This invention relates to the treatment and use of city refuse for the filling-in of mud flats.

The refuse collected in most cities comprises a large proportion of old paper, cardboard boxes,

f 5 and the like, as well as food refuse and other fermentable ingredients and other waste products,

and the disposal thereof involves considerable ex-Y pense to many cities.

Many mud ats, due to one cause or another,

V give off very disagreeable odors, this being sometimes due to deposition of sewage by receding tides in the case of tidelands, so that land,v

'20 and is co-ordinated with the solution of the other.

Another object of my invention is to make useful disposition of city refuse.

Another object of my invention is to use city refuse in such manner that it will become an asset of value to the city which otherwise had the problem of disposing thereof. i

Another object of my invention such manner that it will convert a liability into a valuable asset.

Another object of my invention is to use such refuse for filling in such mud flats.

Another object of my invention is to do away with the odors arising from such mud ats.

is to use it in municipal Another object of my invention is to lill in and 'to make of suchmud flats good land useful for ordinary municipal purposes such, for example, as building lots, streets, parks, and the like.

Another object of my invention is to fill in such mud flats with such municipal refuse in such 40,manner that it will not only be odorless, but free of rats, flies and vermin in general.

Other objects of my invention will become apparent on reading the appended specification, taken in connection with the appended drawing g which lforms a part thereof.

The figure of the drawing is a vertical sectional view of a completed fill made according to my invention.

In some cities no separate storage and collection are made of dry garbage and wet garbage, but all garbage is collected merely as one item. According to my invention, such garbage is thoroughly soaked with water, preferably salt water if available, and a layer thereof about four feet vthick is laid at low tide on the mud, this being rolled with a'twelve-ton roller to compress it, thereby reducing it rto thickness of about two feet. The refuse may be wetted with the water before ,or after spreading in layers, as may be desired,

but I generally prefer to wet it before spreading. 30

On the drawing the mud is illustrated at 10 andthe compressed refuse layer at 11. This layer is'then covered with a layer of oil, preferably asphaltic oil, although any oil may be used which will not impart a disagreeable odor when the 65 work is completed and which will tend to repel rats, flies and other vermin. A layer of earth of about six inches to one foot thick is placed thereover, and this is rolled, preferably with a twelve-t0n roller, to produce the layer 12.

Thereupon, the above set of steps is repeated until the desired height is obtained; that is, a layer of refuse 13 is providedon the layer 12, and layer 13 being similar to the layer 11 and being treated in the same manner by wetting, rolling and oil application, and a layer 14 is provided on the layer 13,y this layer 14 being similar to and produced in the same manner as the layer l2. I have illustrated on the drawing only one repetition of such steps, but the number thereof will be determined by the depth of ll desired.

On top of the whole a thickness of earth is placed which will yield a thickness 15 of about two feet when solidly compacted, it being compacted by rolling, preferably with a twelve-ton roller. Thereupon it is rolled with a twelve-'ton roller having spikes about six inches long in the wheels thereof, and a surface coat of hot oil is then applied which is allowed to soak in for twenty-four hours; whereupon it is rolled with a twelve-ton roller Without spikes which seals the top surface.

The method as described above may be applied to slimy mud flats without causing mud waves as does a heavy rock fill. r I'he salt water is used for the purpose of softening the paper, cardboard, boxes and the like which gives a greater tendency thereto to be compressed and compacted by the roller. Fresh water may be used in place of salt water, but I prefer salt water when available. v

Fills on mud flats made according to my method will carry a sixty-ton steam shovel or other object without any indentation of the surface and, in fact, they will carry a locomotive with a train of freight cars loaded Ato full capacity. A seven-ton truck loaded with seven tons of earth can travel over the surface at a rate of twenty miles an hour.

My invention provides a way for advantageously disposing of city refuse as a Whole, thereby avoiding the requirement of separating it into or keeping separated the dry and Wet components, so that it results in simplifying the collection ofthe refuse in that both kinds can be stored by the householder in one container and removed in the same conveyance.

in some cities the dry garbage is collected separately from the Wet garbage, that is, paper, cardboard, ashes and other solid dry refuse is collected separately from the Wet garbage which may contain refuse such as fatty and other food matter, melon rinds, fruit and vegetable pulp` or skins, and other like material. However, if certain municipalities should desire to collect the Wet refuse and the dry refuse separatelynboth the Wet and the dry may be used according to my invention or, if desired, only the dry refuse may be so used.

Ix/iy invention has an additional advantage for use in districts Where there are unimproved and Luidesired hills, since it provides for disposal of `the earth obtained in grading such hills inasf posing of municipal refuse containing Vmaterial made of paper pulp, which comprises providing on said mudiiats a substantially four-foot-thick layer-of said refuse soaked with salt water, rolling said four-foot-thick layer with a twelve-ton roller to a thickness of tvvo feet, covering said resulting layer with hot asphaltic oil, covering said oiled layer with earth to a thickness of from onen half foot to one root, then rolling with a twelveton roller, building up on said laminated nil sol iprovided by repeating the above mentioned sequence of steps until the desired thickness of fill attained, locating on top thereof a twofootthick layer of solidly compacted earth, rolling the surface thereof with a twelve-ton roller having six-inch spikes, applying hot oil to the spiked surface and permitting the same to soak in for twenty-four hours, and then rolling the surface with a twe1ve-ton smooth roller. g

2. rThe method of filling in mud flats and disposing of municipal refuse containing material made of paper pulp, which comprises providing on said mud ats a layer ci said refuse soaked with water, compressing said layer, covering the resulting compressed layer with oil, covering said oiled layer with earth, and compressing said earth.

3. The method of filling in mud flats and disposing of municipal refuse containing material made of paper pulp, which comprises providing on said mud flats a layer of said refuse soaked with Water, compressing said layer to about onehalf its thickness, covering said resulting layer with oil, covering said oiledlayer With, earth and compressing said earth, building up on saidlaminated fill so providediby repeating the above^mentioned sequence oi steps until the desired thick` ness of fill is attained, then locatingontop'there-- of a layer of solidly compacted earth, perforat the surface of said topmost layer, applying cil to the perforated surface and permitting the sarnevto soak in, and then smoothingoverthe surface.

4. The method of filling in mud flats and disposing of municipal refuse containing material rmade of paper pulp, which comprises providing quence of steps until the desired thickness of iill.

is attainedgthen locating on top` thereof Y a layer of solidly compacted earth, rolling andperfo'rate ing the surface of said topinost layer, rapplying oil to the perfcratedsurface and permitting the' same to soak in for twentyafour hours', and then Q rolling the surface.
