Throwing traps, self-arrows, can be guarded both along and across the path. When guarding across the path, the speed of the victim must be taken into account, this method of guarding is good when hunting animals. They are elongated in the horizontal plane and represent a good target, for such self-arrows.
Throwing traps, self-arrows, principle of operation, possible installation locations, guard, masking.
It is preferable for a person to guard the crossbar along the trail, technically such a cross-guard is much more difficult, and it is rarely used like that. If the path turns, then throwing traps set on a bend, mask in vegetation above ground level. If the crossbow is on guard on a flat path, it is masked in a hole below ground level, with the expectation that the arrow at the place of installation of the gatehouse (stretch marks) falls into the upper chest of a person of medium height.
The classic crossbow is a large log with several notches. The largest is in front at the bottom for attaching the bow, it is often tied, although it holds itself with a taut bow, in front of the butt (log), but a small notch is made on top, a small wedge of the trigger mechanism rests on it (small chalak). One end of the blade is grabbed by a loop to the butt, the other abuts against the notch wall.
A lace is attached to the blade, which is connected to the long end of the lever (large chalak). This lever is attached to the back of the butt, its small shoulder holds the stretched bowstring. The large end of the lever can look both up and down. Instead of onions, you can use rubber tied to nails. If possible, a tube is attached to the front of the butt, into which the boom passes freely.
As a trigger mechanism, you can use modifications of most alert mechanisms. The main difference between them in the direction, along or across the butt. As self-arrows they use not only a bow on a pole, but also a variety of throwing traps, which are prototypes of throwing devices more primitive than a bow, spear throwers, slings, etc. Unmatched devices are also used..
Throwing traps using the energy of a falling body.
Among the latter are throwing traps using the energy of a falling body. Such mechanisms are ready to wait for a victim for a very long time, without loss of effectiveness. There were cases when self-arrows guarded in the ancient Egyptian pyramids were killed by poisoned arrows who wandered around the dungeons, and in our time.
In such constructions, the mass of the load and, consequently, the force of gravity can be very large, but the rate of fall of the load at the initial stage is very small, you can sag the rope so that the load has time to accelerate before it begins to act on the other parts of the propelling mechanism, and through them to the shell. Another way to increase projectile speed is to use leverage. Usually use both methods..
Sling Throwing Traps.
Throwing traps using the sling principle are represented by a large number of ancient stone-throwing tools with all possible simplifications. In the figure above, in the fourth diagram in the form of B1, a small notch, into which the rope enters, is not shown on the shaft. This notch is beyond the picture plane on the opposite side of the shaft shown..
The last two figures show the principle. Elements throwing a shell can be very different. In many designs of throwing traps, the projectile trajectory is highly non-linear and depends on many reasons, in such throwing devices it is necessary to carry out test shots during installation, with subsequent adjustment. The distance of destruction is usually not much greater than the length of the projectile.
