MORRIS W. MOORE, OF EVERETT, MASSACHUSETTS, ASSIGNOR '10 SAMUEL WARD COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
FOUNTAIN-PEN.
Specification of Letters Patent.
Patented Nov. 2l, 196W.
Application filed December 14, 1908. Serial No. 467,327.
To all whom it may concern.'
Be it known that I MORRIS W. Mooier, a citizen of the United States, residing at Everett, county of Middlesex, Commontain new and useful Improvements in Fountain-Pens, of which the following is a specification.
This invention relates to fountain pens and particularly to subinerging fountain pens iii which the pen, when not in use, is kept immersed in the ink for the prevention of drying and the insurance of in'iinediate' lavailability of writing fluid at the point when put into use.
'i`wo difficulties generally encountered in this type of pen have been, rst the difficulty of securing a positive and rapid subiuersion and einer-sion of the pen without violent displacement of the ink which causes syringic action or splash oi' spatter, and second, its structural difficulty of providing working parts which would not be liable to leakage at joints, and particularly at packing. To the end, therefore, of overcoming these various diiiiculties and providing a general pen structure which will. be cheap and efficient I have produced a subinerging peu in which the movement of the pen assists-,iii a quiet transfer of ink so that the suhinersion and einersion occur by a positive transfer of the ink through the action of the parts rather than b v a dislrilacenient or surge of the fluid.
ln my pen also l provide for the mounting ot' the motive parts in a bore or chamber entirely closed at its rear end, thus avoiding the liability of rear end leagage from defective or worn packings and, by having a uniform bore wholly open at the forward end I make possible an internal engagement from the forward or muzzle end.
'Ihese various features and details of structure I will more fully set forth in the specification which follows by a description of a pen embodying my invention which, for the purposes of illustration, I have shown iii the accompanying drawingia In this drawing and throughout the specication like reference numerals are employed to indicate corresponding parts and in the drawings Figure l is a longitudinal section of the pen with parts in writing position, Fig. 2 is a similar section with parts engaged ready for closing, Fig. 3 is a sectional view with the pen submerged and closed, Fig. i is a rear end view of the sup- I port cut olt' at the indicated line llt-at, Fig. 3, g Fig. 511.-' a plan lview of the threaded bearing wealth of Massachusetts, have invented cerfor the pen har, and Fig. (j is a view of the operating device which is contained in the cap. l A
l is a pen barrel having a. uniform tubular bore .2 open at the forward end and closed at the opposite end. ll/lithin the bore 2 is an internally threaded bearing 3 pierced at 231 for the free passage of ink. In the hearing 3 works a bar Ll externally threaded at 5 and longitudinally slotted at 6.
T is a stop formed on the bar 4to preferit-u the movement of the pen too far in and 8 is a pin through the inner end to prevent the pen bar from working out of the bearing 3. At the `forward end il of the bar 4iis formed the pen seat and feed duct and near the end 41 and preferably at the base of the pen 9 is a piston l5 of the size of the bore 2 but freely working therein.
l0 are spiral ducts cut on the edge of the saine pitch as the threading 5 of thebar 4. The forward end of the piston l5 is extended with a. slight taper lli to furnish frictional A engagement.
piston l5 which have approximately the- S0 of the barrel l for the recept-ion of the cap 95 when the pen is being used.
The operation of the pen is as follows When it is desired to close the pen from the writing position shown in Fig. l the ea 1l is removed from the rear end 19 of the airel 1 and slipped on over the pen end of the barrel. The beveled face 14 of the friction ring I4: thereupon is brought against the beveled contact surface 16 of the piston l5 and upon the turning of the cap 11 the pen and piston will be drawn into the operation of the threaded bar 5 in its bearing 3. The threading of the cap 11 and theV barrel i is sdisposed as to permit the cap to travel down the barrel a sufficient distance before the screw threads 17, 18 engage each other, to back the pen Well Within the chamber et. In this inward travel of the piston 15 during which it rotates, the ducts 10 pass the ink forward to the front side of the piston, being practically an Archimedean screw. ln this manner the en is submerged iithout a sudden or distur ing displacement of ink in the chamber.
To lill the pen the cap is Withdrawn by a direct pull as soon as the threads l?, 18 are disengaged. The ink may then be poured or dropped into the open end of the pen; The entire chamber 2 may be illed in this way as the ink readily passes the ducts l0 in en teringand Works back through the passages 4 in the bearing 3. The pen may-then be sealed again by screwing on the cap or may be put into operative position by Working out vthe pen by a reversed screwing of the cap.
VVhen-the pen is out in Writing oosition the barrel may be safely inverted as the at mospheric pressure will prevent leakage through the ducts 10.
I am aware that in various pen and pencil,
and even fountain pen structures a writing' point has been moved to a position Within the holder and that a cap has been used to operate parts to move such pen, but l am not aware that anyone has produced a submerging fountain pen'in which the pen is turned back into the ink of the reservoir by an engagement from the pen end of the barrel.
Wha-t I therefore claim and desire to secure by Letters Patent is l. A submerging fountain pen ,comprising a barrel having a tubular bore uniform throughout, a cylindrical piston fitting said bore and movable therein, said piston having a longitudinal passage for the transfer of ink, a rearwardly extending threaded bar on said piston,a threaded bearing for said bar in sad'barrel, a cap and means in said eaplfor producing a submerging or emerginn'rotation of said bar;
A submerging fountain pen comprising -a barrel having` a tubular bore uniform throughout, a cylindrical piston fitting said 1ooreand movable therein, said piston having a-aassage therethrough for the transfer of 'an annular engaging surface about the l l l sedes? non end of said piston, a rearwardly este d ing threaded har on said piston, a thre hearing for said bar in said barrel', a and an annular ring` in said cap for contar ing` with said engaging surface 'to rotate said pen ban 2. submers'ing fountain pen compris a barrel having' a tubular bore uniform througrlrfnit, a cylindrical piston fitting` aid here and mor-able therein, said piston ha ying` a longitudinal passage for the transfer of ink, a rearwardly extending threaded bar on' said piston, a threaded bearing for said i in said barrel, a can and means in said een for engaging said piston to canse thepen to suhinersre or emerge.

5. A subinerging fountain pen comprising; a harrel open at one end only, a cap, a pen support having a longitudinal ink duet and i a screw thread, a thread bearing' for enga ing' said thread for the longitudinal adju ment of said support in said barrel, an eater nal annular friction surface on said pen aan l port, and a ring in said cap for frictions-ily engaging said. annular surface to operate said screw adjustment.l
G. A submerging fountain pen comprising` a barrel open at one end only, a cap, pen support having a longitudinal ink duct and a. screw thread, a tlireaded bearingl for 'engaging' said thread for the longitudinal adjustment of said support in said barrel, an externallybeveled annular friction surface on said pen support, and a-beveled ring in said cap for frictionally engaging said annular surface to operate said scren7 adjustmentn ln testimony whereof, l aliiX my signature in presence of two Witnesses. l
