Description
- The present invention relates generally to a mechanism to provide a rotating/angular oscillating output.
- A slider crank mechanism is well known in the art and provides a viable means of producing rotating output from a reciprocating motion or vice versa. In
FIG. 1 , a conventional slidercrank mechanism system 101 is shown.System 101 includes apiston 103,crank shaft 105, and connectingrod 107. The most conventional usage of the said mechanism is in an internal combustion engine. - As depicted in
System 101, thepiston 103 moves in a linear direction which is typically guided by acylinder 109. As thepiston 103 reciprocates, linear motion is converted into rotary motion through the connectingrod 107 andcrank shaft 105. The mechanical efficiency of the mechanism is severely affected due to change in the movement pattern (from reciprocation to rotation or vice versa). - Several mechanisms, such as the one presented above, are utilized to obtain a rotating output for the use in prime movers or power generation purposes. Obtaining a more compact mechanism with higher efficiency and lesser mechanical losses is an essential and driving factor for this invention.
- The novel features believed characteristic of the embodiments of the present application are set forth in the appended claims. However, the embodiments themselves, as well as a preferred mode of use, and further objectives and advantages thereof, will best be understood by reference to the following detailed description when read in conjunction with the accompanying drawings, wherein:

Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
- The system and method of use in accordance with the present application overcomes one or more of the above-discussed problems commonly associated with conventional mechanisms of providing rotating output from a reciprocating motion. Specifically, the system of the present application provides a new and useful mechanism; namely, a butterfly mechanism, which can be used in internal combustion engines and the like. These and other unique features of the system and method of use are discussed below and illustrated in the accompanying drawings.
- The system and method of use will be understood, both as to its structure and operation, from the accompanying drawings, taken in conjunction with the accompanying description. Several embodiments of the system are presented herein. It should be understood that various components, parts, and features of the different embodiments may be combined together and/or interchanged with one another, all of which are within the scope of the present application, even though not all variations and particular embodiments are shown in the drawings. It should also be understood that the mixing and matching of features, elements, and/or functions between various embodiments is expressly contemplated herein so that one of ordinary skill in the art would appreciate from this disclosure that the features, elements, and/or functions of one embodiment may be incorporated into another embodiment as appropriate, unless described otherwise.
- The preferred embodiment herein described is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described to explain the principles of the invention and its application and practical use to enable others skilled in the art to follow its teachings.
- Referring now to the drawings wherein like reference characters identify corresponding or similar elements throughout the several views,
FIGS. 2A & 2B depict asystem 201 using a butterfly mechanism in accordance with a preferred embodiment of the present application. It will be appreciated that thesystem 201 with the butterfly mechanism overcomes one or more of the commonly associated problems of conventional mechanisms. - In a preferred embodiment,
system 201 includessnitches 205 & 207 which rotate inhousing 203. In some embodiments, the system can include one or more pairs ofspark plugs 209 andfuel injectors 211 to be fixably mounted to theengine housing 203 which provide fuel and ignition, respectively. It is contemplated that seals will be used between thehousing 203 andsnitches 205 & 207 to provide for a closed chamber and smoother movement of the snitches. It should be appreciated that the invention disclosed herein includes the mechanism created by the snitches, as discussed. This mechanism can be incorporated into an internal combustion engine, or utilized for other means, while keeping the same integrity of the mechanism. - It is appreciated that the
snitches 205 & 207 contain a protruding tab on their outer diameters which creates the closed chambers. It is also appreciated thatsnitches - Referring now to
FIGS. 3A & 3B , section views ofsystem 201 are shown which depict the operation ofsystem 201. Thesnitches 205 & 207 have a bevel gear arrangement inside so as to allow the motion of both the snitches simultaneously in opposite directions. Thisbevel gear arrangement 305 & 311 is similar to the one found in the differential of an automobile. This arrangement can be replaced with some other arrangement; however, the idea is still the same so as to force both snitches to move in opposite directions. A ratchet & pawl mechanism 313 (similar to the one found in bicycles) is incorporated inside the bevel gears. This mechanism is coupled to the output shaft and helps in rotating it only in one direction. During the operation, the snitches move in opposite directions to each other all the time. Hence, in order to provide the movement of the output shaft in only one direction this ratchet andpawl mechanism 313 comes in help. This ratchet and pawl mechanism can be replaced with some other arrangement such as a sprag clutch; however the idea is still the same so as to allow the movement of shaft in only one direction while snitches can move in either directions. - One of the ways of using this mechanism is to utilize this as an internal combustion engine. Each chamber created between the wings of the snitches can act as a combustion chamber. As the fuel in
combustion chambers 303 is ignited by spark plugs, the combustion forces cause thesnitches snitches pawl mechanism 313 to theoutput shaft 307. It should be noted that both the snitches are moving in opposite directions. However, theoutput shaft 307 only rotates in one direction due to the ratchet andpawl mechanism 313. This is viewed as an advantage of the system of the present application. Another method is to have a magnetic repulsion or attraction between the wings and hence cause the to-and-fro movement. Another method is to use just compressed fluid in timely manner to allow movement of the snitches and hence a rotating output. - In
FIG. 3A , an example of use of the mechanism described herein is shown. As shown, one ormore combustion chambers 301 are shown containing fuel which was inserted byfuel injectors 211. As the fuel incombustion chambers 303 is ignited by the spark plugs 209, the combustion forces cause thesnitches snitches pawl mechanism 313 to theoutput shaft 307. It should be noted that both the snitches are moving in opposite directions. However, theoutput shaft 307 only rotates in one direction due to the ratchet andpawl mechanism 313. This is viewed as an advantage of the system of the present application. - In
FIG. 3B , one or moredifferent combustion chambers 303 are shown containing fuel which was inserted byfuel injectors 211. As the fuel incombustion chambers 303 is ignited by the spark plugs 209, the combustion forces cause thepistons snitches 205 & 207 back to their original position is transmitted through the bevel gears and the ratchet andpawl mechanism 313 to theoutput shaft 307. It should be noted that both the snitches are moving in opposite directions. However, theoutput shaft 307 only rotates in one direction due to the ratchet andpawl mechanism 313. As thesnitches 205 & 207 are back in their original position the exhaust gases shall be vented out from the valves and fresh air-fuel mixture shall be injected inside. This shall cause the snitches to move back in opposite directions again. Similar exhaust and intake shall be carried out in the other two chambers shown. In this way the snitches shall keep moving in opposite directions creating combustions chambers between them and causing the output shaft to move in one direction only due to the ratchet andpawl mechanism 313.System 201 is referred to as a butterfly engine since thesnitches 205 & 207 reciprocate back and forth like butterfly wings. - The present invention includes the following features in alternative embodiments. The mechanism embodiment has a casing which comprises of 4 chambers created using snitches. The shape and design of the snitches is given as per the Figures. The ratchet and pawl mechanism is not a strict and any mechanism that can perform the job of ratchet and pawl shall be fine (for example a sprag clutch).
- Further, the present invention includes the following features in alternative embodiments. The bevel gear mechanism helps in transmitting the motion of one snitch to the other. Any other mechanism that does the same work is also acceptable and contemplated herein. A mechanism to aid in conservation of angular momentum can also be included in the embodiment (not included in this design but can be incorporated in several ways). The addition of spark plugs, injectors, valves etc. can be varied based on the requirement of the embodiment.
- It is contemplated that a mechanism for conserving the angular momentum of the snitches also can be included. Although this mechanism is not covered herein, an equivalent mechanism apparent to those skilled in the art having the benefit of the teaching herein can be included.
- The particular embodiments disclosed above are illustrative only, as the embodiments may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. Although the present embodiments are shown above, they are not limited to just these embodiments, but are amenable to various changes and modifications without departing from the spirit thereof.
