LINENIANS CHAIR.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application tiled September 14.1906. Serial No. 334.693.

l what mav be termed hnemens chairs. Its l j object is to promote 'facility and convenience in the linemens duties in traveiing from pole to pole in Stringing additional wires and otherwise equipping telephone-lines and the like, also to insure safety against accident or falling Vfrom his mid-air position, and to accomplish these ends in a simple, expeditious, and e'fl' otive manner.

Said invention consists of certain features or instrumentalities, substantially s hereinw after fully disclosed and specifically pointed out by the claims.

In the accompanying drawings, illust ating the preferred embodiment of our invention, Figure 1 is a perspestive view thereof in position for use. Fig. 2 is an end elevation of the contrivance. Fig. 3 is a plan view of the same, and Fig. hfl is a vertical seo tion produced through the forwnrd hanger, pulley, and other parts.

In carrying out our invention we provide a seat 1, preferably in the form of 'a board, es shown, having continuous arms and back 2, preferably of stout strong rod formation, whioh all constitute the linemens choir proper. Said seat or board has depending in fixed position Vfrom its forward under side a rigid or iron foot-rest 3, preferably of practically inverted-T form, and is itself suspended by rigid hangers or Suspenders 1l 5, these in turn having upper-end returned por tions 6 7, between which are arranged pulleys 8 9, whose journals rest or ere received in openings in the same, shown. These pulleys travel upon a cable or wire, as seen, and may be suitably equipped upon their peripheries with rubber tires to guard against their possible slipping upon said cable, as might otherwise happen, especially in frosty weather.

Said hangers are firmly connected o together by a suitable brace or rod 10 spanning the distance therebetween and fixed in any suitable way to said hangers upon their upper surfaces.

The pulleys S 9 have their journals pro- 55 vided with toothed or sprocket pinions 11 12 13, two, 11 12, being lixed to the journal of one pulley, and encompassing one of which and the single pinion 13 of the rear-end pulley 9 is an endless chain or belt 14 for thev sio multaneous propulsion of the two pulleys. The pinion 11 of the forward pulley 8 and a like pinion 15 are engaged by a second endless chain or belt 16, the shaft 17 of the latter pinion being suitably journaled in one of said hangers and having fixed thereto crank-arms 1S, adapted to be manually actuated by the lineman, who may be seated in the chair aforesaid. By this arrangement it is obvious that the lineman may propel himself 7o along the line from pole to pole in attending to the equipment of the poles with additional wires with Vfaciiity and assurance of comparative safety in his mid-air work,

It will be noticed that the hangers 4 5 are 75 delleeted or bent, as at 19, to eseape contact with the cable or wire subsequently placed or suspended in position, as indicated.

l/Ve claim- 1. A device of the character described, em- 8o ploying a chair 'fixed to rigid Suspenders o1' hangers rigidly held together and equipped with wheels or pulleys at their upper ends, said pulleys having their journals or shafts provided with pinions, means fer conjointly 8 5 propelling said pinions, an additional pinion supported upon one of said hangers, means for transmitting motion from the latter pinion to one of the aforesaid pinions, and means for manually propelling said latter' 9o pinion,

2. A device of the character described, employing a chair -fixed to rigid Suspenders or hangers rigidly hold together and equipped with wheels or pulleys at their upper ends, said pulleys having their journals or shafts provided with pinions encompassed by an endless chain or belt and a pinion supported or journaled upon one of said hangers and names to this specification in the presence of encompassed by an endless chain or belt also two subscribing Witnesses.

engaging one of the aforesaid pinions, said GEORGE P. YEAKEL. hanger-supported pinion having its journal WHORTON C. L. IRELAND. also equipped With manually-actuated erank- Witnesses: arms. l J. C. SNYDER,

In testimony whereof We have signed our l CLAY U. KELLAR.
