RADIATOR.

Application filed June 22,

To all whom it may concern: I

Be it known that I, EDWARD T. CURRAN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Radiators, and declare the following to. be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification My invention relates to radiators such as are used principally in automobiles for Water cooling the engines thereof and it consists in the peculiar arrangement construction and combinations hereinafter specified and claimed.

In the drawings:

Figure 1 represents the radiator attached to an automobile.

Fig. 2 is a side elevation withthe hood removed.

Fig- 3 is an elevation of'the rear portion of the radiator looking from the front.

Fig. 4 is a sectional elevation of the upper portion of the radiator showing the arrangement of the connecting pipes through the sections of the radiator. I

Similar letters refer to similar parts.

In general my improved radiator as a whole is made of two or more parts. In the drawings I have shown two parts which are each connected to the engine by separate connections. Each part is composed of a front and a rear section connected together with an'air space between them. My object is to provide duplicate means for cooling the cooling water so that each section may be used independently of the other and also to afford by the double system a more efiicient means to that end.

In the drawings A represents a left hand section of the radiator and B the right handv section. These two sections are separable but in the same vertical plane and are adja-- cent to each other on the vertical line C. In. the rear of these two sections A and B are also two sections D and E having over all' substantially the same dimensionsas A and B. but are, through a portion of the elevation as shown in Fig. 3, narrowed. Sections D and E are Iplaced slightly lower than sections A and When the upper and lower edges of sections D and E are placed in contact'at H H they leave an opening J between the two sectlons. The usual Specification of Letters Patent.

passes over the radiator and incloses the their purpose being to permit air to be forced through when the car to which the radiator is attached is in motion whereby the air is concentrated and thereby increased in density, pressure and velocity in passing from front to rear through said sections A. B and thus caused to impinge upon the sectionsD E respectively. The section A on the one hand is connected to the section D by an inclined water pipe M which passes through-section D as shown in Fig. 4, having a comparatively small outlet N into said section. It passes into the section A at N with a comparativelylargerropening so that there is a freer circulation of the rising water passing into section A than that which asses into section D through the opening N. he sections B and E are connected in exactly the same manner and the pipes illustrated atM are connected to the water jacket of the engine in the usual mariner. Each of the sections D and E has a filling hole as shown in Fig. 2. The lower part of sections A and B are connected respectively to the sections D and E by a series of small horizontal tubes as shown in elevation Fig. 2 at P P. The water outlet from the radiator to the lower portion of the water jacket of'the engine, which is of the usual form, is shown at Q, but each receptacle D and\E is connected preferably by a separate. pipe at each side of the engine water jacket.

It results from this. construction that I have two independent systems each exactly construction that either one of these sections or systems composed of the receptacle A D or B E may be even removed by closing or capping the outlet and inlet .ports and the other system may be retained or kept in and Q are duplicates and that the two sec tions A and D or B and E are alike in their features of construction and mode of oper ation. To describe each of them separately is unnecessary and it is considered that the indicating letters refer to duplicate parts ex cept where otherwise described.

lhe mode of operation of this devlce taken as a whole is very similar to the ordinary action of the thermosiphon systems, though forcing means might be employed in the shape of pumps or other devices which however form no part of my invention and l do not deem it necessary to describe them.

The mode of operation of this device is quite apparent from. the foregoing description but it is sufficient to say that the air being concentrated and driven through the conical perforations L L strikes the flat surfaces adjacent thereto of D and E, is baiiied and spread around said surface through the opening J and between the receptacles D and E and the hood thereby creating a very efficient radiating .or cooling system. The opening N being restricted or choked the heated water in rising through the pipe M will be compelled rise to a higher level in the sections A and B. This also would take place if the sections D and E are filled completely or the flow therein is restricted by compressed air or steam in the top thereof. An outlet is provided in the sections A and B at S whereby if the temperature of the water becomes high enough visible steam will escape and this outlet may be carried above the hood if desired and become an indication of overheating. As the circulation in a thermosiphon system is well known it is unnecessary to describe the operation further. The sections D and E in the arrangement are lower than the sections A and B as .will be noted in Fig. 2. A projection T from the bottom of D and E as it were scoops the air and passes it past the connecting pipe P P which air passes through the space J and around the sections D and E at the openings F and G. Arrows indicatethe direction of the air currents. While I have shown but two systems it is obvious that by appropriate connections I may make morethan two.

What l claim is:

1. In a cooling apparatus for automobile engines, two rectangular radiator sections,

65,,each being adapted to form a part of a sep'a ll ,eeaese rate water cooling system, said sections being adapted to be removably connected with contiguous edges to form a single radiator.

2. In a water cooling apparatus for automobile engines, the combination of a front receptacle having conical air passages therethrough, the smaller ends of said passages being rearwardly arranged, a second receptacle located at the rear of the firstnamed receptacle with an air passage intervening therebetween, said second receptacle presenting a cooling surface in the line of flow of air passing through said passages, and adapted to permit the passage of air at one side of said cooling surface.

lln 'a water cooling apparatus for automobile engines, the combination of a front receptacle having conical air passages therethrough, the smaller ends of said passages being rearwardly arranged, a second receptacle located at the rear of the first-named receptacle with an air passage intervening therebetween, said second receptacle presenting a cooling surface in the line of flow of air passing through said passages, and adapted to permit the pamage of air at one side of said cooling surface, said first and second receptacles being so connected that the Water shall circulate through both receptacles.

e. llh a water cooling apparatus for automobile engines, the combination of afront receptacle having conical air passages therethrough, the smaller ends of said passages being rearwardly arranged, a second receptacle located at the rear of the first-named receptacle with an air passage intervening forcing a current of air through the interveninlg space between said receptacles.

5. n a water cooling apparatus for auto mobile engines, the combination of-a front receptacle having conical air passages therethrough, the smaller ends of said passages being rearwardly arranged, a second receptacle located at the rear of the firstnamed receptacle with an air passage intervening therebetween, said second receptacle presenting a cooling surface in the line of flow of air passing through said passages, and adapted to permit the passage of air at one side of said cooling surface, and means for forcing a current of air through the intervening space between said receptacles, a plurality of passages forming communications between said receptacles and presenting cooling surfaces in said intervening space.

In testimony whereof I sign this specification.
