3 Claims.
This invention relates to a stapling machine for securing together sheets of paper or similar material, and has particular reference to means for unloading the stapling machine in the event that the staples become jammed therein.
One of the objects of the present invention is to provide means for holding the staple slide that may be quickly and easily released to permit removal of the staple slide so that the machine may be unloaded.
Another object of the invention is to provide a simple, inexpensive latch that will securely hold the staple slide in the stapling machine and will not interfere with the regular operation of the stapling machine.
Other objects of the invention will become apparent upon reading the following description, taken in conjunction with the accompanying drawings, in which:
Figure l is a perspective view of a stapling machine embodying the invention;
Figure 2 is a perspective view of the stapling machine with the body portion turned about its hinge to show the latch holding the staple slide in position;
Figure 3 is a fragmentary end elevation showing the rear edge of the latch and staple slide;
Figure 4 is an enlarged fragmentary perspective view of the latch and stapling machine structure immediately adjacent the latch;
Figure 5 is a cross sectional view, taken along the line 5-5 of Figure 4;
Figure 6 is a View similar to Figure 4, showing the latch in open position and the staple slide partially retracted;
Figure 7 is a cross sectional view, taken along, the line 7-? of Figure 3, showing the bottom of the body portion of the stapling machine partly in section and partly in elevation;
Figure 8 is a fragmentary bottom elevational view showing the latch in open position and the staple slide partially retracted;
Figure 9 is a cross sectional view, taken along the line 9-9 of Figure 8.
Figure 10 is an enlarged fragmentary perspective view of the front end of the body portion in inverted position, showing the feed plate in engagement with the staples to advance them forwardly of the staple slide;
Figure 11 is an enlarged fragmentary bottom elevational view showing the feed plate after staples have been inserted into the stapling machine, but before the feed plate has been moved to the rear of the staples;
Figure 12 is a view similar to Figure 11 showat right angles from its opposite ing, in dotted lines, how the fingers of the Ieeu. plate are retracted when the feed plate is pushed past the newly inserted staples, and, in solid lines, the position of the feed plate fingers after the feed plate has been pushed past the newly inserted line of staples.
The stapling machine structure will not be specifically described, except as it pertains to the present invention, because the removable staple slide and the latching mechanism may be applied to almost any conventional stapling machine. Although the invention may be utilized in connection with the construction of many other stapling machines, it will be described specifically in connection with the stapling machine disclosed ,in my co-pending application filed February 15, 1949, under Serial No. 76,497, now
Patent No. 2,667,637.
In the drawings, the reference numeral 2 indicates the body portion of a stapling machine hinged to the base portion 3, as indicated at 4. The underside of the body portion is recessed, as indicated at 5 to, receive a staple slide 6. The front end of the recess is closed by the front wall i of the body portion. The side walls 8 of the body portion are each provided with a longitudinally extending recess 9. The staple slide is provided with a horizontal flange I0 projecting outwardly from each side, and these flanges fit in the recesses 9. The staple slide 6 is slid into the recess 5 from the rear.
A latch H is hinged to the rear end wall l2 of the staple slide in any suitable manner. As shown in Figure 9, an end extension l3 of the latch is passed through an aperture I4 in rear end wall 12 and is curled therearound to pivotally secure the latch to the, end wall of the staple slide. The latch has a pair of ears l5 depending edges. Each ear is provided with an undercut recess It for a purpose hereinafter described. Each side wall 8 is provided at its bottom with an inwardly extending flange I 7 having a vertical recess I S spaced a short distance from the rear end of the body portion and extending at right angles to the adjacent longitudinally extending recess 9. When the staple slide is positioned in the recess 5 with its front end 19 abutting the rear surface of the front wall I, and the latch H is swung about its hinge to overlie the rear end portion of the staple slide, the ears l5 will fit in recesses I8 and the undercut recess IE will engage the edge of side wall 8 adjacent each recess [8.
The interengagement of the ears IS with the edge of flange I! adjacent recess I8 is snug enough to hold the staple slide firmly in position. However, if it is desired to remove the staple slide to unload the staples 20, the latch may be easily lifted to disengage the cars from recesses l8, and the staple slide may be slid outwardly without difficulty. When the staple slide is removed, the staples may be easily removed from the machine.
A feed plate 2! is slidably mounted on a rod 22 which is secured within staple slide 6. The rod, which passes through rear end wall 12 and an ear 23 struck out of the staple slide, has a head 24 abutting wall l2 and has its other end held in ear 23 in any suitable manner. The feed plate comprises a pair of fingers 25 pivoted to a plate 23, as indicated at 21. Each finger projects rearwardly of plate 26 a slight distance, as indicated at 2B. These projecting ends 28 are engaged by a pressure plate 29 urged against them by a coiled spring 30 which encircles rod 22 and has one end bearing against the wall 12 and its other end against plate 29.
The force of spring 30 against the pressure plate constantly urges the feed plate forwardly relative to the staple slide, and also urges the fingers 25 outwardly about their pivots. The side walls 31 of the staple slide are each provided with an elongated slot 32 through which fingers 25 project when they are forced outwardly by spring 3.. In the normal position of the feed plate to the rear of staples 28 the fingers 25 engage the rearmost staple 20 and advance the line of staples towards the driving end of the machine, as shown in Figure and in the solid lines of Figure 12.
When the machine is almost empty the feed plate occupies the position shown in Figure 11, and a new line of staples is slid down on the staple slide while the stapling machine is held vertically with its driving end down. The staples and feed plate 29 then occupy the relative positions shown in Figure 11. While the machine is still held vertically the feed plate 25 is pushed upwardly manually against the action of spring 39. The staples are held on the staple slide by thumb pressure against the rearmost staple of the strip when the feed plate ispushed upwardly against the action of spring 30. The pressure of the staples on the outer edges of the fingers 25 causes the fingers to be retracted to a position as shown in dotted lines in Figure 12 so that the feed plate can bepushed towards the rear end of the machine. When the fingers 25 engage the end of slot 32 they are held in their inwardly compressed position by the side walls 3| of the staple slide, and the staples slide freely downwardly on the staple slide. When the rearmost staple has moved below the front edge of fingers 25 the feed plate is released, and spring 30 urges the feed plate downwardly to thereby advance the staples toward the driving end of the machine. The spring 30 exerts enough force against the plate 29 to force the fingers 25 outwardly into slots 32 as soon as the staples are positioned below the end of the slots and-the fingers are in register with the slots.
Although I have described a preferred embodiment of my invention in considerable detail, it
will be understood that the description thereof is intended to be illustrative, rather than restrictive, as many details may be modified or changed without departing from the invention. Accordingly, I do not desire to be restricted to the exact structure described, except as limited by the appended claims.
