Abstract

A fluid mill is provided with vertical shaft 10 with radially extending arms mounted on it. Bearing rods 12 are fitted to the arms. Vanes 13 are fitted over bearing rods and able to move as in Figure 4. During operation the vanes open and close under the action of the moving fluid in such a manner that the forces on each vane start from zero, build to a maximum and return to zero, hence no shock loadings. When the vanes are closed they oppose the flow of the moving fluid by presenting a large flat surface to it. When the vanes are open they cause little resistance to the moving fluid. <IMAGE>

Description

SPECIFICATION Fluid mill This invention relatesto a fluid mill for utilising the energy available ion a movingfluid.
Man has, since ancient times, tried to harness the power of wind,tide and river. For raising water, grinding corn and now, generating electricity. Many diferent designs of windmill have been used throug- houtthe ages. The horizontal axis machine requires to be mounted on a tall tower, and also needs to be pointed into the wind. A large component of the energy available being absorbed by the bearings, and only a small component, availablefor useful work.
Vertical axis machines have the advantage of being omnidirectional, but suffer from low output. Consider an anemometer, there is only a small difference between the cup on one side, catching the wind and the cup on the opposite side spilling it. Movable vanes have been tried, like the Panemone, but the vanes tend to snap closed and hence induce shock loadings.
Waterwheels require to be aligned in the direction of water flow.
Present fluid millstend to be overly complex, hence expensive. With high cost per unit output characteristics.
According to the present invention there is provided a fluid mill comprising a vertical shaft held in bearings and able to rotate. Mounted on top ofthis shaft arethree equi-spaced horizontal arms, having fourvertical bearing rods mounted on them. Vanes are fitted over the outerthree bearing rods on each arm. The vanes being so arranged that they are opened and closed by the moving fluid, in such a manner that the force on them starts from zero, rises to a maximum and returnstozero, over 180 degrees of revolution. During the remaining 180 degrees of revolution the vanes are opened by the moving fluid in such a manner that the vanes provide very little resistance to the moving fluid. Each of the arms are identical.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings, in which:- Figure 1 shows, in elevation, the vertical shaft held in bearings, the three arms, the vertical bearing rods; Figure2 shows, in plan, the three arms, the vertical bearing rods; Figure 3 shows, in elevation, and plan the vane; Figure 4shows how a vane is fitted over bearings rod and the vanes possible movement; Figure 5shows how all the vanes are fitted. This is a no fluid movement situation.
Figures 6, 7and 8 show direction of rotation, fluid movement direction twelve different arm positions for one complete revolution. Each position lettered in sequence from 'A' to 'L'.
Referring to Figures 1 ,2,3,4and 5 of the drawings, the fluid mill comprises a central vertical shaft 10 and arms 11 with bearing rods 12 mounted on them.
Vanes 13 are fitted over the bearing rods 12.
Referring to Figures 6,7 and 8 of the drawings, direction of rotation is shown by arrow 14. Direction of fluid movement is shown by arrow 15. Twelve different positions of arm, are shown lettered 'A' to 'L' in sequenceforone revolution offluid mill.
Position 'A' shows vanes having just closed under action of moving fluid. As fluid mill rotates, pressure on vanes builds up from zero, at position 'A', to a maximum at position 'D' and back to zero at position 'G'. Between positions 'G' to 'H' pressure builds up on opposite side ofvanes causing them to open out until in position shown in position 'H'. From position 'H' to 'A' vanes are open and cause very little resistanceto moving fluid. lnordertoensuresmoothopening and closing of the vanes an angled tail is provided on each vane as illustrated in the drawings.
1. Afluid mill comprising a rotating shaft, a plurality of horizontal arms extending radially from said shaft, each arm being provided with a number of bearing rods, vanes being provided on said bearing rods.
2. Afluid mill as claimed in Claim 1 ,wherein there are provided three identical equi-spaced arms each having four bearing rods, vanes being provided over the three outermost bearing rods.
3. Afluid mill as claimed in Claim 1 with fouror more horizontal arms.
4. Afluid mill as claimed in any preceding claim with five or more bearing rods with vanes to fit.
5. Afluid mill as claimed in any preceding claim with curved horizontal arms.
6. Afluid mill as claimed in any preceding Claim, wherein the arms are angled to the horizontal.
7. Afluid mill as claimed in any preceding Claim, wherein the vanes are straight.
