Improvements in Needle Holding Handles, chiefly designed for use
in the Manufacture of Brushes.
I. WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
My invention relates to needle-holding handles adapted for use with brush
making machines; and has for its object to enable the operator to grip the wire
and apply the proper tensile strain thereto, in wiring the tufts of bristles in brush
manufacture.
To these ends my invention consists essentially in a clamping device composed
of a holder constructed in essentially two coinciding sections, with a peripherally
grooved pulley journalled in one section of the holder in combination with a pressure
brake set into the opposite section of the handle, and having parallel depressed
shoulders on each side of a central wire groove, adapted to receive the edges of
the opposite pulley groove; also in an arm or lever externally mounted on the
handle and fulcrumed at one end therein, and operating through a recess in the
handle to provide adjustable leverage on the pressure brake by means of manual
pressure applied thereto by the operator; also in minor details of the device
hereinafter referred to.
The sections are mounted preferably upon a handle of wood or other suitable.
In one of

said sections, is provided longitudinal and lateral recesses crossing each other, the
former serving as journal bearings, and the latter as space for the revolution of a
peripherally grooved pulley mounted on shafts, revolving in said journal bearings.
Said section is provided with a hole running through the same from end to end
immediately beneath the aforesaid longitudinal recess, to admit of the reception of
a wire passing through the end of the handle and protruding from the front thereof
after passing on its way the said peripherally grooved pulley around which it is
wrapped once or twice on its passage. The opposite section of the handle is
provided with corresponding longitudinal and lateral recesses, crossing each other;
for a similar purpose, in connection with the opposite recesses in the opposite
section of the tool.
Mounted in said last mentioned section is a lever arm pivoted therein, and having
its fulcrum upon a pin passing through the same at its forward end and into such
section. Said section is properly recessed through its exterior to permit of the
inward play of the rear end of said lever arm so that near its forward end it will
pass down through the longitudinal recess over the space provided in said section
for the revolution of the grooved pulley, and will actuate a pressure brake provided
therein when pressure is applied to the rear end of the fulcrumed lever. Said
fulcrumed lever is constructed integral with a pressure brake provided with shoulders
that may contact with the projecting edges of the groove on the pulley, and between
said shoulders is a projecting portion which fits within the groove of the pulley or

one section into the other.
By this construction I am enabled to grasp the wire firmly as it passes around
the pulley; and the lever arm operating the brake, furnishes an adjustable

shoulders on either side of the central projection, as described, prevents the wire
from slipping to either side while passing around the groove of the pulley, and
also enables the operator to obtain a firm grip thereon. In this manner the operator
holds the wire firmly by manual power applied to the lever arm governing the
pressure brake and enables all kinks to be taken out of the wire, which has never
heretofore been done by any tool of this character. My improved tool is adapted
for use in drawing wire through a brush block in connection with brush making
machines. The lower section adjacent to the wire exit passage is recessed to a
slight depth to receive the end of an eye pointed needle, which is fastened therein
by a set screw or other appropriate' means. The wire passing through the handle
is strung into the eye of the needle at the end thereof, and any ordinary mattress
needle may be used with this tool.

COMPLETE SPECIFICATION.
Improvements in Needle Holding Handles, chiefly designed for use
in the Manufacture of Brushes.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
My invention relates to needle-holding handles adapted for use with brush
making machines; and has for its object to enable the operator to grip the wire
and apply the proper tensile strain thereto, in wiring the tufts of bristles in brush
manufacture.
To these ends my invention consists essentially in a clamping device composed of
a holder constructed in essentially two coinciding sections, with a peripherally
grooved pulley journalled in one section of the holder, in combination with a
pressure brake set into the opposite section of the handle, and having parallel
depressed shoulders on each side of a central wire groove, adapted to receive the
edges of the opposite pulley groove; also in an arm or lever externally mounted
on the handle and fulcrumed at one end therein, and operating through a recess in
the handle to provide adjustable leverage on the pressure brake by means of manual
pressure applied thereto by the operator; also in minor details of the device herein-
after referred to.
In the accompanying drawing,
Figure 1 is a perspective view of my improved handle.
Figure 2 is a vertical sectional view through the line a b of Figure 1.
Figure 3 is a top view of the semi-cylindrical section in which the pulley is
mounted.
Figure 4 is a view of the combined pressure brake and lever arm detached.
Figure 5 is a top view of the semi-cylindrical section containing the pressure
brake, with the latter in position therein.
Figure 6 is a section on the line c-d of Figure 2, through the pressure brake,
and through the fulcrumed lever arm in which it is mounted or of which it forms a
part.
In
The sections A and B are mounted preferably upon a handle C of wood or other
suitable material, to enable the operator to more conveniently grasp the same.
one of said sections A, shown in top plan view in Figure 3, is provided longitudinal
and lateral recesses a and b crossing each other, the former serving as journal

page_text: bearings, and the latter as space for the revolution of a peripherally grooved
pulley D mounted on shafts d, d, revolving in said journal bearings. Said section A
is provided with a hole c running through the same from end to end immediately
beneath the aforesaid longitudinal recess a, to admit of the reception of a wire e
passing through the end of the handle and protruding from the front thereof after
passing on its way the said peripherally grooved pulley around which it is wrapped
once or twice. The opposite section B of the handle is provided with corresponding
longitudinal and lateral recesses a crossing each other; for a similar purpose, in
connection with the opposite recesses in the opposite section of the tool.
Mounted in said last mentioned section is a lever arm E shown in detail in
Figure 4, pivoted therein, and having its fulcrum
h
same at its forward end and into such section. um upon a pin passing through the
section B is properly recessed
through its exterior at m to permit of the inward play of the rear end of said lever
arm so that near its forward end it will pass down through the longitudinal recess m,.
over the space b', provided in said section for the revolution of the grooved pulley D
and will actuate a pressure brake F provided therein when pressure is applied to
the rear end of the fulcrumed lever. Said fulcrumed lever E is constructed as.
shown in detail in the several figures; that is to say, it is constructed integral with
a pressure brake F provided with shoulders ff that may contact with the
projecting edges of the groove on the pulley, and between said shoulders is a
projecting portion 9 which fits within the groove of the pulley; or said pressure
brake may be constructed as a separate element and mounted in said lever arm.
The sections are firmly fastened together by a screw n passing through one section:
into the other.
By this construction I am enabled to grasp the wire firmly as it passes around
the pulley; and the lever arm operating the brake, furnishes an adjustable leverage..
The construction of the lever arm or the brake mounted therein, with shoulders on
either side of the central projection as described, prevents the wire from slipping to
either side while passing around the groove of the pulley, and also enables the
operator to obtain a firm grip thereon. In this manner the operator holds the wire
firmly by manual power applied to the lever arm governing the pressure brake and
enables all kinks to be taken out of the wire, which has never heretofore been done
by any tool of this character. My improved tool is adapted for use in drawing wire
through a brush block in connection with brush-making machines. The lower
section adjacent to the wire exit passage is recessed to a slight depth to receive the
end of an eye-pointed needle H, which is fastened therein by a set screw t, or other
appropriate means. The wire passing through the handle is strung into the eye of
the needle at the end thereof, and any ordinary mattress needle may be used with
this tool.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1. In a needle holding handle for operating wire thread, the combination with a
holder constructed in essentially two coinciding clamping sections, and means for
mounting and conveniently grasping the same when in use, of a peripherally grooved
pulley journalled in one of said sections, which is bored out longitudinally to admit.
the passage of the wire, a pressure brake mounted on the opposite section and
having a face adapted to fit the groove and shoulders on the periphery of said
pulley, and means for actuating said pressure brake by manual pressure applied
from the exterior of the section in which it is mounted; substantially as
described.
2. A needle handle for brush making machines constructed in essentially two
coinciding sections, each of them laterally and longitudinally recessed respectively
as described, a peripherally grooved rotating pulley journalled in said recesses
respectively, a longitudinal wire passage or opening the length of the handle and
contiguous to the said rotating pulley, and a lever fulcrumed at its extreme end in

page_text: one of said sections, and adapted to act as a pressure brake on the periphery of the
pulley substantially as described.
