摘要： A guide for a motorized handsaw which guide includes a track member and clamps which fixedly engage the track and clamp to the underside adjacent edges of the workpiece to be cut by the saw. The clamps include sawable workpiece edge engaging members which extend into the area of the expected saw cut so that they indicate the guided saw line therebetween.

摘要： A dual-knife device for scribing or scoring a wood workpiece before sawing it with a motorized circular handsaw or other saw. The scoring insures a clean saw cut without splintering the wood at the edges, as is required in trimming veneer doors and wall panels. A guide bar is clamped to the workpiece to guide the saw and the scoring device. Prior to sawing, the scoring device is drawn by hand across the workpiece, guided by the same guide bar. The scoring device comprises a pair of knife blades mounted close together on a frame. The knife blades cut two parallel scribe lines or scores into the wood surface, one on each side of the kerf to be sawed. When the saw cut is made, the score lines prevent the saw blade from splintering or feathering the surface of the workpiece along the kerf line, insuring a clean cut.
摘要翻译： 用于在用电动圆形手锯或其他锯切割之前对木材工件进行划线或刻痕的双刀装置。 得分确保了干净的锯切，不会在边缘分裂木材，如修剪单板门和墙板所需。 导杆夹紧在工件上以引导锯和刻痕装置。 在锯切之前，刻划装置由手工穿过工件，由相同的导杆引导。 评分装置包括在框架上靠近地安装的一对刀片。 刀片将两个平行的划线或分数切割成木材表面，每个切割边上的一个切割锯。 当切割锯切时，刻痕线防止锯片沿切割线分裂或刨削工件的表面，确保清洁切割。

摘要： A wood cutting or scarfing and wood sawing apparatus includes a power saw having a pair of mutually spaced scarfing blades positioned in advance of the saw blade and aligned with side edges thereof. The scarfing blades, spring urged into engagement with a wood article being cut, sever surface fibers of the article in the cutting path of the following saw blade. Because the surface fibers are previously cut by the scarfing blades, the saw blade, which may thus be of a conventional crosscut type, does not tear the surface and a clean, smooth edged cut is provided. The apparatus is particularly adapted to laminated wood articles, such as conventional hollow core doors and plywood panels and sheets, which are otherwise difficult and relatively time consuming to cut without splintering. To enable cutting of doors and large panels or sheets, a large article support structure and a saw guideway are provided.
