Referring to the drawings, particularly Figs. 1 to 4, a pail 20 is shown adapted to contain wash water, the same having a vertical wall or partition 20a. While pail 20 could be of various forms, in the embodiment of the invention illustrated it is shown as rectangular in plan. A frame member 2l is shown comprising parallel vertical plates 2|a each having a slot 2lb adjacent one side in kwhich the upper portion of Wall or partition 20a 50 is disposed so that said frame is supported on saidrwall or partition. Plates 2| have their sides converging toward their lower ends and the same are provided with projections 2| c at their bottoms vertically alined with slot 2lb and adapted 525 f wardly over the upper ends of arms 26.

to engage the side of wall or partition a. Said plates at one side and at some distance from the top are connected by a transverse plate 22 which extends along one edge of plates 2l and then extends substantially horizontally across plates 2 la. Plates 2| and 22 are provided with a plurality of drain holes 2lf. Plates 2Ia adjacent said edge and above plate 22 are provided with a plurality of holes 2Id through any alined pair of which a headed rod 23 may be passed to extend between said plates. A plate 24, forming in effect a portion of plate 22, has its upper end bent into cylindrical form and adapted to have rod 23 pass therethrough so that it is supported on said rod and extends downwardly along the inner side of plate 22. Plate 24 can thus be supported at different heights and its upper edge will be disposed at different heights. Plates 2Ia each have an arcuate slot Zie in their upper portions, which slot is concentric with the center of pivot rivets or bolts 25 in the lower part of said plates. Links or arms 26 are secured at their lower ends to pivots 25 respectively and extend upwardly inside of and closely adjacent plates 2Ia, the saine passing between the sides of the horizontal portion of plate 22 and plates Zia. Arms 2B are connected by pivot members 21, which may be bolts or rivets, to lever arms 28, said pivot members 21 passing through the slots 21e and'levers 28 being disposed at the outer sides of plates 2la. Arms 26 have secured thereto along their sides adjacent plate 22 a flat plate 29 which extends from adjacent the horizontal portion of plate 22 upwardly and has its upper end curved rear- Lever arms 2S as shown in Fig. 4 are bent to extend toward each other and are then bent to have portions 28a extending in spaced parallel relation. Another arm 3U is disposed between portions 28a, being pivotally connected to the same adjacent its lower end by a pivot rivet 3| having thin washers thereon at either side of arm 30. Arm 36 and portions 28a have a plurality of alined holes 36a through one set of which extends a wooden pin 32. Lever 30 and portions 28a are thus connected'for simultaneous movement. The upper end of arm 36 is provided in one edge with a plurality of spaced recesses 33h. `In Fig. 3 a mo-p 33 is shown carriedat the lower end of a handle or mop stick 34. A member is adapted to be secured to mop stick 34 and the same has at its sides flat narrow projections 35h rectangular in cross section and adapted to be received in the recesses30b. Member 35 comprises a pair of oppositely formed strips or short bars 35a having central portions adapted to embrace mop stick 34 and having engaging portions at one side thereof connected by a rivet 35e. At the other side of mop stick 34 portions 35a, are separatedand connected by a headed stud 35d having thereon a wing nut 35e, portions 35a being somewhat resilient. Member 35 can thus be loosened by means of nut 35e moved along stick 34 as desired and clamped in the desired position thereon. The other ends of levers 28 are provided with a plurality of spaced holes 28h through any one of which a stud 36 may 4pass having its Vhead countersunk into said lever. Short bars 31 are secured to the outer sides of plates 25a adjacent one side'thereof and the same are providedlwith a plurality of spaced holes 31a. I'he holes 28h and 31a can be brought into alinement in pairs and studs 36 extend through one of the alined pairs, said studs being provided withwing nuts 385- It will be seen that levers 28 together with members 31 form a toggle lever and that this toggle lever may be varied by positioning stud 36 in diierent pairs of said holes so that plate 29 will be nearer to or farther from plate 22 when the toggle is straightened.

In Figs. 8 to 9 a modication is shown in which a plate 40 is used instead of plates 22.' and 24. Plate 4l) extends between and connects plates 4l which are quite similar to plates 2la Aalready described. Plate 40 has several transverse slots 40a formed therein, the metal from said slots being turned outwardly and downwardly. Plate 42 which is similar to plate 29 has transversely alined and vertically spaced pairs of slots 42a, therein, which pairs are substantially alined vertically with the slots 40a. A plate 43 is provided forming a bottom plate and the same has lugs 43a adapted to extend through a pair of the slots 42a. A bail rod 44 has its ends bent at right angles and adapted to extend through holes 43h in the lugs 43a, said bail being disposed at the opposite side of plate 42 from the main portion of plate 43. Plate 43 is thus detachably connectedA to plate 42 and may be connected to plate 42 at different heights. Plate 43 extends` through one of the slots 46a as shown and moves through said slot when plates 46 and 42 are relatively moved. Plate 42 is carried by arms pivoted to pivots 46 in the bottom of plates 4I. Plates 4l have slots lila, similar to slots 2lb and have the lower projections 4H) similar to projections 2Ic. Plates 4l also have inwardly projecting short lugs 4lc to which are fastened one end of springs 41, the other ends being fastened to studs 48 on arms 45. Springs 41 are so arranged that plate 42 will normally be held in its position separated from plate 46 and said springs will be extended when plate 42 is moved toward plate 40. Springs 41 may also be compressed by moving plate 42 to its rearward'limit of movement. Lever members 28 and 31 are provided as already described. Plate 43 is provided with a plurality of drain slots 43e. A bar 50 is secured to levers 28 in the same manner that bar 36 is secured and extends upwardly from levers 28. Bar 56 has secured to its upper end by a rivet 5I and extending at right angles therefrom a bar 52, the same having its end bent into substantially semi-circular form. A piece of flexible tough material 53 such as leather is secured at one side of bar 52 by a rivet 54, said piece extending around the end of said bar and into the bight thereof and having its other end secured to the opposite side of bar 52 by rivet 54; The mop stick 34 is adapted to be received in the fold or bight of the mate-- rial 53 as shown in Figs. 17 and 18.

In operation of the structure shown in Figs. l to '7, the device will be placed in the pail as shown, which pail will contain the wash water. Plate 24 will be adjusted as desired by placement of rod 23 in the desired pair of holes 2Id. If a heavy or large mop is being used said plate will be at one of its upper positions, while if a lighter or smaller mop is being used it may be in one of its lower positions as shown in Figs.1 to 3. 'Ihe lever bar 3D will be moved to bring the plates into the position shown in Fig. 2; The mop to be squeezed is theninserted downwardly between plates 24 and 29. vThe operator will previously have placed member 35 on the mop stick and fastened it in the desired position. After the mop has been placed between'the plates the operator will swing the mop stick-to the kleft as shown in Figs. l to 3 75 and one of the projections 35h will engage -bar 35 in one of the recesses 35h and said bar will be swung to the left with the mop stick. This movement swings levers 28 and the toggle formed by the same and members 3l is straightened. This causes arms 26 and plate 29 to be swung toward plates 22 and 24 and the mop is squeezed between these plates. The water squeezed from the mop will pass through holes 21j and around the sides of the horizontal portion of plate 22, said water thus draining back in the pail. The mop stick can then be swung to the right as shown in Figs. 1 to 3 and lever bar 35 moved to the right. The mop can then be readily removed from between plates 24 and 29. The pin 32 is provided so that if excessive pressure should be exerted on the mop said pin will be broken and there will be no damage to the mop or apparatus. Pin 32 can be placed in different sets of the holes 35a so that different breaking pressures may be had.

In the operation of the structure shown in Figs. 8 to 10 and 17 and 18 the plate L33 will be adjusted according to the weight or size of the mop. If the mop is a heavy or large one said plate will be placed in its lowest position. In this structure the plates are held in separated position by springs 4l. The operator places the mopdownwardly between plates l5 and lli. and then swings the mop stick to the left as shown in Fig. 8. The mop stick engages in material 53 in bar 52 and bar D together with levers 28 are swung to the left. This straightens the toggle and plate 52 is moved toward plate l5 so that the mop is squeezed between said plates. The water can drain through slots 3c as well as through slots 55a. When the pressure is relieved on the mop stick springs lll will separate the plates and the mop can be removed.

In Figs. 11 to 16 a pail 2D is shown and a frame member 55 is illustrated having side plates 55a with slots 55h therein forming tongues or hooks 55e. The side members 55a can thus be disposed on the side or partition 2Go, the latter extending into slots 55h and the tongues 55o being disposed at one side of said side or partition while the main portion of side plates 55a have their edges extending along the other side oi said side or partition. Plates 55a are shown as having a projecting portion 55d at their lower ends engaging said side or partition 25a. Side plates 55a have holes 55j extending therethrough. Frame 55 has a portion 55e of plate-like form, extending between side plates 55a, which side plates extend in parallel relation adjacent the sides of the pail 20. Plate 55e extends downwardly into pail 20 extending outwardly at a greater angle adjacent its upper end and at its lower portion extending substantially horizontally and to a point slightly beyond the plane of the vertical edges of side portions 55a. The side plates 55a adjacent one upper corner have a plurality of holes 55g therethrough and small headed and nutted bolts 55 are provided adapted to extend therethrough and through one end of a pair of links 51. The other ends of links 5l' are pivotally connected by rivet pivots 58 to the ends of bars 59, having their lower ends extending in parallel relation and other portions 59a converging and then extending in parallel relation along opposite sides respectively of a bar 55 extending above the frame 55. The parallel portions 59a have elongated slots 59h formed therein, and headed and nuttedbolts 6| pass respectively through these slots and through the bar 55. The parallel parts of the portions 59a are of angular formation as shown in Figs. 13 and 16 and have riveted thereto a plate 62. Plate 62 as shown has ribs 62a struck up therein and this plate extends substantially to the lower parallel portions of bars 59. A plate 63 is provided, extending between side plates 55a, which plate has secured thereto bars 5t extending along the inner sides of side plates 55a and pivoted thereto respectively by the rivets or bolt pivots 55. Bars 66 extend slightly above the top of plate 53 and are pivoted at their upper ends to the outer sides of the lower parallel portions of bars 55 by the rivets or bolts 65. The bar {il} extends upwardly above the tops oi bars 59 and plate 62 and is then oiset and has secured thereto a block 6l by the rivets 51a. Block El has a concave groove in the side adjacent plate 52 and is preferably covered with a layer G9 of some soft or yielding material such as leather. As shown in Fig. 1li, the side of block 5l adjacent bar 6i! is formed on a convex curve about a horizontal axis. It will be noted that the upper end of bar 55 is bent at right angles as shown in Figs. 11 and 12, as well as being offset laterally. A compression coil spring 58 surrounds bar 55, bearing at one end against the out-turned portion of bar 55 and at its other end against the top of plate 52. This spring normally holds bar Sil in position with the nuts 6I substantially midway of the slots 55h.

In operation, when the mop is to be squeezed, it is placed between the plates 63 and 55e in the position which they occupy in Fig. l1. The operator then places the mop stick l2 in the groove in the block 61 as indicated in dotted lines in Figs. 11 to 14 and swings the mop stick to the left as shown in Fig. 1l. This movement swings plate 53 about the pivot 55 and said plate approaches plate 55e. The mop is squeezed between these plates and the water therefrom runs downward under plate 53 into the pail as well as through the holes 55] into the pail. It will be noted that as the mop stick @l2 and bar 5U are swung to the left, the lower portions of bars 59 and the links 5l act to form a toggle which is being straightened. There is an increasing leverage, therefore, on the plate 53 as it approaches plate 55e. After the mop is thus squeezed between plates 53 and 55e, the operator can swing the mop stick again to the right and quickly move the same from engagement with block 51. The mop stick i2 is held in proper engagement with the block 15's' and need engage only a small portion of the surface of the soft or yielding member 69. Said member 5l can move vertically upwardly or downwardly within the limit of travel of plate El in the slots 5919. Should it be moved downwardly, it will be returned to normal position by the spring ES and if moved upwardly, will return to normal position by gravity. It will be noted that the increased angle of the flare on plate 55e accommodates the movement of the mop as the plates come to mop squeezing position.

From the above description it is seen that applicant has provided a simple and yet very efficient structure of mop squeezing apparatus. It will be seen that the pressure on the mop increases as the mop stick is swung to the left as described. An easy and convenient arrangement is had for exerting the desired pressure on the mop. It will also be seen that by moving member 35 thatmore or less leverage is obtained in moving or swinging bar 35. The apparatus is adapted to be removably supported in a pail as shown, or it may be permanently secured in a pail. The parts are comparatively few in number and can be strongly and ruggedly made.

It. is

obvious that the device will have a high degree of utility for the purpose intended.

This application is a division of applicants copending application S. N. 657,956, i'lled February 23, 1933, which has matured into Patent No. 2,049,619.
