UNITED STATES PATENT OFFICEO FREDERICK REYNOLD, OF NEWARK, NEW JERS'EY.
Specification forming part of Letters Patent No. 56,611, dated July 24, 1866.
To all wlwm 'it may concer'n:
Be ;it known that I, FREDERIOK REYNOLD, of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in the Mode of Manufacturing Harness-Nails; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and usethe same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a view of a nail before the softmetal head is applied. Fig. 2 is a view of a strip of the metal with which the heads of the nails are to be plated. Fig. 3 is a perspective View of a row of nails to which the soft metal and plating metal have been applied. Fig. 4 is a sectionalview taken through the line xx, Fig. 3. Fig. 5 is a perspective view of a nail after its head has been formed in a die.l Fig. 6 is a sectional view taken through the line y 3/, Fig. 5. Figs. 7, S, and 9 are perspective views of different styles of completed nails.
Similar letters of reference indicate like parts.
My invention has for its object to furnish an improved mode for forming soft-metal plated heads upon harness-nails; and it consists of the mode or process hereinafter described.
The nails A, one of which is shown in Eig. 1, are the ordinary annealed harness-nails,
which alone have sufficient pliability for harness-makers7 use. The head of the nail A is first dipped in acid to take off the scale and leave the nail perfectly clean. It is then dipped in melted lead or pewter, a globule of which adheresto thenail-head. The nails are then set in a row, points upward, upon a strip of very thin sheet metal or strip of foil of the metal with which it is desired to have the nailheads plated. This strip B offoil or thin sheet metal should be laid longitudinally in a halfround groove formed in the upper surface of the table upon which the work is done. When .the soft metal has become cold the row of nails is removed from the groove in which they were placed and separated or cut apart, and
the desired form 'given to the heads of the nails by a die. The die should be so formed as to leave the under side of the heads perfectly
