MEANS, Fon IGNITIN@ Fuses.

To all whom it may concern:

Be it known that I, Surnom* LILLEY, a citizen ot the United States, residing at Deepwater, in the county of Henry and State of Missouri, have invented'a new and useful Means for lgniting Fuses, of which the following is a specification.

This invention has reference to means for i niting fuses and is designed to provide a cevice whereby a number of fuses may be ignited at one time either by an operator located ata safe distance'from the igniting means 'or by an operator located at the igniting means in which case the fuses will be of suiiicient length' to permit the operator to reach a place of safety before the fuses shall burn to the explosive to be irld.

cone there is a circlnntverential series of perrEhe invention is designed for use in blasting where a number of differently located blasts are to beliredand in accordance with the present inventionprovision is made for producing an 4intense heatby the ignition of a mass of material of such nature as to surely ignite the fuses which then will burn individually to' the charge to which they lead. y

The invention will be best understood Y from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification, in which drawings,

Figure l is an elevation of the igniting device. Fig. 2 is a section of the same on the line A-B of Fig.'].. Fig. 3 is a section on the line C-D of Fig. 1. Fig. fl is a section similar to that of Fig. 2 but showing a slightly modified form. Fig. 5.

is a section similar to Fig. 2 but showing still another modified form. Fig. 6 is a section of still another modified form.

Referring to the drawings there is shown a casing 1 which in the particular showin of the drawings is of double truste-conica shape with the bases o't the cones adjacent and the smaller end of the shorter conical section constituting the support for the device. Near the bas'e of the upper or larger forations Q designed to receive the ends of a suitable number of fuses 3. The double conical form of the casing provides for the elevation of the fuses above the ground or other support upon which the device is placed so that as the fuses burn awayv they will not drop against the side walls of the Specification of Letters Iatent. Application led December 6, 1909. Serial No. Atllt.

lWithin the casing and concentric with'thc' central longitudinal axis thereof is a tube- -L resting on al plate 5 which may be located 60 coincident with meeting edgesof the faces j of the two conical portions of the casing l.. This tubular member 4.- is' closed at its lowerv end by 'a plate 5 and is open at the other end vwherev -it may be threaded for the' re- J5 ception of a screw plug 6 having the inner end reducedlin diameter as shown at Z to receive onev ,end of a cylindrical receptacle 8 the other end 9 of which is tapered toa small opening l() the size of which latter is exaggerated in the drawings -for clear-nessi of illustration. 'Within the receptacle 8 there is provided a needle valve 1l closing' the opening 10 in which it normally'engages by gravity. This needle valve isprovided with av stem 12 extending through the plug or closure 6 so that its end removed from the valve 11 is accessible to the operator.

By placing in the tube l a suitable compo- '.80

sition, preferably a mass composed ofehlorate of potash and sugar and by placing a. quantity ot sulfuric acid in the receptacle 8, in which latter it is heid-'by the valve 11,

theseveral parts being made of materials 35 unaffected by sulfuricI acid, then when the operator desires to lire the fuses with theirv ends already introduced through suitable perforationsv in the tube 4 matching the perforatioiis 2 in the casing 1 and extending 90 to the mass of material therein indicated at 13. the operator has but to lifttlie valve 11 when a small quantity of sulfuric acid will lind its way into the mass 13 and by the` violent reaction there set u-p will cause the 175 extending to the distant point desired. 1

ignited, the ignition of the and not V all brought together in order to cause igni- .the mass 13 an For instance the casing 1 may be located at the bottom of a mine shaft and the wire 15 may extend to the surface of the ground above.` "in such cases a cartridge 16 which may consist' of a fragile tube containing sulfuric acid is ermitted to gravitate along the wire 15 and) will then enter the tube 4 the outer end 'of the tube in this instance being free from the .plug 6, and on reaching the mass 13 the cartridge 16 if of a fragile nature will engage the hook 14: and become shattered thus s illing the sulfuric acid into causing the ignition of the latter. li' desired the tube 16 may be similar to the receptacle 8 and contain a valve 11 which will be opened by engagement with the hook 14:I or even with the mass 13 if the latter be suiieiently compact. By this means no electric current is needed nor is matter which isj'readil ignitable by ordinary handling or whici requires the pres ence or' a flame to lcause ignition at all needed.l

The materials mentioned, namely chlorate of potash, sugar and sulfuric acid must be tion and consequently there isv no danger of premature ignition as sometimes takes place with electric current nor is there the conslant' danger of fire as occurs if niatches or other igniting materials are employed. Again the ignition may be controlled from any. desired distance without dependin upon the pulling of cords' or wires anc only depending upon the action of gravity 'to' cause the cartridge or receptacle 16 to move into the tube f1.

i Any number of fuses 3 vmay be used from one to as high a number as the receptacle j considerable distance into the tube 4.

1 may receive and an' equal number ofblasts may be set oft, the time between the ignition of the fuses and the explosion of the blasts depending upon the length and character of the fuses. If it be desired to discharge the blasts by short fuses then the iignition of the composition 13 may take place by perinitting the receptacle 16 to move from 'a 1f however the fuses are quite long then the 'c erator may release the sulfuric acid into t e. mass 13 at the'casing, finding ample time to reach' a safe place-because of thetime taken by the fuses to burn to the blast.

The operator may pour the sulfuric acid directly from/a lcontainer 17 into the mixture in the 'tube 1i, as indicated in Fig. 5, in

which case the fuses are made long enough to allow the operator to reach a place of safety.

The mixture 13 may be vinclosed in a small casing 18 of suitable material say thin metal and a capsule 19 is embedded in the mixture 13, the capsule containing the acld.

^ One end of a fuse 3 is inserted into the casing so as to reach the mixture 13. The capsu e 19 may be made of glass or other fragile material so as to be ruptured by a suiiciently heavy blow delivered on the casing 18 to cause the ignition of the mixture 13 and by f the latter the lighting of the fuse 3. The small casing 18 may be used in. situations where the larger structure o Figs. 1 to 5 cannot be used.

The mixture of chlorate of potash and sugar is improved andprevented from caking by the addition of powdered graphite.

What is claimed is:

1. A device for the ignition of fuses com prising a casing formed of two superposed reversed frusto cones with the bases of the cones adjacent, a plate traversing the casing at the junction o the basic ends of the cones, and a tubular member extending from 'the plate to and opening at the smaller end of the upper cone andclosedat the lower end by the plate, the basic end of the upper cone and thelower end o the tube being provided with circular series of alined holes.

2. A de'vicefor the ignition of fuses, comprising a casing formed of two superposed reversed frusto cones with the bases of the cones adjacent, a plate traversing the casing at the junction of the basic ends of the cones, a tubular member extendingfrom the plate to and opening at the smaller end of the upper cone and closed at the lower end vby the plate, the basic end of the upper cone and the lower end of the tube being provided with a circular series of alined holes, a closure for the open end of the tubular member, a receptacle carried by the inner end of the 'closure and extending into the receptacle, and a valve in the receptacle h '-ving a. stem extending through the closure o the exterior thereof.l

In testimony that I claim the foregoing as S. B. OSBURN, J Pico.
