Y i3 Claims. (Cl. 2li-18d) This invention relates to a clip dispenser and cartridge loader. The invention is particularly useful in the rapid and accurate loading of a dispenser for paper clips and to mechanism for ejecting the loader cartridge andl for dispensing the clips separately thereafter through successive manipulationsof the dispenser.

- The present application is a continuation of my copending application, Serial No. 42,430, filed July l2, 1960,

now abandoned which in turn is a continuation-in-part of application Serial No. 852,373, tiled November 12, 1959, and now abandoned.`

In the dispensing of paper clips, and the like, it is not only important to provide means by which the clips can be ejectedfor grasping through easy manipulations of the dispenser, but it is also important that the clips carried by Ithe cartridge be supplied to the dispenser and stripped from the cartridge in a quick and accurate manner. Paper clips, because of their elongated shape, may be easily misaligned, and means for accurately holdy `ing a large number of clips in alignment must be prodispenser, may be ejected, leaving the clips in position for individual ejection. Another object is to provide a Aclip holder for moving clips in aligned position into the magazine of a dispenser while at the same time effecting the rapid ejection of the holder from the magazine. A still further object is 'to provide a new cartridge holder carrying paper clips in aligned 'position which may be ejected to leave the clips within the magazine of the dispenser while at the same time being insertable within the dispenser to pick up any misaligned clips for realignment. Yet another object is to provide an improved dispenser having a minimum o-f parts which is effective in feeding clips separately from .the dispenser as needed .through a simple vertical reciprocation of the 4dispenser magazine. Other specific objects and advantages will appear as the specification proceeds.

The invention is shown, in an illustrative embodiment, by the accompany drawing, in whicha dispenser and clip holder; FIG. 2, a broken, part-longitudinal sectional view; FIG.-3', a side view in elevation ofthe clip holder or cartridge; FIG. 4, an end View in elevation; FIG. 5, a sectional view, the section being taken as indicated at line 5 5 of FIG. 3*;-FIG- 6, a sectional view, thersection being taken as indicated at line 6-6 of FIG. 3'; FIG. 7, a broken, enlarged, detail view of the clipl holder in engagement with a paper clip; FIG. 8, an end View showing a modified form of structure; and FIG. 9; a broken top plan view of a modified form of clip holder.

In the illustration givemA designates a base member, 4B varnagazine member pivotally mounted on said base n inglrz in the top member C.

member, C a top member pivotally mounted upon saidV j r magazine member, and D a fastener holder.

The base member A may .be formed of any suitable y xtends through the rear por-tion of the base member A and magazine member B to pivotally support the maga- I 1S in the bottom wall of the magazine member B and the ejector is then turned forwardly to form a latch head 19 asshown more clearly iny FIG'. 2. The ejector thus serves a dual purpose, namely, latching themember B against upward movement and also engaging the foremost fastener and elevating it when the magazine member B is depressed vto eject the fastener through open- The magazine member B, as shown best in FIGS. 1 and 2, has channel sides 2t? and 21 connected at their rear with an apertured rear wall 22. At its front, the magazine member B is provided with vstripper bars 23 andy 2d. The stripper bars are formed by turning the ends of the side wall-s Z@ and Zi inwardly, and they provide between them an escape passage 25 through which the support for a cartridge of clips may be ejected during the loading of the magazine B, as will be later described.

The magazine B is Aapertured to receive an ejector rod 2d having a handie 27. The rod extends through a pusher block or follower 28 which is urged forwardly by a coiled lspring 29 against the paper fasteners 30. The follower is provided with a rearwardly-extending portion 3l and may be apertured at 32. to receive a suitable latch (not shown). lf desired, the follower may have interlocking connections with the sidesvlfor causing the follower to travel straight andy in alignment with the sides of the magazine. The follower is provided centrally with a rearwardly depressed portion 33 apertured to receive the rod 26, and the head 3d of the rod is adapted to engage the follower within the, recess so that the rod may be employed to retract the follower 28, when this is desired. y

The fastener holder or magazine D may be formed of any suitable material. In the Ispecific illustration given, it is formed of resin plastic and it has a handle portion :i5 provided at the top with a horizontal flange 36 and with the. support beam members 37' and 38.,- The member '37 merges with a resilientflnge-r 39 having at its end a rounded catch dit. The member 3S is provided with a slightly depending heel dit and with a recessed portion 4Z adapted to receive the head 31 of ejector rod 2d. Above the vrefyessliZ. is a stop portion i3 which is connected by the intermediate memberl d4 yto the beam 37. A thin web 37a extends between the ribs or` beams 37 and 3g and between the ribs 4d and 3S, as shown more clearly in FiGS. k5 and 6.

Operation In operation, the member D may be filled with fasteners 3G by inserting the fasteners over the end provided with the flexible finger 39. In actual practice, the fastener-forming machine may be utilized for feeding the fasteners as formed over the fingers 39 and onto the magazine D. With themagazine member D filled with fasteners as shown in FIG. 2, and with the follower 2S retracted, the member D can be inserted within the magazine to the position shown in FIG. 2 and the holder D may then be ejected by pressing the rod 26 forwardly, in this operation theV spring finger 39 yielding whileat Ythevsame time beingejec'ted without disturbing the alignment of the fasteners Sti. In face, it is found that Vthe ejecting of the member D with the yielding finger 39 engaging the fasteners, there is an aligning action of the fasteners so that they are left in accurate alignment as the member D is withdrawn. In the foregoing operation, the rod 26 operates independently, serving to push or eject the member D after the fasteners are placed within the magazine and also serving, upon retraction, to engage the follower or pusher member 28 and retract it to any desired position.

In the ejection operation, the rod 26 tits within the recess i2 so that the pressure is centered within the holder D for accurate removal thereof.A As the member D is ejected, the

stripper bars

23 and 24 engage and retain the fasteners 3ft? as they are urged forwardly by the pusher member 28. The width of the

members

37 and 38 is such as to substantially fill the space on the inside of the `fasteners so that free movement is avoided and the fasteners are firmly held in the loading operation. The stop member 43 limits the downward movement of the resilient finger 39 so as to avoid breakage, while at the same time permitting suiiicient inward movement of the 4member 39 to allow the member D to be ejected.

In the illustration'set out in FIG. 8, the side walls 20a and 21a of the magazine B are provided near their bottom with U-shaped lateral extensions 45 for receiving the laterally-extending legs 46 of the follower 28a. The

kmisalignment the dispenser does not properly function.

It is found that the misalignment can be corrected instantly by pressing the member D inwardly through the

stripper bars

23 and 24 so that the fasteners are reengaged by the member D and the action of the resilient leg 39 serves to realign the fasteners. Not only does the plastic clip holder prevent misalignment when it is feeding the clips into the magazine chamber ,and while the cartridge or clip support is being ejected, but also the clip holder, with its resilient leg, is effective in picking up t-he clips in case of a jam to bring about quick realignment of the clips within the magazine channel.

In the modification shown in FIG. 9, the holder D1 is provided with two resilient legs or fingers 47 and 48.'
