MOP WRIN'GER.

Application filed February 16, 1921. Serial No. 445,332.

.York, have invented a certain new and useful Improvement in Mop vVringers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in mop wringers shown in the accompanying drawings and more particularly described in the following specification and claims.

This invention has for its object an improvement in mop wringers designed to be supported upon the wall of a pail, having a swinging and a stationary pressureboard between which the mop is placed to express the water from the latter;-the working parts being formed of sheet metal by forming dies thereby materially reducing the cost of manufacture and the time required for assembling the parts.

A further object of the invention is to provide means for directing the water expressed from the mop into the pail on which the wringer is supported, thus overcoming the objections to devices of this type wherein the dirty water from the mop is frequently ejected through the unguarded apertures in the presser-boards onto the clothing of the operator or onto the floor surrounding the ail.

p A still further object of the invention is to so shape the sheet metal wall of the swinging presser-board that brackets are provided integral therewith to support the floorboard which is also an integral part of the presser-board.

A further object of the invention is to provide a construction wherein the pressure exerted by the toggle mechanism is exerted directly against the presser-board, or against a reinforcing strip attached theretowhe reby the pivot pins forming the connectlon between the toggle-mechanism and the presserboard are relieved of the shearing strain that would otherwise be exerted upon the pins themselves when manually operating the device to express the water from the mop.

A further object of the invention is to provide the overhanging hook straddling the pail with a relatively broad surface to bear upon the wall of the pail on one side and with a like broad bearing surface at the lower end of the leg to engage the opposite side of the pail, whereby the pressure exerted in operating the device will be distributed that it may not injure the pail.

A further object of the invention is to provide a suitable supporting hub for the springs which serve to normally maintain the pressure boards in spaced relation to each other to receive the mop,-the hub being struck-up or shaped out of the body of the metal forming the walls of the presserboards.

With the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the device herein disclosed without departing from the spirit of the invention.

In the drawings accompanying this specification:

Figure 1 is a perspective view of the mop wringer with a portion of the manually operated lever broken away.

Figure 2 is a vertical cross-sectional view through the device taken on or about line 2-2 of Fig. 1, the wringer being suspended upon the wall of the pail-a fragment of which is shown.

Figure 3 is a perspective view of the wringer viewed from the side opposite to that shown in Figure 1 and with a portion of its end wall broken away to more clearly disclose the toggle lever mechanism attached to the swinging presser-board.

Figure 4 is a horizontal cross-sectional view through the wringer taken on or about line 4:4: of Fig. 2, looking downwardly toward the floor board of the swinging arm, a portion of the floor-board being broken away to disclose one of the brackets integral with the side walls of the presserboard for supporting the floor-board.

Figure 5 is a View of the blank form from which the stationary presser-board is formed, the dotted lines indicating the point at which the blank is bent to form the sides, end wall, and other integral parts of the device. I

Figure 6 is a view of the blank'from which the swinging presser-board is formed showing in dot ed lines the point at which the blank is bent to form the end, side walls and floor board of the device and also the brackets which support the latter.

Figure 7 is a sectional view of a detail showing the manner of supporting the springs upon abutting hubs formed on the stationary and swinging side walls of the resser-board.

Figure 8 is a detail view showing a portion of the toggle lever mechanism pivoted to the swinging presser board, the pivot pin being relatively small as compared with the aperture in the lever through which it projects in order that the end of the toggle lever may exert its pressure directly against the cleat attached to the presser board, thereby relieving the pin of any shearing strain which would result if the pressure of the toggle lever mechanism were brought to bear directly upon the pivot pins.

Referring now to the letters of reference placed upon the drawings:

A, denotes a stationary frame of sheet metal, of. U-shaped form in horizontal crosssection, having legs A extending. downwardly into the pail provided with relatively broad inwardly directed ends A adapted to bear against the wall of the pail. A indicates relatively short depending legs spaced from the legs A to receive the wall of the pail B;the legs A having inwardly directed flanges A, to providea broad bearing surface engaging the outer wall of the pai A is a relatively narrow slot formed in the side wall of the device stepped from the broader slot below to adapt the device for suspension upon either a metal or wooden pail B.

A indicates a vertical ribv formed in the leg A to stiffen the latter. A are apertures in the wall of the presser board having an overhanging portion A to direct the water discharged through the apertures downwardly into the pail.

C, denotes a swinging pressenboard also constructed of sheet metalby suitable forniing dies, having relatively narrow side walls C with depending legs C pivoted by a bolt D to the depending legs A of the stationary presser-board.

The legs A of the stationary presserboard and the legs C of the swinging presserboard are each respectively formed with opposing hubs A", and C around which are coiled springs E, their ends respectively bearing against a flange or lip A formed on the stationary leg and a like flange or lip C formed upon the swinging legthe action of the springs serving to maintain the presser-boards in an open or spaced relation to each other to receive the mop. The swinging presser-board C is also provided with a floor board. C bent at substantially right angles to the imperforated pressure back C", the floor board however being perforated as at c, that the water expressed from the mop may be discharged into the pail. v

C are, brackets bent inwardly from the depending legs C to serve as a support for.

the outer end of the floor board C.

D? is a rock-shaft journaled in the side walls of the frame A, provided with rocker. arms D D", to which are connected toggle.

levers D D, in turn pivoted to a cleat F riveted to the movable resser-board C. The end of the toggle lever bears directly upon the cleat-the aperture in the toggle lever bein sufliciently large to relieve the pivot pin connecting the toggle lever with the swinging presser-board of any shearing action that might occur if the pressure result.- ing from the operation of the device were brought to bear directly upon the pivot pins instead of the cleat attached to the presserboard.

H indicates a lever attached to the end of the rock shaft D for manually operating the device. v

Having indicated the several parts'by reference letters the construction and operation of the device will be readily understood.

To wring the mop it is placed between the presser-boards,the manually operated lever is then actuated forcing the movable board toward the stationary presser-boaid thereby expressing the water out of the mop through the perforations, whereupon the overhanging portions of the latter will direct the water into the pail below.

Having thus described my invention What I claim is:

1. A mop wringer comprising a swinging and a stationary frame pivot-ally connected at the lower ends thereof, a rock shaft journaled in the stationary frame having rocker arms integral therewith, toggle levers pivoted to the rocker arms and swinging frame having openings at their ends, a bearingv plate for, the toggle levers secured to the swinging frame and having flanges thereon, studs carried by the flanges and adapted to fit loosely within the openings in the toggle levers whereby the toggle levers contact directly with the bearing plate and the said studs are relieved of shearing strain due to the operation of the swinging frame.

2. A mop wringerv comprising a stationary and a swinging presser-board formed of sheet metal, a floor board integral with one of the said presser-boards, integral extensions on each board and brackets formed on the extensions of one of the boards and bent at an angle thereto to lie beneath the floor board and support the same and means for operating the swinging resser-hoard.

In testimony whereof, I sign this specification in the presence of two Witnesses.
