FOUNTAIILPEN.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed February 9, 1920. Serial No. 357,115. a

T 0 all whom it may concern Be it known that I, EDWARD J. Gasrnn, a citizen of the United States, and residing at New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Fountain- Pens, of which the following is a specifica tion, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to fountain pens and particularly to devices of this class known in the art as self-filling fountain pens, and the object of the invention is to provide improved means for operating devices of this class which will produce the desired result in a more efiicient and economical manner by reason of the simplicity of the device and the method of constructing and assembling the same in connection with the body portion of the fountain pen.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the Fig; 5 a view looking in the direction of the arrow 5 of Fig. 2; and,

Fig. 6 a view similar to Fig. 1-but showing only a part of the construction and indicating the method of mounting my improvement in connection with the body portion of the fountain pen.

In the drawing I have shown at 10 the main tubular body portion of a fountain pen of the 'class under consideration. One

endof the body portion is closed as shown at 11 and the other end thereof is externally threaded as shown at 12 to receive a detachable cap 13. Detachably mounted" within the body portionlO is the usual supplemental. body portion 14: which is connected with and held in engagement with the main bodyportion l-Q in any desired manner.

one end of the supplemental body portion f 14c is a pen point 15 and connected With the other end thereof is the usual flexible tube 16 composed of elastic rubberor other suit able material, and which constitutes the ink reservoir or container of thepen.

The above described construction merely shown and described to illustrate a use of my invention and forms no part of this invention and, in practice, I connect with the main body portion 10 a manually operated device 17 which operates in 0011- nection with the flexible tube 16 to dis-' charge the ink from said tube or for refilling such tube. The device 17 consists of a metallic strip 18 mounted longitudinally of and within the tubular body 10 and to the inner end of which strip'18 is pivoted a link 19, which link 19 is also pivoted to another strip 20 as shown at2l. 1'll1eouter end portion of the strip 18 extends through an aperture 22 in the closed end 11 of the body 10, and is bent into an approximately hoole shaped member 23. hook-shaped member 23 extends in parallel lines with the strip 18' and the part 25 thereof extends transversely of-the strip 18 and the part 24; and'is slightly curved to correspond with the curvature on i the outer face of the end 11 of. the body 10 as clearly shown in Figs. 1, 2 and 6 of the drawing.

The part 24 of the hook-shaped endpor tion 23 passes through another aperture26 in the end 11 of the body 10, asis clearly shown in Figs. 1 and 2, while the transverse part 25 entersa recess 27 in the face of the end 11. thus producing a neat and finished appearance when thedevice is in its normal position, as shOWIl in Fig. 1. The recess 27 is enlarged at the opposite sides thereof, as shown at 28 in Fig. 5 of the drawing, to permit of the insertion-of the nails of the fingers ofjan operator in withdrawing the device 17 into the position shown in Fig. 2. I

One end portionof the strip 20 isislightly curved as shown at 29 and ope'rates'in connection with a concaved inner face so n the head 11 of the bodylO to permit of tlie free action of said strip over said face'in the use of the device. a In attaching-the device 17, or theseparate parts thereof, to thebody ll),

the strip 18 is first fashioned intothe form The part 24: of the shown in full lines in Fig. (iand the'outer'or free endportion of thestrip 18 is passed through the aperture 22 with the strip 20 in the position shown in said figure after which the extended end portion of the strip 18 is bent into the hook-shaped member 23 as is indicated in dotted lines in said Fig. 6, and

- the strips 18 and 20 are then moved into Fig. 1, and if it be desired to fill the flexible nominal cost, and while tube 16 with ink, the part 25 of the hook shaped member 23 is grasped by the operator and moved outwardly into the position shown in Fig. 2, in which operation the strip 20 is forced into the position shown in said Fig. 2 by the action of the link 19 on the strip 20, thus operated by the outward movement of the strip 18, and the flexible tube 16 will be fully compressed and all the air therein forced out through the supplemental body portion 14 in the usual manner, and by slowly returning the device 17 into its normal position as shown in Fig. 1, the er;- pansion of the contracted flexible tube 16 will draw inkthereinto, if the pen point 15 be placed in a fluid ink. V

course, it will be understood that the fountain pen may be filled and'refilled as many times as'desired, and the ink removed from the flexible tube 16 for the purpose cleaning the fountain pen, or for repairing the same, and it will also be seen that with my improved means for accomplishing the desired result little or no labor will be required; in attaching the same to the body portion of the fountain pen, and by reason of the simplicity of the construction of the device, the desired result is produced in a very effective and efiicient manner and at a I have shown certain details of construction for'carrying my invention into effect, I am not necessarily limitedto these details. and various changes in and modifications of the construction herein what I claim as new and desire to secure by Letters Patent, is 2- 1.
