page_text: When the wedge is driven into the handle (as shown in figure 1) the nail is
inserted into the groove with its rounding side fitting against the rounding side of
the groove, so as to form a neat fit. The nail is then driven in and the incline H
will come against the incline F of the wedge and the lower edge of the nail is
deflected outward into the wood of the handle, as shown in figure 1, thereby
securely holding the wedge in place.
The principal object in having the groove D and nail G. semi-circular in
transverse section, is to avoid all danger of an inexperienced person driving the
nail into the wedge with the wrong side toward the back of the groove, it being
necessary that the incline H of the nail should bear against the incline F of the
'wedge.
If the groove and nail were square with one edge of the latter bevelled, at H,
and the nail were to be driven down with this bevel turned towards the back of
the groove, the deflection of the inner edge of the nail (as shown in figure 1) would
not take place.
By shaping these parts, as I have shown and described, they will only fit
together in their proper positions and therefore all danger above mentioned is
avoided.
The wedge is preferably provided with a raised central portion I, upon which to
strike in driving the wedge so that the main part of the wedge is driven beneath
the surface of the hammer,
The outer edges of the wedge may be provided with lugs J (shown in figure 5)
which would extend beyond the eye of the hammer to still further prevent the head
from coming off the handle.
My improved wedge can be quickly and cheaply produced, is effectuel in per-
forming its functions and avoids all danger of the hammer being lost and can be
easily applied by any inexperienced person.
In figures 6 and 7, I have shown, instead of the groove in one side of the wedge,
a hole or holes L extending downwardly through the central part of the wedge and
baving openings at ita or their lower lower ends, through which the lower end of
the nail would protrude and extend out into the wood of the handle, as shown in
figure 1; the lower end of the hole being inclined, as shown at M, so as to deflect
the lower ends of the nails. In figure 6 I have shown one hole only in the middle,
and in figure 7 I have shown two holes, one near each edge of the wedge. With
this form of wedge a round nail would be used.
In figures 8, 9 and 10, I have shown another modification of my preferred form
a groove or grooves N on each side of the wedge, (provided with inclines N' at
their lower ends) to receive a staple O, shown in figures 8 and 11; the inclines
acting to turn out the ends of the staple into the wood, as shown in figure 8. The
staple may bo serrated or roughened on its outer edges if desired.
In figure 9 I have shown one pair of grooves near the center of the wedge, and
in figure 10 two pairs of grooves one pair near each edge of the wedge.
In figure 12 I have shown a cap P that fits on the end of the hammer handle,
and which is retained by a head 1, on the wedge, as shown in figures 8 and 9.
While I have shown and described my improvements in connection with a
hammer, it is evident that they may be applied to other things, as for instance,
axes, picks and all kinds of tools; and they may also be applied in certain
instances to secure together parts of furniture.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination of the wedge and nail, the wedge being made in ona part
with a groove or opening, and an incline at the lower end of the groove or opening,
and the nail securing said wedge in the handle, substantially as set forth.
2. In combination with a hammer or other tool or article having an eye there-
through and a handle inserted in said eye of a grooved wedge driven into the

page_text: handle and a nail inserted in said groove substantially as and for the purpose set
forth.
3. In combination with a grooved wedge and nail the wedge being made in one
part with an opening at the lower end of the groove the bottom of the opening
being inclined and the nail having an inclined surface substantially as shown and
described for the purpose set forth.
4. The combination of the wedge and nail the wedge having a groove semi-
circular in shape in transverse section and an opening at the lower end of the
groove with an incline F and the nail being semi-circular in transverse section and
having an incline H at its lower end substantially as and for the purpose set forth.
5. The combination of the wedge having a groove D, opening F and projection I,
the opening F being inclined at its bottom and the nail provided with an inclined
inner end, substantially as and for the purpose set forth.
