1o claims. (o1. ls-zssr;

The invention relates to polishersrand refers more particularly to polishers for floors and the like. One of the objects vof the invention is to so construct the polisher that a portion of its .fibrous member may beA heated to facilitate l spreading the wax over the oor or the like by the flbrousmember. Another object is to so construct the polisher that another portion of its fibrous member is at all times in condition to eect the polishing of thefloor or the like after the wax has been spread thereover. With these as well as other objects in view, the in- Vention resides in the novel features of construction and combinations and arrangements of parts as more' fully hereinafter set forth.

In the drawing: l Figure l isa side elevation, partly in section, of a polisher embodying our invention;

Figure 2 is an end elevation, partly in section, thereof; Figure 3 is a bottom plan view of the block and heating element. Y

The polisher embodying our invention is designed particularly for use in polishingoors or the like and has the body 1, which is encircled by the fibrous polishing member 2. A portion of this body and the adjacent portion of the fibrous member may be heated by the electrical heating element, whereby the surfacing material, such as wax, may be more easily spread over the door er the like.

The body 1 is preferably formed of the sheet metal cup-shaped base 4 and the sheet metal top 5 in the nature of a plate having the depending flange 6 at one side for engaging the adjacent flange of the base to locate the top relative to the base. The plate is spaced above the upper edges of the base to provide for circulation of air through the body to assist in maintaining the .top at normal temperature. '7 is a block preferably formed of insulating material locatedrwithin the base 4 and preferably fixedly secured thereto as by means of the bolts 8 and the nuts 9. This block is formed in its lowerface with the continuous groove 10 within which is located the heating element 3. 11 and 12 are posts extending through the 'block and located at one end thereof, the posts being respectively connected to the ends of the heating element 3 and the ends of the Wires 13 for conducting electric current thereto. Suitable insulating material Vla is preferably provided between the heating element and the base. p

The block is preferably provided with the recess 15 into which the flange 6 of the top eX- tends. The block is also preferably provided in its upper portion and near the end opposite to that having the recess 15 with the transverse recesses 16 into which extend the coil spring 1'7., these coil springs abutting the bottoms of the recesses 16 and the top 5, the latter being preferably provided with the bosses 18 for assisting in locating the coil springs. By reason of this arrangement including the coil springs the top is maintained spaced from the base andflbrous band member is also maintained taut.

19 is the handle having at its lower end the furcations 20 with the transverse' ends 21 engaging the end flanges of the base 4, these end anges being preferably reinforced by the blades 22 rigidly secured thereto as by welding and the block 'l being recessed opposite these ends to provide clearance therefor. The wires 13 extend longitudinally within the upper portion of the handle 19 and are clipped to one of the furcations 20 and pass into the body l through one of its open ends. 23 is a suitable electric switch within the upper portion of the handle for controlling the electric current passing through the Wires and 24 is a triggerwhich extends outwardly through the upper portion of the handle and may be engaged by the finger of the operator and moved outwardly to throw the switch into operative position. This switch is so arranged that upon releasing the trigger the switch-will be automatically returned to inoperative position by means of the coil spring 25.

With the construction as above described, it will be seen that a portion of the brous member may be heated to thereby heat the surfacing material, such as wax, and facilitate spreading the latter. It will also be seen that another portion of the fibrous member will remain practically at its normal temperature owing to the openings at the ends of the body encircled by this fibrous member to provide for circulation of air therethrough. As a consequence, the body with the fibrous member may be inverted, the furcations of the handle being suiciently long to provide for doing so, so that this last mentioned portion of the nbr-ous member may be immediately used in the final polishing operation.

What we claim as our invention is:

1. A polisher for floors and the like, which comprises a body, a fibrous member engaging opposite faces of said body, and means for heating one face of said body.

-2. A polisher for floors and the like, which comprises a body having openings at its ends, 110.

a fibrous member encircling said body, and means within said body for heating a portion of said fibrous member.

3. A polisher for floors and the like, which comprises a body having a base member and a top member, a fibrous member encircling said body, means for heating said base, and means operable upon said top for maintaining said brous member taut.

4. A polisher for floors and the. like, which comprises a body having a base member and a. top member, a fibrous member encircling said body, a block within and secured to said base member, a heating element within said block adjacent to said base member, and springs between said block and top member for forcing said top member away from said base member and maintaining said iibrous member taut.

5. A polisher for floors and the like, which comprises a bodyhaving a base member and a top'member, aV fibrous member encircling said body, means adjacent to said base member for heating the same, means operable upon saidtop member for maintaining said brous member taut, and a handle pivotally connected to said body and `providing for locating said base and top members alternatively lowermost.

n6. A polsher for floors and the like compris-.

'7. Apolisher for floors and the like comprisingH a bodyhaving a socketed base member, a top member spaced from said base member, co-

operating means carried by said top and base members for relatively locating the same, a brous member encircling said body, a block Within and secured to said base member, a heating element within said block adjacent to said base member, and means between said block and top member for forcing the top memberaway from said base member and maintaining said iibrous member taut.

V8. A polisher for floors and the like, which comprises a body having a base member and a top member spaced from said base member, a polishingrmember encircling said body, means adjacent tovone of said members for heating the same, means operable upon one of said members for maintaining said brous member taut, and a handle pivotally connected to said body and providing for locating said base and top members alternatively lowermost.

9. A polisher for floors and the like, which comprises a body having base and top members, a polishing member encircling said body, Yand means for yieldably spreading' said base and t'op members to maintainl saidv polishing member taut.

10. A polisher for floors and the like, which comprises'a body having open ends and formed of base and top members, a polishing member encircling said body, means for heating a portion of said polishing member, and means operable upon said top member for maintaining said polishing member taut.
