    • 12,890. Matthews, W. June 16. No Patent granted (Sealing fee not paid). Cylinder machines with plane printing-surfaces.- Link-work for reciprocating the beds of printing and other machines of the type comprising a radius rod as a, Fig. 1, connected to a link d which is reciprocated by a connecting-rod, is constructed so as to obtain a long throw of the bed without using a machine of great height or providing a pit for the oscillating parts. The invention consists in the use of one or two links d which are connected to the bed by means of telescopic parts g. The links d may be connected together at their upper ends, and are provided with trunnions carrying blocks e which are reciprocated in guides f fixed to the frame of the machine. A connecting-rod j, which is actuated by a crank-pin carried by a pair of wheels'm, is connected to the links d, or preferably to the members g, and as the links d are oscillated the bed reciprocates between the positions h, h , the members g sliding in the link d during the motion. One link d only may be used on a small machine. A buffer-device may be used if required, but the links d act as a buffer and may be loaded so as to increase this action.
