'l h'lS lnVGQi-l-Gn relates to fountain pens such asare carried in a pocket about ones person, and the" primary object of this in vention is'to provide certain new and useful improvementsinwriting implements of this character.
r Another object of this invention is to provide a certain new and novel means whereby the pen may be easily and readily tilled.
Theinvention broadly consists in the provision of a plunger or piston operable in the barrel ofthe fountain pen for forming suction t'o -dra'w the ink or fluid from the con tainer into the' barrel tirough the conventional nib stock of the fountain pen.
A still further object of the invention is to provide a fountain penof this character wherein the means for actuating the piston is in the nature of a rack and pinion.
Other objects and advantages of the inven tion is to provide a pen of-this character which is comparatively simple, in construction, economical, thoroughly practical, ellicient, reliable in use and operable.
Other objects and advantages of the invention will become apparent during a study of the following description, taken in connection with the accompanying drawings, wherein Figure 1 is a longitudinal sectional view with certain parts broken away, through the (Y en, the protector cap being shown in position. when the pen is not in use.
Figure 2 is a view taken at right angles to Figure 1 and showing the protector cap positioned as when the pen is in use.
Figure 3 is a longitudinal sectional view through the pen showing the suction piston the beginning of its suction stroke.
Figure 4 is a perspective view of the pis ton and actuating means therefor.
Figure 5 is a horizontal transverse sectional view taken substantially on the line 5-5 of Figure 3 on the direction of the arlOVS.
lVith reference more in detail to the drawings, it will be seen that the fountain pen as comprehended by the present invention comprises the usual barrel 5 provided at its lower tapered end with the conventional nib stock 6 suitably threaded in the lower end of the barrel as at 7. The nib stock carries the usual pen 8. Mounted for reciprocation in the barrel ,5 is a tubular member 9 having suitably secured thereto at the bottom end there- .of a piston 10. Integral with and extending upwardly from the other end of the tubular member 9is a rack bar 11. The rack bar 11 is movable longitudinally between the adja cent ends of a pair of suitable shaped combined bearing and guide members 12-12 internally arranged in the upper end of the barrel 5 at diametrically opposite side of the barrel. Journaled in the bearing 12 and extending transversely of the barrel 5 is a shaft 13 upon which is rotatably mounted a pinion 1i meshing with the teeth of the'rack bar 11 as clearly shown to advantage in Figure 3.
An externally threaded knob 15 is provided with a cylindrical extension 17 forming a shoulder 18. The tubular extension 17 is adapted forcslidable movement into and out of the upper open end of the barrel 5, the
Furthermore, it is to be noted that th diametrically opposite sides thereof is provided with integral lugs 22 engageable in tubular extension 17 on the side diametrically H opposite to the rack bar 18 is provided with notches 23 formed on the upper edge of the barrel 5 for retaining the movable parts against casual displacement when the barrel is filled with ink or writing fluid.
The operation of the pen for filling purposes may be briefly explained as follows To fill the pen the parts are in that position shown to advantage in Figure 3, that is with the piston at the lowermost end of the barrel 5 and the knob 15 pulled out of the adjacent end of the barrel. Obviously, by pushing inwardly on the knob 15 the resultant movement to the rack 18 meshing with the pinion 14 will rotate the pinion thus imparting an upward movement to the rack 11 with which the pinion 14 is in mesh thus drawing the piston upwardly in the barrel creating a suitable suction through the bore of the nib stock 6 for drawing the ink through the bore of the nib stock into the barrel. At the completion of the Lip-stroke of the piston the parts are in-that position shown in Figures 1 and 2,- that is, with the shoulder 18 abutting the upper edge of the barrel. 5 and the racks 11 and 18' received in the notches 19 and 20. Asuitable protector cap 24 for the pen 8 may be then disposed over the nib stock in a manner clearly suggested in Figure 1 when the penis not in use. When the pen is in use theprote'ctor cap 24 may be disposed over the top portion of the barrel 5 as shown to advantage in Figure 2, and in this connection lh'Wlll be notedthat the cap24 at its closed end is providedavith integral threads 25 complemental to the threads on the knob 15 for engagement therewith when the cap is in the last referred to position. FIO111 the foregoing then it will be seen that I have devised a novel, yet thoroughly practical and'efiicient fountain pen wherein the filling means is very simple in its construction, handy to operate and otherwise affording a d- -vantages in fountain pens heretofore lacking I wish to claim as new is 1. A fountain pen comprising a barrel, a nib stock at the lower end of the barrel, a piston mounted for reciprocatory movement within the barrel, a rack bar integral with the piston, a pinion rotatably mounted in the barrel above said piston meshing with said rack bar, a plug insertable in the other ,end ofthe barrel for normally closing said barrel, and a second rack bar integral with said plug for meshing with said pinion whereby when said plug and last mentioned rack is moved in one direction the first menend of the barrel for normally closing said barrel, and a second rack bar integral with said plug for meshing with said pinion whereby when said plug and last mentioned rack is moved in one direction the first mentioned rack bar will be moved in an opposite direction, and guide means for said rack bars, and located in the barrel.
3. A fountain pen comprising a barrel, a nib stock at the end of said barrel, a piston mounted for reciprocatory motion within the barrel, a rack bar integral with the piston, a pinion rotatably mountedin the barrel above said piston and meshing with said rack bar, a screw threaded plug insertable in the other end of the barrel and a rack bar integral therewith and meshing with said pinion whereby when said last mentioned rack bar is moved in one direction the first mentioned rack bar will be moved in an opposite direction, and guide means integral
