I, GEORGE HENRY PARKIN, of Marlborough House, Mottram Road, Stalybridge, in
the County of Chester, Engineer, do hereby declare the nature of the said invention,
to be as follows:-
Horse shoe nails are cut from channel bars of metal, and the nails thus cut are
termed "blanks" and the cutting of such blanks is an ordinary and well known
process.
My invention relates to machinery for finishing the cut "blanks" and consists in
combinations and arrangements of mechanism, namely,
There is a vertical shaft or axis in suitable bearings in the framing, and upon
which shaft there is a thin dise or table of metal or there are arms carried by the
vertical shaft, which is rotated intermittently, that is, to make a quarter revolution
and pause four times for each revolution of the vertical shaft.
This intermittent motion is produced by a "star wheel " or other suitable
arrangement driven from a shaft in suitable bearings on the framing making four
revolutions for one of the vertical shaft.
The table or disc on the vertical shaft carries four sets of grippers 90 degrees apart,
each set of grippers consists of a slide pressed inwards by a spring, which slide is
longitudinally in a radial line from the axis of the vertical shaft, and the other two
slides are opposite to each other and at a right angle to the first named slide which
acts to press or grip the nail against one side of the hole in the block carrying the
gripper slides, and this first named slide has a projection from it which is acted upon
by a stationary cam surface, adjustably fixed on the framing, when the grippers are
brought round by the rotation of the vertical shaft, the slide being thus withdrawn
to allow the blank to be pushed vertically between the grippers, which blanks are
fed by hand.
The lower or point end of the blank comes against a table or guage, and before
the end of the blank leaves the guage or table (adjustably secured to the framing) by
the motion from the vertical shaft, the stationary cam will have released the gripper
withdrawn by it, and the blank is then held in the correct position within the
grippers.

page_text: After the blank has been placed within the grippers the first quarter revolution
of the vertical shaft carries its point end opposite an adjustable surface on the
framing, where and against which it is acted upon by another adjustable surface
carried on the lever, having its fulcrum on the framing, which lever is oscillated by
a crank, excentric or cam, and this movement flattens the thick part of the point
end of the blank.
The next move of the vertical shaft carries the point end of the blank opposite
a V die adjustably secured to the framing, then a lever or slide carrying an
adjustable V cutter, cuts the surplus metal away and leaves the point end of the
blank sharp pointed.
The next move of the vertical shaft brings the point end of the blank over an
adjustable pair of rollers having bearings on the framing and geared to make four
revolutions for each revolution of the vertical shaft. These rollers have their surfaces
formed excentric or are so shaped as to roll the blank in passing between them in a
taper form, and the blank is forced down through the grippers (the springs for which
giving way) by a vertical sliding spindle or rod that acts upon the head of the
blank.
This vertical spindle or rod is actuated by a crank, excentric or cam making four
revolutions for each revolution of the vertical shaft.-The rollers deliver the nail
below them finished.-One blank is fed and one nail is delivered finished, at each
quarter revolution of the vertical shaft.

Horse shoe nails are cut from channel bars of metal, and the nails thus cut are
termed "
blanks," and the cutting of such blanks is an ordinary and well known
My invention relates to machinery for finishing the cut "blanks," and consists in
combinations and arrangements of mechanism namely, as hereinafter described and as
pointed out in the claims.
In my improved machine there is a vertical shaft or axis in suitable bearings in the
framing and upon which shaft there is a thin disc or table of metal, or their there
are arms carried by the vertical shaft, which is rotated intermittently, that is, to
make a quarter revolution and pause four times for each revolution of the vertical
shaft.
This intermittent motion is produced by a "star-wheel" or other suitable arrange-
ment driven from a shaft in suitable bearings on the framing making four revolutions
for one of the vertical shaft.
The table or disc on the vertical shaft carries four sets of grippers 90 degrees
apart, each set of grippers consists of a slide pressed inwards by a spring which slide
is longitudinally in a radial line from the axis of the vertical shaft and the two other
we slides are opposite to each other and at a right angles to the first named slide
which acts to press or grip the nail against one side of the hole in the block carrying
the gripper slides, and this first named slide has a projection frem it which is acted
upon by a stationary cam surface adjustably fixed on the framing, when the grippers
are brought round by the rotation of the vertical shaft, the slide being thus withdrawn
to allow the blank to be pushed vertically between the grippers, which The blanks are
fed by hand, and the lower or point end of the each blank comes against a table or guage,
and before the end of the blank leaves the guage or table (adjustably secured to the
framing) by the motion from the vertical shaft, the stationary cam will have released
the gripper withdrawn by it and the blank is then held in the correct position within
the grippers.
After the blank has been placed within the grippers the first quarter revolution of
the vertical shaft carries its point end opposite an adjustable surface on the framing
where and against which it is acted upon by another adjustable surface carried on
lever having its fulcrum on the framing which lever is oscillated by a crank excentric
or cam, and this movement flattens the thick part of the point end of the blank.
The next move of the vertical shaft carries the point end of the blank opposite a
V die adjustably secured to the framing, then a lever or slide carrying an adjustable
V cutter, cuts the surplus netal away and leaves the point end of the blank sharp
pointed.

page_text: The next move of the vertical shaft brings the point end of the blank over an
adjustable pair of rollers having bearings on the framing and geared to make four
revolutions for each revolution of the vertical shaft-These rollers (or one of them)
have their surfaces formed excentric or are so shaped as to roll the blank in passing
between them in a taper form, and the blank is forced down through the grippers (the
springs for which giving way) by a vertical sliding spindle or rod that acts upon the
head of the blank.
This vertical spindle or rod is actuated by a crank excentric, or cam making four
revolutions for each revolution of the vertical shaft.
The rollers deliver the nail below them finished-One blank is fed and one nail is
delivered finished at each quarter revolution of the vertical shaft.

is
In Figs. 1 to 5, a is the framing of the machine, the first motion shaft in
suitable bearings on the framing, the fast and loose belt driving pulleys,
a hand and fly wheel on the opposite end of the shaft b, upon which there is a
spur pinion that gears with a spur wheel fast on the end of the second motion
shaft c which is parallel to the first (b) whieh and, is in suitable bearings on the
framing.
The opposite end of this shaft c has a spur pinion (not shown) under and gearing
with the spur wheel d' on another or third motion shaft d in suitable bearings parallel
to the two first named shafts.
At the end of the shaft d on the right side of the machine there is a disc d secured
having a crank pin d³ upon which there is a block d' that can slide freely to and fro in
a slot in a bent lever e, (see fig. 2) having its fulcrum on a stud e¹ in the side of the
frame of the machine.
The shaft & has also a bevel wheel d³ upon it that gears with one f¹ on a shaft f in
suitable bearings on the framing at a right angle to the shaft d.
This shaft has another bevel wheel upon it that gears with a bevel wheel gon
the upper end of a short vertical shaft having its bearing in a part or bracket
'formed upon or secured to the framing (as shown in figs. 1 and 5).
The lower end of this short vertical shaft g has a pin plate securel to it which at
each revolution imparts a quarter turn to a "star wheel" 9" having four divisions or

page_text: making four quarter turns for each revolution of the pin plate and then pausing
between each revolution-This motion is the well known "star wheel motion -The
star wheel g³ is secured on the lower end of the vertical shaft h in suitable bearings in
the framing, the upper end of which shaft has a boss or disc plate secured upon it,
upon which a thin sheet iron disc or table plate rests-which is secured to the
shaft hand boss disc ¹ by another disc or washer ³ and a screw upon the end
of the vertical shaft; a wood washer, or washer of other suitable material, being
inserted between the metal washer ³ and table plate 2 to check vibration
producing noise.
On the rim part of this thin table plate four sets of grippers or nail blank holders
are secured at 90 degrees of the circle apart but only one set of holders is shown in
dotted line in fig. 1.
The plan view of one of these holders or grippers is shown in dotted line in fig. 1,
and a vertical section through two of them (one on each side of the table ²) is shown
in fig. 5.
The block or frame part of each holder has three arms two in a straight line and one
at a right angle and between the other two. Each arm has a hole in its axis for a
slide to move to and fro in, one end of which is reduced to a bevel point so that all
the points of each slide can come together-Each slide is acted upon by a small
helical spring within the hole in the block the force of which spring is adjusted by a
set screw That slide i the lengthway of which is in a radial line from the shaft his
formed as shown in fig. 5, so that the sliding part can be inserted through a slot in
the top of the block and then the spring and lastly the adjusting set scrow The
upward projection from the radial slide is acted upon by an adjustable stationary
cam surface.
This cam surface is formed upon a plate i³ see Fig. 1 secured to the frame and
coming clear and above the projection the cam surface descending down on the
inside of the projection to draw it outwards and this takes place when the table plate ³
in rotating brings the projection against the stationary cam surface so that when
the table plate 2 remains stationary for a time the slide i is remains drawn back to
allow the nail blank to be inserted with the front flat face of the blank (2) towards
the point of the withdrawn slide the point of the inserted blank being pushed down
until its point end comes against an adjustable guage or table below the rotary table /².
-When the latter begins to make its next movement the cam releases its hold of the
projection from the slide before the point of the nail blank leaves the guage or
table for it, and thus the blank is held by the grippers in its correct position for the
subsequent operations.
The first operation is to flatten the point end of the nail as in 2, Fig. 6.
In the frame of the machine there is a slot or recess to hold a steel block; which
can be adjusted endways by suitable packing inserted between its inner end and the
slot or hole for it in the frame casting-In the vertical face of the framing on one
side there are two set screws j¹ inserted with flat heads so that when the heads are
turned into one position they will pass through slots in the flange of a boss part 2 and
when passed through the flat heads of the screws j' can be turned across the slots as
shown in figs. 1 and 5 and the point of the set screw in the centre of the boss j
can then be screwed to come against the side of the die or block j and secure it in the
slot.
The block may be secured by any other convenient arrangement.
There is a lever e² which oscillates up and down on a fulcrum ex on the framing,
the levere being free to move up and down in a slot or recess formed in the upper
side of the framing.
There is a steel piece on the underside and outer end of the lever e which comes
upon a bowl et on a pivot in a recess in the lever e, so that the up movements of the
latter are thus imparted to the lever e², and the down movements by a helical spring
(not shown) one end of which is attached to the projection or knob e* and the other
end to some convenient part of the framing below the knob.

page_text: On the upper face of the lever a slot is formed in its lengthway for a die e
which is secured in the slot by a set screw e in a part formed on or attached to the lever e².
There is also a recess for a screw nut 8 through which an adjusting set screw e
passes. the point of this set screw coming against the end of the steel die e" and thus
resists the pressure that comes upon it.
The faces of the block j and die which come against and flatten the point end of
the nail blank are inclined to give the required inclined surface to the nail blank
when the lever is in its highest position-After the flattening operation the nail blank
is carried to the cutter which will be explained by referring to figs 1 and 4.
A stationary steel cutter k the edge of which is of the form required, and may be
termed the solid cutter, is secured in a recess in the framing by a boss part set screw k¹
and two flat headed screws as explained in reference to the block for flattening-
and the nail blank when it comes round is brought in front of this stationary solid
cutter.
The Vof the other cutter k² which may be termed the hollow V of the cutter, when
moved towards the solid cutter, passes on each side of the latter and shears away all
metal extending beyond each side of the solid cutter k-The hollow cutter ² is secured
in a recess in a slide by a similar arrangement to that for the solid cutter k.
The slide can move to and fro on a slide-way formed upon or secured to the
framing.
There is a stud in the face of the slide
boss forming one end of an excentric rod
secured upon the shaft d.
upon which a hole in a hoss fits, this
the other end of which fits an excentric k
One flange is fast or solid with the excentric the other is formed by a disc or
washer secured to the excentric by screws.
The nail blank is next carried to come over and between two rollers, each on a
separate shaft in suitable bearings in the framing.
One roller is rotated by a spur wheel 3 fast on the shaft f which gears with a
carrier wheel on a stud (not seen) and this carrier wheel gears with a wheel on the
end of the roller shaft and this wheel gears with the wheel on the shaft for
the roller so that the surfaces of the two rollers and which come opposite, move
in the same direction and draw the nail blank from the grippers.
The roller has or may have a cylindrical surface and has a flange on one side
and one side of the nail blank comes against this flange the periphery of the other
roller is formed with a recess or cavity of the form required to receive the nail blank,
and the bottom of this recess in the roller is excentric to the axis of the roller 15 to
give the required flattening and tapering of the nail blank in.its lengthway.
There is a spring piece secured to the framing as seen in fig. I and in fig. 3, the
free end of the spring having a triangular formed piece to come between the two
rollers and without touching them.
When the nail blank is pushed down between the rollers 11 it passes between the face
of this triangular piece and the flange on the roller l, which triangular piece keeps it
against the flange of the roller l.
=
that gears with
On one end of the excentric roller shaft there is a spur pinion
one 18 on a stud secured in the framing and the boss of this wheel on the stud is
formed into an excentric, giving motion to a rod m the lower part of which is shown
partly in section in fig. 1, and in dotted line in fig. 5, the upper part of the excentric
rod m is shown in full line in the upper part of fig. 5 the upper end being jointed to
a stud m¹ in a slide m² sliding vertically on a slide-way a¹ forined on or attached to the
framing.
This slide m carries a spindle m³ which is adjustable by a set screw m in a
projection formed on the slide-The lower end of this spindle m³ comes directly over
the head of the nail blank when brought round by the intermittently rotating table /*.
The rollers and make one revolution for each nail blank to be operate! upon,
and they are timed and adjusted as well as the pushing spindle m³, to push the nail
blank from the grippers, and the point end to the proper place between the rollers the

page_text: pusher m³ following up the head of the nail blank until the rollers and have secure
hold of it.
The nail passes between the rollers and drops from them below-but as the nail
tends to adhere to the roller a thin steel plate me is secured to the framing or a
bracket secured thereto to come against the periphery of the roller and separate the
nail from it.
To receive guide and straighten the mail, if bent on coming from the rollers, it is
arranged-to pass between-one-side-of a fixed-block-n-secured to the framing and the

Improvements in Machinery for Making Horse Shoe Nails.
I GEORGE HENRY PARKIN of Marlborough House, Mottram Road, Stalybridge in
the County of Chester, Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
[6
Horse shoe nails are cut from channel bars of metal, and the nails thus cut are
termed blanks," and the cutting of such blanks is an ordinary and well known
process.
My invention relates to machinery for finishing the cut "blanks," and consists in
combinations and arrangements of mechanism namely.
There is a vertical shaft or axis in suitable bearings in the framing and upon which
shaft there is a thin disc or table of metal, or their are arms carried by the vertical
shaft, which is rotated intermittently, that is, to make a quarter revolution and pause
four times for each revolution of the vertical shaft.
This intermittent motion is produced by a "star-wheel" or other suitable arrange-
ment driven from a shaft in suitable bearings on the framing making four revolutions
for one of the vertical shaft.
The table or disc on the vertical shaft carries four sets of grippers 90 degrees
apart, each set of grippers consists of a slide pressed inwards by a spring which slide
is longitudinally in a radial line from the axis of the vertical shaft and the other
two slides are opposite to each other and at a right angle to the first named slide
which acts to press or grip the nail against one side of the hole in the block carrying
the gripper slides, and this first named slide has a projection from it which is acted
upon by a stationary cam surface adjustably fixed on the framing, when the grippers
are brought round by the rotation of the vertical shaft, the slide being thus withdrawn
to allow the blank to be pushed vertically between the grippers which blanks are fed
by hand.
The lower or point end of the blank comes against a table or guage, and before the
end of the blank leaves the guage or table (adjustably secured to the framing) by
the motion from the vertical shaft, the stationary cam will have released the gripper
withdrawn by it and the blank is then held in the correct position within the grippers.
After the blank has been placed within the grippers the first quarter revolution of
the vertical shaft carries its point end opposite an adjustable surface on the framing
where and against which it is acted upon by another adjustable surface carried on a
lever having its fulcrum on the framing which lever is oscillated by a crank excentric
or cam, and this movement flattens the thick part of the point end of the blank.
The next move of the vertical shaft carries the point end of the blank opposite a
V die adjustably secured to the framing, then a lever or slide carrying an adjustable
V cutter, cuts the surplus metal away and leaves the point end of the blank sharp
pointed.

page_text: The next move of the vertical shaft brings the point end of the blank over an
adjustable pair of rollers having bearings on the framing and geared to make four
revolutions for each revolution of the vertical shaft-These rollers (or one of them)
have their surfaces formed excentric or are so shaped as to roll the blank in passing
between them in a taper form, and the blank is forced down through the grippers (the
springs for which giving way) by a vertical sliding spindle or rod that acts upon the
head of the blank."
This vertical spindle or rod is actuated by a crank excentric, or cam making four
revolutions for each revolution of the vertical shaft.
The rollers deliver the nail below them finished-One blank is fed and one nail is
delivered finished at each quarter revolution of the vertical shaft.

The plan view of one of these holders or grippers is shown in dotted line in fig. 1,
and a vertical section through two of them (one on each side of the table ³) is shown
in fig. 5.
The block or frame part of each holder has three arms two in a straight line and one
at a right angle and between the other two.-Each arm has a hole in its axis for a
slido to move to and fro in, one end of which is reduced to a bevel point so that all
the points of each slide can come together-Each slide is acted upon by a small
helical spring within the hole in the block the force of which spring is adjusted by a
set screw That slide i the lengthway of which is in a radial line from the shaft h is
formed as shown in fig. 5, so that the sliding part can be inserted through a slot in
the top of the block and then the spring and lastly the adjusting set screw i¹-The
upward projection from the slide is acted upon by an adjustable stationary cam
surface.
This cam surface is formed upon a plate i³ secured to the frame and coming clear
and above the projection 2 the cam surface descending down on the inside of the
projection to draw it outwards and this takes place when the table plate /² in rotating
brings the projection against the stationary cam surface so that when the table
plate remains stationary for a time the slide i is drawn back to allow the nail blank
to be inserted with the front flat face of the blank (2) towards the point of the
withdrawn slide the point of the inserted blank being pushed down until its point
end comes against an adjustable guage or table below the rotary table 2-When the
latter begins to make its next movement the cam releases its hold of the projection 2
from the slide before the point of the nail blank leaves the guage or table for it,
and thus the blank is held by the grippers in its correct position for the subsequent
operations.
The first operation is to flatten the point end of the nail as in ³.
In the frame of the machine there is a slot or recess to hold a steel block j which
can be adjusted endways by suitable packing inserted between its inner end and the
slot or hole for it in the frame casting-In the vertical face of the framing on one
side there are two set screws j¹ inserted with flat heads so that when the heads are
turned into one position they will pass through slots in the flange of a boss part and
when passed through the flat heads of the screws j¹ can be turned across the slots as
shown in figs. 1 and 5 and the point of the set screw in the centre of the boss
can then be screwed to come against the side of the die or block j and secure it in the
slot.
The block may be secured by any other convenient arrangement.
There is a lever e which oscillates up and down on a fulcrum ex on the framing,
the lever being free to move up and down in a slot or recess formed in the upper
side of the framing.
There is a steel piece on the underside and outer end of the lever e² which comes
upon a bowl et on a pivot in a recess in the lever e, so that the up movements of the
latter are thus imparted to the lever e, and the down movements by a helical spring
(not shown) one end of which is attached to the projection or knob es and the other
end to some convenient part of the framing below the knob.
On the upper face of the lever e² a slot is formed in its lengthway for a die e
which is secured in the slot by a set screw e in a part formed on or attached to the lever.

page_text: There is also a recess for a screw nut
through which an adjusting set screw e
passes, the point of this set screw coming against the end of the steel die e and thus
resists the pressure that comes upon it.
The faces of the block j and die e" which come against and flatten the point end of
the nail blank are inclined to give the required inclined surface to the nail blank
when the lever is in its highest position-After the flattening operation the nail blank
is carried to the cutter which will be explained by figs. 1 and 4.
A stationary steel cutter & the edge of which is of the form required, and may be
termed the solid cutter, is secured in a recess in the framing by a boss part set screw k¹
and two flat headed screws as explained in reference to the block for flattening-
and the nail blank when it comes round is brought in front of this stationary solid
cutter.
The Vof the other cutter k² which may be termed the hollow V of the cutter, when
moved towards the solid cutter, passes on each side of the latter and shears away all
metal extending beyond each side of the solid cutter -The hollow cutter 2 is secured
in a recess in a slide 3 by a similar arrangement to that for the solid cutter k.
The slide can move to and fro on a slide-way formed upon or secured to the
framing.
There is a stud in the face of the slide 3 upon which a hole in a boss fits, this
boss forming one end of an excentric rod the other end of which fits an excentric ke
secured upon the shaft d.
One flange is fast or solid with the excentric & the other is formed by a disc or
washer secured to the excentric by screws.
The nail blank is next carried to come over and between two rollers, each on a
separate shaft in suitable bearings in the framing.
One roller is rotated by a spur wheel ³ fast on the shaft f which gears with a
carrier wheel on a stud (not seen) and this carrier wheel gears with a wheel 2 on the
end of the roller shaft and this wheel gears with the wheel on the shaft for the
roller so that the surfaces of the two rollers and which come opposite, move in
the same direction and draw the nail blank from the grippers.
The roller has or may have a cylindrical surface and has a flange on one side and
one side of the blank comes against this flange the periphery of the other rolier 1 is
formed with a recess or cavity of the form required to receive the nail blank, and the
bottom of this recess in the roller is excentric to the axis of the roller to give the
required flattening and tapering of the nail blank in its lengthway.
There is a spring piece secured to the framing as seen in fig. 1 and in fig. 3, the
free end of the spring having a triangular formed piece to come between the two
rollers and without touching them.
When the nail blank is pushed down between the rollers it passes between the face
of this triangular piece and the flange on the roller l, which triangular piece keeps it
against the flange of the roller l.
On one end of the excentric roller shaft there is a spur pinion that gears with
one on a stud secured in the framing and the boss of this wheel 18 on the stud is
formed into an excentric, giving motion to a rod m the lower part of which is shown
partly in section in fig. 1, and in dotted line in fig. 5, the upper part of the excentric
rod m is shown in full line in the upper part of fig. 5 the upper end being jointed to
a stud m¹ in a slide m² sliding vertically on a slide-way a' formed on or attached to the
framing.
This slide m carries a spindle m³ which is adjustable by a set screw m in a
projection formed on the slide-The lower end of this spindle m³ comes directly over
the head of the nail blank when brought round by the intermittently rotating table 2.
The rollers and make one revolution for each nail blank to be operated upon,
and they are timed and adjusted as well as the pushing spindle m³, to push the nail
blank from the grippers, and the point end to the proper place between the rollers the
pusher m³ following up the head of the nail blank until the rollers and have secure
hold of it.
The nail passes between the rollers and drops from them below-but as the nail

page_text: tends to adhere to the roller a thin steel plate m³ is secured to the framing or a
bracket secured thereto to come against the periphery of the roller and separate the
nail from it.
To receive guide and straighten the nail, if bent on coming from the rollers, it is
arranged to pass between one side of a fixed block n secured to the framing and the
bent end of a rod n² shown in figs. 1 and 3 but best in the latter figure, this rod n¹
can slide to and fro in bearings in the framing-One part has a bearing at n² another
at n³ and another at nt.
The lower end of the face of the end slide n¹ coming in contact with the nail has a
horizontal projection n from it that prevents the nail from dropping away until
allowed to do so.
n
The block has a projection from one side against which the side of the operating
bent end of the rod n¹ slides which end of the rod has a slot in it to pass a pin
extending from the projecting side of the block-The nail when delivered by the
rollers and passes into the recess for it formed by the operating end of the slido n
and the two sides of the block n and between the pin n³ and the operating surface of
the block n, this pin n thus acting to prevent the nail from following the slide n' and
thus to push the nail off the projection n when the slide n' is withdrawn.
This slide n is moved to press and straighten the nail by an excentric or cam nⓇ on
the shaft d which cam acts against a vertical stud n' in the stud n'.
When the slide n¹ is moved back by a spring (not shown) the finished nail is allowed
to drop away or into any suitable receptacle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is.
.
1. The combination and arrangement of mechanism for operating upon cut blanks
to form finished horse shoe nails substantially as hereinbefore described and illustrated
by the drawings.
2. The arrangement of holders or grippers on a rotary table so that the blank nails
can be fed and carried in succession to flattening, cutting and rolling mechanism
substantially as herein before described and illustrated by the drawings.
