CHARLES J. MALISH, OF TOLEDO, OHIO, ASSIGNOR OF ONE-HALF TO LOUIS BERGMAN, OF TOLEDO, OHIO.
WALL-PLUG FOR INCANDESCENT ELECTRIC LAMPS.
SPECIFICATION forming part of Letters Patent No. 792,225, dated June 13, 1905. Application filed October 31, 1904. Serial No. 230,644.
To rtZZ 1072/0727, it may concern:
Be it known that I, OnARLns J. lNIALIsn, a citizen of the United States, residing at T- ledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in 'all-Plugs for Incandescent Electric Lamps; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
In the use of incandescent electric lamps in connection with wall-sockets or lamp-fixtures of the ordinary construction, the lamp being connected with the extremities of flexible conductors, a familiar difiiculty is the twisting and tangling of the flexible connections.
My invention relates to a wall-socket connection for incandescent lamps which shall obviate this difficulty and in which the socketpiece may be screwed into connection with a wall-socket or like fixture without turning or twisting the lamp or its flexible connections. I attain this object by means of the devices and arrangement of parts hereinafter described, and illustrated and shown in the accompanying drawings, in which Figure 1 is a side elevation of my device assembled and arranged for connection with a wall-socket or similar fixture; Fig. 2, a central longitudinal sectional elevation of one of the parts hereinafter referred to; Fig. 3, an end elevation of the same seen from the left in Fig. 2; Fig. 4, an end elevation of the same seen from the right in Fig. 2; Fig. 5, a central transverse sectional elevation of another part of my device hereinafter referred to, and Fig. 6 an end elevation of the same seen from the right in Fig. 5.
Like numerals of reference indicate like parts throughout the drawings.
In the drawings, 1 and 2 are the two halves of the body of my wall-plug, formed of suitable non conducting substance, preferably porcelain, cylindrical in form and of corresponding diameter at their meeting faces.
The part 1 is revoluble upon the part 2 by means of an axial pivotal connection. This consists of a screw 3, the head of which rests against the inner end of threaded socket-piece 4, let into the center of the outer end of the part 1, the threaded extremity of the screw 3 projecting into and engaging the threaded axial bore 5 of pin 6, passing through retaining bar or bridge 7 and having a head 8, which loosely engages the bar 7. In the meeting faces of parts 1 and 2 are opposing recesses 1 and 2, adording ample space for the reception and protection of the electrical connections hereinafter described. Surrounding the margin of the circular recess 2 is a metal ring 2". Surrounding the margin of the circular recess 1 is a like metal ring 1. When the parts 1 and 2 are engaged with each other by means of the screw 3 and pin 6, as above described, the rings l and 2 are in constant sliding contact with each other.
The threaded socket-piece 4, let into the center of the outer end of the part 1 when the device is in use, is screwed onto a threaded terminal in the wall-socket. The course of the current is now through the threaded socketpiece 4, screw 3, pin 5, bridge 7 to a bindingscrew 9 on the bridge, thence from the bindingpost 9 through a fuse 10 to a binding-screw 11 on the end of a short bar 12, secured to the inner side of the cavity 2, thence from a binding-screw 13 at the opposite end of the bar 12 out through aperture 14 in the endof part 2 on wire 15 to one of the lamp-terminals, thence through the lamp and back on wire 16 through a second aperture 17 in the end of part 2 to binding-screw 18 at one end of a short metal strip 19, the other end of which is connected to the ring 2 This ring being in contact with the ring 1", the current is now from the latter ring through a screwrod 20, the head of which engages a metal strip 21, connected with the ring 1, the opposite threaded end of the screw-rod being engaged with a concentric metal ring 22 in the outer end of the part 1. WVhen the device is in use, the ring 22 is in sliding contact with a corresponding ring on the wall or other fixture to which my device is connected.
My device is assembled as follows: The terminals 15 and 16 being slipped in through their apertures in part 2 and secured by their respective binding-screws, the pin 6 is slipped into place and the screw 3 is dropped into its socket and its threaded end is engaged with the threaded bore 5 of the pin 6. Now the part 1 may be rotated upon the part 2 without separation and may be screwed into connection with the wall or other fixture without twisting or entangling the Wires 15 and 16.
Having described my invention, what I claim, and desire to secure by Letters Patent,
In a device of the described character, a twopart body portion composed of suitable insulating material and having corresponding recesses in their meeting faces, detachable axially-disposed pivotal connections between the tacting metal rings in the meeting faces of the two parts of the body portion, a flexible conductorconnected with one of said rings, a flexible conductor connected with said pivotal connections, said two flexible conductors leadtwo parts of the body portion, a pair of con- 20
