Leadholder and Lead Pointer Patents

During the heyday of manual drafting, great energy was expended developing improved drawing equipment.  In this section you will find patent information including links to patent drawings for leadholders and lead pointers.  The patents are also cross-referenced to items in the Galleries that are embodiments of the patents.

Notes:

The dates listed next to patents at left refer to the earliest date of application in an attempt to date the inventions as closely as possible to the time of conception rather than the time some bureaucrat finally got around to examining the application.

The historical information symbol (Historical Information) next to patent index entries indicates information in addition to the historical patent documents is to be found on these entries.
