APPARATUS FOR MAKING PLAIN TWISTED NAILS, SPIRAL FLUTED NAILS, AND
OTHER SIMILAR DRIVING ARTICLES OF A TWISTED OR SPIRAL FLUTED FORM
THROUGHOUT OR IN PART."
Sealed the 4th February 1862, and dated the 10th August 1861.
PROVISIONAL SPECIFICATION left by the said Montague Wigzell
at the Office of the Commissioners of Patents, with his Petition, on
the 10th August 1861.
I, MONTAGUE WIGZELL, of Friar's Green, Exeter, in the County of Devon,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR MAKING PLAIN TWISTED NAILS, SPIRAL FLUTED
NAILS, AND OTHER SIMILAR DRIVING ARTICLES OF A TWISTED OR SPIRAL FLUTED
FORM THROUGHOUT OR IN PART," to be as follows:-
My Invention consists of a machine or apparatus for making twisted nails
and other similar driving articles of a twisted or spiral fluted form throughout
or in part, either parallel or tapered, and of a plain, fluted, grooved, or
indented section throughout, or in part.
The machine or apparatus is capable of making one or more nails at any
number of revolutions or parts of a revolution of its driving gear, and when
the bars, rods, strips, or wire of iron, steel, brass, copper, or other metallic

page_text: alloy are placed in the machine, they are drawn into their required position
between the grippers at intervals by machinery or by hand, then gripped and
cut off into the required lengths, and held by jaws which are placed on the
ends of traversing and rotating mandrils, then headed by hammers or press
rods, and twisted by the traversing and revolving mandrils which draw the
pieces of iron when cut, as herein described, through rollers in front of the
grippers, so as to give them the required number of twists. The nails when
thus made drop out of the jaws, which open when the mandrils have travelled
their full distance.
The machine is constructed as follows:-A driving shaft is arranged on a
suitable framework or bed, and is driven by driving gear, to which motion can
be given by any known motive power from the said driving shaft by means of
cambs or cranks; the mandrils are made to travel to and from the grippers,
and upon the ends of the mandrils are self-acting jaws which form dies for the
heads of the nails, and in the centre of the mandrils are press rods, around
which the mandrils are made to rotate by means of friction rollers, revolving
cambs, or conical clutches upon a shaft, to which motion is given by the
driving shaft. The grippers are worked by a camb fixed on the shaft which
rotates the friction rollers, and the feeding apparatus composed of revolving
cambs and rollers is geared by wheels and worked by the said shaft, the whole
being arranged on requisite bearings and frame or bed.
I do not limit myself to any particular size of nail or form of head or point,
as my machine can be made of any size or strength and adjusted as may be
required; and if necessary the cutters and heading tools so formed as to give
any required form of point or head with or without slot, projection, or
indentation.
What I therefore claim as my Invention and desire to secure by." Letters
Patent" is, the right of applying the machine, apparatus, or its parts as herein
described to the manufacture of every kind of twisted nails and other similar
driving articles, both of a parallel and tapered form throughout or in part, and
also every kind of nail of a plain, indented, grooved, or fluted section to which
my machine or its parts may be made applicable by adjusting or arranging
one or more of its parts, and by making them of the requisite size or
strength.

by the said Montague Wigzell in the Great Seal Patent Office on the
8th February 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MONTAGUE
WIGZELL, late of Friar's Green, Exeter, in the County of Devon, and now of
the Strand, Topsham, in the said County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of August, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Montague Wigzell, Her special licence that I, the said Montague
Wigzell, my executors, administrators, and assigns, or such others as
I, the said Montague Wigzell, or my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter 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
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR MAKING PLAIN TWISTED NAILS,
SPIRAL FLUTED NAILS, AND OTHER SIMILAR DRIVING ARTICLES OF A TWISTED OR
SPIRAL FLUTED FORM THROUGHOUT OR IN PART," upon the condition (amongst
others) that I, the said Montague Wigzell, 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 Invention,
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 Montague Wigzell, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement:-
My Invention consists of a machine or apparatus for making twisted nails
and other similar driving articles of a twisted or spiral fluted form throughout
or in part, either parallel or tapered, and of a plain, fluted, grooved, or
indented section throughout or in part.
The machine or apparatus is capable of making one or more nails at any
number of revolutions or parts of a revolution of its driving gear, and when
the bars, rods, strips, or wire of iron, steel, brass, copper, or other metal or
metallic alloy are placed in the machine they are drawn into their required

page_text: position between the grippers at intervals by machinery or by hand, then
gripped and cut off into the required lengths and held by jaws which are
placed on the ends of traversing and rotating mandrils, then headed by
hammers or press rods and twisted by the traversing and revolving mandrils,
which draw the pieces of iron when cut as herein described through rollers in
front of the grippers, so as to give them the required number of twists.
The nails when thus made drop out of the jaws which open when the
mandrils have travelled their full distance.
The machine is constructed as follows and as shewn in the accompanying
Drawings: A driving shaft is arranged on a suitable framework or bed, and
is driven by driving gear, to which motion can be given by any known motive
power from the said driving shaft by means of cambs or cranks the mandrils
are made to travel to and from the grippers, and upon the ends of the
mandrils are self-acting jaws which hold the nails and form dies for the heads
of the nails, and in the centre of the mandrils are press rods, around which
the mandrils are made to rotate by means of friction rollers, revolving cambs,
or conical clutches upon a shaft, to which motion is given by the driving shaft.
The grippers are worked by a camb fixed on the shaft which rotates the
friction rollers, and the feeding apparatus composed of revolving cambs and
rollers is geared by wheels and worked by the said shaft, the whole being
arranged on requisite bearings and frame or bed.
I do not limit myself to any particular size of nail or form of head or point,
as my machine can be made of any size or strength, and adjusted as may be
required, and if necessary the cutters and heading tools so formed as to give
any requisite form of point or head, with or without slot, projection, or
indentation.
The accompanying Drawings, Plate 1 and 2, show in plan and elevation one
arrangement of the parts herein described which form the machine or appa-
ratus by means of which I make the nails and other similar driving articles
l:erein mentioned.
Plate I-A is the driving shaft to which motion is given by any known
motive power by means of pullies C, C, and is geared by wheels D, D; from
this shaft motion is given to shaft B (by wheels E, F,) which also work the
feeding apparatus I, I, by means of wheels G, H, Q, Q, on shafts S, R;
J, J, J, J, are fixed or moveable grippers worked by cambs in suitable frame
as K; L, L, are self-acting jaws or head pieces to mandrils M, M, which are
made to rotate by the friction rollers N, O, O, and to travel to and from the
grippers by the cambs P, P, on shaft A, and the hammer or press rods as
shown inside the mandrils are acted upon by the springs Y, Y, so as to form

page_text: the head of the nail at the right moment; the jaws are made to hold the nails
as they advance to the grippers by coming in contact with the face of gripper
blocks, and to open and release the nail when made by coming against a stop
or bearings Z, Z. The nail, rod, iron, or other material when passed through the
feeding apparatus is guided through the grippers as shewn in W, W, Plate I.
The various parts of the machine work through bearings X, X, T, U, Z, Z,
V, V, V, S, S, S, S, which are arranged on suitable framework or bed.
Plate 2 shows in solid lines the parts visable in a side elevation, each part
being lettered to correspond with the accompanying Drawing or Plan, Plate I.
What I therefore claim as my Invention and desire to secure by "Letters
Patent" is, the right of applying the machine, apparatus, or its parts as herein
described, to the manufacture of every kind of twisted nails and other similar
driving articles, both of a parallel and tapered form throughout or in part, and
also every kind of nail of a plain, indented, grooved, or fluted section to which
my machine or its parts may be made applicable by adjusting or arranging
one or more of its parts, and by making them of the requisite size or strength,
although my Invention principally relates to the manufacture of twisted or
spiral fluted nails and other similar driving articles by means of a combination
of the parts herein mentioned; but I wish it to be clearly understood that I
do not limit myself to the proportions or form of the parts as shewn in the
Drawings, provided the distinctive features of the Invention as set forth in this
my Specification are maintained.
