Abstract
9363. Baschy, H., [Firm of]. Sept. 16, 1914, [Convention date]. Percussive hand tools.-In an apparatus for cleaning metal walls, tubes, floors, &c., of the kind comprising a disk-like body having rotatable cleaning-implements projecting from the rim of the body, the implements c are journaled by means of hemispherical studs d on their axes between two disks b so as to be rotatable both in their own plane and in all directions laterally. The cleaning-implements consist of rollers c having peripheral V-shaped grooves c<1> forming two cutting-edges, and are journaled in spirally-curved grooves e in the disks b so as to be thrown outwardly under centrifugal action and to deal a series of blows upon the tubes, floors, &c. when the shaft a is rotated.
