TURBINE.

Specification of Letters Patent.

Patented a 2c, 1915.

Application filed July 6, 1914. Serial No. 849,319.

To all whom it may concern:

Be it known that 1, DAVID VVEsTrALL, a citizen of the United States, residing at Canajoharie, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Turbine-Engines, of which the following is a specification.

This invention relates to an improved turbine engine and one object of the invention is to provide a turbine engine whlch is so constructed that it may be caused to rotate in whichever direction desired by simply opening and closing certain valves in the supply and draw off pipes.

Another object of the invention is to provide the turbine of the engine with an improved construction so that the steam or other operating medium passing 1nto the turbine will be caused to move rapldly through the same and at the same time rapidly rotate the turbine and shaft upon which the turbine is mounted.

Another object of the invention is to provide improved standards for rotatably mounting the shaft of the turbine engine, the standards having their upper ends formed into improved bearings through which the shaft passes.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the turb1ne engine principally in vertical longitudinal section, certain portions of the same being shown in elevation, Fig. 2 is a vertical transverse sectional view taken along the line 22 of Fig. 1; and Fig. 3 is a vertical transverse sectional view taken along the line 3-3 of Fig. 1.

The shaft 10 is rotatably mounted in the bearings 11 and 12 of the supporting standards 13 and 1 1 and is provided with longitudinally extending passages 15 and 16 having their inlet and outlet arms 17 and 18 extending from the ends of the passages 15 and 16 to the side of the shaft 10 as clearly shown in Fig. 1. The arms 17 communicate with the chambers 19 and 20 formed in the bearings 11 and 12 and the arms 18 communicate with the interior of the turbine for a purpose which will be hereinafter brought out. Feed pipes 21 and 22 communicate with the chambers 19 and 20 and exhaust pipes 23 and 24 lead from the chambers 19 and 20 so that the steam entering the chambers may be drawn ofl and thus the turbine caused to work properly. In order to control the feed pipes and exhaust pipes there has been provided valves 25 of the hand-operated type. It is necessary that the steam should not escape from the chambers 19 and 20 around the shaft 10 and therefore the bearings 11 and 12 are provided with packings 26 similar to those placed about the propeller shaft of a boat.

The turbine is carried by the shaft 10 between the standards 13 and 14 and is provided with a drum 27 which has its ends closed by the heads 28 which are secured to the side flanges 29 of the drum 2'? by means of bolts 30. This drum is provided with a hub 31 from which there extends webs 32 which are in the form of disks and extend from the hub 31 to the wall 33. This wall 33 is an annular wall extending entirely about the drum and forming a chamber between the wall 33 and the outer wall of the drum as clearly shown in Fig. 1. Within this chamber there is provided partitions 3a which divide the chamber into a plurality of tracks 35 which are in their turn provided with perforated abutment plates 36. Openings 37 are provided so that steam may pass from one track 35 into the other and thus move about the drum in a spiral course. Between the heads 28 and the outer disks 32- there is provided annular bands or partitions 38 which divide the space between the heads 28 and outer disks 32 into the chambers 39 and 40 separated by spaces 11 and 42.

When it is desired to have the turbine turned in one direction the valve or feed pipe 21 is opened and the valve of exhaust pipe 24 is also opened. This will cause steam or any other suitable medium such as compressed air or the like to pass into the chamber 19 and through the passage 15 into the chamber 39 with which its arm 18 communicates. The steam will then engage the perforated abutment plates 4-3 and after passing through the openings formed therein will enter the conduit 44: into the chamber 40. It will then engage the perforated abutments 4:5 and after passing through the openings formed therein will pass through the conduit 46 into the track 35. The steam will then pass through the track 35 and when it reaches the opposite side of the turbine will pass through the chambers and conduits at the right-hand side of the turbine in Fig. 1 back of the chamber 39 and n h A.

into the arm v18 of the passage 16. The

steam will then pass into the chamber 20 and into the exhaust pipe 24:. As the steam is traveling through the turbine it will r0- tate the turbine by striking the abutment plates and will cause the turbine to rotate rapidly. If it is desired to have the turbine rotate in the opposite direction the valves of pipes 21 and 24 will be closed and the valves of pipes 22'and 23 will be opened. The steam will then pass through the turbine in the opposite direction thus causing the turbine to rotate in the opposite direction from which it did previously. lhe rotation of the turbine can therefore be easily controlled and the speed of rotation can also be controlled by opening the valves of the inlet and exhaust pipes the necessary amount to place the desired amount of pressure upon the abutment plates. It will therefore be seen that a turbine engine has been provided which is comparatively simple in construction but which is so constructed that the direction of rotation may be controlled and also its speed controlled.

What is claimed is t 1. A turbineengine comprising standards having their upper ends provided with bearings having chambers formed therein, feed pipes and exhaust pipes communicating with said chambers, a shaft rotatably mounted in said bearings and provided with passages leading from said chambers and having their opposite ends terminating at points intermediate said standards, a turbine drum carried by said shaft intermediate said standards and inclosing the inner end portions of the passages formed in said shaft, partitions positioned in said drum dividing the end portions into annular tracks having conduits connecting the same and dividing the intermediate portion of the drum into a spiral track communicating with the chambers in the end portions of the drum and perforated abutments positioned in said chambers and tracks.

2. A. turbine engine comprising a rotata- Gopies of this patent may'be obtained for five cents each, by addressing the Commissioner of Patents, i i 7 bly mounted shaft provided with passages having their inner ends terminating adjacent the central portion of the shaft, a feed pipe communicating with'one of the passages of said shaft, an exhaust pipe com municating with the second passage of said shaft, and a turbine rigidly carried intermediate its length and inclosing the inner end portions of the passages of said shaft, the end portions of said turbine being'provided with annular partitions forming annular chambers having conduits connecting the same, and the intermediate portion of the drum being provided with partitions forming a spiral. track connecting the outer chambers of the end portions of said drum;

3. A turbine drum, heads for said drum, a hub for said drum, disksleading from said hub to the walls of said drum, an inner wall positioned adjacent the outer wall of said drum partitions positioned in the space be v tween said inner and outer walls and form ing a spiral track about said drum, abutments positioned in said track, partitions positioned in the space between said heads and the outer disks leading'from said hub to thewall vof said drum and dividing the space between said heads and outer disks into annular chambers, abutments positioned in said chambers, and conduits providing communication between said chambers.

4. A turbine drum, partitions in said drum dividing the end portions of the drum into annular chambers havingconduits permitting communication between said chambers and dividing'the intermediate portion ,of said drum into a spiral track leading from the outer chamber at one end'of said drum to the outer chamber at the opposite end of said drum, and abutments positioned in said chambers and track.

In testimony whereof I afiiX my signature in presence of two witnesses.
