Twenty-three-months afterwards, a reissue was obtained, Containing claims for any.-fprm of foot-lever and hand-lever used in combination for the purpose of-elevating and depressing the runners, and other claims, differing Only in being restricted to a hand.lock-lever used in connection with the foot-lever, or in requiring the two levers to be rigidly connected together.
