binds-(I fitattz Letters Patent No. 100,109, dated February 22, 1870.
IMPROVEMENT IN THE MANUPAC'I'URE OE PAPER.
The Schedule referred to in these Letters Patent and making part of the same;
To all whom, it may concern:
Be it known that I, E. B. BINGHAM, of Newark, in the county of Essex, and State of New Jersey, have invented a new and useful Improvement in the Mannfacture of Paper, of which the following is afull, clear, and exact description.
1n the manufacture of paper,'more especially the better qualities, it is all-important that the stud or pulp, when introduced to the paper-machine, should be as free as possible from specks of dirt and knots or strings, or coarse or irregular particles and extraneous substances, which, if worked up into the paper, deteriorate its quality. When it is considered how many and widely-different sources are resorted to for supply of the stock or material of which the pulp is formed, it will be readily understood that it is no easy matter to exclude from the stock all but pure and fine fiber, such as necessary to produce clear and good paper.
Pieces of paper, specks of rubber, and other extraneous matter, not unfrequently are mixed up with the stock used to form the pulp, and these, under the present customary mode of manufacturing paper, it is almost impossible to keep out of the pulp in an indigested form, or, if worked up, from afiecting the purity of the fiber. To obviate this, the stulfis frequently passed from the pulp or rag-engine; to a finishing, brushing, and grinding-engine or engines of like character, but diiferent grades, before introducing it to the screening-vat of-the paper-machine; but this does not accomplish the desired result, at least as perfectly so as could he wished, for much of the extraneous matter that has passed whole from the pulpengine, including substances which are incapable of forming fiber, is either similarly delivered from the finishing, brushing, and grinding-engine or engines, and
afterward passed through the screening-vat of the paper-machine, or is ground and worked up by the-grinding-engine, to the deterioration of the pulp. To remedy this, I take the stuff in the condition in which it comes from the pulp-engine, or before introducing 'it through the last of such engines, where more tl it to the finishing, brushing, 0r grinding-engine or engines, and pass it through the screening-vat, or through any suitable screening apparatus or device that will hold the extraneous matter and pass the fiber, thereby,
the foreign matter may be extricated by screening it before the stuff has been worked up in the finishing, brushing,vor grinding-engine, or at least last of such engines, where more than one is employeil, which foreigu matter could not beworked out afterward bysimply passing the finished, brushed, or ground pulp through the screening-vat of the paper-machine. Thus by merely screening the stuff in its passage from the ordinary rag or pulp-engine to the finishing, brushing,
or grinding-engine, or before passing it through the last of such engines, where more than one is employed, is the necessary purity or clearness given to the pulp in'the paper-machine.
As I employ no new or special devices in thus carrying out my improvement, means in present use serving, no drawing is necessary to explain my invention.
What is here, claimed, and desired to be secured by Letters Patent, is-
Passing the pulp,or stud through the screeningvat, or any suitable screening device, after it leaves the pulp or rag-engine, and before introducing it to the finishing, brushing, or grinding-engine, or before passlng oueis employed, as herein specified.
E. B. BINGHAM.
