art union NiTEn STATES PATENT oF-F oE- JULIUS WEMLINGER, or FIEFTKLYN, NEW YORK. METAL SHEET-FILING.
Patented March 26, 1907.
Application filed October 6, 1906. Serial No. 281,674..
To all whom itmwy concern: Beit known that LJuLms R. WEMLINGER, a citizen of the United States, residing at Brooklyn, in the county of'Kings and State of New York, have invented certain new and useful Im rovements in Metal Sheet-Piling, of which t e following is a specification.
In the design of a unit for metal sheet-piling a very important, if not the most 1m portant, requisite is stiffness, because the umt mustbe so rigid that it may be driven through any ordinary material without buckllng. This stifiness must be obtained with out making the section unusually heavy; otherwise the cost of the material and that of ts handling is prohibitive. Furthermore, it is important that all the units besuch as ma be easily manufactured and fabricated with the least possible number of parts, and it is advantageous to have all the units alike and interchangeable.
The structural shapes'which have been and are used to agreat extent in metal sheet-pilmg may have certain advantages; but these are more than offset by the ineffectiveness of said sha es for the work required of them and the 'gher cost due to excessive weight. These structural shapes are designed for an entirely different purpose from that of sheetpiling. For instance, a rolled channel, while very eflicient'and particularly designed to resist forces applied to it in a direction parallel to its web, is weak and ineflicient. when subject to forces applied to it in a direction pe endicular to its web, as will be readily un erstood' by those familiar with the design of structures. Therefore in order to provide astrong and economical unit it is advisable and preferable todesign a special section and one whose configuration is such that the wall of piling shall be as nearly as possible of uniform thickness. In cases. where the piling is made up of units of diiferent'configuration and weight the strength of the wall of piling is of course limited to. that of the weakest member,and it-follows that in such a case there must bean excess of weight at the joints and in the heavier members.
I have found, by means ofwell-known calculations, that in trough .shapes, such as shown in my application Serial No. 240,987 and in the resent application, the bending moment wit respect to the neutral axis. parallel to the web is more-than one hundred and fifty per cent. "greater than the corresponding bending moment of a3. rolled channel and' wide and of the same depth as the channel are useful beyon of the same unit weight as at the expense of width of section, because in actual dimensions the trough-sections investigated are one and one-half (1%) times as and nearly twice as wide and shallower than the flange width of the I-beam referred to. These trough shapes are therefore 'very rigid in driving and by reason of their arched section are well adapted to withstand the thrust of the material behind them. Furthermore,
they are extremely easy to manufacture and Y can be rolled to their final shape as easily as anfi other standard structural shape.
eferring now to the annexed drawing, which forms part'of this specification and in which like numerals refer to like arts, Figure 1 is a transverse section throng a plura ity of units joined together. Fig. 2 is a section similar to that of Fig. 1. Fig. 3 is a section of a comer-piece adapted to be used in connection with the units shown in Fig. 2.
Each unit of the sheet-piling is composed of a web 1, sides 2, and locking edges 3, which may be formed of a bulb or rib, as shown in Fig. 1, or a thick flange, as shown in Fig. 2, or any other marginal-enlargement which will answer the purpose sought to be obtained.
The web 1 is arrange with a locking member 4, secured to the .Web by rivets 11 and having upturnededges 5, which form aspace 6 for receiving and locking the edges 3 o the contiguous units'as the piling is driven in the usual way. In this manner a very strong and efiective joint between the separate units is obtained, while the locking edges 3 also serve to reinforce the ed es 'of the members 2.
The great strength'o all the units allows the use of much thinner metal than is required for other shapes. Furthermore, the locking edges 3, by reason of their comparative bulk, serve a valuable purpose in the rolling of these sections. It is well known that in rollin trough-shaped sections of thin metal it isdi cult to keep the sides straight, because there is not enough material present vto give the edges stiffness in their heated 's reason the thick edges 3 state, and for t their serving to lock the units together. v
In Fig. 3 I have shown a'corner-section, which may be used at the intersection of two nearl seventy per centfgreater than that of "an I- earn, bot
the trough shape under consideration. Moreover, thisremarkable excess of strength over to the structural shapes naniedis not. obtained lines of the sheetpiling. This corner-section i is composed of members 7, which may be part of the main sections of the piling, strips 8, and a corner-piece 9, all secured together by rivets 10, so that the whole can be driven in a man 5 nor similar to that used in driving the main units.
In the drawing I have shown units having I diverging or inclined sides 2; but these may of course be made substantially parallel, if advantageous or preferred.
What I claim as new, and desire to secure 2 by Letters Patent, is
1. In metal sheet-piling, the combination 3 of units having a web and sides, said sides having enlarged edges, means secured to said 1 web for joining the said units together. l
2. In metal sheet-piling, the combination I of trough-shaped units, each having a web I and sides, said sides having marginal enlargem'ents, splices secured to said web for joining l thesaid units.
3. In metal sheet-piling, units each having i a flat web and sides, said sides being arranged with a marginal enlargement, means secured to said web for receiving'and securing portion of the contiguous units. 4. In metal sheet-piling, the combination of units each having a fiat web and sides, said i sides being arranged with marginal enlargel ments, splices secured to said web adapted 3 to lock the said units together.
5. In metal sheet-piling, the combination of units each having a flat web and sides, said I sides having thick edges, splices secured to said web adapted to overlap and lock the said ed es. 1
In metal sheet-piling, units each having aweb and sides, said sides having thick edges, 1
5 mg I that the sides 0 splices secured to the webs of said units and formed of strips having locking-flanges.
7. In metal sheet-piling, units of trough shape each having a Web and flaring sides,
said sides having marginal enlargements,
splices secured to said units and formed of strips having locking edges which overlap the said marginal enlargements.
8. In metal sheet-piling, the combination of trough-shaped units, each having thick 5 edges and arranged so that the sides of con tiguous units overlap each other over their entire widths.
9. In metal sheet-piling, the combination of trough-shaped units having ribbed edges and arranged so that the sides of contiguous units overlap each other.
10. In metal sheet-piling, units each having a web and diverging sides, said sides havmarginal'enlargements and arranged so f contiguous units overlap each other over their entire widths, splices secured to said units for locking the same toi gether.
11. In metal sheet-piling, the combination of units each having a web and diverging sides, said sides having marginal enlargements and arranged so that the sides of contiguous units overlap over their entire widths,
I locking-pieces secured to the said units and each formed of a strip having edges which overlap the said marginal enlargements.
In testimony whereof I aflix my signature in presence of two witnesses.
