摘要： A circular saw including a frame, a drive means mounted to the frame coupled to a planar saw blade for rotation about a drive axis within a cutting plane and a base pivotably mounted to the frame about a first axis substantially parallel to the cutting plane and a second axis which is generally substantially parallel to the drive axis. In one aspect, the relative pivotal movement of the frame about the first axis is determined by a trim adjuster including disengageable position locator which is operable to provide a plurality of predetermined discrete engaged positions and a locking means for locking the position of the frame relative to the base over a continuous range of settings. The invention also provides a mounting assembly including a course adjustment means and a fine adjustment means to determine the pivotal movement of the frame about the second axis relative to the base.

摘要： A work table for a saw includes a pair of parallel spaced apart horizontally extending guide channels, each guide channel having a vertical web and upper and lower horizontal flanges, the open sides of the channels facing one another; a saw support plate having two pairs of runners for supporting the saw support plate, one pair of runners at one end of the plate and projecting outwardly from the sides of the plate and the other pair of runners at the other end of the plate and projecting outwardly from the sides of the plate. The runners are received within the channels to support the saw support plate in a horizontal plane and the saw support plate is movable in a horizontal plane. The guide channels are provided with apertures in their upper flanges through which the runners may pass, whereby a pair of runners may be lifted from the channels to rotate the saw support in a vertical plane to invert the saw plate and then the runners may be reengaged with the channels. A saw secured to the saw support plate can thus be readily converted from a bench saw mode to a docking saw mode. The work table also includes a work support plate which can be positioned above or below the saw for operation in either mode.
摘要翻译：用于锯的工作台包括一对平行间隔开的水平延伸的导向通道，每个引导通道具有垂直腹板和上下水平凸缘，通道的开放侧面彼此相对; 具有用于支撑锯支撑板的两对流道的锯支撑板，在板的一端处的一对流道，并从板的侧面向外突出，另一对流道在板的另一端突出从板的两侧向外。通道内容纳有水平面支撑锯支撑板的通道，锯支撑板可在水平面上移动。引导通道在其上凸缘中设置有孔，通道可以通过该孔，从而一对流道可以从通道抬起，以使锯支撑件在垂直平面中旋转，以使锯板反转，然后可重新接合流道与渠道。因此，固定到锯支撑板的锯可以容易地从台锯模式转换成对接锯模式。工作台还包括工件支撑板，其可以位于锯的上方或下方，用于在任一模式下操作。

摘要： A work table for a saw includes, a base member supporting elongated guide channels at an elevated position relative to the base member, a saw mounting plate slidably supported in the guide channels, the plate having a rectangular opening over which the base plate or shoe of a commercially available portable power saw is secured, a work supporting plate capable of being removably secured in alternative positions either below the saw supporting plate in which the table operates in the docking saw mode, or above the saw supporting plate in which the table operates in the bench saw mode, the work supporting plate having stops by means of which the saw supporting plate is secured in position when the work table is operating in the bench saw mode. The work supporting plate is formed with slots for receiving the blade of the saw in both modes of operation and for receiving mitre guages and work stops. The work supporting plate is convertible to two different ranges of widths by securing the plate to the work table in different positions.
