Century Dictionary and Cyclopedia
- n. A short beam attached to the foot of a principal rafter in a roof, in place of a tie-beam. Hammer-beams are used in pairs, and project from the wall, extending less than half way across the apartment. The hammer-beam is generally supported by a rib resting upon a corbel below, and in its turn forms the support of another rib which constitutes, with that springing from the opposite hammer-beam, an arch. Although occupying the place of a tie in the roofing, it does not act as a tie; it is essentially a lever, as is shown in the figure. Here the inner end of the hammer-beam, A, receives the weight of the upper part of the roof, which is balanced by the pressure of the princinal at its outer end.

- n. (Gothic Arch.) A member of one description of roof truss, called
