A TTORNEYS.

Patented Oct. 4, 1932 CARL T. CABLSON, F ERIE, PENNSYLVANIA, ASSIGNOR TO ERIE CITY IRON WORKS OF ERIE, PENNSYLVANIA, A CORPORATION OF ZEEINNSYLVANIA BOILER Application filed February 5, 1931.

In the forming of steam boilers it is desirable in some constructions to arrange the tubes in a plane joining the axes of drums of the boiler. Where this is attempted difiiculty is experienced in assembling the tubes both initially and in the servicing of the boiler. The present invention is designed to form the tubes in a manner that-permits of easy assembling and still permits the tubes to remain in substantially the plane of the and lower drums, 4: tubes joining the rear drum and the lower drum, 5 upper water and steam tubes oining the front and rear drums, these steam tubes leading from the rear drum and front drum, 7 a steam chamber, and 7a a discharge nipple. A bank of tubes 8 connects the front and rear drums, this bank of tubes being preferably in a plane joining the axes of the drums. In the present invention these tubes are oil-set intermediate their ends at 9, the off-setting preferably equalling the spacing of the tubes in the several banks so that the tube enters an opening 10 in the front drum and an opening 11 in the rear drum off-set one space.

In assembling the tubes 8 one end of the tube is swung down. This gives sufficient clearance to permit the entry of the entering end and after the entry of the entering end the tube can be swung up to the horizontal and assembled in its opening without difficulty. The tubes thus arranged present no pockets so that there is perfect drainage where the boiler is let down. It is Very desirable to have the tubes at this position in that these tubes approximate ordinarily the water Serial No. 518,538.

level and the surging of the boiler carries the level in the front drum slightly above that of the rear drum and the direction of delivery to the rear drum is such that the water and steam carried across readily separates and the tubes below this position with the up-turned ends give some difiiculty in this respect and in respect to drainage. Therefore, the tubes along this plane are very desirable.

What I claim as new is 1. In a boiler, the combination of two drums having their axes in approximately the same plane; and tubes connecting the drums in approximately said plane, said tulips being off-set laterally intermediate their en s.

2. In a boiler, the combination of two upper drums having their axes in the same horizontal plane; and tubes connecting said drums in approximately said plane, said tubles being off-set laterally intermediate their enc s.

3. In a boiler, the combination of two drums having their axes in approximately 7 the same plane; and a series of banks of tubes similarly spaced connecting said drums, one of said banks being substantially in the plane of the axes of the drums and with the tubes thereof off-set laterally intermediate their ends, the off-setting equalling one space between the tubes.

In testimony whereof I have hereunto set my hand.

CARL T. GARLSON.
