UNHTED' STATES GUGLIELMO ROBERTO TREMOLADA, 0F DETROIT, MICHIGAN, ASSIGNOR TO DETROIT AIR COOLED CAR COMPANY, WARE.
0F DETROIT, MICHIGAN, A CORPORATION OF DELA- PROCESS OF WELDING COPPER TO IRON.
Application led March 27, 1922. Serial No. 547,248.
T0 all whom t may concern.'
Be it known that I, GUGLIELMO ROBERTO TREMOLADA, subject of the King of Italy, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Processes of Welding Copper to Iron, and declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to a process of fusing copper to iron; the purpose being to increase the conductivity of the iron for radiating heat an object greatly desired in certain arts, as for example in the manufacture of air cooled cylinders for internal combustion enginesit will however be understood that its use is not to be confined to that art.
The advantages gained by increasing the conductivity and heat radiating surfaces of an air cooled internal combustion engine being well understood I shall illustrate and describe the process in connection with the casting of cylinders for internal combustion engines.
In carrying out my invention copper having an alloy of iron is formed into sheets from which suitable fins are shaped which are subsequently fused to the cylinder wall to form an integral part thereof.
In.the drawings accompanying this specification:
Figure l is a diagrammatic sectional view through a flask with the pattern mounted upon each side of the usual match plate showin the sand packed around the pattern in the rag.
Fi re 2 isA a similar diagrammatic sectiona view showing the flask reversed with the drag restingupon a bottom board ready for packing sand around the pattern in the cope.
Figure 3 is a diagrammatic sectional view showing the mould ready for the withdrawal of the pattern.
Figure 4 is a diagrammatic sectional view through the mould showing the core in place with a plurality of copper fins surrounding the latter lodged in the annular grooves in the mould formed by the pattern.
Figure 5 is a diagrammatic sectional View after the fluid metal has entered the mould showing the fins fused to the wall of the cylinder or casting.
Figure 6 is a sectional view on a relatively large s-cale showing a plurality of copper Vfins fused to a fragment of a cylinder wall.
Referring to lthe letters of reference placed upon the drawings:
A,'denotes a flask embodying the usual drag B and scope C; D, is a bottom board; E, is a divided pattern secured to opposite sides of the match plate E held in position by the dowel pins F, connecting the drag and cope together. G, is a core, and H denotes a plurality of rings formed of copper having an alloy of iron, lod ed4 in the annular grooves in the moul ,`their inner edges projecting into the space to be occupied by the molten metal in forming` the casting I. In making the alloy both the iron and coppler are separately heated to a fusing point. he copper is then poured on to of the iron and mixed therewith and it is then formed into flat ingots. The fiat ingots are afterwards cleaned and rolled into sheets of suitable thickness, which are then made into fins shown in the drawings. The alloy is made by adding from one to seven per cent 'of iron to the copper.
Having indicated by reference letters upon the -drawings the several elements employed in carrying my process into effect the same will be readily understood.
The mould having been properly prepared,
a plurality of copper rings containmg an alloy of iron are placed in position in the annular grooves formed in the mould with thecore in position, spaced from the inner edges of the rings. Molten iron is then poured into the mould in the usual manner and upon contacting with the inner edge of the rings fuses the latter, the rings thus becoming an integral part of the body of the casting.
Haying thus described my invention, I claim':
l. The herein described process 0f Welding copper to iron, consistin in subjecting copper containing an iron a loy to molten iron in a suitable mould, whereby the copper may be fused through the heat`of said molten metal and become an integral part of the casting formed from the iron in said mould.
2. The herein described process of welding copper to iron, consisting in supporting a copper element containing an iron alloy in iron into the cavity of said mould in contact a suitable mould, then pouring molten iron With said copper elements, to form a casting; into said mould to produce a casting and; to whereby the heat of the molten metal may fuse the copper element that it may become fuse the projecting portions of the copper elean integral part of the casting. mentsthat they may become an integral part 3.
