IMPROVEMENT 1N WATEafwHEE-ts.

TO ALL WHOMIT MAY CONCERN Be it known that I, JAMES D. BRYSON, oi' Newcastle, in the countynf Lawrence, and State of Pennsylvania,

have invented a new Vand useful Improvement in Turbine Water-Wheels; and Ido herebyideclarethe following to be a full, clear, and exact description ofthe nature, construction,4 and'operation of the same, reference being had to the-accompanying drawing, making part of this specification. I

i [ms invention consists, rst, in'novel means for adjusting the buckets to correspond with the adjustment vof the gates, in order that 4such relation may beV maintained between the two, as to position or angle, as will insure the most effective operation under the variationsiin the amount of acting water, which are due to the adjustment ofthe gates or inlet; second, in the employment of slotted arms, through the medium of which the gates are opened simultaneously and permitted to close independently, in order that obstruction 'to the motion of one or more buckets s hall not interfere with the operation of the remainder.

Figure 1 is a horizontal section of a turbine-wheel and its accessories illustrating my invention.

Figure 2 is a sectional elevation of the same, the section being made on a verticali plane coincident with the axis of rotation. v

Figure 3 is a side elevation, and

Figure 4 is a detached view illustrating the mode ofadjusting the gates.`

Similar letters of reference indicate corresponding parts in the several figures.

A may represent the framing, in which'theturbine B, with its spindle C, may be mounted to rotatein customary manner. The buckets B form oblique abutments, against which lthe water from the external casing is permitted to impinge in order to impart rotation to the wheel B, upon which the said buckets have pivotal attachl ment. The amountof water 'allowed tc act upon the buckets B in a given time is regulated by the gates D, which are attached by pivots to the stationaryv castings E E. The waterexcrts a simultaneous action upon the buckets 4I3 all around the periphery of B, and passing between the buckets it descends through the central discharge space G, iig. 2. The gates D are opened or closed to enlarge or diminishthe inlet spaces between them, `by the rotation of the annulus H, (see figs. and 3,) which is connected with thegates D by means 0f thearms I, and which is operated by means of the cogged segmentJF and the pinion K on the shaft K1, thc

latter being turned by means ot'rthe wheel K2, 'lhe inner extremities of'the arms Ine-refsuitably jointed to the l annulus H, while the outer ends of said arms are formed with slots i, which reccivethe pins cl, whereiy tho arms are connected to the gates. When the annulus His turned so as to project the arms I beyond the'periphery of E, the gates D are opened simultaneously, and the inlet spaces enlarged in consequence of the direct action of said arms upon the pins d, but when the arms I are retracted by a reverse motion of the annulus H the slots Ir adapt the gates D to be closed, thereby diminishing the inlet spaces by the pessure of the water in the suxrounding casing, each gate having freedom to close-independently of the others. Hence any objectwhi'ch muy obstruct one or two of the gates will not interfere with the desired adjustment of the remainder. In` order to secure the greatest powerwith a given amount of acting water, I have found it requisite to change the position ofthe buckets B as often as the gates D undergo a' new adjustment, thereby maintaining that relative position of the buckets and gates which insures t'he most effective ilnpingement of the water. This adjustment of the buckets I eiect by the means which I shall now proceed to describe. L L represents a twopart staff or rod, toaccommodate which the turbine-spindle C is made hollow, as shown in iig's. 1 and 2. The spindle C is also slotted at c, to permit the vertical play of a rod, l, which attaches a vertically adjustable collar, M, to the lower. extremities of L L. N N N represent a series of radial arms suitably pivoted at their opposite extremities to the collar M and buckets B. Thcupper end of L is threaded` and furnished with ajam-nut, o, which, being turned'by means of a hand-wheel, 0.', to which it is keyed, serves to raise or lower the stati` L L', together with the collar M. The collar M acting through the arms N serves to open or close the buckets, as the case may be, in order to vary their position tocorrespond with the gateSpD. A swivel-joint at Z adapts the upper part of the staff L to move the lower part L vertically without imparting its rotating motion thereto. M

Having thus described my invention, what 1 claim as new therein, and desire -to secure by Letters Patent,isp-+f-` 1. The combination. in a turbine water-wheel, of the adjustable gates or chutes D, and adjustable buckets or issues B', whereby the area. of the issues] may be varied to correspond with the regulated capacity of the inlets or chutes.

2. In combination with the above the slotted adjustingu'ms I I, appliedso :ts to open the gatessimultzmeously and permit them to close independently,v so :is to preventthe obstruction of one or more gates from inter fering with the operation ofthe remainder. v

3. The combinzition, with the adjustable buokets B', of the adjusting-stall' o1' serewL L', and swivel Z', applied vand oper-ating substantially as described. l

4. The combination of the staff or screw L L', and swivel Z', hollow slotted spindle E, jointed arm-s N, and ring-or collar-VM, arranged as flesribed, and operating so as to perf-nil; the buekets to be adjusted while tli'e wheel is in motion, 'as set forth.
