WILLIAM M. SMITH, OF TURTLE CREEK, PENNSYLVANIA.

POWER GENERATOR.

Original application filed September 4, 1925, Serial No. 54,492. Divided and this application filed June 2, 1926. Serial No. 113,301.

This invention relates to certain new and use iiil improvements in power generators and the present invention particularly has for its object to provide certain improve5 raents in the motor used in such power generators. _ .

The present invention relates to that class of power generators in which is provided a stack and a motor located on a vertical lo axis within the stack operated by the passage of air through the stack, and the present application is a division of my application filed September 4, 1925, Serial No. 54,492.

In its general nature the present invention js resides in the provision of an improved motor consisting of a series of open ended cylinders located on a sectional shaft within the stack and having internal and external vanes by which the cylinders are turned to 20 impart their rotation, to the shaft;

In its more detailed nature the invention resides in those novel features of construction, combination and arrangement of parts, al] of which will be first fully described, then 25. lie specifically pointed out in the appended claims, reference being had to the accom.panying .drawings, in which:.

Figure '1 is a view in elevation of a stack with my improved motor located in the same. ;w Figure 2 is an enlarged detail vertical longitudinal section and part elevation of one of the motor units.

Figure 3 is a detail horizontal section on the line 3—3 of Figure 2.

In the drawings like numerals of reference indicate like parts in all the figures and the same numerals of reference are employed for the same parts as are employed in my original application aforesaid. This is done 40 for convenience of cross referencing.

In the drawings 30 and 31 represent the steel supports for the stack 15 which, is mounted on the hollow base. 16, from which base , the -air passes, up through the stack 45 15. As the construction of the,stack, the base, and the means for accelerating the air passage through the stack constitutes no part of this application further, description thereof is thought to. be unnecessary.

Referring more particularly to Figure d it will be seen that the motor consists of a series of. open ended cylinders 29 each having a spiral vane 28 secured to the outer wall and a spiral vane 45 secured by means 55 of _a flange 46 to the inner wall. The vanes and 45 are so arranged that they appear to form a single spiral connected with a vertical shaft 47, and the vanes are provided with a plurality of corrugations 48 located transversely of the vanes in order to present CO a more effective surface to the air circulating through the cylinder 29 and the stack. 15. The inner edges of the vanes 45 are spaced slightly from the shaft 47 while the outer .edges of the vanes 28 are spaced slightly θδ from the inner wall of the stack 15.

The cylinders 29 and likewise the vanes 28 and 45 are connected to the shaft 47 by means of radially disposed rods 49 having their inner ends secured to sleeves 50 which are rigid 70 with the shaft 47 while their outer ends are secured in any approved manner in bosses 51 formed upon the inner Avail of the cylinders 29. The rods 49 are carried in spaced relation with each other along the inner wall 75 of each cylinder 29, certain of the rods being located in planes which are at right angles to the planes passing through the other rods.

The shafts 47, as are the cylinders 29, are formed in sections and are connected to- so gether at their adjacent aligned ends 52 and 53 by means of bolts 54. The end'52 ,is hollow as shown and is adapted to receive the reduced portion 55 of the upper end of a second aligned section of the shaft. This 85 reduced end is provided with elongated slots 56 where the bolts 54 pass through the connected ends of the shafts so that the ends of the shafts may be moved towards each other in case, of wear. 90

The upper end of each section 52 of the combined shaft passes through a bearing 57 and is secured at 58 to said bearing. Said bearing is supported in a flanged race 59 and a plurality of rollers 60 and 61 are 95 adapted to aid. in the elimination of friction between the parts. The race 59 is carried by the horizontal beams 36 and 37 so that each individual cylinder 29 together with its vanes 28 and 45 and section 47 of the shaft lop is , supported entirely by the hearings 57 and the race 59, and each of these bearings is carried at spaced points along the vertical stack 15 by means of a spider f ormed of eye beams 36 and .37. At the central portion 1U5. of each, web and where the beams 36 and 37 are, connected together is provided a hollow boss 62 through which a section 47 of a shaft is passed and adjacent the bearing 57. , ' . &lt; uc

As shown doors 34 are located adjacent the beams 36 and 37 in the stack and adjacent the bearings 57 so that when desired the bearings may be inspected and repaired 5 without any inconvenience.

At the extreme lower end of the shaft 47 which projects into the hollow base member 16 there is provided a gear 63 from which power can be taken in any desired way as io for instance the manner shown in Figure 2 of my original application, but as such specific mechanism for taking off the power constitutes no part of the present application further disclosure thereof in this case is 15 thought to be unnecessary.

The operation of my device is as follows: A circulation of air is maintained in the stack 15 from the hollow base to the upper extreme end. The air passing upwardly so through the stack 15 impinges upon the spiral blades and causes a rapid rotation of the cylinders 29. The corrugated blades together . with the close association of these blades with the shaft 47 and the inner wall -5 of the'stack 15 will aid in maintaining a predetermined air pressure in the stack for the most efficient operation of the motors.

The topmost section of the shaft. 47 is journalled in the bearing box 75 in which are so located roller bearings 76 and a ball bearing 77., the ball bearing Toeing mounted upon the reduced end 78 of the shaft. The bearingbox is carried by a spider 79 secured to the top of the stack 15.

o> From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be clear to those skilled in the art to which it relates.
