Gravel Soil Separator Cap

A Materials Sifter Screen

The Gravel Soil Separator Cap is a materials sieve or sifter screen, designed for use with a portable manual or electrically powered cement mixer. Mounting securely over the mouth of the mixer vessel, the Gravel Soil Separator Cap would enable anyone working with undifferentiated materials – soil, sand, and gravel mixtures – to quickly and efficiently separate the materials, according to size, thereby saving time and labor, and conserving materials that would otherwise be wasted.

Features & Benefits

The Gravel Soil Separator Cap is a tough and durable, form-fitting screen, sieve, or sifter, designed to fasten securely and removably over the mouth of a portable cement mixer, thereby converting the mixing vessel into a device by which an undifferentiated mass of materials such as sand, gravel, and soil may be easily separated from one another for further use. As designed and constructed by the inventor, the Gravel Soil Separator Cap consists of a wooden frame, 20 inches in length and width and 3 inches in thickness, which supports a galvanized metal screen or mesh screen or sifter. Variously sized units will also be produced. The top of the frame is square, and the bottom is equipped with miter-cut, diagonal corner braces that give the Separator, from the bottom, an octagonal configuration. This permits the screen to fit securely over the round mouth of the cement mixer. A production model of the Gravel Soil Separator Cap could be produced in a molded thermoplastic polymer; and the Cap might be produced with a series of larger- or smaller-diameter mesh- grid screens to enable the user to sift fine soil if desired. A production model of the Gravel Soil Separator Cap might also be designed with a hinged, opening frame, one that would accommodate (and include in the retail package) a number of differently sized screens for the separation of variously sized materials. The Gravel Soil Separator Cap would be locked in place by a ratchet and strap system which would attach to the mixer. In addition, a steel fork and hook strap could either be included for sale with this product or sold separately for those who use or own a mixer that does not a have a locking mechanism. The Gravel Soil Separator Cap has been designed as an accessory product that will work with gravity to convert a portable manual or electric cement mixer into a highly efficient sifter – a material separator perfect for the smaller concrete and landscaping jobs that involve wheelbarrow-sized loads of sand, soil, and gravel, rather than dumptruck-sized loads or cement-mixer trucks. Easily affordable and easy to use, the Gravel Soil Separator Cap would be the ideal accessory for construction firms specializing in residential construction and remodeling, as well as for those do-it-yourself householders – and there are millions of them – who undertake their own repairs, additions, and renovations. A money and resource saving device, The Gravel Soil Separator Cap would eliminate the waste of perfectly good gravel and soil, as it would separate the two, cleaning the soil of any hard particles and effectively enabling the user to reuse both the gravel and soil (or sand). Clever in conception, thoughtful in design – and already a proven success in prototype form – the Gravel Soil Separator Cap should find a wide and enthusiastic reception in the construction and do-it-yourself markets of America and the world.
