LINEMANS CHAIR Application led December 12, 1927.

relates to improvements in and has for its primary object a linemans chair, the wheels of which are provided with a resilient center portion or easily negotiate or ride over cable hangers, clamps and thinibles because the tread being resilient can compress when riding over these obstructions and consequently the lineman in the chair is not jarred as is the case'where wooden or metal wheels are used.

A further obj eet is to construct a linemans chair, the yoke of which is so arranged that in the event ot the chair being tilted and the wheels sliding od of the wire, the yoke wi hook on to the wire and prevent the chair from falling to the ground. By this construction, the possibility of injuring persons passing along underneath the Wire is eliminated.

In the drawings:

Fig. 1 is a side elevation of my device;

Fig. 2 is an end view of the saine;

Fig. 3 is an enlarged vertical cross section of one of the wheels showing the manner of assembling the same; and

Fig. 4 is a Jiragmental cross section of a wheel showing a different type of tread.

In the construction of my device I einploy a yoke 5, which is provided with downwardly and outwardly diverging arms 6 and 7. The arm 7 terminates in a hook 8, which projects upwardly and inwardly. The arm 7 is also provided with a downwardly extending guide or guard 9.

Carried by the arm 6 is a stirrup or bracket 10 to which the seat board 11 is secured. In order to couple two yokes together, I employl a cross rod or bar 12, which has its ends 13 secured to the yokes. The yokes are urther secured to the bar 12 by means of brackets 14, one of these brackets being on each side of each wheel. This prevents any possibility of the yokes moving backward and forward on the bar 12.

The wheel is composed of side members 15 and 16. These side members have their inner face grooved or channeled out as indicated by the numeral 17 so as to form a shoulder 18.

Formed integral with the members 15 and 16 and projecting from the inner faces there- My invention linemans chairs,
