UNITED STATES PATENT OFFICE..
JOHN CUTHBERT, OF CHICAGO, ILLINOIS, A SSIG-NOR TO ECONOMY FUSE .AND MANU- FACTURING COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF NEW' YORK.
ELECTRIC FIXTURE.
Application filed May 21, 1920. Serial No. 383,083.
To all whom t may concer/n Be it known that I, JOHN GUTHBERT, a citizen ofthe United States, residing at Chicago, in the county of Cook and State o-f Illinois, have invented certain new and useful Improvements in Electric Fixtures, of which the following is a specification.
This invention relates to electric fixtures. More particularly it relates to fixtures including electric sockets to which may be attached electric lamps, plug connectors, etc.
It is sometimes necessary to provide electric fixtures wherein lamp sockets and the like are secured to or incorporated with pipe fittings7 bracket-plates, canopies, shades, re flectors, etc. It has been the usual practice to secure the sockets to the pipes, canopies, shades, reflectors and the like, by means of set screws, screw or ring clamps, etc. The canopies, shades, reflectors, etc., sometimes have been threaded to receive a threaded projection on the socket. Such expediente often prove unsatisfactory. Set screws are not always permanent and reliable. Whe-re the socket and canopy7 shade, refiector, or the like, are complementarily threaded7 it may be necessary to rotate the socket in order to secure it in place. This is objectionable as the conductors, when fastened to the socket terminals, are twisted and may be broken or loosened from the terminals.
An object of the present invention is to provide an improved electric fixture.
Another Objectis to provide for the ready and easy securing of electric sockets to pipe iittings, canopies, shades, reflectors, etc.
Another object is to provide a simple and inexpensive fastener for an electric socket.
Other objects and advantages will appear from the specification and claims.
Embfodiments of the-invention are shown in the accompanying drawing.
In the drawing Fig. 1 is a perspective of a socket and canopy.
Fig. 2 is ia longitudinal section of the structure shown in Fig. 1.
Fig. 3 is a perspective of a socket combined with a canopy and pipe tting.
Fig. 4 is a longitudinal section of the structure shown in Fig. 3, Iand Fig. 5, is a perspective of `a clamping sleeve.
Figs. 1 and 2 will first be described.
The fixture shown comprises an electric socket 10 and a support in the form of a canopy 11. The socket may -be of `any desired fonin and of either the key or keyless type. Examples of sockets which may be satisfactorily used are,` illustrated inl my copending `application Serial No. 383,082, filed May 21, 1920, and application Serial No. 383,085, filed May 21, 1920. It has: an exteriorly threaded projection 12 provided with an axial opening thru which conductors may pass into the interior of the socket.
Canopy 11 is represented as of inverted bell shape. It may be adapted, in any desired manner, to be held against a wall or other support. The canopy has an opening through its center for the reception of socket projection 12. This opening need not be threaded.
An interior-ly threaded nipple 13 is provided to clamp the socket and canopy into a unitary structure. Nipple 13 has an opening therethrough for the passage of conductors and its threads are adapted to register with the threads on socket projection 12.
To assemble the structure, projection 12 of the socket is inserted through the opening of the canopy. Then nipple 13 is screwed down upon the projection, binding the edges of the canopy opening between the lower edge of the nipple and the rear shoulder of the socket.
The conductors may first be connected to the socket terminals. There is no necessity for thereafter twisting the conductors as the socket is inserted in the canopy by a straight axial movement, and the clamping of the parts together, by the tightening of the nipple against the rear of the canopy, does not twist the conductors.
The socket may be placed Aon the concave side of the support and the nipple clamped down against the convex side thereof. This arrangement would be used where the support is a shade, reiector or rosette. The action of the elements are precisely the same as that previously described.
Figs. 3 and 4l show `a socket and a support in the form of a canopy, clamped to a pipe tting to comprise7 in effect, a unitary structure.
exteriorly threaded projection 16, through which rthe conductors pass into the interior. Support 17 in the form of a canopy has an opening therein for receiving socket projection 16. The center of canopy 17, about its opening, is formed into a small rosette or nest for fitting the rear of the socket.
Socket and canopy 17 arefitted and secured to the end of a pipe 18 through which the conductors are led to the socket. A small flexible sleeve 19 is fitted over the end ot pipe 18. Sleeve 19 is composed `of suitable material such as soft spring steel. It may be slotted as shown to make it more iexible. Each end of sleeve 19 is chambered to provide wedging surfaces 20. An
interiorlj7 threaded nipple 21, similar to smaller end being toward the rear thatpreviously described, is adapted to be threaded upon socket projection 16 and clamp the socket, canopy and pipe 18 together, The bore of nipple 21 is tapered, the as clearly sho-wn in Fig. 4L. As nipple 21 is threaded upon projection 16, the tapered inner wall of the nipple bore engages the rear wedging surface 2O of kslee-ve 19. The sleeve is forced forward toward the socket so that its forward wedging surface 20 engages the upper edge of projection 16. The sleeve is also Vcompressed to tightly clamp pipe 18. When the nipple is threaded so that it clamps the canopy tightly against the Arear of the socket, sleeve 16, because of the wedging laction or its forward and rear wedging surfaces against the edge of projection 16 and the interior Wall of :nipple 21, respectively, tightly grips the pipe. The socket, canopy and pipe are thus firmly clamped together.
The parts may @be readily separated .by loosening and removing the nipple. Since the .part-s are assembled by merely uniting `them by -straight axial move-ment, there `is no necessity for turning the socket and the pipe and the conductors are saved from twisting.
The supports may take various forms and be used for various purposes. The Word support is to be taken to mean base- -plate, canopy, shade, yreflector and similar iittings .adaptedy for use ywith electric sockets.
