Abstract
This machine operates solely by the force of gravity acting on it. It consists of a set of weight wheels which, when acted upon by gravity, cause a driven wheel to rotate. The rotation of the driven wheel is brought about by the continuous varying in length of the lever arms, centres of weight wheels to centre of the driven wheel. A particular feature of this motor is that the variations in length of the lever arms occur even though the weight wheels are travelling a circular path at all times. The beneficial consequence of this method of working is that there is no reduction of the energy output of the motor caused by repeated variations in the lines of travel of the weight wheels, while wear of the moving parts and vibration of the motor are both reduced.
Description
Title. A gravity-activated motor.
Background. An urgent search is taking place in an attempt to find alternative sources of energy, (i.e. Green' energy). By harnessing the force of gravity, in a workable form, the long term problems facing our planet could be largely overcome.
Statement of Invention. The motor which is the subject of this patent application is a machine which is made to operate solely by the force of gravity acting on it. It is in two main parts, a suitably supported wheel and a set of weights. By the force of gravity acting upon the weights, the wheel is made to rotate. The rotating wheel is then capable of performing useful work.
Advantages.
It will operate continuously, at a constant speed, anywhere on the planet.
None of the earth's resources need to be extracted in order for it to function.
Because no gases are given off, no damage to the ozone layer will occur while it is operating.
It is relatively inexpensive to manufacture.
It will be totally reliable, and will require little maintenance.
It will be long lasting, with few of its components eventually requiring replacing.
It can be offered in various sizes, offering energy outputs to suit different situations.
Further to the last above, its configuration permits any number of motors to be coupled together on a common output shaft.
It is not limited to the generation of electricity for domestic and industrial purposes. In the smaller versions it will offer an alternative to internal combustion engines for the charging of the battery packs in electrically operated hybrid motor vehicles.
Also, It would benefit any other situation that might require a constantly revolving wheel.
As an example, water supply and irrigation in the Third World countries; when coupled with an Archimedes screw pump, the raising of water from wells and water courses.
(See reliability and little maintenance' above.)
Detailed Description.
When reading the following, please refer also to Drawings on Pages 1 to 14 attached.
First, a brief explanation of what is depicted on each of the drawings: Page 1/14, Figures 1, 2 and 3. The basic principle. A development of the see-saw.
Rotary motion of the beam can be made to commence. But this will not be continuous.
Page 2/14, Figures 1 and 2. However, if the weights can be made to move closer to, or further from the fulcrum, while working together and at the correct points in the cycle, continous rotation of the beam will occur. To achieve this, first replace the beam with a wheel (the driven wheel), suitably supported. Please note the radial slots.
Page 3/14, Figure 1. To have heavy weights constantly moving closer to and further from the centre of rotation, while rotation is occurring, is unsatisfactory.
Therefore, contrive a means by which the weights will travel a truly circular path, yet while still causing the driven wheel to rotate.
Page 3/14, Figure 2. First replace the weights by weight wheels.
Page 4/14, Figure 1. A typical weight wheel, the weighting material totally enclosed.
Page 4/14, Figure 2. Next, install on the base plate, adjacent to the driven wheel, a vertical, truly circular, annular track as a guide for the weight wheels.
Page 5/14, Figure 1. Modify one end of each weight wheel shaft by the addition of a slider mechanism, in two parts to permit installation into the driven wheel radial slots.
Page 5/14, Figure 2. Showing the weight wheels located against the running surface of the annular track and the slider mechanisms inserted into the driven wheel radial slots.
Page 6/14, Figure 1. Indicating the problem of cantilever supporting of the weight wheels.
Page 6/14, Figure 2. To obviate the above problem, add a second annular track and another set of weight wheels.
Page 7/14, Figure 1. With the configuration so far described and illustrated, there will not yet be any rotation of the driven wheel.
Page 7/14, Figure 2. But with a repositioning of the annular tracks such that the centre of travel of the weight wheels is no longer concentric with the driven wheel, rotation of the driven wheel will commence.
Page 8/14, Figures 1 and 2. Showing how, In a static situation, or until a critical speed of rotation is achieved, the upper weight wheels will tend to move lower in their radial slots. And the way the problem can be overcome by the addition of two hubs'.
Page 9/14, Figure 1. But as described above, the weight wheels will be continually changing their direction of spin. This is considered to be unacceptable.
Page 9/14, Figure 2. Therefore, reposition the two hubs outside the annular tracks.
Extend the weight wheel shafts at each side and add additional weight wheels.
Page 10/14, Figures 1 and 2. Indicating the way the weight wheels now operate on the hubs and annular tracks, riding on the hubs and annular tracks over half their travel and idling over the other half.
Please return now to Page 9/14, Figure 2. It will be observed that during the upper half of their travel, each weight wheel shaft is supported only by the outer weight wheels riding on the hubs, while during the lower half of their travel, by the inner weight wheels riding on the annular tracks.
Page 11/14, Figures 1 and 2. Showing first the suggested construction of the weight wheel shafts, then the modification to the driven wheel radial slots to accomodate the slider mechanisms when manufactured in one piece.
Page 12/14, Figures 1 and 2. The final configuration of the mechanism readily lends itself to the coupling together, on a common driven wheel (or output) shaft, of any number of motors. Attach to the end (or both ends) of the output shaft a chain sprocket, V belt pulley or gear wheel to enable transmission of the drive to the dynamo (or other).
Page 13/14, Figures 1, 2, 3 and 4. Lubrication. The final configuration also lends itself to a simple lubrication system, comprising oil delivery by means of perforated scoops attached to the perimeter of the driven wheel, with oil receivers located to serve the slider mechanisms, the weight wheel bearings and the driven wheel bearings.
Page 14/14, Figure 1. Maintaining the oil level inside the sump will be critical, but this can be easily achieved by means of a float valve, inside a compartment to eliminate rippling, with a combined external filler tube and oil level indicator.
Detailed Description (Contd.)
Throughout the descriptions and illustrations so far offered, four weight wheels and four driven wheel radial slots have been depicted for the purpose of explanation. But a greater number, depending on the diameter of the driven wheel, will sometimes be beneficial.
Wheel shaft details. The driven wheel to be securely attached to its shaft to permit the drive to be transmitted. But the weight wheels to be free-spinning on their shafts.
Weight wheel shafts. Note the spacing of the weight wheels by means of shoulders' on the shafts, together with spacer tubes and end plate fixing.
The weight wheels. To prevent deformation of the weight material (lead or other) caused by centrifugal forces, encase the material within the weight wheel and add an end plate with a separator tube attached. (All as illustrated).
Throughout the earlier descriptions, further weight wheels have sometimes been added in order to overcome a problem. Each addition of more weight wheels has increased the efficiency and power output of the machine.
Power output variables: Diameter of the driven wheel. Number of weight wheels.
Mass of each weight wheel. Number of motors coupled and acting together to drive a common output shaft.
Important detail. The repositioning of the annular tracks, (and so, the weight wheels), causing the centre of rotation of the weight wheels to be eccentric as against the centre of the driven wheel, (resulting in lever arms of varying length), is the key to the functioning of this type of gravity-activated motor.
Supports. The driven wheel shaft supports and the hub supports can be combined.
This will require apertures to be formed in the hubs to permit entry of the driven shaft.
Lubrication. It is anticipated that this type of motor will be relatively slow running, with very little heat generated. Consequently, the system earlier described, together with the oil mist that will be present inside the casing, will provide adequate lubrication.
However, the layout of the perforations to the oil scoops will need to be planned, in order that the various oil receiving points receive their supply as the scoops revolve.
Note also that the oil receivers to the weight wheels are located on the weight wheel shafts, and not on the weight wheels, where speed of rotation would be excessive for adequate lubrication to take place.
Control of rotational speed. This will require the matching of the motor's torque against the drag' of the driven dynamo (or other driven mechanism). Within certain limits, any slight variation required could be achieved by the raising or lowering of the oil level in the sump, causing the oil drag to increase or reduce. But in some situations it might prove necessary to install on the output shaft a suitable mechanism, perhaps an air brake, centifugally controlled.
The static situation. During manufacture and at times when repairs and renewals need to be carried out, because the natural state of this machine is to be constantly rotating, it will also be necessary to install on the output shaft a locking device. This would need to be coupled with a system of braking, perhaps a simple band brake, or alternatively, a magnetic brake powered by self-generated electricity.
Finally, construction material envisaged. Any or all of the following: Cast iron. Wrought iron. Steel. Lead. Alloy. Unplasticised (hard) plastic.

- 8. The configuration of the moving parts of this motor lends itself to the coupling together on a common output shaft of any number of individual motors, so adding to the variable energy outputs available by increasing or decreasing the size of the driven wheel and the size and mass of the weight wheels.
- 9. The configuration of the moving parts of this motor also offers a means of lubrication of the moving parts by utilizing the rotation of the driven wheel to distribute the lubricating oil.Amended Claims have been filed as follows 1' Claims 1.
