A; Atty r at SAUL BER/MANN, OF NEW YORK, N. Y.
RADIATOR.
Specification of Letters Patent.
Patented May 23, into.
Application filed February 18, 1915. Serial No. 8,993.
To all 2072017! it may conccrn Be it known that I. SAUL BERMANN, a subject of the Czar of Russia, residing at New York city, New York. have invented certain new and useful Improvements in Radiators, of which the following is a specification.
My invention relates to improvements in radiators, particularly for automobiles, and has especial reference to the construction and arrangement of the supporting ribs or fins for the radiator tubes.
As is well known in the art, the radiator tubes require cooling to provide for the radiation of enough thermal units to keep the water in. the tubes from changing into vapor form. At the present time, air cooling of these tubes is most generally resorted to, and my invention is especially concerned with air cooled radiators.
It is of course eminently desirable that all the tubes of a radiator shall be subject to uniform cooling action of the air but it has been found, in practice, that with the present construction of supporting ribs or grids. the end tubes are more vigorously cooled than the intermediate tubes.
The principal object of my invention is to provide a construction of radiator inwhich all the tubes will be subjected to adequate air-cooling.
A further object of the invention is to provide a form of ribs or supporting grid which need not be connected with the radiator tubes. although forming an effective support therefor. The individual ribs of the grid are preferably provided or formed with means to prevent damaging the tubes by contact of the ribs therewith, and with means for connecting the ribs together.
The invention will be clearly understood from the following description thereof. in
connection with the accompanying ing, -whercin Figure 1 is a front elevational view of an automobile radiator constructed according to my invention; Fig. tional viewthcreof on the line 2-2 of Fig. 1; Fig. 3 is an elevational view of a number of ribs assembled to form a grid; Fig. 4 is a plan view of Fig. 3; Fig. 5 is a similar View of a forn'ied up rib; Fig. (3 is a cross sectional view on the line 66 of Fig. 5; and Fig. 7 is a plan view of a blank from which the ribs are formed up.
Referring to the several figures of the draw- 2 is a horizontal. secdrawing by reference characters, 10 denotes the water tank of the radiator, the parts of which are interconnected by the upright radiator tubes 11. To support the tubes 11 in position. and provide for regulating theflow of air thereto, 1 place adjacent these tubes one or more grids, wnich are built up of superimposed units or ribs, preferablv constructed of blanks such as shown in Fig. 7. The blank, which is of rhomboidal form. includes a plane body portion 12, longitudinal lateral flanges 13, and ears 1% at opposite ends of each flange. Traversing the body portion 12 diagonally is a slot 15, which extends substantially the length of the blank.
To shape the blank for the purpose of forming the same into a rib of the desired shape, the flanges 13 with their integral ears 1% are bent along the lines 16, at substantially right angles to the plane of the body portion 12. This operation results in producing a rib such as that shown in plan in Fig. 5, and in cross section in Fig. (3.
The supporting grid is formed by superimposing any desired number of such ribs in vertical alinement, and suitably connecting, as by means of solder or otherwise, the ears 1% of one rib with the next higher succeeding rib. If desired. the ribs may be additionally interconnected and reinforced by the rods or wires 17 engaging in grooves formed in one end edge of the ribs. A grid of this kind, or a number of such grids, may be placed between adjacent series of tubes 11 (Fig. 2) the upturned flanges 13 resting against the tubes. These flanges are smooth. and are thus not likely to injure the tubes as a. result of the vibration to which a vehicle radiator is normally subjected.
In connection with the grids above described. I prefer to employ means for regulating the flow of air to the tubes 11. The preferred means comprise deflector plates 18 inserted through the slots 15 in the ribs 1 Each plate 18 is approximately as wide as the slot 15 is long. and may be made sufficiently high to extend of ribs forming one or more grids. plates are i'ibliqnely placed, (the slots 15 being oblique) and so guide the air which passes. between the tubes that the intermediate tubes will be as well cooled as the end tubes. It will be understood that ordinarilv a fan is carried by the vehicle near through the series These ates this defectby deflecting the air from its 10 of a series of superimposed ribs each therethe inner side of the radiator, such fan cooling the inner radiator tubes, While the inrushing a r s relied upon to cool the outer and intermediate tubes,
- As above stated, it was found in practice that the intermediate tubes were notadequately cooled'by the air flowing past the same, and" my improved construction'obvinormal straight path'between the tubes, and causing it to follow a path inclined from one side or end of the tubes to the other. In
and desire to secure of being provided n ith a slot extending substantially from end to end of the rib and inclined toward the radiator tubes, and a deflector plate eatending through the slots in the ribs.
2, A radiator construction pose specified, comprising radiator tubes, a, supporting grid therefor consisting of a series of superimposed ribs includes a body portion having a longituditor tubes, and also having lateral flanges and ears pro ecting from said flanges, and
deflector plate inserted through the inclined slots in said ribs. Y
In testimony whereof I have-afiixed my signature in presence of two Witnesses.
