STEAM-TURBINE.

To all whom/{today concern:

'. '-Be*it:kxi1own that I, JOHN E. KILKER, a

citizen-"of the United States, residing at- ;ohicagb;*in*the county of Cook andState of Illinois,"'have invented a certain new and usef uljlmprovement in Steam-Turbines, of

which the following is a Specification.

My invention relates to steam turbinesand as fo'rits object to provide means whereby 10- "the "engine may "befregulated, or steam be cutout'in the 'event'of the use of a regulatdeviceiwhich for any reason has Thefinvention the preferred 'forrn fis illustrated "in"theaccompanying drawings Figure 1 is an elevation of'a turbine with parts'broken away t'o'sh'ow other parts in operative position; Fig. 2 is a Similar view with partsbroken away to show the engine cutout.

' Like parts are indicated bythe same lotterin both of the figures. H Y A the casingwhich incloses all of the parts. "A shaft'B runs 'from end toend of the machine'carrying at the right the dynamo-or other driven part, It is mounted insuitable bearings.

' 'C- is a diaphragm about the shaft with packing grooves C and a spring groove C to receive one end of the spiral s'prlng C which encircles the shaft. The other end of 7 this s ring bears against the ball-bearing device 8, the inner ring of which is rig1d on a reduced portion of the shaft B and the outer ring of which bears upon the collar 0 which is rigidlysecured to the diaphragm C. .SThusthe spring is received into a pocket and tendsalways to hold the shaft toward vtheright, that isfin operative position as illustrated in Fig.1.

1) is the left-hand end of the shaft B in a boss D on the turbine wheel D and there is a-clearance space I) so that the shaft may be moved a certain distance toward the left if the springC be sufliciently flexed.

E, E are the buckets normally in opposition to the nozzles Eto which the steam is led through the pamge E from the valve chamber E. The steam enters this chamher from the. opening E" which is controlled by the valve E. I do not dwell upon "the details of the construction of this valve Specification of Letters Patent.

The valve has a stem F. and is encircled V tentedAug- 1916-. g Application filed May 21, 1915. i Serial No. 29,487. Y

by a spring F which tends to keep it'ofl" its seat. It 1s connected to one'arm-of a lever F which is pivoted atF and has a'roller F which engages one end, of a le-ver F 5 which is pivoted at F 0 and is bifurcated, its

two ends encircling the ring F and piv otecl'thereto at oppo'site's'ides by pivotsF".

The details'lof this construction form" no part of the present'inv'ention. The ring F" bears againstone end of'the sleeve .G which surrounds the shaft is provided with a sp ng G connected .tofthe'adjustable collarlG" controlled 3. series'of screws G ThlS spring s adjusted so as the sleeve toward. the left.

J isone of a series of governoryweights to tend-to force hevingea-cha Pivotal bearing J1 against the? wheel, a weight arm J and a toe J which lies under the end of the sleeve G. These several parts form no part of'the presentv invention, but they are described sufiiciently to serve as an explanation or 'descriptionof one form of an apparatus which contains my invention. 7 I

It will be understood that I do not wish to limit my invention to the use of the particular device here shown except to the extent indicated in the appended. claims.

The use and operation of, my invention are as follows: Assuming a structure shaped as here shown, it is evident that when for any reason the turbine wheel begins to rotate rapidly the governor Weights will be rocked on their pivots, the toe of the governor levers will force the sleeve G toward the right against the action of the spring G and this will move the ring F toward the right and rock the lever F .on its pivot. This in turn will rock the lever having the ,arms F and F and force the valve stem In the meanupwardly to seat the valve. time the parts are all held in general operative position'by the spring C If new thevalve fails to work, if, for example, it has been so worn that the steam continues to pass through the valve after the governor has performed its entire function, or if there be an obstruction between the valve and the seat so that the governor can not completely seat the valve and cut ofi the steam, then if the load be cut ofi the wheel, will continue to rotate under such restricted supply of steam until the operation becomes dangerous or destructive. With'the 10 arrangement here shown, however, as soon as the governor weights have operated to move the sleeve G as far to the right as possible, if the speed increases or continues, the point J ceases to be the fulcrum of the governor weight, the point J 3 becomes such fulcrum andthe wheel is forced to the left into the position indicated in Fig. 2 where the buckets are out of register with the nozzles/and the steam has been cut off from the buckets. The wheel therefore must tend to stop and the operator will speedily observe that something is the matter and will inthe speed of the wheel, a valvecontrolled by said governor to control the supply of steam, means responsive to, the operation of the governor for moving .said'wheel out of the normal relation with the'nozzle.

3. The combination with a turbine wheel and steam supply nozzle of a valve for controlling the supply of' steam to the nozzle, a-

governor operated by the wheel for controlling said valve, and means responsive to the operation of thegovernor and operative after the manipulation of the valve by the governor for displacing the wheel out of register with the nozzle.

4. The combination with a turbine wheel and steam supply nozzle of a valve controlling it, a governor actuated by the wheel to control the valve, and a connection between the governor and the wheel to laterally displacethe wheel in response to excess rotational speeds. thereof to throw the wheel out of line with the nozzle.

5. The combination with a turbine wheel and steam supply nozzle of a valve for controlling the supply of steam to the nozzle, a governor operated by the wheel for controlling said valve, and means responsive to the operation of the governor and operative after the manipulation of the valve by the governor for displacing the wheel out of register with the nozzle, and yielding means for normally holding the wheelin line with the nozzle.

6. The combination with a turbine wheel and steam supply nozzle of a valve controlling it, a governor actuated by the wheel to control the valve, and a connection between the governor and the wheel-to laterally displace the wheel in response to excess rotational speeds thereof to throw the wheel out of line/with the nozzle, and yielding means for normally holding the wheel in line with the nozzle.

7. The combination with a turbine Wheel and steam supply nozzle of a valve for controlling the supply of steam to the nozzle, a.

governor operated by the wheel for controlling said valve, and means responsive to the operation of the governor for displac'- ing the wheel out of register with the nozzle.

In testimony whereof, I afiix my signature in the presence of two witnesses this 18th day of May, 1915. 4
