11 Claims.

The present invention relates to fountain pens and the like and is an improvement over the construction shown in the patent to David F. Johnson, No. 1,344,897, dated June 29, 1920.

Preferably', fountain pens are provided with a cap for protecting the ypen point with a clip thereon for engaging the pocket of a garnient to facilitate carrying the pen. Frequently, while the may cause considerable damage to a personsclothing. A further objection is that material such as cloth is absorbent and draws all the ink from the pen. Thus, when the pen is to be used,

it is dry and must be refilled.

The present invention aixns to overcome these' difllculties ina simple, practical manner by providing an inexpensive, serviceable, automaticcap locking device for preventing the cap and the body part of the pen from separating accidentally. `An object oi the present invention is to provide a cap locking device for fountain pens vand the like, which can be readily manufactured at a low cost.

Another object ofthe invention is to provide 4a cap locking device having a minimum number 3@ of parts. .1 i

Another object of the invention is to provide a simple cap locking device adapted to be applied to existing types of fountain pens.

Another object of the invention is to provide a serviceable cap locking devicewhich is automatic in operation,

Another object of the invention is to provide a cap locking device which cooperates with the pocket clip of the pen.

A further object of the invention is to provide a cap locking device which enhances the appeart ance of the fountain pen. 4 v

Other and further objects of the invention will be obvious upon an understanding of the illus- 45 trative embodiment about to be described or will `be indicated in the appended claims, and vari- .o us advantages not referred to herein will occur to one skilled in the art upon employment `of the invention in practice.. 50 A preferred embodiment of the invention ha been chosen'for purposes of illustration and de- `tcription -and is shown in th accompanying drawing', wherein Fig. lis an elevational view, partly in section, 55 illustnting a preferred embodiment of the invent 1on Fig, 2 is an enlarged sectional view, partly in section, illustrating thev operation of the preferred embodiment;

Fig. 5 is an elevational view, partly in section, illustrating another embodiment of the invention;

and

Fig. 6 is a fragmentary sectional View, illustrating a further embodiment of the invention. Referring again to the drawing, and moreparticularly to Figs. l to 4, there is shown a fountain pen comprising a barrel 2 having suitable devices therein for filling the pen, and a pen section f3 for mounting a feed bar 5 and a pen point The pen section l preferably comprises an. inner tubular member 'lfhaving a shoulder 9 at one end and a centrally disposed bore for receiving the feed bar 5 and the pen point 6 (Fig. 4). The other end of the inner member 'l may be provided with a nipple portion lll for securing asuitable ink sac Il thereto adapted to supply ink to the pen point 6; v

A sleeve or tubular gripping member l2 provided with threads !3 for connecting the pen section to the barrel is mounted on the inner member l, and a collar or band member l5 is broken away mounted on the inner member between the shoulder 9 and the tubular gripping section I2.'

If desired, the tubular member 'l may be provided Awith screw threads or the like (Fig. 4) so that the collarl and gripping member l2 may be threaded thereon. The collar l5 is provided with suitable ratchet portions or recesses I6, herein shown as four in number, which are adapted to be engaged by a suitable member associated with a pen point protecting cap, about to be described, for `locking the cap tothe pen section. Preferably, the ratchet portions or notches comprise cam shaped recesses Il terminating, at one end, in stop faces or projections I8, and merging or sloping into the outer surface of the collar at I9.

sired number of ratchet portions may be utilized Without sacricing the advantages of the present invention.

An advantage of the .above described pen section is that the inner member may bemade of substantially non-shrinkable material and the outer members, namely, the `ratchet 'collar "l5 and gripping member l2, may be threadedv thereon and shrunk into .engagement therewith-:to provide a compact serviceable structure.` The gripping member I2 may bemade of-material which matches the 'barrel or` may be madefof material having any desired.A color. :If desired,

the' gripping member vl2 may be made of hard rubber. The collar l 5 prferablyis made of material having an attractive color, such as red, so

that attention is directed to the improved lockving device. Materials, such as pyroxylin, are suitable for this purpose, since they can be produced in almost any color. The collar I5 thus enhances the appearance of the pen and may be used as a trade-mark or identification mark.

A suitable pen cap' 20 is provided for covering and protecting the pen point when the pen is not in use. Preferably, the cap matches` the barrel of the pen and is made of the same material-as the barrel. Preferably, pyroxylin is utilized because it can be produced in attractive colors, and is slightly resilient and substantially unbreakable. The cap may have a tubularskirt 2| adapted to be telescoped over the pen section and threads 22 are formed therein, for engaging corresponding threads 2t on the barrel. The pen may be carried conveniently in the pocket of a garment by providing a clip 25 on the cap having a substantially ball-shaped engaging portion 26 at one end thereof and having suitable inturned portions, 2l at the other end for attaching the clip to the cap. Preferably, the clip is pivotally mounted with respect to the cap by extending the portions 2l into a slot or aperture 29 formed in the cap and connecting the portions 21 to a suitable anchor bar 30 by means of a pin 3|. The anchor bar is secured to the cap by a tubular sleeve 32 telescoped into the skirt of the cap. A suitable spring34 is mounted on the pin 3i and its respective ends engage the anchor bar and the clip to hold the clip resiliently in engaging position. While other forms of clips may be utilized, the above described clip is par-- ticularly desirable because it is'adapted to effectively engage materials of any thickness without damaging the material. In addition, the clip is particularly adapted to be used in connection with the cap ionizing device about to be described.

In order to prevent accidental separation of the cap and the barrel, a suitable latch or tongue portion 35 is provided in the skirt oi the cap for engaging the ratchet recesses or notches i6 on the pen section collar l5. Since the material of thev cap is slightly. resilient, it is desirable and advantageous to form the latch integral with or from the skirt of the cap. 'Ihis may be done. conveniently and inexpensively by providing a pair of longitudinal slots 36 in the cap and joining them-at one end by a transversely'extending slot 31 to define the tip of the latch. Preferably, the latch is positioned beneath the clip and is provided at the tip thereof with an outwardly extending member or button 39 adapted to cooperate with the clip. -When the clip engagesK a piece of material, the thickness of the material forces the tongue inwardly. This is further `facilitated by the spring action of the clip which forces the material against the button. Removal of the cap is prevented, since the latch either is engaging one of the recesses IB or,

upon unscrewing of the cap, the latch'will engage a recess.

A featureof the present invention, is that the,

thick material without danger of breaking the latch or forcing it too tightly against the pen section. In this manner, the cap locking device is automatically operated by material of various thicknesses.

A further advantage of the above described cap locking construction is that the latch can be made without material increase in cost. Com' plicated locking attachments, which are expensive, which are attached with great diiiculty, and which mar the appearance of the pen, are eliminated. The button 39 can be readily attached to the latch by cementing it or molding it thereon. If desired, the button may be made of material having a distinctive color, such as red, to attract the purchasers attention to the improved cap locking means.

In Fig. 5, a slightlydiilferent pen cap locking device is shown, wherein ratchet portions or recesses 40 are provided at the lower portion of Lthe gripping section l2. In this manner, a separata collar need not be utilized and the number ofparts and the cost of making the pen section are reduced. The pen cap is provided with a latch 4I extending longitudinally beneath the clip and terminating adjacent to the lower end of the clip and 'a suitable button member 42 is provided on the latch for facilitating inward movement` of the latch to engage the ratchet portions 40 on the pen section.

Another form of pen cap locking device is illustrated in Fig. 6. The cap has a slot` 43 for receiving a latch member 44 mounted on an anchor bar 45 at 46. One end of the latch memu ber is provided with a radially inwardly extending portion 48 for engaging a suitable recess IG on the pen section, while the other end 49 extends beneath a clip 5l for attaching the pen to a pocket or the like. Preferably, the clip is pivotally mounted on the anchor bar at 52 and is provided with tab portions or fingers 50 adapted to lengage and cscillate the upper end 49 of the latch. When the clip engages a piece of material and is oscillated with respect 'to the anchor/ bar, the end 49 of the latch is moved radially outwardly, whereby the end 48 cap 20 is screwed on the barrel. l'Ihe clip is then 'attached to the vmateriel of the pocket. As the material isv inserted between the clip and the button on the. latch member (Figs. 1 to 5), the latch member is forced radially inwardly so that the inner end of the latch engages the ratchet l collar. The cap cannot be unscrewed because the latch extends into`one. of the notches on vthe colv lar.

When the pen is removed from the pocket, the latch, due to its resiliency, moves out of engagement with the ratchet collar and the cap can be readily unscrewed. In this manner, the locking devices are entirely automatic in operation. The device shown in Fig. 6 is operated` by the clip when itis moved away from the skirt of the Cap.

It will be seen that the present invention provides asimple cap locking construction madevfrom parts which can be readily manufactured. The locking device is automatic in operation and permits the cap to be removed and replaced in minimum time and with minimum effort. When the pen is clipped to a pocket, the locking device and the clip cooperate to lock the cap securely on the barrel of the pen. While being carried in this manner, the cap and barrel cannot come ment.

apart.-v 'I'he pen cannot leak and stain the gar- In addition, the locking means of the present invention enhance the appearance of the pen and can readily be applied to any type of pen without materially increasing the cost thereof. The locking device is rugged in construction and is fully capable of withstanding any rough usage to which it may be-subjected.

As various changes may be made in the form, construction and arrangement of parts without departing from the spirit and scope of the invention and without sacrificing its advantages, it'is to be understood that all matter herein'is to be interpreted as illustrative and not in a limiting sense. l
