Abstract
842,192. Portable drilling-machines. ARO EQUIPMENT CORPORATION. Jan. 22, 1958 [Nov. 18, 1957], No. 2153/58. Class 83 (3). [Also in Group XXVII] Exhaust from a pneumatic hand-drill passes from a silencing-chamber 50, 52, Fig. 1, in the drill-handle to a hose 58 surrounding the drill supply-hose 18, and which discharges at a remote point, e.g. to the outside of a building wall 62, Fig. 2, and/or into a silencing-box 78, Fig. 5, which may be common to several tools and has a discharge opening 80 of cross-sectional area at least that of the entry-fitting 60b. The supply-hose 18 delivers to the drill motor via a trigger-controlled valve 22 and a duct 40, which feeds two motor entries 44 and lies between two motor exhaust ducts 48 leading from an exhaust annulus 46 to the chamber 50, 52. In a modification, the drill has a handle in line with its chuck.
