Description: |
| This patent number is reported on the motor-and-gearing housing of a Walker-Turner radial arm saw."This device relates to high speed power transmission and particularly to a device for preventing the breaking of gears incident to a sudden accidental stopping of the driven part. In motor driven geared saws the condition that the present invention undertakes to meet is well illustrated, for in the operation of such machines, all of the factors that heretofore resulted in the breaking of gears in the drive between the saw mandrel and the motor are present. When sawing through a relatively wide plank, for example, the operator holds the plank against the mitre gauge at one side of the line of cut and endeavors to hold and guide that portion of the plank on the other side of the line of cut, freehand, After the saw is part way through the plank, certain very definite forces are released in the plank and the opposed end portions thereof tend to close upon and stop the same."A Walker-Turner radial saw motor housing lists three patent numbers: this one, Canadian patent CA-391,285, and British patent GB-527,508. |
