Patented Sept. 9, 1947 UNITED STATES PATENT OFFICE 3 Claims.
My invention relates to stapling machines and has particular reference to machines for stapling together sheets of paper or similar material, with or 'without clinching the ends of the staples.
My invention has for its object to provide a stapling machine of a light portable type which can be economically manufactured and conveniently used for various types of work such as stapling sheets of paper or for driving staples into various materials without clinching the ends of the staples.
My stapling machine is provided with a magazine for the staples, the staples being urged toward the operating end of the magazine by a slide engaged by a spring, The slide is arranged to be locked in an inoperative position for refilling the magazine with the staples. l. also provide means for automatically releasing the slide when the magazine is placed in an operative position in the machine.
Another object of my invention is to provide means to firmly retain the staples in the magazine so as to prevent their buckling or displacement when the slide and spring are quickly released.
Still another object of my invention is to provide means to yieldably retain the magazine portion of the machine in an operative relationship With the main body of the machine and to ren lease the magazine from the body for refilling,` the magazine with the staples.
My invention is more fully described in the accompanying specification and drawings in which- Fig. 1 is a sectional elevational view of my machine in an inoperative position, showing the slide for the staples locked in an inoperative position;
Fig. 2 is a similar 'view of the machine in an operative position with the slide released;
Fig. 3 is a rear end view of the machine;
Fig. 4 is a sectional view taken on the line [and of Fig. l;
Fig. 5 is a front end view of the machine;
Fig. 6 is a sectional View taken on the line 6-6 of Fig. l;
Fig. 7 is a top plan view of the magazine;
Fig, 8 is a top plan View of the spring for the cover of the magazine;
Fig. 9 is a bottom plan view of the spring cover of the magazine. Fig. l0 is a sectional eleva- 4tionnal view of the device showing the upper portion in a raised position.
My stapling machine consists of a base plate I having raised side portions 2 at the rear with holes 3 for a pin 4 pivotally supporting a body 5. The later is of an inverted channel or U- shaped section and is provided with a handle 'I at the front end. A magazine 8 for staples 9 is of a channel or U-shaped section andAis provided with holes in the rear ends of the 'side walls for a pin lil passing also through corresponding holes in the side walls of the base plate I, The magazine has end Walls I I, I2 with holes for the ends of a rod I5. A helical spring I6 is placed on the rod back of a slide II. The slide has end walls I8, I9` with holes 20, `2| for the rod I5. The diameter oi the holes is larger than the diameter of the rod so that the slide can be I noved up or down on the rod. The front ends of the side walls of the slide are provided with lugs 22 (Figs. l and 6) which can be placed in slots 23 in the bottom wall of the magazine by depression the front end of the slide as shown in Fig. l for locking the slide in an inoperative position with the spring I5. The staples are then relieved from the spring pressure and can be replaced in the magazine. The slide in this position assumes a tilted position with its rear end raised above the level of the upper edges of thevside walls of the magazine, under a raised portion 25 of a resilient spring cover 26 of the magazine. The rear end 21 of the spring cover is bent downwards and is placed between the pin I0 and the rear end wall I l. The iront portion of the spring cover is provided with depending side cheeks 28, frictionally engaging the sides of the magazine. The cheeks are provided with inwardly extending projections 29 engaging corresponding depressions 30 on the side walls. The depressions 3i! `are' elongatedtowards the front end of the magazine for allowing a certain sliding movement of the spring cover on the magazine. The front portion of the spring cover 26 is also provided with raised lips 3l (Figs. 1 and 6) slidably en gaging the front end of a leaf spring 32. The latter is attached to the upper Wall of the body 5 by a rivet 33. The rear end of the spring 32 is bent downwards at 3A and rests on the upper edges of raised portions 2 of the base plate I`. A lng 3,5 is also attached by the rivet 33 to the body 5 and engages the raised portion 25 of the cover `2E; as shown `in Fig. l. The lug depresses the raised portion 25 when the body 5 is moved down,- wards as shown in Fig. 2 thereby flattening the `spring cover 26 and depressing the rear end of the slide `I'I thereby releasing the lugs 22 from the holes 23 and allowing the `,slide to be `moved forward under action of the spring I 6 for moving the staples 9 towards the front end of the magazine, until they abut the bent-over ends 3l of the side walls of the magazine, The bent-over ends of the walls are spaced from the front wall I2 for allowing the foremost staple to be positioned in a clearance between the wall I 2 and the bentover ends 3l. An opening 31' is provided in a clearance between the walls 31 and I2. The body 5 is provided with a driver plate 38 at the front end adapted to enter the clearance between the wall l2 and the bent-over ends 3'! for driving the foremost staple out against the upper side of the base plate l. The latter is provided with a raised pad 40 having depressions 4l for clinching the ends of the staple.
The rear ends of the walls of the magazine 8 are provided with recesses 4| for a pin 42 slidably supported in elongated slots 43 in the walls of the body 5. A leaf spring 44 is attached at one end Iby the rivet 33 to upper plate of the body 5, the lower end of the spring 44 engaging the sliding pin 42 and urging the same into the recesses 4i. The pin 42, under pressure of the spring 44, tends to raise the front end of the magazine 8, assisting in this respect the spring 32. gaged from the clamp 28, the magazine and the body 5 being then forced apart into a position shown in Fig. 10 with the magazine exposed. The slide 1 is moved rearward and locked in this position as shown in Fig. 1. Staples can be then placed in the magazine. The slide 'l is released by moving the body 5 and magazine 8 into mutual engagement until the clamp 28 snaps in its place on the magazine. v
