Description: |
| This invention has reference to improvements in gages, which are particularly adapted to those of the caliper order. The object of this invention is to increase the measuring capacity of gages for making delicate measurements without increasing the traverse of the measuring mechanism. Another object of the invention is to produce a gage in which an adjustable measuring-post is carried by a traversing-indicator. Still another object of the invention is to increase the measuring capacity of a caliper gage without obstructing the anvil end of the frame. The invention consists in the combination with the traverse-screw of an adjustable measuring-post. The invention further consists in the peculiar construction of the traverse-screw having means for securing a measuring-post thereto, together with such other peculiar features of construction and combination of parts as will hereinafter be more fully described and pointed out in the claims |
