le it known that I, ROBERT HART BOLEN, citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Molds for Forming Sunken Concrete Structures, of which the followin is a specification.

The invention relates to the construction of concrete walls; and it has for one of its obj-cots to simplify and cheapen the cost of construction of this type of wall.

Another object of the invention is to pro vide a novelly-constructed hollow pile, which can be driven into the ground, and which, when filled with concrete, may be readily withdrawn and again driven, filled with concrete, and withdrawn, the operationbe ing repeated until the required length of wall has been constructed.

Still another object of the invention is to provide for the construction of circular and angular walls.

1n the drawings-Figure 1 is a perspec live view of my improved pile Fig. 2, a transverse, longitudinal section of the same; Fig. 3, a horizontal, transverse section through the upper end of the pile and the driving-box; Fig. 4, a top plan view of a series of the piles interlocked together; Fig. 5, perspective view of the driving-box; Fig. 6, a similar View of one of the hook shape guides; Fig. 7, a horizontal section through the upper end, and driving-box of a modified form of pile; Fig. 8, a similar section through the lower end of the same, and Fig. 9 a plan view of a detachable bottom for the modified pile. Fig. is a plan viewof the bottom portion of the structure shown in Fig. 1.

Referring to the several views, the numerals l and 2 indicate channel-irons, preferably of steel, which form the respective sides of the pile. These two channel-irons are spaced apartany suitable or required distance, with their flanges extending outwardly, and are held apart by sleeves 3, 3, ihrough which pass bolts 4 for securing the aides together. Situated at the top of the )ile within the space between the two sides,

improved pile, the first. pile s a driving-box 5, firmly bolted or riveted o the respective sides. This driving-box very much shorter than the space length :etwccn the sides, so as to leave sufficient pace at each side thereof for the entrance 1 the concrete. Each of the flanges at one edge of the pile is provided with hook-shape guides 6, (3, which are firmly boltcd or riveted to the flanges, and serve to guide all ad jaceut pile while being driven. For convenience of description, this edge of the pile will be hereinafter referred to asthe female face, the opposite edge will be referred to as the male face. The inner corners of the flanges of the male face are provided with ltn gitudinal dove- tail grooves 7, 7, and slidaliver-ranged in these grooves is a male protector-plate 8, provided atfils upper end with a hole 9 in which a line or rope may be fastened to withdraw the plate when required. The lower .end of the pile is provided with a bottom 10 hinged at one side as shown in Figs. 1 and 2, theopposite sidebcing providedwith short studs or projections 11, 11 which enter slots 12, 12 in the bottom, and serve to retain said bottom in position in starting the drivingof the pile. The lower ends of the flanges" are beveled or inclined to facilitate driving.

In the coustrm-tion of a wall, using my to be driven should be provided with male and female protector-plates, the latter plate 18, being slid into the guides 6, 6, and is left in place to form the end of the wall. Thcsecond pile with male protectorplatcs in place, as shown in Fig. 4, is then Cll.l"(3ll. l3l1 flanges of the male face being in the, g uideS 6, 6. After the second pile has con driven, the male protector-plate is witl1,cl1':1w11 from the first pile driven, leaving a clear space be tween the end female protector-plate 13 and the male proteotorplate 8 in the second pile. After a suitable number of piles have been driven in this manner, a male pro tector-platc being in place in the last pile driven, all of the othcrs-exccpt the end female plate---bcing removed, the space be tween the two plates is filled with concrete. When the space is properly filled with the concrete, the first pile and the succeeding piles are then withdrawn, the spreaderbolts proving no serious obstruction, as'thev are easily passed through freshly-mixcd concrete. On short piles, twenty feet and less in length, the spreader-bolts will not be required. The hinged bottom, as the pile is being pulled up. opens by the weight of the concrete bearing on it. Or the pile may be withdrawn, before filling with the concrete, a sutlicient distance to allow the bottom to saving open by gravity.

It will be obvious that reinforcing rods or bars may be placed within the pile before concrete is poured in, if found necessary, as-it often is in foundation work.

In driving the piles any suitable piledriver may be used, and the ordinary lead line running from the engine of the pile driver over the leads can be used to pull up the piles when required.

For constructing circular walls, and turning corners atright angles, the pile used does not differ materially from the rectangular or straight-pile, except that the sides or channel irons are curved along their longest dimensions, as shown at H and 15, Figs. 7 and 8, and when used in constructing a circular foundation or wall, four of these piles are driven in a circle, and after they are driven and the concrete poured in, the piles are pulled up and the concrete allowed to set. after'wliich the circle of earth forming the core can be removed, and if the foundation. is to support a heavy structure the hole made by the removal of the earth may also be filled with concrete. Instead'of a hinged bottom, this form of pile is provided with a detachable plate bottom 16, which is provided with upturned lugs 17, which conform to the curvature of the sides 14: and 15, 'and frictionally engage the same. Then the pile. is pulled up the plate remains in the ground.

Various changes in the detail of construction may be made without departing from the spirit or scope of my invention, and therefore I do not limit myself to the exact construction herein described.

Having thus fully described my invention what I claim is 1. fr moldfor forming concrete structures, comprising oppositely-disposed channel-irons having their flanges arranged out-- wardly, means for securing the irons apart from each oth r, guides formed on one set of flanges, a detachable closure-plate slidable in said guides, and a detachable division-plate slidable in guide-ways, formed in adjacent edges of: the other set of flanges.

2. A mold for forming concrete structures, comprising oppositely-disposed channel-irons arranged with their flanges extending out'a'ardly, means forsecuring the irons a distance apart from each other, hook-shape guide-ways formed on one set of oppositelydisposed flanges, a detachable cl0sureplate slidable in said guide ways, grooved guideways formed in the adjacent edges of the other set of flanges, and a detachable division-plate slidable in said guideways.

3. A mold for forming concrete structures, comprising oppositcly-disposed channel irons having their flanges arranged outwardly, means for securing said irons spaced apart hook-shape guide-ways formed on one set of flanges a detachable closure plate slidable in said guide-ways, grooved guidewa vs formed in the adjacent edges of the other set of flanges, a detachable divisionplatc slidable in the grooved guideways, and a driving-box ar'anged between the chan nel-irons so as to leave a pouring-space at each side thereof.
