Complete Specification Left, 27th June, 1891-Accepted, 1st Aug., 1891
PROVISIONAL SPECIFICATION.
Improvements in Spades and Shovels.
I, PETER CALDWELL the Younger, of Lower Walton near Warrington in the
County of Lancaster, Spade Manufacturer, do hereby declare the nature of this
invention to be as follows:-
:―
This invention relates to all kinds of langet or strapped spades and shovels and
it has for its object to enable the spade or shovel and its straps to be manufactured
without a weld; it has further for its objects to enable the cofer or opening in the
blade to be dispensed with and to obviate the necessity for employing wedge-wood
and rivets in the blade.
In carrying out my invention I forge or otherwise produce a blank having a tang
thereon, the shape and dimensions of the blank and tang both being governed by
the shape and dimensions of the required spade or shovel. The tang is then sawn
or slit and the blade and straps are forged and shaped to the required form.
If the spade is required to be provided with a tread, this is also forged from
the solid blade so that there is no weld or joint of any kind in the spades and
straps.
Dated this 26th day of August A.D. 1890.

COMPLETE SPECIFICATION.
Improvements in Spades and Shovels.
I, PETER CALDWELL the Younger, of Lower Walton near Warrington in the
County of Lancaster, Spade Manufacturer, 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 all kinds of langet or strapped spades and shovels and
its objects are to enable the spade or shovel to be manufactured without welding,
and also to enable the "cofer" or opening in the blade to be dispensed with and
thus to obviate the necessity for employing wedge-wood and rivets in the blade.
In carrying out my invention I forge cut or otherwise similarly produce a blank
having a tang thereon, the shape and dimensions of the blank and tang being
determined by the shape and dimensions of the required spade or shovel. The tang
on the blank is then sawn or slit and the blade and straps are forged and shaped
from the solid to the required form.
If the spade be required to be provided with a tread, this is also forged from
the solid blade so that there is no weld or other joint between the blade and tread
or in any part and it is impossible for the tread to be forced off the blade.
I will more particularly describe my said invention with reference to the accom-
panying drawings in which
Figures 1, 2, 3, and 4 represent the spade or shovel in various stages of
manufacture; and
Figure 5 a completed and handled spade constructed according to these
improvements.
Figure 1 shews the rough blank, of which the part A will form the blade of the
future spade or shovel and the tang or part B the straps. As shewn in Figure 2
which represents the following stage of manufacture, the tang B has been cut or
slit longitudinally down to the blade for the purpose of producing the two straps.

.
For the purpose of cutting the tang, a saw may be employed such for example as is
used in cutting off rail ends. The blank is now forged or otherwise formed by the
usual means to the approximate form of the spade or shovel required as indicated,
the upper middle part, E.or the whole of the central and upper part, of the blade
being left thicker than the remainder of the blade to such an extent as may be
desired and, for example, as indicated at C. The blade is then cut to the finished
dimensions as shewn in Figure 4. Before the .blade is cut (or afterwards if
desired), the straps Dare forged or drawn out of the, divided tang upon a suitable
- former or, tool.
'
•
When the spade is required to be provided with a tread, such as F-Figure.5,.the
upper ends of the solid blade are hammered or forged over on each side so, as to
form the tread during the process of manufacture.
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 herein before 'described method of manufacturing langet or strapped
spades and shovels in one piece; substantially as and for the purpose set forth and
as illustrated by the accompanying drawings.
2. Strapped and langet spades and shovels constructed with solid blades and with
the straps in one piece with the blade substantially as hereinbefore described with
reference to the accompanying drawings.
