FOUNTAIN-PEN FILLER.

Application led March 1S, 1920J Serial No. 366,793.

To all whom z' may concern.'

Be it known that l, lPnUL S. HAUTON, a citizen of the United States, and a resident of Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Fountain-Pen Filler, of which the following is a full, clear, and exact description.

This invention relates to fountain pens and particularly to an improved construction involving a filler, having for an object the provision of means wherein substantially full supply of ink is drawn in upon each filling operation.

Another object of the invention is to provide a filler which utilizes a threaded cap at one end of a fountain pen for actuating means for collapsing a flexible sack carried in the pen body.

A further object of the invention is to provide a filler having a collapsing mechanism for the ink sack and means co-acting with a threaded cap which will permit the cap to have an idle or dead motion for part A of the time during its operation in order to give the bag time to distend and draw in a full quantity of ink.

In the accompanying drawing: Figure 1 is a longitudinal vertical section through part of a fountain pen showing an embodiment of the invention.

Figure 2 is a vsection through Figure 1 on line 2-2.

Figure 3 is a sectional view through Figw ure 1 on line 3-3.

Figure 4 is a perspective view of the actuating member embodying certain features of the invention.

Figure 5 is a detail fragmentarw7 sectional w view through part of the presser bar showing the connection between the bar and the actuating member.

Referring to the accompanying drawing by numerals, 1 indicates a barrelcf substantially the usual kind provided with any desired kind of construction 2 which will act as a feeder for the ink and to which the pen is connected as well as the sack 3. The particular construction of member 2 and sack 3 forms no part of the present invention. Barrel 1 is threaded at the end opposite member 2 so as to receive the threaded. section 4 of the cap 5. Threaded section 4 is of some appreciable length so that the cap 5 mustbe rotated a number of turnsbefore Renewed April 15, 1921. Serial No. 461,680.

it is completely unscrewed or before it is screwed up tight against the barrel 1. A reduced neck or extension 6 extends from the cap 5 and is provided with a head 7, said neck 6 accommodating the apertured member or actuating sleeve 8 which is preferably formed integral with the actuating arm 9. The entire construction of the acituator 10 consists of the sleeve 8, the arm 9 and the connecting material which is provided with an aperture 11 for receiving a pivotal pin 11, said pin extending not only through aperture 11 but also through barrel 1. It will be noted that the sleeve 8 does not extend at right angles to the arm 9, but at a slight acute angle whereby when the cap 5 is screwed up against the barrel 1 or unscrewed therefrom there is a certain lost or dead motion before the threaded section 4 or the head 7 strikes the sleeve 8 for moving the same pivotally.

As shown in Figures 1 and 4 the arm 9 extends to substantially a position on the presser vbar 12 where the tongue or rojection 13 extends into an aperture 14 aving slightly beveled walls (Figure 5) whereby bar 12 will press against the sack 3 and may freely adjust itself to receive the sack. Arm 9 is also provided with a pair of turned down sections or ears 15 and 16 which bear against the upper surface of the presser bar 12 while the tongue 13 is slightly upset or enlarged at its lower end in order not to move out of opening 14 so that when the arm 9 is raised from the dotted position shown in Figure 1 to the full line position the presser bar will be also raised.

In operation, when the parts are in the position shown in Figure 1 and the sack 3 is empty cap 5 is unscrewed as far as possible whereupon the sack will be collapsed to its full extent.` As the cap is being unscrewed the dead or loose motion between the shoulder 7 and the sleeve 8 will be first taken up after which the sleeve 8 will be rocked on the pin 11 and the arm 9 will be swung downwardly to the dotted position. When this extreme collapsing position of the sack has been reached the resistance of the parts to the movement of the cap 5 will. indicate that the cap is unscrewed as far las permissible. The point of the fountain pen is then submerged in a supply of ink, said fountain pen being preferably in a substantiallywertical pod sition, cap 5fis then screwed back into'the position shown in Figure 1. As the cap is first rotated a few times the shoulder 7 will move away from sleeve 8 and permit the sack 3 to eXpand and raise the parts to the full line position shown in Figure l whereby a suction will be produced for sucking in a supply of ink. This movement ofthesack and associate parts occurs an appreciable time before the cap 5 has been screwed down tight, but the operator does not know that this is taking place and consequently continues to screw cap 5 down tight against the Asleeve thus allowing ample time for the rarefication in the sack 3 to suck in a full suply of ink and completely lill or substantiallyiill the sack. This is ofconsiderable advantage as the usual lever actuated fillers now in common use are operated quickly and then the pen withdrawn fromthe ink supply before the sack is given 'time to lill. This provides only a small quantity of ink while the person lling the penthinks a full supply has been secured. For thisreason frequent filling of the lever type of -llers is necessary solely on account of the-'ignorance of the `operator of the filling mechanism. `In the vpresent construction the loose ordead motion in screwing the capiback` against the barrel 1 permits Iample time for the bag to become filled as lthe* operator believes that the screwing down lof the cap is necessary and will consequently hold the end of the pen in the ink supply until thecap is in a closed position. y

VVhatI claim is:

l. In a fountain pen the combination with a barrel with a collapsible bag therein of collapsing means for said bag, and a ro tatable` screw member for operating'said collapsing'means7 said screw member'having a predetermined dead vmotion in moving iny both directions whereby the screw mem- ,ber must be rotated a number oftimes after the lbag has become distended and thereby allow sufficient time for the filling action tota-ke place.

' 2. A fountain pen filler.` comprising a presser bar,` a pivotally mounted filling arm,- anda screw member for actuating said presser bar, the connection between the screw member and the actuating arm being loose sothat there will? be apreciable lost Imotion of the screw memberr in both deflating and inflating.

In a fountain l pen the combination with a distendable' bag of a presser bar for collapsing said bag, an arm for actuating said presser bar, means for pivotally mounting salda-rm so thatthe arm will swing, a projection `extending from said arm,v and la screw cap adapted to bethreaded into thefen'd'l of the'barrel 'carrying said bag, *said* screw" cap: being 'provided with a reshoulder being spaced a sufficient distance from the cap to permit a predeterminedv dead movement'for .causing the operation of the cap an appreciable time after the bag has been released. v x
