To all lwhom it may lconcern Be itknown that l, JOHN C. CoL'rRIN, al

This `invention relates to radiators for use in connectionwith the cooling systems of internal combustion engines, and is adapted particularly for use upon motor vehicles.

The primary object of the invention is`to provide a radiator which shall be of simplified and improved construction, aund whereby theelticiency of such devices is generally increased'i y A furtherv object of the invention is to providea radiator having the usual water tubes, and wherein'the breakage of one or more of the tubes will not affect the operation of the radiator.

A still further 'object of the invention `is to provide avradiator of the character described which is capable of being readily attachedto and detached from thejvehicle and coupled to the cooling system ofthe engine thereof, which is provided with f tubes, which may be readily removed should it be desired to repair the same and without detaching the radiator in its entirety from the vehicle, which is provided with improved cooling and condensing means, which is adaptable to motor vehicles now in use, and' which is simple and inexpensive of construction and `maintenance, and which will prove thorou hly eicient vin the attainment-of the ends or which it is designed.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of arts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims. rllhe invention will be best understood 'by referring to the accompanying drawings, wherein Figure `1 is an elevation of a radiator constructed and arranged in accordance with the invention;

Fig. 2 is a transverse sectional View taken upon line 2-2of Fig. 1;` a Y Fig. 3 is a similar view taken `on line 3 3 of Fig. 1;

ylower face of the tank `of the radiator. A rearwardly 1- 1m Fig. 4 is a transverse sectional view taken upon line 4-4 of Fi 1; and

Fig. 5 is an enlarge sectional view taken throufgh one of the improved radiator tubes. Re erring now more particularly 'to the drawings, 6 indicates a base tank and 7 a head tank. These tanks are of substantiallyf the' same length and width, and are preferably rectangular in cross section, the said tanks being of la length to fit between the frame members of the motor vehicle at the forward end thereof. The base tank has its upper face provided with a plurality of spaced apertures, anda nipple 8V is arranged at the lower portion of the tank and at the rear thereof to be connected withthe cooling system of the motor vehicle engine. A drain cock 9 is also connected to the tank at the .basel thereof so that the contents of the radiator may be drawn'therefrom when desired.

Associated with a device of this character is a cap piece 11, the llatterbeing adapted to rest-upon and to communicate with the interior of the upper or head iece 7 of the radiator. The upper edges o the side and end portions ofthe head tank 7 are turned inwardly to provide Hanges 12,' upon which similarly formed flanges 13 at the lower ed es of the cap piece 11 rest. The front and rear or longitudinal walls' of the head tank 7 are connected by'tubes or air ducts 14, the same being arranged throughout the length ofthe said head tank to permit of air passing. freely throu h the same. The is provided with a plurality of apertures arranged in vrspaced relation and being disposed directly above the apertures in the upper face of the base tank 6.

rIhe front and rear walls of the cap piece 11 are connected by tubular members or air ducts 15, the same being arranged in spaced relation Vthroughout the extent of the cap piece and permit of air owing freely throughtothe rear portion of the said cap piece. disposed hrlzontally thereln, above the tubes 15 is a perforated diaphragm-16, the latter serving to evenly distrlbute the .water within the cap piece over the condensing or air tubes 15. The u per portion of `the ca e piece is'provided with aneck 17, throng which water may be poured to the interior nding Arran ed within the cap-piece and nipple 18 ris arranged upon the cap piece,

and by means of which the portion of the radiator is connected to the cooling system of the combustion engine. may be of any shape or size, so as to conform to the various types of motor vehicles with which the improved radiator is used. The base and head tanks 6 and 7 are provided at their upper and lower edges and at the ends thereof with outwardly projecting ears 19, the same being perforated, and being adapted to receive tie rods 20, the latter being of a length to connect the head and base tank and to maintain the same in spaced relation. The tie rods are provided inwardly from their upper and lower ends with enlarged portions 21, certain of the sa-id enlargements forming shoulders for the support of the head tank, while the others .rest upon the uppermost of the outwardly projecting ears 19 of the base tank to hold the latter properly spaced from the head tank. The extremities of tlie tie rods are threaded as shown, and binding nuts 22 may be arranged upon the said extremities to firmly bind the said tanks upon the rods. The lower portion of the cap piece 11 is also provided with laterally projecting lugs 23' to rest upon and overlie the uppermost of the ears 19 upon the head tank 7 and to relceive the upper ends of the tie rods 20.

Brackets 24 are provided for the purpose lof securing the improved radiator to the frame of a motor vehicle and the said brackets have -upright portions provided with outwardly extending perforated ears" 25 through which the lower ends of the tie rods extend, and the foot portions 26 of the 'brackets rest upon and are bolted as at 27 to' the longitudinal frame members of the' motor vehicle. The ears 25 upon the brackets are spaced apart preferably a distance to enable themselves to iit snugly between the spaced ears 1'9 upon the base tank 6.

From this construction, it will be seen .that the device may be readily assembled upon a motor vehicle by extending the lowerportions of the tie rods 20 through the alined

apertured ears

19 and 25 upon the base tank 6 and braclpts 24, and by engaging the ears of the ead tank and those of the cap piece with the upper portions of the tie rods. Tightening of the nuts 22 upon the tie rods will firmly bind the base tank 6 upon the brackets 24, and the head tank and cap piece upon the upper portions of the rods. The shouldered portions 21 of the tie rods maintain the upper and lower portions of the radiator in proper spaced relation.

A plurality of tubes 30 establish communication between the base and head tanks 6 and 7. These tubes may be formed of relatively small metallic pipes, and are The cap piece in the registering apertures in the upper and lower faces of the base and head tanks respectively. Each tube is provided adjacent its lower end With a shoulder portion 31, under which the gasket 32 is adapted to be positioned so that when the tubes 30 are forced downwardly upon the tank 6, the gaskets will make al water tight connection between the said tubes and tank. The exterior of the opposite end of each of the tubes 30 is threaded as shown, for the reception of a nut 33 and lock washer 34, and a gasket 35 is positioned between each of the washers and the end face of the tank 7 to prevent leakage at the joints between the tubes and the tank. From this construction, it isy apparent that upon -properly inserting the tubes in the alined apertures in the tanks 6 and 7, and screwing the nuts 33 upwardly so as' to bind the lock washers and gaskets against the bottom of the tank 7, a water tight connection will be formed between the tu es and the tanks 6 and 7. It is also obvious that any of the tubes may be removed when required for repair or renewal without disturbing any `of the remaining tubes or detaching the radiator from the vehicle. Should any of the tubes become broken or leaky, the-same may be detached and the openings in the base and head tanks soldered or in any other manner closed.

Arranged within each ofthe tubes 30 and preferably at the upper portion thereof is a reducing member 36. These reducing members restrict the openings in the tubes so that water passing downwardly therethrough will drip or flow-in a ine stream, whereby the same may be readily cooled. The reducing member also reinforces or strengthens the tube at its clamping end.

The vertically disposed tubes 30 are arranged between the base and head tanks in relatively' close relation so that cooling fluid may have free access to the 'lowertank, and as the vehicle` advances, air will contact the said tubes and cool the water within the same. By providing the air ducts or tubes 14 and 15 in the tanks 7 and 11, the water contained therein will be cooled more or less before entering the vertical tubes 30.

From the foregoing disclosure, it is apparent that I have provided an extremely simple, inexpensive and yet thorou hly eicient radiator for use in connectlon with combustion engines for cooling the liquid in the cooling systems thereof. The 'device may be readily attached and detached from the vehicle when required, and yet repairs of the various parts may be easily made without detaching the entire cooling device.

Vhile the above is a description of the preferred embodiment of the invention, it is obvious that various changes in the minor details of construction and arrangement of tank, a cap piece having its lower end open,

navman ma parts may be resorted to, without departing from the spirit of the invention or exceeding the scope of the claims.

What is claimed is l. In' a device of the 'class described, a pair of superimposed tanks, the said tanks being provided with vertically alined openings, tubes extending loosely at their ends into said openings to establish communication between said tanks, a shoulder projecting outwardly from each of said tubes at the lower end thereof, threads upon the upper ends of said tubes, nuts upon said threads, and gaskets between said shoulder and the 'lower tank and between said nuts and upper tank.

2. In a device of the class described, upper and lower tanks, pipes establishing cormnunication between said tanks, the upper tank having its upper end open, an inwardly projecting flange defining the open end of said anV inwardly projecting flange deiining said open end and being adapted to rest upon the flange of said upper tank, outwardly projecting apertured ears on said tanks and cap piece and the said ears having their apertures alined, rods extending through said apertures, and shoulders on said rods engaged' with said ears for maintaining said tanks in spaced relation.

3. lln a device of the class described, upper and lower tanks, pipes establishing communication between said tanks, outwardly' projecting ears at the upper and lower ends of said tanks, rods extending through said ears, shoulders adjacent the upper and lower ends of said rods engaged with said ears to maintain the said tanks in spaced relation, a cap piece resting on said upper tank, ears projecting outwardly from` said cap piece and resting upon the ears at the upper end of said upper tank, the said rods extending through said cap ears, and nuts on the ends of said rods.
