Abstract
Abstract An alarm housing for a rodent control device such as a spring actuated trap. A frame with opposed side and end members defining a trap opening for receiving the trap, and an electrical switch mounted in the frame so that positioning of the trap in the frame moves the switch to one circuit condition. Tripping of the trap by a rodent produces a lifting action which moves the trap upward out of the frame permitting the electrical switch to move to the opposite circuit condition thereby providing an indication of actuation of the trap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
An alarm housing for a rodent control device, comprising in combination: a frame having means defining a trap opening in said frame for receiving a rodent trap; and an electrical switch mounted in said frame and having a switch actuating element movable between circuit open and circuit closed conditions, whereby a trap when positioned in said frame opening moves said switch actuating element to one of said circuit conditions, and tripping of the trap moves the trap out of said frame opening so that said switch actuating element may move to the other of said circuit conditions.
Claim 2
Dependent Claim
97 words
An alarm housing for a rodent control device, comprising in combination: a frame having means defining a trap opening in said frame for receiving a rodent trap; and an electrical switch mounted in said frame and having a switch actuating element movable between circuit open and circuit closed conditions, whereby a trap when positioned in said frame opening moves said switch actuating element to one of said circuit conditions, and tripping of the trap moves the trap out of said frame opening so that said switch actuating element may move to the other of said circuit conditions.
Claim 3
Dependent Claim
27 words
An alarm housing as defined in claim 1 wherein said frame has opposed side and end members with said electrical switch mounted in one of said members.
Claim 4
Dependent Claim
47 words
An alarm housing as defined in claim 2 wherein said switch actuating element is movable between extended and compressed positions, with said element normally in said extended position, and with a trap when positioned in said frame opening engaging said element moving it to said compressed position.
Claim 5
Dependent Claim
47 words
An alarm housing as defined in claim 1 wherein said switch actuating element is movable between extended and compressed positions, with said element normally in said extended position, and with a trap when positioned in said frame opening engaging said element moving it to said compressed position.

Claim 7
Dependent Claim
17 words
An alarm housing as defined in claim 4 wherein said electrical switch is a pressure type switch.
Claim 8
Dependent Claim
41 words
An alarm housing as defined in claim 1 wherein said frame comprises a unitary tray with a continuous periphery defined by opposed side and end members, and having a recess in one of said members with said electrical switch positioned therein.
