Description

Aug. 11, 1931. o. R. LUDWIG FIN RADIATOR Filed Jan. 24, 1950 l f I Patented A'ug. ll, 1931 PATENT OFFICE 1` UNITED STATES OSKAR It. LUDWIG, OF GARY, INDIANA FIN RADIATOR l l Application llled January 24, 1930. Serial No. 423,031.v
the steam chamber or chambers are adapted to be threaded through fin units of any re quired number, with said Asteam chambers adapted to be connected directl with steam supply and outlet pipes by or inary steam fittings.
It is an object of this invention to provide a fin radiator wherein a iin supporting steam chamber is adapted to be connected by means of ordinary steam fittings directly in asteam pi e line.
t is also an object of this invention to provide an improved simplified type of iin radiator comprising a plurality of 1in units having internally threaded collars integral- 42li ly formed thereon through which an externaln ly threaded steam chamber pipe is adaptedto be threaded to complete the radiator.
It is a further object of this invention to l provide an improved type of fin radiator of 80 the headless type wherein one or more externally threaded steam chamber forming pipes are adapted to be threaded through internally threaded collars integrally formedv on fin units to hold the fin units in assembledrelation to provide a fin radiator.
It is furthermore an object of this invention to provide -a simplified inexpensive type of fin radiator wherein the ordinary headers are omitted by connecting the ends of a steam chamber directly in a steam pipe line by means of ordinary pipe fittings, said steam chamber being external-ly threaded to permit the same to be threaded through a series of adjacently disposed fin units to hold the same in assembled relation on the steam chamber to provide a fin radiator of variable radiating capacity, depending vupon the number of fin units employed.
It is an important object of this invention to provide an improved type of simplified liny radiator broken away.
expensive fin radiator adapted to vbe conveniently assembled and consistingof )one or more externally threaded vsteam chamber units adapted 'to be engaged through -'internally threaded sleeves of a plurality of yiin@ unitsto provide a variable radiating capacity fin radiator of either the unitary or multiple steam chamber type. y y Other and further important objects of this invention will be apparent from the dis`l M closures in the specification and drawings. The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.
On the drawings:
Figure l is a longitudinal, vertical section taken through an improved type of fin radia- .-tor embodying the principles of this invention, with the intermediate portion of the Figure 2 is a transverse, longitudinal section of the fin radiator taken on line II-II of Figure 1.
Figure 3 is a sectional View of the fin radiator taken on the line III-III of Figure 2.
Figure 4 is a fragmentary, detail sectional view taken on line IV-IV of FigureL 3, showing a fragmentary portion of a steam chamber pipe in elevation. z
` s shown on the drawings:
The improved fin radiator of this invention is adapted to be connected by means of ordinary steam fittings or couplings directly in a steam pipe line. The use of the ordinary type of radiator headers is thereby entirely obviated. L'
The improved fin radiator of this invention may be either of the unitary steam chamber type or of the multiple steam chamber type.
In the present showing of the invention, a multiple steam chamber type fin radiator is illustrated and described and comprises a pair of externally threaded lsteam chamber pipe sections l which constitute the body of the radiator. The pipe steam chamber sections 1 form the steam chambers for the radiator and are adapted to be used in connection with a plurality of fin units, each of which comprises a main body plate 2 having integrally formed on the longitudinal margins thereof Wing plates or flanges 3 which are disposed at an angle with respect to the iin body plate 2. If desired, the n plates may be of any desired design or configuration.
Integrally formed on one side of each of the fin bodyl plates 2 are internally threaded sleeves or collars 4.
A plurality of the improved fin units are placed adjacent one another, as illustrated in Figure 1, and the steam chamber pipes 1 are threaded through the internally threaded collars forming part of the fin units. Engaged on one end of each of the steam chamber pipe units 1 is a lock ring 5, against which the'endmost fin unit at one end of the radiator is adapted to seat. The locking ring 5 may be of the hexagonal nut type or any other desired construction.
The improved type of iin radiator may be produced With a single steam chamber or pipe section 1 or with a plurality of steam chamber sections, thereby aording an arrangement permitting the lin radiato-r to be furnished in different lengths and sizes to vsuit conditions.
To build and assemble a iin radiator, a plurality of fin units are placed in stacked relation, With the threaded openings in axial alignment. The fin units are clamped in ,abutting aligned relation by any suitable type of clamps or holders, after which the externally threaded pipes 1 are snugly threaded through the internally threaded axially aligned collars 4, with the ends of the pipes projecting beyond the two outermost iin units. Any number of fin units may be thus assembled to provide a fin radiator of variable radiating capacity. The lock members 5 are threaded onto the projecting ends of the pipes 1 at one end of thev iin radiator, tightly against the outermost fin unit to tightly clamp the various iin units together locked in position upon the pipes 1. This completes the assembly of the fin radiator, which may have the ends of the pipes 1 connected With the steam supply and outlet pipes by ordinary steam fittings.
It Will, of course, be understood that various details of construction may be varied through a Wide range Without departing from the principles of this invention, and it is, therefore, not purposed to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
I claim as my invention:
1. A fin radiator comprising a plurality of fin units having threaded openings there in, a threaded steam chamber Section threaded through said fin unit'openings and adapted to be connected in a steam pipe line by ordinary pipe iittings, and means adjustably engaged on said section for holding the n units locked in position.
2. A tin radiator comprising a plurality of fin units, a steam chamber section projecting through said fin units, and means for removably locking the iin units in assembled relationon said section to provide a fin radiator of variable radiating capacity.
3. A iin radiator comprising a plurality of fin units, internally threaded collars forming a part thereof, an externally threaded pipe threaded through said collars and forming the steam chamber of the radiator, and means for locking .the iin units With respect to said pipe section. f
4. A iin radiator comprising a plurality of iin units, internally threaded collars on each of said units, and a plurality of externally threaded pipe sections threaded through the collars of said fin units to form the steam chambers of the fin radiator.
5. A iin radiator comprising a plurality of iin units, each comprising a body plate, flanges integrally formed thereon, an internally threaded collar integrally formed on said body plate, and a threaded steam chamber section threaded through the collars of said fin units to hold the same in clamped contacting relation.
6. A fin radiator comprising an externally threaded steam chamber,.a plurality of iin units threaded thereon in abutting relation, and means for locking the fin units in position on said steam chamber.
7 A iin radiator comprising an externally threaded steam chamber, a plurality of abutting flanged fin units having removable threaded engagement therewith and means co-acting with one of said units for locking the units in position.
In testimony whereof I have hereunto sub-- scribed my name at Chicago, Cook County, Illinois.
