BRUSH.
Specification of Letters Patent.
Patented Nov. 24, 1908.
Application filed. May 18, 1908. Serial No. 433,336.
To all whom it may concern:
Be it known that I, JOHN NELSON, a citizen of the United States, residing at Peru, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Brushes, of which the following is a specification.
My invention relates particularly to fleshbrushes, and my primary object is to pro vide an inexpensive brush of the character indicated capable of giving improved results in operation.
The invention is illustrated in its preferred embodiment in the accompanying drawing, in which Figure 1 represents a back view of my improved brush; Fig. 2, a front face view of the same; Fig. 3, a longitudinal sectional view taken as indicated at line 3 of Fig. 1; and Fig. 4, a transverse sectional view taken as indicated at line 4 of Fig. 2.
The brush is of hollow formation, comprising a relatively thick lower wall 1, a thinner upper wall 2, and a handle or strap 3, which may be formed integrally with each other. The lower surface of the wall 1 is equipped with bosses 4: into which extend bores or openings 5, said bores 5 being of sufficient depth to reduce the thickness of the wall 1 thereat, thereby providing the flexible diaphragms 6 at the inner ends of the bores. In the molding operation, the dlaphragms 6 are bowed upwardly, as shown. By preference, the lower wall of the brush is provided with a circumferential flange 7, which, however, does not extend flush with the extremities of the bosses, or cups, 4.
After the brush has been molded, air is introduced in the chamber 8, under slight pressure, the pressure being sufficient, however, to bulge the walls of the brush, whereby convexity is imparted in all directions. A needle may be employed to introduce the air, after which the perforation may be closed. The diaphragms 6, while flexible, are sufliciently strong to retain their upwardly bowed form under the small airpressure which normally is present in the chamber 8. One of the important features of my improved brush is the forming of each diaphragm 6 of comparatively thin material and bowing it up to project normally in a convex form from the inner face of the wall 1.
In the use of the brush, the walls of the brush are flexed, or forced, toward each other, thereby increasing the pressure within the chamber 8 and bowing the diaphragms 6 downwardly. As the pressure undulates, the diaphragms move, thereby creating suction during the operation of the brush.
The external convexity of the walls of the brush constitute a feature of advantage, inasmuc as the brush will conform more readily to thebody during the operation of the brush.
The foregoing detailed description has been given for elearness of understanding only, and no undue limitation is to be understood therefrom.
I/Vhat I regard as new, and desire to secure by Letters Patent, is
1. A brush comprising oppositely bowed flexible walls, cups formed in one of said walls and having flexible diaphragms at their inner ends, and a handle, for the purpose set forth.
2. A rubber brush comprising a relatively thick lower wall equipped with bosses with bores extending through said wall, leaving diaphragms at the inner ends of said bores, and a relatively thin upper wall forming an air-tight chamber with said lower wall, said walls being bowed both longitudinally and transversely, for the purpose set forth.
3. A brush comprising flexible rubber walls forming an air-space between them, and cups in one of said walls having diaphragms on their inner ends normally protruding beyond said cup-ends into said alrspace, for the purpose set forth.
4. A brush comprising flexible rubber walls forming an air-space between them, and cups in one of said walls projecting be yond the outer surface thereof and having concavo-convex diaphragms on their inner ends normally protruding their convex surfaces beyond said cup-ends into said airspace, for the purpose set forth.
JOHN NELSON.
In the presence of L. HEISLAR, R. A. RAYMOND.
