THOMAS S. EVANS AND EDWIN H. BISSET'I, OF WINNIPEG, MANITOBA, CANADA.
STOVE-PIPE ELBOW.
SPECIFICATION forming part of Letters Patent No. 313,858, dated lwflarch 17, 1885.
Application filed September 20, 11184. (No model.)
To an whom it may concern.- I
Be it known that we, THoMAs S. EVANS and EDWIN H. BIssETT, both of Winnipeg, in the Province of Manitoba, in the Dominion of Canada, have jointly invented certain new and useful Improvements in Stove-Pipe Elbows; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, in which- Figure lis an elevation of our improved elbow, a portion broken away to show the internal crimps; and Fig. 2 is an enlarged section of one of the crimps.
Our invention relates to a corrugated elbow in which the crimps are formed on the inside of the pipe, so as to present a smooth outside surface on the lesser arc; and our invention has for its object to facilitate the manufacture and allow of a low quality of iron being used.
Our invention consists in flattening the crimped material equally on both sides of the crimped seam, whereby the flattened material will cover the seam and increase its strength.
A is our improved elbow, formed of one piece of sheet metal by graduated or tapering crimps B, the surplus metal thrown inwardly from the side edges of the plate to form the lesser arc. These criinps are raised on the interior face of the plate and flattened, so that L the surplus metal will be distributed equally on both sides of each seam D and cover the same, to increase the strength of the elbow and permit it to be manufactured in a finished state by machinery, without requiring the use of a hammer and mandrel to flatten the pointed end of the crimp against the shell.
We are aware that it is not new with us to crimp the material on the inside of the elbow on the lesser are, and we make no claim for the same.
We claim as our invention Asheet-inetal elbow crimped on the inside, having the surplus metal of the crimps distributed on both sides of the seam and fiattened over the joint, as set forth.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
THO. S. EVANS. EDWIN H. BISSETT. XVitnesses:
JAMES BIssETT, ANDREW MONALLY.
