DESK sm Original Filed June lO, 1958 7 ATTO/WWU Patented Mar. 1l, 1941 UNITED STATES PATENT OFFICE Original application June 10, 1938, Serial No. 213,056. Divided and this application October 21, 1939, Serial No. 300,635

9 Claims.

My invention relates broadly to desk sets and more particularly to an improved construction of desk set operating upon the principle of hydrostatic pressure for feeding ink to a dip pen well.

This application is a division of my application Serial Number 213,056, filed June 10, 1938, Patent Number 2,180,518, Nov. 21, 1939, for Desk set.

One of the objects of my invention is to proy vide an improved construction of hydrostatic 1 desk set which facilitates quantity production at relatively W cost.

Another object of my invention is to provide a construction of hydrostatic desk set formed from a minimum number of parts capable of 1 being molded from a variety of synthetic materials.

Another object of my invention is to provide a construction of moldable desk set having a minimum number of parts with the pen receiv- 20 ing guide formed integrauy with the molded structure of the desk set.

Still another o'bject of my invention is to provide a construction of desk set operative upon the hydrostatic principle in which the quantity 2,5 of the ink supply in the receptacle into which a dip pen is adapted to be submerged is restricted in comparison with the quantity of ink supplied to the receptacle by the hydrostatic pressure.

Still another object of my invention is to provide a desk set having a minimum number of interengaging parts and in which the line of division of the parts may be wholly obscured in the process of manufacture of the parts and a unitary appearance imparted to the desk set for improving the esthetic qualities thereof.

A still further object of my invention is to provide a construction of molded desk set in which a pressure equalizing aperture is molded directly into that part of the desk set which also vunites integrally with the pen receiving guide in the desk set.

Still another object of my invention is to provide a desk set formed from intertting ceramic 45 members that are joined and glazed so that the annular seam between the members is substantially invisible.

Other and further objects of my invention reside in the improved construction of molded 50 desk set as set forth more fully in the specification hereinafter following by reference to the accompanying drawing in which:

Figure 1 is a side elevation of a desk set constructed in accordance with my invention; Fig. 2

55 is a central vertical longitudinal sectional view or threaded inserts or gaskets dispensed with in 5-5 of Fig. l; and Fig. 6 is a cross-sectional 1"()` view similar to Fig.,2 showing the upper and lower portions of the base of the desk set illustrated in juxtaposition.

The improved desk set of my invention is the result of extended research and development in the art of desk sets operating upon the principle of hydrostatic pressure of the cla-ss set forth in my Patents 2,026,529, granted January 7, 1936; 2,112,907, granted April 5, 1938; and 2,148,941, granted February 28, 1939.

In my improved construction of hydrostatic desk set, the parts are reduced in number by molding the principal parts integrally as a unit from synthetic moldable material. The pen receiving guide through which a dip pen is adapted to be inserted isv molded integrally with the top portion of the molded base structure. I have found that it is wholly unnecessary to construct the guide for the dip pen independently of the base structure for in the improved ar- 3 rangement of my invention the socket constituting the pen guide is integrally molded with the upper portion of the base structure. The pressure equalizing port is molded directly into the upper portion of the base structure. 'Ihe central bore through which the threaded neck of the ink supply bottle extends is provided with screw threads molded directly into the material of the upper portion of the base and all bushings establishing connection between the ink supply bottle and the upper portion of the base.

The quantity of ink in the pool orv reservoir into which the point of a dip pen is adapted to quantity of ink maintained in |better writing con- 50.

dition than is the case when a larger quantity of ink is maintained in the ink pool. The parts o-f the desk set are molded from synthetic material of various kinds such a5 Resinox, Tenite,

porcelain, Bakelite and other phenol condensal ceiving socket tion products. I may mold the parts of the desk set from glass or other transparent material. Two principal parts are required; that is, the lower -base portion which receives the ink supply and the upper base portion which provides telescopic interengagement with the lower base portion. In ,constructions where the division between the upper and lower portions of the base is substantially transverse, the exterior cylindrical wall is treated with al fusible material which enters the transverse division between the upper and lower portions of the base and after being fused and baked, presents a substantially invisible seam which'when coated presents `an esthetic and ornamental appearance. In arrangements where the upper` and lower portions of the base telescopically engage for substantially the entire depth of the base, the cemented joint is entirely invisible when the vbase is viewed in side elevation. The restricted ink pool into which the dip pen may be inserted may be molded integrally with the lower portion ofthe base. The principles of my invention may be carried out in various embodiments and the form set forth herein is to be considered in the illustrative sense and notin the limiting sense.

Referring to the drawing' in detail, reference character I indicates generally the base of the desk set of my invention comprising a lower portion 2 and an upper portion 3 which are cemented together at their interengaging peripheries by suitable fusible material indicated at 4l in Figs. 2 and 5.

The lower.portion 2 of the base I is provided with a recessed reservoir 5 for containing the ink pool into which the dip pen is adapted to be inserted. The upper peripheral edge of the recessed reservoir 5 is beveled as indicated at 6 which allows the angul-arly disposed wall of the integrally molded pen` re- IES to.eXte`nd downwardly into the recessed reservoir 5 without obstruction. The lower base portion 2 is provided with an annular ledge 'I within the limits of which the recessed reservoir 5 is formed and above which the periph-r4 eral shoulder 8 on thelower portion 2 of the base projects. l

- The upper portion of the base 3 is provided with an annular depending wall 9 which telescopically engages within the peripheral shoulder 8 and extends toward the annular ledge 1. The upper portion 3 of the base' is provided with a central circular top ID from which there depends a central cylindrical portion Il. The central cylindrical portion II isrecessed as indicatedl at I2, the recess I2 terminating in a shoulderA I3. The internal bore of the central depending cylindrical portion II ,is screw threaded as indicated at I4 for receiving screw threads 23 formed on the neck of the ink bottle 22 in the inverted position illustrated in Fig. 2. The upper portion of the base 3 is provided with an integrally formed vent I5 serving as a pressure equalizing port in the hydrostatic operation of the desk set. 'Ihe dip pen' receiving socket is formed integrally with the upper portion of the base 3 as represented at I6. The pen receiving socket projects upwardly from the upper portion 3 of the base as indicated at I'I for receiving the dip pen which I have `shown generallyl at 26. The pen receiving socket i6 comprises the upwardly projecting integral portion I1 which is substantially frusto-conical in shape, the cylindrical portion I9, the frusto-conical portion 29, and the restricted cylindrically aperturedv portion` .2|v through which the pen point 30 of the dip pen pen holder is not being carried in the hand of the writer. Accordingly, dust and foreign matter are excluded from the pool of ink 3| in the recessed reservoir 5.

The ink bottle 22 has the screw threads 23 thereof engaged with the integrally formed screw threads I4 in the upper portion 3 of the base. A peripheral abutment 23a on the neck of the ink bottle serves as a stop for supporting the ink bottle 22 with respect to the shoulder I3 in the central recess I2. The neck of the ink bottle 22 has a restricted aperture 24 therein through which a restricted flow ofA ink under hydrostatic pressure is supplied to the pool 'of ink 3| from the supply of ink in the bottle 22. .A suitable protective and ornamental cover 25cis provided.

over the ink bottle 22.. To facilitate the mounting of the desk set on a supporting surface, I iray provide adhesive pads shownr generally at In the manufacture of the desk set shown in Figs. 1 6, the lower portion of the base 2 is telescopically fitted about the annular depending wall 9 with the fusible material 4 therebetween. 'Ihe parts thus prepared are subjected.

to a fusing and baking operation which lresults in the fusing of the joint between upper portion 3 and lower portion 2 of the base. v This joint is substantially invisible. Then the base is dippedor sprayed or otherwise coated with ornamental glaze or pigment, which enters the seam at the annular joint and the joint becomes wholly invisible `and the base appears as a single unitary member, A pleasing and esthetic appearance lis provided because a streamlined effect is ob,`

tained by ornamenting the surface of the upwardly projecting integral wall Il of 'the pen receiving socket, which ornamented surface continues without interruption throughout the entirecylindrical side wall of the base I. v

The screw threaded end of the ink bottle 22 is. engaged in the screw threads molded into thev upperportion of thel base structure to a position in which the ange'on the ink bottle abuts with the shoulder on the upper portion of the base structure. The cylindrical cover member is then inserted over the ink bottle 22 and the hydrostatic desk set is ready for operation. Because of the relationship of the pen receiving socket with respect to the pool of inkbelow the restricted orifice of the ink supply bottle, a continued supply of ink may be dependedupon into which the point of the dip pen is inserted from. time to time during writing operations. The

pressure equalizing port I5 insures a. continuous supply of ink from the ink bottle to the pool beneath the restricted orice 24 under control of hydrostatic pressure.

I have found the improvements of my inven-y tion highly practical and efficient in operation but I realize that modifications may be madev and I intend no limitations on the invention 'eX-'-y cept as may be imposed by the vscope yofv the appended claims.
