UNITED STATES WILLIAM L. HUMMEL,
or CHICAGO, ntmors. I
Application filed July 24,
To all whom it may concern:
Be it known that 1, WILLIAM L. HUMMEL, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Toothbrush Attachments, of which the following is a full, clear, and exact description.
My invention relates to improvement in tooth brush attachments, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide an attachment for tooth brushes by means of which the brush may be utilized for thoroughly and quickly cleaning plates of false teeth, particularly the upper plate.
A further object of my invention is to provide an attachment for tooth brushes having an auxiliary brush member which can be' quickly removed or attached to the tooth brush proper so as to permit of the latter being used in the ordinary manner or as a device for cleaning plates of false teeth.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming a part of this application, in which Figure 1 is a side view of a tooth brush proper with my improved attachment Figure 2 is a plan view of the device Figure 8 is a section along the line 3-3 of Figure 1, and
Figure 4 is a plan view of a modified form of the device.
In carrying out my invention I provide a tooth brush such as that shown in Figure 1, having a handle 1 and bristles 2., The bristles of the brush are preferably arranged so that their ends form a curve as shown in the drawing.

flanges 6 and which are designed to engage with the sides. ofthe head. 7
' The flangeso are arranged to hold. a brush. The latter is preferably madeof bristles 10 held by twisted wirell. flhis brush ispreferably curved as shown in Figure 2. The twisted wire has spring ends 12 which are arranged to enter between the opposed flanges 6 so as to frictionally hold the brush in position. While I have described in detail my improved form of the invention, it is obvious that other forms might be used without departing from the spirit and scope of the appended'claims, The recess 8 in the flange 7 straddlessome of the bristles and permits the flange 7 to be extendedso as to prevent an upward movement of the cap while at the same time permitting the auxiliary brush to be brought closely to the end of the tooth brush proper.
From the foregoing description of the various parts of the device the operation thereof may be readily understood.
The tooth brush may be used as an ordinary tooth brush forcthe cleaning of teeth. It is very diificult, however, with the ordinary tooth brush to clean a plate of false teeth, especially in the corners of the plate. By slipping the body portion 3 of the attachment over the head of the tooth brush until 1, the tooth brush is provided with a brush which will get into the corners and which will efficiently clean the plate. Furthermore, the body portion of the tooth brush itself can be used to clean the upper part of the parts have the position shown in Figure It will be seen that I have provided an auxiliary brush which may be readily attached to a tooth brush for cleaning plates of false teeth.
In Figure 4 I have showna modified form of the device. In this form the brush consists of bristles 1O on a roller 11*, which is carried on a twisted wire member 11". The roller 11 moves during the cleaning process and this t ds to" bring difierent P t ns of the brush to bearat diflerenttimes on the Object to be cleaned; thus preleng'ing the liie ofthebru'sh.
