- Be it known that E.;L. PRATLlate of Beverly, Es-

"sex county, Massachusetts, invent-ed a new: andv useful Pen-Fountain and I do herebydeclare that the follow ing, taken in con'nection with `the drawings which acf company and form part of this specication, is a'description of `his invention, suiicient to enable those skilled intbeartto practise it The invention relates to that class of fountain-.pens in which a foram'inous metal tongue lies in the hollow of thepen, hack of the nib, the perforations enabling the tongue to hold, between it and the peu, a. large quantity of ink. i f

. The present: invention consists in a fountain, made with two perforatedand grooved, or tinted tongues,

one lying 4in the concavityiof the pen, and one upon the outer surface thereof, the two being so united at `their rear` ends, that the pen can be slipped between them, their pressure againstthe pen holding them in position.

` The drawingsrepresent*apen-fountain embodyingl the improvement.

A shows a front-end view'of it. B, a rear-end View.V T C, a side elevation Lof the D, a`bottom view. E, a top view. v i i i a denotes the lower tongue, made witha series of perforatious, and with a longitudinal channel, or de-y pression, b, the tongue extending from a transverselycurved piece, c, lasseen at D. f The top of the tongueisrso formed as to project up into'the concavityof the under side of the pen, andi from the tip to thenplate c the tongue isbeut down, so as to leave a sort of chamber, or ink-holding space be-A fountain and pen.

. tween the tongue-and the surface of the pen, while,

the better to retain `the ink, yand guide it to the pennib, the tongue may 'be formed slightly concave, and is provided with the central-channel b. 1

The plate c is united, on one Yside7 to another plate, e, (or forms part thereof,) the two plates being bent concentrically, as seen at B,l and from the outer plate t e, another perforated, or foraminous tongue, f, extends,

this tongue being curved .(in the direction of its length) conversely to the tongue b, and also having atransverse curve and a central'lchannel, or groove, similarly v.to the tongue b.

This ltongue extends down upon the outer surface of the peu, from the shank toward the nib, as seen at C. A f f The fountain is slipped upon the nib of the pen, and pushed up upon the pen-shank,-until the tips of the two tongues lie back from the nib, as seen in the drawings, the tip of each tongue lying near to or against the surface of the pen, and each'tongue, from the tip, re-

treating from 'the pen, as seen, so that upon each side of the pen is an inkretainingohamber, or reservoir, from which the ink is supplied to the nib ofthe peu. Instead 'of thrusting the nib through the plates, the

A edge ofthe shank ofthe pen may be thrust iu between the open, or unconnected ends readily understood.

Y The perforations in the two tongues ofthe fountain ai'd in holding .the ink, ina considerable body, between the surfaces of the pen and the inner surfaces of the ton gues,`

and the groove, or central ute in each tongue conducts and directs the ink to the slit in the pen-nib, or point.

The fountain, as made', described, and claimed, clasps upon the body of the pen; and not upon the pen-holder.

. N claim is made to a mere plain bifurcated` fountain, nor is claim made to a perforated fountain, unless' Y Vit is grooved and presents a perforated tongue on each surface of the`pen,and is ,made to clasp upon the pen- Whatis claimed, is-

A pen-fountain, having two foraminous fiuted tongues, af, arranged to clasp upon the body of a pen, and betweene'ach of which, and the adjacent surface of the pen, au inkholding and nib-supplyingreservoir is formed, Aas described.
