page_text: 1, JAMES ABERCROMBIE BURDEN, of Woodside, in the City of Troy, County of
Rensselaer and State of New York, United States of America, Iron Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to bo
performed to be particularly described and ascertained in and by the following
statement:-
My invention relates to certain improvements in machines for making horse-shoes,
and more particularly to that class of such machines as are adapted by their construc-
tion to produce shoes from a bar of iron that has previously been shaped, and
rolled by other mechanism; and which bar as re-heated is passed.in to the mechanism
to be by it cut into proper lengths that by a connected mechanism are swaged into
form; with the creasing for the nail-holes, and the punching of the latter accomplished
by another and disconnected mechanism.
My improvements upon this older class of machines have for their object; first,
to give by means of a continuously moving mechanism to the heated and entered bar
from which the shoes are made (through the action of the rolls and other machinery)
regular alternating periods of motion and rest; second, to put in the nail-creases at
proper blank-lengths apart in the bar and to progressively move it while so creasing it.
Third: to rough-punch in succession the blank-lengths for the nail-holes where
previously creased therefor, and while thus rough-punching it to progressively
operate upon the bar to move it a blank length; Fourth, to full-punch in the blank-
lengths of the passing bar the nail-holes; Fifth, to cut off the bar at proper blank-
lengths; Sixth, to bend and shape the blanks into the required form; Seventh, to
remove the completed shoe from off the frog-form die on which it has been shaped
and swaged; all of which several operations are done in connected sequence and by
a continuously operating mechanism.
My invention consists (as will be more fully detailed hereinafter in connection
with its illustration) of two creasing rolls, that are constructed to be connectedly
rotated, and with both of said rolls having operative perimetral segments which as
the rolls are rotated will thereat engage with, and so as to move with expelling force
an entering bar of heated iron; one of said rolls having upon its operating segmental

page_text: face, blades that are adapted to enter the face of the bar, and produce therein the
crcases for the nail-holes, while said rolls are engaging with the bar; said rolls each
being upon its perimetral face where between said operating segments cut away to
have a shorter radius thereat, and so that as the creasing rolls are continuously
operated the segments thereof having the greatest radius as they approach each other
in revolution will engage with the bar to crease it, and to move it with expelling
force and that part of the perimeter of the said rolls having the shortest radius when
approaching each other will pass over the bar without engagement therewith;
thus giving to the bar while creasing it regularly alternating periods of motion
and rest.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) of two rough-punching rolls that are connected and constructed
to be continuously operated when the machine is running; one of said rolls having in
its perimetral face a segment containing a groove that is parallel to the sides of
the roll, and which groove has punches that are projected radially from the bottom
thereof, and with the perimeter of said roll where between the ends of the said punch-
segments cut away to have less radius thereat than at the punch-segments; and the
other one of this pair of rolls having a die-segment in its perimeter containing, sinks
that are adapted to come radially coincident with the punches in the punch-segments
of the other roll when the two rolls are rotated; and with the circumferential face of
each of said rolls where between the said operating segments cut away to have less
radius thereat, and so that as the rolls are rotated the punch-segments of the one, and
the die-segments of the other roll, will as they approach each other engage with the
bar to rough-punch it, and at the same time to move it with alternating periods of
motion and rest.
.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) of finishing-punches that are operated for completing the punching
of the nail-holes, and for the removal of the burrs formed on, the bar, oppositely to
where rough-punched; these finishing punches being arranged in series that are
connected and adapted to be together vertically reciprocated at one of the periods
when the bar is at rest after it has been shaped, creased, and rough-punched at
regular blank-lengths; such finishing punches being constructed and arranged to be
operated in connection with a die-plate having holes therein that are vertically in line
with the finishing punches, between which latter and the dieplate the heated bar
moves, and so that when the latter is in such a position each one of the finishing-
punches will be operated to enter one of the previously roughly punched holes in the
bar, and in passing through the latter to enter the die-plate and thus punch out and
cut off the burr left on the bar by the rough-punching, and after doing which the
finishing punches will move away from the bar to repeat the operation when another
blank-length of the bar is again brought into position.
My invention also consists (as will be more fully detailed hereinafter in connection
with its ilustration) in the combination with a mechanism that is constructed to shape,
crease, rough-punch, and finish-punch a heated bar for making horse-shoes, and to
move said bar with alternating periods of motion and rest; of a cutting mechanism
that is adapted and arranged to cut the bar into proper lengths after it has been
creased, rough-punched, finished punched and before entering the swaging and
shaping machinery.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) in the combination with a die-wheel having frog-form dies upon its
perimetral face, and actuated so as to be continuously revolved; of two bending levers
each of which is constructed back of where pivoted with a spring arm, and a cam
engaging arm having upon its end a friction roller; a spring connecting the spring
arms of the bending levers back of where pivoted; and said bending levers so placed
with reference to said die-wheel that as the latter is revolving each of the frog-form
dies thereon will pass between the bending levers where at the outer ends provided
with bending rollers; said bending levers being actuated by a cam roller that is
provided with a cam upon each of its ends, and so placed that the said cams will

page_text: simultaneously engage with the bending lever cam arms back of where pivoted, so as
to thereat spread them apart against the recoil force of the connecting spring and so
cause the front ends of said levers where provided with bending rollers to more
positively come in contact with and follow around on the curved sides of each of said
frog-form dies in passing, or to engage with a blank thereon to shapo the latter, and
close in its heel ends around the die.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) in the combination with a die-wheel having constructed upon its
perimetral face at regular distances apart frog-form dies, the base plate of each of
which is flat and laterally without curve, said die-wheel being operated to rotate
continuously; of a roller constructed with sinks in its cylindrical face, said sinks cach
having interiorly the exterior form of the frog-form dies of the die-wheel slightly
elongated, and exteriorly made with rim plates that project from the face of the roller
surrounding the sinks; the outer surface of which rim-plates each curve eccentrically
from that of the roller, with said sink roller actuated to revolve continuously with
varying speed of rotation, and in such a manner relatively to the movement of the
die-wheel that each of the frog-form dies of the latter shall enter one of the sinks of
the said roller, and each of the projecting rim-plates of the sinks will make a tangent
engagement with the outer surface of a horse-shoe resting on the flat base-plate of ono
of the frog-form dies, and when thus passing along over it to remove from the shoe.
any lateral curling, or buckling that may have occurred to it, during the operation of
bending.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) in the construction of the parts of the mechanism performing
the several functions of entering the bar, creasing it, rough-punching it, full-punching
it, cutting off the bar, and for bending the latter so that said several parts performing
these functions may be laterally adjusted towards or from each other upon the bed-
plate to adapt the mechanism to operate upon blanks of varying lengths so as to
produce horse-shoes of differing sizes.
My invention also consists (as will be more fully detailed hereinafter in connection
with its illustration) and as will be set forth in the claims, in the sub-combination
of the parts illustrated, and described where such parts perform specific function.
Accompanying this specification to form a part of it there are eight plates of
drawings containing thirty four figures illustrating my invention, with the same
designation of parts by letter reference used in all of them.

form dies that is in advance of the blank shown as just entered and which bent shoe
is illustrated as being flattened out laterally on the flat base-plate of the dio which it
encircles by the tangent engagement, with the top surface of said shoe of the rim-
plate of the sink on the sink-roller in which the frog-form die the shoe encircles has
entered to pass out of.
Figure 16 shows the same parts of the mechanism that are illustrated at figure 15,
but with the rim-plate of one of the sinks having nearly finished flattening out and
laterally straightening a bent shoe, and another cut-off blank about to be caught
(after having been entered) between a succeeding one of the frog-form dies, and the
pivoted bending levers. Figure 17 is a side elevation of the uppert part of the
die-wheel, an end view of the sink-roller and the cam formed thereon, a side view of

Figure 34 shows as detached a part of the frame of the punching mechanism.
The several parts of the mechanism thus illustrated are designated by letter
reference and the function of the parts is described as follows: The letter P indicates
the driving pulley, S¹ its shaft, and G¹ a gear-wheel arranged thereon to turn with
said shaft. This gear-wheel G¹ meshes into a gear-wheel G3 on the shaft S³, by
which power is communicated to the entering or shaping rolls, the rough-punching
rolls, the creasing. rolls, the full-punching mechanism and the cutting mechanism
as will be hereinafter detailed. The letter G³ designates a gear-wheel that is arranged
on the same shaft as the driving pulley, and this gear-wheel G³ meshes into a gear-
wheel G on the shaft S to actuate the die-wheel D¹, and the letter G designates a
gear-wheel on the die-wheel shaft that meshes into the gear-wheel G on the shaft $10
of the sink-roller R', to actuate the latter.
The letters F designate the frame parts of the machine, and the letters H the
housings of the roll mechanism. The letters R³ designate the upper one of the two
entering and shaping rolls, and R³ the lower one of them. Power is communicated
to the lower one of these shaping and entering rolls by means of a bevelled gear g²
on the shaft S thereof, and the bevelled gear-wheel g¹ on the shaft S³. These entering
and shaping rolls are each provided with a gear g³, arranged. to mesh into each other,
and by which motive power is communicated from the lower roll that receives the
power, to the upper roll. The entering and shaping rolls have their bearings in
the housing H, and the rolls proper project beyond the latter.
Each of these shaping and creasing rolls are made with two segmental parts to
their perimeters, one of the segments in each roller having a greater radius than
the other, and with the differing segments upon each of the rolls arranged to meet
as the rolls are rotated so that when the segments of each of the rolls having the
greater radii come together they will engage with an entered bar to move it
progressively, and at the same time to shape it if desired; and then as the segments
of the rolls having the shorter radii approach each other in the revolution of the
rolls, the latter thereat will pass over the entering bar without engaging with it,
and as thus constructed and operated continuously the rolls will give to the bar
regular periods of progressive movement and alternating periods of rest. When
these rolls R2 and R³ are used simply as entering rolls then that perimetral face
of the lower roller having the longer radius has a recess in revolution formed
therein corresponding to the cross-sectional form of the bar to be used, said groove
being indicated at g3. When it is desired to use these rolls for shaping the interior
edge of the shoe so as to produce a concave thereat, or so as to make snow or mud
shoes, then the lower one of them is constructed to have the shaping bevel 1, as
shown at figures 20, 21, and 22, with the perimeter of the upper roll plain in its
surface and without recess.
The letters R and R designate the creasing rolls, and these rolls are operated
by the bevelled gear g¹ on the shaft S2, and the bevelled gear g³, on the shaft of
the lower one of the creasing rolls, and the connecting gears 96 on the said rolls R
and R. These creasing rolls are also made with two differing segmental parts
upon their perimeters; one of said segments in each roll having a greater radius
than the other, and with said differing segments upon each of these rolls arranged to
meet as the rolls are rotated, so that when the segments of the rolls having the
greater radii come together they will engage with the entered bar to move it pro-
gressively, and at the same time to crease it for the nail-holes and then as the segmental
parts of the rolls having the shorter radii approach to meet in the revolution of the
rolls, they will pass over the bar without engaging with it.

page_text: The lower roll R, of the creasing rolls where having the greatest radius upon its
perimeter is constructed with blades, that are upwardly projected from the bottom
face of the groove g¹³, made in said roll thereat, and the perimeter of the upper roll R³,
is made plain on its perimetral face where having the greatest radius, so that when
the two creasing rolls are rotated with their segments having the greatest radii in
contact, the blades ¹, will cut into the lower surface of the bar as moved progressively
by the rolls the nail-creases.
The letters R, and R?, designate the rough-punching rolls, and these rolls are
actuated by the bevelled gear n³, on the shaft S2, the bevelled gear n² on the shaft
of the lower one of the rough-punching rolls, and the connecting gears n³ on the said
rolls R and R. These rough-punching rolls like the entering and creasing rolls are
constructed with perimetral segments having a greater radius than the rest of their
perimeters and with the differing segments of each roll arranged to meet as the rolls
are rotated so that when the segments having the greater radii come together they
will engage with the entered bar to move it progressively, and at the same time to
rough-punch it; and then as the parts of the rolls having the shorter radii approach
in revolution to meet they will pass over the bar without engaging with it; and thus
these rough-punching rolls also give to the bar periods of progressive movement and
alternating periods of rest.. The lower roll Re of these rough-punching rolls, upon
the segment having the greatest radius, has two series of punches p₁, consisting of
four each; and these punches are radially arranged in the roll and project beyond the
face of the groove g³, formed in the perimetral face of said roll R. The segmental
face of the upper roll R7, where having the greater radius made with the sinks d¹,
and these are radially placed therein so that as the rolls are rotated each one of said
sinks in the upper roll will come perimetrally opposite one of the punches of the lower
roll R. These rough-punching rolls are shown in detail at figures 29, 30, 31, 32, 33.
As thus constructed by the cooperation of the punches in the lower roll, and the
dies in the upper roll, the bar is rough-punched in the nail creases previously formed
therein, and the metal displaced by the entering punches is passed through the bar to
appear as a burr on its upper surface.
The grooved segments in each of the three sets of rolls thus described are preferably
made of such cross sectional area as will somewhat elongate the bar in its passage and
reduce its cross sectional dimensions; and where it is desirable to have the blank
lengths of the bar of uniform size, at what are their ends when cut off, the first set
of rolls should be keyed onto their respective shafts so as to engage with the bar a
little in advance of where the creasing rolls will engage with it; and the latter rolls
should also be keyed to their respective shafts so as to engage with the bar, a little
ahead of the rough-punching rolls, while the rough-punching rolls should be so keyed
to their respective shafts as to have the latter rolls engage with the passing bar a little
in advance of the creasing rolls with the punches and dies of the rough-punching rolls
so arranged in their engaging segments as to have them come together in diametrical
contact, at proper positions within the nail creases previously formed in the bar, as
indicated by the dotted line d of figure 2.
The letters p³ designate two series of punches for full-punching the shoe-lengths
of the bar, and these series of punches are placed relatively to each other, so that
the two series shall be the same distance apart as the two series of rough-punching
holes made at intervals in the bar by the rolls as before described; and the full-
punches of each series are placed in the same distance apart, and, so as to enter the
holes in each series that have been produced in the bar by the rough-punching rolls.
The letters p² designate the full-punching dies of which there are two series, each
arranged to be vertically in line with each series of the full-punches. As shown at
figures 1, 2, 6 and 9, there are two sets of these full-punches, and two sets of full-
punching dies with each set of full-punches, and each set of full-punching dies
arranged to turn on separate shafts so as to be reversable, for repairing or allowing
the punches to cool should they become over heated, and in the modification shown at
figure 11 there are four sets of full-punches, and four sets of full-punching dies, each
radially arranged on separate shafts adapted to interchangably operate. The letters S8,

page_text: designate the shaft on which the full-punching stocks m³ are turned to reverse, and S
the shaft on which the stocks m³, carrying the full-punching dies d¹, are turned to
reverse. The letter W as indicated at figure 6 designates a securing key provided
with a hand-wheel w, which key is threaded into the frame F1, and so that when it
is screwed into and through the frame it will enter the hole Omade in the sliding
frames m2, carrying the stocks and full-punches, and thus secure the parts after
being reversed, and turned on their shaft connection; and the letter W, designates
a key stop having a shaft 63 that is threaded into the frame F', and which when
screwed through the latter will enter a hole O made in the ears E6 of the stocks m³,
of the full-punching dies, to secure them in position after being reversed and turned
on their shaft connection.
The letter W designates a gear-wheel keyed to, and so as to turn with the shaft S*,
and W is another gear-wheel meshing into the latter wheel and having a shaft N1,
turning in bearings in the frame F, as shown at figure 9. The letter designates
a V-form crank arranged to receive power from the shaft N¹ on the wheel W, and P12
a pitman which at its upper end is constructed to pivotally connect with said crank C,
and at its lower end e to pivotally connect with the end of the lever L', as shown
at figures 2, 3 and 9. This lever is V-shaped as indicated at figure 10, and at its
outer end it is arranged to turn on the fixed shaft or bar A, as it is reciprocatingly
oscillated by the combined action of its connection with the pitman P, and the
crank connection which the latter makes with the wheel W4.
The letter U indicates a web connecting the two arms I¹ of the lever L¹ and the
letter Jindicates a web or cross bar connecting the two vertical sides of the slide
frame m, that carries the full-punching stocks m², and also the two series of
full-punches p². The letter L2 designates a link which at its upper end jis
journalled on to the web or cross bar J of the sliding frame, and at its lower
end it is journalled on to the arms I¹ of the lever L' as shown at figures 6, 7
and 9. When the lever L as thus connected is operated it moves reciprocatingly and
vertically the slide-frames m¹², carrying the full-punching stocks and punches
upwardly, in the slides of the machine frame (said slides being indicated by the
dotted line d of figure 6) and so as to force the punches to enter the holes before
rough-punched in the bar Y¹ by the rolls, and so as to punch out the burr left on
their upper surfaces, while the bar is at rest, and to then move away from the
latter.
The letter E designates a bevelled gear on the shaft S²; and E² a bevelled gear
on the shaft N2, which gear engages with said bevelled gear E². The letter E³
designates a bevelled gear on one end of the shaft N2 that is opposite to that at
which it receives power from the shaft S2. The letter E designates a bevelled
gear on one end of the shaft N³, that meshes into the bevelled gear E³; and E
a bevelled gear on the other end of said shaft N³, which meshes into the bevelled
gear E, on the shaft N4, operating the cutting mechanism, as shown at figures 3, 12
and 13.
The letter C2, as shown in detail at figures 3, and 13, designates the cutter arm
of the cutting mechanism, and c³, a pivot on which it is adapted to be. oscillated.
The letter e, designates a cam arranged on, and so as to turn with the shaft N³;.
and C, a tappet foot constructed on the outer end of the cutter arm (2, at its
bottom whereby as the said shaft N³, and the cam thereon are turned, said front
end of the cutter arm is actuated to descend, and bring into action a blade B³,
that is downwardly projected therefrom. After the cutter arm and blade are thus
caused to descend they are (as the cam turns so as to cease its engagement with
the tappet) caused to ascend on the pivoted connection at c³, by means of a spring
connected with the rod 75, said spring not being shown in the drawings.
The shaft N, before named has its bearings at 65, 66, in the pivoted frame-part F³.
The letter e, designates a shaft having its bearings at 7, in the frame-part F2, as
shown at figure 3, and the letters c, designate gears arranged on the shafts N,
and c, to communicate motion from one to the other of said shafts, and a roller c
on the outer end of each of the latter, between which rollers the bar to be cut
,

page_text: off passes, and which rollers when engaging therewith co-operate to move the bar,
and the lower one of which rollers is adapted (when the cutting blade is descending)
to drop down from its engagement with the bar as will be subsequently described.
The blade B2, is projected downwardly from the cutter arm C2, towards the anvil
or plate 3, whereon the bar is cut as shown in part at figures 1 and 3, and in
detail at figure 13.
The letters designates a link that is pivoted to the cutter arm (at 10, and
at its upper end is secured to the cutter arm by a bolt passing through a slot 2, as
shown at figure 13, and which slot allows the said link to move on its pivot at 76,
to the extent of the slotted opening, for the adjustment of the cutter arm. The
letter designates another link that is pivoted to the frame-part F3 shown as detached
at figure 34, and which frame-part F³, is also pivoted at 10 to the frame-part F2;
the upper end of said. link 7 being pivoted to the link at . The function of these
links and their connections is to move downwardly the frame-part F³, on its pivoted
connection and also the outer end of the shaft N having its bearings in said frame-
part, so that the roller c8, on the outer end of said shaft N, will drop down a little and
so as not to engage with the bar while the blade B2 is descending. The cutting
mechanism thus described considered apart from its combination with the parts
performing connected functions I make no claim to herein.
•
The die-wheel D' has formed on its perimeter at regular distances apart the frog-
form dies d, which on their exterior faces are curved at f, and each of them is
constructed with a flat base-plate p³, having no lateral curve. This die-wheel as
shown in detail at figures 14, 15, 16, 17, is constructed to be continuously operated
when the machine is running, and by means of the gear-wheel G³ on the driving
pulley shaft which meshes into the gear-wheel G on the die-wheel shaft S³. This
die-wheel and the frog-form dies constructed thereon is shown at figures 1, 2 and 3,
and in connection with the other mechanism with which it immediately connects at
figures 12, 14, 15, 16, 17 and 18.
The
The letter designates the sink roller, and S10 its shaft, the latter having its
journal bearings at m³, m³, in the housing H, and with the sink roller located above
and a little towards one side of the vertical diametrical center of the die-wheel.
letters designate sinks having an interior form corresponding exteriorly to that part
of the frog-form dies that is outside of the base-plate but somewhat longer than the said
dies thereat; and these sinks are of such size that the frog-form dies, where projected
beyond the base-plate thereof, will enter the sinks while the die-wheel and the sink-
roller as relatively placed are rotated together.
The letters indicate rim-plates that are outwardly projected from the roller faco
around each of said sinks, so as to border them on their edges at all parts excepting
the heel-part. On their outer face these rim-plates in their contour from the
cylindrical face of the roller, have the form of a flattened crescent in section, and as
shown at figure 12. This sink-roller is operated by the gear-wheel G, and
this gear-wheel has the pitch-line of its gears differentiated at intervals and as
shown by the dotted line 20 of figure 5. The gear-wheel G which actuates
said gear-wheel G has the peripheral line of its gear tips so differentiated circum-
ferentially, and at regular intervals as to cooperate with the construction of the gears
upon the wheel G to move the said sink-roller, at certain intervals more rapidly than
at others, and more rapidly than the die-wheel and so that the rim-plates each of
them will as turning with the sink-roller make a continuous tangent engagement with
a shoe (upon the base-plate of each of the frog-form dies) to straighten it out, and to
remove from it all lateral distortion or buckling; the sinks u being made enough
longer than the frog-form dies to permit the movement of the latter within the sinks,
in the direction of the intervals of increased speed.
The letters T designate the pivoted bending levers which are illustrated in the
general view of the machine at figuro 2 and in enlarged detail at figures 14, 15, LG
and 17. These bending levers are arranged to be over the top of the die-wheel D¹,
and so as to pass around the ends of the sink-roller. They are each pivoted at
to an off-set is projected from the machine frame. The outer ends of each of

page_text: these lovers approach each other at an angle, and their inner ends e, e, back of
where pivoted are curved inwardly towards each other and the adjacent end face
of the sink-roller, whereat each of the said inner ends of each of the levers are
constructed with a friction roller as indicated by the dotted line mo.
The letters to designate a spring arm projected from each of these levers T¹ at their
inner ends and the letter A, a spring arranged intermediately to, and connecting with
each of said spring arms. These bending levers at the front ends are arranged with
reference to the die-wheel so that as the latter revolves towards the outer ends of the
levers, one of the latter, where constructed with bending rollers t, will engage with
the adjacent side of each passing frog-form die, or with a shoe blank that has been.
passed in between the said die (while moving) so as to abut against the blank stop w²,
by which engagement between the bending rollers of the levers the blank will by the
latter be carried around the sides and rounded end of the die, and closed in against
the heel ends of the latter.
The letters K² designate a cam formed upon each of the opposite end faces of the
sink-roller, and each of which cams are constructed to simultaneously engage with
one of the inner ends e of the levers back of where pivoted and where each of them
is provided with a friction roller m³. As the inner ends e of the bending levers T
are spread apart by the action of the cam K2, the front ends of the bending levers
where arranged to engage with the shoe blank are forced towards each other and to
thus bend the blank around the sides of that one of the frog-form dies upon which the
blank is being shaped. After one shoe has been thus bent and shaped, the die on
which it is held passes it to be operated upon by the sink-roller and its sink rim-
plate as before described, and the bending rollers open out again to operate upon
another entered blank in connection with a succeeding frog-form die, brought into
position by the rotation of the die-wheel.
The lettor B designates the bed-plate, which is continued throughout and under
the several mechanisms. This bed-plate is made with a grooved track T* at each side,
extending throughout its length. This track is shown in a plan view in part at
figure 14, and in cross-section at figures 13 and 18. This track has an arbored top
and it is provided as indicated at w figure 3 with sections where the arbor roof is cut out
to enter a bolt head, and where the bolts and nuts have been removed for illustration.
Each of the several mechanisms performing the functions of entering the bar,
creasing it, rough-punching it, full-punching it, and the cutting mechanism, are
provided with feet, that spread out laterally as supports at each side to rest upon
this track T, and as shown in section at figures 4, 5, 12, 13 and 18. The letters 68, at
figure 18 designate bolts adapted to be entered in said track at any of the open
sections w, and therefrom moved along and passed up through the feet f, of the
several mechanisms, and to be there secured by a nut to anchor the parts of the
machine which perform the several and specific functions of working the bar; so
that upon this track T, the full-punching mechanism and the cutting mechanism
may be adjusted to the proper distance from each other, or from the rolls.
The letter T designates a supplemental bed-plate arranged to support the entering
rolls, the creasing rolls and the rough-punching rolls; and this supplemental bed-
plate is adapted by means of side flanges at its base to connect with the bed-plate B₁
and track T by means of bolts as before described for doing the same with the other
mechanism. This supplemental bed-plate is shown in section at figure 18, and it is
constructed also with an arbored and grooved track T, that is adapted to adjustably
connect the rolls-table M² by means of bolts 2', the heads of which are, entered in the
grooved and arbored track of the supplemental bed-plate with the shanks of the bolts
passed up through the top of the track from out of the groove thereof, and also
through the edge of the rolls-table, and to be thereat secured by a nut n¹º.
The letter Y, designates a hand-wheel having a shaft y, that is threaded into a
standard y, on the bed-plate proper B, and also into the leg ys, on the supplemental
bed-plate T. When the bolts which secure the downwardly and outwardly flanged
feet of the supplemental bed-plate to the bed-plate proper are loosened by turning the
R

page_text: hand-wheel the said supplemental bed-plate and the sets of rolls that it supports may
be moved towards, or from the full-punching mechanism.
The letters, designate lugs projected from the sides of the housings of the creasing
rolls at their base, and the letters v³, designate set-screws made to thread into said
lugs, so as to be parallel to the sides of the housings, upon the outer ends of their
rectangular heads by which they are turned, and made to abut against a projection »,
on the housing of the adjacent set of rolls for a close adjustment of the housings as to
distance apart, when being moved for the latter purpose in the arbored track as before
described, and as shown at figures 1, 2, 3, and 18.
The letter, designates a forked plate that is upwardly projected from the bed-
plate, and arranged to intersect the circular line of the traverse made by the frog-form
dies of the die-wheel at each of their sides, and engage with the bent shoes held thereon
to remove them, as shown at figures 1, 2 and 12.
The several bevelled gears upon the shaft S2, from which the several mechanisms
receive power, are all feathered on to the said shaft as shown at f, of figure 3, so that
they may be adjusted thercon to meet the adjustment of the bevelled gears in connection
with which they communicate power to the several sets of rolls, the full-punching
mechanism and the cutting mechanism; and the die-wheel D¹, is made with a
removable die-plate d", by which dies of differing size may be applied thereto.
The combined operation of the several mechanisms thus described and shown is as
follows: A beated bar Y¹ being entered in the direction of the arrow shown at
figure 2, so that its entered end will be caught between the engaging segments of the
shaping rolls at the point where their rotation contact commences; and as these
segments are engaging with the bar it will thereat be operated upon by said rolls and
moved progressively, until the non-engaging segments of the entering rolls meet,
when the progressive movement of the bar ceases. After the entering rolls have in
sequence engaged with another blank length of the bar its entering end will have reached
the creasing rolls, which operate to crease, and move it a blank length progressively.
After the entering end of the bar has passed the creasing rolls it is rough-punched while
the creasing rolls and the entering rolls are operating upon succeeding blank lengths,
when the bar reaches the full-punching mechanism, and while at rest, that blank length
of it which is above the punches is full-punched as before described, and then pro-
gressed by the action of the several rolls to pass in under the guide-plate w, and to
abut against the stop w², and as thus placed between one of the frog-form dies, and
the bending levers it is cut off by the cutting mechanism at a proper length for a
shoe, to be then bent by said levers; flattened by the rim-plates of the sink roller,
and when reaching the forked plate to be removed from the die, the same
operation being continued as bar after bar follows with intermittent periods of
motion and rest.
As the operation of rolls constructed and arranged to give to an entered and heated
bar regular periods of progressive movement and alternating periods of rest would be
the same, whether the full-punching, cutting and bending mechanisms used, was that
shown or some other which would perform the same function; hence I do not limit
my invention of the rolls as constructed to so operate upon the bar with periods of
progressive movement and periods of rest, to their combination with the full-punching,
cutting and bending mechanisms which I'illustrate and describe.
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 1
