  • ALBERT HIBTH or Human, nosmvnrzne, swIrzERLAim MAGAZINE rnncrr.
  • My invention relates to magazine pencils in which a set of lead carriers are arranged in a barrel and moved into active position by means such as a handle for each carrier, these handles projecting from slots in the barrel. It is an object of my invention to improve a pencil of the kind described. To this end I provide a spring in the barrel which is so positioned as to be engaged and compressed 0 by that carrier which is moved into' activ.e
  • Fig. 1 is a partly sectional elevation
  • Fig. 2 is an axial section
  • Fig. 3 is a section on the line IIIIII m Fig. 2, drawn to a larger scale
  • Fig. 4 is an elevation, with a portion of the magazine partly broken away, and
  • Fig. 5 is an axial section of the second type.
  • 1 is the barrel of the lead pencil which may be cy- 0 lindrical and is preferably of thin wall section
  • 2 is a tapered tip at the lower end of the barrel
  • 3 are the lead carriers
  • 4 are the leads in the carriers.
  • 24 is a magazine which is inserted in the upper end of the barrel 1
  • 12 are a pair of bayonet joints by which the magazine is detachably secured to the handle
  • 22 is a sleeve on the magazine which fits the outer wall of the barrel 1.
  • the bayonet joints may also be in the sleeve 22.
  • the carriers 3 are tubes, preferably of thin Wall section, which are contracted and slotted in the usual manner at their outer ends for resiliently engaging the leads.
  • a plunger (not shown) is inserted in each carrier and adapted to be displaced therein by screwing.
  • Each carrier is rotatably connected to I a tubular extension 8 which may be of cir cular section as shown in Figs. 1, 2 and 3,
  • Each carrier is equipped with a handle havin a pin projecting'inwardly through a slot 1% in the barrel 1, a slide 13 which is applied to the inner wall of the barrel b the inner end of the pin, as best seen in ig.3, and a spring 14 with. a catch block 36 at its lower end which is connected to the slide 13 by the pin of its handle 15, but mi ht also be made position as shown for the carrier at the left in Fig. 3.
  • the spring catch now arrests the carrier in the active position and the knob of 36 which may be of the same color with which the corresponding handle 15 is marked, projects from the hole 37 ready for opera- .tion if it is desired to return the carrier into its initial position.
  • the other carriers are not influenced by the movement of this articular carrier, means which will be described being provided for retaining them in their initial position as shown for the carrier at the right in Fig. 2.
  • 21 is an extension at the upper end of each slot 17 which is so large that the handle 15 can be pushed into the interior of the barrel for extracting the carrier and its handle after the magazine 24 has been removed. -When the magazine 24 is in position on the upper end of the handle its sleeve 22 covers the ex tensions 21.
  • 33 is a combined annular spring seat and carrier guide which is arranged at the point where the tip 2 merges into the barrel, 32 is a compression spring on the seat 33, and 34 is an annular spring plate at the upper end of the spring 32. The spring is compressed when the slide 13 of the carrier which has been moved into active position, bears on.
  • the handles 15 are channeled and provided with projecting insertions or plates in the color of the lead in the corresponding carrier 3.
  • the spring 14 pushes the block 36 into the corresponding hole 37 as described, locking the carrier in its active position.
  • the knob on the block 36 which projects from the hole is de-- pressed with one finger, the carrier is released and the spring 32 pushes it back into its initial position.
  • the magazine 24 and its outer sleeve 22 are connected by a barrel 43 which is in line with the upper end of the barrel 1, and by rivets 44.
  • a knob 42 is screwed on the upper end of the magazine 24 with a threaded extension 45.
  • 38 is the bottom of the magazine which is held by two parallel ribs and so positioned with respect to the lower end of the magazine that the heads 11 in the initial position of the carriers 3 project into the magazine 24 below the bottom 38, as shown at the right in Fig. 2.
  • the magazine 24 and the sleeve 22 obviously brace the slotted portion of the barrel on the inside and the outside in a very effective manner.
  • Means for holding the carriers 3 in their initial position may also be provided on the slots 17 and an example is illustrated in Figs. 4 and 5.
  • Each slot has a pair of inwardly projecting lugs 40 in such position that the pin of the corresponding handle 15 overcomes the resilient resistance of, and is retained by, the lugs returning into their initial position after having been moved apart by the pin.
  • tubular extensions 8 of the carriers 3 which are of square section in this instance and without the heads 11 illustrated in Figs. 1 to 3, here engage an inverted hollow taper 41 at the lower end of the magazine 24.
  • the handle 15, with its pin held in the slot 17, acts like a pivot for a double-armed rocking lever so that the lower end of the carrier 3 is applied to the seat 33 or the tip 2 at slight pressure.
  • the handles 15 are serrated for ihcilitating their manipulation.
  • the interstices of the serrations are filled in at the bottom with colored matter corresponding to the color of the leads in the carriers.
  • the magazine 24 is slightly modified as compared with that illustrated in Figs. 1 and 2.
  • the barrel 43 is dispensed with and the sleeve 22 isv secured to the magazine by a rib 46.
  • the block 36 is pushed back with one finger and with the pencil still held in writing position, whereupon the carrier is immediately returned into its initial position by the automatic spring 32 without any effort on the part of the writer.
  • another carrier may be pushed into active position.
  • the pencil consists exclusively of parts which are simple and easily assembled, having regular geometrical sh apes and being particularly suitable for quantity production.
