MOP FRAMES Filed June 18, 1956 United States Patent assiguors to Denim Maid Manufacturing Company, Inc., Newark, Ohio, a corporation of Ohio Application June 18, 1956, Serial No. 592,101

11 Claims. (Cl. 15-147) Our invention is a novel improvement in mop frames for household or industrial use, and the principal object thereof is to provide a mop in which the mop head of elongated shape may be readily adjusted throughout an angle of 360 degrees with respect to the axis of the handle, so as to enable the head to be used for mopping wide areas, narrow v crowded areas, under low furniture or radiators, in a simple and eflicient manner, the mop frame being designed to turn a full 360 degrees for wide or narrow use, and the head positively, or frictionally, locking in any adjusted angularity.

Another object of our invention is to provide a mop frame of the above type having no parts which are subject to excessive wear, thus giving long service to the mop under hard use.

Other minor objects of the invention will be hereinafter set forth. 7

We will explain the invention with reference to the accompanying drawing, which illustrates one practical embodiment thereof, to enable others familiar with the art to adopt and use the same; and will summarize inthe claims, the novel features of construction, and novel combinations of parts, for which protection is desired. In said drawing: Fig. 1 is a plan view, partly in section, of our mop frame with dusting head attached thereto, showing the frame disposed with respect to the axis of the handle for mopping areas of small width.

Fig. 2 is a view similar to Fig. 1, but showing the mop frame adjusted through an angle of 180 degrees with respect to'the axis of the handle.

Fig; 3 is an enlarged vertical section on the line 3-3, ig 1 r lFig. 4 is a view similar to Fig.3, but showing the handle pressed downwardly towards the mop frame preparatory to rotating the handle into a different angularity with respect tov the longitudinal axis of the mop frame. -As shown, our mop frame preferably comprises a stiff open frame of wire or the like and of elongated shape, the same consisting of parallel sides 1 and 2 connected 'at each end by a semi-circular portion 3, upon which elongated frame 13 the dusting head 4 is adapted to mounted. The dusting head is preferably made of yarn such as six-ply yarn, for dusting efficiency, the yarn 'being double-stitched as at 5 to heavy pre-shrunk denim cloth 6 of substantially the same shape as the mop frame ;'1-"-'3, as in Fig. 2, the mop head being adapted to be removed from the frame for washing, or secured by tie strings or the like in position upon the mop frame 1-3, *the particular manner of removably securing the dusting head 4 to the mop frame 1--3 forming no part of our present invention.

2,893,035 Patented July 7, 1959 At approximately the center of the mop frame 1- -3 is a metallic plate 7 of relatively narrow width having its ends rolled as at 8 over the wire members 1 and 2, as shown in the drawing, the plate being fixed against axial movement on the frame 1-3 in any desired manner.

At the center of plate 7 is a vertically disposed cylindrical member 9 which may be secured by spotwelding or the like to the plate 7 to prevent lateral movement of the cylinder on the plate; or such movement may be prevented in any other desired manner, such as juggling the center of the plate 7, as at 7a (Figs. 3 and 4), to suit the inner diameter of the cylindrical member 9.

Upon the top of the cylinder 9 is an inverted cupshaped member 10 having a downwardly extending peripheral flange 10a of substantially greater diameter than that of cylinder 9; and member 10 is secured in position upon cylinder 9 by rivets 11-12 (Figs. 3 and 4) passing through perforations in member 10 and plate 7 and passing through the cylinder 9, said rivets having heads at their extremities engaging the top of member 10 and the bottom of plate 7 to securely lock the parts in position.

As shown, the depending flange 10a of member 1 is provided with pairs of diametrically disposed notches 10x, the pairs being preferably equally spaced apart, for the purpose hereinafter described.

Vertically slidably mounted on the cylinder 9 between member 10 and plate 7 is a second cup-shaped member 13 having an upstanding peripheral flange 13a provided with a pair of diametrically opposed notches 13x for the purpose hereinafter described, the flange 13a of cupshaped member 13 being of smaller diameter than flange 10a of member 10 so as to fit within the same under normal conditions.

The cup-shaped member 13 is normally urged upwardly within the inverted cup-shaped member 10 by means of a coiled spring 14 or the like disposed around cylinder 9 between plate 7 and the bottom of cup-shaped mem ber 13. I u

A mop handle is provided, same consisting of a handle member 15 from the lower end of which extends a pair of divergent arms 16 of stifi wire or the like, the lower ends of which arms 16 are inturned as at 16a, the same being diametrically opposed and extending substantially to the cylinder 9, the inturned ends 16a passing under the flange 10a of member 10 and being seated in the opposed notches 13x of cup-shaped member 13, thereby hingedly connecting the handle 15 to the mop frame 1-3, the spring 14 normally urging the inturned ends 16a upwardly into contact with the lower edge of the downwardly turned flange 10a of member 10. One pair of notches 10x in member 10 are so disposed'that. when the inturned ends 16a are engaged therein the axis of handle 15 will be positively locked at right angles to the longer axis of mop frame 13, whereas another pair of notches 10x are so disposed that when they inturned ends 16a are engaged therein the axis of handle 15 will be disposed in alignment with the longer axis of the mop frame 1-3, as in Fig. l. The thrust of spring 14 would normally be suflicient to frictionally bind the inturned ends 16a of the handle against the lower edge of flange 10a of the member 10 in intermediate adjusted positions.

In, order to adjust the angularity of the frame 1+3 with respect to the handle, with the mop frame contacting the floor or other surface, the operator would merely raise the handle into vertical position and exert a slight downward pressure on the handle sufliciently to compress the spring 14 so as to free the inturned ends 16a from the notches 10x or flange 10a of member 10. The operator would then simultaneously rotate the handle throughout any desired amount, the same being freely rotatable through an angle of 360 degrees, and thereby bring the axis of the handle into any desired angularity with respect to the longer axis of the mop frame 1-3. The operator would then release the downward pressure on the handle, whereupon the spring 14 will urge the inturned ends 16a upwardly against the lower edge of flange 10a of member 10, either engaging a pair of notches 10x or merely frictionally engaging the said lower edge of flange 10a, whereupon the mop head 1--3 would normally retain the adjusted angularity with respect to the axis of handle 15, the same being either positively locked in the adjusted position by the notches 10x, or frictionally locked 'in position by engagement of the ends 16a against the lower edge of flange 10a. Thus our mop may be used for large areas, small crowded areas under low furniture or radiators, and will efliciently dust or clean the desired surfaces.

The dusting head 4-6 may be readily removed or detachedfrom the frame and may be washed over-andover again.

We do not limit our invention to the exact form shown in the drawing, for obviously changes may be made therein within the scope of the claims.
