in carrying out my invention i will first refer to the exploded view where the several parts making up the electric plug are individually shown in elevation . these several parts i will refer to as an inner body a that will receive the two electrode terminals b , and c , and a pivoted &# 34 ; ground &# 34 ; electrode or terminal d in a manner presently to be described . a cover disc e for the inner body a is also shown and to the left of this cover disc is a split terminal carrier f with an integral spool g with a spiral groove 1 for receiving a &# 34 ; ground &# 34 ; wire h for the plug when the wire is not used . the spool g , is hollow and receives a plug cable j that in turn houses the usual two wires and a &# 34 ; ground &# 34 ; wire . a collar k also receives the cable and is threaded into a threaded bore in the spool g . the inner body a with its electrode terminals b , c and d , is received in an end cap l , and these terminals normally project through openings provided in the closed end of the cap . the split terminal carrier is also received in the cylindrical portion of the end cap l while a top cap m has an opening for permitting this cap to be moved past the collar k , and spool g , and to house the split terminal carrier f and hold it in contact with the disc cover e . the top cap m has an internally threaded cylindrical portion 2 , see fig2 that is threaded onto a threaded portion 3 of the end cap l so as to interconnect the two and to house the inner body a , the electrodes b , c and d , the disc cover e and the split terminal carrier f , as shown in fig3 . i will now describe each part of the electric plug in detail and will start with the inner body a , see fig3 to 6 , inclusive . an end view of the inner body is shown in fig4 and longitudinal slots 4 and 5 receive the electrode terminals b and c , shown in fig2 and these two electrodes project through aligned slots in the end cap l . in addition the inner body has another longitudinal bore 6 for receiving the pivoted &# 34 ; ground &# 34 ; terminal or electrode d , and fig3 illustrates how this electrode when in operative position will extend through an opening 7 in the end cap l . the same fig3 shows a diametrically extending groove 8 in the inner end of the body a for receiving the &# 34 ; ground &# 34 ; terminal or electrode d while fig5 shows the electrode d , in the groove 8 when the electrode is swung about its pivot 9 into an inoperative position and is concealed in the end cap l . to accomplish this the body a is temporarily removed from its end cap and the electrode d is swung into the groove 8 after which the body a is reinserted into the end cap l , and held in place by the top cap m . an enlarged perspective view of the &# 34 ; ground &# 34 ; electrode d , is shown in fig1 . when the &# 34 ; ground &# 34 ; electrode d , is in inoperative position as shown in fig5 i show novel means for electrically connecting the retracted electrode to the &# 34 ; ground &# 34 ; wire h for the plug . an anchor sleeve n , with its integral spring clip saddle 10 , see the enlarged perspective view in fig1 , has its sleeve portion received in a bore 11 provided in the inner body a , see fig4 . the saddle portion 10 , see fig3 and 5 is received in the groove 8 and when the &# 34 ; ground &# 34 ; pivoted electrode is received in the saddle , there is an electrical connection between the electrode d , and the sleeve n . fig9 shows an enlarged view of a split terminal p , and this terminal is connected to the &# 34 ; ground &# 34 ; wire h for the plug . fig7 shows the split terminal p carried by the split terminal carrier f , and the spool g receives the &# 34 ; ground &# 34 ; wire h . fig5 illustrates the split terminal p received in the sleeve n and when the pivoted electrode d , is received in the saddle 10 it will be in electrical connection with the &# 34 ; ground &# 34 ; wire h . therefore , fig5 shows the wire h , unwound from the spool g , and connected to the electrical outlet box partially illustrated at q in this figure . the inner body a has a pair of longitudinally extending and spaced apart bores 12 for receiving the two guide pins 13 that project from the end of the split terminal carrier f , see fig4 and 7 . however , the cover disc e , shown in both fig2 and 7 , is placed over the end of the inner body a , and the terminal electrodes b and c , plus the pivoted &# 34 ; ground &# 34 ; terminal d , are positioned in the slots 4 , 5 and bore 6 , and the inner body is moved within the end cap l before the cover disc e , is placed in position . also the cable j has been fed through the top cap m , the collar k , the central bore in the spool g , and split terminal carrier f so that its three wires can be received in the three radial grooves 14 in the face of the split terminal carrier f , as shown in fig7 . these three wires from the cable j , are then received in three peripheral notches 15 in the cover disc e and then the ends of these wires are received in three slots 16 in the inner body a , and are connected to the correct binding posts 17 for the electrode terminals b and c , and to the binding post 18 for the pivoted &# 34 ; ground &# 34 ; terminal d , see fig6 . the cover disc e is next moved against the adjacent end of the inner body a , and is secured thereto by a center externally ribbed pin 19 , see fig8 that is passed through the center opening 20 in the disc and is driven into the inner body . the cover disc e has three openings 21 which register with the binding posts 17 and 18 , see fig7 and a screw driver bit , not shown , may be inserted into these openings to tighten or loosen the screws associated with the binding posts 17 and 18 . each of the three radially extending grooves 14 has a yoke - shaped projection 22 for receiving the wires from the cable j . the cover disc e presses the wires into these projections 22 and holds them in place . when the split terminal carrier f , is moved into position against the cover disc e , the split terminal p , is moved into the anchor sleeve n so as to make electrical contact with it . the cover disc has an opening 23 through which the split terminal is moved as is shown in fig7 . also the two guide pins 13 on the split terminal carrier f , are passed through the two openings 24 in the cover disc e before they can enter the two bores 12 in the inner body a , see fig4 . the &# 34 ; ground &# 34 ; wire h from the split terminal p , see fig9 is passed through an opening , not shown , in the split terminal carrier f and when this wire is not used , it is wrapped around the spool g , see fig3 and 7 . a metal clip 25 is attached to the free end of the wire h , and the spool g , has a yoke - shaped projection 26 , see fig1 for receiving the wire and holding it in inoperative position . the top cap m , is now screwed onto the end cap l , and the two caps will entirely enclose the inner body a , the cover disc e , and a portion of the split terminal carrier f . the collar k , is screwed into the threaded interior of the spool g . the device is now ready to be used . when the &# 34 ; ground &# 34 ; terminal electrode g , is to be used with the electric plug , it will project from the plug as shown in fig3 . the &# 34 ; ground &# 34 ; wire h , is not used in this instance . however , if the electric outlet q , see fig5 is not manufactured to receive the &# 34 ; ground &# 34 ; terminal g , it is folded into inoperative and concealed position as illustrated in this figure , and the &# 34 ; ground &# 34 ; wire h , is unwrapped from its spool h , and is connected to the electric outlet q . i have already described how the swinging of the &# 34 ; ground &# 34 ; terminal g , into the saddle 10 of the anchor sleeve h , will electrically connect this terminal to the &# 34 ; ground &# 34 ; wire h , through the anchor sleeve and the split terminal p .
