Definitions

  • the present invention has for its object a several color lead holder pencil, in which the leads of each color are held in position for use by a common gripper, normally closed under the actionor" a spring which gives it a backward movement against which a button allows it to be shifted into another position, i. e. to open it.
  • the various leads are diposed in longitudinal grooves of a cylindrical support, the axis of which is parallel but excentrical with that of the body of the lead holder pencil, so that owning to the rotative movement of the button which works the gripper it is possible to bring successively each lead into the axis of the lead holder, coinciding with a channel so that the lead falls into the opened gripper and is held there to be used for Writing.
  • the annexed drawing shows an embodiment of the object of the invention, given by way of example, and another' improved construction.
  • Fig. l is a longitudinal axial cross section of the represented lead-holder pencil.
  • Fig. 2 shows a part of this same sectional view, but enlarged, with supplementary means constituting an improvement.
  • Fig. 3 is a corresponding detail View.
  • Fig. 4 is a cross section on IV-IV of Fig. l.
  • Fig; 5 is a cross section on V-V of Fig.Y 1.
  • Fig. 6 is a cross section on VI-VI of Fig. 1.
  • Fig. '7 is a cross section on VII-VII of Fig. 1.
  • the multi-color lead holder pencil shown in the drawing consists ⁇ primarily of a sleeve I having anfouter hexagonal shape which ends at the lower end thereof in a cone shaped portion 2. Extending through the cone shaped' portion 2 is a small cylindrical bore which leads to another cylindrical bore of aV larger diameter than the rst mentioned bore, and extends through the entire upper portion of the sleeve.
  • a tube 5 having a bore 8 which is eccentrically located with regard to the longitudinal axis of the sleeve l.
  • This bore 8 communicates with a smaller bore 'I which is concentrically located with regard to the axis of the sleeve I. 1 is provided with a thread engaging a correspondingly threaded portion 'I of a gripper 3 adapted to grip and hold a lead.
  • This gripper has a cone shaped portion which is usually engaged by the inner walls of the bore provided in the cone shaped portion 2 Vof sleeve I and having of a spring ⁇ li, the lower endl of which abuts ⁇ a The lower end of the bore 2 shoulder 2' provided in the sleeve I.
  • the spring 6 continuouslyurges the tube 5 upwardly, thereby drawing the gripper 3 inwardly and forcing the cone shapedand split end of the gripper together so that it will rmly hold the lead.
  • the gripper 3 also moves down'- wardly so that it will protrude further from the cone shaped portion 2 of the sleeve I, thereby allowing the split end of the gripper by its own spring action to open so thatit will release the lead.
  • Grippers opening and closing in this manner are well known, and the gripper 3 itself does not form a part of this invention.
  • a holder 9 Rotatably mounted in the bore 8 is a holder 9 with four longitudinal radially extending ribs leaving therebetween grooves to receive four leads. These leads are kept imprisoned between the cylindrical: inner wall of the bore 8 and the four ribs. The profile of these parts appears clearly in the cross 'sectional' views of Figs. 6 and '7.
  • each of the leads may be brought one after the other into alignment with the axis of the channel 1, through which the lead can now freelyfall into the gripper 3 and com into the writing position I2.
  • the tube 5 must be prevented from turning, but without hindering it from sliding axially. This result is obtained by the cooperation of' pin I3 and of a corresponding longitudinal lateral groove I4 in the said tube 5.
  • the tube must be able to be pushed forward and to make the holder 9 turn with the least possible means.
  • This result is obtained by means of a plunger I5, which has a cavity I6 therein closed by a knob I'I forming the uppermost end of the lead holder pencil.
  • the lower end vof the plunger I5 slidably engages a portion oi the upper end of sleeve I, and it will be obvious that by pressing upon the knob I'I, the plunger I5 will push the holder 5 downwardly, thereby causing the gripper 3 to open.
  • the lower end of the plunger I5 is provided with inner teeth I8 meshing with the teeth I9 provided on the outside oi the upper end of the holder l9.
  • the holder 9 may be turned so as to bring each of the longitudinal grooves in holder 9 into alignment with the bore 7.
  • Fig. 6 shows how the above mentioned elements constitute a kind of locking device destined to immobiiize the holder 9 in each of its four positions in which a lead may fall into the gripper.
  • the four ribs of the holder 9 are notched in order to receive a ring 22. which serves as an abutment for the leads.
  • plunger I5 has eight small'recesses 23 disposed yon its outside and adapted to register with a window 24 of sleeve I.
  • the recesses contain colored Yplates which appear in turn at the window, and correspond to the color of the respective lead which in the respective position of the plunger I5 would be able to enter the gripper 3.
  • the relationship between the teeth I8 and the teeth I9 is such that one-eighth of a turn of the plunger I5 causes the holder 9 to rotate by twice the same angle, i. e., by 90.
  • a recess 23 registers with the window 24
  • one of the four compartments in holder 9 registers With the bore l.
  • the' gripper In order to ll the described pencil, the' gripper must be held upward. Then the holder is given each time a quarter of a turn by turning plunger I5 by 45, whereupon the gripper is opened, and the leads are introduced into the pencil through the open gripper.
  • the pencil is also held gripper upward and the holder is turned until the desired color appears in'the window 24. Only then the pencil is turned gripper downwards. thus making the chosen lead fall through the channel 'l into the gripper 3. The return of the lead into the holder is effected by opening the gripper the pencil being now held with the gripper upwards.
  • a small block 25 is disposed in the interior of the sleeve I in the neighborhood of ball 20. It will be recalled that the tube 5 can occupy only three distinct positions, namely the forward position with the gripper empty and open, the rearward position with an empty and closed gripper, and nally an intermediate position (as represented) when a lead has been introduced and is held in the gripper.
  • the small block 25 By suitably disposing the small block 25, it isl easy Vto ensure that it will be in front of the spring 2
  • the block By preventing therraising of the spring, the block prevents the withdrawal of ball 20 from the respective compartment of the holder 9 and thus prevents rotation of the holder 9.
  • the rotative movement of holder 9 can therefore only be effected in its rearward position, i. e. when the gripper is empty and block 25 does not block the spring 2
  • FIG. 2 The enlarged cross sectional view of Fig. 2, showing the sleeve I constituting the body of the pencil, the tube 5a which is somewhat modified over tube 5 of Figure l, the holder 9, the ball 20 with the at spring 2
  • In the neighborhood of ball 2
  • the plunger I5 may be retained in the sleeve in any desired manner
