This invention relates to improvements in radiators, and has for its object to provide a radiator in which the headers are cut' back so that sections of the radiator can be joined together without there being any appreciable amount of space between the sections forming the complete radiator structure.

It is an object of this invention to provide a radiator section consisting of heads united by pipes, across which fins are arranged for heatradiation and distribution. The parts of the heads are formed of sheet material such as sheet steel, andare welded together to form the heads, to which the pipes are also welded.

It is also an object ofthis invention to rovide radiator sections in which the heads have cut-back portions, into whichconnecting nipples may be inserted for connecting 20. thessections of the radiator to form a complete radiator of one continuous structure, with no space therebetween.

It is a further object to provide guardmeans on the ends of the sharp heat radiating steel plates so that the radiators can be lifted without injury to the operator, as these radiators are of considerable weight and without these guards it would be dangerous to handle them.

It is a further object to provide a novel header construction of lesser width than the general width of the radiator and integrally formed with the heating pipes, as well as rigidly connected to adjacent sections of the 5 radiator.

These and other advantages will appear from the following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a side elevation showing two radiator sections united to form a single radiator unit. v

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a view showing the upper ends of two radiator sections, with a part of one radiator section in section to show the nipple construction.

Figure 4 is a view taken on the line 4-4:

of Figure 3.

Each heater section is composed of an upper header, a lower header, connecting pipes an arclrshaped passageway, having a flatbottom, the sides and top of which are formed by the wrapped plate -1, while the bottom or flat part is formed of the plate 2. When the header is used at the lower end of the radiator section or radiator unit theiparts are reversed from what they are at the upper end thereof. t The wrapped plate is shorterthan the horizontal or tube-supporting plateil. the side of the wrapped plate adjacent the plate 2 is of the same length asthe plate 2. At each end of the header is an 'end member 3 having a lateral andoutwardly inclined pro-V jection 4. This end member with the projection i completely ,incloses one end of the header and two of these end members and projections inclose both ends of the headen Each end member is attached to the plates, both 1 and 2, by means of welds 5 so that these parts, when finished, areintegral one with the other so the header is formed of one continuous piece of metal.

. lVhen the end members have been welded to the plates there is left acut-back portion the nipple is threaded into a threaded .open-.

ing or hole 7 in the end member 3. Two of these nipples are used for binding two sec- L. 4 1, v I 110113 of tne radiator, as shown in higuie 1.

nipple in the cut-back parts and rotate the nipple so that the threads on the ends of the nipple will engage the threads in the holes in the end members. And in order that the nipple may operate to connect the two adjacent sections the threads on the ends of the nipple are oppositely threaded, and the threads in the end members are made to correspond with the threads on the nipple.

The foregoing is a description of the construction of the head and the manner in which two headers may be united so that radiator sections may be united.

In order to form a complete radiator section two headers are united by means of tubes 9. Each end of each tube projects through a tube header plate and is welded thereto, as indicated by the numeral 10. These tubes may be of any convenient shape. As shown in Figure 4 they are oval. Sup ported by these tubes and in parallel relationship to the header tube plates are steel fins 11 formed from thin steel plates. T hese fins have holes therein to receive tubes.

At the ends of certain of the plates and attached to the sides thereof are reenforcing plates 12, which are welded or otherwise permanently attached to the sides of the fins. The purpose of these plates is to form a support for a cover plate 13 fitting over the ends of the radiator fins. The cover plate has lateral flanges 14, which are attached to the reenforcing plates and to the fins bymeans of bolts 15. There may be any desired number of these bolts and reenforcing plates.

The radiator isheated by means of some heating fluid, which is admitted to the radiator by means of a pipe 16 and discharged therefrom by means of a pipe 17. The heating fiuid goes into the radiator at one end and passes down through the pipes into the header at the other end.

This radiator is so constructed that either end may be used as the top or bottom part of the radiator, both headers being identical. A radiator constructed in the manner herein set out is strong, durable and is well adapted for use in manufacturing plants, power houses and the like where a large quantity of radiating surface is needed, "and where, in order to supply this surface, a rigid structure must be provided.

This rigid structure is alforded by means of applicants header structure, composed essentially of a one-piece sheet of hollow metal such as is formed by'bending and properly shaping plates of steel and welding the Two of these headers united by pipes form a rigid, strong and durable section unit, any number of which may be connected in the manner shown in Figures 1 and 3. Stress is particularly laid on the fact that all parts are welded. There are no bolts or rivets with the exception of bolts for holding the cover plate in position. This plate is merely to protect the hands of the workman when moving or installing the units.

It will be understood that I desire to comprehend within my invention such modifications as come within the scope of my claims and my invention.

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