PENCIL.

Application filed June 13, 1922.

M declai e the following to be a full, clear, concise and exact description thereof 5111110161113 to enable anyone skilled in the art to which it appertains to make and use the same reference being bad to the accompanying drawings in which like reference characters refer to like parts throughout the specification.

The objectof the invention is to provide a pencil that will carry a plurality of leads to be fed to the working point of the pencil from time to time as the old ones become worn away and used up. Furthermore, the pencil is designed in such. manner that the replacement can be effected without taking apart any portion of the pencil but by the mere turning of certain parts thereof.

The object will be understood by referring to the drawings in which Fig. 1 is a central vertical section of the pencil, parts being enlarged;

Fig. 2 is a detail view, showing a perspective of a tube and immediate parts e1nployed;

Fig, 3 is a detail perspective view of a barrel used;

Fig. 4 is a detail perspective view of the lower part of the pencil that is used;

Fig. 5 is a detail perspective view of a metallic cap or ferrule employed;

Fig. 6 is a detail perspective view of another cap or ferrule employed;

Fig. 7 is a detail perspective view of a tube used;

Fig. 8 is a detail perspective View of a device for holding the pencil to a coat pocket, which-device is used in connection with the said pencil.

Referring more particularly to the draw ings, the pencil embodies a lower member 1 that is conical is shape at 2, An elongated annular aperture 3 is formed in the center part thereof and is just large enough to allow for the passage of a single lead 4 that fits rather snugly therein, whereby the lead' 4 will not drop thereout.

The upper part of member 1 has an enlarged annular chamber 5 that is connected to aperture 3. A conical surface 6 is formed therein to direct the approach of leads 4 towards aperture 3, as said leads 4 drop into chamber 5 through aperture 9 from their respective positions in revolvable barrel 7.

A metallic rotary cap or ferrule 10 is disposed over the upper reduced end 11 of member 1 in a rather tight fitting manner.

Serial No. 567,904.

invention relates to a pencil and I A notch 12 is formed in the side of cap 10 to hold said cap 10 from turning easily, Said cap 10 is equipped with an aperture at 13 for the projection therethrough of a, hollow tube 14. Cap 10 also has a peripheral recess 15 adapted to" aline with the several recesses 16 formed in barrel 7., as said recesses 16 are brought respectively opposite thereto.

a Barrel 7 has as above stated, a plurality of recesses 16 for the storage of leads 4. It has also a central recess 20 for the reception of a metallic tube 14 that forms a pivot upon which said barrel 7 turns, whereby to bring the successive recesses 16 opposite recess 15 in cap 10.

Hollow tube 14 has an internal spiral groove 23 adapted to receive the upper bent end 24 of a rod 25. Rod 25 is disposed within a hollow tube 26 that is contained within the hollow tube 14. Tube-26 is provided with an elongated slot 27 throughout part of its length for the passage therealong of the bent end 24 of rod 25, whereby said rod 25 will be able to move in a limited vertical plane as determined by the rotation of tube 26.

The upper end of tube 26 is fastened to turn with the rotary handle 30 that has a serrated periphery and is adapted to turn independently of member 33 that is located just below. Member 33 has a central annular recess, whereby to allowfor the projection of tube 26therethrough. The lower reduced part 35 of member 33 fits within the metallic cap or ferrule 36 which is mounted likewise upon tube 14. Cap 36 is equipped with a notch 37 to prevent it from turning freely. It has also an open recess 38 adapted to aline with a recess 40 formed in member 33, whereby to allow for the insertion of leads 4 preparatory to refilling barrel 7.

The operation of the pencil is effected by revolving cap 36 to bring its recess 38 opposite recess 40 if not already opposite. Likewise barrel 7 is revolved to bring a recess 16 in alignment with recess 38 and with 40. A lead 4 is dropped then into recess 1.6 of barrel 7 through the openings formed by recesses 38 and 40. It may be necessary to tip the leads 4 slightly or to raise handle 30 when inserting said leads 4 to bring the next recess 16 therein opposite recess 38 and 40. Barrel 7 is revolved thus until all the re cesses 16 are filled with leads 4.

Cap 10 is turned now to bring aperture 15 opposite one of the recesses 16, as alined with recesses 38 and 40, whereby to allow a lead a to drop down into chamber 5. From thence the lead 4 will be guided by the conical surface 6 into aperture 8. Rod '25 will be lowered now by turning handle 30, whereby to push lead 4 down in aperture 3, so that the lower end thereof will project beyond member 1 for writing purposes.

As leads l are used up, others can be directed into aperture 3 to replace the ones so used by turning barrel 7 and cap 10 to aline an aperture 16 oi barrel 7 with recess 15 of cap 10.

Having thus described my invention what I claim as new and desire to secure by Let-- ters Patent is:

1. In a pencil, a barrel for containing a plurality of leads, a revolvable member for disposing said leads in operating position, a cap permitting said leads to be fed from the barrel to said member, said member hav ing a conical surface, whereby to direct said leads to operating position, and a rod located within said barrel for pushing said leads towards said operative position.

'2. In a pencil, a barrel for containing a plurality of leads, a revolvable member for disposing said leads in operating position, a cap disposed between said barrels and member, whereby to permit the leads to replace worn out leads, said member having a conical surface, whereby to direct said leads to operative position, and ,a rod located within said barrel for pushing said leads towards said operative position.

3. In a pencil, a barrel for containing a plurality of leads, a revolvable member having an aperture for disposing said leads in operative position, a rotary cap having an aperture, whereby to permit the leads to move from said barrel to operative position,

said member having a conical surface, whereby to direct said leads to operative position, and a rod located within said barrel for pushing said leads towards said operative position.

4:. In a pencil, a barrel for containing a plurality of leads, a revolvable member for dis posing said leads in operative position, a rotary cap disposed between said barrel and member, a conical surface within said member, whereby to direct said leads to operative position, and a rod located within said has:- rel for pushing said leads towards said operative position.

5. In a pencil, a rotary barrel containing a plurality of leads, a revolvable member for disposing said leads in operative position, a rotary cap disposed between said barrel and member, whereby to permit said leads to move into operative position, a conical surface within said member, whereby to direct said leads to operative position, and a rod located within said rotary barrel for pushing said leads towards said operative position.

3. In a pencil, a rotary barrel containing a plurality of leads, a rotary cap located above said barrel and having a recess for the admission oi leads to said barrel, a member located below said barrel for holding the leads in operative position, a conical surface within said member, whereby to direct said leads to operative position, a second ro tary cap having a notch and located below the barrel, whereby to admit leads to said member, a rod for pushing said leads into operative position, and a handle for actuating said rod.

In testimony whereof I have ai'iixed my signature.
