iNeLosED FUSE.
Speeeation of Letters Patent.
Patented Aug. 17, 1909.
Applcaten filed Becemher 17, 1998. i Serial No. 468,003.
To all whom it' may concern:
Be it known that i, Fmrnnnren l?. POOLE,
a citizen of the Trlnited States or" America, and residing at Bridgeport, 1n the eountjf of,
Fairfield end State of Connecticut, h .ve invented a certain ne f and lnnnn'ved lnelsed Fuse, of which the i'ollo'win'ig` is a specification.'
The object of n` f invention is to nrovide in elosed fuseharing a fuse link of imw proved type, easilY assembled with the easing and caps, and adapted to be cut Without waste iii-oni sheet nietal.
ln'ibe accompanying drawings in Which in; inventirm. is illustrated, Figure l is a ',.ross section elf a cart-ridge fuse showingl my Iinprrfved style oi' fuse link; `Figs. 2 and 3 are `lections onjthe lines 2 2 and 3-3 respec- Uivel'jv", Fig. i l: 4 is a side elevation ofthe lnse link in 'another forni; Figs. 5 and 6 are sections on the lines 5-5 and @-6 respect* tively, Fig. 4; and Figs. 7 .and 8 are perspective views of the fuse links shewn in Figs. l and el resi'ieotively.
The usual inelosingr sheath A of insulating material is shown in Fig. with Contact ea' s B and. conducting reds O between which this link l) extends. ln my improved form this link D is made from strip oi'inetal eut awavr on both sides y and frein eaeh end tewerd the middle te form blanl-approximating in appearance supergesed triangles, the upperv inverted, joined at their apexes. The fusing point of theiink .is thus termed at' the meeting ci the apexes of the triangles. Before mounting the linr. on the buttons c et the eenducting rods C, l roll up It is immaterial Whether the ends be rolled in the seme direction or not. Thus in Fig. 1 the left hand end is rolled up and the right hand end down. In Fig. l both ends are rolled up.
Other variations oi forni will readily suggest themselves. l
rlhis construction is advantageous because iirstly it permits of employing a Wider strip I metal in a cartridge oi' given diameter than' Would be possible were the blank not rolled as described, secondly the blanks may be shaped so as to be out Without Waste frein large sheets of metal, and thirdly the rolled. ends are readily fitted and held in the buttons c While soldering or otherwise securing the saine-together. Again'tlie granular niaterialE may be plaeedin the fuse after the same has been completely assembledA with the exception of one cap, as distinguished trein the tubular links which must be filled before they are secured between the buttens c.
l elaini as my invention:
An inelesed'fuse having s sheath with oor.- ductors and between the Conductors a link piece," the edges of which are out away to forni rinsing point, intermediate the ends and the latter rolled, substeJnt-ialljY as described.
