Specification of Letters Patent.
Patented Sept. 26, 1905.
Application filed November 22, 1904. Serial No. 233,810.
following is a specification.
This invention relates to brushes of that class in which the back is provided with slits located between the rows of bristles for the purpose of-permitting the water and air to pass freely through .the brush-back to the bristles for ventilating and drying the same,
as in tooth-brushes and the like, so that the brush may be readily cleaned and maintained in a clean condition; and. for this purpose'the invention consists in a brush embodying the back is provided with longitudinally-extend ing rows of narrow longitudinally-disposed slits a, which extend through the same between the rows of bristles, the adjacent slits being merged into eachother upon the face of the brush-back, but separated from each other at the rear of the same by transverse solid portions 19, as shownv in Fig. 3. The
sides of the longitudinal slits a are parallel, so as to allow sufiicient space for the insertion of the tufts of bristles into the face of the brush-back, and the openings or are arranged in rows or sets which extend transversely of the brush-back, as shown in Fig.
1. Upon the rear of the brush-back the slits a are surrounded by outwardly-flaring recesses ,.which form funnel or pocket like spaces for facilitating the passage of water when cleaning the brush to the slits and along the rows of bristles at the opposite side of the brush. The said pockets 6 also serve after the brush hasbe'en cleaned for permitting the air to pass throughthe slits, and thereby ventilate the bristles, so as to dry them more quickly than is possible in the ordinary very narrow, so that the stock of the brushback, through 'whichthe bristles are inserted in the usual manner, is not encroached upon to too great an extent and the strength of the brush-back is not impaired as a consequence.
'Heretofore brushes withlongitudinal slits or openings in the back have been found to break 'upon dropping the same, as the solid portions of the brush-back into which the bristles are inserted, cannot resist the shocks incurred. This is obviated by the improved brush-back, in which the face only. is longitudinally 'slitted, While the slits in the rear of the back do not merge into each other, but are separated by intermediate solid portions, by which the brush-body is strengthened at its rear part and is thereby less liable to accidental breakage while handling the same.
Having thus described my invention, 1 claim as new and desire to secure by Letters Patent ROBERT A. WHITE.
