Abstract: A mold cleaning apparatus and method is provided for removing debris from an advancing masonry mold product. At least one rotatable tire is arranged at an acute angle to the masonry mold product and engages the mold product to provide a cleaning or scraping force to remove debris from the mold product. The cleaning force of the tire can be adjusted by changing the angle of the tire, the air pressure of the tire or the height of the tire relative to the mold surface. Multiple tires can be employed, while being rotated periodically to evenly distribute wear or replaced as needed.

Abstract: An apparatus for manufacturing simulated masonry products is provided. The apparatus comprises a mold having a mold cavity. The mold cavity has a top surface. An applicator pan is positioned adjacent to the mold. The applicator pan has a screen section positioned above the top surface of the mold cavity. The screen section includes an aperture. The aperture is configured to prevent castable material residing in the applicator pan from flowing through the aperture and into the mold cavity without additional influence A flow mechanism is configured to urge the flow of the castable material through the aperture and into the mold cavity.

Abstract: The invention is a support for the binding and pages of a book stored on a bookshelf. A substantially flat base provides subjacent support when it is inserted in the space between the edges of the pages and the surface of the bookshelf. The support is attached to the book by adhesive strip or by a bookmark. The width of the support's base is adjustable to fit varying thicknesses of books.
