SPECIFICATION forming part of Letters Patent No. 762,252, dated June '7, 1904,

Application filed May 13, 1903,

To all whom it may concern:

Be it known that I, EDWIN PRESCOTT, a citizen of the United States, residing at Arlington, in the county of MiddleseX and State of Massachusetts, have invented an Improvement in Mop-Wringers, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

My invention consists in a new and improved mop-wringer of the typeemploying a pail provided with a pair of wringing-rollers having a relative movement toward each other and suitable mechanism for effecting necessary relative movement of the rollers.

My invention will be best understood from I the following description, taken in connection With the accompanying illustration of one specific embodimentthereof, while its scope will be more particularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a plan view of the described embodiment of my invention. Fig. 2 is a side elevation of the same, showing the rollers in their normal or separated position and the treadle in its elevated position. Fig.- 3 is a similar elevation showing the rollers in proximity and the treadle in its depressed position; and Fig. 4 is a sectional elevation on the lined 4, Fig. 1..

In the drawings, a is a water-holding receptacle, herein termed a pail, of any'suitable form, material, and size. I have herein shown the same as having a substantially rectangular cross-section with substantially vertical side walls, but with an inclined or undercut end wall, although this form and construction may be widely departed from. The pail is provided with a suitable bail or handle 6, pivotally secured to the overturned pail-rim, and is also provided with the substantially horizontal base-bail c, secured'near the bottom of the pail and projecting outwardly from the undercut front end thereof to give an extended base-support therefor and presenting supporting-surfaces, as the bail edge 0 and the underturned foot 0 beneath the level of the pail-bottom, to elevate the same from the floor or other support when in use. This maintains the pail-bottom clean and dry, and

Serial No. 156,964. (No model.)

since it relieves the bottom surface of all wear the corrosion ordinarily experienced with mop-wringers of this type, where the worn surface contacts with the alkaline solutions often employed, is prevented. A roller cl, which may be of wood or other suitable material and herein shown as stationary, is journaled in the overturned rim of the side walls near the pail-front, and the cooperating relatively movable roller e is journalcd in the yoke-shaped fulcrumed roller-carrier f, having its two bent or offset legs fulcrumed at g, about which it is adapted to swing to'bring thesaid roller 0 against the roller (Z, as shown in Fig. 3.

The base-bail 0 is curved upwardly at the sides of the pail to provide a firm support for the carrier-pivot at its fulcrum 9. Each leg 7 of the roller-carrier is connected at the opposite side of its fulcrum g through connectinglink IL with the end of the bent or angular leg of the fulcrumed yoke-shaped treadle-carrying member 2', which is normally held in a substantially horizontal position, as shown in Fig. 2, by the spring j, secured to the link it and one leg of the yoke to force the same apart and maintain the rollers in their separated positions. The yoke z' is fulcrumed upon the rod 70, extending through the overturned rim of the pail-top from one side to the other and above the usual water-level therein, and is provided with a treadle, as Z, by which it may be readily depressed from the position in Fig. 2 to that shown in Fig. 3

to throw the levers f forward and the rollers together.

Referring particularly have provided cooperating gathering members m, secured to the side pail-walls, extending forward with a slight downward inclination and presenting gathering-Walls diverging in both directions from the line of bite between the rollers. The rear ends of the gathering members are also in the appropriate location to provide additional bearings for the fulcrum-rod in to stiffen thereby the entire pail structure. The forward divergence of the gathering members is at such an angle that the lateral thrust against the same when the mop is squeezed between the rollers is to Figs. 1 and 4, I

taken up substantially lengthwise the said members or in a direction presenting the greatest resistance, and the structure is there.

by materially stiffened.

When the mop-wringer as above described is used, the pail is filled with water ordinarily to a level at or beneath that indicated in dotted lines in Figs. 2 and 3, and as the mop is about to be withdrawn from the water within the pail the treadle is depressed from the position shown in Fig. 2 to that indicated in Fig. 3 to force the roller 6 forward to pinch or squeeze the mop between the same and roller d as the same is withdrawn from the pail, the gathering members cooperating to gather the ends of the mop and deflect them toward the center.

In wringers of this type as heretofore constructed the depressed position of the treadle has been such as to apply the downward pressure thereon in a vertical line comparatively remote from the vertical line of the rollers, the upward pull upon the mop and the downward pressure upon the treadle producing a turning moment tending to upset the pail. It will be observed that in the embodiment of my invention herein shown the treadle Z, which has an initial position immediately in front of the roller d, is so fulcrumed as to have a movement downward .and inward under the undercut front pail-wall, having a final depressed position substantially beneath the rollers, thus bringing the downward pressure upon the treadle and the upward opposite pull upon the mop in substantially the same vertical line and preventing all tendency for the pail to overturn from this cause. By the inward and downward movement of the treadle the application of pressure thereto when in the depressed position is in a vertical line near the vertical line of the center of gravity of the pail, and the unstability of the pail is thereby reduced to a minimum, and its base-bail 0 may be correspondingly shortened. The extension of the fulcrum-rod is from one side wall of the pail to the other provides a firm fulcrumed support for the treadle adapted to resist the downward treadle-pressure. It will be further observed that by the bent form which is given to the legs of the fulcrumed carrier f such carrier, with its connecting-yoke above the roller 0, is so located to the rearward relatively to the roller as to avoid all interference with the mop-head when the treadle is depressed and the rollers are thrown forward. This condition will be noted by observing the position of the connectingyoke in Fig. 3, where it is almost vertically above the roller 0 instead of having in that position of the roller a location considerably to the front of its position there shown, which would be the case were the legs f straight and not inclined. By comparing the positions of the levers in Figs. 2 and 3 it will also be seen that the relative arrangement of the two fulcrums and the inclination of the two legs of the roller-carrierf and the treadle-carrier '5 gives a relatively increasing leverage for both roller-carrier f and treadle-carrier 41 during the operation of the treadle, and consequently an increasing leverage and decreasing roller movement of the entire lever system during operation.

It will be obvious that the specific embodiment which I have herein shown is for illustrative purposes only and that suitable modification of the details thereof, of the lever connections, the location of the respective fulcra, and the construction and relation between the respective parts may be made within wide limits without departing from the spirit of my invention.

I claim 1. A wringer comprising a pail having a flaring front end wall, a plurality of rollers one of which is positioned over said flaring wall and a roller-moving treadle for the other roller, said treadle being fulcrumed adjacent the top and rear corner of the pail whereby its depressing movement carries its foot-receiving portion from position beyond said flaring wall into a position under said wall and the roller positioned over the same.

2. A wringer comprising a pail having a flaring end wall, a plurality of rollers one of which'is fixedly positioned over said flaring wall and close-to the edge'of said pail, carrierarms for the other roller, said carrier-arms being fulcrumed near the bottom of said pail, a roller-moving treadle fulerumed near the top of said pail and at the side thereof which is opposite said flaring end wall whereby depression thereof carries its foot-receiving portion from position beyond said flaring wall into a position under said wall, and under said fixedly-positioned roller, said roller-carrying arms and said treadle having their ends respectivelyextended beyond their respective fulcra and connecting means operatively connecting said extended ends for the movingof said arms by said treadle, said carrying-arms between their fulcra and the pointsat which said roller is mounted therein being deflected from a straight line and having their ends connected by a connecting member arranged externally to said roller said connecting member being removed by the deviation in said arms, from the line of draft of the mop from between said rollers.

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

EDWVIN PRESCOTT.
