a subject of the King ofjspain, residing at; lVashington, in the District of Columbia,

have invented;certainv new and useful Improvements in Alarm Devices, of which the following is a specification. 1

Thls invention relates to an alarnidevice more particularlyv oi thattype whleh employsimeans for detonating a cartridge when the device'is operated from a set condition.

One obj ectof the present invention resides in providingl a device oi the above mentioned character which isnovel in operation in that the trigger; operating element .may be moved universally.

Another object resides in providing a discharge receiving chamber having an abutmentdisposed in the directpath of the discharged gases and having an outletsubstan;- tially parallel to the axis of the discharge receiving chamber, thus preventing the pos sibility of ignitionof exterior objects. by

the fire of the discharge.

In detail-:

The device comprises a substantially cylin drical casing A divided into compartments 1 and 2 by means ofa partitionS- The former a compartment is what may be termed the trigger mechani S111: compartment whereas the latter is what may be termed the cartridge chamber compartment. Superposedon the cartridge chamber. compartment and into-.1 gralthere'with is the discharge receiving .65 discharge of the. gases When a cartridge is fired. Directly opposite the passage 5 is locatedsthe end chamber 4. which receives,

through the barrel opening 5, the direct wall 6. of the cham'benand; hence the discharge takcs. place, directly against this end discharge receiving chamber Which, bymeans 01. a. right 8 connects with the chamber. 4 and thus an outlet for the gasesis.providediwhich has its axis substantiallyiparallel to the axis of .70. wall. Alongside of and integral with. this". is a passage 7 angular passage n the passage 5 and to the axis of the chamber 4 and by reason of its location, provides an H indirectpassage for the discharged gases.

The advantage of this is that, provided any particlescof metal or the like were accidentally included within the cartridge the c same will be discharged against the solid abutment .wall- 6, and further by reason of.

the fact that "the outletfor the discharged gases is indirectfiame will not issue directly from the chamber 4: and thus the danger of producing conflagr'ation when the device is operated, is entirely eliminated.

t Within the compartment 2 is located the 'rotatable cartridge chamber 9, which has a. plurality of apertures 10 to receive the car:

tridges which "are located in substantially radial "directions from the center of the chamber- 19. This chamber 9 is pivoted for rotationat 1010 and on its bottom carwhich will'be hereinafter described. One

side of the compartment 2 is open and one edgehas pivoted thereto-at 13. the side of a semi-circular member 14 which closes the side oi the compartmentQ and is also provided with arms 15 which carry journals 10 for the cartridge chamber 9, and thus the cartridge chamber 9 may be swung out for reloading- This member 1 1 is held, in its closed position, by means of a latch 16 which engages therewith, said latch being the pivot pin '26 is a bell crank lever 27 the lower end of said shank 17 being provided with the lug 19 having the inclined face 20 which is adapted to be engaged by a similarly inclined.face 21 of a lug 22 carried by a shank 28 journaled for reciprocation in the wall of the compartment 1 and hav' ing its knobbed end2t projecting. exteriorly of the casing, the shank of the latter member 7 being at right angles to the shank 17. The button 24: is held in its outer position by means of a spring 25 which has one end attached to the lug 22 and the'othe'r end attached to the casing, said spring being a tension spring and therefore drawing the face 21 back out of engagement with the face 20 of themember 19 until the button 2 1 is pressed, at which time the said faces engageand by reason of their inclined nature this'ac'tion serves to disengage the latch 16 from the'member 14 after which the latter member is permitted to swing outwardly.

Within the compartment 1 and carried by which, at the end of the long arm carries the cartridge firing pin 28 which is adapted to project through the aperture 12. The long arm 27, at its end, has connected therewith at 29 a lever 80 which is slotted'as at 31 to accommodate apin 32 carried by the mem ber terminating in a knob 34 exteriorly of the casing; this being for the purpose of resetting the trigger memberwhen it has once been actuated and the slot 31 provides for normally maintaining the member 3 1 in its usual position as shown in Fig. 1 even though the trigger mechanism be set or unset, by reason of the fact that the pin 32 is' slidable in the slot 81-. The long arm of the bell crank lever 27 is provided with a lug 35 in which the end of a leaf spring 36 is held, the other end being .secured at 37 to the side wall of the compartment 1, said springacting to bring the firing pin member 28 into forcible contact with the detonating cap of the cartridge'when the trigger mechanism is operated from a set position. Thetrigger mechanism consists of the shaft 36 which is reciprocable' within a suitable be'ari-ng'as shown, and'carries at its forward end the latch 87 bevele'das shown at 38,

' which when set, seats in a suitable slot. or

notch provided in the long arm of the bell cranklever '27. The shaft 86 has affixed thereto adjacent its rear end, arms indicated generally at 89, which extend radially from the shaft at approximately right angles to each other. By moving anyof the arms in a rearward direction, the shaft '36 will be retracted and the latch 87 will be withdrawn fronrengagement within the slot or notch in the lever 27 whereupon the latter will be .QIOVGtl forwardly grinder impulse of the spring 36, and the firing pin 28 will contact and oxolode the cartridge alined with the opening 12. An expansion spring 410 encircles the shaft 36 and bears at its forward end against a collar 41 carried by or aflixed to the said shaft, and seats at its rear end against the collar 42 loosely inclosing and independent of the shaft, the said collar 12 being held stationary by conventional brackets indicated at 100. The spring thus normally forces the shaft forwardly to position the latch- 37 in the path of travel of the notched portion of the lever 27 A tilting bracket 413 is associated with the arms 39 for retracting the shaft 36, and comprises bars crossed in the manner shown. This bracket lies close to the arms 39, and is adapted to have its bar ends or lateral extensions 39 engage the arms 39 when tilted, to force the member 39 rearwardly to withdraw the latch shaft against the tension of the spring 40. Secured to the bracket 43 and projecting forwardly therefrom is a lever 46, which is pivoted intermediate its ends as at 48 to a yoke or block 47, the latter being mounted for oscillation upon pins 4:7 extending from the ends thereof and supported by a post- 7 5, (Fig. 5). This arrangement is such that tilting of the bracket in right angular directions may be made, the

block being capable of oscillating in a direction at right angles to the direction of movement of the lever 46.

Piroted as at 45' to the forward end of the lever a6, is the inner end of a trigger rod 1 1. This rod is mounted for sliding movement inwardly and outwardly of the casing A in a block 15, the latter having laterally extending arms a6 ournaled at their ends in suitable bearings 77, and being capable of oscillating vertically within the casing. The block 45 is also provided with a vertically disposed slot as indicated by dotted lines in Fig. 2, so that the rod 14 may move horizontally within the said block. A coil. spring v 18 encircles the trigger rod as shown, and bears at its forward end agamst a collar -19 fixed to the rod, and at its opposite end against the'block 45. The rear end of the trigger rod extends through the opening 50,

the ends of the horizontally disposed bars 'of the tiltable bracket will operate to force the arms 39 upwardly, and the latch 30 will be withdrawn. Should the trigger rod be moved laterally, the same will rock upon the arms 46, and the lever 46 will oscillate in a similar direction, whereupon the vertically disposed bracket arms will operate 'upon the similarly disposed shaft arms to .move the shaft rearwardly, (see Fig.

Upon releasing the trigger rod the springs 40 and 48 will operate to force the parts to normal position.

In order to hold the member 44 in a central position in the opening 50 through which it projectsa spring 51 is provided which has one'end in connection with the member 44' and the other end connected with a bracket 52 carried by the wall of i the compartment 1.

The-short arm of the bell crank lever ha pivoted theretoyat 53"an angular lever 54 the end ofwhich extends through an opening 55 in the head end ofthe compartment 1, and engages with the lugs 11 carried by the cartridge chamber 9. The endof this angular lever 54 is provided witha pawl 55 which acts, whenthe lever 27 is actuated, to move the cartridge chamber 9 in one direction continuously in a step by step movement; the cartridge chamber being latched in said position by a latch 56 carried in lugs 57 and held in an inward position in engagement with lugs 11 by meansof a spring 58, said latch 56 havingan inclined surface 57 which is engaged by the lugs 11 to let the latter by-pass in one direction and to prevent the same from moving in a backwardly direction. The co operation of the pawl 55 and latch 56 holds the cartridge chamber 9 in a set position. The angular arm 54 is held in its normal position by means of the spring 59 mounted at 60 on the short arm of the bell crank lever and bearing against the angular arm 54. The exterior of the casing A is provided at 61 with a gimletscrew 62, which may be screwed into the floor or the like to set the device in an operative position. Also the exterior of the casing A is provided with brackets 63 which have pivoted thereto at 64 the legs 65 which are nothing more than segments of a circle and there 7 in dotted lines in Fig. 1 to insure the legs against catching when the device is placed .in the pocket for carrying the same.

The device is particularly adapted for use by commercial travelers or the like who have occasion to occupy rooms as transients and are subject a great many times to theft. The device in its operation is either screwed or set on the floor adjacent the floor of the room with the end 66 of the trigger operat ing element 44 in such a position that if the door is moved the member 66 will be engaged and in that way the device actuated. It will be seen, that by reason of the conslruction of the trigger operating mechanism, it is sensitive to the slightest movement and though it is only just touched the device will be operative.

In resetting the device the member 34 is pulled upward which raises the bell crank lever 27 into set position whence it is engaged by the latch 37. This also actuates the angular arm 54 so thatit moves the cartridge chamber 9 around to bring another cartridge into position.

lVhen reloading the device it is only necessary to uncatch the latch 16 by pressure on the button 24 whence the member 14 may be swung outwardly carrying with it the cartridge chamber 9 which may be then rotated suitably to reload the same with cartridges.

' While in the foregoing and in the drawings I have illustrated a specific cmbodimentof the" present invention it is nevertheless tobe clearly understood that this embodiment is illustrated merely for the purpose of explaining. the principles of the device and Ido not limit myself to such embodiment except in so far as the invened when tilted to engage said arms to move 7 the samo'and said latch to retracted pos1- tion, a trigger rod mounted for sliding and oscillatory movement, and a connection be tween said rod and said bracket.
