Improvements in and relating to Brush Drawing Machinery.
I, GEORGE TRYON TURNER of 1705 Tioga Street, Philadelphia, United States
of America, Broker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to brush drawing machinery and has for one object to
provide simple and efficient mechanism for drawing knots or bunches of bristles
into the openings of a brush block and for securing them therein.
My improved machine comprises a novel device for holding the blocks into
which the bristles are to be inserted, and which is adapted to hold brush blocks of
different sizes; also mechanism consisting of a needle which is suitably supported
so as to loop the wire or the like for holding the bristles, through the openings in
the block. An important feature in the said needle is the provision of a clamping
piece whereby the wire or the like can be firmly secured to the needle when
desired. I further provide a novel arrangement of the drum from which the wire
or the like is drawn whereby the wire is prevented from issuing from the same
when the bristles are being secured in the brush block. I moreover arrange that
the said drum may be rotated so as to draw the wire away from the brush block
when extra force is required to draw the bristles into the holes in the same.
My improved knot picker or device for gathering the bristles into knots or
bunches of a size fitted to enter the holes in the brush block, is arranged to remove
in rapid succession knots or bunches of bristles of uniform size from a mass of stock
in a suitable hopper.
The size of the bunches can if necessary be varied and I sometimes arrange that
the device can be operated by a treadle so that the attendant can have both his
hands free for operating the other parts of the machine.
I will now proceed to describe by way of example one method of carrying my
invention into practice.
I provide a table on which is mounted a drum having journalled in it a reel
carrying a wire with which the bunches of bristles are fastened to the brush block.
Attached to the drum is a tension device which clamps and loosens the wire when
required.
The drum is connected with a treadle or foot lever pivotally attached to any
suitable support, whereby when the treadle is lowered the drum is partially rotated
and the wire clamped, the part thereof outside of the drum being drawn towards
the latter.
I provide a hollow needle which is furnished with a suitable handle and supported
by any suitable flexible support. The handle of the needle is provided with a
suitable clamp by which the wire can be clamped thereto for the purpose in some
cases of drawing the bristles through the block.
The brush block is secured in place on a slide which is horizontally movable in a
holder in a direction at right angles to the line of travel of the wire when in the
needle. The said slide is provided with adjustable plates between which the brush
block, when operated on is secured. The holder is provided with legs which pass
through the openings in the table and are vertically movable by means of a rock
shaft suitably journalled in bearings and capable of being oscillated by an arm
thereby raising or lowering the holder.
I provide suitable means for securing the said holder in place.
To properly size the bunches of bristles so that a uniform number can be taken
for each bunch or knot, or a quantity corresponding to the size of the opening may
be selected, I sometimes use the following mechanism.

page_text: I provide a block having a groove for receiving a quantity of the bristles the
said block is adjustably secured to a suitable standard.
To obtain the proper
quantity of bristles from the bunch which may be presented to said block, a
conically pointed divider is provided, the same being movable in bearings in the
upper end of the standard and adapted to close the front entrance to the groove in
the block. The said divider is operated by a pivotted lever which can be oscillated
so as to open and close the entrance to the grooves in the block, the size of the
bunch of bristles held when the divider is in front of groove being determined by
the position of the block which forms one end of said groove. I provide also a
pair of shears arranged to be operated by a suitable handle.
The drum which contains the reel of wire may be formed with a projecting
portion or flange on its side adapted to abut against a rubber or elastic cushion or
buffer so as to prevent any jarring or concussion to machine from the movements
of said drum, as well as to limit the play of the latter.
I provide the reel with a tension device to prevent the same from revolving any
faster than the delivery of the wire from the drum, and thereby avoid any buckling
or bending of the wire in the drum.
Instead of the knot picking device above described I prefer to use an improved
knot-picker constructed after the manner following.
The frame of the knot-picker is formed in two halves secured together by
suitable transverse bolts the upper portion of each of these sides having a laterally
projecting segmental web which forms one of the sides of the hopper or receptacle
for receiving the bristles or other stock from which the brush is to be made.
The other side of said hopper or receptacle consist of plates held in proper
relation to the above-mentioned webs by means of curved arms or braces removably
secured to the body of the machine.
The stock is pressed down into the bottom of the hopper and into contact with
the front portions of the side plates by means of a plunger which is pressed forward
by a spring or other suitable device and which can be withdrawn whenever a new
supply of stock is to be introduced. I may arrange that the pressure on the
plunger and therefore on the many bristles in the hopper may be varied if
required.
The inner portion of the segmental webs are cut away at a point adjacent to the
front plate and to the backs of the webs is secured a spring the free end of which
covers the opening thus formed.
The front plates of the side frames are slightly separated so as to form a slot to
receive a slide which is connected to a treadle or other appropriate operating
device, whereby the slide may be caused to rise and fall on the frame.
A curved knife is pivotally secured to the inner side of the slide which projects
through the slot in the front plate, and is controlled by a suitable spring and I
arrange that when the slide is in a position away from the mass of bristles the knife
is drawn inwards and is held in the retracted position until the slide again approaches
the mass of bristles whereupon the knife is again projected into the said mass.
Projecting from the front of the before mentioned slide is a block from which
projects upwardly a second knife and between this knife and the front of the slide
is guided a follower which can be adjusted at any suitable distance along the said
second knife.
I also provide a convenient means of preventing any bristles becoming separated
from the mass when the slide is withdrawn carrying the proper sized bunch away.
The size of the bunch being determined by the position of the follower relative to
the knives.

Improvements in and relating to Brush Drawing Machinery.
I, GEORGE TRYON TURNER, of 1705 Tioga Street, Philadelphia, United States
of America, Broker, 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 :-
My invention relates to brush drawing machinery.
One part of my invention relates to a needle for looping the wire or the like for
holding the bristles through the openings in the block. An important feature in
the said needle is the provision of a clamping piece whereby the wire or the like
can be firmly secured to the needle when desired.
Another part of my said invention relates to an improved knot picker or device
for gathering the bristles into knots or bunches of a size fitted to enter the holes
in the brush block. By means of this knot picker knots or bunches of bristles of
uniform size can be removed in rapid succession from a mass of stock in a suitable
hopper. The size of the bunches can if necessary be varied and I arrange that
the device can be operated by a treadle so that the attendant may have both his
hands free for operating the other parts of the machine.
In order that my invention can be more easily understood I will now proceed to
describe the same by the aid of the accompanying drawings in which,
Figure 1 is a view of one form of my improved needle suspended from a
support.
Figure 2 is a detail view of part of Figure 1.
Figure 3 is a view of another form of my improved needle.
Figure 4 is a perspective, and
Figure 5 is a sectional view of my improved knot picker.
Referring now to Figures 1 and 2 my improved hollow needle is provided with a
suitable handle A, and supported by the coil springs B B, attached thereto and to
a standard C mounted on a suitable stand. The said springs B furnish a flexible
support for said needle, permitting it to be freely moved in any desired direction.
D is the wire passing through the needle and with which the bristles are to be
fastened into the brush block.
The handle A of the needle is provided with a clamping lever A' adapted to
engage and hold the wire D in the needle when necessary or the handle itself may
be divided and hinged in an obvious manner to engage and hold the wire D.
The operation of the needle is as follows:-The end A* of the needle is passed
through an opening in the brush block so far that its front end with the wire
projects beyond the said block. The needle is then drawn back, this may be done
by simply releasing the handle, which being of a weighty material causes it to
leave the opening. The wire, which passes freely through the needle, is not with-
drawn from the opening, by the retraction of the needle from the brush on the
opposite side from the needle, but remains projecting in the form of a loop, in
which a proper quantity of bristles is placed. The said wire is then clamped in the
needle and drawn back so as to force the bent portion of the bristles into the
opening in the brush block thereby securing the same firmly therein.
In Figure 3 a needle is shewn having its handle of a slightly different shape to
that shewn in Figures 1 and 2, and which is not slung or attached to any support
when in use.
The wire clamping device on this needle comprises a pivoted lever A³ adapted
when pressed towards the handle A; to force a pin A* inwards and clamp the wire.
When the lever is not operated the. pin A is withdrawn from engagement with the
wire by the spring A'.
My improved knot picker is shewn in Figures 4 and 5. It formed in two

page_text: halves E E' secured together by suitable transverse bolts e, the upper portions of
each of these sides E, E', having a laterally projecting segmental web el which
forms one of the sides of the hopper or receptacle F for receiving the bristles or
other stock F from which the brush is to be made.
The other side of said hopper or receptacle consists of plates G G¹ held in
proper relation to the webs e' by means of curved arms or braces. The lower
brace is rigidly secured both to the webs e¹ and to the plate G, but the upper
brace is furnished with a suitable clip or clips for engaging or releasing the edges
of the webs e¹ the upper plate G being hinged at G to the lower plate G, so that
it can be thrown down as shewn in dotted lines in Figure 5 it when it is desired to
introduce a fresh supply of stock into the hopper.
The stock is pressed down into the bottom of the hopper and into contact with
the front portions of the side plates E, E by means of a plunger H which is
carried by an arm or arms H' partly curved and partly straight, the curved portion
of the arm being concentric with the curved or segmental hopper, and the arın
being pivoted by a rock shaft at the centre of the curve followed by the hopper,
so that the plunger is free to move up and down in the hopper and will press the
stock down towards the bottom of the hopper, or can be withdrawn whenever a new
supply of stock is to be introduced.
The rock shaft carries a screw-stem ', at the inner end of which is a cross-
head-2, which embraces the straight portion of the arm H', and is acted upon by a
spring tending to draw said arm forward and thus cause the plunger to move
downward in the hopper, the pressure upon the plunger being varied by manipulating
the screw stem so as to carry the cross head 2 nearer to or further from the rock
shaft h, so that any desired degree of pressure can be imparted to the stock in the
hopper. His a needle moving in suitable guides and joined by a pin to a
lever which is pivoted on the plates E E' at H³. The other end of said lever is
joined by a link 1 to the rod hereinafter mentioned. The rod H also carries a
projecting arm fls having a slot at the end thereof adapted to engage with the
arm H which is secured to or forms part of the arm H' so as to draw the plunger H
away from the stock F against the force of the spring when required.
The inner portion of the segmental webs el are cut away at a point adjacent to
the front plate e as shewn at F and to the backs of the webs is secured a spring e³,
the free end of which covers the opening thus formed, as shown in Figure 5.
The front plates e² of the side frames of the machine are slightly separated so as
to form a slot in which is guided a slide I, which is connected by a rod i to a treadle
or other appropriate operating device, whereby the slide may be caused to rise and
fall on the frame.
Projecting from the front of the slide is a block from which projects upwardly
a knife and between this knife and the front of the slide I is guided a follower J
which has a stem j projecting through the block it and carrying at the lower end a
nut adapted to a screw stem j the upper end of which is swivelled in said block i¹
so that by turning said stem the follower J may be raised and lowered.
Hung to a bracket on the inner side of the slide I is an arm K, the upper end of
which is bent forward so as to constitute a knife k which projects through the slot
in the front plate e³, and is normally held in contact with the upper end of the
knife by means of a spring / bearing upon the back of the arm K.
A pin projects laterally from the arm K, however, and when the slide is raised
this pin is acted upon by the lower end of a cam plate L secured within the frame
of the machine so that the knife is drawn inwards and is held in the retracted
position until the pin 7 passes upward beyond the cam plate L, whereupon the knife
is again projected by the action of the spring kl.
On the downward movement of the slide the lower end of the cam plate L, which
is elastic, yields inwardly when the pin is moving along the front of the same, and
again springs forward after the pin has passed it.
Projecting downward from the plate G is a bracket M in the upper portion of
which is guided a finger M' having a downwardly projecting tongue m, and to the

page_text: lawer end of the bracket M is hung a bell crank lever N the upper end of which is
adapted to act upon said tongue m while the lower arm of the lever projects into
the path of the block on the slide I as the latter is raised.
The finger M is acted upon by a spring m¹ tending to project it, and the lever N
is prevented from falling below a certain point by coming into contact with a
supporting spring n as shown.

In order to fill the hopper with bristles the upper plate G¹ is turned back as
shewn in dotted lines in Figure 5 and the plunger H is lifted. The bristles are
then inserted with their ends in contact with a plate O which forms the back of the
hopper; the said plate O is supported on screws ou screwed through the braces fƒ³,
and by operating the said screws, the plate may be screwed into and out of the
hopper so that the place where the bristles are caught by the slide may be adjusted
as desired. I sometimes arrange the plate O on the opposite side of the machine
to that on which it is shewn in the drawings or I may use a plate on both sides of
the hopper.
Having thus described the construction of the device I will now proceed to
describe the operation of the same in picking successive knots or bunches of bristles
or other stock from the mass in the hopper or receptacle.
The follower J is first adjusted to such a position in respect to the knife k that
the distance between the upper end of the follower and the knife will be just
sufficient to contain a knot or bunch of the stock of the proper size. On the
upward movement of the slide I the pin upon the arm K is so acted upon by the
cam plate L as to withdraw the knife k, as shewn in Figure 4, and as the movement
of the slide continues the block, strikes the lower arm of the lever N and causes
its upper arm to act upon the tongue m of the finger M so as to retract the same
just before the upper end of the knife reaches it.
It should be understood that the lower portion of the plate G is cut away
adjacent to the plate e of the frame, so that the finger M' when projected, serves
as the support for the bristles in the lower portion of the hopper.
When the finger M' is retracted therefore, the knife and follower J can be
thrust into the mass of stock in the lower portion of the hopper, the frame end of
the spring bearing upon the mass of stock in the line of thrust, so that said spring
can yield and thus permit the free entrance of the knife and follower into the mass
of stock. Also the needle H is operated by the treadle through the rod i and
lever so as to be driven into the mass of stock in the hopper as shewn in
Figure 5, this prevents the plunger from pressing the stock together so hard as to
hinder the knife and follower J from being thrust far enough into the stock F'.
At the same time by the action of the arm H, the plunger H is drawn away from
the mass of stock in the hopper thereby allowing the bristles to part and perimit the
entrance of the needle H2 between the same.
As soon as the pin of the arm k passes the top of the cam plate L, the knife k
is thrust forward by the action of the spring, so that a bunch or knot of bristles
is caught and confined between said knife k and the follower, and on the descent of
the slide I this knot or bunch is withdrawn from the mass in the hopper.
As the slide I descends the block engages with the lever N and permits the
finger M to move forward under the action of the spring m³, the front end of the
finger sliding along the top of the knife k so as to again close the opening in
the plate G, and thus prevent the escape from the hopper of any of the stock other
than that constituting the knot or bunch which is carried by the slide.
On the descent of the slide the pin l trips the lower end of the cam plate L, and
the latter then springs back into its former position so as to act upon the pin, when
the slide is again raised.
A device of the character described provides for picking knots or bunches of
uniform size, in rapid succession from the mass of stock in the hopper, the size of
the bunches depending upon the adjustment of the follower J. The said device
can be worked by a treadle or other foot power movement, so that it can be
operated simultaneously with a brush drawing machine, the attendant removing a

page_text: knot or bunch of stock from the picker with one hand while he is applying another
knot or bunch of stock to the brush block with the other hand.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A needle for use in the manufacture of brushes having a tubular part through
which the binding wire passes in combination with a clamp for nipping the said
binding wire, substantially as described for the purpose specified.
2. In a knot picker for sizing bunches or bristles a sliding part for withdrawing
the knots or bristles or the like from stock, said sliding part being furnished with
two knives one fixed thereto and the other pivoted thereon, and means for
controlling the pivoted knife substantially as, and for the purpose, specified.
3. The device, by means of which I prevent bristles escaping from the hopper
after the bunch has been withdrawn from the same, substantially as described.
4. The device for controlling the pivoted knife whereby it is maintained out of
contact with the fixed knife when the said knife is moving towards the stock, but
is pressed towards and kept in contact with the same when a bunch of bristles is to
be withdrawn from the hopper, substantially as described.
5. The improved needles constructed substantially as described with reference to
Figures 1 and 2 or to Figure 3 of the accompanying drawings, and operating as,
and for the purpose specified.
6. The improved knot picker constructed substantially as described with
reference to Figures 4 and 5 of the accompanying drawings and operating as
specified.
