A communication from THE WILLARD & FRICK MANUFACTURING COMPANY, (a
corporation created and existing under and by virtue of the laws of the
State of New York) doing business at Rochester, New York.
I, ALFRED JULIUS BOULT of 111 Hatton Garden in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
--
The present invention has for its object to provide a machine for barbing and
cutting metal wire for forming the bases of cleaners for tobacco pipes, which
cleaners consist of a suitable length of wire having upon each end two series
of barbs or projections extending in opposite directions, and a covering of fibrous
material, such as absorbent cotton, held in position by the barbs and prevented
from longitudinal and rotary movement on the wire as the cleaner is pushed and
pulled through the pipe stem to clean it, and the invention consists in certain
imechanism and devices hereinafter described, the novel features being pointed
out in the claims at the end of this specification.

A indicates the main frame of the machine preferably mounted upon the table
or support A and having at one side a guide or way A2 in which operates a wire-
feeding slide or carriage B, and at the other end of said way are wire straightening
devices embodying rollers or pins a, a¹ of the usual or any preferred construction,
through which the wire to be operated upon passes, before it is fed between the
dies which form the barbs thereon.
The dies for operating upon the wire are each composed, preferably, of a series
of removable knives or teeth C. (see Figure 12) hold in
L
1*

page_text: blocks C¹ by bolts C having sleeves c¹ and nuts thereon, as in Figure 4, and
the faces of the teeth Care inclined and the side undercut, as at c³, for the
purpose of enabling the barbs to be more readily turned up on the wire and
the dies are so moved by the devices hereafter described that they approach
each other and move laterally in opposite directions causing barbs or teeth to
be turned up on opposite sides of the wire, as in Figure 13. On the opposite
side of the main frame from the feeding devices is arranged a wire guide D
through which the wire passes and is guided to a cutter embodying the stationary
knife edge D1 and the movable knife 12 mounted on a lever D³ pivoted upon a
bracket on the frame.
The wire feeding devices referred to embody the reciprocating slide or
carriage B connected by a link to the end of a lever B2 pivoted at b, the other
end of the lever being connected by a link 13 with an adjustable wrist pin 1
on a wheel or disk B. On the front of the slide are arranged two wire grippers,
each consisting of a collar 63 having a roughened edge and surrounding a boss b
to which is connected a spring frictionally engaging the collar b³ and tending
to move it to the right and beneath an incline 65 and clamp the wire W between
the collar and a support 66.67 indicates a bar sliding in guides on the carriage B
and having pins 68, which, when the bar is moved to the left, will disengage the
grippers from the wire; and b is a lever pivoted on the slide and engaging
the bar, its lower end being arranged to strike adjustable stops 10 on the slide
frame, as the slide is reciprocated to permit the engagement and cause the dis-
engagement of the grippers. c indicates a wire gripper similar to the ones
on the slide located on the stationary frame and co-operating with an incline 6
and released by a pin on a pivoted lever c, the upper end of the lever being
engaged by a pin co on a sliding rod to which are attached stops c12, 13,
adapted to be engaged by a lug 612 on the slide. A friction spring c pressing
on the rod el prevents accidental movement.
The operation of the wire-feeding device is as follows:-
When the slide is in the position shown, the grippers upon it are caused by
their springs to engage the wire, while the stationary gripper c is disengaged
by the stop on the lever c, which latter is moved to the position shown in
Figure 9 by the rod c. As the slide is moved by the lever toward the dies,
after the barbs have been formed on the wire between them, the grippers thereon
draw the wire through the straightener and push the barbed portion through
the guide D, the movement being sufficient to bring the middle of said barbed
portion between the cutters D', 12. As soon as the slide B reaches the end of
its guide, the lug 62 engages the stop c, moves the rod e permitting the engage-
ment of the gripper with the wire, and the lever engaging the stop 610 dis-
engages the grippers on the slide from the wire, thereby allowing the slide to
move back while the wire is held. The cutter is operated to sever the wire
and the barbing dies are operated while the slide is moving outward.
Various mechanisms may be employed to cause the operations described, but
in the present embodiment of this invention, the die blocks C are arranged to
slide laterally upon suitable ways E, E, formed on the front of slides E, E
movable in vertical ways formed in the front of the main frame, as shown
particularly in Figures 5 and 6, adjusting screws and plates e, e¹ being provided
for taking up any lost motion between the blocks and slides and the slides and
main frame. The slides E, E are each provided with a large central recess
through which pass the shafts F, F, journaled in the main frame and also in
yoke brackets F2, F2 and upon said shafts are arranged intermeshing gears F3, F4
for operating them simultaneously, the upper gear F3 meshing with a gear F5
on the shaft Fe carrying the disk 14.
Arranged between the slides E, E are one or more springs E3 tending to
separate them, and their outward movements are limited by stops E3, while
within their central recesses are brackets E, E, carrying rollers E5, E5 on
eccentric pins E6, E, the bracket in the lower slide being located on the upper

page_text: side of the recess, and the one in the upper slide in the lower side thereof, and
upon the shafts F, F are cams G, G, shown in Figures 5 and 7, against which
the rollers on the slides are held by the springs E2, said cams operating to cause
the approach of the slides at certain times. Also arranged upon the shafts F, FI
are cams G¹, G¹ co-operating with rollers E7, E7 on studs E8, E8 arranged on
the fronts of the die blocks C¹, C and on opposite sides of the shafts, as in
Figure 4, said die blocks being moved laterally on the slides E, but in opposite
directions by the springs H, H, while their movement is limited by adjusting
screws H, H, these springs serving to keep the rollers on the blocks in engage-
ment with the cams. The cams and their operating rollers are so relatively timed
and arranged that as the shafts revolve in opposite directions, the cams G will
cause the approach of the slides until the teeth of the dies engage the wire
between them and then the cams G¹ will cause the lateral movements of the die
blocks C¹ on the slides in opposite directions, the teeth of the dies turning up
the barbs on the wire, as previously described, and it will be understood that,
at the same time, the dies are also moved together by the cams G to cause the
proper shaped barbs to be turned on the wire. The eccentric pins E, E may
be rotated to vary the amount of the movement of the slides and are secured
in adjusted position by small screws in the brackets E4, which operate against
the split spring sleeve e', said sleeve being clamped to the pin, and held by the
screw entering a depression in the slide, as shown in Figure 11.
In a machine of this class, instead of drawing the wire directly from the reel
containing it, it is desirable to provide a sufficient amount of slack wire to be
taken up at each reciprocation of the feeding device, and with this idea in view
and also of providing for the unwinding of the proper amount from the reel, a
loosely supported wire reel J upon the base A' is provided from which the wire
extends through an aperture in a guide pin J¹ secured to a support J2 by a
small screw, and mounted upon said support is a shaft having a conical friction
driving pulley K thereon and a gear K₁ meshing with the gear F³. K² indicates
a small cone pulley mounted upon a stud K on the support J2 and the wire W
from the reel extends through the guide J around the cone pulley K against
which it is held by the idler cone K2, through a guide J, preferably beneath
the table, thence through a guide J to the wire straightener before described.
As the pulley K is positively driven, the wire is drawn off the reel in just
sufficient quantity to provide the necessary slack and this quantity may be
adjusted by moving the guide J¹ in or out directing the wire to the larger or
smaller part of the cone pulley, as may be desired to feed more or less at each
revolution thereof.
The lever D, which carries the wire cutter D2 has a forward extension D4
beneath which projects the inclined end of an arm L connected to a rock shaft L'
journaled in a bracket on the frame, the rear end of said shaft having an arm L²
adapted to be engaged by a cam L³ connected to the gear F3, the relation of the
latter to the die block actuating device being such that the wire will be severed
after the wire feed slide has completed the feeding movement.
The means for driving the machine and arresting the parts when desired, with
the dies separated, is shown particularly in Figures 3, 5, 8 and 10.
Mindicates a belt driving pulley secured to a sleeve M', supported in suitable
bearings M, and M³, a fly wheel on said sleeve.
N is a shaft within the sleeve, but normally unconnected therewith, its outer
end being supported in a bearing and having a pinion N2 thereon, meshing with
the gear and between the shaft and sleeve is a clutch device for connecting
them when desired. This clutch may be of any description, but preferably
consists of a disk 0 connected to the shaft by a screw and is provided with a
half round latch piece O fitting in a groove in the shaft and shaped so that
when turned to the position shown in Figure 2 the shaft and sleeve are uncon-
nected and it is provided with an arm 02 operated upon by a spring 03, the
tendency of which is to turn the latch so as to cause its edge to engage with a

page_text: notch O formed in the inner side of the sleeve and cause the shaft to be operated
thereby. Mounted upon the shaft F of the machine is a disk 05 having an
aperture 06 through which is adapted to be projected a bolt P mounted in a
socket in a stationary arm P¹ and having a pin Pa with which engages a lever P³
pivoted to an actuating rod P4 adapted to be secured by a pin P³ passing through
the table A¹
The driving sleeve or shaft is constantly rotated and when the machine is
not being operated, the bolt P projects through the aperture in the disk 05 and
engages the arm of the latch, holding the latter out of engagement.
In order to start the machine, it is only necessary to retract the bolt P from
the aperture in the disk and from beneath the latch-arm, and secure it by means
of the pin P5, which passes through the table and engages the rod P, and then
the spring 03 turning the latch will cause the engagement of the shaft and
sleeve. The disk, the bolt and the latch-arm are so relatively arranged as to
size and rotation that the bolt may be released when it is desired to stop the
machine and it will be pressed by its spring against the face of the disk and
when the aperture comes in line will pass through and engage the latch-arm,
thereby disengaging the clutch and automatically stopping the machine with
the die-carriers separated.
It will be understood that by reason of the fact that the dies operate on the
wire between them and move toward and laterally of each other, there is no
tendency to cause the displacement of the wire or to unduly crush or change
its shape other than to turn up the barbs properly and while the means shown
for causing the required movements of the dies is the best that my correspondent
is at present familiar with, he does not wish to be confined to this.
The wires barbed and cut by this machine may be sold to consumers who can
form the pipe cleaners by winding cotton or other similar material around the
barbed portion and remove it after use by burning it off, for instance, but the
wires for the cleaners are made by this machine cheaply and rapidly and are
adapted to be used but once and then thrown away.
Having now particularly described and ascertained the nature of the said in-
vention as communicated to me by my foreign correspondent and in what manner
the same is to be performed, I declare that what I claim is:-
