IMPROVEMENT IN TURIBINE WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of the same.

v To all whom 'it may concern:

Be it known that I, JESSE NEWLIN, of tle'city and county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in' Turbine Water-Wheels, of which the following is a full, clear, and exact descriptioix, reference being had to the accompanying drawings, which make part of this specification, and inwhich- Figure l is avertical central section through myimproved turbine, f

Figure 2 is a diagram, showing myimproved method of adjusting the buckets of the wheel when arranged vertically relatively to the crown-plate; and

Figure 3, a similar diagram, with the buckets inclined to the crown-plate, and at right angles to the rim of the wheel.

My invention is equally adaptable to that class of turbines in which the water passes directly through the crowns of the wheel, (called parallel-flow turbincs,) or to that class in which thewater flows through the Wheel at right angles to this axis; and

The object of my invention is to adapt the wheel to the head of water, 4by increasing or diminishing the area of the issues; to which end,

The improvement herein claimed, consists in a novel lmethod of combining pivoted buckets with adjusting# devices, actuated by a rod moving endwise through the Y arbor of the turbine.

In the accompanying drawings- A -representsthe frame, which supports the stop B on which the arbor O revolves. That portion of the arbor above the bottomof the turbine is hollow.

A rod, D, passes down through they tubular arbor,

,and its lower end is slotted to receive cross-arms d,

which support a flanged plate, E.

Inclined loops or slotted brackets, projecting underneath this plate, reeeive`pins i, projecting from the buckets F F, which are pivoted to swing, as shown in v red in figs2 and 3, so as to vary the area of their discharge-orifices. v

It well known that with a supply or flow of water insufficient to fill the discliarging-area of thebuekets completely, turbines fail to develop their maximum perby my plan, the miller is enabled at all times to ad` just the escape of the water to the supply, and thus secure the full working-capacity of the turbine, its advantages are obvious.

The upper end of the arbor C turns in suitable bearings in the flame-work, while the lifting-rod -D terminates in a box, G, being provided with ahead or iiange,

d, to sustain it in the box, and yet allow it to revolve freely therein.

A screwed spindle, H, on the upper side of the box, is acted upon by a female screw, secured in a bandwheel, I, by which means the rod, and consequently the adjustillg-plate, may'ghe raised or lowered, andthe area of the issues correspondingly varied.

On the left side of iig. l, and in fig. 2, the buckets F are, as shown, pivoted to swing horizontally, while on the opposite side of fig. 1, andin iig. 3, the buckets F are shown as pivoted to play vertically.

In' the latter ease, the water enters the buckets di rectly through the crown of the wheel, and the flow is parallel to the axis, while in the former case, the How is from the circumference inward.

It is unnecessary to describe the details of construetion of the turbine, such details being well understood by skilful millwrights, and forming no part of the subject-matter herein claimed.

' What I claim my invention, and desire to secure by Letters Patent, is-

'Ihe combination, with the turbine, of the pivoted buckets, adjusting-plate and lifting-rod, substantially v
