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.
“For a machine for Manufacturing Wrought Nails and Screws; Stephen I. Gold, Cornwall, Litchfield County, Connecticut, July 25.
The description of this machine is of considerable length, and not easily abridged, as it attempts to describe a machine consisting of many parts, in words alone, without reference to the drawing; nor is the latter sufficiently well executed to give a distinct view of the machine. Much pains has evidently been taken with the specification, the result of which evinces the necessity of referring, throughout, to descriptive drawings, for the purpose of clearly explaining complex machines.
There is no particular part of this machine claimed, the general arrangement being considered as new.
To a strong frame, is fixed an anvil, with its face downwards; in this fáce, grooves, or cavities, are formed, which are the counter parts of one-half of the nail, or screw, to be made. Under this a roller is made to pass, which has grooves to correspond with those on the face of the anvil. The thread of the screw is to be formed by this kind of operation, but, as the juncture of the moulds, or dies, would leave a ridge, the roller passes twice over it, the wire being turned one-quarter round between the two motions. The screws may be headed by methods heretofore used. The chisels which are to cut off the wires, or nail rods, are acted upon by levers, cranks, and hammers; the rods are kept in a fire, in numbers, without a blast, and two are to be passed in at one time.
When a model is received, we may be able to form a better judgment of the whole, than can be done from the materials now before us; should it appear to merit a particular description with drawings, they shall be furnished.”
