To all whom it may concern:

Be it known teat I, D MoRA LIVINGSTON, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Cooler or Similar Apparatus, of which the following is a full, clear, and exact description.

The invention is more particularly intended for the coolers of motor-vehicles propelled by explosive-engines.

' The resent invention consists in a cooler having lapped oints at the side edgesformed by means of return-bent or inwardly-projecting portions formed along the o posite edges of one plate or wall and outwardlyrojecting plain portions on the two side e ges of the corn anion plate or wall of the conduit throu h W 'ch the fluid to be cooled passes. In or or that the hooked edge ortions may be formed, I produce slits at t e angles, as

, will be fully explained hereinafter.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an elevation, partly in 'section, of a cooler embodying my present invention. Fig. 2 is an enlarged cross-section taken on the line 2 2 of Fig. 1. Fig. 3 represents an enlarged detail section taken on the line 3 3 of Fig. 1. Fig. 4 represents an enlarged detail section taken on the line 4 4 of Fig. 1.-

Fig. 5 is a fragmentary pers ective view showing a pair of corrugated plhtes prior to the bending of the hooked portions. Fig. 6 is a perspective view illustrating the embodiment of my invention in aform of cooler composed of complete tube instead of corrugated plates. Fig. 7 is,a longitudinal sectional view through a cooler of the form shown in Fig. 6. Fig. 8 is a sectional elevation illustrating the embodiment of my invention in a cooler in which the conduits are arran ed to produce a diamond design-that is, wit the bends of the conduit diagonal to the vertical and horizontal. Fig. 9'is an enlarged cross-section taken on the line 9 9'of Fig. 8, and Fig. 10 is a fragmentary detail view of one of the walls shown in Figs. 8 and 9.

In the form shown in Figs. 1 to 5 the conduits are corrugated so as to produce three sides of a square, said sides ran ing alternately vertically and horizonta ly. Each conduit is formed of a pair of plates A B,

-tions of which are expanded, as usual.

I having, respectively, return bends or hooks a and outwardly-projecting plain portions 5. The respective plates are effect at the side edges in such a way as to bringadj scent conduits into close contact at the side edges; but as the special manner of offsetting and forming the side edges does not form part of the present invention aside from the fact that the hooked portions are on both edges of one plate and the plain portions on both edges of the other late the descriptionwill be confined to t e manner of forming the returnbends. Thus, referring more particularly to Fig. 5, it will be seen that the plates'A and B have been corrugated and that the former is wider than the latter, the sideedges rojecting beyond the plate B. In order t at the projecting edges of the plate may be returned to reduce the inwardly-projecting hooks b, I rorm slits a at the an les of the corrugations, whereby the three sides marked a? in this figure may be independently bent to the form shown in Figs. 2, 3, and. 4.

In the form shown in Figs. 6 and 7 the cooler is formed of the tubes 0, theend por- In my invention certainsides of the expanded ends of the tubes are projected, as at c, Fig. 7, whereby they may be bent inwardly, as at c, to engage an outwardly-projecting plain edge portion 0 of an adjacent tube. It will be seen that each short run or section of a'conduit O is formed by the adjacent walls of adjacent tubes, and, as shown best in Fig. 7, one of said walls is formed with hooks c on both ends, while the opposite walls of the conduit have plain edges 0 on both ends, which are enga ed by said hooks.

. In the form shown in Figg. 8, 9, and 10 the side edges of the plates D are formed, re spectively, with hooks d and plainportions d in substantially the same manner as described in the forms shown in Figs. 1 to 5, except that the flanging of the side edges is roduced on diagonal lines, as indicated at d in Fig. 8, the flanged edge being slitted at the angles, as at (i In all the forms it will be observed that the conduits have bends forming circuitous passages for the fluid to be cooled.

Having thus described my invention, I claim as new and desire to secure by Letters Patent.
