2. In a last, the combination, with a stock and an instep-block thereon, of a cap-plate on the comb of the stock, a latch-dog pivoted in a slot on the cap-plate and adapted to latch into a recess in the top of the instep-block, and a spring pressing the dog toward said recess, substantially as described.

3. In a last, the combination, with a laststock, an instep-block thereon, and a capplate held on the comb of the stock by wings on a socket-tube, and pins passing through the stock and wings, of a latch-dog pivoted between depending ears and in a slot in the cap-plate and adapted to enter a recess in the top of the block, and a plate-spring secured by one end in a groove of thelast-stock and pressing the heel of the latch-dog, substantially as described.
