GOLD PEN.

Specification of Letters Patent No. 10,348, dated December 20, 1853; Antedated July 14, 1853.

To all whom it may concern:

Be it known that we, EDMUND H. BARD and HENRY H. WnisoN, copartners under the firm of Bard & Wilson, of Philadelphia, in the county of Philadelphia, State of Pennsylvania, have invented an Improvement in the Construction of Gold Pens; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and the letters of reference marked thereon.

The nature of our invention consists in the combination of the point commonly called the French point, (which is made by compressing the sides thereof into planes, inclined angularly) and the ordinary cy lindrical barrel whereby the pen in being used has all the advantages of the lateral action of the one, and can be inserted in the ordinary penholder as in the other.

To enable others to make and use our invention we proceed to describe its construction and operation.

After the pen is out out in the rough into the desired shape, it is placed in a die the sides of which, from the shoulder to the point, are planes inclined so as to form an obtuse angle with each other, while the other portion of the die retains the ordinary cylindrical form, which causes the pen to assume the form aforesaid, as is shown in the accompanying drawings.

tofore constructed in which a portion of the metal has been filed away from the sides of the nib so as to give elasticity to the pen by a diminished thickness of metal. Although the "external surface of the sides of the nib so filed presents somewhat the appearance of two planes, yet the inner surface of the nibs preserves its. cylindrical shape. The elasticity of such pens is due to the reduced thickness of the metal at the part filed and is not due to the divergence of the angular planes forming the sides of the nub during the action of writing. Such pens are inferior to the pens invented by us in elasticity and durability. Being of unequal thickness of metal they are apt to break at the part where the metal is filed down.

Our pens on the contrary are of uniform thickness, are made by the single action of, the dies without any subsequent filing and owe their elasticity solely to the action of the angular planes forming the sides of the nib.

Having thus described our improvement, we do not desire to claim the employment of flat nibs when composed of two pieces, as such pens have been heretofore made; but

\Vhat we claim, and desire to secure by ner hereinbefore described.
