Application filed March 24, 1920.' Serial No. 368,294L.

To all 'witam it 07m3/ amica/m: Be it known that I, JEAN Barrrsfrn DOM- INIQUE Lr'ion CHARDARD, cltizen of thel Republic of France, and/resident of Paris,

elements of variable form and positioncurved, straight, Vertical, 'horizontahv etc.,y mounted on collectors in a mannerenabhng` them to be readily `dismantled; andv the characteristic features' of the radiator vare the mode of assemblage and the provision of a regulator by means of which it isposs1- ble to vary the quantity'of water passing through each element and, in case of necesr si'ty, to stop the circulation of water therein,

(for instance in case of a leak), without `interfering with elements.

The accompanying drawing` illustrates, by way of example, a radiator with the features forming the subject of the'present'invention.

Figure 1 is a side elevation of a radiator element, of which- Figure 2 is a front elevation. i

Figures 3-5 show modified construction.

As shown in Figures 1-3, each element :is constituted by a convenient number t'ubes a provided with Cooling ribs b: said tubes a establishing communication between an upper colleotor o and a lower collector d.

The tubes a may be substantially straight and arranv'edvertically in pairs, as represented in`` *igures l, 2, 3 and ll, or' they may 'be circular, as indicated diagrammatically in Figure 5; and in the'lat'ter case, they the circulation in the other will be arranged one within another in concentric relation. i

The assembling is done' inthe following` manner:

In the upper tank o of the radiator is secured by any suitable means, for instance by screwing, a Vertical union e' (Figure 1) which, lin `the example illustrated in the drawing, receives the upper 'junction pipe e of the element; z i

The tubes a terminate at the bottoni end in a second junction pipe f which is connected to the bottom c'ollector. d either.e by means of a union similar to the union e' at;-

tached to the tank 0, or by` means of aA feeder g as shown in Figure '1.

` The connectlon to the upper and bottom tanks may -be varied as desiredv and it is possible to use either the union or the feeder for any one of, or for both, the tanks o, (Z.

i i/Vhatever the connection utiliaed-whether by feeder or uniona threaded rod 71, (see lfigure 4;) is provided 'which is disposed longitudinally in the junction pipe f and projects beyond the same at opposite ends,

one .end extendinguinto the feeder and through, an opening` in the end wall thereof and carrying a valve This'valve is locatedwithin the feeder, the free edge of which latter constitutes a seat therefor, so that when saidvalve is disposed against its seat it will shutoff communication between the feeder or union and the pipe f. At the top there is, similarly, a sorewthreaded rod arranged in like manner and carrying a `Valve intercepting, when it is pressed against its seat, any communication between the union e' and the junction. pipe or branch e. The two junct'ion pipes a f and the tubes a are secured together to form one piece which constitutes. one element. These tubes a could be replaced by blades or other equivalent parts such as are used in radiatoi's.

'When the element :is sep'arated from the tanks o and' (Z,jit `will be noticed that the ends of the two rods t project from the same; In connectingl the element to the tanks the twojunction pipes f, e are passed over the'rods lt until their adjacent edges abut against the bearings j on the feeders or unions, at which point there are placed washers forming a oint that can withstand a temperature of 300-4000.

` At the front end of each of the junction pipes e, f is also arranged a washer lc secured by means of a nut Z mounted on the front end of the corresponding rod h, a part of each nut Z projecting into the interior of the junction pipe in order to center the latlPatented May n31, T0212..

ter on the screivthreaded rod 71,. By tightsaid operation, to rcplaee the said eleinentby ening` up the nuts an absolutely tight joint of the Whole is ensured. On the front end of the screwthreaded rod ft and projecting` into a smooth recess in the nut is also screwed a look nut m closed at one end and engaging the terminal of said rod which is made square for nianipulating the rod. The rear ends of the rods are threaded through the previously mentioned openings in the end walls of. the eeders or unions and are likervise' 'fitted With lock nuts which are similar to those just described.

The valres having` been suitably moved from their respective seats, and the apparatus assembled as described, it Will be understood that water will circulate through the element and become cooled by heat dispersion 'from the ribs.

In case of a leak occurring, and it :is desired whilst traveling to cut out the damaged element, it is necessary only to unscrew the lock nuts m and to turn by means of a suitable spanner the screwthreaded rods 71, so as to shut the valves f/ down on their seats. The turning of the rods 7a/ is rendered possible as they are supported adjacent their ends in the openings in the nuts Z and the teeders or unions. As soon as the valves z' are in contact With their seats, the element is cut out, and the leak stopped.

On arriving at the destination, or When the chaufteur has time to spare, he can detach the nuts Z and remove the da-maged element and. substitute another. I-Ie then puts back the nuts Z and turns the screw threaded rods h so as to effect the opening` of the valves z' to give the desired flow of the water, and finally secures the whole by means of the lock-nuts m..

In certain cases, When the radiator is ot a limited width, the element could be arranged las shown in Figure 3, so as to give it nevertheless the desircd depth, using' bends p as junction pipes for some of the tubes.

In the case ot circular tubes ot the type represented in Figure 5 the assembling` would still be done by means of screwtln'eaded rods h. In these conditions, the hot and cold Water tanks would be connected to a central feeder x divided into two parts by a central partition m'. Whilst still adhering` to the described method of assembling` the component parts of the element or unit, it is possible to eliminate the valves, which of course removes the possibility of regulating the flow.

The advantages of the use, of the radiator element-s according to the present invention are very great, and the chie'f ones may be summed up as follows:

In case of a leak occurring in the, Cooling blockl7 of a radiator, it is suiiicient to close the regulator valve of the damaged element and then continue the journey, or after the a spare one, and to re-open the r ';ulalor, this operation taking` but a :lew minutes. rlChis )ractically eliminates lealtanje troubles.

In Winter, or in cold countries, the regulators ot each element can be slightly closed .in order to obtain less c'.li1r` and thus avoid lireezing; this makes it possible, to ohtain a variable circnlation.

In Winter one or more elements could he cut out completely by closing their regulators.

In very hot Weather, all the regulators can be opened, or the elements replaced by elements With a larger radiatino' surliace. This makes it possible to obtain a variahlc radiating` surface.

Exaniination and cleanino` are tacilitated. Having now particularly deserihed and ascertained the nature of my said invention and in What manner the same is to he per- 'formed, I declaie that what I. i'laim is 2--- l.
