APPARATUS FOR CARDING SAFETY PINS.

Application filed March 19, 1924. Serial No. 700,209.

This application is a partial continuation of my eopending case, Serialv No. 551,972, liled April 12, 1922, and containsA subject matter taken therefrom. y

This invention relates especially to apparatus for carding safetyf pins and similar articles by forming thercards with transverse or other slots or apertures into which the closed or locked safety pins may be inl serted, particularly if the card is trans versely arched up when the pins are inserted in the slots. Then a breakable cardboard or other retainer strip may be slipped along the bach ofthe card and may preferably have bottom or edge projections so as to interlock ivitli the inserted pins anc securely' and positively retain them in position until they are removed for use and thereupon tear er break the retainer strip which is preferably adhesively secured to the card backv at a number of places or positively retained in position as by interlocking projections, tongues and apertures formed in the cooperating portions of the strip and card or pins. The card may be conveniently supported and forced into its transversely arched up position in a card holder having inclined card grooves on each side, so that. when the card is forced longitudinally into the grooves or when the grooved edge portions apgroach each otherthe card is arched up transverselyalong its centre line or where the transverse pin slots are formed therein. A dozen or other desired number of closed safety pins may be placed or fed into a suitable pintransfer block having slots to receive them and may be hereby transferred and accurately placed in c00peration with theV pin card so that for instance their point portions enter and pass through the card slots sufficiently to allow the retainer strip tobe inserted from the same or lthe opposite direction as the card. T hen the pins may be ejected fromA the transfer block by any suitable device and the card released from the holder and discharged therefrom as by the insertion of another unfilled card into the holder.

In the accompanying drawing showing in a somewhat diagrammatic Way an illustrative embodiment of this invention Fig. 1 is a central longitudinal section through an illustrative carding apparatus;

l Fig. 2 is a transverse section showing the strip feeding and .gumming devices;

Fig. 3 is a transverse section thereof taken substantially along the line 3--3 of Fig. l;

Fig. 4t is a rear view of the resulting Vpin card or package, and Fig. 5 is a section thereof on line 5 5 of Fig. 4L.

The pins may be carded or packaged according to this invention While remaining in their closed o r locked condition in which they are regularly tumbled and polished and for this purpose the pin cardlt is formed with one or more series of pin slots such as 1G `which may be transversely arranged when a single roiv of pins is to be arranged on the card. The pins preferably have their point meml'iersv inserted through these slots V(Si) which can be readily done by hand or other- Wise, especially if the pin card is transverse-v ly arched up vby any suitable means; and when all of these safety pins, rings or other generally 'similar articles have been inserted into their slots, a cardboard or other retainer strip or member l5 is inserted between; the card back and the projecting portionsio'f the articles extending through the slots so, as to hold them in position during shipmentv around the reduced end 7 of the pin so asV to tend to separate the card liolclersectioiis when the bushing 33 is screivedvin behind the spring.

more cams l0 pivoted about the pivotsV l1 in the endsof the pins 7 so that when the ends 12 of these cams are swung upward into the position indicated in Fig. 3 the card holder sectiensare closed against the action of these4 springs 29 and the card 14 is'thereby forced up into the definitely transversely arched up position indicated. The card holder lis preferably formed with inclined These sections may, however, be closed by suitable devices such as one or card grooves i on either side of the same so that underthese conditions the card edges are force l down alongv these inclined grooves to the c .rved bottoni j uortions thereof, the arched up lower surface of the card holder recess j n'oinotinfY the desired posit-ion of the card adjacent l isc eove edges rlhe safety pins or other generally similar articles may be inserted in any sanitableV way in these pin slots in the card which are preferably not more than aboutha-lf as long'as the safety pins in order to more definitely hold them in position. For this purpose a pin transferl block; such as 18V is K4desirable insupportingthe-series of pins and facilita-t.n ing theirinsertionin the slots in the card. This transfer blocwlg may be formed wien series of pinslotslwhich may extend com.-

rpletely through the block from top to bot-1-V tom, ifd'esired, and'be' spaced apart so as to correspond with the slots inthe cardl 14..

To retainthef pins in position inthe transfer-block any suitablefholding devices suchv asoneA or more pin supportingv plates 2O may loe-employed and mounted, if desired,

onthe pinsl projecting from each side of the transfer block 18 andV normally forced inwardiinto the position indicated in F ig. 3 bytheflight-splrings 21 so that the series of safetyV pins are thus supported by the inwardly projecting edges of Vt-hese plates. These-plates may, however, be released so as to simultaneously release the series of safety pins fromthe transfer block andfor this purpose the plate releasing cams 22 may be arranged on or adjacentV the upper face of the transfer block so as tobe engagedby the edges 2d ofthe pin releasing block 23 during the downward movement toward the transfer block so that it then wedges out-l ward these'releasing cams andthe connected pin supporting plates 20. If desired also resilient or rigid ejector members may be provided on this releasing block` and'one or,

more pin ejector-lugs 27 may be formed or yieldably mounted thereon so asto engage .the safety pins preferably after the supporting plates have beenl substantially released andf thereupon positively eject Vthe safety pins from the transferblocl; by passing into the slots 28 in theblocl. The releasing bloclt may be supported and operated in any desired wayA as by the tubular carrier membersl 26 whichv may extend aroundv the carrier rods secured to the die agonally opposite corners orportions of the transferblock, for example, these carrier elements being operated manually or mechanically in any desired way.

Y In using thisN apparatus to formfthepinl i packagel described the pin card lllmay be inserted intothe laterally openedgrooved card holder asb'ythe feedroller 50 which. engages the` lower v face ofjthe card "beneath nallydischarged from the holder,if desired. p

l/hen the card is longitudinally positioned inthe holder the holder Vsections may be broughtV together as by the closing cams l0 so as to transversely arch up 'the card, which may thus be forcedup at its central portion somewhat above itstransverse guide ribs 3 formedin the upper surface of the card holder and the pin recesses 13 vtherein as shown in Figs: l' and. Then a series of safety pinsmay be brought into proper engagement with the card as by the pin transfer block 18 so that the point or other portionl of each pin is preferably pushed through theV corresponding pin slot 1n the cardto ay sufficient extent'to leave an opening into which-the retainer `strip l5, having bottom or edge corrugations such as to accommodate the pins and preferably having gummed or otherwise adhesive upper surface or portions, 37 may be inserted as by the strip feeder l. vAs the retainer strip is" fed forward over the guider l5 by the feeder l or other means, the gumming roll LiO'is simultaneously rotated so as to apply any; suitable adhesive from the tank `a4: and supply roll t3 to the desired ypart, of the retainer strip. 'As shown in@` ig. 4l, the strip may have rounded.'y edge corrugations or locking projections. extending between adj acent pinsfto be thereby secured in position, and these edge projections may be ladvantageously gummed as by Contact with the lateral projecting flanges orfconical portions 1-2 Vof the gumining roll 40, see Fig.y 2. rlhese gummed edge projections are of course strongly forced Ainto engagement with the card. back as soon as the card is released from the holder so that it can spring baci; into flatter position which forces the pins and interposed retainer Vstrip upward. Other separated or continuous gummed portions may be Vprovided instead of or in Vaddition to these gummed edge projections, and for this purpose the gumming roll l0 may have projections il at the proper intervals to apply the separated spots 87 of gumto the back of thestrip l5, preferably between each two adjacentpins.'Y The retainer strip is guidedva's by suitable guides d5, 48 so as to pass beneath;V the arched up card 16 and above theV pins projecting through the 4card Iil) as is seen in Fig. l, the one or more feeders l passing through suitable slots such as 49 in the gumming roll 40.

Thereupon the pins may be released from the transfer block as by the further descent of the releasing block 23 which releases and ejeets the pins from the transfer block and also, if desired, forces portions of the gummed or adhesive surface of the retainer strip into holding engagement with the card back as by the downwardly projecting end or other portions suoli as 34, 35 of the releasing block which may force these card board elements tightly together. The trans` fer and releasing block may then be withdrawn and the card of pins withdrawn from the card holder preferably after the holder sections have been opened at least to some extent to facilitate this withdrawal.

In some cases it is advantageous to employ interlocking projections or tongues and apertures formed in the cooperating portions of the retainer strip and card. This method -may be employed alone or supplemental to the adhesive method. As shown in Fig. 4, any desired number of apertures 38 may be formed in these parts as by severing them along the crossed or perpendicular dotted lines 37 by means of one or more sharp edged piercing members, and then forcing back against the adjacent rear face of the retainer strip, for instance, the interlocking tongues or projections 39 which are thus formed. There this is done by a stamping or die operation under heavy pressure, the adhesive which has preferably been applied between these parts, tends to become quickly set as in box staying operations and materially helps to hold the parts together in such positions as are shown in Figs. 4 and 5. If desired, however, a number of apertures such as 38 may be pierced in these cooperating members of heavy paper or light cardboard so yas to force the tongues 89 through tiis aperture after which they may `be advantageously forced or crushed down against the baclr of the retainer strip, for example, to prevent accidental longitudinal displacenient of the retainer strip.

rl"l1is invention has been described in connection with .a number of embodiments, forms, proportions, parts, arrangements, materials, methods of connection, operation and use, to the details of which disclosure the invention is not of course to be limited, since what is claimed as new and what is desired to be secured by Letters Patent is set forth in the appendedl claims.
