Abstract: 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.

Abstract: 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.

Abstract: An improved apparatus for opening and closing a door including a hydraulic hinge and a spring-type hinge is provided. The hydraulic hinge includes a rotary member having a first housing, a piston guide placed inside the first housing, a rotary shaft disposed inside the piston guide and a piston screwed with the rotary shaft, and a fixed member having a second housing, a cylinder placed inside the second housing and having an oil outlet penetrating the cylinder for allowing oil to pass through the oil outlet, an outflow part formed on the top surface of the cylinder and having a plurality of support protrusions, a head mounted on the top surface of the cylinder and an adjusting bolt screwed with the head such an oil circulating passage is formed in the fixed member.

Abstract: An automatic swage machine is disclosed which includes an indexing mechanism for indexing a saw along a table enabling a swaging mechanism to sequentially swage each tooth of the saw. The indexing mechanism includes a pair of magnets connected to an indexing arm for pulling the saw forwardly and then move the saw rearwardly enabling the next tooth to be swaged to engage the swaging mechanism.
