SHEET-M ETAL RADIATOR.

SPECIFICATION formingpart of Letters Patent N 0. 670,110, dated March 19, 1901.

Application filed May 15, 1900.

To all whom it may concern.-

Beit known that I, CHARLES PHELPS, acitizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented certain new and useful Improvements in Sheet-Metal Radiators, of which the following is a specification.

My object is to provide an inexpensive device for holding the sides of a sheet-metalradiator-section rigid at the point where coupling is made between two radiator'sections and at the same time to so construct such parts as to adapt them for being connected by means of ordinary push-nipples, and, further, in this connection to provide devices of this class in which the expense of drilling holes for the circulation of water or steam therethrough is avoided.

My invention consists in certain details of construction, arrangement, and combination of the parts whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows in perspective my preferred form of base for holding the sides of a sheetmetal radiatorseparated and providing means for attaching other radiator-sections thereto. Fig. 2 shows a vertical transverse sectional view of the lower portion of a sheet-metal radiator-section having therein my preferred form of device for rigidly supporting the sides of the sheet-metal radiator-section at the point where same is coupled to an adjacent radiator-section and also showing in one end of said device a push-nipple.

Referring to the accompanying drawings, 1 have used the reference-numeral10toindicate a sheet-metal radiator-section, and at the central portion of each side thereof near the lower end is an integral outwardly-projecting circular part 11, having a round opening 12 in its central portion.

The base for holding the sides of the radiator-section rigid at the point where two radiator sections are coupled together comprises a cast-metal collar 13, having the flatfaced smooth outer end 14, with a concentric Serial No. 163742- (No model.)

opening therein. On the other end of the collar 13 a series of notches 15 is formed.

provided to mate with the collar just de-- scribed, and obviously with the construction shown the notched edges of these collars may come together without-the possibility of the projections of one entering the interdental spaces of the other. The central opening through these collars is preferably slightly larger in diameter than the diameter of the opening 12, thus leaving a flange in the sheetmetal sides of the radiating portion surrounding the opening. In use two of these collars are placed in the shoulders formed by the outwardly-projecting portion 11, with their smooth faces outwardly, and the said collars are of such a length that when combined they will entirely [ill the space between the parts 11 of the opposite sides of the radiator-section.

The numeral 16 indicates a push-nipple of ordinary construction, and obviously when this nipple is forced into one of the openings 12 the flanges surrounding said opening will be bent inwardly to lie parallel with the inner surface of the base 13, and obviously a tight joint will be provided at this point on account of the elasticity or resiliency of the said sheet-metal flange, so that when two radiator-sections are coupled together in the manner described ajoint will be provided that is rigid and firm and not liable to leak.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States therefor, is

1. The combination, with a sheet-metal radiator-section, of a base, to enter between the sides of the sections and hold them separated, said base comprising two rigid collars having smooth outer ends and notches on their inner or meeting ends leading from the interior of the collars outwardly into the section and of such shape as to be incapable ofadmitting the projections of one collar into the interdental spaces of the other.

2. The combination, with a sheetmetal ml ranged on lines other than radial, the notches didtor-section, of it base, to enter between the on one standing in an opposite direction from sides of the sections and hold them separated, the notches on the other. said base comprising two rigid collars having CHARLES PHELPS.

5 smooth outer ends and notches on theirinner or meeting ends leading from the interior of the collars outwardly into the section, and ar- Witnesses:
