Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
“For Machinery for Manufacturing Tin Ware; Edward M. Converse, Southington, Hartford County, Connecticut, July 20.
Those acquainted with the progress made within the last thirty years in the manufacturing of tin ware know, that with the exception of soldering the work together, nearly the whole of the labour is performed by machinery.
The present patentee has described and figured machinery for turning straight edges, for grooving, for double seaming, for setting down bottoms on vessels, for turning edges for wiring, and for burring.
In their general construction these machines resemble those heretofore known, but with certain alterations which the patentee believes to be improvements; and the whole description of which occupies more than twenty-four pages. He says that they are cheaper, more durable, and perform the work better than any others. The framework of his machinery, the wheels, boxes, and most other parts, are made of a compound of zinc, copper, and tin, in the proportion of ten parts of the first, one of the second, and half a part of the third. He mixes these by melting together the copper and tin, to which he adds as much zinc as the weight of both. This mixture is then combined with the remainder of the zinc, in a fused state.
This metal, we are told, is valuable for making a great variety of articles in domestic economy; that it is recommended by its cheapness, and freedom from corrosion, and that it receives a fine polish.
The patentee, although he inserts the recipe, does not, we suppose, intend to claim this particular composition as making a part of his patent, as it is a kind of mixture well known in the manufactories' of Europe, and in many of our own. He has not, in fact, inserted any claim to it.”
