' E. RICHARDSON ENAMELED RADIATOR Filed July 5, 1921 Wh-NEss ax/MW Patented den. 22, ieaa ERNEST RICHARDSON, 01 COLLEGE HILL BOROUGH, PENNSYLVANIA.

ENAIIIELED RADIATOR.

Application filed July 5,

To all whom it may concern:

Be it known that I, ERNEST RICHARDSON, a citizen of the United States, residing at College Hill Borough, Beaver County, and a State of Pennsylvania, have invented new and useful Improvements in Enameled Radiators.

My invention relates to sectional radiators heated by steam, or water. The object of this invention is to provide an enameled sectional radiator on which the enamel will not be cracked or broken-at the joints between the sections.

Referring to the accompanying drawing, Fig. 1, is a side elevation of a radiator containing my invention, parts being omitted and broken away; Fig. 2, an end elevation of one end of one section of said radiator; and Fig. 3, a vertical enlarged section through the upper end of two assembled sections of my radiator; Fig. 4 is a section on the line IV-IV of Fig. 2.

On the drawing, I show a metal radiator built from a number of hollow sections or units 1. These sections, except the end ones, are interchangeable. These have at opposite sides at each end a lug or boss 2 with its outer face 3 parallel with the unit bearing the same. These bosses and faces are correspondingly 80 arranged on the units so that, when the units are assembled in a series, the faces 3 on adjacent units will be contiguous or will fit, one on the other. These faces have correspondingly located holes e1E communicating with the as steam or water passages 5 in the heads 6 of the units. The holes 3 in each pair of adjoining bosses 8 contain an oppositely tapered nipple *5 which fit the said holes to prevent Serial No. $82,303.

the escape of fluid through the holes l to the faces 3 and the exterior of the radiator.

units for the purpose of binding the units into a larger rigid unit or radiator.

In the manufacture ofv each unit it is, except on the faces 8, coated with enamel and fired or burned in any suitable manner. The meeting faces 3 not having any enamel thereon, there will be no cracking or chipping of the enamel at or around the joints of the contiguous bosses 2. If enamel were. on the faces 3, it would be cracked or chipped away in spots by the pressure due to the clamping action of the bolts 11 or to the action of the heat in the joints.

The enamel may be left off from the wings 10 on the parts on which a head or nut on the bolts 11 bears in order to prevent the cracking and chipping of the enamel around the nuts and bolt heads.

I claim June, 1921.

ERNEST -RICHARDSON.
