IMPROVE- MENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF CUT NAILS, SPRIGS, AND FLOORING BRADS
Year: 1876

page_text: LETTERS PATENT to Benjamin Mountain and Janies Mountain, both of
Hunslet, near Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN MACHINERY OR APPARATUS EMPLOYED IN THE MANUFACTURE OF
CUT NAILS, SPRIGS, AND FLOORING BRADS."
Sealed the 28th July 1876, and dated the 1st May 1876.
PROVISIONAL SPECIFICATION left by the said Benjamin Mountain and
James Mountain at the Office of the Commissioners of Patents on the 1st May
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 CUT NAILS, SPRIGS, AND FLOORING BRADS."
Our Invention consists in a combination of machinery or apparatus as hereafter
described, and in the arrangement of the various parts connected therewith,
producing a saving in labour, and rendering at the same time the working parts
of the machine less liable to get out of order and more accurate in their operation
than heretofore.
Within suitable framework we mount, side by side, two or more cutting heads
which are of ordinary construction, these by preference are caused to oscillate on
ono beam or fruine, a simultaneous motion being given to them from onu driving
shaft through suitable cranks, eccentrics, or their equivalents. In order to give the
required radial motion to the "screed" we dispense with the level gearings and
side levers now in use, and impart the required motion direct to the "screed"
carried by mes of a suitable lever, to which a radial motion is given from a
suitable revolving disc or its equivalent placed under the driving shaft.
By the above combination of machinery or apparatus one attendant can do the
work of two, and the machinery or apparatus works much more steadily and is not
so liable to get out of order.

the said Benjamin Mountain and James Mountain in the Great Seal Patent
Office on the 1st November 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 CUT NAILS, SPRIGS, AND FLOORING BRADS."
Our Invention consists in a combination of machinery or apparatus as hereafter
described, and in the arrangement of the various parts connected therewith,
producing a saving in labour, und rendering at the same time the working parts
of the machine less liable to get out of order and more accurate in their operation
than heretofore.
Within suitable framework we mount, side by side, two or more cutting heads
which are of ordinary construction, these by preference are caused to oscillate on
one beam or frame, a simultaneous motion being given to them from one driving
shaft through suitable cranks, eccentrics, or their equivalents. In order to give
the required radial motion to the "screed" we dispense with the bevel gearing and
side levers now in use, and impart the required motion direct to the "screed,"
carried by means of a suitable lever to which a radial motion is given from a
suitable revolving disc or its equivalent placed under the driving shaft.
By the above combination of machinery or apparatus one attendant can do the
work of two, and the machinery or apparatus works much more steadily and is not
so liable to get out of order.
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
Figure 1 represents a side elevation; Figure 2, a plan, looking at the top with
the cutting heads removed.
We mount on the framework a, side by side, two or more cutting heads b, which
are of ordinary construction; these cutting heads b are caused to oscillate on one
beam c, mounted on the framework a; a simultaneous motion being given to them
from one driving shaft through suitable cranks e and connecting rods f, or their
equivalents, motion being transınitted from some suitable motivo power to the
driving pulley and thence to the driving shaft d. In order to give the required
radial motion to the screed we dispense with the bevel gearing and side levers
now in use, and impart the required motion direct to the screed, conveyed thereto
by means of a lever i, to which a radial motion is given from the revolving disc J
placed under the driving shaft d, from which driving shaft the motion is trans-
mitted through gearing k. Through the outer end of the lever i we pass a vertical
shaft I, provided with the bearings m and n; on the upper end of the vertical
shaft is attached or carried a lever o; to the lever o is conveyed a radial motion
through vertical shaft & from the lever i. This radial motion is conveyed from the
lever o through bracket or rest p to tongs q, thence to the screed h, by which means
the screed is brought to the required angle each stroke of the machine to suit the
form of nail without the aid of the operator.
By the above combination of machinery or apparatus it works more steadily and
not so liable to get out of order.
Having now declared the nature of our said Invention, and shown by Drawings
how the same may be carried into practice, we would have it understood that wo
do not limit ourselves to the exact limits, details, or configuration of the parts we
have explained and shewn, as the same may of course be varied or modified without
in any way departing from our Invention; but what we do claim and desire to be

page_text: secured to us by Lettors Patent is, the arrangement and combination of the machino,
substantially as and for purposes heroin set forth.
In witness. whereof, we, the said Benjamin Mountain and James Mountain,
have hereunto set our hands and seals, this Thirtieth day of October, in
the year of our Lord One thousand eight hundred and seventy-six.
