FOUNTAIN ATTACHMENT FOR PENS.

SPECIFICATION forming part of Letters Patent No. 710,599, dated October '7, 1902.

Application filed March 24,1902.

To all whom it may concern:

Be it known that 1, JOHN PIERPONT MUR- DOCK, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Fountain Attachments for Pens; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will euable others skilled in the art to which it appertains to make and use the same.

This invention relates to fountain attachments for pens; and the object in view is to provide a device of this class which is adapted to be applied to any form of pen without interfering with the free action of the nibs of the latter or necessitating a material change in the structure of the pen and operating to supply the pen with a regular flow of ink without requiring a continual replenishment by the tedious and inconvenient ordinary practice of dipping a pen into an ink-receptacle.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a plan view of a pen, showing the improved fountain attachment applied thereto. Fig. 2 is a longitudinal vertical section of the pen and attachment. Fig. 3 is a transverse vertical section taken in the plane of the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the attachment.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a pen of anypreferred or ordinary form of construction having the usual attachingshank 2 of cylindrical form to fit within a holder. The shank 2 near the main body of the pen is formed with a pair of oppositely-disposed transverselyalined stop indentations 3, which are struck downwardly from the shank, and at a central point between the said projections is an upstruck seat 4, as clearly shown by Figs. 2 and 3. The attachment comprises a spoonshaped body 5, which tapers or is gradually reduced toward its front end and is gradually curved upwardly in a concave plane, as at 6,

of the said body 5 to provide for close fitting of the front reduced end of the attachment against the under side of the nibs of the pen. The upper portion of the body 5 is open, as clearly shown by Fig. 4, and extending from the center of the upper edge of the rear terminal of the said body 5 is a shank 7 of a resilient nature and having opposite straight edges 8, converging toward the rear end of said shank. The shank is longitudinally slotted and a portion of the metal removed, as at 9, to provide a forwardly-projecting spring-tongue 10, which is of less length than the shank and has its front end enlarged and indented or struck up to provide a securing projection 11.

In applying the improved attachment to a pen the shank 7 is pushed rearwardly between the stop projections 3 while in close .relation to the shank 2 and until the locking projection 11 snaps into the seat 4. It will be observed that the stop projections 3 act as guards to prevent lateral movement of the shank and displacement of the attachment, and the stop projection 11, carried by the tongue 10, serves to secure the attachment to a pen in such manner as to afford a strong resistance to accidental disengagement under ordinary uses, but permitting the easy disconnection by manual operation.

The attachment will be formed of non-corrosive metal, and the body 5 is of such dimensions as to hold quite a large quantity of ink without forming an inconvenient or unsightly projection. When the attachment is applied, the'upper open portion of the body 5 is held in close relation to the pen-body, and during the action of the nibs in writing a small portion ofthe ink is permitted to feed from the attachment to the nibs without flooding, and by this means one dip of the pen in a receptacle containing ink will charge the attachment with a quantity of the latter sufficient to write for a considerable length of time without requiring a replenishment of the supply of ink within the attachment.

The attachment will be formed by striking the same up in suitable dies, and it will be observed that small and intricate parts are entirely lacking therein. Furthermore, a great advantage in the present form of fountain attachment is that it may be quickly de- Lin tached from one pen and easily applied to another, and as there is no wear on the attachment its durability and service are materially increased. By having the opposite edges 8 of the shank converge toward the rear end of the latter the frictional point between the stop projections 3 will be more effective, and the retention of the attachment in connection with a pen is thus rendered more positive.

Having thus fully described the invention, what is claimed as new is 1. The combination of a pen having transversely-disposed stop projections and an intermediate seat, and a fountain attachment comprising a body having a rearwardly-projecting shank adapted to have its side edges engaged by the said projections and including a tongue with a locking projection to engage the said seat.

2. The combination ofa pen having a shank with retention devices therein, and a fountain attachment comprising a body having a rearwardly-projecting shank including a freelymovable tongue, the opposite side edges of the shank and the forward extremity of the tongue engaging the retention devices of the pen.

3. The combination of a pen having a shank with transversely-alined downstruck projections and an upstruck seat between said projections, and a fountain attachment comprising a body with a rearwardly projecting shank having opposite rearwardly-converging side edges to engage said project-ions, and a forwardly-projecting tongue with a front locking projection to engage the seat.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN PIERPONT MURDOCK.
