摘要： A frame saw for sawing a relatively thick piece of wooden feed stock simultaneously into a plurality of thinner pieces of wood, and including a feed assembly for continuously feeding the stock from an upstream input position to a downstream output position, and a plurality of closely spaced-apart parallel reciprocable saw blades positioned intermediate the input position and the output position for sawing the stock into thinner pieces of stock as the stock is moved by the feed assembly relative to the blades. A drive assembly is operatively connected to the blades for driving the blades in a reciprocating motion comprising alternate cutting and non-cutting strokes. A linear offset motion assembly is provided for moving the reciprocating blades alternately upstream and downstream into linearly-offset cutting and non-cutting positions relative to the stock. An electronic controller such as an encoder is provided for coordinating the reciprocating movement of the blades and the linear offset motion of the blades to thereby permit continuous movement of the stock while the blades are in both the cutting and non-cutting positions and strokes.
摘要翻译：一种用于将相对厚的木制原料同时切割成多个较薄木材的框架锯，并且包括用于从上游输入位置向下游输出位置连续地供给原料的进料组件，以及多个紧密间隔的 - 平行的可往复运动的锯片位于输入位置和输出位置之间，用于在原料通过进给组件相对于叶片移动时将坯料锯切成更薄的坯料。驱动组件可操作地连接到叶片，用于以往复运动来驱动叶片，包括交替的切割和非切割冲程。提供线性偏移运动组件，用于将往复运动叶片交替地上下游转换成相对于坯料的线性偏移切割位置和非切割位置。提供诸如编码器的电子控制器，用于协调叶片的往复运动和叶片的线性偏移运动，从而允许在刀片处于切割位置和非切割位置和笔划之间时坯料的连续移动。

摘要： A blade clamping device includes a driving shaft and a base member fixedly mounted to the driving shaft. An opening is defined in the base member and a blade is inserted in the base member and connected to the driving shaft. A cam member is pivotably engaged with the opening of the base member and a cam head contacts a side of the blade. The base member is received in a casing which is connected to the electric saw and an opening is defined in the casing. A lever is pivotably engaged with the opening of the casing and includes a pushing end which is located beneath a bar of the cam member so that when pivoting the lever, the pushing end pivots the cam member to remove the cam head from the blade.
摘要翻译：刀片夹持装置包括驱动轴和固定地安装到驱动轴的基部构件。开口被限定在基座构件中，并且叶片插入到基座构件中并且连接到驱动轴。凸轮构件与基部构件的开口可枢转地接合，并且凸轮头与刀片的一侧接触。基部件被容纳在与电动锯相连接的壳体中，并且在壳体中限定开口。杠杆与壳体的开口可枢转地接合，并且包括位于凸轮构件的杆下方的推动端，使得当枢转杆时，推动端枢转凸轮构件以从叶片移除凸轮头。

摘要： A reciprocating gang saw in which each elongated saw blade of a horizontally extending row or gang of parallel, vertically extending such blades is connected at its upper and lower ends with respective upper and lower crank shafts. The crank shafts are supported for rotation about axes extending respectively along the upper and lower ends of the blades. Each shaft has a plurality of cranks that are offset with respect to each other so that the blades successively engage and cut material fed past them at different intervals.
摘要翻译：一种往复式横梁，其中水平延伸的一排或多个平行的垂直延伸的这种叶片的每个细长锯片在其上端和下端与相应的上下曲柄轴连接。曲柄轴被支撑为围绕分别沿着叶片的上端和下端延伸的轴线旋转。每个轴具有相对于彼此偏移的多个曲柄，使得叶片以不同的间隔连续地接合和切割经过它们的材料。

摘要： A crankshaft cradle is provided to damp out vibrations in a gang saw. The cradle is used to support the crankshaft and is pivotally attached to the gang saw frame. Forces that would normally be transferred from the crankshaft to the frame are damped out by means of the movable cradle, the movable cradle being pivotally attached to the frame by pendulum links.
