Abstract
Abstract A binding machine having two articulated shells in the internal faces of which is formed a continuous passageway for permitting a binding wire to encircle a bundle of articles. A rotary twisting head is disposed adjacent the shells and is provided with two slots for gripping the two crossed ends of the wire which extends around the bundle. The two articulated shells are provided with noselike extensions which overlie the slots disposed in the twisting head for substantially closing the slots and thus providing a positive guide structure for ensuring that the wire is properly fed into and discharged from the passageway formed in the shells.

Claim 1
Independent Claim
310 words
In a binding machine including a frame having a pair of shells pivotally mounted on said frame and movable between open and closed positions, said shells when in the open position being adapted to receive a plurality of articles therein with movement of said shells to the closed position causing said articles to be formed into a bundle, said shells when in the closed position having on their internal faces a continuous passageway for receiving therein a binding wire, twisting means disposed adjacent said shells for coacting with the crossed ends of the wire extending from said passageway for twisting the ends of the wire to form a loop in surrounding relationship to the bundle of articles, said twisting means including a twisting head mounted for rotary movement relative to said frame with said twisting head having first and second slots formed therein for receiving therein the two crossed ends of the wire which extend from the passageway, means for feeding wire into said passageway and for applying traction to said wire for causing same to be snugly disposed around the bundle of articles, clamp means mounted on said frame and disposed for gripping the free end of said wire when said free end extends beyond said passageway, and cutting means for cutting the other end of said wire to the desired length, the improvement comprising guide means for guiding the wire into and out of the respective enTrance and discharge ends of said passageway, said guide means including a noselike extension formed on each of said shells and disposed closely adjacent said twisting head for covering the longitudinal opening of a respective one of said slots when said shells are in the closed position, whereby said noselike extensions in cooperation with said slots define two closed guide passages disposed for direct communication with the opposite ends of said passageway.

In a binding machine including a frame having a pair of shells pivotally mounted on said frame and movable between open and closed positions, said shells when in the open position being adapted to receive a plurality of articles therein with movement of said shells to the closed position causing said articles to be formed into a bundle, said shells when in the closed position having on their internal faces a continuous passageway for receiving therein a binding wire, twisting means disposed adjacent said shells for coacting with the crossed ends of the wire extending from said passageway for twisting the ends of the wire to form a loop in surrounding relationship to the bundle of articles, said twisting means including a twisting head mounted for rotary movement relative to said frame with said twisting head having first and second slots formed therein for receiving therein the two crossed ends of the wire which extend from the passageway, means for feeding wire into said passageway and for applying traction to said wire for causing same to be snugly disposed around the bundle of articles, clamp means mounted on said frame and disposed for gripping the free end of said wire when said free end extends beyond said passageway, and cutting means for cutting the other end of said wire to the desired length, the improvement comprising guide means for guiding the wire into and out of the respective enTrance and discharge ends of said passageway, said guide means including a noselike extension formed on each of said shells and disposed closely adjacent said twisting head for covering the longitudinal opening of a respective one of said slots when said shells are in the closed position, whereby said noselike extensions in cooperation with said slots define two closed guide passages disposed for direct communication with the opposite ends of said passageway.
Claim 3
Dependent Claim
64 words
A binding machine according to claim 1, in which the cutting means includes first and second relatively movable shearing portions, means stationarily mounting said first shearing portion on said frame substantially adjacent the twisting head, and means movably mounting said second shearing portion on said frame for causing movement thereof adjacent to and relative to said first portion for causing shearing of said wire.
Claim 4
Dependent Claim
74 words
A binding machine according to claim 1, in which the clamp means includes a clamp jaw stationarily mounted and fixedly secured to the shell into which the wire is initially fed, and said clamp means further including movable jack means having a movable clamp member disposed for coaction with said stationary clamp member for engaging the free end of the wire therebetween, said jack means being mounted on said last-mentioned shell for movement therewith.
Claim 5
Dependent Claim
63 words
A binding machine according to claim 1, in which the twisting head includes a pair of jaws and means pivotally mounting said jaws for movement toward and away from each other, said jaws when moved to an engaged position defining said pair of slots therebetween, said means pivotally mounting said jaws further including means for permitting limited lateral angular displacement of said jaws.
Claim 6
Dependent Claim
167 words
A binding machine according to claim 1, wherein said pair of shells when in the closed position extend through an angle of substantially 360*, means pivotally mounting one pair of adjacent ends of said shells on said frame for permitting swinging movement of said shells relative to one another and relative to said frame, said twisting head being disposed closely adjacent said one pair of adjacent ends of said shells with one of the slots on said twisting head being aligned with the inlet end of the passageway formed in the wire inlet shell, the other slot on said twisting head being substantially aligned with the discharge end of the passageway formed on the wire discharge shell, the pair of slots being laterally displaced relative to one another and also extending at an angle relative to one another for permitting the adjacent ends of the wire which extend beyond said passageway to intersect, whereby rotation of said twisting head causes said intersecting ends to be bound together.
