Abstract
Abstract A machine is provided for binding papers utilizing binding strips of the type wherein one strip has a series of studs with ratchet teeth thereon and a mating strip has a series of holes for engaging the ratchet teeth and a series of blocking elements for locking the teeth in place to provide a permanent binding. The device of the present invention cuts off any excess length of the studs after the binding operation and, in a preferred embodiment of the machine, includes a punching device for punching holes in a sheaf of paper prior to the binding operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
179 words
A machine for assembling a perforated sheaf of papers into a bound volume wherein the binding element utilized consists of a first backing member having a series of studs thereon, each stud having ratchet teeth and a second backing member having a series of mating holes with at least one ratchet tooth in each of said holes positioned to mate with a tooth on a stud inserted therein and with a blocking member for locking a ratchet tooth on each of the studs to a ratchet tooth in a hole, comprising in combination: a. means for supporting said second backing member while leaving said blocking means free of said supportIng means, b. means for corresponding said backing members together with the studs passing through the perforated sheaf of papers and into the holes whereby the ratchet teeth engage and hold the sheaf of papers in bound relationship, c. means for moving said blocking means into place to lock said ratchets together, and d. means for cutting off an excess length of said studs extending beyond said second backing means.
Claim 2
Dependent Claim
179 words
A machine for assembling a perforated sheaf of papers into a bound volume wherein the binding element utilized consists of a first backing member having a series of studs thereon, each stud having ratchet teeth and a second backing member having a series of mating holes with at least one ratchet tooth in each of said holes positioned to mate with a tooth on a stud inserted therein and with a blocking member for locking a ratchet tooth on each of the studs to a ratchet tooth in a hole, comprising in combination: a. means for supporting said second backing member while leaving said blocking means free of said supportIng means, b. means for corresponding said backing members together with the studs passing through the perforated sheaf of papers and into the holes whereby the ratchet teeth engage and hold the sheaf of papers in bound relationship, c. means for moving said blocking means into place to lock said ratchets together, and d. means for cutting off an excess length of said studs extending beyond said second backing means.
Claim 3
Dependent Claim
37 words
The machine of claim 1 wherein said blocking means include protrusions on the second backing strip located adjacent to each of said holes and the support means (a) comprises a series of fingers extending between said protrusions.
Claim 4
Dependent Claim
73 words
The machine of claim 2 wherein a platen biased upwardly is provided for receiving a sheaf of papers, said platen having a series of fingers extending therefrom to support the second backing member between said protrusions, said machine having a fixed member under said fingers whereby pressure on said platen with the extending fingers will overcome the bias, bringing the protrusions into contact with said fixed members, forcing said protrusions into said holes.
Claim 5
Dependent Claim
15 words
The machine of claim 3 wherein said platen with said extending fingers is biased upwardly.
Claim 6
Dependent Claim
43 words
The machine of claim 1 having a shaft passing through the machine with pinions thereon, and a ram is provided with mating rack teeth, whereby turning said shaft causes said ram to descend into contact with said backing members to compress the same.
Claim 7
Dependent Claim
63 words
The machine of claim 5 wherein said ram is divided into two transverse sections having interconnected release means whereby one of said sections can be released so that actuation of said shaft causes only one of said two sections to move into compressive relationship to said backing members and can be engaged whereby both sections move into compressive relationship to said backing members.
Claim 8
Dependent Claim
19 words
The machine of claim 3 having a second platen with punch means thereon for perforating a sheaf of paper.
Claim 9
Dependent Claim
17 words
The machine of claim 7 wherein a single shaft actuates the compression means and the punch means.
Claim 10
Dependent Claim
35 words
The machine of claim 1 wherein the cut off means comprises a plate having a plurality of cutting knives extending therefrom, and having a handle to move said knives into and out of cutting relationship.
Claim 11
Dependent Claim
32 words
The machine of claim 7 having two extending handles, namely a first handle to actuate the compression means and the punch means, and a second handle for actuating the cut off means.
