4Letters Patent-No. 109.664, dated November 29, 1870.
IMPRovizMi-:NT IN WATER-WHEELS.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Beit known that I, DEMMON REYNoLDs, of Napanock, in the county of Ulster and State of New York, have invented certain Improvements in WaterJVhecls; following is a full, clear, and exact description thereof, reference being had to the annexed drawing making part of this specilication, in whichv Figure l is a plan -view of the casing of a turbineH water-wheel.
Figure 2 is a horizontal section on line a: :ccf tig; 3.
Figure 3 is an axial section.
The same letters are employed in all thelignresin the designation of identical parts.
rlhis invention relates to turbine.water-wheels; andl My improvements consist in the construction of the gates, and in their combination vwith other parts of the wheel, as will be more specifically set forth in the i'ollowing description and claim.
The wheel (not shown in the annexed drawing, as it forms no part of this inventioniis to be inclosed in a easing` formed by a crown-plate, A, and a yhorizontal flange, B', ot' the discharge-tube with intermediate ports and gates.
The said crownplate is sn'ppprted upon and secured to the ange B1 by shouldered bolts B2 in the manner shown, andA is to be provided with a central aperture to forni a passage and bearing for the wheel-shaft.
The ports to direct the water upon the buckets of the wheel are formed by guide-plates O C, so arranged tha-t the water passing between them will strike -the buckets in a line about tangential to the peripheryot' the wheel. l
Each guide-plate has a iiange, C', curved backward around the opening fouthe wheel, the rear edge of such lian'ge being such distance from the guide-plate in rear of it as to leave a throat or port, for the passage of the water, of the proper size.
The ports are controlled by a series ot' gates, D, which I propose to make of a cylindrical form, as shown, and secure them to a concentric ring, E, fitted upon the crown-plate around a hub or shoulder thereon.
These cylindrical gates pass through elongated slots, d, in the crown-plate, down to the upper surface of' the iiange B, and are operated simultaneously in opening and closing the ports by means of' a pinion, F, meshing into a cogged segment, E', on the ring E.
Ihe power for operating the' gates is applied to the vertical spindle F1, upon which the pinion F is secured, and which rests in a step upon the crownplate, and
is further supported in a bridge, F", spanning the pinion, and bolted to said crown-plate.
The ring `E has a central hub, with an aperture neatly ttiug the hub of the crown-plate on which it turns, said ring being connected to its hubA bya series of radial arms, as shown.
In order to insure simultaneousuess in the closing of the ports by the' gates, I propose to secure the latter to their common ring E in the following manner: f
The .required number of holes vis bored in the ring for the recept-ion of the upper reduced end of the gates, the holes being madesomewhat larger than such portions of the gates.
Each gate having been passed through its ,slot in the crown-plate, and having beenmade to bear firmly against the guide-plates so as to close the ports, as shown in fig. 2, theyare firmly fixed in that position in any suitable manner.
-The ring is then slipped over them, their upper ends passing through the holes, which, being somewhat larger, will readily admit them even'though they be slightly out of the center.
Intothese holes, the bottom of which is formed by the shoulder on the gates, molten Babbitt metal is poured around the reduced ends ofthe gates, which, after the metal has set, are further secured by nuts, as shown, when the temporary fastenings ofthe gates are removed.
In operating the gates they slide along the back of' the anges C on the guide-plates, and it will be found 'that long use only enhances their effectiveness.
In some cases I propose to cover the gates by a cylinder, D, ot' India rubber, elasticity, will permit all the gates to be shut even though some beslightly out ot' position.
Having thus described my invention,
What I claim, and desire to secure by Letters Patent, is-
lhe combination of the crown-plate A, iiange B,
guide-plates O G', gates D, ring E E', and pinion F1, all constructed, arranged, and operated substantially as shown and described.
In' testimonpivber'eof, I have signed my name to the foregoingspecication in the presence of two subscribing witnesses.
DEMMON REYNOLDS.
