摘要： Means for connecting a blade to a mower shaft, comprising a member removably secured to the shaft and adapted to carry a blade which extends generally radially from the shaft when the shaft is rotated. The member is bifurcated, having a pair of arms embracing the shaft and may be pivotally secured thereto, and having a center portion joining the arms and to which a blade is adapted to be loosely secured. The member is secured in openings in the shaft by pin means which are either separate from, or integral with, the member. In the latter case, the member is elastically distorted from its normal shape to install the pin means of the member on the shaft, and the member then returns to its normal shape to retain the member on the shaft.

摘要： Blade connecting means comprises a lug member and a retaining member. The lug member and retaining member are adapted to be secured to a mower shaft and to removably secure a mower blade to the mower shaft. The lug member has at least on one end a hook on which the blade is hung, and the retaining member normally engages and closes the hook of the lug member to retain the blade on the hook and, hence, on the shaft. The blade may be easily installed on or removed from the shaft by manipulating the blade to move the retaining member to a position where the hook is open, no tools being necessary to install or remove the blade.
摘要翻译：刀片连接装置包括一个凸起部件和一个保持部件。接头构件和保持构件适于固定在割草机轴上，并将割草机可拆卸地固定在割草机轴上。凸耳构件至少在一个端部上具有挂钩，钩子悬挂在该钩上，并且保持构件通常接合和闭合凸耳构件的钩子，以将刀片保持在钩上，因此将其保持在轴上。刀片可以通过操纵刀片来容易地安装在轴上或从轴上移除，以将保持构件移动到钩子打开的位置，没有必要的工具来安装或拆卸刀片。

摘要： A connection for attaching a mower blade directly to a lug provided on a mower shaft. The blade comprises a pair of resilient fingers cooperating with an opening provided in the lug. The opening in the lug may be circular or non-circular having a long and a short dimension. The long dimension of the non-circular opening is such that when the blade is turned to the long dimension and the fingers are compressed, the fingers will pass through the opening. The short dimension is such that when the blade is turned to such short dimension, the blade cannot be compressed sufficiently to be removed from the opening of the lug. The blade may be removed from the circular opening, regardless of the position of the blade in the opening, by compressing the blade. To connect the blade to the lug of the shaft, the fingers of the blade are gripped in a tool and compressed, and the compressed fingers are then inserted into the opening in the lug. Notches provided in the edges of the fingers are aligned with the margin of the opening in the lug, and the fingers are then released so that the notches loosely engage the lug to retain the blade on the lug. By a converse operation the blade may be removed from the lug.
