RADIATOR AND METHOD OF FORMING THE SAME.

Application filed March 9, 1926. Serial mfsano.

This invention relates to radiators and more especially to the method and means for connecting the terminals of the water passages of the radiator within the water supply tank or to the outlet from the radiator. The invention is applicable, for example, to radiators of the general type described in my copending application. Serial No. 641,850, filed May 28, 1923, although in its broader aspects not limited to this particular type of radiator.-

One of the objects of the invention is to provide a simple, easy method of securing a tank to the core of a radiator of this type, whereby each water conduit will be connected to the tank without danger of closing or stoppage of any of the water conduits.

Another object of the invention is to provide a method of securing a tank to the core of a radiator whereby each conduit is connected to the tank without solder, it being necessary to solderonly around the outer edges of the tank and core.

Another object of the invention is to provide a simple method of securing a tank to a radiator core in which each Water con.

duit is considerably strengthened adjacent tot-he tank and the whole structure thereby rendered more rigid and firm.

Another object of the invention is to provide a radiator in which the upper and lower header sheets are held between the core and extra elements adapted to telescope with the water tubes of the core whereby the strength of the connection is dependent upon the strength of the extra or core element rather than upon a solder connection.

Other objects of the invention will be apparent as the description proceeds.

One embodiment of the invention has been illustrated in the accompanying drawings,.in which Fig. 1 is a side elevation partly in section showing an upper tank wall, the parts in position before pressing together to form the rigid connection; Fig. 2 is a view corresponding to Fig. 1, but with the parts pressed securely together; Fig. 3 is an elevational View partly in section of the connection between the lower tank and the core.. 7 p

For purposes of illustration, I have shown in the drawings a radiator core 10 comprising a plurality of superposed fins or elements 11 having integral tubular projections 12 telescoped together to form water conduit-s 13from top to bottom of the radiator core.

The upperwater tank or header 14 has a I bottom or header sheet 15 which is perforated in a plurality of places asat 16 to register with the water conduits 13 in the core.

An element 17 preferably identical with duits 13 of the core. The element 17 is thenplaced over the bottom or header sheet 15 so that the projections 18 protrude through the holes 16 in the header 15 and enter the water conduits 13in the core. The element 17 is then pressed firmly down as far as possible, forcing the projections 18 into the conduits 13, where they are held by friction securing the header sheet 15 firmly between the strip 17 and the uppermost element 11 of the core 10. A water. tight connection is formed thereby between the telescoping proections 18 and the water conduits 13 so that the conduits 13 are, so to speak, extended up throughthe strip 17 and the holes 16 in the header sheet are closed and frictionally sealed by projections 18 passing therethrough. If care is taken to provide the holes 16 of the proper diameter to fit snugly about the projections 18, the connection between the core and the tank may be made water tight without soldering, but to guard against the possibility of evenness in the projections 18 or size of the holes 16, solder may be applied to the outer edges of the header sheet 15 and the upper core element 11, as indicated at 19.

The lower'tank 20 is secured to the core 10 m a similar manner as to the upper tank. The header sheet 21 is provided with holes 22 adapted to register with the water conduits 13 and receive the ends of the proections 12 on the lowermost element 11. The strip or extra element 23 has projections 24 thereon adapted to telescope with the projections 12 of the lowermost element 11 and is adapted to fit inside the tank 20.

The core 10 is set upon the bottom tank 20 with the pro'e'ctions 12 of the lowermost element protru ing through the holes 22.

a leak due to un- The strip 23 is then pressed up against the header sheet 21 as. far as possible so that the projections 24 telescope with and frictionally engage the projections 12 of the lowermost element of the core. tight connection is thereby made between the projections 12 of the lowermosttstrip and the projections 24 of the strip 23, and the holes 22 are sealed by the projections 12 of the lowermostelement of the core. This provides a' liquidtight connection between the tank and the core but'as in the case of the upper tank solder is applied around the edge of the lowermost element 11 of the core and the header sheet 21 as at to remove all possibility of leakage.

The projections24 on the strip 23 may be shorter than the projections 12 on the ele- .ments' 11 so as not to extend too far down radiator having water conduits therein to a into the tank 20, or, if desired, certain of the,conduits, as 26, may be cut oil just below the strip 23 to rovide 'an outlet for any steam which mig t collect in the lower tank beneath the strip 23, as described in my issued Patent, No. 1,527,736, granted February 24, 1925.

With this construction, not only is a liquid tight connection provided, but at the same time the ends of the water conduits and the header connections are greatly strengthened as the extra thickness of the projections of the

strips

17 and 23 is added'to that of the water conduits, making substantially double walled projections just below and above the upper and lower headers, as shown for example in the sectional portions of Figs. 2 an 3. The ends of the water conduits merely frictionally engage the tubular projections on the stri s, no solder being used, and hence danger o clogging or closing any of the conduits is eliminated. Y

It will be understood that although I have illustrated one type of radiator core the invention in its broader aspects may be used with any radiator core having a plurality of straight parallel inlets or outlets at anend thereof, and I do not therefore desire to limit my invention to the particular embodiment shown in the drawings but to interpret the invention broadly within the scope ofthe appended claims.
