DETONATOR PACKAGE.
Application inea February 5, Am5. seriai No. 7,162.
Thisinvention relates to prepared detonator packages utilizing a detonator of the electric ignition type.
In detonators of the type referred to, the detonator, cap cartridge or-shell is loaded with a high explosive vWhich is electrically ignited; accordingly the cartridge has attached thereto leading in or igniter Wires for the purpose' of conducting the igniting current thereto in order to etfect`ignition of the charge. The igniter Wire is usually of considerable length and since the cartridges must be furnished with the Wire attached thereto7 the handling and shipping of the same is rather inconvenient.
A detonator cartridge is subjected to shockselurin'g handling'and shipmentI and it frequently happens that explosion takes place 'during such handling or shipment with liability of injury to life and limbs and damage to property. Accordingly for shipment these detonators must not only be carefullypacked, but the accident, express and freight rates are unduly high.
In a detonator of the character described., 'I
the wire, including the bare terminals thereof are subjected to exposure; accordingly if they should of current, explosion of the detonator is liable to take place.
@ne of the objects of this invention, thereforefis to provide a prepared package in which the detonator cartridge and the igniter wire attached thereto are assembled to provide a compact and convenient package which can not only be readily stored and shipped, but also When required for use is so constructed and arranged as to permit the wire to be readily strung out for the purpose of connection of the Wire to the source of current, While the cartridge itself is in detonating position Another object of this invention is to provide a prepared package in which the detonator cartridge has a protective casing for completely insulating thedctonator.
Another object of this invention is to `provide a prepared package in which not only the detonator has a protective casing, but
in .which protective or insulating casing means is also provided for the wire and the terminals thereof.
Further objects will appear from the detail description taken in connection accompanying drawing,
with the in which corne 1n contact with a source y manner shown and Figure 1 is an. elevation (somewhat enlarged) showing an embodiment of a prepared detonator package embodying this invention;
Figure Q is a perspective view partly in section showing another embodiment of this invention; and
Figure 3 is a sectional View of the package of Figure 2.
Referring to the accompanying drawin and more particularly to Figure 1, (a though reference is also had to Figures 2 and 3 in that the interior construction is substantially the same when the outer tube or casing is omitted), 1 designates the detonator cartridge or shell, which as usual is of drawn metal and contains a charge of high explosive, and 2 designates the igniter wire,'which leads from andis attached to the cartridge, the wire passing through a seal 3 o f suitable materialclosing the end of the cartridge and terminating inside of the shell in a filament adapted to glow when the current is passed through the wire. his cartridge and its connections so far described may be of any usual and suitable construction, and a .further detail description thereof is, the'refore, unnecessary.
The Wire is preferably wound upon a tube 4 of paper, card board or any other suitable material, so as to provide a coiled casin which in this case encloses the tube as wel as the cartridge. The wire is preferably coiled back and forth as shown, with the outer layer helices crossing those of the inner layer and so that the cartridge attached end of of the strand both terminate at one end of the coil, and these ends of the strand preferably pass through slots 5 in the end of the tube. After the Wire has been coiled in the described, there is' left a cartridge attached end of the strand of some length, so that ,the cartridge can be inserted into the coil and the tube therein from the end opposite to which the strand is secured. While it is preferable to leave the tube in position, it will be obvious that after the coil has been wound on the tube, the latter can be taken out leaving a coil which. forms a casing, even apart from the tube; for since the coils or helices of one layer cross those of the other, the effect will be 'to cause one to hold the other, and the ends will, therefore, be secured since they the strand and the free end v double over one another, to form bights. Of course, it will be understood that the wire is insulated and is moreover of substantial cross section so as to be compara-- tively stiff, whereby the package will readily retain its shape.
In the embodiment shown in Figure 1, the bare terminals 6' of the Wire 2 are covered with a protective casing 7 of insulatingmaterial and this casing is made long enough to project beyond the ends of the wire as shown.
In the construction shown in' Figures 2 and 3, the coiled Wire has placed thereover a casing 8 in theform of a tube of paper or other suitable material. This tube can be made to closely fit the wire so as to be held in place by friction; however, after the tube is in place the ends of the tube may be crimped over as shown at 9 to provide re# tainers or stops for holding the outer tube `in place, paper caps orV wads 10 having been first put in place to close the tube 8.
In order to properly identify the terminals the Wires 2 may be distinguished in any suitable manner, as by coloring one insulated wire While leaving the other plain, or by making the insulation on the twowires of different colors. This is indicated in the drawing by cross hatching on one Wire. v
The cartridge attached strand is of sucient length to ermit the cartridge to be inserted in the tu e4 after the Wire has been coiled thereon. After insertion, therefore, there is a loop of some length which is wrapped about the coil as shown at'll by twistlng the cartridge in the tube. The-bare ends 6 may also be wrapped around the coil before inserting in the tube 8. This should be done so as to bring these ends to the 4middle of the coil as shown in Figure 2 where the Will be adequately protected andI insulated the tube 8.
It will, t erefore, be seen that the invention accomplishes its objects. A prepared package is provided which is compact convenient, simple and inex nsive, While Athe Wires and cartridge willlbia firmly' held in assembled relation; the layers of stiff wire mutually sustaining one another in order to `form a self-sustained casing, while the cartridge is retained in the casin sti cartridge-attached strands. T e casin 7 is held on the terminals 6 by friction an this can be made positive b bending or kinking the wire and casing' Where an outer-tube 8 described. i When it is desiredA to use the detonator, the cartridgp can be`withdrawn from the casing; in t e embodiment shown in Figure 1, the casing 7 is slip ed oif to expose the terminals; while in t e embodiment shown in Figures 2 vand 3 the outertube is first slipped off to free the wire. By then freeing by the A is used, it is held in place asv the strand from the slots 5, the wirecan be readily uncoiled so as to enable connections to be made to the source of current, While the detonator is placed in the charge to be detonated in the usual manner.
It will be noted that the Wire coiled around the detonator cartridge, either alone or in connection with the inner tube, provides a very strong protective casing which can withstand an explosion of the cartridge, since the rupture of the cartridge shell is lateral and usually intermediate its ends Where the protective casing covers it. The outer casing or tube 8 not only enhances the strength of the protective covering but also prevents uncoiling of the wire. This outer tube 8 furthermore not only protects or insulates the bare terminals 6 against exposure, as does the casing 7, but also protects or insulates the wire itself "against exposure; the detonator is, therefore, lnsulated against liability of premature ignition as mi ht occur if the Wires come in contact with e ectrical apparatus or current carrying Wires. Accordingy injury to life and limb during handling and damage. to property during shipment is, therefore, considerabl lessened so that accident, express and freight rates can be considerably reduced.
It is obvious that various changes may be made in details of construction without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited' to the specific details shown and described. y
Having thus described the invention, what is claimed is:
1. A prepared package comprising, a detonator cartridge having current conducting wire coiled around the cartridge to provide al protective casing therefor, and protective means for the wire.
2. A prepared ackage comprising, a detonator cartridge vaving current conducting wire, a tube over the cartridge and on which the wire is coiled, and a casing for the Wire.
3. A prepared package comprising, a detonator cartridge having current conducting wire coiled around the cartridge to provide a protective casing therefor, the terminals -of the Wire being provided with a protective casing; v
4. prepared ackage comprising, a detonator cartridge aving current conducting wire coiled around the cartridge to provide a protective casing therefor, and a tube fitting over the coiledwire and providing a protective casin therefor. y
5. A prepare ackagc comprising, a detonator cartridge aving current conducting wire, a tube over the cartridge and on which the wire is coiled, and a tube fitting over the coiled wire and providing a protective casing therefor.
