POWER GENERATOR.

Application filed March 24, 19-24. Serial No. 701,478.

This inventionrclates to powerunits, and more particularly to turbine units, such as steam turbines.

Cne of the objects of this invention is to f provide such a power unit having a novel arangement of governor niechamsm which is iple to construct and effective in operation. 7

Another object is to provide such a unit in "which the. governor mechanism is so located s not to be subject to corrosion or other deterioration of its bearing surfaces and the like.

Another object is to provide such a unit in which the governor mechanism is simple and requires no adjustments.

Further objects will appear from the de tail description taken in connection with the accompanying drawing, in which:

Figure 1 is a view in elevation, partly in.

section. showing aturbine unit embodying this invention; and

Figure 2 is a detail of the governor mounting taken on line 2-2, Figure 1.

Referring to the accompanying drawing, 1 designates a base or pedestalwhich supports the unit. This base is provided with bearings 2 and 3 which carry the operating shaft constructed in sections. This operating shaft comprises a turbine shaft a workingin the bearing 2 and a driven shaft 5 working in the bearing 3. The power receiving device 6 which may be a belt wheel, a grinding wheel, or other device to be driven, is mounted on the outer end of the driven shaft as shown in Figure 1.

The pedestal 1 may be provided with a plate 7 on which 1s mounted a casing 8 adapted to house theturbine wheel or runnor 9 mounted on the turbine shaft 4. The casing is provided with nozzles or jet openings 10 connnunicating with the supply duct 12 for directing the power supplying fluid, such as steam, against the vanes of the wheel 9. One or more jets 10 may be provided according to the power to be devel oped. An exhaustconduit- 11 leads the spent fluid from the casing 81 The turbine shaft 41 extends through the bearing 2 to the outside of the casing. On the outside of the casing it is connected to the driven shaft 5 by means of a telescopic connection. The shaft 5 is provided with a reduced portion 13 and provided at its end with a plug or cross-head 14; adapted to fit within the bore 15 ofthe llol Qw turbine sha t? A pr g tenors.

head 14 so as to urge the shaft 4 to the left.

' Figure 1, in order to maintain the wheel 9 in normal position in alinement with the jets 10. It will be understood that the shaft 5 is restrained from longitudinal movement in the bearing 3 by the collars 17 and 18. The shaft 4 is provided with a head 19 providing a shoulder adapted to abut against the hearing 2 to limit the movement of the shaft l to the left, Figure 1, and to position the turbine wheel 9. A split collar r cap 20 is adapted to fit the reduced portion 13 of the driven shaft and is rigidly fixed to the head 19 so as to retain the head 1 1 within the bore It will be clear that the shafts 4: and 5 are thus connected by a loose telescopic connection so" as to permit longitudinal sliding movement of the turbine shaft 1 in the bearing 2 for a purpose which will be described presently. tluch longitudinal movement is, however, opposed by pressure of the spring 16. i

clamped between the head 19 and the split collar 20 is a resilient plate 21 whose tapered ends extend radially in opposite dis rections from the shaft. The outer ends of the plate 21 are bent laterally as illustrated in Figure 1. Rigidly fixed to the shaft 5 by means of a pin 22 or other suitable fas tening is a collar 23 provided-with a shoulder 2%. A plate 25 similar to the plate 21 is mounted on the collar 23 and clamped to the shoulder 2 1 by means of a collar 26 as illustrated in Figure 1. The plate 25 is similar in form to the plate 21 and has radially 1 extending ends bent laterally in a similar manner but in the opposite direction from that of the plate 21. Thus it will be seen that the plate 25 is rigidly secured to the shaft 5, while the p ate 21 1s rigidly secured to the head 19 and the shaft 4:. Mounted between the extended ends of the plates 21 and 25 is a pair of centrifugal elements or governor weights 27. The weights 2? are rigidly secured to both plates 21 and 25 by means of bolts 28 or other suitable fas The plates 21 and 25 are thus rigidly secured together through the governor weights 27 and since these plates are rigidly secured to the shafts 1 and 5 respectively, a driving connection is thus estabcircumferential direction so that it is capubic o torque, yet permits by its tiexi rlVC: longitudinal movelu other words 2 while fi on may torque from the shaft to l; and 5.

be transmit the shaft In the operation of this device the driving fluid being admitted to the casing through the l0 w'll impinge upon the vanes of the turbine wheel 9 so as to drive the same in rotation. The turbine wheel through its shaft -l and the connections 21, 235 will then drive the shaft 5 and the power receiving device (5. its the speed of revolution app catches a predetermined point, the cent'rif al force of the governor weights 2?, being exerted radially outwardly, will tend to expand the flexible frame comprising the connections 21, Since these connections are resilient, such expansion takes place and will be accompanied by a corresponding contraction of the frame a longitudinal direction witl respect to the shafts. Such contraction will have the effect of drawing the shaft to the right, Figure 1, sliding the same in the bearing 2. The shaft 5 will not move as it is confined bc tween the collars 17 and 1S. the shaft 4; moves to the right, the wheel 9 moving therewith will gradually pass out of registry with the jets 10. Upon passing out of registr the power delivered to the wheel 9 by the jets wil be correspondingly diminished and hence the speed will be correspondingly reduced. Upon reduction of the speed, the centrifugal force exerted by the we" ;lits 2. will also be reduced and the resilience of the frame 21, assisted by the pressure of the spring 16 will operate to return the wheel 9 to its normal position in registry with the jets 10. It will be clear, therefore, that by properly adjusting the resilience of the at th .J

name 21, 25 and the spring 16, the governor can be made to maintain the speed of rotation substantially constant at a predetermined value.

It will be noted that in accordance with the presentinvention the governor mechanism )ltlCGCl entirely outside of the casing which houses the turbine wheel. The worting parts of the governor mechanism are thus removed from liability of corrosion, such as does occur in devices where that mechanism is placed within the steam charnher. The steam invariably carries with it certain impurities which are injurious to the metal parts and operate to corrode and roughen the bearing surfaces and render the operation ofthe device erratic and unreliable. Iii-accordancewith this invention,
