RADIATOR.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application led September 23. 1918. Serial No. 255.282.

To all whom t may concern:

Be it known that I, FRANK WV. MERRITT, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Radiators, of which I do hereby declare the following to be a specification.

My invention relates to radiators and has for its object the provision of a radiator of improved structure, of the water circulation type, for automobiles, or other purposes. One of the objects of my invention is to provide a removable unit or section of improved structure, adapted in coperation with similar units or sections to form part of a sectional radiation column embodied in such radiator. With these and other obconsists of the structures, combinations and arrangements of parts hereinafter described and claimed.

In the drawings, Figure 1 is a top plan view of one of the hereinafter described units or sections embodied in my said invention. Fig. 2 is a'section of two of said units on the line A-B of Fig. l. Fig. 3 is a section of two of said units on the line C-D of Fig. l. Fig. 4 is a plan view of a hereinafter described baille plate forming part of one of said units. Fig. 5 is an end view of said baille plate. Fig. 6 is a front elevation of a radiator' embodying my invention, partly in section on said line C-D of Fig. 1, and partly broken away.

In the drawings, l is a header member or upper circulation chamber; 2 is a base member or lower circulation chamber; 3, 3 are side walls secured at their upper ends to said header and at their lower ends to said base; said side walls preferably containing circulation chambers 3a adapted to communicate with the circulation chambers in said header and base, respectively. If desired the circulation chambers in said side walls may be omitted. Extending between said header and base are any suitable number of sectional radiation columns, each in cluding a series of removable radiation units, each of which units consists of a broad thin hollow chamber 4 open at one end and a baffle plate 5 of slightly less area than said chamber and adapted to extend thereinto. Said baille plate is spaced from the walls of said chamber and has formed on one of its-ends a shoulder 5a adapted to close the open end of said chamber 4; it also preferably has formed on said shoulder a crown portion 5b adapted to extend across the adjacent end wall of said chamber 4.

Gn the outer surface of one of the broad walls of each such unit 4 is formed a taper bored or female nipple 4a, the bore of which communicates with the interior of said chamber at one side of said baille plate. The other of the broad walls of each such unit 4 has formed thereon an apertured externally tapered, or male nipple 4b, the aperture in which is adapted to communicate with said chamber 4 at one side of said baille plate. The taper bored nipple of any of said units is adapted to engage the externally tapered nipple of another of such units in building a column of such units. Said base or lower circulation chamber has formed in its upper wall an aperture 2a adapted to engage the lower terminal nipple of a column of such units. Said header has formed in its floor a threaded aperture adapted to engage an apertured adjustable nipple 6 which is adapted at one end to engage the upper terminal nipple of a column of said units. Mounted on said adjustable nipple intermediate of the ends thereof is a jam nut 6a adapted to be set against the lower face of the iioor of said header after said adjustable nipple has been screwed home. Said adjustable nipple is employed to press the units of said column into close engagement; it will be noted that there may be slight variances between the heights of the columns which will be compensated by the adjustable nipples, thus preventing leakage from the shorter columns. Said adjustable nipple may be retracted by first retracting the jam nut and then unscrewing the nipple by means of any suitable instrument introduced through an aperture la formed in the upper wall of said header. If desired the aperture in any such adjustable nipple may be plugged by any suitable plug (not shown), which may be introduced through said aperture la, thus cutting off the circulation be tween the corresponding column and said header. If desired to remove one of the units from said Column, the corresponding adjustable nipple is first retracted and the column may then be pried apart on each side of the unit to be removed; the desired unit may then be removed and another substituted and the adjustable .nipple may then -be restored to operative position. To avoid danger of collapsing the walls of said chamber 4 by the' compression exerted by said adjustable nipple, there is formed on each side of said bafiie plate one or more lugs 5 adapted to narrowly limit any convergence of the upper wall of the unit toward the vlower wall thereof, and to divide the collapsing strains between said upper and lower walls. Said base is preferably apertured in its floor as at 2b in alinement with said nipples, and, if desired, the lower end of any of said columns may be plugged by any suitable plug (not shown), introduced through the corresponding aperture 2", whereby circulation between such column and such base chamber may be cut off. Said apertures 1a and 2 are normally closed by any suitable plugs, as lb and 2L14 respectively.

Said radiator may be connected with the water jacket of a gas engine (not shown) or with any suitable reservoir by means of ports -1c and 2 formed in said header and base respectively and shown in broken lines.

Saidchambers 4 and baffle plates 5 are preferably formed separately by die casting. In order to secure a tight fit between the shoulder 5a of said baffie plate and the adjoining walls of the chamber 4, a thin shallow flange 5d is cast on said shoulder, which iange is crushed or spun when said shoulder is forced into said chamber, the material of said flange thus effectually calking the joint. lf desired, said flange may be formed upon the inner face of the walls of said chamber adjacent to said shoulder instead of upon said shoulder.

It is obvious that my invention may be modied in various details within the scope and spirit of certain of my claims.

1. In a radiator, the combination of two circulation chambers spaced from each other, a series of circulation units interposed between said chambers, one of the terminal units of said series engaging and communicating with one of said chambers, an adjustable nipple mounted in the other of said chambers and engaging the opposite terminal of said series, said series and adjustable nipple being adapted to conduct liquid from one of said chambers to the other, each of said units being removably engaged with another of said units.

2. A radiation unit comprising .a broad thin hollow chamber open at one end, said chamber having a taper bored nipple formed on the outer face of one of its broad walls, the bore of said nipple extending through said wall, said chamber having an externally tapered nipple formed on the outer face of its opposite broad wall, said externally tapered nipple having a central aperture formed therein communicating with said chamber, a baiiie plate extending into said chamber, said baffle plate being spaced from the broad wallsand from one of the narrow walls of said chamber, said baffle plate having a shoulder formed thereon adapted to close the open end of said chamber.

3. A baffle plate comprising a thin broad body portion, a shoulder portion at one end of said body portion and a thin shallow flange encircling said shoulder portion intermediate of its ends and in the direction of its greatest diameter.

4. A baiiie plate comprising al thin broad body portion, a shoulder portion at one end of said body portion and extending from four sides thereof, and a thin shallow flange encircling said shoulder in the direction of its greater diameter, said flange 'being positioned inwardly of the outer end of said shoulder.

5. A baiiie plate comprising a thin broad body portion, a shoulder portion at one end of said body portion, and spacing lugs found upon the broad sides of said body portion.

6. A radiator unit comprising a broad thin chamber open at one end, a baille plate extending into said chamber and spaced from the broad sides thereof, said baflie plate having a shoulder formed thereon at one end adapted to approximately close said open end of said chamber, Vsaidy shoulder having a thin shallow yielding iange formed thereon constituting a calking element be* tween said shoulder and the adjacent walls of said chamber, each of the broad walls of said chamber having a port formed therein.

7. A radiator comprising two circulation chambers spaced from each other, a series of radiation units interposed between said chambers, each of said units being removably engaged with another of said series,

said series being adapted to conduct liquid,

a tubular adjustable nipple adapted to com` municate at one end with one of the terminal ports of said'series and at the opposite end with one of said chambers, said nipple being adapted at one end to bear against said one of said chambers and at its opposite end to bear against the adjacent unit of said series, means for adjusting said nipple wherebyV said nipple is caused to thrust said units into close engagementwith each other, each of said units having a bafiie plate therein spaced from its broad walls, each of said baffle plates having transversely directed lugs formed thereon adapted to prevent the crushing of the broad walls of the unit by the compression strain of said adjustablenipple, the opposite end of said series being adapted to bear upon and' communicate with the other of said circulation chambers.

8. 1n a radiator, two circulation chambers spaced from each other, side walls extending from one to the other of said chambers, aV

lili

series of liquid conducting units interposed between said chambers, each of said units being removably engaged with another of said units, said series communicating at one end with one of said chambers, a tubular adjustable nipple interposed between the opposite end of said series and the other oi' said chambers, and a jam nut mounted upon said adjustable nipple, the construction be ing such that liquid may liow through said series and nipple from one to the other of said chambers.

9. In a radiator, the combination of an upper and lower chamber spaced from each other; side walls extending from the upper to the lower chamber and containing liquid conducting chambers communicating with said upper and lower chambers; a liquid conducting column comprising a plurality of liquid conducting units containing ballie plates interposed between said upper and lower chambers, each of said units being removably engaged with another of said units, said column being shorter than the space between said upper and lower chambers; a tubular adjustable nipple engaging said Column at one end and enga-ging one of said Chambers at the opposite end, said nipple being' adapted to bear against the adjacent one of said units and to force said units into close relation to each other, the other end of said column being adapted to Communicate with the 4opposite chamber.
