Abstract
A cleaning apparatus (10) is disclosed for cleaning the leg sections (16) of forms such as a double leg form (12). A plurality of individual cleaning brushes (76) are positioned along the length of a brush shaft (64). The brush shaft (64) and cleaning brushes (76) are rotated and the cleaning brushes (76) are urged against the sloping sides (24) of the leg section (16) to clean the sides. As the brushes wear, they can be moved along the shaft in the direction where the sides slope together to obtain maximum use from the brushes. When a brush has become too worn to be effective, it is removed from the section of the brush shaft adjacent the end plate (84). Replacement brushes can be added to the brush shaft adjacent the locking nut (88).
Claims14
A cleaning apparatus for cleaning a surface of a form including a leg section having sloping sides, comprising:
- a frame;
- a brush shaft mounted for rotation on said frame;
- means mounted on said frame for rotating said brush shaft;
- a plurality of brushes positioned along said brush shaft forming a conical brush assembly for rotation with said brush shaft for cleaning the sloping sides of the form, the individual worn brushes being movable along said brush shaft in the direction that the sides of the form slope together so that said worn brushes retain effective cleaning contact with said sloping sides.
A cleaning apparatus for cleaning facing sides of a form, the sides being sloped towards each other in a first direction, comprising:
- a frame;
- a brush shaft rotatably mounted on said frame for extending generally along the sides to be cleaned and generally extending along the first direction;
- means mounted on said frame for rotating the brush shaft;
- and
- a plurality of brushes spaced along a portion of the brush shaft and secured to the brush shaft for rotation therewith, the brushes generally defining a conical brush assembly being urged against the sides of the form as the brush shaft is rotated to clean the sides, each of said brushes being movable in the first direction along said portion of said brush shaft relative to the sides as the brush wears to permit the worn brush to maintain effective cleaning contact with the sides, thereby requiring only replacement of sufficient brushes to maintain effective cleaning contact between the conical brush assembly and the sides.
A cleaning apparatus for cleaning facing sides of a form, the sides sloping towards each other in the downward direction, comprising:
- a frame mounted on wheels for resting on the form above the sloping sides;
- an engine mounted on said frame having a drive shaft extending generally along a first direction;
- a hollow shaft mounted for rotation about a second axis parallel to, but spaced from, the first axis;
- transmission means for interconnecting the engine drive shaft and hollow shaft for joint rotation;
- a brush shaft, said brush shaft having a first section and a second section, said first section having a reduced diameter portion for passing through the hollow shaft and a wedging surface extending outwardly from the reduced diameter portion to abut one end of the hollow shaft, said first section further having fastener means for securing the first section in abutment with the hollow shaft for joint rotation of the hollow shaft and brush shaft;
- said second section of said brush shaft having an end plate at a first end thereof and a threaded portion at the opposite end thereof with a nut threaded thereon;
- and
- a plurality of brushes, each of said brushes including a hub and bristles extending radially outward from said hub, said hub having an aperture therethrough permitting the brushes to be slidable along the second section of said brush shaft between the end plate and said nut, the bristles being of nylon impregnated with silicone carbide abrasive, the brushes being mounted on the second section of said brush shaft for rotation therewith and defining a generally conical brush assembly for cleaning the sloping sides of the form upon rotation of the drive shaft, the brushes being moveable along the second section of the brush shaft in the direction the sides slope inwardly to permit worn brushes to maintain effective cleaning contact with the sides of the form, thereby requiring only replacement of sufficient individual brushes to maintain an effective cleaning contact along the sides of the form.
