I THOMAS NORRIS, of Woolaston Mills, Stourbridge, in the County of
Worcester, Edge Tool Manufacturer, do hereby declare the nature of my Invention
for "IMPROVEMENTS IN OR RELATING TO THE MANUFACTURE OF LANGETS, STRAPS,
OR SOCKETS, APPLICABLE TO FORKS, SPADES, AND OTHER SIMILAR ARTICLES," and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention consists of the improvements hereinafter described in the manu-
facture of langets, straps, or sockets, applicable to spades, shovels, forks, and other
similar articles.
By my invention the manufacture of the said parts is much simplified and
economised as the expense and labour of shaping or hammering from the bar or
strip of iron or steel is dispensed with and I produce a smoother and better finish
than by the olden mode of hammering.
I will describe my invention thus, I roll the iron or steel to the width and
thickness required, and of that shape or configuration suitable to the purpose, so
that certainty of strength will be left in the right place which has not been the
case hitherto. These may be of any length, guage or width, single or double, and
I make a rolled section for this purpose instead of what was formerly a hammered
one the expense of haminering and the waste of shearing or cutting to the required
width and length being done away with.
And in order that this my said invention may be more thoroughly understood
I will now proceed to describe the same by the aid of the accompanying drawings,
similar letters of reference denote similar parts in each figure in which they occur.
Fig. 1 is an edge view of shape made in the present manner.
Fig. 2: is a plan view of same shewing also superfluous metal.
Fig. 3 is an edge view of part of a series of straps rolled according to my
invention.
Fig. 4 is a piece of same broken or cut off from the long piece.
Fig. 5: is a plan of strap finished as far as necessary.
Fig. 6: is a section of a pair of rolls for rolling the straps.
Fig. 7: is a partial elevation of same.
Fig. 8: is a section of a roll for rolling three straps at each revolution.

a Figs. 1 and 2 is the strap as made by hammering, it will be seen that it is not
very regular in thickness nor is the thickened end a made very nearly. In Fig. 2
a represents the strap, and 6 61 62 63 the superfluous metal which is waste and has
to be removed by shearing according to the dotted lines. c Figs. 3. 4. 5 shews the
strap or straps of metal rolled according to my invention, a flat bar of iron or steel
is made red hot and being passed between pairs of suitably shaped revolving rolls
(as Figs. 6. 7.) the thickened pieces c¹, c¹, are formed accurately, and the rest of the
strip is also made of the required width and thickness. The whole length of the
bar may be rolled into a series of straps as shewn in Fig. 3. each strap is then
cut or broken off at the points g, g, the line g, g, shews the length of each strap.
The strap then is of the shape shewn in Fig. 4, it is then only needful to shear
off the corners c² c³, as shewn by the dotted lines, and the strap is complete so far
as relates to my invention.
The rolls by which the foregoing is effected are shewn in

the shaping to the roll d, I do not confine myself to the exact shape of the parts
shewn on my drawing. I am aware that somewhat similar rolls to those here
described have been used for rolling iron or steel for special purposes, such as nails,
fang-nuts.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st An improved method of forming langets straps or sockets of forks spades
or other similar tools by rolling instead of by hammering as hereinbefore described.
Second. The application of rollers having proper grooves or indentations whereby
the metal passed through them is formed into suitable shape for the straps used in
making langets or sockets for spades forks and other similar tools..
Third. The construction and combination of parts as shewn on the accompanying
drawing and described in this specification for rolling metal into shapes suitable
for langets straps or sockets, forks, spades, and other similar tools.
