Abstract
Abstract A durable rodent baiting device which is safe for use around children, domestic animals and wildlife. A substantially rectangular box is provided with upright side and end walls. The end walls have openings therein to permit the rodents to enter the interior of the box. A plurality of baffle members, disposed parallel with the end walls, extend upwardly to the top of the box and across the full width of the box. The outermost baffles, nearest the end walls, have openings therein which are offset from the openings in their associated end walls so as to prevent children or the like from gaining access to further interior portions of the box. A divider between adjacent baffle members defines at least one receptacle for the rodent bait. A cover and means for securing the cover to the box are also provided to prevent unauthorized tampering.

Claim 1
Independent Claim
206 words
A rodent baiting device comprising: a substantially rectangular box having upright side and end walls, said end walls each having openings therein adjacent to a common first side of the box to permit rodents to enter the interior of the box; a plurality of baffle members disposed parallel to the end walls and extending across the entire width of the box and the full height of the box, the outermost baffles nearest the end walls having openings therein spaced from the top and bottom of the box, disposed adjacent to a common second side of the box, opposite to said first side so as to prevent children or the like from gaining access to the section of the box between the outermost baffles; at least one divider extending the full height of the box between adjacent baffle members for providing at least one rodent feeding station located between the openings in the end walls of the box and an entry section located between said openings in the baffles and accessible to rodents only therethrough, said divider having a central opening connecting the feeding station to the entry section; a cover for the box; and means for securing the cover to the box to prevent unauthorized tampering.
Claim 2
Dependent Claim
206 words
A rodent baiting device comprising: a substantially rectangular box having upright side and end walls, said end walls each having openings therein adjacent to a common first side of the box to permit rodents to enter the interior of the box; a plurality of baffle members disposed parallel to the end walls and extending across the entire width of the box and the full height of the box, the outermost baffles nearest the end walls having openings therein spaced from the top and bottom of the box, disposed adjacent to a common second side of the box, opposite to said first side so as to prevent children or the like from gaining access to the section of the box between the outermost baffles; at least one divider extending the full height of the box between adjacent baffle members for providing at least one rodent feeding station located between the openings in the end walls of the box and an entry section located between said openings in the baffles and accessible to rodents only therethrough, said divider having a central opening connecting the feeding station to the entry section; a cover for the box; and means for securing the cover to the box to prevent unauthorized tampering.
Claim 3
Dependent Claim
113 words
The device of claim 1 which further comprises: first, second, third, and fourth baffle members; said plurality of baffle members including a first divider extending perpendicularly to the end walls and joining said first and second baffle members thereby forming a first bait feeding station; a second divider extending perpendicularly to the end walls and joining said third and fourth baffle members thereby forming a second rodent feeding station; openings in said second and third baffle members to provide entrance ways into said first and second rodent feeding stations; and said second and third baffle members including further openings therein forming a passageway whereby the rodent can enter either of said feeding stations.
Claim 4
Dependent Claim
54 words
The device of claim 2 which further includes a lip extending perpendicularly to the end walls and joining said second and third baffle members to form a trac for receipt of poison powder whereby the rodent must travel in the trac on its way to and from said first or second bait feeding stations.
Claim 5
Dependent Claim
12 words
The device of claim 3 wherein it is constructed entirely of metal.
Claim 6
Dependent Claim

The device of claim 1 wherein said feeding station further comprises: a plurality of substantially inclined parallel plates forming a shute into which rodent poison can be readily placed, with one of the plates including an opening therein out of which said poison is fed by gravity.
Claim 11
Dependent Claim
16 words
The device of claim 9 wherein said one plate terminates below the top of the box.
