IM- PROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF HEADING, CLASP, CLOUT, OR OTHER NAILS AND TACKS
Year: 1876

page_text: LETTERS PATENT to Benjamin Mountain and James Mountain, both of
Hunslet, near Leeds, in the County of York, for the Invention of " IM-
PROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE
OF HEADING, CLASP, CLOUT, OR OTHER NAILS AND TACKS."
Sealed the 21st December 1876, and dated the 25th September 1876.
PROVISIONAL SPECIFICATION left by the said Benjamin Mountain and
James Mountain at the Office of the Commissioners of Patents on the 25th
September 1876.
BENJAMIN MOUNTAIN and JAMES MOUNTAIN, both of Hunslet, near Leeds, in
the County of York. "IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED
IN THE MANUFACTURE OF HEADING, CLASP, CLOUT, OR OTHER NAILS AND TACKS."
Our Invention consists of an arrangement of machinery or apparatus as hereafter
described.
Within suitable framework we mount a cutting head of ordinary construction
provided with a convenient cutting tool, behind which are placed two spring gauges
to regulate the thickness of the nail instead of only one as on ordinary machines.
On the framework we fit, so as to work freely, two headers horizontally in a line
with each other and at opposite sides of the cutter.
We arrange our machine as follows to dispense with the turning over of the
screed," and for this purpose a radial motion is necessary to be imparted, and we
transmit the motion to the twist bar in a similar manner to that described in our
Patent dated 1st May, 1876, No. 1819. But as well as imparting a radial motion to
the "screed" we also impart thereto a lateral motion, which is effected by what we
call a "twist fork" to which the required motion is transmitted to the "twist fork"
through the twist bar to which it is connected. This motion can be regulated or
varied by means of the adjustment of a stud in the twist bar which works in a slot
in the arm of the twist fork."
"
Other parts of the machine are of ordinary construction, and motion is transmitted
to the machine from some suitable motive power in the usual manner.
" is
The advantage of our machine or apparatus are as follows:-The "screed
not required to be turned over to give the nail the correct taper. By having a
double action of the "screed we can make heading or other nails, whereas in

page_text: machines with the single motion or twist we can only form the heads of ordinary
floor nails. By the combined arrangement of two headers we are enabled to form
two heads simultaneously. By having two spring gauges for regulating the thick-
ness of nail ensures greater accuracy.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Benjamin Mountain and James Mountain in the Great Seal Patent
Office on the 24th March 1877.
BENJAMIN MOUNTAIN and JAMES MOUNTAIN, both of Hunslet, near Leeds, in
the County of York. "IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED
IN THE MANUFACTURE OF HEADING, CLASP, CLOUT, OR OTHER NAILS AND TACKS."
Our Invention consists of an arrangement of machinery or apparatus as hereafter
described.
Within suitable framework we mount a cutting head of ordinary construction
provided with a convenient cutting tool, behind which are placed two spring gauges
to regulate the thickness of the nail instead of only one as on ordinary machines.
On the framework we fit, so as to slide freely, two headers horizontally in a line
with each other and at opposite sides of the cutter.
We arrange our machine as follows to dispense with the turning over of the
"screed," and for this purpose a radial motion is necessary to be imparted, and we
transmit the motion to the twist bar in a similar manner to that described in the
Specification of our Patent dated the 1st May, 1876, No. 1819; but besides impart-
ing a radial motion to the "screed" we also impart thereto a lateral motion, which
is effected by what we call a "twist fork." The required motion is transmitted to
the "twist fork" through the twist bar to which it is connected. This motion cau
be regulated or varied by means of the adjustment of a stud in the twist bar which
works in a slot in the arm of the "twist fork."
Other parts of the machine are of ordinary construction, and motion is trans-
mitted to the machine from some suitable motive power in the usual manner.
"
The advantages of our machine or apparatus are as follows:-The "screed" is
not required to be turned over to give the nail the correct taper. By having a
double action of the "screed we can make heading or other nails, whereas in
machines with the single motion or twist we can only form the heads of ordinary
floor nails. By the combined arrangement of two headers we are enabled to form
two heads simultaneously. By having two spring gauges for regulating the thick-
ness of nail greater accuracy is ensured.
And in order that our Invention may be more completely understood reference
is given to the accompanying Sheet of Drawings and to the letters and marks
thereon.
DESCRIPTION OF DRAWINGS.

page_text: to the "twist fork" through the twist bar e, to which it is coupled by means of an
adjustable stud g. The lateral motion of the "twist fork" may be regulated by
adjusting the stud g in the twist bar c. The stud g works freely in the arm h of
the "twist fork" f.
Motion is transmitted to the headers from the driving shaft i through the
eccentric or crank J, connecting rods K, lever ₹ (which has its fulcrum at m), upright
rods n and knee joints or links o. The springs are to assist in the return motion
of the headers d after each operation.
Other parts of the machine not described are of ordinary construction.
Having now described the nature of our said Invention, and shewn by Drawings
how the same may by carried into practice, we would have it understood that we
do not limit ourselves to the exact details or configuration of the parts we have
explained and shewn, as the same may be varied or modified without departing
from our Invention, but what we claim and desire to be secured to us by Letters
Patent is,-
First. The arrangement and construction of twist bar and fork whereby not only
a radial but a lateral movement is given to the "screed," dispensing with the turn-
ing over thereof, substantially as herein set forth.
Second. The application of headers d placed in a line with each other and at
opposite sides of the cutter, substantially as and for purposes herein set forth.
Third. The combination of the various parts forming the machine, substantially
as herein set forth.
In witness whereof, I, the said James Mountain, for myself and on behalf of the
said Benjamin Mountain, have hereunto set my hand and seal, this Twenty-
third day of March, in the year of our Lord One thousand eight hundred and
seventy-seven.
JAMES MOUNTAIN. (L.S.)
