6 Claims.
The present invention relates to stapler or tacking devices. In particular, the present invention relates to a stapler of the hand-grip type, which may be held entirely within one hand for Vactuation, either by forcing one component against the other, or by resting one component thereof on a suitable support and hand-forcing the other component thereagainst.
The main object of the present invention is the provision of a device of the character `described wherein the staple advancing pusher is automatically locked in retracted position during the staple loading operation so as not to interfere with the staple loading, and is automatically released for advancing pressure against lthe staples lwhen the loading thereof is completed.
Still another obfect of the Vinvention `is the provision of a device of the character described including a staple pusher, which lstaple vpusher is normally slidable lflatly along a suitable support, but, on retraction .to permit staple loading, is rockable from the flat position and locked out of engagement with the staples.
Another object of the present invention is the provision of a hand stapler of the -character described which has substantially increased staple -capacity in relation to length.
Other and further objects of the present invention will in part be obvious, 'and in part specifically pointed out in the following description of an illustrative embodiment thereof.
In the drawings annexed hereto and forming .a part hereof,

, thereof for pivoting, as at 36.
The devi-ce of the present invention, indicated generally by reference numeral I0, comprises a base plate I2,.a cover 3D including a cover guide 50, and a staple magazine assembly, all of which elements are pivotally pinned together at one end thereof.
Base plate I2 comprises an elongated member having an anvil I4 secured to its forward end as by rivets I6., I6.. Anvil I4 may be fixed to base I2 as shown, but within the present invention may ybe shiftable lengthwise of base I2 and may have more than one set of staple guide grooves, as I 8, I8, to bend the staple legs inwardly or outwardly as desired, this being conventional in the art. The sides of base I2 are bent upwardly progressively from the front end 20 thereof towards the rear 22, to form - side walls 24, 24 of increasing height, walls .24, 24 .being extended rearwardly past end 22 .as at 26, 2-6, the extensions being transversely apertured .as vat .28, 2'8, .for pivoting purposes.
Cover Suis substantially as Vlong as base I2, and is provided with a downwardly depending skirt wall 32, Y32., transversely apertured at the rear 34 A drive member 38 of ,flat spring steel is provided and secured `to the underside of cover 30 as by rivets-4G, 40, member .3,8 having an integral downwardly projecting staple driver component 4,2 at the forward end thereof `and an .integral rearwardly and downwardly angled spring arm 44 .at the rear thereof.
The staple magazine assembly includes housing 64, staple support trackway 66, .staple pusher 168 and a staple feed yspring 1l), the latter `being mounted .about fa locating 4and guide rod 12 trapped Within strackway I66, lengthwise thereof.
As seen in Figure '7, base I2, housing 64, cover guide 50 and cover 30 are pivotally connected at their rear ends, as by a rivet 84 passing through registering apertures 28, 82, 58 and 36, the respective elements being nested as shown. A base spring leaf 86 is secured to the upper surface of base I2 by rivets 88, 88, the free end 90 thereof angled rearwardly and upwardly bears against the underside of housing floor 14 to resist, to some degree, movement of housing 64 towards base I2. Within housing 64 is disposed the staple support trackway 66, including pusher 68 of the present invention.
being so spaced apart as to permit conventionally7 sized staples to rest llatly thereontop, with the staple legs extended downwardly. As seen in Figures 4, and 6. the overall height of walls 94, 94 and flanges 96, 96 is such as to equal the length of conventional staple legs, as 98, the base |00 of the staples resting flatly atop flanges 96, 96. Floor 14 is cut away behind front wall 18, as at |02, to permit passages of staples therethrough under the influence of staple driver 42. Floor 92 is bent up adjacent the front end thereof as at 04, and the rear end thereof is bent up as at |05, the bendings defining parallel lugs at opposite ends of the trackways and having aligned transverse apertures |08, ||0 therethrough respectively. Trackway 66 is disposed within housing 64, atop floor 14, positioned so that the front end of the flanged portion is spaced one staples thickness from the inner aspect of housing wall 18, as indicated at |I2; the spacing at ||2 being in vertical alignment with opening |02 in the floor of housing 64.
Referring to Figure 8, it will be seen that flanges 96, 96 are notched as at |30, |30, near the rear end thereof. In assembling trackway 66, pusher 68 is slid over flanges or rails 96, 96 from the front thereof. The spring 10 is then threaded on rod 12, and the leading end of the rod passed through wing aperture |22 of pusher 68. The leading end of rod 12 is then passed through aperture |06 in lug |04, and the rear end of rod 12 p assed through aperture |I0 in lug |06. The projecting ends of rod 12 are then upsetras at |32, |32 to lock the parts together, and. the assembly is then secured, as by spot welding at |34 (see Figure 5) within housing 64 as above detailed.
To load a supply of staples onto trackway 66, within housing 64, the cover and guide assembly 60 is released from the engagement of lugs |40, I 40 in apertures 38, |38 (Figure 5) and swung away from housing 64, into the position of Figure 2, thereby exposing the interior of housing 64 and tr-ackway 66 therewithin. Pusher 68 is then slid rearwardly on trackway 66 by manual pressure against upstanding wing |20, until the pusher passes notches |30, |30, this rearward movement being limited by downturned flange portions 91, 91.y As fingers |24, |24 pass notches |30, |30, a tilting movement is developed on pusher 68 by compression cf spring 10, due to the location of the points of action, and the front end of the pusher tilts upwardly and ngers |24, |24 raised above the level of notches |30,
|30. Thus, on release of the moving force', fin# gers |24, |24 will be spring pressed against the forward edgesof notches |30, I 30, to hold the pusher 68 temporarily in that position and out of the way while a strip of staples is laid into housing 64 with the staple bodies |00, |09 lying flatly atop flanges 96, 96 and the staple legs 98, 98 projecting downwardly into the space between housing walls 16, 16 and flanges 96, 96. When the staple supply strip is thus positioned,
cover 30 and guide 50 are swung, as a unit, over As so' against andv onto housing 64. Pusher 68 is locked,
at the rear ofthe device, nearer the pivot point, and as it is contacted by the lower edges of guide side bars 52, 52, bearing against the top of pusher body II 4, it will be retiltedv to force fingers |24, I24 down below flanges 96, 96, and out of engagement therewith, whereupon the normal expansile biasing of spring 'Ill will shift the pusher against the rear staple in the supply strip, forcing the 'staple strip forwardly until the first staple in the strip is urged against the inner aspect of housing wall 18, over opening |02, and in line with staple driver 42, as in Figures l and 4. Lug IM serves as a stop to engage wing I I8 on the underside of pusher 68, limiting the forward movement thereof.
'Io operate the device to drive `a staple, cover 38 is forced downwardly towards v .and against base I2, against the normal biasing of spring leaf 90, pressing against the underside of housing 74. As spring 90 is overcome and flattened, cover 36, guide E) and housing 'i4 approach base I 2, at which time staple driver 42 moves downjward behind wall 'I8 and through the channel opening II2, separating the leading staple from the strip and driving samel against anvil I4.
The cover 30, guide 50, housing 54, trackway 56 and base 24 are all formed, as by stamping or otherwise of fiat sheet steel. The parts are heat treated at locations where wear occurs, and the device, as a whole, may be brightly plated or otherwise treated to enhance its appearance.
With my trackway and pusher arrangement, it will be seen that the staple holding capacity of my device is substantially that of the length of the trackway, less the length of the pusher. The particular coil spring shown, which has a plurality of coils of different diameters, while operating quite well with my device, is not essential thereto, same being the subject of a copending patent application Serial No. 83,750, led March 16, 1949, which matured into Patent No. 2,528,444 on October 31, 1950, and which was reissued under No. Re. 23,349, dated March 27, 1951. As will be readily appreciated from the foregoing, my device may also be used to drive staples without deforming the legs thereof, as the cover 3U, guide 50, and housing assembly I4 may be swung away from and used independently of base I2. In view of the relatively small size it is possible to achieve with a stapler of the present invention, a chain C may, if desired, be linked to the end thereof, as in Figure 1, so that it can be hung on a suitable support.
Having now described my invention, what I claim and desire to secure by Letters Patent is: Y
l. In a stapling machine including a base, an upper member of inverted channel shape, and a staple driver blade projecting downwardly therefrom at the front end thereof, with the rear end of the upper member being pivotally supported on the base; the improvements comprising a lower member of channel shape open at the top and forming a magazine for staples, the rear end of the lower member being pivotally supported at the rear end of the upper member; a means at the front end of the lower member for retaining the staples; a staple supporting trackway disposed within the lower member and spaced from the sides thereof and from the staple retaining means; a pusher movably supported on the trackway for engaging the staples; yieldable means in the magazine to urge the pusher forward for moving the staples towards the retaining means; inwardly directed fingers on the opposite sides of the pusher'extending towards each other, the
trackway at the rear thereof having detentsifor the fingers, means for tilting the pusher with its front end upwards of the trackway upon manual retraction thereof for engaging the detents by the ngers thereby preventing the pusher from being moved by the urging means; a driver guide' between the cover and the upper member and interengaged with the cover to pivot therewith,"
