Year: 1862

page_text: LETTERS PATENT to James Barclay, of Gravel Lane, Southwark, in the
County of Surrey, Engineer, for the Invention of "IMPROVED MACHINERY
FOR THE MANUFACTURE OF NAILS."
Sealed the 13th February 1863, and dated the 15th August 1862.
PROVISIONAL SPECIFICATION left by the said James Barclay at the
Office of the Commissioners of Patents, with his Petition, on the
15th August 1862.
I, JAMES BARCLAY, of Gravel Lane, Southwark, in the County of Surrey.
Engineer, do hereby declare the nature of the said Invention for "IMPROVED
MACHINERY FOR THE MANUFACTURE OF NAILS," to be as follows:-
This Invention consists of improved machinery for the manufacture of nails
from copper, wrought iron, zinc, or other ductile metal or compound of metals,
either in the form of wire or sheet metal, and the features of novelty in the
present improved machinery consist,-
First, in the mode of heading and pointing nails made from said wire.
And, secondly, in the mode of cutting off short pointed strips the length
of the nail from sheets of metal, and in the use of pressure rollers for con-
solidating said short strips and making same into nails.
To manufacture nails from wire I employ four levers, two working hori-
zontally and two vertically; the ends of each pair of levers operate so as to
squeeze the wire to a point, and are operated upon by slides and rollers. The
67...מr

page_text: heading operation is performed by a sliding heading tool; a revolving plate
fitted with spring sliding holders takes the pieces of wire from the pointing
levers aforesaid, and carries them successively opposite to a heading tool.
Expanding dies, operated upon by a screw for opening and closing same, are
employed to hold the wire whilst it is advanced and cut off to the desired
length to form a nail. I also propose to employ a circular piece of metal or
table suitably held, and capable of being moved about its axis of motion, so
that, supposing a strip of sheet metal of the width of the required length of
the nails to be made therefrom to be placed on said table, and said table to be
moved about its axis of motion by suitable self-acting mechanism, the said
strip instead of being presented square to the cutters is inclined thereto side-
ways, and then cut; the strip is afterwards moved in an opposite direction, and
again cut, the effect of which is to cut strips of a wedge form instead of with
parallel sides, or, in other words, to cut the strips pointed. The heading
operation is effected by a bent lever operated upon by a cam, each nail being
held by expanding dies operated upon by sliding pieces of metal formed
with inclined or wedge-shaped ends. Each strip of metal cut off the
main strip falls upon a vibrating piece of metal formed with two sides, which
throws the cut pieces alternately down two channels formed in a casting;
thence they pass between the pressure rollers before referred to, where they
get consolidated, and, finally, are taken hold of by the expanding dies, and
held thereby during the heading operation.
The above machinery is designed to be double-acting, that is to say, whilst
one nail is being headed on one side of the machine the other side of the
machine is discharging a finished nail.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Barclay in the Great Seal Patent Office on the
14th February 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BARCLAY, of Gravel Lane, Southwark, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of August, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said James Barclay, Her special licence that I, the said James

page_text: Barclay, my executors, administrators, and assigns, or such others as I, the
said James Barclay, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVED
MACHINERY FOR THE MANUFACTURE OF NAILS," upon the condition (amongst
others), that I, the said James Barclay, my executors or administrators, by
an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Barclay, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :--
This Invention consists of improved machinery for the manufacture of nails
from copper, wrought iron, zinc, or other ductile metal or compounds of metals,
cither in the form of wire or sheet metal, and the features of novelty in the
present improved machinery consist,-
First, in the mode of heading and pointing nails made from said wire.
And, secondly, in the mode of cutting off short pointed strips the length of
the nail from sheets of metal, and in the use of pressure rollers for con-
solidating said short strips and making same into nails.
To manufacture nails from wire I employ four levers, two working hori-
zontally and two vertically; the end of each pair of levers operate so as to
squeeze the wire to a point, and are operated upon by slides and rollers. The
heading operation is performed by a sliding heading tool; a revolving plate
fitted with spring sliding holders takes the pieces of wire from the heading
tool, and carries them successively opposite to the pointing tool. Expanding
dies, operated upon by a screw for opening and closing same, are employed to
hold the wire whilst it is advanced and cut off to the desired length to form a
nail. I also propose to employ a circular piece of metal or table suitably held,
and capable of being moved about its axis of motion, so that, supposing a strip
of sheet metal of the width of the required length of the nails to be made
therefrom to be placed on said table, and said table to be moved about its axis
of motion by suitably self-acting mechanism, the said strip instead of being
presented square to the cutters is inclined thereto sideways, and then cut; the

page_text: strip is afterwards moved in an opposite direction, and again cut, the effect of
which is to cut strips of a wedge form instead of with parallel sides, or, in
other words, to cut the strips pointed. The heading operation is effected by a
bent lever operated upon by a cam, each nail being held by expanding dics
operated upon by sliding pieces of metal formed with inclined or wedge-shaped
ends. Each strip of metal cut off the main strip falls upon a vibrating piece
of metal formed with two sides, which throws the cut pieces alternately down
two channels formed in a casting; thence they pass between the pressure
rollers before referred to, where they get consolidated, and, finally, are
taken hold of by the expanding dies, and held thereby during the heading
operation.
The above machinery is designed to be double-acting, that is to say, whilst
one nail is being headed on one side of the machine the other side of the
machine is discharging a finished nail.
And in order to explain my said Invention as completely as possible, I now.
proceed to describe the best means I am acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheets of
Drawings hereunto annexed, and to the numeral figures and letters of reference
marked thereon respectively, as follows;-
DESCRIPTION OF THE DRAWINGS.
At Sheet 1, Figure 1, is a top plan view of some of the principal parts of
my improved machinery for manufacturing nails from wire; Figure 2, a
vertical section through the line A, B, at Figure 1; Figure 3, an elevation of
parts herein-after particularly described and referred to; Figures 4, 5, 6, 7,
respectively exhibit vertical sections taken through the lines, C, D, E, F, G,
H, I, K; Figures 8 to 15 inclusive exhibit detached parts of my improved
machinery.
At Sheet 2, Figure 1 is a top plan view of my improved machinery for
manufacturing nails from metal plates; Figure 2, a vertical section through
the line A, B, at Figure 1; Figure 3, a transverse and vertical section through
the line C, D, at Figure 1; Figure 4, a top plan view of the mechanism
which I employ to hold the nails whilst they are being headed; Figures 5 to 9
inclusive exhibit detached parts of my improved machinery, Figures 5 and 6
of which are represented drawn full size. At each of the foregoing Figures
of each of the Sheets of Drawings I employ similar letters of reference to
denote corresponding parts in so far as such parts appear or can be seen at
each of such said Figures and Sheets of Drawings respectively.
The following is the construction of the machinery I employ in and for the

page_text: manufacture of nails from wire according to my said Invention. At Figures 1
and 2 of Sheet 1, A is a framing supporting the following parts, which are
arranged combined together and actuated as follows: B is the main driving
shaft on which are fixed the fly wheel C and spur pinion D; this pinion gears
into a spur wheel E fixed on the auxiliary shaft G; this shaft, as also the
shaft B, are each formed cranked, and the pins of said cranked parts are
respectively connected by the rods a, b, to sliding rods H, I, working in
suitable guide pieces fixed to the framing A. The rod H carries a tool for
heading the nails, and the rod 1 is connected with a piece of mechanism for
pointing the nails after they have been headed. c is a cam fixed on the
shaft G; the cam c is employed to push forward by means of the sliding
rod d, and hold the nails whilst they are being pointed, as presently described.
K is a revolving shaft, mounted midway between the centre line of the
rod H and the heading tool 1 and the centre of the point 2 of the rod d,
the three centres being in a straight line; e is a casting, at one side of which
is formed a toothed sector 3, and the other side of said casting carries a
pawl 4, which takes into a ratchet wheel 5; this ratchet wheel is fixed on the
shaft G, but the casting e is placed loosely on said shaft; 6, 6, are collars for
keeping the parts e and 5 in proper position on the shaft G; L is a rack, the
teeth whereof gear into the sector 3, as at Figure 9; the rack L works
through guide pieces 7 suitably fixed to the framing A. M is a lever mounted
on a pin 8, which is the fulcrum thereof; the other end of this lever is con-
nected to the rack L. as at Figure 6, and the said lever is operated upon by
the groove 9 of the cam A³, in which fits a pin 10 fixed in the lever M.
I now proceed to describe the construction of the tool exhibited at Figure 8,
which I employ for transferring the nails from the heading tool to the pointing
tools. N is a casting formed with five arms, each of which is furnished with
a sliding piece of steel f, which is kept forced outwards by a spring g; the
upper end of each of the pieces is formed bevilled, as exhibited, and with a
notch therein to receive the nail. are bent pieces fixed to the arms of the
piece N; these bent pieces prevent the pieces from being forced out of their
guides, and also hold the nail in the notch of the pieces /. The casting N is
fixed on the end of the shaft G by screws i, i, and should be so fixed and
adjusted on said shaft as that one of the arms of said casting is opposite to
the centre of the pointing tools, whilst the heading tool is passing between the
two opposite arms to form the head of a nail. The nails when pointed may be
withdrawn from the pointing tools and casting N by the following means:-
kis a bracket piece fixed to the cross framing A'; the construction of the
piece k will be better understood by reference to Figure 10, where I marks a

page_text: stud fixed in the piece k; m, a piece of metal working on a screw at n; o, a
spring for keeping the point of the piece m always forced upwards; p is a
stud fixed in the under side of the rod d; q, a lever hinged thereto; r, a pin
fixed in the side of said lever; the point of this lever is formed with prongs
for the purpose of withdrawing the nails from the casting N. The following is
the action of the above-described withdrawing mechanism:-As the rod d is
pushed forward the pin r in the lever q will be pushed under the stud 1,
thereby allowing the prongs of said lever to pass clear of the head of the nail,
and when the pin r has passed the stud the piece m will spring up, and as the
rod d is drawn back by the pin r will be pulled over the top of the stud 1,
and thus the prongs of the lever will be lifted behind the head of the nail,
and as the rod continues to be drawn back the lever q moving therewith will
withdraw the nail from the pointing tools and casting N. O is a cam fixed
on the shaft G. The cam O is employed to. actuate a lever P, shewn at
Figure 2, said lever having its fulcrum upon a pin 11 fixed to the framing A.
The short end of the lever P as it is raised forces up the piece B¹, carrying the
dies, so as to cut off a piece of wire of the desired length to form the nail;
the piece B' (which works between the guides 12 at Figure 1) afterwards
descends by its gravity until the divided parts of the wire come opposite to
each other.
I will now proceed to describe the mechanism employed for feeding into the
machine the wire from which nails are to be formed, and the manner of
holding said wire firmly whilst the heading operation is being performed.
Q, R, are cams fixed on the shaft G; these cams are employed to operate the
rods S, T, said rods having slots formed therein, in which are fitted rollers 13,
against which the cams Q, R, press alternately for advancing and drawing back
said rods. The rod S has a toothed rack formed at the under side of one end
thereof, which gears into the teeth of a pinions, fixed on the left-handed screw t;
this screw is supported at one end by passing through a hole in the piece u,
which is fixed to and moves with the plate W, and at the other end by a hole
formed in one half of a pair of pinching dies U, against which the point of
said screw presses for closing said dies; the other half of said dies is held by
pieces 14, fixed to the sliding plate W, which said plate works between guide
pieces 15, fixed to the framing A, as at Figure 1. 16 is a piece of metal fixed
by a screw bolt to the under part of the cross framing A', as at Figure 4; X
is a weighted lever for holding the wire of which the nails are to be formed
steady whilst the dies U are being moved back; 17 is a slot in the plate W,
through which the piece 16 passes; 18 is a stud fixed in the plate W, and 19 is
another stud moveable in a groove 20 in the plate, as at Figure 2; 21 is a

page_text: screw fixed by one end in the piece u; the other end of this screw passes into
a plain hole formed in the piece 19. 22 is a band wheel, the top whereof has
a screwed hole therein which fits over the screw 21; by turning said hand
wheel either to the right hand or to the left in like manner the stud 19 will
be pushed closer to the stud 18, or drawn away therefrom. The rod T is
formed with an arm which takes between the studs 18 and 19 for pushing the
plate W backward and forward. 23 is a set screw adjusted in accordance
with the throw of the cam R, to limit the distance which the plate W is
pushed outwards; Y is a coil of square wire, from which the nails are to be
made.
I now proceed to describe the construction and action of the pointing
mechanism exhibited at Figures 11, 12, 13, 14, 15. Z is a casting formed
with a square pin 24 and lugs 25, as at Figure 14; each pair of lugs has a
pin 26 passed through same, which carries a lever of peculiar shape. Two of
these levers, marked 27 at Figure 11, of similar shape, are mounted horizon-
tally in the casting Z opposite to each other, and two other levers of another
shape, marked 28, are mounted vertically in the casting Z. 29 are four sliding
pieces of metal, each having a die 30 screwed thereto; 31 are holes made in
the pieces 29 to receive the short end of the levers 27 and 28, as at Figures 11
and 12; 32 is a casting fitting loosely upon the square pin 24; this casting is
formed with web pieces 33, to which are affixed pins carrying rollers 34; each
pair of rollers embrace the long arm of the levers 27, 28; the casting 32 thus
fitted is connected by the rods 35 to the sliding bar I, which works in suitable
guides, said bar being operated upon by the crank of the shaft B, to which it
is connected by the rod a, and supposing that the dies 30 and levers 27, 28,
to be in the position exhibited at Figures 12 and 13, one pair of dies will be
separated and the other pair closed, and in the act of pointing a nail; the opening
and closing of the said dies is effected by the piece 32 being slided to and fro
upon the square pin 24 of the casting Z. The piece 32, when moved in the
direction denoted by the arrow's flight at Figure 3, will close the vertical dies
and open the horizontal dies, and vice versa when the piece 32 is moved in an
opposite direction; this alternate opening and closing of the pointing dies is
necessary to disengage the pointed nail and to receive another nail to be
pointed.
The operations of the above-described improved machinery are as follows:-
Supposing the several parts to be in the relative positions exhibited by the
Drawing, the operator first passes the wire Y between the dies U and about
one-eighth of an inch through the dies B'; the machine is then set in motion,
and the operations thereof performed in the following order of succession:-

page_text: The lever P lifts the piece B' which divides the wire, the piece B' then
descends, and the heading tool I forms the head of the nail; this donc, the
dies U open, and the plate W with the parts affixed thereto are slided out-
wards by the arm T¹ of the rod T; the dies U are then caused to pinch the
wire tightly by the action of the rod s on the screw t, immediately after which
the plate W is moved in an opposite direction, and the dies U moving there-
with draw the wire under the weighted lever X, and in so doing the wire
pushes the partly-formed nail just headed out of the dies, and simultaneously
with this action the casting N is caused to move and take hold of the discharged
partly-formed nail and carry it out of the way of the heading tool, which again
comes into action and forms a hend upon the next piece of wire in the dies
after said wire has been cut, as before described. The casting N then operates
again as above stated, and when one of the headed pieces of wire are brought
opposite to the pointing dies 30, the point 2 of the rod d forces the wire
between the pointing dies, and holds it there whilst it is being pointed; the
rod d then retires, and the nail is drawn out by the means before described.
and in this manner and by these means the operations are successively carried
on. I would here remark that according to the length of nail required in like
manner the stud 19 is adjusted by the wheel 22, that is to say, if a short nail
is required, then the stud 19 should be moved away from the stud 18, by
which the wire will be moved a shorter distance, the dies at B¹ being made
accordingly; to make a long nail, the studs 18 and 19 should be as close
together as possible; and I would observe, that this mode of adjustment is
an important novelty in machinery for making nails from wire. I would here
remark, that for the sake of economy, I make the dies in B¹ square, as at
Figure 7, and on each edge I form a notch suited to take wire of different
sizes. And whereas in practice I have found the casting N liable to overrun
itself, to prevent this friction must be applied to the axle thereof either by a
leather strap with a weight affixed thereto, or any other suitable means.
I now proceed to describe the improved machinery exhibited at Sheet 2,
adapted for manufacturing nails from sheet metal.
A, A, represents the framing of the machinery supporting the following
parts, which are arranged combined together and actuated as follows:- B, the
main driving shaft, on which is fixed the driving pulley C, the wheel D, cams
E, G, and H, and spur wheel L; K is an ordinary sliding clutch box for
starting and stopping the working parts of the machinery by means of the
lever L. a, a, are strong brackets fixed to the framing' A; these brackets
support the axis of the pinion M, which gears into the teeth of the wheel I,
and also the axis N, on which is fixed the lever O; one end of this lever takes

page_text: an opposite end of said lever is furnished with antifriction rollers b, c, which
are respectively acted upon by the parts 1, 2, of the cam H; the part 1 serves
to raise this end of the lever, and the part 2 to depress same. The plate P
has a cutter d affixed thereto, whose edge is adjusted flush with another
cutter e securely fixed in the plate : this plate with the piece carrying the
adjustable guide pieces g. is formed of one solid piece of metal, the edge of the
plate is turned circular and bevilled, and fits easily in a corresponding shaped
hole formed in the plate Q. which is firmly fixed to the framing A; the plate f
and piece fare also formed with an arm R in the slots 3, whereof one end of
a rod s is adjusted, the opposite ends of said rod being adjusted and fixed in
the slot of another rod T carrying rollers h, h, at one side thereof. The rod T
is supported by and works in guide pieces or brackets i, i, fixed to the
framing A; the cam G. operating upon the rollers h. h, imparts alternate
reciprocating motion to the rod T, and caused the plate f and parts affixed
thereto to move in an alternate circular direction within the plate O for the
purpose herein-after described. U, U. are castings securely fixed to the
framing A, these castings embrace another casting k, which is capable of
being slided in the castings U. U, by the lever handle W; 1 is a hopper-
shaped piece of metal connected to the piece by a pin m fitting in a hole
in k; n is a spring for forcing the piece outwards; X is a weight for pulling
forward the piece k after said piece has been pulled back; o is an oblong
shaped hollow piece of metal, shewn detached at Figure 5, drawn to an
enlarged scale; Y, Y, are steel rollers respectively fixed upon shafts or
spindles p, q; the shaft p has a spur wheel r fixed thereon which gears into
the pinion M, and is driven thereby.
The rollers Y are each formed with
recesses 4 about their peripheries, as seen at Figures 3 and 6, and are so
adjusted and fixed on their axes p, q, as to come opposite to the channels 5, 5,
in the piece o, as at Figure 5; the rollers Y are geared together by pinions,
to ensure the recesses 4 therein coming opposite to each other as the rollers
rotate. s is a forked rocking lever mounted on a pin 6 fixed across the piece o;
tis another rocking lever mounted on another pin at 7, also fixed across the
piece o; the upper part of the piece t is formed with two rectangular shaped
surfaces 8, 8, of the width of the piece o, in which it should move freely, but
the length of each of the surfaces 8, 8, is shorter than the opening in the
piece o, as exhibited; u is a rod with a pin therein at g, said pin taking into
the lowest forked end of the lever s; the rod u, which should be suitably
supported, is connected to the lever W, whose fulcrum is a pin 10 suitably
fixed; the opposite end of the lever W carries a small roller which fits easily
in the groove 11 of the cam E. The rollers Y work in water in a double

page_text: trough 12 fixed across the framing A; openings are made through said trough for
the passage of the partly formed nails; 13 mark two pairs of dies, see Figure 4;
the parts of these dics are fixed and the other parts are moveable in suitable
guides; 14 are springs for opening or separating said dies to receive the nails
which they are intended to hold whilst they are being headed. The dies 13
should be so adjusted and fixed so as to be opposite to the recesses 4 in the
rollers Y.
I now proceed to describe the mechanism employed for heading nails
according to this Invention. At Figure 4, 15 are two bent levers, one of
which is exhibited at Figure 2; these levers are mounted upon an axis x, the
short arm of each of the levers 15 has a notch made therein of the desired
shape for the head of the nail, and the long end of each of said levers is
furnished with an antifriction roller, which is acted upon respectively by the
cams 16; these cams are fixed on a shaft y, on which is also fixed a spur
wheel 17 gearing into the spur wheel I, by which rotatory motion is imparted
to the cams 16. 18 are other cams, also fixed on the shaft y; these cams are
respectively embraced by rollers z attached to the flat rods 19, these rods work
in suitable guide holes in the cross framing A¹, and one end of said holes is
formed bevilled; the edge of each of the moveable dies 13 is also formed of
the same bevil, so that as the cams 18 rotate, the rods 19 will alternately and
simultaneously close one pair of dies and open the other pair of dies, as
exhibited, and vice versa, the springs 14 pulling open the dies as the rods 19
are drawn back.
I now proceed to describe the mode of operating with the above-mentioned
improved machinery for manufacturing nails from sheet metal.
MODE OF OPERATING.
Suppose wrought iron to be employed, the sheet metal should first be cut
into strips of the width of the intended length of the nail; these strips are
then cut into short lengths, say about two inches long; these pieces are then
made red hot, and one of such lengths is placed by the operator on the hopper
plate ; the handle W is then drawn back to allow the strip of metal to fall
flat on the cutting die e; this done, the handle is released, by which the
weight x will move forward the piece k until the end of the pusher plate z
comes into close contact with the end of the strip of metal, said strip being
thus forcibly pressed against one or other of the bevilled edges of a plate z fixed
to the bottom of the cutter d, as at Figure 10. The machinery is then set in
motion, and the operations performed in the following order of succession:-
First, the strip is cut by the action of the cam I on the lever O at an angle, as

page_text: denoted by the Diagram at Figure 7; the cam then moves the plate ƒ partly
round into the position denoted by the dotted lines at Figure 7, and the strip
is again cut at an opposite angle, the weight x by its gravity always pulling
the strip in close contact with the edge of the plate ; by these means a wedge
or pointed shaped piece of metal will have been cut off the aforesaid strip, and
the piece so cut off will be deposited on one or other of the surfaces 8 of the
rocking piece t. The cam E now acts upon the lever and rod W and u, and
moves the piece t on its axis, thereby throwing the cut piece of metal thereon
down one or other of the channels 5 in the piece o; the cut piece falling with
its point upwards is caught by the rollers Y in the recesses 4 thereof, and as
said rollers rotate the metal is consolidated by pressure of said rollers, and as
said rollers continue to rotate the consolidated piece falls out and is caught by
and held between the dies 13, after which the heading lever 15 is forced up
by the cam 16, and the head of the nail thus formed and the nail completed.
These dies now open and discharge the finished nail, and simultaneously with
these operations another strip of metal will have been cut off the main strip
and deposited in the opposite channel 5 to that lastly described, and have been
embraced by the opposite consolidatory rollers, and be headed as before
described, and in this manner and by these means the machinery is continually
working, that is to say, whilst the nails are being formed at either side of the
machine the nails are being discharged at the opposite side of the machine.
Although in this my Specification I have shewn and described machinery for
heading and pointing nails in one machine, I do not intend to limit myself
to the use of a compound machine for the above purposes of heading and
pointing nails, but, when desirable, I propose to make separate machines for the
above purpose, namely, one to form the heads of nails, which are then removed
and placed in another machine to form the points; and when separate machines
are employed, the mechanism contained in the casting N and that employed
for imparting motion to same may be dispensed with, and the pointing machine
be fed by hand.
Having now fully described and set forth the nature and object of my said
Invention of "Improved Machinery for the Manufacture of Nails, together
with the best means I am acquainted with for carrying the same into practical
effect, I would remark, in conclusion, that I hereby declare my Invention to
consist in and I claim the general combination, arrangement, and operations, of
the parts above described with reference to the Sheets of Drawings accom-
panying these Presents.
And especially I claim the parts 19, 20, 21, 22, at Figure 1 of Sheet 1, for
regulating the length of the nails.

page_text: Also the parts marked U 14, s, t, u, S, Q, 13, at Figure 1 of Sheet 1,
for feeding the wire into the machine.
Also the parts marked N, f, g, h, K, L, M, 3, 4, 5, 6, e, 10, A¹, at
Figures 8 and 9 of Sheet 1, for transferring the partly formed nail from the
heading tool to the pointing tools.
And, lastly, the mechanism above described with reference to Figure 10 of
Sheet 1, for drawing out the finished nails from the holder N.
And as regards Sheet 2 of the accompanying Drawings I claim especially
the mechanism above described with reference to said Sheet of Drawings for
cutting off short pointed strips from metal plates; also the rollers marked Y
at Figure 6, for consolidating the pointed strips of metal; also the mechanism
above described with reference to Figure 5, for conducting the aforesaid
pointed strips of metal into the recesses 4 of the rollers.
In witness whereof, I, the said James Barclay, have hereunto set my
hand and seal, this Fourteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-three.
