21 (Ilaims. (Cl. 242-193) The subject matter of this invention is directed to a disposable cartridge adapted to be removably received in a stapling machine or tacker and adapted to utilize a flexible and resilient staple element belt adapted to be formed into a roll or pack comprising juxtapositioned and substantially rectilinear wire elements. The object of the invention resides in the provision of a novel cartridge having a container for supporting the roll or pack and provided with an opening for issuing the foremost staple element strip of the belt out of the container for cooperating with slidably and swingably retained feeding means carried by the container outside thereof for moving the strip automatically and intermittently away from the opening and to operating parts of the stapling machine or tacker. Another object resides in the provision of a disposable cartridge wherein the feeding means carried by the container comprises spaced swingable and slidable spaced pawls and resilient means in the form of a bent loop carried by the pawls and cooperating with the container for normally urging the pawls away from the opening of the container through which the strip is issued. More specifically, another object resides in the provision of tooth means on the pawls cooperating with resilient fingers depending from the resilient loop for receiving and straddling the longitudinal margins of the strip and for initially idly shifting rearwardly relative to the strip on the application of pressure on the tooth means in a direction towards the opening to energize the loop and to subsequently grip the strip upon removal of pressure on the tooth means to automatically shift the strip in a direction away from the container. Particularly another object is to form the resilient and bent loop with spaced front legs and with spaced rear legs diverged from the front legs from which the resilient fingers depend and which are fixed to the pawls while the rear legs are interconnected by bridge means adapted to abut the container, the arrangement being such that the front and rear legs are normally appreciably diverged from each other to maintain the movable feeding means in a normal foremost position. More particularly, another object resides in interconnecting the upper portions of the front and rear legs of the resilient loop with externally convexed and internally concaved portions to maintain the front and rear legs in a normal diverged or biased relation. Another object resides in providing spaced rails extending from the container for linearly and slidably guiding the staple strip away from the container. Another object resides in the provision of stop means on the container to limit its insertion into a stapling machine or tacker. Another object is to provide an unobstructed passageway between the rails to receive and permit displacement of the spaced resilient fingers and tooth means in a direction towards or away from the container.
To these ends the present invention broadly consists in providing a disposable cartridge adapted to be removably received in stapling machines or tackers and adapted to utilize a flexible staple element belt adapted to be formed into a pack and having juxtapositioned and substantially rectilinear elements; characterized in that, said cartridge comprises a container for holding said pack and having an opening to issue a strip of said belt out of said container, feeding means for shifting said strip away from said opening, and means carried by said container for movably holding said feeding means to permit displacement of the latter relative to the container.
In order that the invention may be more clearly understood and readily carried into effect, the same will now be described more fully with reference to the accompanying drawings in Which:
FIG. 1 is a perspective view of the staple element belt carrying cartridge illustrating the swingable and slidable feeding means straddling the front part of the staple element strip of the belt.
FIG. 2 is a perspective view of the staple element roll or pack adapted to be housed by the container of the cartridge.
FIG. 3 is an exploded and perspective view of the container and its rails, and the feeding means which comprises the bent U-shaped resilient means and the spaced pawls to which the bent resilient means is secured when the parts are assembled.
FIG. 4 is a fragmentary perspective view of the cartridge carrying the swingable and slidable pawls to which the front legs of the looped resilient means are attached.
FIG. 5 is an enlarged horizontal transverse sectional view of the container on the line 5-5 of FIG. 1 illustrating the inner rabbeted faces of the companion sections of the container.
FIG. 6 is an enlarged side elevational view on the line 66 of FIG. 2, and
FIG. 7 illustrates a fragmentary bottom view of the disposable cartridge.
In the drawings, the elastic, flexible and foldable staple element belt SE is adapted to be closely wound upon itself in the form of roll or pack R (FIG. 2). Broadly speaking, this belt consists of rectilinear and juxtapositioned elements of suitable steel wire resiliently connected by the elastic coating 60 (FIG. 6) reinforced if desired by the relatively thin and elastic transparent film or tape. TP. R011 R is positioned within a split cartridge SBC which is preferably of a suitable plastic material and if desired transparent. As illustrated cartridge SBC comprises complementary parts generally indicated 61 and 62 defining a container having annular complementary rims 63 and 64 each interrupted at their lower parts by a gap or throat as 65 communicating with slots 67 and 66 defined by staple element guide rails 69 and 68 of the spaced wings 71 and 70. More specifically, rails 69 and 68 may be considered as constituted by spaced upper and lower parallel walls 73 and 72, the upper walls also merging with its associated annular rim to define apex means near throats 65, the latter characterizing an opening at the bottom of the container in the assembled relation of complementary parts 61 and 62. Integral with complementary parts 61 and 62 are the ears or arms 74 each having an overhanging fulcrum pin or post 76. Rims 63 and 64 have their inner margins appropriately rabbeted to provide reduced and interfitting portions 75 and 75 adapted to be glued together after insertion of the staple element roll R.
Also integral with complementary parts 61 and 62 of the container are the laterally extending rearwardly inclined fins or ribs FN having front flat faces 77 adapted to abut the stop faces 78 of spaced sides 79 of a tacker or stapling machine of the type disclosed in my copending patent application SN. 349,862, filed April 20, 1953, now Patent No. 2,938,212, out of which the present application has been divided.
Fulcrum posts 76 swingably carry a pair of pawls P each having an arm 80 merged at its lower end with a laterally arranged extension 81 each provided with a forwardly projecting finger 82 embodying at its forward end a rounded staple element gripping tooth or projection 83. Fingers 82 each include a rearwardly flared portion characterized also by downwardly and rearwardly extending cam face 84.
Each arm 80 of the pawls P is also provided with an inwardly turned and bent flange 85 having spaced studs 86 against which the front spaced legs 87 of the one piece U-shaped leaf spring or resilient means generally indicated 88 is appropriately welded in which case posts 86 will melt into its respective resilient legs 87 and associated leg support 85. Resilient means 88 is bent intermediate thereof to form a loop and has its rear portion 89 defining spaced rear legs interconnected by bridge 90 adapted to abut the container of the disposable cartridge SBC. However, it should be observed that arms 80 of the pawls P each embody an elongated slot 91 fitting over a fulcrum post 76 of the complementary parts 61 and 62 of the cartridge. With front legs 87 of resilient means 88 welded to bent flanges 85 of the pawls P and the latter elfectively retained on posts 76 and with the rear part 89 of resilient means 88 abutting the complementary circular rims 63 and 64 the pawls P have a loose slidable and swingable connection with the cartridge.
Normally legs 87 of the U-shaped and bent spring 88 slope, that is, are biased downwardly and forwardly following the direction of the contour of flanges 85 of pawls P. Of importance it should be realized that front legs 87 of the U-shaped resilient means 88 are reduced at their lower ends to form terminal depending fingers 92 defining means in association with spaced tooth means or convexed projections 83 of the pawls P to shift idly relative to strip SE and in a direction towards throats 65 when cam surfaces 84 are pressed rearwardly, that is, towards the container by suitable means as disclosed in my copending patent application above referred to in which case, pawls P are slidably and swingably displaced rearwardly, causing front legs 87 to swing towards the rear legs or rear portion 89, or in other words, resilient means 88 is energized.
When pressure is removed from cam surfaces 84, that is, from fingers 82, legs 87 automatically retract, carrying forwardly with them swingable and slidable arms 80, that is, both the spaced spring fingers 92 and the spaced tooth means 83 which are spaced from fingers 92 and substantially in vertical alignment therewith now grip the staple element strip SE, consequently shifting the latter forwardly, that is, away from the container of the cartridge.
Coming now to the staple element cartridge SBC, the upper and lower walls 72 and 73 of the staple element strip guide rails 68 and 69 are each provided with a notch or gap 700. The lower walls 73 as well as the inner margins of rims 63 and 64 of the container parts 61 and 62 embody effective interfitting rabbeted faces 75 and 75'. Consequently in the assembled relation of container components 61 and 62, notches 700 of the latter define a passageway 701 between rails 68 and 69. Passageway 701 (FIG. 7) widens out towards the front ends of the spaced rails 68 and 69 to permit reception and movement of the feeding means, and particularly movement of the spaced resilient fingers 92 and the tooth means 83 between the rails.
The cartridge SBC permanently, swingably and slidably carries the staple element strip feeding means in the form of spring controlled and spaced pawls P, and rearward displacement of the pawls are limited by stop faces 260 of arms 74. Also the aligned staple guide rails 68 and 69 which are integral with container components 64 and 63 of the cartridge, straddle staple element strip SE. With pawls P swingably and slidably connected to upper arms 74, the rear intermediate part 89 of the U-shaped and looped resilient means 88 bears against the companion rims 63 and 64 of the container while the front spaced legs 87 are appreciably diverged fiom the spaced legs of the rear portion 89, at which time swingable and slidable pawls P are in their foremost position and against stop faces 280 on upper arms 74.
Various changes may be made in details of construction and arrangement of parts without departing from the spirit of the invention or sacrificing any of the advantages thereby inherent therein.
