Description

A magazine strip for completely burning unencased propellant charges for industrial military purposes This invention relates to a magazine for completely propeilant charges for industrial military Completely unencased propeilant charges are known in the form of pressings of various for example in the form of strips and so In some propeilant charges of this kind can be dangerous because they catch fire fairly easily and if enclosed can even be The dangers Involved are particularly serious in cases fairly large numbers of the propeilant charges lie immediately adjacent one another for example when they are accommodated loosely in a common packing box or the It has also been proposed to provide a concatenated series of propeilant charges for a pulse socket meter on which a plurality of discrete propeilant charges are mounted on an elongated flexible strip of electrically rupturable material and a second similar strip is bonded to the former and forms with it domed capsules which enclose the propeilant When such a strip is introduced into a tool or weapon in which the chargoe are to be the domed capsules do not themselves provide a seal for the firing for which reason a slide or the like movable sealing member has to be which has to move to and fro in on the one to allow a domed capsule to pass on the other to seal the chamber behind the This the tool or weapon more more difficult to and more prone to object of the invention is to overcome the aforementioned disadvantages which are particularly unacceptable in the case of propellant charges for industrial the invention provides a magazine for completely propellant charges in the form of a preferably flexible rollable band of thermoplastic synthetic resin or the provided at intervals with recesses each designed to accommodate a propellant wherein the band has substantially uniform width and thickness and its thickness at least equal to that of the propellant In this the propellant charges are kept apart from one another so that it is impossible or at least very difficult for combustion to spread from one propellant charge to the next the distance between the individual charges of governed by the type and size of the and the requirements of the tools or weapons with the magazine is to be the band is so dimensioned in regard to width and thickness as to meet the particular requirements imposed on it by the tool or and in particular so as to pass with a tight fit through the magazine inlet of the tool or whereby special tightening means can be dispensed The propellant are with advantage accommodated in the magazine in such a way that they are in the recesses through more or less firm force In or is possible according to another aspect of the invention to arrange a readily detachable foil as a cover of In addition to optional function of holding the propellant charges in these foils protect the propellant charges against influence of hoat and To prevent the foils from with delivery of the into the they with advantage in the form of flexible and reliable for from thermoplastic synthetic foils may to band by a prevent the propellant charge from sticking to the detachable the adhesive is applied to the band than to the foil so that there is no adhesive around the Do enable the propellant charges to be delivered easily and practically into the chamber of the tool or weapon by means of the the invention further provides for the arrangement on at least one side of the ban of projections recesses facilitate or ensure the manual or It is of advantage so to dimension the of the magazine band that the recesses for the propellant charges are just large enough to permit combustion of the propellant charges and accordingly themselves form the combustion or firing There is thus no need for the propellant charges to be carried by special measures from the recesses into the firing chambers of the tool or instead it is sufficient to by appropriately regulating the magazine the recesses successively occupy in the tool or weapon the positions in which the propellant charges are subsequently tho invention by way of in the accompanying drawings 1 is a perspective view of a portion cut out of a magazine 2 shows similarly a is a fragmentary longitudinal section through a portion of the magazine band covered by 4 is a perspective view of the magazine of 3 showing the foils in the course of 5 shows in section a magazine in the couroe of being fed into the firing chamber of a and 6 and 7 are two examples for the combined application of propellent charges and According to the magazine is in the fora of a flat band 2 along its has tho recesses 1 arranged one behind the othor at appropriate intervals Accommodated in the for is a propellant charge 3 whose shape is designed to match that of the recesses Arranged along the edge of the band there are recesses 5 serving to regulate the feed of the magazine into a tool or Instead of the recesses it would of couroe also be possible to provide corresponding in case corresponding measures would to be taken in the tool or it is not only possible to provide recesses which lie directly one behind the othor along the band but also to arrange theoe recesses offset relative to one another across the Allowance would of course have to made for this staggered arrangement of the recesses in the delivery of the band and hence the According to rectangular propellent charge 3 has been inserted into a circular recess of the band 2 and the charge is held in the recess through a fit at its corners Other forms for the recess also for the propellant charges are of course According to the recesses in the band 2 are covered on both sides by means of foils foils should be readily They can be fixed to the band by means of a adhesivo applied to the band As shown in the foils 4 are preforably flexible optionally even They may be made from a thermoplastic synthetic metal or the As shown in the foils 4 are in the course of being detached from the band 2 and wound on to the rollers 6 so that in the portion of the band 2 delivered into the firing chamber 7 of the tool or weapon which has only been diagrammatically the propellant charges are As the magazine band continues to move the foils 4 continue to be wound on to the rollers so that the following recesses 1 with the propellant charges uncovered and the charges can be removed freely from the recesses 1 by which have not been and forced into firing chamber The empty band emerges from the other side of the tool or According to 6 and the propellant charges 3 are combined with bullets 8 according to could be replaced by bolts or the As shown in the propellant charges 3 and the bullets 8 are combined by foils 4 on both its flat According to 7 the propellant charges 3 and bullets 8 separated from one anothe which oan be achieved as illustrated by means of a thin intermediate web machinod out of the band 2 between the charges 3 and the bullets or by accommodating one propellant charge and one bullet successively but not interconnected in a recess from one to the other flat of the
