GUSTAV J. SENGBUSCH, OF MILWAUKEE, VISCONSIN..
SPECIFICATION forming part of Letters Patent No. 726,194, dated April 21, 1903. Application filed November 1, 1902. Serial No- 129,732. (No model.)
To all whom it may concern: Be it known that I, GUSTAV J. 'SENGBUSOH,
a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and Stateof Wisconsin, have invented new and useful Improvements in Inkstands, of which the following is a specification.
This invention relates to automatic inkstands, especially those havinga floating feedcontroller 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 several parts, which will be more fully hereinafter described and claimed.
In the drawings, Figure 1 is an elevation of an inkstand embodying the features of the invention. tion of the same. Fig. 3 is a horizontal sec tion taken in the'plane of the line 3 3, Fig. 2.
Fig. 4 is a horizontal section taken in the plane of the linea 4, Fig.2. Fig. 5 isa detail elevation of a closing device for the improved inkstand. Fig. 6 is a detail perspecti ve view of an ink-chamber which'is' deta'ch-' ably connected to the closing device. Fig. 7 T
is a detail perspective view 'of a -feed-controller forming part of the improved device. Similar numerals of reference'are employed to indicate corresponding parts in the several" views.
The numeral 1 designates the body of the improved inkstand, which is formed of suitable material, preferably glass, and has a chamber 2 therein for receiving ink. In the present construction a part of the bottom 3 of the body of the inkstand is elevated and Fig. 2 is a transverse vertical sec-' 10, having a lower horizontal flange 11 with a screw-threaded periphery. The inner portion of the neck 10 is constructedwith a se- .ries of ribs 12 (see Fig. 3) to provide grooves '13,through which ink is vertically forced in :a manner which will be presently set forth. The neck 10 at a point adjacent to the bottom-of the member 7 is formed with an airvent 14, through the medium of which the chamber 2 is regularly supplied with air through the member 7. At the point of intersection of the neck 10 with the bottom of the member 7 an inwardly-projecting circumferential stop 15 is located and surrounds the lower contracted opening of said member. Removably attached to the flange 11 of the neck 10 is an ink-chamber 16, which rests in thedepressed seat 4 constructed in the bottom of the body. This ink-chamber has aseries of vertical ribs 17 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 formed to establish communication between the chamber 2 and the The closure 6 as an entirety and the chamber 16 will be preferably formed of glass, though other material may be used, and within the neck 10 and the said chamber 16 a buoyant feed-controller is located and comprises a vertical pressure-tube 19, with a closed top 20' and the lower hollow float 21, with which-said tube communicates. This feed-controller is preferably formed of hard rubber, and before it is disposed in theink stand has air forced t hereinto to render it buoyant. The diameter of the pressure-tube 19 is approximately equal to the'distance between theribs 12 of the neck 10 and closely engages said ribs, and the diameter of the float 21 is about equal to the distance between the ribs 17 in the chamber 16. The feed-controller is readily 'depressible, and after pressure is relieved therefrom it will rise to a normal position or so that the upper closed end of the pressure tube 19 will bear against the stop 15, and when in this position the bottom of the float 21 is above the opening 18in the feed-chamber 16 to permit the ink from the chamber 2 to regularly flow or feed into the said chamber 16 proportionately to the amount of ink used. .1 I
The neck 10 is secured to the upper end of the chamber 16 after the feed-controller has been disposed in the said neck and chamber, and ink is then poured into the chamber 2 in any quantity desired,and it will be understood that said chamber may be completely filled up to the level of the air-vent 14:. The closure carrying the remaining part is then disposed in the opening 5 and secured in place, the diameter of the chamber 16 being such as to readily pass through the said opening. The ink flows from the chamber 2 through the opening 18 into the chamber 16 and raises the feed-controller to normal position, and the upper closed end 20 of the pressure-tube 19 is held in close relation to the stop 15, thereby preventing the entrance of dust into the ink or evaporation of the latter.
In the use of the improved inkstand the pen is applied to the closed top 20 of the tube 19 and the controller forced downwardly, and the pressure of the float 21 on the ink in the chamberlG will cause said ink to rise through the grooves 13 of the neck 10 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-vent 14 is cleared, and when the pen is released or removed from the upper closed end 20 of the tube 19 the controller assumes its normal 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 sufficient to dispose the controller in normal position as long as the inkinthechamber2 and seat 4 is above the level of the opening 18. The flange 11 is of material importance in the operation of the improved stand in view 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 distance between the upper surface of the top 20 of the pressure-tube 19 and the top of the float 2l,and when the closed top 20 of the tube 19 is in engagement with the stop 15 the top of the float 21 will bear against the under side of the flange 11. 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 pressure-tube 19 except through the grooves 13. \Vheu 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 13. By the employment of the 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, as well as proportions and dimensions, may be resorted to without departing from the spirit of the invention.
Having thus fully described the invention, what is claimed as new is 1. An inkstand of the class set forth comprising a body, a closing member therefor having an opening therethrough and a depending tubular neck with a lower horizontal flange, an ink-chamber connected to said flange and having communication with the body, and a feed-controller movably mounted in the neck and ink-chamber, the said controller comprising a vertical pressure-tube, and a lower float.
