IMPROVE- MENTS IN MACHINERY FOR MAKING NAILS
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BERNARD
PEARD WALKER, of North Street, Wolverhampton, Clerk, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Sixth day of March, in the seventh year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Bernard Peard Walker, Her especial licence, full power, sole privilege and
authority, that I, the said Bernard Peard Walker, my exors, admors, and
assigns, or such others as I, the said Bernard Peard Walker, my exors,
admors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVE-
MENTS IN MACHINERY FOR MAKING NAILS;" in which said Letters Patent is
contained a proviso, that I, the said Bernard Peard Walker, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, to be inrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Bernard Peard Walker, do hereby declare that the nature of my said Inven-
tion, and the manner in which the same is to be performed, are fully described

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view, in section, of a machine having my improve-
ments applied thereto, some of the parts being in section; Figure 2 shows a
plan of some of the parts; and Figure 3, an end view of some of the parts.
The other views on the same Drawing show separate parts of the machinery,
in order that their construction may be better understood. a is the main or
driving shaft, which receives motion from a steam engine or other power.
On the shaft a is formed a crank, which, by the connecting rod c, gives motion
to cutter d,, as will readily be understood on examining the Drawing. e is the
fixed cutter. These parts are similar. to those. ordinarily in use for cutting
nails from strips or narrow plates of iron. f is a cam on the axis or shaft a.
This cam, gives, motion to the lever. g, as is shown, and to the lower end of the
lever g is attached the, connecting rod h, which at its other end is attached to
the arm of the toothed sector j; this toothed sector takes into and drives
the bevilled toothed wheel k, and causes it to move half way round, first in one
direction then in the other, by. means of which the strip or. narrow plate of
iron from which the nails to. be. cut is turned over; and as the axis of the
narrow strip of metal is placed at an angle. to the edge of the cutters, pointed
or angular nails are produced, the points being formed first from one edge of
the strip of metal and then from the other, as is well understood. The toothed
wheel is affixed on the tube 7, .which turns in proper bearings at the ends
thereof. m is a rod, which slides freely through. the tube 1, but turns there-
with, owing to there being a longitudinal groove formed in the rod m, into
which a stud or pin enters, which is affixed through the tube 1, as is well
understood; n. is a carriage, sliding freely on the angular bar o, the end of the
rod m turning in bearings .at ...and to the rod.m.is. attached. an universal
joint p, which connects, the rod m with the rod and, holder.m', as is shown, the
holder consisting of two plates drawn together.by a screw and nut, or it may
be by any other convenient means. The two plates of the holder securely
holding the strip or narrow plate of metal q, as is shown, the rod m¹ turns and
moves in a slit bearing at 13, by means of which and the universal joint the

page_text: rod m' and holder may rise in the act of turning, which is an important move-
ment to be communicated to the holder, in order that the same in making a
half revolution may readily turn over the strip or. narrow plate of iron after
each cut has been made. r is a weight, constantly drawing forward the car-
riage and rod m, and consequently the strip or narrow plate of iron; or this
movement of the bar m, and ther parts, up towards the cutters, may be other-
wise obtained. s is the guide through which the narrow strip is fed up to
the cutters, the opening through which allows the strip or narrow plate to be
turned over, but does not allow it to be raised up when in a horizontal position.
The peculiar character of this. machine consists, first, in giving to the
holder the power of rising when turning the strip of iron; and I would state
that I do not confine myself to the mode of allowing or causing the same to
rise together with the end of the metal, as the same may be varied. And,
secondly, in attaching the narrow strip or plate of metal to a holder, con-
nected with a rod or bar, for the purpose of turning over and carrying up the
strip of metal to the cutters. And although I have only shown the apparatus.
applied to one description of nail machine, it will be evident that it may
readily be adapted to other descriptions of nail-cutting machinery where the
turning over the strips of metal from which the nails are to be cut is required..
t is a spring to the carriage, pressing against the under side of the angular bar,
as is shown.
Figure 4 shows the side view, partly in section, of another machine,
wherein the rod m is caused to rise, by the working of the machinery when
turning over the strip or narrow plate of metal, in place of simply allowing
it to rise; Figure 5 is part of a plan thereof; and Figure 6 is an end view
of some of the parts, the other Figures shewing some of the details of this
machine separately. Those parts which are similar to the parts already
described are marked with the same letters of reference, and will not therefore
require further description. In this machine, in place of using the toothed
sector for giving motion to, the tube, through which the rod m. moves, a rack
is employed, which is caused to rise up and down by the rotation of the main
shaft or axis a, as will readily be traced in the Drawing. On the tube / are
affixed two excentrics v, v, which move between fixed surfaces w, w, and thus,
as the tube turns, the tube and rod m, with the holder m', rise and lift the
strip or narrow plate of metal when in the act of turning over that strip or
plate of metal, the tube / moving in sliding bearings in the framing, and the
rod m in a sliding bearing in the carriage n. The stem m¹ of the holder
enters into the rod m, and there is an excentric v₁ affixed on the same, moving
between the two fixed surfaces w³, w¹; hence, when the tube / rises the holder

page_text: rises; and the above alterations, and the alteration in the sliding carriage of
the rod m, as shown, constitute the differences between this machine and that
before described. But the peculiar character of that machine, videlicet, the
causing of the holder and the strip or plate of metal to rise in the act of
turning, and the connecting the strip of metal with a holder and bar are
retained in this machine, though accomplished by slightly different means.
Having thus described the nature of my Invention, and the best means I am
acquainted with for performing the same, I would have it understood that I do
not claim any of the mechanical parts separately, nor do I confine myself to
the precise details shewn, so long as the peculiar character of the Invention
be retained. But what I claim is, the mode herein described of combining
machinery for making cut, nails, whereby the holder of the strip or narrow
plate of metal is caused to rise in the act of turning over the metal. And I
also claim the attaching the strip of metal to be cut to an advancing holder
and bar.
In witness whereof, I, the said Bernard Peard Walker, have hereunto
set my hand and seal, this Fifth day of September, in the year of our
Lord One thousand eight hundred and forty-four.
