SWIVELING ATTACHMENT DEVICE FOR ELECTRICAL APPARATUS.
Application filed June 26. 1909. Serial No. 504.439.
To all whom, it may concern:
lie it known that. l, Jon'sll. MonLnY, a citizen of the. United States, residing in the city of Johnstown, in the county of Cambria and State of lcnus vdz'ania, have invented -certain new and useful Improvements in Swiveling Attachment Devices for Electrical Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it upper-terns to make and use the same.
My invention relates to swiveling attachments for electrical apparatus and is particularly adapted for ll'rP in connection with telephone receivers or suspended incandescent lamps. Its object. is to provide an attaching device which will be capable of rotation about; its axis and still maintain a good electrical contact.
My improved device is constructed so I that it may be attached or detached without twisting the wiresand it also prevents the twisting of the wires during use.
etc-t ring to the two sheets of drawings accompanying this specification, in which like. characters of referenceindicate like parts throughout the views: Figures 1, 2, 3 and 4: illustrate my device fully and par tially assembled and some of the uses to which it may be put. Fig. 1 is a. front elevation of a telephone receiver embodying my invention. Fig. 2 is aperspective view showing my device applied to the bell-box of a telephone. Fig. 3 is a side elevation of a lamp-socket: with my device in place but I not yet seci'ired against loosening. Fig. 4 is a side elevation of a wall tap with my der the scope of my invention, or as pointed out vice in position. Fig. 5 is a vertical crosssection through the upper part of the receiver and device shown in Fig. 1. Fig. 6 shows the removable p rt of my device assembled ready for insertion in the body part. Fig. 7 is a top plan of the swiveling part of the device: Fig. 8 is front cleva tion; and Fig. 9 a \icW of the bottom of the same. Fig. 10 is a top plan view of the body part. of the device.
Referring now to the drawings in detail. the plug 1. which is preferably of porcelain or other insulating material, is shown as carrying the branch wires 2 and 3, thewire 2 being connec ed to the arcuate metallic spring 4 and the wire 3 to the U-shapcd metallic spring 5 of \vlich there may be one or more. The threaded metallic sleeve 6 fits loosely over the plug and contacts with the arcuatespring 4. As is best shown in Fig. 5, the upper part of the sleeve 6 is formed into a. shoulder 7 which prevents the sleeve fromslipping oil the plug but permits it to turn easily. The cap 8 is screwed to the upper part of the plug and'holds the plug and sleeve together when detached from the body part.
The body part of the device, to which the attached, consists of the threaded sleeve 11 and the center contact 12. The wire 9 is connected to the sleeve 11 and the wire 10 to the member 12. The jam-nut; 13 is mounted on he sleeve 11 and is used to hold the rotated without loosening the other'parts of the device. The nut 14, also mounted on the sleeve 11, secures the device to the teleapplied.
To insert the plug 1 in the body part, the wires 2 and 3 are held stationary and the sleeve 6 is rotated until the spring is forced against the center contact 12. This stage of the operation is shown in Fig. 3. The nut 13 is then screwed tightly against the collar 15 on the sleeve (3, thus preventing the sleeve from becoming loose by; turning, although the plug and its attached wires may be turned easily.
Although I have shown and described my improvements in considerable detail, I do not wish to be limited to the exact and specific details shown and described, but may use such substitutions, equivalents thereof, as are embraced within in the claims.
Having thus described my invention, what Patent is: D

An attachment devlce com )rismg a plug earrving another. set of wires, said plug being inserted within the body portion and connected thereto by means of a spring on said plug a sleeve insulated from said spring and loosely surrounding the sides of the 1 plug to permit rotation. said sleeve being tcrinirial-carrying plug, said terminals conphone receiver or other object to which it is I body portion carrying one set 0 wires, '1 V Specification of. Letters Patent Patented Oct. 11, 1910,
wires 9 and 10 from thesource of current are sleeve 6. in place so thatthe plug may be modifications or I claim and desire to secure by Letters sisting of an a rciiate spring at the side and one or more U-shaped springs at the end of.
the plug, a metallic sleeve abutting the other end and loosely '-'\\l'l'()llll(lll g the sides oftheplug and contacting with the side terminal.
and a body )Olllllll eonsi sleeve electrically connected to one feed wire sting of a metallic and-contactingwith the sleeve surrounding sleeve contacting with'the side terminal, a
the plug, and a .inembcr electrically connected to the other feed wire and contacting 5 :tallie sleeve electrically connected to one a with the end terminal on the plu.
3. An attachment device comprising a ternnnal-ear ying plug, said terminals consistirg of an arcuate spring; at the side and one or more U-shaped springs at the end of the, plug, a threaded metallic sleeve abutting the other end and loosely surrounding the sides of the plug to permit rotation, sfiid sleeve contacting with the side terminal, and a body portion consisting of a threaded inctallie sleeve electrically connected to'onc feed wire and a member electrically connected to the other feed wire, said member being in contact with the end terminal on the plug and the threaded sleeve surrounding the plug being engaged by the threaded sleeve onthe body portion. v
4. An attachment device comprising a terminal-carrying plug, said terminals consisting of an arcuate spring at the side and one or more U-shaped sprii'igs at, the end of the plug, a threaded metallic sleeve loosely secured to the plug to permit rotation, said sleeve contacting with the side terminal, a body portion consisting of a threaded nietallic sleeve electrically connected to one feed wire and a member electrically connected to the other feed wire, said member being in contact, with the end te m nal on the plug and the threaded sleeve on the plug being engaged bythe threaded sleeve on the body portion, and means for preventing relaf tire motion between the two sleeves,
An attachn'ient device comprising a terminal-canylng plug, said terminals consisting of an arcnate spring at theside and one or more U-shaped springs at one end of the plug. a threaded metallic sleeve loosely secured to the plug-to permit rotation, said body portion consistingof a threaded mefeed wire and a member electrically connected to the other feed wire, said memberheing in contact with the end terminal on the plug and the threaded sleeve on the plug being engagedhythe threaded sleeveon the body portion, and ajani-nut for locking the sleeves in position.
(i. A. swiveling electrical connection comprising a termma l-carrying plug, the terminals eonsislin' of an arcuate s rin at the side of he plug and one or more U- sliaped springs" at the end of said plug, a metallic sleeve abutting the other end and loosely surrounding the sides of the. plug and contacting with tl ;e side terminal.
7. An electrical sivifeliiig connection com prising a t'erminal-cicrying plug, one of said terminals consisting of an areuate spring at thc'side of said plug, the other terminal consisting of one or more U-shaped springs at the end of said plug, a threaded metallic sleeve loosely surroun ing the sides of said ping to permit rotation. said sleeve- 5 contacting with the side terminal aforesaid. f lll'lBSl'llIlOll) whereof 1 hereto allix my sigiiatui'e in the presence of two witnesses.
