To all whom it may concern: Y

Be it know-n that I, GUsTAv J. SnNGBUsoIr, a citizen of the United States, residing at` Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Inkstands, of which the followingr is a specification.

' This invention relates to automatic fountain-inkstands, especially those having a iioating feed-controller or buoyant stopper which obviates the entrance of dust or dirt into the inkstand-and prevents evaporation of the ink and at the same time permits ready access to the ink for dipping a pen.

The invention consists in the construction and arrangement of the severai parts, which will be more fully hereinafter described and claimed. c i

In the drawings, Figure 1 is an elevation of an ink'stand embodying the features of the invention.- Fig. 2 is a transverse vertical section of the same. Fig. 3 is a horizontal section takenin the plane of the lineBB, Fig. 2.

Fig. 4 is a horizontal 4section taken in the plane of the line f1.4, Fig, 2. Fig. 5 isa deproved inkstand. Fig. 6 is a detail perspective view of an ink-chamber which .is detachablv connected tothe closing' device. Fig. 7 is a detail perspective view of a feed-controller forming part of the improved device.

Similar numerals of reference are employed 'j to indicate corresponding parts in the several views.

The numeral 1 designates theV body of the 'improved inkstand, which is formed of rsuitable material, preferably glass, and has a main chamber 2 therein for receiving inkl lIn the 1 present construction a part of the bottom3 of the body of the inkstand is elevatedand at thecenter is depressed to providel a seat 4.

TheJ top of the body 1 has@ Opening 5 there' in to receive a closure 6, having'- an upper funf/ nel-mouth lmember 7, formed with aperipheral shoulder 8, between which and the wall of the lopening a rubber or Aother securing gasket 9. is .interposed to. form atight Jolnt and prevent the entranceof air into the body of the inkstand at this point. Depending centrally from the member 7 is a tubular'neck 10,

`having a lower horizontal'iange 11 with a screw-threaded periphery. The inner por- ;tion of the neck 10 is constructed with a series of ribs 12 (see Fig. 3) to provide grooves 13, through which ink is vertically forced in la manner which will be presently set forth. vThe neck 10 at a point adjacent to the bot- Atom of the member 7 is formed with an airvent 14, through the medium of which Vthe ichamber 2 is regularly supplied `with air through the member 7. Said vent also forms a restricted overiiow-passage through which ink'forced into the dip recess or chamber flows back to the main chamber. of intersection of the neck 1() with the bottom of the member 7 ian inwardly-projecting circumferential defiector-stop 15 is located and' surrounds the lower contracted opening of said member. Removably attached to the iiange 11 of the neck 10 is a fountain-chamber 16, which rests in the depressed seat 4:, constructed in the bottom of the body. This fountain-chamber has' a series of vertical ribs17 therein to serve as guides, and through one of the ribs and the adjacent part of the side wall of the chamber a feed-opening 18 is for-med to establish communication between the chamber 2 and the chamber 16 and Wherebyink from said chamber 2 may regularly feed into the chamber 16. The closure 6 as At the point` erably formedA of glass, though other mate- 1 rial may be usedandwithin the neck 10 and the said chamber 16 a buoyant feed-controller is located and comprises a vertical pressuretube 19, with a closed top 20 and the lower hollow iioat 21,-witli which said tube communicates. ,This lfeed controller is preferably formed of hardrubber and before it is d isposed in the inkstand has air forced thereinto to render it buoyant. `The diameter. of the pressure-tube 19 is approximately equal to the distance betweenthe ribs 12 of the neck 10 i i and closely engages said ribs, and the diameter of the oat 2 1 isabout'equal to the distance between the ribs'17 in the chamber 16.' The feed-controller is readily depressible, and 'afterpressure is relieved therefrom it will rise to a normal position or sothat the upper closed end ofthe pressure-tube 19 will bear againsv vent 14. So, also, as soon as the stop 15 and seal the dip-opening, and when in this posit-ion the bottom of the` float 21 is above the opening 18inthe-feed-chamber 16 to permit the ink from the` chamber 2 to regularl y flow or feed into the said fountainfchamber `16 proportionately to the amount ot' ink usm 'lhe neck 10 is secured to the upper end of the chamber- 16 after the feed-controller has feed-controller to normal position, and the upper closed end 2() of the pressure-tube 19is held in close relation to the stop 15, thereby preventing' the entranceorl dust into the ink` or evaporation of the latter.

1n the use of the improved inkstand the pen is applied to the closed top 2O of the tube 19 and the controller forced downwardly, and'the pressure ot' the float 21 on the ink in the cham-- ber 16 will cause said ink to rise through the grooves 13 of the neck 1() and become applied to the pen. The depression of the controller causes the float 21 to move over and close the opening 18, and at the same time the air-ventv 14 is cleared, and when the pen is released or removed from the upper closed end 20 of the tube 19 the controller assumes itsnormal position` and the used ink, or that taken from the inkstand, is replaced in the chamber 16 immediately after the elevation of the float 21, so that the ink in the chamber 16 is regularly maintained in quantity suilicient to dispose the controller in normal position as long as the ink in the chamber 2 and seat 4 is above the level of the opening 18. As soon as the feed-controller is depressed and the ink en'- ters the spaceabove its upper end the ink begins to How to the main chamber through the the controller beginsto rise the ink is drawn back through the grooves 13, so that `before the feed-controller has fully risen the ink has all receded 'from the dip-recess. The flange 11 is of material importance in the operation of the improved stand, in vie-w of the fact that it prevents the ink from spurting or being forced upwardly with too great pressure through the grooves 13 of the neck 10. Furthermore, the parts are so proportioned that the distance between the stop 15 and the under side of the flange 11 will be equal to the Vdistancei between the upper surface of the top 2O of the' pressure-tube 19 and the top of the oat 21,'

and when the closed top 20 of the tube 19 is Yin engagement with the stop 15 the top of the float 21 will` bear against the under side of the flange 11. Such construction economizes space in the fountain-chamber, but is n\ot essential. It will also be seen that the ribs 12 and 17 prevent the controller from having lateral movement, so that the ink cannot pass up between the neck 10 and the pressure-tube 19, except through the grooves 13. VVhe-n the controller is depressed, the float 21 causes the ink to rise between the ribs 17 and pass over the top 'of said float and then upwardly through the grooves 1,3. u air-vent 14 the return of the controller to normal position is insured by reason of the fact that suction is overcome or any tendency toward the formation of a vacuum which might hold the controller in depressed position is prevented.

The several parts of the inkstand can be readily separated for cleaning and changes in the form, well as proportions and dimensions, may be resorted to without departing from the spirit.of the invention.
