Abstract: A motorized floor stripper machine includes a motor, a frame, and a blade carrier. The blade carrier is capable of holding blades of different sizes, which can be installed on the blade carrier. The blade carrier is mounted to the frame on shock absorbers. A cam on the frame is connected to the blade carrier by a linkage that includes a bearing block, a pivot plate, a pivot pin, and a support plate. The blade carrier includes ball bearings that fit within linear channels mounted to the frame, so that when the cam is driven in an orbital motion, the blade carrier moves in a generally linear forward-backward motion. The blade carrier is relieved and includes multiple sets of holes for securing blades of different sizes.

Abstract: An electric carpet stapler comprises a trigger and switch assembly that has an actuation caused by a change of state of a sensor, which causes the sensor to send a signal to a control circuit to begin a process to supply power to a winding. The trigger and switch assembly includes a trigger that moves in a trigger actuation direction to move a sensor actuator in a sensor actuation direction, causing a change of state in the sensor, which causes the control circuit to begin the process to supply power to the winding. The trigger and switch assembly may also include a toggle. At the actuation of the trigger and switch assembly, the toggle creates a mechanical instability, and a toggle signal to the user, which may be produced mechanically.

The blade carrier is relieved and includes multiple sets of holes for securing blades of different sizes.
Abstract translation: 电动地板剥皮机包括马达，框架和叶片托架。 刀片载体能够保持不同尺寸的刀片，其可以安装在刀片载体上。 叶片载体安装在减震器上的框架上。 框架上的凸轮通过包括轴承座，枢转板，枢轴销和支撑板的联动件连接到叶片承载件。 叶片载体包括装配在安装到框架上的线性通道内的滚珠轴承，使得当凸轮以轨道运动驱动时，叶片载体以大致线性的向前 - 向后运动运动。 叶片载体被释放并且包括多组用于固定不同尺寸的叶片的孔。

Abstract: A cushion back cutter is formed from a first side plate, a second side plate, and a center plate between the first and second side plates. The center plate includes a slot that forms a blade holding pocket with a bottom opening to receive one or more blades. A blade clamp is inserted into the blade clamp opening of the first side plate, and a blade clamp fastener tightens to cause the blade clamp to press the blades against the second side plate to hold the blades in position. The center side plate forms a row guide for guiding the blades of the cutter between adjacent rows of carpet tufts. The row guide may include a region having continuous notches, which tend to move the carpet tufts out of the path of the blades to avoid shearing them.

Abstract: A cushion back cutter includes finger holes that are shaped to make blade changes and adjustments faster and easier. The cushion back cutter includes a center plate with a recess forming a blade pocket for holding a slotted razor blade. The center plate includes a finger opening for removing a slotted razor blade. The finger opening, which may be non-circular, crosses an upper wall of the blade pocket that supports the blade. A first side plate attached to a first side of the center plate covers the blade pocket in the center plate, and includes a blade window for removing a slotted razor blade from the blade pocket of the center plate. A second side plate is attached to a second side of the center plate, which also includes a finger opening.
