Specification of Letters Patent.

' Application filed November 4,1908. Serial No. 461,094. a

To all nhomtt may concern:

Be it known that I, JAKOB KNoLLnR, a sub ect of the German Emperor, and residentof 73 Ritterstrasse, Berlin, Germany,-

have invented certain new and useful Improvements in and Relating to Brushes, of which the following is a specification.

-My present invention relates to such brushes which are used wet" e. g. toothbrushes or hand-brushes or nail-brushes and it serves for tliepurpose to better and quicker clean and dry the single sets of bristles by moving the same apart for any suitable't-irne so. preventing a collecting of injurious germs between the single bristles.

. For/this purpose the part carrying the brush consists either of elastic waterproof material so that-it may be accommodately bent and fastened. in this bentform or the sets of orin any other suitable manner.

'raril bristles can be placed on single rods which can be. moved apart by any suitable means. The elastic waterproof brushes can be fixed after their use in a bent position between suitable arresting. means fixed to the brush holder.

The rods carryin the bristles may consist either of longituc inalor of cross-rods. Some of these rods can be removed tempofrom the others in such a manner that a ro with bristles alternates with. a groove or cuttin by which motion the desired sepafrom each other can be effected by swiuging, turning, pushing or bending the same In the accompanying drawing in which I have illustrated my invention like letters of reference refer to like parts throughout the different views.

Insaid drawing, Figure 1 shows a perspectivexview of a tooth-brush in which the part carrying the brush is removed, Fig. 2 shows a perspective view of the part carrying the brush, Fig. 3 shows a perspective view of a toothbrush in which the part carrying the brush is bent and arrested in this osition between pins fixed to the holder. Figs. L-ll show other construction of fastening the part carrying the brush to the brush holder. Fig. 12 shows a side .view of a .by a United States Letters Patent,-1s:--

hand-brush, Fig. 13 showsa side view of a hand brush the brush being removed from its working position, bent, and inserted into grooves arranged on the back of the holder.

As shown in Figs. 1-3 the brush-holder 1 guide 6.

provides a guide 2 havin fastening means e. g. pins or screws or pro ect-ions or the like. These fastening means serve at one hand for the purpose to secure a safe fastening of the body carryin the brush 4; hereafter called the brush. an at the other'hand as stops for the elastic endsof the bent brush, preferably consisting of elastic and waterproof mate-. rial. In Fig. 3 it is shown how the bent brush 4 is inserted e. between the inner edge of the guide 2 and a pin 3.

Figs. 4, 5, and 6 show a form of construction of a tooth brush in which'the brushholder is. provided with a dovetail like After the use of the brush the same is drawn apart of its hold-er'5 and the elastic ends of the bent brush 4 inserted into cuttings 7 and 8 of the guide (Fig. 6). The securing of the brush against dropplng out is attained by anysuitable means.

Figs. 7 8, and 9 show a form of construction of a tooth brush in which-the brush holder 9 is provided with perforations l0 arranged always between two sets of bristles.

' The brush 12 (Fig. 8) is inserted into the holder 9 bypassing its bristles 13 through said perforations 10. In this construction it is not necessary to make the brush of elastic material as the same is not bent. The fastening of the brush 12 to the holder 9 is attained in any suitable manner.

Figs. 10 and 11 show a form of construction of a tooth-brush in which the sup orting end of the brush holder forms a t reepronged fork 15. The prongs 15- are provided with sets of bristles and along their inner side with grooves 16 into which fits the. part- 17 also carrying sets of bristles and providing guiding borders 18. The fastening of the parts 17 to the part 15 can be attained in any suitable manner.

Figs. 12 and 13 showa handor nail-brush. The fixing of the brush 21 to the plate 19 of the holder can be attained according to any of the above described construct-ions. The handle 20 provides cuttings 22 into which the bent brush is inserted after its use.

The single. arts of my'improved brush can of course' chan ed in form and construct-ion wlthin the lim t of my lnventlon. That I claim as new and deslre to secure Patented. Dec;
