TURB INE r Specification ofLetters Patent.

Patented April 7, 190s.

Application ledDceember 28, 1905. SeriafNo. 293,700.

To all whom it mayroncrn:

Be 1t known that I, WILLIAM A. LoUDoN, a

citizen of the UnitedStates, residing at Chi-4 cago, in the county'of Cook and State-of Illinols, have invented anew and useful Automatlc Turbine, of' which the following is a specification.

Myinvention relates to turbines, which arel provided on their eriphery With a plurality of buckets or poc ets intowhich fluid is forced at a tangent, and the o jectsof my improvement are first, toautomatically decrease-or increase the size or area of the` buckets Aas the vspeed of the turbine may require-while 1t 1n action, second, to so connect the movingy parts in the buckets that they will allmove-in unison; third, to con- `the buckets and when the turbine attains the n desired speed the buckets are automaticallyl decrease in capacity so as to retain the -des'ir'ed speed. It is immaterial in what manner this regulation of the area or capacityv of the buckets is accomplished, and I have shown several modifications. v

Another modication not shown may be v made by constructing two disks or wheels adjacent to each other and provided with intermeshing teeth in such manner that by shiftin the wheels with relation to each other t pockets orbuckets formed between the teeth of the wheels are variedv in area or Vo describe my invention so that others versed inV the art to which it pertains can understand it suiiiciently to make and use the same, I have illustrated `it on the accompanying sheet of vdrawing in which:

Figure 1 is -a fragmental cross sectional view through a turbine embodyin my invention; Fi ..2 is a detail sections. View of a ig. 3 is a similar View to Fig. 1, of a modication;'Fig. 4 isla similar View of anressurey other modification and Fig. v5 is a sin'iilar view of still another modification. l

l Similar reference characters refer to similar arts throughout the several views.

eferring toig. 1 and 2, the steam chest 6 is secured to the casing 7, within which is mounted to rotate about the shaft 8 the turbine wheel 9. The periphery of the wheel 9 is provided with a plurality of pockets 10,. into which the steam from the steam chest 6 is discharged through thenozzles 11. Movably mounted in each pocket 10 is a piston or partition 12 secured to a pin 13 extending through a hole provided therefor in the rim of the wheel 9 which pin has on its exposed 415, so as to normally hold the piston 12 in against the bottom of the pocket 10, thus leaving the' open end of the pocket unobstructed to the action of the steam from the nozzles 1 1.

All the springs 15 are adjusted, by turning the nuts 14, to resist the radially outward pull, caused by the centrifugal force on the pistons and Atheir connections, until a desired` speed .of thewheel 9 isattained. Should the Wheel 9 for any reason tend to revolve faster than the desired speed the centrifugal force of the pistons will overcome the force of the springs and will move radially outward in the pockets, thus partially or totally obstructing the open end of the pockets, which will act t'o decrease the speed ofthe wheel 9 because the steain from the nozzles 11 will be artially or totally prevented from' enteringtiie pook'- ets 10.

It will be understood that an intermediate position of the pistons 12 will act as a control over' the wheel 9 and the .full outer position of said pistons Would act to stop the Wheel entirely, by closing the entrance to the pockets.

To prevent any possibility of the pistons 12 movin out beyondthe peripheral surface Vof the w eel 9, I preferv to have the side lianges 16'of the wheel provided with the cilL cumf'erential rim 17 which will serve as a stop for the pistons.

In Fig. 3, the exposed ends of the pins 13 are shown as being pivotally connected to one arm' of a bell-crank lever' 18 which is pvoted to thewheel 9 at 19. The other arm of the bell-crank lever 18 is pivotally secured to a iioating ring 2() which is normally pulled by a spring 21 in such direction asto I swings about the pivot 38, by reason. of the holdlthe pistons-12 down the bottom ofthe y pockets 10.

, periphery of the Wheel. f The'disk 22 'is'pr -vided With an eccentric pin 24 which isenin Fi .4, interposed @miser et@` ins ..13 are shown as bein connected to a isk 22 pivoted about the shaft 8 by-conneo rods 23 in such manner thatthe of the.. -4 i 'ullthepistons'iZ in'toward the bottoms o the ockets4 andv turning the disk in anopposite irectionwill .disk in one direction will allow the pistons to move out toward' the gaged'by the forked arm of a-bell-crank'lever 25 pivotedto the Wheel 9 at 26 and having its other arm 4providedjwith a Weight 2,7, so.

periphery With pockets having the lids 31 which are pivoted at 32 and each is provided With an arm^33 extending throu ha slot provided therefor in the rim of t e Wheel 29.. The free end of each arm 33-rests in a recess 34 rovided in a ring 35. The ring 35 is provi ed with one or more pins 36'Which are engaged by the slotted arm of a bellvcrank .lever 37'- pivoted to the vvheel 29 at -38 and having its other arm provided With a Welght 39, in such manner thatwhen the Weight 39 centrifugal force createdby the rotation ,of ythe Wheel 29, the bell-crank lever 37 will .move the ring 35 so'as tovswing the lids 31 across `the open end of the pockets 3() and thus decrease the size of .the Dockets exposed to the blast of'steam from the nozzles 11.

Y The movement ofthe Weight 39 is controlled by a'spring 40.

increasing the area vof ther pockets exposed tothe jets of steam are capable of radical' change from the. constructions shovvn'without" in the Yleast the invention.' l Havin Ithus fully v what I c aim .as new anddesire-to secure by Letters Patent vof the United States isY: -l
