Description

M. GREGG. TURBINE WATER WHEEL.
No. 92,603. Patented July 13, 1869.
33mm attire.
MAHL ON' GREGG, OF ROCHESTER, NEW YORK.
Letters Patent No. 92,603, dated July 13, 1869.
IMPROVEMENT IN TURBINE WATER-WHEELS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, Manson GREGG, of the city of Rochester, in the State of New York, have invented a new and useful \Vater-Wheel; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this specification, in which Figure 1 is a side elevation.
Figure 2 is an inverted view.
Figure 3 is a detached section, showing the shape of the bucket of the wheel 0, and a portion of gates B and E.
Figure 4 is a vertical section of the step-box The nature of this invention will be understood from the drawings and specifications.
To enable others skilled in the art to make and use my invention, I will describe its construction and operation.
The outside shell A, figs. 1 and 2, is made in the usual form of this class of water-wheels.
The gate B,'figs. 1, 2, and 3, which regulates the water as it passes into the .wheel 0, is a hollow cylinder, and fitted between the shell A and wheell so that it willmove around and vertically.
The lower edgeof this gate B is made in the form of three inclined planes, as shown in figs. 1 and 2, or it may be made in-the form of two, or morethan three inclined planes, each one forming the section of the thread of a screw.
On the outside and lower edge of these inclined planes a flange is formed, which fits into a slot in the end of the arms a, figs. 1 and 2.
As the gate B is turned around, the flange on the inclined planes passing through the slots causes the gate to move vertically, thereby regulating the opening of the entrance-ports of the wheel 0, and when the gate B is raised to its -full extent,' closing the entrance-ports.
In the edge of the fltngeof one of theseinclined planes, at screw-gear, figs. 1 and 2, is cut to receive the thread of screw 1), figs. 1 and 2, which being turned causes the gate B to move around.
The screw D is carried by the shaft a, figs. 1 and 2, one end of which is sustained by arm a, the other end by any suitable means.
A hollow cylindrical gate, E, figs. 1, 2, and 3, is also placed on the inside of the wheel (J, which is constructed and operated in the same manner as the gate B, only the flanges of the inclined planes of this gate E operate in slots in standards F, figs. 1 and 2, which are bolted to the step-frame G.
The object of this gate E is to regulate the size of the issue-ports of the water-wheel, by applying the gate immediately to them, so that when the water is low the amount of issue can be regulated in proportion to the entrance, and a larger percent-ago of power can be obtained than when the water is regulated at the entrance only.
The upper and lower shell of the wheel 0 is inclined downward, fig. 3, from the skirt of the wheel to' the issue of the buckets. This gives a downward inclination to the buckets and causes the water to leave the wheel in a downward direction, and renders it less liable to choke around the centre than if the water was discharged directly toward the centre of the wheel.
The step-box J, figs. 2 and 4, of this wheel, is sustained by the frame G, which is bolted to the outside shell A, and is formed of three or more bridge-trees joined on to a ring, y, in the centre, fig. 2.
On the inside of this ring y, there are lugs 22, on which the lugs of the step-box J rest.
The step-box is held in any desirable lateral adjust- .ment by set-screws.
By this arrangement, the step-box is also easily removed when requiring repairs, it being only necessary to turn the borearound until the lugs will pass the lugs of the ring, and it can be withdrawn.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. ,The gate E, applied directly to the exit-ports of a water-wheel, in combination with an inlet-gate, for the purpose set forth.
2. The gateB, having its edge formed in the shape.
