IMPROVEMENTS
IN THE MANUFACTURE OF SHUTTLE TONGUES, THE BLADES OF TABLE KNIVES,
LIKE ARTICLES, AND IN THE MACHINERY, APPARATUS, OR MEANS
AND OTHER
EMPLOYED THEREIN.
This Invention consists in the application of a peculiar system or mode of forging
to the manufacture of shuttle tongues employed in looms for weaving, and to the
forging and shaping of the blades of table knives and other like articles; also in the
application of certain special forms of rolls and dies to the forging and shaping of
the class of articles above mentioned.
In manufacturing shuttle tongues according to my Invention, I first roll a length
of metal of a width equal to about the length of one or of two shuttle tongues, and
of such a section as to leave a longitudinal thickened or raised part along the plate
(in the centre thereof or otherwise), the side portion or portions of the said plate
being slightly tapered off from the thickened or raised part towards the outer edge
or edges of the plate. These plates are produced by rolls of a peculiar form, that is
to say, having grooves and projections therein or thereon, specially adapted for the
production of the particular section of plate required. The said rolled plates may
be of any desired length, and after having been rolled they are cut or puncheit
transversely into narrow strips of any breadth required (say from about of an
nch to of an inch), which strips are formed into rough blanks, presenting the
appearance of a single shuttle tongue, or of two tongues joined together at their
butts or thickened ends (as the case may be) by pressure in a die or matrix of the
shape required. These rough blanks shaped as above (if made double) are (either
116
3: the

page_text: before or after stamping) cut in two transversely in the middle so as to form iwo
single blanks, each having a tapering shank and a thickened end to form the butt.
These single blanks are further shaped or finished to the form required by pressure
or stamping between an upper and a lower finishing die or matrix, the one
serving to shape the upper half or portion, and the other the under half or portion
of the tongue.
The same system or mode of manufacture is obviously equally applicable to the
forging of the blades of table knives and other like articles, the shape of the rolls
and dies or stamps being of course made to conform to that of the blanks required.
The dies or stamps which I employ in the aforesaid manufacture may be mounted
in and actuated by any well known apparatus or machine heretofore used in stamp-
ing and forging metals.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William "Nicholson in the Great Seal Patent Office on the 11th

· IMPROVEMENTS
IN THE MANUFACTURE OF Suctyle TONGUES. THE BLADES OF TABLE KNIVES.
AND OTHER LIKE ARTICLES, AND IN THE MACHINERY, APPARATUS, OR MEANS
EMPLOYED THEREIN.
My said Invention consists in the application of a peculiar system or mode of
forging to the manufacture of the tongues of shuttles employed in tooms for weaving,
also to the forging and shaping of the blades of table knives and flyers for spinning
frames, and in the application of certain special forms of rolls and unes to the forging
and shaping of the class of articles above mentioned.
In manufacturing or forging shuttle fongues according to my Invention I first
roll a metal plate of a width equal to about the length of one or of two shuttle
tongues, and of such a section as to leave a longitudinal thickened or raised part
along the plate (in the centre thereof or otherwise), the side portion or portions of the
said plate being slightly tapered off from the thickened or raised part towards the
outer edge or edges of the plate. These plates are produced by rolls shaped or
specially adapted in the protuction of the particular section of plate required. The
said rolled plates, which are rolled lengthways as well as across the metal, may be of
any desired length, and after having been rolled or shaped they are cut or punched
transversely into narrow strips or blanks of any breadth required (say, from three-
eighths to seven-eighths of an inch) by means of a cutting die of the requisite shape
to produce either double or single blanks, that is to say, either two blanks joined
together at the butts or thickened part representing two shuttle tongues, or blanks
representing single tongues only. These rough blanks shaped as above (if made
double) are either before or after stamping cut in two transversely in the middle so
as to form two single blanks, each having a tapering shank and a thickened end to
form the butt. These single blanks are further shaped or finished to the form
required by pressure or stamping between an upper and a lower finishing die or
matrix, the one serving to shape the upper half or portion, and the other the under
half or portion of the tongue.
The same system or mode of manufacture is obviously equally applicable to the
forging of the blades of table knives and to the forging of the flyers for spinning
frames, the shape of the rolls and dies or stamps being of course made to conform to
that of the blanks required.
And in order that my said Invention may be fully understood I shall now proceed
more particularly to describe the same, and for that purpose shall refer to the
several Figures on the explanatory Sheet of Drawings hereunto annexed, the
same letters of reference indicating corresponding parts in all the corresponding
Figures.

the slightly tapering sides of the sand plate. From this plate I cut transversely by
means of the hollow die (Figure 2) a number of double blanks, the outline of
which is clearly indicated in Figure 2. These double blanks, ent out as described.
are then divided transversely across the thickened part so as to form two single
blanks, each having a tapering shank and a thickened end to form the butt, which
blanks are further shaped and finished to the form shown in Figure 6 by the action
of the upper and under die and matrix and e. (Figures 3, 4, and 5.) which are
subjected to pressure or stamping in any well known manner.

articles may be mounted in and actuated by any well known apparatus or machine
heretofore used in the stamping and forging of metals,

would observe in conclusion that what I consider to be novel and original, and
therefore claim as the Invention secured to me by the herein-before in purt
recited Letters Patent is; the mode or method of making shuttle tongues, the blade:
of table knives, and flyers for spinning frames from rolled metal plates of suitable
sertion by the application and use of stamps and dies, substantially in the manner
hereinbefore described and illustrated by my Drawings.

hand and seal, this Tenth day of September, in the year of our Lord One
