  • Patent number: 5910190
    Abstract: The transmission and clutch assembly including a conventional casing, a slidable input shaft directly engageable to the drive member for high gear, and further including an output shaft which is rotatably engaged in the open end of the input shaft, and further including a countershaft for change speed mode and reverse speed, a reverse speed shaft, a clutch housing, a clutch shaft connected to the clutch housing, a pair of pressure members, and a throw-out bearing for change speed mode including reverse speed. This transmission and clutch assembly does not use any internal oil pressure to effect changing of gears and substantially reduces the rotating weight of the transmission when the vehicle is in high gear, because the clutch housing, clutch shaft, input gear and pressure members do not rotate when the transmission is in direct drive speed mode unlike other known transmissions.

  • Patent number: 5902944
    Abstract: Finger-controlled members for contacting the strings on a guitar includes three string-contacting finger members, one for the index finger, one for the middle or second finger, and one for the third or ring finger. Each of the string-contacting finger members is securely fastenable upon the respective finger such that it is on the palm-side of the finger and on the second segment of the finger so that the user can manipulate the string-contacting finger members with one's finger tips. Each string-contacting finger member has a body with a single string contact stem extending from the bottom thereof and being capable of holding only one string against the fingerboard of the guitar. In addition, there are four multiple string contact attachments which can be detachably attached to the string-contacting finger members and which have bottoms that are capable of holding two or three consecutive strings or two nonconsecutive strings against the fingerboard of the guitar to achieve selected musical chords.
