Description

UNITED sTATEs PATENT oEEioE.
CHARLES R. HABE, OF HARTFORD, CONNECTICUT, ASSIGNOR T0 THE ARROW ELEC- TRIO COMPANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT.
PULL-SOCKET.
Specication of Letters Patent.
Patented Apr. 21, 1914;.
Application led December 18, 1913. Serial No. 807,466.
.ford and State of Connecticut, have invented a certain new and Improved Pull-Socket, of which the following is a specification.
My invention relates to pull sockets and particularly to the lining therefor, the object of my invention being to improve the usual insulating lining in the feature hereinafter described.
In the accompanying drawing, Figure 1 is a dropped perspective of a pull socket in the lining of which myinvention is embodied in one form; Fig. 2 is a side elevation ot' thel socket, partially broken away; and Fig. 3 is a vertical section through the lining alone.
The pull socket here shown, comprises cap 10, shell 11 and socket body 12 carrying screw shell terminal 13 and switch' operating pull chain 14; The latter emerges from the casing through a chain bell 15 the base 16 of which is here shown mounted on the socket body, but it is to be understood that the in vention is equally applicable to pull lsockets in which the chain bell is mounted on the shell 11 as has been common practice until recently. An insulating lining 17 is generally provided within the shell to insulate the terminal 13 therefrom and to prevent accidental cont act between the shell and any of the electrically alive parts on the socket body. This lining is provided with a slot 18' which embraces the base of the chain bell 15.
ln pull sockets of the construction illustrated, the slot 18 engages each side -ot the base 16 of the chain bell 15. As a result ot' this arrangement it not infrequently hap-` happens that the return of the chain under the influence of the switch spring, 1s prevented through the engagement of the edge of the lining by a ball of the chain. To obviate this difficulty I have provided a clearance for the chain by bumping the lining outward'adjacent the slot 18 at the point 19 l which registers with the chain in the assembled position of the parts. While this clearance may be effected in various other ways, this particular method has the advantage of maintaining the insulation as perfect as heretofore. At thc same time it adds to the security of the latching engagement between the shell and cap, since it presses outward against the portion oi the shell in which the latching elements 20 are arranged and thus aids the spring of the metal in maintaining the latching engagement tight.
It is obvious that the outward bumping oi? the lining at 19 maintains the edge of the lining at this point out of position to engage or obstruct the movement of the chain as itenters or returns 'through the bell.
' I claim as my invention 1. In a pull socket` a casing, a socket body within the same, a chain bell having a base mounted on said body, an insulating lining surrounding said socket body and having a. slot embracing said base of the chain hell, said lining being bumped outward adja ent said slot to afford a clearance for the pull chain. substantially as described.
2. ln a pull socket, a casing, a socket body wit-hin the same, a pull chain carried by the latter, a lining interposed between said socket body and casing, 4aid"lining having a slot to permit the passage ot said chain therethrough. and being outwardly bumped adjacent said slot to attord a clearanf'c for the chain. substantially as described.
In testimony whereof l have sign :d my name to this specification, in the presence of two sul'iscribing witnesses.
