Patented Apr. 15, 1930 UNITED STATES PATENT OFFICE ALLEN W. EARL, 0F CLEVELAND, OHIO, ASSIGN'OR TO THE AMERICAN STEEL AND WIRE COMPANY on NEW JERSEY METHOD OF AND APPARATUS FOR STBAIGI-ITENING ANNEALING BOXES Application filed July 21,
This invention relates to a method of and apparatusfor straightening warped anneaL ing box covers, and has for its object the provision of a novel method and apparatus for carrying out the method which will permit the quick straightening of warped annealing box covers at very low cost.
In the drawings-..
Figure l is a top plan of the apparatus of this invention.
Figure 2 is a side elevation. showing a warped annealing box cover (in section) positioned thereon, ready for straightening, and showing the cover after it has been forced down and straightened in dotted lines.
Figure 3 is a transverse sectional elevation on the line TIL-III of Figure 1.
Figure 4 is a partial sectional plan.
Referring more particularly to the drawings, the letter A designates the end support ing members of the straightening apparatus as a whole, and the letter B designates the center supporting member.
The supporting members A consist of T- shaped base plates 2, the head portion of which carries an I-beam" supporting member 3. The end faces of the I-beam supporting member 8 are beveled or inclined inwardly and upwardly and supporting channel-shaped brackets 4 are secured on the side of the web of the member 3 nearest the stem portion of the base plate 2. Angle shaped brackets 5 are secured on the opposite side web of the member 3. The brackets 4 and 5 are positioned in line with the inclined or beveled end faces of the I-beam members 3.
The central supporting member B consists of a base plate 6 on which is mounted a vertically disposed section of I beam 7 having its end faces beveled upwardly and inwardly, and angle iron brackets 8 aresecured to each side of the web portion of the I-beam 7 at both ends.
The supporting members A and B are spaced apart and longitudinally extending side anvil or straightening plates or slabs 9 are mounted edgewise on the base plates of the members A and B and tilted over so that their side faces are resting against the end 1927. Serial No. 207,478.
and are tilted inwardly so that their inner side face is supported by the beveled or inclined end faces of the side-plates or slabs 9.
The side-plates 9 and end plates 12 positioned as above described form a rectangular truncated pyramid shaped straightening or forming apparatus, having an outside dimension at its top less than the inside dimension of the warped annealing box cover, and an outside dimension at its bottom approximately the same as the straightened or unwarped annealing box cover.
In carrying out the method of this invention, the straightening apparatus described above will be assembled as above described and the annealing box cover C will be heated in a suitable furnace to a correct bending or working heat. The heated annealing box cover will then be lowered over the straightening apparatus so that the lower edges of its warped sides will be in engagement with the side-plates 9 and the lower edges of its warped ends will be in engagement with the end plates 12. Pressure will. then be applied to the annealing box cover by any suitable means to force the box cover C down over the side and end plates of the straightening apparatus and thus force the side and ends of the box cover C out into their normal straight position.
After the cover C has been forced out into normal position it is preferably left on the straightening apparatus until it cools beyond the point at which it will warp, although this step is not essential since after the cover is straightened it will not warp materially while cooling if it is removed before it is cooled.
The spacing and supporting members A and B serve to take the side thrusts developed when forcing the box cover down into straightened position, and the end thrusts are taken up by the side-plates 9, due to the end-plates 12 being mounted against the ends of the side-plates 9.
From the above it will be readily apparent that I have developed a method of and apparatus for straightening annealing box covers whereby such covers may be quickly and cheaply straightened, thereby maintaining such covers in better shape at all times and greatly increasing the life of such covers.
I claim- 1. The method of strai htening warped anm nealing box covers, whic consists in providing a rigid base having upwardly extending and inwardly inclined side and end walls, said walls having an outside dimension at the bottom substantially the same as the inside 15 dimension of the unwarped annealing box covers, an outside dimension at the top of less than the inside dimension of the warped annealing box covers, heating said warped covers, positioning said covers over the upper end of said base, applying pressure to the top of said cover to force said cover down over said base, and then permitting said cover to cool While on said base to prevent rewarping during the cooling thereof.
2. A straightener for annealing box covers comprising a supporting structure having upwardly extending and inwardly inclined supporting faces, a pair of straighteningplates mounted on said supporting structure and ina clined against said su porting faces said plates having their end faces beveled upwardly and inwardly, and a second pair of straightening plates mounted against the end faces of said first named plates.
8- 3. A straightener for annealing box covers comprising a plurality of spaced supporting members, each of said members comprising a base plate, an I-beam secured to said base plate and having its end faces beveled upwatdly and inwardly, a pair of side straightening plates supported against said beveled end faces of said I-beams on said supporting members, said side-plates having their end faces beveled upwardly and inwardly, and
end plates overlying and supported against the beveled end faces of said side-plates, thereby forming a truncated pyramid-like straightening and forming anvil.
In testimony whereof, I have hereunto 60 signed my name.
ALLEN W. EARL.
