Abstract
Abstract A nonlethal self-protective device utilizing pressurized cans of an incapacitating fluid and a gaseous fluid. The device includes a nozzle for dispensing the incapacitating fluid and a whistle which is activated by the gaseous fluid. The contents of the cans are released by the actuation of a trigger which in turn actuates a camming member which moves a valve actuator to depress the valve stems of the cans.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
247 words
A protection device comprising a housing, means in said housing for mounting a container of a pressurized protective fluid, means in said housing for mounting a container of pressurized gaseous fluid, a first member having ports for the reception of the nozzles of said containers, means mounting said first member in said housing for movement in a direction parallel to the axes of the containers and preventing movement in a direction perpendicular thereto, a second member having a cam surface, means mounting said second member in said housing for movement in a direction perpendicular to the axes of the containers and preventing movement in a direction parallel to the axes of the containers, means on said first member for engagement by said cam surface for moving said first member in a direction toward said containers when said second member is moved in a direction perpendicular to said containers, a trigger mechanism pivotably attached to said housing and in engagement with said second member to move said second member, a gas operated whistle mounted in said housing, said whistle including a gas inlet, a nozzle unit in said housing having an outlet communicating with the exterior of said housing and an inlet, first duct means connecting the port receiving the nozzle of the container of protective fluid to the inlet of said nozzle for providing a fluid passageway therebetween, and second duct means for connecting the other port to the whistle inlet for providing a fluid passageway therebetween.
Claim 2
Dependent Claim
247 words
A protection device comprising a housing, means in said housing for mounting a container of a pressurized protective fluid, means in said housing for mounting a container of pressurized gaseous fluid, a first member having ports for the reception of the nozzles of said containers, means mounting said first member in said housing for movement in a direction parallel to the axes of the containers and preventing movement in a direction perpendicular thereto, a second member having a cam surface, means mounting said second member in said housing for movement in a direction perpendicular to the axes of the containers and preventing movement in a direction parallel to the axes of the containers, means on said first member for engagement by said cam surface for moving said first member in a direction toward said containers when said second member is moved in a direction perpendicular to said containers, a trigger mechanism pivotably attached to said housing and in engagement with said second member to move said second member, a gas operated whistle mounted in said housing, said whistle including a gas inlet, a nozzle unit in said housing having an outlet communicating with the exterior of said housing and an inlet, first duct means connecting the port receiving the nozzle of the container of protective fluid to the inlet of said nozzle for providing a fluid passageway therebetween, and second duct means for connecting the other port to the whistle inlet for providing a fluid passageway therebetween.
Claim 3
Dependent Claim
38 words
The protective device of claim 1, further including safety means movable between an ''''on'''' position and an ''''off'''' position for preventing movement of said members when the safety is in the ''''off'''' position and said trigger is pressed.
Claim 4
Dependent Claim
105 words
The protective device of claim 2, wherein said safety means includes a safety button mounted for movement in said housing, a safety latch, means mounting said safety latch in said housing for movement in a direction parallel to the axes of said containers and constraining it from movement in a direction perpendicular thereto, means interconnecting said latch and button so that upon movement of said button to the ''''on'''' position said safety latch is moved toward said containers in a direction parallel to the axes thereof, and means on said latch for abutting said safety latch when said safety button is in the ''''on'''' position.
