Application l love erial lilo. t

'fhis invention relates to electric plugs and it has for one of its objects the provision of a plus; comprising a pair of terminals for connection, each to one side of a power line and a fuse held a by the plug and connected to one of the terminals whereby, when said fuse is blown, only one, or

at the most, a few lamps or another electrical device will be affected, instead of having a com paratively large number or electrical. devices af= in fected, as when a fuse is employed in an electrical circuit, feeding a large number of electrical devices.

Other objects of the invention will be appreciated from a reading of the following specifics,


The invention will be fully and comprehensive 1y understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms part of the application, with the understanding,

however, that the improvement is capable of errtended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made there= from as do not affect the spirit oi the invention nor exceed the scope thereof as expressed in the appended claim.

In the drawing:

Fig. l is an elevational view partly in section of a plug embodying our invention;-

Fig. 2 is a vertical section taken on the line it of Fig. 1 looking in the direction ol the arrows;

Fig. 3 is'a horizontal section taken approximately on the line 3-3 of Fig. 1 looking in the direction or the arrows; and

Fig. 4 is an elevational view partly broken away of another form of plug embodying our invention.

Referring to the drawing for a more detailed description thereof and at first to Figs. 1 to it, inclusive, the numeral 5 indicates a shell in which is screwed an insulating plug 6, having terminal prongs 7 and 8. The plug 6 carries clips 9 and ing plug member of cross-sectionally circular 7 *1. s" era, one

which together hold to the plug a fuse ii, the clip lo being connected to the prong ii and the clip 9 connected to a lead wire 12 which passes through aperture in the shell The prong i is connected to another lead wire is.

Reierrii new to Fig. i, the numeral 15 in= dicates a which holds screw shell it with in which contained a block i? forming part of the oody of the device. A lamp 1% is screwed into one end or" the shell '16 and contacts with an end 19 of a fuse 20 which is removably held in the block 1?. The :iuse 20 has an end 21 adapted to form one terminal of the device, it being understood that the shell it constitutes the other terminal, the terminals being. insulated by the block 17. The end 21 of the fuse 20 in provided with a peripheral recess 22 engaged by an annular rib 23 formed on a tubular member 24 which is secured to the block 1?. The engagement of the rib in the recess 22 holds the lose 20 in place, the fuse being adapted to be withdrawn. iroro position by spring action oi the annular rib What is claimed as new is:

A fused plug comprising an. upwardly taper= to form, said plug member being provided with spaced prongs embedded therein of which the extremity of one is extended to the surface of the plus; member and formed into a binding post inset in a recess of said plug member, and the other is extended to e. comparatively large recess in said plug member and formed into a spring clip therein, a second spring clip disposed in said recess, a binding post set in a further recess of said plug member and electrically connected with the last said clip, said clips being arranged to jointly support a cartridge fuse within the periphery of said plug member, and a shell onclosing all but the bottom face 0! said plug memher and having a threaded connection with the to plug member adjacent the bottom iace.
