To @ZZ whom lit may concern:

Be it known that l, lVrLLrAM H. Cox, a citizen ont the United States, residing at Collegeville, in the county of Montgomery and State of Pennsylvania, have invented certain new and useful Improvements in Mops, ot which the following is a specilication.

One object of my invention is to provide an improved mop ot the type including wringing rollers and which can be easily and quickly manipulated by a continuous rotation of' a hand crank in the same direction to thoroughly wring the cloth.

Another object is to. so construct my iinproved mop that the cloth can be easily and quickly removed and replaced without the entire removal of any securing screws, springs or other small elements; it merely being necessary to loosen adjusting screws to permit the removal of one of the rollers together with the cloth.

`A further object is to so make the mop ot my present invention that wear can be brought upon all parts of the cloth and for this reason a cloth used in connection with a mop which is made in accordance with my present invention will last an exceptionally long time and give good service until all parts thereof have been worn by use.

Another object is to make my improved mop of a simple and durable construction which can be easily 'and quickly manufactured.

These objects, and other advantageous ends which will be described hereinafter, l attain in the following manner, reference being' had to the accompanying` drawings in which-- Figure 1 is a iront elevation oi my improved mop; a portion ot the handle being broken away and the cloth omitted,

Figure 2 is a side elevation of Figure l; the lower portion of the main frame being broken away to reveal the mounting of the wringing rollers, i

Figure 3 is a View of similar character to Figure 1 drawn on an enlarged scale and showing the adjusting screws having been backed oit to permit the removal or' the upper roller,

Figure Il' is a side elevation ot' Figure 3 showing in full lines the upper roller having been removed and in dot-and-dash lines said upper roller prior' to the removal et tie same,

Figure 5 is atop plan view of Figure 3,

Figure t3 is a side elevation ot Figure 1 looking in the direction oi' the hand crank,

Figure 7 is a detail front elevation ot a yolred auxiliary iframe which :forms a part oi? my invention,

Figure 8 is a side view ot Figure 7,

Figure 9 is a top plan view of a slide bolt which l preferably employ for locking thehand crank in position during the use or. the mop, and

Figure 10 is a fragmentary section taken on the line 10-10 of Figure 3.

Referring to the drawings, 11 represents a looped main `trame which is preferably formed of strip metal which is bent in the shape illustrated in Figures 1 and 3; the same including substantially parallel sides l2 and 1S, abase 11i which is substantially at right angles tothe sides 12 and 13 and two slanting top portions 15 and 1G which are bent substantially parallel at their ends 16 to embrace a pole handle 17. llhe ends 16a are preferably secured to thepole handle by a rivet or screw 18 which extends through said handle. in operating roller 19 is arranged substantially parallel with and closely adjacent the base 14l and has axle portions 2O and 21 which are journaled in circular holes in the respective side portions 12and 13 oij' the main frame 11. rlhe axle portion 20 is continued outwardly beyond the side 12 oi. the main trame to provide a hand crank tated. A. yolred auxiliary iframe 23 is positioned. within the main trame 11 with its 'top bar 24 extending transversely between the upper portions of the sides'l and 13.

The leg portions Q5 and 26 of' 'the a uriliarv 'trame 23 extend substantially parallel with the inner sin-faces ot the sides and 'let the main :trame and include' notches 2"? which curve inwardly and upwardly from the edges 28. These notches duringi the use of the mop form bearings at their inner and uppermost portions tor the axle trunnions 29 of another roller 3() around which the mop cloth 31 extends; said mop cloth being shown in dot-and-dash lines in Figure G. The mop cloth is normally held between the rollers 19 and 30 by resilient means `hereinafter described. The leg portions 25 and 26 of the auxiliary frame 25% have outwardly projecting pins 82 which entend into slots 33 which are formed in both t the sides 12 and 13 of the main 22 by which the roller 19 can be roframe; said slots 33 being preferably formed `entirely within the width of the sides as clearly shown in Figures 2 and 3. The lower ends of the legs 25 and 26 ofthe auxiliary frame are bifurcated so that the urcations 34 extend at opposite sides ot'y 'sure bar 38a; said pressure bar extendingsubstantially parallel with and above the top bar 24.

' i Coiled springs 38 are interposed between the pressure bar 33at and the top bar 24 oit the auxiliary frame and surround the posts 35. A transverse bar 39 has yits opposite ends secured respectively to the oppositely sla-nting top portions 16 and this bar 39 'has screw threaded holes 40 through which pass pressure adjusting screws 41; said pressure adjusting screw bearing on the top of the pressure bar 382L and having heads 42 withinthe space 36; said heads being preferably knurled so that the screws can be easily turned by the fingers; Thus by turning downen the screws 41 the-auxiliary frame will be moved toward the base 14 of the main rame'through the medium of the springs 38 and the roller 30 will be resilient` ly pressed against the portion of ythe mop cloth 31 which extends between itland the roller 19.

y f'The transverse bar 39 is preferably provided with a clip 43 which has ears 44 bent upwardly so as to embrace the lower end or" i, the pole handle 17 said pole handle preferably extending into the crotch space 36; Screws 45 or other suitable securing means extend through the ears 44 and provide additional securing means for the handle 17.

A slide bolt 46 has an elongated slot 47 through which rivets 48 on the slanting portion 15 of the main frame extend. The lower end of the slide bolt 46 vis forked as shown at 49 and is adapted to slide into a position to `embrace the hand 'crank 22 at a point remote from theV operating roller 19 so as to secure the hand crank against 'accidental rotation during theuse of the mop. The opposite end 50 of the slide bolt is preferably bent at an angle to provide a hand hold to permit the forked end 49 to be withdrawn from embracing position with the hand crank 22 when it is desired to wring the mop cloth 31 by turning the hand crank to rotate the roller 19.

The notches 27 extends inwardly and upwardly to such extend that when the parts are in their operative position to permit mopping, it is impossible for the roller 30 to accidentally move out or said notches 27. 1n other words, as shown in Figures 1, 2 and 6, it is impossible for the axle trunnions 29 to move downwardly in the notches 27 sutliciently to vbe freed of the auxiliary frame. However, by backing olf the adjusting screws 41 into the positions shown in Figures 3 and 4, the auxiliary frame can be moved into such position that the roller 30 can be moved out of the notches 27 and the mop cloth can then be slid from the roller 30 for 'purposes of replacement or repair. rllo re-insert the mop cloth and roller 30, it is merely necessary after the mop cloth has been passed around the roller 30 to insert the axle trunnions 29 upwardly in the notches 27 and tov screw downon the adjusting screws 41. This action will move the roller 30 so as to compress the cloth 31 between the rollers 19 and 30 and any desired degree of resilient pressure can be imposed upon. the mop cloth according to the amount the adjusting screws are turned; it being noted that the springs 38 serve as a resilient cushion so that the direct pressure of the adjusting screwsis converted into a resilient pressure by the interposi- Vtioning of the screws 38. i This pressure can be regulated to suit the quality and thickness of the mop cloth and when it is desired to wring the mop cloth the same can be done by rotating theroller 19 through the'medium of the hand cra-nk 22 and since the mop cloth 31 is in the form of an endless loop, various parts of the cloth can be brought into mopping position so that the cloth will wear substantially equal at all points.

'While l have described myinvention as taking a particular form, it will be understood that the various parts ofniy invention may be changed without departing from the spirit thereof, and hence l do not limit myself to the precise construction set forth, but consider that l am at liberty to-make such changes and alterations as fairly come within the scope of the appended claims.`
