page_text: We. WILHELM UNGER of Wooster, Ohio United States of America, Inventor and
manufacturer of Brushes, and CHARLES MILLER, THOMAS KEARNEY, and JOHANNA
BUCKLEY, all of Wooster, Ohio, United States of America Brushmakers, do hereby
declare the nature of this invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention has reference to a new and useful method in the manufacture of
brushes and consists of the novel method of their construction by knots formed of
the stems of quills as hereinafter specified, reference being had to the accompanying
drawings and to the letters or figures marked thercon which form part of this
specification.
Fig. 1. is a longitudinal section of a brush embodying said invention. Fig. 2. is a
transverse vortical section of a brush showing its several parts. Fig. 3 is the stem of
a quill such as is used for the knots of the brush. Fig. 4 is a view of the same split
and prepared to constitute one of the improved knots for brushes. Fig. 5. is a
sectional elevation of part of a brush showing an alternative method of attaching the
quills to the block. Fig. 6, is a plan of Fig. 5 with the back removed.
Referring to the drawings, A, is one of the improved knots for brushes, which is
made by cutting off the lower or stem end of a quill and splitting the same from the
lower end upwardly into splints of suitable fineness for brush purposes, leaving the
upper end, a, unsplit. B, is the block of the brush, and similar to such as heretoforo
used. It is provided with a series of perforations, P, which are preferably made to
diminish in size from top to bottom. into each of these perforations is passed one of
the improved knots A, split into suitable splints, as aforesaid. In placing it into the
block the knot is drawn downwardly until the upper or unsplit end enters and tightens
in the perforation.
It is evident, the lower end being split, as shown, and by means of the form of the
perforation, the knot may be drawn tightly into the perforation and be there held
secure against downward movement without the use of wires or cement of any kind.
After the knots are in position, their projecting upper ends a, are cut off even with
the upper surface of the block B, and by surmounting this with the back U, tho
knots are permanently secured in the brush.

page_text: An alternative method of attaching the quills to the block B, is shown in Figs. 5
and 6, and it will be seen that the perforations P, are countersunk at p. The upper
ends a, of the quills, after being drawn tightly into the perforation P, in the manner
afore described are previously split downwards at d, and the upper ends a, of the
quills are bent over into the recesses p, as indicated at c. The back C, is then applied,
and it will be readily understood that the quills cannot possibly become detached from
the block B, by ordinary usage.
Having now described said invention: what I claim is :-
1. The brush knot A, made of the stem of a quill, having its exposed or brush ond b
split into splints of suitable fineness and having its upper end a, unsplit, substantially
as set forth.
2. In a brush, the combination with the block B, perforated, as shown, of a series
of knots, A, formed of the stem end of quills having their exposed or brush ends
split into splints of suitable fineness and their upper ends unsplit, and thereby secured
in the perforations of the block to form a brush-surface, substantially as set forth.
3. In a brush, the combination with the block B, perforated and countersunk, of a
series of knots A, formed of the stem end of quills having their exposed or brush
ends split into splints of suitable fineness, and their upper ends, drawn into the per-
forations P, split into four or more segments and bent over into the countersunk
recesses p, in the block B, all substantially as and for the purposes hereinbefore set
forth.
