Abstract: 25 April, 2018 (See illustration & stages of MOTION) 1) The supports are positioned on either side of the trough. These provide the supporting platform(s) that the top axle rests upon. Bearings allow this axle to rotate freely in a circular motion. 2) Arms (one on either side) are connected to the top axle. A weight may protrude from the opposite direction of the swing arms to counterbalance the swinging motion. 3) Bottom axle is attached to the distal ends of the swing arms. 4) Circular displacement cylinder with a diameter of approximately 4.5 meters and a preformed hollow internal diameter connects to the bottom axle by having the axle pass through the internal center hole thereby receiving its support and movement through that axle. Bearings located between the internal central hole and resting on the outside of the axle allow the circular displacement mass to spin freely upon the axle thereby allowing it to spin freely in a circular motion itself, as it impacts and travels in a circular arc through the water. Motion The single illustration (Motion) illustrates four separate periods of movement, which indicates the motion and direction of the swing arms, the displacement mass and the resultant wave. The action consists of the swing arms and displacement mass traversing a full 360 degrees in one relative rotation motion with the arms and displacement cylinder moving in the direction that the wave is intended to travel and generating the wave. This action should NOT be considered as a pendulum effect and at no time is the arms and displacement mass expected to reverse its direction or swing back and forth. fAlso, in my provisional patent application, my use of angles of degrees were not accurate as defined by textbook physics, and there is change to angle definitions relative to the vertical and horizontal planes. There is NO change or alteration whatsoever to the actual idea, action, Page 1 of 3 25 April, 2018 mechanism or its range of motion between the provisional lodgement and this lodgement}. To aid in understanding of the range of motion: Flat level ground is defined as o or 180 degrees. Vertical is defined as 90 degrees. PHASE A - o / 18o Degrees (bottom) to 90 degrees (top / vertical) Electric torque motor(s) connect to the top axle via spline cog and gearing. This motor or motors will provide power for initial movement. (Similar to other semi and full range pendulum rides but different in action) The wave generating action begins with electro mechanical energy input (motor(s) plus counterbalance weight) This force rotates the top axle which raises the attached swing arms and displacement cylinder mass from o / 180 degrees (bottom / resting/ flat ground), through to 90 degrees (top / vertical height). PHASE B - 90 plus 1 Degrees (top / vertical) falling via gravity to o /180 degrees (flat / bottom) After reaching 90 plus 1 degrees, the arms plus connected displacement mass fall via impetus and gravity from 90 degrees top to o / 18o degrees (bottom resting) in a continuation of the same direction of the Phase A raising. Before reaching this bottom resting position it will impact the water in the trough. (I cannot provide an exact angle in degrees of this impact but estimate it to be at the 4 o'clock hour position if compared to an analogue watch face). It is anticipated that this impact energy will cause substantial water displacement which will convert of its own accord through natural laws, into a shaped volume of water (wave) and travel down the trough towards the main wave pool body.
