Figure 11 illustrates a modification of the device for separating a single stud
from a series arranged in line, and
Figures 12, 13, and 14 are views illustrating three different positions. of the
separating lever during the operation of separating the front stud or hook in a line
of studs or hooks from those in the rear of it..
A is the bed-plate of the machine arranged to rest upon a bench or table and
having cast therewith and projecting upward therefrom the goose-neck A¹ in which
is formed the chamber B to receive portions of the movable parts of the mechanism,
and to which access may be had by removing the side plate A2 secured thereto by
screws as shown, or by any other suitable fastening device.
C is the driving shaft mounted in. bearings in the pendent stands C¹.C² secured
to the under side of the bed A, the said shaft having firmly secured thereon so as
to revolve therewith the cams D and E,.and the collar F, and also having mounted
loosely thereon the pulley G provided upon the inner end of its hub with one or
more clutch teeth, (not shown) with which the spring-actuated dog G', pivotted to
the collar F engages, to compel the said shaft to revolve with the said pulley, all as
shown in Figure 5. H is a hopper of peculiar shape secured in a fixed position to
the side of the goose-neck or upper portion of the frame A¹ and provided with a
hinged cover H³, to permit access to the interior of the hopper for introducing the
studs or hooks to be set, and a slot through its bottom and extending from end to
end thereof through which slot moves the lifter plate H³ constructed as shown and
described, and mounted upon the short shaft I, about the axis of which the said
plate is vibrated edgewise, its 'curved edges, which are concentric with the axis of
the said shaft, moving in grooves a, a¹ formed in the curved end walls of the said
hopper as shown in Figure 2.
The opposite end of the shaft I has secured thereon the lever I' connected at its
movable end by the link I2 to the upper end of the lever 13 pivotted to the stand J
and carrying at its lower end a stud or truck which projects into and is acted
upon by the path D¹ of the cam D to impart thereto and through the link 1²
lever and rock-shaft I to the lifter plate H2, a vibratory motion.
The hopper H is also provided with an opening in its front curved end wall of a
size and shape corresponding to an elevation of the lacing stud or hook to be
operated upon by the machine, when viewed from the side with its neck upper-
most, the said opening being so located in the said hopper that a stud or hook
hanging by its neck upon the upper edge of the plate H2 will slide therefrom,
and through the said opening, when the said plate has reached the extreme of its
upward movement.
K is a curved inclined chute, composed of three plates'k, k¹, k² arranged relatively
'to each other as shown in Figure 10 of the drawings and secured to the stand K¹,
bolted in a fixed position to the goose-neck A¹ the upper end of the said chute
being so located relatively to the opening in the side of the hopper that the studs or
hooks where discharged from the said hopper shall be received by the said chute
and guided thereby in their passage till they are discharged from its lower end.
L is a lever pivoted to the goose-neck A¹ at 6 and having formed in the end of
its short arm, which projects through a slot in the said goose-neck, a peculiarly
shaped slot c adapted to receive the head of a stud'or hook as it slides down the
inclined chute K and is discharged from its lower end, the neck of said lacing stud
or hook resting upon the point of the hook d of the said lever as shown in
Figures 12, 13 and 14.
The short arm of the lever L is made of sufficient thickness to permit but one
lacing stud or hook to enter the slot c and rest upon the hook d at a time, and of
such width above the slot c as to serve as a guard to prevent the remaining lacing
studs or hooks upon the chute K from being discharged therefrom until the slot c

page_text: is again brought into a position opposite the end of the said chute after having
been depressed to discharge the lacing stud or hook previously received from the
Baid chute.
. :
The hook d of the lever L lies between and in the same plane with the upper
ends of the guiding plates ee of the curved roadway L' which plates extend
downward and forward from the end of the chute K to the setting tools, and receive
the lacing studs or hooks from the lever L when its short arm is depressed and
guide them to the setting tools in the desired position to be acted upon thereby.
The plate e upon the side of the roadway L¹ opposite to the lower end of the
chute K extends upward to a point as high as the top of the slot c in the lever -L
when the short arm of the said lever is raised to its highest position and serves as
an abutment to check the movement of the lacing hook or stud when it is dis-
charged from the chute K, a portion of the head of the stud or hook passing behind
the said plate while the inner collar of the head is outside or in front of the said
plate so that as the short arm of the lever L is depressed the two plates e embracing
the neck of the lacing stud or hook compel it to follow the roadway L' in its
downward movement, and as the hook d of the lever L moves downward in a path
curved in a direction opposite to the curve of the roadway L', it follows that the
hook d of the lever L will be withdrawn from the neck of the lacing stud or hook
thus allowing the said lacing stud or hook to descend the curved roadway L' to a
position to be struck by the reciprocating plunger M. and be fed thereby into a
position between the setting tools.
The rear or long arm of the lever L has set therein a stud or pin f; shown in
dotted lines in Figures 2 and 3, which projects over and is acted upon by the
movable end of the horizontal arm of the elbow-lever N the other arm of which is
struck, at each revolution of the main or driving shaft, by the anti-friction roller g
mounted upon a stud set in the side of the cam. E in a position excentric to the
axis of the said cam and arranged to revolve about the said axis, and by contact
with the pendent arm of the lever N to cause the horizontal arm of the lever N
and the long arm of the lever L to be raised, and the short arm of the lever L to.
be depressed.
When the roller g has passed the short or vertical arm of the lever N, the extra
weight of the long arms of the levers L and N acted upon by the force of. gravity
cause the said levers to assume their original positions.. If desired a spring may be
applied to the long arm of the lever L to ensure the return of the said lever to its
original position in proper time to receive another lacing stud from the chute K
before the lever N is again struck by the roller 9:
"
The extent of vibration of the levers L and N is limited in an upward direction
by the pin f striking the shoulder h formed in the interior of the chamber B of the
goose-neck A¹ and in a downward direction by the free end of the horizontal arm
of the lever N resting upon the ledge h¹ in the same chamber as shown in
Figures 1 and 3.
.
The horizontal feed plunger is made in two parts M and M², the latter in the
form of a plunger fitted to a hole bored in the rear end of the former so as to work
therein like a piston, and the two parts are connected by the pin i set in the part M
and passing through a longitudinal slot i' in the part M' so that a limited amount
of movement of the part M' within the part M inay be permitted in case of an
obstruction interfering with the proper movement of the part M; a spring ; is
inserted between the inner end of the rod M' and the bottom of the hole in the
part M in which it works, which spring is of sufficient stiffness to insure the proper
feeding of a single stud or hook to the setting tools when properly presented and is
adapted to yield so as to permit the revolution of the operating cam without
breaking the machinery if any obstruction prevents the part M from completing its
stroke.
O, is a connecting rod or link coupled at one end to the rod M' and at its other
end to the upper end of the lever P, having its fulcrum upon the stand. P¹, secured'
to the underside of the bed A and carrying at its other end a truck 7, which fits

page_text: into and is acted upon by the path D2 of the cam D to impart to the feed
plunger M, M, a reciprocating motion, all as shown in Figures 1, 3 and 5.
In setting tubular rivets it has been common to use a carrier provided with a
pocket to receive the head of the rivet as it was delivered thereto from the chute,
the said carrier moving with the setting plunger to guide the rivet to the proper
position in contact with the stock, when the movement of the said carrier ceased, and
the setting plunger continued its motion to force the rivet endwise from the carrier
through the stock and to clinch the same, the said setting plunger acting directly
upon the head of the rivet.
The setting of a shoe lace stud or hook having a tubular shank presented however
a different problem, as the pressure required to set the stud, could not be applied
directly to the end or outer head of the hook or stud without ruining the said hook
or stud, and therefore it became necessary to so construct the anvil that the pressure
for forcing the shank through the material and clinching it, should be applied to
the inner head or disc of the stud or hook.
To this end the anvil was provided with a pocket or recess cut in its side to
receive the outer head of the stud or hook and a slot cut from the said pocket to
the end of the anvil, and the said anvil was arranged in a fixed position with its
pocket and slot coinciding with the end of the road-way through which the book
or stud was fed thereto, in which position it remained till the stud or hook was
clinched.
When this was done the bead of the hook or stud was fast in the anvil and could
only be removed by raising the anvil by hand after the shank had been clinched,
or by opening the sides or front of the pocket...
To obviate the necessity for lifting the anvil as above described or making the
anvil with spring jaws which would open to permit the withdrawal of the hook or
stud from the anvil after it was clinched to the material, I set the clinching tool m
in the threaded spindle Q adjustably secured in the goose-neck A' by the nuts Q'
and Q and prevented from turning in its bearing, while being adjusted, by the set-
screw n, the point of which enters a short groove cut in the side of the spindle as
shown in Figures 2 and 3.
I also attach the anvil o and its cap o¹, secured thereto by the set screw o², to a
vertically reciprocating plunger R set in a bearing in the bed plate A and the
upper portion of the stand S, bolted to the under side of the bed plate A and
projecting downward therefrom.
The front portion of the stand S has formed therein the slot S¹ and the rear
portion has formed therein a bearing for the reciprocating bar S2 which carries at
its rear end a truck fitting into and acted upon by the path E¹ of the cam E and
connected at its front end to the link p which in turn is coupled to the toggle
links p, p, the opposite ends of which are connected respectively to the plunger R
and the adjustable stud T set in the lower cross-bar of the stand S as shown in
Figures 3 and 4.
The anvil o has formed in its upper end a recess extending from the rear side
thereof toward the front of suitable shape and size to receive the outer head of the
lacing stud and permit the stud to be fed to a position in axial line with the
setting tools and no farther while the cap o' has a slot cut through its rear upper
corner of a shape to receive the outer head and the neck of the stud while the
inner head or collar of the stud rests upon the top of the anvil cap o¹ in a well
known manner.
U is a shipper bar mounted in a bearing in the stand C2 and carrying at one end
the ring U firmly secured thereto and surrounding the inner hub of the loose
pulley G just inside of the upright portion of the dog G' and having at its opposite
end a truck or stud which engages with the detent notch q formed in the edge
of the annular rib E' cast upon the side of the cam E
V is an elbow lever pivotted at r to the cap of the stand C³ and connected at
one end to the bar U and at the other end to the rod V₁ the lower end of which
is connected to a treadle (not shown), by depressing which the bar U may be

page_text: moved towards the pulley G carrying with it the ring U₁ and removing the locking
pin or truck from the detent notch thus allowing the dog G' to be moved by its
spring into a position to be engaged by a tooth on the hub of the pulley G and thus
cause the shaft C to be revolved. The treadle is moved upward by a spring (not
shown) of sufficient power to move the treadle, the rod V', the lever V, the bar U,
the ring U', and the dog G¹, against the resistance of the spring which actuates
the dog to move it into engagement with the pulley G.
In Figure 11 illustrating a modification of the hook-separating device, W is a
wheel having formed in its periphery a series of slots or pockets c, c, of the same
shape as that shown in the lever L; the said wheel is adapted to be mounted upon
the same axis as the lever L and to be intermittently moved about the said axis in
the direction indicated by the arrow, by means of the lever W¹ mounted loosely
upon the said axis, the pawl s pivotted to the said lever, and the ratchet wheel W
secured to the wheel W or to its axis so that the two wheels W and W2 shall be
compelled to revolve in unison.
The peculiarity of the shape of the hopper H is clearly shown in Figures 5
and 6, by examining which it will be seen that it has one straight vertical side,
contiguous to which the segmental plate H³ moves up and down, (vibrating about
an axis located outside of the said hopper,) two curved sides parallel to each other
and concentric with the axis about which the said plate vibrates, and a fourth side
the upper portion of which is parallel with the straight vertical side and the lower
portion of which is curved inward so as to approach much nearer to the said
straight side than the said upper portion, whereby the studs or hooks contained
therein are concentrated in a narrow space at the bottom of the hopper in position
to be taken up by the upper edge of the plate H2; as it is moved upward from its
lowermost position, that is to say, with its upper edge flush with the interior of
the bottom of the hopper the said position being shown in dotted lines in
Figure 6
The upper edge of the plate H2 is rebated or reduced in thickness upon the side
next to the straight vertical side of the hopper to form a space for the outer head
or button of the stud or hook when it hangs upon the said plate by its neck with
its tubular shank projecting horizontally therefrom towards the centre of the
hopper..
By the construction and arrangement of the hopper and lifting plate as above
described the passage of the plate H' upward through the mass of studs or hooks
contained in the hopper H will cause certain of the studs or hooks to be carried
upward thereby hanging by their necks upon the edge of the plate H2 with their
shank ends all in one direction and pointing away from the straight vertical wall
of the hopper, and when the said plate. has reached the limit of its upward
movement or its upper edge is inclined towards the opening in the hopper, the said
studs or hooks will slide down the said plate through the said opening in the
hopper and down the inclined chute.
If any studs or hooks are carried upward by the said plate that are not hanging
by their necks as above described they will be thrown therefrom as the plate rises,
and fall into the hopper to be again taken up by the said plate at some subsequent
upward movement thereof
The lifting plate H' is shown in the drawing with its upper edge rebated or
reduced in thickness so that it may enter the space between the head or collar of a
lacing stud or hook, and form a space between the said upper portion of the plate
and the straight vertical wall of the hopper to receive the head of the stud or
hook which hangs by its neck upon the said plate, the main body of the said plate
being made of such thickness that it is contiguous to the said straight vertical
wall, but it is obvious that the said plate may be of an even thickness throughout,
not greater than the distance between the head and collar of the stud or hook, and
be located at a distance from the vertical wall of the hopper equal to or slightly.
greater than the thickness of the stud head without departing from the principles
of the said invention.
