Latest Patents
One of his latest patents is a side-registering device. This device is designed for the lateral and longitudinal positioning of sheets on the feed table of a printing press. It ensures that the leading edge of the sheet engages a set of front stops while the lateral edge is in contact with a side guide. This innovation enables accurate registered pick-up by a transfer cylinder. The device features laterally swingable wiper members equipped with friction shoes that wipe the sheet towards the side guide while allowing it to move against the front stops. In an alternative embodiment, the friction shoes are secured in the wiping direction but supported with light resilient force to permit simultaneous movement of the sheet in both directions.
Another significant patent is the auxiliary pile board assembly for printing presses. This invention provides temporary support for sheets at the delivery end of a sheet-fed printing press. The assembly consists of a pair of longitudinal rails with cross rails spanning the space between them. It includes a manually operated clamping mechanism that allows for adjustments to accommodate various pile boards, enhancing the versatility of the printing process.
