ABSTRACT OF THE DISCLOSURE
An animal trap comprises a base member with two jaws pivotally connected thereto. Rings extend slidably about adjacent side members of the jaws and springs bias the rings away from the base member and towards end members of the jaws to move the jaws from a horizontal, open position to a vertical, closed position. A bell crank is pivotally connected to the base member and has an upwardly moveable portion where bait is secured. An elongate rod is pivotally connected to the bell crank at one end and engages one of the side members at a second end, when the jaws are horizontal, to maintain the trap in the open position. When an animal tugs on the bait, the rod disengages from the one side member and the trap closes to trap the head of the animal.

Description
Z
(~) BACI~ROUND OF T~E INVENTION
Field of the Inventlon This invention relates to a humane animal trap for trapping the head of the animal.
Prior_Art The public outcry in recent years against inhumane trapping methods and traps~ particularly the leghold trap, has led to a considerable demand for traps which will reduce the suffering o the animal.
One approach to the problem has been the development of traps adapted to close on the neck of the animal, resulting in a quick death by sufEoca~ion9 breakage of the neck or damage to vital organs. These traps normally employ a pair of jaws whLch are horizontal in the open position and have springs for biasing the jaws towards the vertical closed posi~ion, These jaws are large and noxmally can encompass the le~s and heads of the animals. One of the problems with ~hese types o traps, however, is that practLcally all of them can be released by a sideways motion of the ~ait holders which also act as triggers. Quite a number of animals normally first test the bait with . -: : , ' ': , ' .................................. . ' ~ ' ;

(3) their paws without putting their heads too close to the bait and when this occurs the trap can be sprung by sideways motion of the trigger and usually catches the leg of the animal rather than its head.
In order to prevent this type of occurren~e 30me prior art traps used wires which secure the bait to the triggers so as to obtain a release of the trap only when the wire LS tightened. However, this type of trap can be sprung i the animal strikes or pulls the wire with its leg or paw.

2~2 (5) DESCRIPTION OF Tl-E PRRFERRED EMBODIMENTS
Referring to the drawings, ~he animal trap l has a base member 3 comprising a strip of sheet metal with upturnsd ends 5 and 6. The base member 3 has an aperture 7 for receiving an anchor pin not comprising part of the invention.
Trap 1 has a pair oE jaws 9 and 11. Jaw g has two parallel side members 13 and 15 with distal ends 17 and 19, re~pectively, interconnected by end member 21. The ends 23 and 25 o~ members 9 and 11 proximal base member 3 are hook shaped and pro;ect through apertures 27 and 29 of thle base member 3 to pivotally connect jaw 9 to the base member. Jaw 11 is identical to jaw 9 with side members 12 and 14, an end member 16 and is pivotally connec~ed to base member 3 at apertures 31 and 33.
Trap 1 has a pair of upper rings 3S and 37 : which freely embrace ends 5 and 6 of the trap in the open position of the trap shown in Figure 1 and which extend slidably about adjacent side members o~ jaws 9 and 11 as the jaws move upwards towards the closed position of Figure 2, .
.
(6) Lower rings 39 and 41 extend about ends 5 and 6 oE base member 3 below upper rings 35 and 37 respec-tively. A coil spring member ~3 has an elongate extension 45 integrally connected -to upper ring 35 with another elongate extension 47 connec~ed to lower ring 39 and provldes means resiliently biasing ring 35 away frGm ba~e member 3 and towards the posi~ion agaln3t the end member~ 21 and 16 of the jaws 9 and 11, as seen in Figure 2. An identical coil spring member 49 similarly biases ring 37. Spring members 43 and 49, with rings 35 and 37, tend to move jaws 9 and 11 from the generally horizontal, open position, shown in Figure l, towards the generally vertical, closed posi-tion shown in Figure 2.
Trap 1 has a latch means for maintaining jaws 9 and 11 in the open position of Figure 1 which ?
: comprises an elongated rod ~1. The irst end 53 of ;~ rod 51, as seen in Figure 3, is pivotally connected to bell crallk 55, descrlbed below. The second end 57 of rod 51 projects slidably through aperture S9 on upwardly e~tending tab ~1 which is connected at its : lower end to base member 3. End 57 of rod 51 extends : over one slde member 14 of jaw ll and exerts a down-ward ~orce on ~aw ll and ring 37 to malntain the jaws in the open position~

~7) Trap 1 has a trigger means for releasing the jaws from the open position comprising the lever or bell crank 55 mentioned aboveO Lever 55 has a barbed hook 59 at a first end 60 and an aperture 6005 for se-curing bait to the trap, and is pivotally connected torod 51 near its second end 56. At its mid point 61, lever 55 is pi~otally connected to upwardly extending tab 63 of base member 3. Lever 55 has a horizontal portion 65 extending from Eirst end 59 to mid point 61 and a vertical portion 67 extending downwardly from mid point 61 to rod 51. Swinging of the lever is lim-ited by stops 66 and 67 extending from the tab 63.
In operation, the trap 1 is set by compressing spring members 43 and 49 downwardly from the closed position of Figure 2 until rings 35 and 37 extend about upturned ends 5 and 6 of base member 3. Hooks 69 and 71 can then be used to temporarily keep the spring members compressed as shown in solid lines in Figure lo ;20 The bait is secured to the hook or first end 60 of trigger means or lever 550 After the bait is secured, horizontal portion 65 of lever 55 is pushed downwardly and this moves latch means or rod 51 outwardly so its end 5~ projects over and engages side member 14 of jaw 11. As explained above, this will maintain the trap in the open position and hooks 69 and 71 can be .
.
.
' ~
(8) ~ ' released from sp:ring members 43 and 49 as seen in broken lines in Figure 1.
When an animal approaches the trap, it may test the bait and the trap with its paws. However, the trap will not be sprung by any sideways or down-wards ~orce on lever 55, but only by an upwards force.
The only ef~ective way that any common fur bearing animal can exert such an upwards force is by tugging on the bait secured to the hook at first end60 of lever 55 with its teeth. This pivots horizontal por-tion 65 of le~er 55 upwardly about mid position 61 and pulls rod 51 inwardly. When rod 51 is puLled inwardly, its end 57 slides through aperture 59 oftab 61 and disengages from side member 14 of jaw 11. Spring members 43 and 49 and rings 35 and 37 are then free to snap jaws 9 and 11 upwardl.y to the closed position of Figure 2. The size o~ the trap is selected for the animal being trapped so the neck of the animal is ca~ght ~e~ween jaws 9 and 11, resulting in a humane `~ death. Trap l cannot easily be sp~ung by the paw o~
the animal as can other traps designed to trap its head.
