SPECIFICATION forming' part 0f Letters Patent No. 672,650. dated April. 23, 1901.

Application iled December 20, 1900- e'erial No.' 40,503. (No modelV 'have invented n ew and useful Improvements in Miners Sqnibs, of which the following is a specification.

' f My invention relates to minerseqnibs, the same residing in a novel construction of the squib itself and of the blank from which theY squib is made;

. pletion. A

tube completely formed, wit-h the outer edge` lheobject of the invention is to provide a sqnib and the blank from which the same is produced by means of which the squib-tnbe is effectively closed at its forward end-and by means of which the fuse or match is formed integral with the said tube and projects outwardly therefrom at a short distance from the end of said tube, so that in the event of a puncture of the forward end of said tube the explosive material contained therein will not fall upon and adhere to said match or fuse.

lOtherobjects of the invention will `hereinafter appear and the novel features thereof will be set forth in the claims.

Inthe drawings forming a. part of this specification, Figure 1 is a face view of the blank from which my improved squibis made. Fig. 2 is a perspective view of the same, showing one edge of the blank rolled kupon a mandrel as the first ste in the formation of the tube. Fig. 3 is a sim'lar view showing the closingiiap for the forward end of the squib-tube g Fig. 4 isa similar view of the blank, illustrating the tube-forming operation near its com- Fig. 5 is a similar view showing the thereof pasted or otherwise secured in place. Fig. 6 is a perspective view showing the match orfuse in its twisted condition, and Fig. 7 is a similar view of the completed squib. Like reference-numerals indicate like parts in the different views.

The blank 1 is provided withfthe. parallel side edges 2 3`and with a tongue 4. and a lip or ap 5 at its forward end. The flap 5 is produced by a lateral incision 6, extending inwardly from the side edge 2 of the blank, by a longitudinal cut 7, parallel to the side edge 2 and intersecting the incision 6, and by an angnlarly-arrauged incision 8, the latter forming one of the side edges of the flap' and a portion of one of the side edges of the tongue 4. The incision S terminates at its rear end beyond the-incision 6, as Shown at 9, for a purpose which will presently appear. The side edge 10 of the tongue 4 directly op- 4posite the incision 8 extends at an angle to 6o Said incision and terminates at its rear end beyond the end of the incision 8,*as shown at 1l., From the point 1l to the side edge 3 of the blank the material thereof is cut away, as shown at 12. The lateral incision 6, extending inwardly from the sideedge 2 of the blank l, constitutes a guidefor the end of the mandrel 13, upon which the blank 1 is rolled to form the squib-tube 14. In forming,r the squib-tnbe the cylindrical 7o mandrel 13 is placed upon the upper surface of the blank 1, along the edge 2 thereof, with the end of said mandrel opposite the incision 6 `in said blank. The edge 2 is then rolled upon the mandrel, as illustrated in Fig. 2 of 75 the drawings, until the partially-formed tube comes opposite the [lap 5 adjacent tothe longitudinal cut 7, which constitutes one of the side edges thereof. The said flap is then folded inwardly, as shown in Fig. 3 of the 8o drawings, closing the outer end of the partially-formed squib-tube, andthe rolling of the blank upon the mandrel 13 is continued. 'lhis action causes the bent-in flap' 5 to be rolled between the body of the blank l. and

the outer sui-face of the partially-formed The saine is thereby securely held in place, and dangcrof accidental separation thereof from the end of the squibftube is prevented. In Fianet of the drawings the 9o lip or fiap 5 is shwnhs completely iuclosed and covered by the partially formed tube; but the rolling),l of the blank lriupon the mandrel 13 is continued until the-edge 3 of said blank approaches said mandrel. Theupper surface of theblank 1, a-djiicont to the edge 3, .then has applied to it paste orother adhesive material, and when the` blank isciompletely rolled upon the mandrel 13, as illustratedin Fig. 50E the drawings, the squib-tube is comloo pletely formed, with the edge-3 of the blank 1 pasted or otherwise secured in place. The

tongue 4has during this operation remained in practically dat condition, except, perhaps, along the line of its juncture with the body of the blank l. As the point 9, however, which is the rear end of the incision 8, is back of the incision (5, which is in line with the frontend of the tube 1.1, it will be observed that the point orlinc ofjuncture of the tongue t with the body of the blank 1 is back of and .sligl'i'tly removed from the forward e'nd of the squib-tube. The point 1l, which constitutes the roar ond of the side edge 10 of the tongue 1, is slightly to the rear of the point 9, so that the line of juncture between the tongue 4 and the body of the blank l is a diagonal one. 'lhc result of this construction is that when the tongue 4 is twisted to form the match or fuse l5 the same will connect with the body of the completed sqnib at a short distance from the forward end thereof. By extending the side edge 10 of the tongue at back to the point l1., which is located to the rear of the point 9, said tongue when thearticle is in the condition shown in Fig. 5 of the drawings will project slightly at an angle from` the squib-tube and the twisting action upon the tongue 4 will have a tendency to roll said tongue around the projecting end of the squib-tube instead of at an angle, as shown in Figs. 6 and 7.

Of course after the mandrel 13 has been removed froin the tube which was formed thereon the said tube is filled with powder or other explosive material andthe rear end thereof closed in any suitable manner. Now it will be observed that as the closi 11g-flap 5 is folded inwardly over the forward end of the partially-formed squib-tube and afterward rolled around the forward end of said tube said tube is' completely and effectively closed at its front end and none of the explosive contained therein can escape except by punctu ring said closed end. In the event-of suchgy puncture, however, and the consequent escape of the powder or other explosive material from the forward en'd of the squib-tube none will come in contact with or adhere to the match or fuse 15, owing to the fact that said match o'r fuse is out of line with the bodyv of thesquib. An

eiective closing of the tube isfthereby formed by my construction, -as well Aas an eiective means for preventing accidents due to the escape of the explosive material'frn the tube. The blank 1 may be made of tissue-paper or other suitable material, and the match or fuse 15 may have paraffin or other vsuitable slow-burning combustible material thereon. Having now described my invention', what l vI'elaim as new, and desire to secure by Letters Patent, is-

1. A miners squib having the match or fuse thereof secured to and projecting from the thereof, and coated with paraffin.

Grasso tube at a point4 removed from the forward end thereof.

2. A miners squib having the match or fuse thereof secured to and projecting from the tube ata point removed from the forward end thereof, and extending out of line with Said tube.

' 3. A miners squib having the match or fuse thereof integral with the tube and connected thereto at a point removed from the forward end thereof.

4.-. A lniners squib having the match or fuse thereof integral with the tube and extending ont of line therewith.

5. A minet-s squib having the match or fuse thereof integral with the tube, the line 'of juncture between said match and tube being diagonally arranged. i

6. A blank for a miners squid having at one end thereof, a tongue for the formation of the match or fuso, and a closing-flap, therear end of the edge of said tongue adjacent to said flap lying at-'a point back of the rear end of the opposite edge of said flap.

7. A blank fora minerssquib having at one end thereof a tongue for the formvtion ofthe match or fuscand a closing-flap, the said liap being formed by a lateral incision leading inwardly from one of the side edges of said blank, by a longitudinal. cut intersecting said incision and by a longitudinal incision Icoincident with one of the side edges of said tongue, said longitudinal incision termina-ting at a point to the rear of said lateral incision.

8. A blank for a miners squib having at one end thereof a tongue for the formation of the match' or fuse, and a closing-flap, said iiap being formed by a lateral incision leadinginwardly from one of theside edges of said blank, by a longitudinal cut intersecting 4said incision and by a longitudinal incision coincident with one of the side edges of said tongue, the said longitudinal incision terminating at a point to the rear of said lateral incision, and the side of said tongue opposite said longitudinal incision being formed by a cut-away portion of said blank and terminating at a point to the rear of the end of said longitudinal incision. 9 A miner-s squib having the match or fuse thereof secured to and projecting from the tub at 'a point removed from the forward end In testimony whereof I have hereunto set my hand in presence of two subscribing witnessest EVAN'REESE.
