Improvements in the Manufacture of Coke and other
TUTAS.
AUGUSTUS EDWARD STAYNER of Millhouses near Sheffield Managing Director and
WILLIAM ROBERTS of 104 Seller Street Heeley Sheffield Manager do hereby declare
the nature of this invention to be as follows:-
The forming of Blanks out of solid slabs or bars of Steel in such manner as to fit the
parts intended for the prongs to be drawn out under the hammer. In carrying out
this object we take a slab or bar of the required size and partially split two portions
from one side of the slab in such a way as to leave a projection-commonly known as
a Plug-in the centre, then on the other side of the slab we punch holes of the required
shape and at the required distance from what may be termed the back or bar of the
fork, then by splitting the slab.outwards from these.holes we form the portions that
represent the prongs when drawn out under the hammer.

page_text: We, AUGUSTUS EDWARD STAYNER, of Millhouses, near Sheffield, Yorkshire, Manag-
ing Director, and WILLIAM ROBERTS, of 104 Seller Street, Heeley, Sheffield, Yorkshire,
Manager, 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
statement:
The forming of Blanks out of solid slabs of steel in such a manner as to fit the
parts intended for the prongs to be drawn out under the hammer.
In carrying out this object we take a slab or bar of the required size and partially
split two portions from one side of the slab in such a way as to leave a projection
commonly known as a plug, in the centre, then on the other side of the slab, we punch
holes of the required shape and at the required distance from what may be termed the
back or bar of the fork, then by splitting the slab outwards from the holes, we form
the portions that represent the prongs, when drawn out under the hammer.
that the mode of carrying out this invention may be thoroughly understood, we annex
a sheet of drawings illustrating each stage of the process of forming the blanks ready
to be drawn out into forks, under the hammer.
In order
Fig. 1. represents a slab of steel with slits s. s. p. p. severing two portions a. a. and
leaving a blank as represented in Fig. 2.
The same result is also obtained by making the slits s. s. only as shown in Fig. 7.
and using a shorter slab, and then drawing it down under a hammer into the form
shown in Fig. 2. By this latter method, much waste of material is avoided.
The projection c. is what is commonly known as the plug, to form the tang, socket,
or straps, for attaching the handle to the fork, in the ordinary way, and may be any
desired size.
Fig. 3. represents the blank perforated with holes d. d. leaving a portion g. to form
the back or bar of the fork.
Fig. 4. represents the blanks with slits e. e. from the perforations d. d. to the edge of
the blank, thus forming the portions f. f. to be drawn out into the prongs of the fork.
Fig. 5. shows the blank perforated in such a manner as to dispense with cutting
the slits e. e. separately.
The blank after being prepared as shown in Figs. 4. 7. is bent into a similar shape
to that represented by Fig. 6. to facilitate the drawing out of the portions f. f. into
prongs, one of which is shown drawn out at h.
We prefer to make the perforations as illustrated on the accompanying sheet of
drawings, but it is obvious they may be any size, shape, or number, without departing
from the principle of this invention.
Having now particularly ascertained the nature of our said invention, and in what
manner the same to be performed, we declare that what we claim is :
Forming blanks out of solid steel slabs with perforations or slits, so as to form the
parts required to be drawn out under a hammer, to make coke and other forks, sub-
stantially as hereinbefore specified, and illustrated on the accompanying sheet of
drawings.
