T @ZZ whom it may concern:

Be it known that l, Holman P. CHANDLER, a citizen of the United States of America, residing at Mansiield, in the county of Richland and State of Ohio, have invented cer-` support for gripping a trolley wire and suspending it from an overhead hanger.

One object of my invention is to produce a device having incorporated therein means for securing the device to a hanger or other support, and havingv means which can be rotated into -alinement with the conductor and caused to grip the conductor and in which the parts of which the device `is composed are held together against disassembly after being brought into proper assembled relation. i

My invention resides in the new and novel construction, combination and arrangement 'of the various parts herein more fully set forth and described in this specific-ation and shown in the accompanying drawings. Further objects of my` inventionl will be hereinafter disclosed in connectionwith the detailed description of my preferred form of construction.y 1

In the accompanying drawing:

Fig. l is an end view` in elevation of` a construction embodying my invention and showing' the same in engagement with the `trolley wire.

Fig. 2 is a side view in elevati'onofF'ig. l.

Fig. 3 is a transverse section of Fig. 2 on the line 3 3. p

Fig. 4 is a sectional view'of Fig. 3 on the line 1- 4. y

Fig. 5 is a transverse sectionalview corresponding to the view shown inlig. 3,\eX cepting that the jaws are shown opened up in condition to receive a trolley conductor.

In the preferred form of' construction embodying my invention l employ "a supporti ing member l having a threaded'recess 2 to receive a threaded stud of an overhead support to which the, device is secured. The member l is providedwithl allange 3 which f screws against the face ofthe hanger `or support. Intermediate the ends or the member l isa threaded portion 4 and projecting below the threaded portion 4` is ya neck 5,

to the lower end or' which is aprojectinlg f' flange 6 all forming an annular groove about the neckl between the members 4L and 6.` Projectingdownwardly on diametrically opposite sides of the member'l are ylugs 7 7 each `forming a channel with 'f the adjacentface of the neck portion 5.

Loosely mountedupon the support member l and ldirectly upon "the ange 6 are two clamping members 8&8 independently movlable with respectto each other and ywith f respect to the supporting member lf and also rotatable upon the support memberv l about its vertical axis, but limited Aasy to the extent of rotation. Each jaw member is provided withv a sliding ulcrumedg'e 9&4

which engageswith the flange'l 6 and each A clamping member is also provided with an upstanding collar 10 whichlits in the channel formed bythe parts 5 and 7. rlhe eX- treme lends of the collar l0 are provided f with projections l1 which engage withthe lug 7 and limititherotation of the mem` bers y8` relative yto the member l. Each member 8 is provided with a lip 12 adapted to engage with vthe trolley conductor 13 and -`each member 8 is alsolpro'vided witha flange 14 and 'shown as provided with a beveled face l5.` y r i It will be observed Vfrom a `study ofFigs.

3 and 5 that the engagement of the edge 9 l with the upper surface or" the member:6 forms a sliding :fulcrum while the construcytion formed by the positioning of the collar lOin the` channel formed by the lug Tand `member 5 produces a true fulcrum about which the members 84-8piv`ot with respect to the lsupport member l. i l II have found thaty sincethelugs I+-.7 'engage and hold the clamping members 8 8 from' moving outward at the upper end that I am able to eliminate-a twisting or` canti'ing effect upon the members 8-8 when the `member `16 is broughtinto ,arotatable engagement therewith and `hence permitting a more positive `action of the `members 8-8 vin gripping the conductor. Thesame is true when the member 16 is rotated `in the `reverse direction to release kthe conductor .'l'fromfthe gripof the members 8-'-8.

` `Mounted on the threaded portion 4 of the 'member yl is an operating member 16 provided withl athreaded yrecess engaging with the threads on the portion of the member l so that when the member 16 is rotated it with the beveled face 15 of the .members 8--8. The -0pposite edge Vof the member `16 is provided with p originally formed straight, as shown by the-.dotted lines, and which after assembly oftthe parts is rolled or bent inwardly so asztoiengagetherlange B and thereby limit the: movement in one 1 direction. of' the member firelative to the members 1 and8.-

Thekmember `16 is firstk positioned yupon the member 1 withontturning inthe vflange L19and `themember 1G is positioned near ,the upper'. end of the member 1 so'that ,thegsurfaceiQO ,willengage .with-the lange. The members land 8 are then vassembledby 1in- .terlocking the fla-nge y10 within the channel formed-.between the .parts 5 Vand `7 .as indicated in Fig. 5, but zthere '.willibe no `interference ofthe-members 8 .with the member K'16:becausetthesurface 2O will .be ini. engage ment ,withthe flange 3. The-.relation of the

parts

6, 7,5and l1l) are snchas to permit theinterlockingfoffthe vparts as described. After the apartsil .and 8--8 have been iin- `terloclred fthe member 16 isbrought ydown f into engagement withtheimemliiers 8 8aiid the vflange j 19 turned l.or :rolled inward: s o as lto engage with-the flange 3 thereby limiting the movement .of the operating niemberl away froin "the clampingzmembers. 8-8 and preventing theilange 17 -from movingfaway from the flange 14 a .dist-ancewhich' permit the members 8-8 ,to :become fdiseng-aged lfrom fthe `member .1, that*i-s, :the

engagement :between z the members 8-g8 Yand ythe member 16 is maintained at Vsuchra point that the :members -8-8 Vcannot be diseenl.gagedvfrom .the `member l1' after the flange 19 :has been Jformed lor rolled V.iinvvariil ,so as :to engage fthe flange 3.

y .In order to install` the `device ljust described it is only necessary-:torotate the device into engagement-'with .the -stud o an Aoverhead support Aor hanger iwhich may fbe done by grasping the jaws and rotatingfthem 'inthe .proper 4direction which in :turn will *cause the member "1 Ato'be rotated as the lugs 11 will Vengage with theilugs or yrotation -maybe brought about by rotating the membei' 16 iin-'the iproperwdirection ,which will f cause :rt-he .member t1 i to; rotate on account .of the :engagement of the -ilange .19 iwith :the `flange 3. Attergthe deviceihasibeen secured to the hangerstud'it maybe ,toundithatithe "clampingmembers8-8 ,are not in alinement with the :trolley conductor., but the proper .alinement can be brought about by rotating y'the members. A8'--.8..iii the i opposite direction "fromwthatemployed in rotating the 2 member 1, until the jaws are in proper alinement a .liange .19 which was will yporting Y member i to engage :move them `into engagement with lthecon- Vbackward direction or loosen it from the hanger stud to whichjit has been secured on account of the amount of independent rota-l tionpermitted tliejaws due to the spacing of the lugs 11 on the members 8 8 with respect to the lugs 7 on the member 1.

Having brought the clamping members into alinement with thek trolley conductor the jaws'ai'e spread apart as `shown in Fig. 5. and .the trolley conductor insertedbetween the Alips 12--12 and the clamping members .i5-f8 are then moved into engagement with the trolley conductor byrotating the memb er loin theproper direction to move .the lips toward each other. This operation can as a rule be carried out by the-hand of the operator,` but after'thelipsare in engagement with the conductor then it is customary to apply ar wrench to the .faces 21 of the member 16 wherebythe member 16 willffoice .the membersv intostrong andsecure engagement with thetrolley conductor..

i It will.be. evident.tojthose skilledin `the art that variations may be produced from thatjust ydescribed without'J departing from mylinveption.V One variation might be the forcing inward ofthe lugs '(2-7 toward the lO--ltlafteivthe,members 8-8 have been interlocked with theniembei' 1 there-` by. dep ending. on. `the lugs .7-7 `and. the flange 1.0 andthe parts 6,59 and to hold themembersS-Bandlthc member 1 ingposition and :without `.theassistanceof -the member 16 at all. y f
