Year: 1875

page_text: LETTERS PATENT to Henry Rogers, of the Firm of Henry Rogers,
Sons, and Company, of Wolverhampton, in the County of Stafford,
Merchants, for the Invention of "IMPROVEMENTS IN CHISEL POINTED CUT
NAILS AND IN MACHINES FOR THE MANUFACTURE OF THE SAME."-A com-
munication from abroad by Henry Mullholland, of Montreal,
Canada.
Sealed the 4th June 1875, and dated the 15th January 1875.
PROVISIONAL SPECIFICATION left by the said Henry Rogers at the
Office of the Commissioners of Patents, with his Petition, on the
15th January 1875.
I, HENRY ROGERS, of the Firm of Henry Rogers, Sons, and Company,
of Wolverhampton, in the County of Stafford, Merchants, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN CHISEL
POINTED CUT NAILS, AND IN MACHINES FOR THE MANUFACTURE OF THE SAME," to
be as follows :—
The first part of the said Invention consists in making the said chisel
pointed nails with a head formed by the compression or upsetting of the

page_text: metal at the head part of the nail, the head formed being similar to that
of a common cut nail.
The second part of the said Invention relates to machines for manu-
facturing the said chisel pointed and headed cut nails. -
The said machines consist of combinations of parts mainly resembling
those of ordinary cut nail machines, but the said machines are provided
with dies suitable for cutting the chisel point of the nail and the
necessary adjuncts for working and supporting the said dies. The fixed
cutting die is secured on the bed of the machine and the moveable
cutting die to a cutter head worked from the driving shaft by a crank
plate and pin and connecting link and lever. The gripping lever is of
the ordinary construction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Rogers in the Great Seal Patent Office on
the 28th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
ROGERS, of the Firm of Henry Rogers, Sons, and Company, of Wolver-
hampton, in the County of Stafford, Merchants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of January, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Henry Rogers, Her special
license that I, the said Henry Rogers, my executors, administrators, and
assigns, or such others as I, the said Henry Rogers, my executors, ad-
ministrators, 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 CHISEL
POINTED CUT NAILS, AND IN MACHINES FOR THE MANUFACTURE OF THE SAME," (a
communication to me from abroad by Henry Mullholland, of Montreal,
Canada,) upon the condition (amongst others) that I, the said Henry
Rogers, my executors or administrators, by an instrument in writing

page_text: 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 Henry Rogers, 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 :-
The first part of the said Invention consists in making the said chisel
pointed nails with a head formed by the compression or upsetting of the
metal at the head part of the nail, the head formed being similar to that
of a common cut nail.
The second part of the said Invention relates to machines for manu-
facturing the said chisel pointed and headed cut nails.
The said machines consist of combinations of parts, mainly resembling
those of ordinary cut nail machines, but the said machines are provided
with dies suitable for cutting the chisel point of the nail and the
necessary adjuncts for working and supporting the said dies. The fixed
cutting die is secured on the bed of the machine, and the moveable
cutting die to a cutter head worked from the driving shaft by a crank
plate and pin and connecting link and lever. The gripping lever is of
the ordinary construction.
Figure 1 represents in edge view and Figure 2 in elevation the chisel
pointed cut nail before it has been headed; and Figure 3 represents in
edge view and Figure 4 in elevation the said cut nail after it has been
headed by upsetting or compressing the head part. The chisel point of
the nail is marked a, and the head part of the cut nail is expanded at b,
the sides of the head part & making the same angle with the body of tho
nail as the sides of the chisel point a. The expanded head part of the
cut nail, Figures 1 and 2, is compressed or upset to form the head c to
the chisel pointed and headed nail, Figures 3 and 4.
The machine which it is preferred to use for cutting the nail, Figures 1
and 2, from the strip or nail plate, and compressing or upsetting the
head c on the said cut nail is illustrated in Figures 5, 6, 7, and 8,
Figure 5 being a plan of the improved machine for making headed nails

page_text: with chisel points; Figure 6, a front clevation of the same; Figure 7, a
side elevation of the same; and Figure S, a longitudinal vertical section
of the same taken on the line A, A, Figure 3, the said Figure 8 being
drawn to a larger scale than Figures 5, 6, and 7.
The same letters of reference indicate the same parts in Figures 5, 6,
7, and 8.
a is the bed for holding the working parts, having uprights b for sup-
porting the revolving shaft c, the said shaft c being rotated by any
suitable power and imparting motion to the other parts of the machine.
d is the cutter head worked by the lever e, the latter being actuated by
the link fand crank ping on the disc, the said disc being fixed on the end
of the principal shaft c and revolving with it. i is a frame carrying the
header & worked from the projection of the cutter head d in the ordinary
manner; -m is the gripping lever operated by a cam or excentric non
the shaft c; o is the nipper for catching the blank when cut.
The parts described are constructed, arranged, and operated as in the
ordinary machines at present in use for making the common cut nail,
but with the before-mentioned parts of the machine are combined the
following parts whereby the machine is fitted to cut the chisel pointed
nails, Figures 1 and 2, before the head c, Figures 3 and 4, is upset upon
the head part of the cut nail.
'
The parts by which the chisel pointed nails are cut consist of the
cutter dic P fixed to the cutter head d, and a bed die q secured in the
bed 1.
The said cutter die pand bed cutter die q have the necessary
configuration given to them for cutting the chisel pointed nails, Figures 1
and 2. By the addition of the cutting die p and bed die q the chisel
pointed nail of the shape of Figures 1 and 2 is first cut from the nail
plate or strip fed between the said parts p and q, and the said cut nail
afterwards headed by the advance of the heading tool k, and the head c
formed or upset on the head end of the nail, as represented in Figures 3
and 4, the cut nail being held during the heading operation by the
nipper o and gripping lever m as in ordinary cut nail heading machines.
Having now described the nature of the said Invention, and the
manner in which the same is to be performed, I wish it to be understood
that I claim as the said Invention,―
First. The improvement in chisel pointed nails herein-before described
and illustrated in Figures 1, 2, 3, and 4 of the accompanying Drawing,

page_text: that is to say, forming a head on chisel pointed cut nails by upsetting or
compressing the metal at the head part of the nail, substantially as
described and illustrated.
Secondly. The improvements in machines to be employed in the
manufacture of the said upset headed chisel pointed nails herein-before
described and illustrated in Figures 5, 6, 7, and 8 of the accompanying
Drawing, that is to say, the combination of the cutter head d, header k,
gripping lever m, and nipper o, with the cutter dies P and q, substantially
as and for the purposes set forth.
In witness whereof, I, the said Henry Rogers, have hereunto
set my hand and seal, this Fifteenth day of June, in the year
of our Lord One thousand eight hundred and seventy-five.
Witness,
MATTHIAS HENRY STEDMAN,
