Improvements in Elastic-Fluid Turbines, of
which the following is a specification.
This invention relates to improvements in elastic-fluid turbine-engines, and more particularly to an important modification of the structure appearing in my application concurrent herewith, this change relating to the particular formation and relation of the guidepiasslages in the nozzle and guide-passage This improvement has for its object to provide means for more readily recurving and returning the flow of steam in the guide-passages as it pas es from the buckets on one side of the bloc to the buckets on the other si e.
I accomplish the objects of my invention by the devices and means described in thefol lowing specification.
The invention is clearly defined, and pointed out in the claims.
A structure embod ing the features of my invention is clearly illiistrated in the accompanying drawings, forming a part of this specification, in which I Figure 1 is a detail transverse sectional view, full size, through the buckets, guideblocks, casing, and casing-cover, taken on a line corresponding to irregular line 2 z of Fig. 3. Fig. 2 is a similar detail sectional view,
the casing-cover being omitted and only a portiono he casing being shown, taken on a ine correspondin to line 0000 of Fig. 3 and Fig. 3 is a detail side elevation view of one of the nozzle and guide pa'ssage blocks in position in the casing, the row of buckets 4 being removed to facilitate observation. The sectional views are taken looking toward the right of Fig. 3.
Similar numerals of reference refer tdsimilar parts throughout the several views.
Referrin to the numbered parts of the drawings, t 1e casing 1 is provided with an in let-passage 7, leading to an annular chamber 8, which delivers through to a nozzle 11. Buckets 12 and 14, formed in segments 4 and 5, are retained in the web 6 of the wheel, according to the plan claimed and described by me in another concurrent application.
The nozzle 11 delivers into buckets 12 and thence, traveling through the buckets 12, enters a passage 13 near the periphery of the turbine wheel. This passa e v 13 extends transversely, inwardly, and orwardly from the bucket 12, recurving upon itself to'deliver the steam therefrom in substantially the same direction from which it was received and delivering it to the inner'side of buckets 14, whence it passes through the the outer side of the buckets into the fluidpassage 15, which passage curves upon itself and extends inwardly, forwardly, and.ltransversely to the inner line of the buckets at a point in advance of'the nozzle 11. Thence it delivers into the inner side of the buckets again, reacting outwardly at the outer side, and enters an exit-passage 1'6 and 17, from whence it. asses to an annular exhaustchamber 18 in the'casing 1 and thence out at the exhaust.
The angle of each of these passages l 3 and 15 at the point of exit of the steam from the buckets. is substantially an acute angle of twentydegrees thereto, and where the pas sage passes through the block'3 and delivers to the opposite bucket'it delivers the steam thereto at an angle of substantially twenty degrees, so that the receiving and discharge ends of these passages stand 'substantialliv; at an angle. to each other in the plane of t eir action of about forty degrees, and they are curved upon themselves, so that in their tangential action upon the turbine-wheel the current of the steam is substantially reversed or turned upon itself, so that its impact uponthe buckets tends to drive the wheels always in the same direction. Extending the assage from the outer side to the inner si e of the buckets in this way is a reat convenience in formation, asthere is p enty of room for the steam to turn without bein unduly confined, the force of the steam not iein' retarded by too sharp an angle in the gui ingpassage.
Steam has been mentioned as the actuating fluid, but it is desired to remark that any elastic fluid under pressure will serve the purbuckets, developing its force by impact and by reaction, whence it passes outwardly from pose, and I do not intend to be confined to steam merely in this turbine. i
The guide-block 3 is secured to the casing 1 by suitable screws, as shown, and is properly curved to fit in between the segments 4 and 5 exit-passage through said guide-block from. t
ing the steam directly froinTthe buckets of the turbine.
further divided into se arate ieces P P I referred, or such passages might 'fers to the part generally and not to a specific therefrom; a guide-block with a suitable pas wardly, forwardly'and transversely through part of the'opposite group of buckets; and an therein suitably curved to receive impulse from the impact of the fluid and the reaction of the turbinewlieel. The annular exhaustpassage 18 delivers out from the engine at any convenient place and receives the steam from the exit-passages 17 at intervals around the wheel, as many of the blocks 3 being made use of as the size of the turbine and power to be developed requires. The exitpassage in the case 17 receives the steam from the exhaust-passage 16 in the nozzle and guide passage block, such. passage receiv- It isdesired to remark in the matter, of modification that the block 3 of course might be made integral with the other parts of the structure, or, for that matter, it might be which might contain the passages to which I have be formed by grooves between the parts. I merely mention thisso that when I refer to segment-block it will be understood that it reintegral lock.
