includes means tor releasingthe air in the barrel tor hrealring' the suction therein caused during the filling ot the pen upon the upstrolre movement ot the plunger.','
ll turther object is to provide apen ot the above mentioned character that is simple in construction, inexpensive, strong and durable and turther tvell adapted to the purposes tor'vvhieh it is designed. i
U ther objects and advantages Will become apparent during the course ot the tollowlng description;
tn the accompanying drawing, torming a part ot this specification, and in which lilre numerals indicate lilre parts throughout the same: I
ltlignre t is a longitudinal sectional view through the tountain pen embodying my invention 1 a l i "ure 9; is a transverse section talren upon the line ot Figure l-loolring upwardly, {m d v v l igure it .is'a similar section talren appronim'ately on the line 3-4 ot the same figure loolring dovvnvvardly.
tn the dravving vvherein tor thepurpose ot illustration is shovvn the preterre'dembodirnent at my invention, the numeral 1 desighates the cylindrical barrel that is open at its respective ends, i
it. substantially cup-shaped head 2 is threaded at its upper end Within the lovver end ot the barrel and this head is termed in its closed lotver end vvith the central inh teed passage 3 tor supplying inlr trom the barrel to the nib t in the usual manner,
"l helorver closed end ot the cup-shaped head ft turthermore tormed with a through ti and a chech valve 6 is arranged in the upper end ot the passage as clearly ltl shovvn in l igure l. This checlt valve nor-- mally is disposed in a closed position to prevent the escape ct the inlr through the passage 5 but is adapted to be opened under the suction created in the barrel by the sliding plunger during the filling operation ot the fountain pen in the manner to be presently described.
This check valve is limited in its upward movement by reason of a pin and slot connection as is also clearly indicated in lEigare l. t p r g The upper end ot the bore ot theharrell is reduced vvherehyto term the shoulder it l1 tor a purpose to he presently described.
The plunger or piston rod 8 is externally threaded adjacent the piston 9 tor cooperation With the internally threaded portion 18 ot the reduced portion ot the bore of the barrel tor maintaining the'piston in its upperniost-position within" the barrel against the shoulder 7.
'.l"he upper end ot the tubular plunger or piston rod 8 is internally threaded tor reeeiving the externally threaded sleeve 12 termed on the bottom ot thesolid head 18 that'provides a closure tor the open upper end ot the tubular piston rod. Depending trom the bottom of the central portion ct this solid head 13 and extending throughout the length ot the tubular piston rod is the elongated pin it, the lower endthereot heing slightly rounded ton cooperation with the seat 'Illtorme d at the upper end ot the air escape opening 10. v
' The upper end portion ot the tubular piston or'plunger rod 8 is termed in its side With an air escape opening'lh and the sleeve l2 istormed with aslrnilar opening 16 tor tor a purposeto he presently described andthc lovver end portion ot the reduced upper end ot the bore is threadedas suggested cooperation therewith. The usual cap that isremovably secured'over the point ot the fountain pen is shown at fl? and the samels barrel l.
detachahly secured on the lower endot thelltl .in Figure 1, it will be observed that the 'the piston 9 will be disposed in the upper portion'of the barrel against the shoulder 7. Prior to the filling of the pen, the cap vis removed and the piston rod disconnected from the threaded portion 18 of the barrel after which said piston rod is\forced downwardly in the barrel to position the piston 9 against the bottom of the cup shaped head 2.
The nib of thje pen is then immersed into a bottle of ink or inkwell so that the head 2 is submerged. The piston rod 8 is then moved upwardly through the upper open end of the barrel causing the upward movement of the piston 9 in said barrel and this movement will create-a; suction in the barrel to raisethe valve 6 out of its operative position and simultaneously draw in a. quantity of ink into the barrel. i
, After the piston has reached the endof its uppermost movement so that said piston strikes theshoulder, the piston rod is rotated in the reverse direction to secure said piston rod against vertical movement and to further-maintain the piston against the shoulder.
The solid head' 13 is then actuated to rotate the sleeve whereby .to bring the opening 16 into registration with the opening 15 and simultaneously the lower end of the elongated pin 14 will be moved out of engagement with the seat 11 and the vacuum created in the barrel will be released. When the vacuum is broken, the head 13 is again actuated to move the openings 15 and 16 out of registration with each other and at the same time, the lower rounded end of the pm 14 will rest in the seat ll and thus prevent the admittanceof air under pressure to the barrel.
The ink will flow from the barrel to the nib 4through the passage 3 during the use of the pen when writing in the usual man ner. 1 s
It will thus be seen from the foregoing description, that I have provided-a'fountai'n pen that will obviate the necessity of having. to employ the-conventional rubber sack or bagand thus thedifeof the pen is prolonged and also a maximum amount of ink mag be carried by the barrel.
F urt ermore my improved fountain pen. is of such construction asto permit the same to be readily andeasily operated for refilling the same whenever necessary and the pen will not leak.
While I have shown the preferred embodiment of my invention, it is to be ninlcrstood that various changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention and the scope of the appended claims.
Having thus described my invention, what I claim as new is:
1. In a fountain pen, a barrel, a conventional nib associated with the lower end 01 the barrel for receiving the ink therefrom,
the lower. end of the barrelbeing formed with an inlet, a check valve .i'or said inlet opened under suction created in the barrel, a piston rod operable through the upper end of the barrel, a piston carried by the lower end of the piston rod, said piston adapted to create a suction in the barrel for filling the same upon the upstroke of the piston rod, means for limiting the upward movement of the piston in the barrel, additional means for securing the piston in its raised position, said last mentioned means comprising external threads formed on the lower end portion of the piston rod above the piston, the upper end portion of the bore of the barrel being threaded for. cooperation with the threads on the piston rod.
2. In a fountain pen, a barrel, a conventional nib associated with the lower end of the barrel for receiving the ink therefrom, the lower end of the barrel' being formed with an ink inlet passage, a check valve for said passage opened under suction created the head and extending downwardly in the tubular piston rod, the lower end of said pin adapted to be positioned over the upper end I of the opening in the piston when said head is in its lowermost position, said head and the tubular piston rod being formed with air openings adapted to register with each other when the head is in its raised position for the purpose described.
In testimony whereof I ailix my signature.
