Application tiled December 30, 1916. Serial No. 139,878.

' To all whom it may concern:

Be it known that l, (TIL-nines A, VIL- ing aronud its interior circumference and in position to recelve the heads of the rivets &

mans, a citizen of the United States, and a and permit them to rotate with the member resident of Brooklyn, in the county of Kings and Stute of New Yorlg, have invented certain new and useful" improvements in Multiple-Fuse Carriers, of which the following isa specification.

I This invention relates to improvements in multiple fuse carriers or cartridges in which a plurality of fuses may be carried, so that p---when one fuse burns out another may be "-quickly and easily brought into position and the circuit at once restored, the object of the invention beiiw to provide a device of this "struction and inexpensive to manufacture and easily operated,- and to provide a combination-of parts whereby the liabilitvut destruction of the cartridge on the blowing In the drawings accompanyingand' form- '"plan -view showing the loaded-cartridge sccured in position for use; 1" 1g. 2 s an end 'view of F g. 1; F 1g. 3 IS a longitudinal secing part of this specification, Figure 1 is'a tion (ii-Fig. 1; Flg. 4 is a cross-sectional view taken on the line 4-4, Fig. 1; Fig. 5

improved fuse carrier or wands: consists are cylindrical member 2 fori'ned 'of some suitable non-conducting material, in' which aresecurcd a plurality of fuses 3 (four be- '---'ing "sh'own herein); The fusw are secured to f the'jmemlmr 2 at each end-thereof in any sni-table nnumer, as for instance by'=ineans of rivets 4, the heads of which pro ect'at the exterior of the member 2 and act as contact forming members for said fuses. The member 2- is inclosed within an exterior shell or casin 5-adapted to snugly lit the member 2,

but to'permit rotation thereof'ivithi'n said shell. The shell 5 is provided adjaoentjo each end thereof with a groove 15 extend- A pair of end members or ca'ps 7, formed of a suitable metal, are provided for closing the ends of the cartridge, and which caps are adapted to lit over the ends of the shell or casing 53, the caps 7 having. secured 'thereto suitable brackets 8 for attachment to any suitable support in position for use. Each of the end members'or caps 7 has punched from the metal thereof a tongue 9, which is formed and pressed inwardly as to project into a cutout portion or recess 10 iii the end of the casing or shell 5 and form contact with whichever fuse is located in position so that its rivet is within said opening 10, The shell 5 is also provided with a small opening 1 near one end thereof, and ,the inner rotatable member 2 is marked on the extw'ior thereol' directly over the point where each fuse is located with some suitable indicating character which will appear in said opening 1 when the uiem'lwr 2 has beenrotated as to bring one of the fuses into contact with the tongues carried by the caps. The tongues 9 and openingslo also perform the function of forming.a positivo stop to prevent the rotation of the-shell 5 rclati'velv to the caps 7 when the inner tubalar member 2 is rotated within said shell.

- The -fuses herein shown are formed of copper ends, as 12, united by a center por- -tion 11 of a softer metal, such as a compound of lead and antimony, said center portion being offset from the cartridge, as

shown clearly in Figs. 3 and 5, and in case of a blowout the weaker center portion of the fuse will bletth'.

,The cartridge 2,. after having the required number of fuses riveted therein, is tilled with asbestos powder, which will lill in the space lnetwecn the wall-of the-cartridge and the center portion of the fuse, so that when a i: use is blown out ignition of any portion of the cartridge is prevented byreason of the fact that the asbestos powder will immediately fill'in any space that is'caused by the blowout, and the ends of the cartridge are closed by means of .a pair of asbestos'dislm i3, which are perforated, as are also the end 5, the shell will be held against rotation relatively to said caps, and by taking hold of the inner member 2 through the openings 6 in the shell 5 the member 2 may be rotated until one of its fuses is in contact with the tongues 9, which is indicated by the appearance of the indicating characterin the opening 1 in the shell. It will thus be seen that when a fuse has blown out, all that is necessary is to take hold of the cartridge 2 through the opening 6 in the shell and rotate said cartridge a short distance thereby to bring the next fuse into position to contact with the contact members or tongues 9.

It will be understood, of course, that I do not desire to confine myself to theidentical details herein shown and described, but'that the same may be modified more or less without departing from the spirit and scope of this invention.

I claim as m invention:
