FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 407,585, dated July 23, 1889.

Application filed January 2l, 1889. Serial No. 296,976. (No model.)

To 'all whom it may concern/.-

Be it known that I, JOSEPH FRIEDMANN, of Seymour, in the county of New Haven and State of Connecticut, have invented a new Improvement in Fountain-Pens; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a side view of the pen complete; Fig. 2, a longitudinal section through the penholding portion enlarged; Fig. 3, a transverse section on line w x of Fig. 2; Fig. 4, the penholding portion C D detached, but the parts set together preparatory to attachment to the holder; Fig. 5, a perspective view of the part D, looking upon the passage side.

This invention relates to an improvement in that class of fountain-pens which are adapted to use a split-pointed pen, and in which the handle of the pen is tubular to form the fount, and the pen, carried by a socket, removably attached to the lower end of the fount, with a passage through the socket from the fount to the inside of the pen, and in which a Atongue projects from the socket onto the back of the pen, forming what is called the back-feed, the object of the invention being a simple construction of the pen-holdin g portion of the socket, which will admit of the easy removal or introduction of the pen when occasion requires, yet hold the pen in the rmest possible manner; and the invention consists in the construction as hereinafter described, and particularly recited in the claims.

Arepresents the handle, which is best made from what is commonly called hard rubber, and is of tubular shape, its upper end closed, and its lower end screw-threaded to receive the socket B, which is correspondingly screwthreaded, and, as seen in Fig. 2, the socket is also tubular, opening directly into the fount.

The pen-holding portion of the socket is made separate from the socket proper, and is formed in two parts C D, as seen in Fig. 4, the division being longitudinal. The interior of the socket B is screw-threaded, and the upper ends of the two parts C D together are correspondingly screw-threaded, so that when the two parts are set together, as seen in Fig. 4, the two parts may be screwed into the socket, and, as seen in Fig. 2, be as firmly held as if made in a single piece. The socket B is preferably of a length to extend down onto the parts C D, and so as to embrace them below the screw, to give additional strength or support to the two parts. The division between the two parts is formed by a cut a l from the lower end upward, made by a transverse curved or eccentric cut, the curve corresponding to the transverse curve of the pen, as seen in Fig. 3. This cut forms a recess to receive the pen; but at the upper end or screw-threaded portion of these two parts the cut is made so that the two parts set soland, as seen in Figs. 2, 3, and 5, an inside or front feed-spindle H is arranged in the passage, serving to conduct the ink down upon the inside of the pen but the particular construction of feed forms no part of the-present invention, it only being essential that there shall be a feed-spindle in the passage leading onto the inside of the pen.

The feed-spindle and the back-feed E are both elastic and yield under the action of the pen, returning to their normal position with the pen, the movement of the spindle serving to facilitate the flow of ink from the fount to the point of the pen.

I claiml. In'a fountain-pen, the pen-holding portion of the socket, constructed in two parts C D, divided longitudinally, the division being in a transverse curve corresponding to the transverse curve of the pen, and so as to form a recess between the two parts to receive the pen, the upper ends of the two parts coming together and externally screw-threaded, so

as to be set together and screwed into a eorrespondingly-threaded socket, the part (l construeted with a tongue E, projecting therefrom onto the back of the pen, and the part D constructed with a longitudinal passage G, leading from the fount to the inside of the pen, and an elastic feedspindle H through said passage onto the inside of the pen, substantially as described.

2. The combination of the tubular forint A, closed at its upper end, the tubular socket B, detaehably connected tothe lower or pen end of the fount, the pen-holding portion of the socket made in two parts C D, the division between the two parts being longitudinal and transversely curved corresponding to the curve of the pen, and so as to forni a recess between the two parts to receive the pen, the upper ends of the two parts together screw-threaded corresponding to an internal screw-thread formed upon the interior of the socket B, the part C constructed with a tongue projecting from its lower end onto the back of the pen, and the part D constructed
