The list men-tioned form is tbe one shown in the drawing. In either casethe lower p*rt of said plate rests partly upon the base of therails, and partly upon theoutside lip of the chair, as shownin Fig. 3,. 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 apper part can not projectlater^y beyond the head of the rails, or it would interferewith e shegetlanof the wheels. AlcI its lower part, like thelower part of plate C, resis partly upon the base of the rails,and partly upon the inside lip of tbe 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 mis, and corresponding ones in the outsideplate C-. Tliese 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 cenfine the plate C. The ends of the tongues arefurnished with vertical slots to receive keys, which aredriven through them, and corresponding vertical slotsin thechair.
