9 Claims.

My invention relates to the class of devices which are employed for extracting water from mops and similar articles by a 'wringing operation.'v and an object of my invention, among others, is the production of a wringer for such purpose that shall be simple in construction and particularly eflicient in operation.

One form of a wringer embodying my inven- `ltion and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawings in which- Figure 1 is a side View of my improved wringer illustrating the manner. of clamping a mop therein.

Figure 2 is an end view of a mop showingmy improved wringer attached thereto preparatory to a wringing operation.

Figure 3 is a front View of the mop with the wringer attached thereto as in Fig. 2.

Figure 4 is a View illustrating the wringer attached to a mop with the latter partially wound thereon. y

25 Figure 5 is an edge View of a mop with the wringer appliedthereto and. fully wound thereon in a final step in the wringing operation.

A Figure 6 is a view illustrating a modified form of the wringer.

3b Figure '7 is another View of the same illustrating the wringing operation.

A purpose of my present invention is to provide a light structure which, however, may be effectively used for wringing operations, the

3'5 wringer shown herein in the drawings being composed of wire. In such construction a length of wire is formed near its lengthwise center with a coil E in the form of a spring that will tend to move the branches I and 8 extending from the coil one away from the other. At the end of the branches 1 and 8 which constitute a handle and lever the wire is bent at substantially right angles to said branches to form jaws or clamps 9 and I0 extending in parallel relation in position to receive mop material Il which, in the form of mop shown herein, is composed of cotton threads or cords extending from a mop frame I2 secured at the lower end of a frame clamp I3 attached to the lower end of a handle I4, as shown in Figs. 2,

50 3 and 5 of the drawings. The ends of the jaws 9 and I0 are formed into rings I5 and I6. A retainer I'I in the form of a ring encircles the jaw 9 and branch 'I at the points where said parts cross each other and as clearly shown in 55 Figs. 1 and 3 of the drawings, this being for the acting as levers, a ycomparatively little force appurpose of preventing lateral separation of the branch 'I and jaw 9.

In the operation of the wringer the jaws are separated by squeezing, as with the hand, the branches 1 and 8, closing said branches together, 5 in the structure shown herein the jaw I0 separating from the jaw 9, as shown in dotted lines in Fig. 1, and the retainer I1 moving to the dotted line position. This enables the mop material II to be placed between the jaws after which pressure on the branches 1 and 8 being released, the jaws will close upon the mop and clamp it with a rm hold. t Y

The branches I and 8 and coil 6 are now operated as a crank to wind or., roll the mop material around the jaws 9 and I0, and as shown in Figs. 4 and 5 of the drawings. When the mop material has been fully wound as shown in Figs. 4 and 5 of the drawings, force applied to they handle or crank vI8 comprising the branches 1"' and 8 and coil. 6 will tightly squeeze the mop material within the rollthus formed and the water will therefore be eiectively squeezed and removed from the mop.

To perform this wringing operation said handle I8 acts as a lever towhich, after the mop has been wound, asshown in Fig. 5, force is lapplied byv one hand while vthe handle I4 of the mop is heldbythe other hand. At this time the handle g. I4 andthe lever I8 areforced in opposite directions, the handle I4 being forced to theleft and the lever I8 being forced to the` right, as'shown in Fig. 5. These two members I4 and I8 both vplied thereto in oppositev directions by the hands 5 effects a most powerful action upon the mop in lthe wringing operation.

The rings I5 and I6 are formed at the free ends of the jaws or clamps 9 and t0 for a twofold purpose: At the beginning of the operation of winding the mop material around the jaws, and before the material has tightly encircled the jaws, there is a tendency for such material to force the jaws apart laterally of the plane of the device, thereby loosening the grip of the jaws upon the material, and the rings overlapping past each other, as shown in Fig. 4, prevent such separation and loosening of the grip of the jaws upon the material. The crank or handle com- 50 prising the branches 'I and 8 and coil 6 being turned in a clockwise direction, as shown in Figs.

2 and 5, the rings will be forced toward each other, and not being able to pass each other the grip of the jaws will be tightened.

Again as the mop material is wound upon the jaws there is a tendency for the threads at this edge of the mop to slide toward the ends of the jaws, and the rings form a stop to prevent this action and retain the threads in place so that all of the threads will be subject to the wringing operation.

In the mop structure shown herein the threads comp-risingthemop material are omitted*V at the center of one side of the frame "where the handle is secured to the frame, and this lack of material at the center of the frame results in a looseness of the threads thereby preventing them -from being tightly squeezed in the wringing operation. To avoid this result the yjaws are enlarged or bulged as at 20 as shown in' Fig. 6 to lll'the space created by this lack of material and thereby to effect a tight winding of the mop threads. These bulged portions form depressions 2l particularly at the back end of the jaws, these depressions receiving theI threads and. preventing them. from being crowded oi the jaws. at .this .endfof the structure. v f
