IIEPROVED MATERIAL FOR JOURNALS AND BEARINGS, FOR LUBRICATING.

The Schedule referred to in these Letters Patent and making part 0! the name To whom it may concern:

Be it known that I, A. B. JONES, of Wilmington, in the countyof Hanover, and State of North Carolina, have invented certain new and useful Improvements iir-Lubricating Compounds; and I hereby declare the following to be a. full, clear, and exact description of the same.

The nature of my invention consists in the employment as a lubricating agent of disintegrated vegetable fibre, preferably that of the bamboo or cane, disintegrated by the explosive force of steam, in accordance with the process described in Letters Patent granted to A. S. Lyman, under date of 3d August, 1858, in combination 'with oil, or equivalent, in lieu of the means ordinarily employed for the purpose.

Cotton-waste, which is now so generally used in stuffing and journal-boxes, is objectionable onmany accounts, as it burns out rapidly, consumes much oil, and is in itself expensive. I have found, by careful and continued experiments, that the disintegrated fibre aforesaid, which first having been divested of its silicious coating, by the steam-blowing process, is then dusted and freed from extraneous matter, by means of a fan, or by other suitable means, is a much better material on all accounts. lVben used, for instance, in

the journal-box of a car-truck it will remain unimpaired fora length of time in which the cotton-waste, if it were employed, would need to be renewed two or three, or more times.

It also requires a less frequent application of oil, retaining and distributing the oil, or other lubricant, much better than the ordinary material, and being free fromthe silex contaiuedby vegetable matter in its ordinary condition, and which would impair its absorbent and lubricating qualities, and being moreover soft, pliable, and perfectly disintegrated, it is perfectly adapted to the uses for which I design it, and can be employed to advantage in stuffing-boxes of steam-engines, in journal-boxes, and, in fact in all instances, where a lubricator is required.

The first cost of the fibre is much less than that of any material heretofore employed, and in this respect alone, its employment is productive of advantages. I may add also, that the fibre, while fitted for use in the condition in which it comes from the steam-gun, may, if desired, be subjected to further treatment, such as washing, pressing, 850., sons to more thoroughly rid it of all extraneous matter, but in practice this will hardly be found necessary.

Having now described my invention, and the manner in which the same is or may be carried into effect,

What I claim, and desire to secure by Letters Pat.- ent, is

The employment, for-lubricating purposes, of vegetable fibre, disintegrated by the explosive force of steam, in combination with oil, or other suitable lubricant, substantially herein specified.

In testimony whereof, I have signed my name to this specification, before two subscribing witnesses.

A. B. JONES.
