WRITING PEN Filed April 8, 1935 Patented Mar. 10, 1936 UNITED STATES PATENT OFFICE 13 Claims.

This invention relates to pens, and particularly to a type of pens, in the use of which, considerable pressure is frequently exerted on the writing end thereof, as, for example, in the use of stylographic pens which are used and are especially well adapted for making carbon copies of original writings.

One object of the present invention is to provide a construction and arrangement whereby portions of the pen are protected against scooping up dust, dirt, paper fibers and the like, which tend to clog the ink passage and seriously interfere with the eflicient operation of the pen.

Another object of the invention is to provide a stiff non-spreading pen point capable of receiving pressures suitable for producing carbon copies.

Another object of the invention is to provide a construction and arrangement wherein the pen point member is rigidly mounted in the nozzle portion of the pen, and wherein the discharge opening for the ink is positively and automatically determined.

A further object of the invention is to provide a structure wherein clogging of the ink within the pen is overcome and an efficient flow of the ink assured.

A still further object of the invention is to improve devices of the character described in sundry details hereinafter referred to and particularly pointed out in the appended claims.

An embodiment of the present invention is shown for illustrative purposes in the accompanying drawing, in which:

Fig. 1 is an elevational view partly in section of a pen embodying features of the present invention;

Fig. 2 is an enlarged fragmentary longitudinal sectional elevational view of the lower end portion of the structure illustrated in Fig. 1 and taken substantially as indicated by the line 2-2 thereof;

Fig. 3 is a transverse sectional plan view taken as indicated by the line 3-3 of Fig. 2;

Fig. l is a further enlarged fragmentary sectional elevational view of the structure adjacent the lower end portion of Fig. 2;

Fig. 5 is a plan sectional view taken as indicated by the line 5-5 of Fig. 4;

Fig. 6 is an enlarged fragmentary sectional elevational view similar to Fig. 4, and illustrating a slightly modified form of the structure embodied therein; and

Fig. 7 is a bottom plan sectional view taken as indicated by the line 7-? of Fig. 6.

As illustrated, particularly in Figs. 1 to 5, inclusive, of the drawing, the present invention comprises a body portion, indicated as a whole by the numeral ll, consisting of a hollow tubular barrel l2 having a bulb l3 formed of rubber or other suitable flexible and resilient material positioned in one end of the barrel l2, and a nozzle, indicated as a Whole by the numeral I4, positioned in the opposite end thereof, the said nozzle being shown, in the present instance, as comprising a tapered portion l5 formed, preferably, of a suitable translucent material, such, for example, as glass or the like and having a tubular shell or sleeve l6 positioned therein and extending beyond the outer end thereof, the said barrel l2 and nozzle l4 providing a container or reservoir I"! for maintaining a supply of ink within the devlce'for writing purposes.

Removably mounted in the sleeve l6 and extending therethrough into the interior of the body portion H is a tubular member, indicated as a whole by the numeral l8, and provided'w'lth a plurality of annularly spaced lugs or enlarged portions l9 adapted to frictionally engage the inner surface of the sleeve IS in a manner to rigidly secure the tubular member l8 therein and in spaced relation with respect thereto in'a manner to form an annular ink channel 2| communicating at its upper end with the lower end of the reservoir H, the member l8 being also readily removable from the sleeve l6 for the purposes of cleaning. p

For preventing a filtering action of the ink and eliminating clogging at the point where the reservoir I! empties into the channel 2|, the cross-sectional area of the channel is increased, the increasing of the area of the channel being obtained, in the present instance,=by providing the tubular member IS with a reduced outer diameter, indicated at 22, adjacent the lower end 01' the reservoir I1.

Formed on the lower or outer end of the tubular member I8 is a laterally extending annular flange portion, indicated as-a whole by the numeral 23, the flange, in the present instance, extending outwardly in a manner to overlie a portion of the outer end of the sleeve 16 to prevent unintentional free flow of the ink, the flange 23 being provided adjacent its edge with a plurality of beveled portions 24 which may be of various lengths and with a plurality of lugs 25 between said beveled portions adapted to engage the adjacent end of the sleeve IS in a manner to deflnitely and automatically position the flange 25 with respect to the sleeve 16 and space the beveled portions 24 from the end of the sleeve 16 to provide a discharge outlet of suitable dimensions at and communicating with the ink channel 2|.

for passing the ink therefrom.

While the present illustrative embodiment of the invention discloses three bevel surfaces 24 and three lugs 25, it will be obvious that more for positioning the flange 23 with respect to the end of the sleeve I6.

It will be noted that the tubular member I8 is provided with a longitudinally disposed air vent and filler opening 26 formed therein and extending therethrough to permit of the admission of air into the interior of the body portion II and reservoir I! to replace the ink removed therefrom during the writing operation of the pen, and providing also, an intake passage through which ink may be drawn into the pen during the filling operation by manipulation of the bulb Hi, the ink during the filling operation being discharged from the upper or inner end 01 the opening 26 into the reservoir H.

In the embodiment illustrated in Figs. 6 and '7, a tubular member 18a isprovided with a laterally extending annular flange 23a' having a substantiallyflat upper surface 23b, and adjacent the flange 23a is a sleeve [6a having a plurality of annular beveled portions I61) and a plurality of lugs [60 positioned between the beveled portions and adapted to engage the upper surface 236 of the flange 23a for positively and definitely positioning the flange with respect to the sleeve [6a, and for maintaining the flange in properly spaced relation with respect to the beveled portions I612 for providing an outlet of suitable dimensions at and communicating with the discharge end of an ink channel Zia.

It will be observed from the foregoing description that by reason of the overlying relationship of the flange 23 with respect to the sleeve l6 that the present arrangement protectsthe tip of the nozzle portion or element against scooping up dust, dirt, paper fibers and the like, which tend to clog the flow of theink, and that the invention also provides a non-spreading pen point suitable for pressures for producing carbon copies.

It will be observed also that the present invention provides a novel construction and arrangement whereby the outlet for the ink from the channel 2| is positively and? automatically determined, and that by reason of the increased cross-sectional diameter of the ink channel 2| at the discharge end of the reservoir l1,- clogging of the ink within the pen is overcome and. an efficient flow of the ink is assured.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same' may be variously modified. Moreover, all of the features of the invention need not be used conjointly' a-sthe same may be used to advantage in variously different combinations and sub-combinations.
