PROVISIONAL SPECIFICATION..
An Improvement in the Shape of Bars of Iron, Steel, or any other
Substance, so as to Avoid Waste of Material in the Making of
Square, Hexagon, Octagon, Oblong, or any other Shape of Nut
Required.
FREDERICK ARTHUR MURPHY, 92, Belgrave Road, Oldham, Lancashire,
Engineer, do hereby declare the nature of this invention to be as follows:
My invention is intended to prevent waste of material in the manufacture of
nuts of various shapes and of any size and consists of bars of steel iron or any
other substance moulded or rolled flat of sufficient thickness to suit the thickness
of the nut requited. The two edges of the said bars to be serrated or indented at
regular intervals and directly opposite each other. The shape of the serrations or
indentations and the spaces between each will determine the shape and size of the
nuts required. These bars are intended for the making of square, hexagonal,
octagonal, oblong or any other shape of nut required.

FREDERICK ARTHUR MURPHY.
An Improvement in the Shape of Bars of Iron, Steel, or any other
Substance so as to Avoid Waste of Material in the Making of
Square, Hexagon, Octagon, Oblong, or any other Shape of Nut
⚫ Required.
I, FREDERICK ARTHUR MURPHY, of 92, Belgrave Road, Oldham, in the County
of Lancaster, 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:-
This invention relates to improvements in the construction of bars of iron,
steel or any other suitable metal capable of being rolled or cast and such as will
be suitable for use in the manufacture of square, hexagon, octagon, or other
shaped screw nuts used in connection with bolts, studs or the like for fastening
parts of machinery or other objects together, the object of the improvement being
to provide bars of any suitable length so formed that very little or no waste of
material will take place in the making of nut blanks, of the shape referred to,
from them.
To this end my invention consists essentially in rolling or moulding the bars

page_text: of iron, steel or the like from which the nuts are to be made of a thickness corre
sponding or nearly so, to that required in the rough or finished nut and in forming
the edges of the bars with serrations or indentations opposite each other at regular
intervals, preferably, though not necessarily, corresponding in shape to some of
the sides of the nuts to be made from the bars.
My invention will be fully described with reference to the accompanying
drawings which show several examples of bars made in accordance with my
improvements and in which
Figs. 1 and 2 show in plan and side elevation a bar arranged for the making
of hexagonal nuts,
Figs. 3 and 4 similar views differently arranged,
Figs. 5 and 6 bars for octagonal nuts,
Figs. 7 and 8 bars for square nuts and
Figs. 9 and 10 bars for diamond shaped or hexagonal nuts.
Figs. 11 to 18 show plans and elevations of bars arranged to produce circular
plates or nuts, hexagonal, octagonal, or square nuts, as will be readily understood.
In all the views the bar a, which may be of the usual commercial length, or
shorter, is made of a thickness corresponding more or less to that of the rough
or finished nuts to be produced therefrom and on each edge is indented at regular
intervals as at b. In Figs. 1 to 12 these indentations are of such a shape as to
correspond to the shape of some of the sides of the nuts to be manufactured there-
from so that little or no waste is produced in separating each nut from the other.
Thus in Figs. 1 and 2 and 5 and 6 very little waste is created when each nut
blank is separated from the other by punching and shearing or otherwise cutting
the bars across the dotted lines c, whilst in Figs. 3 and 4; and 8 and 11 and 12
only very little waste is produced also, that being the small fin or piece connect-
ing one nut blank to the other. Instead of the diamond shaped nuts shown in
Figs. 9 and 10, hexagonal nuts may be produced by cutting the bars across the
dotted line though in this case the outer triangular pieces would be wasted,
or they might be utilised in forming small triangular or other shaped nuts.
Figs. 13 to 18 the shape of nuts indicated by the dotted lines may be made from
circular blanks by cutting the portions outside the dotted lines away, but I prefer
the methods where least waste material is made. The bars may be rolled or cast
to the shape required by any suitable process.
In
By means of bars formed as described I can make nuts very rapidly and
without, or with very little, waste, and thus effect considerable economy over
the present methods of forming these.
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:-
1. In the making of screw nuts for bolts the use of continuous or commercial
bars of iron, steel or other material suitable for nuts, rolled or cast to the thick-
ness of the nuts required and serrated or indented at the edges at regular inter-
vals by rolling or moulding substantially as described.
2. Bars for making screw nuts for bolts and the like rolled or cast to the
shape described and shown with reference to either of the pairs of figures of the
accompanying drawings.
