AELPH MUEHLMATT, OF/ NEWPORT, KENTUCKY.
SELF-FILLING FOUNTAIN-PEN.
Application filed April 5, 1912.
Specification of Letters Patent.
Patented in ne 1 7 i913.
Serial No. 688,668.
Be it known that l, Anonru )'liiinnnvr'r, a citizenof thefl-.lnited States, and a resident of the city'of Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful improvements in Self-Filling .l"ountaiu-l)ens. otl which the following is a full` clear, and exact description, reference being had to the accompanying drawings, forming a part of Vthis specitication. My invention relates to fountain pens which till through the ink feeding` channel and especially to such pensas employ a rubber sac for an ink reservoir and till by deflating the rubbei` sac.
Ordinarily the employment. of this means of filling peus has been accompanied by the use of complicated devices for detlating the sac, which require several movements in their operation, and are an annoyance to the user, as well as troublesome to the manufacturer.
To simplify and render more ellicient. the deflating device is the special object of my invention, and this I accomplish by that certain novel construction and arraiigen'ient of parts to be hereinafter pointed out and specified, whereby I detiate the rubber sac by means of a long and narrow plate actuated by'turning a screw in the end of the barrel of the pen',
In the drawings, Figure 1 is a vertical section of the pen with the rubber reservoir in normal position. Fig. 2 is a similar section, With the reservoir detlated. Fig. 3 is a perspective view of one end of the inner tube. Fig, 4 is the operating screw and disk. Figs. 5 and G are views partly in sei-tion of modifications of that part shown in Fig. 4.
l is the barrel of the pen made of suitable material, such vulcanized rubber, into which is screwthreaded at one end a tapered portion 2, containing` the ink-feeding tube 3, and into which is inserted the pen point 4. The portion 2 is extended at the base toform an end 5 on which is slipped the long rubber sac 6.
Of a size to tit closely within the barrel l, is the tube 7, Fig. 3, with annular grooves 8, 8 about its circumference, and transverse these groovesfthe slots 9. A long narrow plate 10 is provided, with links 11, of equal The other end of each link is placed through the slots 9 and bent v over at 12 to engage ringsl 13 which are inserted in the grooves H and drawn through vthe bent ends 12. The one eudof the tube 7 is grooved at 14, 14, so that ridges are formed on its inner surface te engage notches 15. 15, in ay disk 16. 'lhis disk lo is adapted to tit into the grooved end of that-tube 7, and when forcgd into the tube, to press on the plate 10.
The rear end ot' the barrel is threaded to receive the end portion shown in Fig. l, which is formed with the cap 17, the screw 18 and the sleeve 1f). The inner side of this sleeve is threaded at a pitch preferably four times greater than the end of the barrel but in the same direction, and into it is fitted the screw 20, the head of which screw is the plate 16 above referred to.
The assembling of the parts and the operation of the pen are as follows; The tube 7 Jwith the plate 10 attached to it as described is fixed rigidly within the barrel and the sac (i insertedin the barrel, raising theplate so that it rests on the sac. The disk 16 with its screw 2O is l.inserted in the tube 7 and the end piece screwed into place in the barrel. Inasmuch as the ridges in the tube prevent the disk from rotating, when the operator unscrews the head 17 of the end piece and thus rotates the. sleeve 19, the screw /20 turns within the sleeve and is forced out of the sleeve a distance four times as great as the head 17 is moved. The disk is by this" means pushed into the tube and forces down the plate 10. This detiates the ink sac,'and when the head is turned back into place, the sacy will suck up ink through the feeding tube.
The modication shown in Fig. 5 consists in the elimination of the four to one screw, and the attachmentof the disk 16 to a pin 21 which is adapted to slide back and forth in an opening 22 in the head 23 which screws into the end of the pen barrel. `When it is desired to operate the del'iating plate, the user may push in the pin, thereby bringing the disk 16 into contact with the plate and forcing thc plate down onto the rubber sac. The actionof the sac in filling itself with ink raises the plate and forces the disk and piu back into normal position ready for another' operation.'
1n the modification shown in Fig. t3, the. head 25 is cored out as shown by the dotted 'lines at 26, and a plunger 29 is inserted, adapted to move back and forth in this cored out port-ion. ,A slot- 24 is cut in the side of the head 25l and the plunger 29 is provided4 with a pin 27 which projects throughk the slot. The end ot the detlatiiig plate l0 is extended at QS and attached to the plunger 29 by aloose connection 30,- lilie a iiiortise and tenon joint. In operating the deliating plate in this construction, the user 'presseS forward the pin 27, thereby pressing doivn the detlating plate. He then pushes it back again, allowing the rubber sac to till iiselt'.
-Besides providing a simple ineeliaiiieiil ineans for actuating iiiy'detlzitiiig plate, l also provide in ii'iy plate iin efficient inc-uns for detlating the sac. The plate, being hung on a plurality ot' hinges ot equal length, swings iii a plane Constantly parallel to the axis otY` the ink suc, thereby pressing out' the sac smoothly and completely.
Having thus described niy invention, what. l oiiiini as new and desire to secure by Leliters liilent, is:
l. In a selt-filling'fountain pen, a liexible sae ink reservoir, -a hinged plate for deflat- 2. In a self-lilling fountain pen, a flexible sae ink reservoir, an inner tube yin tlie pen barrel i'iusli with the inner surface thereof,
a plate foi dellatirig the sac, annular grooves in the inner tube, with transverse slots tlieiein, a plurality ot links between the plate and the tube, with the ends ot the links projecting' iiito said slots, :ind rings in. the grooves loting-fige the links and provide a hinge coin.
Corfies of this patent may be obtained for lfive cents each, by addressing the Commissioner of Patents'.
