PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Scissors and Shears.
We, ALBERT CLARKE, Gloucester Street, Scissor Manufacturer, and WILLIAM
THOMAS WHEATLEY, of Eclipse Works, Manufacturer, both of Sheffield in the County
of York, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the manufacture of Scissors and Shears
and more particularly to the process of stamping same, so as to save labour in forging
and grinding, and thus cheapen production.
We are aware that it has been proposed to partly forge or draw out the scissor
blanks and then to partially shape them by stamping them in dies, we do not wish to
claim stamping alone, or stamping in connection with hand forging, but our invention
goes further, carrying out what has hitherto been stated to be commercially impractical
namely the combination of punching out and stamping.
In carrying out our invention we punch out of strips of steel a blank of one complete
half or side of the scissor; that is the bow, shank, and blade, and we then place the
blank so produced and heated to the required degree in suitable tools, and stamp the
said blank on both its sides to the shape or configuration required either plain or
ornamental as the case may be.
By this improved combination of the processes of cutting out or punching a
complete blank of the bow, shank and blade, and then stamping them to the finished
form in dies, greater uniformity is obtained, each one being a facsimile of the other,
this dispenses with the tedious process of "matching or selecting the parts for pairs,
as requires to be done at the present time, and the bows and joints require less
finishing than those made by ordinary processes.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Scissors and Shears.
We, ALBERT CLARKE, Gloucester Street, Scissor Manufacturer, and WILLIAM
THOMAS WHEATLEY, of Eclipse Works, Manufacturer, both of Sheffield, in the
County of York, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statenient :-
This invention relates to improvements in the manufacture of Scissors and Shears,
and refers more particularly to the process of stamping same in contradistinction to
forging by hand; the object being to save labour, especially in forging, filing, and
grinding, and thus cheapen production.
We are aware that it has been proposed to partly forge or draw out the blank of
a Scissor or Shear, and then to partially shape such blanks by stamping them in dies ;
now we wish it understood that we do not claim the process of stamping alone, or
stamping in connection with hand forging, but we go further, and accomplish what
has hitherto been considered to be commercially impracticable in the manufacture
of such articles, namely the combination of the process of punching or flying out, and
stamping.
In carrying out our invention we first punch or fly out of strips or other pieces
of steel, a blank of one complete half or side of the Scissor or Shear, namely the
bow, shank and blade, the inside of opening through the bow being a separate

page_text: We then place the blank so produced, and heated to the required degree, between
suitable stamping tools, the faces of which are prepared with a matrix corresponding
with the shape of the blank, and of the pattern which it is desired to produce; and
we stamp the blank in the ordinary manner of stamping.
This process usually produces a slight "fash" upon the edges of the article, and
to save filing and grinding, we remove the fash by means of beds and punches of a
shape corresponding with the configuration of the blank.
By the novel combination of the processes of cutting out, punching, or flying out
a complete blank of one half of a Scissor or Shear, and then stamping them to the
finished plain or ornamental form and pattern, in dies or matrices, perfect uniformity
is obtained, by which the tedious manual labour of matching or selecting the blanks
in pairs is entirely dispensed with, and the bows and joints require less filing, and
finishing than those made by the processes at present in use.
Having thus particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is performed, we declare that what we claim is :-
1-In the manufacture of Scissors and Shears the combination of the processes of
punching out the blank of one complete half of the article, with the process of stamping
both sides of the said blank to the required configuration, for the purpose specified and
substantially as described.
2-The process of manufacturing Scissors and Shears, by first punching out the
blank of one complete half of the article, second by stamping both sides of the said
blank to the required configuration, and third by cutting off any outside fash with
suitable beds and punches substantially as hereinbefore described.
