Abstract From the Canadian patent
A hydraulic or pneumatic shock-absorber for sporting and hunting bows is fitted, as a connecting element, between a stabilizing counterweight (spinner) and the bow in such a manner as to permit, between the counterweight and the bow, a movement which is damped in the direction of the shot, although the counterweight is secured rigidly to the bow vertically and horizontally to the direction of the shot. This leads to smoother launching of the arrow and to marked accuracy.
