Abstract
Abstract An elongated handle has a head at one end. The head has four flat surfaces extending in the longitudinal direction which are arranged into two pairs of opposite parallel surfaces, one pair extending at right angles to the other pair. Each two adjacent surfaces are separated by a rounded edge extending in the longitudinal direction. Bristles disposed in rows extending in said direction extend outward from each of three adjacent surfaces at right angles thereto. Additional non-intersecting rows of bristles also extending in this direction extend outward in a non-intersecting manner from the edges disposed between each of the outer adjacent surfaces and the inner adjacent surface.

299 words
A device adapted to be manually operated to clean dentures by brushing, said device comprising: an elongated handle with a head at one end, said head in cross section defining a rectangle with rounded corners and thus having four flat surfaces extending in the direction of elongation, oppositely disposed surfaces being parallel whereby two pairs of paralleled surfaces extend at right angles to each other, each two adjacent surfaces being interconnected by a rounded edge extending in the direction of elongation; first bristle means secured to a first head surface and including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the first head surface; second bristle means secured to a second head surface parallel to the first head surface and oppositely disposed thereto, said second means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the second surface whereby the first and second means extend outward in opposite directions; third bristle means secured to a third head surface which extends between the first and second surfaces at right angles, said third means including first and second parallel rows of bristles extending in the direction of elongation and extending outward at right angles to the third surface, said third means extending at right angles to the first and second means; and fourth and fifth bristle means, each of the fourth and fifth bristle means including a single row of bristles extending in the direction of elongation and being secured to a corresponding one of the edges between the first, second and third surfaces, each of the fourth and fifth means extending outward at right angles to the corresponding edge and not intersecting with any other means.
