Description: |
| This invention relates to certain new and useful improvements in sawing machines and more particularly to trim saws for cutting material at right angles to form a square cut, the object being to provide an electrically operated trim saw which can be rotated at a high rate of speed so as to form a clean cut. Another object of my invention is to provide novel means for mounting the saw in respect to the carriage so that the same can be adjusted in respect to the carriage or table whereby the circumference or the cutting circle of the saw can be shifted so as to adjust it to the proper position. Another object of the invention is to provide a sawing machine in which the motor is so constructed that a clearance is formed for the operator's hands when placing a piece of material on the table or removing the same therefrom, the motor support being adjustable so as to shift the same in respect to the carriage. Another object of my invention is to provide an electric motor in which the driving shaft is so constructed that the saw can be placed on either end thereof to either side of the motor. A still further object of the invention is to provide a novel form of guard for the saw which is adjustable so that the lower edge thereof can be shifted to such a position that it clears the material being sawed. A still further object of the invention is to provide novel means for mounting the table so that it is maintained in such a position that the material thereon will be forced into engagement with the cutting edge of the saw to form a perfect right angle cut, the table being adjustable. Another object of the invention is to provide novel means for limiting the movement of the table in both directions by providing a yieldable bumper in the form of a spring which not only limits the movement of the table, but aids in returning the same. |
