Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed October 25, 1910. Serial No. 588,947.

To all whom it may concern:

Be it known that I, IRVIN RosnNrELD, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Inkstands, of which the following is a specification.

This invention relates to an ink stand of novel construction, which maintains the ink at a uniform level and prevents access of the air to the main bulk of the ink. In this way cleanliness and accuracy in the supply of ink to the pen point is insured, while objectionable thickening of the liquid owing to rapid evaporation is prevented.

In the accompanying drawing: Figure 1 is a plan of an ink stand embodying my invention; Fig. 2 a vertical longitudinal section thereof on line 2-2 Fig. 1; and Fig. 3 a plan with the fountain and cover removed.

Two parallel side pieces 10 corrugated at 11, to constitute a pen rack, are connected by an intervening raised plate 12, the whole made preferably in a single casting and forming a frame. Plate 12 is provided with a sunk compartment or well A having the shape shown in Fig. 3. That is to say it comprises a circular rear portion 13, and a communicating narrow duct 14:, which is somewhat widened at its forward end to constitute a dip 15. Upon plate 12 is seated a cover 16, the front and rear ends 17 of which are removably sprung around the correspondingly beaded edges 18 of plate 12. Cover 16 has a circular rear aperture above rear well section 13, and a front aperture 19 above dip 15. This front aperture is of approximately elliptic shape to constitute a wiper for the penintroduced into the well, and it is arranged in alinement with two opposed corrugations 11 of side pieces 10. In this way a pen holder 20 when placed upon the rack will close the aperture and exclude air from the well.

Into the rear opening of cover 16 is fitted an upwardly extending threaded sleeve 21.

This sleeve is adapted to removably engage the threaded neck 22 of a normally inverted ink reservoir or fountain 23, which is preferably of globular shape as shown.


correlation of the parts is such that when neck 22 is screwed into sleeve 21, the distance between its open lower end and the bottom of well A, will determine the heightof the liquid level desired within the well.

Fountain 23 contains a valve 24 which closes neck 22 when the fountain is reversed, and which is adapted tobe unseated by a pin 25 extending upwardly from bottom of well A and of a length to lift the valve when the fountain is screwed home.

In use fountain 23 is righted, filled with ink and is then reversed and screwed with its neck 22 into sleeve 21, when valve 24 will be lifted in the manner described to establish a permanent communication between fountain and well. The ink will thus flow within the latter along channel 1 1 to dip 15 so as to be freelyaccessible to the pen. As air cannot flow into fountain 23 when the ink in well A closes the mouth of neck 22, any overflow of ink is obviated, while furthermore but a limited quantity of ink will be at all times contained in the well. In this way any excessive evaporation and consequent thickening of the main body of ink is prevented, so that the ink will remain in perfect condition until the fountain is entirely emptied, Furthermore as the ink in well A will be replenished from fountain 23 proportionately as it is used up, the liquid in the well will always stand at a uniform level, so that the pen cannot take up an undue quantity of ink.

I claim:

An ink well comprising a frame having a depending well provided with a circular rear section, a communicating central duct and a forward dip, a cover removably secured to the frame and having a rear aperture above the rear well section and a front aperture above the dip, a sleeve on the cover around the rear aperture, and an ink fountain having a depending neck that engages the sleeve.
