STAPLING MACHINE Filed June 14, 1950 //v VE/V 7-095 VV/T/VESsES: I 7. 4 E w Wj Patented Apr. 8, 1952 STAPLING MACHINE Jay N. Edmondson, Harry Poulos, and Clarence R. James, Columbus, Ohio Application June 14, 1950, Serial No. 167,952
3 Claims.
This invention is a novel mechanism constructed into a stapling machine to cause staples contained in a carrier or magazine to be driven into wood, rubber, steel, or other material, or against a die for the purpose of clamping material together, expressly designed to cause the staple to be driven and ejected either in a plane parallel to its original position, or to a position angular to its original position in the magazine.
The invention embodies novel means for selecting and causing ejection of the staple to either of the two previously mentioned positions. These means are illustrated in the accompanying drawing, in which we have shown the design which permits either parallel ejection of the staple, or ejection at ninety degrees to its original position. While we have shown therein a preferred embodiment, it is to be understood that the same is susceptible to modification and change, and comprehends other details, arrangements of parts, features and construction, without departing from the spirit of the invention.
In the drawings:
Fig. 1 is an illustration of the mechanism, partly in section to show details of construction, and staples indicated at X and Y to illustrate the possible ejected positions of the staples in this design.
Fig. 2 is a view in vertical cross-section.
Fig. 3 is a bottom View of the freely rotatable staple driving guide -way element.
Fig. 4 is a plan view of the cam cylinder.
Fig. 5 is a partial view in vertical cross-section taken longitudinally of Fig. l to illustrate the construction at the forward end of the magazine which is effective to provide a stop and a rear backing surface for the foremost staple of the staple strip.
Fig. 6 is an end view of the staple magazine.
Fig. 7 is a partial top view of the magazine.
Fig. 8 is a front view of the staple driving plunger.
Referring to Fig. 1, cam cylinder 3, which is not a part of plunger 5, contains a cam groove in which pin 4 travels. This groove is slotted through the cylinder to the opposite side, or may be on one side only. Pin 4 is pressed through a hole in plunger 5. Plunger 5 has a staple driving blade 5 secured to or a part of its end. This staple driving blade 6 is sized and shaped in such a manner that its bottom edge has the same contour as the top of the staple, and is thin enough to cause on y one staple to be pushed through the and channel of the magazine 2, and on through the rotatable staple guide-way member 1.
Operation of the stapler to eject staples to either position X or position Y is as follows? 1. To eject staples to position X, shown in Fig. 1, trigger 8',Fig. 4, is pulled outward to remove the end of the trigger from the slot l3 in cam cylinder 3, see Fig. 1. Depressing the handle 9 moves plunger 5 downward, which causes staple driving blade 6 of the plunger 5 to carry a staple I through the end-channel of magazine 2 and on through the rotatable staple driving guide-way member I. Cam cylinder 3 turns freely on plunger 5 since trigger 8 was disengaged from the slot 13 and as the drivingof the plunger continues through member 1 the staple will be driven as shown at X in Fig. 1.
2. To eject staples to position Y, shown in Fig. 1, trigger 8, Fig. 4, is pushed in to engage slot l3, Fig. 1. Depressing the handle 9 moves plunger 5 downward. Since cam cylinder 3 cannot rotate. pin 4 moving in the groove of cam cylinder 3 causes plunger 5 to rotate. This rotation of plunger 5 is delayed until a staple I and the staple driving blade 6 of the plunger 5 have completely engaged rotatable staple driving guide-way member I. This delay is accomplished by having the groove in cam cylinder 3 straight at each end, (top and bottom) for the necessary distance to delay rotation of plunger 5 on the downstroke, which in turn permits travel through the end channel of magazine 2. When the staple driving blade 6 of plunger 5 has passed into rotatable staple driving guide-way member I, the pin 4 has reached that section of the groove of cam cylinder 3 which will cause ninety degree rotation of 5, 6, and 1, after which pin 4 travels in the bottom straight section of the cam cylinder groove. Plunger 5 and staple driving blade 6, therefore, cease to rotate, causing l to remain stationary and the staple is ejected in position Y.
Spring M, Fig. 2, returns plunger '5 to its original starting position. As the plunger travels upward, there is no rotation of plunger 5 as long as pin 4 is in the straight section of the cam cylinder groove. Upon reaching the rotational section of the cam cylinder groove, the pin 4 causes the plunger 5 to rotate in the reverse direction ninety degrees, which in turn causes the staple driving blade 6- to rotate part 1 ninety degrees. This rotation places the staple-slot of part 1 parallel to and in line with the channel end of magazine 2, allowing thestaple driving blade 6 to proceed upward to its starting position above the top of the first staple I in the magaz ne. Rotation ceased immediately before the staple driving blade '6 passed into the end. channel of magvents the second'staple -in the magazine from be-- ing forced upward on the upstroke due to any small misalignment of parts.
Having thus disclosed the invention, weclaim: 1. In a staple driving assembly for a stapling machine, said assembly comprising-g a staple driving plunger, means mounting said plungerfor re ciprocating movement, a rotatable cylinder inwhich said plunger reciprocates; a'ma'gazine'for supporting a strip of staples with a foremost.
