To all whom it may concern:
Be it known that -I, FRANK J. RcsssLL, a citizen of the United States of America, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Multiple Sockets for Incandescent Lamps,of which the following is a specification. I
' lamp sockets which are known as multiple sockets. or. cluster fixtures, and in which means are provided for receiving and holding a number of incandescent electric lamps, two, three or more, without-requiring the:
use of separate loose wires to each socket device. The object of: my invention is to provide an improved multiple socket of this character, especially one in which the body of the multiple socket is to be made of porcelain or other such insulating material, consti-i tuting what istermed commercially an all-porcelain socket, although my improvements are also applicable 0 .to cluster fixtures with metallic covers.
In the accompanying drawing Figure 1 isa vertical sectionthrough my preferred form of socket on the lines 11,' Figs. 2 and 3; Fig. 2 is'a face view of the socket with the lid removed; Fig. 3 is an inner face view of .the lid when removed from the body; Fig. 4 is a sec- 'tionahview, drawn to a smaller scale, of a part of the socket and showing a lamp in position.
The body A of the socket consists of a circular boxlike part of porcelain or the like with a central projection B, preferably tubular, and a series of semicircular radiating notches a in the wall of the box where the lamp bases are to be inserted. I have shown the multiple socket as arranged for six lamps, but oicourse, it
may be constructed for two, three, four or more, as de:
'35 sired.
The open lower end of the box A is closed by a lid 0, whichis also preferably of porcelain or the like and it has semi-circular notches c to match the notches a of the body and thus form circular openings of a size suitable 40 for the insertion of the lamp bases (Fig. 4). Opposite each of these openings, I provide a lamp holding device, consisting of a spiral spring wire D which is carried by the body part. For this purpose the spiral wire is formed with two ends d, d, which pass under an annular terminal plate E and are clamped to the bottom of the box bythis plate, the latter being secured in place by suitablescrewse set in from the back of the body (Fig. 1). One of the terminal wires brought into the a socket through the tubular center piece B and passed 5 through the notch b therein (Figs. 1 and 2) is connected electrically by binding screw 5 to the plate E and so to the. wire contacts Dfor the threaded ring terminals of the bases of the Edison lamps wheninserted.
v The contacts for the end or central lamp terminals are carried by the detachable lid 0, and they consist of a series of spring clips K, whose inner bent ends are clamped under an annular plate F secured to the inner face of the lid by screws f inserted from the outside (Fig. 1).- The outer free ends of these spring clips are preferably bent outwardly at their extreme outer ends as shown at the left of Fig. 1, and below this outer end I are madewith a concave-convex bend to slip over and My invention relates to' that class of incandescent embrace a shoulder s on the outside of the center piece gers K spring over and engage this shoulder s, which 6 5 then serves to hold the lid place, but so that it can be pulled off again, so long as the lamps are not screwed up. These spring clips are arranged radially opposite the'centers of the notches c in the lid so that when the latter is applied to make its notches match the notches a in the body, the ctlrved ends of the spring clips K will be directly back cf the centers of the lamp receiving spirals D, and when the lamps are screwed into place, the center contacts of the. lamps will bear against the curved ends of the clips K and clamp them to the retaining shoulder s'to lock the lid (Fig. 4) so that the lid cannot well be taken off, so long as a lamp is screwed up. One of these spring clips K, when the lid is in place, is arranged to lie over and contact with a metallic plate 7: (Figs. 1 and 2), which is bent over a part ofthe '80 shoulder s and is clamped in a notch b in 'the tubular center piece B, by aterminal plate 6 with'a binding screw 7 for the terminal wire.
I claim as my invention:
1. A multiple lamp socket, having a body part carrying 35 a. series of lamp-holding contacts with a detachable lid carrying a series of corresponding center contacts for the lamps.
2.'A multiple lamp socket, having a body part carrying a. series of lamp-holding contacts and two terminal plates for the wires with a detachable lid carrying a series of center contacts for the lamps, adapted to electrically conseries of center contacts foixthe lamp.
4. A multiple lamp socket, havlngn body'pa'rt carrying a series of lamp-holding contacts with a detachable 1i d. 1(
' having spring clips to engage a part of the body, the lamps when screwed in being adapted to bear against the clips to lo'ck'the lid to the body.
5. A multiple lamp socket, having a body partcarrylng a series of lamp-holding contacts and two terminal plates -with a detachable lid having spring clips to engage with a part of the body and adapted to make connection with one of the terminal plates, when the lid is in place and to form center contacts for the lamps.
6. A multiple lamp socket, havinga box-like-body part with a central shouldered projection, a .series of lampholding contacts carried by the body, a detachable lid carrying a series of spring clips to engage said shouldered projection and form center contacts for the lamps.
7. A multiple socket having a body part with a detachable lid, spring clips 'to hold the lid in place, and lamp-recehving parts, the lamps being adapted to bear against the clips to lock the lid when the lamps are screwed up.
10 notched forthe terminal wires, two terminal plates and a detachable lid with spring clips to inake electrical connection with one of 'the terminal plates, hold the lid in place and form end contacts'for the lamps.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses. 15
