WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of July, in the year

page_text: of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Benoni Pechenart and Louis Miette, Her
special licence that we, the said Benoni Pechenart and Louis Miette,
our executors, dministrators, and assigns, or such others as we, the said
Benoni Pechenart and Louis Miette, our 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, usc, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
THE MANUFACTURE OF NAILS," upon the condition (amongst others) that
we, the said Benoni Pechenart and Louis Miette, our executors or
administrators, by an instrument in writing under our or their hands
and scals, or under the hand and scal of one of us or them, should par-
ticularly 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 Louis Miette, on behalf of the
said Benoni Pechenart and myself, 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) :-
This Invention relates to improvements in machinery or apparatus for
the manufacture of nails, the construction of which will be understood
by reference to the accompanying Drawings and the description thereof
which follows.
Fig. 1 is a plan view illustrating our Invention as applied to a nail-
cutting apparatus of a well-known kind, which is shown in red; Fig. 2
is a side elevation of the same; Fig. 3 is a transverse section through
the line A, B, of Figs. 1 and 2; Fig. 4 is a section to an enlarged scale
of the shifting piece or clutch taken through the line C, D, of Fig. 1;
and Fig. 5 is a full-size section of the pincers taken through the
line E, F, of Figs. 1 and 2.
a is a pinion on the main shaft a¹; b, toothed wheel driven by the
pinion a, and forming a crank; c, slots for lengthening or shortening
the connecting rod; d, connecting rod; e, e, bearings for the shaft g;

page_text: f, shifting piece or clutch for throwing in and out of gear; this piece
or clutch is capable of endwise movement along the shaft g, but is
prevented from turning thereon by the keys g¹; f, clutch piece actuated
by the connecting rod d, and capable of rotating on the shaft g when
not in gear with the piece f; h, toothed bevil wheel (fixed on the shaft g)
which drives the bevilled pinion i, which latter is fixed on and moves
the hollow spindle j, into which the nail rod or plate is introduced;
k, holding bolt; 1, rod which pushes the nail rod or plate towards the
pincers. This rod is formed with a notch or recess at its fore end
to receive the end of the nail rod or plate; m, m³, guides or rails;
n, n', guide rollers working on the axles of the carrier n², and drawn
along by means of bands of leather or cords p, p, at the bottom of
which are weights passing over the pullies o, o¹; q, lever for actuating
the shifting piece or clutch f; r, fulcrum pin on which the lever q
works; r¹, stud or pin attached to the bar q', which latter at its other
end carries a forked piece provided with pins taking into a groove
or recess formed around the shifting piece or clutch f, as shewn;
q, spring; 8, 8, bearings of the hollow spindle j; j, holding down
spring; t,t, screws for regulating the pincers; u, piece carrying the
pincers; v, v¹, the pincers for holding and presenting the nail rod or
plate for making the nails; v², v³, fulcra of pincers; w, adjustable sup-
port; x, nail rod or iron plate of which the nails are to be made;
2, framing of the apparatus.
The operation is as follows:-The main shaft a¹ being caused to rotate
in the usual manner, and carrying round with it the pinion a which
turns the toothed wheel b, a semi-rotative or rocking motion is commu-
nicated through the connecting rod d to the clutch piece f¹ for actuating
the apparatus. In order to place the nail rod or plate x within the
hollow spindle j the clutch piece f is thrown out of gear with the clutch
piece f¹ by moving the lever q into the position indicated by the dotted
line in Fig. 1, which movement of the lever will move the clutch piece f
into the position in which it is represented by dotted lines in the same
Figure, so that the clutch piece f¹ will then partially rotate to and fro
on the shaft g without giving motion to it. The rod is also withdrawn
from the hollow spindle j, into which a nail rod or plate of iron x of the
requisite dimensions is then introduced, its fore end passing between
the pincers v, v¹, which are to be adjusted to the nail rod or plate by
means of their screws t, t. The rear end of the nail rod or plate x takes
into the recess or slot in the fore end of the rod 7; the rear end of the

page_text: rod passes through a circular hole in the central part or portion of
the carrier n², which is drawn forward by the weights already described,
so as to feed the nail rod or plate to the cutters, the rod 7 being free to
partake of the partial rotation of the nail rod or plate x and hollow
spindle j. On moving the lever q into the position in which it is shewn
in full lines in Fig. 1, and thereby bringing the clutch piece finto gear
with the clutch piece f¹, the rocking motion of the latter will be com-
municated to the shaft g, and from it through the wheel h and pinion i
to the hollow spindle j and pincers, thereby turning over the nail rod or
plate after each cut as required.
† Our improved feeding apparatus as described is very simple in con-
struction, and enables nails to be manufactured with great rapidity,
and it may obviously be employed in conjunction with other kinds of
nail cutting apparatus than the one which we have shewn in red in
the Drawings for the purpose of illustrating the application of our
Invention.
And having now described the nature of our said Invention for
"Improvements in Machinery or Apparatus for the Manufacture of
Nails," and in what manner the same is to be or may be performed
or carried into practical effect, we hereby declare that we do not claim
as novel or original the feeding of a nail rod or plate to the cutting
apparatus by self-acting means, as we are fully aware that it has been
previously proposed to do this in various ways; nor do we claim as of
our Invention or the exclusive use of any of the several parts herein-
before described and referred to, except when the same are employed
in and for our said Invention, which we hereby declare to consist in
the combination of parts forming the improved feeding apparatus con-
structed and arranged as herein-before described and illustrated in the
accompanying Drawings.
In witness whereof, I, the said Louis Miette, have hereunto set my
