Specification of Letters Patent.
, Patented May 1351913.
To all 'wlmm it may concern v Be iti known that I; 'GEORGE W'Esfrmo- HOUSE, a citizen'of-the United States, and a resident of Pittsburgh, in .the county of Allegheny and State'o'f Pennsylvania, have made a newand useful-Invention in Bladesf and Means for- Mounting Blades of which.-
- the following is a Specification.
My invention relates to blading andparticula-rly to turbine blading,- k An object of my invention is to produce a new and improved blading and also new and I improved means for assembling and mountin'gblades. w
. These and other-objects I attain by means of the blades and bIading illustrated inthe drawings accompanying.thisapplication and.
- forming a part thereof.-
In the" drawings, Figure l is a'perspective -viewof bladingembodyin'g my Invention shown; in connection With'a' portion .ofa 'blademoimting elementj. Figs; 2. and 3 are.
invention; I group'of blades taken alongthe longltud mal perspective views-of blades embody ng my Fig, 4 is atransverse section of a axes of the blades and illustratesa modifica f tio'n'ofmy invention.
. For'convenienceof' descripti'bn, -I have illustrated my invention m'connection with bla'des adaptedto be employed-in a turbine,
in which motive. fluid is delivered to a row of blades, 'andafter having traversed the of turbine,
blades isre-directedtan d re-delivered to the "blades: I do not desire to limitthe ap plication of myinventipn to blades for thls type nor to the arrangement. or. con
struction' illustrated, .andI desire-it to be 'understood that the drawingsar'e merely tee- 1mm:-
illus'trative-and' that various changes and modifieationsimay be made wlthout departthesplrit andscope of my inven- Referring a5 the drawi ngsf'each blade illustrated 6. The body portion islsubstantially cres-.--'
consists of a body portion 4", a" mounting portion 5-,.and a shroudin'g flange I cent shaped in cross section, being'provided; on one side Witconcave .workmg face-"7 v i and on the other side with a' convex working face 8. The oonjv'iex face i's divided into two portions by an intermediate spacing piece 9,, I which is formed integrally with the body portion of-the blade and which is provided with a convex face 10 adapted to en age the concave face oithe next adjacent bla again;
the blades are assembled n a. row.
. face of the operate with the flanges 6 of all the-other through the body portion of-theblades and assembled on the.
formed by axially with tween the mounting 1 tongue 14 isadapted to. fit-snugly into a slot ,15' formed in a mounting element 16, andeach blade is 'rigidly' and positivel secured a of rivets 17, which n versely extending}holes 18 provided'.' in the .tonguel of each blade and gistering holes 1 [-19 provided in the blade mQlIIIiGLDF The over-portlqnso v shrouding flange 6 provided at theend of each blade projects laterally beyond the convex face of the blade in the same'direct-ion I as the spacingpiece 95 and is provided" with a convex edgeadapted to engage the concave next'adjacent blade and to 00- blades to form a shroud forthe row ofhlades' whenithe blades are assembled in a row.
I contemplate assembling the bladesinto short segments prior to mounting-them on the'blade carry-fngelement, and 'to thisend I provide holes 11, which extend transversely the intermediate spacing pi'eces 9. I then assemblei several blades ton a binding member or pin12, which are shaped and'extends" through'th'e holes 11 in the blades. Th-Ipins 12 fit snugly into the holes 11 and are so arrangedjth'at' theseparate segments-may be -lblade: mount ng element.v into anorgamzed row, 'in'which thepins 1 2 all codperate. to hold the blades in placeand to laterally strengthen-the row ofiblades, I accomplish this byso arranging the ins mt-hat: they project beyond thel'ast bla eof s m nt at one end of the Se ment and dO'IlOt extnd'entirely throu h the final bladeat theother end of the segment. With this arrangementthe 1 projecting end ofthe pin of one segment extends into the:
hole..l 1 ofthe adjacent blade of the next; segment when thesegments are assembled in an annularrow. 1
The mounting portion 5 ofieach blade is Y piece of metal, the spacl'ng piece9 and the base portion fi-being the -,milling operation. The mounting portion consists of a shoulder 13 and-a narrow-tongue 14.-which projects'coj the body portion'ofthe blade. 'The'shoulder'i13-is soiiconstru'cted that it co; operates with the concave face. of I the next jacent blade andiiorms a spacing piece be ends of the blades, The
