EDWARD I1. CHO'IT, OF CHICAGO, ILLINOIS, ASSIGNOB OF ONE-HALF TO HUGO J. CHOT'I, OF CHICAGO, ILLINOIS.
BRUSH.
Specification of Letters Patent.
Patented Apr. 25, 1916.
To all whom it may concern:
Be it known that I, EDWARD L. CHo'r'r, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Brushes, of which the following is a specification.
My invention relates to improvements in brushes and has for its object the provision of an improved brush especially adapted for dental purposes.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed.
The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which- Figure 1 is a sectional view of a brush embodying my invention and shown at an early stage of the manufacture, Fig. 2, a sectional view of the brush at a later stage of manufacture, and Fig. 3, a sectional view of the completed brush.
The preferred form of construction as illustrated in the drawing comprises a me tallic ferrule 1 having a reduced portion 2 which is snugly and tightly fitted over the stem 3 which constitutes a means or handle for mounting the brush in a dental tool. In completing a brush, a bundle of bristles 1- is bound together centrally by means of a cord or wire 5 the ends of which are knotted together as at 6. The bristles are laid across the open end of ferrule 1 and the centrally bound portions of said bristles are forced into said ferrule by doubling the bristles as indicated in Fig. 2. Then the outer portion 7 of ferrule 1 is contracted upon the bristles by means of swaging or other suitable means to tightly engage the bristles as indicated in Fig. 3, said contraction of said ferrule forming an enlarged portion 8 for the accommodation of the folded portion of the bristles, the binding 5 and the knot 6. It will be observed that the knot 6 is arranged to be included within the fold to produce bristles thus tending to spread the fold. By
this construction and method of procedure the bristles will be tightly bound in the ferrule so that it is practically impossible to remove the bristles.
The construction and method of procedure constitutes a simple and economical one for the purpose and thus results in the economical production of a brush of great durability.
While I have illustrated and described the preferred form of construction and the preferred method of procedure, these are capableof variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction and the precise method set forth, but desire to avail myself of such variations and modifications as fall within the scope of the appended claims.
I-Iaving described my invention what I claim as new and desire to secure by Letters Patent is:
1. A brush comprising a ferrule having an inner enlargement and a contracted outer portion; and bristles bound together centrally by a knotted binding and folded at said binding with the knot within said fold, said bound portions being secured in said enlargement and said bristles projecting through said contracted portion, substantially as described.
2. A brush comprising a ferrule having an inner enlargement and a contracted outer portion bristles bound together centrally by a knotted binding and folded at said binding with the knot within said fold, said bound portions being secured in said enlargement and said bristles projecting through said contracted portion; and a stem secured in the other end of said ferrule, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
EDWARD L. CHOTT.
