IMPROVEMENTS IN THE METHOD OF MANUFACTURING TROWELS, SHOE LIFTS AND SIMILAR ARTICLES
Year: 1884

page_text: JOHN DAWSON, Bernard Works Park Sheffield Manufacturer of Cutlery Materials
do hereby declare the nature of my invention for IMPROVEMENTS IN THE METHOD
OF MANUFACTURING TROWELS, SHOE LIFTS AND SIMILAR ARTICLES to be as
follows:-
First I take a piece of steel rolled the required breadth with a double bevil by
which means a ridge is left down the centre of any thickness that may be required,
the said strip after being cut the necessary length is put under a pair of eccentric
rolls and rolled at one end, which leaves the part so rolled in a perfectly flat state,
this blank is then placed under a stamp the required size and shape, which cuts out
the article and in consequence of the ridge left upon the unrolled part of the steel
a substance of any required thickness may be left to form a tang which can be
forged into any shape required.

I, JOHN DAWSON of Bernard Works Bernard Lane Park, Sheffield in the County
of Yorkshire manufacturer of Cutlery Materials do hereby declare the nature of
my invention for IMPROVEMENTS IN THE METHOD OF MANUFACTURING TROWELS
SHOE LIFTS AND SIMILAR ARTICLES and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:—
In place of taking a piece of steel rolled flat the required thickness and size as
now used I roll a string or sheet of steel the thickness in the centre required to
form the tang or socket, but on the edges thin enough to form the edge of the
blade, the width of the article required to be made, this string or sheet of steel may
be rolled either double bevil on one side see drawing A or on both sides see
drawing B, or with a cone in centre as drawing C and D, the said cone in the
centre of drawings C and D may be rolled round or any other shape according to
the pattern of the tang required to be formed.
The steel after being rolled into strings or sheets in the manner described is next
cut into the length required, the thick part in the centre is then heated and placed
under a pair of eccentric rolls but only put under so far as to reduce the part
required for the blade. to the thickness required see drawing E, the part intended to
form the tang has still the full thickness left as in the string or sheet, the tang is
next formed by cutting the sides away with a bed and punch leaving the article as
drawing F, the tang may then be forged into any shape and made still thicker
towards the centre if required, the blade is then sheared or stamped the shape
intended to be made as say drawing G and the tang turned as say drawing H. If
a socket is intended to be formed for a hoe or shovel the tang is stamped as
drawing I, then heated and turned round a punch as drawing J if thought desirable
the socket may be wrapped over and welded.
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. The method of making the tangs and blades of trowels, shoe lifts, shovels
hoes, and similar articles from one solid piece of steel by rolling the said steel in the
manner described, instead of a perfectly flat sheet or string as is now done.
2. The formation of the blades of the aforsaid articles, by eccentric rolling the
part required to be thinner than the tang, and by this means leaving the part to
form the tang the full strength of the steel as at first rolled.
3. The formation of a solid steel tang by stamping out pieces on each side and
afterwards forging the said tang to the size and thickness required.
4. The formation of a solid socket with greater strength of neck or shank in the
same manner.
