To rr/ 11i/mm if may concer/1f:
lie it known that I, JouN J. Dossnu'r, a citizen of the United States, and a resident ol New York, county of New York, State ol New York, have invented certain new and useful Improvements in Branch Couplings for Electricv Conductors, of which the following is a. specification.
My invention relates to improvements in branch connections for covered electric cables.
'lhc object is to provide a connection which can readily be applied to any such cable. for making a branch connection without, severing the wires of the cable and Without causing by its application any abrasion of the wires or crimping of the cable.
'lhe invention is here illustrated in two forms, one embraced in-the 'lirst five iigurcs ol` thc drawings and the other in Figures to ll), inclusive.
Fig. 1 is an elevation of my improved branch coupling applied to a covered electric cable. Fig. 2 is a. cross-section along the. line 2 2 in Fig. 1. Fig. 3 is a detail longitudinal sectional view through the clamping-hook and its shank. Fig. 4 is a. detail sectional view taken on the line 4 4 of Fig. 2. Fig. 5 is a. perspective view of the movable clamping member. Figs. 6 and 7 are views correspending to Figs. 1 and 2, but relating to a modi'licd form oi coupling. Fig. 8 is a view in rear elevation of the coupling-hook, and Figs. S) and 10 show details.
Referring to the iirst 'figures of the drawings, 1 is an electric cable made up o1 a number of strands of Wire, and 2 is an insulatingcovering therefor. In applying my branch connection the insulating covering is removed for a short distance, practically corresponding to the Width or length of the coupling, Whereunon the coupling is applied to both sides oll the bared portion of the cable and securely attached thereto.
The elements of the coupling grasp the4 barcd conductor on directly opposite sides of the latter, and the pressure exerted upon the coupling members in securing the same in place are exerted radially with relation to the cable or other conductor to which the coupling is applied. One element of the coupling consists of a hook 3, which can bc placed over the conductor, and another element consists of a detachable cooperating segment 4 below the hook 3 and the member 4 being shaped to iit closely around the conductor on opposite sides thereof. The hook 3 is provided with an opening 5, which admits an extension G on the member 4 far enough so that the said extension can be pressed evenly by a nut 7,4 engaging with a scrmv-thrcaded extension ol the hook 3. This extension or shank is long enough to receive also a coupling member S, by means of' which a branch conductor S, covered or not, as may be, by an insulating-covering l0, .may be `ioined to the main conductor 1.
ln applying the coupling the hook 3 is 'first caught over the conductor l, and the segment 4 is thon put in place by passing the cX- tension G into 'the opening 5. lli/hen the coupling-segment is fully inserted into position, the nut 7 is screwed against the end ot' the extension 6, thereby compressing the conductor 1 between the members of the coupling.
By the construction of the coupling-hook 23 and segment 4 above described it will be apparent that the segment is removable from the shank ol" the hook by a lateral movement with relation thereto, which permits the removal of' the segment Without removing the clamping-nut from the shank of the hook.
It will be understood that the main conductor may be either a cable or a single Wire and that the saine is true of the branch conductor.
l/Vhen it is desired to couple to a main conductor a Wire or cable of smaller diameter, I prefer to use the form of coupling illustrated in Figs. 6 to 1l), inclusive. Here the hook 13 is provided with a small screw-threaded shank, as shown at 11, While the segment 5, with its extension 6, is replaced by a coupling member 14, which is provided With a curve 12 to receive one side o1 the main cable or conductor and also with a curved portion at right angles to the curve 12, as illustrated at 20, to receive a portion of' the shank 11 of the hook 13. ln other Words, the coupling meinber 14 is shaped so as to partly surround a portion of the shank 11 above the screw- 'threads and at the same time to it one side of the main conductor or cable 1. In this forni it will also be apparent that the movable jaw or segment of the coupling is removable 'from the coupling-hook by a lateral movement with relation to the latter.
IOO
. As beloie, the bottom of the member which cooperates with the hook is firmly and evenly pressed by a nut, which in this i nstance is designated by the number 17, while a coupling element 18 is attached to the bottom of the shank 1 1 to-receive a conductor 19, usually covered with an insulating-covering, as shown at 30.
The mode of attachment of the coupling shown in Figs. 6 to 10 is first to attach the hook 13 to the conductor 1, then insert the coupling member 14 in place, and afterward apply pressure through the medium of the nut 17, whereby a firm, mechanical, and good electrical connection is formed between the coupling and the bared conductor.
I claim as my invention- 1. lA branch coupling for electric conductors consisting of a hook provided with a shank, said hook constituting one member of a clamp, a member mounted on said shank, and formed with a clamping portion directly opposed to said hook, said member being movable to bring said clamping portion'in clamping relation to the hook, means Whereby said member is removable from the shank by lateral movement with relation thereto and means on the shank to move said member.
2. A branch coupling for electric conductors, consisting of a hook provided with a shank, said hook constituting one member of a clamp, a member slidably mounted on said shank and formed with a clamping portion directly opposed to said hook, said member being movable longitudinally of the shank to bring said clamping portion in clamping relation to the hook, means whereby said member may be removed from the shank by a lateral movement with relation thereto and means on the shank to slide said member.
3. A branch coupling for electric conductors consisting of a hook provided with a shank having a longitudinal opening therein, said hook constituting one member of a clamp, a member slidably disposed in said` opening and laterally removable therefrom and formed with a clamping portion directly opposed to said hook, said member being movable longitudinally of the shank to bring said clamping portion in clamping relation to the hook and means on the shank to slide said member.
4. A branch coupling for electric conductors consisting of a hook constituting one member of a clamp, provided with a threaded .shank having a longitudinal opening extending entirely through the same from side to Si e,` a member slidably disposed in said opening and removable therefrom by lateral movement with relation to the shank, said member being formed with a clamping portion directly opposed to said hook, and a nut on said shank for moving said member longitudinally of the shank to bring the clamping portion in clamping relation to the hook.
5. A branch coupling for electric conductors, consisting of a shank provided with a clamping-j aw at one end, a clamping member slida ly disposed on the said shank for movement toward and away from the jaw, means whereby said member is separable Jfrom the shank by lateral movement with relation thereto, and means carried by the shank to move the clamping member.
6. A branch coupling for electric conductors, consisting of a Vhook provided with a shank, said hook constituting one member of a clamp, a member slidably mounted on said shank and having a clamping portion to cooperate With said hook, and means whereby said member is removable from the shank by a lateral movement with relation thereto, and means to hold said member in clamping position.
