OUTLET.

Application fled m 1, 1925. Serial No. mass.

My invention relates to certain improvements in electric outlets, hieh are used especially in house lighting;

One object of the invention is to design the terminal plates within the outlet casing so that two types of plugs can be used.

A further object of the invention is to form theterminal plates in such a manner that the sheet metal, from which the terminal plates are made, is bent across the grain of the metal, so that the metal retains its elasticity and does not break or crack at the bend.

Fig. 10 is a transverse sectional view'on the line l0-10, Fig. 9; I

Fig. 11 is a perspective view of one of the terminalsused in the single outlet; and

Figs. 12 and 13 are views of the blanks from which the terminal plates are formed.

The bod Figs. 1 an 4 is made of a non-conducting material, such as hard rubber, and has two sets of =T-shaped openings which are inserted the blades of the plugs, which are shown in Figs. 2 and 3.

There are two types of plugs in general use. In one type of plug 3, Fig. 2, the contact blades 4; are arranged side by side. In the other'type of plug 3, Fig. 3, the contact blades 4 are arranged edge to edge.

The T-slots in the body 1 of the outlet are so arranged that they accommodate the blades of either plug. The body 1 of the outlet is made hollow to receive the terminal plate 5, Figs. 6 and 7., Each terminal plate has two projecting terminals 6, with 1 of the outlet illustrated in,

scribed, 1t'w1ll-benoted that the terminal 2 therein, Einwhich the contact blades of the plugs engage, and a centralbinding post 7 to which the wire is attached.

The terminals 6 are made by bending the blank shownin Fig. 12 to the formeshown in Fig. 6, transversely to'the grain of the metal. The member 8 of each terminal 6 is bent upwards, then downwards to form a spring tongue 9. The member 10 is bent upwards against the tongue 9 and is so poenlarged at the bend to form a tapered open-V ing for the blades I In Figs. 8, 9 and 10,-a single outlet is shown, which has two T-slots. In this construction, the terminal plates" 58- are short andare made Ins-illustrated in Fig. 11. The terminal 6 is bent in the same manner as the the end of the plate. 5

The body 1 of the outlehhas two re cesses, one of which is below the T-slot. A terminal plate the terminal 6" binding post 7 as shown in Fig. 10. i
