I, CHARLES PECK HAWLEY of No. 510, West 153rd Street New York in the
County and State of New York, United States of America, Inventor, 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 :-
The object of this invention is to improve the construction of ferrules and like
articles, such as barrel hoops, caps for canes, clamp rings for spars and the like, and
the eyes of axes, hammers, etc; and the invention consists in so ridging or serrating
the inner surface or bore of such forrule, cap, band, or eye, that a firm fastening of
either or any of them to the article to which they are applied will be assured, as
hereinafter described and claimed.
Reference is to be had to the accompanying drawing forming part of this specifi-
cation, in which figure 1 is an elevation partly in section, of a tool handle the ferrule
of which is formed in accordance with my invention. Figure 2 is a like view of an
axe the eye of which is formed in accordance with my invention. Figure 3 represents
a barrel hoop embodying my invention. Figure 4 illustrates a clamp ring for spars
and the like, the serrations being indicated by dotted lines. Figure 5 represents the

invention as applied to the cap and ferrule of a cane.
indicate corresponding parts in all the figures.
As the invention is the same as embodied in all the articles to which I have shewn
it as applied, a detailed description of one instance of its application will suffice.
Referring specially to figure 1 of the drawing, the inner surface of the ferrule A
of a tool handle B, is formed with a series of parallel notches a, each notch being cut
into the ferrule in a manner to form the inclined faces 6 and a series of shoulders c
which shoulders preferably range at right angles to the bore of the ferrule.
With this construction, as the ferrule or other eye or band, is forced on to the
handle or other object the inclined sides or faces b of the several notches successively
force inwards the fibres of the wood, which fibres have a tendency to wedge them-
selves into said notches as the ferrule band or eye is being driven home. When the

page_text: ferrule is fully driven home, the fibres having expanded into the notches a firmly hold
the ferrule in place, as the shoulders c thereon prevent return movement of the said
ferrule by resistance against the fibres of the wood which fill the notches a, and only
by a force sufficient to lacerate the fibres can the ferrule be removed. Even should
the wood of the handle, barrel, or other object, shrink after the ferrule, band, or eye
has been applied, the said ferrule, band, or eye, will not become displaced, as no
ordinary shrinkage will effect the full withdrawal of the fibres from the notches.
In previous attempts in this direction, the article, such as the eye of an axe or
hammer, has been formed with pins or spurs projecting at approximately right angles
to the said eye, but in such cases a wedge was required to force the handle against
the spurs to be penetrated thereby. Ferrules also have been formed with internal
screw threads, but the slightest shrinkage allows the ferrule to unscrew from the
handle or other object to which it may be applied. With my invention, the forcing
on of the ferrule or like eye or band, forces the fibres of the handle or other object
inward and the expansion of the fibres into the notches, holds it in place even after
shrinkage and without the aid of separate wedges.
My Invention will be found very advantageous as applied to the hoops of barrels
for containing spirituous liquors, where nails cannot be employed to secure the hoops.
The Invention is also applicable to ferrules, bands, or eyes of polygonal cross section,
which is not the case with spiral serrations.
The axe C, hoop D, clamp band E, and cane cap and ferrule F, G, are provided with
notches corresponding to those in the ferrule A of tool handle B.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A ferrule or like article, constructed with parallel internal notches a, the said
notches being formed to produce the inclined faces and parallel resistance shoulders c
at right angles to the axis of the ferrule, substantially as and for the purpose
specified.
2. As a new article of manufacture, a ferrule or like band or eye having parallel
serrations in its inner surface, substantially as and for the purpose specified.
3. A ferrule or like article, constructed substantially as herein shewn and
described.
