We, THE WILKINSON SWORD COMPANY LIMITED, of Oakley Works, Kings Road,
Chelsea, in the County of London, do hereby declare the nature of this invention
(as communicated to us from abroad by Julius Weiss of Hamburg, Germany,
Architect) to be as follows:-
This invention has for its object to effectually secure the loops or eyes of axes,
hammers and other tools to their handles without requiring to form the holes of
the loops conical or tapering as heretofore, the fastening being such that the tool
cannot fly off and that even in the event of the handle shrinking through drying,
the tool will be securely held thereon,
The invention consists in the employment of three metal wedges or keys of
peculiar form, which are driven into the part of the handle within the loop of
the tool as follows: In the end of the handle are formed three parallel saw cuts
before it is fitted into the eye of the tool.
Into the middle cut is then driven a thin flat wedge swelled in thickness or
fish-bellied at the inner part and provided with an enlargement or head with
bevelled sides which projects from the end face of the handle. Into each of the
side cuts are then driven two shorter wedges identical in form being also swelled
out at the middle on the side facing the middle wedge while the other side is
formed with serrations.
By means of these three wedges the wood of the handle is expanded so as to
be tightly fixed in the loop of the tool. Should the wood shrink so as to cause
a slipping of the tool, the middle wedge is seized by its projecting head and is
drawn slightly outwards.
By this means the enlarged part of this wedge is drawn nearer to the enlarged
parts of the two side wedges, and in thus spreading them and the surrounding
wood laterally it effects the tightening of the handle in the eye of the tool again.
Although as above stated, the invention does away with the necessity for
tapered loops or eyes, yet it is of course applicable with equal advantage to tools
having tapered eyes.

described and ascertained in and by the following statement:-
-
This invention has for its object to effectually secure the loops or eyes of axes,
hammer and other tools to their handles without requiring to form the holes
of the loops conical or tapering as heretofore, the fastening being such that the
tool cannot fly off and that even in the event of the handle shrinking through.
drying, the tool will be securely held thereon.
The invention consists in the employment of three metal wedges or keys of
peculiar form which are driven into the part of the handle within the loop of the
tool as we will describe with reference to the accompanying drawing, in which
Figs. 1 and 2 shew respectively a side and end view of an axe handle with the
invention applied thereto; Fig. 3 shews a front view, Fig. 4 and end view, and Fig. 5
a top view of the middle wedge a; Figs. 6 and 7 shew respectively an end view
and front view of the side wedges b. Fig. 8 shews the axe handle prepared to
receive the wedges.
In the end of the handle are formed three parallel saw cuts S S¹ 8 before it is
fitted into the eye of the tool. Into the middle cut is then driven the wedge a
which is swelled in thickness or fish bellied at the inner part, and is provided with
an enlargement or head k, with bevilled sides that projects laterally over the eye
of the tool as shewn at Fig. 2. Into each of the side cuts are then driven the two
shorter wedges of identical form, being also preferably swelled out near the
middle, the sides away from the wedge a being formed with serrations as shewn.
By means of these three wedges the wood of the handle is expanded so as to be
tightly fixed in the loop of the tool. Should the wood shrink so that the eye of
the tool could slip outward thereon, such slip could only take place in drawing
the middle wedge outwards by its head and by such drawing outwards the en-
larged part of this wedge would be drawn nearer to the enlarged parts of the
wedges and it would thus be made to force these laterally outwards, thereby
expanding the wood, and effectually tightening it in the eye of the tool again.
Although as above stated, the invention does away with the necessity for tapered
loops or eyes, yet it is of course applicable with equal advantage to tools having
tapered eyes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
Appliance for securing tools on their handles consisting of the combination of
three wedges such as a, b b driven into the handle, of which wedges the middle
one a is formed fish bellied and has a head projecting over the eye of the tool, so
that on the latter slipping outward on the handle, it would draw the wedge a cut-
ward and thus expand the handle in the eye, substantially as described.
