Dec. 11,1945. G. J. sENGBUscH INKSTAND I Filed Feb. 5, 1944 [72verz Gzzsiav Jie'r zybusc/z Patented Dec. 11 1945 UNITED STATES PATENT OFFICE INKSTAND Gustav J. Sengbusch, Milwaukee, Wis.

7 Claims.
This invention relates to improvements in inkstands, and more particularly, to inkstands of the type wherein a relatively large supply of ink is stored in a receptacle and provision is made for feeding ink from such receptacle to a pen supported in an upright, readily accessible position by means of a socket into which the lower end of the pen fits.
The main objects of the invention are to provide an inkstand of the character indicated in which loss of ink by evaporation with its attendant objectionable crust formation is substantially eliminated; to provide such an inkstand which may be easily refilled from time to time as needed but which, under ordinary circumstances, will require refilling only at widely spaced intervals of time; to provide an inkstand having the above indicated characteristics which will be easy to manufacture and which may be produced and sold at a relatively low cost; and, in general, it is the object of the invention to provide an improved inkstand of the character indicated.
Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing wherein there is illustrated an inkstand embodying a selected form of the invention.
In the drawing,
Figure l is a plan;
Fig. 2 is a section on the line 22 of Fig. 1;
Fig. 3 is a bottom plan of a part of the inkstand, and
Figs. 4 and 5 are sections on the lines 4-4 and 55 respectively, of Fig. 2.
The improved inkstand herein illustrated embodies a base 6 having an upstanding cylindrical housing 1. The base 6 is designed to rest on a desk or table top and the housing 1 receives an ink bottle 8 which is placed therein in inverted position, that is to say, with its mouth end down.
The ink bottle 8 is provided with a cap or closure 9, which has a downwardly projecting boss l0 formed thereon adjacent one side. The cap is preferably threaded on the mouth end of the ink bottle, as indicated at H, a gasket l2 of cork, or other suitable material, being provided between the mouth end of the ink bottle and the inside of the cap to prevent leakage at that point.
The base 6 is provided with a bottom wall l3, which is recessed as shown at M, to receiv the lower end portion of the cap boss l0. At one side of the housing 1, the base is extended, as indicated at l5, to provide a socket [6 adapted to hold a writing pen I! in an upwardly extending angular position, as best shown in Fig. 2. The
pen point l8 of the pen extends through the socket l6 and into a transversely arcuate recess I9 provided in the cap boss l0. Said boss in is provided with a passageway 20 for conducting ink from the ink bottle 8 directly to the surface of the pen point which engages the transversely arcuate recessed surface H! in the boss I0.
In order that the pen II will normally be seated in the socket IS with the front surface of the pen point 18 in engagement with the arcuate surface 19, the socket I6 is provided near its inner end with a transversely flattened wall portion 2| which is adapted to co-operate with the fiat rear wall portion 22 of the feed bar 23 of the pen. The pen structure may be of the character shown in Patents Nos. 1,915,338 and 2,179,727, and is accordingly such that a small supply of ink will be retained by the feed bar 23 so as to enable the pen to write a large number of words without requiring clipping of the pen in ink, or frequent insertion of the pen in the described inkstand. The upper end portion of the socket may be provided with a series of relatively spaced ribs 24 for centering the lower end of the pen holder relative to the socket. Said ribs co-operat with the boss Hi to support the pen in the angular, upwardly extending position shown, since the pen normally tends to fall by gravity to a horizontal position, thereby causing the pen point [8 to engage against the arcuate recessed wall IQ of the boss I0.
The co-operating fiat surfaces 2| of the pen socket and 22 of the pen feed bar serve to cam the pen in a rotary movement about the axis of the pen upon insertion of the pen into the socket. It is, of course, possible to insert the pen into the socket in such a position that the feed bar 23 will not initially engage the flattened portion 2|, but in that event, it will be readily noticeable that the pen cannot be properly seated in the socket. When the pen is properly seated, it is held quitefirmly against wobbling, and it extends upwardly in a concentric relation to the axis of the socket.
The ink bottle 8 is preferably supported in the base 6 and housing I by means of a shoulder 25 provided in the base and on which the peripheral portion of the cap 9 rests when the ink bottle is in operative association with the base. The boss Ill preferably terminates in slightly spaced relation to the bottom of the recessed portion M of the base, although it may extend downwardly to engage said bottom, if desired. A cover 26 may be provided for closing the upper end of the hous ing. 1, said cover being preferably detachably connected to the housing in any convenient manner such as illustrated.
In the described inkstand construction, ink is fed directly from the ink bottle 8 through the passageway 20 to the pen point. The passage 20 I may be so arranged that it communicates, at least in part, with the usual hole and split in the pen point, such hole being indicated at 21 in Fig. 5. Capillary action between the inside surface of the pen point and the feed bar 23 serves to cause ink to enter the ink retaining slots of the feed bar to thereby provide the pen capacity for extended writing without frequently replenishing the ink supply tolthe pen. point. In the practical opera-. tion of the structure, it is found that ink will ulti; mately seep downwardly between the pen point and the arcuate wall I9 of the boss I0, and into the recess I l. However, the pen point continues to receive its supply of ink directly from the ink bottle and thus, at all times, is in contact with a supply of fresh, free-flowing ink which aids the pen in the proper performance of its writing func-,
tion.
It may be observed that although the discharge end ,of the ink duct 20-is located above the surface- 28 of the bottom wall IQ of the base, ink does not ordinarily flow over said bottom wall l3. This appearsto be due to the fact that the duct 20 is of a sufiiciently small diameter to provide enough resistance tothe flow of ink therethrough. The pen point itself tends toattract ink from the discharge end of the duct 28,, and to that extent assists theflow of ink therethrough, but the assistance thus provided is not suficient to cause a free flow of ink. Only the ink demanded by the pen point and its feed bar will flow out, especially after the recess [4 has been substantially filled with ink to thereby eliminate the capillary eiTect of the lower end portion of the pen point and the portion of the wall I 9 of the boss 18 engaged thereby.
It will also be observed that thesurface of the pen point extending acros the discharge end of the ink duct 28 tends to close the same. Although theclosure of the duct by the pen point is not a perfect seal, it is, nevertheless, usually tight enough to. add materially to the resistance of the ink duct 26 to prevent the free flow of ink through said duct. Movement of the .pen into and out of the, socket I6. serves, of course, to more or less agitate the ink at the discharge end of the duct and to thereby cause a small amount of ink to flow outof the duct.
It has been found, however, that over a. long period of use ink does ont overflow the recessed chamber it except under atmospheric or temperature conditions which result in sufficient air pressure within the ink bottle 8 to force out an excess amount ofink, which then overflows the surface 28 f the bottom wall l3 which then acts as the bottom of anoverfiow chamber.
It, has also been found over aconsiderable period of experience with a device constructed as herein described and illustrated, that when atmospheric and temperature conditions become normal, any ink in the overflowchamber will be returned to the ink bottle 8 by reverse action. Such return of the ink may perhaps be explained by the suction action resulting from a reduction in the air pressure within the inkvbottle relative to the air pressure outside thereof, and by the fact that the pen point normally maintains a film of ink across the discharge end of the duct so that air does not normally have access to the duct 20. Hence, inkandnotair will enter the inkwell when atmospheric conditionscausing flooding of the overflow chamber are restored to normal.
To prevent ink from flowing upwardly on the outer surfaceof the penpoint from thedischarge end 2 9o f the duct the concave recessed surface i9 is; additionally recessed asindica ted at 30 to provide such spacebetween thesurface of the pen point above the dischargeend ofthe duct and the a en id v s e- Q he. ependinsn oieo ion III, that there will be no capillary flow of ink upwardly at that point.
Changes may be made in the structure described without departing from the invention.
