DANIEL E. MERRIOK, OF MILWAUKEE, WISCONSIN, ASSIGNOR OF O NE- HALF HIS RIGHT TO J. B. SMITH, OF SAME PLAGE.

IMPROVEMENT IN JOIN'I'S FOR IRON SHIPS AND TANKS.

Specification forming part of Letters Patent No. 142,406, dated September 2, 1873; application led May 8, 1873.

To all whom it may concern:

Be it known that I, DANIEL E. MEREICK, of Milwaukee, in the county of Milwaukee, in the State of Wisconsin, have invented certain Improvements in'Seams for Iron Ships, Tanks,

8vo., of which the following is a specification: My improvement relates to the joining of sheets of metal and making the seams tightfor the hulls of steamships, tanks, Ste., and is made by a piece of metal riveted over the edges of two sheets of iron or any other metal, with a central rise orV tongue coming up between the two sheets of metal, and this eentral piece riveted or headed down tight, and with seams or grooves in the lapping piece of metal, in which to put cement or any kind of y packing, so that the joint shall be tight and remain so permanently. l

Figure 1 is a plan view ot' my invention; and Fig. 2 is a sectional view, showing the ends of the sheets of metal, and the tongue between the two riveted down, and the ends ofthe grooves. Y

A, the sheets of metal fastened together;

-B, the lap 'pieceof metal 5 (l, the rivets; D,

the tongue rising ,up between the sheets of metal, riveted' or headed down even with the surface; E, the grooves for packing. The

piece of metal, with a rise in it forming aeted down smooth, makinga solid, tight joint- 011e as solid and strong as the metal is at any other place, and perfectly smooth on the outside of the vessel, as the holes for the rivets in the sheets of metal A are eountersunk, and the rivets are calculated. to just rivet down even with the surface of the sheet.

For a tank, the piece of metal B may be made without the tongue D, and then fill the grooves E with cement and rivet down solid. The piece of metal B is put on the outside and calked, making the inside smooth. i;

I claim as my inventionl. A seam or joint of metal made with a strip of metal, B, with a raised tongue, D, in in its center riveted to sheets A, and tongue D headed down even with sheets A, and the heads of the rivets countersunk on the smooth side of sheets A, substantially as described.

2. A seam of metal when made with sheets A, strips B, rivets O, and grooves E, all combined substantially as described.

3. A seam or joint of metal when made with sheets A and strips B, one of the strips B runev ning lengthwise of the sheets A, and the other strip B running erosswise of the ends of sheets A, with tongue D headed down even with the surface of sheets A, the strip B running across the ends of sheets A being let into the side of the other strip B, so that its end shall strike tongue D,and both strips B riveted to sheets A, substantially-as described.
