"Improvements in Fastenings for the Handles of Picks and other
Tools."
I, ROBERT GRAHAM BURLEY, of 260, Paisley Road, West, in the County of
Renfrew, North Britain, Timber Merchant, 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:-that is to say:-
My said Invention has for its object to improve the construction of the fasten-
ings employed for fixing handles to picks and other tools.
I employ a metal sheath which is fixed on and strengthens the handle end, and
which is entered into the eye of the pick or other tool; I however construct the
sheath in an improved manner and as represented on an accompanying sheet of
explanatory drawings which are hereinafter referred to in describing my
improvements.
Figure, 1, of the drawings is a sectional elevation and figure, 2, is a section as
at right angles to figure, 1, showing one modification of my improved fastening.
Figures 3, and 4, are similar views of a second modification, and figures, 5, and 6,
are similar views of a third modification; whilst figures, 7, 8, and 9, represent a
fourth modification. In these drawings the same reference letters are used to
mark the same or like parts wherever they are repeated.
In the modification shown in figures, 1, and 2, the sheath, A., is made with its
interior tapering so as to be slightly narrower at its outer end; and it is driven
upon
the end of the handle, B, which requires to be only approximately shaped to
fit in the sheath. Each side of the sheath, A, is made with a tongue, C, having
one or more pointed projections, D, on its inner side; the tongues being bent a
little outwards as shown in figure, 2, before placing the sheath on the handle end,
but being afterwards flattened or bended inwards to fix the sheath on the handle
end. The sheath may be formed with internal grooves, E, which lighten the
metal, and into which the wood of the handle can spring out after being compressed
by driving on the sheath. The sides of the sheath, A, and tongues, C, may be
fluted or otherwise roughened externally. The outer part of the sheath, A, which
has to fit in the eye, F, of the pick is made with a taper opposite to the internal
taper, and the handle with the sheath, A, fixed on it having been entered from the
outer side through the eye of the pick, the external taper of the sheath which fits
a counter-part taper in the eye of the pick, prevents the pick from becoming
detached. The sheath may be made of malleable-castiron or other suitable metal.
The second modification (figures, 3, and 4) differs from the first in the form of
the tongues, C, and openings in the sides of the sheath, A, these openings being
within the outer parts of the sheath which parts remain entire or undivided.
In the third modification (figures, 5, and 6) the tongues, C, extend to the outer
edge of the sheath, A, as do also the slits at the sides of the tongues.
In the fourth modification (figures, 7, 8, and 9) the sheath, A, is not itself made
with a reversed external taper, but has such taper given by a pair of separato
shells, G, one of which is shown in edge view in figure, 8, and in section in

page_text: figure, 9. Each shell is made with an internal rib, H, which engages in a groove
formed for it in the outside of the sheath, A.
Having now particularly described and ascertained the nature of my said In-
vention and in what manner the same is to be performed, declare that what I
claim is:-
The improved fastening for the handle of a pick or other tool, consisting of a
metal sheath made with an internal taper narrowing outwards to fix on the handle
end and with tongues having internal pointed projections to be flattened or bended
in upon the handle end, together with a reversed external taper to fit the eye of
the pick or other tool substantially as herein before described with reference to
the accompanying drawings.
