Specification of Letters Patent. l ajfi gg ted A g gg 1g22 Application filed March'7, 1921. Serial No. 450,330.
T0 aZZ whom/it may concern:
Be it known that I, STUART OTTO JoHNs, subject of the King of Great Britain, residing at The Parade, Island Bay, Wellington, New Zealand, have invented a new and useful Improved Construction of Rotary F an or Turbine Wheel, of which the following is a specification.
This invention relates to any of the usual types of rotary fans or turbine wheels used in certain classes of water supply apparatus to automatically control the passage of water through the apparatus, or in various known types of fluid meters, and in other like devices, in which the fan wheel orv turbine is caused to rotate by the action offluid pressure upon its curved blades or vanes.
These wheels hitherto, have not been 0011- structed to provide for the correct adjustment of the action of the fluid pressure thereon to obtain accuracy of action in the recording means or other apparatus with which the wheel is combined and which it actuates in such appliances.
The present invention has been devised with the object of providing a construction of wheel in which provision is made for the accurate adjustment of its rate of rotation in relation to the fluid pressure actuating it and by which such rate may be reduced to any desired extent from the maximum.
The invention consists in so constructing the wheel that the surfaces of its vanes or blades upon which the pressure acts may be broken in their continuity, and outlets for such pressure formed between the breaks, which by variation in their widths, will increase or diminish the pressure force thereon according as the outlets are decreased. or increased.
The invention may be carried out in different ways according to the particular type of wheel with which it is employed. Grenerally however, it is effected by dividing each of the blades or vanes into two parts, at about midway in its length, and in them so mounting the respective portions that they may be moved relatively to one another, with respect to the plane of their surface, and then fixed at any position such as to provide the break in the pressure receiving surface.
In the accompanying drawings the application of the invention to a w eel or fan of ordinary common type having the blades or vanes radiating in curves from a central boss, is shown. These drawings are however to be taken only as illustrating the principle embodied in the invention and the manner in which it may be given effect to.
In such drawings F gure 1 is a plan of the wheel, and
Figure 2 a sectional elevation thereof.
The wheel shown in the drawings is of the type commonly employed in fluid meters and like appliances, and is constructed with its blades or vanes A curving radially outward from the central boss B and fixed to a frame plate or disc C extending over the bottoms of the said blades or vanes.
ln applying the present invention to such a form of wheel, each blade or vane A is divided into two at a point about midway in its length. The outer halves of the sev eral blades or vanes are fixed to the disc plate C while the inner halves are fixed to an annular plate D let into a recess formed in the surface of such disc plate so as to make a flush surface therewith. This plate D is made in one with a sleeve E fitting round the boss B and adapted to be rotated thereon. Its turning on the boss will therefore cause the inner portions of the blades or vanes to move relatively to their respective outer portions.
This inner part of the wheel may therefore be arranged to cause the two halves of each blade to form a continuous surface to receive the working turned to cause a break in such surface having a gap between the edges of the break. Such break and gap may also be regulated to any desired extent. Consequently the rate of rotation of the wheel. under given pressure may be accurately adjusted to any desired extent by regulating the break in the surfaces of the blades or vanes.
The inner portion of the wheel is designed to be locked from movement at any point to which it may be turned. The means shown in the drawings for obtaining this object consist in a washer plate F ada ted to fit over the top end of the sleeve and a screw G passing loosely through such washer and screwed into the boss B so that when screwed down, it will tighten the washer on to the sleeve and hold it from movement on the boss.
It will be readily understood that the same system of construction and. operation may be equally as well applied to fluid prespressure, or it may be sure actuated turbine wheels or fans of all descriptions, in order to obtain the same effect.
I claim 1. A fluid pressure actuated turbine Wheel or fan, characterized by having its vanes or blades each made with its length divided into two portions relatively adjustable with respect to the planes of their pressure receiving surfaces, substantially as and for the purposes herein specified.
2. fluid pressure actuated turbine wheel or fan, constructed with each vane niade in two parts 8XtGIlCllng end to end and with the respectively outer parts of the several Y vanes adjustable relatively to the inner parts thereof, so as to form breaks of variable extent in the pressure receivingsurfaces of the several vanes, substantially asand for the purposes herein specified.
In testimony whereof, I afiix my signature.
STUART OTTO JOHNS.
