摘要： A miter saw with an optical system for projecting an optical alignment marker onto a workpiece. The miter saw has a base, a turntable rotatably supported by the base, a fence disposed above the base for supporting the orientation of the workpiece located on the base, a support coupled to the rear portion of the turntable, and a cutting apparatus including a blade for cutting the workpiece. The cutting apparatus is pivotally coupled to the support for positioning the blade from a raised position above the workpiece to an operational position for engagement with the workpiece. The light projection system is attached to the cutting apparatus for projecting an optical alignment marker onto the workpiece so that the location at which the blade engages the workpiece is in a selectably adjustable relationship with respect to the position of the optical alignment marker on the workpiece. A belt-driven embodiment of the miter saw has an adjustable pulley system comprising a motor connected to a drive pulley, a blade pulley connected to the blade, the blade pulley being in substantial alignment with the drive pulley, and a belt for connecting the drive pulley with the blade pulley. An adjustment mechanism for adjusting the distance between the drive pulley and the blade pulley is provided so that the tension on the drive belt may be adjusted.

摘要： An optical system for projecting an alignment marker on to a workpiece relative to the circular blade of a power saw. The light projection system projects a planar beam of light along a plane defined by one side of the blade to designate the location at which that side of the blade will enter the workpiece. An adjustment mechanism may be included to allow movement of the light projection system so that the planar beam of light can be selectively located parallel to the plane defined by either side of the blade.

摘要： Improvements made to a router relates to a plunge router depth stop system. The depth stop system comprises a depth stop rod contained within a restraining collar coupled to the router housing. The depth stop rod is configured both to rotate at a fixed height above the router base and to slide up and down within the collar in order to adjust its height above the base. At an upper end of the depth stop rod, a turret knob permits an operator to rotate the rod within the collar. At the other end of the rod, a protrusion portion selection member is located to engage selectively one of a plurality of step-wise rising depth stop position surfaces located on the router base. When the protrusion portion selection member is aligned vertically above one of the depth stop position surfaces, the motor housing will plunge until the protrusion portion selection member engages the depth stop position. The operator sets the depth stop height by placing the depth stop rod at the desired height and tightening a restraining collar. Once configured in this position, the motor housing can be repeatably plunged to a desired position. The operator can selectively step the depth downward by keeping the depth stop rod at the desired position while rotating the rod to align the protrusion portion selection member to another depth stop position having a different depth stop height.
摘要翻译： 对路由器的改进涉及一种插入式路由器深度停止系统。 深度停止系统包括一个包含在与路由器壳体相连的限制环内的深度限制杆。 深度限位杆被配置为在路基座底座上方固定的高度旋转，并在轴环内上下滑动，以便调整其高度高于基座。 在深度停止杆的上端，转塔旋钮允许操作者将杆旋转到轴环内。 在杆的另一端处，突出部分选择构件被定位成选择位于路由器基座上的多个逐步升降深度停止位置表面中的一个。 当突起部分选择部件垂直地位于一个深度停止位置表面上时，马达壳体将会滑入直到突出部分选择部件接合深度停止位置。 操作者通过将深度止动杆放置在所需的高度并设置限位环来设定深度停止高度。 一旦配置在该位置，电动机壳体可以重复地插入到期望的位置。 操作者可以通过将深度停止杆保持在期望位置来选择性地向下深度深度，同时旋转杆以将突起部选择构件对准具有不同深度停止高度的另一深度停止位置。

摘要： Improvements made to a router relate to a fine adjust depth stop system. The preferred router comprises a micro-adjust knob coupled to a threaded member within one of a plurality of plunge guide posts. A depth stop nut is coupled to the treaded member such that the nut travels up and down the threaded member as the mirco-adjust knob is rotated. The location of the nut within the plunge guide post defined a depth stop position for the motor housing relative to a router base. When the motor housing is located at the depth stop position, the stop point, and thus the motor housing, will move up and down relative to the base as the micro-adjust knob is rotated.

摘要： Improvements made to a router relate to ergonomic router handles. The preferred router handles are generally elliptical in shape and have one end narrower than the other end. The handles are shaped to provide an operator an infinite number of angles to which the operator's hand may effectively grip the handles. Additionally the handles provide an outer surface which provides a flat tactile grip area. The combination of these elements, along with the shape and location of the preferred trigger and locking arm switch used to activate the preferred router, provides an operator, while operating the router, with the ability to find and use a handle-holding position which is comfortable for the individual user for holding the handles.

摘要： Improvements made to a router include a switching system which is part of a router handle and which operates the router motor by connecting it to an external electrical power source. In a preferred embodiment, the present switching system comprises the use of a locking lever and trigger in combination to activate the motor, to hold the trigger in a locked-on position to maintain the connection of electrical power to the motor, and to lock the movement of the trigger from occurring before an operator attempts to engage the motor. The switching system may also be combined with a preferred router handle shape in order to make the long term operation of the router and its switching comfortable with extended use.
