CLEANING IMPLEMENT.

Application filed January 30, 1925.

This invention relates to that class of cleaning implements comprising brushes,

mops and similar articles, and an Object of the invention, among others, is the production of simple and efficient means for -securing handles to such devices.

One form of cleaning implement embodying this invention 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 View of a brush showing one form of bracket attachment for a handle. l

Figure 2 is a View in section on a plane denoted by the dotted line 2 2 of Figure 1.

Figure 3 is a view of a brush showing another form of bracket attachment for a handle.

Figure 4 is a view in section on a plane denoted by the dotted line H of Figure 3.

Figure 5 is a detail view of a portion of a brush structure illustrating the form of the ends of the core for engagement of the attaching bracket.

Figure 6 is an isometric view of the form of the bracket shown in Figures 1 and 2.

Figure 7 is a similar'view of the form of the bracket shown in Figures 3 and 4.

The invention illustrated and described herein may be well applied to many forms of cleaning implements such as mops, floor brushes, wall brushes and the like, and

tures embodying a twisted wire core, and for the purposes of disclosure of the invention there has been selected a brush comprising bristles 8 that are secured to a twisted wire core 9 in a manner common to structures of this class. This core is disposed in the form of an inclosing frame, the shape illustrated herein being that of oblong form with rounded ends, and the ends of the core are brought into proximity at one side of the frame and these ends 10 are cxtended Vor bent inwardly for engagement with an attaching bracket 11. In the preferred form of construction these ends are bent into the form of backturned hooks for the purpose ot' a secure fastening.

The bracket is made in the shape of a bow and comprises branches 12 and a bow 13. This is preferably formed from sheet especially, tho not necessarily, to such struc-v Serial N'o. 5,768.'

for the reception of an attaching device to pivotally connect the handle to the brush, one form of such an attaching device comprising a spring connector having branches 17 with outturned ends 18, as shown in dotted lines in Figure 6 of the drawings.

It will be noted that the backturned ends are so secured to the bracket that they extend transversely to the line of force applied to the tool by the handle in useso that said ends will not be disengaged from the grooves in the edges of the tool, and no means, other than the clamping means, are required to retain the ends in place.

In the form of the device illustrated in Figure 1 the free ends of the branches 12 are unsupported, but in the structure shown in Figure 3 these branches are extended for engagement with the side of the frame formed by the wire core and opposite the ends 10, the ends of said branches being formed with holes through which the core extends. v

In accordance with the provisions of the patent statutes we have described the principles of operation of our invention, together with the device which we now consider to represent the best embodiment thereof; but we desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above set out as contemplated by the appended claims.

We claim- 1. A cleaning implement including cleaning material secured to a core in the form of a closed looped frame and with the opposite ends of said core extending inwardly of said frame and bent backwardly to form hooks extending transversely to the lines of force applied by a handle to the tool in use, a handle attaching bracket having grooves formed to receive said ends and thereby support said bracket, and means for rigidly securing said bracket to said ends within said frame, said bracket having means for the pivotal attachment of a handle thereto.

2. A cleaning implement including cleaning material secured to a core in the form of a closed looped frame and with the opposite ends of said core extending inwardly of said frame, an attaching` bracket ofU-sliape comprising substantially parallel branches and a bowv uniting said branches, said bracket being rigidly secured to said frame,

i means lon said branches for pivotal attachment of a handle, and means on said bow for attachment of said inwardly extending ends to position said ends extended transversely to the lines of force applied to the handle of the tool in use.

3. A cleaning implement including cleaning material secured to a core in the form of a closed looped frame and with the opposite ends of said core bent `inwardly and backvwardly within said. frame, and a bracket comprising branching arms connected by a bow and with a groove in the outer edge of the bracket, and lugs on `the bowed portion of the bracket for securing said backturned arms within said groove.

4l. A cleaning implement including a core having cleaning material secured thereto, said core being formed into .a closed loop and the ends of said core being bent inwardly thereof, a bracket secured at one end tothe inwardly bent ends of said core and at its opposite end to the opposite side of said `frame, and means for attaching a handle to z said bracket.

5. A cleaning implement including a core having cleaning material secured thereto, said core being formed into a closed loop frame, the ends of said core being bent inwardly wit-hin said frame, a bracket of yoke shape with its bent end rigidly secured to said ends of the core, and with the ends of its branches secured to said frame, and means for attaching a handle to said bracket. Y

6. A cleaning implement including cleaning material secured to a core in the form of a closed looped frame, the ends of said frame being connected by a bracket compris` v ing branching arms connected by a bow and with 4a groove inthe outer edge of the bracket, the opposite ends of said core being bent inwardly and extended along said bow, and lugs on the bowed portion of the bracket for securing the ends of said arms within said groove.
