T 0 all whom it may concern:

Be it known that 1, France D. SoHENoK, a citizen of the United States, and a resident of Dayton in the county of Montgomery and State of Ohio,'have made a new and useful Invention in Radiators, of which the following is a specification.

The invention relates to radiators designed for use with corrosive liquids. It has for its principal objects; the provision of a radiator of improved construction,- (1) illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation partially in section showing a radiator made of three sections involving my improvement. Fig. 2 is a partial end elevation of one of the sections disassembled. Fig. 3 is a side elevation partially in section of a modified radiator construction involving a larger number of sections. Fig. 4 is an end elevation of one of the end sections. Fig. 5 is a partial side elevation and partial section through the section of Fig. 4:. And Fig. 6 is a transverse section through the section of Fig. 4 on the line VI-VI.

Referring to Fig. 1, the numerals 1, 2 and 3 represent radiator sections secured together by means of tie rods 4 located in passage 5 adjacent the ends of the sections, only the tie rod at the lower end of the sections being shown in Fig. 1 but the other end being of similar construction and similarly arranged.

The sections 1, 2 and 3 are of acid resisting metal preferably of the composition known by the trade name of Duriron and comprising a high silicon iron which is exceedingly resistant to the corrosive action of liquids such as the various acids and alkalis. radiator is designed either to carry the 1921. Serial no. 467,309.

corrosive liquid which is to be heated or cooled or else to carry theheating or cooling liquid and be immersed in the-corrosive liquid to be heated or cooled. The radiator is so constructed that in either case the tie rods 4 and the threaded parts which cooperate therewith are perfectly protected from the action of the corrosive liquid. This is desirable andin' fact necessarysince a relatively high degree of tensile strength is'required in-the tie rods and their nuts and metal suitable for this purpose having the necessary degree of tensile strength and readily machinable is not acid-resisting. The tie rods. and bolts are; of ordinary wrolught material such as wrought iron or The various sections ,of the radiator are provided with the passages 6, 7- and 8 which communicate at their ends as illustrated wh le the sections are fitted togethensuitable packing discs 9 being employed at the joints in order to prevent leakage, such discs being made of packing material which will resist the corrosive action of the particular liquid to which the radiator is'to be exposed. The tie rod passages 5 are placed relatively close to the ends of the radiator sections and the packing discs 9 and; 10 serve to prevent any leakage into the recesses 5. either from the interior of theradiator or from the exterior thereof. The ends of the tie rods are engaged by wrought metal nuts 11 around which are, cast the protecting caps 12 preferably of the same acid resisting material as the radiator sections. Suitable packing discs 13 are provided between these nuts and the adjacent surfaces of the radiator sections so that when the nuts are screwed up tight no leakage can occur to the recesses or passages 5.

In the construction shownin Figs. 3 to i 6 there are eight radiator sections including the end sections 14 and 15 and the intermediate sections 16, the entire set being held together by means of the tie rods 17 provided with Wrought metal nuts and pro-' let and outlet portions are placed at thesame ends of the radiator instead of at the opposite ends. The tie rod passages 22 (Figs! 4 and 5) are located somewhat differently from the construction of Fig. 1, being placed below the ends of the radiator passage 23 instead of above as in the construction of Fig. 1. At tlie inlet and outlet ends of the sections, 14 and 15 the radiator passage divides into the two branches 24 and 25 as indicated in Figs. 4 and 6 in order to pass around the tie rod passages or perforations 22. In both constructions the tie rods are placed close to the extreme ends of the radiator where they will be most'effective in giving the necessary tightness to the joints and in each case the tie rods or bolts-with their nuts are protected from the corrosive action of any liquid either inside or outside the radiator. The packing construction which is not illustrated in the second form of the construction is similar to that described in connection with .the first form.

Another distinction over the construction of Figs. 1 and 2 resides in the fact that each of the sections 14-, I5, 16, consists of one vertical pipe, while in the construction of .Figs. 1 and 2 the sections 1,2 and 3 all consist of two vertical pipes (see Fig. 2).

In order to prevent air bind and consequently water hammer for moist steam or liquors going through the radiator, the vent holes 26 (Fig. 3) are provided at the ends of the sections. This feature of the con'-,

struction adds greatly to the effectiveness and value of the construction and constitutes one of the important details of my invention.

What I claim is: 4

1. In combination in a radiator, a plurality of hollow parallelcast sections of noncorrosive metal with lateral openings in the ends so as to form a continuous passage when the sections are fitted together, and

. subscribed my name .rod passages, tie rods of wrought metal extending through saidpassages for clamping the sections together, and means forpreventing access of the corrosive liquid to the ends of said tie rod passages.

2. In combination in a radiator, a plurality of hollow parallel cast sections of noncorrosivemetal with lateral openings in the ends so as to form a continuous pass age when the sections are fitted together, and each provided with transverse perforations lying to oneside of said lateral openings in the ends and a dapted to aline and provide tie rod passages when-the sections are fitted together, packing means between the sections around the openings in said ends and around the ends of the perforations "adapted to seal off the radiator passage from the tie rod passages, tie rods of wrought metal extending through said passages for clamping'the sections together, and nut members protected by non-corrosive material for engaging the ends of'the tie rods and forming closures for the ends of said tie rod passages. L In testimony 'whereof, I have :hereunto this 2nd day of May,
