SETH S. CROCKER, OF WOLLASTON, MASSACHUSETTS.
FOUNTAIN-PEN.
Specification of Letters Patent.
Patented May 2, 19rd application led February 17, 1913. Serial No. 748,774.
a rubber sack is arranged in the pen-barreland connected to the pen-section, and is compressed to expel the air, and then is permitted to expand, while the pen is dipped 1n the ink, so that it may become filled.
VInasmuch as it is desirable that the capacity of the sack be as great as possible, it is advantageous to make the walls of the sack no thicker than is absolutely essential. As a rule, with the same quality of rubber, the thinner the rubber of which the sack is made, the less its strength to draw imp the ink by suction, so that, with prior devlces, the limit of thickness of the rubber is determined by the ability of the sack to draw up the ink by suction through its force of expansion.
In collapsing the sack by blowing from the lungs into the barrel, considerable inconvenience is sometimes experienced, especially when the barrel of the pen is short and the sack does not yield readily to the pressure which the person attempting to fill the pen is able to exert.
The object of my invention is to provide a simple and convenient means for filling the pen of the above described character, which may be readily applied thereto, and detached therefrom, and which will enable the sack to be compressed by mechanical force, in lieu of blowing into the barrel from the lungs, andv which will act to assistv the sack 1materially in sucking up the ink from the inkwell in which the pen is dipped, so that the sack will become filled. I accomplish this object by the means shown in the accomn panying drawing, in which,
Figures l and 2 are partial, central longitudinal sections, showing my device in different positions. Fig. 3 is a detail view of the lilling-device.
In the drawing a indicates the ordinary pen-section, and b the barrel in which the pen-section is fitted, the neck of the rubber sack c being connected to the inner end of the pen-section, and arranged loosely in the barrel, as is customary.
The end ofthe barrel is provided with a short projecting nipple or boss b in the middle line thereof and an aperture b2 is extended through said nipple, centrally thereo1", into the interior of the barrel. A rubber bulb 'al is provided, having a c'ontracted neck d which is adapted to be litted tightly over the projecting end of the nipple b', so as to connect the bulb to the interiorof the barrel, the rubber of which the bulb vis made being materially thicker and stronger than that of the sack. rdinarily the bulb d will be detached from the pen barrel, and when it is desired to fill the sack with ink, the bulb is slipped onto the nipple b', as shown in Fig. l; then the pen is dipped into the ink and the bulb is compressed, so that the air which was contained in the bulb will be forced into the barrel of the pen, causing the sack to be compressed in the manner shown in Fig. 2. rlhe pressure on the bulb is then relieved, so that it is free to expand, and, as the bulb is relatively stronger than the sack, it will tend to exhaust the air from the barrel materially faster than it would be expelled by the unassisted expansion of the sack. That is, the bulb acts to reduce the air pressure in the barrel, so that the air pressure on the surface of the ink will assist in forcing the ink up from the pen-section into the sack. The force of expansion of the sack will also assist-in sucking up the ink in the usual manner, but its walls may be made 'thinner and of. less strength than if the bulb were not used.
When the sack hasbeen iilled the bulb will be removed, so that the pen will be unobstructed thereby.
