Description: |
| William H. Cooley - patent attorney
My invention has for its object the construction of a scale, which may be used for measuring the diameters of lenses or other similar articles and which by the removal of the attachment especially adapted for holding the lenses while they are being gaged or measured can be used as a machinist's calipering gage or scale and which also by the removal of the calipering-slide maybe used as a machinist's scale or measure, with an end piece against which one of the surfaces of the object to be measured may be held, so as to come exactly even with the end of the scale. This end piece is readily detachable, and after its removal the scale may then be used as an ordinary machinist's measuring-scale. |
