UNITED STAT IMPROVEMENT IN MACHINES FR WATE'R-PROOFING,ARTIFICIAL FUEL.

Spccitication forming part of Letters Patent No. hdmlilg dated 'February 17, 1874; application filed September 20, 1873.

.To all uho-m Jit muy concern:

ABe itknown that I, EMILE F. Loiseau, of Manch Chunk, in the county of 'Carbon and State of Pennsylvania, have invented a new Aand useful Improvement in ll'Iachine-for \Vater-Proofing Artificial Fuel, ot' which thc following is a specification:

In the manufacture of artificial fuel from coaldust, or from a combination of coal-dust and other substances, it is extremely desirable to render the lumps or blocks waterproof, so that the fuel will not be injured by exposure to the weather; and not only that, but it is also desirable to give the lumps a coatingavhiclrwll render them less liable to, disintegrate or be broken; and my object in this invention is to provide a suitable apparatus for water-proofing or coating the lumps'of artificial fuel; and

v it consists in a machine havin g an endless belt or apron and tank,with the apron constructed and made to dip into t-he tank and immerse the fuel thereon, substantially in the manner hereinafter described.

In the accompanying drawing, Figure l represents a top or 'plan view of the machine. Fig. 2 is a vertical longitudinal section ot' Fioj. '1, taken on the line. a; T.v Fig. 3 is a cross-section of the tank, taken on the line y y.

Similar letters ot' reference indicate correspondin g part A is the bed-platt?. l represents stands on each end of the bed-plate, which support the drums of the endless belt or apron. Gare the drums, andD is theapron. ll represents the tank, which is supported -b v stands F F between the apron-drums. (l is a drip -pan, which receives any excess -ot' the waterproofing liquid, and conducts it tothe central opening II, which discharges it into a proper reser- Each edge of the apron l) is strengthened by a rope, and is provided with a series of balls, I. J represents recesses in the surface ot' the drums U, which, as the apron revolves, the balls enter, and serve as cogs to propel and keep the belt from slipping on the drums. The motive power is applied by means of a crank, K, or pulley on the end ol'l one of the drum-shafts. The tank E is supplied with the coatingliquid from an elevated reservoir, or the liquid is pumped up from below. The apron is made to dip into the liquid and submcrge the lumps of artificial fuel which it carries by means of the grooves L L of the inner sides ot' the tank, in which groove-s t-he balls I travel as the belt revolves. M are buckets, which extend across the apron to prevent the rolling or movement of the lumps ot' fuel when passing in or out of the tank. The lumps of artcial fuel are delivered onto the apron and carried through the liquid, and thereby receive a thorough coating. This coating immediately dries and becomes hard upon exposure to the air, and forms a perfect water-proof covering. rlille apron takes the coated fuel from the tank, and delivers it into a cart or other receptacle ready for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A machine for coating or water-proong artificial fuel, having a revolving apron, which is made to dip into a tank by means of balls and grooves, substantially as and for the purposes described.

2. In combination with a machine for coat ing artificial fuel, the drip-pan Gr, constructed and arranged as shown and described'.

3. In combination with the apron D, the balls I and buckets IVI, as and for the purposes herein shown and described.
