page_text: We ISAAC NASH, Junior, of Stourbridge Forge, Stourbridge, in the County of
Worcester, Spade and Shovel Manufacturer and JOHN LEWIS DUBOIS of 43 Lilles-
hall Road, Clapham in the County of Surrey, Agent 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 invention has reference to the manufacture of coal or other shovels with a
guard at the rear of the pan or blade. Hitherto this guard has been formed of a
separate piece of sheet metal, leather or other material the lower edge being turned
under the base of the pan and attached thereto by rivets.
Now according to this invention we make the guard by first forming and turning
up two horns from the metal sheet or piece of which the pan is made, these two
horns being respectively on the two sides of the socket or straps of the handle, and
by then attaching to the back of these horns by rivets or otherwise a piece of
leather, sheet metal or other suitable material which covers the space between the
horns and also forms a backing to them. In some cases, particularly when leather
is used, we interpose between the horns and the leather a piece of sheet metal to
cover the space between the horns and thereby protect the leather.
The annexed drawings serve to illustrate the invention. Figure 1 is a plan
representing the pan or blade of a coal shovel after it has been shaped and the
socket or straps have been formed, but before the two horns have been turned up
from the flat. Figure 2 is a plan, Figure 3 a front view and Figure 4 a central
longitudinal section of the finished shovel. a is the pan or blade, b the usual
socket or straps for the handle c. d d are the two horns formed from portions of
the same piece of metal as the pan. e is the piece of leather, sheet metal or other
material attached to the back of the horns and covering the space between them.
f is the piece of sheet metal interposed between the horns and the leather e to
protect the latter; this piece f is however not essential. The horns d d, piece e
and piece fare shown as attached together by rivets but other modes of attach-
ment, such for example as lashing may be employed.
The invention is applicable both to shovels in which the pan and the socket are
formed out of one piece of sheet metal and to those which are formed by hammering

shovels, such as that shown, but also to other shovels in which a guard is requisite
or desirable.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim, in respect of the manufacture of coal or other shovels, is :-
1. Making a guard by forming and turning up horns from the piece of metal of
which the pan or blade is made and then attaching to the back of such horns &
piece of leather, sheet metal or other suitable material, substantially as set forth.
2. The combination with the horns (dd) and piece of leather or other material (e)
of the piece of sheet metal (f) as set forth.
