Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A bar for sliding use on strings in playing a stringed instrument in the manner of a Hawaiian guitar, comprising in combination: (a) a rigid tubular member which is generally finger-sized and adapted to be manually held against one or more strings of the instrument during the playing thereof; (b) a string-vibration-responsive electrical pickup fixedly secured to said rigid member and adapted to be connected to an electrical audio amplifier; (c) separate means closing one end of said tubular member; and (d) electrical conductor means passing through said closing means in circuit with said pickup.
Claim 2
Dependent Claim
95 words
A bar for sliding use on strings in playing a stringed instrument in the manner of a Hawaiian guitar, comprising in combination: (a) a rigid tubular member which is generally finger-sized and adapted to be manually held against one or more strings of the instrument during the playing thereof; (b) a string-vibration-responsive electrical pickup fixedly secured to said rigid member and adapted to be connected to an electrical audio amplifier; (c) separate means closing one end of said tubular member; and (d) electrical conductor means passing through said closing means in circuit with said pickup.
Claim 3
Dependent Claim
15 words
