Year: 1880

page_text: LETTERS PATENT to Edward Wright, of Lower Sydenham, in the County of
Surrey, for an Invention of "IMPROVEMENTS IN APPARATUS FOR FORMING
OR SECURING THE KNOTS OF BRISTLES IN THE MANUFACTURE OF BRUSHES."
PROVISIONAL SPECIFICATION left by the said Edward Wright at the Office
of the Commissioners of Patents on the 18th December 1880.

MENTS IN APPARATUS FOR FORMING OR SECURING THE KNOTS OF BRISTLES IN
THE MANUFACTURE OF BRUSHES."
"
IMPROVE-
My Invention relates to improvements to be applied to screw presses employed
in the manufacture of paint brushes and other like brushes, whereby the operation
of forming or securing the knots of bristles is facilitated, and my Invention is
applicable in cases where the knots of bristles are bound or secured by means of
clips such as are described in the Provisional Specification accompanying my
application for Letters Patent dated the 22nd October 1880, No. 4319.
In carrying out my Invention I construct the die of the press in two halves as
heretofore, and through the wall or side of one of such halves I form a slot to
admit of the protrusion of the end of the clip. I also form an aperture for the
insertion of a key which is split at its extremity so as to be capable of engaging
with the end of the clip.
In using this apparatus the knot of bristles to be bound is placed in the die
with the metal strip which is to form the clip encircling the same, one of the ends
of the strip being caused to engage with the other, and to protrude through the
slot in the die. The key is next inserted in the aperture in the die so as to lay
hold with its split portion of the protruding end of the strip, and is then turned by
the operator with one hand whilst he works the screw of the press with the other.
By these means the strip is tightly bound round the knot without the liability of
kinking, and on the removal of the knot so bound the protruding end of the clip
is bent back and pressed down, and the operation is complete, the knot being then
ready for insertion in a stock of any suitable description.

IMPROVE-
MENTS APPLICABLE TO PRESSES EMPLOYED IN THE MANUFACTURE OF BRUSHES,
FOR THE PURPOSE OF FORMING OR SECURING THE KNOTS OF BRISTLES."
My said Invention relates to improvements to be applied to screw presses
employed in the manufacture of paint brushes and other like brushes, whereby the
operation of forming or securing the knots of bristles is facilitated, and my Invention
is applicable in cases where the knots of bristles are bound or secured by means of
clips such as are described in the Specification of former Letters Patent granted to
me dated the Twenty second October, One thousand eight hundred and eighty,
No. 4319.
In carrying out my present Invention I construct the die of the press in two
halves as heretofore, and through the wall or side of one of such halves I form a
slot to admit of the protrusion of the end of the clip. I also form an aperture for
the insertion of a key which is split at its extremity so as to be capable of engaging
with the end of the clip.
In using this apparatus the knot of bristles to be bound is placed in the die
with the metal strip which is to form the clip encircling the same, one of the ends
of the strip being caused to engage with the other, and to protrude through the slot
in the die. The key is next inserted in the aperture in the die so as to lay hold
with its split portion of the protruding end of the strip, and is then turned by the
operator with one hand whilst he works. the screw of the press with the other.
By these means the strip is tightly bound round the knot without the liability of
kinking, and on the removal of the knot so bound the protuding end of the clip is
bent back and pressed down, and the operation is complete, the knot being then
ready for insertion in a stock or handle of any suitable description.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same, and for that purpose shall refer to
the several Figures on the annexed Sheet of Drawings.
Figure 1 of the accompanying Drawings represents a perspective view of a press
constructed and arranged according to my said Invention so as to adapt it for
binding the knots of bristles; and Figure 2 represents one of the metal strips
employed in the formation of the clips according to my former Invention, as
described in the Specification to my said former Letters Patent.
In carrying out my said former Invention, the knots of' bristles were bound in
metal strips, an example of which is shewn at F, Figure 2, the said strip being
caused to encircle the knot of bristles, and having its two extremities f,f¹, threaded
together so as to form a clip. In order to facilitate the binding operation, I
employ a press and appliance, constructed and arranged in the manner shewn in
Figure 1.
The die of the press is constructed in two halves g, g', as heretofore, and through
the wall or side of the upper half g is formed a slot g² to admit of the protrusion of
the end f¹ of the clip. An aperture g³ is formed at right angles to the length of
the slot g² for the insertion of a key g, which is split at its extremity 95, so as to be
capable of engaging with the end f¹ of the clip.
In using this apparatus, the knot of bristles B to be bound is placed in the die,
as shown in Figure 1, with the metal strip which is to form the clip encircling the
same, the end f¹ being caused to engage with the perforated end of the metal
strip, and to protrude through the slot g² in the die, as shown. The key g¹ is next

page_text: inserted in the aperture in the die, so as to lay hold with its split portion at go of
the protruding end of the strip, and is then turned by the operator with one hand
whilst he works the screw G by the handle G' with the other. By these means the
metal strip is tightly bound round the knot of bristles without the liability of
kinking, and on the removal of the knot so bound the protruding end f¹ of the
clip is bent back and pressed down, and soldered and the operation is complete.
Having now described and particularly ascertained the nature of my said
Invention and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention secured to me by the hereinbefore in part
recited Letters Patent is,-
The combination with the die of a press, of a key or appliance for tightening the
clip when the said parts are arranged and combined together, substantially in the
manner and for the purpose, herein before described and as illustrated in the
accompanying Drawings.
In witness whereof, I, the said Edward Wright, bave to this my Specification
set my hand and seal, this Twenty sixth day of May, One thousand eight
hundred and eighty one.
EDWARD WRIGHT. (L.S.)
