20080236339 | Hand-operated swage device - A hand-operated swage device includes a first hand-operated actuator and a second hand operated actuator that, when actuated together, control the sequential operation of a clamping mechanism and a swaging mechanism of the hand-operated swage device. For example, the first actuator of the swage device is disposed on a first handle while the second actuator is disposed on a second handle of the swage device. To operate the hand-operated swage device, an operator grasps the first handle with one hand and grasps the second handle with his other hand to actuate both of the actuators in a substantially simultaneous manner. Actuation of both actuators controls sequential delivery of pressurized air to a first pneumatic device mechanically coupled to the clamping mechanism and to a second pneumatic device mechanically coupled to the swaging mechanism. | 10-02-2008 |
20080236340 | Swage anvil for a sawblade swage assembly - A swage anvil includes a coupling portion that, when mated with a corresponding die of a swaging device, allows lateral positioning of the swage anvil (i.e., substantially parallel to a long axis of the saw blade) relative to the long axis of the saw blade. The swage anvil also includes a tooth contact face that substantially mirrors an angle of the back portion of each tooth of the saw blade. As such, after a manufacturer inserts the swage anvil into the swage device and laterally translates the swage anvil, the tooth contact face abuts the back portion of the saw blade tooth to support the tooth during a swaging procedure. With the aforementioned configuration of the swage anvil, translation of the swage anvil along a single axis provides support to the back portion of the saw blade tooth along two axes. As such, use of the swage anvil decreases the set-up time required in conventional swaging devices. | 10-02-2008 |

The frame includes an open area near the center of the upper web defining a sharpening area. Clamping screws are associated with the frame to secure the frame to the cutting bar and an additional clamping screw is associated with the frame for engaging the link of the tooth to be sharpened in order to fix its position with respect to the sharpening area of the frame. A rotary burr having an abradant surface is receivable in either of two diagonally disposed, independently removable bore guides for sharpening left-hand and right-hand cutting teeth. | 08-13-2009 |
20110088515 | SHARPENING DEVICE FOR MANUALLY SHARPENING THE CUTTING TEETH OF SAW CHAINS FOR CHAIN SAWS - A sharpening device for manually sharpening the cutting teeth of saw chains for chain saws has a frame, which has two head parts (spaced apart from one another and two pairs of guide rods which are, in each case, arranged parallel to one another and to a longitudinal axis and rigidly connect the head parts to one another. Parallel to the longitudinal axis, round files and two file faces are held without play, but exchangeably in the head parts. The pairs of guide rods and the respective associated round files and the respective file faces are arranged rotationally symmetrically with respect to the longitudinal axis. | 04-21-2011 |
20110120268 | Grinder for Saw Chain - A grinder capable of correctly grinding a cutting blade with a simple operation being provided. Two channels which can be replaced from above on a guide bar in alignment with right and left blades of a saw chain are provided in a base body, a grinding stone shaft is provided on the base separated from the channels by the predetermined same distance while inclined by a predetermined angle relative to a parallel direction to the channels, and a disk grinding stone attached to the grinding stone shaft grinds the side blade and the upper blade of the saw chain simultaneously. The grinder is characterized in that the outer wall of the channel is shorter than the inner wall and contact part contacting the guide bar are formed at lower ends of both walls to make the base horizontal. | 05-26-2011 |

The carriage accommodates the file holder. The carriage is mounted on the placement part in a displaceable manner in a displacement direction transversely to the longitudinal direction of the saw chain. The file holder is guided at an angle to this longitudinal direction and is supported on the cutting tooth to be filed and on the depth limiter. For a guide for the file holder, the carriage has two parallel side guides, which are arranged at a distance from each other, are arranged perpendicularly to the displacement direction, and delimit a receptacle for the file holder. | 11-15-2012 |
