COMPLETE DEMUIFICATION.
An Improved Brush Hook or Bill Hook.
We, HAROLD JAMES AUGUSTUS PYKE, of Customs Street, Auckland, Inventor,
and ARTHUR EDMONDS, also of Customs Street, Auckland, Kauri Gum Merchant,
both in the Colony of New Zealand, do hereby declare the nature of our invention
for "AN IMPROVED BRUSH HOOK OR BILL HOOK" and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
Our invention is designed to obviate some defects incidental to the present forms
of brush hooks.
Referring to the accompanying sheet of drawings in which
Fig. 1 illustrates our invention and shows in perspective the blade of our brush
hook and the means by which the handle (shown in dotted lines) is secured thereto
it will be seen that there are two novel features.
A represents the blade, having at the back a groove B which extends from the
handle end C of the blade longitudinally forward a sufficient distance to receive the
straight end portion of the helve,-D to E in the drawing. The groove is V shaped
in transverse section so that the lower edge of the helve may fit closely into it.
The said groove constitutes our first improvement.
F is a fixed metal collar or loop rivetted at G to the blade and of such form and
size as to be adapted to exactly fit over the end of the handle when the latter is
pushed home in its slot B as shown by dotted lines.
H is a metal brace or loop rivetted to the end of the knife blade as shown at I
and adapted to be opened or closed at its upper end K as may be required.
This brace is as shown in two parts, the upper ends H, H", are bent so as when
pressed together to make firm contact at such part and the body part is of curved
form and of such size that when the ends H, H" are secured together the body of
the brace will be adapted to grip closely the handle in the position indicated in the
drawing that is behind the shoulder L.
Any suitable means for locking the ends H¹, H" together may be used for
example the bolt and nut shown. By this means the handle can be gripped as
tightly as may be desired and shrinkage and wear on the handle can be prevented
from causing any looseness.
The bolt which secures the brace H is short so that it does not project objection-
ably on each side, and being at the back does not hinder the knife blade from
cleaving through the obstacles it is intended to overcome. This adjustable brace H
constitutes the second part of our invention.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In an improved brush hook, the herein described groove at the back of the
blade, said groove being adapted to receive the helve substantially as described and
illustrated in the drawings.
2. In an improved brush hook the herein described adjustable brace H rivetted
to the blade and adapted to be opened or closed as required substantially as and for
the purposes set forth.
3. In an improved brush hook the general combination and arrangement with the

page_text: blade of the hook, of a groove as B and braces as F and H whereby the handle
may be firmly secured to the blade substantially set forth.
