This invention'relates to pen supports for receiving and supporting a pen'in upright and conveniently accessible position. The principal object of my present invention is to provide an improvedpen support'which is adjustable so that it is' capableofreceiving and supporting various sized penholders. More specifically; theobject of my invention is to provide a pen support in which the lower end of the penholder is seated on aseat and serves toclose an opening into or through which the pen point projects together with adjustable means for aligning the penhololersubstantially co-axial with the seat on which the penholder restsso that the end of the penholder will engage the seat around substantially the entire circumfer ence ofthe end of the penholder,}so that the space below said opening will be'practically sealed apart from the atmosphere 'sfoffarfla's communication is *possible between .said

space and the opening; r in Other objects and advantages will be unatmosphere through said derstood by, reference; to the following specification and'accompanying drawing; in which I have illustrated a pen support'embodying aselectedform of my invention.

- tions.

Figl '5 is 'a plan of the 5m shown injFigi 10 havingits lower end closed as shown at 11, and'prov'ided at its upper end withfian inwardly and downwardly inclined annular seat 12. Theflreceptacle 10 is preferably made of hard rubber or bakelite and is preferably of substantially cylindrical shape. A metallic tubular member 13 fits tightly over a portionof the receptacle 1O and is slotted as shown at 14 -1 1 to provide a plue rality of. upwardly extending finger parts 15-15. i

'In the present instanceQI islotithe upper partiof the metallic tubularmember so as to provide eight such fingers. A shoulder 16 is formed adjacent thelower'ends o f'the fingers in the metallic'tubular member 13 by swaging aportion of the tubular member outwardlyior in" any other suitable "manner. The upper ends of thefingersa're bent at substantially right angles to "provide lateral outwardly projecting portions 17, and the outer end portions of the lateral projections 17 are' jbent upwardly to provide upwardlyextending end portions 18gwh'i'ch arethus laterally offset outwardlyjwithrespe ct tojthe "The tubular meal member '13 is preferably of such metal that the fingers '15 are flexible or resilient so that they may be adjusted inwardly to red'uce the eiiective insidediameterof the tubevat the 'upper' ends'of the fingers. For -efltecting'such adjustment,' I provide an apertured cap member 19 which is provided in itsbottom face with'a spiralgroove 2t)v preferably consist-7 ing of two "substantially complete convolu- The spiral groove 20 isfadaptedto receive. the laterally'ofiset end p0rtions18of the fingersi thef portions 17 of thefingers varying length, as clearly shown Fig? ure 5, to gcauseeach of the said end "p012 'tions 18 to'register with a part of the spiral groove. "I prefer that the portions '17 be so "proportioned that when the fingers extend straight upwardly,- that is tojs'ay, when the j fingers v are in 'their normal position as part of the-tubular member 13, the end portions 18fwill fit in the 'outer 'convolution of. the spiral groove. It willthen be understood that the fingers are in their outermost position of adjustment and the efiective inside diameter of the tubular metal part 13 at the upper ends of the fingers is at its maximum. By rotating the cap 19 counter-clockwise, as shown in Figure 4:, it will be understood that the ends 18 of the fingers will be caused to move radially inwardly so that the efi'ective inside diameter of the tube at the upper ends of the fingers 15 will be accordingly reduced. In Figure 2 of the drawing, the fingers 15 are shown in their outermost position of adjustment wherein they are adapted to support a pen 21 (indicated in broken lines) of relatively large diameter, the pen being supported substantially co-axial with the tubular member 13 and annular seat- 12 on the upper end of the receptacle 10. In Figure 3, the fingers 15 are shown in their innermost position of adjustment wherein they are effective to support a relatively thin pen 22 (shown in broken lines) in position substantially eoaxial with the tubular member 13 and annular seat- 12 of the receptacle 10. It will be understood that the lower ends of both the large pen 21 and small pen 22 will thus be maintained seated on the annular seat 12 with substantially the entire circumference of the lower end of the pen in engagement with the said seat. It will be apparent from the above description and an inspection of the drawing that the fingers 15 are positively adjustable from their outermost position shown in Figure 2 to their innermost position as in Figure 3, and also positively adjustable in the reverse directionrthat is to say, from their innermost or contracted position" to their" outermost 'position. By means of the interlocking connection between the ends18 of the fingers and the cap 19, adjustment of the fingers is accomplished without depending upon the resiliency of the said fingers.

' The sleeve member 23 is rotatably mounted on the metallic tubular part 13 immediately below'the shoulder 16, and the cap 19 is secured to the upper end of the sleeve in any suitable manner; for instance, by means of screw-threading, as shown at 24. The cap and sleeve may be locked against separation by means of a pin 25 which is positioned in an aperture located partly in the depending flange 26 of the cap member and partly in the laterally outwardly-projecting flange 27 of the sleeve member. The pin 25 has preferably a tight fit in the said aperture so that it will not readily be displaced,

. and obviously the pin serves to prevent separation of the cap from the sleeve by preventing the said parts from being relatively rotated. The shoulder 16 engages an internal shoulder 28 provided in the sleeve 23 to limit upward axial movement of the sleeve and cap, and the engagement between the ca ends18 oft-he fingers and bottom of the spiral groove in the cap prevents downward axial movement of the said arts.

The above described ad ustable socket structure may be adjustably mounted on a base 29 of any suitable material through the agency of a ball-and-socket joint 30, or in any other suitable manner to permit the desired extent of adjustment of the socket part relative to the base. The base is preferably of some heavy material, or is counterweighted so that it,will be effective to maintain the pen socket and pen in upwardly-projecting position inspite of any overhanging weight of the pen or socket part. The metallic part 13 is preferably of a non-rusting metal, or of any other metal which is treated with a suitable rust-proofing process, so that ink or moisture from the ink which contacts with such metal will not cause corrosion of the same. By inspection of Figure 2, it will be readily understood that the chamber 31 in the receptacle 10 is sealed apart from the atmosphere by the lower end of the penholder which is seated on the seat 12 and serves to close the upper end of the said receptacle. Hence, my pensupporting socket is particularly adapted for use in connection with fountain pens and pens of the class disclosed in my co-pending application Serial No. 159,680, filed Jan. 7, 1927,for the reason that the pen point and exposed ink-carrying parts are effectively sealed apart from they atmosphere in the said chamber 31, whereby evaporation of the ink is prevented and the pen point kept moist and in condition for immediate use at all times. 7

It may be desirable in some instances to provide means for limiting the extent of rotation of the said sleeve and cap structure independently of the stop which occurs by engagement between one of the finger end pieces'18 and the adjacent end of the spiral groove 20. In Figures. 6 and'7, I have shown one form of such means, which consists of a short lug or shoulder 32 formed in the tubular metal'part 13 instead of the annular shoulder 16, anda lug 33 formed on the inside of the sleeve 23. Itjwill be apparent that the lug 32 will limit upward movement of the sleeve 23 by engagement with the shoulder 28 and that the lug 33 in the sleeve will permit the sleeve to beturned through only one complete rotation (less the length of the lug 32). By this construction, I avoid the possibility of bending or twisting the fingers 15 which sometimes is possible, in the first described construction, by excess turning of the cap and sleeve.
