' AUTOMOBILE RADIA'roR.

Application led April 17, 1918, Serial No. 229,171. Renewed January 17, 1923.

To all 'whom t may concern:

Be it known that I, ALBERT KLELL, a citizen of thev United States, residing at West Park, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements inl Automobile Radiators, of which the following is a specilication.

This invention relates to an improvement in an automobile radiator, and the object is to provide a radiator having a plural number of water-.circulating sections or units which may be removed separately merely by unscrewing two nuts exposed at the front of the radiator body. Each unit consists of a column of disk cells of square outline, and each cell is divided into two compartments by a perforated diaphragm, thus causing the water to owin a thin stream from the center vto the edge of each cell and back to the center and thence into the neXt cell over a similar circuitous course and so on through the column.

' In the accompanying drawings, Fig. 1 is a front view of a radiator constructed according to my invention, but showing only one-half of its full complement of watercirculating units removed, and Fig. 2 is a sectional view of the top and bottom portions of a radiator body with the water-circulating units removed, and Fig. 3 is a sectional view of one of the units, but-shown shortened by omission ofcentral cells. Fig. 4 is a side View of the radiator, partly in section, showing the units fastened in place. Fig. 5 is an enlarged sectional detail of one cell showing the walls and diaphragm separated. Fig. 6 is a plan View of a cell diaphragm.

The radiator comprises an open frame consisting of two water-distributing compartments 2 and 3 whichsare rlgidly unlted i together in spaced relation by narrow side walls forming a frame, in a sense, within which the radiator units are adapted to be removably secured. The bottom compartment 2 has a water outlet connection 5 at its rear, and top compartment 3 is rovided with a water intake connection 6, a so at lts rear. Each compartment 2 and 3 hasy a channeled-or hollow offset 7 at its rear extending inwardly which provides a vertical seat or wall 8 transversely of the radiator, and the respective offsets project toward each other and rovide a recess in the front face of the ra iator adapted to receive av series of water-circulating and cooling sections or .units 12. Thus,\the headsvl() and 1'1` at opposite ends of each water-circulating un1t 12 may be seated upon the retired wall 8 and a watertight joint made thereat by placing, suitable rubber gaskets 13 between the meeting faces of the assembled parts. The means for clamping each unit in place, consists of a bolt .14 extending through a tube 15 within each odset 7, and the bolt is either screwed or seated in place and eX- tends forward beyond the front face of the radiator; In this way, each unit may be easily slipped into place from the front and also easily removed. The heads or ends of each unit are hollow and each has a central tube 17 extending therethrough from front to rear, and a recess or pocketv 18 is formed in the front face of each' head to receive the nut 16.

When assembled, the hollow interior of each unit head and the compartments 2 and 3 are open to each other for a"free vflow of water, and a pair of nipples 19 is provided in wall 8 adjacent each bolt 14, each nipple having a flange secured to the inner side of the wall 8 and being projected forwardly to enter suitable openings in the rear fiat wall of .each head, and which openings necessarily correspond in position to that of the nipples.

s Each water-circulatingunit 12 is a builtup or composite structure, consisting of the hollowheads or ends 10 andll built into a column of disk cells 21, having short necks sleeved and united together. Each cell comprises two dished parts 22A and 23 of concavo-convex formation seamed together, and I insert a thin metal plate 24 centrally between the said parts. This platehas a row of perforations 25 in its border and the body of the plate is also provided with rounded projections 26 struck up in opposite directions on radial lines, and these projections space the outer walls or sections 22 and 23 in definite distances apart and also revent complete collapse thereof. Each cell 1s made of thin metal, and the diaphragm 24 having projections as described 4is of advantage in reinforcing the cell. The cell parts 22 and 23 have each a short neck, 27, whereby a sleeved union may be made with an adjacent disk cell of similar construction, in this way building up a column of such disk cells through which the water is-adapted to circulate in a circuitous course beginning at the vcell. i

ycenter lof each disk cell and passing to the outer edge thereof, thence through the perorations in the diaphragm and back throu hythe upper chamber to the center of the yce l where communication is established with the" next adjacent orisuperposed disk i The water circulat'ingunit. as thus constructed is strong durable, and alsol suliiciently flexible to withstand any ,expansion or contraction-to which itfmay be subjected, and itis-falso Well adapted to withstand the shocks and vibrations met with when used in anv automobile radiator. I

have shown ythe disk cells as square so that a "solid'bankof ksuch cells may be placed in close juxtaposition-w'ithin theo yen frame of the radiator, and when so p aced'each:` disk cell separated slightly from the next and/ air aces are provided from front-to rear of the radiator and all of the cell surfaces are exposed to the cooling influence'of Y thev air passing through the radiator.

What4 I claim is:

1. 'A radiator comprising separate water compartments at its top and at its bottom having sheet metal 'walls oii'set inwardly to providetransverse recesses and vertical seats facing the `front side of the radiator and water passages therein at the rear side of said recesses and seats, said vertical seats having a` series of elongated depressions therein and a plurality of spaced openings at kthe base of each of said depressions, in combination with` separate water circulating units having hollow end portions seated in said recesses and provided with openings at their -rear sidesr corresponding in os1ti`on and number to the openings at the ase of each of said depressions, nipple projecting through a pair of said openings in each depression, re-enforcing tubes extending through said oiset Walls rearwardly of said depressions, elongated gaskets seated within said depressions, and clamping bolts extend-` y ing through said reenforcing tubes centrally between eachpair/of openings adapted to securey the units detachably in place.

2. A radiator comprising an openfra'me havingI hollow water compartments at its top and bottom, thev walls thereof being made of sheet-metal and offset 'angularly to provide transverse water passages and vertisaid bolt-openings sealed at their ends to the eoy interior of said transverse water passages yandgaskets seated within and confined at their edges by the border walls of said depressions, in combination with vertical yvvater-circulziting and cooling units having hollow end compartments and openings in therear walls thereof corresponding in poi sition to said water-circulating and bolt openings in said seats, and clamping bolts for each unit extending through said bolt openings. y

Signed at Cleveland, in the county ot Cuyahoga, and State of Ohio, this 1st day of April, 1918.
