PENHOLDER S OCKET FilEd Jan. 29, 1927 Patented May 5, 1931 GUSTAV J'. SENGBUSOH, OF MILWAUKEE, WISCONSIN PENHOLDER SOCKET Application filed January 29, 1927.

This invention relates to pen holder sockets and more particularly to sockets provided for the purpose of holding a writing pen in an upright position so that it is conveniently accessible for use.

@ne of 1Lhe objects of the invention is to provide a socket of the class described which will co-act with a portion cfa suitable pen to forml a substantially air tight container for the pen point so that the writing fluid onvpthe pen pointwill not readily evaporate and leave a deposit of writing fluid material which would t-end to clog the pen and impair its writing qualities.

Another object is to provide means in the socket for facilitating the formation of the air tight chamber as above described, without exercising estreme care in placing the pen in the socket.

Still another object is to provide a socket, such as above described, which will be adjustable so as to accommodate a large percentage of the pens or pen holders in use or on the market, wherefore it will not be necessary to provide a special pen for use therewith.

Other objects are to provide a socket such as above described which may be easily cleaned and which is simple in construction andy maybe manufactured at a relatively low cost. j

Other objects and advantages will be readily understood when the following specification is considered in connection with the accompanying drawing wherein I have illustrated a. selected embodiment of my invention, and in which:

Fig. 1 is a plan. t

Fig. 2 is a sect-ion on the line 2--2 of Fig. 1, and

Fig. 3 is a section on the line 3--3 of 2.

`Referring now to the drawings, the pen socketV comprises a tubular member 12, of hard'rubber, bakelite or other suitable material, provided with a bore of small diameter Serial No. 164,411.

as indicated at 13 at its lower end, and a bore of larger diameter as at 14, at its upper end. A shoulder or seat 15 is thus formed at the meeting point of the two bores and this seat is preferably inclined downwardly towards the axis of the tubular member as illustrated in Fig. 2. The lower end of the member 12 is provided with a portion 16 of reduced diameter, which preferably tapers towards its end, and this reduced portion is adapted to receive a cap 17 thereover. The cap 17 comprises, for instance, a tubular portion 18, snugly fitting over the reduced portion 16 at its upper end, and a closure portion 19 at its lower end.

I prefer to provide the said reduced portion 16 on the tubular member 12 so that the outer surface of the member immediately above the said reduced portion will be flush with the outer surface of the cap member l? for a purpose which will presently appear.

The upper portion of the member 12 is provided with a plurality of fingers 20-20, which are adjustable inwardly towards the axis of the member 12 at their top portions. l prefer to form these fingers by slotting the tubular member as indicated at 21-21, thereby leaving a series of etensions or lingers projecting upwardly from the unslotted portion of the tubular member and integral therewith. The fingers so formed will be relatively thin in cross section, and sufficiently flexible, (the member being of hard rubber or the like) to permit bending or flexing thereof so that the top portions thereof may be adjusted inwardly as above mentioned.

Means for effecting adjustment of the fingers 20-20 and for maintaining the fingers in the desired position of adjustment, comprises a tubular sleeve 22 provided with internal screw threading 23 adapted to engage screw threading 24 on the member 12 adjacent the lower ends of the fingers 20. lEhe sleeve is further provided with an inwardly tapering portion or neck 25 which Lio is adapted to engage the upper cud portions of the fingers 20, so as to force the latter inwardly as the sleeve is rotated and caused to move downwardly by the action of the screw threads Q3 and 24.

A pen such as indicated at 2G may be inserted into the socket until the lower end 2T of the pen engages the shoulder whereby the pen point 28 is prevented fronrengaging the closure 19 of the cap, so as to avoid possible injury to the pen. The lingers 20 are adjustable inwardly, so that they hold the pen substantially coaxial with thertubular member 12. The lower end 9.7 of the pen will thereby be caused to engage the sea-t 15 substan'tially throughout its entire circumference, the downward inclination of the seat 15 also aiding in positioning the pen coaxially with the tubular member 12.

By thus seating the end of the pen on the seat 15, a closed and substantially air tight pocket or chamlr enclosino' the pen point is formed in the lower end or the member 12 and the cap 1T. The airtight chamber thus formed is particularly advantageous and desira le when a fountain pen or other reservoir pen is used in connection with the socket, since evaporation of the stored supply of writing fluid is prevented.

The adjustable finger arrangement above described adapts the socket to use with a large percentage of the pens in daily use and on the market, which pens vary somewhat in cross sectional size, and it is therefore apparent that a special pen need not be provided for use in connection with my soci-ret.

For facilitating insertion of 'the nen into the socket, the upper end of the sleeve is provided with an outwardly flaring or funnellike portion 29.

The socket as above described, may be mounted on a desk by means of a suitable bracket, or a base of any ornamental material or configuration, or both, may be provided.

ln the present instance, l have indicated a base preferably of glass, which bz is provided with a central aperture or receptacle 31. The socket structure ia mounted on the base by means of a cover which rests on the top of the base as indicated at 33. An annular flange 3i dependingl from the cover is provided with a plurality of tapped apertures for receiving` thumb screws 35, extending therethrough, which screws may be screwed through the flange and into engagement with the wall of the receptacle S1, for clamping the cover in place on the base. There a base is provided with a receptacle having a bottom closure, th'-x screws may be adjusted to their proper position and the cover then forced into place in the receptacle.

rlhe cover is provided with an aperture indicated at 36 which is adapted to snugly receive the lower cylindrical portion of the member 1Q, a shoulder 3T being provided on the member for positioning` the latter on the cover. I prefer to provide the socket with its axis at an angle to the plane of the cover 52, and for this purpose l depress a portion of the cover as indicated at 88, and raise a portion as indicated at 39. By thus shaping the cover, l provide a surface portion l() at substantially right angles to the axis of the socket when disposed in the desired position of singularity, which surface is adapted to receive the said aperture 3o and whereby firm mounting of the member in such angular position is facilitated.

rlhe pen may be inserted into the socket without exercising extreme care, since the construction of the socket effects proper alignment of the pen in the socket, and the socket may readily be adjusted to receive various sizes of pens by merely rotating the sleeve Q2 until the desired adjustment of the fiugers Q0 is obtained. The lingers 2O are of course, adjusted so that they do not bind the pen but permit free insertion of withdrawal thereof.

The socket may be cleaned with great facility by merely withdrawing` the entire socket from the aperture 36 in the cover and then separating the cap 17 from the member l2. The joint between the cap and member 12 is preferably frictional, although more positive means may be provided, and the socket is preferably retained in the aperture 36, also by friction.

l am aware that various changes in the form, construction and arrangement of parts may be made without departing from the spirit of the invention, the scope of which should be determined by reference to the following claims which should be construed as broadly as possible, consist-ent with the state of the art.
