MEANS FOR AND METHOD OF PRODUCING CONCRETE PILES.

Application led August 5, 1919. Serial No. 315,461.

T0 all 'whom t may concern.:

Be it known that I, MAURICE BLUMEN- THAL, residing at Brooklyn. in the county of Kings and Sta-te of New York, have invented certain new and useful Improvements in Means for and Methods of Producing Concrete Piles', of which the following is a specification.

1Thisinvention relates to a means for and method of producing concrete piles in the earth, the present application being a companion to my pending application Serial No. 315,460.

An object of the invention is to provide a pile having extensive projections laterally thereon, said projections, or arms, being extended into the surrounding earth so as to provide additional bearing surface of the pile against the earth to thereby increase the efficiency of the pile in sustaining such weights as may be applied to the upper end of the pile.

A further objectis to provide a pile in which the extensions, or arms, are formed of the concrete material of the pile and in which the extensions are provided with metallic reinforcing means extending into the body of the pile.

A further object is to provide a pile having the above characteristics and in which no shell or container of any, kind is necessarily allowed to remain in the earth after the pile is completed.

A further object is to provide a simple and efficient method whereby to insure the formation of the lateral arms upon .the pile.

A further object is to provide a method in which the reinforcing elements for the lateral arms are themselves made use of in the formation of pockets within the earth, which pockets are adapted to receive the concrete material for the arms.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims. i

In the accompanyingdrawings which are to be taken as a part of this specification, and in which I have shown merely a preferred form .of embodiment of the inver;q tion;

Fig. l is a longitudinal sectional view illustrating the first step in the course of constructing a pile in accordance with this invention.

Figs. 2 and 3 are views similar to that shown in Fig. l, but illustrating successive further steps in the work of forming the pile.

Fig. 4: is a side elevational view of a completed pile.

Fig. 5 is a view similar to that shown in Fig. 4 but illustrating a modification, and

Fig. 6 is a top plan view of a modified form of the arm-forming and reinforcing element.

IVhile the drawings herein illustrate the pile former, or shell,4 as being of the nonsectional type, yet it will, of course, be understood that a sectional shell may be employed in many instances and that the objects of this invention may be attained equally well with either type of shell.

Referring to the drawings, and particu-V larly to the structure shown in Figs. 1 to 4, for describing in detail the features therein illustrated, the reference character L indicates a pile former or shell, and the reference character (i indicates a nose piece positioned at the lower end of the'shell for facilitating the driving ofthe shell into the earth.

After the shell L, with its nose piece G, has been driven into the earth, as indicated in Fig. 1, and before the pouring in of the concrete, the shell is lifted a slight distance, as indicated in Fig. 2. With the shell in this position one of the arm forming and reinforcing elements, as H, is lowered into the shell and into engagement with a guide plate 1 previously lowered. In some instances it may be desirable to place the guide plate and the former H within the shell before the shell is raised.

MA driving weight 2 is then lowered into the shell and is employed for drivlngthe former H downwardly and outwardly into the earth below the lower edge of the lifted shell. the former AH at` different periods occupying the successive. positions indicated by the dotted lines in Fig. 2.

The former H may be of any appropriate construction, its essential characteristics being simply that blows, or other appropriate operation thereupon will cause por* tions of the former to be forced outwardly into the surrounding earth, the operation Vterial of the preferably serving to scoop out pockets, as 3, within the earth communicating with the interior of the shell. Y

1n the instance illustrated, the former consists simply of two members, as 4 and 5, pivotally connected together, as atA6. -The rmembers 4 and 5 yare of U-shape cross section, each providing a top wall 7 having opposite side flanges 8 thereon. from the weight 2 are applied at the p ivot 6 and the lower ends of the members 4 and 5 are thus caused to slide or cam over the opposite edges of the guide plate 1, the top walls 7 of said members then serving to scoop out and press back the earthy material so that- `when the members 4 and 5 are inv their final positions, as seen in Fig. 3, they will constitute ro'of portions for the pockets 3 which have been formed by their movement. The flanges 8 serve to hold the top wallsI lifted away from the guide plate so as to form suitably proportioned passages 9. communi- -cating between the pockets 3 and the interior of the shell.

The former is allowed to remain in this position, the weight '2 is withdrawn and a quantity of concrete material of suitable consistency is introduced into the shell and is allowed to flow outwardly thru the passages 9 into the ockets 3 filling said pockets and passa-ges. /lore of the concrete material is thenl introduced. The lifting of the shell and the lpouringin of more concrete material may then progress until the pile is completed without introducing more of the formers H.v

The concrete material which has flowed into the pockets 3 forms the arms 10 and is integral with the concrete material of the main b-odyof the pile. The members 4 and 5 of the former H comprise portions of said arms and effectually reinforce the arms since they extend Jfrom connected relation within the body outwardly over the upper surfaces of the concrete material of the arms.

Wherever it is desired to provide more of the arms 10 this may be readily accomplished by\ simply introducing additional guide plates 1 and formers H at different levels as the filling in of the concrete maile progresses, as is clearly indicated by t e illustration Fig. 3. The operation in each instance will be thesame as has already been described for the lowern `concrete material 1n pile formation., an 1nmost arms.

In this way the piles, having a multi. plicity of arms, such as are illustrated in' Figs. 4 and 5, may be formed. The nose piece G is allowed to remain in the earth and serves as a` suitable founda' tion directly beneath the main body of the pile after the pile is completed.`

In the illustration Fig. 5 the construction land mode of operation for producing the r1he blows pile of this figure is substantially the same as has already been described except that inthis figure is illustrated a separate auxiliary shell, or container 11 for the concrete material, which auxiliary shell 1s allowed to remain in the earth after the main shell L isremoved. The shell v11 may be of thin sheetmetal, or it may be of any other appropriate material, such as paper or the. like, as indicated in my pending appllcation Serial No. 306,134, and it'may be introduced into position eitherl after the main shell Lis sunk into the earth or it may be i placed around the outer surface of the shell L and sunk into the earththerewith, as may be found most rappropriate and convenient.

Where the auxiliary shell 11 is present the formers H simply tear thru the material thereof in the process of forming pockets 3 for the arms 10i The presence of the auxiliary shell may be of importance in some cases, for instance, where the surrounding earth is of a soft or unstable character. In these cases the auxiliary shell will Aserve to maintain the mam body of thepile in proper pile formation during the setting period.

Also, where the auxiliary shell is closed at `its bottom end, or is otherwise waterproof,

as suggested-in .the co-pending application referred'to, said shell will serve to prevent the ingress of soft earth or of water thereinto during the sinking of the shell Ly into the earth and prior to the introduction of the formers H.

1n the Amodification Fig. 6 an arm-forming element is indicated which consists of four separate formers or reinforcing members 12 all pivotally connected to a single central member 13. This type of former may be employed in some instances where the earth is suitably soft and where it is desired to provide greater bearing surface upon the earth.

As many changes could be made in lthis construction, without departing from the scope of the following claims, it is intended that all matter'contained in the above description, or shown in the accompanying v -drawings, shall be interpreted as illustrative only and not in a limiting sense.

Having thus described my invention, what I. claim as new and desire to secure by Letters Patent is:

1. A concrete pile comprising a body of tegral arm of the concrete material projecting laterally from said body, and a reinforc-l ing member for said arm engaging the iio upper surface thereof and projecting into embedded relation within the body.

2. A concrete pile comprising a body of concrete material in'pile formation, a plurality .of integral arms of the concrete material projecting laterally from said opening, said former being intended to remain in position after the placing of the concrete and comprising parts adapted to extend between the pocket and the pileshaped opening so as to reinforce the connection between the concrete within said pocket and the concrete within said opening.

4. rIhe herein described method of forming'a concrete pile which consists in pro- `viding a. shell, sinking said shell into the earth, introducing a pocket forming element into the shell, lifting the shell for` a short distance, thereafter forcing said pocket forming element outwardly beneath the lower edge of the shell into the surrounding earth for forming a pocket in the earth communicating with the opening left by the lifting of the shell, and then filling said pocket with concrete material extending into the opening beneath the shell.

5. The herein described method of forming a concrete pile having a plurality of lateral arms formed thereon at Idifferent points iny the length of the pile, which consists in forming a pile-shaped opening within the earth, forming a pocket in the Wall of said opening, placing a quantity of concrete material within said opening to fill the pocket and to partly fill the opening, utilizing the topy portion of the concrete material Within the opening as an operating support by the aid of which to form another pocket linthe wall of said opening at a.v level above the first pocket, placing a second quantity of concrete material within said opening to lill the second pocket and to further lill the opening and thereafter continuing in accordance with the number of arms desired.

6. A concrete pile comp-rising a bodyof concrete material in pile formation, va plurality of pairs of arms of the. concrete material projecting laterally from said body, the arms of each pair being disposed to project from substantially diametrically opposite sides of the body, and a plurality of separately formed reinforcing elements one for each pair of arms, said reinforcing elements extending transversely thru the body and proj ectingl from opposite sides thereof into reinforcing relation with the respective arms. A

7. The herein described method of forming within the earth av concrete pile having a reinforced laterally extending integral concrete arm thereon which method consists of forming a pile-shaped opening Within the earth, introducing a former into said opening, operating said former to form a pocket within the earth inthe Wall of said opening, said operation leaving said former extending between said opening and said pocket,

and then 'filling said opening and said pocket with concrete material while said former remains to constitute reinforcing means for the arms.

In testimony whereof I aflix my signature in the presence of two Witnesses.

MAURICE BLUMENTHAL.
