T at whom, it may concern.-

Be it known that I, WARREN S. JoHNsoN,

a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Condensers or Radiators, of which the following is a specification.

' My present invention pertains to improvements in condensers or radiators, designed primarily for use in conjunction with steam engines or explosive engines employed in automobiles.

T he object of the invention is to provide a simple and eflicient structure, which may be readily manufactured'and will present a' minimum number of joints.

In the drawings: Figure 1 1s a front elevation of the radiator, which term Will be herecolumns bearing a staggered relation. to each other. The various columns of tubes are spaced apart by strips or bars B, which are placed between said columns at each end 'of the tubes, the spacing-strips or bars being of the form illustrated in Fig. As will be seen upon reference to said figure, the strip is formed of a piece of metal oblong in crosssection, and so'shaped as to present a wavy outline, or a series of-convexrconcave surfaces. When the elements are assembled, these spacing-strips lie directly against the faces, or a portion thereof, of the tubes which. they separate, thus forming spaces C between the various vertical columns of tubes, the tubes which compose each column lying directly one upon another. The spaces thus produced are tortuous or serpentine in form, thereby exposing the steam (or water, as the case may be) to an extended surface in its passage through the radiator, which surface is much greaterthan would be the case if the passages were straight.

After the tubes and spacers are assembled, they are temporarily secured and then the opposite ends of the bundle are dipped in solder, preferably to a depth greater than the width of the strips which are placed at theends of the tubes, as shown. The solder, indicated by D, Fig. l, flows around theends of the tubes and the spacing-bars or strips, effectually binding them all together, thereby forming the series of verticallyalisposed channels or spaces C, heretoforeireferred to. Inasmuch as thetubes in the columns he immediately one upon another, no cross-- the adjacent faces of the superimposed tubes,

due to inequalities and other causes. The spacing-bars being wavy or serpentine in form, it will be seen that the separate tubes in each column are embraced by the bars, and one bar or spacing member is common to two adjacent columns. The solder employed firi'nly binds the elements of the structure together, and fills up the triangular, Oi substantially triangular, spaces or openings left between two adjacent tubesand their .bars. The width of the spaces between the columns may be varied as desired, by employing spacing-strips or bars of a greater or less thickness.

' In practice the structure will be mounted in a suitable frame or casing, having connec? tions with the steam exhaust of an engine, or placed in the line of, circulation from' and to the water-jacket of an en losive engine, as the case may be. It will aso be understood .that while I have referred to the spaces C as being yertically disposed, they mayrun horizontally if so desired. So, too, the term column is employed in a relative sense. The term row. would bev applicable were the tubes arranged with their longitudinal axes in a vertical plane. The claims are to be read and interpreted with this -understanding.

rraving thus described I claim is 1. In combination with a plurality of col umns of tubes, each column comprising a series of tubes curved in contour, arranged side ,to side; spacingmembers placed between the adjacent columns at each end thereof, each of said members conforming in shape to the contour of that portion of the tubes with which it contacts and solder securing th invention, what together,

'2. In combination' title a plurality of colends of the tubes. and the spacing members umns of superimposed tubes, the tubes when assembled, presenting a substantially conat each end of the tubes embracing each of the tubes of the column which lies between them-;- and-solder securing the ends of the.

tubes and the spacing'members to ether.

3. In combination with a plura ity of columns of tubes, each column comprising akse ries of tubes ,arranged in contact with each other and side to side and presenting a substantially continuous sinuous face, the tubes of one colunm being staggered with relation to those standing adjacent thereto; spacing "and spacing members together:

In testimony whereof I have signed my name to this s ecifica-tion inthe presence of two subscribing witnesses.
