UNITED STATES PATENT OFFICE.
F. on CAMPOLORO. on N YORK, N. Y.
IMPROVEMENT IN THE MANUFACTURE OF PAPER-PULP.
Specification forming part of Letters Patent No. 29.471, dated August 7, 1860.
per, 851e,; and I do hereby declare that the following is a full, clear, and exact description of I the same.--
' Myinvention consists in the employment for the purpose of producing pulp for the manu facture of paper, &c., of the cobs of Indian corn or maize, either alone or with the husks.
'To enable those skilled in the art to make and use my invention, I will proceed to describe it.
The large quantity of corn in this and other countries and the qualities of the leaves and talks of the same haveiuduced manufacturers nd inventors to make manifold experiments or thepurpose of finding out the propermeans to use said parts oi the corn for paper-pulp, and they have succeeded as far as the inferior sorts of paper are concerned; but it has not been proposed in any case to use the cobs of corn; neither have former experiments with Other parts of this plant been successful in producing white paper. The cobs in themselves are generally so white that the same,
when boiled and mashed up in a proper vessel, form a pulp of s'uflicient whiteness to form white paper without previously bleaching the pulp; but if the cobs,togetherwith the-husks, are used,the pulp produced from the same has first to be bleached before it can be used for the manufacture of white paper.
The bleaching, where'it is necessary, I accom plish in the ordinary manner by the means of chlorine, or by the employment of hypochloride of potashor of soda, either with or withontthe application of heat, and the pulp thus'produced can be employed for the pur pose ofmanufacturingperfectly white paper,
in the ordinary manner.
By these means 1 am enabled to produce a cheap paper of good qualities, and the material for the pulp will not likely become scarce, since I make use of those parts of the corn which are generally considered of very little or no value for any otherpurpose.
- ,-I am aware that the stalks and leaves of corn have been used before for the purpose of producing-pulp for paper. Those I do not claim; neither do I claim. the employment for this purpose of the husks or covering-leaves of the cars, such having been proposed by Mr. D. Harcourt in his English patent of 1838; but
What I do claim as new, and desire to secure by Letters Patent, is-
The employment of the cobs of Indian corn, either alone orwiththehusks, substantially as herein described, for the purpose of producing pulp for paper.
F.- on ooMPoLoRo."
