Nov. 4 1924 J. BLACKBURN SOCKET Filed Dec. 27. 1920 In z/em Zorn afasper 5 2a c/(um Patented Nov. t, 1924.
UNHTEE fiTA'iES JASPER BLACKBURN, OF ST. LOUIS, MISSOURI.
SOCKET.
Application filed December 27, 1920.
To all whom it may concern:
Be it known that I, Jnsrnn Bmonnnnn, a citizen of the United States, and resident of the city 01": St. Louis and State of Missouri, have invented certain new and useful improvements in Sockets, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings forming a part hereof.
My invention relates to improvements in electric sockets and has for its primary object the construction of a socket molded out of bakelite or other insulating material, and in the process of molding the terminals or the screw threaded socket and the central contact are secured and held in place, the one part of the socket being formed separately and inserted in place after the socket is molded is the key for operating the switch.
In the drawings:
Fig. 1 is an elevation.
Fig. 2 is a longitudinal section.
Fig. 3 is a top plan of the socket with the cap removed.
Fig. 4. is a plan view of an insert, which I employ.
Fig. 5 is a side elevation of the same.
Fig. 6 is a plan view of the key.
Fig. 7 is a side elevation of the screw threaded socket with parts broken away and in section. 1
Referring to the drawings, 8 indicates the body portion of the socket, which is molded or formed of bakelite or any other suitable insulating material and is provided in its upper portion with a central opening or recess 9. 10 indicates the metal screw threaded socket around which the body of bakelite or other material is formed. This metal screw threaded socket is held in place by molded material. 11 indicates the spring contact. which is also molded in the body 8, the yielding or resilient end 12 extending down into the socket to electrically engage with the plug inserted in the socket. The upper end 13 of the conductor contact 11. extends into the recess 9 and is positioned against the stem 14 of the switch key. By turning the switch button 15 the current may be turned off or on as desired. Molded in the body 8 are terminals 16 in which are seated binding screws 17 by which the electrical conductors 18 may be secured to the terminals. Screw seated on the upper end of the body 8 is a cap 19 provided with Serial No. 433,162.
opening 20, through which the electrical conductors 18 may be inserted. Surrounding the opening is a collar 21, which may be, if desired, internally or externally screw threaded, by means of which it may be attached, if desired, to a lighting fixture; or if desired, it the collar 21 is externally screw threaded a finishing cap provided with internal screw threads may be applied.
To apply the switch key, in the manufacture of the socket a removed portion or recess 22 is provided within which an insert 23 may be seated. This insert 23 is provided with a stem 24: adapted to be inserted in the recess 25, and said insert is further provided with a vertical slot 26 and groove 27. The groove 27 is adapted to receive the tongue 28 formed on one wall of the recess 22. Formed in the opposite wall of said recess is a vertical recess or depression 29 adapted to receive a disc 30 formed on the switch key shank. The inner end of the switch key shank is seated in a bearing 31 formed in the body portion 8. In order to apply the switch key the insert 23 is first removed and then the key is inserted, as described, and the insert is then replaced, and by screwing down the cap 14 the insert is held in place.
It will be observed that the upper edge of the insert is cut away so as not to interfere with the screw threads formed on the inside of the cap.
From the foregoing it will be observed in the molding of my device out of bakelite the conductors, contacts andterminals are securely imbedded and moulded in place and all that is necessary to do is to insert the switch key and binding screws, as previously described. The metallic screw threaded socket 10 is provided with a projection 32, which leads to one of the terminals 16. It will be noted from my construction that all of the parts are moulded in position. In other words, secured within the socket without any additional fastening means. The only screws used in my device are the binding screws 17, by which the electric conductors are secured to the socket.
Having fully described my invention, what I claim is:
A socket comprising a body of insulating material having a central recess formed in its upper end and a portion of the wall surrounding said recess removedso as to form a gap, one vertical edge of said gap provided with a tongue, the other with a semi-circular recess, an 'arcuate insert adapted to fit within said gap, said gap provided on one edge with a groove to engage with said tongue, its opposite edge with a groove adapted to come in alinement with the semicircular recess, a centrally located spring contact molded in said body, its one end extending into the central recess, a screw threaded metallic socket molded in the lower end of said body of insulating material and surrounding the lower end of the spring contact, an L-shaped projection formed integral with said screw threaded socket and extending through the upper end of said body of insulating material, a binding screw carried by said projection, a contact having a binding screw carried by the upper portion of the body of insulating material, and adapted to be contacted with by the spring contact, a switch key for operating the spring contact, a disk carried by the switch key adapted to enter the semicircular'recess and the groove in aliiieinent therewith for holding said key in position, and a cap adapted to be secured over the upper end of the body of insulating material for holding the insert in position and preventing accidental contact with the binding screws.
in testimony whereof, I have signed my name to this specification.
JASPER BLACKBURN.
