Referring now to the figures of drawings, in all of which like parts are designated by like reference characters, the dispenser of this invention comprises a base 10, a clip storage compartment 11, clip holding bracket means 12, clip selecting means 13, paper, etc. retaining means 14, manually operable means 15 for operating the clip selecting means for selecting an end clip from a plurality of clips stored in the magazine compartment, and means 16 for dispensing and spreading said selected clip and guiding the same toward the sheaf of papers, etc. held in said device to clip the same together. In the form shown in these drawings the clip applicator is also provided with cutting means 17 adapted to be operated by said manually operated means to separate said end clip from the remainder of the stored clips prior to its selection and dispensing Where the same are adhesively or otherwise secured together and loaded as a unit in the storage compartment.
The storage compartment 11, it is to be noted, is disposed longitudinally of the rectangular base 10 and preferably positioned thereon by rivets 18 or the like.
Said compartment is, in the form shown herein, provided with a central portion 19, U-shaped in cross-section, and a leg of said U, 20, is provided with an inwardly projecting stud 21 or guide at the entrance end of the magazine or storage compartment 11 and is positioned adjacent the base end of the leg 20 wherefor it is adapted to contact and guide clips 22, which in the form shown are of loop form, underlying and abutting the free end of the outermost loop thereof, which forms a shoulder 23. The clip is preferably positioned in this manner for optimum ease of application.
As hereinbefore related the clips when loaded are preferably adhesively or otherwise secured together formingan integral block of clips 23 for loading. The said block of'clips23 is inserted into the U-shaped opening of the magazine 11 and is yieldingly retained therein by a pressure means 24. Said pressure means comprises a rod 25 which, as shown in FIGURE 2, is generally J-shaped, having astem portion 26, and a hooked end portion 27. The hook 27 is, in the form shown, provided with a notch 28 in the projecting end 29 thereof. The said end 29 of the rod 25 is adapted to be projected through an aperture 30 in the web 31 of the portion 19 of the magazine 11 and the stem 26 of the rod is provided with a pusher element 32 of generally the contour of the clips, the same being adapted to be pressed against the rearmost of the said clips or block of clips 23'.
Coil spring means 50 is provided telescoped over the longitudinally extending or stem portion 26 of the rod 25 and is seated at one end upon an annulus or disc 51 secured to an intermediate portion of the rod portion 26 adjacent to the hook portion 27 thereof; the forward end of the coil is seated against the pusher element or against bracket means 33 secured thereto, said bracket in the form shown formed similarly to the pusher element 32 but provided with an offset central portion 34 against which the spring impinges. The pusher or clip pressure plate 32 is as illustrated centrally apertured at 35, said aperture 35 being in alignment with an opening 36 in the offset portion 34 of the bracket 33 and the stem 26 projecting through both aperture 35 and opening 36. The rod is thus adapted to bias the clips forwardly as shown wherefor the innermost clip 38 of the clips and the next clip thereto 39 are retained in predetermined position for separa'tion of said end clips, and for selection, guidance, and separating, and receiving papers presented thereto.
To load the magazine, adhesively secured clips of the conventional or loop type are inserted into the magazine. The shoulder formed by the free ends of the outer most loops of each clip is placed over the stud 21 and the clips are moved forwardly in the magazine by insertion of the pusher element in the magazine. The elements 32 and 33 are provided with shoulders on either of the sides therer of on opposite ends as shown at 40, 41, respectively, Wherefor when the clip pressure means 24 carrying the same is inserted into the magazine the same is aligned and guided by the guide means 21 projecting inwardly in the magazine into contact with the rearmost of the said clips; the rod 25 thereof is then locked to the web by insertion of the notch of the said hook 27 thereof into the opening, the notch engaging the peripheral walls surrounding said opening and spring pressure retaining the clip pressure means 24 within the magazine and in pressure engagement with the clips urging the same forwardly in the magazine wherefor the innermost end clip 38 is in position later described herein.
The innermost of said clips 38 is positioned, as shown, within a U-shaped opening 42 provided by a retainer plate 43 and an opening 46 in clip holding bracket member 44, both of which are secured in the embodiment illustrated to a second clip holding bracket 45 which is provided-with a foot 45, the latter being generally L-shaped in cross-section: the foot beingsecured as by rivets to the base forwardly of the clip storing and dispensing compartment or magazine 11.
Each of the brackets 44, 45 and the retainer plate 43 are provided with aligned openings 46, 47 and 42, respectively. The opening 42 in the retainer plate 43 is, as stated hereinbefore, generally U-shape and is preferably larger than the U-shaped yoke of the clip magazine 11, surrounding the same. The said first and the second brackets 44, 45 are provided with centrally disposed longitudinally extending slots 46, 47, respectively, generally nar- 4 rower and of greater depth than that of the centrally disposed open end slot 42 in the retainer plate 43. The openings 42 and 46 in the retainer plate 43 and bracket 44 provide clearance for the width and depth of a clip and accommodate a second and first clip respectively therein, the opening 47 in the bracket 45 being of narrower extent throughout the lowermost depth of the slot 47 than the width of the clip thus holding the end clips in predetermined positioning and preventing their dislodgernent other than by the dispensing means. FIGURES 4 and 7 illustrate the end clip positioning within the clip seating pocket formed by the openings 46, 42. It will be noted that the slot 47 is of such width and extent in its upper portion to permit spreading and withdrawal of the end clip therethrough. See FIGURE 7.
The brackets 44 and 45 are further provided at their upper ends with sloped or inclined ramps 48, 49 adjacent inclined upper slotted portions thereof. A cam plate 60 is secured to the clip retaining means including brackets 44, 45 and retaining plate 42 by rivets 61 and is also provided with a centrally disposed elongated closed end slot 62 and a pair of longitudinally extending slots 63, 64 disposed on either side of said central slot; said laterally disposed slots are relatively narrow and provide a pair of downwardly extending legs 65, 66 wherefor the cam plate is adapted to be secured by the rivets 61 to the clip retaining means as shown.
The upper portion 67 of said cam plate forms an apertured yoke joined by shoulders 68 to the legs 65, 68 serving to space the upper portion of said cam plate from the innermost clip bracket 45. The cam plate is further provided with inclined or camrning surfaces 69, 70 on either side of the central opening 62 in said cam plate generally medially of said apertured central portion of the plate.
The upper edge of the cam plate is inclined, as indicated at 71, oppositely to the inclination of the inclined upper surfaces 48, 49 of the clip brackets 44, 45. A generally U-shaped spring member 72 is secured as by rivets 73 to the inner surfaces of the inclined surfaces 71 of the cam plate 60 and said spring member is provided with inwardly bowed portions 73 and preferably inturned ends 74.
The cam plate 69 and the clip brackets 44, 45 thus form a pocket for the reception of a stack of papers adapted to be vertically inserted therein and the bowed portions 73 of the U-shaped spring element 72, secured to the cam plate 60 are adapted to exert spring pressure on said papers when the same are inserted in the opening between the cam plate and the brackets and the same are held therein for reception of the clips.
Manual means 15 comprises manually operable means or tongue 80, an L-shaped standard or slide bar 81, and a base 62 secured in spaced relation to the base 45 of the clip bracket 45; the slide bar 81 is disposed vertically in general parallel relation to the body portions of the clip brackets and to the vertically extending portions of the cam plate 60. The manually operable means has a transversely extending slot 84 which is adapted to receive the vertically extending portion of the slide bar 85 which has a pair of oppositely disposed outwardly extending ears or lugs 86 on either side thereof and an inturned end portion 87 adjacent its lower edge parallel to the portion 80 of the slide and said portion is provided with a transverse slot 88 whereby the slide piece is movable in an upward and downward direction on the slide portion 81.
A clip divider or separator 17 having generally U- shaped flat yoke 90 centrally slotted as indicated at 91 is adapted to be disposed within a space or pocket provided by an offset center portion 92 of the retainer plate 43 and the vertically extending portion of the bracket 44, said space permits cutter surfaces as shown at 93 to penetrate and sever adhesive between adjacent of the clips, as best illustrated in FIGURE 4 and as described hereinafter. Arms 94, 95 are integrally secured to and extend rearwardly on opposite sides of the yoke of the divider 90 and said arms enter the pocket for the yoke 90 through slots 63, 64 in the cam plate 60 and aligned slots 46', 47 on either side of the brackets 44, 45.
The depressible slide piece is apertured as shown at 100 to provide a journal for a rod 101 secured to the base of the slide bar 81 and the 'base of the dispenser, as by rivet means 102. A generally C-shaped clip means 103 secures the rod to the slide.
Compression coil spring means 105 telescoped over the rod 101 is seated upon the base 82 of the slide bar 81 and against the under surface of the tongue 80 of the slide to exert spring pressure upon the thumb engaging tongue 80 of the slide biasing the same upwardly and adding spring resistance to the cutting and selecting means upon movement of the slide piece downwardly.
The clip pick-up is provided by pick-up means or selecting means 13, the said clip pick-up being a generally inclined J-shaped cross-setional flat strip of metal having the upwardly extending end of the J, 110, secured to the lower portion of the inner face of the slide piece by rivets 111 and its stem 112 provided with outwardly extending upper spaced ends 113, 114 having a pair of inwardly curved cam follower portions 113', 114' adapted to ride on either side of the central slot of the cam plate 60 and on cam surfaces 69, 70 thereof.
A curved tongue 115 is positioned between the said spaced ends 113, 114 and is adapted to be projected through the central slot 62 in the cam plate 60. The cam follower surfaces or portions 113', 114' of the clip pick up element 13 are adapted to cam over the camming surfaces 69, 70 wherefore the inwardly extending pick up tongue 115 is adapted to protrude inwardly through the openings in the cam plate and brackets protruding into the inner loop of the end clip, as shown in FIGURE 7 in solid lines, which has been separated from the remainder of the clips by means of the divider 17 which prior to descent of the selector 13 has cut the adhesive bond between the two end clips.
The thus selected clip on gradual release of the manual pressure rises in the central slots 46, 47 of the brackets 44, 45 indicated in FIGURE 7 and upon ascent of the cam follower portions 113' and 114' over the camming surfaces 69, 70 of the cam plate 60 the inner loop of the clip is extended outwardly of the outside loop thereof to be disposed over and grasp one side of papers disposed in the retaining means or magazine 14, the outer loop being disposed on the opposite side of said papers, and due to the enlargement of the slot 47 in its upper portion, the clip is free to leave such slot upon final ascent and is secured to the papers.
In the downward movement of the slide piece, there is lost motion provided between the manually operable means 15 and the divider 17 to accommodate differences or lack of uniformity in the clips as well as to provide for the sequential operation of the clip divider and pick up member, the clip pick up member being positioned above the cutting edges of the cutter during a portion of its descent so that the beveled cutting edges of the cutter are first brought into a position between a pair of first presented clips of the block of clips to separate the outermost clip from the said block prior to its engagement by the clip pick up means. The lost motion connection is best seen in FIGURES 2 and 5 and further clarified by the details of FIGURES 8-10. The rearwardly projecting arms 94, 95 of the cutting means 17 have vertical portions 96 provided with rearwardly projecting lower and upper lugs 98 and 99, respectively. The laterally projecting ears 86 of the manually operable means 15 project loosely between said lugs 98 and 99 whereby said means 15 can move upwardly and downwardly to a limited degree without moving said cutting means 17.
It will be observed that in operation the papers are inserted vertically in the most convenient position within the paper retaining section of the dispenser; that the same rest on their lowermost edges on the shoulder portions 68 of the cam plate thus permitting evening in position; the clips are separated selected and placed in position with the inner loop on one side of a sheaf of papers and upon release of pressure the clip securely retains the papers and the papers are then easily removed by an upward movement.
