COMBINATION BINDING MACHINE.

Application filed June 9, 1921. Serial No. 476,250. g

My invention relates to combination bindthrough the machine,'the body portion of ing machines capable of being employed for the strips as distinguished from the prongs, stapling or securingseveral sheets or layers engaging the upper face of the knife to be of paper or other material to each other. 7 supported thereby lnstead of having the 5 One of the objects of the invention is the strip resting upon the ends of the prongs provision of such a machine which is proof the staples as in the machines as now vided with a staple securing and straighten constructed.

vertically in the guideway ing the positions assumed by the various parts ofthe machine when the plunger of the machine and the staple straightenmg and securing means have been moved to their extreme downward position;

Fig. at is a plan view of the bottom of the housing of the machine; and

Fig. 5 is a front elevationof the staple securing and straightening means.

Referring now to the drawings in detail, 1 designates the base of my pmachine which. base may be of any desired shape and is provided with pads 2. Mounted upon the base 1 is an anvil 3 which is adapted to be engaged by the ends of the prongs of the staples during the clinching operation. Mounted upon the b-ase 1 and preferably, though not necessarily, pivoted thereto is a housing 4:, which in the present instance is shown pivoted to the base 1 at 5.

The housing immediately above the anvil is provided with a guideway 6 for the plun ger 7 of the machine and with a guideway 8 for the staple securing and straightening member 9 hereinafter to be referred to in de- The plunger 7 carries a coil spring 10, the lower end of which is adapted to engage the upper part 11 of the housing, the upper end of this spring being engaged by a cap 12 by which the machine is manipulated.

The staple securing and straightening member 9 already referred .to comprises a comparatively thin plate provided with

legs

13 and 14, which plate isadapted to slide 8 in the housing of the machine. The upper part of the staple securing and straightening member 9 is provided with an elongated slot 15 through which a'small screw 16 is adapted to pass and which screw is secured to the plunof the machine. It isto be understood, however, that the slot 15 just referred to is of larger dimensions than the screw 16 so that the staple securing and straightening member may have movement relatively to the plunger: '7. The upper part of the staple securing and straightening member 9 is provided with laterally extending lugs 17 and one end of a coil spring 18 which is carried within the plunger spring 10 already referred to is adapted to rest upon this end of the staple securing and straightening means, the other end being engaged byv the cap 12 already referred to. r

From the description thus far given it will be seen that I have provided a plunger and a staple securing andstraightening member in a housing, these two members, that is to say the plunger and the staple securing and straightening member, being so mounted as to be reciprocated vertically in the housing of the machine, the plunger and the staple securing and straightening member having movement parallel to each other and being movable at certam times independently of each other.

This arrangement is provided so that the staple securing and straightening member may move down to staple-securing position before the plunger reaches that point in its travel where the staple is out off and the forward end of the strip being fed through the machine. I

It will be seen also that I have provided springs for each of these members so that they will automatically return to their initial posit-ion, that is to say, to the position shown in Fig. 1.

Secured to the housing of themachine in any suitable manner is a member which I shall hereinafter term a knife designated 19. This member is adapted to receive a strip of staples which are fed into the machine from the rear thereof, that is to say from the right-hand end as viewed in Fig. 1 and to be engaged by the body portion of the strip of staples as distinguished from'the ends of the prongs of the staples, and to cooperate with the plunger 7 and the staple securing and straightening member. 9 so that when the parts are moved to the position shown in Fig. 2 for example or just slightly further, the forward staple of the strip will be out off by the plunger, the staple cut off being held up to this time in position for the cutting operation by the staple securing and straightening member and as will hereinafter be pointed out, being then straightened and,-so to speak guided during the driving and clinching of the staple.

The plunger 7 is which isadaptel to be straddled by the legs 13 and 1 1 of the staple securing and straightening member, this lever 21, forming part of what I shall hereinafter term a combined feeding means and back-stop. This lever 21 is provided with a pair of

lugs

22 and 28 between which the lug'20 is adapted which lugs are at times engaged by the lug 20 so as to rock the lever 21 about its pivot. Secured to one arm of the lever 21 is another lever 2a, the

levers

21 and 24 together constituting a combined feeding means and backstop for the staple. The lever 2 1- at its rear end is provided with a spring 25 passing abouta pin 26, the other end of the spring cooperating with the pressure lever 27 to be hereinafter referred tomore in detail.

The front end of the lever to engage the strip of staples at a point between adjacent prongs thereof and when the strip is in position forthe cutting operation the front end 28 of the lever 24 will be in engagement with the strip of staples between the third .and fourth staples of the strip. YVith the front end 28 of the lever 24 in this position rearward movement of the strip of staples is prevented.

The pressure lever 27 already referred to is pivoted in the housing of the machine at provided with a lug 2O lug cooperating with a.

to be reciprocated and 2 1 is adapted 29 and cooperates with the spring 25 already referred to, to merely hold the strip of staples down against the top of the knife 19. By reason of the provision of the combined feeding means and back-stop already described, the pressure plate 27 is free of teeth.

The locking member or lever 30 is pivoted at 31 to the housing of the machine and is adapted to engage the rear end of the pres sure lever 27 and in the position shown in Fig. 1 the parts are in position for automatic operation of the machine. If it be desired, however, to remove a stripof staples from the machine for any reason whatsoever, or to substitute a new strip of staples or to operate the machine'by hand as distinguished from automatic operation of the machine, it is merely necessary to swing the locking lever 30 to its extreme left-hand position, which movement of this lever will lift the pressure plate 27 and also the lever 24 so as to permit of an unobstructed movement of the strip of staples for any reason whatsoever.

In operation the locking lever 30 is preferably moved to its extreme left-hand position to raise the pressure lever 27 and the lever 24 upwardly and a strip of staples 32 is then fed into the machine with the prongs straddling the knife ,19 and the body portion of the strip resting upon the upper surface of the knife, the strip being moved into the machine until the front end thereof cngages'the side 33 of the guide 6 for the plunger 7. The locking lever 30 is then moved to the position shown in Fig. 1.

It is to be understood, however, that if desired the lever 30 may be left in the position shown in Fig. 1 in loading the machine as the strip of staples may be stiff enough to permit of the strip being forced beneath the pressure plate 27 to the position above described. Several sheets of paper or other material which itis desired to staple 'may then be inserted upon the anvil 3, the frame 4' of the machine being rocked slightly about the pivot 5 for this purpose. The cap 12 is then moved downwardly to carry the plunger 7 and the staple securing and straightening member downwardly also.

he staple securing and straightening member 9 at the beginning of this movement is slightly in advance of the plunger 7 so that the legs of the member 9 will enter between prongs of the strip before the moved downwardly snfficiently far to cut off 11 this I am enabled to the forward staple. By securely hold my staple in position for the cutting operation. As the plunger 7 and the member 9 continue their downward movement the plunger Wlll cut'the forward staple .from the strip and as soon as this forward staple is cut off it will be forced by right as viewed in Fig. '1 and this the front end 28 of the l by the the staple from the strip member 9 effectually prevents any forcmg'of the staple out of 1 ts proper position or any bending of the in proper position so that the staple ways be driven will al home and clinched. This prevents clogging of the machine for it will be obvious that should a staple be bent in being cut off and driven through the paper, that the machine will be clogged and that the papers or other material will be improperly stapled. Should the machine become clogged it would necessitate the removal of the strip of staples and waste of the entire strip. 7

Still referring to the operation of my machine, -it will be seen that as moves downwardly due to and finally it will engage the lower lug 28 on the lever 21 forming part of the combined feeding meansand back-stop above referred to. his engagement of the two lugs will cause the lever 21 to be rocked about its pivot to carry the lever 24 to the of the lever 24 takes place before the first staple of the strip is cut oil. The lever 24 is moved to the right or rearwardly until ever engages a strip the third and fourth and will remain in this the remainder of the downward movement of the plunger 7 and the staple securing and straightening member 9. It will be seen, therefore, that not only is the strip of staples securely held during the cutting operation and that-not only is the staple cut off properly straightd and guided, but after the forward staple is cut off rearward movement of the strip of staples is also prevented; After the plunger 7 and the staple securing straightening member limit of their movement downwardly, that in Fig. l. movement of the plunger 7 and the staple securing and straightening means 9, the lug 20 carried by thev plunger will engage the lug 22 of the lever 2l-to rock the lever in' movement ward staple of wall of the guide 33 for the. plunger.

the opposite direction to which it was rocked on downward movement of the plunger. This movement of the lever 21 will carry the lever 2e forwardly, that is to the left, as viewed in Fig. 1 and inasmuch as the front end 28 of this lever is in engagement with the strip of staples between the third and fourth staples thereof, the strip will be fed forwardly until the forthe strip will engage the The parts are now in position for another Sta-- pling operation.

From the foregoing it will be seen that I have provided a combination binding machine wherein means have been provided having movement parallel with the plunger of the machine for securing and straightening staples during the staplingoperation so that clogging of the machine is prevented and so that a proper driving and clinching of the staples is assured.

It will be seen also that I have provided a combined back-stop and feeding means for the strip of staples whereby the strip of staples will always be fed forward properly and whereby rearward movement of the strip is effectually prevented.

It will be seen also that I have provided an improved pressure plate which is adapted to maintain the body portion of the. strip of staples in engagement with the knife and which pressure plate by reason of my improved feeding means and back-stop is free of teeth. 7

It will be seen furthermore that if desired I may raise the pressure plate and combined feeding means and back-stop out of their normal position so as to operate the machine by hand if desired, this being desirable at times when it or desirable to employ longer or shorter pronged staples than the machine happens to be loaded with.

It will be seen also thatmy machine is of operating with. staples, the

capable. prongs of which may be of varying lengths, thereby avoiding the necessity ofmanufacturing or furnishing a specific length of prong that may be used.

WVhile I have described a specific em-- bodiment of my invention it is to be under stood that changes may be made in the details thereof without departing from the spirit and scope of my invention.
