The present disclosure relates generally to a bi-directional clamp system and method of use. More particularly, a bi-directional clamp with two clamp bars and two clamping assemblies are described herein. The clamp assemblies have a plurality of arms freely movable in response to a material load is described herein.

A fastener setting tool for installing a fastener into a board structure, comprising a tool body having a bottom surface and a longitudinal axis; a spacer assembly, comprising a first abutment member, having a first engagement surface, and a second abutment member, having a second engagement surface opposingly spaced apart from said first engagement surface, each one of said first and second abutment member extending away from and in a direction normal to said bottom surface of said tool body, said spacer assembly being configured to cooperatingly positioningly engage the board structure; at least one fastener guide operably coupled to any one of said first and second abutment member, and configured to guidingly receive a fastener for the board structure; and a spacer adjustment mechanism, adapted to selectively lockingly move at least one of said first and second abutment member in a direction along said longitudinal axis.

Attachments for a clamping device can be used to increase the contact area between the jaws and the object to allow the clamping device to handle irregular objects, such as non-flat panels of metal, granite, ceramic, glass, quartz, or concrete plates. The attachments can include plate assemblies to be attached to the sides of the irregular objects. The attachments can include jaw plate assemblies to be attached to the sides of the jaws of the clamping device.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

A clamping device is used for joining panels or boards with highly cosmetic appearance at the visible joined surface. The clamping device can include mechanisms to support and move one panel relative to another panel in two directions perpendicular to the beveled edges of the panels. The clamping device can include a rotational mechanism to rotate one panel around a direction parallel to the beveled edge.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include a calibration module for calibrating the magnetic coupling devices.

The inventive technology, in at least one embodiment, may be described as a door leaf handler comprising: a stationary support; a rotatable frame established substantially above [ said ] the stationary support; and wheels configured to allow rotation of [ said ] the rotatable frame about a frame rotation axis, wherein [ said ] the rotatable frame comprises at least one hinge, and door leaf securement rails, and is openable and closeable at [ said ] the at least one hinge along a rotatable frame opening axis. An installer can install hardware on a door leaf secured in the rotatable frame when the installer is in a first position, and then, in order for that installer to be able to install door hardware on an 10 opposite side of the door from that same position, the installer can rotate the rotatable frame, with door secured in it, 180° . Locks and rotational stops, inter alia, can facilitate operation.

An apparatus for applying pressure to at least a portion of an edge surface, which bridges opposing faces of a workpiece, comprises a frame, a first roller, a second roller, a rotation-control member, a first biasing member, and a second biasing member. The first roller and the second roller are coupled to the frame, are rotatable relative to the frame, and are translationally fixed relative to the frame. The rotation-control member is movable relative to the frame, controlling rotation of the first roller and the second roller relative to the frame. The first biasing member is configured to operate in compression along a second axis. The second biasing member is positioned, in compression, between the frame and the rotation-control member.

An alignment system for a workpiece printing machine comprises a stencil support and a workpiece support, and a planarity control mechanism having at least two actuators arranged to effect relative rotation of the stencil support and workpiece support about both the horizontal axes.

The present disclosure is related to a hold-down for a cable tray. The hold-down may be configured for high-wind situations. The hold-down includes a support clamp for clamping onto a support, and a hold-down arm for holding the cable tray on the support.
