To all whom it may] concern. i

lie it known thatJ MAX KAMAN, a cltiaen of the United States, residinga-t Syracuse,

in the county of Onondaga and State of New York, have invented certain new and useful.'

improvements in Radiators for itutomoif ratus known to Sii als

biles, ot' which the following is a speciiication. I

This invention relates to improvements in radiators, oi' the class employed for cooling the Water which protects the cylinders of automobile motors, and has for its object to provide a novel, simple and effective water cooler, wherein a greater radiating surface is provided for a given quantity of water, thereby more readily and more quickly cooling 'the water, than under any other appa- And a further object is to prdvide 'a radiator of the class, which is sectional, and wherein eac-h section is capable otiloeing,r applied, removed or replaced without disturbing the other sections.

The various features, as Well as, the `parts of the invention will be `anderstood from the detailed description-which follows, wherein reference is made to the accompanying drawings, in which- FigureV 1 is a front elevation of the corn# plete radiator. Fig. 2 'is afhorizontal section taken on line 2-@2 ci' Fig, 1. Fig. 3 is an enlarged vertical sectiomtaken on Aline 3 3 of Fig. 2. Fig, et is an enlarged pentral vertical cross-section on line et'A Fig. 1. Fig. 5 is a rear side elevation of the complete device. Fig, 6 is an isometric view, showing the construction and arrangement of the radiating parts; also showing the-method of applying the same tothe frame.'

Similar characters of reference are assigned to corresponding parts throughout the several views.

The drawings illustrate one formof my improved radiator, in which 2 represents a hollow frame or body, having relatively large front and rearopenings' and 4, which correspond in location, size and shape.

5 represents a'lling spout or neck which is disposed atthe top of the bod 2, by means of which the'water for coo ing the motor-cylinders (not shown) is supplied. The hot water is carried from the motor to the top portion ofthe radiator by means of l I `a tube or pipe 6. i After the Water is cooled it is carried beck to the motor by a pipe 7, which draws the vwaterfroim near thepbottom Patented Ang. 1G, lll.;

application liled iarch 8., 19152. Serial No. 252,855 v of the radiator, The cooling of the water is accomplished by means ot a ser1es of tubes or fines, which are preferably square and grouped-'in similar detachable sections, as 8, 56

9, 10 and 11, each of which consists of simi-V vlar front and 'hack plates or heads 12 and 13,. and. a number ot the tubes l5, which are preferably horizontally disposed.` :The plates 12 and 13 'have a relatively large num' 55 ber of coinciding perforations 14,-in whichv the tubes 15 :are inserted, for,p1j0viding:as

many normallyv open lues. through whichi the air passes during the travel ofthe carga." The tubes' 15 of each of 'the sections 'are 70 spaced equi-distantly, .preferably in v vertical 7j and horizontal rows, as shown, andthe tubes are preferably held by the plates 12 and 13 so as to provide clear spaces 15 of one-sixi teenth to one-eighth lof an inch between the` .15. adjacent tubes, which spaces lare filled `with the hot water as it gravitates' fromfthe topv if' to the bottomef the tank 2. The several. sections 8, 9, 10 and 11`When placed in' the frame substantially close orll the central .'30 openings 3 and 4, and together comprise butA a single radiating field, as there are no barriers or partitions between the ilues of the adjacent sections. The water,"iiihether en tering the radiator ,through the 'lling tube 85;?"

5, or the pipe 6, falls upon the topmost tier of thel radiating fines 15, of the section 8, and thence circulates or Hows around and between all of the lines of the severa'isec-'f tions, unt'il it finally reaches the free or clear in, space (2 in the bottom of the tank, from" which it discharges through theV pipel 7,-; rlhe correspondingplates'12 and 13 of the. several sections of the radiator,`wl1en the latter are placed in the frame 2, preferably sa aline with each otherland-also with the free lateral edges of the frame openings-3 and/1, To render the jointsbetween the sections, as well as between tlfe ends of the section plates 12 and 1S and the rame'- 2 water 10e tight, eac-i1 of said points is preferably` covered with strips otthinmetal 16 and 17,

' which are preferably soldered in place.

To disconnect one or'more ofthe radiating sections for repairs, thel strips 16 and; 17. 10s may be readily and quickly removed from the front and back, by the use of a common solderingiron, after-which the sections may be withdrawn, as shown by, dotted lines in i Fig. l. v l 11,@

The .tank or body 2l is protected by a band-lke casing orshield 18, which surrounds the lateral edges and also partially crei-laps and gives a linished appearance vto the top and the sides of the front of the radiator.

The top of the casing 18 is provided with v a tubular part 22, which serves as a shield for the filling tube 5, and 28 represents a screw-ca p which closes the part 22, and also the mouth of the tube 5, by means of a balllike part 23". The casing or jacket 18 is detachably secured to an angular metal parth by bolts 20, and the part 19y is preferably to 'obviate the necessity of frequent replenishing of the cooling system.

llt/ly improved radiator is extremely simple, and owing to the number and close arrangement ofthe lues 15, it is capable of quickly and effectively cooling the water it receives from the motor cylinders.

The provision of a large number of radiating tubes 15 which are arranged to divide the body of the hot water into relatively thin sheets or columns, alords a. greater amount of radiating surface, without occupying'any more space, than any of the older styles of radiators, known to me. find furthermore, the grouping or arranging of the radiating tubes into sectionsof convenient size, which'are readily detachable in case of leakage or injury to any of the' tubes, is an essentially. novel feature which enhances the value of my improvement.v n p Having tlius described my invention, what I claim as new and desire to secure by Letters Patent, is-`- In a sectional radiator, the combination of a plurality. of sections, each section comprising spaced front and back plates, said plates having coinciding perfor-ations, and a series of tubes spanning the space between said plates, the ends of the tubes beingdisposed in the corresponding perfor-ations and' being flush with the outer faces vof said plates, the respective walls of the `tubes being spaced equi-distantly from the walls of the adjacent tubes, whereby to provide vertical and horizontal columns of Water of the same thickness surrounding each tube, the

`said radiator sections being disposed horizontally, and the front and back .plates of the respective sections projecting above and below the walls of the tubes of therespective sections and adapted to be connected to one another, whereby to provide a water space of substantial area between the tubes of the adjacent sections.

ln testimony whereof I ailix my signature in presence of two witnesscs.`
