Description
BENJAMIN D. STEVENS, OF DEOORAH, IOWA, ASSIGNOR TO HIMSELF AND CHARLES GILL, OF IIXE'IER, NEW HAMPSHIRE.
Letters Pat/mt 1Y0. 66,411, dated July 2, 1867.
IMPROVBD MACHINE FORI'ORMING SHEET-METAL PANSa TO ALL WHOM IT MAY OONGERN: l l 4 Beit known that I, BENJAMIN D STEVENS, of Decorah', in the county of Winneshek, and State of Iowa, have invented an Improved Machine for Forming Bake-Pans, and other sheetmetal vessels of rectangular form; and I do hereby declare that the following ist/a full and exact description thereof, reference being had to the accompanying drawings,making part of this specification@ l Figure 1 being a top view of the niahine spread'open ready for use. l
Figure 2, a cross-section, showing/the position of parts when the sheetfrnetal is inserted ready to bend, and also after the bending is accomplished.
Like letters designate corresponding parts in both ofthe iigures.
The machine has a central supporting-bar or bed-piece, B, which is secured to the bench of the workman. On one edge, is hinged, by/liinges cid, a clamp-bar o rjaw, A, which is provided with a. narrow groove, a, for the reception of the edge/oi'l the sheet of metal to be bent up into form. On the other edge of the bed-piece B is hinged, by hinges gig, a bending-bar or former, lC, which is provided with a handle, I), for operating it. In addition to the/climp-bar A, for bending the sides of the vessel, there is a shorter, distinct clamp-bar, F, hinged by a hinge 9r'hinges,f, to the same edge of the bed-piece, as shown, for bending the ends oi' the article; and there maybe more than two clamp-bars, of diierent lengths, to suit different sizes of pans or other articles, all to beu/sed in connection with the same former C; or the latter may be divided into different ones, to correspond with the different clamping-bars, but this `is notnecessarymhile the use of the separator clamp-bars for the different lengths of the sides of the articles to be formed is essential with this instrument, since, after two opposite sides of'an .article are bent up, the clamp-bar for the other sides must pass between those already formed. The depth of the groove a in the clamp-bar is suiiieient for the highest sides of articles to b'et'ormed. Then when a less depth is wanted, the proper gauge is determined by pins or screws c c, inserted into holes in the clamp-bar A, at dil'erent distances from. the edge thereof, substantially as represented, for the edge of the metal to bear against. These gauge-pins c c may be used in connection with corresponding holes b b in the bedpiece, to keep the `two parts `rmly and exactly' in place. Holes b b, in different positions, areused to correspend with the different positions of the gauge-holes in the clarnpbar A.
The sheet metal is inserted as indicated by the horizontal blue lines x in iig. 2, and then the forming-bar`C is turned up, as shown by red linesin'the same figure, thus bending the metal up as represented.
What I claim'as my invention, and desire to secure by Letters Patent, is v v I The combination `and arrangement of the bed-piece B and the clamp-bar A and forming-bar C, hinged to said-bed-piece on opposite sides thereof, substantially as and for thepurpose herein specified.
I also claim hinging separate clamp-bars A and F to the same bed-piece B, for forming sides ot di'erent lengths, as herein set forth. I l
I also claim the gauge-pins c c, applied'in combination with the grooved clamp-bar A for the purpose specified.
The above speciicaticn ofmy improved machine for forming bake-pans, andmther-sheet-metal vessels of rectangular shape, signed by me this fourteenth day of September, 1866. Y
v BENJ'N. D. STEVENS.
