Abstract: A fluid dispensing anti-burglar device is disclosed which discharges a fluid, containing a chemical such as tear gas, into an area to be protected when an intruder opens a window or a door or forces open a window or a door to enter a private or unauthorized area with which the device is associated. The anti-burglar device employs a spring biased actuating member for discharging a pressurized container. A mechanical trigger for releasably retaining the actuating member in a cocked position and for releasing the actuating member to dispense the fluid, containing a chemical such as tear gas, is described. In addition, a lock mechanism to place the device in a non-triggerable condition is also shown.

Abstract: An anti-burglar sound emitting device is described in which a pressurized fluid is discharged to audibly oscillate a diaphragm to create a warning signal when an intruder opens a window or a door to enter an area unauthorized to the intruder. The anti-burglary device employs a spring biased actuating member for discharging a pressurized container wherein the fluid is discharged through a passageway and diaphragm valving structure. A mechanical trigger for releasably retaining the actuating member in a cocked position and for releasing the actuating member which moves the slideably mounted pressurized container to cause sound is described.

Abstract: A fluid dispensing anti-burglary device is disclosed in which a fluid, containing a chemical such as tear gas, is discharged into an area to be protected when an intruder forces entry into the area with which the device is associated. The anti-burglar device employs an electrothermal actuator as a trigger for releasing a spring biased member to cause the discharge of fluid from a pressurized container.

Abstract: A chemical dispensing anti-burglary device is disclosed in which a chemical such as tear gas is discharged into the area to be protected when an intruder opens a door or forces open a door to enter a private or unauthorized area with which the device is associated. The anti-burglary device employs a spring biased actuating member moving a pressurized container to discharge a chemical irritant. A mechanical trigger for releasably retaining the biased actuating member in cocked position and for triggering the device and a lock mechanism to place the device in a non-triggerable condition are described. A combination for using the device with a door locking bolt and bolt latch plate is also shown.

Abstract: An anti-burglary sound emitting device in which a pressurized fluid is discharged to audibly oscillate a diaphram to create a warning signal when an intruder opens a window or door to enter an area unauthorized to the intruder. The anti-burglary device employs a spring biased pressurized container for discharging a fluid through a passageway and diaphram valving structure. A mechanical trigger for releasably retaining a pressurized container in cocked position and for releasing the slidably mounted pressurized container to cause sound is described.
