ROME-TURNEY. A IATOR -01 NEWYOBIQQ: a

To all whom it may concern:

Be it known that I,-'FRANK H. STOLP, a citizen of the United States, residing at Rome, Oneida county, State 9f New York, have invented certainnew and useful Improvements in Radiators, the following being a full, clear, and exact disclosure of' the one form of my invention which I at present deem preferable.

For a detailed description of the present form of my invention, reference may be had to the following specification and to the ac-' given capacity, particularly the transverse dimensions in the direction of air flow, and I therefore employ extremely thin material, say about seven one-thousandths of an inch in thickness, comparable to paper, and provide a construction which, with such thin metal will still be strong and rugged. I

employ but a single row of water tubes and the parallel radiating surfaces are not more than one-eighth of an inch apart. By these means I am enabled to reduce by one-half the transverse thickness of a radiator having a given capacity, the standard trans-:

verse thickness of my radiator being but one and one-half inches.

'Referring to the drawings, A is a strip of very thin metal, preferably copper, which is folded .or crimped' at exact inter-' vals, the crimps being about one-eighth of:

an inch or less in height and each being split and'expanded atiits center into a tube B of a double arch form," as appears in Fig. l.- Previous to-crimping, the edges of the strip A are folded over as shown at a to form a bead and the bead is then folded into the crimps. tube gives strength, and the tube" is also protected on each slde by the unsplit portions 6, b of the crimp, while the bead gives strength and stiffness to the exposed, edges of the strip and when folded into the crimp gives strength and stiffness to its exposed RADIATOR.

end. These features are of importance in connection with the thin material. The upper edge of the tube on each side is curved upward, as shown at c in Fig. 5, and slightly dished, see (Z, Fig. 3.

A series of strips A, eachof the desired PatentedDecjg1912.

length of the radiator, are laid one upon another as shown in. Figs. 2, 3 and 5, the

tubes B ofone strip registering with those of the next and the upwardly curved and dished extremity of 'one tube entering a slight distance into the larger base opening of the one adjacent to it in the next strip. This produces a continuous duct from top to bottom of the pile of strips, while between the ducts soformed extend the thin strips about one-tenth of an inch apart serving'as radiating surfaces exposed to the air which passes through from front to back of the radiator. This radiating surface in the aggregate is greatly increased by the multipliclty of thin strips containable in a given space. stead of the interior of the strips and the strips themselves are in unbroken metallic connection with the tubular portionv so that the heat of the water in the tubes is readily conducted to and throughout the strips. My radiator is therefore of the same temperature front and back, the air being free to flow through without becoming over- The heat is also on the surface in-- heated in its passage but capable of abstractof the-radiating surfaces.

To seal the tubes against leakage, I dip one sideof an assemblage of strips in-a bath of solder and the thickness is so small that the solder will be drawn by capillary attraction up into all of-the crevices. between succeeding tubes and effectively seal them. I prefer, however, to add'as a precaution an interior lining C. This is made of similar thin material folded over as shown in Fig. 4 to form an archedtube fitting easily into the sectional duct formedby' the tubesB. The liningC is 'in'sertedfafter the strips have been inserted and before-the soldering above referred to" and without having its overlapping edges previously soldered; JBy.

thismeans the linings can enter; without "ob struction; moreover, being'of such thin material they can be thrust into the ducts in the previously assembled pile. of plates as distinguished from first setting up the lining tubes and forcing the strips down oventhem ing the heat uniformly from the entire area After the linings are in place, the soldering operation will follow which will simultaneously seal the overlapping edges of the lining tubes, seal together the tubes B, B and secure the tubes B, B to the lining.

A radiator constructed as above described presents a neat a pearance, the edges of the strips being stiflfiand straight and uniformly spaced; while it is also strong and rugged in spite of the paper-like thinness of the material employed in its construction and the water ducts are protected against the leak-producing effect of external blows. It will also be manifest that the thin'material would not permit of the tubular sections being struck up from the strip itself without the fold or crimp to furnish the necessary material for the tubes.

The oblong form of the ducts, with their longer dimension lying across the strips or plates, but of less length than the width of i the strips or plates, aifords a free space for the circulation of air through the radiator from front to back. I also prefer that the strips shall be superposed in a horizontal series, so that their integral tubular extensions will be alined to form fluid ducts.
