Be it knownthat I, SiMEoN C. LAwnoR a citizen'of tlieUnited States, residing at Chicago, inthe county of Cook and State of` Illinois'7 have invented Certain new and useful Improvements in Mop-VVringers; andI do hereby declare the-following to be a full,

clear,` and exactdescription of the invention.

such as will enable others skilled inthe art to which it appertains to Vmake and use the saine..

'Ihis linvention relates to wringers, particularly for mops, for use with pails or buckets into which the exuded fluid may be Y received.

An object is' to embodyiin a device of this character a stand or support which may be readilymoved from place to place over a floor,"and which may be anchored or heldfl froml movementv automatically upon the opA eration of the device to lwring a mop ;k and to.- provide the device with novelmeans for iii-` suring theA collection and diverting into the Y pail or bucket of the Huid eXuded from the mop and which may collect-upon the roller supports and adj acentparts of the device.

With these and further objects in view as will in part hereinafter become apparent and Y in part be stated, the invention comprises certain novel constructions, combinations and arrangements of'parts asfsubsequently specified and claimed. l

Referring to the drawings by numerals, i() indicates va pail or receptacle supportingk base which is preferably 4formed of a metal.V lic strap set on` edgel and reinforcedby cross straps' 11`.and.12 connectin-g opposite points of strap 1() and kforming the bottom orsupporting portion of the base upon which the pail or other receptacle 13l is designed to be sustained. The base l() is carried on casters 14 and 15 arranged in pairsnear the opposite mounted in ysuitable brackets 16 of strap metal which are riveted or otherwisesuitably secured to the opposite sides of the base l() near one end thereof, which end may be PATENT OFFICE. g

The, casters 14 are designated as the rear or inner end of Y base.

The casters l5 are mounted iii brackets 17 liavingfupstanding stems' 18 -journaled in supporting brackets 19 .of` preferablyy U-` shape and which embrace the adjacent side portionsof the base 10 andk havetheirfflanges prog'ecting inwardly' in vsuperposed relation to orm spaced supports for the stems 18. Thestems 18 are slidable vertically through;

f the. brackets 19 and 'arenormallyl urged downward by spr1ng's20 bearing at their upper ends beneaththe top flanges of the brackets 1,9 and being supported at their lower -endsupon washers or other suitable abutments 21' carried upon the stems `18above the lower flanges of the brackets .19. The washV` n ers 21 are' adapted to engage the lowergianges Vof the brackets 19 vand'limitv the downward thrust of the stems *18 formaintaining the .casters 15 in position onthe base-10 when the lattenis raised `from the floor. The casters 15 are mounted on the base 10 in spaced relai tion to the outer or front end thereonan'd mounted upon saidfront end, of the base 10 are one or more feet 22 formed prefer'ablyy of SOl strapy metal riveted or'iotherwise "suitably secured tothe strap forming the base' and de pending therefrom.V The lower. end of the i feet are turned inwardly to form flat engag ingportions which are spaced slightly above the floor when the base 10 supports its nor-v mal load,v and the springs 2i() vare proportionately tensioned to sustain the `feet`22 insu'ch elevated position at normaltimes. For as sisting in lowering the forward end ofthe base 10 and maintaining it from movement over thef'loor, foot pieces 23Vinay bel secured intermediately to the opposite sides-of the4 base 10, and maybe of similar construction- `tive slot.

facture, may consist ofastandard 24 and a standard '25 which aremerely continuations of the connecting straps 11 and 12 and which are riveted to the strapforming the base 10. The upper ends ofthe `standards 24 and 25 vare preferablyA laterally curved or bent to approach each other at the upper end of the side frame, andv are connected thereat by a plate 26 whichis riveted Vto` both standards. A'V cross bar or plate 27 connects the two top plates 26V and has its opposite ends riveted or otherwise suitably secured thereto. Each top plate 26 extends vertically above the respective standards 24 and 25 and is bent to a horizontal position across the upper edge thereof to form ajledge 28, and then again bent to an upstanding position to form a supporting and guide flange 29. The flanges 29 are slotted, as at 30, and the plate at the lower` edge of the slot isbent outwardly to form a broad trackway or support 31 for the re; ception of the adjacent trunnion 32 of the movable wringer roller 33. The flange 31` thus formed provides a relatively broad trackway adapted to 4resist wear, and provide a firm substantial supporting surface for the roller 33. The ledge 28 of each top plate 26 is provided with a longitudinally extending slot 34 for receiving and guiding an actuating arm hereinafter mentioned.

A bail-like leverv 35, forming a treadle, has its ends pivoted as at 36 to the standard' 25and its intermediate or closed portion upstanding over the forward end of the base 10 and provided with a suitably attached tread plate 37. Pivoted to the respective sides of the treadle 35,` intermediate the pivot point 36 and the tread plate 37, are the respective upstanding arms 38 which extend through and are guided by there- `spective slots 34, the slots being of a size loosely accommodating the arms but of suiliciently snug fit to prevent any excessive lateral or edgewise play. Each arm 38 is bent edgewise substantially midway of itslength for causing the upper end of each arm to travel laterally a greater distance than it would otherwise travel for the purposes hereinafter mentioned. It is to be noted also that the connection at the lower end of each arm 38 is spaced from the respective pivot 36 a distance sufficient for causing the lower end of each arm to always remain outside the vertical, transverse planes of the slots 34, so that each arm 38 extends on an incline longitudinally through the respec- A spring 39 is preferably arranged at each side of the frame with its upper end connected to the adj acent top plate 26 and its lower end connected to the treadle 35 for maintaining the treadle 35 in a normally raised position. A wringer roller 40 extends across from one side frame to the other and is journaled in the forward portions of the anges 29 of the top plates. A movable wringer roller 33 is journaled in ,the upper ends of the arms 38,` one of the journals of the roller 33 extending beyond the respectivearm and being provided with an operating crank 41. The journals 32 of each'movable roller preferably consist of a reduced shaft fixed to and outstanding from the ends of the roller, and may be connectedV in suitable manner to the arms 38 for holding the journals 32 from longitudinal movement through the arms. j n f While the wringer rollers 40 and 33 may be of any preferred type or construction,

it is preferable to construct the xed roller 40 with an uninterrupted smooth peripheral surface and to provide the movable wringer roller 33 with alternately arranged slots and circular openings, as shown in Vdetail in Figs. 6 and 7, to facilitate Vthe extraction of moisture from the mop without injury to.

the same.

VEach top plate 26 is provided in the ledge thereof with a drain opening or perforation 42 and a surrounding bead or raised portion 43 forming wall adapted to con-fine fluid dripping from the guide trap 31 and for directing the fluid to the drain opening 42. The connecting bar or plate 27 is preferably of sheet metal and is stamped substantially U-shape. The closed portion of the U- shaped plate27 is arranged between the forward ends of the top plates 26 and laps beneath the ledges 28 beyond the drain openings 42. Depressions or channels 44 .l are formed across the inner edge portions of the connecting plate 27 in line with the drain openings 42 and lead or open in a position over the pail or bucket 13 for Areturning the collected fluid thereto. The outer ends of the channels 44 are closed as shown in Fig. 5. To enable the easy carrying or transporting ofv the device from place to place, a handle or bail45 is ,piv-

oted at a suitable point upon the upstanding flanges 29 of the top plates, and is adapted to be swung forwardly" into a position out of the Way, as shown in Figs. 1

and 2, when it is desired to wring mops.

For the purpose of reinforcing the base frame 10'and maintainingthe cross` straps 11 and 12 rigid, a brace strap 46 may be employed and is secured across the under sides of the cross straps 11 and 12 midway between the sides of the frame 10. The brace strap 46 has at its forward end an upturned lip 47 adapted to assist in centering the receptacle 13 upon the straps 11 and 12, and

hasatitsrearf end:` a. depending; foot-:48 terminatinm in `1I1Q11I1a11y; spaced relation from the'flborA andxbeing ada tedto arrest 48: a.` more stable device is Vprovided than in prior structures asf-theslighttiilting which may be effected before` the. foot 48 strikes the ground is not sufficient to dislodge the receptacle 13 or spill the fluida-:contents thereof. n

In use, the device may be lifted: and carried by the handle or bail 45 and may be pushed or pulled over the floor to the desired location for use. When it is desired to wring a mop the user may place one foot upon the adjacent foot piece 23 to depressV the forward end of the base 10 and bring the feet 22 and pieces 23 into contact with the floor, thus anchoring or maintaining the base 10 from movement. The mop is placed between the rollers 33 and 40, the treadle 35 is depressed by the other foot to bind the mop between the rollers, `and the roller 33 is turned as by the crank handle 41.

The foot pieces 23 stand out from the base 10 in convenient position to receive the ball of the foot in the natural position assumed when the user stands close to the device. As both the feet 22 and the foot pieces may, though not necessarily so, bear against the floor the base is securely maintained against accidental movement under pressure upon the'hand crank 41 or pressure upon other parts of the device.

Either foot whenengaging the respective foot piece is in natural position for supporting the operator when applying' the other foot to the treadle 35, pressure on the treadle further insuring the stability of the baselO.

The fluid exuded from the mop is deflected by the upstanding flanges 29 from the fixed roller 40 upon the connecting bar 27 and back into the receptacle 13. However, usually the fluid which drops from the ends of the movable roller 33 and from the trunnions 32 thereof frequently passes out through the guide slots 30 and over the trackways 31, dropping upon the ledges 28 outside of the flanges 29 and falling outside of the receptacle upon the floor. With the present construction the fluid escaping through the slots 30 and over the trackways 31 falls upon the ledges 28 but within the wall or ridge 43. The fluid is thus trapped against the outer sides of the flanges 29 and escapes through the drain openings 42 and channels 44 back into the receptacle 13.

Immediately pressure is relieved from the base 10, the springs 2() raise the floor confacts out of engagement with the floor, and

the device may then be easily shifted to any new position desired., Preferably, the casters lare swiveled upon theirstemslS sothat the. Vbase 10may be easilyturned and ma-f ,nipulatedt i f' 1,;
