(Cl. 1ML-37.8) . Fusee caps, as heretofore constructed, consisting of a utes. Y The cardboard covering 10 is burned up at the same hollowedout wooden plug held in place in one end of a cardboardv tube by means of Va wire staple, which also fastened the cloth tape to the cap, were rather expensive, rate as the rest of the body of the fusee. ' Y ` The cap indicated generally by the reference numeral 11 comprises, in accordance with our invention, a card considering the small amount of service performed there 15 board sleeve 12 to form the shank for the cap having a by, and the fact also that they did not aiford a truly de close telescoping tit on the upper end of the cylindrical pendable protection for the igniting headrof the fusee. It body of the fusee, a formed sheet metal top closure 13 is, therefore, the principal `object of our invention to im closing the upper end of the sleeve 12 and being coated prove the construction of such a cap so as to provide truly on the outside with the ignition material 8 previously dependable protection for theV igniting head, and at the 20 mentioned and carrying on its inside a cork disk 14 for ' same time make the caps available at no higher cost than protection of the projecting head 7 in the event of any the old cap construction, if as high. contact with it, and also having a cloth tape 15 suitably In the improved cap of our invention, a sheet metal top secured to the cap 11 between the metal top closure 13 closure is employed comparable to a bottle cap, having a and the cardboard sleeve 12, so that this pull tape can be cork disk inserted therein which serves for protection of 25 extended across the top of the cap 11 as a protective the igniting head of the fusee, the flange of the top clo covering for the ignition material 8, as has been custom sure being however formed to a reduced diameter so as ary with safety fusees in the past. VA paper covering 16 to grip the marginal edge portion of the disk in the is applied with glue over the upper end of the body of folded-in rim portion of the closure, and the flange being the fusee and cap 11 to fasten and conceal the cap com Y 4inserted in one end of the cardboard sleeve with one end 30 portion of the cloth tape and the flange swedged outwardly while the projecting rim portion is swedged downwardly pletely except for the protruding pull-tab defined by the small 'end portion of the tape 15, as seen in FIG. 1. Thus, the fusee is fully protected for shipment and storage and handling up to the time it is to be used, when the tape 15 is pulled upwardly, tearing the paper covering 16 length and inwardly to fasten the closure to the cardboard sleeve and at the same time grip the end portion of the tape'se curely its full width between the two parts. 'In that way, ' wise, as indicated at 17, and crosswise of its upper end, as indicated at 18, so that it is a simple matter to free the cap 11 by a twist to tear the paper along the line 19, so since the cork gives sufficient protection for the igniting head on the fusee, there is no. necessity, as there was with the old construction, of `stuihng crumpled paper into the that the cap can be removed and the fusee is then ready cap as a protective bulîer for the head, and the tape is for lighting. gripped securely its full width _in the cap instead of being 40 In the manufacture of the caps 11 by machine, the cardboard sleeve 12 has a short length of the closure re ceiving end thereof flared inwardly and folded inV annu-’ at the point of fastening when it has to be pulled upwardly larly, as shown at 20 in FIG. 4, by the action of progres to tear the paper covering to expose the ignition mate sive dies, to approximately the same width as the annular rial on the top of the cap before the cap iS twisted to 45 flange 21 of the metallic end closure 13. This closure break it loose from the remainder of the paper covering resembles a bottle cap and the cork 'disk 14 therein is preliminary to the scratching of the ignition material comparable, to what are used in suchcaps'. The closure fastened only partway across in a haphazard manner with a staple, so that there is less danger of the tape ripping off against the exposed head of the fusee in the lighting 13 has a side wall 23 and a substantially flat upper wall thereof.. 27 of'a diameter large enough for closing the upper end » - The invention is illustrated in the accompanying draw 50 of the sleeve 12 and has a concentric annular flange 21 of ing, in which smaller diameter projecting downwardly from an annular FIG. l is a side view of a safety fusee, the cap of which ` horizontal lower wall 28 that extends inwardly from the is made in accordance withV our Yinvention but is con-> top of kan inner side wall 29 that defines an annular shoul cealed by the glued paper covering in the usual way, leav der on its inner side for clinching engagement with the 55 inwardly ñared portion 20 of» the'closure 13 and another ing only a short end portion of the pull tape exposed; FIG. 2 shows the same fusee with the paper covering annular shoulder on its outer side for clinching engage ripped open by an upward pull on the tape, Vexposing theV Y ment with the marginal >edge portion'of the cork disk 14, ignition material on top of the metal top closure, the the »wall 29 being disposed in spaced concentric relation cardboard sleeve being thereafter easily freed by twisting to the aforesaid side Wall 23 and connected therewith at the same to tear` the Vpaper covering so that the cap can 60 the bottom as at '30.
