To all whom t may concern:

Be it known that I, THOREY I. Monia, a citizen of the United States, residing `at Chippewa Falls, in the county of Chippewa andState of Wisconsin, have invented certain new and useful Improvements in A.nimal-Traps, of which the following is4 a specification. i

The primary object of this invention 1s to provide a device for entrapping rodents, and similar animals, into a receptacle by means 0f automatically setting trap doors so arranged that the springing of said doors does not take place until the rodent has advanced over one *and onto another of the same, the latter door being operab-ly connected to a trigger, normally maintaining the first mentioned door in inoperative position, so that upon contact of the rodent with the secondpmentioned door said rodent is suddenly precipitated into the receptacleby the simultaneous yielding of said doors. It is contemplated to employ a guard member associated with the second door and beneath which the bait is disposed, for the purpose of preventing the escape of the rodent by leaping in the direction of its movement onto the doors, when it first feels yielding of the same under its weight. These and such other objects as may hereinafter appearare attained by the novel construction, combination and arrangement of parts to be hereinafter specifically described and claimed.

Reference will now be .had to the accompanying drawings forming a part of this specification, wherein# n Figure l is a perspective View of an embodiment of this invention. Fig. 2 is a longitudinal sectional view through the device. Fig. 3 is a horizontal sectional view on Ythe line 3-43 of Fig. 2 looking in the direction of the arrows. Fig. 4 isa vertical sectional view on the line 4;-4' of Fig. 2.A Fig. 5 isa vertical sectional view on the line 5`5 of.V

Fig. 2. Fig. 6 is a sectional View on the line 646 of Fig. 5, and Fig. 7 is a sectional `view on the line 7 7 of Fig. 4 showing `more clearly the pivotalmounting of a door employed in this trap. Throughout thefollowing detail description, and on the several igures'of the drawings, similar parts are referred to` by llke reference characters;

Referring to the drawings and specifically describing the invention, the numeral l designates a receptacle, the material of which is preferably metal, said receptacle being provided with a' pair of coperating trap doors 2 and 3 pivotally mounted in an opening in its upper surface as at 2, 3'." As a matter of convenience a gangway 4 is secured to the receptacle at one end so as to enable the rodent to be entrapped to gain access to the upper surface of the receptacle l. It will be noted particularly that the mechanism for controlling the operation of the trap doors of this device is disposed within the receptacle and for the purpose of presenting a device in which the moving pa-rts are not likely 'to arouse the suspicion of a rodent as to the nature of the same. This mechanism will now be described.

Near the forward end of the receptacle l of the trapis provided a partition 5 eX- tending transversely of the receptacle and having aV vertical slot 5 therein in which is pivotally mounted a trigger 6, the trigger being of a weighted variety so as to automatically cause this element to assume a normal upright position such as is shown in Figs. 2 and 6. `The upper end of the trigger is notched and normally engages over a spring loop member 7 pendent from one end of the door 2. Pivotally vsecured 'to a wall of the partition 5 is a double arm operating lever 8, one arm 8 of which is secured to the upper end of the trigger 6 as shown at 8". The other arm '8L of the lever 8 extends or is bent downwardly from the main portion of said lever and is connected by means of a link or bar 9 to the pendent arm l0 of a second double arm lever l0 Vpivotally mounted beneath the trap door 3. The second arm l()a of the lever l0 extends forwardly of the door and contacts therewith as shown most clearly in Figs. 2 and This dooris also provided at its rear end with a pendent loop l1 the purpose of which will more clearly be set forth hereinafter.

Withthe above details of construction in mind the operation of the device will be apparent from the following: The bait for the trap is preferably disposed at the rear end of the receptacle I'adjacent the rear end of thetrapdor 3 and -beneath =a guard member or `cage l2 which is disposed upon the upper surface of the receptacle in a position surrounding this door.` When the rodent passes up the gangway 4 onto the surface of the receptacle and advances ontothe door 2 toward thebait at the farther end of said receptacle said door is preventedAfro/m yielding by reason of the engagementof the trigger 6 with the pendent loop 7 carried by thedoor 2. Immediately upon the contact of the rodent with the door 3, the rodents weight will cause the door to yield downwardly at its free end which actuates the lever 10 and through the connection 9 eluded.V For this purpose the circuitwires c V13 and 14 leading from a source ofelectrical energy such as a battery (not shown) are connected to the doors- 3 and 2 respec-V tively, as most clearly shown in Figs. 2 and 3, the circuit being maintained open by reason of the spacing of the free ends of V said doors from each other, or if desired said doors'may be suitably insulated from eachother in amanner well'known to those skilled in this art. To enable the transmission of the electric current the doors are understood'to be of metallic material so that whenthe rodent, standing upon the door 2 moves onto the door 3 thecircuit is closed and the electrocution takes place as he is precipitated into the receptacle. The partition 5 is preferably'provided adjacent its upper edge with an inwardly projecting arm 15 which by its engagement with the spring loop member 7 Ylimits the pivotal Y Y movement of the door 2 as shown in dotted lines of Fig. 2; Likewise the door 3 is limited in its movement by the provision of a projecting abutment arm lf3-extending from the partition 17 in said receptacle through Y, the cooperation of said armrwith the spring i loop 11. Y v As hereinbefore mentioned, the lower end of the trigger Gis weighted or made heavy Y' in its formation so as to automatically return to its upright position when the doors have been sprung and the weight of the rodent isremovedtherefrom. This trigger, therefore, acts to forcibly cause the door `3 to assume itsr originalfhorizontal position.'

VThedoorm?J is weighted .at its outer edge as 'n shown at 1S so thatwhenthe weight of the animal is taken from said door it will descend at this` end and the loop "which is of a yielding character will engage beneath the hooked terminal of the trigger. It will 'be apparent that the spring 7 performs aj dual function in that it maintainsthe door in normal horizontal position by its coperation with the trigger `6 as above described and also acts to limit the pivotal `movement of said door through its coperation with the abutment arm 15. Itsometimes occurs that the rodent upon the initialyielding of Y trap doors in devices ofA this character effects its escape by leaping therefrom and to guard against this possibility I have emyployedfthe guard screen 12 surrounding the door 3, Vwhich guard also prevents access to the bait without approaching same over the trap doors. .j
