14,365. Schofer, F. Aug. 3, 1910, [Convention date]. Chimneys. - The tie-pieces c connecting the walls of one or more smoke flues with the exterior walls of a surrounding ventilating-shaft are so placed as to leave the corners of the smoke flues free, and are set at an acute angle to the walls, the angles being measured in the same direction throughout. Fracture due to temperature variations is thus prevented. The Specification as open to inspection under Section 91 (3) (a) states also that the tie-pieces may be similarly placed, but at right-angles to the flue walls; this subject-matter does not appear in the Specification as accepted.
