CORPORATION OF DELAWARE.
AIR-COOLING SYSTEM FOR INTERNAL-COMBUSTION ENGINES.
Application filed December 31, 1918.
1 0 all w hum. it may concem Be it known that I, Ansnnv H. Fox, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Air-Cooling Systems for Internal-Combustion Engines, of which the following is a specification.
This invention relates to means for cooling explosive engines, and is especially designed for use as an air cooling system for the internal combustion engines of motor vehicles.
The prime; object of the invention is to provide simple, economical, durable, novel and efiicient means for cooling by air a inulticylinder engine in which the cylinders are arranged in tandem, and by such means that the air at atmospheric temperature will be distributed to all of the cylinders at the same time so as to simultaneously have the same cooling effect thereon.
Another object of the invention is to provide means for maintaining the circulation of air past the engine at speed proportionate to the speed of the engine, so that, whether the vehicle be stationary or running, the movement of the air will continue, since my construction is such that I am able to take advantage of the motion of the vehicle to increase the volume of the cooling current of air.
A further object of the invention is to surround each cylinder of the engine with a split aluminum ring provided on its exterior surface with a series of spirally formed integral radiating fins extending the entire length of the ring, and surrounding the circumference, said ring possessing greater conductivity than the ordinary iron or other metal heretofore employed, and furnishing a greater area for contact with the cooling air currents, which ring is encircled by an outer air jacket.
The foregoing and such other objects as may appear from the ensuing description are attained by the novel features of construction, location and arrangement of the parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the claims appended hereto, it being understood that Specification of Letters Patent.
Patented Feb. 8, 1921.
Serial No. 269,085.
slight changes in the form, proportions, and minor details of the construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawings which form a part of the specification it will be seen that:
Figure l is a view showing partly in longitudinal section and partly in elevation the cooling device embodying my invention.
Fig. 2 is a transverse sectional view taken on the line 4-4 in the direction of the arrow, Fig. 1, showing the crank shaft casing and engine cylinder in elevation.
Fig. 3 is a plan view with the hood or casing removed from the engine.
Fig. 4 is a side elevation of my im roved device with the hood or casing secure in its normal position.
Fig. 5 is an enlarged transverse sectional view taken through one of the engine cylinders and the means surrounding each cylinder.
Fi 0 is a view! of the hood or casing broken away, showing in longitudinal section a portion of the said hood or casing and a plan of the interior.
Fig. 7 is an enlarged side elevation of the split aluminum ring which surrounds each engine cylinder.
ig. 8 is a front view of the engine hood or casing, and
Fig. 9 is an enlarged perspective view showing the air jacket detached from the en ine.
imilar numerals of reference are employed to designate corresponding arts throughout the several figures of the rawin s.
In carrying out 111 novel air cooling system for internal com ustion engines utilized in connection with motor vehicles, I em loy a removable hood 1, which is mounted in any suitable or desirable manner at the front end portion of the vehicle, and mounted upon the engine frame, or in any other convenient manner within said hood 1, is an auxiliary hood 2, which extends longitudinally beyond, both at the front and rear of the series of alined engine cylinders 3, said auxiliary hood forming an air chamber 4 around the upper portion of the crank shaft casing 5, which chamber communicates with the outlet 6 at the rear of said casing.
Surrounding each engine cylinder is a removable metallic ring 7, preferably made of aluminum, the periphery of which is provided with a series of spirally arranged longitudinal fins or ribs 8, which are integral with and project radially from the said ring at a uniform distance apart, thereby forming a series of air spaces entirely around the ring for the circulation of the air around each engine cylinder, and, since the aluminum metal possesses greater conductivity and the spirally arranged. fins or ribs furnish a greater area of contact with the air cooling medium, the uniform cooling of the engine cylinders by air is materially increased. Each of the said aluminum rings is split throughout its length at 9, in order that it may be easily sprung around the engine cylinder, each ring being surrounded by a detachable air jacket 10 made of sheet' extending ears 12, forming a series of air openings through the hood at the opposite sides of the engine cylinders, substantially throughout the length of the alinement of the series of engine cylinders, said ears being so arranged that the forward motion of the vehicle will force the air into the hood through said openings, thus causing the fresh air to be fed more evenly to all the air jackets around the cylinders than if the air entered at just one end of the hood, and which materially assists in producing the necessary cooling volume of air, since it will be readily apparent that when the vehicle is running in a forwardly direction, as indicated by the arrows shown in connection with Figs. 4: and 6, air will be caught by the projecting ends of ears and forced through the openings into the hood at each side of the series of engine cylinders thereby greatly increasing the volume of air which enters the hood, and the drafts thus created in connection with the screened front inlet opening keep said engine cylinders in properly cooled condition, and are augmented by the aluminum ring and its'iins or ribs, and a discharging suction fan 13 mounted on the rear end portion of the crank shaft 14:, which fan causes the volume of air within the hood to circulate through the air jackets in contact with the outer peripheral surface of each ring 7 and the spirally and radially formed aluminum fins or ribs 8 into the air chamber 4, and thence be discharged through the outlet 6, whereby a SllfllOleIlt cooling medium is created to main tain the cylinder in cooled condition and at a safe temperature. 7
While I have illustrated my novel air cooling system in connection with a fourcylinder engine, it will be obvious that this system may be readily applied to any particular type of multicylinder engines employed in connection with motor vehicles.
The operation may be briefly described as follows:
While the vehicle is in-motion a current of air is caused to pass through the screened front of the hood; at the same time air is forced through the openings formed by the deflecting ears 12, at each side of the hood, which will cause the cool fresh air to be fed evenly to all the air jackets around the cylinders and augmented by the-suction fan 13 will circulate and distribute the air in contact with the outer periphery of each aluminum ring 7, and its integral radiating fins or ribs 8, thence into the air chamber 1} formed by the auxiliary hood 2, and is dis charged through the outlet 6 at the'rear of said chamber, whereby all of the cylinders are simultaneously subjected to the cooling medium, and maintained at a safe tempera ture and in proper cooled condition.
It will be obvious from the foregoing description, considered in connection with the drawings, that a hood or casing as thus constructed affords simple means for cooling the entire series of engine cylinders at the same time, which means will not materially affect or detract fromthe appearance of the vehicle. 7
It will be-perceived that the fresh cool air admitted will also flow through the perforations formed through the air jackets 10, thereby materially assisting in maintaining the engine cylinders in cooled condition.
It will also be seen that the split aluminum radiating ring or sleeve 7 serves to allow for the difference and variation inexpansion and contraction caused by the heat between the cast ironengine cylinder and said radiating ring.
It will be further understood that the 11 hood 1 is not absolutely necessary, since-the engine will work as good without it, in the event that said hood should become damaged by collision or otherwise.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. An air cooling system for multicylinder engines of motor vehicles comprising a detachable split ring yieldingly surrounding each cylinder of the engine, saidring being provided with a series of radiating fins.
2. An air cooling system for multicylinder engines of motor vehicles comprising a removable split aluminum ring embracing each cylinder of the engine, said ring being provided with a series of integral spirally arran ed radiating fins.
in air cooling system of the character described comprising a detachable split aluminum ring surrounding each cylinder, said ring having a series of integral radiating fins spirally arranged throughout its entire length.
4. An air cooling system of the character described comprising a removable split resilient ring surrounding each cylinder adapted to allow for variation in expansion and contraction of heat, said ring being provided with a series of spirally arranged radiating fins extending throughout its length.
5. An air cooling system of the character described comprising a detachable split aluminum ring yieldingly surrounding each cylinder adapted to allow for difference and variation in expansion and contraction of heat between aluminum and cast iron, said ring having its outer periphery provided with a series of s irally arran ed radiati fins, and a detachable air jaclret provide with a series of staggered openings therethrough, said jacket surrounding said ring and fins.
