Abstract: In a mower equipped with a grasscatcher, the grasscatcher is attached easily by means projecting upwardly from a deck of the mower, means being integral to a rigid portion of the grasscatcher and embracing the projecting means when the grasscatcher is mounted to the deck, and a block which cooperates with an upper lip on the rigid portion so as to restrain the grasscatcher from being detached unintentionally from the deck if the grasscatcher happens to be bumped from beneath, but so as to enable the grasscatcher to be detached easily.

Abstract: A mechanical clamping device for coupling any an object requiring infinite positioning to a fixed surface and which quickly and easily locks the object firmly in position without the use of electricity or hydraulic fluids. A triple pivoting linkage is employed which magnifies the force applied to a locking lever to thereby facilitate locking of the object in position. The ball seat configuration provides an additional force magnifier at the interface of the ball of the object being clamped and a ball seat defined within the clamping device. An adjusting screw is preferably provided for selectively varying the play between upper and lower clamping plates thereby enabling the clamping force applied to a ball within the device to be varied.

Abstract translation: 一种机械夹紧装置，用于将任何需要无限定位的物体连接到固定表面，并且可快速且容易地将物体牢固地锁定在适当位置，而无需使用电力或液压流体。 采用三重枢转连杆机构，其放大施加到锁定杆的力，从而便于将物体锁定在适当位置。 球座构型在被夹紧的物体的球的界面和限定在夹紧装置内的球座之间提供附加的力放大镜。 优选地设置调节螺钉，用于选择性地改变上夹紧板和下夹板之间的间隙，从而使施加到装置内的球的夹持力变化。
