JAMES F. WILSON, OF WICHITA FALLS, TEXAS.
SUPPORT FOR TELEGRAPH LINE-WIRES AND THE LIKE.1,266,736.
Specification of Letters Patent.
Patented May 21,1918.
Application Sled July 31, 1917. Serial No. 183,872.
To all whom it may concern:
Be it known that I, JAMES F. Wumsox, a
citizen' of the United States of America, re-
siding at Wichita Falls, in the county of
s Wichita and State of Texas, have invented
certain new and useful Improvements in
Supports for Telegraph Line-Wires and the
Like, of which the following is a specifica-
tion.
to My invention relates to supports for tele-
graph and telephone line wires, electric light
line wires, and the like, and the object is to
provide simple and highly efficient brackets
for holding such wires securely in place and
i5 devices which are easily and quickly in-
stalled and devices which will hold the wires
securely from post to post so that the wires
will not drop to the ground except possibly
between the posts where the break occurs in
i a wire and to hold the wires in case of ex-
pansion of the wires so that the only drop-
ping of the wires will be the sag between
two posts. Other objects and advantages
will be to provide devices that will/ endure
, indefinitely as there will be nothing to decay.
The devices will be fully explained in the fol-
lowing description and the invention will be
more particularly pointed out in the claims.
Reference is had to the accompanying
drawings which form a part of this appli-
cation.
Figure 1 is a side elevation of the support-
ing apparatus, showing an ordinary post
broken away. Fig. 2 is an enlarged detail'
as view of a clamp. Fig. 3 is a detail view of a
clamp lock. Fig. 4 is a detail view of the
insulation. Fig. 5 is a vertical section, taken
substantially on the line 1-1 of Fig. 1. . Fig.
6 is a plan view of the main bracket bar.
40 Similar characters of reference are used
to indicate the same parts throughout the'
several views.
A post 1 of ordinary type is shown broken
away at the bottom. The cross bar 3 has an
45 off-set to receive the post 1 and the bracket
will be gained into the post in the usual man-
ner so that the weight .will be directly on
the post. The cross bar or main bracket bar
8 'is preferably made of metal. Braces 4 are
so attached to the post 1 and to the bar 8 for
making the bar 3 rigid. The wires 5 are
clamped securely against longitudinal move-
ment. Insulation blocks 6 are provided and
each insulation block6 consists of two parts,
a the planes forming the meeting faces of the
two parts being vertically arranged so thatthe two parts can be clamped on the wire 5.
The two parts of the block 6 are clamped on
the wire by a spring clamp 7. The bar 3 has
vertical openings 8 to receive the clamps 7. 60
After the insulation has been placed on a
wire, it is placed in the clamp 7. The arms
of the clamp will be sprung together and
inserted in the vertical opening in the cross
bar 3 and driven down to the positions illus- 65
trated. The insulation block 6 will be se-
curely clamped on the wire so that the wire
cannot move in the insulation or through the
insulation 6. The insulation block 6 may
be provided with flanges 9 at each end to 70
prevent the insulation blocks from moving
Iongitudinally in the clamps 7. The clamps
7 .are locked securely in the cross-bar 3 by
wedge shaped keys 10 driven through hori-
zontal recesses in the bar 3, the horizontal 75
openings intersecting partly the vertical re-
cesses. One arm of the clamp 7 has a cut-out
11 to receive the key 10 so that the clamp
will be securely locked against vertical move-
ment in the bracket bar. The key 10 may be 80
serrated or notched on one edge, as at 12, to
form slight shoulders on the key to prevent.
backward movement of the key through the
bar 3. The shoulders will catch against the
angle formed by the recess and the face of 86
the bar and thus prevent backward move-
ment of the key after it is once driven
through the bar 3.
There may be as many bars 3 on a post as
may be necessary and there may be as many 90
clamps in each bar as may be necessary or ex-
pedient. Various changes in the sizes, pro-
portions, and construction of the various
parts may be made without departing from -
my invention. 95
What I claim, is,-
1. A support for telegraph line wires and
the like comprising a cross-bar having verti-
cal openings and horizontal openings inter-
cepting said openings, clamps secured in 100
said openings, flanged insulation in two
parts carried by said clamps and clamped on
the line wires by said clamps, and means in
said horizontal openings for locking said
clamps against vertical movement. 105
2. A support for telegraph line wires and
the like comprising a cross-bar having ver-
tical openings therethrough, line engag-
ing members, each consisting of a block of
insulation in two' parts for receiving a wire 11
and having faces meeting in a vertical plane,
a clamp bent about the parts of said insula-
