103,492. Pease, E. L. Jan. 15, 1916. Joints and connexions, radiators.-Relates to the fixing of heat radiating gills to metal plates forming the walls of a radiator or other heat exchanger or of a furnace. The gills are received in slits which are sawn or similarly cut in the face of the plate. Figs. 10. and 11 indicate methods of fixing a gill b in a plate a. A slit s may be cut of a width less than the thickness of the gill, the plate being then bent to open the slit as shown at t, whereupon the slit is traversed by a tool of a width equa to the thickness of the gill and assumes the form shown at u. When the plate is straightened, the slit is of the shape shown at v, and receives a root w, Fig. 10, formed by grooving the gill b. The gill may be inserted in re-straightening the plate, or may be driven in from one end. The root w may be formed as shown in Fig. 11, by a thickening of the gill b, in which case the first slit s is of a width equal to the thickness of the gill, and the slit u of a width equal to the thickness of the root. A thin plate may be bent and a slit of a width equal to the thickness of the gill may be cut while the plate is so bent, one cutting operation only being required.
