These sections meet in spring. The washer 26 is non-rotatably cona plane parallel to and intersecting the longinectedto the end of the shaft 19. For the tudinal axis of the connecter and are held topurpose of rotating the insulating block 20 with its contact members 21, a flexible operator or pull chain 28 is connected to an extension 29 formed on the plate 22. This pull chain 28 passes outwardly of the chamber 17 through a chain guide or bell 29a which is formed in the engaging faces of the sections A and B. 4

The exterior surfaces of the portions of the body forming the boss 13 are formed with a screw thread for meshing with the interior thread formed on the screw-ring C. This ring encircles the portions of the body forming the boss 13 and assists in retaining the 15 To secure the ring in place, that is, against unscrewing movement, the outer flange there- 4 of is vbent down as shown at 0' in Fig. 4 into the notches 13a. v

The screw shell 31 is adapted. to be mounted inthe socket portion 14 of the assembled body, as best illustrated in Figs. 3 and 4. For the purpose of mounting this shell 31 by the act of assembling the body sections A and B, the latter are provided with lugs 32 which preferably are diametrically opposed, and the shell is provided with registering apertures 33 fOrreceiving the lugs.

' ,The side outlet 15, as stated heretofore, is 'formed by suitably shaped projections carried by the body sections A and B. Openings 34 are formed in the end face of this side outlet 15 for receiving the blades of a plug \35 of the type illustrated in dotted lines in Fig. 11 The outlet 15 is provided with the plug terminal receiving recesses 36, which register with the openings 34, and the inside face or wall of the section B is. provided with the ribs 36a and 366 whose functions will presently appear.

An opening 37 is formed partly in each of the end faces of the sections A and B which occur at the extremity of the boss 13. This opening accommodates-the ribbon-like conductor 38 which is bent over at itsouter end 38a to form a contact. The inner end of the conductor is anchored at 39 to the thickened wall portion 18 and is connected by the anchoring means to the stationary-contact 40 which forms apart of the pull chain switch mechanism. A second contact 41 isconnected to anchoring means-42 which likewise is carried by the-thickened wall'portion 18. This anchoring means 42 connects to the switch contact 41 a'center contact 43 located within the screw shell 31. The male ring 0 electrically contacts with a conductor spring 44 which extends lengthwise through the chambero17 and around the rib 36a to be connected by a rivet or the'like 45 to the screw shell 31. The end of the conductor 44, beyond the rivet 45, is provided with a return bend 46 to form a plug terminal contact 47 arranged within the recess 36 in line with one of p, the openings 34. Another conductor spring 48 has one end passing through the portions in their proper assembled position.

opening 37 and is bent at an angle to form a contact 48a similar to the contact 38a. This conductor 48 also extends through the chamber 17 andits intermediate part is clamped against the wall 366 while the other end is .doubled upon itself to provide another plug terminal finger disposed in the other of the recesses 36. 'The sections A and B, after the switch mechanism and the various conductors and shells are arranged in their proper places, may be further connected by an eyelet E passing through apertured ears 15a formed in the manner illustrated in Figs. 1 to 3, inclusive. I

It now will be seen that-the connecter may be threaded into an ordinary light socket by means of the boss 13 and its encircling ring C. The circuit for the female shell 31 will be controlled by the pull chain switch mechanism illustrated. The contacts 47 and 49 registering with the openings 34 in the side outlet will be free from all control by the said switch mechanism. The connecter will permit of a bulb being threaded into the shell 31 and controlled by the pull chain switch 99 mechanism while a lamp cord, or the like, may be connected to the side outlet and be provided with a closed circuit irrespective of the condition of the pullchainswitch mechanism. 7 Figure 5 illustrates a slightly modified form'of connecter in which the boss 13 is dispeI lsed with and a cap or equivalent annular orring like member 50 is threadedly connected with the separate portions forming the 100 body 10a. This'cap 50 is provided with an opening 51 for accommodating the wires 52 which are connected by screws 53 to the conductors 38, 44 and 48 of the mechanism disclosed in Figs. 3 and 4.

The pull chain switch mechanism in the structure shown in Figure 5 may be the same as illustrated in Figs. 3 and 4. A female screw shell and a side outlet similar to those illustrated'in Figs. 3 and 4 also may beprolar member or ring which may be threaded to engage both sections, while a single fastening locks both members near the opposite end against slippage or separation. In -assembling the device the body section B may have the pull chain switch mechanism assembled thereonas well as the center plug contact 43 of the screw shell 31, together with the contact 3838a for the plug end of the device.

1 The spring conductor member 44 which is carried by the screw shell contact 31 may then 13) be placed in position so that the end 44a lies in recess 44?) while the bent terminal finger 47 for one of the blades of the push-plug, lies in one of the recesses 36, and the screw shell itself engages over one of the lugs 32. The other spring conductor member 48 may then be fitted into the space between the rib 36b and the body so that the end 48a thereof forms a part of the center contact for the plug end of the device while the portion 49 lying within the other of the recesses 36 constitutes the second push-plug terminal. When the various parts are assembled, the cover section A maybe placed in position and the screw threaded ring C may be threaded onto the threaded end portions of the sections A and B to hold them together and at the same time make an electrical connection between the ring C and the end 44a of the spring contact member 44. When the rivet, eyelet or equivalent fastening E is placed through the aperture ears 15a, the entire assembly will be held in place to complete the device. The lugs 32 which enter the openings 33 in the screw shell contact not only hold that member in place but also prevent its rotation during the screwing in and out of the lamp bulb, and take the strain ofi of the connection between the screw shell and the conductor to which it is attached.

WVithout further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
