Specification of Letters Patent.

Patented my 10, 1906.

Application filed March 8, 1905. Serial No. 249,131.

To all whom it may concern:

Be it known that I, MATHEW TIMOTHY, a citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented a new and useful Improvement in Mop-l/Vringers, of which the following specification, taken in connection with the drawings accompanying the same,is a description which will enable others skilled in the art to which my invention appertains to make and use the same.

My invention relates to mop wringers which maybe placed upon the top of abucket or other vessel for holding water; and its objects are to provide a mop-wringer of simple construction which may be used in conjunction with a bucket Without requiring any mechanical fastenings thereto and in which the expressing-rollers may be adjusted to the desired juxtaposition and so retained.

Further objects will be obvious from the following description.

In the drawings, Figure 1 is a side elevation of a bucket with my improved mopwringer mounted thereon, in which the adjustable roller is raised to permit the insertion of the mop, into the bucket. Fig. 2 is a similar view in which the adjustable roller is shown in juxtaposition with the stationary roller, with the mop (in dotted lines) shown therebetween for the purpose of being squeezed by said rollers and having the water expressed therefrom. Fig. 3 is a plan view of a bucket and my invention mounted thereon, with the rollers in the position shown in Fig. 2. Fig. 4 is a plan view of the frame adapted to rest on the top edge of the bucket and upon which the operating parts of my invention are mounted. Fig. 5 is a detail view of one of the springs, one of which is secured to each end of the supporting-frame, their free ends supporting the lower roller and supplying the necessary resiliency to accommodate the expressing-rollers to any unevenness or irregularity of the mop which is to be wrung out.

1 represents the bucket, 2 the supportingframe, which preferably will be formed of a part circle having a cross-bar and may have one or more downwardlyrojecting ears to prevent its displacement y lateral movement. One of such projections is shown at a, Figs. 1 and 2. Near the center of such supporting-frame and made integral with the cross-bar of the supporting-frame are two upwardly-extending ears I) b, upon and between which is fulcrurned the forked roller arm 3. Between and upon the extremities of the arms 0 c of the roller-arm 3 ,is revolubly mounted the shaft 4, which carries the upper roller 5. The rear portion d of the roller-ar n .3 is engaged by the earn 6. This cam is sub.-

stantially of disk form, is centrally perforated, and is mounted upon the rear portion of the supporting-frame by means of a bolt and nut or by any other Well-known means, so as to be revoluble in a horizontal plane upon such bolt-bearing; Said cam is provided with a space or slot e to permit the passage of the extremity of the portion (Z of the roller-arm 3 therethrough and a handle f for the purpose hereinafter explained and a raised rim which is thinnest at a point adjacent to said slot and which inclines gradually and uniformly around said disk, being thickest or highest at the opposite side of said space or slot.

7 7 are springs which are firmly secured to the supporting-frame near the extremities thereof in any well-known manner, their free ends being bent so as toform a bearing in which the shaft 8, carrying the lower roller 9, is revolubly mounted. To one of the extremities of the shaft 8 I secure a crank 10, provided with the usual handle.

In practical use my improved mopwringer is placed upon the top of a bucket containing water or'other desired cleansing element, so that the supporting-frame rests upon the top edge of the bucket. The cam is then revolved so that the space e therethrough will stand parallel and in line With the extension at of the forked roller-arm 3. The extension (1 is then depressed, its extremity passing through the space 6, and the rollerarm 3 is swung in its fulcrum-bearing in the ears I) b, causing the upper roller 5 to be elevated, as shown in Fig. 1. The mop is then dropped into the bucket of water and is withdrawn so that it rests on the lower roller 9, as shown by the dotted lines in Fig. 1. The upper roller is then pushed down until it bears against the mop. This will cause the extension (2 to be raised through the space 0 of the cam, and by grasping the handle and turning the cam in the direction of t e arrow in Fig. 3 the inclined rim or rail on the cam will bear against the under side of said extension d, and as the cam is turned farther the gradually-inclining rim will exert increasing pressure on the under side of said extension (1, and, the roller-arm 3 being fulcrumed as described, the upper roller 5 will by this operalower roller 9 through the medium of the crank 10 the mop maybe wrung out, the water falling back 1nto the bucket. The lower roller being mounted on the springs 7 7, it

will be seen that any unevennessor irregularity in size of the mop will not afiect the easy operation of my improved wringer. The upper roller 5 may be released by simply turnmg the cam back to its former position and either depressing the extension d through the space a or raising said upper roller.

Having now fully described my invention, I claim as new and desire to secure by Letters Patent 1'. A mop wringer comprising a frame adapted to rest upon the to of a vessel for holding water,a roller-arm fu crumed in bearings'upon said frame one end of the arm being forked, its other end extending rearwardly, a roller revolubly mounted in the forked end of said arm, a disk having a slot therethrough and an inclined rim, to engage the rearwardly-extending portion of said roller-arm for the pur ose of de ressing said roller, springs secure upon sai frame, their free ends forming shaft-bearings, a shaft carrying a roller revolubly mounted in said spring-bearings, and means for'rotating said last-namedshaftand roller for the purposes herein stated.

2. In a mop-wringer, a frame adapted to rest upon the top of a fluid-holding vessel, the roller-arm 3 mounted thereon, the roller 5 mounted in the forked end of said roller-arm, v

the cam 6. mounted on the rear of the supporting-frame and adapted to engage the under side of the rear extension of said rollerarm, the springs 7, 7, secured upon the forward ends of the frame, the roller 9 mounted in the free ends of the springs, and means for revolving the roller 9, all for the purposes stated and substantially as described.
