' WATER-WHEEL.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 4, 1905. Serial No. M LIOQ.

To all whom it may concern:

Be it known that I, OBED HAND NORDSTROM, a citizen of the United States, residing at Punxsutawney, in the county of Jefferson and State of Pennsylvania, have invented certain new and useful Improvements in 'Water- Wheels, of which the following is a specification, reference being bad therein to the accompanying drawings.

My invention relates to water-wheels, and more particularly to that class of turbinewheels wherein the water operates upon a series of blades or buckets, one of the objects being to provide a device of the character described wherein the water shall be conveyed against and upon said blades or buckets through a plurality of channels, each channel leading directly into the chamber in which the buckets are arranged and by reason of which a number of streams of water will en gage with said blades or buckets simultaneously.

A further object of my said invention is to procure a device of the character described in which the water can be automatically turned on through a number of channels by operating the valve to one of the channels and whereby it may be turned off by the same means.

A further object of the invention is to provide a valve that may be also used as a cutting-blade and which acts as such when weeds, grass, or other growth comes in contact with said valve, thereby keeping the entrance therea to constantly free from such obstructions.

A still further object of the invention is to provide means to overcome the resistance offered by the valve sticking in the valve-seat and whereby the valve may easily be operated.

' Further objects and advantages of the invention, as well as the structural features by means of which said objects are attained, will be made clear by an examination of the specification, taken inconnection with the accompanying drawings, in which the same reference-numerals indicate corresponding portions throughout, and in which- Figure 1 is a side elevation. Fig. 2 is a central vertical section. Fig. 3 is a detail of the wheel carrying the buckets. Fig. llis a detail elevation of one of the valves. Fig. 5 is a detail side elevation of the double cams at the top of the valves. Fig. 6 is a top plan. Fig. 7

is a horizontal section. Fig. 8 is a view showmg the application of my device.

detail elevation illustrating the adjustment of the lower bearing of the main shaft, and Fig. 10 is a sectional view showing the ball-bearings between the double cams.

l designates aframe in which is adjustably mounted a platform 2, supporting a shaft 3, having an enlarged base 3', said shaft carrying the cylinder 4, which has secured thereto or formed integral therewith the bucket-blades is adapted to rotate.

8 designates openings in the platform 2 beneath the ball-bearings in order that sand which may accumulate in the races in which the balls are adapted to rotate may be washed out, leaving the races-clear and unobstructed.

The water is given ingress to the bucketblades at four points, and as the arrangement of parts by means of which the Water is conducted to the blades is similar in each a de scription of one will suflice for all.

A gear-wheel 9 is loosely mounted upon the shaft 3, said gear-wheel being engaged by a cog-wheel section or segment 10, having a number of cogs thereon adapted to fit those upon said wheel 9. This cog-wheel section 10 is rigidly mounted on a shaft or stem 11, which has rigidly secured thereto or formed integral therewith a valve 12, having an opening 13 with sharp cutting edges 14, said valve being mounted to turn in a cylindrical valveseat 15, having openings 16 to admit the water, which passes into a chute 17, where it is These bucket-blades are cam-shaped, being narrow at the top and wide at the bottom and are covered by a plate 18, rigidly mounted on top of the cylinder 4 and which effectually holds the water within the chute. The peculiar shape of the chute 17 causes the water to form a wedge by means of which it is given an extra force, all of which is exerted against the bucket-blade, which being spiral in shape has also the weight of the water upon it, which augments the force against it, and which weight necessarily increases as the water approaches the lower end of each bucket-blade, the volume of water being greater at the lower end than at the upper. The shaft or stem 11 turns in a plate 19, rigidly mounted on, the frame 1 and having thereon a cam projection 20, engaging with a corresponding cam projection 21, rigidly mounted on saidshaft or stem, the two constituting a double cam. Each of said cam projections 20 and 21 has an adjustably-mounted cam-ring 22 of any suitable material and held in place by the setscrews 23. Ball-bearings 24 are interposed between the cam-surfaces and are held in place by said cam-rings, the edges of which extend beyond the cam-surfaces 20 and 21, the balls traveling in a race in the cam-surfaces, as shown. The object of this last-described arrangement of parts is to provide means for slightly raising the valve 12 in turning it in order to lessen the strain caused by said valve sticking in the valve-seat as the valve is given a vertical movement simultaneous with the horizontal.

The shaft 3 is mounted at its upper end in roller-bearings 25 and turns in a casing of' Babbitt metal 26 to avoid wear and at the same time to preserve precision in the operations of said shaft. The platform 2, carrying the ball-bearings 8, upon which said shaft 3 rotates, is adjustably mounted in a frame 27 by means of the set-screws 28. The object of this last-mentioned arrangement of parts is to provide a means for keeping the shaft true at all times, so that if any of the parts become worn and the shaft thereby becomes out of plumb it can be returned to a perfectly vertical position by said arrangement.

Connected with the main frame 1, in which my said device is mounted and which constitutes a part of it, is a box or flume 29, which surrounds the entire device and carries the water to all of the openings 16, so that it may be turned on at all points simultaneously.

In operation the valves are opened by means of a hand-wheel 30, mounted on one of the shafts 11, motion being imparted to the remainder of said shafts 11 by means of the gear-wheel 9, which engages with all of the cog-sections 10, as heretofore stated. When said valve 12 is opened, the water rushes in, as indicated by the arrows pointing to the opening, and comes in contact with the bucketblades 5, as heretofore explained, and descends upon said bucket-blades and passes out, as indicated by the lower arrows in Fig. 1, into a fiume 31.

Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
