; Referring to the accompanying draw- Figure 1-, somewhat diagrammatically illustrates the front portionof a motor vehicleshowing the fancasing of my invention mounted on the frame and connected to deliver cooling air to the motor cyfinder jackets, the hood being removed to show the motor.
Fig. 2, is a detail perspective view of the fan casin and fan,
Fig. 3, 1s a section on the line 33, Fig. 2.
In the drawings, I show the longitudinal beams 1 of a motor vehicle frame or cha$is, and the motor 2. This motor is of any suitable or ordinary internal combustion or ex plosive type, the cylinders of which are pro- ,vided with the usual or any suitablejackets for the passage of cooling medium. In the ordinary Water cooling system, an upright Water cooling radiator is fixed to the frame beams and pipe connections extend therefrom to manifolds or-other water passages leading to and from the water jackets sur- I'Ounding the cylinders so as to provide a continuous flow of water-in circuit including the radiator and cylinder cooling jackets as is well understood by those skilled in the art. These water cooling systems also provide a fan between the motor and radiator and driven from the engine or motor shaft to increase the radiation of heat from the radiator and hence aid in reducing the temperature, of the water therein. According to my invention, I dispense with the cooling water, the water-radiator, the fan behind the same, one of the pipe connections from the cylinder jackets to the radiator, and the water.
ing at the bottom or lower part of the motor through which water flowed in the water cooling system.
In the specific example illustrated, the fan )r blower box or casing 7 is constructed to nore or less closely approximate the exterior shape or appearance of the ordinary water cooling radiator. This casing is strongly constructed of sheet metal and is formed at its lower corners with flanges or 8 to fit the frame beams of the motor lu s vehicle and be bolted or otherwise fixed thereto, although I do not wish to so limit my invention. In fact, the blower casing 7 is ordinarily secured to the frame beams at the usual'location of and in approximately the same way as the ordinary water cooling radiator, and is arranged and of about the same shape and dimensions as the water cooling radiator, and if so desired 'can'have a brace, such as9, applied to .its upper portion as is more or 1cm common practice in mounting the water radiator. The fan casing 7 hence extends transversely across the motor vehicle frame and is fixed to the two framebeams and rises vertically therefrom. The fan casing is closed at its bottom, opposite side and top edges by usually 1mper- .forate lates or walls 10, while the vertical 4 rear .si e of the casing'is formed by plate 1 or wall 11, having a reduced central air in-- I lower let opening 12, and the vertical front side wall of the casing is more or less open for the passage of air and embodies a. vertical protective screen 13, preferably of-such degree of fineness as to approximately prevent passage of dirt and dust to the fan within thecasing. v i
Withinthe fan casing I provide any suitable rotor designed to maintain a flow of air for cooling the motor cylinders by passage-through the cylinder jackets or otherwise. In the parti'cularexample illustrated, I show the fan casing connected up to supply this flow of coolin air to the motor cylinder jackets, through t e medium of air. pipe 14 at its front end coupled to air outlet 15, at the upper part of the rear wall of the casing, and at its rear end coupled to the manifold .16 at the. upper part of the motor and delivering air to the cylinder jackets so that the heated air will discharge from the motor through outlet or discharge port 17 at the part thereof, although I do not wish toso limit all features of my invention.
The casing air discharge port or nipple 15, opens into the rear end of an air pocket or pressure chamber a formed within the top portion of the fan casing between the front,
rear and'top walls thereof by an approximately L-shaped partition18, secured to said.
walls and providing the pressure chamber or pocket with an open side or inlet 6 located at the front of the the direction of rotation of the fanyrotor.
In the particular example illustrated, the
rotor approximately fully occupies .the interior of the fan casing and comprises parallel flat vertical 'front. and rear circular side walls 19 having alined central 0 enings and radial arms 20 fixed tosaid si e walls and to a central fan shaft 21, and uniformly- .fan rotor at the desire I show driving chain or belt 26 from or driven bythe motor shaft, applied to said pocket with respect to spaced radial flat fan blades 22 extending between and fixed to said walls 19 and in width radially of the rotor usually approximately equal to the radial width of the rotor si e walls.
The fan rotor is supported and driven by the fan shaft 21 and said shaft is mounted in and supported by arms or brackets 24 fixed to and supported by the front and rear walls of the fan casing. The rear end of the fan shaft is extended rearwardlyjto the exterior of the casing and is provided with pinion or pulley 25, or other suitable means, for the application of power for rotating the speed. For instance,
pinion 25. for driving the fan.- The driving belt 26 is. usually the same means utilized to drive the fan employed in connection with theordinary water cooling stems, although I do not wish to so limit all features of my invention.
The air pocket or chamber in the upper part of the casing, 'is so arranged with re spect to 'the centrifugal fan-rotor, that the outer edges of the fan blades more or less closely sweep the under side of the bottom wall of said pocket, and'said pocket will receive the air thrown from and rotating with each blade as it sweeps past the open side of the pocket and air pressure will hencebe maintained in said pocket. a
The rotor when in action will throw air centrifugally from its blades and hence will cause the body of air around the rotor to r0- tate therewith and will maintain this body of. rotating air under more or less prmsure.
The air pocket is arranged across the path.
of rotation of this body of air and directly intercepts the same and hence the pressure in said pocket will cause a constant .outflow of air under pressure through outlet 15 to and through the motor cylinder jackets for the-effective cooling of the motor cylinders.
My invention can be applied-to motor vehicles in the course of manufacture, but also can be readil applied to motor vehicles now in use an equipped with water cooling.
systems and radiators, as my fan casing can be"- readily substituted :for .the water cooling radiator as hereinbefore described.
It is evident that various changes, modifications and variations might beresorted to a fan casing having an air inlet and an upper air blast outlet connected to supply' a blast of cooling air to said inlet of the cooling system, a rotary air blast fan in said casing arranged to draw cool air through said casing inlet and force the same under pressure through said, top outlet of the casing.
2. An internal combustion motor having a cooling fluid circulating jacket system providedwith an upper cooling air inlet and a lower heated air exhaust, in combination with an upright fan casing fixed in front of said motor and simulating a motor-vehicle Water-cooling radiator, said casing having a central front air inlet and a top air discharge With an air blast pipe extending therefrom to said cooling air inlet, and a rotary air forcing fan in said casing.
3. In a motor vehicle engine cylinder cooling system, an upright fan casing in appearance and size approximately simulating the Water cooling radiator of the engine Water cooling system of such vehicle and constructed-and arranged to be substituted for and to be secured to the vehicle frame in place of such radiator, and having an air blast off-take connection constructed and arranged for coupling to the engine cooling therefrom to the engine cooling Water pipe and jacket system, from which the Water has been drawn, to supply cooling air to the cylinder jacket, said engine having an air discharge from said jacket, and a fan rotor in said casing and operatively connected with and driven by the engine.
5. In air cooling-systems for jacketed motorcylinders, a fan rotor arranged to discharge air radially and to rotatively circulate the body of air around the rotor, and an uprightcasin for said rotor havin ternal air poc et open at its front side with respect to the direction of rotation of the an ini rotor and arranged to intercept said air rotating with the rotor, said pocket having a discharge to the exterior of the casing for receiving a pipe to convey the air to the motor.
6. In cooling systems for the internal combustion motors of motor vehicles, an upright fan casing having a front air inlet and a rear compressed air discharge, said casing in size and appearance approximately simulating the Water cooling radiator of a Water cooling system for said motor and being constructed and arranged to be fixed to the vehicle frame in the position ordinarily occupied by said radiator, a fan rotor in said casing, means for coupling the rotor to and driving the same from said motor, and means for coupling said air discharge to the cooling Water pipe and jacket system of the motor to maintain a flow of cooling air therethrough in the place of the cooling Water.
7 Air circulating apparatus for motor cylinder cooling systems, comprisin a fan casing having an air inlet and an mternal open-side air pocket with an end outlet to receive an off-take pipe connection, means for securing said casing in a fixed'upright position, and a fan rotor Within said casing provided With a shaft for driving connection With the motor, said rotor having vertical side walls with center openings and interposed radial fan blades, said air pocket arranged to intercept the body of air rotating with and around said rotor.
8. An air cooling system for internal combustion motors arranged to force cooling air through the jacket system of such motors, comprising an upright fan casing havinga closed surrounding edge Wall and side Walls with center openings, fixed arms bridging said openings, a fan shaft carried by and rotating in said arms and arranged to be driven by the motor, a fan of the inclosed centrifugal type arranged in said casing and carried and-driven by said shaft, said casing formed With internal means beyond the periphery of said fan to collect the air compressed by said f an, and-a pipe. connection to conduct the air blast from said means to the motor jacket system.
