CHAIN-GUIDE FOR PULL-SOCKETS.
To all whom it may concern:
Be it known that I, Cmnnxcn D. Pnvr'r, a citizen. of the United States, and a resident of Bridgeport, inthe countyof Fairfieldand State of Connecticut, have invented certain new and useful IIDPIUVQDIGIltS in Chain-Guides for Pull-Sockets, of which the following is a full, clear, and exact description, whereby any one skilled in the art may make and use the same.
The invention relates primarily to devices known in the art as pull sockets and is directed more particularly, as indicated by the title, to the guide for the chain or cord I of such sockets.
In fact, the invention more specifically relates, to a cord or chain guide, for pull sockets, of a special form and as an article of manufacture.
Heretofore, it has been common practice to use guides detachable from the body part of the socket and secured in various ways to a post or support between the insulating members of the socket body. The present invention contemplates a guide having not only the features of guiding the chain or cord, but also providing a substantial post or support between the insulating members, in a form, which is bodily removable. The advantage of removability is apparent, in as much as it is often necessary to re-finish the socketshell and the guide may therefore be removed and be re-finished to correspond to the shell.
The objects of the invention are to provide, in a single structure, a guide so formed from sheet metal as to provide a suitable guide and a substantial support between the insulating members of the socket.
A further object is to so form the device fromsheet metal that it will have ample material for securing it in place, smooth running surfaces for the pull cord or chain, and ample supporting means for the insulating members of the socket.
Referring to the drawings: Figure 1 is a view in elevation of a socket-shell and cap,
looking toward the bell of the chain guide.
Fig. 2 is a plan view of the parts shown in Fig. 1 with the cap removed. Fig. 3 illustrates a blank of metal from which the guide is formed. Fig. 4 indicates said blank after a stamping operation. Fig. 5 is a view showing the parts partially formed-up, the body part being of tubular form. Fig. 6 illustrates the parts subjected to a further Specification of Letters Patent. Patented Nov, 21, 1911,
Application filed December 23, 1910.
Serial No. 598,920,
operation with the bell part expanded or spun-up? Fig. 7 is a partial sectional View through the device illustrating the form of main support and screw-threaded boss for securing the same in place. Fig. 8 is a side viewof the socket-body illustrating the position of the supporting posts between the insulating members. i
In the drawings illustrating the invention the finished article is shown and is illus 'trated as being possibly formed in one or' more ways and, of course, by various operations, which operations are not absolutely material to the invention, but sufficiently illustrate steps by which the finished article may be produced. 7
Referring to the drawings, the numeral 1, denotes the shell and 2, the cap of a pull socket of the character referred to, provided with a chain guide 3. This chain guide 3, acts as a support between the two insulating members 4, 5, of the body of the socket,
'which is inclosed within the casing and cap 1, 2, and has an in-tu'rned foot-piece 6, and an in-turned locking piece 7, formed integrally with the tubular extension 8, and a bell-shaped mouth piece 9. Conducting supports 10, and 11, such as are ordinarily used in such type of sockets, cooperate with the chain guide support to give a substantial connection between the insulating elements 4, and 5. As the chain guide is wholly mounted in the insulation, it, of course, provides an insulated member through which the pull cord or chain 12, passes.
The operating mechanism of the switch of the socket forms no part of this invention and is'therefore not described herein.
The main feature of the invention consists in the chain guide struck up or drawn up from. sheet metal and consisting of a supporting element and a chain guide ele- 7, and is produced by utilizing a comparatively thin metal blank 13, which ispunched to a suitable form as illustrated at 14, in Fig. 4, and is thereupon struck-up through suitable operations into a form such as illustrated in Fig. 5, wherein there is a foot-piece 6, and'retaining-piece 7, in the form of in-' turned lugs extending from a main bodypart 15. These parts form the post or support between the insulating members 4, and 5. From the same blank of metal, there is also formed a tubular extension 16, which,
as illustrated in Fig. 6, may be spun-out to form the bell mouth 9. One of the lugs as, for instance, 7, is preferably cupped or drawn up as illustrated at 17, in Fig. 7, to form a screw-threaded socket of substantial length. The blank being of substantially thin metal, this cupping up of the boss 17,
gives a long threaded hole for a securingthe tubular guide being formed by folding the metal upon itself, and the angularly disposed securing pieces, 6, 7 by bending the metal that constitutes the post. The post and tubular guide are connected by a narrow neck 20, as clearly indicated in Figs. 4, 5 and 6. It will also be observed, particularly by reference to Figs. 5, 6 and 7, that the post is curved in line with the tubular guide 8, this preferably taking place at the time the guide is formed, thus stiffening the post and at the same time afiording ample space for the free movements of the pull cord or chain; and also that the attaching post extends laterally beyond the limits of the tubular guide and in the plane of its central axis, as clearly shown in Fig. 7. In either case, there is a chain guide member and a supporting member all formed from the same piece of metal by suitable mechanical operations, and the device, as a whole, serves not only as an ellicient chain guide, which is removable from or. attachable to any pull socket, but also serves as a supporting post or bracket between the insulating members of the socket.
Obviously, the exact method of formation of the article is immaterial and it might be made in various forms other than specifically shown herein, without departing from supporting post being curved in line with the tubular guide.
2. As an article of manufacture, an integral chain guide and supporting post for pull sockets formed from a flat sheet of metal, the chain guide being tubular in shape and the supporting post extending.
laterally beyond the" limits of the chain guide, inthe plane of its central axis, and being between said lateral extensions curved in line with the tubular uide. V
