Letters Patent No. 105,160, dated July 12, 1870.

IMPROVEMENT IN THE MANUFACTURE 01-". TOBACCO-PAPER.

l'hoschednle referred to m then Letters Patent and making part of the same.

In the'patents issued to myself and P. M. Consuegra, dated 2d February, 1869, we have set forth'a manufacture in which tobacco alone is employed as the material, and the treatment may be so conducted as to retain in the paper all the strength of the i50 bacco.

I have now discovered that the paper may be-made materially stronger and more perfect, without the loss of its good qualities, by the addition of a material which is neutral in its effect on the taste or smell when the paper is used in cigarettes or otherwise.

- I use the fibrous material obtained from the muse teams of the Philippine islands and adjacent regions, and commonly known in commerce as manilla.

' -I prepare the tobacco, as described in our previous patents, without any necessity for washing or rejecting any waters.

I prepare the manilla by a separate treatment down to a certain point, and afterward treat the two materials together, and work them out in a mingled pulp. I use from ten to thirty per cent. of manilla, and the remainder of tobacco-stems or leaves. The manilla requires .thelongest' treatment. ,I boil it in an alkaline liquor, formed first as a weak solution of lime, commonly known as milk of lime, and afterward saturated with soda-ash. i

The boiling should be continued about twenty hours, varying somewhat with the condition or character of the materials. It is then washed in cold water, changing the water as much as may be necessary until all but the very slightest trace of alkali is removed.

The common rag-engine of a paper-mill may be used with good effect for this preliminary washing.

Having by this means partially reduced the tough fiber of the manilla, and extracted by the ordinary means the grit and other foreign matter, I am' ready to mingle it with the tobacco,'previously boiled some six hours in a small quantity of water, andproceed to beat, grind, and brush the mingled material to produce a fine and uniform pulp.

This pulp is afterward treated- :in the ordinary manner, using the Fourdrinier or any other form of machine. 7 V I can, if preferable,iu "anyinstance, to save time, introduce the manilla material in the form of previously-njanufactured manilla-paper. It is only important that insuch case the manilla-paper shall not have been sized with any material which will give taste or smellto the product,

The tobacco-paper thus produced, is, fine and strong. It will bear wetting. and handling, and will conform to all the requirements of a good paper for all smoking purposes. v

A high degree of toughness is-imparted by the jmanilla, without sensibly depreciating its smoking qualities.

In running out this improved paper, the sheets of previously-manufactured paper, described in our previous patent as run between the sheet of pulp and the felt, may be introduced as a safeguard against possible accidents, if desired. But I have not in my experiments found it necessary, and believe that it may be safely dispensed with altogether.

I claim The toughened tobacco-paper herein described, formed of pure tobacco with the strength retained, with the addition of a neutral toughening material, prepared and combined in the manner and for the purposes herein set forth.

In testimony whereof I have hereunto set my name in presence of two subscribing witnesses.
