Description
n 1955 P. A. ALESS! PANEL LIGHT socmz'r Filed March 25, 1953 iNVENTQR PATRICK A. ALESS ATTORNE United States Patent 0 PANEL LIGHT SOCKET Patrick A. Alessi, Needham, Mass, assiguor to Sylvauia Electric Products Inc., a corporation of Massachusetts Application March 23, 1953, Serial No. 343,949
5 Claims. (Cl. 339-126) provide for proper mounting of the sockets on the panel and for proper electrical contact with the bulb inserted into the socket. It is to satisfy these requirements that the novel socket herein described and illustrated in the accompa it ,in drawing has been contrived.
The subject matter herein is related to the socket disclosed in the application of L. R. Wanner, Serial No. 344,035, filed concurrently herewith.
in the drawings:
Fig. l is an exploded view of the socket and bulb assembly utilized therewith, parts of the socket being shown in section.
Fig. 2 is a sectional view through the socket, the bulb assembly being shown in place.
Referring to the drawings more in detail, it will be noted the socket is comprised of four parts, namely, a central hollow cylindrical metallic contact member or collet 19, an insulating sleeve or bushing 12, a metallic shell 14 and a screw threaded metallic contact plate 16.
The collet 16 has an inner wall flaring outwardly to meet the outer cylindrical wall, thus forming a thin edge portion l3 adapted to be rolled outwardly over electrically conductive panel member 20 to which the socket may be readily attached. The other end of the collet has a circular outwardly turned flange 22 cooperating with a complementary inwardly turned flange portion 24 on the bushing 12. The collet 10 therefore serves to securely mount the socket on the panel with a face of the bushing nst the rear face of the panel. The bushing is further provided with outwardly turned flange 26, there being a sloping wall 28 connecting a free edge of the flange with the cylindrical portion of the insulating bushing. The metallic shell is an annular member with a cylindrical wall 30 surrounding the bushing and a planar centrally perforated end 32 engaging a plane face of the bushing. The free edge of the circular wall is spun over the flange 26 as indicated at 34. The plate 16 is a stamping provided with an ear perforated at 36 and having an internally threaded boss 38 extending into the central opening of the end of the shell but terminating short of the flange portion 22 of the collet. The internal diameter of the boss is slightly greater than that of the collet 10 to allow a bulb to be screwed into the socket, with one terminal of the bulb engaged with the threaded boss and another terminal seated against the flange 22 of the collet. The plate 16 is secured to the shell in any suitable means such as by soldering or brazing. The type of bulb employed is illustrated at L.
For bulb energization, terminal wires would be secured to the shell directly or more conveniently to the eye 36 of the plate and to the conductive panel 20.
Although I have described a specific form of my inven- 2 tion, it is obvious that many modifications thereof may be made without departing from the spirit of my invention and what is claimed herein.
Having thus described my invention, what i claim is:
l. A socket comprising an insulating bushing having an inwardly turned flange at one end and an outwardly turned flange at the other end, a metallic contact member having a wall portion extending outwardly of the inwardly turned flange portion of the bushing and an outwardly turned flange engaging the inwardly turned flange of the bushing, a metallic shell member having a wall surrounding the outwardly turned flange or the bushing and an inturned portion over-lapping the outwardly turned flange and also having an annular flat portion engaging the outturned bushing flange on the side opposite to the overlapped portion thereof, said metallic shell member having means to threadedly engage a bulb with one terminal of the bulb engaging the threaded portion and the other terminal the outwardly turned flange of the metallic contact member.
2. A socket comprising an insulating bushing having an inwardly turned flange at one end and an outwardly turned flange at the other end, a metallic contact memher having a wall portion extending outwardly of the inwardly turned flange portion of the bushing and an outwardly turned flange engaging the inwardly turned flange of the bushing, a metallic shell member having a wall surrounding the outwardly turned flange of the bushing and an inturned portion overlapping the outwardly turned flange and also having an annular flat portion engaging the outturned bushing flange on the side opposite to the overlapped portion thereof, said metallic shell member having a plate member aflixed thereto having an internally threaded boss to threadedly engage a bulb with one terminal of the bulb engaging the threaded boss and the other terminal the outwardly turned flange of the metallic contact member.
3. A socket comprising an insulating bushing having an inwardly turned flange at one end and an outwardly turned flange at the other end, a metallic contact member having a wall portion extending outwardly of the inwardly turned flange portion of the bushing and an outwardly turned flange engaging the inwardly turned flange of the bushing, said extending wall portion being tapered in thickness so as to be thin at its free edge to facilitate spinning the wall portion over the face of a socket supporting panel, a metallic shell member having a wall surrounding the outwardly turned flange of the bushing and an inturned portion overlapping the outwardly turned flange and also having an annular flat portion engaging the outturned bushing flange on the side opposite to the overlapped portion thereof, said metallic shell member having a plate member aflixed thereto having an internally threaded boss to threadedly engage a bulb with one terminal of the bulb engaging the threaded boss and the other terminal the outwardly turned flange of the metallic contact member.
4. A socket comprising an insulating bushing having a central opening with inturned flange, a metallic electrical contact member therein having an outwardly turned flange bearing on said inturned flange, said metallic member having a hollow neck portion with unobstructed access thereto with said neck portion extending a distance beyond an exterior face of the bushing, and a second contact means on said bushing parallel to said exterior face, said second contact means being spaced from said metallic member, said second contact means further being provided with a threaded opening in registration with the unobstructed hollow neck portion whereby a lamp having a glass bulb may be threaded into said second contact means with the glass portion lying within the hollow neck portion and a contact member of the lamp engaging the metallic member, and said second contact means having provision whereby a conductor may be attached thereto.
5. A socket and panel organization comprising an insulating bushing having a central opening with inturned flange, a metallic electrical contact member therein having an outwardly turned flange bearing on said inturned flange, said metallic member having a hollow neck portion with unobstructed access thereto extending a distance beyond an exterior face of the bushing, a panel, the end of said neck portion being spread outwardly over a face of the panel with the bushing held tightly against the opposite face of the panel, and a second contact means on said bushing parallel to said exterior face, said second contact means being spaced from said metallic member, said second contact means further being provided with a threaded opening in registration with the hollow neck portion whereby a lamp having a glass bulb may be threaded into said second contact means with the glass portion lying within the hollow neck portion and a contact member of the lamp engaging the metallic member, and said second contact means having provision whereby a conductor may be attached thereto.
