1 Claim. (Cl. 24-?73)
My invention aims to provide any improved
clip for use in holding one or more wires, con
duits, pipes and like members in position on a
In the drawing which illustrates preferred em
bodiments of my invention:
Figure 1 is a plan view of a portion of an
installation including one of my improved clip
Fig. 2 is a section taken on the line 2-?2 of
Fig. 3 is a section taken on the line 3?3 of
Figure 1;
Fig. 4 is an edge view of the installation shown
15 in Figure 1 from the right-hand side thereof;
Fig. 5 is a bottom plan view of the installa
tion shown in Figure 1;
Fig. 6 is a section taken on the line 6-?6 of
Fig. 3;
Fig. '7 is a perspective view of the clip per se;
Fig. 8 is a side elevation of a second form of
improved clip.
At the outset I wish to have it understood that
25 I am aware of the fact that clips appearing to be
like mine are old. However, I have made certain
improvements which may appear slight but
which in practice have proved to increase the
commercial use and value of such clips.
My improved clip shown in Figs. 1 through 'I
is preferably formed from a spring material such
as brass or high carbon steel and has a generally
U-shaped body provided with legs I and 2. The
leg I has an outwardly bowed portion 3 to ?t
35 over and hold in place a wire, pipe or the like
as shown in Fig. 3. The leg 2 has its free end
bent outwardly to provide a guide portion 4.
in shape and are formed by simply shearing or
slitting the metal and then bending up the sharp
pointed portions, as shown in Figs. 3 and 7.
My improved clip is shown in connection with
holding a wire 6 (Fig. 1) to a relatively thin sup-v
port ?I by slipping the bowed portion 3 over the
wire and then pushing the clip over the edge
of the support as shown in Fig. 3. The guide
portion 4 helps to guide the clip over the sup
port by providing a cam surface and the ends l0
of the prongs 5?5 ?dig? into the support to
prevent the clip from jarring loose from the sup
port as friction alone will not work satisfactorily
when a clip is used on a moving support.
My other form of clip, shown in Fig. 8, is the 15
same as that shown in Figs. 1 through 7, except
that the legs I and 2 converge toward their free
ends, thus increasing the grip of the prongs
against the support.
My improved clips are simple in construction,
ef?cient in operation, easy to apply and they are
being sold in large quantities having taken the
place of other clips which do not have my im
proved vguide means, gripping formation and .
While I have illustrated and described pre
ferred embodiments of my invention 1 do not
wish to be limited thereby, because the scope of .
my invention is best de?ned by the following
I claim:
A clip of the class described comprising a strip
of metal bent into a generally U-shaped body,
wire, tube, rod and the like positioning means
provided as a part of said clip, the end of one '
leg of. said U-shaped body portion being bent
away from the other leg to provide a guide means
assisting in engaging said clip with a rigid sup
Adjacent to the point where the guide portion 4
joins the leg 2, I have provided a pair of prongs port and sharp pointed prongs cut from the ma
terial of said leg with the bent away end and
40 5?5 which are preferably formed from the mate-.
rial of the device. These prongs 5-5 may be lo - said prongs being located inwardly from the end
cated at any suitable place where they will engage of the bent portion and having their free ends
a support, but I have found that they can best about in a plane with that portion of the-inner
be located adjacent to the\opposite edges of the
45 leg?2, as shown in Figs. 2 and 6. Furthermore,
I have found that the best prongs are triangular
surface of said leg where the curved portion joins
the leg. '
