Application May 15, 1936, Serial No. 79,952
6 Claims. (01. 306-33)
My invention relates to a wedge and I declare
the following to be a full, clear, concise and eXact description thereof. suf?cient to enable anyone skilled in the art to which it appertains to
5 make and use the same, reference being had to
the accompanying drawing in which like reference characters refer to like parts throughout the
speci?cation.
The object of the invention is to provide a
10 wedge for use more. particularly in securing hammer or axe heads to their respective handles.
bottom edge 3 toward the top surface 2. The
taper, however, is acute at about midway between
the bottom edge 3 and‘ top surface 2, whereby
said wings 5, 5 disappear or terminate at said
central locations. By thus terminating wings 5, 5
5 below the top surface 2 of portion I said wings
5, 5 will disappear in wood ll of the handle l2
when driven home therein to secure the head
Hi to said handle I2.
Furthermore, the taper of central portion l 10

tools has caused the wedges heretofore used to
work loose and thereby allow the head of the

wings 5, 5 into handle l2, to be closed behind
15 hammer or of the axe to separate from its handle
and this perhaps at a time when the hammer
or axe is being swung to drive home a nail or
in the case of the axe to split wood with accompanying fatalities. The present Wedge over20 comes these difficulties as will be seen from the

them as they disappear below the upper surface 15
it‘ of the end of handle l2. This disappearance
of the wings 5, 5 into the Wood H of handle ii
and the closing of the openings behind them
positively locks the wedge l into the grain of said
wood ll within the eye or opening I‘! of the tool 20
l8, whereby the shock incident to the use of the

and fall out.

Referring more particularly to the invention,
the wedge consists of a rectangular portion I that
40 tapers from its top surface 2 towards its bot- ,
tom edge 3 in cross section. There is formed
integral however, on the opposite sides of the
rectangular portion l and. at its opposite lateral
edges, wings 5, 5 by curving the extended part
45 of rectangular central portion l at its opposite
lateral edges 6, 6 and in dilierent directions,
around back upon itself to form additional retaining surfaces. However, each of the wings 5 is
spaced from the adjacent surface of central por-
50 tion I.
.
These curved portlons 5, 5 do not lay quite
parallel Wlth the contiguous opposite lateral surfaces of portion l but incline or taper at their
_ free ends H], In towards said respective surfaces.
05
Moreover. said wines 5. 5 also taper from the
the added advantage of effecting a lateral wedge
on either side of central portion I. These lateral
wedges function as the Wedge is driven into posi
tion into that portion of wood ll of . handle I2
within eye ll of tool l8 which causes the free 35
points of wings 5, 5 to be forced outwardly thus
effecting lateral Wedges on opposite sides of part '
l in addition to the wed‘gl'ng 0f Said Central Por
tion I.
As a further means of holding wedge I into 40
position when driven home into that portion of
wood ll of handle l2 within eye ll of tool Is,
the free edges of wings 5, 5 are notched or formed
with barbs 20 which slide easily into wood I l of
handle IE but do not allow said wedge l to be 45
pulled out of said handle l2.
Having thus described my invention what I
claim as new and desire to secure by Letters Pat
ent is as follows:
1. In a wedge, a central portion tapered from
one end to the other, wings formed on said cen
tral portion, said wings terminating midway be
tween the upper and 10wer edges or the wedge
and disposed on opposite sides thereof, whereby
to effect additional retaining members. '

2. In a wedge, a central portion tapered from
one end to the other, Wings formed on opposite
sides of said tapered portion and at opposite ends
thereof said wings tapering towards said central
portion and said wings terminating midway be
tween the upper and lower edges of the Wedge,
whereby to effect additional wedging functions.
3. In a wedge having a central portion that
tapers in cross section from one end to the other,
wing members formed on said central portion,
10 said wing members lying in spaced relation to
said central portion and tapering towards the
same and said wings terminating midway be
tween the upper and lower edges‘ of the Wedge,
whereby to form pockets to effect additional
15
Wedging functions.

4. In a wedge, a central portion tapered in
cross section from one end to the other, wings
formed on opposite ends of said central portion,
said wings lying in spaced relation to said cen
20 tral portion, barbs formed on said wings, to aid
in holding them in predetermined position and
said wings terminating midway between the up
per and lower edges of the wedge, whereby they
disappear when the wedge is assembled.
5. In a wedge, a central portion tapered from
one end to the other, wings formed on oppo
site sides of said tapered portion, whereby to
effect additional wedging surfaces, said wings
terminating midway between the upper and lower
edges of the wedge, andv notches formed on said
Wings to aid in holding them in predetermined 10
position.
6. In a wedge, a central portion tapered in cross
section from one end to the other, Wings formed
on opposite ends of said central portion, said
wings lying in spaced relation to said central 15
portion, barbs formed on said wings, to aid in
holding them in predetermined position, and said
wings terminating midway between the upper
and lower edges of the wedge, whereby they
20
disappear when the Wedge is assembled.
