"ARTICLE HOLDER"
BACKGROUND OF THE INVENTON
This invention relates to new and useful improve-
ments in article holders and although it is directed pri-
marily for use with a drill chuck key in order to hold same
upon the flexible cord of the drill, nevertheless it will
be appreciated that it can be used to hold other articles
in a similar manner.
Conventionally, a rubber lace or string is used to
hold a drill chuck key to the flexible cord in order to pre-
vent same from being lost and to ensure that it is ready
for use when required.
However sucn laces or cords often tangle with the
tool not only when hanging from the flexible cord but par-
ticularly when it is used to release the drill chuck. The
cord or lace often becomes broken and the key becomes lost or
mislaid.
_UMMARY OF THE INVENTION
The present invention overcomes these disadvan-
tages and in accordance with the invention there is pro-
vided a wire holder for detachably securing articles such
as drill cnuck keys to the flexible power cord of an elec-
tric drill or the like; comprising in combination a length
of resilient wire, a partial loop formed intermediate the
ends thereof having eacn end extending therefrom to form a
leg,preformed inwardly extending notches in the wire adja-

cent the junction of the legs with the ends of the loop
and means on the distal ends of said legs to detachably
secure same to a flexible power cord or the like.
Another aspect of the invention is to provide a
method of forming a wire holder for detachably securing
articles such as drill chuck keys to the flexible power
cord of an electric drill or the like; consisting of the
steps of forming a partial loop intermediate the ends of a
length of resilient wire with a pair of legs extending from
the ends of the partial loop, forming indented notches in
each leg adjacent the junction of said legs with said loop
and then forming partial loops on the distal ends of said
legs to engage around a flexible power cord or the like.
Still another advantage of the invention is to
provide a holder for an article such as a drill chuck key
whereby it may be held conveniently upon the flexible
power cord of the drill, a predetermined distance from the
drill so that it is readily available and easy to use in
order to loosen or tighten the drill chuck.
Another advantage of the invention is to provide
a device of the character herewithin described which is
easy and convenient to attach to the key and to the cord.
A still further advantage of the invention is to
provide a device of the character herewithin described
which is simple in construction, economical in manufacture
and otherwise well suited to the purpose for which it is

designed.
With the foregoing in view, and other advantages
as will become apparent to those skilled in the art to
which this invention relates as this specification pro-
ceeds, the invention

is herein described by reference to the accompanying drawings
forming a part hereof, which includes a description of the
preferred typical embodiment of the principles of the present
invention, in which:

ETAILED DESCRIPTION
Proceeding therefore to describe the invention in de-

chuck key 10 having a shank ll, a cross bar 12 and a chuck
engaging bevel gear 13 adjacent the inner end 14 of the shank.
This normally engages the chuck 15 of an electric
drill 16 for rotating same so that the chuck will engage or
loosen around a drill bit (not illustrated).
The invention comprises a wire holder collectively
deæignated 18 for securing the chuck key lO to the flexible
power cord 17 so that it is convenient for use.
The holder 18 is preferably formed from a single
length 19 of resilient wire or plastic which is formed with
an open loop 20 intermediate the ends thereof and a pair of
legs 22 extending from the ends 21 of the open loop 20, hav-
ing notches 23 formed at the junction between the ends 21
and the upper ends 24 of the legs 22.
Partial loops 26 are formed on the distal ends of
legs 22 as clearly shown in Figure 1.

In operation, the wire key holder as illustrated in
Figure 1, is engaged over the cross bar 12 of the key and upon
the shank 11 whereupon the two legs are crossed one over the
other to interlock the legs via the notches 23 as hereinbefore
described.
The flexible power cord 17 is then engaged within the
partial loop 26 formed on the distal ends 25 of the legs where-
upon a pair of pliers or the like is used to move these partial
loops 26 towards the closed position illustrated in Figure 4,
deforming the loops beyond the elastic limit of the material so
that they clamp in place around the cord and remain in the
clamping position illustrated.
This enables the key 10 to be readily available for
use with the chuck 15 and although it can be situated anywhere
along the length of the power cord 17, it is preferable that
it be approximately 15 inches from the drill with the legs
spread out approximately 3/4 of an inch one from the other.
Although the device is shown and described for use
with a power drill, nevertheless it can be used to secure any
article to a flexible cord or the like.
Also it will be appreciated that although it is pre-
ferably made from resilient steel wire, nevertheless under cer-
tain circumstances, it could be made from a resilient plastic
wire and the term "wire" is intended to embrace holders made
from both spring steel wire and spring plastic wire.
When the device is designed to be used with an angu-

lated chuck key as illustrated in Figure 7 and identified by
reference character 27, a split cylindrical sleeve collective-
ly designated 28 is required, to be engaged over the inner por-
tion 29 of the key just behind the bevel gear portion 13.
This type of chuck key is angulated through 90 as indicated
by reference character 30, and terminates in the distal end
portion 31 situated substantially at right angles to the inner
portion 29.
The sleeve which may be made of metal or plastic, is
cylindrical and is provided with a longitudinally extending :-~
slit 32 extending from one end to the other so that the resil-
iency of the sleeve enables it to be opened out and engaged
over the inner portion 29 of the key 27 as shown in Figure 7.
holder
The key / is then engaged around the sleeve by means
of the loop 20 as hereinbefore described and it is prevented
from disengaging from the sleeve by the provision of a pair of
spaced annular outwardly extending beads 33 formed around the
body of the sleeve spaced inwardly from the ends thereof as
clearly shown in Figure 6.
The key holder is then secured to the cord 17 by the
loops 25 as hereinbefore described.
Since various modifications can be made in my inven-
tion as hereinbefore described, and many apparently widely dif-
ferent embodiments of same made within the spirit and scope of
the claims without departing from such spirit and scope, it is
intended that all matter contained in the accompanying specifi-
