UNITED STATES DRY Mor' Application led February 27', 1929. liSerial No. 343,(1'2'l'l` This invention relates to dry mops and clusters and particularly to that type of such implements which are intended for cleaning floors and Walls in dry condition to remove dust particles adhering thereto.

It is the particular object of the present invention to provide an implement of this lkind which performs the above stated operation in an improved manner and which prevents the dust removed thereby from being scattered about and from being deposited at other places.

`With this and other objects in view the invention consists in a novel combination of cleaning materials of different character in the same mop, in a novel arrangement of details of construction as hereinafter more fully described and finally pointed out in the appended claims and as illustrated in the drawings which form a material part of this disclosure and in which:

Fig. 1 is a front elevation of my dry mop from which parts of the cleaning material are removed to show the frame construction.

Fig. 2 is a sectional elevation on line 2-2 of Fig. 1. l

Fig. 3 is a perspective view of my dry mop.

Fig. 4 is a detail side elevation of the frame joint at 4-4 of Fig. 1.

Fig. 5 is a detail sectional plan on lines 5 5 of Fig. 1.

Referring to the drawings, 10 is a mop frame having the shape of an elongated loop consisting of two'wire strands 10a and 10b twisted about each other and holding mop material 11 of an absorbent nature, as cords of wool or cotton, between the twisted wire strands. The free ends of the loop-forming wires 10 are held within the tubular portion at one end of a helical coil of wire 12 While the opposite end 14 of said coil is adapted to hold a mop stick 13. The wire ends 10 are preferably held in coil 12 by means of a screw 15 which presses them against the turns. of

said coil as shown in Figs. 1 and 5. The wires 10 and 10a are separated from each other at the center of the curved opposite ends of the loop to form ring-like apertures in the frame as shown in Fig. 4. These apertures accommodate the Iends of a second pair of twisted t-0,11` 1111013.01" ,soft ,or ahsorbentmaterial ,-iipon .other places- .'ThS l0-tien iS further imwir@ strands L6 which hold y.C;1..,21I1f1ped between their turns brush material 17 of a harder @Habs/@fliegt kind edera/@liar a Sharp Clearme action as. .Stiff bristles r vegetable ber as piassava or the like.

The Clewneetien .ef this dry mop J(.iers' considerably from that `of. Adlevyices and is particularly efliciellt for painted yyalls. Qn 1surfaces cftlls. kinddust particles are'held tightly lelectrical attracf not sharp enough to loosen these particles from the Wall and a brush ofloris-tl'es for the llie which capable `of loosening .them dis- TbiatsS the .duet-@P011 aeghbrmg- Well Perf tions by `whir'sh they are .qiii'clgly'attractedl i lt .f is there fone rquite eyident that neithera brush nora mop cap zfurnish a thoroughandellicient oleailingatlon. My invention .remedies this ilefe by thecembaed actl LL the brush 17 ofshp and @tiff-'matriel which .lQDSenSi-th dest esieitly if-lfQm the-(vallend of [the ab* sorbent soft rriaterfial L11 which completely .Y surrounds 17 :to whichthese particles before they can escape `toibe redeposited provedby the .action of :static electricityvvhich iS ee11eratffl`byfrit0n 'Of wbrsfle lead mep' material-@smeet the welll. ,135 'this fric: $10.11 the Wall "receives "negative eleri charge-particularly when covered'withl res- 1 inous paint. 'llhe ibristles vof the brush remain approximately neutre-l electrically alle .the soft woolly mop material receiyesa positive electric char-ge in-faccordancewith theirelectro'staticqualities. Itis therefore quite clear ,9 5

that dust particles which are loosened from the wall surface by the mechanical action of the bristles are strongly attracted by the posi tively charged mop materialwhile they are repelled from the Wall and in lesser degree 1x00' from the bristles of the brush. No such improved action could take place if the brush and surroundingpmaterial had the same mechanical or electrical qualities. The resiliency of the coiled spring holder 12 allows the plane of loop to adjust itself parallel to a wall or other surface under a light pressure, While the handle 13 forms different angles therewith so that no opening for the escape of dust is available. It-is another .advantage 0f the manner of mounting' brush 17 that when its exposed faces are used up or dirty, it may be rotated 90 degrees in frame 11 after loosening ends 16a and 16?), whereby a new cleaning portion is exposed and it may belocked again by rebending the ends 16a and 165 around ,10a

Having thus described my invention what I claim as new and vdesire to secure by Letters Patent is:

1'. mop head comprising a handle `enH gaging part, amop handle, a looped frame held by the handle engaging part, soft, absorbent mop material on said frame,a shaft traversing said loop having its ends fastened thereto perpendicularly to said mop handle'and bristles adapted for sharp cleaning action'on said shaft within the'hollow portion of said loop. u 2. A mop head comprising a handle engaging part, a mop. supporting member attached f thereto, limp and absorbent mop material `carried by said supportingmember and a brush consisting of stiff cleaning material held on said supporting member within the central part of said loop and surrounded by said absorbent material.

3. A mop comprising a mop holder, a mop head'held thereby, said head comprising .a looped frame supporting. mop material, bearings fornied by said frame at opposite sides of said looped frame, a shaft mounted in said v` bearings, bristles on said shaft forming a brush Within said frame and means to lock the ends of saidshaft to ysaid frame.

4;. In a mop head the combination of a shaftV having stiff cleaning material radiating therefrom forming a cylindrical brush, aloop of wire strands holding softdusting material intertwisted therebetween, opposite ends of said shaft being held by sai-d4 wire strands at diametrically opposite places of said loop, n

said vsoft material encompassing the stiff cleaning material on said shaft and clinging closely thereto. l
