Application filed January 6, 1921.

T 0 all whom it may concern Be it known that 1, WILLIAM H. Goon, a citizen of the United States of America, residing at Toledo, Lucas county, Ohio, have invented new and useful Detonating Alarms, of which the following is a specification.

This invention relates to detonating alarms.

This invention has utility when incorporated in protective or burglar alarms for windows, doors, etc.

Referring to the drawings:

Figure 1 is a perspective view, with parts broken away, showing an embodiment of the device mounted in position as to a door;

Fig. 2 is a side elevation of the device of Fig. 1 showing the device or alarm in setposition, carried by a bracket secured to a sash, so that the window may be open for ventilation, but further opening will cause the alarm to be tripped;

.Fig. 3 is a view of the device with the detonator holder in section, showing the device in tripped position and mounted on the cross sash of a two part window;

Fig. 4 is a perspective view of the base;

Fig. 5 is a view on the line V-V in Fig. 2 looking in the direction of the arrow and having the detonator carrier shown in dotted lines;

Fig. 6 is a perspective view of the bracket,

7 which is shown carrying the device in Fig.

2; and

Fig. 7 is a perspective view of the control arm of the device.

A door 1 is shown mounted so as to swing into opening or frame 2 which carries screws 3, 4, with their heads slightly clear of the frame 2. For the screw 3 is provided end notch 5 and for the screw 4. a side notch 6 in base member 7 of the alarm device. A

portion 8 of the alarm device is somewhat raised from the base 7 and has ears 9, 10, on the outer side inwardly extending to embrace the broad end of a spring member 11 shown as a flat or leaf spring with a widened rear end 12 which may be further anchored by rivet 13 to the raised portion 8 of the base member 7. The narrow or free end of the spring member or mounting 11 has therein an opening 14 through which protrudes a cylindrical member or holder 15 having a base flange 16 which may seat up against the underside of the member 11 when the holder 15 is in position. This holder 15,16, may be frictionally locked or riveted to the Specification of Letters Patent.

spring member 11. Concentrically with this holder 15 is cylindrical opening 17 therethrough having at its lower portion a peripheralannular countersunk portion 18.

Rising from the base member 7 below this holder 15 is an upwardly extending impact receiver 19 having a central or intermediate polnt 20 as the rim fire coacting means for a blank cartridge in the opening 17 of'the holder 15. Upstanding from the base member 7 adacent the impact receiver 19, 20, is arm 21, having in its lower portion a pivot bearing providing rivet 22 for a trigger member havmg a trigger ledge 23 and a tapered extension 24 therebeyond. This trigger member 23, 24, pivotally mounted on the bearing 22 1s carried adjacent upstanding portion 21 of the base member 7 and the ledge 23 coacts with the under side of the holder 15 against the resistance of the spring. 11, thus holding the device in a set position with a blank cartridge 25 in the seat 17, 18, held away from the impact receiver 19, 20.

Upstanding member 21 of the base 7 has near its top a second pivot bearing 26 carrymg a member having an upward channel portion 27 engaged on one side by the upward projection 24 of the trigger 28, 24. This channel portion 27 is part of a control member pivoted on the bearing 26 and having control extension or handle 28,

The trigger bearing rivet 22 has on the opposite side of the member 21 an annular flange or head 29 about which may be partially wrapped a (Ll-shaped spring having one leg 80 engaging the channel position 27 oppositely from the extension 24. The other leg 31 of this U-shaped spring 30, 31, enters opening 32 in the extension 24 of the trigger member 23, 24, to hold the trigger thrown toward the holder 15. 16. Accordingly the readily be installed or demounted by merely slipping the notches into position over projecting screw heads or other points for holding the device in position where it is desired to have the detonating alarm placed as in the instance of mounting on the door frame 2, or upon window sash 33. While the mounting or spring member 11 is quite rigid for a positive throwing of the detonator against the impact receiver, such may be lifted into raised position or set by a screw driver or other tool drawn upward in the region of the seat 15 to pull it up into such a position that the spring 30,. 31, will throw the trigger portion 23 out to hold the member so elevated. When thus normally set the control member has its arm 28 swung out- I ward or away from the member or base 7 In the event the one who sets the alarm desires to leave by the openin atwhich the alarm is set, this may occur, 101' the control member 28 may be swung toward the alarm device by a closing of an opening by a door or window without setting off the alarm. At once the part has passed the control member 28, it is again thrown outward by the spring member 30,31. However, should the closure for this opening be moved in the reverse direction or against the undersideof the control member 28, such movement will cause the channel portion 27 to act upon the extension 24 of the trigger member 23, 2 1, to draw the ledge 23 away from holding position as to the mounting member 11 and the holder 15 so that the spring 11 at once swings the cartridge 25 in'the holder 15 against the impact receiver 19, 20, and for rim fire this projection 20 will set 01f the percussion and the detonating discharge will result.

The device is conveniently mounted in any desired position as to the opening and may even be mounted in a position which would leave the seat downwardly open. In such last mentioned instances, to keep the cartridge 25 in the holder 15 from vibrating or shaking out, the cartridge 25 may be at its open end slightly squeezed or distorted so that it will frictionally engage in the seat 17 of the holder 15, 16. The device may be charged in its set position or may be conveniently removed by slipping it out of its notches and taking it down at such times as may be desired. Further if it is desired to leave the device in position all that is necessary to do is to throw the control member arm 28 into parallel relation with the upstanding arm portion 21 at which position the channel 27 rides to bring the spring arm 30 into seat 34: and the device is held inoperative and the trigger 23' is still protrudingand maintainsthe device set, but it is set not in-a position to be thrown oil by the control member for the control member open for ventilation, instead of mounting the device directly, it may be carried by a bracket 35 mounted by screws 36 on window stop 37 at the desired location for the member 28 to project into the path of travel of thesash 33. Lugs 38, 39, permit detachable mounting of the device to the bracket 35.

A detonating alarm of this disclosure is a substantial compact device of insured operation as to all of its mechanisms. It may not be distorted or readily disturbed when in operative position except as designed in its construction for such disturbances 'As it i made throughout of wrought metal parts, it is of the most substantial character. The sheet'metal base, trigger and control member are parts which are readily and e00 nomically stamped out and the'spring portion is also a substantial part not only oper V ating as a spring but also as amounting for 85 the holder. The holder is a tubular member which is readily formed to provide a seat as herein disclosed. The parts are such as might easily be produced in quantity and as so produced may be assembled into the devices of standard form with interchangeable parts for use in such diverse places as may be desired by the householder or for use in or about a place of business. While-the device is shown as a cartridge carrylng alarm of the detonating type and it is peculiarly designed for such utility, still the detonating features may be varied as found convenient in practice or to fit the conditions in which it is desired to be used. In those 100 instances where it is desired to mount the device some distance from the object, movement of which object is to set 011 the alarm device, in eye 10 may be engaged a wire or rod 11 extending to such object.
