DRAW-PLATE FOR DRAWING WIRE.
Specification of Letters Patent.
Patented Sept. 19, 1905 Application filed March 7, 1905. Serial No. 248.806.
To 11- whom it may concern:
Be it known that I, ANDREW RATHBONE, a subject of the King of England, residing at Grappenhall, Warrington, in the county of Lancaster, England, have invented new and useful Improvements in Draw Plates for Drawing Wire, of which the following is a specification.
- This invention has reference to draw-plates or wortles for drawing wire; and it has for its object and effect, primarily, to provide an improved draw-plate or wortle which shall not be so liable to become bowed and its life, correctness, and utility is generally increased; and it has primarily for its object to prolong the life of such plates or wortles and render them easier to work. In practice this bowing of wortles or draw-plates takes place to a very great extent, and when plates are pricked or drilled in the ordinary waythat is, the holes all pricked or drilled on one side-only one side of the tool is spread in battering, with the result that the area of the face becoming greater on one side than the other the plate or wortle becomes bow-shaped or bowed, which ultimately destroys the plate or makes it useless by either splitting itself or breaking off the ends of the punches, owing to the holes being out of shape.
Now, according to this invention, to obviate this bowing the plates or wortles are pricked or drilled with holes from both sides-that is to say, the small portion of the draw-holes at which the actual drawing takes place will be on the opposite sides orfaces of the plateas will also of course the larger portions or mouths of these holes.
A draw-plate according to this invention is illustrated in the annexed drawings, in which Figure 1 is a longitudinal section, and Fig. 2 a plan.
In the drawings, (6 represents the small p0r. tions of the draw-holes at which the actual drawing or reducing takes place, and it will be noted that the successive holes of a row longitudinally are on the opposite sides or ANDREW RATHBONE.
