8 Claims. (Cl. 1 3) This invention relates to stapling machines and morerparticularly to the type known as a desk stapler.
It-has for its objects to provide a greatly improved and simplified stapler in which the mere act of opening the cover automatically retracts thestaple pusher means and fullyexposes the staple magazine so that a new supply of staples may be placed therein. f
Another object is to provide a means of retracting a staple pusher which is positive and trouble-free, and still another object is t-o provide a stapling machine of greater durability which is less costly to manufacture.
Other objects and advantages will become ap parent from a consideration of the following detailed description taken in connection with the accompanying drawings wherein a preferred embodiment of my invention is shown. However, it will be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the appended claims.
Figure l is a perspective view of the present stapler;
Fig. 2 is a central longitudinal sectional view; and
Fig. 3 is a transverse sectional view, taken on line 3-3 of Fig. 2. f
Referring now with greater particularity to the drawings, the stapler of this invention comprises three principal units, namely a base B; `a magazine (staple) arm A and a cover C. The base B may be fitted with rubber feet I6 to prevent scratching of table and desk surfaces. A pair of spaced parallel ears I I extend upwardly from the base B near the vrear end thereof, and an anvil I2 of the usual type adapted for staple clinching is seated upon the base near the forward end there- The arm A which is in the form of an upwardly facing channel having a bottom I5, sides I6, and a front end wall Il, is pivotally carried between the ears I I by a pin I8. Adjacent the front wall I1 is a vertical transverse slot I9 extending through the bottom I5.
A-staple rail R in the form of an upwardly facing channel with vertical walls 23 each having at its top an inturned flange 24, is positioned between andspaced away from the sides I6 `of the arm A and'extends from the slot I9 rearwardly for substantially the full length of the arm. A rod 25 extends longitudinally between the walls 23. The rearward end'of the rod 25 is formed into an eye which encircles the pin I8, and its front end terminates short ofthe slotIS.
There is also provided a staple pusher P in the form of an inverted U having a top 36, sides 3I, a .lug 32 depending from the top 36 between the sides 3 I ,and an upwardly projecting forwardly 2 facing hook 33. This pusher is arranged to ride upon the staple rail R with its sides 3| positioned between the rail walls 23 and the arm sides I6, and the depending lug 32 extended between the rail walls 23 and under the inturned flanges 24 so as to be conned thereby. An opening in the dependinglug 32 is adapted to slidingly receive the rod 25, and a spring 35 encircling the rod 25 serves to urge the staple pusher forwardly in a manner common to the staple art.
The cover C is in the form of a downwardly facing channel having sides 40, a front wall 4I, and
, a top 42 which slopes downwardly towards the rear. The cover is pivotally mounted on the pin I8 which extends between the ears vI I. A staple driver D is positioned adjacent the inside of the iront wall of the cover and in vertical alignment with the slot I9. This drivel' is alXedto the front side of a four-sided tubular post 46 which is arranged Yfor vertical movement within the r cover C. A knob 41 is mounted on top of the post.
A bracket 50 is secured between the sides 40 of the cover C medially of its ends, as shown in Fig. 2. Inserted in an opening in the bracket 50 is one end of a leaf spring 5I whose other end 52 engages the post 46 so that when the staple driver D is forced downwardly in response to pressure on the knob 41, the spring 5I exerts an upward tension which causes the staple driver to be raised following each stroke. The range of the staple driver is limited by a transverse pin 55 the ends of which'are affixed to the sides of the cover for extension through vertical slots 56 in the sides of the tubular post 46, thereby restricting vertical movement of the staple driver D to the length of the slots 56.
Amxed to the under side of the cover-top 42 and toward the rear thereof is a depending ear 60 to which is pivotally attached one end of an arm 6I which extends forwardly and downwardly to terminate in a downwardly and rearwardly facing hook 62 adapted for engagement with the forwardly facing hook 33 on the staple pusher. A spring 63 constantly urges the arm 6I downwardly. The arrangement is such that when the cover C is inrits normal closed posi- -tion the arm hook 62 will be adjacent the forward end of the staple rail R. When the cover is raised, the arm 6I automatically moves rearwardly, and in so doing the arm hook 62 engages the pusher hook 33 to move the pusher P rearwardly on the staple rail R as shown in dotted lines in Fig. 2. After a new supply of staples has been placed upon the now fully exposed staple rail, closing of the cover C automatically will cause the army 6I to move forwardly, thus disengaging itself from the staple pusher P which, in turn, resumes its normal function of pushing the staples toward the s-taple driver D.
Mounted on the front end wall I'I of the arm A is a spring latch Ill adapted to engage and retain the cover C in its closed position. A spring 1| near the rear of the cover C exerts an upward tension thereon.
To replenish the staple supply it is merely necessary to release the latch 'I after which the spring 1| will then automatically raise the cover C, and in so doing the arm hook 62 will engage the pusher hook 33 and move the pusher to the rear of the staple rail R. The operator then only has to place a new supply of staples on the rail, close the cover C, and the stapler is ready for use.
It will be observed from the foregoing description that my invention provides a particularly simple, compact and trouble-free staple pusher retraction means which operates automatically to expose the staple rail and hold the pusher in inoperative position during the time new staples are being inserted and automatically restores the pusher to operative position when desired.
It is also to be noted that the mechanism of my stapler is simple in construction, compactly arranged and so designed as to be capable of economical manufacture. The parts of the mechanism are designed for strength to insure long life and accessibility to aid in assembling the mechanism or removing the parts for repair or replacement.
The present embodiment is to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
