The last men-tioned form is the one shown in the drawing. In either casethe lower part of said plate rest3 partly upon the base of therails, and partly upon the outside lip of the chair, as Fig. 2 is a view of inside plate D, which is applied onthe inner side of the joint This plate must fit into the re-cess in the side of the rail, as its upper part can not projectlaterally beyond the head of the rails, or it would interferewith the flanges of the wheels. 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 bearings for the tongues C C, and serving, also, inpart, to confine the plate C. The ends of the tongues arefurnished with vertical slots to receive keys, which aredriven through them* and correspondingverticalslotsin thechair. The rails and chair are secured to the joint tie byspi
