J. M. MILLER COMBINED PEN AND PENCIL Sept. 18 9 H923.
Filed March 23, 1922 Win/5536s Patented Sept. 18, 1923.
JOHN MEREDITH .MILLEIL 0F NEW YORK, N. Y.
COMBINED PEN AND PENCIL.
Application led March 23, 1922. Serial No. 546,110.
To aZZ whom 'it may concern.'
Be it known that I, JOHN MEREDITH .M1LLER, a citizen of the United Stat/es, and
a resident of 503 W. 140th Sit., New York city, in the county of New York and State of New York, have invented a new and useful Improvement in Combined Pens and Pencils, of which the following is a speciication.
The invention relates to combination fountain pen and mechanical pencil.
An object ofthe invention isto improve the construction, and as a result thereof the convenience and operation, of combination pens and pencils, and a further objec't is to provide a combination self filling pen of the piston ty-pe and a mechanical pencil in which the pencil forms the piston for the pen, and in which the pencil may be locked against movement with relation to lthe pen after the pen has been filled.
The invention is illustrated in the accompanying drawings, of .which Fig. 1 is a central longitudinal sectional view of the combined pen and pencil; Fig. 2 a side view of the pencilwhen removed from the pen; and Fig. 3 a transverse sectional view taken on the line III-III, Fig. 1.
Referring to the drawings, a tubular reservoir 1, preferably of cylindrical form, cons'titutes the container or writing-Huid reservoir for a fountain pen 2 which is suitably -attached to its outer end. The fountain pen maybe protected by a suitable cap 3, which is preferably provided extei'-, nally with a roughened file-like section 4 for sharpening the lead of the pencil. The pen is of the self-filling, piston type, the piston for which is at the end of a piston rod in the form of a tube 5, which isalso the casing of a. mechanical pencil. Means are provided for locking the tube and reservoir against relative movements when the piston is moved to the inner end of the tubular reservoir so that there may not be an accidental reverse movement of the pencil within the pen reservoir to forcibly ejec't the writing-Huid.
The piston at the end of tube 5 may take the form of a head 6, surrounded by a suitable packing sleeve 7, which may be formed of cork. To lock the piston in its position adj acent to the inner end of reservoir 1, that is to say in the position indicated in Fig. 1, tube 5 is preferably provided with an external thread 8 adapted to be received by an internally formed thread on an inwardly enlarged portion 9 at the inner end of the reservoir.4 When thethreads of the tube and reservoir engage each other the pen and pencil are locked against relative axial movements and each lengthens the grip for the other. Leakage of writing-Huid between the piston and the inner en d of the reservoir may be prevented by a packing ring 10 arranged between a flange 11, with which piston 6 is provided, and an inwardly extending Harige formed b-y the enlargement 9 of the reservoir.
Various types of mechanical pencils may be used to form the piston and piston rod for the pen. In the pencil shown herein casing 5 is interiorly threaded and has arranged in it a tube 12 provided with longitudinal slots through which there project the sides of a follower 13. The inner end of tube 12 may be provided with an annular groove 20 adapted to be engaged by a split-expandable ring 21 arranged in a recess 22 formed in.the piston head 6. In this way the end of tube 12 may be rotatably mounted in casing'. Follower 13 is provided with serrations cooperating with the threads formed on the interior of tube 5 so that when *this tube is rotated in a right hand direction the follower will move toward the outer end of the pencil.
At the outer end of the pencil a tip 14 is attached to tube 12 by a left hand thread 15, the tip being provided with an opening to receive a lead 164. l
To retard the outward movement of a lead, a packing of elastic material is preferablyl arranged between the lead and the inner wall of the opening, in which the lead is arranged. This packing may, and preferably does, take the form of an annularl body 17 of cork or rubber, which is sufficiently elastic or compressible to permit the movement of a lead through it, but which frictionally resists such movement of a lead suiiiciently to 'prevent the lead from dropping out of a pencil.
A storage chamber for eXtra leads for the pencil is'provided in the form of a sleeve 18 surrounding the pencil casing 5. This sleeve is provided with lead receiving chambers 19 adapted to be closed by the end of reservoir 1 when the sleeve is in its normal position upon casing 5, the casing being of Smaller external diameter than reservoir 1. To hold sleeve 18 upon tube 5, such' filling of reservoir l1, writing-fluid being drawn in by the suction action of piston 6. Tube 5 and reservoir 1 may then be rotated so that they become attached to each other through the threads 8 on tube 5, and there# after storage reservoir 18 may be placed upon tube In causing follower l13 to move towards.
the point of the pencil to eject the lead, the left hand threaded connection 15 between tip 14 and casing 5 becomes somewhat tightened so that the turning of casin A 5 to move follower 13 inwardlywill not oosen the threaded connectionl. However, when the follower reaches its extreme inner position, further turning of tip 14 will detach it from casing 5 so that a new lead may be inserted from the inner end of tip 14. Tube 12 may be removed from casing 5 by pulling the tube outwardly with sufficient force to spread split ring 21 and thereby disengage groove 20 of tube 12 from this ring. Such removal of tube 12 may be desirable to fix the pencil in case it does not function properly.
According to the provisions of a patent statute, I have described the principle and operation of my invention together with the preferred embodiment thereof. 'Howeven I desire to 'have it understood that, within the scope of the appended claims, my invention may be practiced by other forms of construction than that particularly shown and described.
I claim: y
1. The combination of a tubular reservoir having a fountain pen at its outer end, a tube provided with a head forming a piston movable through said reservoir to fill the reservoir with writing fluid, said tube forming the casing of a mechanical pencil, and means for locking said tube and reservoir against relative movements when the piston end of the tube is adjacent to the inner end of the reservoir.
2. The combination of a tubular reservoir having a fountain pen at its outer end, a tube provided with a head forming a piston movable through said reservoir to fill the reservoir with Writing Huid, said tube forming the casing of a mechanical pencil, the inner end of said reservoir being interiorly threaded to receive external threads formed on said tube adjacent to the piston, whereby' the tube and reservoir may be locked against relative movements when said piston is adjacent to the inner end of the reservoir.
3. The combination of a tubular reservoir having a fountain pen at its outer endand having an inwardly Vextending flange Vand interior threads at its inner end, a tube provided with a head forming a piston movable through said reservoir to fill the reservoir `with writing fluid, said tube forming the casing of a mechanical pencil and being provided with an exterior thread adjacent to said piston adapted to engage said interior threads on the reservoir, and a packing ring arranged lbetween said flange and said piston.
4. The combination of a tubular reservoir.lv having a fountain pen at its outer end, a tube 5. The combination of a tubular reservoirl having a fountain pen at its outer end, and a mechanical pencil. including 'a threadably advancing lead expeller, reciprocable insaid reservoir and provided at its end with a piston whereby said pencil forms the piston and piston rod of a piston-type Self-filling fountain pen.
6. The combination of a tubular ink reservoir having a fountain pen at its outer end, and a mechanical pencil including a rotatable tip and threadably advancing lead expeller operatively connected to the tip, said pencil being movable in said vreservoir and -being provided with means for filling the reservoir by relative movement between reservoir and encil.
.7. Thecombination of a tubular reservoir having a fountain pen at its outer end, a tube of smaller outer diameter than that of said reservoir secured to the inner end'of said reservoir and forming an extension thereof for a longer grip, said tube being the casing of a mechanical pencil and being provided'with'an open ended chamber to receive extra leads, the open end of said chamber being normally closed by the inner end of said reservoir.
In testimon whereof, I sign my name.
