CABLE CHAIR.

lpplicationfiled October 21, 1921. Serial No. 509,450.

To all whom it may concern/k Be it known that I, CALVIN E. STnoU'r, a citizen'of the United. States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Cable Chairs,-.;

. of which the following is a specification.

' My invention relates to a trolley supported chair for telephone or 'other...1ine men where wlres are to be strung on a pair of cables one above the other.

This rollingchair is designed to be sus I pended by both the upper and lower cables and to run freely over the rings or hooks through which the telephone wire cables are drawn. p

Under the old system of-stringing telephone wires the ,line men made use'of a trolley supported chair which was adapted to run on a single cable only so that it was not adapted to cases where the supporting cables were two in number oneabove the other. with telephone wire cables bring to each,

Accordlng to my invention, I make use of a seat member which 1s substantially a flat board or plank with a frame at each end for supporting the seat member on the two supporting cables.

Each frame has journalled to it a ld'wer grooved pulley resting on a lower supporting cable and an upper grooved pulley resting on the upper cable.

In practice, 1 construct these frames with an opening on one side to admit the upper cable so that the chair maybe put in p'oof aplank or board-having its lateral edges chamfered so that, a' man can sit on the board with his legs overhanging. Ateac-h end of the seat member 1 is a supporting framepreferably formed of, metal strips bolted to the seat member.

As here shown, the frame consists of an upright strip -3 bolted near the endofthe f subjected to an equal tension or not.

invention by means seat with a reinforcing strip at forming "an offset at the lower end and also bolted to the-seat and forming an open space with the strip 3-for the lower truck 5 running on the lower cable 6. The truck 5 is journalled between the strips 3 and 1 by a suitable pin or axle.

A. suitable slot is formed in the seat to allow thetruck 5 to project through and to bring the seat some distance above the lower cable. The strip 3 extends upward to a point somewhat above the upper cable where it turns downward upon itself enclosing the upper truck 7 which is journalled to the two sides of the strap. The extreme end of the strap torms'aterminal 8 bent to leave an open space by which the device can be hooked over the upper cable .9. The central portion of the strip 3 is bent outward to form a lateral stifiening projection 10. The structure is stifi'ened by a brace 11 secured to the seat near the lower truck 5,.

the brace extending upwardto the top of the frame being riveted at the top and also to the projection 10 at an intermediate point.

This construction of the frame makes a vertically rigid structure with an open side adapting it to be hookedover the upper; cable and sufficiently rigid to hold the seat. The device is pushed along the cable,

the trucks overrunning the'hooks or rings 12 through which the telephone wire cables are threaded.

Itis immaterial whether both cables are one of the cables is slack the tighter one will be suflicient to hold the chair in place.

'I claim: A trolley chair for telephone or other line men consisting of a fiat elongated seat, a suspending frame secured to each end of said The chair may if desired be used on a seat, saidv frame being composed of an upright strap secured to the seat, the lower end having an offset forenclosing and journal; l ng, the lower truck. the upper end of the.

frame being bent over to enclose and form a journal recess for the upper truck, the

central portion being swelled or bent out- ,j ward to form a stiffening projection and,

the strip terminating in a lateral book. a
