Description: |
"This invention relates to that class of shingle-cutting machines in which the cutting operation is performed by a reciprocating knife, a compression-roller being attached to the knife-carrying frame in a suitable manner, so that the roller moves with the reciprocating knife and preserves the solidity of the timber of the shingles being cut, and for which reissued Letters Patent were granted to me, dated June 15, 1880, and numbered RE9,251 and RE9,257..." |
