21 Claims.

This invention relates to penholders and more particularly to pen gripping and releasing means for various types of penholders, including fountain pens.

5 The problem of providing a simple and easily operated gripping and releasing means for a penholder has occupied the attention of the art for many years. Some of the prior art mechanisms are difiicult to operate and therefore do not appeal 1 to the impatient public. Others are expensive in construction and lack the basic mechanical simplicity which makes for ruggedness and reduces the chance of defective operation.

The invention herein disclosed provides an efficient and simple pen gripping and releasing means. The construction of penholders embodying this invention is simple and inexpensive; the working parts may be molded from any of the suitable synthetic materials now available. Another advantage of this invention is the positive character of its operation. A partial turn of the operating sleeve releases the grip on the pen point; a partial turn of the sleeve in the reverse direction firmly grips the pen point for use, An-

25 other. advantage is the absence of parts which might become jammed from the accumulation of dried ink. Still further objects and advantages of this invention will become apparent from the following detailed description of the illustrative 30' embodiments of the invention shown in the accompanying drawings.

Fig. I is a partial side View of a penholder embodying this invention, shown partially in section to reveal the component parts thereof.

Fig. II is a transverse section of the device shown in Fig. I, taken similarly to that of Fig. III, but showing the relation betwen outer and inner gripping elements in the released position before the pen has been gripped thereby.

Fig. III is a transverse section taken as indicated by lines IIIIII in Fig. I.

Fig. IV is a transverse section taken as indicated by lines IVIV in Fig. I, showing the fit of the handle and shaft-like grippingelement.

Fig. V is a perspective showing of the shaft-like inner gripping element.

Fig. VI is a perspective showing of the sleevelike outer gripping element, partially broken away to show the interior thereof.

Fig. VII is a partial side View of a penholder embodying a modification of this invention, being partially in section to show the working parts thereof.

' Fig. VIII is a transverse section taken about 55 the lines VIII-VIII of Fig. VII.

Fig. IX is a transverse section of a modified form of this invention taken as indicated by the lines IXIX of Fig. X.

Fig. X is a partial side view of the modification of this invention illustrated in Fig. IX, being par- 5 tially in section to show the working parts thereof.

Fig. XI is a transverse section taken about the lines XI-XI of Fig. X.

Fig. XII is a partial side view of a penholder embodying the form of the invention shown m Figs, I to V1 in which an additional wedge is provided to positively release a pen point from the holder.

Fig. XIII shows a transverse section taken about the lines XIII-XIII of Fig. 2m and shows the clamping wedge in operation clamping a pen point in position and also the releasing wedge which is not in operation.

Fig. XIV shows a transverse section taken about t the lines XIV-XIV of Fig. IQI but shows the .releasing wedge in operation and the clamping wedge not in operation.

Fig. XV is a perspective view of the inner gripping element as adapted to include a cam surface to cooperate with the releasing wedge.

Fig. XVI is a perspective View, partially broken away, of the outer or sleeve-like gripping element as adapted to include the releasing wedge.

Before taking up the detailed description of the invention, it may be helpful to point outthat the subject matter of Figs. I to VI is the same as that in Figs. XII to XVI except that the latter includes a duplication of the wedge and cooperating cam to spread the two gripping elemerits in releasing a clamped pen point. The description of this invention in its differentforms proceeds more easily when uncomplicated with the two wedges and cam surface in each form. The description of Figs. I to VI'may therefore be read as an introduction to the more complicated 40 and perhaps more practical showing of Figs. .XII to XVI which are similarly numbered. The other figures are directed to modified forms of the invention.

In describing the preferred embodiment of this invention and the modifications thereof illustrated in the drawings, a specific terminology will be resorted to forthe sake of clarity. However, it is to be understood that there is no intention of being limited to the specific terms'sc se-, lected, but on the contrary each specific term is intended to include all technical equivalents which operate in a similar manner "to accomplish a similar purpose.

In Fig. Ithere is shown the gripping end of a penholder, partially in section to show the relation of the component parts thereof. This penholder may be made from any suitable material known to the art and particularly good results have been obtained by molding the parts from synthetic materials which are receiving such wide use today. A small amount of flexibility is desirable both for the gripping operation and to avoid general breakage. Of course, the parts could be machined rather than molded, but from a manufacturing point of view it is far cheaper toproduce the few simple parts necessary for this invention by the use of molds.

This improved penholder comprises generally a handle Ill, an inner gripping element ll mounted in the end thereof, an outer gripping element or sleeve 12, revolvably mounted on said inner gripping element H, a wedging projection 53 formed on the inner surface of the outer gripping element or sleeve l2, a feed bar l4 mounted on the end of the inner grip-ping element. I! and a conventional pen point [5 gripped in place between the gripping elements H and I2.

The handle I9 is formed with an opening !8 in the end thereof, the shape of the opening it being generally cylindrical with fiat side areas 59. The cross sectional shape of the inner gripping element I I conforms to the shape of the flat sided cylindrical form of the opening it in the handle Ill. The inner gripping element II fits snugly into the handle l; and because of the flat areas I9 which correspond'to similar fiat areas iii on the inner gripping element I I, all relative rotary movement between these parts is avoided.

The sleeve I2 is revolvably mounted on the inher gripping element H which is journalled at i l to move easily in a bearing surface formed on the inside of the sleeve l2 at 25. The bearing surface 25 terminates in a shoulder 26 at the central portion of the sleeve 12 where the diameter of the sleeve 12 increases over its diameter at the bearingsurface 25. A shoulder 21 is formed on the inner gripping element H to correspond and cooperate with the shoulder 26 on the sleeve [2. The cooperation of the shoulders 26 and 2? confine the sleeve l2 in place with the inner end of the sleevelZ in sliding contact with a corresponding surface formed on the inner end of the handle I0 and around the projecting inner gripping element H. A short counter bore 28 in the inner end of the sleeve l2 provides a circular space to catch any ink which might inadvertently work up through the gripping parts. This space formed by the counter bore 28 may be filled with a graphited or parafiined packing or any suitable packing material to resist the flow of ink therepast. The flat surfaces 29 and 29a (see Fig. V) provided where the feed bar Id merges with the inner gripping element 8 l are intended to further reduce the possibility of ink working up through the moving parts of the gripping means.-

The bearing surface 25 merges at the shoulder 26 into what may be conveniently termed a gripping surface 30, although only a portion of this surface 30 actually grips the pen IS. The wedging projection I3 is formed on this gripping surface 3!] and is in the shape of a narrow longitudinally extending ridge for convenience in manufacture. Clearance between the wedging projection l3 and the cam surface 32 is allowed so that all gripping pressure between these parts is applied opposite the pen seat 40. The inner gripping element ll is cut away to accommodate the wedging projection l3 and this cut-away portion of the inner gripping element 1 l is developed into a cam surface 32, eccentrically formed with a low area which provides sufficient space between the sleeve 12 and the inner gripping element H to accommodate the wedging projection l3 therebetween without wedging action. The high area of the eccentrically developed cam surface 32 is designed for wedging cooperation with the wedging projection 13 and a slightly flat seat ing surface 34 is provided on the cam surface 32 at a predetermined point. This seating surface (i l receives the wedging projection I3 in its extreme wedging position with the pen l gripped in place for writing. As wear occurs, this seat 3% will advance on the high area of the cam surface in the direction of the tightening rotation. By rotation of the sleeve l2 in the direction of the arrow in Fig. II, the wedging projection 13 is brought into operative contact with the cam surface 32.

Diametrically opposite the seating surface 34, a recessed pen seat M1 is formed with a delineating abutment M shaped to fit the type of pen to be accommodated. It is obvious that the particular form of this detail is within the compass of the skilled artisan as are other modifications which might be made in the above described parts without departing from the spirit of the invention. The recessed seat could be formed in the sleeve l2 instead of in the inner gripping element H as is shown in Fig. VIII. The cam surface 32 is positioned completely within the sleeve I2, being formed a short distance back from the end of the inner gripping element H. The exposed end of the inner gripping element i i opposite the pen seat ili is thus cylindrical in form, the cam action being hidden from View by a wall 43 which limits the extension of the wedging projection l3 to a point short of the end of the sleeve I2.

The feed bar M is formed on the outer end of the inner gripping element 8 l and has transverse reservoir slots 15 and longitudinal reservoir slots 56 formed therein. These slots 45 and 46 function by retaining an ink supply which is gradually fed to the pen 15 in the usual manner. Obviously the feed bar M is open to modification and may even be omitted in some forms of this invention. The feed bar It is upwardly inclined in order to provide a convergence between the upper surface of the feed bar [4 and the lower surface of the pen point i5. This tends to pre vent capillary advance of ink up from the pen point end and into the working parts of the gripping means. The narrowing of the space between the pen point [5 and the feed bar M toward the pen point end encourages a downward capillary action.

While the operation of the above described device is perhaps clear from what has been said, a short description of a normal cycle of operation is appropriate. It is convenient to start with the penholder in the condition shown in Fig. I with the pen l5 gripped for writing. To release the pen !5, the handle Ill is held while the sleeve I2 is rotated to the position shown in Fig, II. The pen i5 is now so loosely seated that it will fall out of the penholder under its own weight. If there should be a heavy incrustation of dried ink, a slight pressure will immediately dislodge the pen l5. There being no metal parts, the penholder may now be cleaned with water. A new pen it may then be substituted in the recessed.

seat at and the sleeve 12 rotated in the direction of the arrow in Fig. II to the gripping positions with the wedging projection l3 seated on the slightly flat seating surface 34.

The penholder may be completely disassembled to facilitate cleaning by removing the inner gripping element from the handle which is held together only by closely fitting joint.

"me above described invention is susceptible of a number of modifications and some of these are described hereinafter. One such modification is shown in Figs. VII and VIII. Fig. VII shows an eccentrically developed cam surface 50 formed in a sleeve 5| and a wedging element 52 formed on 7 an inner gripping element 53, thus reversing the positioning of these elements from that in the preferred embodiment described above. The wedging element 52 is also shortened longitudinally. In this modification the inner gripping element 53 is formed integrally with a pen handle 54. A journal 51 of slightly larger diameter than. the rest of the inner gripping element 53 is formed on the inner gripping element 53 adjacent the handle 54. A shoulder 58 is formed on the handle where it merges with the journal 51. This journal 51 receives the sleeve 5| with a fit which keepsthe sleeve 5| in place butallows rotation and removal. A feed bar |4a is formed integrally with the inner gripping element 53 and has already been described above. A pen I50. is shown seated in a recessed seat 40a formed in sleeve 5| and gripped in place as in the preferred embodiment. The operation of this modification is substantially the same as the preferred. embodiment and will be understood from the'above description of an operative cycle of the preferred embodiment. This form of invention is disassembled by simply pulling the sleeve 5| from its position on the journal 51. Of course, when the pen I5 is gripped in place this wedging action also holds the sleeve 5| against any looseness which it may develop in its fitting on the journal 51 as the penholder is used.

Another modification of this invention is illustrated in Figs. IX, X and XI. This modification includes a locking device for keeping a pen point in place in the penholder until properly released by rotation of the operating sleeve. This will help prevent the theft of pen points from penholders used in public places. This form of the inventioncomprises a handle 60 having formed integral therewith an inner gripping element 6|. an operating sleeve 62 revolvably mounted on a journal 63 formed on said inner gripping element 6|, a wedging projection 64 formed in said sleeve 62 and a locking pin 65 extending through said inner gripping element 6|- and through a hole provided in pen point |5b seated in recessed seat 40?) formed in said inner gripping element 6|.

The handle 66 is provided with a shoulder 66 where it merges with the inner gripping element 6|, the shoulder 66 is adjacent to the journal 63 and provides an abutting edge for the inner end of the sleeve 62 which fits in place over the journal63. The outer portion of the inner gripping element 6| is of slightly less diameter than the H journal 63. Because the sleeve 62 is formed with a uniform internal diameter of a size to fit the journal 63, a slightspace is provided between the sleeve 62 and the outer portion of the inner gripping element 6| which permits a limited amount of flexible movement of the inner gripping element 6| within the sleeve 62.

i The wedging projection 64 formed on the inner surface of the sleeve 62 is given a convex shape.

This wedgingprojection 64 contacts operatively' cave surface -!0. While this cam' surface'is not eccentrically developed, the operation of the wedging projection and the cam surface will be clear from what has been said above and need not be repeated here. The flat surfaces 69 proprovide the low portions; and the surface 10 provides the high portion of the cam surface. In this form of the invention a turning movement of the operating sleeve 62 in either direc-. tion will release the-pen |5b.

The locking pin 65 extends diametrically through the opening formed in the inner gripping element 6| with one end of the opening at the central portion of the recessed pen seat 401) and the other end of the opening at the concave surface 76. The locking pin 65 has a cylindrical head 12 with aconvex top to operatively contact wedging projection 64. The head 12 is of greater diameter than the remainder of the locking pin 65 and the opening through the inner gripping element 6| to accommodate the pin 65 is provided with a countersunk portion 13 to receive the head 12. This countersunk portion 13 of the locking pin opening terminates in a shoulder and a coil spring 54 is positioned on this shoulder underneath the head 12. The pin 65 is long enough to extend through a hole formed in pen point |5b when the head 12 is seated on the wedging projection 64. In this position, however, the pin 65 must be short enough to be in easy sliding contact or have no contact at all with thesleeve 62.

This modification is also provided with a spring retaining clip 16 which is riveted to the sleeve 62 by rivet TI. The movable end of this clip 16 is rounded and rides in groove 15 formed in the journal 63. A short longitudinally extending recess 18 is formed in sleeve 62 to allow for the movement of the-clip 16 as the sleeve 62 is removed from the journal 63.

The operation of this form of the invention is substantially the same as the above described embodiments except for the locking feature. As the sleeve 62 is rotated in order to' release the pin 65, the head 12 of the locking pin 65 slides over and away from the wedging projection 64, and under themotivation of the spring 14, is urged into contact with'the inner surface of the sleeve 62 adjacent to the wedging projection 64. This causes the pin 65 to withdraw from the hole in the pen |5b allowing the pen I 5b to be removedas in the above described embodiments of this invention. Of course, the wedging projection 64 must be sufficiently high to cause the pin 65 to fully withdraw from the hole in the pen |5b when the pin 65 is in the unlocked position. When a new pen |5b is inserted in the penholder and the sleeve 62 is rotated toward the locked position, the head 12 rides up on the wedging projection 64 and the pin 65 is advanced through the hole formed in the pen |5b" to receive the pin 65.

In Figs. XII to XVI, the invention embodied in Figs. I to VI is shown with an additional wedging element 86 and cooperating cam surface 8| to provide a positive releasing 'action. This releasing wedge 80 and cam 8| are so positioned with relation to the gripping wedge .l3 and cam surface 32 that the releasing wedge 86 begins to operate as the gripping wedge |3 approaches its inoperative position and vice versa. This is shown clearly in Figs. XIlI and XIV. In Figs. XHI, the penpoint I5 is gripped in position in the penholdler with the releasing wedge inoperative.

In Fig. XIV, the gripping wedge |3 hasv been turned to its inoperative position and the releasing wedge 80 is fully operative in positively spreading thetwo gripping elements I! and I2 to allow the pen point I to fall out of the penholder. The description relating to Figs. I to VI fully applies to Figs. XII to XVI and need not be repeated. The operation of the releasing wedge 89 and its cam surface 8! will be readily understood from the above description of the operation of the gripping wedge I3 and its associated cam surface 32. The same numerals are used to identify similar parts and of course the added releasing wedge 80 and cam surface 8| are given new numbers.

It will be seen that the above invention provides a penholder whichaffirmatively grips and easily releases the pen point by the simple turning of an operating sleeve. The parts of this penholder are adapted to manufacture by mold- 7 ing from synthetic materials and the form of parts of the penholder is sufficiently simple that the chance of breakages and defects of operation is greatly reduced.

The simplicity of mechanical operation provides a ruggedness in the component parts which is not present in more complex mechanisms such as those including pivotally operating levers and the like which the prior art now discloses.
