PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Coke and similar Forks.
I, GEORGE WIlliam ElliotT, of Meersbrook Park Road, Heeley, Sheffield
in the County of York, Mining and Mechanical Engineer do hereby declare the
nature of this invention to be as follows:-
An improved method or manner of constructing coke and similar forks, by
which invention the blades or prongs, are made detachable and separate.
The cross bar which carries and connects the blades or prongs, 1 make of
suitable metal or material, of the required length and strength, and which consists
of a greater or less number of sockets, recesses or pockets, at approved distances
apart, for the reception of the thicker end of the blade or prong. These sockets
are joined or connected together by a horizontal and vertical web or webs of which
the said sockets form part of, and are solid with. The sockets may be of
rectangular or other shape to suit the section of material used in making the
prongs.
The bar formed by and composed of the said sockets and webs combined is
provided, on the opposite side to that from which the prongs project, with a curved
or straight shank to which the handle may be attached and scoured.
One form of shank I adopt resembles in a cross section the letter Ţ, being
formed of or by a central and vertical web, having across its upper edge, and
combined with it, a cross bar of approved sectional design, or the shank may be
made of circular or tubular section, thus forming a simple socket into which tho
handle is driven.
The cross bar is also provided with holes, formed in, at right angles with and
through, the said sockets, rectangular or otherwise in shape, and that portion of
prong which enters the socket is provided with a saw gate or groove of suitablo
width and depth, and a small pin or cotter pressed or driven into the hole in cross
bar and thence through and into the groove in the prong secures the same in
position.
By another method I adopt in securing the prong in position the said blado or
prong is formed having a recessed part or portion of the same length as the
socket, and drive one or more wedges or cotters between, parallel, and in line with,
prong or blade, and the side of socket.
These sockets, and the thicker ends of the blades or prongs which fit into each
other may be made parallel or tapered as may be found most advantageous.
One special feature of this invention is that in forming the small cotter or pin
holes in the cross bar, I may employ metallic cores, in lieu of, or combined with
sand, painted or covered with suitable material.
By adopting this method of forming the before mentioned cotter or pin holes
much greater accuracy and sounder castings are obtainable, and I avoid all danger
of the said cotter or pin hole cores being moved or carried away during the process
of casting the said cross bar.

Improvements in the Manufacture of Coke and similar Forks.
I, GEORGE WILLIAM ELLIOTT of Meersbrook Park Road, Heeley, Sheffield,
in the County of York Mining and Mechanical Engineer 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 :—
An improved method or manner of constructing coke and similar forks by
which invention, tho blades or prongs are made detachable and separate.
The accompanying sheet of drawings, in which same letters of reference apply
to and indicate similar parts or details in the various figures, will illustrate the
modes or methods 1 preferably adopt in making or constructing forks according to
iny improvement.
Figures 1, 2 and 3, represent a sectional elevation, plan and end view, respectively
of a fork, having, or constructed with a cross bar A, consisting of a greater or less
number of sockets, recesses or pockets C for the reception of the thicker end B',
of the prong or blade B, joined or connected together by a bar formed of a
.horizontal and vertical web or webs D, of which the said sockets C, form part of
and are solid with, the whole being made of suitable material, of the required
length and strength.
The sockets or pockata C may be of rectangular or approved shape to suit the
section of material used in making the prongs or blades B.
The bar A, formed by, and composed of, the sockets C, and webs, horizontal and
vertical D, combined, is provided on the opposite sido to that from which the
prongs or blades B, projcot, with a curved or straight shank E, to which the
handle F, may be attached and secured.
One form of shank I adopt, and which is shown on drawings, resembles in a
cross section the letter T being formed by a central and vertical web E', having
across its upper edge, and combined with it, a bar (curved) E, of approved
sectional design, or the shank may be made of circular or tubular section, thus
forming a simple socket into which the handle F may be driven.
In the cross bar A, at right angles with, and through the sockets C, I form
holes H, rectangular or otherwise, and in that portion of the prong B², which
enters the socket C I also form or provide a groove or sawgate H¹.
To secure the blade or prong B, firmly in position a pin or cotter K, is pressed
or driven into the hole H, in cross bar A, engaging with, and passing through the
groove or sawgate H', in thick end B', of blade or prong B.
In Figures 2 and 3, two kinds or sections of blades or prongs B, are shown,
together in position with two methods of fastening or securing the same, which aro
also shewn or illustrated on an enlarged scale by Figures 6 and 7.
Figures 4 and 5 are also enlarged views of the sockots C, and prong or blade
ends B', shewing different sections and methods of attaching or securing the prongs
in position.
By the methods illustrated by Fig. 7 I form the prong or blade end B³, having
a recessed part L of the same length as the socket C, and of the requisite depth,
and secure the said prong in place by driving one or more wedges or cotters K,
between parallel, and in line with the prong end B' and side of Booket C.
The sockets C, and the thicker ends B³, of the prongs B, may be made 'taper
or parallel as may be found most advantageous.
I do not confine myself to the configurations or designs shewn on drawings, but
which will be found sufficient to illustrato and explain the principle of my invention,
one feature of which is, that in forming the small pin or cotter holes H, in the
cross bar A, I may employ metallic cores, in lieu of, or combined with, sand or
other material, painted or covered, or otherwise.
By adopting this method of forming the before-mentioned cotter or pin holes,
much greater accuracy and sounder castings are obtainable, and I avoid all danger

tion, and in what manner the same is to be performed I declare that what I
claim is
CLAIMS.
1st. Coke and similar forks, constructed with and having separate and detachable
blades, or prongs, secured to a cross bar, having one or more suitable sockets, by
means of wedges, cotters, or their equivalents, or a combination of such, sub-
stantially as herein described and illustrated on drawinge.
2nd. In the construction of coke and similar forks, the use of metallic cores, in
lieu of or combined with, sand or other material in the formation of small holes,
substantially as and for the purpose or purposes, herein described.
