GEORGE REPLOGLE, OF LA FAYETTE, INDIANA.

LINEMANS CHAIR.

mac ete.

To all whom it may concern:

Be it known that I, GEORGE REPLOGLE, a citizen of the United States, residing at La Fayette in the county of Tippecanoe and State 01 Indiana, have inventedcertaln new and a useful Improvements in Linemens Chairs, of which the following is a specifi cation;

This invention relates to cable inspecting devices attached to, and moving with, a linemans chair or equivalent device, such as is ordinarily supported by, and runs upon, a

supplemental supporting cable or wire,

sometimes known-as a messenger cable, the latterbeing arranged in proximity to a cable or conductor of a telegraph or telephone line or any other employer of electricity and supporting the same, in order that the occupant of the chair may conveniently inspect the said conductor and repair it if necessary.

Such a line nans chair, as heretofore c011- structed, and without my novel appliance herein described, will permit the occupant of the chair to inspect the cable or other conductor from above with convenience, but he must bend inconveniently and more or less twist his body to obtain a view of the underside of the cable, so there is always some risk that defects not easily discernible from above may altogether escape notice; besides, the work is impeded and delayed and the inspecting lineman is made needlessly uncomfortable. If the chair were hung so low as to afiord a good view of the underside of the conductor in a natural position of the lineman there would be even greater difliculty in obtaining a clear view of the upper part of the conductor. In short, it is not possible to hang the chair and its occupant so that all parts of the conductor or cable will be seen by him distinctlyand at once from one point by direct view.

To do away with this disadvantage l employ also indirect or reflected vision, providing the chair with a mirror which will supply a reflected image 01": the parts of the cable or conductor not seen from above, while the direct vision of the lineman suffices for the upper parts. of said conductor; consequently the lineman while retaining a single natural posture with his eyes at one point can see at a glance all of the wire, both above and below the center, which Is for the time in proximityto the chair or Seat and the mirror. By moving the chair Specification of Letters Patent.

A designates the chair suspending or messenger wire, B the conductor or cable which is supported by said messenger and which is to be inspected, C the bent suspending arms of the linemans chair, D the platform which constitutes the seat of the said chair, E a stout base bar, which extends longitudinally under and in contact with said platform or seat, and is supported adjustably by the lower ends of said arms, being also clamped to said. seat by a pair of metal clips or brackets F, which are bent to receive and fit the ends of said bar and are secured to said seat or platformby bolts G. The upper parts of the arms G are bent to supply recesses receiving. the grooved rollers H, which rest on the supporting messenger wire A and suspend the chair movably as usual, said rollers running along the supporting cable or messenger wire A as the chair is pulled from point to point by the lineman. These rollers turn on ordinary spindles g, which may be in the form of bolt as shown, passing through the parallel upright bars of the bent upper parts of said arms.

From the bent upper part of each arm 0 an outwardly and downwardly curved mir- Patented May "8, 191%.

' 3v a segmental rack adapted to mesh with the ridges j of the corresponding pair of bifurcations J in any one of'diverspositions of the tilting of the mirror 2 and said bar 3.. A pivot bolt L passes through each pair of such bifurcations J and has an eye-bolt M hung thereon between each pair ofbifurcations J The lower end of'said eye-bolt passes throughthe extension K of bar 3 proximate thereto and receives below the latter a. nut N. The two nuts N are the clamping devices for holding the mirror 2 in any position of inclination to which it may be tilted around said disk-form bifurcations J. To adjust the inclination of the mirror 2, these nuts N are loosened, the mirror is shiftedon its longitudinal axis to the position of inclination desired and the nuts N are tightened again, drawing the ridges 70 of. the segments K into engagement with different ridges from those previously engaged. By tightening said nuts the mirror is held securely in its adjusted position.

The mirror is of suflicient length to permit a considerable extent of the conductor to be inspected both below as well as above without shifting the position of the chair, and reaches, as explained, nearly from one of the end arms 0 to the other. The end arms C, the base bar E and brackets F with their bolts make up a strong frame for the chair and the arms C serve an additional purpose as mirror supports by reason of the downwardly extending parts I and the j ournaling construction above described.

Having thus described my invention, what Iclaim as new and desire to secure by Letters Patent is:

l. A suspending device for a cable inspector, adapted to be moved along in a line parallel and proximate to a cable or other conductor of electricity and provided with a mirror arranged to show theunderside of the conductor to a person inspecting the upper. side thereof.

2. In combination with [a supporting means arranged parallel and proximate to a. conductor and a device supported by and running along the said fmea'ns and adapted to carry a person, a mirror attached to said device andarranged to show the lower part of the conductor to one in said device who inspectsthe conductor from above.

3. In combination with a linemans chair and a supporting wire or cable from which said chair is movably suspended in proximity to a conductor, a mirror carried by said chair and arranged to show the lower part of said conductor to an occupant of said chair while the upper part of said conductor is inspected by him from above.

4. In combination with a chair-supporting cable, a linemans chair suspended therefrom by arms provided with rollers which run on said cable and a mirror carried by said arms and arranged to display the lower part of the conductor to be inspected.

5. A pivoted mirror arranged in proximityto a cable which is to be inspected, in combination with a linemans chair and a supporting cable from which said chair is suspended and on which it is movable endwise of said cable, the said chair bein provided with arms from which the sai mirror is suspended for tilting, and with means for locking said mirror in any position to which it may be thus tilted.

6. A tiltable mirror for a linemans chair, said mirror having attached longitudinally projecting parts serrated on their upper faces, in combination with suspending means having correspondingly serrated parts and means for clamping together said projecting parts and suspending parts, with their respective serrations inengagement, in any one of divers positions into which said mirror may be tilted.

7. A suspending frame for a linemans chair, provided with disk-form ridged art's and pivots, in combination with eyeolts hung from said pivots and a mirror having attached terminal parts which are perforated to receive said eye-bolts and provided with ridges on their upper faces for engagement with the rid es of said diskform parts, in any one o divers positions of inclination of said mirror and said terminal parts.

8. A tiltable mirror, in combination with a linemans chair and its suspending frame having downwardly presented disk-form bifurcations peripherally ridged, a bar attached to said mirror and having on its ends segmentally arranged ridges for engaging the ridges of said disk-form parts, pivot bolts extending through each pair of bifurcations and means for suspending said bar and mirror from said bolts, said means being adapted to be tightened for clamping said ridges into engagement into any positi'on of tilting assumed by said mirror.

9. A suspending device for, a cable inspectoradapted to be moved along in proximity to a cable or conductor and provided with a tiltable mirror and means for locking said mirror in any one of several positions of inclination, said mirror serving to show the underside of the cable. j

10. A suspending device for a cable in- 30 spector provided with serrated parts, in imity to a cable or conductor and provided combination With a mirror having serrated with an adjustable reflector and means for parts attached thereto and adapted to enlocking said reflector in any one of several gage the serrated parts first mentioned in any positions of adjustment, said reflector serv- 5 one of several diiierent positions of inclina- .ing to show a portion of the cable or con- 15 tion of said mirror and means whereby said ductor.
