M. J. OMEARA. ANNEALING POT.
No. 595,494. Patented Dec. 14,1897.
UNITED STATES PATENT OFF CE.
MICHAEL J. OMEARA, OF ANDERSON, INDIANA.
ANNEALlNG-POT.
SPECIFICATION forming part of Letters Patent No. 595,494, dated December 14, 1897.
Application filed March 2 5, 1 8 9 7.
To all whom it may concern;
Be it known that I, MICHAEL J. OMEARA, a citizen of the United States, and a resident of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Annealing-Pots; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying-drawings, which form a part of this specification.
My invention relates to an annealing-pot for annealing metal, especially tin-plate; and its object is to provide an improved construction of the same which shall possess superior advantages with respect to efficiency in use.
The invention consists, essentially, of an annealing-pot composed of a metal plate bent upwardly at each end at approximately right angles, forming the bottom and two sides and two end rectangular plates, the side and bottom edges of which are formed with tongues and grooves which engage with corresponding tongues and grooves of the end plates and said tongues clenched down upon the outsides of said plates and welded thereto, as hereinafter fully described and claimed.
In the accompanying drawings, Figure l is a perspective View of an annealing-pot complete, showing the same inverted. Fig. 2 is a detail perspective view showing the tongues before being clenched and welded. Fig. 3 is a similar View showing a portion of the center plate and one of the end plates disconnected from each other.
7 In the said drawings the reference-nu meral l designates the center plate, having the ends bent at approximately right angles, forming the bottom 2 and sides 3 of the pot. The vertical edges of said sides and the edges of said bottom are formed with a number of alternating rectangular slots or mortises and corresponding tongues 5.
The numeral 6 designates the end plates of the pot, which are rectangular in form and the side and bottom edges formed with slots or mortises 8 and tongues 7, corresponding Serial No. 629,191. (No model.)
with the mortises and tongues of said plate 1. The said tongues are of such a length with respect to the mortises that when engaged therewith they will project beyond the plates, as seen in Fig. 2.
In assembling the parts the tongues and mortises of the end plates are engaged with those of the center plate and the tongues then clenched down and welded, causing the metal of the same to overlap the edges of the mortises and thus making the end plates practically integral with the center plates.
An annealing-pot constructed as described is practically indestructible, as the joints Will not become loose by any temperature to which they may be exposed or by any rough usage to which such articles are usually subjected.
I am aware that it is not new to make a joint by forming two metal plates with alternating tongues and mortises, which tongues project through the mortises beyond the plates and have their ends bent down at right angles thereto. In my invention the tongues after being passed through the mortises have their sides hammered down and Welded to the plates, so as to overlap the edges of the mortises.
Having thus fully described my invention, what I claim is As an improved article, an annealing-pot, consisting of the central plate having its ends bent upward at approximately right angles, and the side and bottom edges formed with alternating tongues and mortises, and the rectangular end plates having coinciding tongues and mortises engaging therewith and the tongues projecting through the mortises beyond the plates and having the corners swaged down overlapping the sides of the mortises and welded to the plates, substantially as described.
In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
MICHAEL J. OMEARA.

B. H. CAMPBELL, PETER LA BELLE.
