UNITED STATES PATENT OFFICE.
THOMAS WELHAM, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVED MACHINE FOR PRESSING AND SHAPING SCREWS.
Specification forming part of Letters Patent No. 47,236, dated April 11, 1865.
l/revolving-dies for pressing and shaping screws" instead of cutting the threads as heretofore.
Figure 1 represents a side elevation or front view, and Fig, 2 a cross section.
A represents the upright frame; 13, a band pulley; 0, a fly-wheel.
I) is the toothed driving-wheel.
E is the pinion that gears into and connects the driving-wheel D and top cog-wheel, G. The wheels operate on shafts set in ordinary boxes on the sides of the frame.
H represents a steel die,madenearl5 square and rounding on the face, in which the size and hape of the screw is sunk. The dies H II are adjustable and set firmly in stocks J J, that are cast solid with their toothed wheels G G, A ()n the shaft of the band pulley B and I tiy-wheel 0 there is a revolving cam, K, that operates the upright arm L of the horizontal hammer M. The front end of the hammer his an adjustable die, N, with a chisel-point, for the purpose of making the head of the head of the screw and the nick in the head at the same stroke. The rear end of the hammer M moves in a cylinder, P, containing a spiral spring, It.
8 represents the -wire (out of which the screw is formed) as ready to come in contact with the dies.
As the driving-wheel D revolves, it drives the pinion E, which operates the'toothed wheels G G and revolves the stocks J J, containing the screw-dies H H, and as the dies come in contact with the wire S they draw the wire through between therevolviug dies, at the same time the cam K passes from the arm L and releases the hammer M, that is i then drivenforwa rd by the power of the spiral spring It against the front end of the wire, making the head and nick of. the screw, the die pressi'n g, shaping, and cutting ofl'the screw from the wire, (by the pressure,) thescrew dropping below and leaving the wire ready to i come in contact with the next die.
Vhat I claim as my invention, and dcsiic ,THos; WELHAM.
