PROVISIONAL SPECIFICATION.
Improvement in Construction of Fountain Penholders.
I, SAMUEL HARRISON of 69, Corporation Street, Manchester, in the County of
Lancaster, Printer and Stationer do hereby declare the nature of this invention to
be as follows :-
For improvement in fountain penholders by preventing acid in writing or copying
nk from corroding interior of hollow metal tubes used for fountain penholders or
rendering pulpy india rubber used for the same purpose.
To obtain these results I apply a coating of gutta percha to the inner surface
of the tubes so used.
This gutta percha lining is more especially intended to be adopted in the manu-
facture of the fountain penholder patented by myself in conjunction with one John
Mara on the twenty-eighth day of March, 1887 (No. 4575).
The gutta percha, being applied whilst warm, attaches itself at the holes in the
sides of the tube to the india rubber outer band forming the flexible sides, thus
protecting from corrosion the metal tube used as the reservoir of the fountain
penholder and preventing the india rubber flexible sides from becoming pulpy.
The coating of the whole inner surface also prevents leakage at the before-
mentioned holes in sides of fountain penholder.
Points of Novelty :-Prevention, by means of gutta percha lining, of corrosion
by writing ink of metal and pulping of india rubber fountain penholders.

COMPLETE SPECIFICATION.
Improvement in Construction of Fountain Penholders.
I, SAMUEL HARRISON of 69, Corporation Street Manchester in the County of
Lancaster Stationer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
'
For improvement in fountain penholders by preventing acid in writing or copying
ink from corroding interior of metal hollow tubes used for fountain penholders, or
rendering pulpy india-rubber used for the same purpose.
To obtain these results I apply a coating of gutta-percha to the inner surface of
the tubes so used.
This gutta-percha lining is more especially intended to be adopted in the manu-
facture of the fountain penholder patented by myself in conjunction with one John
Mara, on the 28th day of March, 1887, No. 4575.
The gutta-percha being applied whilst warm attaches itself at the holes in the
sides of the tube to the india-rubber outer band forming the flexible sides, thus
protecting from corrosion the metal tube used as the reservoir of the fountain
penholder and preventing the india rubber flexible sides from becoming pulpy.
The coating of the whole inner surface also prevents leakage at the before-
mentioned holes in sides of fountain penholders.
Method of Applying-A piece of gutta-percha is placed in the tube, heat is then
applied till the gutta-percha becomes liquid, when a piece of wire is inserted into
the tube and forces the gutta-percha up the inside of the tube filling the space
between the wire and the inner surface of the tube with gutta percha. The wire
is then withdrawn. The india rubber band forming the flexible sides of the pen-
holder is fixed in position before the gutta-percha coating is applied.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed; I declare that what I
claim is
1. The prevention, by means of a gutta percha lining, of corrosion by writing or
copying ink of metal and pulping of india-rubber fountain penholders.
Dated this 10th day of February 1892.
