COMPQSITION MAKING BRIQUETTES.

No Drawing.

To all whom it may concern Be it known that I, JACOB Sno'rwnLL RoBEsoN, a. citizen of the United States, and

resident of Pennington, in the county of; Mercer and State of New Jersey, have 1nrcnted certain new and useful Improve ments in Composition for Making Briquettes, of which the following is a specification.

This invention 1s an improvement in the manufacture of compositions of matter and includes a novel binder for use in holding together particles or masses of other material. The composltlon 1s primarily 1ntended as a binder for the making of bri quettes, and may be used in connection with coal dust or other fuel, iron ore, sand for molders cores, or other inert material, to which it is desired to give definite form, hardness and Water-resistant qualities. In the manufacture of fuel'briquettes it is important that the briquettes be substantially water-resistant so that little or no water be absorbed when subjected to rain or dampness during shipment or storage, and it is also important that the briquettes benot too brittle, as otherwise they break down during shipment and handling, whereby the main advantage of forming the coal dust into briquettes is lost. It is also important that the briquettes burn freely without the production of objectional volumes of smoke, and that the minimum of non-combustible products be employed.

In my prior Patents 841,718 and 851,381, I have disclosed a hinder or adhesive'compound in which sulfite cellulose liquor and wood tar are employed. Such a binder has certain advantages, but experience shows that the product is too brittle for some purposes. In my prior Patent 851,380 I have disclosed a binder or adhesive compound in which sulfite cellulose liquor and molasses are employed, but if, these two be employed as the sole ingredients of the hinder the briquette orother product, as shown by experi-- ence, would not be as water-resistant as is rlesirable for most purposes.

The main objeetiofmy present invention is to produce a compositaon or adhesive material and briquette or other body employing the same, and which will be free from the objectionable qualities above referred to, and

which will be inexpensive to manufacture,

and include only easily obtained, handled Application filed August 3,1921. Serial 1T0. 489,623.

and assembled ingredients, completely combustible and preferably of an organic nature. "In my improved adhesive composition I employ proper proportions of a sulfite solu-' tion of the non-cellulose elements of woody tissue, the liquid residueof, destructive distillation preferabl thick residuum of plant juices. Itwill be noted that all of these ingredients are of 'vegetable origin and include the non-cellulose ingredients in different forms. By the proper combination and proportions I avoid undue brittleness, and at the same time get water-resistant or repellant properties. In its preferred embodiment the combination includes sulfite cellulose liquor, approximately 48 per cent, crude molasses, approximately 38 per cent, and wood tar, approximately 14 per cent. This binding agent may be used with coal dust or finely divided coal in the proportion of about 6 per cent of the binder to 94 per cent of the coal. Other percentages of the binder may be necessary with other aggregates or material to be held in compact and definite form. When the of fuel briquettes, the latter are preferably of woody tissue and the pressed in suitable molds to the proper size I and shape, and are heated to approximately 400 Fahr. to drive off moisture and prob-1 ably efi'ect certain chemical reactions be tween the ingredients of the binder. The crude molasses may be that commercially sold in the market as blackstrap and with or without previous fermentation and alco hol extraction. The sulfite cellulose liquor may be the ordinary concentrated liquor of commerce which is of approximately 301 B. gravity. The wood tar maybe the ordinary article of commerce sold under that name and may be of varying degrees of plasticitybinder is of t e sulfite cellulose liquor, about one-third to two-fifths is of crude molasses, and approximately one-seventh is of wood tar.

It is quite important that the tar constituent be not materially less than one seventh although a slight reduction below this amount might give satisfactory results. The

nu Y

wood tar seems to have a very important 2. A binder for briquettes including moefiect in rendering the com osition waterproof, and for this purpose might use coal tar, liquid bitumens or asphalt, or mixtures of these, in place of the wood tar. All of these tarry or pitchy substances are fairly easily emulsified with sulfite cellulose liquor and the molasses.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A composition of matter for use as an adhesive or binding agent including suifite solutions of the non-cellulose elements of wood tissue, liquid residue of destructive distil ation of woody tissue and thick residuum of sugar bearing plant juices.-

lasses, sulfite cellulose liquor and wood tar.

3. A. composition of matter for use as an adhesive orzbinding agent including sulfite cellulose liquor, approximately one-half, crude molasses, approximately two-fifths, and pitchy matter, approximately oneseventh.

4. A composition of matter for use as an adhesive'or binding agent, including sulfite cellulose liquor, approximately 48 per cent, molasses, approximately 38 per cent, and tar, ap roximately 14 per cent.
