lo constructing a wall having great strength andv rigidity. This and other objects and advantages of the invention will be more fully set forth in the following description made in connection with the accompanying drawing, in which like reference characters refer to similar parts throughout the several views, and in which Fig. 1 is a top plan view ofone form of my tubular piling;
Fig. 2 is a top plan view of a second form of my tubular piling;
Fig. 3 is a partial vertical view of a wall made of units such as shown-in Figs. 1 and 2;
Fig. 4 is a top plan view of-a third form; Fig. 5 is a top plan of a fourth form;
Fig. 6 is a top plan view of a corner forming unit for use with units such as that shown in Fig. 1, and v Fig. 'l is atop plan view of a fifth form of my pile unit. v
Referring to the drawing, the .form of my tubular piling shown in Figs. 1 and 3 consists of an elongated member 6 of circular tubular cross section having a pair of interlocking elements 1 35 extending longitudinally thereof and secured to diametricaliy opposite sides thereof. Each interlocking element l has a pair of mounting anges 'la formed integrally therewith and secured to the tubular member 6 by suitable means 40 such as welding or the-rivets 6. The two pieces each comprising an interlocking element 'I and a pair ofmounting flanges 1a are similar and are secured to the tubular member 6 with respectively opposite ends up.
The form of my pile shown in Fig. 2 is similar to the form shown in Fig.l 1 with the exceptions that the tubular member 9 is of generally oval cross section and the interlocking elements I0 are situated at positions corresponding to the ends of the longest diameter of the member 9. are
formed integrally with, welded to or otherwise secured to the member Sand are disposed with respectively the same ends up.l In driving this form of pile to form .a wall all of the pile units I6 are driven with the same end up.
(ci. si-ss). f
The form of my pileI shown in Fig. 4 is similar to the formshown in Fig. 3 with the exception that the interlocking elements il are situated in positions corresponding to the ends of the shortest diameter of the tubularmember i2. 5 The form of my piling illustrated in Fig. 5 consists of an elongated tubular member i3 of generally circular cross section but having portions o`f the wall thereof at diametrically opposite points bent inwardly to form a pair of dia- 10 metrically located generallyrectangular grooves or recessesl extending longitudinally of the member I3. An interlocking element i4 extends longitudinally of each recess and is secured to the por'- tion of the tubular element i3 forming the botl5 tom of the recess by suitable means such as weldi'ng or being formed integrally therewith. The two interlocking unitsiLof each pile are at,- tached to the tubular element i 3 with corresponding ends up. The depths of the recesses are so 20 dimensioned that facing portions ofadjoining piles in a wall formed4v thereof will abut each other, as shown, when interlocking elements I4 of these adjoining piles are placed in interlocking f .-relation. Thus a wan formed of such piles wm g5 have corrugated sides and Ithe interlocking elements il will be enclosed except at their ends..
To provide for producing corners or angles in a wall formed of the pile units illustrated in Fig 5,
anv elongated tubular member I5, formed in the 30 same manner as the member i3 and being provided with interlocking elements Il in the sameway, is used. However, the interlocking elements Il of the tubular member i5 are spaced apart circumferentially of the member I5 by' an angle 35 of `ill) degrees. as shown, or any other desired angle instead ofbeing diametrically opposite each other.
Fig. 6 shows a pile unit which is similar to the unit shown in Fig. 1except that the inter- 40 locking elements .I6 thereof are welded to or formed integrally with the tubular member I1 thereof instead of having a base riveted to the tubular member. Fig. 6 also shows a pile unit for use in forming corners or .angles in a wall 45 builtof the above described units of Fig. 6. The corner-forming unit is constructed in the same manner as the other units with the exception that the interlocking elements I8 .thereof are spaced apart circumferentially of the tubular 5o member i9 thereof by an angle of 90 degrees, asshown,.or any other desired angle instead of being diametrically opposite each other.
Fig. 7 shows a form of my piling identical with the' form shown in Fig. 6 except that the tubular 55 PATENT *o1-Elea anlass respective single interlocking elements II and Il of the respective tubular members i1 and i! of Fig. 6.
If desired the interiors of the tubular members of any of the above described forms of my piling may be filled with filling material 23 such as concrete, earth, sawdust, cinders or other material as indicated in Pigs. 1, 2, 5. 8, and 7. The recesses or grooves in which the interlocking elements of the form. of Fig. 5 are disposed may be filled with iilling material Il as indicated in Fig. 5. Filling with material. 28. as of course increases the strength of a wall made of my pile units.
In` all of the above described` forms of my piling, great strength is obtained throughthe use of tubular construetionin the same. Walk made from a plurality of my piling units are driven in the same manner as ordinary steel sheet piling but provide substantially a double wall.
It is apparent that I have invented novel and improved steel piling having a tubular form giving the same great rigidity and strength.
It will, of course, be understood that various changes may be made in the form, detaik, arrangement and proportions oi' the parts, without departing from the scope of my invention. which. generally stated. consists in a device capable of carrying out the objects above set forth and in the novel parts and combinations of parts disclosed and deiined in the appended claims.
What is claimed is:-
1. A tubular pile unit comprising an elongated tubular member, a portion of one side of Y said tubular member being displaced inwardly to form a groove extending longitudinally of said member, an interlocking element attached to said tubular membery and projecting therefrom and disposedatleastinpartinsaidgrooveaoda ysecond interlocking element attached to said tusubstantially in abutment with each other and said interlocking elements will be concealed 2. A tubular pileunit comprising an elongated tubular member having a pair of continuous circumferentiaily spaced radially disposed longitudinal .grooves therein, interlocking elements attached to said tubular member and projecting therefrom radially into said grooves, the interlocking elements oi the tubular member beim so arranged that when two such members are connected, one interlocking element of one member will engage with one interlocking element of the other member to bring the facing sida o! the two tubular members into contact adjacent the grooves wherein the engaging interlocking elements extend thereby concealing the enum interlocking elements and producing a multiple sealed joint between the adjacent members.
