WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN LACING STUDS CHIEFLY
DESIGNED FOR BOOTS AND SHOES, AND IN MACHINERY FOR MANUFACTURING
AND SETTING THE SAME." A communication from abroad by Mellen Bray, of
Newton, Massachusetts, United States of America, Manufacturer.
The first part of this Invention relates to that class of lacing studs described in
the Specification of Letters Patent, dated 9th day of June, A.D. 1877, No. 2253,
and especially to an improvement in the construction of the tubular or hollow
shanks of such studs, whereby the shank is better adapted than heretofore to resist
the pressure applied thereto to force it through the material and cut its own way,
and it consists in forming the said tubular shank with its walls of varying thickness,
that is to say, gradually increasing in thickness from a point near its cutting edge
to the under side of its head, with a chamber within the said shank of uniform
diameter throughout, or slightly smaller at its inner end than at its outer end, so
that the wall of the shank shall present the greatest possible resistance to the
pressure exerted to force it through the material with the least amount of metal,
thereby enabling it to cut its own way through the material without crippling or
distortion.
The object of this part of the said Invention is to overcome a difficulty in setting
tubular studs, which consists in the crippling of the shank just under the head,
occasioned by the resistance presented to the passage of the shank through the
material in cutting its own way. This difficulty has been a source of considerable
trouble especially if the stud is made of brass, and is made to cut its own way
through the material as is now almost universally the case; but by increasing the
thickness of the walls of the tubular shank toward the head I entirely obviate this
difficulty, and this increase of thickness may be obtained by making the exterior

page_text: of the shank of uniform diameter throughout, and drilling out its centre with a
tapering drill so as to form therein a chamber extending from its end to the under
side of the head and gradually diminishing in diameter toward the head; or the
rivet may be formed with an exteriorly tapering shank, and have formed therein
a chamber of uniform diameter extending to the under side of the head.
Another advantage of this improvement is that-the shank clinches better, turning
over on the material with a inore even and true curve, and is less liable to split,
thereby-making smoother work than has been heretofore practicable.
-In-the-accompanying Drawings,—
be formed.
Figure B is a side elevation of the completed stud.
Figure C is a plan of the same drawn to an enlarged scale.
Figure D is a central vertical section on the line x, x, Figure C illustrating one
form of constructing the tubular shank, and
Figure E is a similar section illustrating a modification of the said tubular
shank.
a is the tubular shank of the studs; is the head proper which bears upon and
clamps the leather or other material when the stud is set therein; and c is the
secondary head which, with the excentric neck d, forms the hook of the shoe stud,
as shewn in Figures B, D, and E, which hook is designed to receive a lacing cord,
substantially as and for the purposes described in the Specification of the said
former Letters Patent.
The shank a is made tubular from its end to the under side of the head b, the
- walls of said tube being made thicker just under the head than at its point, and
the chamber formed within said shank being made uniform in diameter throughout,
as shewn in Figure E, or slightly smaller at its inner end than at its outer end, as
shown in Figure D.
This stud may be made by first forming a solid shank of uniform diameter
throughout, and then drilling out the centre of the said shank with a taper drill
so as to forin therein a chamber of varying diameter, as shown in Figure D; or the
stud may be formed with its shank taper exeriorly from the under side of the head
b toward the point, and then drilling out its centre so as to form therein a chamber
of uniform diameter, as shewn in Figure E.
The second part of this Invention relates to inachinery for completing the manu-
facture of the lace stud after the blank shewn in Figure A has been formed by a
previous operation, and especially to the means employed to separate the blanks,
feed them to the operating tools, hold them in position while being acted upon,
thereby drilling out the shank to form a hollow tube, cutting a groove in the head
to form an excentric neck to receive the lacing, and shaping the outer collar of
the hook head of the stud, and it consists partly in the use of two or more pairs of
clamping jaws mounted upon a disc or spider at equal distance from each other, and
from the axis of said disc or spider in combination with two or more levers pivotted
-to-said-disc-or-spider, each connected at one end to the movable portion of one of
the clamping jaws and adapted to be vibrated about its pivot in a plane radial to the.
axis of the disc or spider, and move said movable portion of the jaws radially in its
bearings in said disc to clamp or unclamp the shank of a stud blank placed between
said jaws, said levers being each connected at its other end with a toggle joint or
other suitable device for forcing said lever end toward the axis of the disc and
locking it in such position while the disc and levers are together intermittently
rotated about a common axis.
This Invention further consists in the use in combination with the intermittently
rotating clamp-carrying disc or spider, of locking devices adapted to lock the said disc
and hold it in a fixed position while the drill and the nicking tool are operating
upon the blank to form a finished stud.
It further consists in the use in combination with the intermittently rotating and
clamp-carrying disc or spider of a registering device adapted to correct any imperfec-

page_text: tion in the intermittent rotary motion of said disc, and bring the blank held by the
clamping jaws into a true axial line with the drill.
It further consists in the combination of an intermittently rotating and clamp-
carrying disc or spider adapted to receive clamp and hold the blanks in a fixed posi-
tion therein, and convey them in succession to the different points of operation, a drill
arranged upon one side of the said disc, and adapted to be rotated at a high rate of
speed about an axis perpendicular to the plane of revolution of said disc and to be
moved end wise toward said disc for the purpose of drilling out the shank of a stud
blank held in the clamping jaws; and a cutting tool arranged upon the opposite
side of said disc, and adapted to form an excentric neck in the head of a stud at the
same time that a shank is being drilled.
It further consists in the combination of an intermittently rotating disc or spider,
having mounted thereon and rotating therewith two or more pairs of automatically
operated clamping jaws or dies, an automatically operated drill, and a discharge
plunger, arranged upon one side of said dise and adapted to operate upon different
studs at the same time, and a rotating cutting tool arranged upon the opposite side
of said disc and adapted to form an excentric neck in the head of a stud blank while
a shank is being drilled.
It further consists in the combination of an intermittently rotating disc or spider
having nounted thereon and rotating therewith, two or more pairs of automatically
operated clamping jaws or dies, an automatically operated drill, and a discharge
plunger arranged upon one side of the disc and adapted to operate upon different
studs at the same time, and two revolving cutting tools arranged upon the opposite
side of said disc and adapted to operate upon two different studs at the same time,
one to form the eccentric neck in one stud and the other to finish and shape the
outer convex surface of the hook head of another stud.
It further consists in the combination of a disc or spider mounted upon one end
of a shaft, and having mounted in suitable bearings thereon two or more pairs of
clamping jaws or dies, two or more levers pivotted to said disc or spider, and each
connected at one end to the movable portion of one of said clamping jaws, and at
the other end to a toggle joint; a second spider or skeleton frame mounted upon
the opposite end of said disc shaft, and forming bearing supports for the fulcrum
pins of the several levers operating toggles, all adapted to be intermittently rotated
about a common axis to carry a blank held by either pair of clamping jaws from the
point where it is received successively to a position in line with the several oper-
ating tools, a reciprocating plunger in a position and adapted to act upon a toggle to
straighten it, and thereby cause the movable jaw to close upon and clamp the blank
immediately after said blank is fed between said movable jaw and the fixed jaw,
and a vibrating lever in a position and adapted to act upon another toggle to break
or bend it from a straight line to release the pressure of the clamping jaws upon the
finished stud preparatory to its being discharged from the machine.
It further consists in the combination with an intermittently rotating disc or
spider, having mounted thereon a series of clamping jaws or dies adapted to receive
a blank to be automatically closed upon, and hold it firmly during the several
operations of drilling the shank, and then unclamp the finished stud to allow it to
be discharged; of a device for separating a single blank from others in bulk and
feeding it between a pair of jaws; two rotary cutters for finishing the heads of the
studs, all arranged upon one side of the disc, and each opposite a different pair of
jaws when said disc is in a state of rest, and an automatically operated drill and a
discharge plunger arranged upon the opposite side of said disc, and adapted to be
moved end wise toward and from said disc in paths perpendicular to the plane of
revolution of said disc, and to act upon different studs or blanks at the same
time.
It further consists in the combination with an intermittently rotating and clamp-
carrying disc or spider of a pressure brake applied thereto to prevent said disc
from being carried too far around its axis at each intermittent movement.
It further consists in a peculiar arrangement and combination of devices for

page_text: separating a single blank from a number placed in a hopper in bulk and feeding it
into a position to be seized and held by its shank between a pair of clamping jaws,
the novel features of which will be best understood by reference to the description
of the Drawings.
It further consists in-the-use-of_an_annular or ring cutter, having its cutting
knives or teeth upon its inner edge, and adapted to be moved over the head of the
-blank.in-a-line parallel with its axis of revolution and concentric or nearly-con-
centric-with the axis of the stud, and-then to be moved laterally or at right angles
to its axis of revolution while revolving at a high rate of speed, thereby cutting
a groove-into-the-head of the blank in such a manner as to partially divide said
head into two collars connected together by a neck located excentrically thereto, as
☐ will be described.
It further consists in the combination of a cutter-carrying spindle adapted to be
revolved at a high rate of speed about its axis, and to be moved endwise, and an
excentric sleeve surrounding and forming the bearing for said spindle, and mounted
in a suitable bearing or bearings, and adapted to be intermittently rotated within
said bearing to feed the cutter to its work, by causing the axis of the cutter spindle
to move through a small circle excentric to the axis of the blank, being acted upon
by the cutter, thus forming a circular neck upon the stud located excentrically to
its shank and the two collars of its head.
It further consists in the combination of a cutter headstock provided with
movable boxes carrying a cutter spindle adapted to revolve therein at a high rate
of speed, and an adjusting wedge operated by a screw to accurately adjust the cutter
to the work to be done.
It further consists in the combination of a cutter headstock, a cutter-carrying
spindle having its bearing in an excentric sleeve adapted to be intermittently
revolved within its bearing in said cutter headstock, and all adapted to be inter-
mittently reciprocated in a direction parallel with the axis of the cutter spindle,
and a locking device for holding said cutter headstock in a fixed position while the
cutter is forming the neck of a stud.
It further consists in the use of an annular cutter for cutting the groove to form
the excentric neck, composed of a chisel-shaped tool, fitted to a dovetailed groove in
the side of a ring holder cut open upon one side in the rear of the tool, and adapted to
clamp and hold said tool in position by the spring of the holder in combination with a
furcated chuck or socket adapted to clamp said ring holder and spring it on to the chisel-
pointed tool, the cutting point of the tool being toward the centre of the ring holder.
It further consists in the combination of a cutter-carrying spindle adapted to be
continuously revolved about its axis at a high rate of speed; an excentric sleeve
surrounding and forming a bearing for said spindle mounted in a bearing or bearings.
encompassing its periphery, and adapted to be intermittently rotated therein at
regular and equal intervals of time, with a period of rest after each complete revo-
lution; and a locking device adapted to prevent said excentric sleeve from being
accidentally moved about its axis during its period of rest.
It further consists in the combination of an intermittently rotating disc or spider,
having mounted thereon and moving therewith two or more-pairs of automatically
operated clamping jaws or dies; a rotating cutter adapted to be moved toward and
from the face of said disc in a liue perpendicular to the plane of motion of said disc,
with its axis in line with the centre of the opening between a pair of said clamping
jaws when the disc is in a state of rest, a cam lever and connecting rod for im-
parting such reciprocating motion to the cutter, and a spring arranged to resist by
its tension the movement of said cutter toward the disc and prevent a sudden
jumping forward of the cutter, which it would otherwise be liable to do, to the
injury of the stud head.

A is the bed frame supported upon the legs B, and having mounted in suitable
bearings therein the cam shaft C, drill spindle D, disc shaft E, gear shaft F, dis-
charge bar or rod G, and registering rod H, all arranged as shown, and operated as
will be herein-after described.
The drill spindle D is provided with the two tight pulleys D1 and D2 and the
loose pulley D³, and is revolved at a high rate of speed by means of a belt (not
shewn) leading from an overhead countershaft (also not shown) on to the pulley D',
which belt may be shipped on to the loose pulley Ds by the shipper fork a, shipper
rod a', and spring a when it is desired to stop the machine, the said drill spindle.
being moved endwise to feed the drill to its work by the cam C.
I is a shaft mounted in bearings on the cross ties of the legs B, and having
secured thereon the pulleys I', 12, 13, and has a rotary motion imparted thereto by
means of the belt 1 leading from the pulley D² on the drill spindle to and around
the pulley I.
A belt J leading from the pulley I to and around the pulley J on the shaft J,
imparts thereto a rotary motion about its axis, said shaft being mounted in bearings
in the upper ends of the stands K and K' bolted to the sides of the frame A, and
has mounted thereon the worins J3 and J and the cam J.
The worm J³ engages with the worm wheel C¹ on the cam shaft C, and by its

page_text: action thereon imparts a slow rotary motion to said shaft, and the cams C2, C3, C4,
C, C, C7, and Cs, all secured firmly thereto in their proper relative positions.
The shaft E has firmly secured thereto near its front end the disc E', to the back
side of which are pivotted-the-four levers E, the long arm of each of which extends
Ebackward therefrom parallel or nearly so to said shaft, and has-pivotted-thereto the
adjusting saddle E3, to which is pivotted the inner end of the toggle E, the outer
-end of which is pivotted to the spider E5, secured firmly to the shaft E.
A ratchet wheel b is firmly secured to the shaft E at its rear end, with which the
pawlbhung upon the lever 62 engages, said lever b being mounted loosely upon
the shaft E, and connected at its other end by-means of the connecting rod b³ and
--ball-and-socket joints, with the movable end of the lever b pivotted at its opposite
end to the stand 65, and provided with a truck which fits into and is acted upon by
the path b in the cam C, adapted to impart an intermittent rotary motion to the
disc E' at regular and equal intervals of time, said disc moving through an arc of
ninety degrees at each intermittent movement.
:
The forward end of each of the levers E2 is forked and engages with a lug
projecting from the rear side of the moveable jaw or die c fitted to a dovetailed
bearing in the front face of the disc E' in such a manner that it may be moved
radially in said bearing, said jaw or die being made of a thickness about equal to
the length of the shank of the stud blank to be operated upon, and has formed
across said outer end a semi-cylindrical groove adapted to fit said shank and clamp,
and hold it in conjunction with the fixed or stationary jaw or die c¹ provided upon
its inner end with a corresponding semicircular groove.
Just outside of the fixed die c¹ is set in the periphery of the disc the hardened
steel plate d, in the edge of which is formed a V shaped detent notch with which
the levelled or tapering forward end of the registering rod H fits to correct any
inequality in the movement of the disc, and bring it into accurate position relative
to the drill and cutting tools.
.
A radial hole is also formed in each of the plates d, the purpose of which will
herein-after appear.
The worm J engages with and causes to rotate the worm wheel F" firmly secured
upon the outer end of the shaft F, mounted in a single bearing A¹ in the front end
of the frame A, and having secured upon its inner end the bevel gear wheel F2 and
cam F3
Secured to the inner side of the worm wheel F' is a path cam F, the path of
which engages
with. a truck e¹ mounted upon a pin projecting from the perpendicular
bar e,
and imparts to said bar a vertical reciprocating motion in the bearing formed
for the purpose in the stamp e projecting upward from the cap of the bearing A',
the upper end of said bar e being connected by means of the link e³ with the
movable end of the lever f¹ secured upon the end of the shaft f having its bearings
in a side branch of the stand K', and having firmly secured thereon the hopper g,
all so arranged that the vertical reciprocation of the bar e shall cause the hopper g
to be vibrated about the axis-of-the-shaft f, so as to be inclined in opposite directions
at the two extremes of its movement for the purpose of agitating the blanks placed.
therein, and cause them to drop into the slot g¹ formed in the centre of its bottom,
and be delivered therefrom into the inclined chute h, down the spiral goove of
which they slide till they reach the vertical groove h¹, into which they drop one
above the other.
The spiral groove of the inclined chute is partially covered by the plate ², and
the hopper g is provided with two projecting guide fingers g² arranged one upon
either side of the groove gl, and curved concentric with the axis, about which said
hopper vibrates the under sides of the blanks resting upon said fingers as they slide
from the hopper to the inclined chute.
The hopper g is also provided with a light flat spring g³ projecting therefrom over
the fingers g in a position to bear lightly upon the heads of the blanks, as they
pass from the hopper to the chute and serve in connection with said fingers to carry
back-any blanks that may remain above the end of the chute when the hopper is

page_text: vibrated away from the chute, and thus prevent them from being accidentally
thrown out of the chute or guideway into or among the machinery.
The lower blank in the vertical groove or guideway h¹ is pushed out from under
those above it by the spring-actuated plunger i, and carried along the horizontal
guideway and deposited in the horizontal guideway extending across the end
of the guideway ¹, and at right angles thereto with its axis parallel with the axis
of the disc, and with its smaller or shank end towards the disc in a position to be
moved endwise along the guideway 2 by the reciprocating plunger till the shank
of the blank enters between the clamping dies c and c' with the shoulder of its head
bearing against the outer face of said dies.
The feed plunger has an intermittent reciprocating motion imparted thereto by
the cam F and the elbow lever F5, the vertical arm of which is a steel spring, and
is connected by the link to the plunger j, as shown, the object of the spring
lever F5 being to prevent damage to the mechanism in case a blank should become
obstructed in any way in the guideway 2, so that it could not be moved into position
between the clamping dies.
The inner end of the spring-operated plunger i is made to conform to the shape
of the side of the stud blank both longitudinally and circumferentially, as shewn in
Figures 14 and 15, whereby the blank, shown in Figure 15, is held in a hori-
zontal position, or with its axis coinciding with the axis of the guideway 22 and the
feed plunger j, a spring actuated pin 3 located directly opposite the plunger i, and
having its inner end bevelled, as shown in Figure 15, aiding in so holding the
blank and serving to prevent the blank from being canted to one side when it is
first served forward by the plunger by presenting about an equal resistance to
such forward motion upon two opposite sides of the blanks.
An elbow lever, pivotted at 1, is connected at one end to the plunger i, and is
acted upon at its other end by the push-finger 13, secured to the upper side of the
block m loosely mounted upon the plunger j, and connected therewith by the
pin m projecting from the side of the plunger j through the slot m² in said block
in such a manner that the plunger ; may be moved through said block during a
portion of its movement, and then cause said block to move therewith.
The inner end of the guideway 2 is provided with a contracted mouth of a
diameter corresponding to the diameter of the shank of the blank, said mouth being
composed of two jaws n, n, connected by the plates n¹, n', to the block m by means
of the screw pins n², n² passing freely through slots o, o, formed in said plates,
said jaws being forced together by the springs o¹, o¹, all as shown in Figure 16.
The bed or frame, in which are formed the guideways h¹, i', and i, is composed of
three pieces p, p, and p³, secured together by screws or rivets for convenience in
constructing the several guideways, the whole being supported upon and secured
to the arched stand L bolted to the cross tie A2 of the frame A.
M is a cutter headstock having mounted in suitable boxes M', M', adapted to be
adjusted by the wedge 9 and screw q¹, a sleever, the inner bore of which is
excentric to its outer periphery, and having formed upon one end thereof, outside
of its bearing, the spur gear wheel and hub 2, one side of which hub is made
concave, as shewn in dotted lines in Figure 8.
A gear wheel N, having cogs or teeth on only about two-thirds of its periphery,
is mounted by its hub in a bearing in the tie girt A2, said hub surrounding and
forming a bearing for the forward end of the disc shaft D, which revolves freely
therein.
To the front face of the wheel N is secured the level wheel N', which engages
with and is rotated by the level gear wheel F2.
To the rear side of the gear wheel N, opposite that portion of its periphery
where there are no teeth, is secured the segmental plate N, the outer edge of
which engages with the concave side of the hub 2, and effectually locks the sleeve r
and prevents it from being accidentally revolved during the time that the cutter is
being moved toward or from the disc.
A tubular spindle is fitted to the bore of the excentric sleeve with a conical

page_text: bearing therein at its inner end, and having secured to its other end the pulley O,
also having a conical bearing against the excentric sleeve 7, and adapted to be
adjusted upon said tubular spindle to take up the wear.
To the inner end of the tubular spindle is fitted the furcated chuck head,
having a taper bearing therein, and-connected_to_the spindle so as to be compelled
to revolve therewith-by a longitudinal slot formed in its shank, and a pin passing-
through-said tubular spindle into said slot.
The-chuck head is drawn into the conical mouth of the tubular spindle 3 by
means of the hand wheel o" and its tubular shank, the inner end of which screws
on-to-the-end-of-the-shank of the chuck head, as clearly shown in Figure 4.
The cutter headstock is fitted to and mounted upon a dovetailed slide formed
upon an extension of the left-hand side bar of the frame, along which it may be
moved toward or from the disc by means of the rod P, attached by one end to said
headstock, and having its other end acted upon by the path cam C2 to impart
thereto a short reciprocating motion, said rod being guided by the bearing P', as
shewn in Figure 2.
To ensure perfect and uniform work in cutting the neck of the stud it is
important that the disc should be locked to prevent the slightest circumferential or
other movement during the time the neck is being formed, and also that the cutter
headstock should be held firmly in a fixed position while the cutter is operating
upon the stud to form the neck. This is accomplished in the following
manner:―
The disc is first brought into position with the axis of the blank held between
the clamping jaws in line with the axis of the drill by means of the registering bar
or rod H, to which an intermittent reciprocating motion is imparted by the cam C³,
and then the disc E' is locked by the bolt being forced radially into the hole in
the plate d by the inclined slot s' in the arm P2 secured upon and moving with
the rod P acting upon the pin s projecting upward from the bolt s, as shewn in
Figure 11.
When the cutter headstock M has completed its motion toward the disc and
before the eccentric sleeve 7 commences to rotate to move the cutter into contact
with the stud for the purpose of cutting the neck, the cam C³ acting upon the lever
P3 causes the tapering lower end of the registering and locking bolt P to be forced
into a detent notch having tapering sides forined in the upper edge of the rod P, as
shewn in dotted lines in Figure 2, thus correcting any irregularities in the forward
movement of the cutter headstock caused by wear of the parts or otherwise, and
firmly locking the same in position.
The cutter headstock may be adjusted nearer to or farther from the disc by means
of the coupling P5 connecting the two parts of the rod P by means of right and
left hand screw threads.
The end of the chuck head has formed therein a recess, the walls of which are
slightly undercut to receive and close upon the dovetailed hub t¹ of the tool-holding
ring-t.in which is set the cutter & fitted to a dovetailed groove in the side thereof,
said ring being cut apart in the rear of said cutter and cut nearly apart upon the
opposite side thereof by the slit 3, as shown in Figures 22 and 23 drawn full
SIZC.
The clamping of the chuck head upon the ring holder t causes said ring to be
nipped upon the cutter and hold it firmly in position.
The cutter spindle and eccentric sleeve are so arranged and adjusted that when
the eccentric sleeve is at rest the axis of the cutter spindle shall coincide or nearly
coincide with the axis of the stud blank clamped in the disc and with the axis of
the drill with the cuttter at such a distance from the centre of said spindle that
the headstock may be fed towards the disc with the cutter revolving about the head
of the blank without touching said head.
Rotary motion is imparted to the cutter spindle by means of the belt Q leading
from the pulley Is to and around the pulley O.

page_text: Friction is applied to the periphery of the disc to prevent too great a movement
around its axis by the spring-pressed brake u as shewn in Figure 10.
The discharge bar or rod G carries at its rear end a truck with which the
path of the cam C7 engages and imparts to said rod an intermittent endwise
motion.
An upwardly projecting lug G¹ is formed on the rear end of the bar G and
engages with the adjustable bolt head u set in the lever G, causing the movable
end of said lever, together with the plunger 3 connected thereto, to be moved
toward the disc to straighten the toggle E which at the time is directly over the
shaft E, thereby depressing the rear end of a lever E2 and causing the clamping.
jaw c to close upon and clamp a blank just fed between it and the jaw c¹.
The bar G also has mounted upon a suitable stud set in its under side a truck v
which fits into the curved path v formed in the upper side of the curved lever R
pivotted at 2 to a stand or ear projecting inward from the frame A, all so arranged
that a movement of the bar G toward the disc will cause the lever R to vibrate
about its fulcrum and its free end to strike and break or throw out of a straight
line one of the toggles E' and remove the pressure of the clamping jaws from the
finished stud when in a position to be discharged.
The front end of the bar G has set therein a steel discharge plunger, which
engages with the tubular end of the stud and forces it out of the disc when the bar
G is moved forward.
S is a curved arm secured upon the bar G and moving therewith; to the lower
end of this curved arm is pivotted one end of the lever S₁ extending. horizontally
across the machine in the rear of the disc the opposite end of which lever rests in a
slot in the ear of the girt T and is held against the end of said slot by the spring S³..
as shewn in Figure 21.
In a central hub of the girt T directly in the rear of and in line with the centre
between the lower part of clamping dies in the dise when at rest is mounted a testing
point w surrounded by a spring wwhich tends to move it away from the disc and
keep its head bearing against the lever S' as shewn in Figure 5.
A lever a having a cam-shaped inner edge to rest against the end of lever S¹ is
secured upon the lower end of a short vertical shaft x mounted in suitable bearings
and carrying at its upper end the stop pawl 2 which is made to engage with a
notch in the side of the shipper rod a' by the tension of the spring ³ coiled around
the shaft z¹.
At every forward movement of the bar G the end of the lever S¹ connected
thereto by the arm S is moved a given distance and causes the testing pin w to be
advanced into the hollow of the tubular shank of the stud, the other end of the said
lever remaining in contact with the end of the slot in the ear T¹ of the girt T, but.
if from any cause a stud should reach the position in front of the testing point w
without having its shank drilled out or only partially drilled out the point w when
it is moved forward by the lever S' comes in contact with the solid centre of the
stud and its forward motion is arrested, and as a consequence the middle of the
lever S' cannot move further toward the disc, but the pin w becomes a fulcrum
around which the lever S' moves, and while the end connected to arm S continues
to move toward the disc the opposite end is moved in the opposite direction and
acting upon the cam-shaped inner edge of the lever a causes it and the pawi 22 to
be moved outward, disengaging the shipper rod a and allowing the spring a² to act
to ship the belt and stop the machine.
U is a cutter headstock mounted and adapted to be reciprocated upon a dove-
tailed slide formed upon the stand U₁ secured to the cross ties of the legs B.
The cutter head U is fitted up with boxes, adjusting wedge and screws, hollow
spindle, furcated chuck head, hand wheel, driving pulley, and tubular coupling
spindle for operating the chuck head, all constructed and arranged as in the cutter
headstock M, except that no excentric sleeve is used in the headstock U.
Rotary motion is imparted to the spindle of the cutter head U by means of the
belt U leading from the pulley I³ to and around the pulley Us on said spindle.

page_text: The chuck head carries a cutter head and cutter, substantially like that shown
in Figures 24 and 25, and is arranged with its axis in line with the centre of the
lowest pair of clamping dies when the disc is at rest.
A reciprocating motion is imparted to the cutter headstock U. by means of the
cam-Clever and rod V1, said rod being made in two parts connected together
by means of the coupling sleeve-V-provided with right and left hand screw
threads in a well-known-manner.
A-spring-y-surrounds the rod V1 between the coupling sleeve V2 and the stand W
bolted to the underside of the cross-tie A3 of the frame A, and through which the
rod V1 passes, said spring serving to keep the cam truck on the lever V bearing
against the inner-wall-of_the_path in the cam C, and present a resistance to the
movement of the cutter headstock toward the-disc sufficient to prevent it from
jumping toward the disc in such a way as to injure the head of the stud:
The third part of this Invention relates to improvements in separating and
setting devices, whereby shoelace studs provided with hook heads or excentric
necks to receive the lacing cord can be automatically separated, arranged in regular
order, and fed separately and successively between the setting tools, with their
hooked heads always in the same direction, and it consists, first, in the use, in
combination with a hopper or receptacle into which the studs may be placed in
bulk, of a straight-edged plate or bar extending across the hopper, and adapted to
be reciprocated within said hopper from a lower to a higher elevation, and "vice
versa," in a path parallel to one of the sides of said hopper, at a distance there-
from about equal to the thickness of the outer portion of the stud head, said plate
or bar being made of a thickness slightly less than the distance between the two
collars, which with the excentric neck make up the hook head of the stud, all
arranged in such a manner that a movement of said. plate or bar up through the
body of studs will pick up more or less of said studs by their necks, with their
shanks all in one direction as the first step in the separation and arranging of said
studs preparatory to feeding them to the setting tools.
It further consists in the use in combination of a hopper into which the studs
may be placed in bulk and adapted to be vibrated from a horizontal to an inclined
position, and a straight-edged plate or bar of a thickness slightly less than the
distance between the two collars of the hook head of the stud, extending across
said hopper and adapted to be moved upward in a path parallel to one of the sides
of said hopper, at a distance therefrom a little in excess of the thickness of the
outer collar of the hook head of the stud, while the hopper remains in a state of
rest, then to be moved with said hopper into an inclined position, returned with
the hopper to a horizontal position, and then to be moved downward till its upper
edge reaches the lowest part of the hopper while said hopper remains in a state of
rest, as will be described.
It further consists in the use in combination with a hopper into which the studs
may be placed in bulk, and a device for picking up one or more of said studs by
their necks, with their shanks in one direction, and adapted to be tilted into an
inclined position, and to allow said studs so picked up to be discharged from said
hopper in regular order and in the same position, of a roadway or inclined chute,
the channel or groove in which, as seen in cross section, is shaped or corresponding
to the outline of the outer collar and the neck of the hook head of the stud when
cut in section through the centres of said collar and neck.
It further consists in the combination with a hopper into which the studs may be
placed in bulk, and a plate or bar of a thickness less than the width of the groove
between the two collars of the hook head of said stud, and adapted to be recipro-
cated while in a horizontal position in a path parallel with one of the sides of said
hopper so as to pick up one or more of said studs by their necks and carry them
upward to a given point with their heads all in one direction, and then to be tilted
with the hopper into an inclined position, of an inclined roadway or chute adapted
to receive said studs as they are discharged from said hopper, with their axes in a
horizontal position, and gradually turn them as they slide down said roadway into

page_text: an upright or vertical, or nearly vertical position, with their tubular shanks upward
and the hook sides of their heads toward the front of the machine.
It further consists in the combination of a cylindrical hopper mounted in a fixed
position in a pivotted frame adapted to be vibrated about its pivot so as to move
said hopper from a horizontal to an inclined position and "vice versa," a straight-
edged bar or plate secured to the periphery of discs or arms mounted upon a shaft
extending through the centre of said hopper and adapted to be vibrated therein in a
path concentric with the axis of said hopper from a point at the lowest part of said
hopper to a point about on a level with the axis about which said plate vibrates
"and vice versa," the edge of the said plate being of a thickness slightly less than the
width of the groove which forms the neck of the stud, and its outer surface being
at a distance from the inner surface of the cylindrical hopper slightly greater than
the thickness of the outer collar of the stud head, all so arranged that the passage
of the edge of the said straight-edged bar or plate from its lowest position to its highest
may cause one or more of the studs placed in said hopper to be carried upward
thereby, said studs hanging by their necks upon the edge of said plate with their
shank ends all pointing towards the centre of the hopper.
It further consists in the combination of a cylindrical hopper mounted in a fixed
position in a pivotted framo, a straight-edged bar or plate secured to the periphery
of discs or arins mounted upon a shaft extending through the centre of said hopper,
and adapted to be vibrated therein, a pulley secured upon the shaft upon which
said hopper is mounted, and an endless belt leading therefrom to and around a
pulley mounted upon and adapted to be intermittently oscillated or rotated back
and forth about the axis of said frame for the purpose of imparting to said bar or
plate an intermittent vibrating motion about the axis of the shaft.
It further consists in the use in combination with a cylindrical hopper mounted
in a fixed position in a pivotted frame a device contained in said cylindrical hopper
mounted upon a shaft having bearings in said hopper, and adapted to be moved
about the axis of said shaft and pick up and carry to a higher level one or more
studs, a pulley mounted upon said shaft, a belt leading therefrom to a pulley
mounted upon and adapted to be intermittently vibrated about a hub on the goose
neck concentric with the axes of a pair of binder pulleys mounted upon an excentric
shaft set in said frame, and adapted to be adjusted by turning said excentric shaft
to take up the slack of the belt.
It further consists in the combination with a cylindrical hopper pivotted frame, a
straight-edged bar or plate mounted upon and adapted to be vibrated about a shaft
having bearings in said hopper, a pulley secured upon said shaft, an endless band,
and an operating pulley, as above described, of a pin set in said frame or in the
cylindrical hopper, and two shoulders or lugs formed upon the hub of the pulley on
the shaft, or upon some other part connected to and adapted to be moved with said
shaft, all so arranged that said shoulders or lugs shall act in conjunction with said.
pin to limit the movement of said shaft about its axis in both directions.
It further consists in the combination of a cylindrical hopper, pivotted frame,
straight-edged bar or plate, oscillating shaft, its pulley, an endless band, an operating
pulley, a stop or stops to limit the extent of movement of said shaft, a separating
device, a lever secured to and projecting radially from the side of said operating
pulley, and provided with a slot, a pendent link provided with a pin to engage
with said slot, and having formed therein a curved slot which engages with a pin
set in a fixed position in the main frame of the machine to guide said link in its
upward and downward movements, said link being connected at its upper end to
and moved by the lever which operates the setting plunger and thereby imparts a
positive motion to the operating pulley on the axis of the pivotted frame in both
directions, and through the endless band to the shaft and bar or plate.
It further consists in the combination of a hopper, into which the studs may be
placed in bulk, a device operating within said hopper and adapted to pick up one
or more of the studs by their necks with their shank ends all in the same directions,
an inclined roadway or chute down which said studs may slide to the level of the

page_text: rest for supporting said studs while they are being set, and adapted to turn said
studs during their descent froin a horizontal to a vertical or nearly vertical position,
and deliver them at the foot of said inclined chute or roadway with the hook sides
of their heads towards the front of the machine and their shank ends upward, a
horizontal channel-or-guideway extending past the foot of the inclined chute at
right angles or nearly so thereto, provided with two upwardly projecting ribs or
lips-of a thickness slightly less than the width of the groove which-forms the neck
-of-the stud, the space between the inner edges of which is just sufficient to allow
the free passage of the neck-of the stud, while the groove immediately below said
lips-is-of-a-width just sufficient to allow the free passage of the outer collar of the
hook head and central with-the-narrower outer portion, so that the stud-cannot
turn upon its axis while being moved from the foot of said inclined chute to a
point beneath the setting plunger, and a device for moving said stud from the-foot-
of said inclined roadway to a point between the setting tools.
It further consists in the combination with a vertical reciprocating setting or
clinching plunger, a horizontal roadway provided with inwardly projecting lips ats
.its upper surface, and a reciprocating carrier or plunger adapted to feed a stud along
said roadway to a position beneath said setting plunger, of a stop adapted to limit
the forward motion of said stud and to serve as a support or anvil to resist the
downward pressure of the setting plunger while clinching the shank of the stud
upon the goods by fitting into the neck groove of the stud, and presenting a bearing
surface to the inner collar of the stud head without bringing any strain upon the
outer collar of said head to bend or cripple it or the neck of the stud.
•
It further consists in the combination with a horizontal roadway an inclined
roadway opening into said horizontal roadway at right angles or nearly so thereto,
and a reciprocating feed plunger adapted to feed a stud from the foot of said inclined
roadway to a point beneath the setting plunger of a sliding stop or abutment adapted
to close up said horizontal roadway just forward of the junction therewith of the
inclined roadway in a position to prevent more than one stud entering said hori-
zontal roadway at the same time, and to serve as a bridge or support for the inner
collar of the stud to rest upon and maintain said stud in a vertical position, and to
be moved to one side by the forward movement of the feed plunger to allow the
stud to pass to the setting tools.
It further consists in the combination with a hopper pivotted at one end and
adapted to be vibrated from a horizontal to an inclined position, and "vice versa,"
and an inclined chute or roadway with which said hopper is always in connection,
and about the end of which it vibrates, of a stop to limit the movement of said
hopper about its pivotal axis in a downward direction, as will be described.
It further consists in the combination with a reciprocating clinching plunger
operated by a vibrating lever, of a feeding plunger provided with a series of gear
teeth, a pinion adapted to engage with the teeth on said feed plunger, and mounted
upon a shaft adapted to be revolved in fixed bearings, a lever formed upon, or
-secured to said shaft, and a link or connecting rod attached by one end to the outer
or movable end of said-lever, and at the other end to the lever for operating the
setting plunger, all so arranged that the upward movement of the rear end of said
operating lever will cause the feed plunger to be inoved to the rear till its front end
is back of the junction of the inclined chute with the horizontal guideway, when a
stud moves from said chute into said guideway in front of the feed plunger, and
when the motion of the operating lever is reversed the feed plunger is moved toward
the front of the machine, carrying in front of it a single stud and depositing it in
the front end of the horizontal guideway directly beneath the setting plunger.

Similar letters indicate corresponding parts throughout these Figures.
A is the bed of the machine, from the rear portion of which rises the goose neck B,
extending forward over the bed A, and having mounted in its front end the setting
plunger C, connected by the link a to the forward end of the lever D, and adapted
to be moved vertically thereby for the purpose of setting or clinching a stud in the
material in a well-known manner, said bed being adapted to be secured upon a
table or bench of suitable height.
The lever D is pivotted at b to the upper side of the goose neck B, and its long
arm extends toward the rear of the machine and is forked, as shewn in Figure 1,
to receive the upper end of a connecting rod (not shown) the lower end of which
connects with the rear end of a treadle lever (also not shown) by means of which
the setting plunger is made to move cudwise in its bearings in a well-known
manner.
E is a forked frame provided at or near its front end with a journal c fitted to a
bearing in the goose neck B and held therein by the nut d, as shown in Figure 9,
and provided in the end of each of its forks with a bearing to receive the shaft F
upon which is loosely mounted the cylindrical hopper C which is secured in a fixed
position in the frame E so that it cannot revolve with the shaft F by means of the
key or lug e fitting into a recess in the frame E, as shewn in Figure 1, one portion
of said hopper being hinged to the other so that it can be opened to permit the
introduction of the studs.
The frame E is connected at its moveable or rear end by the slotted link U and
pin w with the rear end of the lever D in such a manner that an upward movement
of the rear end of said lever shall move the frame E and the hopper G into an
inclined position, the weight of said frame and hopper aided by the spring V causing
the frame and hopper to return to its normal or horizontal position when the lever D
descends.
Upon the shaft F within the hopper G are secured two discs or arms H, H,
connected together at their peripheries or outer ends by the curved plate or segment
of a cylinder H¹ made of a thickness slightly less than the height of the groove
which forms the neck of the stud, and adapted to be intermittently vibrated about
the axis of the shaft F moving through an arc of about 90 degrees, more or less
and in a path parallel with the interior surface of the hopper, and distant therefrom,
a distance slightly greater than the thickness of the outer collar of the stud head,
the whole being so arranged that when the plate H' is vibrated about the axis of
the shaft F so that the edge f thereof moves from the position shown in Figure 11
in the direction indicated by the arrow g to a point about on a level with the centre
of the shaft F, passing through the mass of studs (not shewn) placed in the hopper,
one or more of said studs may be picked up and carried upward by the edge j,
hanging by their necks thereon with their tubular shanks all pointing toward the
centre of the hopper.
'
One of the discs H has formed therein, directly opposite the edge f, an opening h

page_text: of such form as will permit the passage through the same of a stud when presented
thereto in the proper position, but not otherwise.
The head of the hopper immediately contiguous to the disc just referred to is
also provided with an opening i into which projects the tongue or lip i¹ in such a
position as to form an extension of the edge-f-of-the-plate H when it is moved into
its extreme highest position relative to the hopper G, all so arranged that when the
hopper and cylinder are tilted into an inclined position the studs which have been
picked up by the edge f of the plate H and are hanging thereon by their necks
- will be discharged through the openings and i with their shank ends all in one
direction and with the hook-sides of their heads downward.
•
The shaft F has firmly secured thereon the grooved pulley I, around which passes
the endless belt J which after passing around the binder pulleys K, K¹, mounted on
the eccentric shaft R set in a bearing in the frame E passes around the pulley L
mounted upon a hub c' of the goose neck B and provided with an arm having
formed therein the curved slot ¹ with which the pin h² set in the curved link M
engages, said link M being connected at its upper end to the plunger operating
lever D and guided in its upward and downward movement by the pin j set in
the frame of the machine and engaging with the slot j' formed in the said link, all
as shown in Figure 6.
The hub of the pulley I has a recess cut in its inner face so as to form two
shoulders, which coming in contact with the pink set in the frame E limits the
movement of the shaft F and plate H' about their axis of motion in either
direction.
M' is a standard set on the bed A which serves to limit the downward movement
of the rear end of the frame E and the hopper G mounted therein.
The eccentric shaft R is provided with a collar R¹ having formed therein one or
more radial holes, as shown in Figure 16, by means of which said shaft may be
moved about its axis to vary the position of the pulleys K, and K', and thereby take
up the slack of the said shaft, being secured in any desirable position by the set
screw u shown in Figure 5.
N is an inclined chute or roadway secured to and supported by the stand N' and
having an L shaped groove twisted spirally about ninety degrees and adapted to
receive the studs as they are discharged from the hopper with their axis in a
horizontal position and gradually turn them into a vertical or nearly vertical position
with their tubular shanks upward.
The chute N is also curved so that its lower end is at right angles or nearly so to
its upper end, by means of which, and the .twist in the path down which the studs
slide by the action of gravity thereon, the studs though discharged from the hopper
into the said chute with their axis in a horizontal position and the hook sides of
their heads downward are presented at the foot of said chute with their axes vertical
and with the hook sides of their heads toward the front of the machine.
O is a connecting rod adjustably attached by one end to the lever D, and by its
other end to the-lever. P made fast upon a short shaft o mounted in bearings in the
goose neck B and the detachable plate Q. The shaft o has secured thereon the gear
wheel p, the teeth of which engage with corresponding teeth formed in the upper
side of the feed plunger S, as shown in Figure 7.
The feed plunger S is fitted to and reciprocates in a groove or channel s formed
in the bed A, and extending past the foot of the inclined chute N, and at right
angles or nearly so thereto, that portion of said groove which lies between the foot
of the chute N, and the setting plunger being contracted at its top so as to form
upon cach side thereof an inwardly projecting lip q, each overhanging the under
portion of the groove immediately beneath said lip, a distance equal to one-half the
difference between the diameter of the neck of the stud, and the largest diameter of
the head; in other words, the groove beneath the lips being made of just sufficient
width to allow the free passage of the outer collar of the stud head, and the outer
portion of said groove or the space between the lips q, q, being just sufficient to
allow of the free passage of the neck of the stud, and located centrally with the

page_text: under portion directly beneath said lips, by which arrangement the stud is guided
from the foot of the inclined chute to a position under the setting plunger C, with
the hook side of its head towards the front of the machine, the form of the groove
in connection with the neck of the stud located excentrically to the outer head or
collar effectually preventing the stud from turning on its axis while being fed for-
ward.
T is a sliding block shown in plan and elevation in Figures 18 and 19 respectively,
and adapted to be moved in one direction by the spring, and in the other by the
feed plunger S, to close the channel 8 when the feed plunger is drawn back to the
rear side of the chute N, and form an abutment to prevent more than one stud
from entering the channel a in front of the feed plunger S at the same time.
8
The front end of the channel s is closed by a stationary abutment t provided with
a rearwardly projecting lip t', having formed therein a notch t², as seen in Figures
7 and 8, so that the outer collar of the hook head may pass under the lip t¹ of said
abutment, and the inner collar or head may rest upon the upper surface thereof
while the stud is being clinched; said abutment serving as an anvil to receive the
blow of clinching the same, a side opening s¹ being made from the channels to
permit the removal of the stud after it is clinched.
The feed plunger S is provided with a shoulder u¹ which engages with the pin x
set in the frame or bed A to limit the forward motion of the plunger.

the studs may be placed in combination with a straight-edged bar or plate fitted to
enter freely the groove cut in the said stud to form its neck extending across the
interior of the said hopper and adapted to be moved in a path parallel with a
portion of the inner surface of the hopper, and to pick up one or more of the studs
by their necks with their shanks all in one direction, and carry them to a higher
level, as and for the purposes described.
Twenty-seventh. The combination of a hopper into which the studs may be
placed and adapted to be vibrated from a horizontal to an inclined position, and a
straight-edged bar or plate extending across the interior of said hopper and adapted
to be moved up and down in a path parallel with a portion of the inner surface of
the hopper while the hopper is in a state of rest to pick up one or more of the
studs by their necks with their shank ends all in one direction, and to be moved
with the hopper as it is tilted into an inclined position, as above described.
Twenty-eighth. The combination with a hopper into which the studs are placed,
and a device adapted to pick up one or more studs by their necks with their shanks
all in one direction, and to be tilted into an inclined position with said hopper, of

page_text: an inclined chute or roadway having a groove or channel of an L shape, as shown,
adapted to guide said studs toward the setting tools and deliver them in a uniform
position, as above described.
Twenty-ninth-In-a-machine-for-setting-hook-headed studs the combination of a
hopper into which said studs are placed, a thin straight-edged bar or plate adapted
to be reciprocated therein in a path parallel to the inner surface of one side of said
-hopper, and to pick up by their-necks one or more of said studs with their shank
ends all in one direction, and to be tilted into an inclined position with said hopper,
and an inclined chute or roadway adapted to receive the studs as they are discharged
from the hopper with their axes in a horizontal position, and the hook sides of their
heads downward, and to gradually turn said studs as they slide down said chute
into a position with their axes vertical or nearly so with their tubular shanks
upward and the hook sides of their heads towards the front of the machine, as
above described.
Thirtieth. The combination of the cylindrical hopper mounted in a horizontal
position and adapted to be intermittently tilted endwise from the said horizontal to
an inclined position and back again to said horizontal position, the curved bar or
plate adapted to be intermittently moved from one position to another within the
said hopper, to pick up one or more of the studs by their necks while the said studs
rest on the edge of the curved plate with their shank ends all pointing toward the
centre of the hopper, as and for the purposes described.
Thirty-first. The pivotted frame, the cylindrical hopper, and the oscillating
curved plate, having the thin straight edge all arranged and adapted to operate in
combination to separate the studs, arrange them in the same regular order and
position, and discharge them successively from the said hopper, substantially as
described.
Thirty-second. The combination of the hopper, the shaft, the curved plate, the
frame, the pulley, the endless belt, the pulleys, the slotted lever, the curved slotted
link, the pins, and the lever, all constructed, combined, and adapted to operate as
above described.
Thirty-third. The combination in a machine for setting hook-headed studs of a
hopper, into which the studs are placed with their shank ends all in one direction
at each upward movement thereof, and to be tilted with said hopper into an inclined
position, an inclined chute or roadway adapted to receive said studs as they are
discharged from the hopper with their axes in a horizontal position and the hook
sides of their heads downward, and to gradually turn said studs as they slide down
said chute into a vertical or nearly vertical position, with the hook sides of their
heads towards the front of the machine, and a horizontal roadway extending across
or past the lower end of said inclined chute at right angles or nearly so thereto,
and adapted to guide the studs in their passage from the foot of said inclined chute
to a. position beneath the clinching plunger, and to prevent said studs from being
turned about their axes during such passage, as above described.
Thirty-fourth In combination with a vertically reciprocating plunger adapted to
clinch the tubular shank of the stud a horizontal channel or roadway of suitable
cross section to guide said studs by their necks and outer collars or heads, and
prevent them from being turned therein, a reciprocating plunger adapted to feed
said studs along said channel to a position under said clinching plunger, the
abutment provided with the rearwardly projecting lip and notch, all arranged and
adapted to operate as and for the purposes described.
Thirty-fifth. In combination with the horizontal channel or guideway the
inclined chute or roadway opening into the said channel at right angles or nearly
so thereto, and the feed plunger adapted to be reciprocated in the said channel, and
to feed a stud from the foot of the said inclined chute to a position boneath the
clinching plunger, the sliding block adapted to be moved across the channel just in
advance of the inclined clute by the spring, and to be moved back by the forward
motion of the feed plunger, as and for the purposes described.
Thirty-sixth. The combination in a stud-setting machine of a hopper pivotted at.

page_text: or near its front end, and adapted to be vibrated from a horizontal to an inclined
position, and "vice versa," and an inclined chute or roadway, about the end of
which said hopper vibrates and a stop to limit the downward movement of said
hopper, as above described.
Thirty-seventh. The combination of the clinching plunger, the lever, the con-
necting rod, the lever, the shaft, the toothed gear wheel or pinion, and the feed
plunger provided with a series of teeth upon one of its sides, all arranged and
adapted to operate as and for the purposes described.
