Latest Patents
One of Blume's latest patents is a cover construction for waste containers. This design allows the cover to be vertically raised and lowered for easy access, while also enabling it to roll to either side when open. The cover features special tracks that ride on rollers, facilitating smooth side-to-side movement. When positioned above the opening, notches in the tracks align with the rollers, allowing a sliding plate to lower the cover onto the container for a tight seal. The mechanism operates through crank and screw systems, and the cover can be tipped to rest vertically on either side, supported by hook-shaped levers.
Another significant patent is a latch device for railcar hatch covers. This invention secures the hinged hatch covers of railroad hopper cars. The latch includes a hinge latch plate that swings out of the way when not in use, featuring an opening for a tongue from the hatch cover. A pivotal latch bar engages this tongue, ensuring it remains secure. The design incorporates an over-center effect, requiring the latch to be swung through a pivot arc greater than 90 degrees for release. A heavy-duty version includes double latch plates and bars, along with a roller to facilitate latching and release.
