REENFORCEMENT FOR WELDED SEAMS.
Application filed May 13, '1922, Serial No. 560,671. Renewed February 23, 1928.
My invention relates to thc art of uniting ply plays in advantageous part in the holdthe edges of metal sheets one with the other n:: of the :irch brick usually associated with by means of eutogenous welds. That is, thernic siphons in locomotive fireboxes. In through the agency of the fusing of said each of the sectional figures there will be ob- 5 edges and the progressve addition of a molserved a V-'weld, 2, which is made either by ten metal of much the same nature as the the electric or oXy-acetylene autogenous weldsheets to be united. As is well known, autoging process. It is this welding which is to enous'welded seems in boler sheets and the be reenforced in each case. For the reenlike,' while often developing a strength and 'forcenent of the weld?, I employ a sinuous 10 durability exceeding th t th f a i t d metal rod 3, preferably of rectangular cross seam, in one or the other common forms, section and of less width than height. This cannot be relied upon as a scam of constant sinuous section is first conforned to the running strength or of constant ductility or curved or flat surface of the united sheets eshock resisting strength. In consequence, it (for c'onparison see Figs. 1 and 3) and is 15 is not the practice to use autogenously welded laid fiat against the naked surfaces of the seams in places where they are subjected to shcets. The undulations or bends of the rod tensile strains or heavy Shock stresses. The' 3 are deep enough' to reach far to one side characteristc lacking is that of assured and the other of the weld 2 so that 'naked surstrength in -o rti t th ro s ti n f iacest of the sheets are' exposed in the bends.
20 the given weld and the materials employed in Upon these sur-faces' and the inner surfaces making it. v of the rod 3 1 apply welding material by the Th bj t f my i e ti i t reenautogenous process and thus build up abutforce welded'seans as to render them de ments united With therod and, obviously, sitpendable in all respects, and further, one uatcd on both sides of the weld 2. In this '25 object of this invention is to provide a reenmanner the edges of the sheets, in addition to forced autogenously welded seam which, if being united with the weld 2, are laced toneed be, may safely be used in places which gether by the sinuous rod 3. are directly exposed to' firebox flames. My Having secured the sinuous rod in the deinVentiOn will be found to be of'particular scribed relation, I then preferably proceed sl 30 importance in the art of making boilers, With the ad dition of welding material until wherein the seems 'are subjected to heavy llof the outstanding surfaces of the rod are pressures and strains, but obviously is applilmbedded in welding material 5, as best cable throughout the metallurgcal arts own in Fig. 5.
- wherever welded seems require reenforce- It is apparent that as the engaging sur- 35 ment. faces 'of the abutted sheets and the sinuous 'The invention will be readily understood rod respectively, are not w'eldedtogether, on reference to the accompanying drawings, there must necessarily be a thin air filled in which Fig. 1 is a cross section of a metal space or gap between them, conforming to tube or cylinder welded and reeuforced in the bends and connecting portions of the 10 accordanee with this invention; Fig. 2 is a sinuous .rod. However such a gap is SO side view thereof; Fig. 3 is a vertical section small relative to one formed by a straight of a boiler water wall or water leg presenting lapping strip having the same lateral reach' a reenforced welded seam; Fig. 4 is a side -fromone side to the other of the weld 2 asin iew tliereof;'Fig. 5 is a like View showing no appreciable manner to interfere with the the reenforcing weld completed and illustrattransmission of heat. It will be undering a different spucing of the stay-bolts; Fig. stood that if the rod were,of greater width G is'a horizontal section showing how the the extent of the air ga would be increased.

The rod 3 in each case may be the showing how the reenforcement which I apsame or of better material than that composa I I 'mesme ing the sheets which are welded together, sinuos bar dsposed inflat engagement with and, as will be apparent, the whole strength parts of said plateportions and crossing and of the laced or reenforcing bar or 'od is posirecrossing said seam and being embeddedin 3 tively' added to the strength of the'autogwelding material upon said marginal plate* 5 enonsly welded seam; i r portions and said seem. v
