METHOD OF BUILDING LEVEES AND EMBANKMENTS.

Application filed October 14, 1915.

To all whom it may concern:

Be it known that I, Ansimn PERRILLIAT, a citizen of the United States, residing at New Orleans, Orleans parish, State of Louisiana, have invented certain new and useful Improvements in Methods of Building Levees and Embankments, the following being a full, clear, and exact disclosure of the one form of my invention which I at present deem preferable.

For a detailed description of the present form of my invention, reference may be had to the following specification and to the accompanying drawings, which illustrate my invention.

My invention relates to a method of building levees and embankments particularly designed for use in cases where the material for constructing the levee or embankment, or enlarging an old one, must be taken from an extremely wide and shallow borrow-pit by means of an excavator of the rotating derrick-boom type.

Referring to the drawing, 1 haveindicated at the left of the figure a levee L which, in this particular illustration. is in the nature of a levee to be enlarged to the extent indicated at E and the material therefor must be excavated from a wide pit extending from the levee to the extreme right of the drawing.

I first station an excavator X of the aforesaid type at the point A which is at a distance from the outer edge of the pit about equal to the radius of action of the machine. From this point A the excavator is moved from time to time, first along a straight route toward the levee up to a point A then backward along a diagonal route to the point A and so on to thesuccessive points A*, A A, etc., as far as may be desired. This zig-zag path of travel of the excavator I have indicated by the parallel lines bounding the two sides of the path and showing the width of path required by the excavator. The distance between the centers of each of the straight parallel portions of the aforesaid route is equal to the horizontal reach of the excavator less one-half the width of the required trackway.

In the travel of the excavator from A to A it first excavates, while still at the station A along the extreme right-hand edge of the borrow-pit area bounded by the four points a a a ,.a and dumps the ma- Specification of Letters Patent.

terial therefrom along the extreme right hand edge;of the dumping area bounded by the four points (Z al (Z (Z It then proceeds to excavate progressively from right to left within the said excavation area, leaving untouched however its diagonal track from A toward A and dumps the material progressively.from right to left over the said dumping area. When that has been completed the excavator is moved along the diagonal path from station A to station A It then excavates from right to left over a second excavation area bounded by the four points a a a (i leaving untouched however its own path toward station A and deposits the material progressively from right toleft over the second dumping area bounded by the four points (Z (Z (Z (F. In addition ,it excavates it. own path behind it which had been left while it was excavating in the first area. In like manner the machine is moved. next, to station A from which it is moved step by ste,

to station A while it digs within the third excavation'area bounded by the fourpoints a 0. a a and deposits the n'iaterial in the third dun'iping area (Z (Z cl, (Z .This creates a temporary pile of material covering the several dumping areas. When this has been continued as far as desired, the excavator is moved across the lower end of the temporary pile to the station 13 near the line to which the completed levee will reach. will excavate progressively, but in this case from left to right, over the areaembraced by the four points 0 c 0 0 including the third dumping area aforesaid and depositing the material on that part of the levee-extension between the four points Z Z Z Z It will be observed that the temporary dump aforesaid has been 'established on an area which is to be subsequently excavated and that part of the material which has to be twice handled includes only that from the farther part of the pit while its second handling occurs in connection with the excavation of the nearer part of the pit. The machine then proceeds with its operations and is gradually brought to station B respecting however its track ahead of it and digging up its track behind it. From 13 the excavator is moved diagonally from B to B where it begins to excavate, progressing from left to right,

From this station E the machine ceeds in a' the area within the points 0 0 0 0 including the dump (Z cl, (Z and to deposit the sameon the levee Within the area Z Z Z lflbut leaving its trackwayahead and digging up its trackway behind. like manner the final areac c 0 0 including the first dumping area aforesaid, is excavated and delivered on the area Z Z Z Z of the levee.

It will be now apparent that by this method a very wide and shallow borrowpit may be utilized to build the levee, without resort to other apparatus than an ordinary excavator having aworking radius of practicable length.

hile I have described the operation as progressing from right to left, or, from left to right, such description is only illustrative, since, in either case the progress may be in the opposite direction. The essential feature is that the excavation proline transverse to the line'of the levee or embankment, progressing either toward it or away from it, and from the end 'of one series of such transverse exc'ai' ations the. machine is moved to the beginning of the next series.

1 WVhat I claim as new and desire to secure by Letters Patent is:

1'. T he method of building a levee or embankment. which consists in excavating progressively at a series of points, in a di rectiontransverse to the line ofthe levee or embankment, the remoter portion of a berrow-pit; depositing, in a corresponding progressive manner, the material thus excavated at an intermediate point of the pit; then excavating at a series of points also in the said transverse direction and progressively, the nearer portion of said pit including the above mentioned material, and

Copies of this patent may be obtained for finally depositing the material last excavated on the levee or embankment.

2. The method of building a levee or embankment, which consists in excavating progressively at a series of points, in a direction transverse to the line of the levee or embankment, the remoter portion of a borrow-pit; depositing the excavated material progressively on an intermediate unexcavated area of the pit and in a line parallel with the levee or embankment, then excavating at a series of points, also in the said transverse direction and progressively, the nearer portion of said pit including the material above mentioned, and finally depositing the material last excavated on the levee or embankment.

3. The method of building a levee or embankment, which consists in excavating in on a succeeding portion of the pit in a direction parallel with the levee or embank- 1 ment; then excavating in a similar series of arcs the nearer portion of the pit, including the material previously excavated, and depositing the material on the levee or embankment. p

In witness whereof I have hereunto set my hand, this fourth day of October, 1915.
