biles and, particularly, to radiators for internal combustion engines.

This invention also relates to a novel 'arrangement of radiator or condenser, fan and hood on the frame or chassis of automobiles.

Among the objects of our invention may be noted the following: to provide an arrangement and disposition of the hood, radiator and fan which will protect the radiator and increase its efliciency; to provide an arrangement and construction of the hood and radiator which will protect the motor and render it readily accessible from all points and not detract from the efliciency of the radiator; to provide means by which the air may be drawn into the face of the radiator and exhausted from the latter practically in all directions; and to provide means by which the radiator can be prevented from becoming overheated.

VVit'h the above objects in View, and others which will'be detailed during the course of this description, our invention consists in the parts, features, elements and combinations of elements, all as hereinafter described and claimed.

In order that our invention may be clearly understood, the accompanying drawings are provided in which:

Figure 1 is a partial elevation and longitudinal, vertical section of therforw'ard end of the frame or chassis of an automobile having our invention ap lied thereto; Fig. 2 is a perspective view il ustrating the dashboard, side-bars and radiator, according to our invention; Fig. 3 is a view similar to r Fig. 1 showing a portion of the hood in side elevation; Fig. 4 is a vertical, transverse section taken on the line 4-4 of Fig. 3; and Fig. 5 is a section taken on the line 5-5 of Fig. 3.

Referring to the drawings, the numeral 1 indicates the side-bars of the frame or chassis of an automobile; 2 the "dashboard of the ear; and 3 the motor, which is supported in the usual izr'ianne'r upon the frame 7 1, the motor being shown in outline merely and without reference to'detai-ls, since it may do be of anyapproved type. In the form shown in 1 anti 2, the hb'od i, which covers the motor, is hinged at 5 to the faceplate 6 of the radiator-frame above its radia tihg section 7, the said radiator being $5 thus arranged between the rear end of the hood and the froiit of the dash-board 2 and seci'ired to the latter by -means of the side and top flanges '8, Which-are provided with a series of a'perturesthrou'gh which and the ("49 dash-board bolts 9 are passed to fasten it firmly to the "latter, the radiator settin at its bottom on the opposite side-bars i o the frame-to which it is'a'lso securely bolted. At its forward end, the hood may be secured 7 or latched *to the frame'in any usual manner, so as to event it from rattling or being lifted, an in its -forward face is provided with a door or gate composed of a rectang'ulajr frame 10, provided with a screen 11, w and hinged at its'bot-tom, as at 12, near the lower edge of the front end of the hood, a lock'orr latch iabeing' provided to secure the same against accidental opening or to prevent any one from opening it without a key. 83 As shown in Figs. 1 and 2, the hoodextends vertically from the'frar'ne of the car to near the top of the radiator and laterally covers a large portion of the tubing of said radiator. This feature is shown articularly in M Fig. 2, where theou'tl'ine oft e hood is represented by dotted lines. Thus, outside of the'fram'e of the hood, large volumes of air can be drawn 'intothe face of the radiator at opposite sides, while a very large volume of air can be drawn in through the screen 11 at the front end/of the hood and around the motor, thus rendering efiective the entire face of the radiating section of the radiator. We desire to lay particular stress upon the 3m disposition of the radiator in the rear of the hood and remote from the front end of the car since it gives great protection. to the radiator, which is a comparatively delicate and expensive element of the car. Further- 1% more, this arrangement gives symmetry and an es'thetic appearance to the car, which is very desirable. I

The radiator, fin'its eneral features, may be of any usual form, though we prefer that w form which is illustrated in our application' Serial No. 491,301, filed April 21, 1909.

The radiator, according to our present in-- vention, will have the top'portion 14 of its frame extended rearwardly quite a distance beyond its side frame-portions 15 and the radiating section 7, as clearly shown in Fig. 1; and, corresponding 'to this frame extension 14, the opposite sidesof the frame of the radiator are provided with the screensections 16, which leave the frame of the radiator practically open' at both sides in' rear of its radiating-section. Ihis struc: ture of the frame provides a large chamber 17 betweenv the dash-board 2 and the radiating-section 7, anfilfbetween the frame-- the side-bars 1 of the chassis. Furthermore,

the dash-board 2 is cut out at its bottom across substantially its. entire width, so as to provide the passage 20 at the, back of the chamber 17, near its bottom, which communicates with the space 21, under the footbo-ard 2 2 of the car, thus continuing the' chamber 17 through the dash-boardand under the foot-board. No bottompiece .is provided in the space 19, between the side-bars of the chassis directly under the foot-board 22 and dash-board 2, thus allowing the air drawn into the radiator by the'fan 23 to pass and to be forced through the chamber 17 into the space21 and down through the bottom of the car under the foot-board 22,

as well as down through the bottom of-the chamber through the space 19, and laterally through the screen 16 in the opposite sides of the radiator, and also through the aper tures 18 in the top part 14 of the radiatorframe. The fan may be of any usual construction suitable for the purpose of drawing air into the chamber 17 through the face of the radiator and at the same. time acting to drive or-force the air from said chamber all around, as just described. The fan preferably is located within the chamber 17, directly behind the radiating-section 7, andis journaled at 24 to the dash-board. The fanframe is provided with the pulley-extension 25, around which runs the belt 26, which latter is driven in usual manner by the drivewheel 27 ofthe motor, or by any other available mechanism of the car. At this point, we desire to lay stress upon the general arrangement and combination of parts just described, in that it is an important featureof our invention to provide the chamber 17 in rear of the radiator and have the fan located in said chamber. directly behind the radiating-section, so as to enable the fan to latter and the dash-board.

provide a powerful exhaust through said tubing and operate to powerfully drive the air thus drawn into the chamber 17 from the latter in all directions. It is to be understood, however, that the disposition of the fan-pulley shown is not to be taken as essential, for said pulley could be disposed at the back of the fanso' as to be between the Preferably, the screen-sections 16 are made removable, the means shown in this instance being lugs 28 on theside-bars 1 of the frame of the car for confining the lower end of the screen-section, and a latch 29 at the top for holding the upper end of the screen-section firmly in place. By swinging the latch away from the screen-section 16, it can be readily lifted from the confining lugs 28. No stress is laid upon the'particular means for rendering the screen-sections removable, thou h importance is attachedto the removability of said sections, since it enables ready accessto the fan and to the radiator in case of accident, or if for any purpose it is desired to gain access to the chamber 17.

In the form of our invention shown in Figs. 3, 4and 5, the hood 4 is made with an inner casing 30, which, in form, may or may not conform to the outline of the enginecylinders and inlet-pipes, this casing being connected at 31 to the hood 4, near its hinged end, and at its lower end is secured all around to the lower edge of. the hood, thus providing between the hood and the casing a chamber 32. By thus constructing-the hood, the same is made double, and upon this feature of our invention we desire to lay stress, since its importance lies in the fact that the hood 4 can be made of substantially any shape desired for ornamental purposes and with a view to giving symmetry and esthetie form to the car at its forward end,.

and can also be provided with openings of any character desired at front and s1des calculated to freely admit air in large volume for transmission to the radiating-sectionof the radiator. This structure has .a great advantagefalso in that a sealed-hood-eifect isobtained, in combination'with an open-hood effect, since it is quite desirable to prevent sand, grit, dust, water, or other substances from reaching the cylinders of the motor, or other parts thereof, and it is also essential to admit 'as much air to the hood as possible, in order to supply the required great volume of air for cooling purposes. Furthermore,-

by providing the inner sealed-hood, the outer hood can. be provided with all kinds of openings or air-flues, such as the screen 11 and air-inlets, and the elongated, vertical slots 33, in rear of each of which a fin 34 may be provided, which will effectively catch and shunt the air into the chamber 32, thus increasing the volume of air passing 50 't ant since 'repairs .10 the-contour of the outer-hood or-the contour of the motor,:'-andi-in -either case the inotoi chamberis made as largea'spossible and the hood-chamber as narrow as possible. (Dbviously, when 'itiis desired to inspect 5 the -motor, -or' get--atthe mechanism underv the hood, the latter-can be lifted and, in the dorm-shown in Figs. 3,-'-4-.- and 5, the inner -'-sealed-hoodwill be liftedat the same time,

since the-outer and the innerhoods are conneoted= together. :This is exceedingly important since, when it is necessary to mspect or examine themotor, =it should be possible to gain access to every part from every side. This is oss'ible in-ourconstruction oiraccount-o :placing' the radiator in-rear of the-hood-as'described. "Theinner sealed-hood prevents the :dust, dirt, grit, sand'and rain :Erom reaching the cylinders, or any operative parts of themotor-and, in

consequence, the latter-will bekept perfectly clean-and the usual wearsan'd tear on it will be eliminated. *By providing the inner -sealed 'hoodas described, the -usual fins 'or -shutters, which,:guard' the side openings -in the outer 'hood,'ean be omitted, since-rain,

dust,--etc., 'cannotareach 'the; motor but will pass through the chamber 32 and the radiator and be ejected frommthebottom of the car and the sides and-top ofthe radiator.

. From the foregoing description, it will =be seen' that the following arenamong the advantages -of our invention: The radiator is completely protected from all possibility -ofaccidental damage, since itis so far-back i rom the-front ofthe-carasto eliminate all chance-of vehicles striking the same, or-0f its'being injured ifthe car should strike obstructions of any kind, or moving objects-of any character, this being importo-radiators are usually 'very-expensive:and accidents to the radiator-are liable to put itand the car out of commission. :The disposition shown of the radiator also places it back of the motor and makes the latter much more accessible 'from every point=when neoessaryto'work on it for any purpose. 'This is exceedingly important-since it-enables thorough examinationand quickrepairs. By disposing the so radiator as shown, in combination with a hoodsuch-as shown, the range vof vision of the operator or driver of the car is very much increased, since the road ahead close to the front of the vehicle is clearly in sight as and-enables small objects to be qu ckly seen mas -- andvavoided. iTltiS' is especially important when the -caris going at high s eed-and sma ll objects are not readily discernible until thecaris almost .upon them, and often -cannotw be-seen at all when the car has a high projection-such as made by the radiator placed at the front end of the'car in the iline ot vision. By placing the fandirectly 1 behind the radiating-section, the aircan be drawn-in freely through said section andoquiclely forced out-of the top, sides and bottom, thus quickly disposing of the hot "airaand increasing the cooling wefliciency of the radiator. By making" the-hood double,

Hit is also considerably strengthened and Ten-('80 deredi much-more rigid than a single hood, thus. avoiding. warpingi and springing of the side and ends and maintaining it always in good condition and capable of being fas- -=tened :down: tight to insure the engine from-, 5 grit, dustyetc. We desirefiit understood, however, that we ,do not. purpose limiting our invention to any. particular .form of radiating-section, as it is with-in the scope ofour invention to employ anyform of-. radiator-tubing ifound efficient and practicable for the purpose. Nor do we purpose confining-our invention to the disposition of the fan in thechamber in rear of the tub- .zing,zithough-this disposition is preferable,-. since the fan could be placed in front of the tubing in the hood-chamber and so -formed as to force the-air through .the tubing. Moreover, we do not purpose limiting our invention to driving the air from thet o =ichamber 17 through the sides, top, bottom *and back, as illustrated: and described, since "there-may be forms of cars necessitating thezelimination of some of the outlets and restricting the exhaust to the sides or the top, or the bottom, or the back, or any two or more ways. of forcing the airfrom the -:chamber.
