v'said well being providedwitha cover Mil and j the 'reservoirmember B05 as shown clearly in Flgj'r"A f. n y I Formed as a part of the reservoir member it is a cylinder'if constituting Valpen receivingl member, said cylinderbeingprovided with. a central bore E39 in which is mounteda cylindrical plunger tube l32 the uplr .end portion of which is provided with a pen' receiving opening 13%. Connected with the tube 32 at its upper end vportion inany suitable' or desired manner is` a pen gripping member 36 formed of elastic mae terial, substantially frusto conical in'form and surrounding the yuppervend.'portion'oi the tube d l n n `[32 an'dfprovided with* a Vsecuring yflange He ar- Inthe form of the invention showninigs.v
ranged on the upper end portion of 'themember Ai223 vand 'secured by'a .nut Miti, the latter being internally recessed to accommodate the pen gripfping member i352 The tube i32`is provided with an airl port M2' which, when the 'tube isk in its normal position as indicatediin Fig. 'l isabove the level of the ink in the well. The rscribed is preferably'arranged' within -a housing l-5i provided with a removable cover portionyl'il which;` when' removed, permits access to theink well iustdeff in the'well |638 through an "openingrv .ide formed inl the cover 'i HJ.' Obviously, theapp'aratus may be supplied with ink through opening M8.
andbeing somewhat below the valve 22 it is apparent lthat the pen when 'in' use,y may-held in any position jwithout ink passing into the tube 2E). o
Inthe form of the invention shown in `Fig.2,` as yinl: enters the barrel rAY under ypressure by op-1 L eration ofthe lling'apparatus hereinafter de.-
scribed, the air within thebarrel A o'fjthe pen is compressed which obviously will alsocompress the airintube i8 and, because diaphragm 52 is, normally in the position shown in Fig; 5,
being undeflected, the air inbore 55 and chamber Siiwill be compressed. Normally an air passage is established throughboreqS, ports 5d. and 58 and bore 50 to air chamber 39` and the diaphragm 52 is not delectedbecause thesame' air -pres-v ,o sure prevails on bothsidesofthe diaphragm `52. This, obviously, is the Acondition wheny the 'ink ylevel in'v the barreliA-is,below`the lower endof 'apoint in excess of theaction of the spring fifi,
the tube 4S. yCiornpressing the air as mentioned above will cause the'air, in chamber 39 to reach and valve i2 will lthenbe unseated to permit escapev of air from chamber 39 tothe atmospherev through port 46, following which ythe valve 42 will be re-seated on theend of bushing 35. VThis action will be repeateduntilfthe ink vcloses the lower end of tube i8 to form two independent and nonfcommunicating columns of air, one
within the barrel-A o-utside of tube 8 land the other within the tube d8. As inkoontinues to be forced into the barrel it Ywill also passv into the tube'li, rbut the level of the i-nkwill rise more quicklyin the bore 56 of tube t8 tha'nin thev `barrel outside of the tube for therea'son that thek air volume in chamber 33 andbores'j, 5t
' and 55 decreasesless fora definite rise of ink in bore 56 than does the air volume inthe barrel A for the same 'riseof link level. This is due to @the fact that the air voluz'neV in bore 55 is substantially less thanthe air volumein chamber 39.
In effect, asthe ink level rises, the air pressure" in barrel A increases` more than the air ypresvsure-in air chainberBQ'until the pressurev of the l lair against valve 42 andV withinv chamber 39 vreaches a point in, excess of the combined action `of the spring Maand the atmosphere whereupon y valve 42 will unseat to permitl venting of the air from chamber 39. V Such venting of the air, as just described causes a sudden drop ofk air pressurein chamber 39, and the resultant air pressure will be less than the pressure ofthe air with'- inthe barrel A outside lof tubeff which will ,'tion shown in Fig. 2 where port 54 is closed andv cause thev diaphragm 52 to deilect vto thel posisevering communication between bore 55,V and chamber 39. pressure vinto the barrel A after port 5ft has loeenclosedby diaphragm52 willcause ink to lrise in bore 55 and the barrel` A Auntil the pressure of, air l,above the ink in bore 56 increases to a pointwhere it balances'the pressure of theairl on the ink in barrel A. Increase in inl; level `within` the barrel and the bore 55 obviously in- Y creases the respective air'pressures in the bore 55 within bore 55 is less than that'in the barrel A the diaphragm 5,2 will remain in a deected posiandbarrel A but Abecausethe pressure of the air tion suchas shown in Fig.` 2.
When inflow of ink into theybarrel'stops'as determined by arvpressureswithin the barrel A l `and tube d3, a certain amount of inl:` will loe'forcec'i` eut'ozfethe barrel `dueto theexpansion of the air Vtrapped above .the ink the barrel and in the bore 55 until the pressure ofthe air in the pen balances .the loutside'f, atmospl'ieric pressure whichfwill occurl Continuedv entrance of ink under when theV ink inthe pen has; receded to a level somewhat lower than the end of tube ein It is ob- Viousthat the diaphragm 52 will Yagain assume the ,position illustrated in Eig; 5 as soon as the receding inkagain opens bore 56 whereby identical air pressurer ori'. oppositev sides A of ydiaphragm 52 are established.,` y* .y f j In the form ofA the invention shown in Figs. 3 and as ink is forced into `thebarrel'the airin the latter and in air chamber 89 is compressed in the samefratio because there is direct communication between the interior of the barrely and said air chamber through ducts Eik 115,32, 84 and S3;
o the diaphragm 7 5 :being retained in its normal and undeected'positionbecause the air pressure lon opposite sidesgthereof ris uniform. kWhen the vair pressure within chamber 89 is sufficient, the
valve 94 is unseated to permit ventingrofexcess air through port itil and this operation is re'- peated until the ink reaches the lower end of tube v iiiito close bore E8 to separate the kairin barrel A from-that in chamber 89; With the vbore 68 closed against passage of'lair therethrough it is yobvious that the pressure of the air Within the barrel QA will increase beyond thatin the chamber 89. Ink willbe forced upwardly within bore 68 'which will compressthe air thereabove to a point such as'to cause thel air pressure within chamber 39 to vunseat valve Se thereby causing a sudden drop in air pressure within such chamber 89 to a point below the pressure kof the air in barrel A and, the air in barrelA will actthrough thev openings lll against-,the 'diaphragm l5 lto close a duct 84.
l' With-duct 8d closed as just described, the pressure ofthe air onthe ink in barrel YA causes ink to rise in vbore 'thereby compressing the air thereabove until the pressure thereof balances the ball valve |34| closes port |39 against escape of air therethrough. The specific arrangement shown inFig. llafprovides three columns of air;V
one within the'barrel A, another indicated at lill around the tube |23, and a third, the bore |39 of the innertube |23 land these columns are l Vnormally at auniforrn pressure. This condition t prevails as long as communication exists between them and the'interior ofthe barrel at the lower end of tube "|23 bymeans of the port of opening I9 in thenozzle portion of 'tube' H5. As ink enters the barrel AA, the air. in these three-columns is compressed;A the air in column|4| passing through 'portsl |21. `When sufficient pressure hasY developed beneath the diaphragm |||the latter will be deected yto uncover port |33 to permit escape of air. through said port to the atmosphere through vent |37. As longas the ink level remains belowv the nozzleV ||'|,the'va1ve |31 will remain seated to close the upper end of bore 139.-). lWhen,r however, theink reaches the lower en diof the nozzle lilas shown by the ink vlevel indicated in dotted lines at |43, the lower end of v-thegnozzle is closedand air communication between the interior Vof the barrel.A-and the ventmember is severed. Increase rof ink in the Y rbarrel A to thelevel diagrammatically indicated bya broken` line' atv |45 .establishes three seri-.ed forst-orage inathbore maand rmiy heid in position by means of the lpen grip memberilrl.-
Downward pressure'` on" the barrel A of the'pen` will cause downward'movement of the plunger'-v |64 to the positionshown in Fig. -10 which places' `the ink in the deskset member under pressure whereby it is forced upwardly in thebarrel Al n throughthefeederbar F.- Downwardfmove-k ment oftheplunger |64 as described '.will cause theball valve |58 to close the passage |55 Wheree yby the ink in sump |60 is retained under pressure.
