiting; elemente for thehand gripand together with the bolt 17 constitute a knuckle joint permitting; the hand; grip to; beswung-from the horizontal position of Fig. 2' (wherein a shoulder-19 (Fig. l) ofthe hand grip contacts; the surface 12 of the boss 11?) to; aposition wherein another shoulder 20 (-Fig. 1) of thehan'dgrip contacts the vertical surface 13 of the boss 11. As illustrated, this permits an arc of movement of approximately 45, although by varying the positions of the shoulders 19 and 20 such are of movement might be varied, if desired.
The flexible conductor 5 enters the interior of the hand grip 14 through an aperture defined by an insulating collar 21 (Fig. 5) and passes down inside of the hand grip and emerges near the inner or pivoted end of the hand grip through an opening defined by another insulating collar 22. A bight 5 of the flexible conductor permits freedom of movement of the handle, the conductor entering the base 2 of the casing through a third insulating collar 23.
A rigid web member 24 formed from the material of the hand grip extends across the outer end of the latter (Fig. 5) and as here illustrated is shaped to provide an integral, inwardly directed annular flange 25 which is internally screw threaded.
In accordance with the present invention there is provided an extension handle comprising a rod 26 (Fig. which may, for example, beof wood or if preferred, 'of tubular metal, here shown as of wood and having a metallic ferrule 27 at one end, the ferrule having a screw threaded axial stud 28 designed to engage the screw threads within the annular flange 25 so as rigidly but removably to unite the rod 26 to the hand grip 14. The rod 26 may be of any desired length and may be long enough so that a single length of rod is sufiicient for use in propelling the machine along the floor while the operator is in standing position. However, for convenience in shipping and storage it is preferred to employ a sectional extension handle comprising the rod 26 and one or more additional lengths of rod, for example, 26'- (Fig. 6). As shown in Fig. 6 the rod 26 is provided at its outer end with a ferrule 28 designed to receive the end of the second section 26 If desired these parts may have screw threaded engagement, although ordinarily it will sufiice merely .to slip the end of the rod section 26 into the plain ferrule 28. While the extension handle is here shown as comprising two sections 26 and 26 it is contemplated that a greater number of sections may be employed if desired.
In using the device and assuming'that it is to be used for working on elevated objects such as furniture or the like, the hand grip 14 will usually be arranged in the position shown in Fig. 2. The parts may thus be arranged by loosening the Wing nut 18 and swinging the grip member 14 down until the shoulder 19 engages the surface 12. The wing nut is then tightened to retain the parts in this position. The disk 9 is then connected to the spindle or shaft 6 and the appropriate working element, for example a sand paper disk or a polishing pad, is secured to the disk 9. The operator then grasps the handle 14 and having started the motor, moves the apparatus about the work as desired, supporting as much of the weight of the machine as is desirable by his grip on the handle 14. If the horizontal position of the handle 14, as shown in Fig. 2, is not convenient for the particular work at hand, the grip member 14 may be swung upwardly, more or less, by loosening the wing nut 18 and after adiusting it to the desired position, again tightening the wing nut.
If it be desired to use the apparatus for sanding or polishing a floor, the extension handle is attached to the end of the hand grip 14, as shown in full lines in Fig. 6, the screw threaded boss 28 at the end of the rod 26 being screwed into the flange 25 at the end of the hand grip, and the additional extension section being then assembled with the rod 26. The operator will then loosen the wing nut 18 and swing the extension handle means to the most convenient position for use in'propelling the apparatus along the floor. Usually thebes't position is that in which the shoulder 20 engages the vertical surface 13 of the boss 11 for in this position it is possible to apply a substantial downward thrust to produce the desired pressure of the working element upon the floor. However, the operator may set the handle means at various positions, as indicated in broken lines in Fig. 6, and if desired may fix the handle in the selected position by tightening the wing nut 18.
While it is most convenient to provide the extension handle by connecting the sectional rod to the end of the hand grip 14 it is contemplated as within the scope of the invention to provide the base 2 of the casewith a.
socket independent of the hand grip member 14 into -which the screw threaded boss 28, at the end of the rod 26, may be inserted, as well as such equivalent means of connecting the extension handle as may be found most convenient and desirable. It is further to be understood that while a desirable construction has herein been suggested by way of example, the invention is broadly inclusive of any and all equivalent arrangements whereby the apparatus is made convenient for alternative use in working on the floor or in working on articles or objects elevated from the floor.
