' LEAD-K1N CONNECTION,
Application filed October 14, 1924. Serial No. 743,597.
This invention relates to lead-in connections for wireless outtits and has for its object the provision of a neat, simple, compact device adapted to be applied to therwall oi' the room whereby a receiving set may be readily connected or disconnected with the ground and .antenna wire.
A further object of the invention is the provision of a unitary structure for providing connections for the ground and antenna wires and which are properly insulated from each other and troni the building through which the wires are ordinarily inserted.
This invention will be best understood from a consideration of the followingv detailed description. in view of the accompanying drawing formi-ng a part ot the specification; nevertheless it isto beiunderstood that the invention is not confined to the disclosure, being susceptible et' such changes and modiiications which shall define no material departure from the salient features of the invention as expressed in the appended claims. Y
In the drawings:
Figure 1 is a view in perspective of a receiving set and my lead-in connections at-V tached to the wallet a room. n
Figure 2 is a front view ot the same. 3U Figure 3 is a horizontal section of the lead-in connections.
VReferring more particularly to the drawings the device consists of a plate 1 formed of bakelite or any other insulating material which is perforated at its corners to receive screws 2 for attaching the plate to the wall ot the room. At spaced points the plate'l is further perforated through which isY inserted conducting rods 3 andk 4. The conducting rod 3 is threaded as shown at 5 to receive a knurled nut 6. The lock nut 8 is adapted to be engaged by the threads ot the rod 3 and cooperating with a nut 7 on the opposite end of said rod :tor locking the rod in rigid relation with the plate 1V through the medium of an insulating sleeve 9. Tie
sleeve 9 as shown has a longitudinal passage through which is inserted the rod 3 and with the sleeve being inserted through an opening 10 in the wall 11. The nut 7 engages the outer end of the sleeve 9 while the nut 8 clamps the plate 1 in rigid relation with the sleeve 9. The outer end of the rod 3 is provided with a knurled nut 12 whereby the ground wire is clamped upon the nut 7 on the conducting rod 3 beyond the outer 'ace of the building. l Y
A wire 22 which is clamped by the nut 6 to the nut 8 is connected to the antenna binding post 14 of the receiving` set 15. The
ground binding post 16 of the receiving set is connected by a. wire 13 to the conducting rod 4 by means of a knurled nut 17 and a lock nut 18 engaging the threaded end oi* the rod 4. Y A
The rod 4 is' insulated from the wall 11 of the building by means of an insulating sleeve 19 and a lock nut 20 cooperates with nut 18 in clamping the rod 4 and sleeve 19 to the plate 1. A knurled nut 21 cooperates with the nut 20 for locking the tree end ot' the antenna leadin wire in conducting relation with the rod 4. y n Y It will be seen by the construction just described that a veryv neat lead-in connection is provided and also a means whereby a receiving set may be readily connected with the antenna and groundV with little or no trouble.
What I claim is:
A lead-in connection comprising a plate of insulation substance, a pair ot conducting rods passing perpendicularly through said plate in spaced relation, an insulating sleeve embracing each rod, and abutting against the rear tace of said plate, nuts on the opposite ends of the rods for locking the insulated sleeves in rigid relation with the front plate and binding nut-s on the opposite ends of the lrods tor securing the usual connections to the conducting rods. y
