ABSTRACT OF THE DISCLOSURE A leaf spring seal to effect sealing contact between such members as a damper blade and a frame consists of a set of leaf springs having their inner portions held together by clamping components of which one is a bar and the other the inner portion of a ledge. Either the ledge or the bar may be a part of which ever member is to be provided with the seal with the other member then provided with a seat. The outer leaf spring portions of the leaf springs are all inclined in the same direction and to the same extent relative to their inner portions and decrease in width with the outer leaf spring portion of maximum width and in sealing contact with the seat when the seal and seater in engagement with the leaf spring set then tensioned. The outer portion of the ledge is inclined in the same direction as the outer leaf spring set tensioned at least until the seal and the seat are engaged. Appropriate seal lengths consist of a series of shorter lengths with the leaf springs and clamping components thereof connected to the seal carrying member in a manner enabling thermal expansion forces to be accommodated.
