vISO
In Athe exemplilication of the invention shown in the drawings, an insulated hanger having a base flange 2 1s rigidly secured to any suitable support 3I by means of stud bolts 4 which pass through "the base flange Within theinsulator shield 1 is a mass of insulating material 5, in which is embedded a stud 6, having its'lower end members 7, 7 provided with screw threads, as shown in F igsrZ and 3. A trolley lineor conductor 8 is adapted to be engaged by a pair of clamping members 9 and 10, said clamping beingl provided with complementary recesses 11 and 12 to adapt said clamping members to receive a swivel heady 13 provided on the lower end of a member 14 havingI a screw socket therein. The swivel head 13 is separatedfrom the upper portion of the member 1,4 by a contracted neck l5; In order to provide means foA forcing the power arms 16 of the clamping members outwardly from each` other, so as to clamp Athe wire or conductor 8 therebeslidably mounted upon the member 14 and is provided withone or4 more -inwardly pro jecting lugs 18, whichslide in receiving reccsses 19 in the member 14, and which re-v cesses `open outwardly through the peripheral wall of the member. Thus connected it will be apparent that by rotating the collar or wedge l17 -in the propel' direct-ion, the member 14 will' be adjusted' upon the stud 7, 7a to force the clamping members upwardly. As the movement ofthe collar 17 shown. Onopposite sides of the recess 11,l
this clamping member is provided with a pair ofV trunnions 21.' Adjacent the inner end of each of said trunnions 21 is a later ally projecting lug 29.. The other clamping member shdwn in Fig. 7 comprises aa similar clampir g jaw 20 and a power arm 1G, and on opposite sides of the recess 12 the curved lateral lwall of thev clamping member is provided with recesses 23, into which the Vtrunnions 21 of` the other clamping memberare adapted to be inserted. EX-
tending across the recesses or apcrtures,23
on the comcalslde of the lateral wall'of tween, an expanding collar or wedge 17 isower arms 16 to effect a clamp!` The clamping member as tures 23 is of such a shape as to leave a lug or shoulder 25 adj aeent the recess l2, Then the members are assembled, the lugs 22 of one clampingr member are adjacently dis posed to the lugs 25 of the other clamping member, but are outside of the same. Said clano'iing members are then adapted. to be assembled or separated at Will. Whenit is i desired on the other hand to lock the clamping members together and against accidental displacement, the lugs 22'rnay be bent inwardly into such position that they Will be Abrought Within the shoulders 25 When the clamping members are cscillated relatively to eachother, and thereby hold the trunnions,within the respective sockets. Consequently, the clamping members will be held in such relative position as will prevent them from being disassembled.
What I claim is:
l. ln a. trolley line clamp, the combination with a pair or' clamping members provided with complementary recesses for the reception of a .suspension member, one of said clamping members being provided With a curved lateralgvall having spaced passages th rethrough and a4 convex shield or apron extending over each passage on. the concave side of said lateral Wall to ferm journal sockets, the said shields being of a size less rosee-ee than ,the Lrespactive passages," thefother or said clamping members being p rovlded with journal lugs adapted tobe inserted through said passages into saidsockets, saidv curved lateral Wall of the one member being provided with recesses opening from said apertures forming shoulders and the trunnions of said other member being provided with lugs projecting into said recesses.
ln. a trolley line clamp, the combination with a pair of clamping members pro vided with complementary recesses for the reception of a suspension member, one of said clamping members being provided With a curved lateral Wall having spaced passages therethrough and a conv-es shield. or apron extending over each passage on the concave side of said lateral wall to form journal sockets, the said shields being of a size less than the .respective passages, the other of said clamping members beingl provided with trnnnions adapted to be inserted through said passages .into said sockets, said curved lateral wall oit the one member being provided `with recesses from said apertures forming shoulders, lugs projecting into said recess said lugs being capable of being bent into a position locking the clamping members against separation.
ln testimony whereof l have signed .my name to this specification, in the 'presence ottivo subscribing Witnesses, on this 30th day et November, l). i910.
