Abstract

The elongated handle of the device has L-shaped first and second arms thereon which project in a horizontal plane from the distal end thereof, and the laterals of which depend from the main portions thereof. Interposed in a slot between the first and second arms is a third arm which projects in substantially a vertical plane coinciding with the longitudinal axis of the handle. An inverted U-shaped cowling with bristle arrayed about the inside thereof, is suspended from the third arm and supported on the laterals of the first and second arms, so that the inside surfaces of the skirts of the cowling are disposed to oppose the inside and outside faces of the teeth in a row of the same when the cowling is straddled about the row with the vertical plane of the handle and the three arms generally parallel thereto. Yieldable biasing means in the first and second arms require that the user forcibly wedge the teeth between the inside surfaces of the skirts when the cowling is straddled about the row of teeth, but the main portions of the first and second arms are adapted to resiliently flex in the horizontal plane thereof relative to the vertical plane of the handle, and the points at which the laterals depend from the main portions of the arms are sufficiently spaced apart along the slot from the points at which the main portions connect with the distal end of the handle, that the laterals maintain substantially the original angles thereof to the horizontal plane when the teeth are forcibly wedged between them, so that the bristles on the inside surfaces of the skirts maintain substantially the angles of incidence to the faces of the teeth given them in the design of the device.
