Specification of Letters Patent.

Patented Dec. 13, 1910.
Serial No, 385,404.
5 and State of Wisconsin, have invented a certain new and useful \Vater \Vheel, of wlnch the following is a specification.
'lhis mveutlon relates to water wheels and specifically to water-.wheels of the type 10 known as impulse or impulse and reaction wheels, by which the energy of a moving jet of water is utilized, and more specifically the invention relates to a combination of apparatus for eit'ecting a regulation of such wheels according to the load imposed upon them or the power which is being consumed.
Referring to the drawings which accompany this specification and form a part thereof and on which the same reference 0 characters are used to designate the same elements wherever they ma appear in each of the several views,,and which drawings disclose an embodiment-of this invention,-
. Figure 1 is a perspective of a water wheel 25 apparatus embodying this invention; Fig. 2 is a plan view of the apparatus shown by 'Fi 1, parts being shown 1n section.
n the drawings the numeral 1 designates a shaft which is suitably supported by proper bearings, and upon this shaft are keyed the water'wheels 2 and 3 and the pulley 4. y y I The numeral 5designates the water sup- .ply pipe to which the nozzle 6 is hinged so as to be movable in a vertical plane, the nozzle 6 being provided with the two branches 7 and 8 through which the water is directed respectively to wheel 2 and to wheel'B, each'of these branches being ro-i vided with an orifice 9 and 10 adapte to be controlled respectively by the manually adjustable valves 11 and 12.
The numeral 13 designates a power or relay cylinder provided with a piston (not shown) and piston rod 14, the piston rod being secured to nozzle 6 and being adapted tomove said nozzle 'up or down whereby the water issuing from the orifices of the nozzle is directed'fagainst the'buckets 15 of the wheels, or-is delivered below said buckets without impinging thereon, the movements of said piston and piston rod being caused by a fluid under pressure, referably water, which may be taken from t e pipe 5,
and which is admitted into one or the other end of the cylinder 13, through the valve chest 16, by means of any suitable valve mechanism actuated by the valve stem 17.
The numeral 18 designates any suitable or preferred type of governor, the specific type shown being an ordinary fly ball t pe which is actuated from shaft 1 by the elt or equivalent motion transmitting mechanism 1!), the governor being connected by the levers 20 and 21 with the valve rod 17, the lever 21 being also connected by the pivot 22 with the iston rod 14, this specific arrangement of parts being an ordinary typeof relay mechanism rendering the governor static in its operation. In other words, the piston rod 14,, when it moves causes the admission valvc connected to valve stem 17 to be seated, whereby a step by step movement of the piston rod 14 results-as the speed of rotation of the shaft 1 decreases or increases.
The operation of the apparatus is as follows: Two or more wheels being secured to the same shaft and the number of branches I of the nozzle 6 corresponding with the numher of wheels, if the valves controlling the I orifices of said branches be open, the power developed on shaft 1 will be proportional to" the number of wheels, assuming-that the water acts with constant velocity resulting from a constant head. If, now, the worl;
required and the power taken from shaft ii,
is the full power which can be developed by the wheels when all are at work, the speed of rotation of the shaft 1 will remain constant; but if less power is required, the speed of said shaft will increase, the governor balls will diverge and the jets of water will be deflected more or less from the buckets of the wheels, resulting in a great waste of ivater. If, however, one of the valves be now closed, the speed of the wheelswill be diminished )roviding the jets are lmpingin a ainst he buckets at all, with the resut hat the remaining jets or 1st \\'lll. be
power developed is equal to the power consumed, when the speed of rotation of the shaft 1 will again become constant. combination of a plurality of wheels and a )lurality of jets gives a wide range of regulation running from a fraction of a single jet acting upon a single wheel, up through 'directed more on to the buckets until the.
This
all increases uf'pou er t0 thepoint wher all.
are acting at capacity upon all the Wheels. I
What, I claim 15,- The combination with a a shaft, of a plu-' rality of Water jet actlmtable Wheels thereon, a pipe tur supplying Water to said wheels, :1 lnxxnchedggozxle hinged to said pipe at a sin I l I l I provided with a valve for controlling the flow of watertheretlnbou h a overnor re-,
? sponsive to the changes of speed of said shaft, and u singleregulzitmg means controlled by said governor for raising and lowering said branched nozzle.
In testimony whereof, I ailix my signature 20 in the'presenee of two witnesses.
