METALLIC SHEET-PILING.

Specification of Letters Patent.

Patenten Jan. a, 1916.

Application led October 1, 1912. Serial No. 723,306.

.T0 all whom it may concern Be it known thatI, J ULIUS R. WEMLINGER, va citizen of the United States, residing in the city of Brooklyn, and State of New York, have invented certain new and useful improvements inlMetallic Sheet-Filing; and I do hereby' declare the following to be a full, clear, andexact description of the invention, such as Will enable others skilled in the artto Which it appertains to make and use the same.

My) invention relates to certain improvements in metallic sheet piling with particular reference to the arrangement and construction of interlocking atl the adjoining One of the objects of my invention .isl to provide a metal sheet pilingVthe respective pieces or sections of which may be locked togetherby lateral movement; instead of.,

ofthe edge of onepiece -into the end of the edge of the other piece various close any .given space. I tive v1evv showing, 1n

swinging it into space `view .of 'another 'edges ofv which are corrugated or curved, as

and then moving or driving the enteringl piece' longitudinally as customary with vother forms of interlocking sheet piling.

My invention also resides in certain and details of construction to accomplish the purposes desired, as will hereinafter appear. v

Referring now to the accompanying sheet of-drawings which forms a part of this specification z-rFigure 1 is a 'plan view of one piece vor section of my improved metal is a plan view of a numgether, the two .upper sections being in straight alinement, and those at the.left, hand side of the view being assembled at diiferent angles of alinement,l showing the adaptability of my construction to various forms or outlines, as ma)l be desired to in- Fig. 3 is a perspecfull lines, two of the improved sheet piling in place in a vertical position and in this view the dotted lines indicate the preliminary position of the left-hand section prior to sections of my final position' as shown by full lines. Fig.' 4: isa .plan view of a corner section of my: improved piling which is adapted to make a right vangle connection. Fig'. 5 is a plan form of my piling, the

in the county of Kings proportionally thinner,

shown, to form joints in the same manner as those of the fully corrugated sections. This style embodies my lateral joint construction, gations. Fig. 6 is a front elevation of my metallic sheet piling, the clip'. members of which are made in separate pieces secured at intervals to lthe main vbody of the piling section and alined longitudinally thereon, as shown, this construction being especially well adapted for lateral joining as described herein. Fig. -7 is a plan View struction shown in Fig. 6.

but Without 'the intermediate, corru- Referring now to the single piece of sheet piling illustrated in plan 1n Fig. composed of a corrugated metal plate which, in cross section or plan as -shoWn,is formed with a curved end ar'c 1, the adjoining curved arc 2, the intermediate arcs, the

other end arc 5 and its adjoining arc 4.'

These arcs are of circular form, either segmental or semi-circular, as shown, the intermediate ones being joined by straight portions or tangents 6. The inner radius of the arc l is made substantially the same as the exterior radius of the arc 5, so that When the pieces are joined together they Will it closely, stantially tight to hold earth, sand or'other materials, either dry or Wet.

The thickness of the sheet piling as shown on the drawings is somewhat exaggerated, as compared with the other dimensions, for the sake of clearness of illustration, and I wish it understood. that these sheets may be or of any thickness that may be commercially or practically desired. I

1 :.-this is as indicated in Fig. 2,' and be sub- In order to practically produce my sheet piling, I prefer to press the same, as under to the finished cross j I ous or adjoining semi-circular arcs'throughout, such as 1 and 2, that there is' a greater 'I amount of resistance to be overcome than joined by tan?" if the intermediate arcs are gents or straight portions such as arranged at anglesof approximately sixty degrees, more or less. This matter of the ease of pressing the-form shownin Figs. 41 and 2,

joining, the edges of the section, as shown,

inorder to allow a certain amount of 'angular change in the line. of sheet piling. .without breaking the.- continuity of the' joints, as may7 be seen on 4reference to Fig. 2'. lf the marginal arcs l and 5 were not vsubstantially semi-circular or circular segments, the interlocking edges would not fit 'closely when the sections are assembled at an angle, whereas with the cross v section composed of circular arcs `near the edges,l

the joint between the sections remains tight during a considerable angular movement during which lthe margin of one sheet is held under the tongue 10 of the clip 7 as shown in Fig; 2. It should therefore be noted that a considerable amount of angular deflection is possible without separating the locked edges ofl the adjoining sheets, v`and meanwhile the joint remains tight. In

order to lock the adjoining sheets together,`

each unit or section is provided with a longitudinal Strip. or clip 7 riveted or otherwise securedalong the arc or corrugation 2, but at a considerable distance fromthe eXtreme edge thereof. If the clip 7 is riveted, l prefer to use flat headed rivets such as 13, as these offer less resistance to driving and pulling. The clip 7 is formed as l `shown with a portion 8. adapted to lit the curve 2 of the pile and is also provided with a shoulder 9 fitting closely to the piling section, and has a curved tongue l0 ending in an outwardly curvedlip l-l. thus seen to be composed of a curved tongue comprising the outer portion of the circular are 5, which fits in the groove, or space 15 between the tongue l0 and the corresponding circlilar arc l of larger radius than the arc- 5. This, therefore. forms a curved tongue and groove joint, whereby the adjdining pile sections may be connected by laterally placing the edge of one against the :edge of the other and then swinging or roy tating the free portion around the junction,

thereby locking the joint. This joint will hold` firmly against all usualpressures, although in certain cases where desired, waling strips and braces may be used temporarily to hold the line of piling in position.

The clip 7 is preferablvformed of a metal section rolled longitudinallyto the' shape' shown, but if more convenient or economical, it may be formed of ,a plate pressed closely to the Same shape, except that in this case, the shoulder 9 will not have such a sharp corner as shown in the drawings. This latter, however, is not a serious objection, if

The joint is lextra time and labor which igeasea there is no void or angular opening between the clip 7 and the corrugation 2 of' the steel pile into which the free edge of the adjoining. sheet pile might wedge itself in the process of placing or in use. j i

'The construction shown in Figs, 6 and 7 is similar to that illustrated in Figs-l, 2 and '3, with the single exception that the clips 7 andtheir integral portions 8, slioulders 9, curved tongues-l0 and upwardly curved lips ll are made in shorter pieces or sections, as shown. andl secured at intervals in longitudinal alinement by means of the rivets 13. Y

As shown clearly in Fig. 2 the tongue l0 of' the clip attached to one sheet pile projects ove'r the circular edge of the next sheet pile, thus locking the two together when in place. The tongue l0 Ais curved and sov formed that there is, an ample `clearance space l5 between the same andthe adjoining surface of the pile to whichit is attached, so that any irregularities in this or the adjoining Vsheets will`not cause trouble or delay. The. open space around the interlocking edges may be filledwith pacln'ng material, if desired,but this is ordinarily unnecessary.

Referring now to Fig. 3, it Will-Abe seen that the arrangement of circular segmental corrugations and the locking clip hereinbefore described, makes it possible to assemble the sheets together laterally by inserting the edge of one sheet under thetongue l0 ofthe locking clip 7 of the adjoining sheet when these are in angular relation with each other, after which the sheet is swung. j to the required angle or alinement, as shown assembling them in this way, theymay, of

,a novel feature of my invention, as in all other forms of interlocking sheet piling, it is only possible to assemble the adjoining sheets by sliding them together lengthwise.

While under certain conditions it is possible` to join sheets endwi'sevhenthe head room' and the hoisting apparatus are. both sufliicient to permit this, still it requires are obviated by means of my invention. v c My improved sheet piling is particularly applicable in cases where a construction of sheet piles for coiferdams, caissons or simi- .lar structures is assembled above the ground in order to make a closure to complete the l'is same before any of the piles are driven.A In. such cases, my piles can be joined together laterally Without lifting each section 'above' each adjoining section, which reduces the handling, labor, plant, timel and expense. If the piles aie of suchv a construction that they have to be joined endvvise, each section -must then be lifted above each adjoining one and slid endwise into place and this Will occasion a Waste of power and require ing apparatus almost twice as high, While the expense and time would be very much greater than with my lateral joint construction. In addition to this, in confined situations and Without overhead clearances, it isv impossible to place interlocking steel piling Whichis joined endwise, because a clearance twice the length of the longest pile must be provided, whereas with my improved construction it is possible to Work Within a space only very little higher thanthe maximum length of the piling.

' Fig. 4 indicates a plan or cross sectional view of a sty-le of corner piece adapted to form a right angle corner, this being coniposed of two corrugated sections having parallel-projecting edges 12 which are se-Q cured together by flat headed rivets 14, the outstanding curved portion 1 being provided Witli a locking strip 7 and the other outstanding portion 5 being substantially semi-circular and adapted to engage with the adjoining section as indicated. In this view the corner piece is shown in full lines, While the adjoining sections are shown in dotted lines, to clearly' show their respective positions when assembled.

Although I have shown my sheet piling as composed of corrugated sectionsVI do not Wish to be limited to this construction, as it is equally applicable to other forms, provided the lateral positioning and locking feature is` maintained.

Although I have shown and described my improvements in considerable detail, I do not Wish to be limited to -the `exact and specific details shown and described, but may use such substitutions, modifications or equivalents thereof, as are embraced Within the scope of my invention, or as pointed out Vin the claims.

Having thus described my invention, What l I claim and desire to secure by Letters PatsA ent is 1. A sheet pile formed of a metallic plate having edge.co'rrugations of substantially. and intermediate corrugations composed of segmental curvesv semi-circular cross section,
