To all whom t mayA concern.:

Be it known that I, ALBERT RoMAINE 'lAL-LMAN, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Combination Fountain Pen and Pencil, of which the following is a spcciiication f .y

The device `forming the subject matter of this applicationis a combination fountain,v pen and pencil. I am aware of the fact that, generally stated, an article comprising a barrel or holder, provided at one end with a pen and at the other end with a pencil, is old in the art. To such a broad combination, no clailnis laid. A combined article of thesort alluded to is, however, a useful structnre,.and this application proposes, as

one of its objects, thel provision of a device,- which, as an artlcle of manufacture may be used as a combined pen and pencil,.the construction being such that the length of the pen and pcm willnot be increased materially, notwithstanding the fact that it com'- bines the two instrumentalities above alluded to, and notwithstanding the factthat it includes a means for filling the pen, anda means for' feeding the lead in the pencil.

Another object of the invention istoimprove the constructionof-the pencil portion of the device, notably in so far'as Ythe leadfeeding mechanism is concerned.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the invention appertains. y f

A single material embodiment has 'been depicted in the drawings, as an illustration of one form which the invention may take, but within the scope of what is claimed, a exercising the skill of his calling,

may work changes in that form, without departing from the spirit of the invention.

Fig. 1 shows in longitudinal section, an article constructed in accordance with the invention, sundry parts remaining in elevation' Fig. 2 is a fragmental longitudinal section disclosing the sleeve portion of the leadfeedin means, and parts which co-operate therewith g 1923. Serialy No. 672,976.

l Fig. 3 is a transverse section taken on the l1ne-33 of Fig. `2;

taken on the part 3 being removable from the coupling. 70

The part 3 of the barrel has a reduced end is provided with, an internal thread 6, which may be pressed into the sleeve.

A tube 7 is rotatably mounted within the sleeve 5 and is secured at its outer end to a tip 8, havin a bore 9 which is co-axial with the bore o the tube 7 the tip having an annular fian'ge v10 surrounding the reduced end 30 of the barrel-part 3. a longitudinal slot 11, rshown best in Figures 6 and 3.

The lead-feeding means includes a plunger 12 disposed within the tube 7 and equipped at its forward end with a split resilient socket 14, adapted to hold the lead 15 which, in the operation of the device, is advanced through the bore 9 ofthe tip 8, .as occasion may demand. Intermediate its ends, the plunger 12 lis .supplied with a transverse sleeve 5 is located within the part 3 andf The tube 7 is provided with pro]ection 16 which bears upon the inner curved at its extremity to formja shoey 18,

facilitating the sliding movement of the plunger along the bore of the tube 7. In Fig. 2, the lunger 12 is shown in a retracted-position for two reasons: first, in order that the outline of the'plunger may appear clearly; and, secondly, in order that the functions ofl divers parts of the device may be' explained advantageously hereinace of the tube 7. The lunger 12 termi after. The plunger 12 and, more specifically, the resilient arm 17 thereof, 1s provided with a transversely extending fin 19 having notches or seats 20. The fin 19 slides in the slot 11 of the tube 7, the notches or seats 20 co-operating with the thread 6 of the sleeve 5. Since the sleeve 5 is fixed to the part 3 of the barrel, and serves as a mounting to permit the rotation of tube 7 with respect Ato the barrel, and since the plunger 12 is constrainedA to follow a right line movement in the tube 7, it isobvious Ythat when relative rotation between the tip 8 and the part 3 of the barrel is brought about, the

lunger 12 will be advanced, the lead 15 bein advanced in the' bore`9 of the tip 8. To hold the tube 7 against longitudinal movement with res ect to sleeve 5, the tube 7 is provided witli) a. flared inner end 7a which restricts the sleeve 5 between said flared end 7 and the tip 8 as shown in Figs. 2 and 6. With this explanation, the general operation of the' encil may be dismissed,

since the nature o such an operation is well own. f It remains, however, todiscuss the-merits of the plunger 12,and in this connection 1t is to be observed that Athe/resilient arm 17 of the plunger serves to hold the tin 19 in the slot 11 lof the tube 7, and to hold thev notches 20 of the fin in co-o erating relation to the thread 6 of the tu e 7, the projection 16 'co-acting `with they tube 7, to secure this result. The pro'ection 16, being formed by curving or ben ing the plunger 12, renders the forward end of the plunger comparatively rigid, the lead 15 being held always in such a position that it will enter the bore 9 of the tip 8, notwithstanding the fact that the arm 17 of the plunger is resilient.

The numeral 21 marks a tip, carrying a en oint 22, the tip being seated removably y t reading or otherwise,

the barrel l. The tip is a cle, for which no'novelty is claimed, and any kind of a tip, as a matter of fact, may be used. The pen point 22 is housed beneath a commercial arti- Acap 23, mounted ,detachably on the part 2 of the barrel 1. Any desired portion of the barrel may be provided with the usual pocket-clip 24.

The numeral 25 denotes a tubular plunger which is slidable in the parts 2 and 3 of the barrel and is supported immediately for sliding movement in the coupling 4, the couplin therefore, exercising. a two-fold oiiice. head 26 is attached in any desired Way to the inner 'end ofthe plunger 25, and fits closely but slidably in the part 2 of the barrel 1. Thehead may be held in place by a stud 27 on the plunger, and a washer 28 on the stud. c

The art-8 of the barrel-may be detached from tli)'e part 2-the'lead feeding mechanism in the part 2 otl Withdrawn and by the 'plunger 2n, oi ink may be through `the tip 21, the elements and 26 Y acting as a piston.

Especial attention is directed to the fact that when the plunger 25 is retracted, as a'`oresaid-,y and when the parts 2 and 3 of the barrel are again assembled, thesleeve 5 is received within the plunger. As a consequence the article embodies. in a combined pen and pencil, longitudinally movable lead- Jfeeding and pen-charging means, telescoped with respect to each other, the length of the article being cut down accordingly.

If the notches 2O in the plunger 12 do not happen to be engaged witlrthe thread 6 of the sleeve 5 when the plunger 25 is slid about the sleeve 5, then, as indicated in Fig. 2, the plungerA 25 will flex the end 17 of the plunger 12 sulicieutly to bring the notches into the position shown in Fig. 2, and the friction between the plunger 25 and the part 18 of the plunger l2 will advanceY the plunger 12 until the notches 20 catch the thread 6.

Having thus described the invention, what is claimed is:

. 1. In a combined pen and pencil, a barrel, longitudinally movable lead-feeding means in the barrel, and longitudinally movable pen-charging means in the barrel, the leadfeeding means and the pen charging means being telescoped within the barrel with respect to each other, to minimize the length of the article.

2. An article of manufacture for use in the makingot a combined pen and pencil having a minimum length, comprising barrel members; means for connecting said members detachably; a piston co-operating with one barrel member and including a tubular plunger `slidable in both barrel members; undylead-feeding mechanism embodying a sleeve whereon the plunger is telescoped, the sleeve being secured to the other barrel member. I

3. An articleof manufacture for use in the making of a combined pen vand pencil having a minimum length, 'comprising barrel members; a combined guide and couplin fixed to one barrel member land received removably in the other barrel member; a

ing threaded plunger comprising a resilient rarm co-operating with the .tube to hold said part of the plunger i-n threaded engagement with the sleeve; a second barrel member; and means for connecting the barrel members detachably, the second barrel member carrying a part c'o-operating with the resilient arm of the plunger, to bring said part of the plunger into threaded connection with the sleeve, when the plunger is in retracted position. n

5. In a combined pen and pencil, a barrel, lead feeding means in the barrel, pen chargmeans and said pe-n charging means overlapping each other within the barrel so as toclmimmize the length of the combined arti e.

connection with the sleeve, the

mg means in the barrel, said lead feeding as to minimize the length ofthe combined article. v

In testimony whereof, I `have hereto affixed my signature.

ALBERT ROMAINE TAILMAN.
