Description

, UNITED STATES PATENT OFFICE.
THOMAS GODFREY AKINS WILSON, CF VANCOUVER, BRITISH COLUMBIA, CANADA.
PROCESS OF MANUFACTURING BRIQUETS.
No Drawing.-
To all whom it may concern:
Be it known that I, THOMAS G. A. WIL- SON, a citizen of the United States, residing at Vancouver, in the Province of British Columbia and Dominion of Canada, have invented a new and useful Process of Manufa cturing Briquets, of which the following is a specification.
This invention aims to disclose a novel and improved method of manufacturing briquets from coal and a'sphaltum.
Such briquets as are now manufactured frequently crumble to pieces when used as fuel owing to the imperfect methods p'ursued in their manufacture, the mass constituting the briquets not being homogeneous and the particles not being properly bound together;
It is therefore the aim ofthe present invention, primarily, to disclose such a method of manufacture as will render the mass of the bricks homogeneous throughout and will result in the particles of asphaltum and of coal cohering to afford a compact mass.
In carrying out the invention, the waste from the mine or in other words, the slack 00:11, as free from mining dirt and soil as it prefis possible to obtain it, and containing moiserably not more than five per cent. 0
ture, is crushed and screened to about the size of wheat grains. After being thus treated the coal 1s conveyed to a mlxer and after being placed therein is heated to from 130 F. to 180 F.according to the condition of the coal, it beingin the mean time during the heating process, thoroughly agitated and mixed. At the same time, asphaltum (pref-' (-rably that quality known in the trade as grade D soft) is heated to the boiling point or.in other words, until all of the oils are driven off and the binder is tough when cold. The binder, while hot, is thensprayed into the coal in the mixer, and the mixing operation is further'carried on. When the coal and the binder, in the nature of the asphalt-um mentioned above, have become thoroughly mixed, the mixture is cooled to Specification of Letters Patent.
Application filed July 26, 1909. SerialNo. 509,618.
Patented-May 24:, 1910.
about 80 F. or even a lower degree if found expedient. The mixture is then conveyed to the briquet press where it is pressed into briquets of suitable size and form.
It is preferable that from 4 to .7-1;% 'of binder be used in connection'with the coal employed, although thisper cent. is governed by the volatile matter in the coal, inasmuch as a lessper cent. of binder will be required where there is a high per cent. of volatile matter in the coal and vice versa, a greater per cent. of binder will be required where there is a less' per cent. of volatile matter.
It will be observed that the coal andthe binder are heated to substantially the same degree and that the binder is sprayed into the coal in the mixer, this mixer being entirely closed, preferably, so as to retain the combustible ases in the mass and the fact will be readi y appreciated that this method of procedure is productive of much better results than where the coal and the binder are merely mixed half with half and heated as a mixture, the spraying of the molten binder into the mass of coal resulting in a much more intimate mixture of the two substances than where/ they are mixed together prior to the heating process.
That is claimed is:
The hereindescribed method of manufacturing briquets consisting in heating a mass of finely divided coal in a closed mixer to a temperature of from 130 degrees F. to 180 degrees F., heating a massof asphaltum to the boiling point and until all oils are driven off, and finally spraying the molten asphaltum into the mass or: coal while under agitation in the mixer.
In testimony that I claim the foregoing as my own, I have hereto aflixed my slgnature in the presence of two witnesses.
