IMPROVEMENT 'IN TU RBINE WATER-WHEELS.

Specification forming part of Letters Patent No. 205,1/15, dated J une 18, 1878 application filed March 30, 1878.

To 'all lwhom fit may concern: I

Be it known that I, JOHN SoHUEssLER, of Attica, in the county of Fountain and State of Indiana, have invented a new and valuable Improvement in Water- Wheels; and I do hereby declare that the following is a full, clear, and exact description of the construc-` tion and operation of thesame, reference ybeing had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a vertical section of my water-wheel. Fig. 2 is a plan view, and Fig. 3 is a horizontal section, thereof. i

' The nature of my invention consists in theA construction and arrangement of a water-wheel, as will be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates my invention.

A represents the lower part of the casing, with the bridge-tree B formed in one piece. The part Alias an outwardly-proj ecting flange, a, around the top, with an offset, a', on the under side of said flange, to rest on the floor and keep the heads of the screw-bolts b oft' the the iioor, which screw-bolts connect the lian ge a to a similar flange, e, around the lower part of the port or chute casing C, thus holding said two casings firmly togethe The casing G is formed with sixteen ports or chutes, d, or more, according to the diameter of the wheel, which will give the water the ri ghtdirection to the wheel. The casing C is bored out on the inside, so that the wheel will revolve in it after being turned off, and so that it will leave the middle bridge between the ports or chutes above one-third of the width of said ports or chutes. The casing C is also turned off on the outside, so that the valves or gates D can be tted to it closely and form a water-tight joint. These valves or gates correspond in number to the number of chutes d, and each valve is, at top and bottom, provided with an ear, f, to form hinges, so that the valve can bel reversed, and used both for a right and left wheel. They are also hollow on the inside, in order to reduce friction, as shown at h, to receive pins z'. These pins i, as well as the pins z", which enter the ears e ofthe valve-s, nare fastened ,in a revolvin gring, E, which is formed with arms El and a central hub, E2, said hub being bored out to encircle the neck or pedestal F on top of the E, so that when rotated back and forth it willv have the required throw to move the gates far `enough to open and close the chutes d. The

ring is operated by a crank, Gr, which is held in a bearing at one end of an arm H, the

other end of which is bored out andv fits the neck F', and is held thereto by apset-screw, k, and a key, l. The arm H answers the double purpose ofholdin g the crank Gr in position, and

also to hold the'revolving ring E down on the casing F and on the valves or gates d'.

The crank G has a square hole in the upper end, and answers as a socket to receive the gate-rod or valve-rod I, by means of which the gates or valves are opened and closed, as

required. The crank has a collar, m, on its upper end, held by a set-screw, fn, so as to support the weight of the crank and rod. The lower end of the crank fits into a square box, J, with a round hole in it to t the lower end Yof the crank, and this box works in a groove `o`r grooved jaw cast on the revolving ring E,

so that whenthe crank is turned the boxJ will move' out and in the jaw K, and thus move the ring Eto open and close the valves.

The valves or gates D are held to their seat by the pressure of the water, and in addition I employ a springring, L, surrounding the entire series of valves vor gates, which will hold them in place when opened or closed without any pressure on them; and if therev should'be any` obstruction in any one or more of the ports or chutes of the casing C, this spring-ring-will1 allow such valve or valves to swing open on` its hinge, so as to slide over such obstructions, and by doing so the remainder ofthe valves or gates can be closed and the wheel stopped. On the upper end of the neck F is secured the bearing or follower box M, by means of a set-screw, p.` In this box are wooden followers r r, which are tightened to the wheel-shaft by set-screws s s. On the top of the box M is bolted a cover or head, N, which is formed with an upwardly-proj ectin g hub, said hub being turned at the top, as shown at x, to form a joint withametal collar, O. This collar is bored out to fit the wheel-shaft, and counterbore'd in the under side to receive a wooden collar, P, which is turned to fit the hub of the head N. The collar O, filled with wood P, will keep all sand, gravel, or mud out of the box M, thereby preventing the cutting of the wheelshaft. The collar O will revolve with the wheelshaft, and its own weight will keep it down on the hub of the head N.

The wheel consists, principally, of an upper rim, R, a series of buckets, R1,`and an exterior band, R2, around the lower ends of thel buckets.` These buckets are straight from the upper rim R down to the band R2, and lean far enough ahead so as to form a right angle when they are placed even with the middle bridge between the ports or chutes d. The buckets are curved and flaring down to, the lower end of the band R2. The curved part ofthe bucket runs back past the straight line of thebucket behind it, so as to give it a downward backward discharge. A g e l l The bandft2 is cast solid to the buckets, and forms at the top lan inward flange, t, toward the straight parts of the buckets, which will make a joint to the lower end of the port or chute 'casing G. The wheel also opens on the lower part of the inside ofthe buckets, so as togive it a variable discharge, Whichis effected by means of a movable ring, R3, operated by adjusting-screws o c..y These screws are worced through hand-holes w w in the top casing F, which holes are covered by plates y y, held by suitable serew bolts. The wheel can be Iturned so as to bring the adjustingscrews u to correspond with the hand-holes w, and then they ycan be worked with a suitable wrench, so as to raise and lower the movable ring R3, as required. By raising the ring R3 more power, and by lowering said ring it will discharge less water and decrease the power.

After thelmovable ring R3 has been set so as to givethe required power, the adjustingscrews o lvare kept from working loose by means of straps or keepers bf, lwhich'have oblong holes in one end to` receive screw-bolts d. In the other end'of each keeper is a squarev hole, to t over the square ends e of the adjusting-screws f1; and rest on the shoulder or collar of the same, so that when the screwbolts d' are loosened thejkeepers can be turned oft' froml the adjusting-screws, and when said s'cre'w's'ha've been ladjusted the keepers can be slid up against the square ends e', and then fastened by the screw-bolts d', andy thus prevent the adjusting-serew v from turning.

- S is the wheel-shaft, which is fastened to the wheel by a key, and runs on a wooden step, h', placed in the center of the bridge-tree B, which step can be set up by a set-screw, f', through the bottom of said bridge-tree. The shaft S runs up through the follower-box M and collars O P far enough to receive a coupling for suitable shafting.

By means 'of the band R2 on the wheel all the water is kept on the wheel until it leaves the wheel, and therefore keeps all the friction from the lower casing; and, being larger below the ports or chutes d, it will discharge the water full and give it a greater velocity or speed.

What I claim as new, and desire to secure by Letters Patent, is-

l. A water-wheel consisting of the rim It, series of buckets Rl, and exterior bottom band R2, the buckets being straight from the rim to the top of the band, and then inclined,V as 'described, and the band provided at the top with the Iinterior iange t, all substantially as and for the purposes herein set forth.

2. A water-wheel provided with an interior adjustable bandto make a variable discharge, as herein set forth.

3. In combination vwithla water-wheel, the interior adjustable band R3, adjusting-screws t, andthe casing F, with band-holes fw and covering-plates y, all substantially as and for the purposes herein set forth. Y
