H tion of my improved fountain pen casing The sh'ell 1 8 Ihas' aP cylindrical frontend and cap, l portion 22 and' a"c`ylindri'c'a`1 intermediate tically casing 10.1
portion 23, both of these portions having al smooth bore and between the portions 22 and 23 the shell 18 is provided with a depressed annular portion 24, see Fig. 7, whichl is screw-threadedV at 25 as illustrated in Fig. 2. The rear end of the outer shell 19 is closed byproviding a. ange 26 thereon which engages and holds in position a disc V27'. The outer shell is preferably formed of rand providing an air tight ychamber 29 in the cap 11 to receive a pen 30. f
The particular class of fountain pen shown in Fig. 1 is of that character in which an ink sack 17 is provided which is oper ated to feed the ink thereinto by any suitable means such as a lever 31. It will be seen that the outer diameter of the cap 11 is practhe same as the outer diameter of the In Fig. 3 .a modified form of cap is illustrated inl which there is embodied an outer shell 32, an inner shell 33 and an intermediate shell 34. yIn this form of-my invention the intermediate shell 34 is substantially the sam-e as the inner shell 23, but the annular flange 20 is omitted therefrom and is replaced by means of an annular kflange 35 on the front end of the shell 33,
otherwise the cap is the same, as the cap illustrated in Fig. 2 .and the functions performed are the same, except that the flange 35 performs the function of the flange 20 in Fig. 2.
In Fig. 4 a modified form of the cap is illustrated in which there is an outer shell 36, an inner shell 37 and an intermediate shell 38. The inner shell 37 has an annular `flange 39 upon its front end formed in a differentwmanner than in the inner shell 33 illustrated in F ig.` 3,V that is, in F ig. 4 the flange 39 is formed by turning the same outwardlyl while in Fig. 3 the flange 35 is formed by turning the flange inwardly. The
operation of and the function performed by the diH-erent parts of the cap 36 are, however,the same as in the form of my invention illustrated in Fig. 3.
In Fig. 6 a portion of the casing is illustrated in its finished form, that is, with the screw thread 14 formed on the front cylindrical end thereof.
In Fig. 7 the form of the inner shell illustrated in its finished shapein Fig. 2 is illustrated for the purpose of illustrating the depressed annular portion 24 located between the two cylindrical smooth bored porytions 22 and 23 and illustrating the appearance of the inner shell, Fig. 2 before the screw thread 25 is' formed thereon.
The manner of using the device hereinbefore described is the same as in other fountain pens, that is, the cap is screwed on to the front end ofthe casing when the pen isk not in use and unscrewed therefrom and placed upon the rear end of the casing when in use.
