METHOD OF MAKING FILES.
Application filed April 20, 1925. Serial No. 24,398.
This invention relates to the building of walls of iron piles. For the production of walls of this kind a great variety of types of rolled piles of various cross sections have been proposed, all of which however have serious disadvantages. Piles with a sickleshaped or S-shaped cross section are also known. Piles with a double-curved 0125- shaped cross section are diflicult to roll. Piles with a single curved or sickle-shaped cross section frequently do not offer sutfi cient resistance to lateral bending stresses and are particularly difficult to ram in large lengths, this being largely due to the tendency of a pile that is being driven to pull an adjacent pile down with it.
The object of the present invention is to produce a pile which can be easily rolled like a pile with a sickle-shaped cross section but which at the same time oifersgreater resistance to lateral bending stresses. Furthermore, a pile constructed according to the present invention, can be rammed in as readily as one having an S-shaped cross section. This is accomplished by making the piles of twoparts of sickle-shaped cross section and joining these parts together so as to form an S-shaped pile before it is rammed in. The two sickle-shaped pile elements are formed at their edges with interlocking members that are caused to interlock by the application of lateral forces. It has been found that bi-part' piles produced in this manner have excellent ramming proper ties. Thus piles having'a full-wave cross section have two properties which render them superior to those which are provided with a half-wave cross-section. In the first place, the former has double the inertia of I p the locality where the pile wall is to be built the latter. In the second place the resistance offered by the medium in which the piles are. driven, is doubled for the former as compared to the latter while the sliding friction between a previously-driven pileand one in process of being driven, is substantially the same for piles of both types. It is in connection with these properties that the advantages to be derivedby the hereinafter described method of making piles with cross-sections of compound curvature, will be apparent, I have found that a very advantageous form of bi-part pile is produced by providing the interlocking edges of'the parts with projections or'protuberances which assist the frictional forces at the joint in preventing the parts of the bi- .erosswise, may be produced.

part pile from being displaced relatively to each other during the ramming operation.
The invention is illustrated by Way of example in the drawing in which- Fig. 1 is a cross section of a sickle-shaped pile element,
Fig. 2 is a section through a bi-part pile with an S-crossv section formed by joining two pile elements of sickle-shaped cross section together.
Fig. 3 is a side view of a bi-part pile viewed in the direction of the arrow of Fig. 2.
Fig. 4 is a fragmentary transverse section through the longitudinal joint between the pile sections.
Fig. 5 is a longitudinal section of the same corresponding to the line AB of Fig. 4.
The pile elements for producing walls of iron piles according to my invention consist of beams a, Fig. 1, of sickle-shaped cross section which may be provided at one edge with a protuberant part or rib b and may be formed at the other edge in the form of a trough or claw c. When the iron elements or beams, Fig. 1, are rolled, lateral protu-.
berances b and projections (Z that extend These protuberances .or projections must be shaped so that they allow the claw c of the second part of the pile to be slipped over them. When the claw of a second part has been slipped over the edge of the first part provided with protuberances or ribs 6, lateral forces as indicated by the arrows in Fig. 2 are applied to the checks of the claw 0 so that the claw 0 firmly interlocks with rib b at the edge of the second part. This interconnecting operation can be carried out at or it can be executed at the rolling mill by means of air-drivenha'mmers. The edge 6' is thereby made to grip the lateral rib 7) and also the transverse projections cl so that the two pile elements are fixed to each other not only by the friction between their interlocking members but also by a positive inter- The projecting locking ribs a? and co-o'perat-ing recesses 03 in the claw 0 may be produced when rolling the pile elements by simple means well known in the -art.

of the invention. The important featureconsists in forming a ile with 'across section of two slm'ilar e ements a whlch are joined together before ramming. In conviously rammed pile. This will depend parts and with the curved cross-sections of on the position of the pile wall.
It has been found in practice that by the. afore described method very long piles can be easily rammed without any of the difliculties arising that have been encountered in driv-- ing piles with known cross sections. The novelmethod is particularly adapted to overcome the danger of deflections of the "piles or of their interlocking members parting from each other. -As has been pointed out'above, this method affords a practicable way to make and use piles with a full-wave cross-section in place of those which have a half wave cross-section. It therefore becomes feasible to overcome the objections which are inseparably connected with the use of piles of the latter type. To be particularly noted in this connection is the possibility of greatly reducing or. practically eliminating the tendency 0n the part of a pile in process of being driven to drag down a previously-driven pile with which it is in slidable contact along one edge. This is 'so for the reason-that a pile with a fullwave cross-section has double the inertia and doublethe resistance to overcome during the pile-driving operation as compared with the same factors connected with driving a pile which has a half-wave cross-section. Thus, inertia and driving reslstance are'doubled in the former as compared to the latter while the frictional engagement plementary parts of said pile with oppositely curved half wave cross-sections, and in rigidly uniting said parts along ad oining longitudinal edges thereof with the halfwave cross-sectioned parts extending in opposite directions from the rigid joint between-the adjoining edges of said complementary parts.
