FFICE.
JOHN KINCAID, OF VANCOUVER, BRITISH COLUMBIA, CANADA.
IMPACT WATER-WHEEL.
Application filed January 2-4, 1911.
To all whom "it may concern:
Be it known that I, JOHN KINoAn), citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Impact Water-Wheel, of which the following is a specification.
This invention relates to an impact water wheel of that class which is exemplified by the Pelton wheel, and my improvements are directed to the provision of a cup of such form that instead of dividing the jet and spreading it laterally from the plane of rotation, it will deliver it from one side or the other of the wheel and in reversing its direction of movement will divert it inward in opposition to the centrifugal force. By this means a greater proportion of energy of the water will be derived from it, in the further attainment of which object the inside of the cup is provided with a series of shallow flutes against the sides of which the water will react during the lateral diversion.
The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied, in which:
Figure 1 is a side elevation of a segment of the wheel showing one of the cups in outside elevation and the other in section on the plane B in Fig. 2, Fig. 2 is a plan of a cup, and Fig. 3, a transverse section of the cup on the line A.
In plan the outline of the cup is somewhat kidney-shaped the jet 2 delivering into the end 3 in or parallel to the plane of rotation, and at an angle approximately tangential to the path of this portion of the cup. Toward the other side 4, from which the water is delivered, the outline of the cup is turned slightly inward toward the axis of rotation of the wheel, and in the turn leaves somewhat of a spur or shoulder at 5 where it turns around the rim of the wheel or disk 6 to which the cups are secured.
The rim of the cup is substantially in one plane, save for a short distance at 7 where it cuts into the jet, where the cutting edge or lip of the cup is thinned to a fine edge and dips below the general plane of the edge.
In securing the cups to the wheel or disk the plane of the rim of each cup is angled slightly upward from planes radial to the axis of rotation. Thus the jet as it strikes on the side 3 will be delivered laterally to- Specification of Letters Patent.

ward 1 and in that movement will be thrown outward from the axis of rotation by centrifugal force. This tendency is, in a measure, counteracted by the general form of the outer edge 8 which bends inward toward the axis of rotation and being cup-shaped the reaction of this diverted jet absorbs the energy of the water while reversing its direction. This reacting effort is increased by a series of sharp edged ridges 9 which follow the general conformation of the outer edge 8 of the cup and deliver the spread water of the jet inward toward the axis of rotation of the wheel.
As shown in Fig. 3, the curvature of the cup transversely is more concave at the side 3 of reception of the jet and is flattened slightly toward the side 4: of delivery.
Where the ridges 9 spring from the side 3 of the cup they turn slightly inward, as shown in plan in Fig. 2, before following the transverse curve.
Vhat I regard as the essential features of the invention are the delivery of the jet on one side 3 of the cup and the conformation of the cup by which the impacting water is delivered toward the other side and inward toward the axis of rotation; and on the spur form 5 which deflects a portion of the spread jet outward against the inside of the ridges 9 and of the outer edge of the cup at 8, and in the provision of the ridges 9 curving transversely inward toward the axis of rotation.
The cups may be secured to the wheel in any suitable manner and in any degree of proximity to one another and may deliver to either side of the wheel in any one wheel, or in alternate cups, so as to balance any lateral vibration that may be set up in the wheel disk.
Having now particularly described my invention and the manner of its use, I hereby declare that what I claim as new and desire to be protected in by Letters Patent, is:
1. In an impact water wheel, a cup for the reception of the water jet the side of which cup into which the jet is received is more concave than the side from which it is delivered the general conformation of the cup in plan curving inward toward the axis of rotation at the delivery side.
2. In an impact water wheel, a cup for the reception of the water jet the outer edge of the cup 111 plan curving across the plane of rotation and inward toward the axis of the wheel and a series of sharp edged ridges in the bottom of the cup following generally the same inward curve.
3. In an impact water wheel, a cup for the reception of the water jet the side of which I cup into which the jet is received being ap proximately a spherical se ment and thereafter in plan curving inward around the edge of the wheel to which the cups are secured toward the axis of rotation, and a series of cup into which the jet is received is more concave than that to which it is delivered the plane of the rim being angled upward from a plane through the axis of rotation and the edge which contacts with the jet being lowered below the plane of the general edges of the cup.
5. In an impact water wheel, a cup for the reception of the water jet having ridges arranged transversely of the plane of rotation of the Wheel and curved inwardly toward the axis of rotation at one side.
6. In an impact water wheel, a cup for the reception of the water jet having ridges extending laterally from the position of impact of the jet toward the delivery edges of the cup and curved inwardly toward the axis of rotation at one side.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN KINCAID.
