' BRUSH.

Specification of Letters Patent.

Patented Feb. 11, 1908.

Application filed July 8. 1907. Serial No. 382.794:-

To all whom it may concern:

Be it known that I, ROBERT C. BRYANT, a citizen of the United States, residing at Faroe, in the county of Smith and State of Mississippi, have invented certain new and useful Improvements in Brushes, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in brush heads for scrubbing brushes, stable brushes and the like.

The object of the invention is to provide a device of this character which is of simple, strong, durable and comparatively inexpensive construction and upon which the scrubbing material may be readily replaced when worn.

With the above and other objects in view the invention consists in the novel construction and the combination of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which Figure 1 is a plan view of my improved brush Figs. 2 and 3 are sectional views taken on the planes indicated by the lines 2, 2 and 3, 3 in Fig. 1, and Fig. 4 is a detailed perspeotive of one of the pivoted bars of the brush head.

In the drawings 1 denotes my improved brush head which comprises front and rear side bars 2, 3 and a pluralityof intermediate bars 4. These bars 2, 3, 4 are arranged in spaced parallel relation and between them are a plurality of pivoted bars 5 which are adapted to retain or secure the brush material 6 between the relative stationary bars 2, 3, 4 as more clearly shown in Fig. 2. The brush head also comprises two end bolts or equivalent clamping devices 7, 8 which serve to unite said bars. The bolt 7 passes through transverse alined apertures in the bars 2, 3,

4, 5 .and also through spacing washers 9 arranged on the opposite sides of each of the pivoted bars 5. Said bolt 7 not only serves as a clamping device for one end of the brush head but also as the pivot for the swinging bars 5 as will be readily seen upon reference to Fig. 1; The bolt 8 passes through alined transverse apertures in the bars 2, 3, 4 and also through spacing washersv or blocks 10 arranged between said bars and having concave sides so that they are smallest at their centers. The pivoted or swinging bars 5 are preferably formed by bending strips of sheet metal into substantially U form and arranging them so that their closed portions 11 are uppermost as seen in Fig. 2. The longitudinal edges of the depending side portions of the bars 5 are flared outward and are notched or serrated to provide teeth 12 which bite the brush material 6 and prevent the same from slipping when it is clamped in position. Formed in the upper edge of each of the bars 5 adjacent to its free end is a notch or recess 13 which is adapted to receive the reduced central portion of one of the spacing blocks or spools 10 and which is of such depth that a locking pin 14 may be inserted endwise intosaid bar 5 and above said block or spool as clearly shown in Fi s. 1 and 3. These locking pins, which may To of any suitable construction, will effectively connect the free ends of the bars 5 to the spacing blocks 10 and at the same time permit of the ready disenga ement of said bars so that the brush materia 6 may be removed hen worn.

If desired a handle of any suitable form and construction may be provided forthe brush head but the handle illustrated comprises a bar 15 secured upon a resilient tang -16 formed on one end of an angle plate 17 secured upon a centrally disposed transverse bar 18. This bar 18 is arranged in the upper portions of the outermost bars 2, 3 which latter are of greaterwidth at their centers than the intermediate bars 4, and it is passed through an opening'formed in the bar 3 and is retained in such opening by nails or other fastenings 19. The inner or rear end of the bar is formed with an enlargement or head which bears against the outer face of the bar pin and the forward end of said bar 18 is adapted to slide in a transverse opening or seat formed in the upper edge of the bar 2. It is retained in the latter by a plate 20 secured to the upper edge of said bar 2 as clearly shown in Figs 1 and 8.

The brush material 6 may be corn shucks, fiber, bristles or any other suitable material which will serve the purpose for which the brush is designed and which may be folded over the upper rounded edge 11 of the bars 5 and clamped between the teeth 11 of the latter and the opposite sides of the stationary bars 2, 3, 4, as seen in Fig. 2.

In making up my improved brush the nuts upon the threaded rear end of the bolt 7, 8 are preferably loosened, and the pins 14 are removed so that the pivoted bars may be swung outwardly to receive the brush ma terial 6. When the latter has been arranged .upon the bars 5 they are swung inwardly between the bars 2, 3, 4 so that their notched ends 13 engage the spacing blocks or spools 10. The locking pins 14 are then inserted in the ends of the bars 5 and above said blocks 10 as shown in Fig. 1, and the nuts of the bolt 7, 8 are then tightened so that the brush material 6 will be efiiectively clamped in the brush head.

Having thus described my invention what I claim is 1. A brush head comprising relatively stationary bars arranged in spaced parallel relation, brush material retaining bars pivoted to swing between said stationary bars and means for retaining said pivoted bars between said stationary bars, substantially as described.

2. A brush head comprising relatively stationary bars arranged in spaced parallel rela tion, brush material retaining bars pivoted to swing between said stationary bars, said pivoted bars being of substantial U shape cross sections and having their depending longitudinal edges flared outwardly and notched to provide teeth, and means for retaining said pivoted bars between the stationary ones, substantially as described.

3. A brush head'comprising relatively stationary bars arranged in spaced parallel relation, elements for spacing said bars apart, channeled bars pivoted for swinging movement between said stationary bars and adapted to retain brush material between the latter, said pivoted bars being notched to receive said spacing elements, and locking pins inserted in the ends of said pivoted bars and engaged with said elements, substantially as described.

4. A brush head comprising bars arranged svspoe in spaced parallel relation, bolts passed through said bars adjacent to their ends, brush material retaining bars pivoted at one end upon one of said bolts and adapted to swing between said spaced bars and means for detachably securing the free end of said pivoted bars to the other of said bolts, substantially as described.

5. A brush head comprising bars arranged in spaced parallel relation, bolts passed through said bars adjacent to their ends, means upon said bolts for spacing saidibars apart, brush material retaining bars pivoted at one end upon one of said bolts and adapted to swing between said spaced bars, said pivoted bars being notched to receive the spacing means upon the other bolt and looking pins inserted in said pivoted bars and engagement with said spacing means, substantially as and for the purpose set forth,

6. A brush head comprising bars arranged in spaced parallel relation, means arranged at the opposite ends of said bars for uniting and spacing them apart, pivoted bars arranged to swing between said parallel bars, brush material folded over said pivoted bars and retained between said parallel bars, a transverse bar secured to one of the outermost parallel bars and slidably engagedwith the other of the outermost parallel bars and a handle carried by said transverse bar, substantially as described.

In testimony whereof I hereunto affiX my signature in the presence of two witnesses.
