Portable carpet binding machine

A binding machine comprising:

• a) a housing defining an interior region;
• b) a drive mechanism supported by the housing and at least partially disposed in the interior region, the drive mechanism including a single piece drive shaft;
• c) a prime mover operatively coupled to the drive mechanism for providing motive power to the drive mechanism;
• d) a sewing assembly driven via the drive mechanism for stitching a binding material to an edge of a base material;
• and
• e) a material feeding assembly driven via the drive mechanism including a feed driver mechanism and a coacting puller mechanism operating in substantially synchronous movement to linearly feed the base material relative to the sewing assembly;
• the feed driver mechanism including a feed-dog driven via the drive mechanism that intermittently engages a lower surface of the base material to thereby advance the base material forward;
• the coacting puller mechanism including a first feed roller mounted on a shaft and engaging an upper surface of the base material and being driven by the drive mechanism to pull the base material forward substantially simultaneously with respect to advancement of the base material by the feed-dog of the feed driver mechanism, the first feed roller being disposed above the feed-dog and remains substantially in time with said feed-dog independent of said base material thickness, the first feed roller providing a downward force so that the base material is engaged between the feed-dog and the first feed roller during advancement of the base material, the first feed roller drive shaft driven by the drive mechanism single piece drive shaft wherein the first feed roller drive shaft is substantially parallel to the single piece drive shaft.

A binding machine comprising:

• a) a housing defining an interior region;
• b) a drive mechanism supported by the housing and at least partially disposed in the interior region having a single piece drive shaft, including a first and second eccentric cam integral to said shaft;
• c) a sewing assembly driven via the drive mechanism for sewing a first material to a second material;
• and
• d) a material feeding assembly including a coacting puller mechanism and a feed driver mechanism, both driven by said first and second eccentric cams, respectively, and both operating in substantially synchronous movement to feed the second material relative to the sewing assembly;
• the feed driver mechanism including a feed-dog driven by the drive mechanism that intermittently engages a lower surface of the second material to thereby advance the second material forward;
• the coacting puller mechanism including a first feed roller engaging an upper surface of the second material, the first feed roller being driven by the drive mechanism to pull the second material forward substantially simultaneously with respect to advancement of the second material by the feed-dog of the feed driver mechanism.

A binding machine comprising:

• a) a housing defining an interior region;
• b) a drive mechanism supported by the housing and at least partially disposed in the interior region;
• c) a looper assembly comprising a looper, looper thread, a plurality of apertures, and a connecting rod, whereby the connecting rod comprises a plurality of parts;
• wherein one part of the plurality of parts are links with a pivotal connection between a first and a second link, in the first position of the one link, the looper is positioned for stitching and in the second position of the one link, the looper is retracted for access to the looper for threading.
