Application med February 17, 1923, Serial ll'o. 619,625. Renewed October 10, 1927.

tainer to the feed, the seal .is broken and the ink fed to the pen feed; to provide a container which on insertion into the en barrel and attachment to the en fee is first sealed thereto prior to its eing unctured whereby any leakage or fouling o the inner barrel is prevented; to provide containers which are rigid in form and ractically indestructible, and receptacles which are especially adapted to be used in traveling, as the ink is sealed in the liquid-tight containers, Which are not easily broken.

Fig. l is a view of the metal tube used for making the container. Fig. 2 shows the bottom sealing cap ready to be inserted in the tube. it has been grooved near the open end to receive the seal, with a displacement peg in the tube for removing the excess ink. Fig. 4. is a view of the. tube showing the seal to be placed in the upper open end of the tube or cartridge after filling. Fig. 5 is avie'w of the tube partly in section with. the seal in place. Fig. 6 is an enlarged detail sectional view ofthe seal. Fig. 7 is a cross sectional view through the feed end of a pen illustrating a cartridge in position.

Referring to the drawings, at 1 is shown a drawn metal tube which is cut in desired lengths, the4 thickness of the metal ranging from .003 to .O07 inches. Normally, the gauge will be substantially .004 of an inch for the tubes used in connection with these cartridges, although this thickness may be varied as desired.

The metal may be either copper, aluminum, brass or numerous other alloys which can be drawn to this thickness.

These tubes are first cleaned with a solution which removes any dirt or grit from the inner and outer surfaces. Into the bottom of the tubes are then inserted caps 3' which have a narrow upturned edge 4. These Fig. 3 is a view ofthe tube after may be plugs of an i desired character which may be easily sol ered into the bottom of the cartridge. v

After the soldering o eration, the cartridges are grooved as s own at 5, which supplies a seat on the inner surface of the cartridge for sealing member shown at 6. These sealing members are die cast, molded or otherwise formed from a relativel soft metal such as lead, solder or other slmilar alloy.

After forming the groove 5 in the upper portion of the cartridge, the outer surfaces of the cartridges are dip ed in a bakelite solution. After di ping,t ey are permitted to dry for half an our, more or less and are subsequently baked at temperatures ranging from 275 upward. This bakelite coating may be substituted by dipping in other coating materials, the purpose being to coat the outer surface of the tube 0r cartridge to prevent corrosion due to the acid contained in the ink.

The cartridges after having this coating application, are internally sprayed with parafiin, wax or other hydrocarbon coating which will adhere to the inner surfaces of the cartridges, and prevent the ink from coming in contact and attacking the metallic surface. When this coating substance is dried, the tubes are filled in-a desired manner, it being essential that bubbles of air arereliminated from the tubes during the lling operation. After lling, a plurality of tubes are inserted in a rack, and displacement pegs such as those shown at 7 are inserted-into the open ends of the tubes to remove the excess ink, which will flow over the top of the cartridge and be collected in a receptacle (not shown) beneath the tubes.

r1`he seals which close the upper ends of the tubes or the ends which are inserted into the pen barrel, consist of a hollow soft metallic plug such as that shown at 6. The inner portion of the 'seal is threaded as shown at 6, and in the bottom of the seal is a scored. circular portion 6" which is vpunched out of the seal when the cartridge is screwedon to the pen feed. The cartridges arevadapted to a particular type of pen which has a threaded feed which engages the threads of the seal when the cartridge is screwed in place. On the circumference'of the seal is shaved off a narrow caps are of a similar metal to the tube, or groove as shown at 6a, which permits the escape of air from the cartridge when the seal is pressed into place on the grooved seat in the upper portion of the cartridge as shown in Iig. 5.

After the cartridges have been filled with ink, an paraine or wax coatin which re-l mains aliout the inner mouth of :Ee cartridge is removed andthe seal pres d in place against the grooves 5. g o p l To assure a liquid tight container, the hollow mouth of the tube is then spun or rolled so that the upper lips of the cartridge are turned back as shown at 8. in Fig. 6. These lipped portions are pressed or punched into the upper part of the seal, and prevent an in tween tie seal and cartridge to escape and foul the cartridge. In addition to the s inning or rolling back of these lips the al stage slightl flares the upper portion of the tube as s own in Fig. 6 so that the cartridge may be more easily inserted in the pen barrel.

To use the cartridge, it is only necessary to remove the end of the barrel shown at 9 diagrammatically, in Fig. 7 and. screw the cartridge on the threads of the pen feed shown at 10. As the cartridge is screwed in place on the pen feed, it will first form a liquid tight seal with the pen feed and then the puncturing point 11 will contact the scored portion or plug 6b and punch it in the forni of a disc out of the seal. This disc will fall into the cartridge and permitv the ink to flow readily into the feed and to the en point.

' Tiie utility of the device is readily appreciated as a cartridge may be removed and replaced by a filled cartridge as soon as the ink has been exhausted. The ink is kept in the best possible condition as it is insulated from Contact with the metal by the parafiin or wax coatin on the inner surfaces of the cartridge. T e screw seal further assures the pen against any ink fouling due to leakage of the ink from the cartridge into the en barrel. The containers are .particular y adapted for use in traveling as they may be packed with clothing without fear of soiling, and are not easily broken.

which may work its way beto the type of 4pen in which they are used.

I claim as my invention: 1. Ink cartridges comprisin substantially rigid metallic containers fille with a writing fluid and having sealed ends, one of the ends being closed b a sealin cap having a puncturable area a apted to lie pierced and through which the ink flows, anda depressed internally threaded pen feed engaging portion.

2. Ink cartridges comprising substantially rigid metallic containers filled with a writing fluid and having sealed ends, one of the ends being closed b ,a sealin cap having'a puncturable area ad7 pted to ie through which the ink flows, and a depressed internall threaded pen feed engaging por; tion, sai puncturable area of the seal being entirely removable to provide a permanent hole therein. y

3.v An ink cartridge comprising a metallic container filled with writing fluid, one end being permanently closed by a closure cap fitted into said end, and the other end being provided with an internally threaded sealing cap depressed therein and provided with an area adapted to be punctured and entirely the sealing cap to assist in retaining the seal-1 ing cap in place.
