Pins 28 comprise the tiring-pins lor discharging the blank cartridges 29 or detonating caps that are mounted. in suitable chambers 30, provided in a chamber bar 3l bolted to the trout ot' the plate 21 in alinement with the respective tubes Suitable coiled expansion springs 52 surroundI the plungers Z4 between the caps 23 and heads 27, and in order to insure the guidance of the firing-pins to the cartridges, the inner ends of tubes 22 are closed by plugs having central openings 34 therein for the reception of said firingins. I

At the rear of the plate 21 the tubes 22 have transverse slots 35 cut in their upper segments, that are of a sufficient width to permit ot' the insertion of the lower edge of a trigger-blade 36, and when said plungers 24 havel been pulled out to their t'ullest extent, this blade 36 is moved downward into the slots 35, whereupon the pl angers 24 may be released and the heads Q7 will press against said blade and be held in a retracted position. One end of the blade 36 is pivoted at 37 to the rear surface of plate 21 and ,its opposite end rests upon or disposed adjacent a cam or rotatable block 38 secured upon the key spindle 3f) of a suitable clockwork (not shown) within a case 40 mounted adjacent the end of the bottom wall ll opposite the firing elements. The clockwork is of ordinary construction and need not he described except to state that it is provided Awith an alarm-bell 4l and a substantially L- shaped lever 42 is secured to and movable with the spindle of the escapement pawl. The shorter arm of this lever 42 extends through an opening in the wall of case 40,

while the longer arm extends down outside the case 40 and is engaged by an angular shaped spring 43 that exerts its tension to keep the longer arm in a substantially vertical plane where the escapement of the clockwork would release the mechanism thereof and permit the same to operate,4

thereby ringing the alarm bell 41. Under normal conditions this lever is retained in the position illustrated in Fig. 2 of the drawings by means of a pin 44, extending from the outer end of the movable core 45 of a solenoid 46. interposed in the circuit in which this solenoid 46 is connected are one or more switches 47 that may be located upon the windows, doors vand other entrances or exits 'of the building and also upon counters, cashiers desks, and the like, so that the closing of the circuit will energize the-solenoid 46,.thereby retracting its core 45 and causing the lever 42 to return to its normal vertical position and release the escapement of the clockwork. The alarm bell'41 will immediately begin ringing and 5 the winding key spindle 39 will .rotate the the same.

block 3S, which in turn lifts the free, movable end otthe blade 36 so that the plungers are successively released and the cartridges `discharged in sequence.

l have found it to be desirable to release and lower the bottom-wall during the sounding` of the alarm bell and the tiring ot' the cartridges, and for this purpose it is necessary to release the latch bolt 17 heretofore mentioned, by other means than itsrespective solenoid 15. I prefer to `ulcrum a lever 4S so that it is movable in a horizontal plane substantially parallel with the plane of the axis olf the latch bolt 17, and the bolt is either slotted or has a portion of its underside cut away to provide a shoulder 49 adapted to be engaged by said lever when the latter is moved on its pivot in the direction oi. the solenoid. A comparatively strong contracting spring 50 is connected to the movable or :tree end of lever 48, in order to keep the latter normally pressed toward the solenoid, and when said. spring is permitted to exert its force, the lever will be moved against the shoulder 49 and retract thel latch bolt a distance sufficient to release light gage wire spring 51 engages the outer end ot' the latch bolt so that under ordinary conditions this spring will force the bolt outwardly and keep the same in engagement with the front wall of the casing. In order to retain. the lever 48 in set position, that is, when the apparatus is adjusted so asl to soundthe alarm and tire the cartridges, l provide a suitable l.- shaped lever 52 that is fulcrumed intermediate its ends upon the side wall of the clock case 40, so that one end will be disposed in front of and arrest the 4movement of the lever 48. The lateral member 53 olE this lever projects outwardly toward and into the path of the cam block 38, and when the latter is rotated in sounding an alarm, saidblock will operate sald lever so that the end therej oi in front of the lever 48 will be raised, thereby releasing the lever 48 and unlocking the latch to permit the bottom wall to open or drop downward as shown in Fig. 2l ot the drawings.

For the purpose ot concealing the wires, l

prefer to mount the alarm device in the angle formed by the ceiling and wall of va room, store or other structure it is desired to protect, and it will be obvious that, when one of the switches 47 is operated to close the circuit I therethrough,I solenoid 46 will instantly be energized and retract' its core 45 which is normally held at the limit of its outward movement by a wire spring 54, thus releasing lever 421, which in turn operates the escapement to start the clockwork. The bell alarm will Ting and the rotation of the spindle 3S) and block 38 will depress the ad jacent end of lever 52 sufiiciently to release the end of lever 48 engaged by its opposite tracted position` meshes end, causing the retraction of the bolt 17 and the release of the latch; at the same time the block will raise the adjacent end of blade 36 so that the firing plungers 24 will be released, one by one, to discharge the cartridges.

While have herein`illustrated and .described certain instrumentalities for carrying out my invention, it will be obvious to others skilled in the art to which it pertains, that numerous modifications and renements thereof are possible without materially departing from the spirit of my invention. 1 therefore desire it understood that all of such changes are contemplatedwithin the scope of my invention'as expressed in the appended claims.

What I claim is l. A burglar alarm comprising a plurality of cartridge-holding chambers and means for successively firing the same comprising a corresponding number of firing pinsre tractable plunger-s on which said pins are mounted, a blade movable in front of said plungers adapted to retain the same in rei and devices for moving said blade away from said plungers whereby the latterare released in succession.
