The upper end of the magazine is closed section, taken on line 5-k-5 in Fig. 2` and also by an integral end Wall 29. The magazine is drawn on an enlarged-scale. further provided with a central or axial bore to receive the sleeve 19 over which the magazine is to be engaged. The interior of the magazine is subdivided into a plurality of ink material holding compartments or pockets by radial walls or partitions 30 which project inwardly from the external side walls thereof to converge upon and abut the sides of the sleeve 19; the compartments or pockets being open toward the latter. The walls of said sleeve 19 are provided with a plurality of longitudinal slots or openings 31 corresponding in number with the number of compartments or pockets with which the magazine is provided; said slots or openings being respectively aligned with the respective magazine compartments or pockets. At its lower open end, the magazine is provided with a countersunk seat 32 to receive a closure washer or disc 33 to close the lower ends of the compartments or pockets. Said mpartments or pockets are each charged or packed with a body 34 of suitable soluble ink material. This ink material may be provided in any well-known form, such e. g. as of stick form, or in the form of a powder or paste. After the compartments or pockets are charged with the ink material, the closure washer or disc 33 is engaged in the seat 32 to close the lower ends of the charged compartments or pockets. The ink charged magazine is slid over the lower end of the sleeve 19 and pushed upwardly thereon so that its upper reduced end portion 27 is entered in the lower open end of the barrel 10, until the margin of the skirt 35 of the latter is engaged by the shoulder 28, and the upper end of the magazine abutted against the underside of the head 20 of said sleeve 19. Said sleeve head 20 is provided with a depending positioning pin 36 which enters an opening in the upper end wall 29 of the magazine, thus positioning the latter so that its ink charged compartments or pockets are respectively aligned with the respective slots or openings 31 of the sleeve 19.

The reference character 37 indicates the throat member of the fountain pen, the lower end of which is suitably bored to receive insertion of a pen nib 38 and a feed bar 39; the latter having a channel or passage 40 open to the inner side of the pen nib to convey writing fluid to the latter. At its upper end the throat member is closed by an end wall 41 having a central opening 42 to receive the lower end of said sleeve 19. Imbedded in the throat member, intermediate said opening 42 and the feed bar 39, is an internally screw-threaded nut-member 43 which is immovably affixed to said throat member. The lower end portion of said sleeve 19 is externallyscrew-threaded, as at 44, for engagement by said nut-member 43. After the ink-charged magazine is assembled on the sleeve 19 and inserted into the g lower end of the barrel 10, the throat member 37 is screwed home onto the end of said sleeve, thereby securing in operative assembled relation the various parts of the pen, and at the same time coupling the upper end of the feed bar passage 40 in communicating alignment with the passage 45 of the feed tube 17 which communicates at its upper end with the interior of the sac 15. The Sac 15 is compressible bymeans of the usual filling lever means 46, or any other manipulatable lling device, accessible at, the exterior of the barrel 10, whereby, when the throat member 37 is dipped in water or other solvent, and vthe air driven out of the sac 15 by compression, the water or solvent will be forced by atmospheric pressure upwardly through the pennib, feed bar passage and feed tube into the sac 15 so as to store a supply thereof within the latter. It will be obvious that the compressible sac 15 is merely illustrative of one of several usual types of water or solvent reservoir means, and consequently, in its broader aspects, this invention is not to be limited to such form of reservoir or pen filling means.

The feed tube 17 is provided in its side with a single port 47, so that by turning movement of the feed tube 17 relative to the sleeve 19 and associated ink material magazine, the feed tube passage 45 may be selectively brought into communication with the ink charged compartments or pockets of the magazine. Since the feed tube 17 is affixed or united to the barrel 10 by means of the plug 13, which is mutually secured to and between these parts, it follows that by turning the barrel 10 relative to the mutually interengaged and secured sleeve 19, magazine 26 and throat member 37, the feed tube 17 will be turned within the sleeve 19 so as to bring the feed tube port 47 into registration with any given slot or opening 3l of the sleeve 19, and consequently into communication with the corresponding ink-charged compartment or pocket of the magazine. In order to assist the user in readily and quickly ascertaining the operative position of the feed tube relative to a given ink compartment or pocket of the magazine, the outer surface of the magazine is provided with a register mark corresponding to the position of the feed tube port 47, and the skirt 35 of the barrel with positioning marks or indicia corresponding to the positions of the ink compartments or pockets of the magazine.

In the operation of the pen, after the feed tube port 47 has been aligned with a given ink charged compartment or pocket of the magazine, water or other solvent from the reservoir sac 15 will flow downwardly through the passage 45 of the feed tube 17, and will pass through the port 47 and aligned sleeve opening or slot 31 into contact with the ink material 34 of the operative magazine compartment or pocket. In thus contacting with the ink material the water or other solvent will dissolve portions thereof which will thus create a writing fluid which will flow back through the port 47 and downwardly through the lower end of the feed tube passage 45 and thence into the channel 40 of the feed bar 39, whereby the writing fluid is delivered to the pen nib 38 to charge the same for desired writing operation.

It will be obvious that after the ink material is exhausted from one compartment or pocket of the magazine, the feed tube may be turned so as to register its port 47 with another compartment or pocket of the magazine, and so on until the entire supply of ink material has been exhau'sted and the magazine is empty.

The empty magazine may be removed from the pen and recharged with ink material, or replaced with a new filled magazine. This is accomplished by unscrewing and removing the throat member 37 from the end of the sleeve 19, after which the magazine may be in turn slid off of the sleeve, and thereupon recharged, and then again replaced in operative assembled relation to the pen, and secured in such relation by replacing the throat member 37. It will be apparent that all of these operations are easily and quickly accomplished, and that when the parts are assembled they are all securely interrelated together in operative condition, and in such manner as to assure against any leakage of either solvent or writing fiuid to the exterior surfaces of the pen above the pen nib.

`As many Achanges could be madein the above described 'constructions and `many apparently widely .different embodiments of this invention could be made without departing from the scope thereof as `defined in the following claims; it is intendedthat all matter contained in the above description or shown in the accompanying drawing shall -be interpreted as illustrative and not in alimiting sense.
