Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed April 26, 1905. Serial No. 257.469.

To all whom it may concern.-

Be it known that I, FREDERICK LAMPLOUGH, a subject of the King of Great Britain, residing at Willesden, in the county of Middlesex, England, have invented new and useful Improvements in the Construction of Radiators, Steam-Condensers, and the Like, of which the following is a specification.

The invention relates to improvements in the construction of radiators, steam condensers, and the like, whereby a more rapid cooling effect is obtained than with the constructions hitherto in use.

I will describe my invention by the aid of the accompanying drawings, in which Figure 1 is a sectional front view, and Fig. 2 a cross-section, the gills being omitted, of parts of a radiator constructed according to my invention. Fig. 3 is a vertical section, and Fig. 4 a horizontal section, of one of the gilled tubes and its fittings. Fig. 5 is a vertical section of the gilled tube without its fittings, and Fig. 6 is a vertical section of one of the flanged ferrules used. Fig. 7 is a sectional elevation, and Fig. 8 is ahorizontal section, of a tube, showinga slight modification.

I will first describe the construction represented at Figs 1 to 6. a is a tube provided with gills b and which may be of ordinary construction. I preferably use a copper tube a with metal gills b sweated or brazed to the same to form radiating-surfaces, as is well understood. The ends of this tube a according to my invention are flanged, as shown at c, and a ferrule d, having flanges e, is inserted in said tube, the plates f of the radiator or the like being between the flanges c and e and the whole sweated or brazed together to make 12: perfect hermetic joint with the plates f or By the above construction the tube-plates are securely held between the flanges, and the tubes thus form stays between the tube-plates. The principal point of the invention, however, is the arrangement for doing away with the center core or body of water to be cooled in the tube, so as to cause a thin film of water or steam only to be exposed for cooling at any time. To achieve this, I make three or more indents or corrugations g in the tube a, near the top and bottom thereof, and fill up the center of the tube a with an inner tube h,

stopped at both ends with the exception of small pin-holes 21, which are for the purpose of preventing the formation of a vacuum in the tube a either in the course of manufacture or working. The inner tubes it may, however, be filled with water to assist the cooling, in which case when the radiator is applied to a car and the latter is standing still the Water in such tubes would continue to cool and it would act as cold storage and at the same time utilize that amount of space. To further break up the steam or water, I may adopt the modification shown at Figs. '7 and 8, in which case I fit a corrugated tube in the annular space between the inner tube It and outer tube (4, whereby the indents or corrugations g in the outer tube a may be dispensed with. In this modification the ends of the tubes (4 are flanged and fitted with flanged ferrules and all the parts are sweated together, as described with respect to Figs. 1 to 6.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a radiator,steam-condenser or the like, the combination with gilled tubes, of a flange at each end thereof, a flanged ferrule fitted into each end of said tubes, tube-plates located between said flanges, a tube closed at both ends occupying the larger portion of the bore of the gilled tube and corrugations for centralizing said inner tube, the whole being sweated together to make a perfect joint between the parts, substantially as herein set forth.

2. In a radiator, steam-condenser or the like, the combination with gilled tubes, of a flange at each end thereof, a flanged ferrule fitted into each end of said tubes, tube-plates located between said flanges, a tube closed at both ends occupying the larger portion of the bore of the gilled tube, and a corrugated tube fitting between said tubes, the whole being sweated together to make a perfect joint between the parts, substantially as herein set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

FREDERICK LAMPLOUGH. Witnesses:
