WITNESSES W. D. KYLE SECONDARY RACK Filad Sept. 24, 1925 .INVEN TOR Patented Apr. 7, 1931 UNITED STATES PATENT OFFICE WILLIAM I). KYLE, 0F MILWAUKEE, WISCONSIN, ASSIGNOB, BY MESNE ASSIGNMENTS,

T0 LINE MATERIAL COMPANY OF SOUTH MILWAUKEE, WISCONSIN, A CORPORA- 'IION OF DELAWARE SECONDARY RACK Application filed September 24, 1923. Serial No. 664,474.

The invention relates to secondary racks.

The object of the invention is to provide a secondary rack, more particularly for use on line poles and other suitable supports, in which the usual malleable or steel brackets for carrying the insulator supporting rod are dispensed with and arms having direct connection with the insulator supporting rod are bolted directly through and to the pole or support, thereby reducing the number of parts, the amount of material and the cost of manufacture to a minimum.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the accompanying drawings, Fig. 1 is a side elevation of a secondary rack embodying the invention, parts being broken away and parts being shown in section, and

Fig. 2 is a transverse sectional View taken on the line 22 of Fig. 1.

In general, the device comprises supporting arms 20 each having a bolt end portion, and a supporting rod or member 25- detachably connected to said arms and having insulators mounted thereon.

The bolt end portions of the supporting arms 20 are adapted to extend through a pole 9 or other support, and their ends are threaded to receive nuts -21 by which the arms are clamped to the pole, an annular flange 22 being formed on an intermediate portion of each arm for engagement with one side of the pole. The insulator-supporting member 25 is preferably a channel bar with its web provided with openings to receive the threaded end portions 26 of the projecting arm 20, the channel bar being clamped to these bars by nuts 27.

Spool insulators 29 are mounted on the member 25 against relative rotation, these insulators having polygonal holes therein through which said member passes and being secured thereon against longitudinal dis placement in any suitable manner, as by means of cotter pins 30 inserted in openings in the webs of the channel, washers 31 being preferably provided between the ends of each insulator and said pins 30. With this about one of the supporting arms on which it may be frictionally held by temporarily tightening one of the nuts, thus permitting the use of both hands while mounting new insulators.

It will be noted that the arms have bolt end portions and that the heads of these portions are arranged intermediate the ends of said arms to space the insulator-supporting member at the desired distance from the support.

I desire it to be understood that this invention is not to be limited to any specific form or arrangement of parts except in so far as such limitations are specified in the claims.

IVhat I claim as my invention is 1. In a secondary rack, the combination of a pair of spaced parallel bolts to fixedly enter a support and project therefrom and each having an intermediate shouldered portion engageable with said support, and a straight channel rod secured to the projecting end portions of said bolts to extend between said bolts in spaced relation to said support and having spaced spool insulators threaded thereon.

2. In a secondary rack, the combination of a pair of spaced parallel bolts to fixedly enter a support and project therefrom, a channel rod having the opposite end portions of its web secured to the projecting portions of said bolts to dispose said rod between said bolts in spaced relation to said support, and spool insulators threaded on said channel rod and fitting thereon against relative rotation.

In testimony whereof I affix my signature.

WILLIAM D. KYLE.
