Improvements in Machines for Manufacturing Brushes and
the like.
I, HEINRICH FRIEDRICH REINOLD, of Hamm, in Westphalia, in the Empire
of Germany, Manufacturer, 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 relates to an improved machine for the manufacture of brushes
and the like by which the bundles of bristles, automatically supplied, are clamped
to the wooden back of the brush by means of wire clamps or staples also
automatically made and supplied by the machine.
In order that the nature of my invention may be more readily understood I have
hereunto annexed a sheet of drawings illustrating the new or improved machine, in
which Fig. 1 is a front elevation of the same and Figs. 2 to 9 represent details part
of them being shown in an enlarged scale.
The wire a serving for the manufacture of the clamps or staples is held on a
disc c which is turnable on or around the vertical shaft or bolt b and provided for
the said purpose with pins d. The wire a passes from the coil under click e on and
through the guide g secured to the framework f and thus after passing the slide or
latch reaches the cutter, by means of which the length of wire required for the
formation of a clamp or staple is cut off. The slide h receives a horizontal
to and fro movement through double-armed lever k which is fulcrumed at i, whereby
the slide is moved in the guide of the framework f. The swinging movement
of double-armed lever k is effected by means of a sleeve n having a curved groove
and being secured on the shafting in, while the reach of the lever k is exactly
regulated in accordance with the size of the wire clamps or staples required, by
means of set-screws o provided in the slide h. The spring click p connected with
the said slide carries the wire a along with it to the left upon slide h being moved
in that direction (Fig. 3). On the wire being moved a sufficient distance towards
the left the rod is pressed down upon the tail of click p by means of a
projection provided on sleeve n. The click p is thereby disengaged, the slide h is
moved backwards by lever k, while click e prevents the wire a from being carried
along.
The piece of wire a pushed forward by slide h and separated from the coil
by the cutting device now occupies the position illustrated in Fig. 4, and is then
formed into a V shaped staple or clamp by lever r (vide Fig. 5) attached to a
square part of shaft s. Another lever is provided in the immediate proximity
to lever r, giving through and in connection with shafts and pushing rod u a
turning movement necessary for bending the wire. For this purpose the upper
portion of pushing rod u connected to head vis formed into a loop. On the other
side of head va pin is provided, which, with the up and down movement of the
said head piece, effected by crank y and connecting rod x, actuates the knife or
cutter z to cut the wire a gliding along lever c¹ which moves on pivot a¹ and is
acted upon by spring b¹.
The regular supply of the required quantity of bristles is effected in the following
manner :-
The material contained in receptacle d' is pressed towards the feeding aperture
by flap f, which is pivoted at e¹, whereby the action of pusher g', which is
influenced by a spring h¹ and laterally displaced from hinge m³, the material is
delivered to the toothed bar serving for moving it forward. A to and fro and

page_text: up and down movement is imparted to the toothed bar for the purpose of
effecting the moving forward of the material. The to and fro movement of the
said bar is caused by the double-armed lever ', guided at its upper end by disc k',
in such manner that it actuates the lever n¹ through lever m¹ whereby n' is placed
against projection o¹ which is connected with the toothed bar moving the latter
towards the right, while the retrograde movement of the bar is effected by a helical
spring p'. The up and down movement of toothed bar is caused by lever r¹
actuated by pin q', of shaft m the lower extremity of lever being bent to form
an angle which passes under the bar. Upon contact taking place between pin
and lever ¹, the latter oscillates on its fulcrum s¹, thereby raising bar i¹ (Fig. 2)
while spring effects the return of the latter to its original level. Above the
toothed bar a passage t¹, forming a continuation of receptacle or hopper d¹ and
serving for carrying forward the material, is provided, through the bottom of which
the teeth of bar enter into the material contained therein at each upward move-
ment of the bar, and at the subsequent horizontal displacement of the latter
towards the right, the material is carried along. When the final stage has been
reached the teeth of the toothed bar automatically recede from the material and
the bar itself is returned to its original position through the contraction of helical
spring p. The before described process is subsequently repeated with each
revolution of the driving shaft m.
By the action of a separating or dividing device v¹, sliding in vertically arranged
guide u', Fig. 4 the exact quantity required is separated from the material arrived
at the end of channel t¹ and taken up by the gripper w¹. The separating or
dividing device is actuated by means of crank disc ¹, provided on shaft m, said
crank communicating its stroke to two-armed lever 62, fulcrumed at a², through
connecting rod 2 which carries at its lower end the cross-joint y'. The lever b² is
connected with the separating or dividing device by joint e, effecting at each
revolution of the shaft an up and down motion of v. Two-armed lever further-
more actuates the gripper w¹ provided in the rear portion of the machine, a slotted
rod d acting on lever 2 having its fulcrum at 2. Said lever f is in direct and
turnable connection with gripper w which slides in a vertical guide, and thus
produces an alternate up and down motion of the gripper, whereby, when the
gripper is on the descend the material taken up by it is carried through
channel u towards the horizontally arranged channel 2. In order to prevent
gripper w from passing beyond the lower edge of channel 22, a projection f³ is
provided on the frame for the purpose of confining the upward oscillation of
lever within the requisite limits. The material is carried from the lower end of
vertical channel u' through channel into the stamping box 2 for which purpose
the pushing rod 12 serving to move the material is connected by pin m² to rod n².
The latter is connected to lever q', fulcrumed at p2 and actuated through curve-
grooved sleeve o² and thus communicates a to and fro motion to the pushing rod 12,
which has at its other end a slot t2 adapted to receive the pin 2 provided on u²
during their movement towards the left from n², to leave a wider space between
each other, while during their movement towards the right the part u² is pushed
through and the intervening material. A drag-spring w³ is provided for the
purpose of preventing a spontaneous retrograde movement of u².
This movement
The stamping or clamping box consists of two portions, and has a vertical
slot 2 in which the cut-off end of wire is being held. The bending of the wire
into a clamp or staple is effected, as herein before described, by thumb piece r held
on shafts and put into oscillating motion by lever t and rod u.
pushes the thumb r into a correspondingly shaped recess of the stamping box,
and to enable the thumb piece to enter into the depth of said recess, the end part
of the latter is bevelled out and a plate y2 provided within the bevel and pressed
forward by spring leaving the sides of the guide flush and smooth for the
passage of the U-shaped cramp or staple. A stamp or plunger a³ (vide Fig. 9) is
provided within the vertical slot a2 and secured at its upper end to the headpiece v
thus receiving from the latter an up- and down-motion. In descending the

sponding portion of the staple, upon the latter, pushing it downward and causing
the ends of the cramp or staple to embrace or clasp the material, whereupon both,.
cramp and material, are pressed by the said plunger a³ through channel 63,.
provided within the stamping case or box, into the wooden brush stock.
The complete machine is actuated by belting on pulley which is secured to
one half of a clutch coupling while the other half of the latter is connected with a
lever d³ to be worked by the attendant with his foot, to engage or disengage the.
coupling.
The machine hereinbefore described in detail works in the following manner :-
Supposed a bunch of material had just been secured to the brush stock by
wire cramps or staples, and another bunch was lying ready at the lower aperture
of the vertical channel u¹, the headpiece would be in its lower-most position.
Consequent upon the ascent of the head piece the wire supplying device is
actuated through crank disc n, and the piece of wire required for the formation of
When the headpiece has attained its
a cramp is delivered into the stamping box.
highest position, the pin w provided at the head piece operates the cutter lever
whereby the piece of wire introduced into the stamping box is separated from the
coil. The thumb piece r simultaneously enters the said box, bending the piece of
wire into a U shaped cramp or staple. The head piece then moves in a downward:
direction while the bunch of material lying ready in the lower part of channel ¹ is
carried into the stamping box by the combined action of curve-disc o and lever q².
Upon the further descent of the head piece the plunger a³ presses on the previously
finished wire cramp, returns the lever to lower position and pushes the shanks of
the wire cramp over the bunch of material, and drives cramp and material out of
the stamp box into the wooden brush stock. The principal material-supplying
device is operated by part 1, connected to bolt m² and pusher g' the latter receiving
a swinging motion.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
(1.) A machine for the manufacture of brushes wherein the wire supplied by a
special contrivance is cut into pieces of the length required and formed into a
V shaped cramp, clutch, or staple whereupon the shanks of the latter are made to
embrace an automatically supplied bunch of material bristles or the like, and is
then, together with said bunch, pressed into the wooden brush-back or stock.
(2.) In a machine forming the subject of Claim 1, a wire-supplying device
whereby the wire a wound off from coil is moved forward by a pusher (4) actuated
from a curve-grooved sleeve (n) whereupon, when the wire has been moved the
distance required, the click (p) effecting the forward movement of the wire, is
disengaged by a peg or pin (g) and upon the return movement of the pusher (h) a
stop click (e) prevents the wire from being carried along.
(3.) In a machine forming the subject of Claim 1, a device or apparatus for
separating and conveying material supplied from a store receptacle or hopper (d')
5 by the action of a wing or flap (f) and a pusher (g) in layers of equal thickness
into a horizontal channel (t), wherein it is moved along by a toothed bar (¹) in a
horizontal direction, then passed, by the action of a dividing device (v) and a
gripper (wol), into and through a vertical channel (u') and finally into a second
horizontal channel (2), whence a pushing rod (2) conveys it into the stamping
box (k2).
