IMPROVEMENTS IN MACHINERY FOR MAKING NAILS, AND FOR OTHER ANALOGOUS PURPOSES WHERE METAL IS COMPRESSED BY DIES OR STAMPS
Year: 1858

page_text: LETTERS PATENT to Thomas Till, of Hooper Street, in the Borough
of Birmingham, in the County of Warwick, Mechanic, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY FOR MAKING NAILS, AND FOR
OTHER ANALOGOUS PURPOSES WHERE METAL IS COMPRESSED BY DIES OR
STAMPS."
Sealed the 3rd May 1859, and dated the 5th November 1858.
PROVISIONAL SPECIFICATION left by the said Thomas Till at the
Office of the Commissioners of Patents, with his Petition, on the
5th November 1858.
1, THOMAS TILL, of Hooper Street, in the Borough of Birmingham, in the
County of Warwick, Mechanic, do hereby declare the nature of the said
Invention, for, "IMPROVEMENTS IN MACHINERY FOR MAKING NAILS, AND
OTHER ANALOGOUS PURPOSES WHERE METAL IS COMPRESSED BY DIES OR STAMPS,"
to be as follows:-
They consist in constructing a machine so that a crank in or cam on the
driving shaft, acting in its revolution upon a bar, moves or slides it lengthwise
to and fro, and thus causes two headers, placed one in each end of the bar, to
work alternately in making the heads to nails or other compression, and so
that a similar device on the same shaft, acting upon a series of levers, or other
suitable arrangement connected to the movable holding and pointing die, the
other being stationary, holds and points the nail just before the action of the
heading dic.

page_text: The material to be manufactured may also be fed in by a third similar
crank or cam motion on said shaft, or by some other mode operating upon
the feeding arrangements in such a manner that enough of the end for the
head or part to be compressed is projected the proper distance beyond the
holding dies at the right time for the headers. These devices may all be used
in combination, or the first without the others, or the two first in combination
without the third.
The first-named cam or crank may be made to act in the course of
revolution upon more than one bar, and for this purpose bars may be placed
like spokes in the hub of a wheel, in the centre of which a female cam may
be constructed for the cam or crank to work upon.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Till in the Great Seal Patent Office on the 5th
May 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS 1
TILL, of Hooper Street, in the Borough of Birmingham, in the County of
Warwick, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of November, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of 2
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Till, Her special license that I, the said Thomas Till,
my executors, administrators, and assigns, or such others as I, the
said Thomas Till, 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 "IMPROVE-
MENTS IN MACHINERY FOR MAKING NAILS, AND FOR OTHER ANALOGOUS PURPOSES
WHERE METAL IS COMPRESSED BY DIES OR STAMPS," upon the condition (amongst 3
others) that I, the said Thomas Till, or 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 3
next and immediately after the date of the said Letters Patent.

page_text: NOW KNOW YE, that I, the said Thomas Till, 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, reference being had to the Drawings hereunto annexed, and to the
letters and figures marked thereon, that is to say:-
The improvements consist in constructing a machine so that a cam upon or
a crank in a driving shaft acting in its revolution upon a bar moves or slides
it lengthwise to and fro, and thus causes two headers, placed one in each end
of the bar, to work alternately in making the heads to nails or other com-
pression, and so that a similar device upon the same shaft, acting upon a
series of levers, or other suitable arrangement connected to the moveable
holding and pointing die, the other being stationary, holds and points the nail
just before the action of the heading die.
The material to be manufactured may also be fed in by a third similar
crank or cam motion on the said shaft, or by some other mode, in such
manner that enough of the end for the head or part to be compressed is pro-
jected the proper distance beyond the holding dies at the right time for the
header. These devices may all be used in combination, or the first without
the other two, or a combination of the two first-mentioned devices without

page_text: of a flat piece of steel, or they may be made in two separate pieces, as shown;
they are adjusted by means of set screws (P), and are kept down by the
screw pins (Q), or by dovetail wedges. These dies cut off the length of wire
or rod, and form the point of the nail by compression; they also retain the
nail in place, whilst the head is formed by the blow or pressure of the heading
bolt (F). The dies are worked by the sliding bar (R), receiving its motion
from the cam (S), thus forcing the dies backwards and forwards, as required,
through the action of the inclined plane (T) and friction rollers U, as seen in
the plan. The second friction roller (U') is fixed upon an eccentric pin, and
answers the purpose of throwing one side out of play, whilst the other is in
action, thus a fresh coil of wire or rod can be supplied without stopping the
machine.
In order to adapt the machine above described for other purposes analogous
to that herein mentioned, suitable dies must be substituted for those I have
shewn, as it will be evident that the form of die used will depend upon the
purpose to which the machine is to be applied. The machine may be worked
by steam or other suitable power.
Having thus described the nature of my said Invention, and in what manner
the same is to be performed, I claim the arrangement and combination of the
several parts herein described and shewn in Drawings, or the mere equivalents
of those parts forming machinery for making nails, and for other analogous
purposes where metal is compressed by dies or stamps, as herein more fully
set forth and specified.
In witness whereof, I, the said Thomas Till, have hereunto set my
hand and seal, this Fourth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine.
THOMAS TILL.
