Ap l cat an ary 2 lei-zoom No. 261.54 r'olai'iiif (entre -=56) This invention relates. generally to dispensing devices and more particularly it relates to card or tag dispensers. Theinventiond'is'closed in is an improvement over that disclosed in my 'copend'ing application SeriaI'N'o. 94,.483, fi1ed May 120, 1949, now abandoned.

It is customary in feed mills and} ih- Vari us other industrial establishmentsto close bags of grain or other materials by sewingv and it is. re-

qui'red by State regulation that a ta-g be attached to each. bag showingv the ingredients of the material in the bag. Certain mechanisms have been suggested for feedingv a tag or card into the line of stitching to be caught to the needle of the bag sewing machine,v but such mechanisms are unduly compl'ex'and expensive.

Prior art devices of the class described above include mechanisms designed to prevent the neotion of more than one card at a time, but such mechanisms are also subject to criticism as unduly complex and expensive,

Accordingly, it is the primary object of this invention to provide a novel card dispenser, and it is a further object of this invention to provide a". card dispenser. which is of siirpl'e construction and inexpensive to manufacture;

Still another object of tjliis invention is to pro:

vide a card dispensing device including a novel mechanism. for permitting] ejection of a single card only at a given time}. such mechanism b In accordance with this invention, card sje'parating means is disposed. in the path of an ejectable card comprising, a Ireniher adapted to de;

The purpose of the p'arallelo gram form will be explained subsequently. cards S m-a5; .be stacked vertically on edge Within the box, there being a gravity moveable Weight T disposed to the rear of the stack for m ing the cards ldown firmly into contact with the front won 850i box 1 Weight "5 may be any cylindrical member of sufficient mass to move cards {5 downwardly whereby as cards are ejected 'frtiin the box, there is certain to be at least one card in position for ejection. Another purpose for weight I will appear from subsequent descrip- ;tion. 130?: I is provided with a slot [0 th ough which cards may be ejected in a manner to be .descril oed. V I I For ejecting. cards. 5 from box I there is provided ale've'r. I2 attached to a sliding memberil} extending from the lever to the cards 5 in the box. Lever 12' serves as an operating me ber Ivvh'ioh may be manually or power operated. Member rs is pivoted at n toa'slide is moooteq in the track or guide 23 which is slotted at and} isfiXed to the front 8 of box I in an e u known manner. For the purpose of positively :enga thelowerfmost oifront card of :I-, there is provided, on member 1 3 at its outer end, a sa vv -tooth member 213'. As illustrated no 3,,the saw-toothed member 2:8'1n'ovesthrough a slot 36 provided in the front 8 of box Lthrough a idi'stance sufficient to allow member 2 8 to g ge the outerrnost card. For ncrinail' rt Suz e lg inits inactive position, there is fp ovided a spring 2%,. attached at one end; to slide 1 8 by a s rew 21' and at its other endto a me jjfiigedto th sideof Box I. Pulley 3 Inount edfl o n guide 23 serves to guide spring 261 For' thle purpose of separating the outermost "om the next outerinost card 33'; there .j fi ljd t isprov de'mn the path of movement ofan eje'ct ed card, a stop 35 moveabl y mounted by nieans Q of screw 35 which may be fixed to end memjbii the ioox I s illustrated in Figures '2 one 4 o: the drawings, Stop Siiiznay be a spring mom her and is slightly bent as at 38 into a:-s1ot- 3 9 forrned in member 3?. Stop 35 is bent is areverse direction, as atiii, intoapproximate alignment with the plai'le ofside Stop'35 extends,

across slot 0 into. alignnienttviththe inside surface of frori t Wall E and to a positiontointerq rdtz' and also deflect it as iliustrated in Figures 2 and 4. The front 8 is providedivitha cavity as at 4| of sufficient depth to permit slight bending of the midportion 42 of a card so that a card 32, which is positively engaged by member 28, may bend at its midportion 42 and slide outwardly past the stop whereas card 33, which is only frictionally engaged by card 32, will not bend and will meet the stop whereby the frictional engagement will be broken to prevent the ejection of a second card.

For purposes of illustration of a typical application of this invention, Figure 2 includes a showing of a portion of a conventional bag sewing machine looking downwardly. Such a machine includes a frame 43 and a foot 44 whereby, in normal operation, the end portion of a bag moves between the frame and the foot for sewing by the needle (not shown) and a card such as 32 may be ejected into position to be sewn along its upper edge to the bag. The card dispenser may be arranged with respect to the sewing machine in any suitable manner to achieve the desired result as will be obvious to those of ordinary skill in the art. However, box I has a parallelogram form so that the mounting supports may be spaced appreciably from the sewing machine but the dispensing slot may be closely adjacent the sewing machine.

In operation, a stack of cards may be placed in box I, by removing weight I, inserting the cards and then replacing the weight I. As a bag is being sewn, the operator of the sewing machine, at any desired stage of the sewing, may move lever l2 to the left (Figure 2), thereby pivoting member [3 clockwise to the position shown in Figure 2. Member I3 pivots with lever 12 until saw-toothed member 28 engages card 32. Because of the resistive action of weight i the teeth of member 28 will pierce card 32 to a slight degree. Thus cards 32 and 33 are moved into engagement with the curved end of stop 35. The

very tip end of stop 35 is in approximate alignment with the inner surface of front 8 of box I,

and therefore, card 32 must bend at its middle portion into cavity 4| the degree of bending being at least equal to the thickness of the card. It I should be noted that front 3 prevents bending of card 32 except at its mid-portion whereby greater force is required to eject the card than would be required if the card were permitted to bend across its entire width as shown in my 00- pending application, identified previously. Because there is positive engagement between member 28 and card 32 this card is forced to bend and slip past the stop 35 as shown in Figures 2 and 4. However, when card 33 reaches the stop 35 it is spaced inwardly from the tip end of stop 35 a distance at least equal to the thickness of card 32 and therefore would have to bend at its midportion through a distance equal to its own thickness plus that of card 32 before it could pass the stop 35. This cannot happen because there is only frictional engagement between the cards 32 and 33 and the friction is not sufficient to cause continued movement of card 33 with the force necessary to bend it outwardly beyond the tip end of stop 35.

disengage the saw-toothed member 28 from card 32 and move slide l8 back to its starting position and therewith the associated mechanism. By repeating the cycle described above, one card after another may be sewn to one bag after another until the cards are all ejected from box I.

As mentioned hereinbefore box I is formed in the shape of a parallelogram, has a sloping bottom and a gravity movable weight 1. Weight 1 serves to counteract the pressure exerted on the cards by the card ejecting mechanism. As the cards are ejected weight 1 moves downwardly, and the right hand side of the box moves weight I to the left whereby the left hand end of weight I is closely adjacent to the side 31 of box i. If at any time the pressure of the card ejecting mechanism becomes excessive, the left hand end of weight I binds against the inner surface of side wall 31, thereby preventing excessive inward movement of the cards.

While this invention has been illustrated as applicable to a bag sewing machine, it will be obvious to those skilled in the art that there are many other applications for card dispensing devices. Also, it will be obvious to those skilled in the art that many types of boxes may be utilized with this invention. In fact, an open frame may serve the purpose in certain applications. It is further noted that this invention is not limited to the use of cards, as it may also serve to dispense metallic tags.

While there has been described what is at present considered the preferred embodiment of the invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention, and it is, therefore, aimed in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.

I claim:
