RADIATOR.

Patented Mar. 11, 1913.

Application filed April 13, 1912. 7 Serial No. 690,583;

useful Radiator; and I do hereby declare the following to be a full, clear, and exact .descriptionflof the invention, such as will enable others skilled in the art to which it 10 appertainsto make and use the same, reference being I had tothe accompanying drawings; and to the characters of refer ence marked thereon, which form a part of this specification.

@My inventionrelates to radiators of the cellular typecommonly used for cooling 'tlie water which is circulated around the cylinders of automobile engines, but is not restricted to such use-as it may be employed inuany connection for which it may be adapted or appropriate.

iThe object'of my invention is to siu1- plifyandimprove upon the construction of "radiators" of this character, whereby toenhance'theefiiciency and practicability thereof, 'cheapen their cost of construction, and reduce to a minimum the liability'of leak a e.

, A further object of my invention is to build the radiator up from a plurality of units, anyone of'which can be easily re-- moved for the-purpose of repair or substitution without disturbingfltheother units. ...The invention is fully described in the following specification, and while, in its broader aspect ,it.is capable o'f embodi ment in numerous forms,a preferred embodiment thereof isillu drawings, in which, v I I 40 v Figure 1 1s a front elevatlonof a radiator Y'einhodying myinvention. 2 is an err largedfront; edge View of three connected --units thereof. Fig. 3 isa cross-section of such units on the line w, a: in Fig.2. Fig. 4

-is' an enlarged, cross-section, of one of the in-carrying units, Fi .5 is a plan of a blankof the outer mem er of a fin-carrying unit with a portion of the fins struck up,

andFig. 6isa perspective view of the membersof a tin-carrying unit partly removed. Referring to the drawings, 1 designates the cellular structure of a radiator,.and 2 the surrounding carrying frame therefor, which has its upper and lower portions forming the customary receiving-and disher 3 which is preferably strated in the accompanying posed of alternately arranged preferably upstanding units 'a and b of sheet metal structure, the former of which forms merely water circulating passages of flattened or transversely elongated form, while the latter comprise the fin ca'rrying units of the radiator.

Each unit b comprises a flattened or transversely elongated water circulating memformed byfiat tening a sheet metal strip centrally upon ,70 itself withits walls in spaced parallel relation and having its free edges la ping each other preferably at a vertical e ge of the tube, as shown at 4 in Fig. 4e, and soldered or otherwise suitably treated at such lapping edge to seal the same against leakage,

The side walls of the members 3 are continued attheir ends beyond the \ierticalor front and back edges of the members? to provide flanges 5, which are bent at right- :angles outwardly from the-respective walls; and are intende the corresponding flanges 6 of the adjointo lap and be soldered to ing units a, which units are of the same construction as the parts 3 of the units 6, as best shown in Fig. 3, Each unit I) also includes a tin-forming member 7, which is intended to transverselywraparound or encompass the part 3.

The fin --form1'ng. member-7 preferably comprises a blank, which is provided at each side of its longitudinal center with a set of spaced parallel slits 8 extending outwardly from adjacent to said center and to'near theassociated outer edge of the sheet, substantially as shown ii Fig. 5; The slits 8 of each set have short slits 9 extending in the same direction laterally from their ends toadjacen't to the ends'of the slits next in order, with the slits 9 the same'iends of the slits 8' preferably" longitudinally aliaing. This manner ofslitting the blank'provides the center or longitudinal bin-getaor strip 10, the outer parallel edge strips 11, 11, and the parallel transverselyextending bars or strips 12, which latter connect the center and outer strips 10 and 11 intermediate the ends of successive ones of the slits 9. The blank having been slitted in this manner, the fins 13, which are the parts 7 bounded by the slits'8 and 9, are bent outwardly in parallel outstanding'relation, and the two halves or fin carrying portions of the blank are bent toward each othefin opposition to the direction of projection of the fins.

, In the assembling of the members of a unit I), a tube member 3 is inserted between the leaves or halves of a member 7, with one edge of the tube member in contact with the.

hinge-bar or strip 10 of the member 7 The leaves of the member 7 are then drawn. in

close parallel relation to the sides of the tube member, with one edge strip 11 thereof, which is broader than the other, bent around the outer edge of the member 3 and soldered 'or otherwise suitabl secured in lapping relation to the outer side of the other stripll of the member 7, as shown at 14 in Fig. 4;. It is thus apparent that each section or unit 6 comprises fiat tube member 3 and an enveloping fin-forming member 7, Whereas each unlt (1 comprises a single flat tube memher, which, in the present instance, is the same in construction as'a member 3 of a unlt b.

In the assembling of the radiator sections or units, a single unit a is disposed between units 6 of successive pairs so-that the units a, b are arranged in alternate relation. The units are held in properly spaced relation by the fins 13 of the units I), such fins bearing at their outer edges against the adjacent side Xvalls of the unitsva whereby to cooperate with such units and the sides of the tubemembers 3 of the units 12 in the forming of horizontally disposed air circulating cells between the units as shown. The units are held in such relation by a lapping and soldering of the adjacent unit flanges 5 and 6. When any desired number of units have been assembled in this manner the outer face thereof or that exposed in Fig. 2, 1s prefer-- ably dipped into a liquid solder to give the outer side of the radiator an integral ap pearance.

With thisform of radiator it is a very simple matter to remove a section or unit for the purpose of repairing or substitution as it is only necessary to break the soldere connection between the flanges 5 and 6 and the points at the face of the radiator where the sections may be soldered together in the dipping process, thus materially simplifying and quickening the repairing operation over the constructions of radiators commonly used. It will also be apparent with this construction ofradiator that the possibility of leakage is reduced to a minimum, .as the 0 1y seam in the water circulating tubes of the sections or units occurs at the point 4 thereof, or at the edge of the tube members where the edges of the sheets forming the same are lapped.

I Wish it understood thatmy invention is not limited to any specific jconstruction or arrangement'nf the parts except in so far as such limitations are specified --in the claims.
