11 Claims. (Cl. 272-27) My invention relates to explosive joke devices of the type in which the opening of a cover or closure member by an unsuspecting person will result in an explosive report. The invention concerns particularly the application of explosionproducing means booklet or package for within the well-known paper matches to that when the upper or closure flap is withdrawn from underneath the match striking flap,

the mechanism will be automatically released to strike a cap for producing the explosive report.

In accordance with my invention the package or cover, which would ordinarily have'secure'd therein the stub from which the matches extend, will instead have secured therein a flat frame preferably of paper which may simulate theappearance of the match stub and matches and within which frame is supported and arranged the explosion producing-mechanism.

In the device of of the package or in closed position 'my invention the closure'cover booklet, when frictionally held by the match striking flap, will serve to hold the spring operated cap striker mechanism in set or tensed position to be released for striking action as soon as the pack age cover is withdrawn from the striker flap by the personwho believes he is opening a match package or booklet.

gement; and

match striking substance 12'is IlI--III of Fig- IX-IX of Figusually made from a form the lower front closure or cover flap 14 hich, when in closed position, is parallel with the back ,15' of the package; Ordinarily, paper stubs with matches extending therefrom are securedbetween the back 15 andthe lower flap 11' with'a rivet extending (1 throughthe stubs and the back and the flap, the end of the closure flap 14 being inserted between and frictionally held. in'closed. position by the stubs and the flap 11. For the purpose of my invention Isubstitute for the-stubs and matches a rectangular frame. F preferably 101" paper and preferably built up of two or more laminations 16 so as to simulate the stubs and matches extendingtherefrom/ The frame'F. has the rectangular opening 1 'cut therein for receiving a shallow box or enclosureB for the operating parts of. the explosion producingmechanisin- In the arrangement of Figures 1 to 7 the box, which is preferably of comparatively thin sheet metal, comprises theback' or bottom: 18 with the iongitudinal. side walls 19 and- 2ll "defie'cted there'- froni; The box is of a depth to fit into the opening 1'7 with its side walls 19' and 20 engaging against the sides of the opening and the upper end 21 of the back 18 extends a distance beyond I the side walls torengageagainst the back .of the frame F, a 'cl'ampingea'r 22 extending from the end 21 to be clamped around the upperedge of theframe F and-against the front thereof above the 'op'eningl'l as clearly shown in Figures 4, 5 and '7. The lower end 23 of the back18 is narrowed and. at'vits lower-corners has clamping tongues or earsv24 extending upwardly for pro: jecting through slots 25 in the lower-edge of the frame F and to extend also through the match striking flap 11 and to be deflected against the front side of said flap sothat the'flap issecured to the-frame' The lower end of the box 3 is closed by the lower-end wall 26 which has tongues 27 extending froin' its upper edgeand deflected 95 downwardly against the front face of the frame FY,L tonguesl28 extending downwardly from the lower edge of: the end wall extending through. the back 15 of the package and being deflected against therear face of thewall to thus secure the frame and box to the rear wall 15, The tongues 24 and. 28- thu-sftake the place of the usual rivets or clamps in theordinary match booklet for securing the match -holding stubs to the booklet back and thematch striking flap.

Intermediatetheir ends the side walls 19 and 20 of the box B are apertured to receive a pivot pin 29; theframe F having therecesses 30 for receivingtheends ofthe pivot pin and to prevent longitudinal displacement thereof. Hinged on the pin 29 is the striker plate 31, the portions 32 of the plate being bent around the pin for bearing thereon, and between the parts 32 the pin 29 receives the coiled spring 33 whose one end 34 abuts the back 18 of the box B and whose other end 35 abuts the striker plate 31, the spring tending to swing this plate downwardly against the bottom of the box. At its free end the plate has the circular deflection 36 forming a hammer head for engagement with an explosive cap 37 placed in the cap pan 38, this cap pan being circular and being secured to the bottom of the box B by means of tongues 39 extending through openings 40 in the box bottom and deflected against the back of the box. The plate 31 is provided with a lug 41 under which a fingernail may be inserted for swinging the plate back against the force of the spring when the device is to be loaded.

At their upper ends the side walls 19 and 20 are apertured to receive a pivot pin 42 for hinging at its upper edge the holding plate 43, the frame F having the recesses 44 for receiving the pin ends and preventing longitudinal displace: ment of the pin. When the striker plate 31 is swung upwardly against the force of the spring 33 and into the box, the hammer deflection 36 will be adjacent to the hinged end of the holding plate 43 so that when this plate is swung down to closed position and against the hammer deflection, comparatively slight pressure against the ends of the holding plate will serve to retain the hammer plate in its set or tensed position within the box. When the closure flap 14 of the package is swung down against the holding plate and is inserted between'the frame F and the striker flap 11, it will be frictionally held in closed position and against the holding plate to retain the holding plate in closed position and the striker plate set. However, as soon as the cover flap 14 is released from frictional engagement between the frame F and the flap 11, it will no longer retain the holding plate 43 against the force of the spring 34 and the released spring will rapidly snap the striker plate 31 downwardly and holder plate upwardly. When the striker plate is thus snapped downwardly by the spring, its striker or hammer deflection 36 will strike the cap in the cap pan to fire the cap with a loud report.

It will be noted that, when the holding plate 43 is down in set position, it extends substantially entirely across the front of the box B and closes the box. Now, when the holding plate is released when the closure flap 14 is withdrawn, the force of the tensed spring 33 acting against the striker 3 plate to swing and snap this plate downwardly will also rapidly swing the holding plate outward.- ly, and this plate will strike against the adjacent edge of the frame F at the opening 17 and will be recoiled to rapidly swing back to closing position, such closure movement of the holding plate being sufilciently rapid to reclose the box F toprevent any escape therefrom into the open of sparks or particles of explosive material resulting from explosion of the cap, and the opener of the device will thus be fully protected. To assist the movement of the holding plate to closing position, a comparatively light coil spring 44 could be mounted on the hinge pin 42 to abut at its ends against the frame F and against the outside of the holding plate. Such spring would assist the recoil movement in rapidly restoring the holding plate to box closing position but would not have sufficient strength to interfere with the proper functioning of the spring 33. Thus the device, while affording considerable amusement, is entirely safe.

In Figures 8 and 9 I have shown a modified arrangement which would simplify the construction and reduce the cost of manufacture. In this modified arrangement a plain rectangular sheet metal box 45 is employed without any extensions on its back wall as in the arrangement of Figures 1 to 7 for supporting it to the frame F. Instead the pivot pins 46 and 47 for the striker plate and the holding plate respectively are relied upon to securely hold the box 45 in proper position within the frame opening 1'7. As shown, the frame is made of two layers 48 and 49 between which the projecting ends of the pins 46 and 4'7 are applied and the layers then intimately secured together as by means of glue or cement 50. A rivet 51 is then applied through the package back 15, the lower part of the frame F and the striker flap 11. In all other respects the structure may be the same as that in Figures 1 to '7.

I have thus produced a device of the class described which can be economically manufactured, which will aiford considerable pleasure and amusement, and which can be operated without injury to the user. Further this device is a single unit and is flat so that it may be readily inserted in or under the desired object or element to be raised, lowered, or otherwise moved by the party on whom the joke is being practiced.

I have shown and described a practical and efficient embodiment of the features of my invention, but I do not desire to be limited to the exact construction, arrangement and operation shown and described, as changes and modifications may be made without departing from the scope of the invention as defined in the appended claims.
