Description: |
| Abstract:
The object of my invention is to construct a machine for preparing terne plates complete for roofing purposes in one general operation or in one passage of the plates through the machine. It consists, first, in gaging-bars for determining and gaging the width of the lap of the edges of one plate over the other for making the seam; second, mechanism for simultaneously bending said edges so as to interlock each other; third, mechanism for effectively closing the interlocked edges, so as to form a permanent seam; fourth, means for automatically distributing rosin over said seam while the sheets are advancing and for the purpose of soldering it in the ordinary manner by hand; fifth, in the proper location of a furnace containing a plurality of soldering-irons for the purpose of soldering said seam while the sheets are momentarily at rest; sixth, painting-rolls which serve to coat one side only with paint while the sheets are being drawn through the same; seventh, means for attaching the advancing end of the joined sheets to the disks of a reel for the purpose of winding said joined sheets into a roll; eighth, means for preventing the painted side of the sheet from smearing its unpainted side while the same are being wound into a roll on the reel; ninth, constructing the bearings for the reel in such manner that the reel may be easily removed from the same when it contains the full roll of the terne plates; tenth, means for drawing backward the joined sheet, so as to gage the rear end of the same against the gaging-bar and, finally, combining said means and mechanism in a simple and compact manner, so that they can be conveniently operated and will not be liable to get out of order.
Claim:
The combination in a machine for preparing roofing tin, of the table for holding the sheets of tin, gages for determining the lap of the ends of the same, clamping plates for bending the lapped portions of the sheets of tin to form the interlocking joint, hammers for flattening sai joint, and mechanism for operating said gages, clamping plates ioo and hammers. |
