CHAIN-GUIDE FOR ELECTRICAL PULL-SOCKETS.

Specification of Letters Patent.

Patented May 9, 1911.

Application 1ed February 15, 1911. Serial No. 608,825.

in chain guides for electrical pull sockets,V

and more particularly to a practical embodiment of the invention set forth in my other application tiled Jan. 5, 1911, and bearing Serial No. 601,026.

To` this end the invention has in view a novel means of mounting a divided chain guide of the type specified in the other application referred to, whereby the guide will normally perform all of the functions of properly guiding the chain of a pull switch, while at the same time entirely obviating thenecessity of threading the pull chain by permitting it to be entirely freed from confinement by the act of opening up the outside casing and removing the switch body.

Also, the inventionvcontemplates a oo nstruction wherein the separate sections of Ythe guide can be conveniently and readily reburnished, which is an operation usually carried out in preparing fixtures of this character for the market.

Vvlith these and other objects in view,

which will be readily apparent to those skilled in the art, the invention consists in the novel construction, combination, and arrangement of parts hereinafter' more fully described,illustrated and claimed.

Vvlhile susceptible to embodiment in various ways by use of different mechanical equivalents, the invention is Well exemplified by the single form thereof shown in the accompanying drawings, in which:

Figure l is an external View of an electrical pull socket embodying the present invention. Fig. 2 is a sectional view of the same. Fig. 3 is a view similar to Fig. :2 but illustrating the parts in separated relation to show the manner of opening the chain guide through the act of detaching the ca fromt. from the latter.

-Like references 4designate corresponding parts in the several figures of the drawings.

The improved chain guide broadly speaking, comprises guide supporting means, and a separable guide body consisting of two shclland removing the switch body g parts or sections whose line of separation is longitudinally of the body so that the latter may be said to be openable laterally to admit the laying in and removal of the pull phain at any portion of the length of the atter.

In the form of the invention shown in.l

the drawings, it is to be understood that the guide body may be of any suitable form or configuration, but is preferably of the usual horn or bell type and constructed of two parts or sections l and 2 of duplicate formation, with the line of separation longitudinally of the body and adapted to be brought into register to make the complete guide. According to the present invention, it is intended that one section of the guide, viz: the section l, be fitted to,

the removable switch bo'dy B of the pull socket, while the other duplicate and complcmental guide section 2 isfitted to, and carried by, the shell member 3 of the socket casing which includes the said vshell member and the usual cap 4. Any suitable means may be employed for securing the separate guide sections to their respective supportingelements. For instance, the guide section 1 may be fitted to, or formed with, a holding bracket or .arm 5 which is detachably held to the switch body B by a. fastening screw and carried by,`

G or equivalent means, while the other guide section 2 may be secured at its inner end to the body of the shell 3 by brazing, riveting, clenching, or equivalent fastening expedients well known to sheet metal workers.

The switch body B may be of any of the well known conventional forms and carries therewith a suitable, pull switch designated in its entirety b'y the reference letter S and including the usual pull chain 7 which is guided through the eye of the chain guide. l `urther,.the section l of the chain guide that is carried by the switch body B is adapted to move into and'out of a keeper slot 8 formed in the edge of the casing shell 3 in line and communication with the guide-section 2 that is carried by the said shell 3, so that when the two sections of the guide are in register, the guide section 1 is held firmly in position by the slot 8, besides acting itself as a holding means to prevent independent axial movement of the switch body B.

With the construction described, any fastoning connection may be provided between the shell and cap members of the casing and any adjustment o be cap on or ,about 'tbe shell 3 is not interfered Wlbb in the least. Furthermore, when the cap and shel :1re separated ae shown in Fig. 13, and, 'the switch. body lifted out, the chain guide becomes opened up and frees the chain.
