Definitions

  • the present invention relates to improvements in fountain pens, and more particularly to that type of pen which has ball nib, and in which the pen proper is mounted within the barrel to be moved longitudinally to be housed when not in use and be projected outwardly for use, one
  • object of the invention being the provision of afountain pen having a readily accessible manually operated means for projecting the pen and for releasing the same.
  • Another object of the present invention is the provision of a novel combination of elements so disposed as to project and lock a spring retracted main pen element, and by a similar movement to release the lock to permit the main pen element to automatically retract.
  • Figure 1 is a longitudinal section through the barrel with the main pen element in side elevation and in projected position the complete pen being broken intermediate of its ends.
  • Figure 2 is a similar view with the main pen element in retracted position.
  • Figure 3 is a section on line 3-3 of Fig. 2.
  • Figure 4 is a section on line 4-4 of Fig. 2.
  • Figure 5 is a section on line 5-5 of Fig. 2.
  • Figures 6 and 7 are detail views of the actuating member or cylinder.
  • FIGS 8 and 9 are details of the main pen element lock.
  • the numeral l0 designates the barrel or carrying member having the open truncated end ll, said member being constructed tubular in shape with both ends open.
  • the main pen element I 2 Insertible through the enlarged open end of the barrel, is the main pen element I 2, which constitutes a writing paste container having the outlet tube IS with the removable ball nib member ll.
  • an inwardly projecting ring i 5 Within the barrel at a point adjacent to the junction of the main portion and end II is an inwardly projecting ring i 5, which forms a shoulder against which the upper end of the coil extension spring l6 abuts, while it surrounds the tube I 3 and has its lower end abutting the upper end of the barrel portion of the pen 12. This spring tends to hold the pen in retracted position as shown.
  • a sleeve 11 fits snugly as a plug in the enlarged end of the barrel l0, and is held against rotation therein through the medium of the screw I8 mounted in the aligned screw threaded openings l9 and 20, of the respective sleeve and barrel.
  • an operating member or cylindrical piece 22 Slidably mounted in the bore 2
  • a slot 24 is provided in the wall of the socket of the operating member 22, while a pin 25 carried by the cylinder 25 rides in said slot.
  • alocking device which consists of a supporting portion 21, having the spring terminal 28 having a hook 29, which has a, tension to engage the wall of the member I2, and when it has been pushed outwardly by the members 22 and 25 to the dot-anddash position Fig. 2, will snap below the bottom.
  • the spring 25' is of such tension that when the operating member 22 is pushed inwardly, the member 25 engages and pushes the main pen member against its spring It, without compressing the spring 25', so that the lock releasing device 30 carried by the member 22 is not brought in to play.
  • the member 22 when released will be moved rearwardly so that its extended end will be in ready position to be pressed inwardly for the releasing operation.
  • the member 22 is the sole means for projecting the pen in to writing position and for releasing its lock, to permit the pen to assume encased retracted position.
  • the end 32 of the locking device 21 fits in a recess of the plug sleeve l1, and the greater portion of its length lies in a longitudinal recess in the inner wall of the barrel, while the locking releaser 30 is fitted and attached to the operating member 22, making all parts easily and quickly assembled and taken apart, as all elements are insertible through the enlarged end of the barrel HI, and held in place therein by the screw l8.
  • a fountain p n including in combination, a main tubular barrel open at both ends, and one end being conical in shape, a main pen body slidably mounted in the barrel and having a ball nib adjacent the conical end oi the barrel for projection through said conical end, a spring for normally holding the pen retracted with the ball nib within the barrel, a longitudinally slidable manually operable member mountedin the enlarged open end of the barrel and having its inner end engaging the inner end of the main pen body, whereby the pen is moved into writing position with the ball nib extended out through the conical end of the barrel, a spring lock for holding the main pen body so projected, and means carried by the manually operable member for releasing the lock to permit the spring to move the nib back into the barrel.
  • a fountain pen includingin combination, a main carrying barrel open at both ends, one end being in the sha e of a truncated cone, a main pen body mounted for longitudinal sliding movement within the barrel and having a ballpen nib adjacent the truncated end of the barrel for movement exteriorly and internally of the barrel, a spring for holding the main pen body retracted and housed within the barrel, a two sectioned operating member mounted in the end of the barrel remote from the truncated end and haying its inner end in contact with the inner end of the main pen body and its other end exteriorly of the barrel, a spring lock mounted in the barrel and having a hooked terminal in the path to engage and hold the main pen body in projected writing position when the operating member hasbeen pushed inwardly to project the main pen body, and means carried by the operating member to release the spring lock to permit the first spring to move the main pen body to retracted position.
  • a fountain pen as claimed in claim 4 wherein the two sectioned operating member is provided with a spring to hold the section apart,
