To all 'whom it may concern:

Be it known that I, Jorrit M. Ennemis;

a citizen of the United States, residing at Buffalo,` in the county ot Erie and State 6 of New York, have invented new and useful 10 the water of a gas engine and has for its object the production of such a radiator which is simple and inexpensive in construe tion, efficient in operation and exceedingly strong so that the same is capable ot with- 16 standing any unusual strains to .which the same may be subjectedwhile in use.

In the accompanying drawings: Figure 1 is a front elevation, partly in section, of

theradiator embodying my invention. 20 2 is a horizontal section taken on line 2--2 Fig. 1. Fig. 'is a fragmentary vertical section taken on the correspondingly numbered line in Fig. 2. Fignd is a fragmentary perspective View of one of the radiating 26 members of the core containing my improvements. Fig. 5 isa plan view ot part of a blank from which the radiating member is constructed. Fi 6 and 7 are fragmentary perspective views' of the Water tube Similar characters of reference refer to like parts in the several figures.

In its general construction my improved radiator comprises a plurality or upright i5 water tubes or passagesl which are arranged side by side and are of tortuous or zigzagged form, and a plurality of horizontal air passages 4, arranged between the several water tubes or passages. In the complete v4l) radiator the upper and lower ends ot the water tubes are connected with the conduits or boxes forming part of the circulating system of the gas engine so that the hot water from the engine as it passes through 46 these water tubes is cooled bythe currents of air passing horizontally through the air assiiges.

Each of the water tubes is constructed of at its opposite edges and on oneside of this wall and on the turns 7 of alternating corrugations thereof which oisets project laterallyroin the concave sides of the respective corrugations. The turns of the remaining corrugations are not provided with oH-sets but are continuous from edge to edge of this tube strip or wall, thereby forming straight or continuous valleys or bottoms 8 on the opposite side of this strip. The two Awalls of each group are assembled so that they are parallel and engage each other at their opposite edges, thereby forming a water passage between the same. When thus assembled the convex sides of the con tinuous turns of the corrugations of one wall engage the concave sides ofthe osets of the turns of the other companion wall, thereby forming closed joints between the walls at their opposite edges and leaving a space between the central parts of these walls which constitute the water passage.

The plurality of air passages 2 arranged between two water tubes are formed, partly by the two opposing walls of these tubes and partly by a radiating member arranged between these two tube walls. In its preferred forni this radiating member comprises a plurality of parallel transverse plates 9 arranged in longitudinal rows between tlie opposing walls of two tubes and each oit these plates engaging its opposite edges with the continuous bottoms 8 ot the corresponding corrugations in the opposing sides oi said walls. a plurality of longitudinal plates i0 arranged lengthwise in a row between said walls and alternatingwith' -said transverse plates, and a pluralityv of coupling straps il which are arranged par allel with said transverse plates and each of 9i which is connected at its inner side. edge with one of the side edges of the adjacent longitudinal plate. while its outer side edge 'is connected with the side edge of one of the adjacent transverse plates. In the pre- 100 two outer walls orstrips 5 of sheet metal;

89 each of which is .bent or corrugated into" have their inner edges connected with op 10i zigaagged form for producing a succession posite side 'edges otono of the longitudinal of summits and valleys on each side of the plates. while the outer edges of these straps strip? which summits and valleys alternate are connected with the diagonally opposite outer or side edges of the adjacent transvvij-iwith each other. Each of these water tube, Wwalls or strips is provided with ofi-sets 6. verse plates. The transverse and longitudi-ll nal plates of each radiatingmember are of the same width as the walls ot the water tubes and the front and rear ends or e ges of the same are flush. The coupling st ps are however, of less width than said plates and are arranged at a distance from the ends or end edges of said plates, thereby causing the radiating members to present the appearance olf single lines both lengthwise and crosswise at the front and rear side of the radiator core. The transverse plates of the radiating members are provided with openings l2 which are preferably formed on the central parts thereof, which serves to reduce the weight ofthe saine and also to provide inter-communication between adjacent air tubes so as to permit a free circulation of air both vertically and horizontally through the air tubes or passages.

Each ot' the radiating members is preferably constructed from a sheet of metal which is lirst stamped out in the form o'l'l a blank as shown in Fig. 5 and then bent or folded into the form shown in Figs. l, 3 and 4.

The two water tube walls on opposite sides of' each radiating member are preterably connected with each other at the upper and lower ends of the companion radiating member and those two walls are preferably 'formed from a single strip ol sheet metal which may be doubled or folded upon itselt1 midway ci its length and al' the end ot' the companion radiating member. as shown at 13 in Fig. l. while the opposite ends of this strip forming these two tube walls may be interlocked with each other by means of a lock seam or similar joint., as shown at 14 in the same figure.

A ra'diator unit is thus formed in which the two opposing walls of adjacent water tubes form the outer members. while the radiating element between the same forms the intermediate member. ln the manufacture of the radiator a plurality of such units are assembled side by side so that the outer walls ot each unit interlock with the water tube walls of adjacent units aft-er which the core thus formed by the plurality of units is dipped in solder so as to Permanently connect the front and rear edges of each pair ot' water tube walls and render the same water tight or leak proof and at the same time cause the solder to unite the radiating members with the water tube walls so as to hold the same firmly against displacement relatively to each other.-

lnasmuch as theQ lateral edges of the transverse plates and coupling stra-ps engage with the bottoms of the continuous turns of lthe corrugations of the water tube walls. these parts are accurately, easily and reliably centered relatively to each other, and owing to the', increased soldering sur$1 epesses face which is by this means obtained between .the lateral or side edges vof these transverse plates and coupling straps and the continuous bottoms of the corrugations of the water tube walls, a much stronger and durable connection is obtained between the same which increases the rigidity '0f the radiator core and enables the same to withstand more effectively the shocks or strains to which the same is liable to be subjected while in use.- l

In practice the outer walls of the radiator tubes are constructed of copper -or of brass or similar metal which vis not liable to corrode by reason of the action of the water which passes through the same and thus renders the l radiator water tight. The radiatingmembers may, however, be constructed of terne or other inferior metal which is of lowercost than the water tube walls inasmuch as the same is not exposed Ato the corroding action of water, but still vpossesses sufhcient heat conducting capacity to eiiiclently carry oli the heat from the water tube walls to the adjacent atmosphere. The radiator core can ,therefore by ithis means be produced at much less cost and still provide sufficient radiating capacity for all practical purposes.
