Complete Specification Left, 28th Jan., 1891-Accepted, 21st Feb., 1891
PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Spades.
We, EDWARD ALBERT PEAKMAN, Commercial Traveller, and HENRY EDWIN
YATES, of the firm of John Yates and Company, Edge Tool Makers, all of
Pritchett Street, Birmingham, in the County of Warwick, do hereby declare the
nature of this invention to be as follows:-
==
This invention relates to improvements in the manufacture of spades, upon which
straps are formed for the securing thereto of the tree or stail, together with what is
known as a wedge tread, upon each side; and consists in providing in combination
therewith, a tread formed in the solid upon such spade.
Treads upon spades have already been formed in the solid where the tree has
been secured in a socket, but in such cases the spade at such part is simply one
plate, whereas, in spades where the securing of the trec, is effected by means of
straps, it is formed into (or by) two plates at such parts, between which the lower
end of the tree and the wedge treads, are passed.
Hitherto upon this kind of spade also, treads have been provided, but have been
attached thereto by rivetting, and these, in course of time, become loose, and very
troublesome. In this our invention this difficulty is completely overcome.
When making the said spade, those parts of the piece of metal from which it is
forged, which lie upon each side of the straps, is shaped, and then bent down at
right angles thereto, thus forming a solid tread in combination with the wedge tread
upon either side of the straps.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Spades.
We, EDWARD ALBERT PEAKMAN, Commercial Traveller, and HENRY EDWIN
YATES, of the firm of John Yates and Company, Edge Tool Makers, all of
Pritchett Street, Birmingham, in the County of Warwick, 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 manufacture of spades having
straps, by means of which the handle or tree is secured thereto together with what
is known as a wedge tread upon each side; and consists in providing in combination
therewith, a tread formed in the solid upon such spade.
Treads in the solid have already been formed upon spades where the tree has
been secured in a socket, but in such cases the spade at such part is simply one
plate, whereas, in spades where the securing of the tree is effected by means of
straps, it is formed into (or by) two plates at such parts, between which the lower
end of the tree and the wedge treads are passed.
Hitherto upon this kind of (straps) spade also treads have been provided, but
have been attached thereto by rivetting, and these in course of time become loose,
and very troublesome.

In this our invention this difficulty is completely overcome.
When making the said spade, those parts of the piece of metal from which it is
forged, which lie upon each side of the straps, is shaped, and then bent down at
right angles thereto, thus forming a solid tread in combination with the wedge
tread upon either side of the straps.

page_text: In order to more clearly explain this our invention we have appended hereunto
an illustrative sheet of drawings, upon which are figures and letters of reference,
similar letters referring throughout the several views to the same thing or part.
Fig. 1 shows the spade in its part wrought state.
Fig. 2 is a side view of Fig. 1.
Fig. 3 is n front view of the spade as finished.

Fig. 5 is a sectional plan view on line A-B.
That portion of the two plates from A to B and approximately within the
lines CD is not welded, but left so that the wedge tread (, as seen in Figs. 34
& 5, may be inserted.
That part of the plate from A to E, and 13 to F, is first shaped as seen in Fig. 1.
The part above the dotted line H-1, is then bent over as seen in Fig. 34 & 5,
forming the tread J, J.
The straps KK, handle or tree L, and spade M, is otherwise then finished as in
the ordinary manner.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
The combination in a spade M, with the straps K K, wedge trend G G, of the
solid treads J, J, substantially as described and shown.
