SPECIFICATION forming part of Letters Patent No. 758,082, dated April 26, 1904.

Application ua'craimy 14,1904. serial No. 189,049. (remodel.)

T0 (LM whom t may concern:

Be it known that I, GEORGE L. LAMB, aciti.- Zen of the United States of America, and a resident of Nappanee, in the State of Indiana, have invented a new and useful Improvement in Sweeping-Brushes, of which the following is a specification.

This invention relates to sweeping-brushes made up with tufts of tampico or`like vegetable fiber. In brushes made of this fiber after they have been inuse a while the tufts become so matted together that the brush becomes useless, especially if made of long ber.

The leading object of the present invention is to prevent such matting and to make a liber brush as elastic as a bristle brush.

Other objects are to facilitate the construction of the improved brush and to provide for readily adjusting the spreaders to compensate for wear, so as to prolong the life of the brush.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 is a full length perspective View of the improved brush. Fig. 2 is a face view of the head with some of the tufts removed to expose to view the parts inclosed by the liber. Fig. 3 represents a cross-section on the line A B, Fig. 2. Fig. 4 is an end view of the brush-head with some of its tufts removed as shown in Fig. 2, and Fig. 5 is a perspective view of one of the spreader-attaching devices hereinafter described.

Like reference numbers and letters refer to like parts in all Ythe figures.

The brush-head 1 is preferably and conveniently of an ordinary oblong form of wooden head, having tuftsockets a in longitudinal rows, as shown at the ends in Fig. 2, and a central bolt-hole b, shown in the plane of section in VFig. 3. Either of the longitudinal edges c and CZ of the head 'may be its front edge, both being preferably and conveniently parallel with said tauft-sockets a.. The fiber 2 may be securely fastened in rows of tufts within said tuft-sockets a in any known or iinproved manner. The spreaders in pairs, 3 4 and 5 6, of sti wire, having rebent ends, are loosely inserted between the rows of tufts and are pivotally attached to the under side of the head1 by a pair of pivoting and adjusting

devices

7 and 8, one of which is segregated by Fig. 5. Each of these devices is xedlyheld in place on the head by a wood-screw e. Each comprises an L-shaped angle-piecef, provided with the screw-hole and with a longitudinal slot 9, Figs. 4L and 5, in its perpendicular leg, a cross-bar g, having a pivotal hole 10, Fig.

i 5, for each spreader and a central hole, and a bolt or screw fr, occupying said central hole and extending through said slot 9 in the perpendicular leg of the device. By loosening, moving, and retightening said screw h, and

therewith said cross-bar g, each end of VtheV spreader-s 3, 4, 5, and d as a whole may be moved toward the head 1 to compensate for the wear of the liber 2 and 'restored to effect` ive condition. The spreading of they fiber 2, which is the main object of the invention, is primarily eected by springs'll, 12, 13, and 14, reacting against the spreaders', 4, 5, and 6, In the form shown each spring Yreacts against a pair of spreaders to which it is selfattached, being U shaped, with suitablyhooked ends, as shown in Fig. 3.

rlhe handle 15, Fig. 1, is preferably attached at a suitable angleto one of the longitudinal edges c or UZ of the head 1 by means of a socket-piece 16, having a steadying-lip a' to engage with such edge of the head, a central bolt 17 extending upwardly through said bolt-hole l) of the head and through a superadjacent portion of said socket-piece, and a thumb-nut 18 on said bolt. By loosening and reversing said socket-piece 16, asrrepresented by dotted outlines in Fig. 3, the lopposite edge of the head may be changed to its front, and any uneven Wear of the fiber 2 may thus be corrected. A

rIhe number of spreaders will obviously depend on the number of the rows of the {ibertufts, whic'h is "variable in brushes of different makes. The form, number, and arrangement of the springs may be changed without materially departing from the construction above described. The ber maybe otherwise attached in rows, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specification- 1. A ber sweeping-brush provided with fiber-spreading springs, substantially as hereinbefore specified.

2. A ber sweeping-brush having rows of' the fiber separated by spring-pressed spreaders to spread the fiber, substantially as hereinbefore specified.

3. A ber sweeping-brush having rows of the ber separated by spring-pressed spreaders in pairs and springs reacting against said spreaders to spread the fiber, substantially as hereinbefore specified. l

4. A fiber sweeping-brush having rows of the fiber separated by spring-pressed spreaders in pairs and self-attached U-shaped springs reacting against said spreaders to spread the ber, substantially ashereinbefore specied.

5. -A fiber sweeping-brush having a head provided with rows of the fiber, loose spreaders between the rows., means for pivotally attaching said spreaders tosaid head, and springs reacting against said vspreaders to spread the ber, substantially as hereinbefore specified.

6. A fiber sweeping-brush having a head provided with rows of the ber, loosezspreaders between the rows, means for pivotally attaching said spreaders to said head, means for adjusting the spreaders toward the head to compensate for the wear of the ber, and springs reacting against said spreaders to spread the ber, substantially as hereinbefore specified.

7-. The combination, in a sweeping-brush, of a head provided with ber in rows, spreaders between such rows of the ber, springs reacting against saidv spreaders to spread the fiber, and a pair of pivoting and adjusting devices each comprising an L-shaped piece fixedly attached to' the head and having a longitudinalslot inl its perpendicular portion, a cross-bar provided with pivot-holes'for the respective spreaders, and aycentral screw eX- tending'through said slot and said cross-bar, substantially as hereinbefore specified. v
