T0 all whom t may concern.'

Be it known that I, EDWIN C. lVoRNs, a citizen of the United States, and residing at Rutherford, in the county of Bergen and State of New Jersey, have invented a new and lmproved Combined Mop -Head and Mop-Wringer, of which the following is a full, clear, and exact description.

The invention relates to mop heads having a front loop and a rear revoluble loop which, when revolved, serves to wring the mop. Mop heads of the indicated character include a presser frame carrying a front loop, and generally adjustable to vary its angular position relatively to the mophandle.

My present invention provides a new form of presser frame with the front loop integral therewith, and means for adjustably and detachably securing the frame to the handle.

The invention further includes a novel means for revolving the revoluble mop loop.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a .mop head embodying my invention; Fig. 2 1s a front View thereof; Fig. 3 is an enlarged detail view, partly in section, showing the man ner of mounting the revoluble loop; Fig. 4 is a perspective view of the revoluble loop; Fig. 5 is a cross sectional view through the presser frame, and the handle member with the clamping member for securing the frame to the handle member; Fig. 6 -is a cross sectional view mainly on the line 6-6 of Fig. 3; and Fig. 7 is a detail sectional view showing the manner of mounting a portion of the device for revolving the revoluble loop.

In constructing a combined mop head and wringer in accordance with my invention, a handle 10 is provided, and in the present instance isv separate from a handle member 11 in the form of a socket, a screw 12 or the like, serving to secure the handle in the socket.

Projecting forwardly from thehandle member is an arm 13,which carries a presser frame 14, having an integral loop 15, for receiving the front end of a mop A. A revoluble loop 1G in the rear of the presser frame 14 has its shank 17 mounted in a bearing bracket 18 on the handle member beneath the arm 13. A squared portion 19aor equivalent formation on the shank 17 seats a bevel pinion'19 meshing with which is a toothed sector 20, having a bearing on a stud 21 eX- tending laterally from the handle member. Secured to or formed on the sector 18 is a lever handle 22, which when the mop is adjusted for use will rangey forwardly, the outer end extending over the rear end of the presser frame, to thus lie within the side edges of the frame so that a side of the mop may be brought close to a wall.- lVith the sector, and the essentially radial lever handle thereof ranging forwardly when the mop is in position for use, the working thrust of the lever to give a twisting motion to the loop 16 for twisting the mop, is upwardly and rearwardly, and by such upward and rearward motion of the lever handle 22 in the direction of the handle 10, the operator is enabled to apply a l force which will thoroughly and completely twist and squeeze the mop, because the handle 10 may be placed beneath the left arm of the operator, and with the left hand gripping the bar 13. An upward and rearward thrust of the lever by the right arm may be applied to the greatest advantage and with the greatest convenience. With mops in which a crank handle is employed for giving a twist to the twisting loop, the force must be applied with the hands and arms in the most cramped position, so that the limit of force which it is possible to secure with the arms and hands thus cramped, falls very far short of a thorough twisting and wringing of the mop. The positioning of the lever handle 22 so that it will be disposed forwardly over the presser frame has the further purpose and object that in the final wringing move ment the said lever approaches the handle 10, and the iinalforce necessary to be eX- erted for the proper wringing is eiectively produced by the finger' gripping the said handle 10 as well as the lever 22, and drawing the lever .toward thesaid handle. to be noted that the forward terminal of the-lever 9.2 is offset upwardly to overlie the presser frame, and to be spaced from the same for the convenient grasping of the lever. It is furthermore to be noted that the arm 13 is also offset upwardly from the axis of the handle 10. The result of thus osetting the arm 13 is to dispose the pivot of the presser" frame at such a point that the said Itis frame may rock on its pivot to permit the mop cloth A to assume a straight line from the fixed loop 15 to the revoluble wringing loop 16, and the increasing vertical thickness of the twisted mop cloth will thus be accommodated beneath the presser frame, since the latter will be disposed in a plane above and obliquely to a straight line passing between the two loops. The untwisting of the mop cloth permits the presser frame to again drop, and the action of the said frame on the mop cloth when placed against the floor will give the final return movement to the twisting loop 1G.

Un the frame 1l clamp jaws or sockets 24 are provided, that rise above the top of the frame lin alinement with each other, the projections being concaved at the inner sides to receive a round head 23 on the forward end of the arm 13 of the handle member. A bolt 25 passes through the clamp members 2% and the head 13, and receives on its threaded end, a wing nut 26 or the like, for drawing the clamp members into engagement with the said head. The construction provides a pivotal connection between the frame 11 and the handle member; preferably there are two pairs of clamp members 24, in order that the connection with the handle member may be at different points along the length of the presser frame. By loosening the nut 26 on the bolt 25, the frame 14 may rock relatively to the handle member, to dispose the handle at a convenient angle. 1f the nut be tightened up the presser frame will be held rigid with the handle member; but if the nut be comparatively loose, the presser frame may rock on the pivotal connection, so that when the presser frame is lifted from the floor for wringing the mop, the rear end of said frame will contact with the lever 22 and throw the forward terminal of the lever upwardly in position to be conveniently grasped for the wringing movement. The nut may be tightened when the presser frame has been brought down flat against the mop A to give a iixed adjustment if desired. The forward rocking of the handle when the mop is placed against the floor or other surface to be mopped will move the loop 16 rearwardly and increase the distance between the front and rear loops 15, 16, to put the mop under tension, which is done before the tightening up of the nut. wWith the presser frame held in rigid relation to the handle member, the mop can be conveniently employed for working on walls, ceilings or the like. The washer 27 may be employed beneath the wing nut 26.

With the free end of the handle lever 22 disposed directly over and close to the presser frame 14, the mop may be conveniently entered beneath an ice box or other structure or article of furniture. In this position of the handle lever, the twisting loop 16 is substantially horizontal and directly beneath the handle lever but the initial upward movement of the lever handle provides clearance at once for the turning movement. The presser frame, it will be seen, is overbalanced at the front so that when the mop is lifted from the floor, the rocking of the presser frame will tilt the rear end thereof upwardly, to give initial upward movement to the handle lever and dispose the latter in position for convenient grasping and quick rearward wringing movement.

To hold the revoluble loop against turning, a set screw 28 may be provided, which takes into the hub of the sector 20, and is adapted to bind against the stud 21 which holds the sector from turning, and thus through the pinion 19, holds the shank 17 of the revoluble loop against turning. Vhen the set screw 28 is out of binding engagement with the stud 21, the sector may be freely turned by throwing the lever 22 upwardly and rearwardly, a cotter pin 29 serving to retain the sector revolubly in place. The proportions of the pinion 19 and sector 20 are such that a single upward and rearward throw of the lever 22 will serve to give sullicient revoluble movement to the loop 16 to wring the mop, and the user of the mop may thus thoroughly wring the latter without undue exertion, the arrangement being much more effective and requiring less eX- ertion than a crank handle and gear wheel.

It will be observed from Figs. 2 and 5, that the presser frame 14k is formed in two separate side sections joined at their front ends by the loop 15, thereby producing a longitudinal slot 30 between the sections. The said slot extends from the loop 15 rearwardly to and -`through the rear end of the frame 14C, and when the bolt 25 is withdrawn and the frame 14 removed from the handle member, the slot provides a clear passage from the rear end of the frame to the loop for the insertion and removal of the mop A. The rear end of the mop is inserted in the revoluble loop 16, and removed therefrom through an opening 31, the said loop 1G being integral with the shank 17 and in the form of a T-head on the latter. As seen in F ig. 4: the loop extends laterally at one side of the shank and is then return-bent, to range beyond the shank at the opposite side, the extreme end being returned toward the shank, as at 16a, and terminating short of the shank, leaving the entrance opening 31. The loop is formed desirably with an inward bend 32 opposite the end of the shank 17 to give a better grip on the mop A. The shank 17 is removably held to the bearing 1S by washers 17a and cotter pins 17b or the like. rllhe rear end of the shank 17 projects rearwardly through the bearing 18 into a transverse opening 18, said opening accommodating the washer and pin 17, 17h.

The provision of a presser frame with its integral front loop, and the slot extending from the loop rearwardly through the rear end of the frame, provides a convenient construction with the required strength and with the clamping means for securing the frame to the handle member. The mop may be readily placed and removed and the desired adjustments of the parts may be quickly effected.

It will be seen that the coupling members between the handle and the mop frame constitute also a tie between the side members of said frame. Thus in addition to forming the connection with the handle, the said members resist the separating strains `and twisting strains on the side members of the frame.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. In a mop head and wringer, a rigid presser frame having elongated side b ars spaced to form a longitudinal slot extending through the back end of the frame, and an integral transverse mop loop at the front of the frame to hold thefront end of a mop cloth, said loop communicating with the slot, a handled member directly pivoted to the said rigid presser frame at a point forward of the rear end of the said slot, and means at the rear of the presser frame to hold the rear end of the mop cloth, said side bars and front loop constituting the sole presser frame for the mop cloth. l

2. A mop head and wringer, comprising a handle member, a presser frame for pressing the mop against the surface to be mopped, said frame having a transverse front loop to engage the front end of the mop, and being divided longitudinally in the rear of the loop into side sections joined by 'and rigid with said loop, there being a longitudinal slot between the side sections extending to and through the rear end of the frame, members rising from said rigid side sections, means forward of the rear end of the slot, directly connecting the said mem bers on the frame with the handle member, said front loop and side sections constituting the sole presser frame for the mop cloth, a second loop revolubly mounted in the rear of the presser frame to engage the rear end of the mop cloth, and means for revolving the second loop.

3. A combination mop head and wringer, comprising a handle member, a presser frame having a. front loop to engage the front end of a mop cloth, and side members integral with said loop, the said side members being separated by a slot that extends from the front loop through the rear end of the frame, said front loop and side members constituting the sole presser frame for the mop cloth, means mounted to turn relatively to the presser frame for holding the mop cloth and twisting the same, and means directly and separably connecting the handle member with the side members of said presser frame and forming a connection between the said side members across the said slot.

4. In a mophead and mop wringer, a handle member, a presser frame pivotally mounted on the handle member, a. fixed mop loop on the forward end of the frame, a second loop revolubly mounted on the handle member in the rear of the presser fra-me, and means for revolving the said loop, said vmeans consisting of a pinion on the shank of the revoluble loop, a toothed sector mounted to turn on a horizontal axis at a side of the handle member and meshing with the said pinion, and a lever handle rigid with the sector, said handle when the mop is. in the normal position for mopping, being disposed in a forward direction to overlap the frame and lie close to the latter near the rear of the same, said presser frame having pivotal connection with the handle member between the center of gravity of the frame and its rear end to cause said frame to rock on its pivot when the mop is lifted from a floor, whereby to contact at its rear end with the front end of said lever and tilt the said front end upwardly, the sector being disposed at the under side of the lever, and an upward and rearward throw of the lever away from the frame serving to give a twisting movement to the revoluble loop.

5. In a mop and wringer, a handle member, a presser frame, a mop loop on the forward end of the frame, a rear mop loop mounted to revolve, a mop cloth on said loops and means for revolving the second loop, said means comprising a pinion on the revoluble loop, a toothed element mounted at the side of the handle member to turn on a substantially horizontal axis, and meshing with the said pinion, and a lever' rigid with the said toothed element, said lever when the mop is in the normal position extending forwardly fiom the toothed element beyond the rear loop and above the presser frame and lying close to said frame, said lever being movable upwardly and rearwardly toward the handle, from its position over the presser frame to turn the toothed element and pinion, a. movement of the lever from the front position to a position adjacent to the handle serving to effect a wringing of the mop cloth.

6. In a mop, a handle having a forwardly projecting arm at the front end, a presser frame on the front end of said arm, a loop on said frame on the front, a rear revoluble loop on the handle, a mop cloth on said loops, a forwardly extending lever on the handle, said lever having its forward free end normally adjacent to the presser frame and i'ockable to a position to bring the said free end adjacent to the handle at approximately the end of the swinging movement so that the hand of the operator may grasp both the handle and lever, and gear connections between the lever and the revoluble loop, said connections being adapted to turn the revoluble loop and to effect the final twisting of the mop cloth as the lever approaches the handle.

7. In a mop, a handle, a presser frame pivotally mounted on the handle and provided with a front loop to receive the front end of a mop cloth, a revoluble twisting loop adapted to receive the rear end of the mop cloth, a pinion on the twisting loop, a gear element in mesh with the pinion, and a lever fixed on the said gear element and normally disposed in a forward direction, the free end of the lever overlying the presser frame and twisting loop, when the mop cloth is in the untvf'isted position, said lever being movable upwardly and rearwardly to effect a turning of the twisting loop, the twisting loop being in approximately a horizontal position beneath the free end of the lever handle when the mop cloth is in the untwisted position for use, and the initial rearward movement of the lever affording clearance for the turning of the twisting loop.

S. In a mop head and wringer,`a presser frame having elongated side bars spaced to form a longitudinal slot extending through the back end of the frame and having an integral transverse mop loop at the front of the frame and communicating with said slot, a handle member, a transverse bolt passing through the sides of the frame and through the forward end of the said handle, bridging the slot of the frame and detachably connecting said handle and frame, a nut on the bolt adapted to bind the frame tightly against the handle member to prevent relative movement thereon or to permit pivotal movement of the frame on the handle member, means in the rear of the presser frame to hold the rear end of the mop cloth, and means for twisting said last mentioned means.

In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
