PBDCESS AND APPARATUS 0F TREATING MATERIAL.
Application filed. May 16,
To all whom it may concern:
Be it known that I, JOHN E. CLARK, a citizen of the United States, residing at Toronto, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Processes and Apparatus of Treating Material, of which the following is a specification.
This invention relates to mixing machines,
One object is to provide a machine for mixing asphaltic fibrous, cementitious, earthy or mineral, or other materials alone or two or more together or compounded with bitumen or asphalt in an economical and convenient manner under the influence of heat maintained at a uniform temperature.
Another object is to provide a portable mixing machine particularly adapted for the mixing of paving materials in the presence of heat, such for instance, as fibrous material withbitumen or asphalt, or earthy or mineral material with bitumen or asphalt, or fibrous materials with earthy or mineral matter and bitumen or asphalt, embodying among other characteristics, means whereby the material may be discharged from the mixing vat onto the ground or. discharged from the vat into a storage chamber arrangedbeneath the vat where it ma remain indefinitely or from which it may e trans ported to another place and malntained at substantially the same temperature under which it was agitated in the mixing vat.
Another object residesinthe provision of a mixing machine particularlyadapted for mixing moist materials embodylng a mlxlng vat in which the moist materials may be agitated and thoroughly commingled in the presence of heat and bitumen or asphalt and 1nto which vat heated air may be forced to assist in facilitating the drying of the materlals, p
Withthe'above and other objects in VIEW, the present invention consists in the COII1 b1-" nation and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details Specification of Letters Patent.
Patented Dec. 28,192fi, 1916. Serial No. 97,934.
Fig. 4 is a top plan view partly in hori- I zontal sectlon lllustrating a modified form of the invention.
Referring now more particularly to the accom anymg drawings, the reference character indicates a hollow frame composed of any suitable material and of any suitable size and shape, preferably rectangular in formation, as showrnand, if desired, mounted in any preferred manner on suitable Wheels 10 whereby the machine may be readily transported from one place to another.
A mixing vat B is supported on the wheeled supporting frame in any suitable manner as, for instance, by means of a suitable framework 11. This yat is relatively long and preferably double walled so as to provide air spaces 12. v 'The outer wall 13 of the vat may be formed of relatively heavy material while the inner wall 14 of the chamber is preferably constructed of light material there bein a plurality of perforations 15 formed in the inner wall of the vat adjacent opposite sides of the longitudinal discharge opening 16 formed throughout the length of the bottom of the vat, the perforations being formed for a purpose presently explained.
The vat B has communication with a storage chamber 17 through the aforesaid open ing 16, the chamber 17 being formed by walls 18 and 19 depending from the bottom of the chamber and at their lower ends secured in any suitable manner to the framework A of the wheeled supporting means.
means 23. For instance, materials may be discharged from the mixing vat B through the opening 16 upon an outward pull on the slide 20 and discharged into the storage chamber 17 and transported from one place to another. If desired, both slides 20 and 22 may be pulled out and the material permitted to pass from the mixing vat B directly through the storage chamber 17 and through the framework A and onto the ground, or into a receptacle or conveyance (not shown) for the transportation of the material.
Located on the wheel supporting means are furnaces C arranged preferably on opposite sides of the storage chamber 17 beneath the chamber B. Each furnace has a grate 24 and access may be had toeach furnace in any suitable manner, the construction of the furnace being immaterial so long as it is capable of heating the material in the vat B and in the chamber 17 and maintaining the materials therein at a uniform temperature, it being one of the objects of the invention to maintain the material carried in the receptacle 17 at the same uniform temperature it had when in the vat B.
'Cylinders 25 are supported in the upper portion o'f each furnace C to receive air let into them through header pipes 26 leading by pipe connections 26' from a pump 27. This pump may be of any suitable character designed for forcing the air under pressure into the cylinders 25 and may be located on the wheeled supporting means or remote from it. Each cylinder 25 has a pipe 28 leading from its inner end upwardly along the outside of the outer wall 13 of the mixing vat and has its upper end directed through the outer wall 13 and fitted in the inner wall 14 of the mixing vat so that the air under pressure heated in the cylinders 25 by the respective furnaces may be forced through the pipes28 into the vat at the top thereof for the purpose of facilitating drying out the moisture in the moist material and for the purpose of expediting the drying out process and for forcing the moisture out of the mixing vat B through the opening 29 in the top 30 of the vat and which opening 29 may be closed by closure 31, if desired, to heat the interior of the vat.
Located in the air spaces 12 between the outer and inner walls 13 and 14, respectively,
of the mixing vat Band disposed in the line of each of the aforesaid pipes 28 is a valve 32 having a valve stem accessible for manipulation to operate the valves 32 so that all of the heated air from the cylinders 25 may be directed into the mixingchamber at the upper portion thereof or so that all of the heated air from the cylinders 25 may be (lirected into the air spaces 12 and permitted to enter the mixing vat B at the bottom thereof through the aforesaid apertures 15, and thereby be forced upwardly through the mass; or, if desired, the valves 32 may be so manipulated that the air under pressure may be divided, whereby a portion of the air under pressure may be directed into the vat B at the upper portion thereof and a portion permitted t enter the air spaces 12 and enter the vat B at the bottom thereof through said apertures 15.
As has been stated, one of the objects of the present invention is to mix materials for paving purposes. In practice, I may mix moist fibrous materials with bitumen or asphalt. I contemplate also the mixing of moist mineral matter with moist fibrous material and bitumen or asphalt. I contemplate also the mixing of moist claywith or without lime mixed therewith and bitumen or asphalt, as Well as the mixing of moist clay with or Without lime, and moist sand with bitumen or asphalt, as well as the mixing of all of these materials, mixing the same in thepresence of heat applied exteriorly to the mixing vat B through the instrumentality of said furnaces and to facilitate the drying out of the materials by the injection of heated air under pressure into the mixing vat. I contemplate also thoroughly agitating the materials during the process of mixing and this agitation may be accomplished tion is subjected to hot bitumen at a desired degree of fluidity in the mixing vat B and agitated therein a predetermined time by the agitators 35. This fibrous material and the bitumen or asphalt may be placed in the mixing chamber B through the long opening 29 normally closed by the long closure 31. Before the bitumen or asphalt is placed in the vat B, the furnaces C are put into operation to heat the vat so that the temperature of the bitumen or asphalt may be maintained at the proper temperature.
I first place the damp or moist material in the vat and close the door 31. I then subject the moist material to the action of the hot air under pressure to warm the same, keeping the door 31 closed to prevent drying of the material. At a predetermined time I open the door 31 and introduce the desired amount of hot bitumen or asphalt and leave the door open to permit the escape of steam generated by the mixing of the hot bitumen aeeaeao or asphalt with the moist material. The material before or after the introduction of the air or bitumen or both, may be agitated to efi'ect a thorough mixing of the contents of the vat.
After the material has been thus treated, the slide 20 may be pulled out to permit the mixed material to drop into the storage chamber 17 in which it is maintained at a uniform temperature by virtue of the disposition of said storage chamber between the furnaces C and be ready for use when needed; or, if desired, both slides 20 and 22 may be pulled out and the material permitted to drop from the mixing vat B entirely through the storage chamber 17 onto the ground for immediate use. The material is preferably laid for paving purposes before it cools andwhile still hot, it is subjected to pressure by rolling or otherwise. The result is an economical pavement possessing long life. sanitary and other valuable qualities.
The same process of treating the material is again gone through with 1n the mixing of moist sand with bitumen or asphalt, the.
only difierence being that the sand does not necessarily become impregnated, although the bitumen or asphalt forms an effective binder. The same process is gone through with in the mixing of moist fibrous matter and moist sand with the bitumen or asphalt, as well as when moist clay alone or with lime or with fibrous or other materials is subjected to the action of heated bitumen asphalt.
No matter what material or materials may be employed as a body, the same is preferably moist and, if it is not sufficiently moist in its natural state, the same may be dampened with. water.- I find that by the use of moist material instead of material that has been previously dried, that I am enabled to obtain a better impregnation in materials capable of becoming impregnated and that I provide for a'more efiective binding of the materials together whether the material is such as to become impregnated or not.
The materials thus treated may be used for roofing, flooring, railroad ties or other usages as well as for paving purposes. However, the machine is particularly adapted for use in laying pavements as the materials may be mixed and prepared for use at any point along the road, obviating the necessity of hauling the treated material from a distant plant, and also obviating the use of the ordinary drying apparatus.
In Fig. 4 there is illustrated a modified form of the invention. In this modification the shafts 34: and the bolts 35' may be hol-' low and the pipes 34 which convey the compressed air from one or more heating chambers 25' located in one or bothof the furnaces are connected to the ends of the nection of both of the hollow shafts in Fig. .4 with two tubes leading'to one air heating chamber 25 is merely to disclose one em bodiment of the present invention.
