Abstract: A gate locking mechanism includes an oarlock pivotally connected to an arm mounted upon a gate post to allow vertically displacement of the spaced apart arms of the oarlock, to and from captive relationship with a fence end post. The gate is secured in a closed position by passing a locking device through aligned openings in a lock tab on the oarlock and in a flange projecting from a lock collar mounted upon the fence end post. By mounting at least the lock collar in a manner to permit sliding and arcuate displacement about its post, the lock collar flange is shiftable to and from its cooperative relationship with the oarlock tab to provide a clear pathway when the gate is opened. In an alternate embodiment, the oarlock is substituted by another slidable and arcuately displaceable member having an apertured flange sliftable to allow insertion of a locking device through the flanges of both members mounted upon the two posts.

Abstract: An arrowhead has a flat face which is sharpened around the circular edge and a plurality of staggered blade units. Each blade unit contains two separate blades that are spaced apart down the length of the unit. The blade units are equally spaced about the periphery of the arrowhead. A profile from the front shows that the blades provide a continuous cutting surface in order to maximize bleeding in the target animal. The sharpened flat face is effective in punching a hole through the animal which the rest of the arrow shaft can follow through without frictional resistance.
