My new process, and the product thereof which is the subject matter of this application, attains all these desirable ends'without the necessity of going through the va- 6o rious complications of the former processes,
as will be seen from the following. As av lowing is a. specification. basis for my new explosive I use preferably This in ventionxelates to improvements in potassium chlorate; and the carbohydrate 1n the aggregate I have found, as stated in 65 my chlorate of alkali-metals and carbo-hy- 1o 'drate explosives and it relates particularly my former application, to-best be about one To all whom it may con-cam: Be it known that I, Jams F. OBnmn, a citizen of the United States, residing at Chicago, in the county of Cook, State of 5- Illinois, have invented new anduseful Improvements in Explosives, of which the foli to the piovision of certain combinations and compounds for the purpose of simplifying .theprocess of. manufacture ofthe explosive. -Thefpresent invention follows along the general line of my explosives of the class described, and particularly follows alongthe lline'ofmy explosives asdscribed in myllppli'eatzions for Patent filed on Septhird by weight-ofthe amount of the chlo rate. But in this case, theearbo-hydrate is made up. oftwo distinct substances, one liqbid and the other solid; and typically-I -70 use a certain proportion of starch,'preferablybrowned starch, and a certain prop rtion of molasses, preferably beet suganmolasses on account of its heapness. i,'The" l "i temberSth, 1911, SN. aim-u; September v p a entities of starchand molasses-are 75 2o. th,.191 1,'S.

the second application-cited, -my explosive n composed that theprocesso't n necessitated cooking or heating I 25 some of the ingredients before they could he finallymixed to form the explosive; "My present; invention obviates this preliminary heating orcoo and-enahles-me to directly jfiorm'the explosive from'the suitable ingredient-s withpnt'any preliminary processesother' than grinding er'finely dividing someof theingredients. In my former processes of the first two cited applications for the making of my explosive I had first coolied or heated the ca 1- hO hydrate, adding water if necessary, so that' a -liquid was formed. This' lieated liquid was then mixed witli the chlorate and other ingnedients'and came out-as a. plastic or semi-fluid mass. mass was then dividedinto small particles of suitable .-siz e-and shape and then dried. In order that each particle of-the. resultant'explosive have its due proportions of the difierent ingredients, it is, necessarythat. the mass be mixed in-a liquid'pr semi-liquid condition; and the plastic mass resigltant is very handled divided into particles of any size and shape; and the moisture pervad ng the mass also greatly decreases any liability and tendency to accidental explosion. In the process of the third application cited the liquids of the molasses provided sulficientmoisture for working the materlal. But the water present must. subsequently be removed to form a dry product.
one third "of. the amount *0: chlorate; by weight; For instance,- if I use seventy five poxmds of chlorate, then I- typically use abont'twelv'e and one' half pounds of the starch and about twenty five pounds of'molasses. (This "amount of molascs is based onthefa'et-that i1i-so1ne cheap-hcet sugar-- molasses the amount of, available carbohyd-m'tes is only ahoilt one half of the total nmlas's'es; in molasss where the mlrlm-hydmtes run to a higher proportion. the lolalamount of-molasses used would be proportionately smaller.) Allowing one half o'f'the molasses forsubstances which will not enter into the re-action, substances other than carho hy- -draltcs. there is thorn in the compound above outlined a total'of twenty five pounds of carbo-hydrates. This makes the ideal pro- 1 portions of one part carbohydrate to three p'arts chlorate.
In connection with the above enumerated ingredients I hate found a special ellicieucy in the'combination of certain amountsoi calcined clay. l-ortland cement, or like sub stances? :1' have found by repeated e. eriment that :1 small amount of potass um chlorid is left in solid state afier the detonation of a mixture of chlorate alld' carho-h v- (Irate: and that increasing additions of some silicate materialdecrease thesolid deposit. I have also found, with my general class of chlorate and carbo-hydrate explosives and particularly with one. herein descrilur-zl. that 110 an addition f the silicate material up to an amount of forty pounds (In the amount of other substances given above) does not materially decrease the explosive energy of a givenweight-of explosive; that is specifically,"thata pound of explosive containing the proportions 7 5 chlorate, 12% starch, molasses and clay is approximately as strong as a pound containing thepropon.
tions 7 5 chlorate, 123,- starch and 25 molasses. From these facts I have arrived atthe obvious conclusion that the silicate must carry with it some. potential explosive energy to balance the energy of the chlorate and carbo-hydrate displaced. It seems that the alu- '15 react w1th -potass1um and chlorin to form other compounds and liberate oxygen. This 4 active chemical action is in addition to the 25. Anysubstanoe of a general character simiminum silicates of calcined clay, or silicates ofother materials such as Portland cement,

Calcined clay seems to give best results,-
carrying a 'high percentage of aluminum silicates. Portland cement is veryconven iently used, however, as it can be readily obtained on themarket in dry powdered form.
lar to these will give good results, it being apparent that the presence of silicates adds 'j'to the explosive. energy.- ;The other comso act mainlyfas heat retainers. IThis actionis; I ofno'httle importance, as theheatis' "thus jmorejhighly concentrated in'jthe-ex '35 ggases, generated by the explosion.

The grains are smoothed exteriorly so as to reduce friction both "in the operations of mix1 the ingredients and-handling the finished explosive. The carbon also enters into the chemical action 'of detonation.
It is in the process of manufacture of this particular explosive that it has one of the greatest utilities. As a preparatory measure 1t isonly neoesary that the chlorate and the may -.be' pe r'formed indifierently). starch not-necessarily liquefied, heated or dissolved thoro Starch be firstifinelydivided. The chlorate, starch, molasses, and clay or'cement are then all mixed together in a suitable mixing ma chineT-a' suitable amount of graphite or similarstanceis added and the mass is then divided and dried in any suitable manner.
