Application nl, u, 1m, sum No. 15ans My .invention relates broadly to desk sets and more particularly to an improved construction of inkwell and arrangement of dip pen for use in coaction therewith.

One of the objects of my invention is to provide a construction of inkwell of the hydrostatic .pressure type which may be readily molded in `one piece from synthetic materials. f

Another object of my invention is to provide an inkwell of the hydrostatic type having an v4integrally molded base and ink reservoir supporting portion and including an integrally molded dip pen support capable of beingl manuactured inexpensively on a quantity production asis.

Still another object of my invention is to provide a construction of inkwell and integrally connected dip pen support by which the pen may be mounted in a convenient position at all times to allow withdrawal of the pen from a position substantially sealing the passage extending to theink reservoir for a convenient writing operation.

A further object oi' my invention is to provide mounting means for a dip pen in a hydrostatic linkwell in which a substantially frictionless bind is provided between a portion of the dip pen holder and the pen guide portion of the inkwell whereby a relativelyrtight seal ma be readily broken upon grasping and lifting the pen holder from the inkwell.'

A still further object of my invention is to provide an arrangement for mounting a dip pen in the pen receiving. receptacle of a hydrostatic inkwell in which coacting parts are provided in the pen receiving receptacle and on the dip pen so that the thrust of the pen upon insertion into the ink receiving receptacle is stopped at the mouth of the bore and a substantialseal established adjacent the mouth of the bore, the bore being arranged both as a guide and' a securing means in coaction with the dip pen supplied for use with the hydrostatic inkwell.

Another object of my invention is to provide a construction of pen guide for a hydrostatic inkwell 'wherein the bore of the pen guide is shaped to coact with a soft resilient rubber disc carried by the dip pen for insuring the sealing of the pen receiving receptacle against dust and other foreign matter tending-to interfere with the of the inkwell permitting the level of the ink in 'comme (0mm-ss) between the pen holder and the pen receiving receptacle.

A further object of my invention is to provide a construction of hydrostatic inkwell molded from synthetic v'material and including a pen re- I, ceiving receptacle and a compression escapement channel directly formed in the wall of the pen receiving receptacle.

A still further object -of-my invention is to provide a construction of molded hydrostatic inkwell which may be formed either wholly or partially from transparent material allowing the ink level in the inkreservoir to be readily dbserved from the exterior of the inkwell.

Other and further objects of my invention reside in the arrangement. of seal between the dip pen holder and the penv receiving receptacle as set forth more fully in the specification hereinafter following by reference to the accompanying drawings in which:

Figure v1 is a perspective view of the hydrostaticinkwell ofmy invention; Fig. 2 is a vertical sectional view taken through the inkwell illustrated in Fig. 1; Fig. 3 is a vertical sectional view taken through the inkwell on line 3-3 of Fig. 2: 2 Fig. 4 is an enlarged cross sectional view showing the position occupied by the dip pen when inserted in the pen receiving receptacle; Fig. 5 is a view similar to that of Fig. 4 but showing the manner in which the dip pen is removed from 30 the pen'receiving receptacle of the hydrostatic inkwell; Fig. 6 is a longitudinal cross sectional view taken through a modified form of inkwell embodying my invention wherein the inkwell is molded from transparent material, thusl render- 35 lance with lmy invention and' in vwhich a transparent panel member is insertable in one wall the ink reservoir to be observed at all times; Fig.

The hydrostatic inkwell of my invention is molded from synthetic materials in'one piece 50 which includes the integrally connected housing, base and intermediate pen receiving receptacle. The pen receiving receptacle has the axis thereor disposed on an acute angle with respect to the horizontal base. The lower end of the pen re- 55 portion 3 of base-2.

ceiving receptacle connects through a port with the ink reservoir. The funnel shaped entranceway to the pen receiving receptacle is shaped to v coact with the end of the dip pen holder and inof. The pen employed in coaction with the ink- 'well of my invention is mounted eccentrically with respect to the pen holder allowing a substantially frictionless seal to be eiected between the end of the pen holder and the pen receiving receptacle. 'I'he eccentric construction of the pen holder permits a relativelytight seal to be established between the pen holder and the pen receiving receptacle. The same can be readily broken however, without danger of sticking. The pen receiving receptacle and port at the lower extremity thereof is so shaped in coaction with the funnel shaped upper extremity of the pen receiving receptacle that upon insertion of the pen the thrust is stopped in the mouth of the bore of the pen receiving receptacle, thus protecting the pen point. Two zones oi abutment are provided between the shaped end of the pen holder and the pen receiving receptacle, that is, a substantially angular abutment between the end of the pen holder andthe interior cylindrical wall of-` the pen receiving receptacle and the angular abutment between the funnel shaped extremity of the pen receiving receptacle and a shaped portion of the dip pen. .For further increasing the seal, I interpose a soft resilient rubber disc between a portion of the pen holder and the ink receiving receptacle.

I may construct the housing of the inkwell wholly `from synthetic transparent material or removable panels may be provided in the walls of the housing, the panels having suillcient transparency to allow the level oi' the ink to be' continuously observed or the panels being formed from suitably colored material for lending ornamental appearance to the inkwell.

Referring to the drawings in detail, reference character I designates the moldedl housing -of the hydrostatic inkwell which is formed integrally with the horizontally extending hollow base 2. The horizontally extending hollow base 2 has a at portion which I have indicated 'at 3 which bears substantially flange-like relation to the housing I. The housing I includes not only the upwardly projecting portion I which extends above the at portion 3 of base 2 but also a downwardly projecting portion 4 integrally united with the housing I and base 2. The downwardly projecting portion 4 is smaller in the lateral cross sectional area than is the upwardly projecting portion. The downwardly projecting portion 4 unites with the upwardly projecting portion I through an intermediate shoulder 9 disposed in a plane substantially above the plane of the iiat The shoulder 5 provides a peripheral support for the inverted ink bottle which'I have shown generally at 6. The ink bottle 6 has a relatively narrow neck 'I which extends downwardly into the ink receiving reservoir 8 formed in the downwardly projecting portion 4 of the inkwell. The ink bottle is introduced into the open top of the inkwellby'removal oi' the top 9. The top 9 engages with the upper peripheral edge of housing I through the coacting peripheral portion Ia on housing I and peripheral portion 9a on cover 9.

Intermediate the base 2 and housing I, I providea pen receiving receptacle shown generally at l0. 'Ihe pen receiving receptacle is disposed on an axis which extends at an acute angle with respect to the horizontal base. The pen receiving receptacle has a rounded funnel shaped upwardly extending wall I 5 of the downwardly projecting portion 4. The lower .extremity of the frusto-conical section I4 is connected through port I6 with the ink receiving reservoir 8. The parts of the pen receiving receptacle III are proportioned in a very special manner for the purpose of supporting the dip pen in a manner which will be pointed out hereinafter in more detail.

The dip pen is shown as including a pen holder II, a portion of which is constituted by a hollow barrel portion having a compression release aperture I8 therein. The pen holder terminates in a chamfered shoulder I9 which coacts with the funnel shaped upper end portion shown at II. The pen'holder supports the cylindrical member 20, terminated in a rounded shoulder 2I which coacts with the interior oi the bore of the pen receiving receptacle IIJ.V The member 20 provides a carrier for the eccentrically mounted pen point 22 which is maintained in position in coaction with the ink feed member 23. .The eccentric mounting of the pen point may be readily observed by supporting the pen holder between the forengers with the pen point bearing against one forenger and ,the vend of the pen holder against the iorenger of the other hand and then twisting the pen holder, whereupon the eccentricity imparted to the pen by reason of the particular mounting thereof in member 20 will be readily apparent. This eccentric mounting is important as it allows the entry of the pen point into the pen receiving receptacle by the coaction thus so shaped as to insure a substantially dust tight seal for the inkwell. As the pen holder is -thrust into the pen geceiving receptacle, the nib of theipen at 24 is deeeted by the frusto-conical wall portion I4 of the pen receiving receptacle to guide the pen point into a substantially central position tending to move the shoulders I 9 and 2l into frictionless binding engagement with the funnel shaped extremity I I and the internal bore I0 of the pen receiving receptacle. The thrust of the pen is stopped at the mouth of thebore I0. An abutment is established between chamfered shoulder I9 and funnel -II and between shoulder 2l and the interior bore of pe'n receiving receptacle I 0. There is a tendency for a suction seal to be established when the pen is thrust vinto the pen receiving receptacle. This suction is broken however, if the lingers grasp the^pen holder and impart a slight angular movement thereto, rocking the pen holder in the pen receiving receptacle andbreaking the vacuum seal at one side of the pen receiving receptacle.

In order to further seal the pen receiving receptacle into which the pen holder is inserted, I

provide a soft resilient rubber disc 26 which is apertured at 26' to llt around member 20 below chamfered shoulder I9. When the pen`slides into the funnel shaped entrance II of the pen receiving receptacle, the rubber disc of its very nature conforms to the shape of the opening, sealing it against dust. Moreover, the soft'rubber disc 28 shields the fingers against contact with ink deposits on the lower section of the pen holder. .The soft resilient rubber characteristics of the disc are such that both the sealing function and the shielding function are readily performed by the disc.

I provide a compression escapement channel 21 intermediate the downwardly projecting portion l and the upwardly projecting portion I of" the housing. The compression escapement channel is disposed between the upper portion of the downwardly projecting wall I i and the front wall of the housing I. The compression esca-pement channel 21 extends between the upper portion of pen receiving receptacle .III and the interior of the housing I above the level of the ink in the ink receiving reservoir 8, insuring equalization 'of pressures in the hydrostatic inkwell and pen receiving receptacle.

I may provide a capillary for insuring the continuousfeeding of 'ink from the ink bottle i to the ink receiving reservoir 8. I have indicated the capillary at 2 8 having a branch portion 29 for insuring the continuous feeding of the' ink. In

Fig. 9 I have shown more clearly the construction of capillary wherein the upper portion thereof is substantially tubular and the lower portion is split into two semi-cylindrical portions, one of whichextends into the ink receiving reservoir 8 and the other of which extends upwardly into the ink bottle 6.

In order to permit observation of the s upply of ink in the ink bottle 6 I may provide transparent panel sections 30 or 3l in the front or rear walls of the housing I. The housing I is slotted and provided with grooves 30a or 3Ia into which the panelsll' or 3| having coacting tongues 30h or SIb may slide. The panels, or 3i, instead of being transparent, may be of colored material for imparting ornamentation to the inkwell.

I may construct the inkwell wholly from transparent lmaterial so that the supply of .ink in the ink bottle 6 is at 'all times readily observable andl also the inkwell provides a high ornamental appearance as a xture for the desk. The arrangement of the transparent inkwell is shown in Fig. 6 in which I have numbered all of the parts heretofore explained with (corresponding characters with a prime niark added thereto. 'Il'he same integral construction of the several parts including the base, the housing, the ink receiving reservoir, and the pen receiving receptacle is employed in the form illustrated in Fig. 6 as is the casein l the gures as heretofore explained.

I have found the hydrostatic inkwell of my invention highly practical in its construction and upwardlyprojecting portion with a shoulder intermediate said portions, an inverted ink bottle having a peripheral portion thereof supported by said shoulder, a closure for said container proi viding 'an air space around and above said bottle,

tially through said shoulder.
