useful Improvements in Radiators, of which the following is a specification.

My invention relates to radiators for automobiles and its objects are to provide a radiator having a single unit of construction whereby facility and cheapness in manufacture are obtained and the construction rendered capable of being readily repaired; to provide a construction unit of such form that the elements may be readily assembled and such that when so assembled a large radiating surface relative to the mass of metal employed is obtained, and such that a large radiating, air cooled area relative to the volume of water passing over any given section at a time is obtained, and whereby the water is caused to travel slowly through the radiator thus insuring the effective cooling of the same.

\Vith' these objects in view my invention is embodied in preferable form in the construction and arrangement hereinafter described and illustrated in the accompanying drawings. I

In these drawings, Figure 1 is a front view in elevation, partly in section of a radiator showing my improvement applied thereto and showing the ends of the plates before the application of solder thereto; Fig. 2, an enlarged detail vertical section of part of the core; Fig. 3, an enlarged detail vertical section showing two of the identical plate units spaced apart but in the relative positions they are adapted to occupy when assembled; Fig. 4, a detail perspectlve view of one of the unit plates; Fig. 5, a side view in elevation of one of the main plate units; Fig. 6, an enlarged detail vertical section of a form of plate which may be used in conjunction with the units illustrated in Figs. 1 to 5 inclusive and Fig. 7, a vertical section of a core showing the plates illustrated in Figs. 1 to 4 inclusive employed in conjunction with the plate shown in Fig. 6.

- Referring to the drawings, 1 indicates the casing of the radiator and 2 the water-receiving chamber at the upper part thereof. Within this casing is adapted to be disposed the core formed of the separate units consisting of thin metal plates, the faces of which lie in planes extending from front to rear of the radiator. The lates constituting the constructional units of my invention are adapted when assembled to form what is known as a honeycomb core. 3 indicates one of these units, the cross sectional form of which is indicated more particularly in Figs. 2, 3 and 4. Each of these plates has vertical plane sections 4 adapted to constitute the Walls of vertical water channels 5, when two units, turned in opposite directions, are placed together as indicated in Fig. 2. Each plate is provided at vertically spaced intervals with transverse hollow channel-forming fins "6 which extend at right angles to the vertical plane faces of the plate. Between each pair of adjacent hollow fins, each plate is provided with a flat, solid, closed flow-interrupting fin 7 projecting at right angles from the face thereof which is opposite to the face from which the hollow fins project. The adjacent units are adapted to be positioned as shown in Fig. 3 with their respective hollow and solid fins projecting in opposite directions and with the fiat solid fins on one plate 0 posite-and adapted to enter the correspon ing hollow fins on the adjacent plate. When the units are placed together, they occupy the position indicated in Fig. 2.

Each plate unit is provided along its vertical front and rear edges with an inwardly projecting shoulder or flange 8 which extends beyond the inner face of the plates and which raised shoulders constitute means that are adapted to space apart centrally two adjacent plates when the latter are placed together so that the proper water receiving channels are provided between the plates. When these plates are assembled With a core constructed as illustrated in no Figs.,1 to 5 inclusive, the water will enter throughthe open tubes 9 at the upper end of the core and thence pass into the vertical water channels 5. The water will then strike the interrupting and diverting flat, thin, solid fins 6 and be carried over at right angles to the face of the plates into the channel provided by the hollow fin into which the corresponding solid fin fits. The solid fin reduces the cubical capacity of the channel of the hollow fin, and, owing to the fact that the outer top and bottom faces .of the hollow fins are comparatively wide, a large air cooled area relative to the volume of water passing through the fins, is provided. The same is true with respect to the Vertical walls 4 relatively to the channels inclosed thereby. Owing to the interfitting of the hollow and solid fins and the pro ection in alternate directions of the successive pairs of fins, the water is effectively retarded in movement, being caused to pass first downward and then to the right and then back, then downward again and then to the left and then back again to the vertical channel, which slow passage of the water will insure that the same will give up its heat before it reaches the bottom of the core. The construction of the unit plates not only obtains this effective slow tortuous passage of the water but such construction is one that'may'be very readily and cheaply formed owing to the shape and angle of the fins.

In Fig. 6, a plate is shown provided with solid fiat right angled fins only. This plate is designated by the numeral 10 and the fiat fins 11 thereof project alternately from opposite sides of the plate. Fig. 7, shows an assembled core employing the plates 10 in conjunction with plates such as 3. In this assembly each third plate is in the form of a plate 10 and each flat solid fin thereof is adapted to bear against the outside closed end of one of the hollow fins of a plate 3 on one side and against the plane face of another adjoining plate 3 on the other side. This arrangement may be used when it is desired to form a core having less metal than the construction of Fig. 2 and when it is not necessary to employ as great an area of water circulating space as in the form illustrated in Figs. 1 to 5 inclusive.

Having thus described my invention, what i I claim is:

j 1. A radiator unit consisting of a thin plate of metal having alternate hollow fins and solid flat fins spaced apart vertically.

2. A radiator unit consisting of a thin plate of metal having hollow water channel fins projecting from one face thereof substantially at right angles thereto and spaced apart vertically and solid fiat fins projecting from the other face of the plate and each located between adjacent hollow fins.

3. A radiator having a pair of circulating and radiating plates each composed of a unit having hollow water channel fins projecting substantially at a right angle from one face thereof and spaced apart vertically and having flat solid fins projecting from the opposite face thereof and disposed successively between adjoining hollow fins, said pair of units being adapted to be placed together with the-flat solid fins projecting into the hollow fins of the opposite plate.

4. A radiator comprising plate units having vertical plane faces adapted when two plates are placed together to provide vertical water channel walls, the walls of adjacent plates being spaced apart at their upper ends to provide water entrances, and each plate having hollow fins projecting from one face thereof substantially at right angles thereto and having solid fiat fins projecting from the other face between the 1101-
