TUBBINE.

l'.lhe obj t of mi invention is to construct'.y a turbine in whic the motive iiuid is admitted at one end of the cylinder of the tur- 'of one of the driving bine and distributed to a pluralit of drivin wheels in such a manner that t e motive duid is utilized to its fullest extent in the rotation of the said driving wheels.

n A. further object of my invention is to rovide -ak suitable receiving-chest into` w ich the motive fluid is lirst admitted.

A further object of m invention is to provide suitable means or directing the motive fluid from-the receiving-chest tothe driving wheels. Y

A further object of my inventionis in the improved construction of the distributers an in the construction of the blades upon the driving wheels.

These together with various other novel features of construction and organization of the several part-s constitute my invention.

lln the accompan 'ing drawings: Figure 1 is a central vertica section through my improved turbine; Fi 2 is a transverse section taken on line 2-2 ig. 1, showing the receivin -chest and receiving chest distributer; F1gs.3 and 4 are detail views in elevation of the nozzle used' in the receiving-chest-distribliter; Fig. 5 is a side elevation of one ofthe drivinwheel distributers, drawn on a larger scale; ig. 6 is a face view of the distributer as shown in Fig. 5, and showing a face view wheels; Fig. 7 is a face view of the driving wheel as shown in Fig. 6; and, Fig. 8 is a perspective view of one of the blades of the driving .wheel de tached. y s

Referring to the drawings, in Which-like references indicate likeparts 1 represents the shaft of a turbine rotatab y mounted in suitable bearings 2 and 3. Said shaft 1 is provided withannular collars 4 which fit Specification o! Letters Patent. l PatentedMay' 17, Application med August 2, 1909. Seria1\No. 510,837.

into recesses formed in sleeves 5, secured in the said bearings 2 and 3,'Which hold the shaft against any longitudinal thrust and v said bearings are provided with `annular spaces 6 for cooling the bearin s by the circula-tion'of water. Between t e said bearings 2 and 3 is located the cylinder 8 havin heads 10 and 12 which are rigidly secure to flanges formed upon said bearings 2 and v3. The said shaft 1 extends through the center of said cylinder 8 and is provided with a plurality of drivin wheels 14 to 22 which are secured to said s aft by a key 25.

A receivin -chest 26 is located at one end of the cylin er 8. The said receiving-chest` I may be formed in the cylinder but the construction shown in the drawing is preferable, in which the said receiving-chest is secured between the end of the cylinder 8 and the head 10. The receiving-chest 26 is provided with an inlet port 27, shown in Fig. 2, which communicates with the chamber or recess 28 formed around the greater ortion of thel inner surface of. the receivin chest. Said recess 28 terminates before it reaches the inlet ort 27. The portion 29 of thev receiving-c est forms a stop `which closes the end of the Vrecess 28.

A circular receivin chest-distributer 30 is tightly fitted into t e receiving-chest 26 and is rigidly held therein by a key 31. The receiving-chest-distributer 30 completes the chamber formed by the recess 28 in said receiving-chest 26, into which chamber the motive fluid is admitted through the said inlet jtion has been found to be the most eiicient means for conveying the motive uid to the The outer surface of thedriving wheels. nozzle is madeslightly conical as is also the apertures in the receiving-chest-distributer,

which permits the nozzle to be driven tightly into its proper position and also prevents the possibility of the nozzle being forced -through the said aperture and striking the buckets of the driving Wheel. The ends of said-nozzles are beveled so that they will be flush with the surfaces of the receiving-chestdistributers The driving'wheels 'are provided with buckets 35, clearly shown in Fig. 8. .Said bucketsy are constructed of a plate which 1s -struck up to form blades 36 and 37, the fordriving wheel in any suitable manner.

Distributers 40 to 46, shown drawn on a larger scale in Figs. 5 and 6, are placed be tween the driving wheels. Said distributers are ri idly secured in the cylinder 8 and each distriuter is providedwith a central opening which ermits the distributers to encircle the hubs of) the driving wheels, which allows the latter to turn freely while the -distributers remain stationary.

The distributers are provided with grooves or passageways formed in the periphery of the same. Said grooves extend t o a depth equal to the height of the buckets uponthe driving wheels, said grooves are larger at the inlet lside and narrower at the outlet side of said distributer and said grooves are set at an angle to the axis of said distributer so that the motive fluid will be collected from one driving wheel and directed to the next adjoining driving wheel at such an angle that the' greatest force of the motive fluid will be exerted upon the driving wheels and most e'ectively rotate the latter.

The cylinder is provided with an exhaust outlet pipe 51 and said cylinder is larger in diameter at the exhaust end and the distributers and driving wheels gradually increase in diameter so that the motive fluid will be permitted to expand.

The operation of my invention is as follows: Steam or any other suitable motive fluid is admitted under pressure, through the inlet port to the receivin -chest, from which it is directed by means o a plurality of nozzles conveniently spaced around the circumference of the receiving-chest-distributer. Said nozzles direct the motive fluid against the blades of a driving Wheel 14 located adjacent to the said receiving-chest-distributer, the motive fluid after rotating the driving wheel 14 and the shaft to which the latter is keyed, passes through the grooves or passageways formed in the distributer 40 located between the driving wheels 14 and 15. $5

Said distributer 40 directs the motive fluid to the second driving Wheel 41 a ainst the buckets of which the force of t e motive fluid is exerted. The motive fluid thus acts upon the several driving Wheels between each of which is placed a'stationary distributer to collect the motive Huid and direct :the number of the 'distributers and the bucket wheels and in the arrangement of the several parts without departing from my invention. i

Having thus desciibed my invention I claim and desire to secure by Letters Patent:
