US Patent:
8324490, Dec 4, 2012
Filed:
Aug 23, 2011
Appl. No.:
13/215358
Inventors:
Bruce Walworth - Chelsea MI, US
International Classification:
G10D 3/00
US Classification:
84318
Abstract:
A capo for a dulcimer or other stringed instrument comprises an L-shaped member coupled to a bar member for applying pressure to the strings. A lever pivotally coupled to the L-shaped member includes a cam surface that engages with the bar member to facilitate a first position, wherein the cam surface is disengaged from the bar member for positioning on the instrument, and a second position, wherein the cam surface is engaged with the bar member, thereby applying pressure to the opposing sidewalls of the fret board to maintain pressure applied by the bar member against the strings. An extension member may be coupled to one end of the bar member with an adjustable fastener allowing the capo to accommodate fret boards of varying width.

US Patent:
20050236202, Oct 27, 2005
Filed:
Apr 23, 2004
Appl. No.:
10/831437
Inventors:
Bruce Walworth - Chelsea MI, US
International Classification:
B62K015/00
US Classification:
180208000
Abstract:
A collapsible personal transportation vehicle may be compacted and stowed in a mobile home, recreational vehicle, or the like, during periods of non-use and transport. Although the vehicle may be powered with a gasoline or electric power plant, a propane fueled engine is used due to its lighter weight and lack of fumes or leakage problems during transport. The vehicle may accommodate two riders, and achieve speeds of up to 30 miles per hour, or greater. To achieve sufficient collapsibility, the vehicle includes a seat assembly constructed from various pivoting members, whereby, during use, riders are seated above the motor, but during periods of non-use, the seat assembly folds down to fit into a space in front of the engine, with a height no greater than the engine and fuel tank(s). The preferred embodiment accommodates a roof structure as part of the collapsible seat assembly, which may be provided with a canopy and/or rear-view mirror, if so desired.
