IMPROVEMENTS IN THE MANUFACTURE OF PULP FOR PAPER
Year: 1876

page_text: LETTERS PATENT to Henry Dyer, of Camberwell, in the County of Surrey, for
the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF PULP FOR PAPER."
PROVISIONAL SPECIFICATION left by the said Henry Dyer at the Office of
the Commissioners of Patents on the 14th February 1876.
HENRY DYER, of Camberwell, in the County of Surrey.
MANUFACTURE OF PULP FOR PAPER."
"IMPROVEMENTS IN THE
My Invention relates to improvements in the manufacture of pulp for paper
making, and it consists in the application and employment as materials for this pur-
pose of spent hops or spent malt from breweries or distilleries, either together or
separately, in combination or not with other materials, such as cotton, linen, hemp,
woolen or silk rags, and esparto, diss, palm leaves, straw, wood pulp, jute, gunney,
manilla, Indian grass, and waste paper.
The spent hops and malt, whether employed together or separately, and with or
without the other substances referred to, are treated by the processes and machinery
now in use for boiling, pulping, and bleaching, and when converted into pulp may
be at once made into paper or compressed and dried for sale to paper makers.
Instead of spent hops I may use fresh hops in the case of an over-abundant
supply or a crop unfit for brewing purposes on account of blight or other cause.
By my Invention I am enabled to utilize materials hitherto valueless for any
purpose except as a manure.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Henry Dyer in the Great Seal Patent Office on the 12th August
1876.

page_text: purpose of spent hops or spent malt from breweries or distilleries, either together
or separately, in combination or not with other materials, such as cotton, linen,
hemp, woolen or silk rags, or esparto, diss, palm leaves, straw, wood pulp, jute,
gunney, manilla, Indian grass, and waste paper."
The spent hops and malt, whether employed together or separately, and with or
without the other substances referred to, are treated by the processes and machinery
now employed for boiling, pulping, and bleaching the ordinary materials used for
paper making, and when converted into pulp may be at once made into paper or
compressed and dried for sale to paper makers.
Instead of spent hops I may use fresh hops in the case of an over-abundant
supply or a crop unfit for brewing purposes on account of blight or other causes.
The proportions of the different substances would be readily understood by paper
makers, and may be varied to suit their various requirements.
By my Invention I am enabled to utilize materials hitherto valueless for any
purpose except as a manure.
Having described, the nature of my said Invention and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein-before in part recited Letters Patent is, the application and employment for
the manufacture of pulp for paper making of spent or fresh hops or spent malt,
either alone or together, and in combination or not with other materials ordinarily
used for paper making, as specified.
In witness whereof, I, the said Henry Dyer, have hereunto set my hand and
seal, this Twelfth day of August, in the year of our Lord One thousand
eight hundred and seventy-six.
