Description

@einen tetes atrnt @fitta L. M.. CRANE, CF BALLSTCN, NEIV Y-CVRK,

Letters Patent No. 61,321, dated January 22, 1867.

IMPROVEMENT IN SAFETY-PAPER.

TO ALL WHOM IT MAY CNCERN:

Be it known that I, L. M. CRANE, of Ballston, in the county of Saratoga, and State of New York, have invented a new and improved Safety Record Paper; and I do hereby declare that the following is a full, clear, and exact description thereof, vwhich will enable those skilled in the art to'lnake and use the same, reference being had to the accompanying drawings, forming part of'this specification, in which i i Figure 1 is a side vieuT of a cylinder papcr-makiug machine, showing the way in which my improved paper is manufactured.

Figure 2, a view of a piece of iny improved paper.

Figure 3, an enlarged or magnified vtransverse section of the saine.

Similar letters of reference indicate corresponding parts.

This invention relates toul new and improved lsafety record paper for wills, deeds, currency bonds, and other instruments or documents which are liable to be forged or fraudulently altered. i

The invention consists in inserting'in the paper pulp and incorporating with it, during the'process of manufacturing the paper, one or more threads or strips of gutta pei-cha or other material which will soften under the heat ofthe drying-cylinder of the paper-makingl machine and become inseparably united with the paper so as to be incapable of being removed or detached without destroyinrcr the latter.

In. order that my invention may be fully understood I will proceed toidescribe the Inannei` of manufacture.

A represents a vpulp vat, and B B two cylinders, havingktheir peripheries formed of wire cloth. C is an endless apron, constructed of felt, Working over suitable rollers, D, and in Contact with thepp'eripheries` of the cylinders B B. E represents two `pressure-rollers, and F a series of heated cylinders, p The above parts comprise an ordinary cylinder paper-making machine. 'I'he peripheries of the cylinders B B, as they rotate, take up a quantity of pulp, which is taken oli' by the endless felt apron C and conveyed tn the pressure-rollers E, which express the superfluous moisture from the pulp, the latter being taken from the felt apron beyond the rollers E and passed around the heated cylinders F, which dry it. G represents a spool, on which a gutta-percha thread, II, is wound. This thread H passes between the two layers of felt Vtaken by the felt apron C o from the peripheries ofl the twoI cylinders B B, (see iig. 1,) and the thread, in passing over or around the heated cylinders'F, becomes heated or warmed so as to soften and unite with the fibre of the pulp `andbe inseparably connected or incorporated with it, (see iig. I do not conne myself t'o a single thread, for more may be used if .necessary or desired, nor do I confine myself` toa straight thread or threads, for they may be inserted in serpentine form and arranged or disposed so that the denomination of a bank note or the name of an instrument or document may be Aindicated by the form, shape, number, or disposition of the thread or threads. The guttapercha thread or threads may also be made' of diierent colors, if desired, or may be covered with colored pulp,

A:as may be most eli'ective to prevent counterfeiting by photography.

I am aware that paper has been manufactured with threads inserted in its libre, but the threads have not been made of a material which will soften and unite with the fibre under the heat and pressure of the cylinders used in drying the paper or pulp.

I claim, therefore, as new, and desire to secure by Letters Patent- The inserting or incorporating of one or more threads or stripsef gutta percha, or a material possessing like properties, into the pulpor fibre of paper, during the ymanufacture of the same, and in such a manner that said threads or strips will be softened and firmly united to the fibre, under the heat of the drying-cylinders, substantially as set forth. o i

I also claim, as an improved article of manufacture, a safety record paper, made substantially as herein shown and described.

The above specification of my invention signed by me this 18th day of October, 1865.

L. M. CRANE.

WM. F. MCNAMARA, ALEX. F. RoBEnTs.
