Specification forming part of Letters Patent No. 674578.

dated August 13, 1867.

To all whom it may concern:

Be it known that I, LOUIS S. Rosnms, of the city, county, andStatc of New York, have invented a new and Improved Process for Strengthening Rope and all kinds of Cordage whether made of hemp, cotton, flax, Manila grass, material, and for preserving the same from mold and decay; and I do hereby'declare that the follpwing is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, special reference being had to the accompanywhich form a part of this specification. It is-a-well-known fact that and textile fabrics made of hemp,iiax, an

rope, cordage,

. similar materials, when exposed to the heat .ly; but even if the tar is and moisture of the atmosphere Do prevent this decay, and even strength-- en the fiber, is the object of this invention, the object is thereby accomplished.

The method consists in subjecting the rope, cordage, canvas, and other textile fabrics to a process which supplies materials in a perfect and uniformmanner to the fibers, which will protect them from the injurious eli'ectsv of moisture, and the alternations of temperature.

Other processes have been employed. for the same purposes, but with only partial success,'owing to the condition of the material used, and the manner of its application.

One process for preserving rope, for instance, is that of passing yarn through boiling tar, and unless the temperature of the liquid be suited with exactness, and uniformity preserved in the movement of the yarn through it, there is danger of injuring the fiber, and of distributing the material unequalapplied at a proper temperature, and is equally distributed, its chemical efiect is deleterious, for rope thus treated decays progressively in a cold, and rapidly in a warm, climate. Besides, from the solidification of the tar thus applied, the elasticity of the rope is impaired, and it is therefore more liable to break.

or other similar.

.pidly de and 'neeting-pi-pes O .G,

To. all the processes as yet used for the preservation of textile fabrics the objections, as above stated, obtain.

One form of apparatus for carrying out my improved process is represented in the accompanying plate.

A in the drawingrepresents a retort, made of any desired form or size, -in which coaltar, wood-.tar, resin, or other oleaginons substances or compounds] are placed, and subjected to the action of heat from a suitable furnace. 13 represents the man-hole in the upper'portion of the retort, used in cleansing the same, or iu changing its contents. 0 G, a pipe -;commuiiicating with retort A, at or near itsj'top,passiug to and communicating d with chambers or;receptacles D. E represents-the discharge-pipe employed for removingtheoonte ts remaining after the operation is over. i 7

Heat being applied to retort A, containing coal-tar or some other ,oleaginous substances, or compounds, vapors aregenerated therein, which pass out into-the chamber 1), con-' tainingthe rope or other fabrics to be treated, or into'only one of the same as maybe desired. v

The application of heat to retort A is continued until the r' thoroughly u re the oleaginous vapors that they pervious to nioisfilrqand so as to resist'theaction of the atmosphere. llhen the articles treated may be removed from chambers B through the doors M M, and the chambers may then be refilled.

.It has long been established that the oils obtained from tar orother oleaginous substances and compounds, will, when properly applied, preserve fibrous materials from decay; and from the above description it .islapparent that by my process I-am enabled to more effectually saturate the rope and other like fabrics. with the preservative material employed than has been or can be done by any process heretofore in use, for the-reason that I use the preservative material in a va- -tical manner.

'I do not intend to hunt myself toauy particularform of apparatus; but

What I do claim 'as new, and desire to se-.

cure by Letters Patent is-- v lhe pfocess hefein described for p'reservin g rope, cordage, and all textile fabrics from mold and decay, by charging and saturgting them with h oleain0u .va morsfiiiilloom pounds, substantia yas herem" ese'iibed. 1
