I ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex
Engineer, do hereby declare the nature of this Invention for "IMPROVEMENTS IN
THE METHOD AND MEANS FOR ATTACHING WOODEN HANDLES TO TOOLS HAVING
AN EYE OR APERTURE OPEN AT BOTH ENDS FOR THE RECEPTION OF SUCH
HANDLE 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 my improvement is to provide a simple and efficient means of
attachment of a hammer or mallet head upon its handle; and to this end it consists
in the combination, with the head and handle, of peculiarly constructed wedges or
fastening devices, substantially as hereinafter more fully set forth.
Fig. 1 is a section and Fig. 2 a plan view showing one method of attaching a
hammer or mallet head to its handle and Figures 3 and 4 are the wedges employed
for this purpose; Figure 5 is an elevation and Figures 6 and 7 are sections of a
hammer head and Figure 8 is a like view of a head and handle showing another
method of attaching the head to the handle; and Figures 9, 10 and 11 show the
wedges here employed; Figures 12, 13 and 14 show by sections still another
method of attaching the hammer head to its handle; and Figures 15 and 16 show
the wedges.
The fastening devices or wedges employed to secure the hammer or mallet head
to its handle may be constructed in different forms without departing from the
spirit of this Invention and its object which as above stated, is to provide a secure
attachment of the head to the handle. For instance in Figs. 1, 2 and 3 is shown a
hammer-head A (which may be of any desired size or form) that has a cylindrical
aperture B, for the reception of the handle C. The eye or aperture B, (as shown
in Figures 1 and 2) has two grooves b, opposite to one another, and the handle C
has an annular groove c, which when the handle is inserted into its eye, will be in
a line with the rounded lower ends a of the grooves, b b in the hammer head, which

page_text: said grooves or recesses extend only about two-thirds down into the head, as will
be seen by reference to said Figure 3. The wedge D, employed in this form of
attachment, as shown in Figures 3 and 4, has one end, d, Lent or hooked to form
the notch d¹ one such wedge being used on opposite sides of the handle end.
Each wedge being somewhat longer than the depth of the groove b, into which it
is inserted. On the right side of the hammer handle, Fig. 3 is shown the wedge D,
as it appears when inserted into its appropriate groove b, and before it is rammed
down, while on the opposite or left hand side is shown the wedge after it has been
rammed down with its top flush with the hammer-head. In this process of ramming
down the wedge D, its notched and hooked end d, will by the rounded bottom a,
of the groove b be driven into the wood of the handle at the annulus, c, the notch d¹
operating to facilitate the bending of the hooked end, which will fasten it and the
hammer head firmly upon the handle so that it cannot by any possibility fly off.
The annular groove or channel c in the handle may be dispensed with, as the
hooked and pointed ends of the wedges will work into the wood without it. Where
the wedges D are to be used with a wooden mallet-head it is preferrable to construct
them with a projecting spur d³, as shown in Fig. 4, which, in driving the wedge
home into its recess, will work into the wood of the head at the same time that
the point d, works into the wood of the handle. In Figs. 5, 6, 7, and 8 the
hammer-head has a conical eye B, and the handle is attached hereto by means of
three wedges, D D¹ and D². The handle C is cylindrical and is made to take the
shape of the hammer-eye by first forcing in the wedge D, Fig. 9; then by the side
thereof the wedge D1 Fig. 10; and between the two the wedge D2, Fig. 11. The
wedges D and D¹ have on their outer faces spurs, d³, that penetrate into the wood
of the handle and prevent their retraction and when the wedge D1, is driven home
it rests upon a ledge d' formed upon wedge D, which has also a slot, d' on a line
with said ledge through which passes the sharp lip de of the spreading wedge D*,
when the latter is driven home, said lip penetrating into the wood of the handle,
and bent, as shown in Fig. 8, locks the wedges securely together and to the handle C,
as will be readily understood, and the eye B, if desired, may be provided with
teeth, b² as shown in Fig. 7 for obvious reasons.
In Figs. 12, 13, 14 and 15 is shown a further modification of construction of
wedges. That shown in Figs. 12 and 15 has two projecting d' and d³, beveled
upon reverse faces so that when the wedge is driven home into the handle the two
prongs will spread laterally in opposite directions and the lower end thereof will
be bent, as shown in Fig. 12 performing the same functions as the wedges herein-
before described and serving a like purpose. The wedge shown in Figures 13 and
16 has one prong, d upon one side, and in its opposite side is formed a prismatic
groove do for the reception of a second prong 8, that has a prismatic forin adapted
to fit into said groove. As will be seen, the second prong d³, in this case is
removable and is driven home after the wedge D is in position in the hammer
handle.
The driving home of this wedge will also bend its lower pointed or sharp end
and prevent its retraction, while it holds the wedge securely in position by jamming
as will be readily understood said wedge being besides held against vertical move-
ment by the bending of its prong d when the wedge is driven into the handle.
In Fig. 14 is shown a plain wedge D held in position by two headed prongs D³ the
heads of which when driven home will be one above the other upon the upper face
of the wedge. This last described method is well adapted for securing very small
hammer-heads to their handles and if the hammer-head is sufficiently large to
permit of the use of a sufficiently broad wedge the prongs may be driven into the
handle, so that their heads will be side by side and prongs may be used in
conjunction with either of the wedges shown in Figs. 15 and 16.
Of course it will be understood that the Invention is not limited to the use of
the form of wedges shown and described as these may be varied infinitely without
departing from the nature of this Invention, though it has been found that the

page_text: construction of wedges shown and described are well adapted for the purpose for
which they are intended, and may be used in conjunction with any other tool or
implement having a separate handle fitted into an eye that is open at both ends.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I claim
