Toja/ZZ'. whom t Inlay concern/.f

Be it known that I,-LOUIs H. BRINKMAN, a citizen of the United States, residing at West Hartford, in the county of Hartford and State of Connecticut, have-invented a new and use? ful Improvement in Radiators for Motor-Vehicles, of which the following isa specification accompanied by drawings forminga part. of the same, in wliich- Figure 1 is a front view of'my improved radiator represented as, applied to a motor-vehicle. Fig. 2 is a verticalsectional view'on line 2 2, Fig. 1. Fig. 3 is a vertical sectional view through oneend of the radiating-pipes, taken on a plane at right angles to that shown in Fig. 2; and Fig. lLis a detached view of one of the radiating-plates.

Similar reference-figures refer to similar parts in the dilferent views.` i

My invention relates to that class of radiators which comprises upper and .lower waterchambers, between which the water to be cooled is caused to circulate'by gravity or aforced circulation through aseries of serpentine pipes or restricted water-conduits, said pipes lbeing in contact with a series ofradiating-plates, by which the radiating-surfaceexposed to the air. is enlarged and the eficiency of the apparatus increased; and my invention consists vin the construction and arrangement of parts, as hereinafter described, and pointed out in the annexed claims. I- f v y I Referring to the accompanying drawings, l denotes one of my improved radiators-mounted 'u pon a motor-vehicle and comprising an upper Water-chamber 2, having an opening at theY top by which the apparatus may be filled cov' cred'with a cap 3. 4 is a lower watercharn' ber,` said

chambers

2 and 4 being connected in the usual manner with a water-circulating system which includes the jacketed cylinder of# an explosion-engine, and may also includefif desired, a centrifugal pump or othermeans for maintaining an active circulation through the radiating system. g

denotes one of a series of pipes communi-A cating at 6 with the upper water-chamber 2 and at 7 with'the lower water-chamber 4, said parallel horizontal sections 8, preferably Vconnected at their ends by return-bends 9. The several pipes 5.are preferably arranged side in Fig, 2,` each being connected at its'opposite ends with .the upper* and lower water-

chambers

2 and 4.. Strungupon the horizontal seetions 8 of the pipes are a'series of parallel vertical radiating-plates 10, one of which is repsheet'metal whose length equals the vertical pipe being returned upon itself in a series of by side in the same horizontal plane, as shown i distance between the Water-chambers 2 and4 n and whose width equals the depth of the waterchambers'. These radiating-plates 10also'serve as a reinforcement or stiffening of the pipes 5, which are otherwise held only at their ends, andthese plates also unite all the pipes of the` water-circulatory.system 'into a more or less rigid framework. Thisfunction of increasing l the rigidity of the pipes '5 is assisted by the fact that the plates 10 are fastened attop and bottom to the water-chambers, The'plates 10v areprovided with openings 11 to receive the pipes 5, Y

and the openings l1 are provided with annuylar anges 12, integral with the plate 1'0 and formed by drawing a portion of the plate in the operation of forming the opening 1414. By so drawing the annular'flanges a complete..

ring is formed in contact with the pipe, thus increasing the area of radiation between the anges and the pipe and 'materially assisting the cooling of the water. A 12 are preferably punched from the plate 10 alternately in oppositedirections from the top'v to the bottom of the plate, the upper series of openings for the water-pipes having their` annular'flanges upon one side of the plate and the next lower series o f openings having ltheir "flanges upon the opposite sides of the plate.

The length of the annular lianges 12 is equal to the desired distance between the plates 10,

The annular anges.

so that when the plates are. strung upon the f water-pipes the -anges upon 'theplates are brought into Contact with the next adjacent i plate, as represented in Fig. 3. The upper- .and lower ends of the plates .are`preferably turned over t'o forrnanges 1313, which may be soldered to the surfaces of the

Water'c'hambers

2 and 4, and the flanges 12 may likewise bent into serpentine convolutions, said serpentine convolutions being arranged in vertical and horizontal rows, of aseries of plates extending, from top to bottom'of the Waterpipes, eacli plate uniting all the serpen tine cony volutons 1n said horizontal and vertical rows,

thereby securing said pipes in position.

2. In a radiator for'motorrvehieles, the combination with a series ofwater-pipes forming annular flanges surrounding said pipes and in part of a Water-circulatory systermof a series Y of radiating-plates provided with openings to "receive said series of pipes, each Aplate having contact therewith,lsaid Aannular anges being arranged'on opposite sides of said plate.

3. .ln a radiator for motor-vehicles, the cornbinationwth a serpentine pipeA forming part of a Water-circulatory system, of a radiating- 'plate-having openings'for separate convlutions of the pipe, said opening provided with complete annular anges integral with the plate and'inl contact withsaid pipe.

per and a lower water-chamber, a series of lpipes connecting said chambers, said pipes being bent into serpentine convolutions inter- 'posed between said water=c`haxnbers, and a series of radiating-plates extending from the upper to 'the lower Water-chamber and having their ends attached thereto, said plates having a series of openings for said pipes and a series of vannular flanges integral with they platesand inclosing said pipes. f
