l 5 opening lo the blades may be turned le prevented from accidental to shoulder so ment by laised portion lo and provided 'with an elongated slot23 ei;-

tending therethrough, and struck on the are 0l a circle. Vllhe base or oli'set 22 oli each blade is clamped down upon the cap proper by sn individual binding plete 2li, havingv sn to accommodate a screw 2S. The screw 26 clamps the binding plate 2d down on extension 22, end passes through opening` and slot 23 into the cap proper is inserted between the head of this screw 2o and plate'24 a` spring Washer 27. Each oiiset 22 hes upon its upper fece two raised portions 28 and .29, the function or" which will .herein later appear. Each plate 2e has on its lower face s depression 30 and is ro- 25 `vided with tivo shoulders 31 and 32, the

functions otl which will also later more fully appear. rEhe raised portion 30 performs no function. lt is merely s bulge in the metal due to the indented portion 30. Plates 2l eo are also provided with openings through `which pass binding screws 33 or securing the conducting wires to the device.

Each binding plate 2d hss one its edges struck on the arc of a circle, so as to fit 35 against and contorni to the contour 0I" the oi chamber 18, and each offset 22 has cte side its outer edge also struck on the arc circle for the same purpose.

llVith this arrangement, it will be seen that or adjusted vertically so that theii` elongated sides may be brought i to various relations with each other. When the blades are adjusted inthe parallel position shown in Fig. 2, they are displacement by 28 of eech blade engaging 30 of its respective binding the engagement raised portions with depression plate 24, and also by of raised portion 29 oi" each blade with 32 ot its respective binding' plate 24. When the blades are turned Jfrom the position shown in Fig. 2, so as to be in alii ement, as in Fig. 3, they are held in this plisition against accidental displace- 29 engaging depresl, end there y sion 30, .and also by raised portion 2dengagging shoulder Si.

ln Fig. d, the blades are shown edjusted to a position Where their extended sides are et right angles to each other. ln this cese, the lolsde 2l would be retained in position or locked, as described with reference to Fig. and the blade 20 would he retained or locked, as described with reference to Fig. 3. The means provided iorloclringg or retaining the blades in the adjusted-'pol tion-is ot course auxiliary to the clainpin, action ot plates 24, end l. do not wish vto be nn, stood as limiting my invention to such ngssiliary retaining; means. n

The spring Washers 2 permit cil?" the adjustment of the ble( es Withoutnseesserily loosening screws 26., lt should lie under.V stood, however, that these Washers may be` dispensed with if desiree. lt should also be understood that l do not liniit my invention to the particular adjustments ot the blades illustrated. i

lt will loe seen from the, foregoing description that a cap of this kind may be used with any of the arrangements ot sockets illustrated in Figs. 8 to ld, inclusive, or with receptacles having other errang-erneute of sockets.

ln Fig, l, l have indicated my cap as applied to a common -torni ol receptacle 34.

"Without limiting my invention to the specific embodiment thereof herein illustrated, what lclaim is l. A device ol' the class described, comprising; a cap, a Contact blade havinpg an offset or base provided `with an elongnted slotbe binding plate over seid offset, and :t screw passing through said binding" plete and said offset into said cap. l

2. A device of the class described, comprising e csphaving a vrecessed end provided with e curved Wall, u contact blade having an offset or hase-.curved to conform to the curvature ot said Walhsaid offset having an elongated slot therein, and having projections forming locking means, n bindingI plate over seid offset, and provided with shoulders to limit the angular movement of said oli'set, a screw passing tlirougli said bindingr plate und said offset into said cap, and a spring washer inserted between the head of said screw and said bindingplate.
