To ALL WHOM 1T MAY CONCERN: I v
Be it known that I, C. HOLLEB, of Cincinnati, inl the county of Hamilton, nd Stete of' Ohio, have invented a. new and useful Improvement v in Elbows; for StovePipe s, of which'theffollowingA isa fullland cleardescription, referencebeing'hadtothe accompanying drawings, making part of this spcification.
The nature offmy invention consists in formingthe elbow of one piece of 'sheet metal, having the interior curved surface corrugated, andlthe exterior curvedsurface smooth n I i Figure 1 is a. perspective view of-my vimproved elbow for stove-pipes. Figure 2 is a. longitudinl'section of the' same. l f Y. A. is the elbow, shaped to connect-pipes' which areat right angles to each other. The interiorcurv'ed sui'- face, B, is corrugated, while the ex'teriorf srface, C, is smooth. The corrugations extend radially from the centre lof' curvature ofjlthe elbow over 'abot one-half-of the curved surface of the elbow, gadually'decresng in depth towards theexteriorfsrface, Y l a Ia are rivets, of fihi-"eli` two"or more are n sed, for securing'rthejap" at each end of the elbow. They're secured in place be'fore the elbowis formed.' Intermediate rivets mgyb'e inserted in the -.lap, between'extreme rivets a a. I' v When the elbow is constructed,othe inner s urface,vhaving asmaller radius of curvature, is buckled-or co'rrugeted. v l A Y l I vMuch time is saved in this construction of elbow`s,-over the mode no w. employed, byvmeans of crimping together series of cylindricel sections of sheet metal.V In my improved elbow, but o ne piecev ofmetal is used.
What -I claim as new, and desire to secure byLetters Patent, as a new article of manufacture,'is.
The elbow for stove-pipes, constructed as herein shown and described. g
