Description
'7~
Thi~ invention relates to animal traps and more particularly to a humane animal trap that will operate when the'animal is passing through the trap~
There have been many animal trap designs put forward in the past for catching differen-t types of animals in various ways. It has been considered that the type which is designed to strike the neck or back of the animal as distinguished from the jaw type for grasping and holding a leg of the animal~ is more humane. A well known type of trap in present use is the Conibear trap described in U.S.
Patent No. 3,010,245 issued November 28, 1961 to F.R. Conibear.
Other trap deslgns are described in the following United States Patents:

It is an object of -the pres~nt invention to provide a humane animal trap that will strike an animal passing through the trap on the back or the neck generally killing it instantly~
It is another object of the invention to provide an animal trap having a clampir~ means such as to hold the animal in the trap should it only be stunned on the initial striking action.
. This and other objects of the invention are achieved by an anlmal trap having an upstanding fra~e member mounted on a hase, a metal anvil bar connec-ted at one end to the frame and extending outwardly from the frame generally parallel to the base, a metal striker bar positioned above and generally parallel to the anvil bar, said bars being connected at their outer ends to a spring adapted to urge the striker bar forcibly towards the anvil bar, a trigger pan mounted below the two bars and connected to a trigger arm extending upwardly along the frame, a latch arm swivelly mounted on the upper portion of the frame and containing a notch or recess such that when the striker arm is moved upwards against the force of the spring away from the anvil bar, the arm fits into the notch, said latch having an extended arm contacting the upper end of said trigger bar such that when the trigger bar is in its upper position the latch arm is prevented from swinging holding the striker bar in the set position and when the trigger bar moves to a downward position on depression of the pan, the latch arm is free to swing allowing the striker bar to move towards the anvil bar, and clamping means for forcibly holding the striker bar down towards the anvil bar to provide a secondary killing action.
In drawings which illustrate embodiments of the invention, Figure l is a perspective view of the trap, Figure 2 is a cross-section of a variant form of the trap, Figure 3 is a a partial plan ~iew of the trap of figure 2, Figure 4 is a partial end view of the trap of figure 2, and L67~
Figure 5 is a top view of the tr~gger mechanism of the trap of figure 2.
Referring to figure l, the trap i5 I[lade up of a suitable base 10 on which is mounted a frame made up of two parallel positioned, L-shaped members lla and llb.
Fixed between these members by welding or other suitable means is an anvil bar 12a which extends outwardly parallel to the base and terminates in a single spring 13 formed by one or more coiled turns. The other end of the spring 13 extends inwardly, parallel to and abo~e the anvil bar 12a to form the striker bar 12b. This bar extends through frame members lla and llb and terminates in a T-bar 14 convenient for the user in setting the trap. The single spring has been designed to urge the striker bax down towards the anvil bar and stores sufficient energy to deliver a striking force of somewhere between 200 and 350 inch-pounds of energy. The spring is also designed to produce a clamping ~orce of about 20 pounds at a 1 inch opening posi-tion. A ratchet device made up of blade 15 and handle 16, spring loaded moun-ted on the striker bar 12b, is arxanged to catch into notches 17 cut into frame members lla and 11~. This device gives an additional resistance to prying open of the trap by the animal. Clamping and/or prying foxces are valuable features in humane trap design since they provide a secondary killing actian should the initial strike merely stun the animal.
The trap is set by ralsing striker bar 12b against the force of the spring by means of T-bar 14 untll it takes the position shown in dotted lines. The bar fits into a notch or detent 18 formed in trigger bar 19 rotatably mGunted in the fi~ed upper ends of frame members lla and llb.
3tl The trap is set off (triggered~ by an animal passing over the anvil bar throuyh the trap and depressing a trigger pan 20 rotatably mounted in the frame and positioned just below the 7~
anvil bar. Connected to the pan is a trigger bar 21 passing from the triyger pan through sleeves 21~ and 21b to -terminate adjacent the end of spring latch 19. When th~ trap is set the upper end o~ the trigger bar mechanis~ is in a position to prevent the spring latch from swinging sideways. When the trigger pan is depressed, the trigger bar moves downward until the end is free of latch 19 allowing the latter to swing to the side releasing the striker bar for down~lard striking action. A safety locking action is provided by pin 22 connected to the end of the frame which when positioned in opening 23 prevents inadvertant setting off of the trap.
Storage of the pin is provided by opening 24.
Figures 2, 3, and 4 show elevation, plan and an end ~iew of a variant form of the trap. The frame me~m.bers lla and llb are similar to figure 1 but at their bottom extend out into a base structure 26. The anvil bar 12a, striker bar 12b with T-bar handle 14, and spring 13 ~re similar to the figure 1 version but there is no ratchet mechanism on the striker bar. In this version the prying or cla~nping force is provided by an auxiliary spring 27 having ext2nded arms 27a and 27b, the irst of which is connected to a loop 28 encircling the spring and the second of which is connected to a la,rger loop 29 encircling the striker and anvil bars. Spring 27 is designed to urge loop 29 along the arms and when the trap is sprung, the loop takes up a position as shown in dotted lines to provide a clampiny force on the bars and thus the animal. The trigger mechanism again, co,mprises a triyger pan 20 which is connected to the spring through arm 20a and loop 20b and to triyger bar 21 passing through sleeves 2Ia and 2Ib and up throuyh an opening in spring latch 19~ The operation of the spring latch and triyger bar is readily shown in figure 5.
