Abstract
ABSTRACT OF THE DISCLOSURE
A release device for deadfall traps of the type having a load line for supporting a deadfall in a raised position, the device having a load line engaging arm swingably mounted on a body which is maintained in an engaging posi-tion by engagement with a movable detent member the latter being held in a set position by a movable trigger. When the trigger is moved out of engagement with the detent member, the detent members swings away from the arm and allows the latter to swing to the release position to thereby release the load line and allow the deadfall to drop.

The release mechanism 10 has a U-shaped body member 15 having a pair of parallel arms 16-16 and U-shaped base 17, the arms having free ends lg-lg.
A load line engaging member 21 is mounted on a pin 22 extending between the arms 16 adjacent their ends lg for swinging movement. The member 21 is L-shaped having load line engaging arm 23 which is adapted to receive a loop .

The tongue 25 is adapted to engage and extend over one end 26 of an elongated detent member 27 which is mounted intermediate its end for free swing;ng movement on ~ transverse pin 2~. The opposite end 27 of the detent which has a substantially shar~ configuration is adapted to be releasably enga~ed by a trigger 31.
The trigger 31 which is pivotly mounted on a transverse 1~ pin 32 extending between the arms 16-16 has an elongated lever portion 33 and a hooked head portion 34. The lever portion is pro~ided with a plurality of holes 35 through any one of which the trigger line 13 can be threaded. Alternatively, as shown in broken outline in Fig. 1, a trigger extension 36 such as a length of wood can be bound by cord to the lever portion and the trigger line secured to the free end of the extension. The hooked head portion 34 is adapted to extend over the end 27 of the detent as shown in Fig. 1 The load line restraining member 21 is normally held in --a set position as shown in Fig. 1, by means of a locking pin 37 which can be extended through holes 3~-3~ formed in the arm 16.

: 10~461 The release mechanism is capable of wide adjust-ment relative to trigger line tension required for trap operation. If the trap is to be used for trapping small animals the trigger line can be secured near the end of the lever arm of the trigger or to the trigger extension so as to increase the lever advantage. Operating pressure can also be adjusted by adjustment of meeting surfaces of the trigger and detent. These surfaces can be arranged to provide either positive or friction lock of the trigger and the detent to suit trigger line tension for the type of animal for which the trap is set.
