IMPROVEMENT IN THE MA NUFAICTU RE- or PAPER-PULP.
' 'Specification forming part of Letters Patent No. 12,361, dated February 6, 1855 To all whom it may concern: Be it known that I, HENRY GLYNN, of Baltimore, in the State of MarylanrL-ln tve discovcred improvements in the manufacture of pa-v pcr by which forgery by tranfers or attempts at alteration after obliteration of written or.
tacks of vermin and the effects of damp are My improvements are-confined to the prepamad'e. I impregnate the paper with fatty substances or'wax to such a degree that the snr-.
receive transfer-impressions shall be equallyand uniformly acted on-that is to say, by the ,the blank parts 'of the document as by the written or printed parts- -so that attemptsfto pressions on my paper-are frustrated. 1 e Into two hundred and fifty pounds of .pulp
potash or soda, previously dissolved in boiling water, and when this soap is thoroughly metallic saltin such quantities as. to render the introduced soap insoluble. Six pounds ot sulphate of copper I have found suflicient; but the quantity may be varied according to the-v qualities ot'--the so'apand the purposes for which the paper is designed.
results by a-sulphatc ofmagnesia', of which tired and fifty pounds of pulp. "Inaddition to ordinarysoaps L also use onein which bees or vegetable wax is introduced in place of fatty substances. When-I use wax 1 dissolve itbefore introducing it-into the pulp in a boiling 'ing' the alkali till the wax is thoroughly dissolved. Papertre'ated with this soap resists the effects of damp and. the attacks of vermin. It is'well known that rats and other vermin iii the tropics never attack wax candles or other objects of wax under the-severest gnawings of hunger. Being indigestible, it would kill them, and hence instinct impels them to reject it.
Among the advantages I obtain from the introduction ofinsoluble soaps-into the pulp are:
First, a greater quantity of fatty substances is embodied in the paper than is otherwise practicable. v v Sec0nd, I get rid of the labor and machinery hitherto necessary to saturate the soluble solutions are employed.
Third, while sizing with'alnm is incompatible, il'not impossible, withsnch solutions, [am
enabled to size with it in the ordinary manner and with the ordinarytacility.
Fourth, by insoluble soaps I attain security against fraudulent transfers that is unattainable with solu blesoaps.
Fifth, expensive phosphates have bcen proposcdtorender metallic saltsinsolublc in pulp;
bntby my process they are unnecessary, and 1 am enabled to manufacturepapers posscssing' the. advantages herein recited at a cost lit= tie exceeding that of ordinary papers.
Sixtlnby the use of insoluble soaps of wax or fa-t'a smoothersurt'ace is given to the'pa-per, I
and I avoid the usual operation of washing the pulp and the accompanyin ents. t v a Seventh, paper-hangings made by my pro cess are not subject -to mold 'or mildew, and
books made of it resist the ravages of vermin.
I claim-- Introducing into the imlpy mass soluble soaps of wax or fats, made as set forth, converting the same into insoluble soaps within the pulp by means of soluble salts, substantially as described, for the purposes of preventing forgcry, mildew, and the action of ill-:
sects, rats, and vermin.
