JACOB MEINHARDT, OF CHICAGO, ILLINOIS.

MOP FRAME.

Application filed January 24, 1923.

To all whom it may concern:

Be it known that I, J AooB A. MEINHARDT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Mop Frame, of which the following-is a,

specification.

This invention relates to mop frames, and more particularly to such frames constructed of a loop of supporting material to which the mop proper may be removably attached. It will be fully understood from the follow ing description, illustrated by the accompanying drawings, in which a mop constructed in accordance with the present invention is shown in Figure 1 in vertical section and in Fig. 2 in plan.

In mop frames constructed in accordance with the present invention, the portion of the frame forming the support for the mop is arranged as a loop, at some suitable point in which an opening is provided to permit a mop to be threaded thereover. A portion of the material forming the mop supporting loop is turned inwardly of the mop supporting loop and formed into a partial or complete loop lying within the mop supporting loop and preferably in substantially the same plane. To this internal loop portion of the mop frame, a center plate is secured,

this center plate likewise lying in substantially the plane of the frame. A suitable support for the handle of the mop is secured to the frame in such a way as to permit pivotal movement of the mop handle. The center plate provided within the loop is spaced from the latter to permit the free movement of the mop cloth thereover. It acts in part as a bearing plate for distributing over the fibers of the mop itself any downward thrust applied to the mop handle.

Referring more particularly to the drawings, the numeral 5 indicates a metal rod, preferably of circular section, bent to form a loop for the support of the mop cloth indicated in dotted lines by the numeral 6. In the form illustrated the mop supporting loop is substantially triangular in form. At a suitable point in the loop, the mop supporting rod is bent inwardly, and the inwardly bent port-ion is curved to form a partial loop 7 in substantially the same plane as the mop supporting loop portion 6. Plates 8 are formed with depressions corresponding in shape to the shape of the internal loop 7, and one of these plates is Serial No. 614,594.

placed on each side of the internal loop 7 with the latter lying in the tube-forming depressions 9, the plates being then riveted together. As illustrated in the drawings, the depressions 9 in the plates 8 may be formed with portions 9 extending beyond the end of the internal loop 7 these portions being disposed to form a symmetrical figure and aiding materially in strengthening the plates. Depressions 10 are likewise formed 7 in the plates 8 extending transversely across the loops formed by the depressions 9. Before assembly of the device, a pin 11, which serves as a pivot for the handle socket, is arranged in the depressions 10, which thus form alining sleeves about the end-portions of the pin.

The handle socket 12 is provided with projecting ears 13 having openings let through which the pivot pin 11 passes. A helical spring 15 is inserted over the pivot pin 11 between the ears 18. The central portions of the plates 8 are cut away within the loops formed by the depressions 9, the portions adjacent to the transverse depressions 10 being substantially straight and substantially parallel as indicated at 16, to provide bearing surfaces for the outsides of the ears 13. On each side of the straight portions 16, the cutaway portion is enlarged to permit free movement of the handle socket 12.

The shape of the plates 8, which together form a bearing plate, is substantially similar to the shape of the figure formed by the loop 5. The outer periphery of the bearing plate is spaced from the mop supporting loop so as to permit free movement of the mop cloth on the latter. The curving of the inwardly projecting portion 7 of the mop supporting rod imparts rigidity to the bearing plate and prevents its movement out of the plane of the mop supporting loop 6'. In case of downward thrust on the handle 17, which is inserted within the socket 12, the thrust is received by the bear ing plate 8 and distributed by it over such of the fibers of the mop 6 as may lie within the loop 5.

Although the present invention has been described in connection with the specific details of a preferred embodiment thereof, it is notintended that these details shall be regarded as limitations upon the scope of the invention, except in so far as they may be included in the accompanying claims.

I claim 1. A supporting frame comprising an outer mop supporting loop, a second loop formed integrally therewith and located antirely within the mop supporting loop, a bearing plate secured to the internal loop of the frame and having its periphery terminating adjacent said outer loop and spaced therefrom to permit free movement of the mop on said outer loop, the inner and outer loops and the bearing plate being in substantially the same plane, and a handle support secured to said bearing plate.

2. A supporting frame comprising an outer mop supporting loop, a second loop formed integrally therewith and located entirely within the mop supporting loop, a bearing plate secured to the internal loop of the frame and having its periphery terminating adjacent said outer loop and spaced therefrom to permit free movement of the mop on said outer loop, the inner and outer loops and the bearing plate beingin substantially the same plane, alining sleeves formed from depressions in the bearing plate, alpivot mounted in said sleeves, and a handle socket carried by said pivot.

3. A mop frame comprising a looped mop V supporting member, one end of said member terminating at a point in the periphery thereof, an internal loop portion formed by the other end of said looped member, the latter being curved inwardly from a point on the periphery spaced from the first mentioned end thereof, a bearing plate within the mop supporting loop and secured to the internal loop portion thereof and a handle socket pivotally secured to said'plate'.

4:. A mop frame comprising. an open looped mop supporting member formed with an internal loop portion, plates on eachside of said internal loop, said plates being provided withdepressions into which i said internal loop portion fits, transverse depressions formed in said'plate, a pivot pin fitting within said. transverse depressions, and a handle socket mounted on said pivot pin.
