Description: |
| Wilhelm, Parker & Hard - patent attorneysThis invention relates more particularly to improvements in wood sawing machines of that class having a pendulous carriage in which the bolt or block to be sawed is held and swung toward and from a vertically arranged circular saw. In these machines a gage is located at one side of the bolt carriage and the bolt is released and moved by the sawyer against the gage to properly gage the thickness of the pieces to be cut prior to each advance movement of the carriage toward the saw. The gage is adjustable toward and from the plane of the saw for regulating the thickness of the pieces which are sawed from the bolt. It is quite often desirable to be able to cut a slab or piece of less thickness than those for which the gage is set, to saw the bolt to the best advantage, or for removing an imperfect portion of the bolt to avoid a knot or knurl in the wood, and for this purpose the present machine is provided with means for quickly shifting the gage whenever desired to a position for sawing such thin piece or pieces and returning it to the normal position. These machines are used for sawing barrel heading, or other slabs or pieces of uniform thickness, and shingles or pieces of wedge shape, and the gage is adapted to be secured in a vertical position for sawing the barrel heading and similar pieces, and to be tilted alternately in opposite directions on a central axis for sawing the shingles and the like. The primary object of this invention is to provide an efficient mechanism of simple, strong, inexpensive and durable construction for quickly shifting the gage from and returning it to the normal position in which it is set for sawing pieces of like thickness. |
