fipecification of Letters Patent.
Patented April 10, 1906.
Application filed July 14, 1905, Serial No. 269.636.
-Be it known that I, HARVEY'HUBBELL, a citizen of the United States, residing at Bridgeport, county of Fairficld, State of Connecticut, have invented a new and useful Chain-Guide for Pull-Sockets, of which the following is a specification.
This invention has for its obj eat to provide a chain-guide for pull-sockets which shall be so constructed that it may be attached centrally andradially to the socket instead of at one side and tangential thereto, thus greatly improving the contour and general appearance of the socket, and which shall provide for the" rise and fall of the segment in use, giving at all times a smooth and rounded runway for the chain. This result I accomplish by making the guide bell-shaped at its inner end and providing a shoulder which rests against the outer side of the shell of the socket and a hub which passes through the shell and whose edge is then turned outward and closed down upon the inner side of the shell.
Afurther object of the invention is to pro vide a two-part chain-guide the top or outer part of which shall be made in varying lengths to adapt it to pass through a husk, so called, or other ornamental fixture used in connection with an incandescent lamp and engage a base attached to the socket.
With these and other objects in view the invention consists in the special construction of chain-guides which I will now describe and then specifically point out in the claims hereunto appended.
In the accompanying drawings, forming a part of this specification, in which reference characters are used to indicate the several parts, Figure 1 is an elevation ol an incandescent lamp and a husk, illustrating the use in connection therewith of my novel chainguide; Fig. 2 a horizontal section on the line 2 2 in Fig. 1 looking up; Fig. 3, a similar section illustrating a form of my novel chainguide made in a single piece, and Fig. 4 is an enlarged sectional view of a two-part .guide detached.
10 denotes an incandescent laii'ip;'I1, the socket,- 12, the segment; 13, the chain; 1 1, a husk, and A mynovel chain-guide as a whole. As the construction of the socket mechanism has nothing to do with. my present invention,
It is sufiicient for the purposes. of this specification. to
say, that the chaln passesthrough the guide and the inner end of the chain passes around the periphery of the segment and 1s attached thereto at the end opposite to the inner end upon; the chain might be as direct as possible,,
it hasb'een customary to place the guide at one side of the shell and substantially tangential thereto. This construction is objectionable for several reasons" notably, that the general configuration of the shell is marred thereby, that it is more expensive to manufacture, and that it is not convenient to use the guide in connection with a husk or other ornamental fixture surrounding, and concealing the socket. These objections I wholly overcome and am enabled-to attach the guide centrally to the socket and radially thereto and make the chain run freely therein by n'laking. the inner end of the guide bellshaped, as at 15. This enables me to carry the chain around farther 011 the segment, which is a great improvement in practice and provides a smooth. rounded runway for the chain in any position of the segment, all angles for the chain to pass over being avoid ed and a smooth rounded surface being providcd, over which the chain will ass freely.
In Figs. 1, 2, and 4 I have il ustrated a form of the invention in which theguide is made in two parts in order that it may be used in connection with a husk or other ornamental fixture. ln. this form 16 denotes the base of the guide, which is provided with a shoulder 17, adapted to bear against the outer side of the shell, and a hub 18, which passes through a hole in the shell and is .opened outward and closed down upon the inner side of the shell, as clearly shown in Figs. 2 and 3. The outer end ofthe base is provided with an internal screw-thread terminating in a shoulder 19. 2O denotes the top or outer part of the guide, which is preferably bell-shaped at its outer end, as at 21.
At the inner end of the top is an external screw-thread terminating in a a shoulder 22. This thread is adapted to engage theinternal thread in the base, the end of the top en aging the shoulder in the base and the shoulder on the top engaging the outer end of the base, so as to leave the uide as a whole as per fectly finished both mternally and externally as if made in a single iece. The tops are made of difierent lengt s to adapt them for use with husks and various other ornamental.
fixtures. When used inconnection with a husk, the inner end of the top is passed through hole in one of the leaves of the husk and engages the base which lies within the husk. By detachin the top the socket may be removed from t e husk and a new one .the same manner as the hub is attached in the other form.
Having thus'described claim k 1. A chain-guide for null-sockets comprismy invention, I
ing a base having a shoulder ada ted to engage the outer side of a'socketell, a hub adapted to be passed through a socket-shell 2 5 and closed down upon the inner side thereof and a screw-thread at its outer end and a top having a corresponding screw thread by which it inay be attached to t e base after the latter is attached to a socke shell.- d
2. The combination with a pull-socket shell and a husk, of a chain- 'de comprising a base having a shouldera a tedjtoengage the outer side of the socket-shell anda hub adapted to be passed through the shell and 35 I closed down upon the inner side thereofan d a top adapted to be passed through the husk and engage the base. V In testimony whereof I afiix my signature in presence" oftwo witnesses.
