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 pro|ectlaterally beyond the head of the rails, or it would interferewithte shegenanof the wheels. And 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 arcprovided on the chair to stand up outside of the plate C, toact as bearings for the tongues C C, and serving, also, inpart, tocenfme the plate C. The ends of the tongues arefurnished with vertical slots to receive keys, which are,driven through them, and corresponding vertical slots in thechair.
