Description:
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.

“For an improvement in the construction of the Ever Pointed Pencil Case; William Johnson, Philadelphia, Pennsylvania, July 27.

The whole specification is as follows: Specification of the slide for which the patent is craved. The slide is inserted in the pencil case; it is a circular wire, which, pressing against the sides of the case, acts as a spring to keep it in its proper place; this slide is pushed forward by a small pin connected with it, and projecting through the side of the case; the wire entering the point of the pencil case, when pushed forward, propels the lead, and operates with the same effect as the screw now in use.

We have here just the old fashioned pencil case, the slide being used to push forward the lead alone, instead of the lead enclosed in wood. For ourselves, we so well like the gentle and regulated manner in which the screw causes the point to advance, as to be of opinion that it would be no improvement upon the beautiful case presented to us by Messrs. Woodward & Co. of New York, to substitute for it the old method of a slide, pushed forward by the hand.”
