TUBE AND METHOD OF MAKING THE SAME.
SPECIFICATION forming part of Letters Patent No. 414,643, dated November 5, 1889. Application filed une 4, 1888. Serial No. 275,975. (No model.)
To all whom, it may concern.-
Be it known that I, W'ARREN E. HILL, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Tubes and the Method of Making the Same, of which the following is a description, reference being had to the accompanying drawings.
This invention relates to the manufacture of tubes or pipes having flanged or headed endsthat is, having laterallyprojecting flanges at either or both ends by which the tubes may be joined together or secured in place in the structure in which they are used.
Such tubes are largely used as furnace shells or flues for. steam-boilers, and I shall describe my invention as embodied in a corthat the invent-ion includes other forms of flanged tubes or pipes.
It is to be understood that in securing a flue or other like tube in a boiler structure flanges or like means must be formed between the end of the tube and the boiler-plates by which to secure the tubes to the boiler. To this end it has been customary to forge or otherwise expand one end of the tube or flue into the form of a flange, which served as a means to rivet the flue to the boiler-plates or to the front plate or plates of the furnace. It is obvious, however, that in thus forming a flange on the end of the flue the metal will be reduced in thickness, and this flanging can be practically done only for purposes where a small or narrow flange will sufiice. It is, however, desirable in many cases where flucs or tubes and pipes are used to. employ forms thereof having flanges much wider in lateral extent than would be possible to forge or ex; pand from the body of the tube without reducing the stock to such an' extent that the flange would not have the requisite strength compared with the body of the tube. Thus with boiler or furnace pipes it is desirable to form integral with the body of the flue the head or plate that is to form a' part of or is to connect it to the fire-chamber or boiler-shell.
My invention consists, therefore, first, of a headed or flanged tube or flue composed of a cylindrical body, a plateforming the head or flange provided with a circular flanged open ing, the flange of said opening being welded to the end of the cylindrical body; secondly, the invention consists in the method of producing a headed or flanged tube or fluethat is, in forming a circular flange around an opening in a plate adapted to serve as a head to the pipe and welding the flange of such opening to the end of the pipe.
In the drawings, Figure 1 is a perspective view of a corrugated tube provided with one form of flange-head shaped and j oined to the tube in conformity with my invention. Figs. 2 and 3 are detail sectional views illustrating the method of welding the head to the tube. Fig. 4 is a central longitudinal section of the tube on plane a; 1- of Fig. 5. Fig. 5 is a plan view of the structure of Fig. 4 unsectioned.
In these views, A represents the corrugated tube. It is made by forming a sheet into cylindrical form and then circumferentially corrugating the same between suitable rolls. This tube may be finished with a plain end B, Fig. 2, or with a corrugated end C, Fig. 3.
D is the flange-head of the tube, this head being usually the connecting plate or part of the structure to which the tube is to be attached. In the present instance the tube A is one of a pair of furnace-tubes which enter the combustion-chamber, the other flue and its head being indicated by dotted lines, as seen in Fig. 1. The central portion of the head-plate D is first properly cut out so as to form an opening somewhat smaller than the diameter of the flue at its inner end, or the end to which the head is to be attached.
The edge of this opening is then bent up by ter In Fig. 1 it is shown as a plain flange.
In Fig. 2 it is shown as being shaped to form a part of the last corrugation of the flue. Another flange F may be formed on this head, if requisite, by which to secure the head to other parts of the combustion-chamber or boiler. hen the head has thus been prepared, it is then welded to the flue and thereby becomes an integral part thereof. The parts to be welded together may be scarfed, so as to partiallyoverreach each other, thereby producing a lap-weld, as seen at G, Fig. 2; but the particular method of welding is not essential, as the head may be otherwise attached to the tube by various other forms of welds. duced is a much stronger structure than the flue heretofore produced and has the same lateral extent of flange or head, and it obviates all the objections incident to structures of similar shape, but having their parts riveted together.
I have hereinbefore described the invention as applied to a corrugated cylindrical flue or pipe; but I do not limit myself to such form of pipe, for these improvements are applicable to plain pipes and to pipes having other forms in cross-section.
What is claimed as new is The flanged or headed flue thus pro- 1. headed flue or tube composed of cy-
