June 29, 1965 w. SHEA 4 DISPLAY CAP BALL-POINT PEN Filed June 21, 1963 FIG INVENTOR." WARREN SHEA BDV M6 ATTO-RN EY 3,191,329 j DISPLAYCAP BALL-POINT PEN i Warren Shea, Jersey City, NJ assignorto Radiant Pen Corp., Kenilworth, NJ. Filed June 21, 1963, Ser. No. 289,534 4 Claims. (Cl. 1 -334) 'I'his invention relates to a ball-point pen, and more particularly to a pen provided with an internal arrange- -ment for displaying printed or colored materials.
Display pens are desirable for carrying messages vor for ornamental reasons. Printing on the outside of the pen is subject to constant wear which eventually causes illegibility of theprinting or ornamentation.
If the display `material is simply inserted under the barrel, it is free to move, and sometimes is lost to view.
Where .a pocket was provided, a split barrel or grooved sleeve generally was used which were neither dust proof nor easy to manufacture.
In Patents Nos. 3,077,691l and 3,077,692, I provided a pen barrel with an anchored inner sleeve upon which the printed message or decoration was placed. Alternatively a separate display sheet was wrapped upon the sleeve before insertion into the barrel.
f I have`found however that during use, when displayed in the barrel of the pen, the advertising material is hidden by the ngers.
' Accordingly, it is 'an object ofthe pr'esentinvention -to provide a display pen wherein the display is exposed to View even when the pen is in use. Thismay be in addition to the display space, if provided, in the barrel.
The foregoing object of the invention can be accomplished by placing the display within the cap of the pen.
H owever, placing an inner `sleeve into the cap as Vwas `,clone in the barrel, requires an accommodation for the 4complicated shapes-on the inner surface ofthe `cap in most types of^projects-and retract mechanisms, The
`principal object of the invention was solved by providing -an auxiliary cap, and'- forming a compartment between the auxiliary cap and the cap itself for the display results obtained as will be apparent from the pen described in the following specication, particularly pointed out in the claims, and illustrated in the accompanying drawing in which:
FIG. l is front elevation of the display cap ball-point pen incorporating the invention.
FIG. 2 is a longitudinally sectioned view of the same.
FIG. 3 is an exploded view of the pen showing the various parts. V
FIG. 4 is a modification of the auxiliary cap anchoring structure.
FIG. 5 is still another modication of the same.
Referring more in detail to the drawing, reference numeral designates the display cap of the ball-point pen, which is ordinarily threaded .at 11 to attach it tothe barrel.
The barrel 12 contains an internal bore 13 for the spring 14 seated on the ledge 16, the centrally positioned writing cartridge 18 having the writing point 20, and ears 22 for compressing the spring against the ledge 16. The bar-rel is externally threaded at 23 to engage threads 11 of the cap.
United States Patent() npartrnent need be'about .004 inch in thickness.
ice l i 2 The Vcap 10 contains a push plunger project-retract mechanism which may comprise the push plunger 24 terminating in a circular set of teeth 26; an inner rotat- .able shaft 28 seated within the recess 30 of the plunger 24; and a set of -teeth 32 mounted on the shaft 28 and engaging the teeth 26. The teeth 32 extend slightly beyond teeth 26 to engage projecting teeth 34 moulded on the inside surface of the cap. Between the teeth 34 .of the cap, grooves 36 are provided to permit teeth 32 to slide therein when moved into proper position by the -push plunger 24.4 The grooves 33 between teeth 32 on shaft 28, and grooves 27 betweenY teeth 26 on plunger `24, permit teeth 32 and 26 to be accommodated in grooves 36. Thus the shaft 28 is rotated by the plunger teeth tosuccessively cause teeth 32 to engage teeth 34 and remain in cartridge projecting position, or be projected past teeth 34 and when rotated by teeth 26 to fall into the grooves 36 representing the retracted posi- .tion of the cartridge. The teeth 26 are maintained in `grooves 36 keeping the plunger 24 from rotating. A
recess 38 is provided centrally of the shaft 28 to seat the cartridge end when the parts are assembled.
The cap 16 of the invention comprises an auxiliary cap 40, and a base cap 41. The auxiliary cap is required to be made of transparent material, while the base cap Amay-be opaque to permit the material if printed thereon to be easily visible. The display material may be placed on a 'separate sheet, not shown, and positioned in the compartment 42 formed between the caps. The com- If a press t is attempted, the printing appears distorted. A
j Openings 43 and 44 are formed at the top and bottom ,respectively of the auxiliarycap. About the lower opening44, a peripheral recess 46 is provided for seating a 'flanged ring 48. The base cap tightly tits the auxiliary 'cap at the cartridge end, to seal the compartment.
At the. top ,and bottom of the base cap, opening 49 and 51 respectively are formed. A tubular rivet 50 may be positioned between the auxiliary and base caps, and inopenings 43 and 49thereof to secure the caps permanently together, asis shown in FIG. 2.- The tubular rivet constitutes an anchoring means for locking the caps securely. in position. The lower edge 47 of the base cap .41 extends slightly beyond the corresponding edge 45I of the auxiliary cap .40. I have found that this "provides a supplementary seal with the ring 4S.
` The base cap 41a maybe modiiied as is shown in ing 49a to fit in the opening 43 of the auxiliary cap 40. This mayebe used if a removable grip type of clip is contemplated for the pen.
A permanent type of pen clip 52 having an opening 54 in a transversely extending plate 56, may be interposed between the rivet 50 and the auxiliary cap 40, or under the bead 50a of the auxiliary cap 41a, to support the pen to a coat or vest pocket.
The clip 52a may be modified, as is shown in FIG. 5, by forming a downwardly extending tubular neck 58 in the plate 56a, which can be stacked to form a rivet head, securing the auxiliary and base caps together.
The opening 60 of the rivet 50, the opening 49a in the beaded base cap 41a, and the opening 60a of the tubular neck 58 of clip 52a, permit the push plunger 24 to extend therethrough for manipulation by the thumb for project or retract operation.
When the cap parts are assembled, the ring 48 which may be metal is positioned over the ends of the assembled caps, and seated in the recess 46 of the auxiliary cap to provide a cover for the lower junction of the auxiliary and base caps and to help seal the two caps. The clip is secured in the same operation that connects the eyelet. The project-retract mechanism parts are then -fortable shape.
inserted, the spring and cartridge seated in the barrel and the unitary cap structure with the project-retract mechanism threaded thereto.
A shoulder `may be formed peripherally on the barrel to permit the cap to fit smoothly on the outer surface of the barrel, as is shown in FIG. l.
The structure of auxiliary and base caps with the pen clip forms a unitary 4assembly with the printed or decorative material. The cartridge may be replaced without disturbing the cap parts.
If the permanent rivet structure is employed, the printed or decorative material may be sealed in the cap for the life of the pen. The caps are then more or less tamperproof.
The pen clip may be employed for sealing the parts Ypermanently together. This is accomplished without drilling holes through the side wall of the cap, as is conventionally done.
The printed or decorative material may be viewed without obstruction even when in use. The printed and advertising material is contained in a sealed compartment free of dust and moisture.
The barrel of the pen is gradually tapered near thev writing point to provide .a streamlined and more corn- The tapering, however, diminishes the level area available for display purposes, a disadvantage not present if the display area is provided in the cap.
By lengthening the cap structure to a greater degree than is found in present pens, extra `space may be provided for advertising display, insuring maximum display For example if the length of the cap is greater than the length of the barrel, more visible display area is obtained than is otherwise possible.
In addition, the diameter of the inner barrel is restricted to pass through the threaded neck portion of the outer barrel. This restriction need not be present when the display is provided in the cap. A larger diameter cap, with additional display space, may thus be obtained.
The form of the parts and their assembly lend themselves to high speed, economical production.
I have thus described my invention, but I desire it kunderstood that it is not'conned to the particular form or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention, and therefore I claim broadly the right to employ all equivalent instrucmentalities coming within the scope of the appended claim, and by means of which objects of my invention are obtained and new results accomplished as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to obtain these objects and accomplish these results.
