DECORATIVE BAR PIN Joseph I. Levyn, Brooklyn, N. Y., assignor to Jilko Service Products, New York, N. Y., a copartnership Application June 19, 1944, Serial No. 540,992

9 Claims.

1 My present invention relates to bar pins for personal wear, such as service bars employed to display campaign ribbons and the like, and is directed more particularly to an improved article of the type covered in my copending application Ser. No. 535,836, filed May 16, 1944.

The construction disclosed in my prior application involves readily assembleable cooperating plate members confining the ends of ribbons or other insignia between them whereby the ribbons are held in a taut, smooth condition. The construction, although well adapted for its intended purposes, requires a complete assembly for each combination of ribbons. The present invention has for its principal object the provision of a bar pin of the type referred to, comprising individual pro-assembled, ribbon-carrying elements for mounting on a supporting or backing member. The construction contemplates the provision of a backing or supporting member made in a number of lengths, for example, three lengths, to carry one, two, or three ribbons and separate self-contained holders for each individual ribbon, the holders being arranged to be mounted in any desired combination on the backing member.

Another object of the invention is the provision of an improved construction permitting ribbon-holding members to be easily assembled on a backing and supporting member, the latter carrying means for attachment to the clothing of the wearer. In a preferred embodiment of the invention, the attaching means cooperates with an element of a ribbon-holding member for securing the pin to the clothing of the wearer.

A further object of the invention is the provision of a bar pin which can be more readily and economically manufactured than prior types, and which is better adapted to serve its intended function.

My invention will be more fully understood, and further objects and advantages thereof become apparent, when reference is made to the more detailed description thereof which is to follow and to the accompanying drawings, in which:

auaose Referring now to the drawings, my invention is disclosed in a number of embodiments, all of which include a common feature, namely, the provision of a base or supporting member which carries the fastening means, and individual ribbon holders adapted for ready assembly with the base or supporting member. The holders and members in each of the several embodiments disclosed are preferably made of light-gauge sheet steel, although aluminum or other non-corrosive metals may be employed. The base member is made in a plurality of sizes, suitably three sizes, to accommodate one, two, orthree of the individual ribbon-holding units. As will be readily understood, any combination of three ribbons can be carried by the three-ribbon backing member, and similarly any two ribbons may be car ried by the two-ribbon backing member, whereby a purchaser's requirements can. be met with a minimum stock on hand. Thus, if the supplier carries a stock of assembled ribbon units representing the various military campaigns, decorations. and the like, and a supply of the backing members in the three or more sizes, campaign bars can be assembled in any desired combination to meet the requirements of different service men.

In the embodiment illustrated in Figs. 1-6 inelusive, the bar pin comprises individual ribbon holders l and a base and supporting member l2. A two-ribbon bar pin is shown, but it will be appreciated that base member l2 will also be made in lengths to accommodate one or three or more ribbon holders iii. The ribbon holders l0 each include an outer shell ll, an inner plate or inlay l8, and a facing material or ribbon i8. The latter may comprise a campaign ribbon or the like, or any other insignia-bearing or ornamental flexible material. The outer shell i4 is provided with side flanges 20 for a purpose to be described. Inner plate It is of a size to fit loosely between the flanges 20 of plate i4 and is provided with a struck-up detent 22 for a purpose to be described. Both plates I4 and I8 include elongated slots 24 and 26 respectively to permit insignia of various types to be secured on the outer face of the bar pin, such insignia including stems which are passed through the aligned slots and bent over or threaded into nuts, or otherwise secured in position.

In assembling the individual ribbon-holding units Hi, the facing material i8, such as a campaign ribbon, is laid to overlie the front face of the outer plate It, with the ends extending over flanges 20 and onto the rear face of the outer plate. Inner plate 16 is then inserted between the flanges 20 to overlie the rear face of plate H and to confine the ends of the facing material between the contiguous faces of the plates. Flanges 20 are then bent or crimped to approximately the extent shown particularly in Fig. 4 to lock the plates in relatively immovable relationship to one another, with the facing material securely held in place. As will be noted from an inspection of this figure, the flanges extend rearwardly from the outer plate in converging planes, with free edges spaced substantially from the inner plate, whereby the facing material is confined between the flanges and the edges of the inner plate, and at the same time the projecting flanges serve as a reinforcing means to greatly strengthen the assembly against bending. In addition, the inwardly converging flanges define a channel substantially dovetail in cross section to receive the base or supporting member l2 in endwise sliding, frictional engagement. I! d sired, the assembled holders may be additionally crimped as indicated at 21 to ensure that the plates will not shift. The individual ribbon holders may be made up to carry the various different ribbons or insignia and stocked for later assembly in any desired arrangement with the backing and supporting plate as previously pointed out.

The base or supporting member l2 in the embodiment of Figs. 1-6 comprises a fiat plate of a width to fit with sliding friction between the overturned flanges V 20 of the ribbon holders (see Fig. 4). The base I2 includes struck-up wings 28, provided with inwardly projecting protuberances 30, preferably formed by indenting the wings. The wings are formed on their forward edges with extensions 29, which may be drawn together when the wings are assembled on the pin, the projections thus forming a fulcrum or rest to tension the pin outwardly when it is moved to its locking position (see Fig. Adjacent the opposite end of the base I2 is a keeper or latch 32 formed in part from a struck-up section of the member as illustrated. This end of member I! is preferably bent downwardly to form flange 22. A pin 34 formed with an eye 28 and a pointed end 28 is mounted on base l2 by pressing the wings 28 together with eye 38 confined therebetween until protuberances Ill substantially contact within the eye to define a pintle on which the pin may rotate. Elongated slots 40 are provided in backing member l2 for alignment with slots 24 and 28 in plates i4 and i8, theright hand ends of the slots (see Fig. 3) substantially coinciding with detent 22 in plate I to further secure the parts against disassembly.

To assemble a campaign bar of the type de scribed above, the selected, previously prepared ribbon-holding units are slid lengthwise onto a backing member II of the correct length from the right hand end (as viewed in Fig. 1), as shown in Fig. 2, until the forward ribbon-holding unit is stopped by flange 33 and the holders are in endwise contiguous relationship. The bar is then ready for attachment to the clothing of the 45 wearer. As shown in Fig. 3, detents 22 enter slots 40 and, in conjunction with the firictional fit of the backing member between the ribboncovered flanges 20, prevent the ribbon units from accidentally sliding of! the backing plate.

v eflect, a curved contour whereby it will lie flat against the clothing.

Referring now to Figs. 7, 8, and 9, a construction employing a modified form of the backing and supporting member is disclosed, the ribbon holders being of the type previously described. In this form' of the invention (see particularly Fig. 9), backing plate 44 is of a width to overlie the flanges of the ribbon holders and includes curved side flanges 48 embracing the ribbon units.

The ribbon units are suitably somewhat modified from the form previously described to the extent that the flanges of the outer member are bent downward to a greater extent than in the other forms to obtain a rounded edge for frictional engagement with curved side flanges N. In this embodiment ribbon units II) are inserted endwise into. the channel defined by flanges 46. The fastening means comprises a wire-like member 48 having outer projecting, pointed ends 50.

Member 48 includes a circular, preferably inte- Fig. 6 illustrates the adaptability of the bar gral eye 82 to receive a pin 84. A detachable keeper member 08 is provided comprising an elongated plate includulng bosses 88 to overlie pointed ends 50 and a central lock 80 having upstruck members 82 adapted to bite into pin 84 when mounted thereon and to resist removal forces, but removable from the pin when sufflcient force is applied, as by means of a tool. In the use of the pin, keeper member 88 is removed and the bar placed in position on the outer surface of the clothing, with pointed ends 50 and pin 84 projecting through the clothing. Keeper member 88 is then forced down on pin 54 to firmly lock the bar in position with bosses 58 overlying sharpened ends 80 of wire 48.

Referring now to Figs. 10 to 17 inclusive, a modified form of the construction is shown, this modification being preferred in many instances. As in the constructions previously described, the bar pin includes individual ribbon holders 88 and a base or supporting plate 84. The ribbon holders consist of a ribbon or other insignia 05,- an outer shell '66 of similar construction to shell 20 and formed with side flanges 88, and an inner plate or inlay l somewhat modified from that shown at l6. Inlay plate is provided with a cut-out tongue 12 having a central aperture 14, the tongue being adapted to be struck up from the material of the plate to assume a substantially vertical position, although normally lying in the plane of the plate, both positions 'being shown in Fig. 10. Plates 66 and 10 include elongated slots 16 and 18 respectively for similar purposes as slots 24 and 28 in the previous embodiment.

The base or supporting member in this embodiment of the invention will take diiIerent forms, depending on whether it is to support one, two, or three or more ribbon bars. Fig. 10 discloses the construction for a three-ribbon bar, base 84 in this instance comprising an end or tongue 82 of reduced width and of a length tobe positioned between the inwardly extending edges of side flanges 68 of a plate 66, with a bent-up tongue or keeper 12 of a plate 10 projecting therethrough asillustrated in Fig. 1'7. As shown. the reduced width of tongue 82 may be provided by cutting away the material of the member.

The portion of the member which forms the tongue may be bowed upwardly to provide the re- 86, preferably of similar construction to that shown in the embodiment of Figs. 1-5. A guide member 88 is also upstruck from member 64, the guide including a notch 90 to receive pin 84 ad- Jacent the sharpened end thereof (see Figs. 10 and 11). The end of member 64 opposite tongue 82 carries an integral flange or stop 82. Elongated slots 84 and 95 are formed in the base member, slot 94. which extends into tongue 82, being of a width to receive keeper 12 of plate 10.

In the assembly of a three-ribbon bar, two of the individual ribbon units, constructed as previously described are inserted on the tongued end of base member 64 and slid therealong until the forward holder reaches stop 92. Both of these holders have their tongues I2 in their original flattened positions within the plane of the plate. The tongue 12 of the third'holder is retained in its outwardly projecting position to constitute a keeper for the fastening pin (see Figs. 10 and-17) The third unit is then applied to the base memher by inserting keeper I2 through slot 84, with tongue 82 of member 84 inter-fitting between fianges'll. The bar pin is then ready to be worn. In attaching the bar, pin 84 is caused to penetrate the clothes of the wearer, and the third ribbon-holding unit, as shown at the left-hand end in Fig. 17,. is moved to the right until it lies in endwise contiguous relationship to the previously applied unit, the end of pin 84 entering perforation 14 in keeper I2-during such endwise movement. Notched guide 88 aligns pin 84 with perforation 14 to ensure entry of thepin into the perforation. Where the bowed end 88 of Piss.

25 and 26 is employed, the bowed end is preferably flattened after the three ribbon units are assembled on the base to prevent complete separation of the parts thereafter.

As indicated at 88 (see Fig. 17), the outer end]; of the flanges of the third ribbon holder may be further bent or crimped downwardly to ensure frictional contact with tongue 82 to assist in preventing accidental endwise shifting of the holder.

Referring now to Figs. 12 and 13, a construction for a single-ribbon bar is illustrated. The

ribbon-holding units are the same as before. A base member 88 is provided of a similar construction to member 84 except that, in addition to its reduction in length to accommodate a single ribbon holder, it is made of the same width throughout and an open-ended slot I00 is provided, terminating in an upstruck guide I02 of similar form to guide 88. The central slot 88 in this form is broken, leaving a short strip or bridge of metal I! adjacent the outward end of the slot, for a purpose to be described. v

In making the assembly of the one-ribbon bar pin, the unit carrying the ribbon, which is of identical form to that employed for the threeribbon pin of Fig. l0, but reversed end for end as indicated in Fig. 13, is inserted endwise over the notched end of base member 98. The pin is then caused to penetrate the clothing and its free end is supported in notched guide I02. The ribbon holder is then further slid on base 00, with the pin entering the perforation in the keeper 12 of the ribbon unit, the sliding motion continuing until the keeper I2 reaches the end of the slot I00. After the ribbon unit has been partially mounted on the base plate 08, the'strip or bridge i0! is pressed downwardly into the slot in the underlying inlay 10, thereby preventing complete separation of the ribbon unit from the base plate.

Figs. '14, 15, and 16 disclose a construction for a two-ribbon bar pin. The ribbon-holding units as shown in Fig. '16 are identical with those employed in the construction of Figs. 10 and 13. Base member I04 (see Figs. 14 and 15) is essentially the same as base member 98, except that it is of a length to support an additional ribbon unit. In assembling the construction, a ribbon unit with its tongue or keeper member 12 in flat position, as shown at the right hand end of Fig.

16, is first slid onto the member I04 from the slotted end thereof until it reaches the flange or stop. The second unit. in reversed position, as shown in Fig. 16, is then inserted on base member I04 and the bar pin attached to the clothing in the identical manner described above in connection'with the single-ribbon pin of Figs. 12 and 13. The bridge I05 is constructed and utilized the same as bridge l0i in the single pin.

-' Asshown in Figs. 10, 12, and'14, the forward ends of the base member are in each instance,

suitably rounded to prevent"catching of the members on the ribbons when the ribbon units are passed over the base, with the flanges I gripping the base.

Referring now to Figs. -18-21 inclusive, a further form of the invention is shown. In this construction inner plates Ill of the"ribbon-holdin: members are provided witlilaterally extendin: slots Ill adjacent an end thereof (see Fig. 21). Basemember III .(see Fig. 20) includes a hinge pintle Il2,-preferably of similar construction to that previously described, and a struckup guide I ll substantially corresponding to guide it or I02 of the other forms. The end of the base member opposite the hinge pintle is provided with an elongatedslot II! adapted to be subsequently closed at its outer end by an upwardly bent integral bar III. A keeper member I20 (see Figs. 1849) is constructed from a thin metal strip, the keeper member including base flanges I22 of a combined area substantially equal to that of slot I" to flt therein, as shown in Fig. 18. Upstanding integral extensions I24 of the base members I22 form an eye I28 of an outer diameter to pass through slot II! and of an inner diameter to receive the attachment pin.

In the assembly of a bar pin of this form, the ribbon holders are constructed as previously described except that elements I" are employed as the inner plates. In the two-ribbon-construction shown. a ribbon holder is slid onto the backing member from the notched end thereof in the same manner previo described in connection with the other em ts. The second ribbon holder, with the base of a keeper member I20 received in slot I" and positioned to have the keeper adjacent its outer end, is then similarly slipped onto the backing member until it contacts with the flrst installed ribbon member. Upstruck flange II! is then bent downwardly into the plane of the backing member to prevent complete withdrawal of the second ribbon-holding member. As will be understood, the secondribbon-holding member can be moved backand forth to an extent limited by contact of keeper member l2. with the inward end of notch II. and with flattened flange Ill. The fastening pin carried by pintle II2 (not shown) is made of a length to be received within the eye of the keeper I20 when the ribbon holder is moved to the right, and to be released when the ribbon holder is moved to the left.

As will be appreciated, this construction is adaptable to bar pins carrying one or three or more of the ribbon holders without change except for the difference in length of the backing member and the length of the slot II.

- Referring now to Fig. 24, a slight modification of the last described embodiment is shown. this case inner plate I28 of the ribbon-holding member includes slot Ill, similarly located to slot Ill, but of lesser transverse dimension than the combined extent of flanges I22 of keeper I20. As a result the base of the keeper is confined between the inner and outer plates of the ribbonholding member, the keeper being inserted during the assembly of the latter. In this case the keeper I2l will be formed on each ribbon unit and will be flattened down on all except the last unit to be passed on to the base.

Figs. 22 and 23 disclose a minor modification of the fastening pin which may be employed in any of the several embodiments, although illustrated for use in the embodiment of Figs. 18-21. The hinge pintle previously described is eliminated, and in lieu thereof a pin I22, formed of spring wire or the like, is provided with an integral coil spring I, terminating in an end I" passing beneath a portion of the backing plate and extending through an opening therein to be locked in position as illustrated particularly in Fig. 23. Owing to the presence of integral spring I, the pin tends to swing outwardly from the backing member. Hence, when the end of the pin is confined by the keeper member, an additional frictional resistance to movement of the keeper is obtained. In addition, the pin is in a superior position for attachment purposes.

In Fig. 27 there is shown a slight modification of the ribbon holder, wherein instead of a flat plate It of Fig. 10, e. g., being used for the inlay, this element It. is of the same form as the outer shell. so as to more firmly grip the ribbon between the outer shell and inlay. It will be understood that this inlay I" may be supplied with a keeper of the type herein disclosed in Figs. 10, 18 and 24 or that it may have a smooth face as in Fig. 1.

Having-thus described my invention in rather full detail, it will be understood that these details need not be strictly adhered to and that various changes and modifications will suggest themselves to one skilled in the art, all falling within the scope of the invention as defined by the subioined claims.
