TAPEBED FILING y Gerald G. Greullch, Mount Lebanon, Pa. Application December 29, 1937, Serial No. 182,355 1 Claim. (Cl. 81-53) 'Ihe present invention relates to metallic piling and, more particularly, to a metallic shell for casting concrete piles.
An object of the present invention is to provide a tapered metallic piling shell with integral projecting stiftening ribs increasing in width as the diameter of the pile section decreases.v
A further object is to possessing sufficient strength to withstand the impact forces imparted thereto during the driving of the pile into position.
Other objects and advantages will become ap-` roceeds. in which: elevation of the presof relatively short lengths welded together;
Figure 6 is a top plan of Figure 5 showing the reenforcing ribs; and
Figure 7 is a modied form of the manner of welding the segmental sections together.
In the drawing, the numeral 2 designates the preformed complementary metallic sections forming the piling shell. These complementary sections may be made of rectangular stock and preformed to the desired cross-sectional shape with iianges 3 extending laterally from said sections. 'I'he anges 3 increase in width as the conical portion of the pile decreases due to the taper produced during the forming operation, which may be any standard practice, for example, a press having interchangeable dies so that a uniform degree of taper may be produced in the complementary' sections forming the assembled piling shell. These ilanges provide reenforcing ribs throughout the longitudinal length of said piling shell and, due to their increasing width. sulcient rigidity is supplied to said pile during the driving operatio to permit the piling shell to resist lateral forcsf which might tend to force the shell out of it"line of travel through the ground strata. However, it desired, the complementary sections may be so formed as to eliminate the lateral iianges and, under such a construction the edges,` of the complementary sections'may be overlapped and welded, in any cons ventlonal manner. as shown in Figure '7.
provide a tapered pile unitary piling shell of as the diameter of said understood that I do The piling shell may be made up from a number of preformed like segmental sections, as shown in Figures 2 through 4, which, when welded at their respective flanges, will provide a unitary complementary section adapted to abut o and be welded at their another preformed section abutting edges.
The piling shell may be produced as shown in Figure 5 by providing preformed standardized lengths of sections 5, 6, 1, 8, 9 and I0 of varying- 10' diameters and degrees of taper so that when each preformed section is positioned and arranged for welding 'to the next section, there is produced a desired length and taper. Under this form of construction, each segmental4 section is provided with longitudinally disposed reeni'orcing ribs I2 which, togethery with the welded flanges I4, provide suilicient reenforcement for the light gage stock to withstand the force transmitted to said driving operation,
Secured to the penetrating end of the assembled shell, by welding or otherwise, is a piercing point l5 having an annular fiange'IB extending within and engaging the inner wall 25 of the unitary section 2. Y
The piling shell of the present invention is preferably formed from relatively light gage stock, and it is therefore necessary that the end be rprotected during the driving operation to 30 position the shell in the ground prior to the pouring of concrete. A protective ring I1 is positioned within the driving end of said piling shell, saidrlng having a iiange i8 extending outwardly to a point substantially edges ot the iianges 3.
The number of segmental units desired to i'orm the piling shell are positioned in superimposed relationship and welded into a unitary assembly so as to produce, in one case, a tapered piling shell having ilanges or ribs increasing in width piling shell decreases and, in another case, a plurality of preformed sections of varying diameter and degrees of taper which,
when welded together, produce a unitary tapered 45 structure having ribs ot uniform width throughout the tapered assembly.
Instead of providing the segmental sections with uniform or increasing width anges, these segmental sections may, if desired, have their 50 edges overlapped and welded, as shown in Figure 7. l
While I have shown bodiments of the present invention, it will be not wish to be limited explling shell during the 20 coincident with the outer 35 and described specific emactly thereto, since various modiilcations may be made without departing from the scope of the invention, as defined by the following claim.
I claim:
A tubular metallic pile she comprising a phrrality of complementary arcuate sections welded Atogether to provide a hollow chamber whose interior 'diameter gradually decreases toward its bottom portion, a. piercing point welded to the o bottom portion of said hollow chamber, integral reenforcing ribs on said arcuate sections increasing in width as the diameter of the piling shell GERALD G. GRJIHIL'ICH.
