SHEET-METAL FILING. 1 r

Specification of Letters Patent. Patented Mar, 14, 1916.

. Application filed August 22, 1914. Serial lt'o. 858,008.

To all whom it may concern:

Be it known that I, Gnonon D. MOULTON, a citizen of the United States, residing at Denison, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Sheet-Metal Piling, of which the following is a specification.

My invention relates to new and useful improvements in sheet metal piling, and its objects are, first, to provide a sheet metal piling of the lock joint type that will be positively proof against leakage at the joints, and second, to provide a sheet metal piling that will not require the production of a strong frictional engagement between adjacent piling members, thus making 1t possible to use a lesser force in driving or withdrawing the piling than is posslble when such strong frictional engagement is produced.

A still further object of the invent1on 1sto provide a device of the'character described, that will be strong, durable, simple and efiicient and comparatively inexpensive to produce, also one in which the several parts will not be likely to get out of working order.

l/Vith the above and other objects in view, the invention has relation to certain novel features of construction and use, an example of which is described in the following specification and illustrated in the accompanving drawings, wherein:

Figure 1 is a fragmentary view of a wall formed bv my improved sheet metal piling, said wall being shown formed with an angle. Fig. 2 is a plan view of a portion of the wall. Fig. 3 is a perspective view showing a portion of a wall formed by a slightly modified form of piling. Fig. 4 is a similar view of another modification. Fig. 5 is a section taken on aa of Fig. 4. Fig. 6 is a section on )b of Fig. 5.

Referring now more particularly to the drawings, wherein like reference characters designate similar parts in allthe figures, the numeral 1 denotes the sheet metal piling sections, each of which is integrally formed at its vertical edges with split sleeves as indicated at 2 and 3, the former being somewhat smaller in diameter than the latter. The sleeve 2 of each section 1 is adapted to fit snugly within the larger sleeve 3 of the adjacent section as is shown clearly 1n Figs. 1 and 2. Furthermore, a vertically elongated pointed tongue 1, which is formed integral with each section 1 and projects diametrically across the sleeve 3 thereof is adapted to project through the opening in the sleeve 2 that is introduced within said sleeve 3. The joints are formed as above described by driving each member 1 down with its sleeve 3 embracing the sleeve 2 of another member 1, the two members being in the same verti cal plane. Previous to being put into use, the opening of each sleeve 2 is filled with asphalt or some other bituminous compound, and the same is allowed to harden within the sleeve. When the piling thus treated is driven as has been already described, the tongues 4; will cut their way into the asphalt 5 contained within the sleeves 2, the contact between the asphalt and said tongues being so positive in its nature that no leakage can possibly occur at the joints.

In the modified construction illustrated in Fig. 3, the sleeves 3 are each formed in two parts separate from the sections 1, and are oppositely riveted to said sections at the.

pointed edges 4 thereof.

The construction shown in Fig. 4 differs from that shown in Fig. 3 in that the parts forming the sleeves 3 are provided onlvat the upper and lower extremities of the sheet metal sections, metal.

In each form of my invention, the lower ed es of the sections 1 will be sharpened as thus economizing in the indicated at 6 to facilitate driving, the lower extremities of the sleeves 2 being given cone shapes as lndicated at 7 (see Fig. 6) for the same purpose, and the lower edges of the sleeves 3 being beveled as indicated at 8 for r the same purpose.

The invention is presented as including all such modifications and changes as properly come within the scope of the following claims.

What I claim is:

1. A lock joint sheet metal piling comprising sections each having a split sleeve formed upon one of its vertical edges and having its other Vertical edge formed into a tongue with sharpened edge, the tongue of each section passing through and closing the opening in the sleeve of an adjacent section,

in combination with a filling of bituminous material in place in said sleeve.

2. A look joint sheet metal piling comprising sections each having a split sleeve formed upon one of its vertical edges and having its other vertical edge formed into a tongue with sharpened edge, the tongue of each section passing through and closing In testimony whereof I have signed my the opening in the sleeve of an adjacent secnameto'this specification in the presence of tlon, 1n combination with'a filling of bltumitwo SLIbSCIIblHg Witnesses.
