A masonry tool cleaning and storage device may include one or more bins capable of holding water and adapted to hang from the sides of a conventional wheel barrow. The bins may or may not have lids, which may or may not be attached to the bins. The device may optionally include a combined drying table and water return surface adapted to route water, e.g. dripping from wet tools, back to the water bins. The drying table may include a grated surface that is more or less horizontal while assembled in a working configuration. The grated surface may be above a downwardly sloped surface adapted to return water that has fallen through the grated surface back to the bins. When work is complete, the bins may be emptied of water, cleaned, and used for tool storage.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

The present concept is a cutting surface and debris container in combination with a vacuum cleaner. The cutting surface and debris container includes a hollow container with a debris storage compartment, and a cutting surface for supporting a workpiece to be cut. The cutting surface has an opening to allow fresh air to be drawn into the container. The top section of the container has an outlet that can connect to a hose which couples the container to a vacuum cleaner. Debris generated from cutting the workpiece is drawn into the container. Large debris particles drop in the debris storage compartment while small particles are extracted by the vacuum cleaner.

A water supply apparatus for the supply of water to a machine tool, including a water pump, a water accumulator device, a suction line, a supply line and a valve device reversibly adjustable into a first and a second position. The water pump is positioned downstream of the valve device. A first connecting line, a second connecting line and a return line are provided. Here, in the first position, the first connecting line, the second connecting line and the return line are connected to one another such that water can be conveyed from the water pump, from the first connecting line, from the second connecting line, from at least a part of the suction line and from at least a part of the supply line into the return line, and, in the second position, the first connecting line, the second connecting line and the return line are not connected to one another.

Protective cover with cooling for cutter discs; which comprises a generally semi-cylindrical cavity (15) that covers a portion of the cutting disc (2) at the top and that is delimited by two lateral walls (11, 12) and a curved perimeter wall (13). Said cavity (15) internally comprises, in its periphery, fastening means (16, 17) for a tube (3) and a cooling liquid supply nozzle (31) for the disc (2) in at least one upper position (P1) in which the nozzle (31) pours the liquid on the upper end of the disc (2), and one lower position (P5) in which the nozzle (31) sprays the liquid directly against the edge of the disc (2).

Blade guard (20) configured to partially cover a rear face of a circular saw blade (9) while leaving a front face (9b) of the saw blade uncovered. The blade guard comprises: a guard plate (21) having an inner face (21a) configured to face the saw blade (9); and an elongated shielding unit (50) fixed to the guard plate (21) and configured to cover a part of the peripheral edge (14) of the saw blade.

The shielding unit comprises several shielding elements (52) arranged side by side along the shielding unit, each shielding element comprising a shielding member (53) and a resilient cantilever support member (54), wherein the shielding members are arranged side by side in a row in order to form an elongated barrier (55) capable of stopping cutting debris. The support members (54) allow the shielding members (53) to move in relation to each other and in relation to the guard plate (21).

A pipe drilling device includes a casing having a divided structure and externally fitted to a fluid pipe in a sealed manner, a process valve including a process valve body that comes into contact with and separates from a recessed valve seat portion provided inside a neck portion of the casing, a drilling machine including a cutter that is inserted into the casing and configured for drilling the fluid pipe in an uninterrupted flow state, and a cylindrical portion that is movable to open and close an opening of the recessed valve seat portion inside the neck portion.
