CHARLES L. HOPKINS, OF RIVER FOREST, ILLINOIS, ASSIGNOR TO BENJAMIN IEJILEG-A TRIO MANUFACTURING COMPANY, F CHICAGO. ILLINOIS, A CORPORATION OF ILLINOIS.
ELECTRICAL CONNECTER.
Application led J'une2. 1922. Serial No. 565.359. Renewed November 6, 1924.
To al? whom it may concern:
Be it known that I, CHARLES L. HorKrNs,
a citizen of the United States, residing at River Forest, in the county of Cook and State of Illinois, have invented new and useful Improvements in Electrical Connecters, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
My invention relates to electrical connecters and more particularly to swivel attachment plug caps for use with standard separable attachment plugs and which may be used in connection with adapters, receptacles, etc.
One of the objects of my invention is to provide a swivel attachment plug cap which may be adapted for use with the standard attachment plug and by means of which the attachment plug may be screwed into the re ceptacle without twisting the conducting members.
Another object of my invention is to provide a swivel attachment plug cap for use with any ordinary separable attachment plug and provided with an extension handle whereby the attachment plug may be inserted in places which are diiicult of access, withouttwisting the electrical conductors.
Another object of my invention is to provide an attachment plug cap which will be easy to assemble, eiicient and durable in use, and cheap to manufacture.
Further objects will appear from the detailed description to follow and from the appended claims.
In the drawings in which an embodiment of my invention is shown:
Figure l is a vertical longitudinal section through an attachment plug cap, the body or receptacle part of a standard separable attachment plug being shown in connection therewith by dotted lines;
Fi 2 is a top plan view of the base of the attac l ment plug cap with the swiveling disc and handle removed and the blades and other parts in operative position;
Fig. 3 is a top plan view of the attachment plug cap;
Fig. 4 is a side elevation of the cap taken in the direction of the arrow in Fig. 1; and,
Fig. 5 is a plan view and Fig. 6, a side view of the spring washer.
Referring now to the drawings in detail,
in my invention as illustrated, I rovide a base 10 corresponding to the or inary attachment plug cap base and provided with an opening 11 therethroughl to receive the conducting members. The upper part ot' the base is provided with an opening 12 in which the connecter blades 13 and 14 are secured in electrical connection with the binding plates 15 and 16 respectively. The binding plates 15 and 16 are secured to the ba e 10 by means ot the hollow rivets 17 molded into the base 10, and are provided with the binding screws 18 and 19. The binding plates 15 and 16 are provided with the overlapping portions 2O and 21 respectively. These. overlapping portions are separated and insulated from each other by means of the insulating washer 22. The
A spring washer 26 is insertedbetween the binder plate 16 and-the insulating washer .22 and all of these superposed parts are secured together by means ot the threaded eyelet 27, the insulating washers 22 and 25 also serving to insulate the blade 13 and the binder-plate 15 from the threaded 'eyelet 27 as illustrated in Fig. l, the eyelet 27 being tightened sufii ciently to secure all of the parts in movable relation with each other, the spring washer 26 serving to hold the members securely in frictional and electric-al contact.
An insulating disc 28 is provided having openings 29 therethrough through which the contact blades 13 and 14 extend. The insulatin disc 28 i's rotatably mounted on the base tby means of the shouldered screw 30, which is screwed into the threaded eyelet 27, the shoulder 31 being tightened against the threaded eyelet, thus locking the screw securely in place and allowin .for the free ro tation of the insulating disc 28. A sheet metal .ring 32 is secured to the insulating disc 28 and is provided with the downwardly extending ears 33 on whichv a U-shaped han dle 34 is pivotally mounted Aby means of the eyelets 35. The ears 33 are also provided with holes 36, the handle 34 being formed at 37 to engage the edges of these openings for the purposev of holding the handle in impositive longitudinal relation with the cap. In use, the conducting wires are inserted through the hole 11 in the base 10 and secured to the binding plates by means of the binding screws 18 and 19; the blades 13 and 14 may then be inserted in the receptacle portion of any ordinary separable attachment plug as illustrated at 36 by dotted lines; thel plug may then be inserted in a deep shade or any receptacle which would be difiicult of access with the ordinary plug. It will be noted that in the construction as illustrated, the insulatingmember 28 may be rotated by means of the handle 34, vthe disc in turn rotating the blades 18 and 14 around the axis of the attachment plug cap, and the plug 36 carried by the blades 13 and 14 may be easily screwed into or out of the receptacle, the pivoted handle may then be moved to any desired angular position, so that it will not interfere with the free movement of the electrical conductors during use. While I have shown but one form of my invention it is obvious that -it may be embodied in other forms as covered and defined by the appended claims. t
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. An attachment plug cap comprising an insulating base having an opening therein, overlapping binding plates mounted in said opening and insulated from each other, conducting blades mounted for free vrotation on said overlapping portions and insulated from each other, each of said vconducting blades being electrically connected to its corresponding bindingl plate, and a freely rotatable insulating member mounted on said overlapping plates for rotating said blades.

9. A separa le attachment plug ca comprising contact blades for engagin t e contacts of a receptacle portion o a plug, wiring terminals for said blades, and an insulating base on which said wiring terminals and contact blades are mounted, said cap having means providing for relative swiveling between said contact blades and wiring terminals about an axis extending longitudinally of the blades, whereby the bla es and receptacle portion of the plug can be screwed into a socket without twisting the wires secured tof` said wiring terminals.
10. A separable attachment plug cap comprising contact blades for engaging the contacts of a receptacle portion of a plug, wiring terminals for said contact blades, and an insulating base on which said wiring terminals are mounted, said blades being swiveled with respect to said -insulating base about an axis extending longitudinally of the blades, whereby the blades and recan be screwed into a socket without twisting the wires secured toy said wiring terminals.
11. A separable attachment plug cap comprising contact blades for engaging the contacts of the receptacle portion of a plug, wiring terminals for said blades swiveled with respect to said blades, and an extenl sion handle provided with means whereby said blades may be given a swiveling movement with respect to said wiring terminals, whereby said blades and receptacle portion of the plug can be screwed into a socket without twisting the wires secured to said l Wiring terminals.
12. A separable attachment plug comprising a screw-threaded body portion for screwing) into a socket, and a cap having Contact ades for engaging the contacts of said body portion, and wiring terminals for said blades swiveled 'with respect to said blades whereby the blades and bod p0rtion of the plug can be swiveled with lrespeci: to said wirin terminals, whereb the body portion of te plug can be scrwed into a socket without twisting the wires secured to said terminals.
