Sera] No. 696,5562
To alt whom t may concern Be it known that I, WILLIAM C. TnEGoN- i `new 'and useful Improvements in Electric- Lamp Sockets, of'which the followlng is a specification.
This invention relates to electric lamp sockets, and the invention consists in the construction and combination et parts sub-- stantially as shown and,describe d and particularly pointed out in the claims.
in the accompanying drawings, Figure l is a sectional elevation of the complete socket, land Fig. 2 is a sectional elevation of a portion of the socket at right angles to Fig. l and on the line of the key shaft. Fig. 3 is a plan view on a line corresponding to 3-,3, Fig. 2. Fig. e is a side elevation of the body portion of the coupling and the screw socket thereon for the lamp. Fig. 5 is a central sectional elevation of Fig. 4. Fig. 6 is a` plan of the switch plate shaped up for use and Fig. 7 is a plan of the blank plate. Fig. 8 is a cross section. of the upper of the porcelain or like disks shown in Fig. 4. Fig. 9 is a side elevation of the switch plate. Fig. 10 is a cross section of the lower of the two porcelain members seen in Fig. 4 on the line of the groove for the key shaft.y Fig. 11 is a perspective View of spring conductor adapted to be aiiixed to the body part shown in Fig. 10 and to close the circuit on the lamp, not shown, as seen in Fig. 2.
The complete socket as shown in these views comprises two porcelain or like nonconducting body members 2 and 3, referred to hereinafter as disks for convenience of description, and the member 2 isalso reterred to as the upper .disk and the member 3 as the lower disk for like reason. Both said disks necessarily have features of c0nstruction peculiar to the present invention and particularly to the adaptation of. the new and original form of switch plate It.
A,The said .plate is shown in Fig. 7 as struck "up in blank from a piece of suitable fiat plate, say copper or brass, and whichl is shaped originally .as seenin Figs. 6 and 9,
'is seen in Figs. l, 2 and-5.
while its relation to or in the 3Lporcelain disks v especting this plate, it is to be kespecially observed that it is a singlepiecc or part provided with a spring switch tongue a of cross shape struck up from the middle of the plate lengthwise and end portions b and c, relatively at the ends of said tongue 'which provide the two bearings for the key spindle or shaft. G while a lip d is provided at the end and side of the said plate providing a terminal for the socket, the said portions 7), c and (l being bent at right angles to the body of the plate, as clearly seen in Fig. 9. The shaft. hole or bearing c for key spindle G is shown as more or less enlarged as compared with the shai't in cross section for reasons presently to be seen and slight recesses are torni ed oppositely in said hole c to permit the small lugs lf: which are shown oppositcly on the spindle (5 to pass through the same and which lugs enter betweenythe lips 10 on the inside of saiditumbler and cause it to rotate with the shaft, the engagement of said parts however being comparatively loose within limits to allow freedom of movement between said parts. The said tumbler works 1n a recess toi/med partially in the two disks 2 and 3, and when the electric circuit is closed ithe tumbler is turned to make contact with the said switch tongue a at one end and with the spring contact or conducting member 12 at the other end, thus closing the circuit upon the lamp. Otherwise, or when the circuit is open, the tumbler lies cross-wise in its recess and out of electrical touch with at least one oi. said connections a. and 12 so as to break the circuit. The lamp makes contact with the contact spring 12 as above indicated while the current is closed on switch plate 4 through its lip or In 'fact the present construction is such as to renderla central screw unavailable as the plate Ltewith its tongue lies bodily across the space between the two disks, and both disks haveabout halt each of the required recess g formed thereon for the notation of tumbler 9 while'disk 2 has an inclined slot h running back from said recess to aord free play for the spring shank of said tongue, Fig. The comparatively loose support of the tuinbler on shaft 6 assures contact with the sociate parts a and 12 at all times regardless of the strength of the spring' in said parts. The tumbler shaft or spindle G has a washer n and is tip-set. more or less at its otherwise free end m to conne it in Working` position, and a'suitable depression or groove e is formed in the disk or bod.;T member 3 to accommodate said shaft next beneath the y plate 4 and which extends the bearing' there- 'oiz The sides of the plate l are also proff erably recessed to avoid Contact with screws l5 and 1G, and When the plate is in place between the disks, its main lood;7 portion borders the recesses in the disks and is clamped firmly all around, While lateral and end movement of the plate is prevented by the portions c and d. A single switch plate as thus constructed simplifies the socket ns a Whole and makes it more durable and less likely to get out of Working order. More over, it is distinguished from other dev/"ces known to me inithat the spring and the been ing;r lips for the key spindle ere projected in opposite directions 'and With the tumbler member adapted to pass through the plate to engage contact parts on opposite sides or" tbc plane of the plate.
` risino' a o11e-iiece switch late having :L
springtougue centrally therein and flips et its ends outside tbe ends of said tongue bent inward at right angles to said tongue and having spindle supporting openings. in coinl biuatinn with a spindle projected through said openings` a tumbler thereon adapted to Contact with said tongue and insulating members between Wliicli punte c eniped.
in testimony whereof l afiix my Signature
