Definitions
- the present invention relates to writing devices and particularly to ball point pens of the multiple writing unit type.
- Such pens are primarily used with writing units charged with ink of dilferent colors to give a quick color-change in use but they may also be used with units charged with the same ink so that when one unit is eX- hausted, another can be brought quickly into operation.
- a ball point pen of the multiple writing unit type having for each writing unit a pusher which is spring biased from an engaged operative position towards the retracted position, in which pen each pusher is provided with a ramp adapted, when the pusher is advanced while another pusher is engaged, to disengage the other pusher and thereby cause it to be spring driven to its retracted position.
- each pusher In the operation of the pen each pusher is engaged when the point of its writing unit projects in the writing position at the end of the pen and is released for return to its retracted position when another pusher is moved from its own retracted position. Further movement of the other pusher brings the new ball point into the writing position.
- each pusher consists of a head part upon which the ramp is formed and a rod part which passes through a helical spring which provides the spring bias for the pusher.
- a transversely displaceable ball which serves to convey the disengaging reaction of the ramps from one pusher to the other.
- the pushers are formed with recesses which are penetrated by the ball when the pushers are in the retracted position, said recesses being bounded by the ramps.
- a guide member for the pusher is mounted on the axis of the pen and provides an abutment for restraining the pushers in the engaged position.
- the guide member is grooved or slotted to accommodate the ramps as the pushers are advanced.
- FIG. 1 is a part-sectional elevation of a preferred form of the present invention designed for two writing units with one ball point in the writing position and the other retracted;
- FIG. 2 is a view similar to FIG. 1 with both ball points retracted.
- the pen has two writing units a and :1 arranged symmetrically about its longi- 3,301,221 Patented Jan. 31, 1 967 tudinal axis.
- the pen may be modified to have more than two units, for example three spaced apart by The units are mounted in the body I) of the pen, which has a separately formed cap c.
- Each unit is fitted to the rod part d of a pusher, slidably carried in a fixed guide plug e, formed with internally shouldered channels e and fixed, for example, to the body of the pen. Threaded over each rod part is a spring 1 which bears against the base g of a pusher head g and against the shoulders of the channels 2 by means of which the pushers slide in the ring 2.
- Two cavities h are adapted to receive the heads g. of the pushers which abut in the retracted position against the shoulder I1
- These heads move along a median partition i.
- the lower part of this partition forms a stop for the forward portion of the heads.
- the head g has a recess m, bounded by a ramp portion m
- An aperture n is formed centrally through the forward part of the partition i of the cap of the pen at the retracted level of the notches m of the heads g.
- a ball 0 which, as may be seen from the drawings, is displaceable transversely to the axis of the pen.
- a writing device comprising a casing; a plurality of elongated writing units; said writing units being mounted in said casing for axial movement along the axis of said casing and being separately movable between a writing position and a retracted position in said casing; spring means biasing each Writing unit to its retracted position in said casing; abutment means fixed longitudinally relative to said casing and positioned between said writing units; locking means on each of said writing units engageable by said abutment means when said writing units are moved into their writing positions for restraining said units against retraction by said spring means; a spherical member; guide means fixed relative to said casing and positioned between said writing units; said spherical member being supported by said guide means and being capable of movement transversely with respect to the longitudinal axis of said casing; and camrning means integrally formed on each writing unit; the camming means of one of said writing units cooperating directly with said spherical member upon movement of said one writing unit from its
- each of said writing units is provided with a recess one wall of which serves as said camming means; said spherical mernher being movable at least partially into the recess of one of said writing units in its retracted position when another of said writing units is moved from its retracted position toward its writing position.
