Description

Patented Jan. 5, 1937 UNITED STATES PATENT OFFICE THE SAME Alden J. Decker, Du Bois, Pa.
No Drawing. Application October 9, 1935, Serial N0. 44,304
2 Claims.
Percent 15 Pulverized bituminous coal 66% Waste paper made from wood pulp 20 Asphalt 12% The waste paper, such as newspaper, is first 20 ground in water until it is in a mushy form, after which the pulverized coal is added to this mushy ground paper and thoroughly mixed with the latter. Any surplus water is then squeezed out of the mixture, whereupon the asphalt is added. The resulting composition is then pressed into the form of briquets of uniform size, after which the briquets are either allowed to dry naturally or are artificially dried.
It will be noted that pulverized bituminous 30 coal is a greatly predominating ingredient. As
immense piles of fine or pulverized coal accumulate at all bituminous coal mines, and as such fine or pulverized coal has very little commercial value, it will be practically given away to any 35 one who will remove it. Thus, I make use of a predominating ingredient which is available in large quantities at little or no cost. Practically the same economical advantages maintain in connection with my use of waste paper. By
grinding the paper in water until it is in a mushy form, it can be thoroughly mixed with the coal and pressed in brick form, the asphalt being added to provide a partially combustible binder that serves to assist in holding the coal and paper together and to enable the production of briquets closely resembling lumped bituminous coal. However, the present fuel may be more readily handled and stored without the production of dust or soiling of the hands, and the fuel will burn freely and so completely as to leave very little residue or ashes. The asphalt is the same as the material of that name commonly used in resurfacing highways.
While I have found that the proportions of the ingredients stated give the best results, it will be understood that the same may be varied to some extent without departing from the spirit of the invention as claimed.
What I claim as new is:
1. A process of producing a solid fuel briquet, comprising grinding about 21 parts of wood pulp paper in an excess of water until it is in a mushy form, adding about 67 parts of pulverized coal to and thoroughly mixing the same with said ground paper, squeezing surplus water from the mixture of ground paper and pulverized coal, adding about 12 parts of asphalt to the mixture of ground paper and coal after the surplus water has been removed therefrom, and pressing the resultant mass into briquets.
2. A solid fuel briquet consisting of a compressed and dried mixture of pulverized bituminous coal, wood pulp paper which has been ground in water, and asphalt, in approximately the proportions of 66%% bituminous coal, 20
wood pulp paper, and 12%% asphalt.
