UNITED STATES PATENT OFFICE.

CONRAD FREDERICK SCHRIMPE, F PERTH AMBOY, NEW JERSEY, ASSIGNOR '10 THE PERTH AMBOY CHEMICAL WORKS, OF NEW YORK, N. Y., A CORPORATION OF NEW FUEL AND run raocnss or resume rfia sans.

To all whom it may concern:

Be it known that I, CONRAD FREDERICK SCHRIMPE, a citizen of the United States of America, and resident of Perth Amboy,

county "of 'Middlesex, and State of New Jersey, have invented certain new and use ful Improvements in Fuel and the Processes of Burning the Same, of which the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates .to fuels and the process of burning the same, and the principalob'ect of the invention is to provide a fuel which shallbe comparatively light in weight and may be easily packed .into briquets or tablets; another object of the invention is to provide a fuel which will produce a high degree of heat for a short length of time and which may be produced at a comparatively-low cost and which may be used for example by physicians, campers, tourists, etc. in emergency cases.

I have discovered that I can prepare a fuel having the above mentioned properties by mixing hexamethylentetramin with certain other materials giving a luminous flame and roviding a source of oxygen. I cite para or stearic acid as examples of substances giving a luminous flame as they not only give the flame a luminous efiect if desired but also' may serve as a binder, and

potassium permanganate as an example of,

a substance serving as a source of oxygen.

In carrying out the invention I may use hexamethylentetramin and potassium permanganate for example with or without the addition of a substance giving a luminouseflect, such as parafiin', etc., in the proportions as illustrated by the following examples;

1. Hexamethylentetramin 100 pts. Potassium ermanganate -r 20 pts. 2. Hexamethy entetramin. 100 pts. Potassium permanganate 20 pts. Parafii 20pts.

Patented Dec. 4, 1917.

I Application filed April 28, 1916. Serial No. 94,252.

sometimes be noticed. But if the mixture of oxygen-bearing substance is roperly carried out, none of these diflicultibs occur.

It i of course understood that potassium permanganate may be entirely or partly substituted y other oxygen-bearing substances as, for instance, the oxids or peroxids of the heavy metals or the nitrates of the alkali metals, which react with the hexamethylentetramin in the desired way.

Finally I wish to state that parafiin may be conveniently substituted by similar solid combustible I substances, especially those burning with a luminous flame, as for instance by a solid hydrocarbon of the aliphatic or aromatic series, or by the materials usuall applied in the manufacture of candles, o WhlCh especially stearic acid comes into consideratlon whenever it can compete in price with parafiin.

I claim:

1. A fuel containing hexamethylentetramin and a source of oxygen.

2. A fuel containing hexamethylentetramin, a source of oxygen and a substance giving a luminous flame.

3. A fuel containing hexamethylentetramin and potassium permanganate.

4. A fuel containing hexamethylentetramin, potassium perman anate and a substance givin a luminous ame.

5. A fue containing hexamethylentetramin, potassium permanganate and parburning with a luminous flame.

8. A fuel contaimng hexamethylentetramin, a substance capable of slowly giving ofi oxygen to the hexamethylentetramin and a solid hydrocarbon.

9. In the process of burning a fuelcontaining hexamethylentetramin, slowly liberating oxygen to prevent the formation of disagreeable gasest 10. In the process of burning a fuelcontaining hexamethylentetramin and potassium permanganate, slowly liberating oxygen to prevent the formation of disagreeable gases.

11. In the process of burning a fuel containing hexamethylentetramin, slowly libertaining hexamethylentetramin, liberating oxygen in the presence of a substance giving a luminous flame.

13. In the process of burning a fuel containing hexamethylentetramin, liberating oxygen inthe presence of the hexamethylentetramin.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

CONRAD FREDERICK SCHRIMPE.
