LINEMANS CHAIR.

Specification of Letters Patent.

Application filed March 19, 1910. Serial No. 550,390.

To all whom it may concern:

Be it known that '1, JOHN W. Da'v1s, a citizen of the United States, residing at San Antonio, in the county of Bexar and State. of Texas,

have invented certain new anduseful Improvements 1n L nemen's Chairs,

of which the following is a specification,

reference being bad therein to the accom- \panying drawmg.

This inventlon relates to improvements in 111181118115' chairs; and has for-its object the production of a chair which, can be "used'by a lineman when attaching cables to the supporting Y cable or line. Anotherobject of this inventlon 1s the provision of means for raising the cable by means of afoot lever so erator to easily connect-the cable ,to the 'SUE C8.

ing porting cable )orting wire without having to raise the e by hand. .Still another object tion'is the provisionof .means for facilitatthe removal of the chair from the supchair to pass along the supporting cable .without engaging any obstacles carried by "the cable itself. .Q I

With these and. other objects 1n vlew tlns I invention conslsts'. of cert'aln. novel construc- 30.

tions, combinations, 1 and arrangements of parts as-will be hereinafter fully described view of the chair supporting 44, of Fig. 3'.

which is preferably and claimed. r

Fig. 4 is a section taken on line Referring to the drawings by'num'erals, 1 desi' hates the supporting cable'below which is a apt'ed to besupported the cable 2,.which cable carries v The chair pers'e comprises a framework members 3 which are provided. at theirlower nds'with'loop-portions 4. Withinthe loopportions 4is secured a seat 5 which has each of its ends secured to the transversely extended portion 6 of the. loop po'rtions ft of .the'end frames 3. The loop-portions i -are joined asat. 7 by meansof r1vets,8, andeach frame is alsoprovided withan ovei'hanglng of the present invenand. also for facilitating the Fig; 3 is a' section taken on line '3-+3 of, Fig. 2, looking in the direction of the telephone or other wires.

safety hold theopera'tor, if it be so desired, uponportion 9 which supports asupporting roller- Patented Oct. 25, 1910.

10. The upper ends of the frames 3 are I connected by means of a channel-iron 11.

The overhanging portion 9 of the frame is spaced apart from the finger or extension- 12 so as to allow the car to be easily removed from the supporting cable 1. However,"this opening or space is normally closed by 1 means of a member 13 which is hingedly secured near the'upper end of the. finger or ex-- tension 12-as' at 14. The overhanging port10n 9. of'the frame 3 is provided with an eyelet or staple l5 and the hinged member 13 is provided with a slot 16 which is adaptedto fit over the staple or eyelet 15. Ahook 17 is carried by the hinged,member13 and when the car is placed upon the line wire" or supporting'wire 1 the hinged member is. thrown in a closed position, so that the eye 15 will pass through the aperture or slot 16 and the hook 17 is passed-through the eye 15 so as to hold the hinged-member 13 .in a closed position. The hinged member 13' is provided near its upper end with" an out-r wardl'y curvedportion 18 which facilitates the removal of the hin'gedmember 13 from the eyelet 15fwhen'it is so'desired. I The end frames carry. near the' upper end of the loop-portions '4: eyelets or hooks "19, which hooks are adapted to be engaged by books 20, carried by the supporting or strap 21. The strap 21 is adapted to the chair; I The lever member 22 is pivotally secured between the finger 12'and'one side of the supporting frame 3 as clearly shown in Figl 1 and said lever member comprlses a pm- -mary portion 23 and an auxiliary bshaped its lower end with a loop-'portion30-which may 'bflfingag d b the foot ofthe operator 'to raise the wiresupporting cable 2 to any desired position relative to the supporting cable 1. Byhaving the roller 26 so engaging thecable 2 and operated in the manner previously described, it will be obvious that the operator will be free to use'his hands to .place the necessary connecting means around.

the supporting wire 1 and the cable supporting wire 2. .Heretofore it has been necessary in many instancesfor the operator to hold the cable supporting wire in a certain position relative to the supporting Wire proper, with one hand and place'the necessary connecting means around the two wires or cables with'theother hand. j

A roller 31 is carried bythe other supporting frame 3 and is supported between the finger12 and one side of the supporting frame 3 in the same manner as the lever 22.

The wire 31 is so positioned as to allow the car to easily travel over the cables 1 and' 2, even though the cable 2 should sag and come into engagement with the roller'3l.

What I claim is 1. A device of the class described, comprising a supporting frame, a seat carried thereby, a lever member carried by said supporting frame, and means carried -by said levermember and adapted to be controlled by the foot of the operator for'supporting or raising a wire supporting cable in a desired position relative to the linemans cable below said main or supporting cable, lever means carried by said framework and adapted to engage said wire sup orting cable for raising the same to'a desired height relative to the main supporting cable, and means enga ing said lever member for allowing-"the free operation of the lever member the operator.
