WATER-MOTO R.

SPECIFICATION forming part of Letters Patent No. 470,190, dated March 8 1892.

Application filed'February 26, 1891. Serial No. 382,934. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL B. GOFF, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Improvement in Water-Motors, which improvement is fully set forth in the following specification and accompanying drawings. I

' My invention relates to improvements in water-motors; and it consists of the combination of parts hereinafter set forth.

Figure 1 represents a vertical longitudinal section of a motor embodying my invention. Fig. 2 represents a horizontal section on line 0c 0:, Fig. 1. Fig. 3 represents a horizontal see- Fig. 4 represents a horizontal section on line a .2, Fig. 1. Fig. 5 represents a side view of a detail portion of the device. Fig. 6 represents a plan view of novel gates with racks embodied in my invention. Fig.7 represents a perspectiy e view of a portion of a gate-rack, showing the double ratchet-teeth.

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

Referring to the drawings, A and B designate, respectively, two vertical cylindrical tubes connected at their lower ends by a passage-way or pipe 0, preferably of circular form. Said tubes and pipe are provided with suitable supports D for maintaining the same in proper position. Within the tube A is a vertical shaft E, suitably journaled and having thereon a water-wheel F, adapted to rotate the shaft by the falling of the water thereon which is admitted into the upper end of the said tube. WVithin the tube Bis a vertical shaft, G, suitably journaled and carrying the spiral blades H, whereby a current of water through said tube causes the rotation of the shaft. Leading from the upper end of the tube B, below the upper end of the tube A, is a tube J, slightly inclined, so as to give a fall to the water in its passage from the tube 13. Connected with the tube J at its lower end is a vertical tube K, having suitable supports L for maintaining it in position. Within the tube K and connected therewith by arms or braces M is an open cylinder N, so located as to form, an annular channel or passage P between it and the said tube. A shaft Q is located with said tube K and cylinder N, havnected to the cylinder by the braces V, so asto be stationary. Mounted on the shaft Q below the said sleeve is a turbine wheel W, having the inner blades X and the outer blades Y, the water reaching the said inner blades by the openings Z in the top of the wheel and the outer blades by the openings A in the sides thereof, the said openings Z communicating with the inside of the cylinder N and the openings A communicating with the channel P by means of the connecting passageways B.

Below the turbine wheel NV and on the shaft Q is secured a wheel 0, composed of an inner and an outer shell, each of which is fastened to the said shaft. The outer shell D is open at its top and incloses the lower ends of the blades Y of the wheel IV, so as to receive the water from both sets of the blades of the said wheel. Leading from the inside of the upper portion of said shell D are horizontal passage-Ways E, with openings through which the water passes to the blades F of the wheel. Connected with the lower end of the tube K-are channels G, leading from the annular passage or channel P to openings in the wheel above the outer set of blades H. Movable in guide J, connected with the lower end of the tube K, are the gates K, formed of semicircular body portions L, adapted to cover the upper ends of the channels G, so as to shut off the water falling from the channel P, side pieces M, working in the guides J, and racks N, attached to said body portions. The said racks are provided with two rows of ratchet-teeth, inclined in opposite directions, so that each of the gates may be moved in either direction by means of a lever P, pivoted'to an arm Q of the tube K and provided at its lower end with the two pawls R, which are either ongaged with or disengaged from the ratchetteeth by means of a string or cord S, attached thereto. An arm T, secured to the tube K,

serves to keep the lever P in place, preventing further movement than is proper of the same.

The operation of the motor is as follows: The current of water passing in the upper end of the tube A will cause the wheel F to rotate, thus imparting rotary motion to the shaft E. As the water rises in the tube B, the spiral blades II will rotate, thus operating the shaft G. \Vhen the water has risen to the top of the tube B, it will flow through the tube J to the tube K, and as the walls of the tube J are inclined the flow will be accelerated, thus giving increased power to the current which enters the upper end of the tube K and cylinder N, the portion that passes through the said cylinder N being deflected by the blades T, so that it strikes at a greater angle the blades X of the turbine \V than it would if it would fall directly thereon, and the water which passes through the channel P being directed by the channels 3 so as to strike the walls A at nearly a right angle. A portion of the water from the channel I passes through the channels G to the outer blades II of the wheel 0, and the water escaping from the wheel passes to the inner blades F of the said wheel 0, so that the latter is rotated. Owing to the rotation of the two wheels 011 the same shaft, increased power is given to the same. If it is desired to shut off the water-supply from the outer blades II, the gates K are closed by means of the levers P, the proper pawl R being engaged with its ratchet-teeth.

It is evident that either or all of the shafts can be connected with any suitable device by means of gearing, so as to operate the same, or that the shafts may be connected together so that the power or momentum of all can be combined.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a water-motor, the combination of a vertical tube, a rotary vertical shaft, a cylinder secured to said tube within the same and surrounding the shaft, a sleeve surrounding the shaft and secured to the cylinder, inclined blades on said sleeve, and a wheel on said shaft below said sleeve with blades receiving the water from said inclined blades on the sleeve, substantially as described.

2. In a water-motor, a vertical tube, a rotary shaft therein, a cylinder secured to said tube within the same and forming an annular channel between the walls of the said tube and cylinder, a sleeve surrounding the shaft and secured to the cylinder, inclined blades on said sleeve, a wheel on the shaft below the sleeve provided with inner and outer blades, and channels leading from the annular passage to openings in the sides of the wheel, said parts being combined substantially as described.

3. In a water-motor, a vertical tube, a rotary shaft therein, a stationary cylinder forming an annular passage or channel within the said tube, stationary deflectors within said cylinder, a wheel on said shaft below said deflectors having inner and outer blades, a second wheel provided with inner and outer blades and mounted on said shaft below'said first wheel, and channels or passage-ways leading direct from said annular channel to the outer blades of the said second wheel, said parts being combined substantially as described.

4. In a water-motor, a shaft having the wheel IV, with the blades Y thereon, and the wheel C, consisting of an inner and an outer shell, the latter being open at the top and inclosing the lower ends of the blades Y and having in its upper portion horizontal passage-ways with openings, said parts being combined substantially as described.

5. In a water-motor, a tube with an annular passage therein adjacent to its wall, a wheel in said tube with openings therein, communicating passages leading from said annular passage to said openings, and gates having semicircular bodies provided with racks having two rows of oppositely-inclined ratchetteeth and side pieces, and a pivoted lever carrying two pawls, said parts being combined substantially as described.

6. In a water-motor, the combination of a tube, a rotary shaft, a cylinder within the said tube forming an annular passage or channel, a wheel on said shaft below said cylinder, and a second wheel on said shaft below said first wheel, said wheels having inner and outer blades, the inner blades of the upper wheel being adapted to receive the impact of the water falling within the cylinder, the'outer wheel to receive the water from the annular channel, and the inner blades of the lower wheel to receive the water escaping from both blades of the upper wheel and its outer blades to receive water direct from said annular channel, substantially as described.
