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. There are no patent drawings available. This patent is in the database for reference only.
“This is one of those simple and obvious improvements, which, when once presented to us, excites our surprise that it should not have been made long ago. The improvement is upon the form of the exterior of the cast-iron boxes in common use. These have, heretofore, been cast tapering on the outside, as well as within, but in the reversed direction, and they have been so made, because, in this form, the pattern, in casting, would readily deliver from the mould. When thus cast, the smaller, or front box, has its exterior diameter smallest at the end towards the centre of the hub, or nave; the consequence of which, is, that the least start, after it has been driven into its place, loosens it in every part, and it readily comes out. The larger box, on the contrary, has its larger diameter towards the centre of the nave, and cannot, therefore, be driven into its place, but must, necessarily, be secured by wedges, which are very apt to work out. The patent boxes are made perfectly cylindrical on their outsides, with the exception of a small distance from the end which is first to enter, where they are sufficiently tapered, or chamfered, to prevent their cutting the wood before them. The ears, or projections, which are to prevent the boxes from turning, are made sharp on their inner ends, and, when driven, force their own passageway.”
