RADIATOR.

Application led September 25, 1917. Serial No. 193,079.

To all whom z't' may concern.'

Be it known that I, WILLIAM SPARKS,

a citizen of the United Sta-tes, and resident of Jackson, in the county of Jackson, in the State of Michigan, have invented new and useful Improvements in Radiators, of'

which the following, taken in connection with lthe accompanying drawings, is a full, clear, and exact description.

This invention relates to radiators of the type particularly designed for use in the cooling of internal combustion engines in which the water circul ating tubes are separated by a spacer so fashioned and arranged in conjunction with the water tubes as to provide a cellular structure.

The object of the invention is to provide a radiator of the above type of increased efiiciency in cooling a circulating fluid, and preferably this is etl'ected by providing the spacer with a multiplicity or plurality of perforations or openings permitting communication between adjacent cellular units of the radiator structure, and by permitting direct contact of the air passing through the cellular units with substantially the entire exterior surface of the water tubes.

Other objects and advantages will appear from the following description, taken in connection with the accompanying drawin?, in whichigure 1 is a front View, partially 11i sectic n of a portion of a radiator illustrative of the invention herein.

Figure 2 is a horizontal section through a portion of such a radiator.

Figure 3 is a perspective view of a portion of the spacer.

The radiator shown comprises a series of vertically arranged water tubes -1 of corrugated form, each corrugation at the vertical marginal edges of the tube in this specific illustration constituting three sides of 'a hexagonal cell.

The upper and lower ends of the tubular cells may be connected in the usual manner t0 upper and lower headers or tanks, respectively, (not shown) in any suitable or well known manner, not necessary to herein illustrate or further describe.

Each water tube 1 is separated from the adjacent water tube or tubes by a spacer -2, likewise, in this specific il ustration, of corrugated form, and each corrugation at the vertical marginal edges of the spacer in the opposite direction so that these loops constituting three sides of a hexa onal cell, so that when the spacer is place vbetween two adjacent water tubes two verticall disposed rows of hexagonal cells are forme one-half of each cell of each row being above or below, or both above and below, one-half a cell of the adjacent vertical row of cells. i

Theintermediate portion of the spacer and the intermediate portions of the water tubes need not be corrugated with that exactness used in shaping the marginal edges of both the spacer and the water tubes, as the attachment of the intermediate portion of the spacer to the intermediate portions of the water tubes is not necessary, and in ractice is not generally effected.

he marginal portions of the water tubes and the spacer which lie in contact, in this illustration in substantially vertical planes, may be secured together in any suitable manner, as by solder or the like, to constitute a unitary cellular structure.

The spacer, as best shown in Figure 3, is provided at each edge within the marginalA portions -3- that are shaped with exactness, with oppositely offset loops 4- and -5-, respectively. The loops -K-lare slit at opposite sides from a depressed portion of a corrugation 'and are then offset in the opposite direction from the portion of the corrugation from which slit, while the loops -5- are slit at opposite sides from a raised portion of the corrugation and are oifset oo -4-- and '5- extend within corrugations of different water tubes, the loop 4 extending from one side yof the spacer -2 while the loop -5- extends from the opposite side of the spacer.

The portion of the spacer intermediate the loops 4 and -5- is provided with a multiplicity of perforations or openings t5- suiiicient in number to materially interrupt the continuity of the spacer member 100 and to permit free passage of the yair from one cellular unit in the completed radiator structure to adjacent cellular units. Further, these openings, as well as the openings provided by the loops -4- and -5-, per- 105 mit direct contact of air passing through the cells with the portions of the water tubes with which the Spacer member ordinarily lies in contact. By forming the spacer member with a multiplicity of openings, permit- 11o tin free passage of air between the adjacent cel ular units of the structure, the eiiiciency of the radiator in cooling the circulating fluid is materially increased. Although I have shown and described one particular construction of radiator and one particular form and arrangement of the ce1- Jlular structure, I donot desire to limit myself to the same, as the invention herein is adapted for application to many and various forms of radiators irrespective of the exact form and arrangement of the cells7 and Ido not desire to limit myself to the exact form of spacer member here shown,' or to the shape or arrangement of the perforations or openings therein, as many changes may be made in each and all oi' the same without departing from the spirit of this invention as set forth in the appended claims.

What I claim is 1. A radiator comprising a plurality of water tubes, each tube formed of a pair of strips of metal bent into similar tortuous form and shape, and nested together, and havin their edges o-set and in Contact, and tieir central portions spaced apart, a spacer between each adjacent pair of water tubes, said spacer formed of a strip of metal having its opposite edge portions accurately shaped to the same form and outlinev as the edge of the strip constituting. the water tubes, said spacer forming with said two adjacent water tubes two vertical over-lapping rows of cells, the said spacer constituting a symmetrical one-half ofthe wall of each cell, and pairs of loops formed in connection with the spacer and positioned adjacent the respective accurate shaped edge portions thereof, and extending in opposite directions from the said spacer in the said rows of cells and spaced from the. walls of the water tubes.

2. A radiator comprising a pluralit of water tubes, each tube formed of a pair of `and their central portions spaced apart, a

spacer between each'adjacent pair of water tubes, said spacer formed of a strip of metal having its opposite edge portions accurately shaped to the same form and outline'as the edge of the strip constituting the water tubes, said spacer forming with twol said adjacent water tubes two vertical over-lapping rows of cells, the said spacer constituting a symmetrical one-half of the wall of each cell, and airs of loops formed in connection with tlie spacer and positioned adjacent the respective accurate shaped edge portions thereof, and extending in opposite directions from the said spacer in the said rows of cells and spaced from the walls of the water tubes, the intermediate portion ot' said spacer between said loops provided with a multiplicity of perforations.

3. In a radiator, a pair of tortuous water tubesl` a spacer formed of a single strip ot" material having its opposite edge portions accurately shaped to the same form and outline as the water tubes, said spacer' positioned between and forming with said water tubes two vertical over-lapping rows of cells and pairs of loops formed in connection with the spacer and positioned adjacent the respective accurate shaped edge portions and extending in opposite directions from the spacer into said rows of cells and spaced from the walls of the water tubes, and the intermediate portion of said spacer between said loops being provided with a multiplicity of perforations. y

In witness whereof I have hereunto set my hand this 18 day of Sept. 1917.
