WATER ELEVATOR AND MOTOR.
SPECIFICATION forming part of Letters Patent No. 544,755, dated August 20, 1895.
Appli ati n fi February 1, 1895. Serial No. 537,015- (No model.)
City, in the county'of Ada, State of Idaho,
have invented a certain new and useful Improvement in Water Elevators and Motors,v
of which the following is a specification.
The object of my invention is to provide an automatic apparatus whereby the force of the current of a stream may be made available for raising water or driving machinery.
It consists of a series of propelling-blades having substantially plane surfaces, which are secured to endless traveling carriers at substantially right angles to the direction of travel thereof and are placed in a stream at an angle to the direction of the current thereof. By securing plane-surfaced blades on the one hand at right angles to the supporting-car; riers and, on the other hand, by placing the carriers and blades in the stream at an angle to the direction of the current thereof I secure certain peculiar advantages, which will be hereinafter referred to.
The best embodiment of my invention at present known to me is that shown in the drawings, in which-- Figure 1 is a perspective view of my invention. Fig. 2 is a plan View of a portion thereof. Figs. 3 and 4 are detail views of the propellerbucket, Fig. 3 being a section on the line 3 3 of Fig. 4, looking in the direction of the arrow. Fig. 5 is a perspective detail view of a modified construction, showing the use of a guide-rail by the side of the upstream-cable.
a or are endless cables passing over the sheaves b b, c c, and d d. Of these sheaves b b are suitably journaled on the upstream-support A, and c c and d d are journaled in up: right standards B, rising from the downstream-support C. These supports A and C are preferably boats suitably anchored and maintained the proper distance apart by the planks D D. The supports may, however, consist of piles or other rigid standards. They are so placed that the apparatus will stand at an angle, preferably about thirty degrees, to the direction of the current. Pivotally secured to the cables a a, at right angles thereto, by means of the clamps e e, the rod f, and the straps g g, are the propellers h. It the apparatus is to be used for raising water, as is the form illustrated in the drawings, bucketsvl are formed on the downstream or forward side of the propellers. These buckets are constructed in the manner shown in the drawings. Their ends are made at an angle to the propellerblade, so that they may not form an obstruction to the passage of the current, and their bottoms are formed at an angle, so that the current may tend to lift them and relieve the cables of a portion of the weight. Diagonal chains j j hold the propeller in a vertical working position. Theforce of the current bearing against the propellers 72. held thus vertically causes the propellers and cables to travel toward the downstream-support, lifting the filled buckets up the standards B and discharging their contents into the trough E, from whence it flows by gravity to-the desired points. In order that one cable may not work ahead of the other and twist the 'propellers,l provide the diagonal guy-chains 7c and allow each of the sheaves b b, c c, and d d to turn independently of its neighbor by journaling one or both loosely upon the shaft.
Projecting from each end of the propellerblade,near the bottom thereof, is the cranked axle 1, upon whichis secured the antifrictionroller m. This construction serves a double full of water is passing from its vertical toits downwardly-inclined position as the cables go over the sheaves dd the bucket hangs between the sheaves and forms the chord of the sheave-arc, while the cables are traveling in the are. Thus the lower end of the bucket is traveling slower than the cables against which it bears, and hence must slide back upon them. The antifriction-rollers mallow the buckets to do this without excessive wear upon the cables, which would be the case causes the bucket to be tipped suddenly and its contents to be discharged with less loss than otherwise. During the descent of the buckets the cranked axles hold them above the cables, and when passing around the sheaves b b they'drop over and are properly filled. The chains j j, which hold the propellers when working in a vertical position, unite where they cross into the ring n. By hooking these rings onto the hooks 0 on the rods f the buckets may be maintained in a purpose. It will be seen that when the bucket I without rollers. The cranking of the axle Z.
folded-up position, and thus the speed of the apparatus is gradually checked. After the buckets are folded up the upper boat A may be drawn in to the bank and the apparatus will. remain at rest.
The angular position of the apparatus secures independent pressure upon each of the propeller-blades, as one blade does not shield another. Since the propeller blades have plane surfaces on their current sides and are placed at right angles to the carrying-cables and at an angle to the direction of the current and are free to move in the direction of the cables, it follows that the force of the current upon the propellers will be all expended in driving them in the direction of their travel, and there will be no tendency for the cables to sag downstream. This operation will only result when the propeller-blades have substantially plane surfaces and are at substantially right angles to the direction of cable travel. This is important, asitobviates the necessity for guide-rails or other appliances to preventlateral sagging of the cables. In very turbulent streams, however, and in streams where a rocky bed causes the current to form eddies, it is sometimes desirable to provide a guide to prevent swaying of the cables. Such a construction is shown in Fig. 5, where the upstream-clamp e is extended into or connected with the arm 19, to which is adj ustably secured the grooved roller g. This roller rides upon the T-rail or inverted deckbeam 0', which'is supported, preferably,-in a somewhat tipped position across the stream parallel to the lower cables.
Although I have shown the apparatus equipped only for elevating water, it is obvious that it is adapted for other purposes, such as driving mills, drc.
Various changes of form, proportion, and construction may, of course, be made without departing from the spirit of my invention, and I do not wish to be understood as limiting myself to any specific construction further than is pointed out definitely in the claims.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
