To (tZZ whom it may concern:

Be it known that 1, MAX ROTTER, a citizen in the county of Milwaukee and State of Wis- Improvements in Steam T urbines, or which the following is a specification.

My invention relates to elastic-fluid turbines, and more articularl to means for preventing the on s of the bathing-ring from getting out of alinement.

It is old to provide the ends of the vanes and blades of steam-turbines with a bafflingring; but it is sometimes found impractical to secure the two ends of the ring rigidly together by reason of the expansion and contraction which it undergoes,- due to changes in temperature of the, ring itself and of the vanes and blades; but it is found to be of the ggeatest importance that the ends of the V the end of one of the sections of any ring be- 9 is a plan view there I come displaced sufficiently to catch into the adjacent parts while rotating at a very high rate of speed a great amount of damage would ensue, possibly to the extent of ruining the entire machine. signed to obviate any mishap of this kind, and through its use it is practically impossible for the ends of the sections to get out of alinement.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a structure embodying one form of my invention. Fig. 2 is a plan view thereof. Fi 3 is a erspective view of the right end of t e ring 510?). in Figs. 1' and 2. Fig. 4 is a side elevation of a structure embodying a modified form. Fig. 5 is apla'n view thereof. Fig. 6 is a plan view of the left end as detached. Fig. 7 is a perspective of the right end as detached. Fig. 8 is a section through a ring embodying another modification, and

y invention consists in providing oneend of each section of the bafliing-ring or morestrips, whiqh; may be integral thereor ri 1dl secured thereto, and these strips over ie t e opposite end ofithe baffljnge ring and'\ fit .a ainst theinner sides of the flanges on the ing; so as to prevent any lateral displacem'ent' of either end. It is evident that this is equally as'applicable to rag Eipecification of Letters Patent. Application filed April A1906. Serial No. 810,427.

In Figs. 1, 2, and 3 of the drawings I have" 1 shown one 'form which my invention may assume, while Figs. 4 to? illustrate a slightlydiiferent form. The bafiin usually'inade up of two, or more sections, is. preferably channel-shaped in cross-section,

aving-flanges 1 and a' web portion 2, to which the vanes or blades 3 are secured in any suitable manner, preferably by rivetin their ends in 0 web of the battling-ring. the central portion of the web are cut away for a short distance back from the end, thus leaving two strips or tongues 5 5, which are oflset to overlap the web of the op osite end and fit against theinner sides of tlib 'flanges, thus allowing for free longitudinal movement, but preventing any lateral movement of the parts in respect to each other. he strips'or to es may be oflset at a slight distance ba di of the line on whichthe fia ter portion of the web are out o as clearly shown in Fig. ,3, in which case the opposite end may. be out off ,flush, or the The flanges 1 and emngs 4, provided in the g-ring, which is and oenstrips ortongues may be oflset on'the line on which the other arts are cut away, as shown in Fig. 7, in w 'ch case the opposite end mustbe cut or chamfered, as shown in that a flush joint maybe formed.

A third form is shown-inFi s. 8 and 9, in which the strips 5 5, instead of being integral with the baflling-ring; are. separate and brazed or secured in any suitable manner to one end of it. By providing two strips either integral with or secured to than a single one of the full Fig. 6, in order theF-r' rather width b i the web there s no interference with the riveted en ds of the vanes or blades and the stripsmay lie fiat on the bottom otthe web in the-same ent outward or otherwise flanges should'wear down to the level of. the
