PENCIL.
SPECIFICATION forming part of Letters Patent No. 612,431, dated October 18,1898. Application fled January 21, 1897. Serial No. 620,127. (No model.)
To LZZ whom it may concern:
Beit known that I, FREDERICK W. MUssoN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pencils, of which the following is a specification.
My invention relates to pencils, and has for its object to provide a new and improved pencil, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure l is a view of a pencil embodying my invention. Fig. 2 is a view of the pencil with the parts separated, so as to more clearly show the construction. Fig. 3 is an enlarged section through the pencil. Fig. 4 is a section on line 4t 4, Fig. 3. Fig. 5 is a section on line 5 5, Fig. 3. Fig. 6 is a section through the pencil with parts omitted,showing a modified construction. Fig. 7 is a section on line 7 7, Fig. 6. Fig. 8 is a view of the leadused in the pencil, the lead being screw'threaded throughout its length.
Like letters refer to like the several figures.
The body A of the pencil is hollow and may be made of wood or other material, preferably. A tip B is removably connected with the body A, preferably by means of screwthreads. A lead O is' contained within the hollow of the pencil and is provided with two grooves C'. This lead passes through the sleeve or nut D and is adapted when in use' to project beyond the tip B. VAs illustrated in Fig. 3, the sleeve or nut D is provided with interior sore w-threads, and the lead is of such parts throughout size that said nut will form screw-threads tion projecting Vpartly through the hole B2, as
shown, so that it may be within reach and easily manipulated. This nut or sleeve is not connected with the tip, except as it is held inY place when the parts are in position. When the tip is loosened from the body of the pencil7 it can be moved and leave the parts in the position shown in Fig. 2, the nut or sleeve D being separate therefrom. The projections B B', which hold the lead from rotation, are preferably placed in the tip of the pencil. I have shown in Figs. 5,1 and 4 a construction wherein the body A of the pencil is provided with the projecting pieces or ribs A', which enter the grooves in the lead, and thereby prevent its rotation. It is of course evident that these holding devices may be placed at any part of the pencil. The pencil is also provided with an outer end E, which may be of rubber or of other material, if desired.
In Fig. G I have shown aconstruotion wherein the tip B is provided with screw-threads which form screw-threads on the lead, and thereby feed it backward and forward when said lead is rotated. The sleeve or nut D is provided with the projections D, which cnter the ,grooves O in the lead, so that the lead will be rotated bya rotation of the sleeve or nut.
In Fig. 8 I have shown a lead which is screw-threaded substantially throughout its length before being placed in the pencil. This construction may of course be used with either of the pencilsherein shown or with any othersuitable pencil. This lead is preferably circular in cross-section and may be made by forcing the lead through suitable dies provided with projections which form the grooves O. The leads after being made may be screw-threaded in any suitable manner, as by means of the process and dies set forth in my patent application filed August 10, 1896, Serial No. 602,273. c 4
It will be seen that I have here'a circular lead which can be held from rotation or which can be gripped so as to be rotated,the lead having all the advantages that are possessed by the ordinary circularplead.
The use and operation of my invention are as follows: When the device shown in Fig. 3 is used and it is desired to move the lead backward or forward, the sleeve or nut D is rotated, said nut being easily engaged by the thumb and finger on account of its projecting IOO through the hole B2, as shown in Fig. 2. The guides in the tip or other part of the pencil prevent the lead from rotating, but allow it to move longitudinally. The nut or sleeve is coniined between the tip and the body A of the pencil when the tip is in position, so that its rotation produces a longitudinal movement of the lead. The same result is obtained when the sleeve or nut shown in Fig. 6 is rotated. lIn this case the feeding device is in the tip of the pencil, the sleeve or nut simply engaging the lead by means of the projection thereon, so as to insure a rotation of such lead When the sleeve or nut is rotated.
I have here a construction which can be made at a very little cost and which is simple and practical.
I claiml. In a movable-lead pencil the combination of a case with a movable lead, a t-humbpiece adapted When rotated, to reciprocate said lead, and a tip, said tip provided With a hole in the end toward the case, the crosssection of said hole greater than the crosssection of the thumb-piece, such hole being therefore large enough to receive said thumbpiece, said tip also provided With means for attaching it to the case, there being openings in the sides of the tip through which the thu nib-piece can be reached to be operated,
and a hole in the outer end through Which the lead projects.
2. In a movable-lead pencil, the combination of a case with a movable lead, a thumbpiece adapted, When rotated, to reciprocate said lead, and a tip, said tip provided with a hole in the end toward the case large enough to receive the thumb-piece, and With means for attaching to the case, there being openings in the sides of the tip through Which the thumb-pice can be reached to be operated, and a hole in the outer end through Which the lead projects, said lead adapted to be screw-threaded and the thumb-piece provided with an internal screw to receive such thread.
3. A lead for lead-pencils, consisting of a long, substantially cylindrical body,said body provided With one or more grooves which extend substantially along its entire length, substantially as described.
4. A pencil comprising a lead, consisting of a body substantially circular in cross-section, and provided with one or more grooves which extend substantially along its entire length, a casing in which said lead is received, said casing provided With a projection engaging the groove in said lead.
