2 Claims. (Cl. 248- 221) This invention relates to splicing devices or attachments for poles and particularly a bracket clamped over the upper end of a pole having upardly extended arms for attaching a cross bar to the upper end of the pole with the bar spaced above the end of the pole.

The purpose of this invention is to provide means for temporarily suspending a cross arm across and above the upper end of a pole while repairs are being made to connections on the pole or while permanent cross arms are being mounted upon the pole.

In making installations of hot or high tension wires on telegraph and other wire supporting poles it is desirable to support the wires above the upper end of the pole to facilitate working on the pole without danger of contacting the wires. With this thought in mind this invention contemplates an extension member in the form of a saddle clamped to the upper end of the pole and having upwardly extended arms to which the temporary cross arm is attached whereby the device mounted on the upper end of a pole conductors for high tension wires may be suspended therefrom.

The object of this invention is, therefore, to provide means for forming a saddle or extension element, whereby a cross arm may be temporarily suspended above the upper end of a pole.

Another object of the invention is to provide an extension element for poles whereby cross arms are temporarily suspended above the upper ends of poles that may be mounted on poles and attached to the cross arms without changing the poles or cross arms.

A further object of the invention is to provide a temporary cross arm support adapted to be clamped on the upper end of a pole which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a pair of substantially U-shape clamps having adjusting bolts extended through flanges at the ends with a. strap extended upwardly from the clamps for forming a saddle on the upper end of a pole and cross arm supporting arms extended upwardly from the clamps.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view showing the extension mounted on the upper end of a pole with a cross arm in the upper end thereof.

Figure 2 is an end elevational view of the extension.

iii

Figure 3 is a sectional plan taken on line 3-3 of Figure 2 showing the clamps and straps.

Figure 4 is a cross section through the extension taken on line 4-4 of Figure 2.

Referring now to the drawings wherein like reference characters denote corresponding parts the pole extension device of this invention includes a pair of clamps I and II channel shaped in cross section, a strap I2 and upwardly extended arms l3 and I4.

The clamp I0 is provided with flanges I 5 and I6 and the clamp II, with coacting flanges l1 and I8 and bolts I9 and with spacing sleeves 2| and 22 thereon respectively extend through the flanges, as shown in Figure 3. The bolts are provided with nuts 23 and 24 and washers 25 and 26, respectively may be used under the nuts.

The strap I2 is positioned around the sleeves 2| and 22 on the bolts of the clamp members, and the strap, which extends upwardly over the upper end of the post, as shown in Figure 1, is provided with a buckle 21 for adjusting the position of the extension member.

The upwardly extended arms [3 and I 4 are provided with triangular shaped openings 28 and 29, respectively and

bolts

30 and 3| with

spacing sleeves

32 and 33 thereon, respectively are positioned in the upper ends of the arms, thereby providing supporting elements for a cross arm as indicated by the numeral 34. The

bolts

30 and 3| are provided with nuts 35 and openings 36 are provided through the upper ends of the arms through which the arms may be attached to the cross arm 34 by bolts 31.

With the parts arranged in this manner the extension elements or saddles are positioned over the upper ends of posts as indicated by the numeral 38 and with the strap l2 providing a saddle on the upper end of the post the bolts l9 and 20 clamp the end of the clamp members together, through the nuts 23 and 24 whereby the extension is rigidly clamped on the upper end of the post. With the extension in position the cross arm 34 is secured in the upper end between the arms l3 and I4, thereof by the bolts or screws 31.

High tension or, hot wires may be suspended above the upper end of the post without danger of workmen repairing wires, or mounting cross arms on the post coming in contact with the hot wires.

It will be understood that modifications may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. A cross arm supporting bracket comprising substantially U-shape clamps having flanged ends, bolts with spacing sleeves thereon extended through the flanges at the ends of the clamps, a strap extended from the sleeves on the bolts upwardly over the end of a pole positioned between the clamps, substantially triangular shaped arms with outwardly diverging sides extended upwardly from the clamps and secured to the clamp at the apex of each arm, and bolts extended through the arms providing rests for a cross arm positioned between the arms.

2. In a cross arm supporting bracket, the combination which comprises substantially U-shape clamps channel shaped in cross section and having flanged ends, bolts having nuts on the ends thereof extended through the flanges at the ends of the clamps, spacing sleeves positioned on the bolts, an upwardly extended strap positioned around the sleeves on the bolts, upwardly extended side arms having elongated upper ends carried by the clamps, spaced bolts extended through the upper ends of the arms, and spacing sleeves positioned on the said spaced bolts.
