AB STRUCTURES FOR USE oN SMOOTH sURFAcED FLOORINGS AND THE LIKE Filed July 1o, 1941 .7a/zia :102m By my f Patented Mar. 6, 1945 METHOD OF MAKINGy MOP FRAMES FOR SWAB STRUCTURES FOR USE ON SMOOTH y SURFACED` FLOORINGS AND THE LIKE John S. Brennan, St. Louis, Mo., assigner to J. S. v

Costello & Son Brush Co., St. Louis, Mo., a corporation of VMissouri Appunti@ July 1o, 1941, serial 1810.401363 2 claims; 01. 30o-2i) This invention relates to certain new and useful improvements in a mop frame and pertains more particularly to theframes of that character of mops known to the trade as dustless sweeper mops for use of smooth-surfaced floorings and whereby the swab structure of the mop is readily removable or replaceable and/or reversible if the swab structure is a double-faced one.

An object of the invention is toprovide a mop frame of an improved` construction.

Another object of the invention is'to provide an improved supporting frame for the 'swab structure and the handle of the mop, and Athe frame if desired, -`may be vprovided -with oiling ducts. l

A further object is tofprovide a mop frame with an improved handle supporting head.

A still further object is to provide a mop frame of an improved tubular construction.

' 4It is also an object of the invention to construct a mopv frame by an improved method.

With the foregoing and other objects in view which. will appear as the description proceeds, myinvention resides in the combination and arrangement of parts and in the details of conbeing understood that changes may be made within the scope of what is claimed without departing from the spirit of the invention.

Anembodiment of the invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a plan elevation partly in section of a mop showing this improved mop frame supporting the swab structure of the mop and the handle. n

Figure 2 is a plan elevation showing how" this improved mop frame is constructed.

Figure 3 is a perspective elevation of the mop frame head.

Figure 4 is an enlarged transverse sectional elevation taken approximately on the line 4-4 of Fig. 2. v

Figure 5 is `an enlarged transverse sectional elevation taken approximately on the line 5-5 of Fig. 1.

Figure 6 is an enlarged fragmentary longitudinal sectional elevation taken on the line 6-8 of Fia-5.

Referring by numerals to the accompanying drawing, 1 designates the mop, 8 the frame, and 9 the handle therefor.

The mop 1 as shown, comprises a doublefaced swab structure I0 of a pair of opposing secured together layers II having twine strands I2 secured to and extending outwardly from each layer, and the swab structure being open-.ended so that it can be slid from either end onto the supporting frame 8 before the handle 9 is fixed to the mop. l

f The frame 8 is of tubular structure and; is formed from a suitable tube length of relatively large diameter-and has rounded ends I3 which are formed when making or constructingthe frame.` f' i 4In making the frame, a tube of the requiredV length for a frame of a desired size is selected, and the tubular length is marked as designated at I4 in Fig. -2 at the middle or center of its length, and an endI5 of the tube is engaged `and bent into a position paralleling the intermediate portion I6 ofthe tube on a required form of bend I'I, with the extending end I8 of the pari-[I5 of the'tube intransverse alinementy with the mark I4.

A handle supporting head I9 having end disposed openings 20 and 2| respectively, and paralleling each other, is engaged for mounting on the partly formed tubular length with the opening 2I engaged on'the straight portion 22 of the tubular length, and the head I9 is slid thereon to a position so that the opening 20 of the head can' be engaged on the part I5 to the position shown in full lines in Fig. 2, and the head Iis left in this position while the extending part of the straight portion 22 of the tubular length is being bent into a position in longitudinal alinement with the part I5 and wherein the extending endf23 will be positioned in proximity to the extending end I8 of the part I5. In bending the straight por-1 tion 22 of the tubular length into the position shown at 22a in dotted lines in Fig. 2, the bend 24 is formed, the bends I1 and 24 thereby forming the rounded ends I3 respectively, of the frame 8.

The head I9 ateach end is provided with a pair of vertically disposed apertures 25 for alinelment with respective apertures v26 which areA formed in the tubular length when the head is moved to the position shown in dotted lines at I9a, with the part 22a of the tubular length engaged in the opening 20 of the head. Pins 21 are then mounted and riveted in the alined aper tures 25 and 26 for securing the head t'o the frame. f

The head I9 on its top side 28 is provided with an inclined socket 29 for the ferrule end 30 of the handle 9, and at the bottom of the socket is' an inclined seat -3I having a. slot 32 therein which is open at one end for the reception of a threaded stud -33 which is secured to and ex duct 31 which is drilled from the front end 38' of the head, through the opening 2| andthe well 34 and to the opening 29j-as iiire clearly shown in Figs. 4 and 5, before the'head-.is mounted on the frame 8.

In centrally disposing the head I9'1th fratrie 8 in the manner shown in dotted-lines at IlSltin Fig. 2, the end 39 of the duct 31 will provide a site opening for locating the center mark l4- with respect to centrally positioning the head on the frame for pinning the head to the frame.

V.Each of the layers l! of Athe swabvstructure l0 intermediate its length, isprovided with asl-,it oropening 49 for introducing the ferrule end 30 'of the handle 9 for securing the handle to the head i9 of the Vvframe 8 after the frazne has. been slid intothe swab structure from either end.V

The handle 9r` having the stud. 33 and tighten-A ing' nut 36A threadingl'y mounted on. the .stud and held thereon against removal by the burred end 4l on the stud, upon `being engaged Ain the slit lof ther-upper layerv Il of the swab structure {D} is manipulated to guidingly engage the opposing sides ofthe nut between the opposed guide walls. 39 inthe vhead l9so. that thatportion of the stud lbetween the nut and the' ferrule end of the handle can bedrawn into theslot 32. or the seat" 3 and.. so thatthe ferrule Iendvl of the handle can be seated inthe socket29 ofthe head.A Tighteni'ng turning of the handle 9 will cause the nut 36 to ride upwardly on the thread of the st'd 33 4ley reason of" the nut being held against turning by the opposed guide walls 35, the'turn ing of' the Ihandle being continued until the Aferrule end 3U thereof isrmly-seatedin the socket 29 of the head and against the seat 3|. Thermop is then 'ready for use on..smooth-surfacedgfloering'sand the like. l

Ohviousl-y, when one twine strand layer of vthe swab structur 'I has heen suciently used, the

swab structure can beremoved from the frame 8 for reversing the working surface thereof, after removal of the handle from the head I9, which is done by turning the handle in a loosening dlrection.

The tube -of the frame 8 may on its underside, be provided with spaced apertures 42 so that an oil treatment 'for' the swa'bstructurei In can be provided by depositing olll in tlie'well- '34 from where it will enter the duct 31, and can be com- -x-nunicated to the apertures 42 'by entering the ytuhe through .the opening 43 at one end of the Cbifiously'the securing of the head i9 to the Aextending ends of the tube-of the frame 8 prevents the tube ends from separating, and by reason of the frame being of tubular construction and the head being somewhat hollowed to providethe` handle securing vconstruct-ion shown; a relativelyA light weight mop frame is provided.

What' I claim is: l 1. vThe method `of making a mop framefrom a length of comparatively rigidmaterial; consisting of -bendinglthe material lengthtoprovideila pai-roi paralleling straight portions of; unequal lengths, of slidably mounting a handle lsupporting head on the parallelingl portions, of bending the longer one of the paralleling portionsleavinga suitable straight portion thereof to .for-rn apart in axial valinemexn; with the other straight por-v tion, and oi slidab'ly positioning and securing-the heady over said axially alined portions.

2.
