The hist men-tioned form is the one shown in the drawing. In either casethe lower part of said plate rests partly upon the base of therails, and partly upon the outside Up of the chair, as the ig. 2 is a view of inside plate D, which is applied oncesi nner side of the joint This plate must fit into the re-the side of the rail, as its upper part can not projectateit^y beyond the head of the rails, jr it would interferewith e shegellanof the wheels. Ai-d its lower part, like thelower part of plate C, rests partly upon the base of the rails,and partly upon the inside lip of the chair, as shown in themodel. From the inner side of this plate, projects twostrong horizontal tongues C C, which pass through slots inthe ends of the rails, and corresponding ones in the outsideplate C. These tongues rest upon projections, which areprovided on the chair to stand up outside of the plate C, toact as hearings for the tongues C C, and serving, also, inpart, to cenfinethe plate C. The ends of the tongues arefurnished with vertical slots to receive keys, which ar«driven through them, and corresponding vertical slotsin thechair. The rails and chair are secured to the joint tie byspike3 pa
