ELASTlC-FLUID TURBINE..

SPECIFICATION forming part of Letters Patent No. 767,250, dated August 9, 1904.

Application filed June 15, 1904. Serial No. 212,603. (No model.)

To [all whom, it muy concern:

Be it known that I, AUGUST SCHNEIDER, a citizen Aof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Elastic-Fluid Turbines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in an elastic-fluid turbine, the object being to provide a simple and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a central longitudinal section of a turbine constructed in accordance with my invention. Fig. 2 is a developed section, on an enlarged scale, on the line 2 2 of Fig. l, illustrating the fluid-passages of the engine.

My said turbine comprises two hollow supporting-standards A and B, forming the steam or other elastic-fluid inlet and exhaust, respectively, the upper end portions of said standards A and B being' curved to form elbows between which the casing C of the turbine is mounted and supported. The said casing C is composed of a plurality of sections D of gradually-increasing diameters, which are secured together by means of bolts passing through the circumferential flanges E thereof. The standard or inlet A is of smaller diameter than the standard or exhaust B, and the interposed casing C is conical. Each of said sections D is provided with an internal annular flange F at its smaller end, and in the outer face of said flange is an annular recess G, the peripheral walls of which are beveled, and on the opposite faces of said flanges are beveled annular projections H. In said flanges I provide passages J at regular intervals, said passages being disposed midway between the ends of said flanges and curved so that the steam or other fluid entering one end of each of said passages in a given direction is deflected and leaves said passages J in an opposite direction, said passages being wider at their inlet than at their no unnecessary resistance is developed. end sections D are provided with central opendelivery ends. Passing centrally through said casing C and journaled in bearings K, carried by said standards A and B, is a shaft L,which carries a plurality of disks M, each of which is adapted to fit and rotate within one of the sections D of the casing, said disks being provided adjacent their peripheries with passages N, corresponding in number and registering with the passages J, but oppositely disposed, so as to cause the steam or other fluid to travel in a zigzag direction through both sets of passages J and N. Adjacent their said peripheries the said disks M are provided in one face with annular recesses O, adapted to receive said projections H of the flanges F of the sections D, and on their other faces with projections P, adapted to enter the said recesses Cr of said flanges F, said sections D and disks M being adapted to relatively intert snugly at all points, but allowing sufhcient freedom to avoid undue friction. It will be noted that said passages J and N are so formed that at their inlet ends the fluid is deflected slightly in one direction and toward and at their delivery ends it is deflected sharply at a greater angle in the opposite direction, but always in a relatively gradual curve, so thlat T ie ings, forming bearings for said shaft L, while the intermediate sections are preferably cut away as much as possible at their middle portion to reduce weight. In the walls of said standards A and B, I provide stuffing-boxes Q for the shafts L to prevent escape of' steam. The said shaft and the. bearings K are provided with interiitting annular grooves and projections which serve to hold said shaft against longitudinal movement.

Adjacent the endmost section D of the casing and within the inlet A is a sleeve R, which is secured to said section and on which the hub S of a valve T is longitudinally movable,

said valve T being ring-shaped and disposed y in front of the passages J of said section D. On said sleeve R is a shoulder U, which serves to limit the closing movement of said valve to prevent the same from completely shutting olf the supply of steam to said passages. Pivotally mounted on said hub S and on the pro- 100 jecting inner wall of the stuffing-box Q are two toggle-levers V, which are pivotally connected at their other ends with a plunger W, passing' vertically throug'h a stufling-box provided therefor in the upper wall of the standard A and carrying a collar X at its extreme upper end, between which and a part of the frame Y a spring' is interposed which serves to normally hold said plunger at the upper limit of its movement and hold said valve T at the rearward limit of its movement. The said plunger W is connected in a well-known manner with a centrifugal governor Z of well-known construction, which is geared to the shaft L and serves to depress said plunger, and thus move said valve T forward to partially shut off the supply of steam or other fluid when the speed of the shaft L exceeds the predetermined number of revolutions.

Suitable lubricating' devices and means for primarily adjusting the valve T may be provided.

The operation of my turbine is very simple, the projection of the steam or other fluid against the walls of the passages N serving to cause the disks M, and therebyT the shaft L, to be rot-ated, the said steam or other fluid gradually expanding during its passage and acting on correspondingly larger surfaces until it reaches the exhaust B.

The interfitting recesses and projections on the disks M and on the flanges F of the sections D serve to efficiently overcome a great deal of leakage and back pressure, while the zigzag passage of the steam in ogee curves instead of sharp angles produces greater elllcieney by reason of the fact that resistance is decreased.

I claim as my invention-A l. An elastic-fluid turbine comprising in combination a conical casing connected at its smaller end with a steam-inlet and at its larger end with an exhaust, said casing being composed of a plurality of substantially cylindrical sections, an internal annular flange on each section provided on one side with an annular recess and on its other side with an annular projection, a shaft passing centrally through said casing and carrying disks corresponding in number and interiltting with said sections, said disks being provided adjacent their peripheries with annular recesses, and projections interfitting with the projections and recesses of said flanges of said sections, said flanges and disks being provided with relatively zigzag passages registering with each other, substantially as and for the purpose described.

2. An elastic-fluid turbine comprising in combination, a conical casing connected at opposite ends with an inlet and an exhaust, a plurality of internal annular flanges on said casing, a shaft passing centrally through said casing, and disks on said shaft extending at their peripheral portions between said flanges,

said flanges'and disks being provided with passages for the driving fluid, said passages being curved between their ends and serving to deflect said fluid in one direction at their inlet ends and in an opposite direction toward their outlet ends at a greater incline, said passages in said disks being relatively oppositely disposed to the passages in said flanges and serving to cause the fluid to pass zigzag in ogee curves.

3. An elastic-fluid turbine compi'ising in combination two hollow standards forming respectively an inlet and an exhaust for the fluid, a conical casing interposed between said standards and communicating therewith, said casing being composed of a plurality of substantially cylindrical sections each provided with an internal annular flange having an annular recess on one face and an annular projection on its other face, a shaft passing centrally through said casing, and a plurality of disks on said shaft extending between the flanges of said casing and each provided in its opposite faces with an annular recess and projection respectively adapted to interfit with said projections of said flanges, said flanges and disks being provided with passages for the driving fluid, said passages being curved between their ends and serving to deflect said fluid in one direction at their inlet ends and in an opposite direction toward their outlet ends at a greater incline, said passages in said disks being relatively oppositely disposed to the passages in said flanges and serving to cause the fluid to pass zigzag in ogee curves.
