Year: 1861

page_text: LETTERS PATENT to Montague Wigzell, of the Strand, Topsham, in the
County of Devon, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS TO BE USED IN MOULDING AND CASTING TWISTED NAILS, SPIRAL
FLUTED NAILS, BOLTS, AND SCREWS FOR SHEATHING VESSELS, SHIPBUILDING,
BUILDING, AND OTHER PURPOSES."
Sealed the 29th April 1862, and dated the 14th November 1861.
PROVISIONAL SPECIFICATION left by the said Montague Wigzell at the
Office of the Commissioners of Patents, with his Petition, on the 14th
November 1861.
I, MONTAGUE WIGZELL, of the Strand, Topsham, in the County of Devon,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS TO BE USED IN MOULDING AND CASTING TWISTED NAILS,
SPIRAL FLUTED NAILS, BOLTS AND SCREWS FOR SHEATHING VESSELS, SHIPBUILDING,
BUILDING, AND OTHER PURPOSES," to be as follows:-
My Invention relates to improvements in machinery or apparatus to be
used in moulding and casting twisted nails, spiral fluted nails, sheathing nails
of a twisted or spiral fluted form, and other similar driving articles, with or
without a slot hole or projection on the head, and of a plain, fluted, grooved,
ribbed, or indented section throughout or in part, and either parallel or
tapered throughout or in part, also bolts, screws, and other articles to which it
may be made applicable, and it consists of a plate or plates fitted with any
number of nuts, through which screws of the required pitch work; on the
ends of these screws are attached the screws or twisted form of nail, forming

page_text: the patterns of the articles to be made, which patterns, by being made to
descend screw themselves into the sand or other material used instead of sand,
and produce the required form or mould. The plate or frame containing the
screws is made to rise or fall by a screw or lever, by hand or any known
motive power, and this plate or frame when raised carries with it the screws
and patterns of the nails or other articles to be made, and causes them to
twist or unscrew themselves out of the mould. The flask containing the sand
or other material used when placed under the machine is made to rise or press
against the lower plate of the machine, so as to be ready to receive the
descending patterns of the nails, or other articles to be made. The machine
can be made to make any number of moulds or impressions in the sand at one
operation.
What I more particularly claim and wish to secure by Letters Patent, is
the application of the machine, apparatus, or its parts; as herein described, to
moulding and casting twisted nails, spiral fluted nails, bolts, and screws, in
brass, copper, iron, and other metal, or metallic alloy, and all other articles to
which the machine may be applicable.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Montague Wigzell, in the Great Seal Patent Office on the
14th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MONTAGUE
WIGZELL, of the Strand, Topsham, in the County of Devon, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourteenth day of November, 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 terin. 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 "IN-
PROVEMENTS IN MACHINERY OR APPARATUS TO BE USED IN MOULDING AND CASTING
TWISTED, NAILS, SPIRAL FLUTED NAILS, BOLTS AND SCREWS FOR SHEATHING
VESSELS, SHIPBUILDING, BUILDING, AND OTHER PURPOSES," upon the condition

page_text: (amongst others) that I, the said Montague Wigzell, my executors or adminis-
trators, 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
thereof, that is to say:-
::
My Invention. relates to improvements in machinery or apparatus to be
used in moulding and casting twisted nails, spiral fluted nails, sheathing nails
of a spiral fluted form, and other similar driving articles, with or without a
slot, hole, or projection on the head; and of a plane, fluted, grooved, ribbed, or
indented section throughout or in part, either parallel or tapered throughout
or in part, also bolts, screws, and other articles, to which it may be made
applicable; and it consists of a plate or plates fitted with any number of nuts;
through which screws of the required pitch work; on the ends of these screws
are attached the screws or twisted form of nails forming the patterns of the
articles to be made, which patterns by being made to descend screw themselves
into the sand, or other material used instead of sand, and produce the required
form or mould. The plate or frame containing the screws, is made to rise or
fall by a screw or lever, by hand or any known motive power, and this plate or
frame when raised carries with it the screws and patterns of the. nails or
other articles to be made, and causes them to twist or unscrew themselves
out of the mould; the nuts through which the screws work being fixed and
arranged on suitable framework or stand.
I sometimes use a series of tooth wheels, worked by a rack or racks, for
the purpose of twisting the patterns or twisted form of articles to be made, in
and out of the sand, or other material used instead of sand, and I attach the
said patterns to spindles which work through the said wheels, and are made to
rise and fall by being attached to a plate, which is worked up and down by a
screw or lever. The flask or flasks containing the sand or other material
used, when placed under the machine is made to rise or press against the
lower plate of the machine, so as to be ready to receive the descending
patterns of the nails or other similar driving articles to be made, by means of
a screw, lever, or camb, and to travel to and from the machine upon a move-
able truck or bed, running on smooth or toothed wheels, worked by a rack or
other suitable means.

page_text: The machine can be made to make any number of moulds or impressions
in the sand at one or more operations, and I do not limit myself to any par
ticular size of machine or articles to be made, and what I more particularly
claim and wish to secure by "Letters Patent" is the application of the
machine apparatus or its parts, as herein described, to moulding and casting
twisted.nails, spiral fluted nails, bolts and screws in brass, copper, iron, and
other metals or metallic alloy, and other articles to which the machine may be
made applicable.
The accompanying Drawings, Fig. 1, Plate 1, is a front elevation of a
moulding machine or apparatus, as herein described, of which Fig. a is
one of a series of patterns of articles to be made, which patterns may be
straight or.twisted; Fig. 6 is one of the spindles or screws attached to the
pattern as a. Figs. c are the fixed nuts through which the screws or spindles
b work, and d is the lower plate, into which the patterns rise when drawn
from the mould or sand; on to this plate I sometimes fix the heads of the
nails and the runners; Fig. e, moving on guides f, f, is the plate in which the
screws or spindles, revolve when the said plate is raised or lowered by a screw
or lever with rack and pinion as 9, shown in Fig. 1, Plate 1, and g, h, i, Fig. 2,
Plate 2.
Fig. 2, Plate 2, is a side elevation of Fig. 1, Plate 1, showing the machine
with the parts arranged for making moulds for casting sheathing nails, the
patterns of which are represented as being in the sand contained in the flask,
as Fig. 3, which flask is shown on truck 4, travelling on wheels 5, 5. Figs.
7, 8, 9, 10, 11, represent vertical spindle roller, camb, horizontal spindle, and
lever for pressing the sand or flask close up to the plate d, as Fig. 3, the whole
being arranged on the requisite framework, guides, nuts, pins, and sitscrews.
In witness thereof, I, the said Montague Wigzell, have hereunto set
my hand and seal, the 13th day of May, in the year of our Lord 1862.
