4 claims. (oi. 120V-1) i This invention relatesto improvements in inkstands or pensets and more particularly tofsuch sets in Whicha .pen is supported with its pen. point immersed in ink and the pen held in readily v accessible position from which it may'bewithdrawn for vinstant use. v This application is,l in part, a continuation of my co-pending application Serial Number 84,809, filed vJunel2,ll936, nowPatent No. 2,147,931, lu dated February 21, 1939.

The mainv `objects of the invention are to provide an improved, durable and efficient ink holding receptacle; to provide means for holding a pen in predeterminedy accessible position with its point N?. `normally immersed in ink and for holding the pen in such `a way that ink Willnot accumulate on the inside walls of the pen supporting member or on the end 'portion of the pen holder; to -provide an improved ink holding `receptacle and 20 improved pen supporting means of the character indicated which will be easy tov manufacture and incorporate in an inkstand; to provide such an improved device' which may be constructed economically and ata cost within commercial practioability soas to insurethe usefulness thereof; and, in` general, it is the object of the device to provide animproveol inkstand of the character indicated. 'c Other objects and advantages of the invention Will'be understoodby reference to the following 'specification'and accompanying drawing, Wherein there is illustrated an -inkstand embodying a preferred form ofthe improved construction.v

In the'drawing: v Figure 1 is 1a sectional view'through `an inkstand of the pen-in-ink type; Figures 2 and 3 'aresectionson the lines 2-2 and 3--3, respectively, of` Figure1;gand

Figure 4 is a perspective 'of an improved socket "402 element comprising a portion of the improved same being' preferably molded of a suitable composition of hard'rubber or other plastic material 5s jf which will effectively resist corrosion byink.'

` One way of manufacturing the structure is tov `provide a mold holloWed out' to conform to the' exterior shape of the lmain and auxiliary-receptaclesi and 6 and to line such a mold withun-` curedo-r'partiallycured plasticmaterial'of the 5 selectedl composition. The mold may be lined with a single sheet ofthe material or with separate sheets'cut to facilitate the pressing ofl thesheets into 'intimate contact with the walls ofthe las a separate element, and in order to support the 16 intermediate'wall against sagging or `collapsing while the' material is in a plastic state, it is builty up around a reinforcing plate il of suitablesheet metal.l When the mold is thus lined and supplied with the partsforming the intermediate vwall 'L` 20` a small amount of `watery may be placed in` the dome-shaped portion Sand the bottom forming sheet of the receptacle applied to close tlrielined mold. A suitable mold cover may thenbe applied to close the mold whereupon it issubjected 25 to'suitable heat treatment for curing .the-plastic composition. The heat changes the water into steam ,-to develop internal pressure for pressing the receptaclefmaterial into intimateengagement With thewalls of the mold and also to insure 30`v union of the vseparate parts of which the device may 'be formed. The rnetal'reinforcingelementy 9 v .is important in the construction of the device in,v

that itsupports the partition wall until the 'latter becomes firm or set incident to the curing opera- 35 I tion," after whichVthe reinforcing plate is not of"v importance. l, i v l l The y*hollowl molded structure thus formed may then have an openingy It bored in the top wall of the auxiliary receptacle part 6 to receive a sleeve- 40 like socket il. As shown,'the openingjiil is bored to position thel socket Il at an angle so that a penl I2 supportedqby the socket Il will be held.'v in an inclined,` readily accessible position. The socket Il `may also be formed of a suitable grade of hard rubber which resists l'corrosion by ink andl it includesv upper'and lower portions i3 and 14,'

respectively. f

The upper portion I3 has its mouth flared 'as y indicated at I5`to facilitate insertion and jcenter-` 5o' ing of the lower end, I6 ofthe pen. .The upper portion of the socketis also provided with a series 'ofcircumferentially spaced, inwardly extending ribs 2U, the same extending lengthwise the .Socket 'fer 'about one-half as, enga. i

e as

The pen- I 2 comprisesa holder Il and a pen point I8, the latter being seated in the lower end portion of the holder in any suitable manner, for example, as shown in my United States Letters Patent No. 1,915,338, issuedJune 27, 1933. As shown in Figure 1, the lower end portion of the holder I'I is provided with a reduced diameter extension I9, the same being of slightly less diameter than the inside diameter of the inner edges of theribs 20, so that said reduced end portion I9 does not engage or seaton said ribs. The shoulder-formed end I6 of the holder II is, however, adapted to engage said ribs 2l! so that the socket and holder may be said to have circum-4 ferentially spaced points of interengagement.

The lower portion of the socket I@ is of slight-r ly tapering diameter as shown, and of such internal diameter that the pen point I8 lis adapted lto engage a portion of the socket as shown at ZI when the shoulder I of the holder is seated on theribs 20 in the upper portion of the socket. Hence, the .upper and lower socket portions com operate to support the pen in predetermined in` cline'd position as shown.

Ink from the main receptacle 5 flows into the auxiliary receptacle 6 to the height permitted by thenheight` of the passageway 8, it being under- `stoodthat air may enter the main receptacle 5 vonly when permitted toA do so through the auxiliary receptacle E` and the passageway 8. Hence, a substantially constant level of ink will be maintained in the auxiliary receptacle 6. As

shown in the drawing, the pen supportingy socket II is soy proportioned and seated in the inkstand thatthe pen point will normally be immersed in ink. jUpon withdrawal of the pen from the inkstand, the pen is immediately ready for use.

In prior art devices it has been more or less customary to position apen in a socketby providing the pen holder with an extension fitting in the upper portion of the socket so as tov constitute a stopper to prevent evaporation of the ink when the pen is in place. In such constructions it has been found that ink accumulates on the surface of the pen holder extension and on the insidewalls of the socket withth'e result that the pen holder becomes `bound to the socket and can be removed therefrom only with difliculty. For. the same reasons it vbecame diflicultto re-` insert the pen after use, It has beencoinm0nlyv assumed that the cause for such accumulation of inkwas due Ato the wiping of ink from the pen point'onto the inside walls of the socket and from thence to the pen holder extension,l However, I have found that even though a pen holder is ,carefullyl insertedand withdrawn so as to prevent such wiping of ink on the walls of the pen' socket, the pen holder would'nevertheless in time become bound in the socket as stated'. Ihave ascertained that this'results largely from the condensation on the Walls of the socket of ink vapor, rising from the surface of the ink Ysupply in the receptacle 6. Such vapor also penetrates to the smallest crevices present between the' walls of the socket and a pen holder extension vsuch as abover referred to, and much of it condencesand dries with the aforesaid results.

In the improved structure above described, a provision is made by means of theribs 21')l andthe resulting open passageways 2| between-the adjacent ribs to permit the free passage. of ink" vapor from the receptacle 6. By permitting the ink vapor to escape easily, practically no condensation occurs, with the result that the pen is kept clean brief, -the new structure maybe said to be a ventilated structure which prevents vthe fouling which occurs in conventional structures of' the 'l prior art.. The small amount of ink lost through vaporization and ventilation as explained is negligibleand yin any event is more than coinusefulness of the improved structure.

explained, the lower portion of the socket is provided with openings 22 which fare so positioned as to be at least partially above lthe normal level of ink inthe auxiliary receptacle 5.

lSaid openings are also preferably lpositioned y within about one-half the circumference of the socket so as to provide an adequatearea of unbroken, smooth surface on the. remainder of the said pen point. e y y Changes in the describedl structure may be made without' departing from-'the spirit ofthe vcircumference of the socket forl engagement by f invention, the scope of whichfshould be detercross-section so as tol provide ashoulder ad? jacent thevlower end ofthe holder,.,said socket comprising a sleeve-like member into which the pen point and said lower endvl extension of the k,
