Specification of Letters Patent.
Patented Apr. 23, 1918.
Application filed September 2, 1916. Serial No. 118,246.
To all whom it may concern."
Be it known that I, JOHN M; Fnuonns, a citizen of the United States, residing at Bufialo, in the county of Erie and State of New York, have invented new and useful Improvements in ltadiators, of which the following is a specification.
This invention relates to a radiator which is more particularly designed for use on motor trucks which are operated by explosion engines but the same is also applicable to other uses.
The objects of this invention are to provide a radiator for this purpose which is comparatively simple and durable in construction and eflicient' in operation, which can be produced at low cost, which is not liable to get out of order when subjected to severe usage and which furnishes the maxi mum eficiency for the amount of metal incorporated in the same.
In the accompanying drawings:
Figure l is a front elevation, partly in section, of a radiator embodying my improvements. Fig. 2 is a horizontal section of the same taken on line 22, Fig. i. Fig. 3 is a vertical longitudinal section taken on line 33, Fig 1. 'Figs. 4 and 5 are detached perspective views of the two sections of a water tube of the radiator. Fig. 8 is 'a fragmentary vertical section showing a modification of the means for detachably connecting the body and perforated'head of one or" the water boxes.
Similar characters of reference indicate corresponding parts throughout the several from which the cooled water is returned to the cooling oncirculating system of the ex plosior. engine.
Arranged between these two water boxes are a plurality of upright water tubes or conduits 3 preferably of sheet metal which communicate at their opposite ends with these water boxes so that the water is conducted from the inlet box 1 to the outlet box 2 and is thus cooled or lowered in tempera ture while being transferred from one water box to the other owing to the radiation of the heat of the water to the external air which is in contact with the outer surface of said tubes.
The upper water box preferably comprises an upper body 4 which is provided at its lower edge with a marginal flange 5, and 7 a'lower head 6 which is detachably connected at its margin with the flange of the companion body. Leakage between the lower head and the flange of the upper body is prevented by interposing a gasket or packing 7 between the margins of these parts, as shown in Figs. 1 and 3.
The lower water box or header comprises a lower body 8 having its upper edge provided with an external flange 9, and a head cning the structure as a whole. lln their preferred form these means comprise a plurality of tie rods 12 each of which has its opposite ends provided with external screw threads and arranged in corresponding openings in the heads and body flanges of both water boxes, inner screw nuts 13 arranged on each of said tie rods and engaging with said heads, and outer screw nuts ll arranged on.
each of said tie rods and engaging with the body flanges of the water boxes.
If desired, however, the head and body flanges of each water'box may be connected with each other independently of the other water box in which case this connection may go eilected by short bolts 12", as shown-in Each of the tubes arranged between the water boxes preferably comprises two like sections each of which has a semi-cylindrical body composed of a plurality of short semi cylindrical tube or body portions 15 which are arranged end to end in a longitudinal row, two longitudinal flanges arranged on opposite sides oil each tabs see its till
tion and each flange composed of a plurality of: short portions 16 which are arranged end to end on the same side of the tube but are connected at their inner longitudinal edges with the'longitudinal edges of the companion semi-cylindrical tube portions and a, plurality of radiating fins or wings arranged in a longitudinal row on. the outer side of a respective tube section. Each of these radieting fins or wings is arranged crosswise of the respective tube section and preferably formed integrally therewith by folding or doubling the sheet metal from which the tube sections are made at intervals so as to form a succession of plaits which alternate with the rows ottube portions and flange portions, Each of these plaits has two plies 1'3 17 the outer edges of which are connected with each other while their inneredges are connected with the opposing transverse edges of the adjacent tube and flange portions of one of the tube sections.
lChe central part of each radiating tin or wing has itsouter edge curved concentrically or substantially so relatively to the axis of the tube in its completed form, as shown at 18 and the opposite end portions 19 of each wing or fin have their outer edges arranged parallel or substantially so with the adjacent flange portions of the tube, or in other words, parallel to a line drawn diametrically through the axis of the tube.
Two tube sections of this character are placed with. the concave sides of their body portions facing each other and their flange portions in engagement and. then the latter are preferably connected by soldering to complete the tube and avoid leakage de sired the connection. between the flange por tions of two tube sections may be otherwise ehfectedn The heads 6, 10 of both water bones are provided with a plurality of corresponding openings which receive opposite ends of the water tubes, each of these openings being: constructed. to iorrn'a central circular pen tion 20 and straight or slotted portions 21, 21 arranged on diametrically opposi e of the central circular portionso as to respond in shape to the cross section oi two tube portions and the adjacent flanges oi? a water tube which is designed to bit into this opening oi? a water boa head.
. The jOl'flLtS between the water tubes and boa are preterably roads water in the several rows is such that they aaeaeer tight by solder although this may be accomplished in any other suitable inannen in the manufacture of radiators these water tubes are preferably arranged in rows crosswise of the radiator; the number of rows depending upon the desired capacity of the radiaton When a plurality of rows of tubes are employed. the disposition of the tubes are staggered in a direction fore and aft of the radiator, whereby each tube. in one transtil verse row will be arranged lengthwise in line with the space between two tubes in an adjacent row, thereby causing the air when passing from the front side to the rear side of the radiator to take a tortuous course instead. of an unobstructed path thus increasing the eliiciency of the radiator,
The tube sections of this radiator can be produced expeditiously and economicall by simple operations and the assembly of t e same with the water boxes can also be efi'ected uickly so that the radiator as a whole can no produced at low cost Furthermore the construction of the radiator is such that the same is strong and durable and not liable to leak or get out of orderwhen' subjected to undue strains, and it any repairs on the same are necessary it is'possible to conveniently dismember and. reassemble the various parts of the radiator for this purpose with out involving undue expense I claim as my invention:
A. tube for radiators comprising two sections each of which. has a longitudinal row of semi-cylindrical body portions, longitw dinal flange portions arranged at opposite edges of each body portion, and radiating fins or wings arranged on the outer sides of said body portions and flange portions,
