Definitions

  • rIhe object of this invention is to provide an improved fountain constructed to overcome these defects and in which the operating meniber directly acting on the closure flap is temporarily coupled by means of a yieldable stop to a part of the fountain pen barrel on which the protecting sleeve carrying the flap is slidable, so that the operating-member is caused to actuate the lap or closure.
  • the invention consists in the construction
  • Figure l is a longitudinal section of the front portion of a fountain pen embodying my improvements.
  • Figure 2 is an elevation of the .guideway provided with a yieldable stop in accordance with one form of the invention.
  • Figure 3 is a sectional View of the same, also showing the operating rod and its stop device.
  • Fig and 5 are Views similar to Figures 2 and 8, showing slight-ly different forms of the stop devices.
  • the fountain pen here shown carries slidably mounted on its barrel 1 a protection sleeve 2 having a flap 3 for closing the exit opening'for the pen.
  • An operating rod 4 is pivoted to a point of the lap spaced lfrom its hinge and said rod has a reenforcement forming a stop device 5 tapering upwardly and downwardly and extending into a guide provided on the barrel.
  • This guide is preferabiy a tube of sliglitdiameter having a spring tongue 7, which tongue projects into the tube.
  • the reenforcement stop device 5 By sliding the sleeve 2 downwardly on barrel 1 to make the writing pen ready for writing, the reenforcement stop device 5 meets the spring tongue 7 and therebyencounters frictional yielding resistance, which causes the lla 3 to be'opened by the rod before it is reac ed by the writing pen. After the flap has been completely opened, the reenforcement stop 5 overcomes the resistance of the 'tongue 7 and passes beyond said tongue into the lower portion of the guide in which the reenforcement stop 5 is freely slidable.
  • the reenforcement 5 can be made yieldable by means of slots in which case the guide 6 1s narrowed near its upper end at l0, as shown in Figure 5.
  • a pen barrel a protecting sleeve for the pen slidable on the barrel and having a pivoted closure at its outer end, an operating rod for the closure, and coacting means, on the barrel and on the rod, to temporarily resist relative movement between the sleeve and the barrel and thereby cause the rod to operate the closure.
  • a pen barrel having a guideway, a rotecting sleeve for the pen sldable on the arrel and having a pivoted closure at its outer end, an o erating rod for the closure movable longitudlnally in the guildeway, and coacting means on the rod and in the guideway, to temporarily resist movement of the rod in the guideway and thereby cause the rod to 0perate the closure.
