IMPROVEMENT IN SPRlNG-PUNCHES FOR POTTERY-WARE.
Specification forming part of Letters Patent No. 157, 129, dated November 24, 1874 application filed January 13, 1874.
To all whom it may concern:
Be it known that I, A. H. HEWS, of North Cambridge, Massachusetts, have invented a Spring-Punch, as applied to Pottery-Ware, of which the following is a specification:
The object of my invention is to form the hole in a flower-pot, or any other pottery-ware requiring it, where the bottom may or may not vary in thickness. The machine of which this core is a part was patented by William Linton, February 12, 1861, N 0. 31,394, where it is fully illustrated.
The core E, attached to a perpendicular revolving shaft, is used to form the inside of flower-pots, the punch A being forced against the spring D by the bottom of mold, (not shown in diagram,) which is brought by use of lever to connect with core E. The rubber packing F, held between the cylinders B and 0, prevents the clay from entering the spring D.
I claim- The combination of core E with plunger A, spiral spring D, punch A, rubberpacking F, cylinders B and G, substantially as and for the purpose specified.
A. H. HEWS.
Witnesses:
THOMAS C. OoNNoLLY, J. W. OALLAMER.
