American Watch Case Company LatheSurviving from their inception in 1893 until 1939, the American Watch Case Company was based in Manhattan, New York,and specialised in the manufacture of fine-quality gold pocket watch cases. Lathes must have been a sideline for the Company - or perhaps were a bought-in item - for only one is known to survive. Of around 3-inch centre height and 6inches between centres the lathe was of unusual construction with a flat-topped instead of bevelled-edged bed and a compound slide rest with the cross slide (and not the top slide) appearing to be mounted on a swivel. The lever for the headstock collet closer was also in an unusual position - pivoting beneath the headstock pulley and connected to a bar that passed through the left-hand wall of the headstock casting.
More details of this very interesting machine in due course. If you have an American watch Case Company lathe the writer would be very interested to hear from you.
Rick Smedberg wites:
Another Company with a similar name "Star Watch Case" had a factory in Ludington MI. I have seen photographs of its inside with a row of women sitting in front of these lathes with small round belts off the end going down through the floor. My mother and sister both worked there - but it was, apparently, shut down by the Swiss and then torn down to build the New Ludington Marina Project. I think the lathes were made for them for a special purpose, there is a similar one in the local antique store with some other watch tools from the watch case factory. I'm sure that most of the old machinery was scraped and the floors burned to recover the gold. In the early 20th century Ludington had lots of machine shops building machinery - so they may indeed have been manufactured locally.
美国表壳公司车床
美国手表盒公司从1893年成立至1939年，始建于纽约曼哈顿，专门生产优质金色怀表盒。车床一定是公司的副业 - 也许是被买进的产品 - 因为只有一家公司能够生存。大约3英寸的中心高度和6英寸的中心之间的车床是不寻常的建设与平顶而不是斜边床和复合滑动休息与十字滑动（而不是顶部幻灯片）似乎是安装一个旋转。主轴夹头闭门器的杠杆也处于一个不寻常的位置 - 在主轴皮带轮下方枢转，并连接到穿过主轴箱铸件左侧壁的杆。
在适当的时候这个非常有趣的机器的更多细节。如果你有一个美国手表公司的车床，作家会很感兴趣的收到你的来信。

另一家名为“Star Watch Case”的公司在密歇根州的Ludington有一家工厂。我看到里面的照片，一排女人坐在这些车床前，小圆的皮带从地板上掉下来。我的母亲和姐姐都在那里工作，但显然是被瑞士人关闭，然后被拆除去建造新的拉丁顿码头项目。我认为这些车床是为了特殊目的而制造的，在当地的古董店里有一个与钟表工厂的其他钟表工具类似的工具。我敢肯定，大部分旧机器都被刮掉了，地板被烧毁以恢复黄金。在20世纪初，路丁顿有许多机械制造商制造机器，所以他们确实是在当地制造的。
2、Derbyshire & WW Lathes USA
德比郡公司是美国长期生产的制造商，自1911年以来一直提供微型高精度车床和卧式铣床给参与生产关键标准的公司和政府。该公司的基础是：
910 Boston Turnpike，Shrewsbury，MA 01545，USA电话：（508）842-8319
创始人弗雷德里克·威廉·德比（Frederick William Derbyshire）于15岁（1874年）在马萨诸塞州沃尔瑟姆（Waltham）的刚成立的美国钟表工具公司（通常缩写为AWTC）学徒。在十九世纪后半叶，二十世纪早期，沃尔瑟姆镇是美国精密工程的中心，与斯塔克，沃尔瑟姆机械厂，霍普金斯钟表工具公司，BCAmes，WH尼科尔斯，韦德工具公司和许多其他知名的*高级公司都相距几英里。德比郡公司加入的公司，仅仅在二十四个月前由两名男子组成，他们的名字就是制表工车床中最好的 - 韦伯斯特（Webster）和惠特科姆（Whitcomb）的代名词。韦伯斯特已经上升为“美国钟表公司”的总监（工程经理），而惠特科姆则是精密机械和工具制造公司“Ballou，Whitcombe＆Co.”的负责人。
十八年来，在其他熟练的设计师和工程师的协助下，他们开发了一系列日益成熟和制作精良的微型车床，最终于1888年9月推出了设计制表工艺车床的世界标准，韦伯斯特 - 惠特科姆 - 或“WW”，因为它变得更为人知。这个车床是一个开创性的发展，除了更轻的“日内瓦”型，完全取代了早期的所有类型，包括着名的瑞士环球（或英国心轴，因为它也已知）和底部。
