Abstract
The invention provides a manually operable wet sander which uses standard strips or rolls of sandpaper. The sander has a one-piece generally solid body containing a means for removably securing the sandpaper to the sander without piercing the sandpaper. Conduits contained within the sander body regulate the flow of water, or other suitable liquid, from an external pressurized source to a plurality of liquid outlets along both sides of the sander. The water then flows past the edges of the sandpaper strip and onto the surface being sanded. Edge strips are preferably added to direct the water when the surface being worked is vertical or near-vertical or overhanging.
Claims15
A manually operated wet sander having a top surface, a bottom surface, a front, a back, and two sides, comprising:
- a gripping means by which a user can hold sand sander when said sander is in use;
- a means for securing a strip of sandpaper to the bottom surface of said sander, which means securely holds without penetrating said sandpaper along the bottom, front or back of said sander, and without compressing or distorting said gripping means;
- a means for directing a flow of fluid from an external, pressurized fluid source through said sander to a plurality of outlets along the two sides of the sander and out to a surface being sanded, said outlets not penetrating said sandpaper, and said means for directing a flow being adapted to reduce the pressure of the fluid to permit the fluid to provide a substantially constant flow of fluid from the sander onto the surface being sanded.
A manually operated wet sander adapted for use with a garden hose, said sander having a top surface, a bottom surface, a front, a back, and two sides, said sander adapted to hold a strip of sandpaper comprising:
- a contoured handle molded to fit a user's hand and extending upwardly from the top surface so that only a user's smallest finger is positioned to contact the top surface when the sander is gripped;
- a means for securing said strip of sandpaper to the bottom surface of said sander without penetrating said sandpaper and without compressing or distorting said handle;
- a means for directing a relatively high pressure stream of fluid from said garden hose through said sander, said means essentially including a fluid inlet, a plurality of outlets along the two sides of the sander which do not penetrate said sandpaper, and a conduit passing through the interior of said sander from said fluid inlet to each said outlet, said inlet, said outlets and said conduit having a diameter of from about 1/8 inch to about 1/4 inch for reducing the pressure of the fluid stream to provide a substantially constant, low pressure flow of fluid from the sander onto the surface being sanded, said means not including a valve.
