Daniela — 31 May Works okay I bought one as a gift and one for myself. Rachel — 05 March Marina — 01 Dec. Good for up to 4 pages There is a trick to it - place the stapler on the desk, insert the pages and punch down firmly in one go.

However, to provide storage for a reasonable number of staples requires a much longer stapler, approximately 50 staples requiring one inch of length, although this depends on the size and also the strength, that is the metal dimensions of the staples. The present invention provides a stapler which does not require staples. It cuts out, bends, and reinserts a tongue of paper so as to fasten several sheets together. There are no separate staples, no anvil to bend staples, no reloading or refilling is required.

Unfastening is very simple and easy and does not produce loose staples. Broadly, a stapler in accordance with the present invention has a first cutter which cuts a tongue in each of the superposed sheets of paper, the tongues being bent down.

Simultaneously with the cutting of the tongue, a slot is cut through the paper sheets, aligned with but spaced from the tongues, being spaced from the bends of the tongue.

A deflecting finger pivots round and deflects the tongues round. The free ends of the tongues are then moved up through the slot. A simple, neat, fastening is formed. It can readily be unfastened by pulling the tongues back out of the slot. In accordance with the invention, there is provided a stapleless stapling apparatus having a base; a housing mounted on said base; a slot formed between a bottom part of said housing and said base for reception of sheets of paper; a handle; a plunger reciprocally mounted in said housing for movement by said handle; a punch and a chisel reciprocally mounted in said housing for movement by said plunger, said punch having a hollow U-shaped cross-section adapted to cut a tongue-shaped section from said sheets; a bending member pivotally mounted in said punch, said bending member including means for engaging on the bottom surface of said housing to pivot the bending member; the arrangement such that initial actuation of said handle pushes down said punch and said chisel to cut tongue-shaped sections from said sheet and cut a slot in said sheets, continued actuating of the handle pivoting said bending member to bend up said tongue for insertion into the slot cut by said chisel.

In one form of the invention, the handle and plunger move vertically, in the housing, direct pressure being applied to the handle and plunger. In another form, the handle is elongate, extending over the housing and plunger and is pivotally mounted at one end.

Pressure on the other end of the handle pivots the handle down, moving the plunger down. In accordance with this invention, the tongue-shaped section has an enlarged leading end which is most desirably in the form of an arrow-head configuration, although other like configurations may be employed for that purpose. Another preferred aspect of the invention is where the apparatus includes a slot extending through said chisel, adjacent the free end thereof, said tongue shaped sections adapted to be inserted into the slot and chisel by said bending member, with retraction of said chisel being adapted to pull said tongue shaped sections through said slot cut in the sheets by said chisel.

A still further preferred form is where the apparatus includes a reciprocating member in said housing mounted on an inner end of said plunger, said punch and said chisel mounted on said reciprocating member. Another preferred embodiment is where said bending member comprising an arcuate member, the curved end portion of the arcuate member bending said tongue-shaped sections.

In a preferred embodiment is shown an apparatus, wherein the enlarged leading end of said punch has a projection on at least one side to form a projection on the corresponding side of the tongue shaped sections.

A further preferred embodiment shows a punch having a projection on each side adjacent its closed end, to form a projection on each side of each tongue-shaped section adjacent its free end. A further preferred embodiment has a bending member having a curved end portion when viewed from the side, said curved end portion having an arcuate cross-section, with the concave surface facing inward, whereby the free ends of the tongue-shaped sections are formed into a trough like form as they are pushed by said bending member.

The invention will be readily understood by the following description of certain embodiments by way of example, in conjunction with the accompanying drawings in which:. As illustrated in FIGS. At what can be considered as the front, the housing 11 is recessed to provide a slot or channel 12 for reception of the sheets to be fastened together.

Located exteriorly of the housing is a handle or actuator A plunger 15 is slidably mounted in and through the top of the housing 11, a compression spring 16 extends between the top of the housing and a spring retaining cap 17 on the plunger; the handle 13 being connected to the plunger 15 at the cap If desired, the cap 17 could be enlarged to function as a handle, using a pivoting arrangement at an end of the handle.

The plunger 15 is attached at its lower end to a reciprocating member 18 which carries a hollow three sided punch or shear 19 and a chisel or flat cutter A stop member 21 is also mounted on member Also, they were rather expensive and required more elbow grease than traditional staplers. With an improved blade design, some models of Harinacs were capable of stapling 10 sheets at a time.

Earlier this year, special staplers were released with less resistance for fastening easy enough for children. With their inherent weaknesses eliminated, there was nothing but benefits to using these revolutionary devices. With no staples money is clearly saved and stacks of paper can be easily recycled. No more having to pull back that high tension spring and fumbling with one hand to load the staples which then fall in sideways.
