SU80986A1 - Automatic pen for liquid ink with a ball as a writing tip. - Google Patents

Description

Known automatic pens, having a ball as a writing spike and designed to use special ink or paste with a continuous supply of ink to the food ball.

The proposed automatic pen provides the possibility of using ordinary liquid ink therein and supplying them to the squeezing ball during writing, by applying a spring-loaded cone valve regulating the supply of ink and interacting with a pin with a ball having the ability to move along the axis of the pen.

The drawing schematically shows the handle in longitudinal section.

The automatic handle consists of a body 11, closed at one end by a lid 8 with a tip / and a spring 2, & with another tailpiece 13 protecting the pipette 14.

The body // is connected to the sleeve 9 of the tip 6. The writing tip is a ball 3, abutting against the pin 4 of the cone valve 5, having the possibility of axial movement. The valve serves as a stop for the tube 5, and carrying the nut 7 for adjusting the spring 15.

The ink set is not made through the feeding mechanism (i.e., into the gap between the ball and the walls), but through the opening 16 in the coupling 9, through the annular groove at the end of the coupling .2 and through the capillary opening of the tube 12 inserted into the nut 10, interior of the housing 11.

The housing 11 is filled with the principle of pushing air out of the inside of the housing // when pressure is applied to the plummet 14, as a result of which vacuum is created in the housing 11 and it is filled with ink under atmospheric pressure.

When typing ink, unscrew the tail plug 13, expose the pipette 14, lower tip 6 into the ink so that the gap

No. 80986-2 between the clutch 9 ir body 11, where the hole 16 goes, was injected into the ink.

After the ink is collected, the pen can be in any position and the ink will not come out, since the atmospheric pressure in the capillary orifice and the molecular adhesion of the ink will allow the ink to penetrate into the tube / 2.

The work of the writing mechanism is as follows: the ink enters through the opening of the coupling 9 n under the tip 6, then through the slots in the nut 7 flows to the cone valve 5, where it closes, as the valve closes the opening under the action of the spring / 5 the tip. In the press, due to pressure on the ball 3, the valve 5 rises, squeezing the spring 15. The hole opens, and the ink between the walls of the tip 6 and the pin 4 falls on the ball, which is covered with ink and applies them to the paper. After cessation of pressure on the ball 3, the spring / 5 is unclenched, presses on the clanan 5 and puts it in place, stopping ink access to the ball.

The spring 15 is in the compressed state between the nut 7 and the clanan 5 n and allows movement of the valve as well as the valve by 0.3-0.5 mm.

Claims (2)

1. An automatic liquid ink pen with a ball as a writing tip, consisting of a tubular body-tank having a tip with a writing ball, a pipette for filling and a capillary air discharge tube, characterized in that, in order to supply ink to the ball only in the process of writing, the ball is mounted in the tip together with the axially movable and spring-loaded conical clan, the interacting pin with the ball and intended to regulate the ink supply. 2. The automatic pen according to claim 1, wherein a capillary air vent tube is used to fill the reservoir with ink.
