Beit known that I, HENRY D. WHIrrLn, a citizen of the United States of America, residing at Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvements in Reinforced-Concrete Retainlng-Walls, of which the following is a specification.

This invention relates to certain new and useful improvements in concrete bulkheads or retainingwalls; the object being to pro-.

vide a sectional retaining wall formed of a plurality of piling units so constructed that they can be readily driven into position or sunk by the method now in'use, whereby an exceedingly strong and durable Wall will be formed, and one which is especially adapted to be used for forming a protection for levees, in order to form a sectional core for the levee to prevent craw-fish from working transversely through the levee.

Another object of my invention is to pro- .Vide a sectional-reinforcing wall in which each of .the piling units is formed of a member having an obliquely cut-01f beveled penetrating end which can be readily driven into position, and onewhich will clean its way as it is forced down into position against .the' adjacent unit whereby an exceedingly tight joint is formed between the units; said units being staggeredly arranged in order to form lap-joints; the crevices ofwhich will soon become filled with the earth or sand in which they are driven in order to form a water-tight wall.

A still further object of the invention is to provide a sectional reinforced retaining wall, which can be used for forming jetties, breakwaters, sea walls, dams, and for various other purposes; each section of the wall constituting a piling unit with a reinforced or metal penetrating point in order to prevent the concrete from chip-ping when brought into engagement with an obstruction.

Other and further objects and advantages of the invention will be hereinafter set forth by the cordance with my invention, showing the application of the same 'to a levee; Fig. 2, is a longitudinal horizontal section through the same, showing the manner of arranging the sect-ions in respect to each other in order to form lap-joints; Fig. 3, is an end eleva- Specification of Letters Patent.

tion partly in section; Fig. 4, is a vertical longitudinal section of a portion of one of the piling units; Fig. 5,'is a detail perspective of the starter and one of the units, showing the manner of forcing the unit into position; and Fig. '6, is a detail perspective view of the pointed ends of a Series of pilin units.

Li e numerals of reference, refer to like parts in the several figures of the drawings. In carrying out my invention, I employ a plurality of right and left piling units 1 and 2, which are formed rectangular in cross-section having a metal reinforcement 3 preferably formed of electrically welded wire mesh arranged, as clearly shown in Fig. 4. These units can be molded in an ordinary concrete mold, and can be formed of any size desired, and-I preferably construct the units in the form of a slabwith its lower end beveled and cut-off obliquely,

so as to form a tight ]",0iIlll; said penetratin'g point cleaning the abutting surfaces of the adjacent units asit; is forced downwardly by the peculiar shape of'the penetrating point. l

In order to protect the pbnetrating point when working in rocky cou tries, I provide a galvanized metal cap 5 having its lowerend cut-off obliquely and beveled conforming in shape to the penetrating point of the" piling unit, and preferably secured in position by transverse rivets, as shown at 6.

These caps are preferably counter sunk in the units in order to obtain a flush face upon all sides, so that when the units are arranged in position, as shown, they will fit snugly against each other. The great trouble in forming concrete retaining walls of this nature, now in use, is in handling the material or the units constituting the retaining wall, and I have found that by constructing the units the shape shown, an exceedingly strong and durable retaining wall is formed and-one which can be constructed at .a very low cost as the units can I am aware that I am not the first to provide a retaining wall of piling. units, but

the walls hereinbefore constructed have not proved successful sofar as I am aware as in sinking the units it was impossible to maintain the close relation of the units that is essential in forming a retaining wall, while with my construction of penetrating point, the units are forced together as they are sunk into position.

In constructing a retaining wall of a plurality of units, as hereinbefore described, a starter l0 constructed substantially the same as the units with the exception of a vertical shoulder 11, is first sunk into position and a left unit is placed against the same and sunk into position, and then a right unit is placed upon the opposite side and sunk into position, this being carried out until the desired length of wall is-formed;the right and left unitsbeing' staggeredly arranged so that a lap-joint is formed, and it will be seen that as the unit is forced downwardly into the corner formed by a pair of the transversely sunk units, the chiseled point will clean the earth out of the corner as it is forced downwardly, allowing the units to be set tightly against each other; the peculiar shape of the point forcing the unit being sunk tightly into the corner and against the adjacent units, which is the essential feature of my invention, as I have found that unless a piling unit has a point which will force the unit in two directions, as it is forced into ground, it is impossible to construct a retaining wall of a plurality of units which will be practically water-tight, as the units will sheer oil to one side and will not maintain their close relation to each other, as is necessary.

It will be seen that by arranging the units in a staggered manner, the point, for instance of the right unit, will be at the center of the left unit, or vice versa, allowing the earth to be compressed or forced aside as the units are sunk into, position.

In order to strengthen the top oi: the units and to maintain the same in their proper position, I provide a cap 7 formed of reinforced concrete which is also formed of sections; the reinforcement employed being of electrically welded wire mesh, as shown at 8. The upper ends of the piling units are preferably secured together by transverse v bolts 9, passing through registering openin s formed in the units as shown, and while I ave only shown a sin is cap unit, it is of course understood that t ese capsare to be formed of such a size that they can be handled readily, or they can be molded over the units, audit is not essential that they be secured in position, as they will maintain their proper positions upon the piling units by their own weight and shape, as they straddle the top of the units which is clearly shown in the perspective view and the horizontal section.

eeann From the foregoing description, it will be seen that I have provided a sectional reinforced concrete retainin wall, which. isformed of a plurality of right and left units staggeredly arranged in order to form lapjoints said units having penetrating points which force the unit as the same is being sunk in two directions, in order to forms compact wall when completed, which will have all of the advantages of a solid wall.

In the specification I have used the terms right and left units which is to define thatunits are used in which the penetrating points of one set of units are beveled-reverse to the bevel portion of the other set of penetrating points which is essential in the con-. struction of my retaining wall.

I claimi 1. A reinforced concrete retaining wall formed of a plurality of staggeredly arranged pilin units having oppositely obliquel cut-o beveled penetrating points.

" 2. g reinforced concrete retaining wall formed of a plurality of piling units staggeredly arranged,v each unit having an obliquely cut-oil beveled penetrating point, the bevel of the points of the right units being reverse to the bevel of the points of the left units.

3. A. sectional reinforcedconcre'te retaining wall formed of a plurality of piling units each unit having an obliquely cut-0' beveled penetrating point, said units being staggeredly arranged, and a cap arranged over the top of said units.

4:. A piling unit for retaining walls, comprising a remforced concrete member substantially rectangular in cross section having a cap at its lower and formed of galvan ized metal cut-oil obliquely and beveled.

5. A sectional reinforced concrete retains ing wall having smooth side faces. said wall being formed of parallel rows of abutting piling units staggeredly arranged, each pilmg unit having its lower end cutoff obliquely and beveled, and a cap arranged over said units and secured in positionthereon.

6. A sectional reinforced concrete retaining wall formed of a plurality of piling units staggeredly arranged side by side, each unit having a penetrating point cut oil obliquely and beveled for forcing the same longitudinally and laterally in position against the adjacent units, the bevel of the points of one set of units being reverse to the bevel of the points of the other set of units.

In testimony whereof I affix my signature in presence of two witnesses.
