RADIATOR. g 1

Be it known that I, JAoon B. BnAM, a citizen of the United States, residing at Punxsutawney, in the county of Jefferson and State of Pennsylvania, have invented.

v certain new and useful' Improvements in easily repaired when for any unusual reason Radiators, of which the following is a specification.

. My invention relates particularly to radiators of the class employed on automobiles object of my invention is to provide a radiator of this class which shall be strong and durable, not liable to leak and which can be any of the parts are accidentally broken.

- A further object of my invention Is to so construct the radiator that any desired design may be employed for the front thereof "and yet radiator sections may be employed which can be inserted in or removed from therear portion of the radiator frame" without detaching any part of the front frame or disfiguring the front frame wlth A further object of my invention is to provide circulating tubes of improved construction in which the water as it circulates is more thoroughly agitated and brought into contact with the cooling surfaces.

Other features of my invention will be more fully hereinafter explained.

In the accompanying drawings,-Figure 1 is. a View in front elevation with parts broken away and parts in section'of an automobile radiator with my improvements applied. Fig. 2 is a detail view in horizontal section of one of the radiator tubes. Fig. 3 is a perspective View of the radiator with parts broken away and parts in section to more clearly showv other parts. Fig. 4 is a detail view in perspective showing the construction of the upper portion of the radiator frame at the front and side thereof. Fig. 5 is a perspective view of one of the independently remoxable radiator sections.

Fig. 6 is a perspective view of the lower front portion of one sideof the radiator frame. Fig. 7 is a detail view in dotted lines showing how the bottom of the radiator frame containing the lower water chamher is lowered away from the side frames when it is desired to remove one or more of the radiator sections. Fig. 8 is a side elevation of the radiator shown in Figs. 1 and away for the purpose of illustrating'other parts. Fig. 9 is a detail view on an enlarged scale and in section showing more clearly the construction of a radiator section. Fig. 10 is a detail View in perspective and in section showing .how the headers of the radiator sections are constructed. Fig. 11

is a perspective view of a portion of a radiator tube. Fig. 12 is'a similar view but showing the parts in section. Fig. 13 is a plan view of a blank from which a radiator tube constructed in accordance with my invention is made.

The upper water chamber A is cast in one integral piece without seam and it has cast integrally with it a front frame consisting of the front pieces a and side frames consisting of the side pieces a, (see Fi 4). The front and side frames extend ownwardly, as indicated in Fig. 8, and are formed integrally with a bottom front piece a. It will thus be seen that the upper water chamber, the sides and the front of the radiator frame are all cast together without seam and there is no danger of seams being projecting ears a on which rests thesheet metal ornamental cover A which is secured to the frame by means of rews a applied at suitablepoints. Below the ears ,(1 the sides a are formed with ears or flanges b,

as clearly shown in Figs. 1 and 6. The

filling tube X has a threaded connection at w with the top of the u per water chamber A and it is provided with a removable cap By removing the screws (1 and the tube X the cover A may be lifted up and removed from the radiator frame. This cover A may be stamped or pressed from a single piece of sheet metal and is not permanentl'y connected or formed with the radiator frame as in prior constructions.

The lower water chamber C is formed in the bottom part B of the radiator frame. This bottom part of the frame, the construction of which is clearl indicated in Figs. 1 and 3, comprises a ottom 0, sides a and a top 0 The sides 0 extend above the top 0 and their upper edges are flush with the upper edges of the framepiece a.

3 with parts in section and parts broken The ends of the water chamber are closed 'at' and the upwardly projecting portions the bottom frame B with the side frames.

This is clearly illustrated in Figs. 1 and 8. Rubber washers .2 and metal washers z are threaded on the bolts and are interposed between the heads of the bolts and the 'flanges 0*." In this way a pressure is produced which holds the joints tight but re-J- lieves the strain when it is abnormal. By this construction the bottom of the radiator frame may) be separated from the other portions of'the frameor readily connected therewith. The top wall 0 of the waterj chamber C is formed with a series of bosses d having seats d" containing packing, as shown, and adapted to receive bosses on the radiator sections, as hereinafter described The chamber V0 is inclined at the bottom from one side of the radiator to the other, as indicated in Fig. 1, where it is connected with an outlet E in turn connected with the Water jackets of the engine. e indicates a draining cock. v

Returning now to the upper part'of the radiator, the part F is alug constructed to receive the hinge rod of the hood commonly employed in automobiles and the part marked F is adapted to receive a rod extending to the dash-board of the automobile. The hood is received in the I depressed portion f of the top wall of the upper water chamber which chamber is provided with a connection F for a pipe leading to the Water jackets of the engine. The bottom wall of the water chamber A has a horizontal portion 9 formed with bosses 9 having packed seats for corresponding bosses on the upper ends of the radiator sections and the horizontal portion g is'connected by an inclined portion 9 with another horizontal portion'g at a lowerlevel than the part 9. In this way a recess is formed in the bottom of the water chamber-A adapted to receive the top head-- ers of the radiator sections so that the lower walls thereof are above the plane of the top edge of the opening in the radiator through which air circulates. Thus the upper header is hidden from view and does not obstruct the passage of air through the 'ra- 'diator. By providing the inclined wallv 9 space is economized and the radiator heads are made to fit closely in place and can be easily detached. The upper and lower wa-. ter chambers are connected by vertically arranged radiator tubes which extend at their upper and lower ends intoheaders, which headers communicate with the water cham-' bers. These headers are made in sections which with the tubes connected with them are separately removable from the rad'iator. frame. In the drawlngs I have shown each set of headers carrying .five radiator tubes and have illustrated six setsof headers tubes. These sections with correspondin each other and can be are independent 0 frame or inserted-therein. Each radiator section comprises an upper header H and a lower header I connected by verticaltubes J. The headers H'and I are of substantially the same construction, and the details of construction of one of them is shown which comprises the top, sides and ends of the header; is made of a single casting while the part h is preferably made of sheet metal joined in any suitable way at 71. to

separately removed from the radiator clearly in Figs. 9, 10 and ll. The part b, I

the lower edge of the casting. The top of the casting'is formed with an annular boss or flange k adapted to enter a socket at g (see Fig. 8). The lower header, while of the same construction, is of course, re

versed, the parth' being at the top and the.

boss k at'the bottom. The part h is of the construction shown more clearly in Fig. 10, consisting of a slotted plate having beveled edges h adapted to connect with the beveled edges h. cast all in one piece, 2'. e.,' with the bottom 7 71. formed integrally'it' would be diflicult and expensive to form the slots in the castmetal to receive the tubes J, but by making the part h" of sheet metal, it can be stamped into.shape with the slots by an inexpensive operation. In this way the cost of the header is considerably reduced.

The tubes J are made in an improved way. Fig. 13 illustrates the formation of-the blank" for this purpose. A sheet of metal K is formed with two series of parallel grooves .70, 7a which have on the opposite sides corresponding ribs. 'Between alternating parallel grooves are formed transverse relatively short grooves and identations h. It will be observed by reference to Fig. 13 that. the grooves and ribs 70 in the top series at the right hand side are three in number and are in line .with a space between the two uppermost grooves and ribs on the opposite side of the sheet which has'no parts 70 In the next space, however, between the ribs 70 at the left there are the parts 70 which are four If the header H were V in number and which are in line with a blank space k at the opposite side of the sheet. The blank in this condition is bent on the line L until itas'sumes the condition shown in Fig. 11, the edges being .overlapped and secured at Z by solder so as to make a water-tight joint. The construction of the tube thus formed is more clearly illustrated by the sectional view, Fig. 12, where it will be seen that the tube has a channel running through-it from top to bottom which is formed with lateral ofl'sets at k.

. which branch in o posite directions andbetween'each two 0 which offsets or ooves k there are vertically arranged pro ect-ions 70 the construction bein suc that as water passes downward throug the vertical channel t spreads into the offsets lg and then passing down past the pro ections k the water 15 divided and agitated, then spread into 'the next offsets k and so on. This irregular movement of the water through the tubes so agitates it that It is brought more intimately into contact with the walls of the tube and into the range of action of the cooling air which passes between the tubes. The projections 10*, in addition to the function above described, also serve to hold the opposite sides of the bodies of the tubes apart and properly spaced. The tubes thus constructed are connected with the upper and lower headers in the manner indicated in Fig. 9. The lower ends of thetubes are first passed into suitable openings in the top wall of the lower header I and are soldered therein, and then the upper ends -of the tubes are connected with the lower plate h of the upper header and are soldered thereto. Before soldering, the tubes are inserted to a sufiicient extent to provide a space between the upper wall of the top header and the lower wall of,the bottom header that will just fill the space between the bottom wall 9 of the' upper water chamber and the upper wall a of the lower water chamber, so that a tightjoint may be formed between the upper a d lower ends of the radiator section and t e walls of the water chambers. In order to insert the radiator sections, the bottom section B of the frame containing the water chamber C is detached from the frame, then the radiator sections are inserted, the bosses or flanges k fitting into the sockets in the bosses g in the upper water chamber which, as before described, are packed. When this is done the lower section B is lifted, the bosses h are made to enter the sockets in the bosses d, which are properly packed, and then the bolts D are screwed home to firmly and rigidly connect the parts. All of the radiator sections are applied in the same way. Any one of them may be separately detached, it being necessary for this purpose only to remove the bolts D, or to unscrew them to a suflicient extent to allow the bottom section B to lower to a suflicient extent to permit the bosses k to be separated from their sockets, then any section may be removed without disturbing the others and may be replaced by a new one, or the openings to which they were connected may be plugged temporarily so that on the road the radiator may be used with one section removed for a time or until a repair shop is reached. The ofl'sets 7: not only provide fon the lateral spread of the water, but as clearly shown in Fig. 9, the

offsets abut against each other, hold the tubes-properly. spaced and brace them so that a rigid structure is obtamed.

' The construction shown and descrlbed is such that the radiatorsections are supported not entirelyby securing bolts but mainly by the bottom of the radiator frame, means being provided for quickl removing an 111- jured radiator section an replacing it. The joints are all tight. There 1s no danger of leakage and the radiator tubes are of such construction as to insure such a circulation of water as to quickly cool it, and'the construction of these tubes is also such that they mutually support and brage each other.
