Specification of Letters Patent.

Patented March 2, 1909.

To cl; whom it may concern:

Be it known that I, HEINRICH Orro BRANDT,

Germansubject, and resident of Manchester,

county of Lancaster, England, have invented certain new and useful Methods and Appa-v ratus for Atomizing and Spraying OilyMaterials,.of which the following is a specification. Itis well known that oily materials such as petroleum, heavy coal tar oils, and other similar oily materials have been'applied to roads, to the permanent ways of railways to mine galleries and other places or surfaces for purposes of disinfection, for preventing the rlsing or scattering of dust into the air, and for other purposes.

Difficulties are encountered however in the application of such oily materials. to roads and other surfaces such as those mentioned above owing to'its not being easy to apply or distribute the .oily material in a su ciently fine state of sub-division and in sufiiciently small quantities to achieve the purposes indicated above without incurring the disadvantages caused by distributing the oily inaterial unevenly'or in too large Attempts have been made to overcome these difficulties by converting the oily ma'terialinto a more or less-permanent emulsion-with "water by the aid of. some volving the necessity of previously prepar-' emulsifying agent and applying the emulsion either with or without previous dilution with waterto the road or other surface to be treated. In the preparation of these emulsions however, it is necessary-to use a sufiicient proportion of an emulsifylng agentto ,make the resultlng emulsion so permanent that it maybe trans orted and kept during a moreor less inde nite time without the component oily'material and aqueous solution separating to such an extent as would be deleterious to the ultimate'purpose for which the emulsion is to be used. The preparation of emulsions possessing the requisite de ree of stability involves considerable cost.

he present invention is for the purpose of applying oily materials in a very fine state of subdivision and in quantities which can be accurately regulated to any surface such as that of a road,or a railroad permanent way, of a mine. gallery and the like without in ing storing. and transporting an emulsion of the oily material wlth water or with an aqueous solution.

" My invention consists in reducing the oily material to a fine state of sub-division by the aid of any convenient appliance (such asa rotating drum or disk or a jet of steam or compressed air) attached to the portable apparatus which distributes the oily material upon the road or other surface and'immediately the oilymaterial has-been reduced to such fine state of sub-division throwing it out upon the road or other surface by the aid of a spray, jet or stream of water. By this method of rocedure the oily material is retained in a ne state of sub-division during a length of time suflicient for it to reach the road or other surface to which it is to be 'applied before the particles of the'oily material coalesce orcondense together and before the oily material thus separates more or less completely from the water oraqueous solution in which-it is suspended in a finestate of sub-division.

- tudinal section showing a modified construction. Fig-,4, transverse section ofsame.

My inventionfis applied inv a simple form by the aid of a watering or distributing cart or other portable a paratus constructed with reservoirs or tan A and B, one or more tanks Ato contain Water and one or more The tank A is provided with adelivery valve a and the tanks B to contain oily material.

tank B with a delivery valve b bywhich the speed at which they discharge their contents can be accurately adjusted at any desired rate., The apparatus is also provided with a centrifuge or rapidly rotating drum 'D into which the contents of thereservoirs A and B are discharged by the delivery valves a and b at regulated rates. The druinD is driven from the axle 'ofthe. portable apparatus by suitable gearing or otherwise (see Figs. 1 and 2.) The purpose and action of the contrifuge is to reduce the oily material to a fine state of sub-divisionan'd to mix it with the The drum centrifuge D in which the oily material is reduced to a line state of subdivision may be replaced by a rapidly rotating disk D upon which the oily material is allowed to fall from the delivery valve (see Figs. 3 and 4'). The horizontal circular metal disk D upon which the oily material falls is rotated at a high rate of speed about a vertical axis by means of a driving arrangement actuated from the axle of the distributing cart or otherwise. The disk D? is inclosed in an annular chamber f by a casing F around the periphery oi which the Water l'romthe tank A. is admitted through the delivery valve a by a .pc-wrioratcd pipe a. As the oily material falls upon the rotating disk D it is immediately thrown oil in a fine state of sub-division, upon the sides F of the annular chamber down the sides of which water from the water reservoir A is caused to flow at a regulated rate. The lincly divided particles of oily material. are swept away by the stream of water into suitably arrrmged distributing pipes lil from which the mixture of oil and water is discharged onto the road or other surface.

The appliance for finely dividing the oily material may be driven by a i-icparate motor or in any other way which may be found convenicnt in place of being driven from the axle of the watering or distributing cart. Thus with a watering cart or the like driven by nlechanical or electrical motive power it may be convenient to drive the centrifuge or like appliance by the aid of a separate motor driven directly from the main supply of mechanical or electrical power.

The Water may be replaced by aqueous solutions such as sea water; chlorid of lime solution or other solution. of disinfecting or deliquescent substances or the like and when l'ound desirable one or more than one oily material may be reduced to a fine state oil sub-division and distributed upon the road or other surface after admixture with one or more aqueous solutions in the same portable appliance.

The inventor has found that ii the water or aqueous solutions used in the abovedescribed methods of applying his invention are mixed with the oily materials in the manners described. above while at a temperature above the ordinary atmospheric temperature the admixture between the oily material and the aqueous solution and the reduction and maintenance of the oily ma terial to and in line state of sub-division are promoted.

What I claim as my invention and desire to protect by Letters Patent is:

1. The method, of atomizing and emulsify' ing oily materials and applying same in a fine state of subdivision-to road and other surfaces, comprising the dividing up of a small volume of the oil, drop by drop, by suitable revolving mechanism and carrying the same forward inthe subdivided state by min-11s of a large volume of an aqueous liquid substantlally as described.

2. The method oi atomizing and emulsifying ily materials and applying same in a fine state of subdivision to road and other surfaces which consists in supplying the oily material, drop by drop, rapidly atomizing the drops successivcl y by mechanical means,

carrying the atomized material forward by a large volume of aqueous liquid and a plylng the emulsion so formed directly to t 1e road before the oily atoms can coalesce substantially'as described.

3. The method of atomizing and emulsifying oily materials and applying same in a line state of subdivision to road and other surfaces which consists in pouring a small volume of the oily material drop by drop into a rapidly revolving mechanism by which it is atomized, carrying: the atomized material forward by a large volume of aqueous liquid and applying the emulsion so formed directly to the road before the oilyatoms can coalesce substantially as described.

4. Apparatus for atomizing and emulsifying oily materials and treating roads and other surfaces therewith constructed with separate reservoirs for the oily material and for an aqueous liquid, delivery valvcsto deliver the oil and water in the desired prolportions rapidly revolving mechanism by W rich the oil as it drops is atomize and pipes to distribute the admixture of x lllGl and oily material substantially as hemobefore de-' scribed.

5. Apparatus for atomizing andjcmulsily ing oily materials and treating roads and other surfaces therewith constructed with separate reservoirs for the oily material and for an aqueous liquid, delivery valves to deliver the oil and water in the desired proportions', it rapidly revolving drum by which the oil as it drops is atomized, and pipes to distribute the admixture of water and oily material substantially as hereinbefore described.

In witness whereof, I have hereunto si ned my name in the presence of two subscri ing witnesses.
