"I III!!! YIIIIIIIIIIIIIII l m u I u m I ATTORNEY Patented Oct. 15, 1929 UNITED STATES WILLIAM M. NEISSL, OF CHARLESTON, ARKANSAS TOOTI-IBRUYSH Application filed September 25, 1928. Serial No. 308,291.
My invention relates to tooth brushes.
An object of the invention is to provide a tooth brush wherein the brush head may be converted from a convex surface into a concave. surface, or vice versa.
The invention further provides a tooth brush embodying a plurality of brush head sections and latch means for holding them in such relation as to produce either the concave or convex surface, as desired.
With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, constructions and arrangements of parts to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein:
Figure 1 is a side elevation of the invention, illustrating the brush head in convex formation,
Figure 2 is a similar View, but illustrating the brush head in concave formation,
Figure 3 is a fragmentary longitudinal sectional view of the device,
Figure 4 is a transverse sectional view of the same, and
Figure 5 is a fragmentary perspective- View of the invention.
Referring to the invention in detail, a handie 5, formed with a longitudinally extending channel shaped member 6 at one end, is provided. As illustrated in Figure 5, the parallel walls of the channel shaped member are formed with oppositely extending lateral flanges 7 A pair of brush head sections or blocks 10 and 11, each carrying bristles 12 upon its inner face, are provided for association with the channel shaped member. It will be observed that the bristles of each brush head section or block are graduated in length, so that when the sections are arranged in the end to end relation disclosed in Figure 1, a convex brushing surface will be produced. However, when the reverse ends of the sections are disposed in end to end relation, the bristles will present a concave brushing surface, as disclosed in Figure 2.
For the purpose of mounting, the brush head sections on the channel shaped member,
so that the brush may be converted from a concave brush to a convex one, or vice versa, the underfaces of the sections or blocks 10 and 11 are provided with parallel L-shaped flanges or guides 15, which slidably engage the flanges 7.
In order to latch the sections or blocks against longitudinal movement on the flanges 7 a resilient latch bar 16 is provided. As illustrated in Figures 3 and 4, the or length of the latch bar is offset from the intermediate wall of the channel shaped member, and has its inner end secured to this intermediate wall, as at 17. A pair of upstanding lugs 18 are formed on the upper face of the latch bar, and are normally received in openings 19 in the underfaces of the sections or blocks. At its forward end the latch bar projects beyond the inner end of the block 10 to provide a longitudinally curved finger engaging member 20, whereby the latch bar may be depressed to disengage the lugs 18 from the recesses 19.
Assuming the brush head sections to be arranged as illustrated in Figure 1 and it is desired to provide a concave brush. The latch baris first depressed, and the brush head section 10 slid forwardly to displace the brush head section 11 from the channel shaped member. The brush head section 11 is now arranged with its forward end facing the inner end of the section 10, and slid forwardly on the flanges 7 until the two sections abut. Upon releasing the latch bar, the lugs 18 entering the recesses 19 will latch the brush head sections against movement.
What is claimed is:
1. In a brush, a channel shaped body having longitudinally extending lateral flanges, a plurality of brush head sections received on the flanges, and a resilient latch element extending longitudinally of the intermediate wall of the body and normally engaging the under face of the brush head sections to hold them against accidental displacement.
2. In a tooth brush, a body, oppositely extending lateral flanges formed thereon, a plurality of brush head sections each having parallel guides slidably embracing the flanges and a recess in its under face, a resilient latch element carried by the body and underlying the sections and lugs carried by the latch element and engaging the recesses to hold the sections against accidental displacement.
3. In a tooth brush, a channel shaped mem- 5 her formed with oppositely extending lateral flanges, a plurality of brush sections, each including a block having parallel guides on one face and slidably received on the flanges, and a depressible longitudinally extending latch 10 bar carried by the channel shaped member and normally engaging'the blocks to hold the same against accidental longitudinal shift WILLIAM M. NEISSL.
