Definitions

  • Chief object of the invention is the provision of an improved pencil in which the lead feeding mechanism is connected to a push-button constituting the body of the pencil clip, said clip being movable relatively to the pencil head and said head being stationary with respect to the pencil body.
  • Fig. 1 is an external-side view "of a pencil-in accordance with the invention
  • I L 1 Fig. 2 is a fragmentary front view, of the embodiment illustrated in Fig. 1;
  • Fig. 3 is a partial longitudinal sectional view on a larger scale taken along theline 33 of Fig. 2;
  • threaded portion of the body is extended by an ornamented ring.
  • the upper or rear end of the head 3 is, for

  • the incision 5 extends preferably at 6 (Fig. 3) beyond the solid portion to the tubular portion of the head 3 where said incision opens laterally.
  • the push-button 1 is provided on its edge 8 located in the bottom of the incision 5 with a tapped hole 9" for receiving a threaded pin I0; Said pin is integral with or fixed to the bottom of an inner tube II slidably mounted inside the head 3. Said tube II covers the usual tube I2 forming a lead-reservoir which controls the feed mechanism by means of its longitudinal displacements. Tube II bears against tube I2 through ashoulderl3.
  • tubes II and I2 is arranged so as not to impede the separation, through unscrewing at 2, of the body I, with its tube I2 and, on the other hand, of the whole head assembly with the devices above described.
  • the clip body or push-button 1 preferably has itsedge 8 provided with a slot I4 for engagement with the bottom of slot 6 of the head 3 upon completion of the displacement of push-button I and clip 1 towards the tip of the pencil, that is, in the direction of arrow ,f (Fig. 3) relatively to the head 3.
