Thus it will be understood that theboiler is made up of a number of these vertical■connections (called sections), plaied side by side,ithus forming the complete boiler. Each of the c:)nneotlng bends is held up to its seat by four b^lt^, two bolts to each ball-shaped heads of these bolts are receivedinto similar shaped sockets in the heade/s. Inorder to remove a package of tubes, two connect-ing bends must be removed from the front andtwo from the rear of the same package; one ofthese connecting bends, at one end, of course,connecting the header with a header Immediatelybelow it, while the second bend forms the con-nection to the header above. In the first place, before removing, sa,y, thetwo front connecting bends, eight nuts must beremoved, then the bends are lifted out of place;next the eight bolts are removed, and then thefour packing rings are taken out of their
