Gustavus Linderoos

要点:
  • gutavus linderoos因为拥有一项早期加法器的专利而引人注目,该专利现存于华盛顿特区美国历史博物馆。
  • 他设计这个加法器,专门用于实用的紧凑、廉价和耐用的仪器。
  • 古斯塔夫·林德罗斯(gustavus linderoos)是芬兰人,他是一位多产的天文学家和数学家,在1849年由于淘金热而来到加利福尼亚担任水手多年。

古斯塔夫·林德罗斯

1871年8月11日,来自加利福尼亚门多西诺的林德罗斯船长(1818-1885)申请了一项加法器的专利。该专利(美国专利号140146)于1873年6月24日获得授权。

林德罗斯的加法器与1650年代的相似,该装置被归功于。该装置的专利模型(参见下图)幸存至今,现在保存在华盛顿特区美国历史博物馆的收藏中。

该装置的目的是成为一个紧凑、廉价和耐用的实用仪器。在专利申请中,发明人声明:

这项发明的目的不仅仅是为了便于加法运算,尽管使用这个仪器可以轻松获得任何数字的和,而且不需要纸张或铅笔,并且完全准确,其主要目的是为那些需要不断累加一系列小数字的称重者、测量者和计数者,以及必须确保在任何点处获得的总数不会遗漏、出错或丢失,简化、廉价、口袋式仪器,不易出故障,并提供一种简单而确切的方法来保持在任何时间累积的数量,无论是重量还是尺寸。

让我们使用专利图纸来检查该装置(参见下图)。

这款盾形黄铜仪器的整体尺寸为:1.5厘米x 12厘米x 15.8厘米。

该装置上方是三个较小的轮子(带有齿轮的圆盘)。右侧的轮子从0到9逆时针编号,标有:100—1000。中间的轮子顺时针从0到9编号,标有:1000—10000。最左边的轮子以十位数顺时针编号,标有:10000—100000。每个轮子都有一个装饰性指针。

通过旋转大中央盘100次,使100—1000盘旋转一次(有一个用于十位进位的齿)。100—1000和1000—10000的小轮子也有十位进位的齿。这三个较小的轮子也可以单独旋转,以便更容易归零。
