Description

Patented Mar. 30, 1948 INK PASTE CARTRIDGE FOR BALL POINT FOUNTAIN PENS David Pelton Moore, Forest Hills, N. Y., assignor to Premium Merchandising Corporation, a corporation of New York Application June 7, 1945, Serial No. 597,999
1 Claim.
The present invention relates to improvements in ink paste cartridge for ball point fountain pens, one object of the present invention being the provision of a detachable ink paste cartridge, whereby a new one can be substituted for the empty or used one.
Another object of the present invention is the provision of a novel form of cartridge and feed bodily carried thereby where a compression conical coiled springis employed to act upon a floating piston or plunger to exert suflicient and proper pressure upon the ink paste to extrude it properly into the ball chamber, the ball acting as a medium to prevent undue flow of the paste when the pen is at rest.
In order that the invention may be fully understood and therefor its advantages appreciated, attention is invited to the accompanying drawings, in which- Figure 1 is a longitudinal section taken on a median line of a complete pen made in accordance with this invention, the piston being in one retracted position.
Figure 2 is a longitudinal section of the loaded cartridge per se with the piston nearest its extreme expelling position with the spring extended.
Figure 3 is a section on a very much enlarged scale of the closure member with the adjacent part of a cartridge.
Figure 4 is a side elevation of the seal piercer.
Figure 5 is a plan view of the piercer from below.
Figure 6 is a section on line 6-6 of Fig. 1.
Figure 7 is a section on line ll of Fig. 1.
Referring to the drawings, the numeral l0 designates a closure member, here shown as bein provided with a bore H, a threaded bore 13 and an enlarged bore M, the purposes of which will presently appear. This member has an apron M, to which is threadingly attached at 15 a barrel IS.
A metal tubular member I! provides a means to attach a cartridge, carry a ball point and convey the ink paste from the cartridge to the ball point, and has formed a longitudinal duct l3 therethrough, the lower end of which is slightly flared. This duct leads the ink paste from the cartridge 26 to a ball point in the usual manner.
The member I1 is also provided with a threaded portion 23 to cooperate with the threaded portion 13 of the member ID, and an enlarged head 22, which fits in the bore l3 of the member W.
In order that a cartridge 26 may be detachably connected to the member [1, an internally threaded bore 24 is provided in the head 22, and is in communication with the flared end of the ink paste duct 18, the threaded attaching member 25 of the ink paste cartridge 26, being screwed therein and during such action havin its usual metal seal 25' pierced by the seal piercer 27. This piercer consists of the supporting disc 21' having four cutter blades 28, which, as the cartridge is rotated to connect the same to the member ll, causes the seal to be cut and bent from the centre outwardly so that the ink is then free to move or pass through the apertures 28 of the piercer to the ball point, as illustrated in Fig. 1.
In order that proper pressure may be exerted upon the ink paste contained in the cartridge, after the ink paste has been introduced from the lower end of the cartridge, a floating piston or plunger 30 is inserted through such open end to abut the ink paste, the conical extension spring Si is then inserted to contact the piston, and the screw cap 32 is seated as shown in Fig. 1, so that the action of the spring in tending to extend will cause the piston to move and press the ink to extrude same for writing purposes. The strength of this spring is such that a steady low pressure is exerted, and no undue extrusion of the ink paste in and through the chamber 19 occurs.
It is evident that by providing this type of spring and piston feed that various springs of different tension may be employed in accordance with the viscosity of the ink paste used.
What is claimed is:
An ink paste cartridge for ball-nib fountain pens, consisting of a tubular casing having a reduced externally threaded outlet and an internally threaded portion at the opposite end, a soft metal seal at the reduced outlet, an externally threaded plug fitted in the internally threaded portion of the casing, a floating piston mounted in the casing, and an extension spring disposed between the plug and the piston to exert pressure against the piston to create pressure upon the ink paste within the casing.
DAVID PELTON MOORE.
