Improvement in. Lamp-Sockets, of which the followil'lg a specification.-
My invention relates to electric-lamp sockct-s, particularlysuch as are in tendedforuse 1n connection with signs.
It is illustrated in the accompanying drawing,"Wl1ereln- I Figure l is'a plan View cl a portion of a slgmboard with one socket in view. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is View of the bottom of the socket.
Like parts are indicated by the same letter in all the A is the sign-board, B the base of the socket, and C the socket proper. The base has the usual terminals 15' B with the securing and contacting rods B B B B and B are adapted to hold in position the internally and externally screw threaded thin. metal piece C and to make connection etWeen the same and the terminal B. The bolt B holds in position the i1 ation-(lisk if at the bOll" 1 tomol the socl -piece Cand also furnishes t an exposed contact end B to engage the lamp when. the latter is screwed into position,
as hereinafter plained. There 1s a deep aiinular recess .in. the forward end of the base, indicated at l, to receive an.,lnwardly-projecting annular flange C on. the socket C. The parts l5 and C are opposed to each other by [lot shoulde or surfaces and When in position are separated, so to give rem. board or shectpiece A. 'lhe socket C is preferably corrugated. on its outer surface, so that it can easily be screwed up ltly against the plate A to bring all the parts into position. It is also internally screw threaded, so that it is screwed down upon and so as to inclose the socket-piece l The part" 9.11 ol course be varied and are to be taken in a sense shown diagrammatexpose the lamp to view as a conspicuous ob ject-that is, particularly Where lamps are utllir: to form, for example, lettered s1gnsit is hichly desirable to have the least possiblle other words, my socket for the purposes for which it is- 1: fl may be considered as a socket, part- .)1 which is exposed and part concealed. The makin of such signs has become a very considers le industry and'the p gblic has become ver critical and insists upon the least possib e exposure of the socket, so that the lamp itselfmayattract all the attention of the observer. At the same time the underwritersor others who are clothed with the authority to determine what kind of apparatus should be used are insisting upon heavier and more solid sockets. This requirement in the sockets as heretofore used resulted in a very heavy socket-piece, and since under previous structures the socket-piece has been adapted to lie Wholly on the socket side of the supporting board or sheet the result was a very heavy and unsatisfactory socket, and when a series of such sockets were arranged in a sign-board the re eultWashighlyunsatisfactory. To overcome these difilculties is the object of my inven tion. Broadly speaking, I accomplish that object by putting my socket portion on both sides of the board or projecting a portion of it through the board or sheet to a consider able extent or great depth. This gives me a heavy socket-piece, but a small portion of which necessarily lies on the exposed side of the supporting-plate. I have shown this socket as lying about half of it on. the ex posed side of the plate. It is obvious that. by this invention I have divided the underwriters requirements and dealt with each separately. In other words, t satisfy their requirement that the socket-piece be heavy I l have extended and developed it on the back side of the plate, While to satisfy their reuircment that there shall be an appreciable distance between the sheet and the metal piece 0, I am permitted to use a socket C with the smallest permissible outer projcction. The proportions of the parts as shown may be greatly varied.
