LUTHER RFRIESTEIDT, OF CHICAGO, ILLINOIS. SHEET-PILING. SPECIFICATION forming part of Letters Patent No. 735,489, dated August 4, 1903. Application led May 21, 1903. Serial No. 158,111. (No model.) V TotZZ whom, it may concern: Be it known that I, LUTHER P. FRIESTEDT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sheet-Filing; and I do here-AA either a permanent or temporary character. ,ication The beam-sections A are provided with rib r bar edges, the web of the beams bisecting the same so, that the thickened part Will be raised equally on each side thereof. The ribs 4:, formed ou the respective edges of sections A, are approximately square in cross-section and provide a locking-shoulder 5 on each side. v The alternately-joining beam-sections B are provided on eac-hedge with an integral jaw 6, formed with a groove or recess? of a shape to fit over one side of the ribs 4, the` hook edge of the jaw 6 having a locking en` gagement with the shoulder 5 on that side of the beam-section. A companion jaw 8 is 1ocated on the opposite side of the beam in forminga double-jaw connection. The jaw members 8 are separate parts and are provided with a riveting-Bange 9, through which the rivets IOQare inserted in rigidly securing the same to the beam-sections B. The hook edge ll of the jaw members 8 engage the shoulders 5 on the side of the Wall opposite to that of the jaw members 6 in forming a complete interlocking engagement of the beam-sections. It will be understood that the interlocking rib and jaw edges run the full length of the beam-sections and also provide the usual guide features when assembling the beams in the operation of driving. In the modification, Fig. 3, the rib edges a of the sections A are cylindrical in cross-section and the engaging jaw edges b on sections- B of a corresponding contour to properly lit the same in assembling the sections. Having thus described` my invention, what I claim, and desire to secure by Letters Patent, is- l. In metal sheet-piling, a beam-section provided with thickened rib edges,and a joining beam-section provided` with jaw members along the respective edges thereof and adapted to engage said rib edges in locking the sections together as they are assembled in a wall structure, substantially as set forth. 2. In metal sheet -piling, a beam -section having ribs formed on the respective edges thereof that are bisected by the web part and a joining beam-section provided with jaw members extending around on each side of said ribs in an interlocking engagement, sub-` stantially as set forth. 3. In metal sheetpiling, a beam -section provided with ribs on its respective edges that are bisected by the Web part and have shoulders formed along the inner sides thereof, and a joining beam-section provided with fixed jaw members having hook edges en# gaging said shoulders in locking the beamsections together, substantially as set forth. In testimony whereof I aifix my signature in presence of two Witnesses. LUTHER P. FRIESTEDT. Witnesses: J. B. DoNALsoN, L. B. COUPLAND.
