To all whom it may concern.' v

Be it known that l JoHN F. KELLY, a c1tizen of the United btateS, and resident of Elkins, in the county of Randolph and State of West Virginia, and useful Improvements in Floor and Wall Mops, of which the -following is aspecification.

This invention relates to the class of brushing The object of the invention is to provide an improved, novel, simple and efficient mop of the class described adapted to hold a suitable mop head of cloth such as tufted fabric provided with a pile surface, or. loosestrands doubled upon themselves, and 1n whlch provision is made for rinsing the mop 1n a bucket or other suitable receptacle or for wringing the same, the cloth of the mop being also adapted to be rendered taut or placed under tension when in a position for use or to be released or freed thereof to hang loosely during the wringing or rinsing operation.

A further object of the invention is to provide a novel holder for the mop cloth, together with means for anchoring the ends thereof and for imparting a spiral or revolving motion to one end of the mop cl'ot whereby the water or cleansing Huid may be wrung or compressed therefrom, novel means being provided for this purpose, while provision is also made for clamping a brush upon the mop holder for use as desired, in conjunction with the mop.

With these and other objects in view, my

invention consists in certain peculiarities of construction, novel arrangements and operation ofthe various parts of the device as will be hereinafter more fully set forth and specifically claimed.

In the drawings,

is a central longitudinal sectaken along line 4-4 of Figure a fragmentary bottom view of and-scrubbing and more especially to a combined floor and wall mop.

Referring to the drawings in detail, vin whlch for purpose of illustration is shown the preferred embodiment of the invention and in which like reference charactersdesighave invented certain new\\nate corresponding parts throughout the several views, my improved combined floor and wall mop 1s shown jas embodying a handle 5, preferably somewhat elongated and of circular cross section, adapted to carry the operating parts of the mop includingthe mop holder and wringing device to be hereinafter described.

Mounted on the lower threaded portion of the handle is a sleeve 6 threadedv or otherwise retained thereon as indicated at 7, the sleeve being shown internally threaded for engaging the externally threaded portion of the handle in the form shown.

This sleeve carries the mop holder and for this purpose, there are provided upon opposite sides of the sleeve or attaching member 6, a pair of outwardly and downwardly branching arms 8, the lower portions of which are disposed in substantially parallel relation and are provided with outturned lower extremities 9 forming pivots normally sprung outwardly by reason of the resiliency of the material forming the arms. The` arms are preferably formed of resilient h or spring steel or other suitable springing 'Kmateriah but they normally spring apart, said parts being also of round stockmaterial as are the parts now to be described.

The mop holder proper consists of a substantially oblong or rectangular frame formed of a strip of material bent intermediately of its ends to form a front or connecting portion 11 and side portions provided with pivot ears 12 engaged bythe outwardly directed' pivots 9, the ears projecting upwardly from the side portions for this purpose. The inner or rear extremities of the side portions of the frame 10 are directed inwardly toward each other and substantially in alignment in opposite directions, as indicated at 13, these portions being designed to form stops for limiting the pivotal movement upwardly of the adjacent end of the frame. The side portions of the frame 10 Lare also braced and connected in the relation described through the medium of relsay atively flat cross strips or braces 14 disposed upon opposite sides of the pivots 9 with respect to the longitudinal dimensions of the frame and the pivot aXis thereof.

`It is also pointed out that the portion of inwardly directed portions or stops 13 serving by contact with the arms to limit the said upward swinging movement. It is also pointed out that the cross strips or braces 14 are disposed to project beyond the diameter of the side portions of the frame and at the front portion of the frame slightly spaced in rear of the connecting portion 11 is a cross bar 15, around which the rnop cloth proper 16 is folded or extended, as more clearly shown in Figure 2 of the drawings. The mop cloth is formed of a strip of tufted or pile fabric, or strands of soft material as commonly used in mops, and in practice is folded on the cross bar 15 intermediately of the strips of which the mop cloth is formed and then extended under the cross strips or braces 14 with the rebent portions disposed in contact, and then extended upwardly around the rear cross brace or strip 14, being retained in position between the sides of the frame 1() and held from displacement by the inwardly directed portions 13. The mop cloth is also prevented from shifting laterally when in use, being confined between the sides of the frame both at the front and rear ends of the 'frame and the active or contacting portion of the mop cloth, when in use.

Projecting rearwardly from the sleeve or attaching member 6 is an apertured guide arm or bearing 17, and mounted on the handle considerably up from the bottom there is a collar 18 having a similar rearwardly projecting guide arm or plate 19 disposed in alignment with the bearing 17 said arms or bearings rotatably receiving the upper and lower extremiticsof a spiral feed member or screw 20, preferably formed of two intertwisted wire rods as shown. The screw is supported againstlongitudinal displacement by a collar 21 fixed to the screw by a set screw or the like 22 in position so that the collar will engage the arm or bearing plate 17 thus preventing the screw from shifting downwardly by its weight. The lower ends i connected and a detachable jaw or plate 25 having a central aperture for engaging a screw shank 26 carried by the Jaw 2t whereby the extremities of the strip forming the mop head 16 engaged on said screw shank,

may be clamped between the jaws or lates as clearly shown in Figure 2 of the rawings, a thumb nut or the like 27 being mounted on the screw shank in order to secure the parts in binding relation.

In order to impart a revolving motion to the spiral feed screw so as to twist the mop head for the purpose of wringing or rinsingr the same, an operating nut inthe form of a cylindrical handle 28, is provided, said handle having a longitudinal bore 29 receiving or engaging the feed screw 20 and having oppositely and inwardly directed pins 30 disposed intermediately of the length thereof and opposing each other in the grooves of the spiral screw 20 at their tapered ends 31, so that when the rear end of the frame 10 is swung upwardly against the arms 8, the

operator by grasping the handle 28 and moving the same downwardly over the screw,

will impart a revolving motion thereto, so

amount of space in this position. On shift ingv the nut or handle in the opposite direction so as to move upwardly on the spiral screw, reverse motion is imparted thereto and thus to the free end of the mop cloth so that the latter is'then untwisted and permitted to assume its working position. When the mop is in use for mopping floors or walls, pressure downwardly above the handle while the forward end of the mop is in contact with the surface to be cleaned, will render the mop cloth taut as clearly shown in Figures 1 and 2 of the drawings, the strip being placed under tension around the brace or cross strip 14 near the rear end of the frame and between the side portions thereof, while being also held from displacement by the inwardly directed extremities 13 forming shoulders for this purpose, as well as serving to limit the upward movement of the short end of the frame against the arms 8 when the device is in an inactive position.

If desired thereniay be mounted upon the top of, the frame 10 at the forward end thereof, a brush 32, thev head thereof beingr carried upon an anchoring block 33 preferably of triangular cross section, with the hypotenuse of the triangle disposed to eX- tend upwardly and forwardly, whereby the brush is supported in a forwardly inclined position. The block 33 may be suitablysccured to the framel and as shown` is retained. against the connecting or bight portion 11 incense and the sides of the frame, as by means of clips 34 apertured and engaged by screws 35 for securing the same to the ,block at the base thereof disposed toward the frame and having curved jaw portions engaging the sides of the frame so as to detachably but to the arms and the handle while the brush is being used.

By means of the det/ice described, the mop can be wrung or rinsed without the necessity of dipping the hands in the water or wetting the hands, or subjecting the hands and wrists to strains incident to twisting a mop as is usually done. While l have shown anddescribed the feed screw as made up of two relatively stiff wire strands so as to produce a sharp pitch, it is to be understood that the' screw may be of any well known or preferred form and consist of a bar cut to produce the spiral groovesfor engagement by the operating member 28. lt will also be understood that while l have now illustrated what l consider to be the preferred embodiment of my invention, changes in the constructions, arrangements, proportions and forms ofthe parts shown may be made so long as the same do not depart from the spirit and scope of the invention as claimed.

Having thus described the invention what l claim is l. A mop comprising a supporting member, arms carried by the supporting member, a frame pivoted to the arms, a mop cloth comprising a strip folded upon and beneath the trame, said frame being formed to prevent displacement of the strip, the extremities of the strip being disposed in contact, a feed screw carried by the supporting member and having one end 'thereof connected to said extremities of the strip, and an operating member in the form of a nut en gaged en the screw for movement longiudinally thereof to impart a revolving mo tion to the screw so as to twist the strip.
