FOUNTAIN PEN Application mea Aug-|1554, 1930. serial- No. 472,865.

The object of my invention is to provide in that type of fountain pens, having means for drawing ink into the pen barrel through its nozzle portion while the nozzle portlon and the pen point are dipped into a suitable ink supply, improved means for cleaning the nozzle of excessive ink adhering to the outer surface of said nozzle, after the nozzle and pen point have been removed from said ink supply.

More specifically it is the object of my 1nvention to provide in a fountain pen of the type above described, a casing in which the ink barrel and nozzle portion are slidably mounted, and to provide in connection therewith rotatively mounted means at one end of the casing for imparting movement to the ink barrel and nozzle, whereby the nozzle portion will be projected outwardly beyor one end of the casing, and to withdraw t said barrel and nozzle portion upon the first movement of the rotatively mounted means, and to provide a wiper for cleaning the nozzle portion as it is withdrawn.

"5 A further object is to provide in a fountain pen having an outer casing and a slidably mounted barrel portion including a collapsible ink retaining tube and a pivoted lever for collapsing said tube means whereby the lever will be locked against action only at the time when the nozzle portion is projected outwardly beyond the casing.

A further object is to provide in a fountain pen employing` a collapsible ink retaining tube, means or collapsing the tube before filling.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view of my improved fountain pen, the nozzle and barrel portion being shown in elevation.

Figure 2 is a similar sectional view showing the barrel and nozzle projecting outwardly to a filling position and showing the manner in which the mechanism for collapsing the ink retaining' tube is operated.

Figure 3 is a detail sectional view taken on the line 3-3 of Figure 1.

Figure 4 is a detail sectional view taken 55 on the line 4 4 of Figure 1.

Figure 5 is an enlarged detail sectional view of a portion of the mechanism for sliding the pen barrel.

Figure 6 is a detail sectional view taken 011 60 the line 6-6 of Figure 1.

My improved fountain pen comprises a cylindrical casing 10 having at one end a screw threaded portion 11, and at its opposite end an annular groove 12. The screw threaded portion of the casing is designed to support a sleeve 13, which is somewhat contracted toward its outer end. Said sleeve 13 is designed to slidably sup ort the nozzle portion 14 of the barrel 15. aid nozzle portion 70 14 is provided with the usual pen point 16.

The inner surface of the outer end of the sleeve 13 is provided with an annular groove 17 in which is mounted a. flexible packing member 18, which serves as a wiper to remove any excessive ink from the nozzle as the said nozzle is drawn inwardly into the easing 10. The barrel 15 has in its upper surface a notch 19 through which mechanism for collapsing the ink tube 20 may be operated, said ink so tube 20 being of the usual construction.

Supported on the inner end of the barrel 15 is a series of flexible strips 21 projectin forwardly and above the tube 20 and designe to be engaged by one end of a pivoted lever 22 mounted in a suitable slot 23 in the casing 10, at the time the barrel 15 and the nozzle 14.- a're moved to their outer limit of movement, as illustrated in Figure 2,whe`reby engagement of the strips 21 will cause the `tube 20 90 to be collapsed and a large portion of the air therein expelled through the passages leading to the pen point 16, and whereby ink will be drawn into said tube upon the return of the lever 22, the tube 20 and strips 21 to their normal positions.

Referring to Figure 1 it will be seen that when the barrel 15 is at its inner limit of movement, then one end of the lever 22 rests immediately above said barrel in such a manner that said lever cannot be operated to depress the strips 20, thus providing means whereby accidental operation of said lever may be avoided.

To prevent rotary movement of the barrel in the casing 10 I have provided a lug 24 in one side of said barrel designed to project into a longitudinal groove 25 on the inner surface of the casing 10. Said lug also limits the inner and outer movement of said barrel.

For imparting longitudinal movement to the barrel 15 I have provided a rotativelv mounted head 26 for one end of the casing 10, having a flange 27 designed to operate the groove 12. The member 26 is also provlded with a metal sleeve 28 rotativelv mounted 1n the adjacent end of the casing 1() and outside of the inner end of the barrel 15. The inner surface of the sleeve 28 is screw threaded, said screw threaded portion being designed to engage and receive laterally projecting pins 29 from the outer surface of the inner end of the barrel in such manner that rotation of the sleeve 28 will cause said barrel to be moved longitudinally, said rotation being imparted by the head 26.

Adjacent to the outer end of the sleeve'28 is an inwardly projecting flange 30 1n which is formed an annular groove 31 for receiving the inner ends of pins 32 projecting radlally and inwardly from the inner surface of the rear end of the casing 10. Said pins prevent longitudinal movement of the sleeve 28 relative to the said casing.

Thus it will be seen that I have provlded a fountain pen of simple. durable and in expensive construction having an outer caslng provided at one end with a contracted sleeve portion which serves as a grip member for supporting the casing and also as means for preventing the operators fingers from engaging the nozzle portion 14 when the pen is in use, and in connection therewith means for sliding the nozzle portion 14 outwardly at the time the filling operation takes place, so that any ink adhering to thel nozzle portion at the time of illing may be wiped from said nozzle portionby the member 18 as it is withdrawn to its normal position. The ink wiped therefrom is delivered to the pen point 16.

Thereby means is provided whereby the necessity of providing an eXtra wiping means for the nozzle end of the pen at the time of filling will be eliminated, as well as the dansaid casing and said nozzle portion, a pen l point for said nozzle portion, and means for sliding said barrel and said nozzle portion.

2. A fountain pen comprising a casing, a pen barrel having a nozzle portion, said barrel and nozzle portion being slidably mounted in said casing, whereby the nozzle portion may be projected outwardly and beyond one end of said casing, a wiper between said casing and said nozzle portion, a pen point for said nozzle portion, and means rotatively mounted adjacent to one end of said casing for imparting sliding movement to said barrel and nozzle.

3. A fountain pen comprising a hollow cylindrical casing having a contracted portion at one end, an ink retaining barrel within said casing terminating in a nozzle portion at one end, said nozzle portion being slldably mounted in the contracted portion of said casing, a packing between the outer end of said contracted portion and said nozzle portion, collapsible means within said barrel for drawing ink therein, and means carried by said casing for operating said collapsible means when the barrel and nozzle are at their outer limit of movement and for locking said operating means against movement when the arrel is at its inner limit of movement.

4. A fountain pen comprising a hollow cylindrical casing, an ink supporting barrel having a pen nozzle in one end slidably mounted within said barrel to cause said nozzle to be projected outwardly and beyond said casing, a pen for the outer end of said nozzle, and a yieldable wiper member between the nozzle and the outer end of said casing.

5. A fountain pen comprising a hollow cylindrical casing, an ink supporting barrel slidably mounted within said casing having one end designed to be pro'ectedbeyond one end of said casing, a yiel able packing between said casing and the projectin end of said barrel, a pen for the outer en of said barrel, and means actuated through said casing for drawin ink into said barrel when the said barrel 1s at its outer limit of movement.

6. A fountain pen comprising a hollow cylindrical casing, an ink barrel shdably mounted therein having one end adapted to be moved outwardly and beyond the correspond- -ing end of said casing, a yieldable wiper between said casing and the adjacent end of said barrel, a sleeve rotatively mounted in the opposite end of said casing having its inner surface screw threaded, lugs carried by said barrel projecting into said threaded portion, whereby rotation of said sleeve will cause the barrel to be moved longitudinally, means for preventing longitudinal movement of said sleeve relative to said casing, and a head adjacent -to one end of said casing Jfor rotating said sleeve.
