This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 Excerpt: ...broken after being in use some time, it is often desirable to get along without applying them to keep clicks in position. Fig. 197. Fig. 198 shows in elevation a mechanism where no springs are required to keep the clicks in place, it being used in some forms of lawn-mowers to connect the wheels to the revolving cutter when the mower is pushed forward, and to allow a free backward motion of the mower while the cutter still revolves. The ratchet A is usually made on the inside of the wheels carrying the mower, and the piece C, turning on the same axifj as A, carries the three equidistant pawls or clicks B, shaped to move in the cavities provided for them. In any position of C, at least one of the clicks will be held in contact with A by the action of gravity, and any motion of A in the direction of the arrow will be given to the piece C. Here the ratchet-wheel drives the click, ac being the actuated click-lever. The piece C is sometimes attached to a roller by means of the shaft a; then any left-handed motion of C will be given to A, while the righthanded motion will simply cause the clicks to slide over the teeth of A. The clicks B are usually held in place by a cap attached to C. Fig. 199 shows a form of click which is always thrown into action when a left-handed rotation is given to its arm C, while any motion of the wheel A left-handed will immediately throw the click out of action. The wheel A carries a projecting hub d, over which a spring D is fitted so as to move with slight friction. One end of this spring passes between two pins, e, placed upon an arm attached to the click B. When the arm C is turned left-handed, the wheel A and the spring D being stationary, the click B will be thrown toward the wheel by the action of the spring on the pin e. The m...
