Abstract

141,469. Booth, C. F., and Gillison, T. March 3, 1919. Plate apparatus. - Relates to radiators for internal-combustion engines or like surfaceapparatus of the type comprising a number of pairs of metal plates with protuberances stamped in them so that, when they are arranged in juxtaposition, two series of spaces are formed for the passage of the heating and cooling fluids respectively. In the construction shown in Fig. 2, the pairs of plates A are united round their entire margin D and are provided with relatively large convex and concave depressions B out of which central flanged apertures C of relatively small dimensions are pressed, these apertures forming tubular water passages communicating between the water spaces C<1>, and also spacing the pairs of plates apart to form the air spaces E. In the modification shown in Fig. 3, the depressions B are not perforated, but are flattened at their axes where they contact with the next pair of plates. Each pair of plates are united along one pair of edges, and spaced apart along the other edges so as to form water passages H. Pairs of plates are connected along the latter edges by distancepieces I so as to form air spaces E, and smaller depressions G are formed at the opposite sides of the plates to the depressions B so as to contact with each other in the water spaces H. The joints are completed by dipping in solder.
