The bist men-tioned form is theoue shown in the drawing. In either casethe lower part of said plate rests partly upon the base of therails, and partly upon theoutside lip of the chair, as Fir. 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 protectlaterally beyond the head of the rails, or it would interferewithte shegeflanof the wheels. its lower part, like thelower part of plate C, rests partly upon the base of ihe rails,and partly upon the inside lip of the chair, as shown in themodel. Frcm 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, tocenfine the plate C. The ends of the tongues arefurnished with vertical slots to receive keys, which ar«driven through them, and correspondingvertical slntsin thechair.
