- Application med December 2s, 1,923.. serial No. 6s3,v157.
.To all 107mm it may conc-era. I Be it known that I, JOHN M. JOHNSON, a citizen of the United States, residing at y Kansas City, in the county ,ot *Jackson and State of Missouri, have invented certain newr and useful Improvements in Swivel Couplings, of which-the following is a specilication. j
My invention relates to swivelcouplings and my object-is to vprovide a device of this character whereby circuit wires and various electrical appliances, such for instance, as telephone transmitters and receivers, electric lamps, etc., may be connected without twisting' the associate wires.y
Other Objects will hereinafter appear, and in order that the invention maybe fully understood, reference will now bevhad to the accompanying drawing, in which:
Fig. 1 :is an elevation of the device.
F ig. 2 isan enlarged vertical section on line II-II of Fig. 1.
Fig. 3 is a cross section on line III-,III oit Fig. 2, l i
F ig. 4 is a cross section on line IV-IV of F ig. 2. Y
y In carrying out the invention, I employ an inner conductor 2 provided at one end with a terminal 4 having' suitable means such as a binding screw 6 whereby a circuit wire A may be connected to said terminal 4. A portion of the inner conductor 2 is surrounded by an insulator 8 upon which a tubular conductor 10 is mounted, having one end abutting a shoulder 12 on said insulator 8. The tubular conductor 10 is provided at one end with a terminal 14 having suitable means such as a binding' screw 16 whereby a circuit rwire B may be connected to said terminal 14. I
18 designates a second tubular conductor free to rotate upon and having one. end abutting an annular shoulder 20 on the tubular conductor 10. The tubular conductor 18 is separated from the inner conductor 2 by an insulatorl 22, against which a metallic plate 24 abuts.
The inner conductor 2 extends through the plate 24 and is provided at one end with a collar 26 between which and said plate 24 a coil spring 28 is interposed. The spring 28 presses upwardly on the plates 24 and downwardly upon the collar 26 and thus yieldably holds` the tubular conductor 18 against the shoulder 20 of the tubular conductor 10 to insure a good contact between said tubular conductors and atfthe same time permit them.. to ,rotate independently of eachother. v, i
30 designates a inetalliccap connected to the metallic .plate 24 and surroundingthea spring 28, the collar 26 and the associate end of the inner conductor` 2. The cap 8() is providedv with a pole 32 which" extends through one end of an insulator plug 34 enclosing the tubular conductor 18, the insulator 22, the metallic. plate `.24 and said cap 30. The lower portionotthe insulator plug is sheathed in a screw threaded conductor 86 which is in circuit'with the tubular conductor 18 through the intermediacy ot a conductor 38.
.40 designates a shell, preferably, ofinsulating material threaded upon the upper end of the plug per end with an opening 421through which the wires A and B extend. i y i 34 and provided at. its upv- IV ith the parts constructed and arranged, il
as above describedit is apparent that `when the plug 84 yis rotated to screw it into a socket (not shown) thatthe tubular-con ductor 1,8 will rotate uponthe tubular con# ductor 10, thereby permit-ting thelatterwith itsterminal 14 and theinner' conductor` y2f stationary,
with lits terminal 4 to remain so that the wires Aland B will t i not become twisted as wouldbe the case if said termi nals 14 land 4 Should rotate with the plug 34.
W hen the plug 84 is screwed ,into alamp socket and the wires A and B are connected to an electrical appliance, such, for instance, as a motor, the current will pass from one pole of said Socket through the conductors 36, 38, 18 and 10, terminal 14, circuit wire B, the motor not shown, and' 'return to the socket, not shown, through the circuit wire A, terminal 4, inner conductor cap 80 and pole 32.
From the foregoing description. it is ap parent that I have provided a Acoupling embodying the advantages above pointed out, and while I have shown and described 'the preferred construction, combination and arrangement of parts I reserve thel right to make such changes as properly fall within the spirit and scope of the invention as claimed. l
Having thus described my invention, what I claim and desire to secure by Letters Pat ent,is: y
1. In a device of the character described an inner conductor ladapted to be connected 2, plate 24,
