ELECTRIC FITTING.
Specification of Letters Patent.
Patented Mar. 26, 1918.
Application filed February 16, 1817. Serial No. 148,936.
To all whom it may concern:
Be it known that I, Gnoncn C. KNAUFF, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and uscful Improvements in an Electric Fitting; and I do hereby declare the following to e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to electric sockets or connectors, its general objects being to provide an unusually simple and practical construction for W'tWo-Wire single-polc a Jpliance of this kind. In electric fittings 0 this general class as used in connect on with automobile lighting circuits, the s )ace limitations within metal casings whic are proportionate in size to the lamps designed for this purpose make it diflicult to insure good electrical connections with simple and inexpensive constructions. Thus, to accomnio date the two Wire terminals within the linr itcd space, it is necessary to place both of these out of alin ement with the axial terminal required for contacting with the cor responding terminal on a lamp or a con nector plug, so that an electrical connection must be provided between the said axial socket terminal and one of the wire termi nals. Such a connection is shown in U. S. Patent No. 1090629, issued to me March 17, 1914, in which I employ a spring-pressed plunger for this purpose.
My present invention aims to simplify this construction by reducing the number of parts, and to improve the resulting electrical connections by entirely eliminating oijie of the contact junctnres required with construction disclosed in my said issued patent. I accomplish this partly by 1naking one of the wire-terminals integral with the axial socket terminal, or at least with the casing of the latter, by equipping at least one of the adjacent insulating elements with a transverse recess, and otherwise after the general manner disclosed in the following specification and in the accompanym drawings, both of whiclf'will disclose furt er objects of m invention.
In the rawings,
Figure 1-is a central lon 'tudinal section through afiampsocket em odying my in- VBDtiOlL Fig. 2 is a transverse section, taken along the hue 22 of Fig. 1.
ducting element of the socket of Fig. 1.
Fig. 4 is an elevation of the same before the ofiset is formed in it. I Y
Fig. 5 is a central longitudinal section through a connector plug embodying my invention.
In employing my invention in a socket for a so-called single-pole lamp (that ip t6 say, one having a single terminal exposed on the end of its base, the other connection being made through the shells of the lamp and socket), I desirably use a substantially cylindricah casing 1 equi ped at one end with bayonet slots 2 for interlocking with pins 3 on the base of the lamp 4. Mounted within the casing 1 are two insulators 5 and 6 (of hard rubber or the like), the former of which has a central bore part1 housing a metal cylinder 7, which cylin er partly houses a spring-pressed contact plunger 8 adapted to engage the axial terminal 9 of the lam The companion insulator 6 is ing two Wire terminals 10 and 11, and also has at its inner end a transverse recess 12 adapted to connect one of the said bores with the axial bore of the insulator 5. This transverse channel or recess houses a connecting element 14 for carrying the current from'the wire terminal 10 to the plunger cylinder 7 and is preferably made integral with both of the latter. For this purpose I first machine all three of the said elements in alineinentwith each other, as shown sectionally in Fig. 4. Then I form an oflset in the portion 14 which is considerably smaller in cross-section than the parts connected thereby, thus forming the portion W into a substantial] Z-shaped connecting element. In assembing the socket, the forward insu1ator..5 may first be anchored in the casing 1 by any suitable means, as by indenting lugs 22 into the said insulator. hen the composite conductor shown in Fig. 3 is slipped into its normal position, the rear insulator 6 is slid over this into place, the
and finally both the latter terminal and'the insulator 6 are anchored by inserting the screw 13 which electrically connects the" wire terminal-1,1. with e of the proportioning the depth of the recess 12 and the shape of the connecting element, 1%, this element will engage the rear wall of the re cess, so that the said composite conductor will require no auxiliary Iastenings to hold the same in position.
However, my construction might be moditie Lin many ways without departing from the spirit of my invention. For example, Fig. 5 shows a connector plug in which the composite eomlucting element is held in of)- erative position partly by the screw 15 which secures the wire 16 to the terminal 10, and also shows the forward insulator 5 asheld in place by the contracting of the forward end of a metal shell 17 grounded to the other terminal 11 by a screw 18.
In either case, it will be evident that my construction obviates both spring contacts and other contact connections between the wire terminal 10 and the plunger cylinder 7 thereby reducing the required number of parts and insuring a good electrical connection between the said wire terminal and the cylinder housing the plunger which contacts with the axial lamp terminal. In practice, I have found that offset; bends of the types shown can readil be formed in turnings made of ordinary Jrass rod, hence my construction also requires no departure in materials from those heretofore used for this class of goods.
I claim as my invention:
.1. In an electric fitting, a casing, a pair of insulating bodies mounted therein and equipped with relatively unalined bores extending longitudinally of the casing; and a eondurting member comprising in rigid formation it ire terminal and a plungercylinder hou ed respectively by the bores oti said bodies. and a connecting element ex tending substantially il'illl \'t:'lt-$Ul f the asing and housed by one of said bodies.
In a tilting of the eh s described. a conducting member comprising in integral formation a wire terminal. a contact terminal, and a substantially zshaped core neeting element; a pair of insulators equipped with nnalined bores respectively slidably entered by the said wire terminal and contact terminal portions of the conducting member; a casing housing both of the insulators; and means associated with the, casing for holding both insulators rigid.
within the easing.
3. 1n au'eleetrir lilting. a substantially cylindrical easing. a pair of insulating bodies mounted therein. and a conducting, member carried jointly by said bodies; one of said bodies having a bore axial ot' the ca. lllg and the N 'tllltl l) lll having u bore (7(- tendin longitudinally of the raising but out of alinenn-nt with the axis of the latter, and one of said bodies having a recess connecting the said bores: the said member comprising a conluet portion housed by the said axial bore. a wire terminal portion housed by the other bore, and a. eonneeting element rigid with both of the said portions and housed by the said recess.
