Description

GYROSCOPI C VACUUM ENGINE Filed March 8, 1963 United States Patent Henry This invention relates to a crankcase vacuum-making device, and more particularly to an improvement for use with an engine having movable parts, including a vacuum case enclosing the moving parts and a vacuum-making device for removing the air, dust and waste fluids from the vacuum case.
The primary objects of this invention are to put all the moving parts to work in a vacuum; to avoid the useless beating of air, metal, oil, fumes, gases and other fluids; to prevent the useless wear and tea-r on moving parts that all retarding fluids and matter cause when flowing around the working parts of the machines; to reduce the cost of investment and operation; and to provide means for eliminating at least a substantial amount of the friction that is created in a crankcase.
In general, this invention comprises a vacuum-producing device inside an airtight case or pan, or other container, placed around the moving parts of an engine or machine, such as an internal combustion engine, in combination with a second vacuum-producing device and cleaner arranged outside the engine case, e.g., crankcase. The vacuum-producing devices are cleaners in the sense that they draw the dust, air, oil, fumes and other fluids from the case to prolong the life of the engine, accomplish new smoothness, quietness and ease of operation, avoid wear and tear on moving parts, and increase the power, speed and efliciency of the engine. More specifically, when used in an internal combustion engine, this invention comprises an airtight pan around the moving parts, i.e., crankcase, which contains a fan, a geared pump, a meshed lobe blower, a paddle wheel blower, and a piston and cylinder pump, all arranged to take power from the engine and expel the air, fumes, etc., from the pan to the atmosphere, vacuum device or cleaner when the engine is working.
These and other objects of this invention will become more apparent from the following detailed description takent in conjunction with the accompanying drawing in which:
FIGURE 1 is a schematic elevational view of an internal combustion engine including vacuum-producing devices arranged in accordance with this invention;
FIGURE 2 is a frontal view of FIGURE 1 illustrating the exhaust vacuum-producing device;
FIGURE 3 is a partial cross-sectional view illustrating one of the vacuum-producing devices of FIGURE 1;
FIGURE 4 is a partial cross-sectional view illustrating another of the vacuum-producing devices of FIGURE 1; and
FIGURE 5 is a partial cross-sectional view illustrating even another of the vacuum-producing devices of FIG- URE 1.
Referring to the drawing in more detail, and representing briefly all kinds of engines, FIGURE 1 schematically illustrates a cylinder-piston assembly, generally designated by numeral 10, in an internal combustion engine, arranged to be actuated in a conventional manner by combustion of a fuel .in chamber A by means (not shown) and to provide the driving force for crankshaft 12 through the connecting rod 14 which joins the piston 16 in cylinder 18 to the crank 20 on crankshaft 12. Crankshaft 12 is surrounded by crankcase 22 which is designed to seal the crankshaft 12 and assembly from the atmosphere outside the engine, and cooperate with the devices of this invention in maintaining a vacuum around assembly 10.
ice
The devices for maintaining a vacuum in accordance with this invention are connected to and operated by crankshaft 12 and include a pair of fans 24 and 25 arranged in casings 34 and 35, respectively, attached to crankcase 22 and forming openings B and C. Fans 24 and 25 are driven by gears 26 and 27 mounted on their respective axles 28 and 29 and gears 26 and 27 are driven by gear wheel 30 which is attached to crankshaft 12, e.g., by a lock and key. The fan axles 28 and 29 are supported in casings 34 and 35, i.e., openings B and C, by mounts 32 and 33, respectively. The three lobe wheel blowers driven by crankshaft 12 include a driving wheel 36 attached to an axle 38, and a driven Wheel 37 supported in journals (not shown) in casing 39 and 40. Air is drawn into the lobed wheel blower through opening 41 in the casing and expelled through passage 42. A paddle wheel fan, shown as including two paddles 43, is also supported on axle 38. Casing 45 which encloses paddles 43 includes inlets 44 and outlets 46 for removal of air from crankcase 22 through channels 47 to channel 69. Axle 38 is driven from the crankshaft 12 by sprocket wheel 48 which is attached thereto and chain 49 which is driven by sprocket wheel 50. Sprocket wheel 51) is attached to and driven by crankshaft 12.
A gear wheel pump formed by intermeshed gear wheels 52 and 53 is also arranged in crankcase 22 and driven from crankshaft 12. The gear wheels 52 and 53 are supported in journals (not shown), respectively, in frames 54 and 55. The larger gear wheel 52 is driven by pulley 58 locked to crankshaft 12 and belt 57 which drives pulley 56 attached to the axle of wheel 52. Air is drawn into the gear wheel pump through opening 59 in casing 54 and expelled through passage 60. The piston-cylinder pump assembly, generally designated as 62, is also connected by .rod 67 to crankshaft 12 by crank 68 so as to be driven thereby and remove air from crankcase 22. Air is sucked into the cylinder 63 of the assembly through valve 64 and expelled by piston 65 through valve 66. The various vacuum producing devices described are not intended to be exclusive .in nature, form, shape, size or arrangement since a device that will make a vacuum around the working parts of an engine, as schematically shown by piston-cylinder assembly 10, may be considered a vacuum-making device within the spirit and scope of this invention. Also, one or more of the illustrated and described vacuum-making devices may be omitted within the scope of the invention.
In operation, the apparatus functions to expel or draw out the gases and other fluids from the crankcase. Power is supplied to the individual vacuum-producing devices by, for example, combustion of a fuel in piston-cylinder assembly 10 although the cylinder can be converted to use other pressure fluids such as water. Air can be supplied to, and combustion gases removed from, the internal combustion cylinder chamber A in a conventional manner through valves 17 and 19, respectively. Plate means 21 .is arranged in engine block head 61 to support the valves for piston-cylinder assemblies 16 and 62. The two fans 24 and 25 draw gases and dust from the crank case 22 through openings B and C. The lobed wheel blower which includes wheels 36 and 37 with three lobes each, in revolving, draws gases up from crankcase 22 and forces the gases through passage 42 into the channel 69 (see FIGURES 1 and 3), formed in crankcase 22 by plate means 23. The gases to be expelled from the crankcase pass through channel 69. The arrows in the drawing show the course taken by the air. Paddle wheel fan depicted in FIGURE 4 with two vanes or paddles 43 which revolve inside casing 45 also expel-s air from the crankcase 22 into passage 69, i.e., through channel 47. As stated above, the paddle fan and the lobed wheel blower are driven through a single axle 38. Revolving snugly in casing 45, the vanes 43 expel any dust or fluid in the case out through apertures 46 and into channels 47 leading to channel 69. The arrows in FIGURE 4 show the air flow. The gear pump which includes two intermeshed toothed Wheels 52 and 53 inside casings 54 and 55 formfitting with the gear wheels for proper suction draws air, or other fluids, in through aperture 59 in the lower edge of casing 54 and forces the air into channel 69 through passage 60 as shown by the arrows in FIGURE 5. The revolving wheels 52 and 53 draw fluid in at the bottom of casing 54, carry it around with the wheels and force it out at the top into passage 69. Piston-cylinder assembly 62 sucks air, gases, dust, fluids, fumes and other waste matter out of channel 11 in through valve 64 and ex-pels them through valve 66 into channel 69 to provide added impetus to the flow of fluids in channel 69 where the output of all the vacuum-making devices in crankcase 22 is carried to the atmosphere. Crankshaft 12 is supported in crankcase 22, for example, by journals and supports 70.
