JOHN O. NEVIUS, OF TRENTON, NEW JERSET,

ASSIGN OR OF ON E-IIALF TO TOOTH-BRUSH GUARD I Patented April 23, 1907. 1906. serial No. 332,790.

To all whom it may concern/.-

Be it known that I, JOHN C. Nnvms, .of Trenton, in the county of Mercer and State of N ew. Jersey,'have invented certain new I and useful Improvements in Tooth-Brush Guards; and I hereby declare that the fol- I lowing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

g This invention is a novel device especially designed for use in connectionwith tooth brushes, nail brushes, and like toilet articles, to prevent the water, dripping from the brushes when in use, soiling the hands, cuffs, sleeves, etc. of the user; and also to serve as a support for the bristle-portion of the brush when the brush is laid down, so that the bristle-portionwill be aired, and the brush can be more readily picked up; and also to serve as ameans for supporting the brush when inserted in a rest w thout crushing the bristles,and to also serve as a means for identifying individual brushes, for which latter purpose the devices are provided with initials or distinctive symbols so that each brush can be readily distinguished from others by its owner.

Theinvention consists in a small tubular rubber shield, preferably bell-shaped, and having its bore provided with an annular recess or pocket whereby the outer wall portions are thinned so that while the shieldcan be readily slipped on the handle of a brush or other device of larger diameter than the bore, it will not be materially distorted externally, as the thin walls at the ends of the bore can yield readily without causing any material deflection of the main body of the shield,- and at the same time the shield will have two bearing points or constricting portions whereby it will be securely held in place upon the handle.

The shields may be made of distinctive colors, and further provided with initials, or

individual owners can readily distinguish their own articles to which the shields are applied.

' The invention will be clearly understood from the accompanying drawings, in which- Fi ure 1 is a perspective view of a shield attac led to a tooth brush, and indicating its usefulness. Fig. 2 is an enlarged longitudi- 'the end walls d of the nal section through the shield as attached to a brush-handle. Fig. 3 is a transverse sec- 5 tion on line 3E3, Fig. 2, looking in the direction of the arrows.

The shield A is preferably conical or hellshaped, being larger at one end than at the other, and flared outwardly from the small to the larger end; the lar er end being concaved, as at a. The shield has as axial open ing or bore 6, which is slightly less in diameter than the diameter of the handles it is intended to engage, so that it will clamp the latter when forced thereon. Intermediate the ends of the bore the shield is formed with an annular recess or pocket 0 which leaves bore quite thin, compared with the length of the shield, and thus 7 gives the shield two bearings at d, d, upon the brush handle H.

The shields are preferably made of Pararubber, and of any desired color. And for purposes of identification they are preferably ormed with distinctive symbols, such as initial letters on their outer faces, as indicated at e, in the drawings. When applied to a brush, the shield is slipped endwise on the brush handle, with the larger or concaved end a toward the bristle end of brush; the thin walls d will yield so that the shield can slip over irregularities in the surface of the handle, or past enlargements in diameter of the handle, to the desired positio n,where it will be firmly held by reason of the natural constriction of the arts 11.

In passing over arger or swell portions of the handle the parts can yield readily, be-

cause they are substantially independent, by

reason of the intermediate pocket or recess 0 which allows the parts (1 a certain amount of inde endent expansion and flexion without pro ucin any appreciable or undesirable dis tortion of the body of the shield, which would be distorted if the bore 1) was of uniform diameter throughout. This pocket or recess 0 therefore is a very useful and important fea* ture of the shield.

When the shield is in place, on a tooth- 1 brush for example, as indicated in Fi 1, it will prevent water running down the andle H onto the hands of the user, and soiling the linen of the user,the water being caught by the shield and discharged as indicated in I Flg. 1.

Obviously the shields can be applied to paint-brushes, pen-holders and various g other implements and tools, and I do not therefore Wish to be restricted to its use= bore having an internal annular pocket or recess, substantially as described.

merely for brushes, as shields thus constructed are applicable to and useful on many other articles.

Having described my invention What I 2 claim as new and desire to secure by Letters Patent is:

1. A shield for brushes, provided with a I 2. A rubber shield .for brushes, having one end concave, and provided with a central bore having an'internal annular pocket E .or recess, substantially as described.

the purpose described.

5. The herein described shield for brushes, comprising a conical or bell-shaped soft rubber body, having its larger end concaved,

small diameter atit-s ends, and with an internal annular pocket or recess, leaving the end Walls of the bore flexible whereby material distort-ion of the body of the guard is prevented and for the purpose described.

In testimony that I claim the foregoing as my own, I afiix my signature in presence of two Witnesses.
