WiTnessesn UNITED STATES PATENT OFFICE.
JOHN WILKIE, OF CROSSHILL, GLASGOW, SCOTLAND.
ELECTRIC COUPLING OR CONNECTOR.
- To 'all whom it may concern:
Be it known that 1, JOHN WILKIE, of 17 Albert Drive, Crosshill, Glasgow, Scotland,
electrical engineer, have invented certain new and useful Improvements in Electric Couplings or Connectors, of which the fol-v of a key whereby the nut may be conveniently operated to clamp and release the wires, and also in providing a suitable con-. tainer for the aforesaid parts whereby the complete connection is thoroughly insulated.
In order that my invention may be properly understood and readily carried into efiect, I have hereunto appended one sheet of drawings, of which- Figure 1 is an elevation of an electric fitting designed for a ceiling and comprising two connectors or metal cylinders embodying my invention, one of which is shown in section. Fig. 2 is a plan of the same. Fig. 3 is a plan of the connector or metal'cylinder with binding nut removed and showing two electrical wires looped or bent around the central post. Fig. 4 is an elevation of the said connector or metal cylinder with a key, engaging the head of the nut and an elec trical wire leading from the interior of connector or cylinder.
The connector or metal cylinder in one of its simplest forms is shown at A, said cylinder having a closed end or base A, an open end A, and side walls provided with a suitable number of slots (herein shown as four) E, F, G, H, through which the electric wires L to be coupled may pass from the exterior to the interior of said cylinder.
B denotes a threaded post arranged centrally of said cylinder and projecting from the base A thereof toward the open end A The ends of the wires L, after passing through the slots E, F, G, H, are given a suitable number of turns about the post B, as shown in Fig. 3, and are retained in position by a binding nut mounted on the post Specification, of Letters Patent.
Patented Mar. 16, 1915.
Application filed May 21, 1913. Serial No. 769,103.
B and adapted to clamp the ends of said' wires between itself and the base A.
The nut C is preferably of a circular form substantially fitting the interior of the cylinder .A and is normally located entirely within said cylinder. In order to operate the nut C to clamp or release the ends of the Wires L, said nut is preferably formed with a non-circular head or projecting portion C adapted for engagement by the slotted end D of a key D (see Fig. 4) of a suitable size to enter the cylinder A.
The cylinderA and parts associated therewith are inclosed in a container I composed of any suitable insulating material. Said container is preferably of cylindrical shape, is formed with an open end adjacent the open end A of the cylinder A, and is provided in its side walls with slots E, F, G,
H, corresponding-to the slots E, F, G, H.
' The exterior surface of the container I is preferably threaded to cooperate with a threaded opening in the usual ceiling bracket J or other support whereby said container with its inclosed coupling is se-.
cured in place in said bracket or support.
K denotes a threaded cap, also formed of insulating material, and adapted to engage the threaded surface of the container I, thereby closing the open end of said container and completely inclosing and thoroughly insulating the joint or coupling.
Claims:
1. An electric connector comprising a metal cylinder having a base, an open end, and side walls provided with slots, a centrally arranged threaded post projecting from said base toward said open end, a binding nut on said post, a container of insulating material inclosing said cylinder, said cylinder having slots registering with the slots in said cylinder and having an open end adjacent the open end of said cylinder, and a cap also of insulating material for closing the open end of said container.
2. An electric connector comprising a metal cylinder having a base, an open end, and slotted side walls, a centrally arranged threaded post projecting from said base toward said open end, a binding nut on said post having a projecting head within said cylinder formed for engagement by a key, a slotted container of insulating material inclosing said cylinder and having an open end adjacent the open end of said cylinder,
and a cap for closing the open end of said container.
3. An electric connector comprising a bracket having a threaded opening, a container of insulating material having a' threaded exterior, slotted side walls, and an open outer end, the threaded inner end of said container being received within said threaded opening, a binding post and nut within said container, and a threaded cap co operating with the threaded outer end of said container for closing the same.
4. An electric connector comprising a bracket having a threaded opening, a metal cylinder having a base, an open end, and side walls provided with slots, a centrally arranged threaded post proJecting from said base toward said open end, a binding nut on said post, a container of insulating material inclosing said cylinder, said container having a threaded exterior, anopen outer end, and side walls provided with slots registering with the slots in said cylinder, the threaded inner end of saidcontainer being received within the threaded opening in said bracket, and a threaded cap cooperating with the threaded outer end of said container for closing the same. 7
In testimony whereof I afiix my signature in presence of two witnesses.
