GARNETT SN IDER, 0F BRUCES MINES, ONTARIO, CANADA.
.ELECTRIC-LAMP SOCKET.
Specification of Letters Patent.
Patented Jan. 6, 1920.
Application filed September 22, 1917'. Serial No. 192,785.
To all whom it may concern:
Be it known that I, GARNETT SNIDER, a subject of the King of England, residing at Bruces Mines, in the Province of Ontario, Dominion of Canada, have invented new and useful Improvements in Electric-Lamp Sockets, of which the following is a specification. V
This invention relates to an electric lamp socket, and one of the objects is to provide, means whereby a lamp may be secured to the socket more readily than when employing a socket of usual construction having a continuous shell, the walls of which are provided with a screw thread. 7
A further object is to provide a socket -which will positively engage the threaded block showing the device operated by the base of a lamp whensaid lamp is .merely forced or thrust into the socket and given a slight twist,-thereby avoiding the necessity of turning the lamp a number of times for causingthe full engagement of the contact elements.
A further object is to provide a socket in which one of the terminal members comprises a plurality of segmentalportions, the walls of which are formed with screw threads for engaging the threads of the lamp, these segmental members being con-' nected by a transversely extendin member retained in position by the .main tion of insulation, that is by the porcelain block, or the separate members constituting said block.
Fig. 2 is a view in elevation of the porcelain-block and the elements carried thereby for engaging the lamp.
Fig. 3 is a bottom plan view. Fig, 4: is a perspective view of the lamp retainlng members.
Fig. 5'is a transverse section through the spindle for making contact,
The main casing of the socket is designated is shown at 12, the casing and cap bein provided, with an inner lining of insu ating ody por- .an abrupt incline.
A still further object is to provide a socket 1 celain insulation includes a plurality of members 14; and 15, and the usual key 16 is mounted on a spindle 17 which latter includes an OIISGtQpOItlOIl 18 cooperating with the U-shaped resilient device 20 which is slidable longitudinally with reference to the spindle in view of its engagement by the OH- set portion and causes the movement of said U-shaped member into engagement with the contact member 21 carried by a device of special construction mounted Ion the porcelain block and designed to be directly engaged by the threaded base'of the lamp. When the member 20 is in engagement with the contact member 21 it is also in engage- 'ment with terminal 22, completing one side of .the circuit. The other terminal is designated 24 and extends to the central portion of the socket as shown. In Fig. 5 element 20 is shown as having one" prong (which is normally the upp r prong) bifurcated, for engaging eleinents 21 and 22. The other end engages an angle formed by ofiset 18, when the switch is open. Upon turning the spindle 17 through 180 degrees, the opposite side of the ofi'set portion will be en aged, and this side'is reversely inclined, aier a onehalf revolution of the spindle, so that the tendency of the spring in expanding is to move toward the left in Fig. 1, and into position to close the switch. The split end of the spring is then moving downwardly along The offset portion is somewhat flattened. v
The shell or socket proper which directly engages the threaded portion of the lamp base comprises a plurality of members 25 and 26 of segmental form, these members having walls formed with screw threadsfor engaging the lamp base, and being connect extending member 28 which is carried by the body portion of insulation comprising the sections 1 1' and 15. Each section speclfied includes an upwardly extending member 29 having an' undercut portion 30, the
oppositely located sections forming by reason of the portions indicated, a transversely extending channel accommodating the connecting member 2'80f the shell. This member -28 is of material sufliciently heavy 'to provide the necessary degree of resiliency for the segmental members 25 and 26, causing them to firmly engage the lamp base.
b6 material as shown at 13 and. 14, The per Th e elements 25 and 26 are broader than the 119 and comprising a plurality of segmental members formed with threads, a trans-- member 28 but are not of sufiicient extent to cause the edges thereof to meet, a space being provided'at 30 and at 31 as shown.
The segmental members and 26 may be outwardly flared to a slight extent as shown 1. In a device of the class described, a
casing, a body of insulation inclosed thereby and including a plurality of sections, ashell forengaging the threaded base of the lamp versely extending member connecting said segmental members, said sections of the body portion being provided with channeled portions-oppositely located for receiving the transversely extending portion of the shell. I 2. In a device of the class described, a
tending from one end'there'of'and spaced from the corresponding member of the adjacent section when the sections are secured together, each of said members having an undercut portion, said portions formin together a channel extending transverse y of theabody portion and in the direction of the line of division -between the sections, a shell for engaging the base-of a lamp and comprising a plurality of segmental members the walls of which are provided with threads, and a transversely extending member of resilient material connecting the segmental portions and causing the latter to firmly engage the base of the lamp thrust longitudi nally between said segmental portions, said transverse inember being located within the channel. v
In testimony whereof I aflix my signature.
