TEFFT, OF JANESVILLE, WISCONSIN, ASSIGNOR TO THE PARKER PEN COMPANY, F JANESVILLE, WISCONSIN, A CORPORATION 0F WISCONSIN DESK SET STRUCTURE appucation mea February 1, 1932. seran No. 590,177.

My invention relates to desk sets of that character including a base adapted to rest Hat-wise upon a desk, or a like surface, for supporting a Writing instrument, (such as a fountain pen or pencil) in position for ready use, and it has to do more particularly with novel base structure therefor.

The primary object of my invention is to provide a simple and inexpensive structure l0 of the foregoing character adapted for ready and quick conversion of an ordinary pockettype fountain pen unit into a desk set unitand vice versa, wherefor a single fountain pen unit may efficiently serve for both pocket and desk set purposes.

A further object is to provide a base structure to which the ordinary cap of a fountain pen may be releasably attached for supporting the fountain pen in an upright condition for desk set use, which cap serves the purpose of the bowl or receptacle usually employed in devices of this character.

Additional objects are to provide a Vsocalled bowl-less or receptacle-less desk set;

to provide support means cooperative with the cap-carried clip of the fountain pen for y supporting the cap in position to receive and hold the fountain pen in upright condition with its writing point downward; to provide an arrangement of the foregoing character which does not require the manipulation of any fastening means to secure the parts in operative position or to disassemble the same;

and to provide a structure, embodying but few parts which may be inexpensively manufactured and assembled.

Other objects and advantages will `become apparent as this description progresses and by reference to the drawing wherein,

' Figure l is a top plan view of an assembled desk set structure embodying my invention;

Fig. 2 is asection, partially in elevation, through the structure shown in Fig. l, and illustrating different approximate positions which the pen cap may assume in applying the same to the base structure;

F ig. 3 is a section taken substantially at right angles to Fig. 2, the pen and cap assembly being omitted; and

Fig. a is a plan view of the structure shown in Fig. 3.

It will be understood that while my invention is adapted particularly to fountain pen desk set structure, the assembled unit may also well serve the purpose of supporting a pencil or other writing instrument.

Referring particularly to the forni of structure shown in the drawing, it comprises a onepiece, circular base l0 which may be die-cast or formed in any other suitable manner from an inexpensive material. The base shown in the drawing is of a. plural diameter character but it is obvious that this shape is dependent merely upon choice and the base may take any desired shape inclusive of the features hereinafter pointed out. For sake of lightness in weight, the base may be cored out7 providing a bottom opening ll, which opening is covered by a piece of felt, or othersuitable material, l2, which is adapted to prevent marring of the surface upon which the base may rest.

In desk set structures it is customary to include a receivingfreceptacle which is attached to the base for receiving and supporting the writing instrument. According to -my invention this receptacle is eliminated and the ordinary detachable cap of the fountain pen is employed for this purpose. This feature involves a problem of attaching and supporting the cap upon the base and I accomplish this cooperatively with the cap-carried clip of the fountain pen as follows: The fountain pen illustrated is of a Parker type and the top face of the 4base 10 is provided with a socket or pocket 13 of general V-shape having a wall contour approximating the contour of the closed end of the fountain pen cap 14. More particularly, the V-shaped seat is provided with' a flat-surface, particircular bottom 13a disposed at an angle with respect to the axis of the base against which the fiat end 14a of the pen cap is adapted to seat; and the side wall surface 13b thereof is of semi-annular form bulging slightly at 13c so as to receive and unifprmly fit to the end portion of the cap laadja'cent its flat end 14a. The seat surface 18d extends away from the surface 13 at approximately right angles so that with the end` 14a of the cap resting @All 1 leg may be soldered in place.

against the surface 13a the cap is supported approximately in the position shown 1n F1gures 1 and 2. lt will be understood, however, that the aneular relationship of the seat surfaces 13a andD 13", as Well as the relative shapes ot these suriaces, may be varied to suit the particular requirements of the user inthe use of his `.tountain pen with the base 10. For example, the end portions of various caps may vary in shape and the shape of the seat suri'aces may be accordingly varied With` out departing from my invention.

'lo secure the cap 14 upon the base 10, I preferably employ the following:

The base, on opposite sides of the seat 13, is provided with openings land 16, both ot which entend :troni the top face of the base into the bottom opening 11. These openings and 16, for use with the cap shown in the drawing, are located, preferably, at the approximate position indicated in Figs. 3 and l to one side of the apex ot the il-shaped socket 13, Wherefore in the use o1 the structure new to be described, the cap 14 is held firmly under tension in the position shown in Fig. 2, and Without looseness in the assembly employed. This securement of the cap is aceomplished by the use ot an inverted lll-shaped spring member 17, the legs 17a and 1'2" ot which, respectively, are mounted in the base openings 15 and 16. Both of these legs, preferably, entend through the base into the bottom opening 1l and the end of the le@ 1 7 is turned over against the top vvall or the opening 11, preventing withdrawal of the spring l?. The spring leg 17EL is, preferably, secured (in any desired manner) against downward movement in its opening 15. rllhis securement may be effected by interlocking the turned over end 17 ot this leg with the base in some suitable manner, or some suitable adhesive material or the like may be ap `plied to the spring leg 17 in its application to the base to etlect this result, or this spring The other springleg 17 is free in its opening 16 to move up and down. 'llhe base ot the spring l? bridges the socket 13 to one side of the apex of the latter and it tapers inwardly from its legs, providing a. depressed or bowed central portion adapted to receive and hold the fountain pen cap-clip 18 in a centered position and against lateral displacement. The base olf base portion is such as to guide the pen cap into and hold it in substantially the position shown in Figs. 1 and 2.

l'n the use of the base structure, the owner et the ordinary pocket "fountain pen removes the cap lstot the same and turns it to substan-l tially the dotted line position indicated at in 2. The cap is then moved in such a Way as to pass the base of the spring member 17 between the end 18 of the clip and the side Wall et the cap to substantially the position it shown in Fig. 2 wherein the closed 2 Leeaisi end of the clip and the spring 17 are in abutting relation. In this position the spring 17 and clip serve as a bearing unit about which the cap 14 is rotated toward the full line position of Fig. 2. In this rotation the cap and base assume an intermediate position indicated by the dotted line position B of Fig. 2 wherein the end edge 14n of the cap opposite the clip-spring bearing engages the top of the base approximately at the outer edge 13d of the sen1i-annular scat surface 13b. Upon further rotary movement ot the cap from the position B of F ig. 2, the clip-spring side of the cap is slightly raised due to the leverage action of the parts, raising the spring 17 and placing it under tension. This action permits the end edge 14 of the cap, which was originally seated at 13d to slip into the socket 13 and ride inwardly along the inclined Wall 13b thereof until the flat end of the. cap rests against the iiat seat 13a. It will be noted that during the foregoing movement the spring 17 is first raised and then lowered, Whereore the spring l? constitutes a reciprocable axis upon which the cap rotates. lt Will be further noted that the axis of rotation of these parts is normally farther avvay from the end edge 1li of the cap than from any part of the surface. of socket 13. lt will, therefore, be seen that during the cap movement, and While the cap is in its mountledposition, the spring 17' is under tension and the relative centers and positions et the parts above described are such that the cap Will be held in this position until pressure is applied to move the cap in the opposite direction and toward the position A of Fig. 2. It

Will also be appreciated that the relationship just described may be varied to suit conditions of use as, for example, Where the position of the clip With respect to the closed end of the cap varies,all of which may be done Without de arting from my invention.

ln the toregoing the objects and advantages of my invention hereinabove more particularly stated will be obvious; and it is to be understood that While have shown only one form ot structure embodying my invention, other changes in details and arrangements of parts may be made Without departing from the scope and spirit of my invention as defined by the claims which follow.
