SignedGold-painted cast-metal medallion on peghead face, in raised letters: Bolander’s / Banjo Uke / TRADE / MARK / [lyre]Stamped onto back of peghead and twice inside back of resonator in black ink: BOLANDERS / UKULELE BANJO / SAN FRANCISCO / 7 PATENT ALLOWED, OTHER PENDING
DescriptionJohn Bolander filed for three patents relating to banjos. All instruments illustrated on the patents are banjo-ukuleles, as opposed to other styles of banjos. One was applied for on June 25, 1917 and was awared US patent 1378212A on May 17, 1921. It encompassed an improved means of attaching the head and a method for inserting the lower ends of the strings into the rim. Another was applied for on December 3, 1917 and was awarded US patent 1454620A on May 8, 1923 encompassing the resonator, a finger guard mounted off the lower bass side of the fingerboard, and a means of attaching the head. A third was applied for on January 28, 1918 and awarded US patent 1365450 on January 11, 1921. This patent covers the resonator, or sound reflector, device.
The claim on the ink stamp of this instrument that seven patents were allowed and others pending is not supported by recorded patents of the USPTO. It is likely that Bolander had multiple pending applications, but not all were awarded even at the time of the making of the stamp.
Bolander and Alvin Keech, also of San Francisco, are credited with the earliest patents and development of the banjo-ukulele. Bolander was later better known as a violin and bow maker.
