Tau/ll whmn it may concern:

Be it known that I, FRANK BRIsooE, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Radiators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to radiators, particularly designed as coolers, for use on motorvehicles; and the invention consists in the construction as hereinafter set forth.

In the drawings, Figure 1 is a cross-section throu h the radiator. Fig. 2 is a side elevation t ereof. Fig. 3 is an end elevation, and gig. 4 is a cross-section through one of the My invention relates to. radiators, and more particularly to that type -in which the conduits for the fluid-circulating medium have sleeved thereon radiating disks or fins, which are exposed to contact with transversely-passing air-currents. With this type of radiator it is desirable to have a uniform amount of radiating-surface on the fins for each of the conduits, and to further effect the cooling it is desirable to ex ose the surface of the conduits between the s to the air-currents. To effect the latter result, a staggered arrangement of the conduits is preferable ;but with such an arrangement it Is diflicult to provide radiating fins of equal surface upon said conduits and to arrange themcompactly within the space. There is also an advantage in tying the conduits of adjacent rows together by sleeving thereon a common or gang fin. With my improved construction- I have secured a very compact arrangement of parts and one in which the conduits are staggered and in which the radiating-fins provide an equal amount of surface for each This is effected by employing conduit. 7 gang-fins for engagement with a plurality of con uits and arranging these fins diagonally, so as to connect the staggered conduits;

A represents the conduits for the fluid-circulating medium, which are arranged in a plurality of arallel rows a a 1, the adjacent -members 0 each row being connected at their ends by return-bends B. The conduits of adjacent rows are staggered in relation to each other, so as to interrupt a direct air-passage between conduits in a direction perpendicular to the longitudinal axis of the radiator.

C represents the radiator-fins. For this purpose I employ a gang-fin, which preferabl extends completely across the radiator an is sleeved upon a conduit in each of the parallel rows. These fins are also arranged to extend diagonally, so as to engage with the staggered conduits in the different rows, which are out of line in a direction. erpendicular-to the lanes'of the rows. T e ends of the fins are, owever, cut at such an angle to the sides that they extend parallel to the rows of conduits. At the opposite ends of the rows of conduits are arran ed a series of fins c, which are of substantial ytriangular' form and with their outer sides completing the rectan le of the radiator.

ith a radiator constructed as described the cooling air-current, which is directed at right angles to the longitudinal axis of the raidator or the planes of the rows of conduits, will come into contact with the conduits in each row, while the common fin connectin these conduits will uniformly distribute an equalize the heat conducted thereto. All of the available space between the conduitsis filled with the fins C, and an equal area of the surface of said fin is within range of each of the conduits upon which it is sleeved.

To further increase the effectiveness of the radiating-fins, they are preferabl punctured to form apertures 12 therein an projecting points 0.

What I claim as my invention is- 1. A radiator comprisin a pluralit rows of conduits with the in ividual con uits of adjacent rows staggered in relation to each other, gang-fins sleeved upon and connecting the conduits of adjacent rows, said fins together' completing and substantially filling the rectangle surrounding said rows of conduits, whereby all available space for radiating-surface is utilized.

2. A radiator comprising a plurality of rows of conduits With the individual conduits of adjacent rows sta gered in relation to each other, gang-fins of r omboidal form sleeved upon and connecting the staggered conduits of adjacent rows, triangular fins sleeved upon conduits at o osite ends of the rows, said 10 fins together 1 ing the area of the rectangle, bonding said rows of conduits.

In testimony whereof I affix my signature in presence of two Witnesses.
