In the form of the invention illustrated in the drawings of this application, the mop and wringer comprises a mop unit indicated generally at iii, a handle indicated at 2 attached to said mop unit and a compression or wringer device indicated at I4.

. The mop unit includes a backing plate It and a mass 58 of absorbent compressible material secured to said backing plate at the bottom thereof. The backing plate 55 extends transversely of the directions of normal mopping movement and has upper and lower faces and front and rear edges. The absorbent material is preferably consists of a rectangular prismatic block of cellulose sponge mounted in a shallow channel or trough in the backing plate it formed by the narrow flanges 2 0 and 22 on the plate bent at right angles to the body of the plate. The block of sponge is securely attached to the backing plate by a suitable cement and it extends from end to end of the said plate.

The handle of the mop comprises a body portion or shaft 24 which may be made of wood, and a hollow socket 26 preferably made of sheet metal in which the lower end of the shaft 24 is secured.

The handle is attached to the mop unit to extend upwardly and rearwardly therefrom at an angle of about 45 to the upper face of the backing plate, as clearly shown in Fig. 1. The handle is attached to the mop unit by securing the lower end of the socket 25 (Fig. l) of the handle detachably to the said backing plate E6.

The compression device comprises a pressure or wringer member shiftably connected with the backing plate and arranged to be moved from an inoperative position relatively remote from the mass 18 of compressible material into engagement with said mass thereby cause the discharge of water or other liquid therefrom. This pressure member, in the preferred form of the invention illustrated in this case, includes a compressor plate 28 of rectangular form corresponding with the form of the lower face of the block is of compressible material and made of sheet metal. The plate is shown as provided with a series of holes 30 through which some of the liquid squeezed from the mass :8 may be discharged. The plate is mounted in a frame 32 consisting of a cylindrical metallic rod bent in rectangular form corresponding in dimensions to the dimensions of the plate 28. The plate is shown as connected with the bent rod frame by marginal extensions as on the ends and one side of the plate bent about the corresponding parts of said frame.

The pressure or wringer member is hingedly or pivotally connected to the backing plate so that it may be swung from the inoperative position shown in Fig. l to operative or compressing po-- sition with relation to the mass l8. To this end, the rod which forms the frame 32 of said member is provided with offset arms 36 and 38 extending obliquely away from the edge of the main portion of the compressor plate nearer the backing plate and also downwardly (Fig. l) in a direction oblique to the plane of said compressor plate, and with inwardly bent axially aligned end pintles Gil and d2 substantially parallel with the portion of said frame more remote from the mop unit, each pintle all and 42 forming one element of a hinge. These pintles are constructed and arranged to engage respectively in corresponding tubular hinge elements or members 114 and 46 formed on a second or attaching plate 48 preferably made of sheet metal and fixed to the backing plate 16. This second or attaching plate has the form or outline shown inFigs. 2 and 7 and the hinge elements 44 and 4B are produced by bending into tubular form portions of the projections 49 extending from said plate.

The rod which forms the bent rod frame for the pressure plate 28 is provided with an extension 50 forming a loop having substantially parallel sides extending, in general, at right angles to the portions of the rectangular frame of the compressor plate more remote from the mop unit and the hinge axis. This extension constitutes a handle for the compressor plate by which the same may an upper rear inoperative position adjacent and below the handle as shown in Fig. 1 to an operative position in compressing engagement with the compressible mass l8 as shown in Fig. 4 and from the said operative position back to the said inoperative position.

In moving from the said inoperative position to the said operative position, the compressor plate moves downwardly and forwardly and upwardly, and it first engages the sponge block 18 at the lower rear edge or corner thereof and it then progressively compresses the said block from rear to front so that the major portion of the water or other liquid is forced forwardly and is expelled at the front. By means of the offset arms 36 and 38 the said compressor plate, when in its final compressing position as shown in Fig. 4, is offset downwardly from the second plate M3 by a distance substantially less than the initial vertical thickness of the sponge block i8. This offset enables the compressor plate to press the to compress the same and be readily shifted from sp nee.-blockl-,.tol the. requiitediesteat-buir tendstto.

these parts in assembled relation when the mopis completely assembled.

In assembling the attaching plate 48 and the compression device, these parts are placed in the relative positions shown in Fig. 7 with the hinge elements 40 and 42 on the compression device respectively in axial alignment with the hinge elements 44 and 46 on the attaching plate and with the hinge elements and the parts adjacent the hinge elements on the compression device and theattaching plate respectively in the relative angular positions shown in Fig. 13 and the attaching plate and compression device are relatively manipulated to shift the compression device with relation to the attaching plate axially of the hinge elements in the direction of the arrow, Fig. 7.

To enable the hinge element 42 to telescope within the tubular hinge element 46 during this relative movement of the parts, the portion 38 of the bent rod frame at or adjacent the hinge element 42 is formed with a crease or groove 16 (see Fig. 13) to receive the margin 12 of the hinge element 46. Thus, with the parts in the angular positions shown in Fig. 13, during the relative movement of the compression device and the attaching plate to shift the said device in the direction of the arrow, Fig. '7, with relation to said plate, the groove 10 allows the hinge member 42 to be engaged in the tubular hinge member 46, the margin 12 of the latter member passing through said groove during the said relative movement of the compression device and the attaching plate. Fig. 8 shows the attaching plate and the compression device after having been moved relatively axially of the hinge elements from the position shown in Fig. 7 part way to final assembled relation, the margin 12 of the hinge member 46 then engaging in the groove I6 in the portion 38 of the bent rod frame. Fig. 9 shows the attaching plate and compression device after having been moved to their final relative axial positions by the continued relative movement axially of these parts to shift the compression device'with relation to the attaching plate in the direction of the arrow, Fig. 7, from the position shown in Fig. 8.

Thus the attaching plate and compression device may be quickly and easily assembled by a simple readily executed relative manipulation of these parts.

The present construction comprises means for preventing the compression device and attaching plate from being moved relatively to locate the hinge members. 42 and 46 in the relative angular positions shown in Fig. 13 when the head, compression device and handle of the mop are assembled and secured together in operative relations.

As indicated above, when the compression device is swung into fully retracted position as shown in Fig. 1, its movement is limited by the engagement of the outer portion of the handle 56 of said device with the shaft 24 of the mop handle as shown in Figs. 1 and 6. With the compression device in this position the hinge members s2 and 46 and the parts of the bent rod frame and attaching plate adjacent said hinge members are located in the relative angular positions shown in Fig. 11. When the compression device occupies this position, said device is prevented from being shifted axially in a direction opposite to that indicated by the arrow, Fig. 7, with relation to the attaching plate, to disassemble the compression device and attaching plate, by the engagement of the marginal portion 12 of the hinge member 46 with the arm 38 of the bent rod frame. The mop handle therefore locks the compression device from being swung into a position in which it may be disassembled from the attaching plate.

If it is desired to disassemble the compression device from the attaching plate for the purpose of repair or the substitution of parts, the mop handle is detached from the mop and the compression device then may be swung into position to locate the hinge members 42 and 46 and the parts of the attaching plate and the compression device adjacent said hinge members in the relative positions shown in Fig. relative positions shown in this figure, the compression device may be detached from the attaching plate by relatively manipulating the compression device and plate to shift the compression device in a direction opposite to that indicated by the arrow, Fig. 7.

When the compression device is swung from the retracted position shown in Fig. 1 toward or into operative position the arm 38 of the bent rod frame assumes positions such as those indicated in dot-and-dash lines in Fig. 11. When the compression device occupies one of these positions, said device is prevented from being shifted axially in a direction opposite to that indicated by the arrow, Fig. 7, with relation to the attaching plate by the engagement of the arm 38 of the bent rod frame with the adjacent edge of the hinge member 46. When the compression device is in any angular position with relation to the attaching plate, relative movement of the compression device and the attaching plate to.

shift the compression device in the direction of the arrow, Fig. 7, is prevented by the engagement of the arm 36 of the bent rod frame with the adjacent edge of the hinge member 44.
