Pulling Clnmps, of which the following isn specification.
M invention relates to n cnble or wirepulllng'chunp` of the type technically known ns n come-nlong." i, r
These devices nre used principally by line men in the construction und repair of electric L runsniission lines, and are. fre uently operated underthe most difficult conditions, as, lfor example, by n lincnmn elingin to the top of n. pole', or sitting or stan ing upon .n '-ro'ssV arm many 'feet above the ground. The ideal clump for `such use is one that is :is light ns is consistent with the ncceury strength, which muy be operated .entirely -by one hund, und which can he tightened upon the wire with comperanA tively little e'ort n.nd when Aso ti htened will establish u. suliicient gri upont 1e wire to picventslipping even un er the greatest strains used in practice.4 In this connection it is well to note that the normal strain. upon* un -aericl power conductor, in the systems using long spans between supports, may :l mount to 3000 pounds or over, nnd'tlntt the pnl] upon c chimp, when Stringing;I or4 rcpniring such' u cable, may rcuch 4000 pounds. The object or' my invention is to provide n clump having the desirable features nientioned above. In addition, my clump is of such construction tlm-t the clampingr effect on the wire does not depend on the pull on the clump, so that the hitter mcy bc loosened, to permit the wire to he slil'ipcd through it, without relieving thel pulling strain.
further advantage ofy my chimp resides in' .the fact that it may be readily. dissocinterll iso for the replnccinent or rep-nir olt iiny of its parts.
lVith these and other objects in View, my invention will now he described in its preerred forni, but it is to be understood that changes, withinthe scope of the claims hereto appended, nniy he made in the forni und construction of? the device without depnrting from the spirit of the invention.
In reading the following description, reference should be hud to the uecoiupnnyiu'g drawings, whereinw Figure. l is n side elevation of my clump attached to c )vile or cable. F ig. 2 is o front elevation of the cliunp, enlarged, showingthe ports in position for application to n.' wire or'euble. Fig. 3 is 1in-end elevation of the chimp :is shown in Fig. 2.
'Figl e is u truusvcrse section, enlarged, token on` the' linie .l-l of Fig. l, the wire being omitted.
In the drawings, the reference numerals 1 and l designate thetwo :idjncent eo-uet- 'ing )uws .of my clump, which 'ure hinged togather :itfone side by a pin 3, passing through adjacent intcrtitting curs 4 und of 'sind Jaws 1 and 2 respectn-'elin The inner.l
