The Architectural magazine . ns; the strainingpieces but against them, and are bolted together through theking post. A wrought-iron bar extends under the king postto the cast-iron heads, and another under the struts, and to acast-iron socket, into which the tie-beam and principal rattersare inserted. The tenons of the king and queen posts (10 ) occupy the space between the ties. The struts are fixedinto iron sockets, the width of the principals, and the rods aredrawn tight by nuts and screws, on the top of the cast-ironheads. Thus the tie-beam is well supported; the truss haswidth enough to withstand all lateral strains ; and the greatestlength of the principal rafter {fg. tog) may even becambered by screwing up the rod at //. It is in this part thatroofs so often fail; and in many cases it is owing to the assistantqueens not straining in the truss; consequently the tie-beamsinks, the queen post follows, and the principal rafter becomeshollow.
