TURBINE WATER-WHEEL.

CPECEFZCATIQN forming part of Letters Patent No. 325,112, dated August 25,1885.

Application filed June 1, 1.885. (No model.)

,T0 @ZZ whom it may concern:

Be it known that l, Josemi lit-tain, of Dayton, in the county of Montgomery and State of Ohio, have invented certain new and usefulV Improvements in Turbine Vater-Vheels; and I do hereby declare that the following is a full, clear, and exact description o't' the invent-ion, which will enable others skilled in t-he art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters ot' reference marked thereon, which form part of this specification.

My invention relates to t urbino water-wheels, and especially to the means for cooling the lower bearing of the shaft or spindle of the wheel, and it consists in the construction, arrangement, and combination oi" parts, which will be fully described hereinafter, and afterward specifically pointed out in the claims.

Referring to the accompanying drawings, Figure l represents a side elevation ofthe apparatus, the stand or platform ol" which is partly in section, to show the connection ofthe pipe leading from a cage to the under part of the bridge-tree, where it lis formed integral with another pipe extending upwardly through an aperture formed in thc bridge-tree, and registering with a similar aperture formed `in the step. Fig. 2 is a sectional view of the frame, showing the normal position of the wheel or hub. Fig. 3 is a view in section showing more fully the construction of the mechanism .for cooling the shaft. Fig. l is a plan view ofthe ring which operates the gates, and Figs. 5, 6, and T are views in detail showing the various constructions of the ring.

Like letters of reference indicate like parts in all the iigures, in which- A represents a platform. Af vare circumferential l'langes, between which are formed a single series of partitions or walls, E, at equal distances apart and of the same thickness. These partitions are placed at the point where these partitions reach said circumference to the wheel or hub D, forming the casing or frame ot' my apparatus. C is a crown-plate, the under surface of which is iianged to rest on an annulus formed ou flange A. D is the packing-box', and a thethimble ia which works sha-ft It, all ot which have been described in the Letters Patent obtained by me prior to this application.

F are gates formed also at equal distances apart around and between the flanges A A. Said gates are hinged or pivoted at each end to the inner surfaces of the flanges, and in contiguity to the outer ends or edges ot partitions E, which are rounded to allow the gates to oscillate with perfect ease and quickness. The gates are of a peculiar construction, theirsides being slightly concave and the outer or foremost edges wedgeshaped. At their upper ends are formed wings or heads, the tops of which are provided with piutles s, as will be more fully described hereinafter.

To the sides of walls ll are attached packingstrips of rubber, leather, or other suitable material, to prevent leakage of the water when the gates are in a closed position.

Misa bridgetree fastened by bolts or screws to the inner periphery of the draitilume I), which forms a part of the lower iiange, A. c c are standards cast with the tree in a single piece, and d is a guide-plate for shaft lt.

D represents an inverted conoidal wheel or hub, having secured at regular distances apart on its periphery a single series of buckets set to form, substantially, continuations of the partitions Fi, so that water entering the ports would be caught regularly by the buckets and impart an even and regular motion to the wheel. rllhe said wheel or hub is provided at or near its top and bottom with circumfereir tial rims, the lower one projecting laterally from the hub to fit in the recess formed between the annular riln within the tlunie or penstock b. The hub, buckets, and rims, together with the shaft, are cast in one piece, but may be formed in separate pieces, it' pre ferred.

L designates a ring, which is provided with a number ot projections, i', to agree in number with the gates. To these projections are secured, by pint-les or screws. connecting-links n, provided at their outer ends with perforations which lit snugly on the pintles s, formed on the tops ot the gates. One of the pei-fora tions is larger than the rest, as it is used for the insertion of a screw,and not a pintle. Instead of theselinks 11,1 might use a somewhat different means for connecting the projections of the rings to the gates, as will be seen in Figs. 5 and 6. ln that of Fig. 5 the projections are formed with rectangular rectsses, in

IOO

which the piulles s are secured, and in Fig. (i :f

a different mode is used having elongated slots cut in its under surface,the inner or open end of which is slightly curved at an angle to the inner periphery of the ring. On the upper surface of the ring is secured by screws or bolts a serrated segment, m, parallel with the ring, in which meshes the pinion e, the shaft o of which has its bearing in an annular recess cut'in Bange A', as in Fig. 2. 'Ihe key tends to operate the ring L, which, having its con necting-link secured to the pintles s, operates the gates simultaneously.

K is a plate of metal designed to act as a cover for the starting mechanism, and has a boss, 7c, which forms a guide for shaft o.

G is a cage of any desired metal and shape, having a number of holes in its upper part for the straining of water, which enters and flows downwardly through pipef. Said pipe is divided into two sections, and is provided with a coupling, Z, which joins them together. The upper section is bulged at or near its top to form a valve-chamber, and extends above the bottom of said cage, whereby sediment is prevented from entering' the valve, but settles around it at the bottom. The pipe also forms a valve-seat, the valve itself being provided with an outwardly-hanging lip, which, when closed, forms a protection for its mouth. The top or crown plate of the valve has a small eye,into which is inserted a rod, z', for the purpose of lifting the valve, when desired, to allow the flow of water through pipe.

J is a thin strip of metal arranged to form' a guide and stop for the valve,aud prevents the accidental pulling out of the saine.

a is a support or collar, which ts snugly around the pipe, maintaining it in its normal position, and relieving the coupling of strain which it would otherwise have to bear.

t is a rod fastened to bell-crank w, pivoted to one side of a block, in which it has a bearing. The bell-crank has at one end a pintle, on which is secured a curved connecting-rod, T, the opposite end of which is attached to a valve, 7i, pivotally secured within the lower pipe, c, the purpose being to allow waste Water to pass out-,in case the pressure of water against the shaft be too strong, or in case of water remaining in the pipe after the operation of the wheel is suspended.

At or near the free end of the levert is placed a weight, y, (see Fig. 1,) which holds the lever down and maintains the valve in a vertical position, preventing leakage if the force of water against the shaft be not too great.

S is the step upon which revolves shaft R. This step is provided with an aperture extending through its whole length, which registers with pipe H, formed integral with pipe c, from which it receives its supply of cooling-water.

The operation of my invention will be obvious from the foregoing description. cooling-water, entering cage G through the perforations which serve as a strainer, is let run into the pipe c by the raising ofthe valve e, and thence through pipe H and step S to the shaft D, causing the same to rise suffi` ciently to allow water to pass between it and the step. If the pressure of the water be too great, the hand-lever t is slightly raised to open the stop-cock 7i, thereby allowing sufficient water to pass off, relieving the shaft of too much pressure.

Having described my inveution,\\'hatI claim 1sl. Thecage and pipe having a valve therein, a handle and connecting-rod pivotally secured to a bell-crank, and a valve, in combination with the step and shaft of a wheel, as hereinbefore described.

2. In a turbine water-wheel, the combination ofthe cage G and pipe f, which convey cooliug-liquid to the wheel, valve e, stop and guide J, support u, which holds said pipe iu a normal position, and step S,havingaconduit which registers with pipe H and the shaft of the wheel, substantially as described.

8. In a turbine water-wheel, the combination ofthe lever b, bell-crank w, and connecting-rod 'I with stop-cock 7i, pivotally secured within pipe f to allow the passage of water, when desired, in the manner hereiubefore set forth.

4. The combination, with a vertical shaft, of a water-wheel, the end or bearing of which beinghollowed out, and a step correspondingly rounded to fit said hollow, said step having a conduit passing entirely through it, whereby cooling-liquid is conveyed between the bearing-joint, for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature iu presence of two witnesses.

JOSEPH RAAB.
