1. Improvements in Machines for Inserting Metallic Fastenings in
Boots and Shoes and Leather Work
(A cominunication from abroad by JAMES WILSON BROOKS of Petersham in the
State of Massachusetts, United States of America)
I ALFRED GEORGE BROOKES of 55 & 56 Chancery Lane in the County of London
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 ascertained
in and by the following statement:—
This invention has for its object to improve and simplify the construction of
that class of machines for uniting soles to uppers in which is employed a rotating
spindle containing a screw-threaded wire, which latter as it is rotated has its free
end screwed or forced into the material for a greater or less distance according to
the thickness of the material resting upon a suitable horn or work support.
The wire when inserted into the material for a distance equal to the length
of the fastening required at that point in the material, is cut off close to the
material, and, the latter having been fed over the work support, the end of the
wire is again inserted and again cut off to form a fastening, this operation
being continued.
In the inachine herein to be described, the threaded wire to be used is taken
from a reel having its axis of rotation substantially in line with the axis of rotation
of the spindle through which the screw threaded wire is passed on its way into the
material, and the spindle, fluted longitudinally at its outer side, is rotated at very
high speed.
The fluted part of the spindle engages and rotates with it an outer or feeding
sleeve provided with one or more gripper closing devices or surfaces herein shown
as anti-friction rolls, the said sleeve having openings at its side to receive friction
blocks, which latter are also extended through openings made in a sleeve-like
gripper-carrier, the slot in the outer sleeve being longer than in the gripper carrier
to enable the grippers to be relaxed from the wire.
The sleeve-like gripper-carrier has at its lower end and preferably pivoted
thereon, one or more grippers made in the form of levers which have their acting
ends or edges normally retained in suitable slots in a spindle-extension, the latter
having a central wire passage co-incident with the wire passage in the main part of
the spindle.
The gripper carrier derives its rotation from the outer sleeve acting on the
friction devices or blocks."
The inner sides of the friction devices referred to engage the periphery of the

page_text: spindle, thus connecting the gripper carrier frictionally therewith, but leaving the
gripper carrier capable of being moved upwardly longitudinally on the spindle
when acted upon by the lower ends of the slots in the outer or feeding sleeve
during its ascent, as when the grippers are to be released from the wire, there being
enough lost motion or play due to the excess of length in the slots of the feeding
sleeve, as compared with the length of said blocks, to enable the sleeve to be
moved for a slight distance upwardly from the lowest point of its stroke before
contacting with the friction blocks, to thus let the gripper closing surfaces retire
from the grippers in order that they may release the wire.
In practice, however, the upper ends of the slots in the friction sleeve, as long as
the wire is present in the spindle between the grippers, will not contact with the
friction blocks, for just prior to the arrival of the upper ends of the
slots of the sleeve in contact with the friction blocks, the gripper
closing surfaces of the outer or feeding sleeve act upon the inclined
upper ends of the grippers and cause them to grasp the wire firmly between
their lower ends, and thereafter during the further descent of the feeding
sleeve, it acting directly upon the grippers-, the said sleeve, solely by its pressure
against the grippers, maintains the engagement of the grippers with the wire,
keeping up this engagement until the end of the wire has been properly inserted
into the material.
In this manner all the force of the feeding sleeve in its downward movement may
be put directly upon the grippers, and through the grippers upon the wire.
The end of the wire having been inserted into the stock for a suitable length and
caught between the wire cutters, the outer or feeding sleeve is elevated, the
starting of the sleeve in its ascent immediately removing the gripper closing
surfaces from the grippers so that the latter are permitted to release the wire prior
to the rising or upward movement of the grippers outside the wire, the latter being
at such time prevented from retrograde or back movement by a suitable detent or
brake, herein represented as a roll having an annular groove, the bottom of which
is threaded or serrated to correspond substantially with the pitch of the thread of
the wire, the threads of the wire entering the serrations, a suitable pawl or
equivalent device preventing the rotation of the retaining device except in the
direction of the feed of the wire.
As the wire feeding grippers are mounted on the gripper-carrier and the latter
is held frictionally in contact with the rotating spindle, the said carrier does not
start to rise with the feeding sleeve until after the latter has been elevated
sufficiently or moved away from the grippers far enough to leave them free to turn
on their pivots and retire from the wire, but this done, the end of the slots in the
sleeve act on the friction blocks or devices and move the gripper carrier with the
sleeve during the remaining part of the upward stroke of the sleeve.
The friction blocks referred to are kept in place as against radial movement, and
the force with which the inner faces of the said blocks are made to engage the spindle
is determined or regulated by a regulating device shown as a ring having screw-
threads to engage threads at the outer sides of the blocks, the inner sides of the
blocks being faced preferably with or receiving a suitable friction surface preferably
leather or some equivalent material.
The regulating ring will preferably be made tapering at its inner side and be
sufficiently thin to yield somewhat so as to compensate for wear on the leather of
the several friction blocks and ensure uniformity of friction.
A friction device to co-operate with the spindle, the gripper-carrier, and sleeve,
as stated, during a part of each movement of the feeding sleeve, is an essential
feature of this invention, and it is not intended therefore to limit the invention to
the particular form of friction device shown.
The outer or friction sleeve is embraced by a reciprocating yoke.
The wire to be used in this machine will preferably be of the class containing a
double thread.
The spindle as herein shown is made in two. narts the lower nant
allad hanin

page_text: the spindle, extension being of sinaller diameter and inserted in an opening in the
main part of the spindle.
The extension is slotted to enable the wire feeding grippers to engage the wire
through the slots.
Preferably the extension will be fluted externally to engage flutes inside the main
body of the spindle, but the connection may be made in any suitable manner, the
provision of making the said slotted extension detachable resulting in great saving
in running the machine as it reduces the cost of repairs in case of wear of the
extension by the grippers and the wire.
In connection with the brake referred to it is preferred to use two pawls so con-
structed or mounted that when one is operated the other will remain substantially
midway the teeth of the ratchet, to thus ensure finer measurement in the fasten-
ings to be cut from the wire.
The wire passage outside the brake is acted upon by a guide, the chief function
of which is to keep the wire properly in the groove of the brake, the said guide,
shown as a movable block, having its acting face so shaped that it will properly
co-operate with the wire coming off the reel and into the spindle, notwithstanding
variations in diameter of the coil of the wire.
This brake will preferably be inade adjustable with relation to this guide, but
the converse would be within the scope of my invention.

A represents a suitable column upon which is mounted a head Ax having suit-
able bearings for the different working parts to be described.
The column has a sort of sleeve Bx, which receives the shank B of a suitable
horn or work support B.
The shank B has connected to its lower end a suitable rod B having an adjust-
able nut B, against the underside of which bears a spring B, the said spring being
seated on a suitable washer B, so that the spring normally acts to elevate the horn
and keep the leather or other material on it in contact with the fixed foot f which
rests against the upper side of the leather into which will be inserted the threaded
end of the wire to be thereafter cut off to forin a fastening.
The rod B² is connected to one end of a lever B³, see Fig. 2, the opposite end of
said lever having connected to it the rod BS in turn jointed in an adjustable manner
to a lever B³, see Figs. 1, 3 and 21, having its fulcruin at B; the shape of the said
lever being best shown in Figs. 3 and 21, the said lever having a U-shaped exten-
sion B** provided with a roller or other stud B which enters a groove B¹ in a
cam B shown separately in Fig. 22, and fast upon the cum shaft B.
The rotation of the cam B¹s through the devices described raises and lowers the
horn automatically twice during each rotation of the shaft, the horn being de-
pressed just before the feed is to take place, for herein it is desired to insert two
fastenings at each rotation of the cam-shaft.
The fulcrum B" for the lever B³ also sustains a horn lowering lever B the shape
of which is best shown in Fig. 2ª, said lever having a forward extension adapted to
receive upon it the foot of the operator, an arm B which is adapted to contact
with the underside of the lever B³ and a third arm having on it a weight B which
normally acts to keep the front of the lever B2 elevated, a projection B of the
lever by acting against a suitable stop determining the normal position of the
lever BS.
The shank B has extended from it an arın G, to the outer end of which is
joined a measuring rod G¹, the upper end of which enters a suitable guide G³ con-
nected to or forming part of the frame-work.
The upper end of the rod G' serves as a variable stop, against which may rest
the lower end of the measuring leg G³ jointed by a pin G to one arm of a three-
arined lever D" having its fulcrum at D¹³.
A collar 102 and spring 108 acting through a rod 100 resting on a lug 10, shown
by dotted lines Fig. 1, at the inner side of the lever 11 normally keeps the roll D16
carried by one arm of the lever D pressed toward the cam projections at the face
of the cam D, said can having two projections to vibrate the said lever twice
during each rotation of the cam shaft B upon which it is mounted.

page_text: The collar 102 is placed on the stud 103 and is clamped thereon between a
flange on the stud and a nut 110.
The stud 103 is fitted loosely into a bearing in the frame A* and a nut 110x pre-
vents the escape of the stud from the said bearing.
The collar 102 has a pin or projection 106 which is engaged by a notch 109.of
the spring 108 best shown in Fig. 11, the opposite end of said spring being engaged
by the fixed pin 107.
The cam D is shown best in Figs. 1 and 24.
The position to which the measuring rod G₁is elevated by the rising of the horn
in contact with the underside of the leather or other material,-the horn being
acted upon by the spring B-, will vary more or less according to the thickness of
the leather at the point where the screw threaded wire is to be inserted into it, and
consequently the upper end of the rod G' upon which the measuring leg G, rests,
by occupying different positions, will permit the roller D16 to enter more or less the
notches or spaces of the cam D, so that inore or less of the can grades of the said
cam will act to move the lever D¹14 more or less according to the thickness of the
leather, and consequently according to the length to which the wire is to be fed
for the fastening next to be cut off, the said lever D¼ being employed to actuate
the devices for that purpose, as will be described.
The cam B¹³ at its periphery has two toes C1, C2, which in the rotation of the
shaft come in succession against a projection 2 secured in an adjustable manner
by a suitable set screw 200, see Fig. 3, to one end of a lever C having its fulcrum
on the shaft B1, the opposite end of the said lever having as represented two arms,
one of which is kept against a suitable stop C17 by a spring 112, it acting upon a
rod 113, the rod entering a hole in the end of an adjusting screw 114; provided
with a check nut 115, by which to hold it in adjusted position, the upper end of
the screw acting against the said spring, the upper end of the spring in turn acting
upon a suitable collar on the rod, the adjustment of the stop C7 being such as to
keep the point of the projection 2 just in range with the toes C¹, C, but so as not
to touch the periphery of the said cam.
The coluinn A has erected upon it a stud screw H, upon which is placed a hub H¹
of a knee-lever H³, having at its inner end sector-teeth 20, which engage like
sector-teeth upon a block 21 secured to the lower end of a rock-shaft 22, having
bearings at 23, 24.
This rock-shaft has clamped to it a block 25, notched at its inner end to leave
two lugs which, as the rock-shaft 22 is turned by the knee-lever, may be made to
act upon a toe, 26, see Fig. 20, of a stop 27, pivoted at 28, and turn the said stop
about said pivot, thus putting it in position to stop the feeding operation for the
wire when desired, as will be described.
The measuring rod G³ has clamped upon it a foot 40, shown as a block having
a downward extension, which, when the stop 27 is in one position, is free to enter
the large hole in the said stop; but when said stop is turned to one side, as
described, by the knee-lever, then the said extension meets the top of the stop, and
so long as the said stop remains in such position the lever D" will not be moved
to feed the wire.
The stop referred to has co-operating with it a spring-controlled locking
device D, see Fig. 20, to hold it in either of its two positions where left by the
movement of the knee-lever.
One end of the lever C has connected to it by a stud C³ the upper end of a
link C, which at its lower end embraces a rod 116 mounted in one end of an
arm C, the hub of which is split as represented in Fig. 3, which split hub is
clamped by a clamping screw 117, shown by dotted lines in said figure, upon a
hollow rod or shaft C⁹.
This shaft C, inade hollow for sake of lightness, has,-
-see Fig. 7-, a double
segment Cox having two series. of. teeth 118 and 119, the teeth 119 being farthest
from the center of oscillation of the said shaft.
The teeth 118 engage teeth 120 of an arm 121, see Fig. 6, while the teeth 119

page_text: engage teeth 122 of an arın 123, see Fig. 5, said arms carrying the wire cutters 127
and 128.
The head of the machine has a bearing stud 124, see Fig. 1, the front end of
which is threaded as shown in Fig. 1, in order that it may be screwed into the
threaded hub 125 of the cutter arun 121, the said hub, projecting from the rear
side of the said arm and entering a hole 126 in the cutter arin 123, so that the said
arın 123 turns on the said hub.
The cutter arm 121 has a cutter 127, while the arm 123 has a cutter 128, each
being adjustably held in suitable grooves at the lower ends of the arins by suitable
clamping screws 129.
The arm 121 has a hole 130, shown by dotted lines Figs. 4 and 6, and the arm
123 has a like hole 131 in which is placed a suitable spiral spring 132 which is
acted upon by a screw 133 screwed into the arm 121, rotation of the screw increasing
or decreasing the effective strength of the spring, the spring normally acting to
separate the arms.
From the foregoing it will be understoad that whenever in the rotation of the
cams B¹³ the toes C, C, strike the projection 2, the lever C will be moved to
move the link C in the direction of the arrow next to it, and cause a partial oscil-
lation of the shaft C' and the segment Cox in a direction to cause the approach of
the arms and make the cutters enter and Sever the wire, this being done, however,
only after the end of the wire has been screwed into the stock.
It will be noticed that the teeth 120 and 122 are at different distances from the
centers of vibration of the arms 121 and 123, and to ensure equal movements of
the cutters so that each will cut uniformly from the outside to the center of the
wire, I have placed the teeth 119 farthest from the center of oscillation of the
shaft Co.
The head of the machine has suitable hearings D and 8 for the hollow
spindle A, through a central passage of which is led the screw threaded wire to
be inserted in the stock, said wire being taken from a spool a, see Fig. 15, mounted
upon a stud to be described, the said stud passing through a forked or bijurcated
portion a" of the spindle between which parts the spool is mounted so that the axis
of the spool is substantially in the line of the center of rotation of the shaft.
A suitable brake a" is employed to prevent any excess rotation of the spool by
or due to momentum when reeling the wire off the spool.
The upper end of the spindle above its bifurcated part a is extended through
the bearing D and has fast upon it a pulley Aª which is driven by a suitable
belt extended over idle pulleys A8 and thence down and over a pulley A loose on
a power shaft A3 provided with a suitable belt pulley A driven by a belt from any
suitable counter-shaft, the said pulleys in practice having each at their contiguous
sides, one a conical projection, and the other a conical cavity, to thus constitute
friction clutch pulleys, the loose pulley A being pushed in driving contact with the
face of the pulley A so as to cause it to be rotated therewith whenever the operator
puts his foot on the lever A' and elevates the wedge A so that its beveled ond acts
against the beveled end of a block A surrounding the shaft A³ between the said
rod A' and the hub of the loose pulley.
The bearing Ds has at its opposite sides guides De over which is fitted a yoke D¹º,
the lower end of which has a hole through which is extended the spindle A, the
edges of the opening of the yoke about the spindle being preferably provided with
small steel washers, see Fig. 15, to constitute tracks, against which may run suitable
anti-friction rolls or balls, one series of which is mounted in a friction box E and
the other in a cap plate c, one of the said series of rolls being marked C..
The cap plate c¹ is threaded and is screwed upon the upper threaded end of the
outer or feeding sleeve F shown separately in Fig. 3º.
This outer sleeve is slotted at its lower end at one or more places, as at b, into
which slots extend the upper ends of the wire feeding grippers b' to be described,
the said slots being intersected by pins 62, upon which as herein shown are inounted
: .

page_text: anti-friction rollers 63 which act upon and serve as closing devices or surfaces for
the said grippers, but if desired the rolls may be omitted.
This outer sleeve at a point above the rolls referred to is cut through at two or
more places leaving openings 64, the sleeve being herein represented as having three
such openings, see Figs. 3b, 3° and 17, each opening receiving a friction device which
in this present instance of this invention consists of a block b and a piece of leather
or other suitable material 6 at the inner side of the block, see Fig. 19", the said
leather acting against the outside of the spindle A.10.
Each block has at its outer side a series of projecting teeth 67 which are engaged
by the teeth of a regulating ring 6 surrounding the sleeve F, as best represented in
Fig. 15 and provided at its interior with a screw thread, the said regulating ring.
tapering internally so that by screwing the same down or up, the friction cf the
inner sides of the friction blocks upon the spindle may be increased or decreased,
the ring in practice being preferably sufficiently thin to enable it to yield somewhat
to compensate for wear on the leather of the several friction blocks, and to ensure
uniformity of friction.
The spindle A immediately below its lower bearing D is fluted longitudinally
as best shown in Fig. 16, and the inner side of the outer or feeding sleeve F is
correspondingly fluted to be engaged thereby, so that as the spindle rotates it will
rotate the said sleeve and yet perunit the sleeve to be reciprocated vertically upon
the spindle by or through the lever D₁ provided with rack teeth 5 which engage
suitable rack teeth upon the rear side of the yoke D1º, see Fig. 1.
Between the sleeve F and the spindle is a sleeve-like gripper-carrier d, shown
separately in Fig. 3, it having holes at corresponding in nuinber, and substan-
tially opposite the holes b in the sleeve F.
The friction blocks resting in the holes 6 of the sleeve F and also extending
through the holes d' in the gripper carrier, and toothed as stated, are slightly
tapered from bottom to top, being thicker at top.
The inner ends of the friction blocks in length are substantially of the length of
the holes d¹ in the gripper carrying sleeve, whereas the holes b* in the sleeve F are
slightly longer than the said blocks so that there is a small amount of lost motion
for a purpose to be described.
The sleeve-like gripper-carrier d, at its lower end has suitable studs d2 upon which
are mounted to turn, the wire feeding grippers 61 before referred to, shown as levers,
there being one or more such grippers, preferably three, as represented in Fig. 19,
the inner edges of the grippers near their lower ends being serrated and being
extended through slots d³, see Fig. 15, made in the spindle extension d screwed
into, as herein represented, the lower end of the main spindle A10, see Fig. 15.
The lower ends of the gripper levers remain constantly in the slots in the spindle
extension, and the upper ends of the grippers, as represented, are of cam shape or
beveled or inclined so as to be acted upon by the gripper closing surfaces of suitable
forin, carried by the feeding sleeve F.
When the feeding sleeve starts to descend, it will be remembered that the friction.
devices extend through the gripper carrier and engage frictionally the spindle, and
that the gripper carrier does not commence its descent with the feeding sleeve,
and as a result thereof, the feeding sleeve acts first upon the gripper levers causing
them to bite the wire firmly between their ends, and thereafter, during the further
descent of the feeding sleeve, the latter bears continually upon the grippers,
constantly holding their lower or wire gripping ends firmly against the wire, feeding
the saine out from the spindle and into the leather, the sleeve keeping up its contact
with the grippers, and never relaxing, but on the contrary, increasing their hold
according to the resistance to be overcome by the wire in entering the leather, until
the wire is fully inserted therein.
During the descent of the sleeve, after the grippers engage the wire, the gripper
carrier is forced down longitudinally over the spindle by or through pressure of the
sleeve on the grippers and the friction blocks b slide on the spindle A¹º
The wire having been screwed into the leather for a length suitable for a fastening

page_text: at that point, the cutters are operated to sever the wire close to the leather or to
the underside of the presser-foot of resting thereon, and thereafter, the yoke D1 is
elevated by or through the spring 108 acting on one arm of the lever D¹.
When the yoke starts to rise, the sleeve F rises with it, but the gripper carrier,
owing to the friction devices or clamping blocks carried by it and in engagement
with the spindle, does not rise with the sleeve at first, and consequently the lower
end of the sleeve retires from the grippers, permitting them to release the wire,
and, owing to the rapid rotation of the spindle, the grippers, due to centrifugal
action, are taken from engagement with the threads of the wire, and thereafter,
during the continued rise of the yoke and the sleeve F, the gripper carrying sleeve
is lifted by or through the action of the lower ends of the slots 6' of the said
sleeve F against the friction blocks, the latter at such time sliding upwardly upon
the spindle, the extent to which the gripper carrier is lifted depending upon the
thickness of the leather, as stated.
The rapidly rotating spindle has a worm d', the teeth of which engage worm
gears d', d, having teeth of suitable pitch to operate properly with the pitch of the
threads of the wire being used.
The worm gear d' is fast on an auxiliary shaft d* having at its rear end, see
Fig. 1, a toothed gear d" which engages a toothed pinion represented in Fig. 3
adjustably fixed to one side of the cam hub B's fast on the shaft B14.
The worm gear d' is fast on the front end of the shaft B carrying the cams
referred to for actuating the different parts of the machine.
By the employment of the auxiliary shaft dx I am enabled not only to equalize
the strain upon the spindle by supporting it at each side its center of rotation, but
I am also enabled to more accurately and powerfully drive the shaft B.
The inner side of the cam D has a groove DITX, see Fig. 23, into which enters a
roller or other stud e, represented by dotted lines in Fig. 3, at the upper end of
a lever e' pivoted at 2 upon a suitable stud in the frame-work, the lower end of the
said lever being grooved or slotted as at e³ to receive a swivel block mounted
upon a pine made adjustable in a slot at the upper end of a lever pivoted at e',
see Figs. 1 and 3, and having at its lower end a segmental rack 30 which engages
the teeth m of a long hub having an attached pawl-carrier m" provided with a
pawl m which engages teeth 30 of a ratchet fast upon a shaft ms having
its outer end beveled and provided with teeth to engage bevel teeth at the under-
side of a wheel m', see Fig. 12, which is adapted to be rotated about a suitable
stud 44, the wheel being kept on the stud by a suitable screw 45 and a washer 46.
The shaft m³ is extended through a sleeve m* firmly clamped in place in the
frame-work.
The shaft m³ is surrounded between the box m' and the ratchet m with a
raw-hide or other washer 161, and at its rear end within the sleeve 162, I have
placed a washer 163 made adjustable by means of a screw 164, the rotation of the
said screw enabling any wear upon the said washers to be compensated for, to thus
always prevent any backward rotation of the shaft m³ when the pawl carrier is
reversed or going through its inoperative stroke.
These washers also prevent any overrunning of motion.
The box 162 is acted upon by a spring 165, in turn made adjustable as to its
effective strength by a suitable screw 166.
The employment of the washer 163 made adjustable by the screw 164 as to its
position in the box 162, precludes the contact of the end of the box with the pawl
carrier during its movement, so that the pawl carrier have an absolutely free
movement.
The box msee Fig. 12, is herein represented as provided at its upper side with
rack teeth which are engaged by pinion-like teeth cut on a bolt 170, mounted in a
part of the head and having, as shown, a crank handle 171.
By turning this shaft the box referred to inay be adjusted longitudinally
toward and from the position occupied by the lower end or nose of the spindle
according to the distance it is desired to insert the fastenings from the edge of the

page_text: •
sole, and during this operation, the feeding wheel or device m' will be moved with
the box.
The periphery of the wheel m¹ is toothed to engage the edge of the sole or
leather upon the horn and feed the same the proper distance between one and the
next fastening, the adjustment of the stud es on the lever e" and in the slot e³ of
the lever providing for variations in the length of feed of the stock.
The head of the machine has suitable serrations g, see Fig. 1, which are engaged
and embraced by serrations of a jaw at the inner end of the presser-foot f, a
clamping screw 2 causing the end of the foot to be clamped firmly upon the head,
the grooves preventing any possibility of the foot being turned out of proper
horizontal position, and affording means for adjusting the foot vertically.
The front end of the foot may desired have a slot as at through which may
extend the pointed lower end or nose o' of the slotted spindle extension.
In the machine herein described the cams upon the cam shaft each have a
double throw, so that they operate twice, during each rotation of the said shaft,
the devices to be actuated by them, as for instance, the wire feeding mechanism,
the wire cutting mechanism, and the shoe feeding mechanism, whereas in former
machines, it has been customary to have the said cams actuate the said devices
but once during the rotation of the cam shaft.
or
The wire carrying spool is mounted on a pin 21, the point end of which is
heavier than the head end, or in other words, the said pin is bored out
chambered at its head end, see Fig. 14, and such a pin, in view of its point
being heavier and because of the rapid rotation of the spindle, will always reinain
in place to properly support the spool.
The point of this pin is tapered so that it may be quickly and easily inserted to
contine the spool in place, which is not the case with a bolt of uniform diameter
and having a threaded end.
The stud D15 on which turns the lever D" instrumental in feeding the wire, is
also of peculiar construction, as shown in Fig. 13.
The stud is bored and threaded centrally from one end, as represented in
said figure, to receive a pointed screw t, and the stud is slotted longitudinally
at two or more places so that the said screw may act as an expanding device
when screwed into the stud and expanding the same within the bearing in the
head A*.
The serrations at the lower ends of the wire feeding grippers which directly
engage the wire, are and preferably will be cut or formed thereon at an inclination
different from that of the pitch of the thread of the wire directly in contact with
the gripper, such manner of teeth affording a better hold of the gripper on the
wire in the screwing of the wire into the leather.
Each cutter carrier 121, 123, as herein shown, is provided with a guard as 160,
the same being attached to the carrier in suitable manner, herein represented by a
screw 161.
These guards cross or overlap one the other, both when the carriers are closed
and when they are open, and thus prevent the possibility of chips getting between
the teeth of the segment and the rack teeth of the carriers.
The spindle A just below the spool has a brake shown as a wheel or roll n
mounted on a stud n¹ in a plate n², through slots in which are extended clamping
screws n³, the said plate being made adjustable longitudinally by an adjusting
screw n' toward and from the guide n³ forked or bifurcated to embrace and keep
the wire in the groove of the brake, the bottom of said groove being notched or
threaded to engage the wire.
The brake roll is provided with ratchet teeth at one cr both sides of its groove
to be engaged by one or two detents nº, n', one being preferably a little longer than
the other, as by two detents more accurate measurements or motions may be
5 controlled as will be understood by mechanics.
A suitable spring ns serves to keep the acting ends of the detents in engagement
with the ratchet teeth of the brake.

page_text: From the foregoing description, it will be understood that the cutting mechanism
cuts the wire at a point just below the end of the spindle and just below where
the wire feeding grippers grasp the wire to feed it, and that the brake which
prevents the retrograde motion of the wire when not grasped by the wire feeding
grippers, is located quite near the reel of wire.
This feature of applying the brake for the wire at a distance from the cutter,-
the brake holding the wire while the cutter is acting and while the wire feeding
grippers have retired from the wire,-is a matter of very considerable importance,
for the reason that the wire being acted upon by the cutters, although being
rotated at a very high speed, has an opportunity to twist a little during the cutting
operation between the point where the cutters engage the wire and the brake, and
as a result thereof, the cutters are enabled to effect a chisel pointed cut, leaving a
chisel point on the extremity of the wire, which greatly assists its entrance into
the stock.
The ring 6 surrounding the feeding sleeve loosely is free to move outside the
said sleeve and without contact therewith.
This sleeve also wholly supports the friction devices or blocks, and is in turn sup-
ported by the teeth on the outer sides of the said friction devices or blocks
engaging the threads at the inner side of the ring.
The tapering inner side of the ring & co-operating with the reversely tapering
blocks enables the ring to support the blocks from falling.
Referring to Fig. 3, it will be seen that the gear is attached to the cam B¹³ by
a series of set screws extended through slots in the gear d', such slots
providing for adjustment of the gear with relation to the toes of the cam B¹³, as is
necessary to compensate for wear and to ensure correct timing of the action of the
cutters with relation to the wire feeding mechanism.
In the modifications Figs. 25 to 29 inclusive, the spindle A" is fluted internally
as at 12, Fig. 28, to receive external flutes on the spindle extension d*.
The spindle A is surrounded by a gripper carrier 7 shown as a cylinder-like
casting fluted internally as best shown in Fig. 29, to engage external flutes on
spindle A, so that the spindle in its rotation effects the rotation of the gripper
carrier with it.
The gripper carrier has ears 55 to receive pins 66 on which are pivoted the lever-
like grippers 10 having shoulders n2 to be acted upon by the outer sleeve o to
close the grippers on the wire at the center of the spindle.
The gripper carrier has openings 77, lugs 10, and a grooved block
Friction devices shown as blocks and having a friction surface as " and a
finger are joined in like manner to the gripper carrier by suitable screws 7, the
friction blocks bearing against a smooth part of the spindle A while the finger 7.º
enters a groove in the block 7.
The friction device rises and falls in unison with the gripper carrier r, the
block sliding on the spindle frictionally as the said carrier is moved vertically
by the outer sleeve o connected with the yoke D before described, the sleeve o
having sufficient lost motion, shown at 10, Fig. 28, to enable the lower end of the
said sleeve to act on the shoulders and close the grippers on and to feed the
wire, or to enable the grippers to release the wire.
The wire brake in the spindle is herein shown as composed of two tapering
blocks p between which the wire is passed the upper conical end of the brake
being normally pressed into a conical seat in the spindle A, such action closing
the clamp on and preventing back notion of the wire, the spring yielding when
the wire is going into the boot or shoe.
The gripper levers in this modification of my invention are acted upon near
their lower ends to close thein on the wire, but in Figs. 1 and 3*, the gripper levers
are acted upon at their upper ends.
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:
