HEATING RADIATOR Filed June 25. 1951 Patented Dec. 13, 1932 ARTHUR ABBOTTS, OF FAIRFIE'LD, CONNECTICUT HEATING nAnrAron Application filed June 25, 1931. Serial No. 546,679.

This invention relates to new and useful improvements in heating radiators.

An object of the invention is to provide a heating radiator including means for bringing, about a definite and increased circulation of air through and about the radiator and for providing additional radiating surface whereby a greater quantity of air will be brought into contact with the hot or heated surfaces of the radiator and whereby heat from the radiator will be more quickly transmitted to the surrounding atmosphere.

Another object is to provide a radiatorineluding a pair of headers each having a cor- 5 responding number of tapered openings therein and pipes extending between said headers and having. tapered ends fitted and cemented into said openings and connecting said headers to form a unit with them and providing passages between the headers.

A further object is to provide a heating radiator including a pair of headers or manifolds and a plurality of pipes connecting said headers and each forming an independent passageway between the headers whereby the clogging of one of said pipes by condensation will not affect the operation or efficiency of the others. e

Other objects and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. It is, of course,to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims to which claims reference is to be had for a definition of the invention.

In the drawing:

Fig. 1 is a view partly in top plane and partly in transverse section showing my improved radiator, the portion of the figure 4 shown toward the right being taken. substantially along the line 11 of Fig. 2;

Fig. 21s a view partly in side elevation and partly in vertical section, the portion of the figure shown toward the right being taken substantially along the line 22 of Fig. 1;

Fig. 3 is a detailed sectional view showing the openings in the air circulating tubes forming part of my radiator;

Fig. 4 is a side view of the inner of said tubes, the view being taken looking from the (515 right in Fig. 3; and

Fig. 5 is a detailed sectional view showing .the connection between a radiator pipe and header. 7

Referring in detail to the drawing the improved radiator of' the present invention is shown as including a pair of vertically disposed headers 6 and 7 each including a bracket 8 through which extend bolts 9 whereby the radiator may be easily and quickly bolted or 165 secured inplace. The headers 6 and 7 are each provided with screw threaded or tapped openings at both their upper and lower ends andas shown in the example in the. drawing an inlet pipe 10 is threaded-into the upper end of the header 6 while an outlet pipe 11 is threaded into the lower end of the header 7 the lower end of header 6 and the upper end of header 7 being shown as closed by plugs 12. Since the headers are each adapted to have a pipe connected with either or both of their ends it will be obvious that other arrangements for the inlet and outlet pipes for steam or other heating medium may be made as desiredor as convenient in the location in which the radiator is to be used.

- In one of its sides each header is provided with a plurality of tapered openings 13 and it will be noted that each opening is in communication with the entire interior of the header, there being no dividing or partitioning means within the header. Extending between and connecting the headers and form ing passages between the headers are a series of pipes 14: and each pipe has its end tapered as at 15 (see Fig. 5) to be received in a tapered opening 13 in the header. The tapered ends of the pipes are secured in the openings 13 as by means of an iron or waterproof cement 16.

I have found that the construction just described is of great strength and not likely to be loosened or weakened by vibration and not therefore likely to leak. It will be noted that there is an entire absence of union fittings or other threaded connections between sible.

the pipes and the headers which are likely to work loose under vibration and leak, and it will further be apparent that the pipes and headers may be readily and quickly connected by the means described. With this construction the radiator can be made more compact. VVith the structure described tie-rods or other securing means between the headers is unnecessary since the pipes serve to connect the headers and with them form a radiator or heating unit.

As each header is entirely open in its interior and not provided with dividing or partitioning means it will be apparent that the circulation between the headers is independent for each pipe 14. That is, should the lowermost pipes become filled with water of condensation, it will be apparent that circulation between the headers and through the other-pipes is not at all interfered with. In this connection I have shown two sets of pipes each set including the desired number of pipes arranged one over the other and all extending substantially horizontally.

, Extending vertically and arranged between the headers 6 and 7 and disposed on and supported by the pipes 14 are a plurality of heat transfer units 17 Each of these units 17 includes an outer tube 18 and an inner tube 19. The tubes of each unit are necessarily considerably different in diameter whereby the inner tube is spaced from the outer tube and a passage is provided between the tubes as at 20.

The pipes 14 extend through the heat transfer units formed by the

tubes

18 and 19 and to this endeach tube 19 is provided with a plurality of spaced openings 21, the said openings being provided in opposite side 'walls of the tube and in spaced relation.

Also, each opening is preferably surrounded by a flange 21a as clearly shown in Fig. 3 and the diameter of each opening 21 is such that the surrounding flange engages the pipe 14 and conducts heat therefrom.

The inner tubes 19 are held spaced from the outer tubes 18 as by any suitable means such as pins 22 and each of the tubes 19 is provided on opposite sides with an elongated slot 23 which slot is of such length as to receive a plurality of the horizontal pipes 14. It will be understood that owing to the employment of a slot 23 it is not necessary that carefully spaced holes be provided or that they be carefully aligned with openings 21 for the passage of the pipes 14 and accordingly a manufacturing tolerance is permis- The slots 23 are surrounded by flanges 24 which flanges will also engage the pipes 14 and conduct 'heat from them.

It will be appreciated that the heat transfer units 17 will conduct a considerable quantity of heat from the horizontal pipes 14 and it will 'be'noted that a number of these units are employed; As here shown the units are arranged'in such relation that the outer tubes ly arranged headers, inlet lngs to and from said headers, a plurality of units at the lower ends thereof will be heated progressively as it passes up through the units through and about the

tubes

18 and 19 and that a circulation of air will be established through the units. Since the tubes conduct heat from the pipes 14 a greater heating or radiating surface will be obtained and since a greater circulation of air is set up a greater quantity of air will be drawn through and aboutthe units and have heat transferred to it. The pipes may be made of different materials as desired but it is preferred that the pipes 14 be made of brass and the upright

air conducting tubes

18 and 19 be made of copper as this is a very good conductor of heat and will more readily conduct the heat from the pipes 14.
