介绍（中）	来自密苏里州圣路易斯的班卓琴制造商Hercules McCord于1884年生产了这款班卓琴。颈部设计是传统的。然而，轮辋总成巧妙地解决了与轮辋设计和头部紧固总成相关的几个技术挑战，该总成包含了McCord四项专利创新中的三项 19世纪80年代，班卓琴的设计和技术出现了重大创新。在那十年里，有75项与班卓琴有关的专利在美国专利局注册。这些专利中的许多都集中在用于拉紧皮肤头部的机构或班卓琴轮圈本身的设计上。一个挑战是尽量减少拧紧头部所需的工作量。第二个解决了拧紧机构的设计和位置，以最大限度地减少对玩家造成不适的可能性。这通常是通过将机构封装在专门设计的轮辋中或将机构设计为轮辋的一个组成部分来实现的
介绍（英）	Hercules McCord, a banjo maker from St. Louis, MO, produced this banjo in 1884. The neck design is conventional. However, the rim assembly, which incorporates three of McCord’s four patent innovations, ingeniously addresses several technical challenges related to rim design and head tightening assemblies. The 1880s saw major innovations in banjo design and technology. 75 patents related to banjos were registered with the U. S. Patent Office during that decade. Many of these patents focused on either the mechanisms used to tighten the skin head or the design of the banjo rim itself. One challenge was to minimize the work it took to tighten the head. The second addressed the design and location of the tightening mechanisms to minimize the likelihood of causing discomfort to the player. This often was accomplished by either enclosing the mechanisms in a specially designed rim or designing the mechanisms as an integral part of the rim. McCord’s all-metal rim design deals with these technical challenges. The back of the bowl-shaped rim consists of 24 spokes radiating from the center. Cables are enclosed in each of the spokes and are attached to the metal band that tightens the skin head over the rim. The tension of each of the 24 cables is regulated simultaneously by a single screw mechanism at the center of the back of the rim. McCord’s design dispenses entirely with multiple head tightening mechanisms that have to be tightened individually and are often protruding from the exterior of the rim, which can be uncomfortable for the player. In spite of the elegant ingenuity of the design, this banjo is the only known example incorporating McCord’s spoked cable head-tightening system. (Peter Szego, 2020)
