SCRUBBlNG- BRUSH.

$PEG1FICATION forming part of Letters Patent No. 678,051, dated July 9, 1901.

Application filed March 19, 1901. $eria1 No. 51,918. (No model.)

.To all whom it may concern.-

Be it known that I, JOSEPH B. SOHWEIGER, a citizen of the United States, residing at Beaverdam, in the county of Dodge and State of Wisconsin, have invented certainnew and useful Improvements in scrubbing Brushes;

and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The purpose of the present invention is the provision of a scrubbing or floor brush which will remain squarely upon the floor or surface without reference to the angular position of the handle, thereby enabling the operator to assume various positions while moving the brush back and forth, which is of material advantage with reference .to uniformity of wear of the bristles or brush material and to the ease and comfort of the user.

The invention also contemplates provision of means for coupling two or more brushes in series, the connecting means serving as a part of the attaching contrivance between the brush head and handle.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptiblo of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a plan view of a brush embodying the invention. Fig. 2 is a side view thereof, the dotted lines indicating an adjusted position of the handle. Fig. 3 is a front view, one of the coupling-bars being in section.

Correspondingand like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The brush may be a single element or composed of a number of sections, the latter construction being indicated in the drawings, so as to show. the advantage of the couplingbars. The handle 1 has pivotal connection with the brush and is provided at its attaching end with a fork or bail 2, having outwardly-extending journals 3 to obtain bearings in openings formed centrally in the coupling-bars-4. with a tang which is fitted to the handle 1 in any desired way.

The coupling-bars 4, two in number, are arranged in parallel relation and are of L form in transverse section, the horizontal wings being apertured to receive screws or fastenings 5, by means of which the bars are attached to the back of the brush 6 and their vertical flanges tapering or decreasing in height from a central point toward their ex- The fork or bail 2 is provided dependent upon the size of the brush and serve to brace the latter and to admit of a number of sections or small brushes being joined in series, so as to form a-brush of required size.

The fork 2.and its tang are of rigid st'ruc ture, and the journals 3 are fitted into the openings of the couplingbars 4 prior to the attachment of the last coupling-bar to the brush. is free to move to any angular position with reference to the plane of the brush. Hence pressure can be'exerted to hold the brush upon the. floor and every part thereof will be caused to wear alike and to operate with a uniform pressure. Hence the operator need only move the brush back and forth over the floor and surface and apply any degree of force to the handle with the assurance that the brush will rest squarely upon the floor or surface and receive uniform wear, which is essential. When the brushes are coupled in series, should the outermost brushes Wear unevenly they can be shifted by disconnecting them from the bars 4 and rearranging them to the best possible advantage.

Having thus described the invention, What is claimed as new is-- A brush comprising a plurality of sections or small brushes arranged in series, independent coupling=bars connecting the brushes or sections and comprising horizontal and vertical flanges decreasing in height and width,

It will be observed that the handle respectively, toward their extremities, the vertical flanges having transversely-aiming openings intermediate of their ends, and a handle having a fork at its attaching end provided with outwardly-extending journals obtaining hearings in the said coupling-bars, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
