1. A binding machine comprising:
- a body portion;
a ratchet device coupled to said body portion;
a first handle portion including first and second side members, said first and second side members being disposed in substantially parallel spaced relation with respect to one another, said first handle portion being coupled to said ratchet device for rotational activation of said ratchet device;
a second handle portion including third and fourth side members, said third and fourth side members being disposed in substantially parallel spaced relation with respect to one another, said second handle portion being pivotally coupled to said first handle portion at respective mutually proximate ends thereof;
a helical spring, said helical spring being disposed between said first and second side members, said helical spring being adapted to provide a monotonically increasing force in opposition to a pivotal displacement of said first handle portion with respect to said second handle portion;
an inner cross member, said inner cross member having a first end coupled to said first side member and a second end coupled to said second side member, said helical spring having a first end coupled to said inner cross member; and
an outer cross member, said outer cross member having a third end coupled to said third side member and a fourth end coupled to said fourth side member, said helical spring having a second end coupled to said outer cross member.

Abstract
A binding machine includes a tightening mechanism adapted to tension a belt and a limiting mechanism adapted to limit tensioning of the belt. The tightening mechanism includes, for example, a ratchet and a pawl coupled to a body of the tightening mechanism. A handle is adapted to rotate the ratchet in a first direction in response to a first force applied to the handle. The pawl is adapted to prevent the ratchet from returning in a second direction when the first force is released. A spring mechanism allows the handle to indicate when a second force opposing the first force achieves an established magnitude.
