Description: |
| This invention provides "blade holding and clamping means in a power driven saw whereby the blade may slip relative to the arbor" when encountering a hard object in the cut or if the sawblade is pinched, while not having the arbor nut tend to tighten as the result of these forces. In this invention the outer end of the arbor is splined which engages with a splined flange, which acts as the arbor washer on the blade. The blade has the ordinary circular mounting hole in the center. The connection between blade and flange is resilient due to the springiness of the flange, which provides a certain resistance to relative motion (slippage) between arbor and blade, the amount of resistance controlled by the spring temper of the clamping flange. The splining prevents any relative motion of the flange, and hence the arbor nut, with respect to the blade. |
