C. F. NORLIN May 6, 1952 PEN CLIP Filed May 14, 1949 /Jc /7 /Je ggf/24 Patented May 6, 1952 UNITED STATES PATENT OFFICE PEN CLIP Clarence F. Nonni; Chicago, 111.

Application May 14, 1949, Serial No. 93,370'

Claims.

This invention relates to improvements in retainer clips for fountain pens, mechanical pencils and other instruments usually carried in pockets. Retainer clips now in use largely depend on a spring action in the clip which are either dicult to apply to clothing and cause clothing damage or become upsprung and inelfective. Expensive losses due to clip failures are common. The invention will be described as applied to a pocket pen or the like, although it has wider application.

The present invention has for its particular object the provision of a mechanically actuated clip in the form of a hook lever comprising a clamp that is operable without the use of springs.

Another object is to provide a mechanically actuated clip for both opening the clip for insertion in pockets of clothing, and locking the clip in position.

And a still further object is to provide a clip actuated mechanically by a relative sliding movement of the parts of a compound pen cap.

Other objects and benets will be disclosed in the following descriptions and drawings in which:

Fig. 1 is a side elevation view of a pen employing my safety clip in open position ready to be inserted in a pocket;

Fig. 2 is a front elevation view of the pen shown in Fig. 1;

Fig. 3 is an enlarged transverse medial' section view showing my safety clip in open position;

Fig. 4 is a similar view to Fig. 3 showing the clip in locked position; and

Fig. 5 is a cross section view of the clip as it would appear on the section lines 5-5 of Fig. 4.

Now referring to the drawings, I designate the conventional barrel of a pen by the numeral Iii and my safety clip sleeve by the numeral Il. Now referring to Figs. 3, 4 and 5, the sleeve II. ordinarily made of plastics, has a cap I2 secured to its top as shown. Over the top I2 is a slidable cover cap member I3 which is secured to the cap I2 by a stud bolt I4 secured in position by a nut I5. On the cap I2 is a pair of ears I6 having a pivotl bearing Il mounting a pen clip inthe form of a hook lever I8 providing a clamp to secure the pen to a portion of a wearers pocket. The hook lever I8 has on its forward clamp arm end a downwardly protruding hook I8-h which is designed to coact with a cavity I I-c in the sleeve I I to more securely fasten the hook in a fabric pocket. On the opposite end of the lever I8 is a cam projection Ill-c which coacts with a cam bridge I3-c which extends across an extension I3-e forming a laterally offset portion on the cover cap I3 to house the hook lever I8 as shown. The hook lever I8c extends through an aperture or slot I2a in the cap I2 to coact with the cam bridge l3c as clearly shown in Fig. 3.

When the cover cap I3 is slidably depressed downwardly as shown in Fig. 4, the extension I3-e will contact the cam surface on the hook lever I 8 to force the hook I8-h in close juxtaposition with the cavity II-c. When the cap I3 is slid upwardly as shown in Fig. 3, the bridge I3-c will contact the cam IB-c on the lever I8 to position the hook IS-h upwardly away from the cavity II-c to permit the fabric in the pocket to be easily inserted therebetween. The relation of the parts is more clearly explained by the cross section in Fig. 5 and the coaction of the various parts will be readily understood by consideration of this figure in conjunction with Figs. 3 and 4.

From the foregoing descriptions it will be understood and appreciated that when the slidable cover cap I3 is moved longitudinally outwardly. the hook lever I3 with its hook iii-h is removed from the sleeve II to permit insertion of the clothing between the hook I8-h and the cavity I I-c. When the cover cap I3 is slid downwardly, the extension I3-e on the cam lever I8 will depress the hook I8-h into close contact with the sleeve I I in order to effectively lock the clothing between the lever hook I8-h and the cavity I I-c.

Thus I have provided a safety clip which is mechanically actuated without springs to provide easy access of the fabric pocket within the clip and by reverse movement will be locked securely in position and cannot be removed except by sliding the cover cap I3 upwardly. This is practically a one-handed movement of the cap that can be habitually acquired and thus a secure safety clip entirely mechanically actuated and without the use of springs is provided.

Having thus described my invention, I now claim as new:

l. In a retainer clip for pocket devices, a sleeve, a cap upon said sleeve, a locking lever pivoted at an intermediate point to said cap, said lever having a forward hooked end with a cam surface upon its outer surface extending forward from said pivot point, said cap having a slot through which the rear end of said lever projects, said lever having a cam projection upon its rear end, and a slidable cover cap extending over said cap and a portion of said sleeve, said cover cap having means for engaging and depressing the forward end of said locking lever when said cover cap is moved in a forward direction and means for engaging said projecting cam and elevating the said forward end of said lever when said cover cap is moved in a rearward direction.

2. In a device of the character described, a sleeve member, a thimble-like cap upon one end of said sleeve member, a hook lever clamp pivoted adjacent the said end of said sleeve member, said hook lever clamp having a forwardly extending clamping arm with an outer cam surface and a rearwardly extending arm with an outwardly directed cam and a slidable cover telescoped over said cap and having means for engaging over said clamping arm for depressing the same into clamping relation with a garment when said cover is moved in a forward direction, and. means for engaging said cam on said rearwardly extending arm for elevating said clamping arm.

3. In a device of the character described, a sleeve member, a clamping lever pivotally mounted upon said sleeve member, said lever having a forwardly extending clamping arm adapted for' clamping said sleeve member to a garment and a rearwardly extending arm having a cam and a cover cap slidably mounted with respect to said vsleeve and having means adapted for engaging and depressing said clamping arm when saidr cover cap is moved in one direction and means for engaging said cam for causing an elevation of said clamping arm when said cover cap is moved in the'other direction.

4. In a device of the class described, a sleeve member, a cylindrical support on said sleeve member and extending rearwardly thereof, a clamping lever pivoted adjacent the rear end of said sleeve member, said lever having a forwardly extending clamping arm and a rearwardly extending actuating arm and a slidable cover member mounted upon said support and having means for engaging said clamping arm for depressing said lever when said cover member is moved in a forward direction and means for engaging said actuating arm for elevating said clamping arm when said cover member is moved in a rearward direction.

5. In a retainer clip for pocket pencils, a sleeve member, a cylindrical support upon said sleeve member and extending rearwardly thereof, a clamping lever pivotally mounted intermediate its length and adjacent the rear end of said sleeve member, a cover member slidably mounted upon said support and having a laterally offset portion adapted for encompassing a part of said lever and means associated with said oiset portion for operating said lever.
