RADIATOR.

No. 892,761. Specification of Letters Patent.

Patented July 7, 1G08.

Application filed September 16, 1907, Serial No. 892,973.

To all whom fit may concern:

Be it known that I, GEORGE W. NTz, a citizen of the United States of America, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a specification.

This invention relates to radiators or coolers used more especially in connection with the water cooled explosion engines of automobiles andthe like; and. the present improvement has for its object to rovide a simple and economical structure arrangement and combination of parts adapted to afford a maximum amount of effective cooling surface in a very compact manner, all as will hereinafter more fully appeal'.

In theaccompanying drawings z-Figure 1y is a front elevation of a radiator embodying the present improvements. Fig. 2 is' an enlarged vertical section on line -x Fig. 1.

Figp is a horizontalv section Online z-x Fig. 1. Fig. 4 is an enlarged detail section on line aL-:x2 Fig. 2.

Similar numerals of refel'ence indicate like parts in the different views.

Referring to the drawings, 1 and 2 represent upper and lower horizontal members, and 3 and 4 vertical side n'iembers, which are connected 'together to forni a substantially rectangular water containing casing, thecentei' of which is open and contains a series of vertical radiation tubes 5' connected at top and bottoni to the respective upper and lower members l and 2 of the casing. Such nconstructiin is common to radiators used in connection with the water cooled engines of automobiles and the like.

ln connection with the construction of radiators above set forth, the material part of the present invention involves a construetion and arrangement of parts as follows l are/a series of vertical tubes arranged within the radiation tubes 5 aforesaid. Such tubes Gare secured at their lower ends to the bottom plate of the lower section 4, and at their upper ends to an intermialiate plate 7 oftheuppcr section 1, with their respective ends open to the atmosphere to permit a circulation of air through their interior.

ln the preferred l'orui of the present invention and as shown in the drawings, the intermediate plate 7 constitutes a portion of a curved throat formed in the upper section l, the other portion of said throat being formed by a curved plate 8. In the forward inovement of an automobile or the like, such` throat is adapted to deflect aA current of air down through the series of tubes 6,to aid materially in the cooling action of the apparatus. A marked advantage of the resent construetion being that the water to e cooled is in the foim of a thin annular stratum inclosed between said tubes with both inclosing surfaces adapted for atmospheric radiation.

9 are one or more horizontal plates ar fully 'described my said'iinper and lower horizontal members and vertical side members forming an open center, a' series of radiator tubes arranged in said center and a series of secondary tubes arrangedwithin the radiator tubes and open to 'the atmosphere at both ends, one of the casing members having a curved inlet` throat formed by a ilat plate to which the secondary tubes are attached at one end and a curved plate forming a defiector for directing the air into the secondary tubes, substantially as set forth.

2. ln a radiator of the type herein described, the combination of a casing comprising upper and lower horizontal members and vertical side members forming an openceiitef, a series of vertical radiator tubes arrangedin sait .centery and a series of secondary tubes arranyvfd within the radiator tubes and open to the atmosphere at both ends, the upper casing member having a curved inlet thro'at formed by a flat plate to which the secondary tubes are attached at their upper ends and a curved plate forming a detlector for directing the air into the secondary tubes, substantially as set forth.

Signed at Chicago', Illinois this 13th day of September 1907. GEO. W. NTZ. Witnesses:

Roemer BURNS, HENRY Mon.
