Application inea July 11, 1924. sei-iai No. 725,360.

it is stated that lan object of the inventionl is to provide a clip which is of simple and strong construction and which may be attached to the cap of a fountain pen or the equivalent, by means which is integral with the clip and provides a strong andvsubstantial connection without appreciably increasing the cost of the clip.

A further object is to provide a clip metal` having portions of itself so shaped and bent4 as to provide tangs adapted to project inwardly ythrough openings of the pen cap, one of said tangsbeing relatively short and being adapted lto hold its adjacent portion of the clip against lateral movement` relative to the cap and another tang being relatively longer and being adapted atoncetoy hold its respective portion yof the clip` and to retain the against lateral movement effective holding first mentioned tang in position. 1

A further'object is .to so design the clip A that a single bendable tang will be suliicient arrangements of parts,

to hold the clip in firm engagement with the cap. A Y

'Other objects and aims of the invention lmore or less specific than those referred to above,will be in' part obvious and inv part -pointed out in the course of the following description of the j elements, f combinations, `rand applications of principles.'constituting the invention, and

the scope of protection contemplated willbe indicated inthe appendedrclaims. i `In the 'accompanying Adrawings which'are to be taken as a part of this specification and in which I shall show vmerely a preferred form of embodiment of the invention: x

" `Referring' to the drawings for-describing in 4detail the structure showny therein,i"thev l reference character L indicates an` ordinary Afountain penV barrel to `which is connected the usual cap` or guard memberfGr, the same being herein shown as being threaded upon U the-barrel as at- 1 in laccordance with the` which 1s formed of a single piece of sheet' and providing a ,shoulder 3 kadapted torest against the shoulder portion `(a). oftheA peny for limiting the threadl movementy oft-the cap,V and therebyv properlyV guarding the pen point portion i single piece `of sheet metal ofA appropriate contour providing whatumay be termedfthe l body portion 6 and 'aspring portion 7, the usual friction ball as Sabeing atthe extreme end of the portion 7. f 'i The body portion 6 against the outer curved and hastwo "tangs' as therewith,

surface of thecap 9 and 10V integral the forwardend ofthe body. These tangs are both bent at approximately k,right angles to the body and are adaptedto over a continued or projecting portion of kthe body 6;, Itis of such sizeA relative'to 5 of the pen, against injury,`

the tang 9 being at ,ornearthel rear end ofthe body*y and the tang 10.b'eing at or near els isshaped to` liei'snugly i the aperture 11 as to have a snug fit in said aperture, and its length is preferably not greater than the thickness of the cap wall.

The tang 10 is of considerably greater length than the tang 9 and its inner end portionras 13 is bent rearwardly at an acute angle, the portion as 14 of said tang which remains at right angles to the body portion 6 of the clip being substantially equal to the thickness of the cap wall or slightly less. This tang is stamped out from the material ofthe body as most clearly illustrated in Figs. 3 and 4 so that it stands aligned with the tang 9. l

In its normal condition as seen inFig. 8,

p this clip vhas its centra-l portion bowed up- Yao wardly with respect to a straight line as 15, extending from the under surface of the ball 8 to the under surface of the rear end of the body 6.V When being applied, however, onto the pen cap, the end of the tang 10 is moved through the aperture 12, the tang 9 is introducedinto the aperture 11 and pressure is exertedv to spring the upwardly bowed portion downwardly into a straightl ened condition so as to bring` the body 6 into ai close Contact with the surface of the cap throughout the extent of said body, as in Fig.V 1, and so as to cause a suitable spring pressure of the lball and of the opposite end of the clip against the cap.

lVhile the clip is held in this position, the tubular part 2 is inserted and, coming into engag'ement with the already bent inner end portion 13 of the tang 10, easily bends said inner portion 13 backwardly andclamps it tightly between the inner surface of the cap and the out-er surface of the tubular relinforcing liner member- -and this locks the clip against return to its normal bowed condition. a i' It is ilnportantpto note in connection with this structure:

1st.That the tang 10 being connected with the normally upwardly bowed central portion of the clip serves to hold the opposite end portions of the clip resiliently against the surface of the cap.

2nd. That the tang 9 on the rear end portion, and fitting snugly into the aperture 11., is made to cooperate with the tang 1() for n holding the clip against possibility of move- `ment in all directions.

d 3rd. u Thatvby shaping the tang 10 with its inner end portion normally inclined to- .ward'sits final locking position the effort required to complete its bending` Ato locking Vposition is materially reduced, and that also a grade of sheet metal suitablyV tinck .for forming the main. portion of the clip will also be usable for formingy 'the ltang and thus render it entirely practical to make said tang .integral with the remainder of theclip.

To further facilitate the bending of the .shoulder 16 at its rear end disposed so that when said tubular part is being inserted into the Cap, said shoulder will engage the portion 13 at a' point-suii'iciently near the inner end of the portion 13 to acquire a desirable amount of leverage against the tang.

4th. That by so shaping the tang 10 that in its normal condition the point of bend, as indicated by the reference numeral 17 in said tang, is slightly less far from the inner surface of the body 6 than the thickness of the cap wall the act of bending the projecting inner end of the tang by engagement of the part 2 will produce a crowding effect upon the interposedlwall portion of the cap and afford a degree of leverage which will operate to force the body 6 into tight engagement with the outer surface of cap.

th. That by striking out the tang 10 from the material of the body 6 and thus leaving an opening 18 longitudinally of the body only relatively thin strips as 19 of the `body are left on opposite sides of said opening, which because of their reduced size are suitably flexible to facilita-te a desirably slight degree of bending of the body particularly during the operation of attaching the .95

clip onto the pen cap, thus making it possible to dispose the portion 13 of the tang 10 normally at a more acute angle than it could otherwise be. This resiliency or flexibility .of the body also lends a desirable added flexibility to the operation of the clip in use, while at the same time always holding the tang 9 in snug engagement with the aperture 11.

Y equalfacility upon pen caps or the like of thin sheet metal construction, the only difference in this case being differences in degree.

As many changes could be made in this construction without departing from ,the scope of the inventionas defined in the following claims, it is intended that all matter contained Vin'the'above description or shown in the accompanying drawings, shall be in-v terpreted as illustrative only and not in a limiting sense. y n f A Having thus described my invention what I claim is new and desire to secure kby Letters Patent is l. A pen lclip comprising, a body portion having the usual spring extension, a pair of tangs provided upon saidA body portionv lfor w at least a portion of itself bent to stand normally at an acute angle to the longitudinal plane of said clip so as thereby to facilitate the further bending of said tang when attaching the clip to the pen cap.

2. A pen clip formed from a single strip of sheet metal having a body portion at one end and a friction ball at the other end, ya tang provided upon said body adapted to enter a suitable opening' in the pen cap, said tang being at the extreme end of saidstrip, and a second tang aligned with the first tang longitudinally of the strip adapted to engage the pen cap to thereby cooperate with the first tang foi retaining the clip firmly attached to the cap, and said second tang comprising, a part struck out from the material of the body portion.

V 3. A pen clip comprising, a body portion having the usual springv extension, a tang provided upon said body portion for use in attaching the body portion to a pen cap, said tang being adapted to extend through a suitable aperture in the pen cap and to be bent over internally of the pen cap, and said tang having at least a portion of itself bent to stand normally at an acute angle to the longitudinal plane of the clip so as to thereby facilitate the further bending of said tang when attaching the clip to the pen cap.

4. A pen clip comprising, a body portion having` the usual spring extension, a tang provided upon said body portion for use in attaching the body portion to a pen cap, said tang being adapted to extend through a suitable aperture in the pen cap and to be bent over internally of the pen cap, said tang having a portion of its length disposed substantially at right angles to the longitudinal plane of the clip and adapted to stand within the aperture of the `pen cap, and said tang having the remainder of its .length bent at an acute angle to the longie.

tudinal plane of the clip adapted to project into the interior of the cap, the angular disposition of said second portion'of the tang serving to facilitate the further bending of the tang when attaching the clip to the pen cap.

l 5L The combination with a cap of the type indicated,V of a clip therefor comprising a body portion having the usual spring extension part, two tangs extending from said body portion into openings provided to receive them inthe wall of the cap, one ofr said tangs being bendalole and being normally projecting into the interior of the cap in a direction away from the body of the clip, together with a linery member forming part of said cap andadapted upon inf sertion into the cap to engage and bend said tang and hold said tang bent into substantial parallelism with the body of the clip.

6. The combination with a cap of the class 4 described, of a clip therefor formed from a single strip of sheet metal having aibodyl portion at one end and a friction ball lat the opposite end, said -clip beingr normally bowed upwardly intermediate its ends, a pair of tangs formed as integralextensions of the bodyportion arranged to lproject into spaced openings of thecap, and one'of said tangs serving t-o hold the clip sprung into straightened condition and to utilize the force thus generated for holding the second tang in engagement within its respective opening.

ln testimony whereof I affix my signature.

CHARLES HARDY.
