Abstract

A cash drawer burglary alarm system wherein the removal from a cash drawer of a bill of currency lying between a plate with an opening therein and a switch biased to extend through the opening will cause an alarm to be actuated.

Claims

1. An alarm system comprising a transmitter, means to actuate said transmitter, said transmitter actuating means comprising a plate with an opening therein, a switch, a portion of said switch being positioned so as to extend through said opening, means for selectively actuating said transmitter when said portion of said switch extends through said opening and for deactivating said transmitter when said portion of said switch is prevented from extending through said opening, said opening being a size such that a bill of currency placed between said portion of said switch and said opening in said plate will prevent said portion of said switch from extending through said opening and thereby prevent said transmitter from being actuated.

2. An alarm system comprising a cash drawer, said cash drawer having a bottom wall with an aperture therein, a plate, said plate defining an opening and being coupled to said bottom wall in overlying relation thereto with said aperture and said opening being aligned, a switch, said switch being coupled to said bottom wall below said cash drawer, said switch having a portion movable between a first position where it extends through said opening and a second position where it is disposed on one side of said plate, means for biasing said switch portion through said opening, an energizeable alarm, means for energizing said alarm when said switch portion extends through said opening and deenergizing said alarm when said switch portion is on said one side, and said opening is of a size such that a bill of currency disposed between said switch portion and said opening will retain said switch portion on said one side so that said alarm is normally deenergized.

3. An alarm system comprising a plate, said plate defining an opening, a switch, said switch comprising a plunger, biasing means for moving said plunger in an upward direction, said switch being disposed on one side of said plate and having a switch portion movable between a first position where it extends through said opening and a second position where it is on one side of said plate, said switch portion including an elongated arm having one end coupled to said switch, an intermediate portion in engagement with said plunger and its other end biased to extend through said opening, an energizeable alarm, means for energizing said alarm when said other end extends through said opening and deenergizing said alarm when said other end is on said one side, said opening being of a size such that a bill of currency disposed between said other end and said opening will retain said switch portion on said one side so that said alarm is normally deenergized, and said alarm is energized when said other end of said elongated arm is urged through said opening by said plunger.
