The accompanying engraving clearly shows a shingling bracket, recently patented by Mr. William H. Smerdon, of Taunton, Mass. The shorter arms of the two levers, which are pivoted together, are provided with spurs. The arm of the upper or horizontal lever is passed under a shingle, when its two spurs enter the upper and lower shingle, the spur of the other arm entering the opposite surface of the clasped shingle. An upright, forked at its upper end, is pivoted to the long arm of the horizontal lever, and is formed at its lower end with a wide chisel edge, having two or more spurs that engage with the finished roof. Above the chisel edge the upright is widened and formed with an oblong aperture, having on one edge L-shaped lugs, with which engage lugs on the lower portion of the inclined lever. To apply this bracket, the short arms are made to clasp the shingle, when the lower portion of the inclined lever is raised, and the proper lugs are brought into engagement to hold the parts in their relative positions. The boards to form the staging are then placed on the horizontal lever, the spurs on the upper edge of which hold them securely. The spurs on the chisel edge prevent the upright from slippin/l.
