A new method of attaching the parts of the j common bedstead together, has been invented by Westley E. Merrill and Freeman Tupper, of Nashua, N. H. This method is simple as well as permanent, and recommends itself, also, for its cheapness. The rails are fastened to the posts by means of cast-iron clamps screwed upon each, which so interlock each other that a simple metal key, pressed down between the clamps, confine the rails and posts effectually together; the castings cost but a trifle, and they are very readily secured to the I posts of the bedstead, ready for use. The manner in which the head and foot board are kept in their place is still more simple, nothing being required for each connection of the board and post but two castings or pieces ol flat metal with a dovetailed groove cut upon the side of one, and a key upon the other corresponding to this groove. The parts being j secured in their position by screws, all that is necessary to put them together, is to slide the board down to its required place, and the whole will then be firmly united. The canvas which covers the springs is also buttoned upon the side rails in a very convenient manner. The inventors have taken measures to secure a patent.
