APPARATUS FOR CHARRING TIM BER.

SPECIFICATION forming part of Letters Patent No. 282,895, dated July 31, 1883.

Application filed April 28, 1883.

To all whom it may concern:

Be it known that 1, JAMES D. STANLEY, of

. Wilmington, in the county of New Hanover and State of North Carolina, have invented certain new and useful Improvements in Charring Timber, of which the following is a specification."

My invention relates to a means of charring. timber for piling, bridge construction, and other purposes. I V

. Itis well known that by charring its outer surface timber may be preserved from decay and. protected from the ravages of the teredo and other destructive insects 5 and my invention has for its object the rapid, effective, and

uniform treatment of the timber, as hereinaf-w doors are shown by e. and the ash-pits by f. y

B B are iron, columns or frameswhich sustaintransverse iron rollers g. The rollers are elevated above the lowest portion of rimeter of the cylinder A.

C 0 indicate a railroad-track running in the direction of the length of the charring-cylinthe pcder A.

In conducting the operation of charring timber the charringcylinderAis first adequately heated by fire in the furnaces, and the timber of any length is placed upon a car, so as to be brought as near the height of the rollers g as is practicable. The timber is then projected forward centrally within the cylinder A, in which it is surrounded on all sides by the highly-heated surfaces of the cylinder, and subjectedto the necessary temperature. The heat is equally distributed over the entire surface of so much of the timber as is then in the cy1- inder, and no portion of said surface is unduly (No model.)

scorched. The portion of thetimber first in troduced into the cylinder is allowed to remain therein for a sufficient length of time for ing it must be determined by circumstances such as the character, dryness, &c., of the wood, or other considerations. The forward end of the timber as it is carried through or beyond the cylinder is received upon the for ward roller, and the timber conveyed to a second car placed on the track 0 O, and thereafter taken to its destination. If necessary, a series of rollers may be used at each end of the cylinder.

A brush, D, is arranged at the outlet of the cylinder for extinguishing the fire, if, 011 the timber leaving the cylinder, it is found to be ignited. The brush consists of a platecentrally perforated, and having a concentric row of holes provided with bristles or fibers of asv V bestus.

My invention effects the purposes for which it is designed in a rapid and uniform manner. Having described my invention, I claim- 1. In an apparatus for charring timber, the

combination, with a horizontal cylinder adapted to be directly heated, and provided at one end with a non-combustible brush, of stationary rollers and means for delivering the timber thereto, substantially as set forth.

2. In an apparatus for charring timber, a horizontal cylinder, furnace for heating the same, stationary rollers for supporting the timber, and trucks for delivering and removing the timber, all combined, substantially as described.

3. In an apparatus for, charring timber, the

combination, with the cylinder A and furnace B, of brush D, rollers G, supported by frames B, track 0, and trucks or cars thereon, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand this 24th day of April, A. D. 1883.
