Specification of Letters Patent.

Patented Januild, 1913.

Application filed April 24, 1911. Serial No. 623,458.

To all whom it may concern:

Be it known that I, HARRY H. HARTUNG,

a citizen of the United States of America,.

and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Processes of Manufacturing Artificial Fuel, of which the following is a specification.

The present invention relates to the process of manufacturing artificial fuels, and has for its object the production of a fuel having a base composed of waste vegetable products, and particularly the waste material of canning factories, such as corn cobs, peach pits, and the like, these waste materials being ground and thoroughly mixed, and then bound together by a starch paste including melted paraflin, to which is added crude petroleum, the whole mass being subsequently subjected to pressure and molded into a hardened mass having elongated form. Such a fuel, when thoroughly dried, is very inflammable and is adapted for use upon andirons in a fireplace, or may be utilized as kindling in building a coal fire.

Of the drawings: Figure 1 represents in perspective a log or other elongated member embodying the features of the present invention, and Fig. 2 represents a transverse section of the same.

In the drawings, 10 represents a mass of fuel in an elongated form, preferably shaped like a log, with a rough, uneven exterior, provided with a plurality of protuberances 11 which will assist in more readily igniting the fuel.

The basic elements of this fuel are waste products, preferably vegetable products, such as corn cobs, peach pits, and the like, which are usually found in the refuse from canning factories, and at the present time have no commercial value. These various materials are 'collected together and ground,

after which they are thoroughly mixed. In,

the meantime, a binder is made by boiling starch until it is a thin paste. This binder of starch is then thoroughly mixed with the basic elements of the fuel, and crude petroleum is added, and thoroughly mixed with the other materials forming the fuel. This mixture is then placed in suitable molds and subjected to hydraulic or-other pressure to cause the mixture to be molded into a compact mass having an elongated form, preferably in the shape of a log or stick of wood,

the ground waste material.

the surface of which has a plurality of proectlons therefrom, as indicated in the drawings. The binder of starch is readily inflammable and is adapted to bind together Under certain conditions, however, it is found advisable to add to the starch paraffin in small quantities to make the binder more effective in its operation. When the artificial logs composed of this mixture of ingredients are intended for use near the place of manufacture, this binder will be amply sufficient to bind the ingredients together until use, but when it is intended that the logs should be shipped from the place of manufacture to a distant point, it is then essential that the binder should include some other ingredients which will make'the entire mass when dry less liable to crumble and become broken in transportation. Paris is added to the starch and parafiin, and mixed thoroughly therewith to form the binding material.

The various ingredients forming the fuel are mixed in about the following proportions, although it is obvious that the proportions may be varied somewhat without affecting the principles of the present invention. The waste vegetable products, 80%, binding material, 14%, crude petroleum, 6%. When the binding material has other ingredients than starch therein, such as plaster of Paris or paraffin, they are added in the proportions of 2% each, and the starch is reduced to the same extent.

A very effective fuel may thus be formed,

In such cases, plaster of which will give a great heat, and the expense of manufacturing the fuel, utilizing,

be used on the andirons in an open fireplace, it is believed will be fully apparent without further description.

Having thus described my invention, I claim:

1. The process of manufacturing artificial fuel which consists in grinding and mixing together inflammable materials, forming a paste of starch and Water, adding paraffin to said paste, heating said paste so that the paraffin will melt and'penetrate all portions of the paste, adding said paste and crude petroleum to the mixture at inflamma ole materials, ancl then molding the combined. minture under pressure.

2. The precess of manufacturing artificial 5 fuel which consists in grinding and mixing together inflammable materials While in a clry state, forming a paste 0t starch ml water, adding paraflln t0 saiel paste, heating said paste so that the paratfin Will melt and to penetrate all. pertions of the paste, adding all neaaeae said paste ancl crucle petroleum t0 the mixture 0f inflammable materials, and then molding the combined mixture uncler pressure.
